Transport package for containers having a circular
cross section
The present invention relates to a transport package for
containers of circular cross section displaying a tray and
a hood.
In the most widely divergent fields, the most varying goods
are packaged in containers having a relatively small
volume. ~or the transport of these small containers special
packages are required, which assemble these small
containers into a larger unit. As a rule, these transport
packages are in turn assembled into evan larger units for
the transport of large amounts of the particular goods.
:
~ What is described is a transport package for containers
; having a circular cross section, consequently a unit which
assembles several of the smallest package units. These
transport packages are commonly assembled again into even
larger units, usually packaging pallets.
For tha packaging of individual containers, transport
packages can be used consisting of a lower part, which can
also be referred to as tray, and an upper part. Usually,
the upper part is placed over the lower part, thus forming
a transport package which is closed on all sides.
It has appeared that special transport packages are needed
~or those containers that have a circular cross section, in
particular for glass jars~
The object of the present invention is therefore a
~ 30 transport package for containers having a circular cross
;~l section, in particular glass jars, which display a tray and
, a hood. The side walls o~ the hood, which are arranged in

parallel, display recesses in the places where the
containers of circular cross section, which are placed side
by side in the transport package/ exhibit the largest
expansion parallel to the bottom plate. This largest
expansion therefore corresponds with the sum of the
diameter of the juxtaposed containers. Usually, containers
having a circular cross section are arranged side by side
in one or more rows and are enclosed by the transport
package, which essentially has a rectangular shape, since
the transport packages and the units, into which the
indiviual transport packages are assembled, usually have
the shape of a cube or parallelepiped.
~ The transport package described herein now exhibits
`~ 15 recesses in the side walls of the hood. These recesses can
assume the shape of a turned U or also be rectangular.
These recesses can extend as far as the under-side of the
hood and, when several are provided side by side, can be
given a shape reminiscent of a comb. When, however~ the
recesses do not extend as far as the under-side o~ the side
; wall of the hood, the recesses are entirely enclosed by the
side walls of the hood.
: .
;~ Usually, the transport package has the shape of a cube or a
parallelepepid. Consequently, the hood has a rectangular or
square covering plate and at least two sida walls fac:ing
each other. To increase the stability o~ the transport
package, the hood can, however, display four side walls,
whereby each time two side walls are arranged such as to
face each other and are linked with one side to the
coverin~ plate.
The transport package consists o~ the lower part, which is
referred to as tray, and the hood, which is placed over the
containers having a circular cross sectionr in particular
` glass jars.

3 Q 7141 (R)
Since the transport package should adequately keep together
the containers arranged therein, it is often desirable that
lower part and hood be connected. This connection can be
made with the aid of adhesive, which is applied in liquid
state, or adhesive tape.
In a preferred embodiment, however, the hood and the tray
are connected by one or more flaps and the relevant insert
recessO In the side wall, or side walls~ of the tray
lo trilaterally punched insert flaps are formed, which are
linked on one side. The connecting side between insert flap
and side wall is then either arranged in parallel to the
bottom plate of the tray or at right angles thereto. The
flap is preferably trapezoidal. In a further preferred
embodiment, two trapezoidal flaps are provided side by side
in such a way that the side of the trapezium, which is
parallel to the two linked sides, is ~ormed by a common
incision.
When the hood is placed over the containers that are in the
tray, the non-recessed parts of the side wall o~ the hood
are placed into the tray at the lower edge ~f the side
walls so that the non-recessed parts of the lower side
~; edges of the hood are each time provided inside the side
walls of the tray. In the places where insert flaps are
formed by incisions in the side walls of the trays, insert
;~ recesses are provided in the side walls of the hood. These
insert recesses are shaped such that the insert flaps of
the side walls of the tray can be introduced into the
insert recesses by folding. By introduction of the flap
into the insert recess and folding of the flap, a firm
connection between hood and tray is formed. The insert
recess can be designed such that a corresponding opening is
punched into side wall of the hood, or the insert recess
can be punched only on three sides and linked on one side.
Upon insertion of the flap, this is folded inwards together

