Description

Folding box with hinged lid Folding boxes with retracted side walls are known as hollow bodies or in the form of flat blanks. That's how it is described a box with two special end walls against shoulders of one And are limited in their outward movements while they are supported from the inside by the contents of the box. There is also a box body with retracted side walls through a deformable to a prismatic tube Known blank and two cardboard covers glued into the ends. After all, supposed to a box body with retracted side walls made from a single piece of cardboard material exist, but which does not have a cavity that is closed in itself to accommodate the content forms and as a result of the unfavorable blank shape, a less advantageous material utilization allowed.

In contrast, the invention is intended to provide a folding box with retracted Sidewalls are created using a rectangular piece of cardboard so formed is that with almost complete utilization of its base it is slightly different from the flat lying State can be shaped into a packaging that is in terms of material consumption and production is particularly inexpensive, due to the on the outer edges provided stiffening even when using relatively weak cardboard material has a high stability and finally a prepared to receive the content, forms a self-contained cavity and, moreover, in the closed state only printable cardboard surfaces and thus an attractive appearance.

The training necessary for the folding box in the context of the invention The piece of cardboard and preparation of the cut is illustrated in the drawings and described in detail below.

The drawing also shows examples of the application according to the invention An object, namely in Fig. 1 a flat cardboard blank, Fig. 2 the same blank glued, Fig. 3 the folding box created from it in the open State, FIG. 4 the box in the closed state and cross-section, FIG. 5 and 6 additional inlays and their task to secure the front corner connection the folding box and FIG. 7 other exemplary embodiments of a folding box in conical shape.

The numbers from 1 to 29, furthermore 37 and 38 designate parts of the cardboard blank for the folding box, the numbers over 100 slots or incisions and the numbers over 200 bending folds.

It shows: the surfaces 10 to 14 of the blank that will be later Center piece forming the box jacket, which is secured by bending folds 211, 212, 213 and 214 in the front wall 10, the bottom surface 11, the rear wall 12, the top surface 13 and the closure flap 14 is divided. Lined up on both sides of this middle piece and made articulated by bending folds 215 and 216, the adhesive strips 15 and 16 and further those also delimited from the adhesive strips by bending folds 217 and 218 Side walls 17 and 18 or

Sealing ribs 19 and 20.

The adhesive strips 15, 16 are on the bending folds 215, 216 around 1800 bent back and fixed to the middle piece 10 to 13 by gluing or stapling tied together. If the aforementioned parts 17 to 20 on the bending folds 217, 218 of If the adhesive strips are bent vertically upwards, this creates indented side walls or sealing ribs, which are later parallel to the final shaping of the folding box to the outer edges, but slightly offset inwards. Through this essential Features of the invention are achieved. that first after forming the blank for Box whose side edges are specially stiffened all around. Second occurs as a result of the pulling in of the side walls or the sealing ribs behind the reinforced ones Outer edges relieve these drawn-in parts because they have no pressure or are more exposed to external impact. Third, it affects the stiffening the outer edges by means of the adhesive strips in connection with the drawn-in side walls and sealing ribs not only stabilize the box structure at the edges off, but also forces the mostly larger base or lid surfaces into their prescribed location to lie flat. so that even with large-format boxes this kind of distortion, which is otherwise often observed and annoying or Arching up of such box surfaces is avoided.

The one for holding the carton together and for forming a self-contained cavity for receiving the box contents necessary connection between the erected side walls and the adjacent front or rear wall and the side walls below are made in the usual way for folding boxes, of which the embodiment shows two possibilities: the connection of one End of the side walls 17, 18 with the front wall 10 by cone-like deformable Folded corners, also the connection of the side walls with each other on their other End through connecting webs 23, 24, which cut the side walls 17> 18, are delimited and hinged by bending folds 223, 224. The sealing ribs 19, 20 20 are left out of these connecting webs.

The connecting webs 23, 24 can after vertical alignment of the Side walls 17, 18 angled at 90 ° to these and by means of incisions provided for this purpose 123, 124 are hooked into one another (see FIGS. 3 and 5). You are still free End of the connecting webs support flaps 25, 26 provided, which by means of a bending fold 225, 226 are angled and for better stabilization against the back the side walls 17, 18 can create (see. Fig. 5).

Both the front wall 10 and the two retracted side walls 17, 18 and one of the connecting webs 23 can be delimited by bending folds 227 Cardboard strips 27 be cut, the flanged edges angled by 900 known result.

The invention provides for securing the fold corners 21, 22 against a Re-opening a formation of the carton blank in such a way that the on the side walls 17, 18 located flanged edges 27 to fold feet 28 with support surfaces 29 can be extended. By means of these downwardly angled folding feet the fold corners 21, 22 pressed against the back of the side walls 17, 18, wherein the folding feet themselves with an additional insert strip ES with a dovetail shape cut ends are held in place (see Fig. 5).

There is another possibility of securing the fold corners 21, 22 in the attachment of a so-called overhang flap 37 of known type with articulated Skirting board 38 on the front wall 10 of the folding box. This overhang flap is on a folding fold 237 folded inward over the fold corners so that their skirting board 38 rests on the floor 11. To hold such a cover flap in your The invention provides an additional insert strip E, the middle part of which E.1I sits on the baseboard 38, while its two hinged side flaps EL against the rear of the side walls 17, 18 or between these and the support flaps 25, 26 of the connecting webs (see Fig. 6).

The strips EB can, depending on the design of the front wall 16, as flanged edges or serve as baseboards.

The invention also relates to folding boxes with drawn-in Sidewalls in a conical shape and with a trapezoidal or triangular cross-section as well as the option of pulling in a cord or pushing in a handle to design the folding box as a carrying container.

PATENT CLAIM 1. Folding box with a hinged lid with only two opposite side walls arranged perpendicular to the cover are drawn in to the other box walls are arranged, with bevelled side walls of these Strips by gluing or the like to the bottom, the front and the rear wall of the box are finally connected to their leading edges, characterized in that all box parts are formed from a single blank, the lid (13) also have drawn-in adhesive strips (15) on two opposite sides can, which end in bent and free-standing sealing ribs (19, 20j, which lie in planes parallel to the side walls (17, 18) of the box, and that the side walls (17, 18) hinged to the front wall (10) at their other ends are also connected by interlocked webs (23, 24), whereby the to the back wall of the box (12) used when opening the lid (13) can fall back.
