Package for dispensing products capable of fluid motion
The invention relates to a package for dispensing products
capable of fluid motion, consisting of a container receiving
the product, having a closure and a re-usable dispensing
facility which features a cap that, after the closure has been
opened, can be fitted onto the container in a sealed manner.
A large number of products capable of fluid motion e.g.
dry-pourable, liquid and pasty products are today offered in
packages from which they can be directly dispensed, dispersed,
expressed or sprayed in desired amounts. Examples which may be
mentioned are cosmetics, medicaments, foodstuffs and
flavouring agents, cleaning and personal health care agents as
well as paints and varnishes. Widespread use has been gained
in this context by aerosol cans, which are designed as sealed
packages of metal or plastic and contain along with the actual
consumer product a propellent gas or a gas-generating
compound. In many cases use has also been made of dispensing
facilities in the form of mechanical spray devices that
function after the fashion of a pump, without propellent gas.
These are fitted onto the container which consists of glass,
plastic or metal. For this purpose, the container has a neck
with external thread onto which a spray device cap with
internal thread is placed and screwed in a sealed manner onto
the container. The spray device has, furthermore, a dip tube
which reaches as far as the bottom of the container. By means
of a pump which can be operated by the fingers, in particular
by the thumb, the liquid is sucked in or forced into the dip
tube and fed to the atomization nozzle.
~r
1 320458
It is furthermore known, in particular for the dispensing of
pasty products, to provide the dispensing device, likewise
operating in the manner of a pump, as a reusable part and,
once a container has been emptied, to screw it onto a new,
filled container. In this case, however, there is no atomizing
dispensing but a portioned dispensing of the product.
All known packages of the design mentioned above have the
disadvantage that at least the container consisting of
plastic, metal or glass has a large space requirement in waste
disposal and cannot be recycled, or only with considerable
effort. The raw materials for the production of such
containers are also relatively expensive, or the energy costs
necessary for their production are very high.
In the case of complex and expensive spraying instruments
e.g. paint and varnish spray guns, it is known (DE-C-35 17
122) to provide the spray device with a recepticle which
accommodates a container holding the fluid to be sprayed. The
container is in the form of a one-way disposable package of
plastic or cardboard. The recepticle features a piercing means
with suction bore, and the container inserted in the
recepticle in such a way that the piercing means penetrates
the end of the container thus allowing the fluid to flow into
the spray gun. By this means it is not possible to produce a
fluid-tight seal. In another version which enables a tight
seal to be formed, the container features at its base a valve
of complex design that can be opened by the piercing means of
the recepticle. Because of the complex design of the valve,
the container is expensive and should therefore be re-usable
i.e. refilled, which calls for an appropriate design of the
container lid.
1 320458
The object o~ thc invention is to create a package of the kind
described at the beginnin~ in such a way that it can be
manufactured at favourable cost and can be used equally well
with complex and with functionally optimised dispensing
facilities. Furthermore it is intended that the package, after
consumption of the product, can for the greater part be
directed for unproblematic waste disposal or for recycling.
Also the container should be disigned in such a manner that it
can be combined with any form of dispensing facility,
possibly of complex construction and, independent of contents,
permits proper, complete emptying.
This object is achieved according to the invention in that the
container consists of a sleeve of composite cardboard or
paper material and at least one sealable plastic layer on the
inside, a bottom that is sealed onto the inner side of the
sleeve, and a closure membrane that is sealed onto the other
end of the sleeve and can be partially or wholly opened, and
in that the dispensing facility can be secured to the end of
the sleeve by means of the cap.
Although packages out of composite cardboard containers are
used in large numbers, they primarily serve for the packaging
of pourable products, such as powder or the like, or else
doughy to pasty products, such as jams etc., more rarely for
liquids, such as juices or the like. Due to their lack of
dimensional stability and the difficulty of attaching a
releasable, but at the same time sealed closure, such
composite cardboard or paper containers have hitherto not been
used for packages with dispensing facilities, in particular
controlled supply or spraying devices or the like. The problem
of attaching a releasable closure, or even a dispensing
device, for example a spraying or pumping device, also arises
1 320458
from the fact that the sleeve consisting of the cardboard or
paper composite is designed with tne same cross-section over
its entire height and cannot be provided with an external
thread or the like in order to be able to fit the dispensing
or spraying device. This is where the invention effectively
provides a remedy in that the container does not have a
releasable closure but instead a sealed-on closure membrane
with an opening that is broken open wholly or partially only
when being put into use, while the cap of the dispensing
facility can be fixed onto the end face of the container.
