Description

The invention relates to cardboard containers - to cardboard boxes made of corrugated cardboard, and can be used as transport containers, containers for storage and display on a shelf in retail chains. In particular, such packaging in the form of a box is used for storage and display in a storehouse of a product packaged in bags on substrates or confectionery products or groceries. Products on substrates are characterized by a flattened shape and light weight, for example sausage slices, cheese slices, fish, meat, etc., and are stacked vertically in a box to preserve the presentation of the packaged slices. And as confectionery, it is fashionable to consider the ends and cakes, cookies and similar goods. The common feature of these types of products is that they belong to easily damaged types, should not be subjected to pressure from the weight of products adjacent to them, and should not be densely laid.

Substrates are a modern packaging material that is widely used for packaging food products: meat, fish, vegetables, confectionery, etc. Usually used in conjunction with cling film and represent one of the most common types of packaging. In each supermarket, hundreds of goods packed just in such trays. Such a package is convenient in that its contents are easily visible without compromising integrity and tightness. And due to its compactness, trays save space on store shelves and are convenient in transportation.

As a rule, products on substrates are packed in boxes, transported to them and supplied to the distribution network. In the distribution network, products are taken out of the boxes and laid out on the shelves or shelves of the hall. When laying out, time is spent and not always this product is correctly and conveniently laid out on a shelf. When choosing a product unit, the buyer stirs up the packaging on the substrates, destroying the laying on the shelf. The product crumbles if it is stacked in packs one above the other or in a row, falls into the place of placement of another product on the substrate. To eliminate this undesirable phenomenon and preserve the location of each type of product on substrates in its place on the shelf of the trading floor, packages are used that, after the goods are transported, are transformed into show boxes or demonstration boxes or boxes with the possibility of demonstrating the goods. Products from such packages are not removed, it remains in the box, and in the box part of its walls is torn out or separated, forming both a window display and customer access to the products. Since the product remains in the box, then, as a rule, the product also remains in the box, as it is convenient for the buyer to choose the unit that attracts him more without pulling out the entire product.

And confectionery products such as cakes or cakes are packed in polystyrene boxes that do not hold the load and therefore should not be placed on top of one another for more than two or three packages. Therefore, the transportation of this type of product is carried out either without cardboard packaging, or with packing in a cardboard box. But such boxes are not stackable, as the risk of damage to the boxes is high. As a rule, such products are transferred on pallets.

As for groceries, goods such as pasta or vermicelli need to be transported in boxes with free stacking.

Thus, a cardboard box for placing a packaged product is known, which is a four-valve cardboard box, which has a parallelepiped shape and is formed by bending its parts along fold lines from a sheet blank to form a bottom, top, side and end walls, while on the side walls and between them located one end wall there is a line of weakened strength, which is made on the end wall in a horizontal direction at a distance from the bottom less than from the top, and which is on The walls are made obliquely located from the line on the end wall to the corners of the top on the other end wall, while under pressure on the line of weakened strength, the walls break and the box is divided into two parts, the upper of which is to be removed, the valve of the other end wall is made with the possibility of folding and securing in the folded state in the plane of the top by entering the protrusions into the holes in this end wall, and the side walls, on the surface of which inclined sections of the line of weakened stiffness are made are made with additional valves that are bent along the bend line and inserted between the bent parts of the valve of the other end wall, which is made on its surface with a part of the closed surface bounded along the perimeter by a line of weakened stiffness, in the form of a tear-off valve, and the joint of the valve connecting the side walls, forming the top of the box, fastened on top with duct tape, the end of which is fixed on the tear-off valve (RU 109742, B65D 17/28, publ. 10/27/2011).

This decision was made as a prototype for the declared objects.

This box meets its purpose in terms of ensuring the demonstration of goods on the counter. But it was created for storage, transportation and demonstration in the trading floor of egg packages that allow tight packing of the product. In this case, individual egg boxes are themselves packages that can withstand heavy loads. Therefore, the use of cardboard containers for this type of product is beneficial and advisable, since there is the possibility of maximum load carrier body.

However, the situation changes when lightweight goods are packaged in boxes, easily losing their presentation and not enduring loads and pressure, then transportation becomes expensive, since all the carrier’s capabilities are not used in terms of using the transported cargo and filling the body. In order to save goods do not use stacks, which leads to not filling the body.

If you use corrugated boxes with a large wall thickness, which would be guaranteed to exclude the weight load on the packed load, then stacking can be applied. But in this case, the packaging becomes unreasonably expensive in relation to the product. At the same time, there is a large consumption of cardboard for disposable containers.

Cost-effective for corrugated cardboard boxes is the use of three-layer cardboard. But the bearing capacity of such a box is limited by its size. With large sizes, the box loses its ability to bear the load due to the appearance of a deflection of the side walls inside the box or out. To do this, it is necessary to reinforce the box by laying a partition in it or forming stiffeners that would prevent deformation of the side walls. But in this case, either the design of the box is complicated, or the consumption of cardboard increases.

