Abstract

A double-walled carton is assembled from a single folded blank. The carton has a base, double-walled sidewalls (3,4) and a double-walled opening front panel. The rear wall also incorporates a folding lid with the base and lid consisting of single layers. The carton is very strong, because all upright parts are double-walled.

Description

Folding box.

The invention is based on a folding box specially designed to contain small metal parts like screws This type of folding box consisting of a unit that can fit in a wrap is already known. The front of the box is formed as a spout. This one can open bending forward. They are also incorporated side tabs between the unit that can be fitted and the envelope. The lateral tabs prevent lateral sliding of objects and simultaneously limit the opening position Maximum flap.

A box is also known (DE-U-69 36 972), in which the fund It is single layer, while the side walls and the wall Front are double layer. The back wall, in which it articulate the lid, it has only one layer.

In addition a box is known (DE-U-296 13 255), in which the bottom is formed by a double wall. In this box it is not possible adapt a single wall background.

In addition, a folding storage carton is known (DE 8600769 U1), in which the two side walls are formed for a double layer. The rear wall and the folding front wall They are formed by a single layer.

In another folding package consisting of only one piece with folding cover (DE 6936972 U1), these side walls and the non-folding front wall are made of a double layer, the rear wall however is formed by a single wall.

In other packaging that can be manufactured from a cutout, the two side walls are double, the front wall and The back wall however are single layer. This packing It has no folding front part (FR 2623131 A1).

The objective of the invention is to create a box folding which, having a simple structure, offers the possibility of placing small parts inside not only during transport, but also on the delivery shelf.

For the solution of this objective the invention proposes a folding box with the characteristics of the claim 1. The improvements of the invention are subject of dependent claims, whose text is written equally that the text of the summary, referring to the content of the description.

While the known box consists of two parts, the box proposed before the invention consists only in a cutout This cut can be stamped in a phase of operation and for example can be provided with fold lines. For the construction of the box, the cutout should only be folded and insert

According to the invention it is provided that the walls sides of the folding box are formed by a double layer. This double layer of the side walls is especially useful for Increase the stability of the box. The boxes after filling are not they will find only on a shelf, of which the user can remove the pieces, but will be used throughout the transport. This time the boxes are superimposed, so that its weight including the weight of its content presses on the boxes arranged below. Since the boxes are usually longer than wide, the side walls assume a large part of this load.

According to the invention, it is also planned to carry out the back wall with a double layer. The double layer of the wall later not only serves to increase the stability of the boxes, It has another use. When they are in the box for example screws, these are usually found in the longitudinal direction of the box, particularly when it comes of relatively long screws. Here it may be the case that, during transport, the screws tighten with their tips against the back wall. In this way a double layer of the wall later also prevents deterioration of the boxes due to their content.

According to the invention it is also provided that the front wall be double. This has the same purpose as the double layer of the back wall and also of the side walls. Additionally there is another advantage, since the boxes frequently placed on shelves with diagonal bottoms inclined Here the small parts of the box press against the front wall due to its own weight.

The bottom of the box consists of only one layer according to the invention. Also the lid, which forms the part top of the box, can be formed by a layer.

In an improvement it is proposed to articulate the cover to the upper edge of the back wall and open it by this edge. It was particularly reasonable to articulate the lid in front of the front wall, since opening the cover backwards facilitates the removal of the pieces of the box.

The invention proposes to configure the front wall of the folding box so foldable so that, as in the state of the art, the possibility of folding can be limited by lateral tabs.

The invention proposes to configure the lid of the folding box so that it can join with the side walls. This can happen for example when the cover has tabs on the area of its lateral edges that can fit into openings similar to grooves on the upper edge of the side walls or in the area of the upper edge. These tabs can also be something fitted when you want to configure the lid so that you don't  It can open easily.

According to the invention, in an improvement it can be provided that the cover can be joined with the front wall Folding or not folding. When the front wall is not foldable, This union serves to close the folding boxes. When the wall front is foldable, this feature also serves to keep front wall closed.

In another refinement of the invention may provide that the cover is formed so that it can only be open in a part that begins at the front of the lid. For this, the lid can have, for example, a fold line or additional fold extending transversely to its length.

It can be provided that the lid can be retained or lock in partially folded state. For this purpose you can used for example a surface zip closure or a similar device.

Particularly favorable is the cover that it has a tongue that can be inserted into an opening of the same.

According to the invention, it can be provided tab for joining the lid with the front wall and for its Close in open state.