The packaged product can thus be stored and offered in a
tightly sealed container of the simplest and most inexpensive
design, and the dispensing facility can be brought into
connection with the container without any problems. Once the
container has been emptied, the dispensing facility can be
removed and fitted onto a new container with sealed-on closure
meMbrane. The dispensing facility is thus reusable, while the
emptied container is discarded. Due to its low dimensional
stability, in particular in the emptied state, the container
can be crushed without problem and thus takes up little
space. In waste disposal, for example in refuse incineration
plants, the greatest part of the container viz., the entire
sleeve of cardboard or paper composite material can be burned
and converted into thermal energy.
The dispensing facility can be in the form of a manually
operated control feed device e.g. in the form of a dispersing
device, a spraying device or the like. In the case of
liquid or pasty contents the sleeve of cardboard or paper
composite material is provided with a, for example metallic,
barrier layer e.g. in the form of a metal foil. In that case
it is furthermore provided for the dispensing facility to be a
1 320458
spray device with a hand pump having a dip tube that reaches
almost to the bottom of the container.
A preferred version is such that the closure membrane features
a prepared opening that can be broken open. This opening is
broken open before or during the joining of the dispensing
facility to the container so that the contents can be removed
by the dispensing facility.
The closure membrane and/or the bottom can consist of a metal
foil Wit}l at least one sealable plastic layer arranged on the
inside. This version has the advantage that the container has
little weight and can be made such that it is air-tight i.e.
does not allow fluids or gases (aromas) to escape.
Instead it can be provided that the closure membrane and/or
the bottom consists of composite cardboard or paper material
having at least one sealable plastic layer arranged on the
inside. As a result the metal fraction is reduced further and
the combustible fraction for energy recovery disposal
increased. For those cases where a fluid-tight or gas-tight
container is required with this version it is also possible to
employ a metallic barrier layer.
The closure membrane and/or the bottom is/are preferably drawn
into the sleeve and sealed outside and inside onto the sleeve.
A further advantageous version is such that the bottom of the
container slopes in the form of a depression towards the
centre. In the case of the dispensing facility being in the
form of a spray device the dip tube can reach down to the
depression so that, on standing the container upright,
1 320458
complete emptying of the container is assured. The dip tube
can, however, also terminate a distance above the depression
in order to avoid sediment being sucked up the tube. Moreover
this shaping of the container bottom contributes to the
stabilisation of the same which is important in particular if
it is made of a metal foil.
As the membrane forming the container bottom should also be as
thin as possible - in the range of some ~m - it can be
embossed essentially in a radial direction in order to
stabilise the bottom and to prevent uncontrolled bulging
during filling and/or shaking of the contents.
Packaging with a sleeve of cardboard or paper composite
material, especially if their wall thickness is small, have
the disadvantage of low shape stability. Round sleeves tend to
become oval. This makes the package unattractive and makes it
difficult or even impossible to mount the ejector unit. To
avoid this, it is foreseen to insert in the sleeve, in front
of the closure membrane at the lid end, a paperboard disc of
the same shape as the cross-section of the container.
A further measure for increasing the shape stability is the
insertion of a paperboard disc of the same shape as the
container cross-section in front of the bottom at the bottom
end of the container.
The paperboard discs can be glued, sealed or inserted in a
push-fit manner. In each case, however, at least the paper-
board disc on the lid end is releasably mounted and features atab which allows the said disc to be removed before mounting
the dispensing facility on the container. The sleeve is then
stabilised by the cap of the dispensing facility and by the
1 320458
pal~erboard disc at the bottom, if present, also during use.
In a further advantageous development it is provided that the
break-out opening on the closure membrane is stamped into the
metal foil, cardboard or paper composite material and is
closed off by a sealed-on foil or by the sealable plastic
layer of the closure membrane lying on the inside.