The present invention is aimed at achieving a technical result, which consists in improving operational performance by increasing the spatial stiffness and bearing capacity of a cardboard box with a show-box function for lightweight products to enable its transportation in a column or stack.

The technical result indicated is achieved by the fact that the package, which is a four-valve cardboard box, which has the shape of a parallelepiped and is formed by bending its parts along fold lines from a sheet blank to form a bottom, top, side and end walls, while on opposite sides and between them located one end wall, a line of weakened strength is made, each of which on the side walls is made obliquely located from the line on the end wall to the top of the top is located on the wall between them, while under pressure on the line of weakened strength, the walls break and the box is divided into two parts, the upper of which is to be removed, equipped with an additional four-valve cardboard box, which has the shape of a parallelepiped and is formed by bending its parts along the lines fold from the sheet blank with the formation of the bottom, top, side and end walls, while on the opposite side walls and between them located one end wall A line of weakened strength is filled, each of which on the side walls is made obliquely located from the line on the end wall to the top corners on the wall located between them, while under pressure on the line of weakened strength, the walls break and the box is divided into two parts, the upper of which removal, while both cardboard four-valve boxes are located next to each other with the mutual support of their side walls and are interconnected along the same line of inflection of the same side walls for possible rotation of one box relative to another around this line of inflection.

In this case, the inflection line along which both boxes are interconnected with the possibility of abutment by the side walls and a turn can be drawn along part of its length with lines of weakened strength to disconnect one box from the other.

The technical result indicated is achieved by the fact that the sheet blank for packaging includes a first row of four side walls connected in series through the inflection lines, bent each relative to an adjacent wall to form an open duct, and having flaps on each side of the valve that are bent towards each other to form the bottom box and the lid, and the second row of four side walls connected in series through the inflection lines, each bending relative to the adjacent wall for There are openings of the open duct and having flaps on each side of the flap that are bent towards each other to form a bottom and a lid at this duct, while the side walls of the second row are located symmetrically with respect to the side walls of the first row, and the side wall, which is extremely aligned in one row, is connected through the inflection line with an extremely located side wall of another row for connecting two ducts to each other along this inflection line.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

In FIG. 1 - cardboard sheet blank packaging for light products;

FIG. 2 is a general view of the package with a demonstration of its separation into two boxes and separation of the upper part from each box.

According to the present invention, the design of the developed original packaging made of corrugated cardboard with high bearing capacity due to the guaranteed preservation of the spatial angular zone and the formation of reinforced stiffening ribs, vertically directed, used as a support for the upper placed box is considered. Such a box can be used for stacking, since deformation of the flatness of the side walls is structurally excluded.

In addition, such packaging can also be used for shelving in network markets and is intended for placement, storage, transportation of piece goods for various purposes. This package is made with the function of a transformer for converting a box into a display case or show box in order to demonstrate the packaged goods on the trading floor without transferring the goods from the box to the shelf or rack.

At the same time, the presence of weaknesses on the box walls, which allow the box to be transferred from the packaging and packaging modes to a demonstration box with the function of show-box, do not affect the spatial strength of the box and the stiffness of the angular shapes, which makes it possible to consider this package as a multi-purpose container.

The issue of spatial strength of cardboard packaging such as four-valve boxes is solved by maintaining the flatness of the side walls, which is directly related to the state of the corner zones of the box. Violation of the geometry of the corner zone leads to deformation of the side wall / walls and loss of bearing capacity of the box. Given this feature, the dimensions / dimensions of the box are selected taking into account the weight of the packaged product and the thickness of the corrugated board. Optimized sizes of such packages are compiled in the FEFCO International Catalog. But at the same time, these two conditions are closely related to the dimensions of the package itself, that is, in the dimensions / area of the side walls. With an increase in the area of the side walls of the support function, the corner zones are not enough and it is necessary either to increase the thickness of the cardboard or to use additional structural reinforcements. Both that and leads to complication of the design of the box and cost overrun of cardboard, the cost of which is included in the cost of the final product. The use of dimensional cardboard packaging from a three-layer corrugated cardboard is beneficial for transporting a lightweight product, but for this it is necessary to provide such a package with increased strength so that possible deflections of the side walls do not affect the spatial shape of the container.

To solve the problem of preserving the spatial shape and strength of the package, such as four-valve boxes used for transportation and storage of grocery products, products on substrates (for example, with the vertical arrangement of substrates), it is proposed to provide an additional stiffening rib in the package due to the special execution of the package itself and without the use of additional expense cardboard.

The essence of the claimed invention lies in the fact that the package consists of two four-valve boxes connected to each other on the sides, made, for example, of a three-layer cardboard. In this case, two side walls attached to each other represent a partition reinforced by doubling the wall thickness. This partition is a vertical stiffener for the packaging as a whole, located in its middle part. Moreover, this partition is connected with eight corner zones that act as supports for this double wall.

