CASE FOR CASING PACKS OR CARTONS OR TrIE LIKE
The invention relates to a case for casing packs or
cartons or the like of goods, herein referred to as a collecting
case.
Cases serve to protect and retain packs or cartons or
the like, e.g. of cans, boxes or the like, in transportation.
It has proved economical, more particularly in self-service
establishments, for the goods to be sold directly from the ease
in which they are supplied - i.e., for the goods to be displayed
in the case. So that customers can see the goods and more part-
icularly have access to them, the case must of course be opened.The use of cases suitable for use as cut case displays in the
manner just described leads to from 300 to 400 percent improve-
ments in efficiency in shelf filling in self-service stores.
Large structures using cases also save considerable time as
compared with conventional shelving structures and if cases and
cut case displays are used together the resulting structures can
be much more stahle than unsecured stacks of individual packs.
The de-stackingof unsold goods and their return to storage are
quicker and cheaper too.
Conventional cases normally consist of rectangular
cartons which are closed on six sides and which can be opened
with a case opener or by
- 1 -

tear~ng along marked perforations or by tearing off tear-off tab~ or
strips into the required cut case display. The individual packs on
the display shelves are prevented from falling over or shifting by
residues of the carton side walls. Unfortunat~ly, the perforations of
the known cases of this kind often fail to tear satisfactorily~ and 80
a case opener is used to open up the carton more rapdily, but with the
risk that the goods in the case - i.e. the individual packs - often
suffer damage. Tear-off strips are easier to handle but costly to make
and fit and are therefore not widely used. Another disadvantage of the
known cases is that the conventional practice of closing a carton on
8iX sides by tabs or flaps, although providing non-twisting cases which
can be transported satisfactorily, entail~ relatively high costs for
paokaging material. The cartons themselves becomo ver~ buIky waste
material when they are opened or cut at the place of use since the flat
form of securing makes them difficult to fold. Another d~sadvantage
is that since the cartons of tho ~nown cut ca~e displays usually engQge
~ery tight b around the goods, it is difficult for clients to remove
the first packs from the cut case displays.
It i5 there~ore the object of the invention to provide a method
and a ca~e of the kind hereinbefore described which can provide
cheaper packing than with the known cartons closed on 8iX sides, speed
up handling and conYert to waste which can be re~oved readily while al6o
ensuring reliable transportation, ease of handling and little risk of
the goods or intivitual packs falling over during transportation or
during stacking in self-service shops or the like.

In accordance with the invention there is provided a
collecting case adapted for use as a cut case display for a
carton of goods having a vertical peripheral surface, said case
comprising a substantially closed circumferential wall which is
substantially vertical and is adapted to completely surround
said peripheral surface of the carton of goods, said wall being
open at its top and at its bottom, and a tray-like base which is
a separate component from said circumferential wall, said case
base including a bottom and a peripheral edge, said base being
made of a corrugated material, said circumferential wall being
made of a corrugated material which stiffens said wall in the
vertical direction, said circumferential wall and said case
having a substantially rectangular shape in the horizontal
plane, said circumferential wall over substantially its entire
height being adapted to engage -tightly with the vertical
peripheral surface of said case, and said peripheral edge of
said case base tightly engaging the lower edge portion of said
circumferential wall, said peripheral edge of the case base
having a height of approximately 1/3 to 1/5 of the height of
said circumferential wall, the relative dimensions of said
circumferential wall and said peripheral edge being related to
each other and ~o said peripheral surface of the carton such
that a close friction tight connection of such a strength is
achieved that upon the action of a substantially horizontal
65~6
pressure applied on the circumferential wall, the carton may be
transported with the case base, and upon the action of a
substantially vertical pulling force onto said circumferential
wall, said wall may be withdrawn from said case base, leaving a
space between said peripheral edge and said carton and thereby
facilitating removal of goods from said case base.
Since the case in accordance with the invention has
only five wall parts, there is a considerable saving of material
as compared with conventional cases. For example, flap-secured
cartons cost up to 4C% more for packaging material than the case
in accordance with the invention because so much material is
wasted in the cutting of the blanks for the flaps. The srnooth
tray-like base of the base member of the case facilitates
transportation since there are no projection flaps and the
sharp-cut vertical peripheral wall improves the stability of
stacking in transportation as compared with ordinary cartons.
Also the peripheral wall can be folded readily and therefore
converts at place of use into waste taking up little space and
entailing little cost once the peripheral wall has been severed
from the tray-like base.
One considerable advantage is that because of the tight
press fit of the peripheral wall on the one hand and of the
peripheral edge of the base member on the other hand, the case
according to the invention is easy to handle and stack while
substantially horizontal pressures act on the peripheral wall,