In the case of known drink packages it is known to provide the
container with an opening closed by a sealed-on foil, to be
able, for example, to introduce a drinking straw. In the case
of the design according to the invention, the sealed opening
fulfils the task of receiving the dip tube of the spraying
device. With an approximately same cross-section of opening
and dip tube, the dip tube is additionally positioned and
centered. The opening can, however, also be designed to be
larger in order that on tilting the package any fluid
overflowing into the space between the cap and the closure
membrane can be allowed to flow back into the bulk of the
container. For the same purpose it can be favourable also to
provide the closure membrane with a depression.
In a preferred embodiment, it is provided that the neckless
sleeve at the end with the closure membrane is widened
outwards, forming a locking rim for the cap. Due to the
widening of the opening on the one neckless end of the sleeve,
a type of outer annular bead is produced, which serves for the
fitting of the cap of the dispensing facility. In this case it
is possible in particular to achieve an adequately good
sealing at the locking rim to make it possible to pump out the
contents by means of a spray device. It is possible,
furthermore, to provide the container straight away with a
1 320458
dispensing facility when it is first produced so that, having
purchased such a package, the consumer later need buy only
individual containers with the product while the dispensing
facility can be repeatedly reused.
In order to obtain a sealed closure, in particular for the
initial purchase of the package with the fitted dispensing
facility, in a preferred embodiment the cap has a resilient
rim flange overlapping the locking rim of the sleeve on
outside and inside. Such a resilient overlap makes possible on
the one hand the fitting of the dispensing facility onto the
container and leads on the other hand to a sealed closing-off
of the rim on the inside, which prevents the escape or
evaporation of the packaged product with fitted dispensing
facility.
It is advantageously provided that the rim flange is formed by
an annular lip bearing in a sealed manner against the sleeve
on the inside and by a locking rim resiliently overlapping the
sleeve on the outside.
According to a further exemplary embodiment, the sealing can
be improved still further in that the rim flange has a
dimensionally stable collar ring overlapping it.
Once the cap has been fitted, the dimensionally stable collar
ring is pressed over the rim flange or else is screwed onto a
corresponding external thread of the rim flange, so that the
part of the rim flange on the outside cannot spring back and
the cap is fixed firmly on the container, and consequently so
is the dispensing facility. This design is also recommendable
in particular whenever the container is offered with fitted
dispensing facility as a retail package.
1 320458
Instead of this, it may also be provided that an annular cover
part of plastic is welded, stuck or injection-moulded onto the
end face of the neckless sleeve, the annular opening of which
cover part is closed by the closure membrane and on which the
dispensing facility can be fixed with its cap.
In the case of this design, the closure membrane is thus not
directly fastened to the sleeve of the container, but to the
cover part. The stuck, welded or moulded-on cover part acts at
the same time as a reinforcing ring for the sleeve, so that
the latter can be produced with a relatively thin wall, thus
saving material. The same applies whenever the cover part is
moulded-on~ as in this case it is also possible to use a
smaller amount of material for the cover part than in separate
production.
It is preferably provided that the annular cover part has a
sleeve-shaped extension protruding into the sleeve of the
container, by which extension it is fastened to the sleeve by
welding, adhesion or injection-moulding. ~ith this design, the
sealing takes place on the inside of the container, so that
the packaged product cannot penetrate to the end edge, at
which there is generally a free cut edge of the composite
material.
A further advantageous exemplary embodiment is characterized
in that the annular cover part consists of a plastic which can
be welded to the inside plastic layer. In this way, sleeve and
cover part can be welded without any problems, whether by
simple heating if a separately produced cover part is used or
in moulding-on of the cover part. Moulding-on has the
advantage that unevennesses in the wall of the sleeve, which
there always are with composite material, in particular if the
1 320458
sleeve is produced by the conventional winding process, can be
compensated for.
A further advantageous exemplary embodiment is characterized
in that, when the package is first produced, the cap has, as
originality closure, a retaining ring enclosing the sleeve on
the outside and connected to the rim flange via predetermined
breaking tabs.
The container designed according to the invention can comprise
essentially of at least up to 75~, preferably up to 90~ of
recycled paper or cardboard. Consequenily, not only can the
container according to the invention be produced out of
inexpensive used material, but can with the same large weight
fraction be combusted in refuse incineration plants to recover
the thermal energy content.
The invention relates furthermore to a package comprising a
sleeve of composite cardboard or paper material having a
sealed-on bottom and on the opposite end a sealed-on closure
membrane that can be partially or completely opened, also a
cap that overlaps the sleeve with closure membrane, said cap
being in particular, but not exclusively, in conjunction ~ith
a dispensing facility. A cap for such a container is
characterized according to the invention in that it features a
rim flange in the form of a cutting ring overlapping the
sleeve on the outside, which cutting ring cuts into the
composite material when screwed onto the sleeve.