with the part of the side wall of the hood covering the
insert recess. The folded parts, thus the insert flap and
the part of the side wall where the insert recess is
located, can then be secured tightly to the containers
contained in the transport package, as a result of which,
on the one hand, reinforcement oP the connection between
hood and tray is achieved and, on the other hand, a better
fit of the containers contained in the transport package
can be reached. Preferably, the incisisns by which the
insert flap or the insert recess is formed, are provided
such that trapezoidal flaps or insert recesses are formed.
Dependent upon the size of the transport package a certain
number of insert flaps and insert recesses are required. In
the case of smaller transport packages, usually four insert
flaps and insert recesses are provided, whereby two are
each time facing each other. It has appeared that for
forming the connection between hood and tray, those
configurations are advantageous in which two trapezoidal
cut-outs are provided for each connection, resulting in two
trapezoidal insert flaps linked with each side to the side
~; wall in such a way that the linked side is at 90 to the
bottom plate of the tray. The side of the trape~oidal
insert flaps facing the linked side, is formed with both
trapezoidal flaps by a single incisionO The advantage of
this design is that, for one connecting unit, two sides are
available by which the insert flaps are linked to the side
wall. This results in a more stable mechanical connection
between hood and tray.
The height of the side walls of tray and hood is designed
dependent upon the height of the containers of circular
cross section contained in the transport package. In a
preferred embodiment, the transport package exhibits a
hood, the side walls of which are twice the height of the
side walls of the tray. It is particularly preferable that
:, ~ .
2~7~
Q 7141 (R)
the height of the side walls of the tray be at most a
quarter of the height of the hood.
A transport package usually consists of corrugated paper or
cardboard. It is, however, also quite possihle to
manufacture the package from several plastic sheets having
the required rigidity and firmness.
The outside dimension of a full tran6port package can be
lowered through the transport package referred to above.
The outside dimension of the transport package, when the
containers are juxtaposed in rows in the transport package,
then corresponds at least with the sum of the outer
diameters of the containers plus the thickness of the
packaging material. According to the invention, the
external dimensions of the transport package can now be
reduced by at least two layers of the packaging material.
As a result of the recesses provided in the side walls of
the hood, the containers of circular cross section, at the
place of the largest expansion, directly abut against the
side walls of the tray since, owing to the recess, the hood
has no material in the places where the containers of
circular cross section abut against the side wall of the
tray. The flaps between the recesses of the side walls of
the hood can, however, be introduced inside the side walls
of the tray without causing the side. wall of the tray to
bulge. Accordingly, as a result of the reduction of the
outside dimensions of the transport package, space can be
saved, enabling optimum utilization of space in the
transport package. This benefit will become especially
conspicuous when several of these transport packages are
placed side by side in a larger unit since, as a result,
projections are avoided. Accordingly, more container units
per pallet can be introduced without resulting in
projections from the transport package that can no more be
tolerated during transport.

6 Q 7141 (R)
As the recesses in the side w~lls of the hood can be
exactly adapted to the containers to be packaged, enhanced
stability of the whole transport package can be reached
since the edges of the flaps formed between the recesses of
the hood are direcly resting on the containers of circular
cross section placed in the transport package. This
increases the stability of the transport package, thus
protecting it from toppling over.
Furthermore, savings in material can be obkained by an
adequate arrangement of the blank of the hood. This can,
for instance, be reached by placing, in the case of the
blank for the hoods, two juxtaposed blanks in such a way
~ that flaps and recesses interlock alternately so that the
; 15 recess of one hood simultaneously forms the flap for the
hood arranged next to it. This saving in material is,
- however, also advantageous when, after delivery of the
goods, the transport package is removed and has to be
disposed of.
` A further advantage of the transport package according to
the invention resides in that, even without the transport
package having to be removed, it can be seen from the
outside which goods are contained in the transport package.
As a result, transport personnel can discern without
difficulty what is contained in the transport package and
confusions can be avoided to a great extent.
Preferred embodiments of the present invention are
illustrated by the following drawings, in which :
Fig. 1 sbows a blank for a tray with unfolded side
walls. Two short side walls (11), which are arranged facing
each other, are linked to the bottom plate (10). The longer
side walls (123 are linked to the two other side walls.
These~ side walls have insert flaps (13), formed by

recesses, linked by one side with the side wall (12).
Fig. 2 shows a hood having a covering plate (25) and
two side walls (2~), which are each time linked by a common
side. on the edges facing away from the bottom plate, the
side walls (24) exhibit flaps (21) which are separated by
recesses (22). In some of the flaps, insert recesses (23)
are provided into which - in assembled state - the insert
flaps (13) of the tray are introduced.
Fig. 3 shows another embodiment of a hood havincJ two
short side walls (26~ facing each other. Also these side
;~ walls have a flap (27) placed between two recesses provided
next thereto.
~` 15
Fig. 4 shows a further embodiment o~ the hood, ln
which the recesses ~28) are provided such that they do not
i~ extend as far as the lower edge of the side face. This
embodiment is especially suitable for those containers of
circular cross section that are approximately spherical.
When, namely, the ~ircular cross section of the container
near the bottom is smaller than the maximum diameter, the
side wall of the hood can be passed between container and
side wall of the tray without the side wall of the hood
resulting in a larger outside diameter of the transport
package.
Fig. 5 gives a cross-sectional view of the transport
paakage according to the invention, in which the containers
(30) contained in the transport package are standing on the
bottom plate (10) of the tray. The side wall o~ the tray
~12), in the lower area, immediately joins the side wall of
the container. The covering plate (25) of the hood rests on
the upper part of the container, and the side wall of the
hood (24) extends as far as the collar of the container
: (30). In the gap between the individual containers (30),

the side wall of the hood touches the bottom plate (103 of
the tray.
