Description

Folding box.

The invention relates to a folding box that It can be used for accommodation and transportation of objects.

The boxes have been known for a long time foldable They are made of cardboard by punching, folding and glued. After punching and partly also after making, the folding boxes can be transported in the still folded state from the manufacturing place of the folding box to the places where They will fill with objects. The folding boxes serve to gather these objects forming sales units, transport objects and accommodate them also before use. In many cases, the boxes Folds of this type are filled again after being emptied by complete or used for other purposes.

Usually, folding boxes have a fixed size, adapted to the size of the objects to be housed in the same.

Normally, objects are small in relationship with the size of the folding boxes.

However, there are cases in which relatively long objects must be packed. These long objects, for example screws, are produced with different lengths. It is possible to have your own box manufactured for each different size, store it and use it. However, when it comes to relatively small series, this implies a higher cost.
high.

The folding boxes that are known are formed by an open envelope on the front side and a drawer insertable in it. There are folding boxes in which the wrapper has a hole like a window on its upper side. The drawers in part are also closed at the top or They can also be open at the top. In these boxes foldable, the drawer is inserted back into the box after removed an object from the box. In the closed state, the envelope it is inserted in such a way in the envelope that its front side Finish flush with the front side of the wrap.

Unlike this type of folding boxes, the invention proposes that the drawer can present several positions, of which at least one position is such that it is not completely inserted in the envelope. These positions are interlocked by interlocking devices, so that the drawer remains in a fixed relation to the envelope. For withdrawal, the drawer can be opened on its front side, for example with the help of a top. The box is converted in this way through the various positions in a box with different sizes. Therefore, for the storage is enough to have stored only one type of folding box for objects of different sizes or for quantities other than objects

A multi-part package is already known, formed by two boxes insertable one in another in the direction longitudinal; see document DE 9 410 606 U. The position relative of the insertable boxes in one another as a telescope It can be adjusted in several positions.

The invention aims to create a enhanced possibility to be sufficient with a single size of box for objects of different lengths and / or for different quantities of objects

To achieve this objective, the invention proposes a folding box with the characteristics indicated in the claim 1. The dependent claims refer to variants of the invention.

In a variant of the invention it may be provided that after the cover of the folding box a separation wall formed by a tongue, which extends preferably parallel to the lid in the closed state of the same. In this way a smaller compartment is formed in the area on the front side of the folding box, where they can staying objects other than the rest of the box, for example accessories, operating instructions or similar material.

The opening of the folding box drawer can be achieved, for example, because the front side of the drawer is formed completely or partially by a lid that is foldable. Is especially recommended that the lid is articulated in a ridge of the drawer, which during the use of the folding boxes is oriented usually on the lower side.

Normal folding boxes are shaped like a parallelepiped. However, the invention is not limited to folding boxes in the shape of a parallelepiped but can be used in all forms of folding boxes, in which it is possible to remove or insert a drawer more or less, that is, usually in boxes binoculars

In order to use the folding box proposed by the invention in the most versatile way possible, according to the invention in a variant it may be provided that there is a position of the interlocking device in which the drawer is inserted to such an extent in the envelope that its front side extends to flush with the front side of the wrap. Naturally it is it is recommended that the length of the drawer measured in the direction of insertion is not greater than the length of the envelope measured in the same direction.

In another variant of the invention it may be provided that the interlocking device has a plurality  of positions of an insertion depth different from drawer.

The interlocking device features protrusions made in the drawer and corresponding holes punched in the wrap.

The protrusions of the drawer are obtained by punching and bending of the punched part. Holes Correspondents are also made by punching.

It is especially recommended that the outgoing of the drawer are arranged in the edge area of the drawer, preferably in the area of the upper longitudinal edges. Since the projections are obtained by punching by folding then the cardboard cutout, these protrusions simply they remain in an upright position, so that they arrive so Virtually automatic to the correct position.

The projections are made in such a way that facilitate the insertion of the drawer in the wrapper while make it difficult to withdraw. This is done in an asymmetric way. of the outgoing. Since the length of the folding boxes is fits objects, the length of the folding boxes should no longer be modified after the adaptation made once. For this reason it is It is advisable to facilitate insertion and then perform a fixation to prevent withdrawal.

According to the invention, between the envelope and the drawer can be made a tight fit, which can also serve to support the interlocking device.

The separation wall mentioned at the beginning it can be formed, for example, by an articulated tongue in the upper side of the drawer, that is, on the opposite side of the lid joint.

The tongue of the separation wall can present lateral projections, with which it can be inserted in laterally folded tabs of the drawer to fix them.