In the case of this design of the cap, the invention utilizes
the fact that the composite cardboard or paper material is
relatively soft and compliant, in particular it is also easy
to deform permanently. By screwing the cap onto the sleeve,
1 320458
"
the cutting ring works into the composite material in the
manner of a thread, so that the cap receives a firm seat on
the sleeve. In this case, the cutting ring can, furthermore,
be designed such that - even with opened closure membrane - a
sealed closing-off is provided at the same time for the
container. Such a cap can be used for composite cardboard or
paper cylindrical containers of any design and with any filled
product. It is, however, also suitable in particular for
forming the previously described cap of the dispensing
facility and for screwing onto the container after fitting the
dispensing facility, in order to fix that facility on the
sleeve. Once the container has been emptied, the dispensing
facility can be removed in a similarly simple way and fitted
again onto the next filled container. If the cap can be
employed for closing off containers with other consumer
products, then it can be re-used, while the container itself
is discarded after emptying.
The cutting ring preferably has a multiple internal thread,
each course of the thread expediently having a relatively
large pitch in order to fix the cap on the container with one
or just a few turns and to achieve a particularly effective
seal.
It is furthermore of advantage for the inner thread to have an
inner diameter that diminishes with increasing distance from
the free end of the cap towards its interior. In conjunction
with the further measure viz., that a backing ring is arranged
in the interior of the cap a distance from the inner thread,
and that the distance between the backing ring and the
1 320458
inner thread, at least in the region of the smallest inner
diameter of the inner thread, is smaller than the wall
thickness of the cap, a great advantage is derived in that on
the one hand the screwing on of the cutting ring is made
easier, and on the other hand the sleeve is squeezed between
the thread and the backing ring so that a perfect seal is
obtained.
In a modified embodiment it is provided that the sleeve, at
least in the region overlapped by the cutting ring, features
greater compliance. By this design the deformability of the
sleeve can be improved in its region receiving the cap so that
the cap can be screwed more easily and effectively onto the
sleeve.
The above mentioned embodiment can be realised in multiple
ways, for example, in that the sleeve features a greater wall
thickness at least in the region overlapped by the cutting
ring. Such a greater wall thickness is easiest achieved by the
provision of a bandage in the region of the sleeve overlapped
by the cutting ring, it being possible for the bandage to be
sealed, stuck or welded onto the sleeve and possibly, to be
made of a softer material.
Instead of that, it is of course also conceivable for the
sleeve to feature on the outside a softer layer that, for
example, is made of a thin laminate layer of foam-foil, a soft
paper layer, possibly also in the form of the label material
applied to the sleeve.
In order to make it easier to screw on the cutting ring it can
be provided that the sleeve, on the outside in the region
1 320458
13
overlapped by the cutting ring, features entry grooves for the
inner thread of the cutting ring.
If the container features a metallic closure membrane, the
edge of which is sealed to the outside of the sleeve, then in
specific cases it can be particularly difficult to screw the
cap with the cutting ring onto the sleeve. In this case at
least the membrane rim can be provided with moulded-in entry
grooves for the cutting ring. These entry grooves can be
formed in the sleeve and/or in the edge of the closure
membrane without any difficulty by means of pressing or
rolling. At the same time these entry grooves provide a means
of guidance for the cap when it is being screwed on.
Instead of that or in addition the screwing-on of the cap can
be made easier in that, when employing a metal closure
membrane which is sealed by its rim to the outside of the
sleeve, the sleeve has a smaller outer diameter over the
height of this rim, and the cutting ring is greater in height
than the rim of the closure membrane, so that the cutting ring
cuts into the sleeve below this rim. With this embodiment
therefore the cap simply overlaps the rim of the closure
membrane and the cutting ring is turned, cutting into the
free, exposed outer surface.
The abovementioned cap may have an annular lip bearing in a
sealed manner against the sleeve on the inside. Instead of
this, of course an annular seal may also be inserted into the
cap in a conventional way.

Figure 11 shows a sectioned view of part of a package having
another design.