A specific embodiment of the invention is described below.

Packaging is assembled from a sheet of cardboard blanks (Fig. 1). The sheet blank for the package in question includes a first row of four side walls 2 connected in series through the inflection lines 1, each bending relative to an adjacent wall to form an open box. Each wall has on each edge of the valve 3 and 4, bent towards each other to form a bottom and a cover at this duct. This is a traditionally classic four-valve box design.

The sheet blank also contains a second row, analogous in design, of four side walls 6 connected in series through the bend lines 5, bent each relative to the adjacent wall to form an open duct, and having flanges 7 and 8 on each edge, folded towards each other to form this duct bottom and cover. A box is also assembled from this second row according to the well-known scheme for constructing a four-valve box.

Depending on the shape of valves 3 and 7, the bottom can be made by first laying the first two valves opposite to each other on opposite walls, and then the valves of the other two walls are placed on top of them and these copans are connected with adhesive tape along their contact line. It is possible to execute the bottom by first laying the first two valves opposite to each other on opposite walls, and then on top of them are the valves of two other walls that have a curved edge, due to which one of these valves engages with the other. The same applies to the formation of the upper cover by valves 4 and 8.

In the framework of the present invention, the specific implementation of the bottom and cover is not the main thing. All that matters is their presence.

A feature of the claimed invention is that both rows are arranged in a line and arranged symmetrically. That is, the side walls of the second row are located symmetrically with respect to the side walls of the first row.

Another feature is that the side wall 2, which is extremely located in one row, is connected through the inflection line 9 to the extremely positioned side wall 6 of the other row to connect the two boxes to each other along this bend line.

Thus, a separate box is assembled from the elements of each row of the sheet blank. From the point of view of profitability and practical feasibility, both boxes are the same not only in design but in size. Two assembled boxes are interconnected along a common bend line 9 and can be either pressed against each other (transport and storage mode) or deployed relative to each other around the bend line 9, as around a certain conditional axis of rotation.

Thus, the package consists of two interconnected cardboard four-valve boxes, each of which has a parallelepiped shape and is formed by bending its parts along fold lines from a sheet blank to form a bottom, top, side and end walls (Fig. 2).

Both cardboard four-valve boxes (main and additional) are located next to each other with the mutual support of their side walls and are interconnected along one bend line of the same side walls to allow one box to rotate relative to another around this bend line.

In terms of boxes can be made square or rectangular.

A package consisting of two boxes adjacent to each other has a high load capacity and a high degree of spatial shape retention. This is due to the fact that the shape of the box at its load is held by a double wall, which acts as a central bridge supported by adjacent right angles. When stacking the packages are stacked with overlapping each other (boxes of the next row are located transversely to the boxes of the lower row) or without overlapping (the partitions of the boxes of the upper row are located based on the partitions of the lower row). With this installation, all the boxes rest on the partitions, as the main supporting elements, that is, the weight of each next row falls on the partitions of the lower row of boxes. This is very important, as the unloading of the walls of the boxes from weight load occurs. Thus, the packaged product is not under the stress of the weight of the upper packaging. At the same time, it becomes possible to use stacking of packages during transportation and storage, as a way to maximize the use of space (including the volume of the carrier’s body).

Since the partitions are made of double walls and unload the side walls of the package, taking on a weight load, it becomes possible to use a three-layer cardboard. Double wall - a partition made of double three-layer cardboard has high strength and high bending resistance, exceeding the same performance of single-sheet cardboard with a large number of layers. Due to this property, products whose dimensions (for example, in height) are smaller than the dimensions of the cavity of the box can be placed in boxes.

During transportation and storage, both boxes connected to each other through the inflection line 9 are in a position where both boxes are mutually supported against each other with the adjoining side walls. It turns out a parallelepiped block. When positioned on the trading floor, the boxes can be deployed relative to each other, as shown in FIG. 2. At the same time, it is possible that the inflection line 9, along which both boxes are connected with the possibility of abutment by the side walls and a turn, is made part of its length with lines 10 of weakened strength or with cuts that allow one box to be disconnected from the other to obtain two identical boxes.

Such boxes can be laid out on the trading floor. To turn the box into a demonstration box (show box) for display on a shelf of the trading floor, along with products on opposite side walls and between them located one end wall, a line 11 of weakened strength is made, each of which on the side walls is made obliquely located from the line on end wall to the corners of the top on the wall located between them. When the pressure on line 11 of weakened strength occurs, the walls break and the box is divided into two parts, the upper of which is to be removed (Fig. 2). The lower part 12 of the box remains open with the goods packed in it.

The present invention is industrially applicable and may find application as packaging for the storage, transportation and display of lightweight products. The demonstration function of packaging is expressed in open visual access to packaged products through an open doorway.