Other properties, characteristics and advantages of the invention follows from the claims, whose literal text It is made with reference to the content of this description, the description set forth below in a form of preferable embodiment of the invention as well as with the help of He drew. Here they show:

The folding box represented in one way simplified in Figure 1 comprises a wrapper 1, which is Made of cardboard. It comprises two side walls 2 thereof size, a bottom 3 that cannot be seen in Figure 1, one side upper 4 and a rear wall, which is assembled by insertion or otherwise. The envelope 1 can be made of a cardboard cutout The envelope 1 has the shape of a parallelepiped.

In drawer 1 a drawer 5 is inserted, which It also has a parallelepiped shape. Drawer 5 comprises two identical side walls 6, a top side 7 and a bottom 8 that cannot be seen in Figure 1. On its front side, drawer 5 comprises a front wall 9 that can be folded down around the edge 10 which in Figure 1 is the lower edge. For securing the lid 9 in the closed state a tab 11, which is articulated on the upper side 7 of the drawer 5. This is known per se.

The drawer is sized so that its outer shape corresponds roughly to the inner shape of the envelope 1, so that it can be inserted into the envelope 1 with tight fit.

The upper side 4 of the envelope 1 comprises holes 13 in the form of grooves extending parallel to the upper longitudinal edges 12, whose width corresponds approximately to the thickness of the cardboard material used in the drawer 5. Slots 13 exist on the two longitudinal sides of the envelope 1 and in the example represented in the two edges Longitudinals in the same position measured from the front side of the envelope 1. The grooves 13 are arranged so equidistant.

In the grooves 13 mesh projections 14 arranged on the upper side 7 of the drawer 5. These projections are only made in the rear area of the drawer 5. The drawer can have several projections 14 arranged one after the other, whose mutual distance corresponds to the distance between the grooves 13. The length of the projections 14 measured in the longitudinal direction of the drawer 5 corresponds to the length of the grooves 13. The engagement of a projection in a groove 13 is shown in Figure 2. The projections 14, which are made by punching, they protrude from the upper side 7 of the drawer upwards, their outer side extending flush with the side walls 6. The flank 15 of the projections 14, which is oriented backwards, that is, towards the rear wall of the envelope 1 , extends slightly upward, while the forward-facing front side 16 extends approximately at right angles to the upper edge of the walls sides 6. The height of the projections 14 corresponds approximately to the thickness of the cardboard material of the envelope 1. As can be seen in Figure 2, by moving the projections 14 in the grooves 13 a displacement of the drawer 5 towards the left in Figure 2, while it is permissible to continue moving it to the right in Figure 2. Thanks to the cooperation of the projections 14 with the plurality of grooves 13, the drawer 5 can be locked in different positions in the envelope 1, representing these different positions a different length of the boxes
foldable

Figure 3 shows the front area of the drawer with the front wall 9 open. The front wall 9 comprises in its 3 edges respectively narrow tabs 17, which, after closing the lid 9, engage inside the drawer. The tongue 17 provided in the upper edge of the cover 9 comprises a groove 18, which extends along the upper edge. In this slot 18 engages a flip tongue 11 cut out from the upper side 7 of the drawer. In this way, the front wall 9 can be locked in the state
closed.

Behind the plane on the front side of drawer 5 a separation wall 19 can be seen, which extends parallel to this when the cover 9 is closed. In this way form a small compartment in the area on the front side of the drawer 5, which can be used for accessory housing, Service instructions or similar.

Some details of the structure and configuration of the front area of the drawer can be seen from the other Figures, to which reference is now made. Figure 4 shows a vertical section of the front area of the drawer 5. In the upper upper edge 20 a tongue 21 is arranged, which is folded first inside the drawer 5 parallel to the upper side 7 and then at a right angle downwards to form the separation wall 19. The separation wall 19 is bent in the lower area again forward and forms a foot flange 22, which rests on the bottom 8 of the drawer
5.

Figure 5 now shows a sectional view horizontal of the front area of drawer 8. Here you can see that the side walls 6 have been folded inwards in the area from the front side of the drawer 5 forming there tabs 23 interiors, which from the front edge 24 reach more inside of what corresponds to the position of the separation wall 19. These inwardly folded tabs 23 also serve to position the separation wall 19. This can be seen in Figure 6, which represents a front view of the drawer 5 with the lid 9 withdrawal. The separation wall 19 that can be seen in a view front features two protruding sides 25, which engage in corresponding grooves of the tabs 23. At the bottom in figure 6 the front edge of the tongue 22 can be seen, which it rests on the bottom 8 of the drawer.

Both drawer 5 and wrapper 1 have been preferably made of a piece of cardboard by cutting, punching and folding.