The package for products capable of fluid motion in particular
liquid products, represented in Fig. 1, has a container 1 and
a dispensing facility 2 in the form of a spraying device. The
container 1 consists of a cylindrical, for example
circular-cylindrical, oval or else of a polygonal sleeve 3, a
bottom 4 and a closure membrane 5 forming the upper closure.
The spraying device 2 has a dip tube 6, which reaches to the
bottom of the package, and a cap 7, which is locked onto the
container 1. The spraying device 2 has, furthermore, a grip 8
in the form of a pushbutton, by the activation of which a pump
(not shown3 is driven, which delivers the liquid in the
container 1 to an atomization nozzle 9.
The sleeve 3 is, as shown in figures 1a and lb produced from a
possibly m~lti-layered composite cardboard or paper laminate
50, and in the case of liquid, pasty or moisture-sensitive
contents features a layer 51 acting as a barrier to liquid,
and cornprising for example a metal foil. This can in turn be
arranged inside, outside or within the composite cardboard or
paper laminate. The sleeve 3 is provided on its inside 10, and
possibly on its outside 11, with a sealable plastic coating 52
or 53, by which the bottom 4 and the closure membrane 5 can be
sealed thermally or by high frequency. For this purpose the
bottom 4, as figure 1a shows, and also the closure membrane 5
is produced as a deep-drawn part from a metal foil 54 or
1 32045~
16
likewise from cardboard composite 55 (fig. 1b) with a sealable
plastic coating 56 or 57, and is flanged with its rim 58
around the end face 59 of the sleeve 3 and sealed-on, inside
and outside.
The closure membrane 5 has in its centre a prepared opening
13, which is closed by a foil 14 sealed onto the rear of the
closure membrane S and is possibly protected from the outside
by a cover (not shown). Instead of the foil section 14 shown,
the closure of the opening 13 may also be formed by the
sealable coating of the closure membrane 5.
The end rim 12 of the sleeve 3 is, as evident from Fig. 2,
bent outwards by widening of the end opening, so that a
locking rim 15 for the cap 7 of the spraying device 2 is
produced. For this purpose, the cap 7 has a rim flange 16,
which is formed by an annular lip bearing 17 arranged on the
inside and locking ring 1 a arranged on the outside. The
annular lip 17 is almost rigid in design in order to be able
to perform a sealing function, while the locking ring 18 can
spring out in radial direction, so that the cap 7 can be
clipped onto the lock1ng rim 15, the annular lip 17 in
particular ensuring a sealed closure. In order to avoid a
spreading-open of the locking ring 18, in particular when the
complete unit comprising container 1 and spraying device 2 is
offered as a retail package, a dimensionally stable collar
ring 19 may be provided, which is guided on a corresponding
extension 20 of the cap 7 and overlaps the locking ring 18 by
a downwardly reaching annular part 21. This collar ring 1 may
be designed as a sliding part or else have an internal thread,
which interacts with a corresponding external thread on the
locking ring 18.
1 320458
17
In ~he case of the exemplary embodiment according to Figure 3,
on the rim flange 16 there is attached via predetermined
breaking tabs 22 a retaining ring 23, which prevents an
inopportune lifting-off of the cap 7 and at the same time
serves as originality closure. In order to be able to remove
and reuse the spraying device once the container 1 has been
emptied, the retaining ring 23 is torn off, so that the cap 7
can be removed with the spraying device 2. As Figure 3 further
shows, the sleeve 3 is also widened at its end face at the
bottom, in order to form in this way an enlarged stand ring
24, which is recommendable in particular in the case of
containers having a large ratio of height to diameter.
In order to improve the low dimensional stability of the
package, in particular that of the sleeve, a paperboard disc
25 can be inserted (figure 4), said disc for example residing
securely in place by virtue of push-fit, or any other manner,
in a groove pressed into i.2. recessed in the sleeve 3.
Likewise, in the case of subsequently purchased packages
without the spraying device 2, a paperboard disc 27 can be
mounted on top of the closure membrane 5 and secured there by
push-fit means in a prepared groove. The paperboard disc 27
must be releaseable, for which purpose it features a tab 29
for gripping; after removal of the disc the spraying device 2
can then be mounted into place.
In order for the membrane-like bottom 4 to have a better
dimensional stability at small wall thickness, a radially
symmetric embossment 30 can, as shown in figure 5, be provided
in it.