whereas at the place of use the peripheral wall can be pulled
off readily by vertical pulls, whereafter the goods - i.e., the
individual pack - in the tray-like base members can be displayed
without any risk of shifting laterally.
Preferably, said circumferential wall is provided with
gripping means rendering possible a substantially vertical
pulling force, and also preferably said gripping means may
comprise flaps cut into said circumferential wall.

case of Fig. 4;
Fig. ~ ~hows a variant of a peripheral wall of the case in
accordance with the invention, and
Fig. 7 shows a carton of goods on the tray-like base member of the
ciase according to the invention in the sale display positio~.
As the drawings show, in the embodiment shown the case in accordance
with the invention comprises a per~heral wall 12 engaging closely and
tightly around a carton or pack or the like 10 of good~ to be ancased~
the case also compr~ing a box-lid-like or tray-like base member 20 having
a baso 22 and, rigidly secured thereto, a peripheril edge 24. The
peripheral wall 12 extendei in c~ose frictional engagement around the
carton or pack 10 and the poripheri~l ed8e 24 of the ba6e member 20 also
extends in close ~rictional engagement around the bottom edge portion
of the wall 12.
To carry the method according to the in~ention into effect~ the
carton 10~ consistiug o~ a number o~ indiYidual pack6i~ is first compressed
into a tight pack~ then has the peripheral wall 12 placed around it,
care bein6 take~ to ensure that the wall 12 extends tightly and closely
around the ca~Dn 10 - i.e.9 is in ~rictional engagement therewith~
After the ca~e haei been brought into this condition9 which can be
.
~1465~6
gathered more particularly from Fig. 2, the tray-like base member 20
is fitted by the peripheral edge 24 being pushed up from below on to
the peripheral w~ll 12, the elemen~ 24 and ~ entering into a firm
~rictiona~ engagement with one another. The method can be carried out
rapidly and without complicated sticking operations such as are used in
the conv~ntional method~. The resulting complete case can be handled
readily - i.e., by the application either of vert~cal forces to the
under~ide of the base member 20 in the direction indicated by an arrow
14 at the bottom of Fig. 4 or of horizontal pressures to the peripheral
wall 12, as indicated by the arrows 14 on the right and left of Fig~ 4.
The complete system i8 held together by friction between the carton lo
and the wall 12~ on the one hand, and between the wall 12 and the
edge 24, on the other hand9 so that the case can be transported
~ati~factorily. Upon arrival Or the case at the place of use, ~ub-
stantially vertical pulls are applied to the wall lZ in the direction
indicated by arrows 16 in Fig~ 4 80 that the wal1 12 can be pulled out
away from edge 24 of member 20 and remov~d. To facilitate the applicatio~ ;
of vertical pulls to the wall 12, flaps or the like 18 can9 with
adv~ntage~ be provided on the wall 12 in the manner visible ~n Fig.
to facilitate removal of the wall l~.
After the wall 12 has been pulled off, the individual packs -
i.e~ the goods - remain beh1nd on the tray-like ba~e member 20 and can
be displayed as they are. Information about pricing amd ~3kers c~n be
provided cheaply amd simply on the peripheral edge 24 of the member 20,
something which may be a useful selling feature- Once the tight-fitting
65V~
wall 12 has been removed, the individual packs stand loosely
on the member 20 at a distance from its edge 24 corresponding
to the thickness of the wall 12; clients can therefore remove
the first individual packs readily, yet the individual packs
are secured against falling over or shifting or the like.
