Abstract

ABSTRACT

A folding box for the accommodation of a roll of wound plastic bags is provided with a closing flap which completely overlaps the front wall of the box. In the lower part a closing flap is glued firmly to the front wall. In the central part the closing flap is separable by means of a tear-off strip, so that the area connected to the lower part of the front wall may be separated from the upper part, the upper part of the closing flap remaining attached to the cover of the box. The upper part of the closing flap may be inserted between two retaining flaps on the front wall. The area remaining after the tear-off strip has been removed forms an aperture for the withdrawal of plastic bags, a tear-off flap of approximately trapezoidal cross-section being for-med in the vertical area. Since the front wall is connected to the lower part of the closing flap, not only tear-off flap but also the entire lower limiting edge of the withdrawal aperture has two layers and is therefore reinforced. Such re-inforcement is not found in folding boxes presently used for similar purposes.

Description

The present invention relates to a folding box for the accommodation of a roll of wound plastic bags, the box having a tear-off strip e~posing a withdrawal aperture pro-vided in one wall of the folding box, -the said withdrawal aperture being provided in the central area of its lower limiting edge, with an approximately trapezoidal tear-off flap for the plastic bags, the latter being perforated at right angles to the direction in which they unwind and being provided with a central capture-slot.

In known folding boxes of the type in question, the tear-off strip is located on the rear wall, i.e., on the wall to which the cover is hinged by a closing flap. Although the design of such a folding box has been found satisfactory in principle, the disadvantage is that the tear-off flap is re-latively weak, since it is made out of the material of the rear wall only. Another disadvantage of known folding boxes o~ this kind is that the boxes can be opened without damaging the tear-off flap. For this reason it has been necessary to provide known folding boxes of the type in question with ad-ditional wrapping, so that unauthorized withdrawal of the bagsis no longer possible, or so that such unauthorized withdrawal is immediately detectable.

It is the purpose of the present invention to design a folding box oE the type in question in such a manner that rein-~5 forcement of the tear-off flap is provided and, at the same time, that the box can be opened only after the tear-off strip has been removed.

In the case of the folding box of the present invention, this purpose is achieved by the following characteristics:

a) the tear-off strip is a part of the closing flap;
b) the closing flap overlaps the front wall as far as ~3~

the bottom and is glued thereto in the area between the bottom and the tear-off strip;
c) the section of the front wall located above the lower edge of the withdrawal apexture i5 connected to the re-maining material of the front wall only by a weakened foldingedge and is adapte~ to fold into the interior of the folding box;
d) the folding part of the front wall is shorter than the overall length of the front wall, and a retaining flap is thereore formed at each end for the upper part of the closing flap remaining after the tear-off strip has been separated.

A folding box design of this type provides a series of technical advantages. In the first place, shifting the tear-off strip into the closing-flap area means that the folding box can be opened only after the tear-off strip has been re-moved. Unauthorized opening of the box is therefore immedia-tely recognizable.

Uniting the lower part of the closing flap with the front wall substantially reinforces the flap for tearing off individual plastic bags, but this requires no additional ma-terial for the production of the folding box.

The inwardly folding part of the front wall provides additional reinforcement of the lower edge of the withdrawal aperture. Furthermore, the inwardly folded part of the front ~5 wall provides good guidance for the roll of bags located with-in the folding box.

The lateral retaining flaps for the remaining upper part of the closing flap make it possible for this remaining upper part to be inserted into the interior of the box, so that the cover, with the adjoining upper part of the said ~3~

closing flap, cannot slip out inadvertently. This greatly simplifies the handling of the folding box while the plastic bags are being removed.

Further characteristics of the invention can be ascer-tained from the following description and the appended claims taken in conjunction with the drawings. An embodiment of the invention is explained hereinafter in greater detail, taken with the drawings attached hereto, wherein:
FIG. 1 shows a blank for a folding box embodying the invention;
FIG. 2 is a perspective view of a folding box made from a blank according to FIG. 1, in the closed condition;
FIG. 3 is a perspective view of the open folding box;
FIG. 4 is a perspective view of the open box with a part of the front wall folded into the interior;
FIG. 5 is a perspective view of the folding box ready for use;
FIG. 6 is a perspective view of the folding box, showing a plastic bag ready to be torn off;
FIG. 7 is a cross-section along the line 7-7 oE FIG. 6.