Other features, details and advantages of the invention result from the following description of a form of preferred embodiment of the invention as well as the drawings. The Drawings show:

Figure 1 flat cut for the construction of a box according to the invention;

Figure 2 the box in perspective in a state partially built;

Figure 3 representation of the built box partially open

Figure 1 shows a cutout, which can be cut for example of corrugated cardboard, thin corrugated cardboard or similar. Additionally figure 1 shows in drawn lines the fold lines 2 that must be formed later or already They are formed in the cutout. Approximately in the center of the the rectangular bottom 1 of the box can be seen. East bottom is limited on all sides by fold lines 2, which They are represented by drawn lines. On the sides longitudinal of bottom 1 always follow two sections 3, 4, which meanwhile they are separated from each other by lines of folding 5. Both sections 3, 4 form the side walls the box being folded, so that sections 4, which in the cutout are found on the outside, form the walls internal and sections 3, which are between aforementioned and the bottom 1, form the outer walls of the side walls. In the area of free outer edges 6, sections 4 contain two narrow insert tabs extended 7 which, seen in the longitudinal direction of the box, are  arranged at points equal to the slit-shaped openings 8, which are arranged along the lateral edges of the bottom one.

At the point of separation defined by the lines folding 5, between the outer wall 3 and the inner wall 4, is also provided a slot-shaped opening 9 that extends in the longitudinal direction, which is on the edge upper side wall while the box is upright.

On the bottom side represented in figure 1, a section 10 is always next to the sections of the side walls that form the inner wall 4, being separated of the inner wall 4 by a fold line 11. Dimension 12 of this section 10 in the longitudinal direction of the cutout corresponds to a half transversal extension of the bottom 1, that is to say corresponds to the width of the box.

Reference is made below to the description of the cutout pieces placed in the bottom 1 that They follow it in the longitudinal direction. On the upper short edge of the bottom 1 shown in figure 1 a section 13 is fixed separated by a fold line 2. This section 13 follows a large section 14 with almost the same dimensions, which in turn is  separated by a fold line 15. The dimension of the sections 13 and 14 measured in the longitudinal direction of the cutout is equal and corresponds to the dimension of sections 3 and 4 measured in cross direction. This dimension 16 represents the height of the folding box

Along the fold line 15, between sections 13 and 14, a slot-shaped opening 17 is cut. With the two remaining edges of section 13 it is joined by each edge a section 19 in the form of a quarter circle, being separated by a fold line 18. Sections 13, 14, 19 together form the front wall of the box. At the end of the section 14 opposite the bottom 1 is formed a tongue of insert 20, which in its arrangement corresponds to the opening in groove shape 21 along the separation lines between the fund 1 and section 13.

In opposition to the sections that form the wall front follows bottom 1 a section 22 that later forms the back wall On the two side edges of the back wall 22 is a section 23, which forms a lateral limitation of the back wall 22.

On the side of the rear wall 22 opposite the junction line with bottom 1, lid 25 is separated by a folding line 24. The cover 25 presents in the area of its two longitudinal edges 26, in each of these, a tongue 27 provided with a later cut.

In the area of its free end, the cover 25 Contains an insertion tab 28.

The cutout is symmetrically formed to a line in longitudinal direction, crossing this cut.

The cutout described and represented in figure 1 It can be erected and folded as follows to build box. First, the rear wall 22 is folded, around of its junction line with bottom 1 at 90 ° and then it fold both sections 23 also 90 ° inwards. The cover can then be folded also in a line 24. Next sections of sector 19 are folded in 90 ° inwards, and section 14 at 180 °, so that it comes to rest on the inside on the outer side of the front wall. The tongue 20 it is inserted in this way in slot 21. Then the front wall it rises upwards around the line of union with the bottom 1. In this way the state is achieved as shown in the figure 2. Naturally the succession of wall folding can be changed Front and back wall.

Now the side walls fold. For such object sections 3 are folded up and sections 4 inland. Before or at the same time the two can be folded sections 10 in the opposite direction, that is from the state of the cutout placed flat down, as indicated by the left in figure 2. Sections 4 are pressed around the upper edges of sections 23 and 19 inside the box. The insert tabs 7 are pressed into the slots 8. From This way the box is maintained. At this moment the box is finished and can be filled from the open top side. Cover 25 can then close. For this purpose it bends around junction line 22. Insert tabs 27 are inserted in slots 9, see figure 1. Since the tabs of insert 27 i are somewhat fitted, this results in a kind of lid closure with side walls. The tongue of insert 28 can be inserted into slot 17 at the end of the lid, so that the front wall 13 is closed, having the possibility of opening.

Cap 25 contains another fold line 29, see figure 2, which is arranged almost in front of the tabs insert 27. Around this fold line 29, the part front 30 of the cover 25 can be opened by folding, as schematically depicted in figure 3. The insert tab  28 can be inserted into a slot-shaped opening 31 in the lid 25. In this position the box can be placed for example in a bookshelf, so that the user can see the contents of the box. To remove it, you can also open the front wall 13.

The box contains a double rear wall, a double front wall and double side walls. Sections 10 fixed to the side walls thus form the inner wall of the back wall 22. No connection is required here either glue or adhesion. Nowhere in the box is a three layer wall.

The bottom 1 and the cover 25 instead are single layer, since they contribute less to the stability of the box than the vertical parts
