Description

The present invention relates to a box and a blank for forming it. More specifically, the present invention relates to a box containing a jumper configured to be inserted into a recess between, for example, combined cups or pots in so-called. briquette packaging.

Such groups of packages may consist of a single pair of packages, or the packages may be in any other desired arrangement, for example, in two rows of two packages in each row, in two rows of three, four or five packages in each row, or in more rows with the desired number of packages. Typically, such packaging is relatively small, and in order to ensure effective handling of them during transportation and sale, it is desirable to stack them in rows.

For the purposes of this application, each cup or pot is considered as a separate package (product). Some cups or pots are divided into sections (for example, yogurt pots, in which the flavor is in a section separate from the yogurt).

This invention, in particular, relates to a jumper connecting the side or top wall of the box with its bottom wall, so that the longitudinal axis of the jumper is inclined relative to the plane of the top wall of the box and enters the recess between adjacent pots. With previous jumpers, the application of the carrier on the real products from below was required. Examples of such carriers are described in EP 0972718 A1 (Gosan Beauvais), FR 2483399 (Calvet).

One problem associated with such carriers is that they are incompatible with traditional wrapping packaging equipment in which the carrier is placed on top or bottom of a group of products and wrapped around it.

The present invention aims to eliminate or at least reduce the problems of the prior art.

According to a first aspect, the invention provides a wrapping box for packaging two or more products with a recess between adjacent products, which comprises an upper wall, a side wall, a lower wall and a bridge structure disposed to form a tubular structure surrounding the article, wherein the bridge structure is designed so that it could fit in a recess, and at one end it is pivotally connected to the bottom wall.

The box is preferably provided with a second side wall, with the second end of the jumper pivotally connected to the second side wall. The second end is preferably pivotally connected to the second side wall between the upper edge and the bottom of the product.

Alternatively, the second end of the jumper is pivotally connected to the top wall of the box.

According to an optional feature of this object of the invention, the jumper comprises a pair of support walls pivotally connected along a common longitudinal edge. The support walls may form an acute angle between them to facilitate the formation of a bridge.

According to another optional feature of this object of the invention, the jumper further comprises a middle wall between the supporting walls, which is pivotally connected to them along their common longitudinal edge.

According to yet another optional feature of this object of the invention, the support walls are pivotally connected to an adjacent wall by means of one or more connecting walls, which may be trapezoidal in shape.

In some embodiments, the box may further comprise a pair of wedge walls pivotally connected to said connecting walls and bent away from a position aligned with them, wherein said pair of wedge walls pivotally connects said supporting walls to said connecting walls.

According to an optional feature of this object of the invention, a part of each of said support walls may abut against the wall of adjacent products.

According to a second aspect, the invention provides a blanket for a wrapping carrier comprising several wall panels pivotally connected in a row with one another, the wall panels including a pair of lower panels at opposite ends of the blank, one of the lower panels being connected to an adjacent wall panel by a section forming a jumper which includes a connecting wall pivotally connected to the bottom panel, and a pair of supporting walls, which are both connected to the connecting wall and continue to the specified osedney wall panel.

Preferably, the opposite end of the web is pivotally connected to the side wall. Preferably, the distance between the fold lines along which the side wall is pivotally connected respectively to the jumper structure and the upper wall panel is less than the distance between the top and bottom of the product being packaged.

Alternatively, the first end of the jumper is pivotally connected to the top wall panel of the box.

According to an optional feature of this object of the invention, a pair of support panels can be divided by a middle panel.

According to yet another optional feature of this object of the invention, the preform further comprises a pair of wedge panels pivotally connected to said connecting panel, wherein said pairs of wedge panels pivotally connect said supporting panels to said connecting panel.

According to a third aspect, the invention provides a method for forming a box from a blank, comprising the steps of:

- feed to the workpiece groups of products with a recess between adjacent products,

- introducing into the recess of the jumper forming the portion of the workpiece to cause the support panels to bend from the aligned position and their interaction with the walls of adjacent products,

- and bending upwards of the lower panels to an overlapping position for fastening them.

Now, as an example, some embodiments of the invention will be described with reference to the accompanying drawings, in which:

Detailed description of preferred embodiments.