1 320458
18
Figure 6 shows an embodiment in which the sleeve 3 at least at
its upper end terminates cylindrically with the diameter of
the sleeve. The cap 7 features an edge flange 16 which in turn
is provided with an inner annular lip 17 that acts as a seal.
The part of the cap 7 that overlaps the sleeve on the outside
is, in contrast to the abovementioned embodiments, rigid and
in the form of a cutting ring 31. In the version shown it
features a multi-pitch inner thread 32 which on screwing the
cap 7 onto the sleeve 3 cuts into the relatively soft
composite material. An additional seal is provided inside by
means of the annular lip 17. To make it easier to screw on,
the cap 7 can be provided on the outside with a profiled
surface.
Figure 7 shows an embodiment with a cap 7 such as may be used
also for other containers of the same design. It features
again a cutting ring 31, however the thread 32 is, as shown
in the drawing, provided with a pitch that increases in the
inwards direction and inner diameter that likewise decreases.
A distance from the inner lying thread is a backing ring 33.
The width of the gap thus created between the backing ring 33
and the inner thread 32 decreases inwards from the free, open
end of the cap, and as such narrows down to a width that is
smaller than the thickness of the wall of the sleeve 3, so
that the sleeve wall in the region is squeezed together on
screwing on the cutting ring. This way a tight seal on the
container is obtained even after multiple use. In the case of
this embodiment the rim of the closure membrane terminates at
the upper end of the sleeve.
In the exemplified embodiment according to figure 8 the sleeve
1 320458
1 9
features, in the region overlapped by the edge 34 of the
closure membrane, a smaller outer diameter than the other
regions, i.e. the outer face is recessed inwards. The cutting
ring 31 is in this case arranged lower on the cap 7 so that
the inner-lying thread 32 need only be turned into the
material of the sleeve 3, but not into the much harder
material of the closure membrane 5.
In the case of the exemplary embodiment according to Figure 9,
the cap 7 again has a cutting ring 31 overlapping the sleeve 3
on the outside and having a multiple, steep thread 32. The
sleeve 3 is, however, provided in its rim region on the
outside with a bandage 35, which on the one hand stabilizes
the rim region, but on the other hand leads to a greater
compliance and deformability in the outer region, so that the
cutting ring 31 can be screwed on more easily. The cap 7 can
in turn receive a dispenser insert 2 in a central hole 36. The
bandage 35 may consist of the same composite material as the
sleeve 3 or else of another, in particular a softer, material.
Furthermore a seal 37 can be provided between the cap 7 and
the upper edge of the sleeve 3 or the rim of the closure
membrane which is secured there, this in order to obtain a
tight closure in the edge region when the cap is closed.
In Figure 10, a container 1 is shown with a sleeve 3, onto the
end face of which a closure membrane 5 is sealed by the
closure membrane 5 being folded outwards with its rim 38 over
the sleeve 3 and sealed onto the outer plastics coating of the
sleeve 3. In order to make it possible also in this case to
achieve an easy screwing-on of a cap 7 with cutting ring 31
entry grooves 39 may be moulded into the overlapping rim 38 of
1 320458
the closure membrane S.
Figure 11 shows an exemplary embodiment of a container 1, the
sleeve 3 of which has a core 40 of possibly multiple paper or
cardboard layers, possibly also with a metallic barrier
layer. This core 40 is, as already described at the beginning,
provided on its inside with a plastics coating 41 and possibly
also on its outside with a plastics coating 42. Onto the end
face of the neckless sleeve 3 is moulded the annular cover
part 43, which consists of a plastic affine to the inside
plastics coating 41, so that the inner coating 41 and the
cover part 43 fuse together in the region of the latter's
sleeve-shaped extension 44, which engages into the sleeve 3.
The free face edge of the sleeve 3, in particular of the core
` 15 40, is covered in a sealed manner by an overlapping rim 45 of
the cover part 43. The cover part 43 has in turn a central
opening 46, which is closed by a closure membrane 5 and can
serve for receiving a dispensing facility 2. For this purpose
the cover part 43 features a bead 47 onto which the dispensing
facility can be clipped on.
As already indicated the dispensing facility can, depending on
the contents, be a spraying facility, a dispersion facility,
an expressing facility or the like. The container can also
serve as a refill package for mechanically operating spray and
distributor facilities.
