Packaging container

In particular The invention relates to a packaging container made of cardboard, with side walls that are between the top and the bottom Run to the end of the container.

Cardboard packaging containers provide a convenient form of packaging for a variety of goods in many ways. Because such However, packaging containers are generally rigid and self-supporting, that of a packaging container occupied storage space is normally not reduced when the contents of the container have been removed, as in the case of i'exiblrn packaging containers, such as bags, is possible. This can be disadvantageous in cases where the storage space is limited, for example in storage rooms for food in the household, such as freezer, refrigerator, pantry or the like.

The invention is based on the object of a packaging container of the type mentioned in such a way that it can be reduced in size according to the removal of the container contents.

709815/0341

This object is achieved according to the invention in that at least one weakening line is provided in the side walls which runs in the area between the upper and lower container ends over the circumference of the side walls, and that a upper container section is separable along the weakening line from a lower container section.

As a result of the design according to the invention, the upper container section be separated to reduce the storage space if the container content is below the weakening line has been removed. The separated, upper container section is usually waxed away. However, it can of course can also be reused as a container or packaging if necessary.

The packaging container is preferably at the top and / or bottom The end is provided with a closure which has a push-in flap or the like. The packaging container can preferably also immediately below the weakening line, for example by the arrangement of fold lines, designed 3ein that further closures, such as tuck-in flaps or the like., To Closing the lower container portion are formed after severing the upper container portion.

The line of weakness running along the circumference can Have perforations or the like. If necessary, several such weakening lines can be arranged at a distance from one another so that successive upper container sections can be separated.

The packaging container can be folded in a conventional manner and glued cardboard. It is also possible to use any other suitable material in the packaging container any suitable way to form.

Further features of the invention emerge from the description, the claims and the drawings.

The invention is illustrated by means of two in the drawings Embodiments explained in more detail. Show it:

Fig. 1 is a perspective view of a first embodiment of a box according to the invention,

2 shows a perspective and enlarged representation lower part of the box according to FIG. 1, the upper part of which has been removed, with closing flaps of the lower Part are arranged in a partially closed position,

3 shows a second embodiment in a representation according to FIG. 1 a box according to the invention, ^ retarding

Fig. 4a and 4b, the upper and lower portions of the carton according to dlej separated FIG. 3.

The box shown in Fig. 1 can be used for the packaging of food or for other suitable purposes will. It has an elongated box body 1 with a square or rectangular cross section, which consists of There is folded and glued cardboard and conventional closing flaps 2 are provided at its upper and lower ends are. The bottom closing flaps 2 are shown in their closed position, in which they close the lower end of the box, while the upper closing flaps 2 are shown in their open position, in which the interior of the box for Filling or removing the box contents is accessible. '.

The box can be folded flat in a conventional manner by folding around the upwardly extending edges when the lower and upper closing flaps are not tucked in. The erected box is relatively stiff and
self-supporting.

The side walls of the box have two perforation lines 3 which are spaced apart from one another and from the upper and lower ends and run over the entire circumference. The distance between the two perforation lines 3 is smaller
as the distance of the lower line 3 from the bottom of the box
and greater than the distance of the top line 3 from the top of the box. The box is divided in this way by the two lines into three sections 4, 5, 6, their
Size decreases from the bottom up.

At a small distance below each perforation line 3 is a fold line 7 extending over the entire circumference of the box is provided. Above this line 7 are formed: ei * i aubgeschxiitJenor Schlitr: 8 in the back of the box (Fig. 2) and an arrangement of fold lines 9, 10 on the side walls and the front wall of the box. Every side fold line 9 is provided in the middle of the box.

If the contents of the container are below the length of the circumference extending fold line 7 has been removed below the upper perforation line 3, the upper box section 4 can be removed by tearing along the perforation line 3. The remaining . lower box sections 5 and 6 can then be closed in the manner described below, see above that the storage room can be preserved.

709815/0341

After removing the upper box section 4, the the upper peripheral areas of the remaining part of the box lengthways of the fold lines 7, 9, 10 are folded, as shown in FIG. 2 is shown. The side panels are inwardly over the sides of the front panel to form a substantially triangular flap 11 folded. The back is folded over the filling opening of the rest of the box part 4, 5. The tab 11 can then be folded over the back and inserted its free end into the slot 8 to close the box will.

Then, if necessary, the next box section 5 can be removed so that only the bottom section 6 remains. The upper peripheral area of this bottom section 6 can then folded in the manner described.

In another embodiment, instead of the conventional one Closing tabs x 2 at the top and / or bottom of the box, another closure can be used, such as the to:.! Exchanges the upper ends of the lower box sections 5 * 6 shutter used.

The embodiment shown in Fig. 3 is particularly for Not whipped cream, butter and cheese are suitable. It can of course also be used for other purposes.

The box shown in Fig. 3 is similar like the box according to FIG. 1 and has an elongated box body with a square cross-section made of folded and glued cardboard with conventional tuck-in flaps 12 at the top and bottom for closing the box 1st. The box body is also divided into three box sections by circumferential perforation lines 16 13, 14, 15 divided, the size of which decreases from bottom to top.

709815/0341

In contrast to the embodiment according to FIG. 1, the perforation lines 16 do not lie in one plane, but are arranged offset on the front of the box in the direction of the upper end of the box and form upwardly directed flap parts 17, 18. In the flap parts 17, 18 there are fold lines 19 intended. After the upper box section 15 has been severed (FIG. A), the upright flap part 18 remains at the upper end of the remaining bottom sections 13, 1 ^ of the box. This flap part 18 can be folded over and inserted into the box to close the upper end of the base parts 13, I ^{1 *.} The following box section 1H can then be removed, the bottom section 13 with its upright tuck-in flap 17 remaining.