The drawings and, in particular, figure 1 shows an example of a blank 10 made of cardboard or a similar bendable sheet material for forming a wrapping box according to the invention, having several panels for forming a bridge structure 14 therein and intended for packaging one or more products. The blank comprises several panels arranged in a row to form a box having a top, bottom and opposite side walls. In this embodiment, the preform comprises a first lower wall panel 12, a jumper structure 14, a first side wall panel 16, an upper wall panel 18, a second side wall panel 20 and a second lower wall panel 22 pivotally connected to each other along fold lines 30, 32, 24, 26 and 28.

The design of the jumper 14 continues between the first lower wall panel 12 and the first side wall panel 16 and is pivotally connected to them by a pair of connecting parts. Thus, the design of the jumper 14 can be placed between sections of the product (s) to support them. Preferably, the structure of the jumper 14 is cut out at least in part of the first lower wall panel 12 and part of the first side wall panel 16, so that parts of these wall panels that do not form a jumper form part of the outer walls.

In this embodiment, each connecting part comprises a connecting panel 34, 36 pivotally connected along one edge respectively with the first lower wall panel 12 along the fold line 30 and the first side wall panel along the fold line 32. Preferably, the connecting panels 34, 36 are substantially trapezoidal shape, and fold lines 30, 32 are along their longest edges. Each connecting panel 34, 36 at each of its opposite beveled side edges is pivotally connected to a pair of wedge panels 42a, 42b, 42c and 42d along fold lines 44a, 44b, 44c, 44d, respectively. In the preferred embodiment shown in FIG. 1, the wedge panels 42a, 42b, 42c and 42d are substantially triangular in shape. Of course, the shape of the connecting panel and / or the wedge panels is not limited to the shape described above, and other shapes are possible to provide a bridge, for example with a substantially V-shaped inverted cross section.

Wedge panels 42a and 42b are pivotally connected to the ends of the first and second support panels 38 and 40 along the fold line 46a to support the articles. In addition, the wedge panels 42c and 42d are pivotally connected to the opposite ends of the first and second support panels 38 and 40 along a fold line 46B.

In this embodiment, the middle panel 48 separates the support panels 38, 40 and is pivotally connected to them along its bending lines 50 and 52 along its lateral edges. Preferably, the middle panel 48 is pivotally connected to the shortest edge of the connecting panels 34 and 36 along fold lines 46a and 46b.

Returning to the box shown in FIGS. 2, 3 and 4, it is envisaged that the box according to the invention can be formed by a series of successive bending and possibly gluing operations, which can be carried out on a known machine with a straight line, since the box does not need to be turned or turned to complete its formation. The bending method is not limited to what is described below and can be changed in accordance with specific production requirements. Items shown are inverted for clarity only.

As shown in figure 2, the upper wall panel of the workpiece 10 is brought into contact with the upper flat surface of the products And through their vertical movement between them. As shown in FIG. 3, the preform 10 is then partially folded to form a pair of opposing side walls by folding the side wall panels 16, 20 inward along fold lines 24 and 26. The connecting walls 34, 36 are bent from a position aligned with the first lower wall panel 12 and a first side wall panel 16, so that the first lower wall panel 12 covers the bottom of the products A.

Meanwhile, or at the same time, a jumper structure is formed by folding the first and second support panels 38, 40 along the fold lines 50, 52 at an angle to each other and to the middle panel 48 (Fig. 4), so that the middle panel 48 is the uppermost. The bending of the first and second support panels 38, 40 simultaneously causes the wedge panels 42a, 42b and 42c, 42d to bend from a position aligned with the connection panels 34, 36.

Preferably, the first and second support panels are bent automatically due to the introduction of a jumper in the gap between adjacent products A. For this, the width of the middle panel 48 is equal to or less than the distance between adjacent pots, but the total width of the unbent structure of the jumper 14 is greater than the distance between the pots. The elasticity inherent in bent cardboard ensures that a tight fit is maintained between the supporting walls 38, 40 and the products.