The invention consists in a folding box for the accom-
2~ modation of a roll of wound plastic bags, a tear-off strip, exposing a withdrawal aperture for the removal of plastic bags, said strip being located in one wall of the folding box, and the said withdrawal aperture comprising, in the central area of its lower limiting edge, an approximately trapezoidal tear-off flap for the separation of the plastic bags, the bags beingperforated at right angles to the direction in which they un-wind and being provided with a central capture-slot, charact~r-ized by the following features:

_ 4 _ ~ ~3~6~

a) the tear-off strip being a part of the closing flap;
b) the closing flap overlapping the front wall of the box as far as the bottom thereof and being glued to the front wall in the area between the said bottom and the said tear-off strip;
c) the section of the front wall located above the lower edge of the withdrawal aperture being connected solely by a weakened folding edge defining a folding part of the front wall, to the rest of the material of the front wall of the box and being adapted to fold into the interior of the folding box;
d) the folding part of the front wall being shorter than the overall length of the said front wall and a retaining flap being thereby formed at each end for the upper part of the closing flap remaining after the tear-off strip has been separated.

The blank for a folding box, shown in FIG. 1, is made in one piece and comprises a front wall 1, a bottom 2, a cover 4 with a closing flap 5 hinged thereto, lateral waIls 6 and adhesive flaps 7. The closing flap S is provided with a tear-off strip 8 having an approximatel~ trape~oidal shape in thecentral area.

With the folding box in the finished condition, the closing flap 5 completely overlaps the front wall 1 to which it is glued in the area below a tear~off strip 8. The front ~5 wall 1 has an upper part 9 which is connected to the remaining material thereof by a weakened folding edye 10 running parallel to the lower edge of the tear-off strip 8.

The overall length of the upper part 9 of the front wall 1 is shorter than the overall length of the front wall 1, leaving a retaining flap 11 at each end. After the tear-off strip 8 has been removed, the cover 4 and the upper part of the closing flap 5 can be raised, so that the interior of the - folding box is accessible.

- 5 ~ ~ ~3~

As indicated, the folding box is designed to accommo-date plastic bags wound into a roll, as shown in dotted lines in FIG. 4.

After the folding box has been opened, the roll is taken out and the upper part 9 of the front wall 1 is folded into the interior of the box. The roll is now replaced in the box and the cover 4 may be closed again. The said cover is secured in the closed position in that the remainder of the closing flap 5, attached to the cover 4, is insert~d behind the front wall 1, as shown quite clearly in FIGS. 5 and 6.

After the upper part 9 of the front wall 1 has been olded into the interior of the folding box, a withdrawal ap-erture 12 is formed, the contour of which corresponds to the tear-off strip 8. Formed in the central part of the withdraw-al aperture 12 is a tear-off flap 13 which has two layers, since the front wall 1 and the closing flap 5 are glued to-gether in this area.

As may be seen particularly clearly in FIG. 6, plastic bags 14, wound into a roll, are provided, at right angles tQ
the direction in which they unwind, with a per~oration 15 and a central capture-slot 16 which places itself over the tear-off flap 13 when one of the bags 1~ is pulled from the roll and is to be taken from the folding box. In this secured posi-tion, it is a simple matter to tear the first bag from the roll along the perforations 15.

As shown clearly in FIG. 7, the upper part 9, folded into the interior of the box, of the ~ront wall 1 provides good guidance for the roll from which the plastic bags 14 are to be taken.

As also shown very clearly in FIG. 7, the upper part 9 of the front wall 1, which is folded into the interior of the - 6 - ~ ~3~6~

folding box, is larger than the remaining lower part of the front wall l, so that the upper part 9, folded into the in-terior of the folding box of the front wall l is supported in an oblique position upon the bottom 2.

It is desirable for the folding edge lO, along which the upper part 9 of the front wall 1 can be folded, to be ar-ranged somewhat higher than the lower edge of the tear-off strip 8, since this makes it easier to thread the tear-off flap 13 into the capture-slots 16 in the plastic bags 14.