Then, a second lower wall panel 22 is folded onto the base of articles A and attached to the first lower wall panel 12 using glue or other suitable means known in the art, for example a mechanical fastening means, forming a composite lower wall. The box is now fully assembled, as shown in FIGS. 4, 5 and 6, with the formation of a jumper with a cross section of a substantially U-shaped inverted shape.

It is envisaged that the angular relative position of the support panels 38 and 40 can be changed by moving the crease lines 44a, 44b, 44c, 44d and / or the crease lines 46a, 46b in accordance with the specific requirements of the jumper 14. The shape of the connecting walls 34, 36 is not limited to trapezoidal form. In other embodiments of the invention, the support walls may bend upward to form an inverted web structure. In some embodiments, the second lower wall panel may be extended to cover the entire bottom of the box and may be provided with a valve for attachment to the first side wall panel 16.

In some embodiments, the supporting walls of the jumper may be bent, as shown in FIG. 5, to interact with products to increase the rigidity of the box. In these embodiments, the support walls act as engaging strips. The walls 38, 40 are preferably bent along the fold lines 44a, 50, 44d and 44b, 52, 44c, and these fold lines can be oriented so as to better fit the shape of the adjacent product.

A second embodiment of the invention is shown in FIGS. 7, 8 and 9, where the same parts, if possible, are indicated by the same positions with the addition of the number “1” in front. The second option is similar to the first option, so only the differences are described in detail.

In particular, the blank 110 shown in FIG. 7 differs from the blank according to the first embodiment in that the first side wall panel is absent and the construction of the bridge 114 is thus pivotally connected directly to the upper wall panel 118 along the fold line 132. Additionally, the construction jumpers are increased in length to compensate for the absence of the first side wall panel.

Considering the construction of the jumper 114 in more detail, it can be seen that in this embodiment of the invention, the support walls 138 and 140 are pivotally interconnected along a common fold line 143 and that, in addition, there are no wedge walls, so that the support walls 138 and 140 are trapezoidal and pivotally connected directly to the connecting walls 134 and 136 along the fold lines 135, 139 and 137, 141, respectively.

Regarding the formation of the fully assembled box shown in Figs. 8 and 9, it is envisaged that the box according to the second embodiment of the invention can be formed by a series of successive folding and gluing operations that can be performed in a straight line, since it is not necessary to rotate or turn the box over to complete its formation.

The folding operation is essentially the same as for the first embodiment of the invention, and leads to the formation of a tubular box surrounding the article A. After this, the first and second lower wall panels 112 and 122 are fastened together using glue or other suitable means known from the level techniques to form a composite bottom wall shown in FIG.

The design of the jumper 114 is formed by folding the first and second support walls 138 and 140 along their common fold line 143 at an angle to each other, so that the fold line 143 is the uppermost in this embodiment. Preferably, the first and second supporting walls are bent automatically due to the introduction of a jumper 114 into the gap between adjacent products A. For this, the width of the supporting walls 138, 140 in the coplanar state is greater than the distance between adjacent pots. And in this case, the elasticity inherent in bent cardboard ensures that a tight fit is maintained between the supporting walls 138, 140 and the products.

Those skilled in the art will appreciate that the combination of a wrapping box with an inclined jumper inserted between the products substantially prevents the relative movement of products A and the cardboard box, which could interfere with the automation of transport and stacking of the boxes. Thus, the jumper can be used in place of the end holding means that has been used so far to prevent relative horizontal movement between the products and the cardboard box, but which usually required an additional folding step as part of the box assembly process.

It should be borne in mind that the terms “top”, “bottom”, “side”, “upper” and “lower”, used here in relation to the walls of the box, are relative, since the box may have a different orientation if necessary or if desired. Any reference to swivel joints should not be construed as a single fold line: in fact, within the scope of the invention, a swivel joint may be formed by a cut line, a weakened line, or one, two or more fold lines.

The present invention and its preferred embodiment relate to a jumper in a wrapping box that is strong enough to hold at least one article securely, but with some degree of flexibility, so that the load transferred to the jumper is absorbed by the box. The shape of the blank allows you to minimize the amount of cardboard required. The box can be applied to a group of products manually or on automatic equipment.
