Description

The invention relates to cardboard boxes used for packaging products packed in individual bags. In particular, we are talking about products such as chips, snacks, crackers, etc., which are packed in soft, easily crushable bags. The utility model also applies to cardboard boxes (dispensers) that can be laid out on the trading floor and turned into a show box, endowed with the ability to demonstrate goods to the buyer and easily remove individual bags from the cavity of the box.

Snack miles chips are traditionally packaged in soft, easily deformable laminated bags, but the products themselves are overwhelmingly fragile goods (for example, chips). Therefore, in the package itself (bag), the product is not packed tightly with freedom of movement. At the same time, laying in the box is carried out so that the bags stand vertically. Given this circumstance, when packing, the tight packing of the bags in the box is excluded. In addition, when transporting and moving a box with sachets, the products in the sachets are subjected to shaking, vibration and shaking, which lead to compaction of the product due to the penetration of the top chips into the space between the chips laid in the bottom area. Shaking or shaking during transportation or when laying out goods on a trading shelf leads to breaking the products, turning them into crumbs.

In this regard, today it is considered correct to exclude such a factor as the cost of human labor, in which the laying out goods should carefully treat the laid out products. But even so, there is no guarantee that when removing the package from the shelf, the consumer will not accidentally destroy the stack of packages and they will not fall to the floor.

To exclude manual display and ensure the non-spillage and safety of the product laid out on the shelf, boxes are used that have the function of turning into a show box, endowed with the ability to demonstrate packages to the buyer and easily remove individual packages from the cavity of the box. Thus, manual display is excluded and the safety of packages and their contents on the shelf of the trading structure is ensured. The show box function is achieved by the fact that after placing the box on the shelf, the operator presses on a part of the wall of the box and tears it off, forming a window or opening for access to the goods inside.

An example of such a device for storage and subsequent removal of the product is a combined package, which includes a cardboard box, inside which packages with the product are placed and which has the shape of a parallelepiped with a bottom, top, side and end walls, on which perforation is made, forming lines of weakened strength, on the side and end walls there is a perforation, forming the first closed line of weakened strength, made in such a way that when exposed to it, the upper part of the box is separated in the form of a removable cover. In this case, two sections of the first closed line of weakened strength, lying on opposite walls of the box, are parallel to each other and oriented obliquely, and the other two sections, lying on the other two opposite walls, are oriented horizontally. In addition, a perforation is made on the end or side wall, forming a second closed line of weakened strength, upon impact on which a window is formed. The second closed line of weakened strength, forming a window, is located on the side wall, on which there is a horizontal section of the first closed line of weakened strength (RU No. 40994, B65D 17/28, publ. 10.10.2004).

Also known is a box for packages with snack products, made of cardboard by bending parts of a sheet blank, including side walls connected in series through the bend lines, each bent relative to an adjacent wall to form an open box and having valves from the upper edge that are bent towards each other. to form the bottom of this box, and from the lower edge, the valves are bent towards each other to form the top of this box, while on one side wall located between the other two side walls, a part of the surface is limited by a closed line of a weakened section to form a surface area to be removal by pressing it, on the other side walls adjacent to the side wall with the removed part of the surface, a line of weakened section is made on each, which is a continuation of the previously mentioned line of a weakened section and which ends at the inflection line of the valve from the upper edge of the the upper flap of the side wall with a removable part of the surface located between the other two side walls is made with two through holes located along the edges of this flap, the top flap of the oppositely located side wall of the box is made consisting of two parts sequentially located through the inflection line, one of which is subject to bending relative to the side wall, and the other is subject to bending relative to the first part with the insertion of its tongues into the slots on the line of inflection of the first part relative to the adjacent side wall to form a partition between other opposite side walls, the upper flaps of which are made with tongues inserted into the through openings of the upper valve of the side wall with a line of weakened section (RU No. 191983, B65D 5/72, publ. 08/29/2019).

This solution is taken as a prototype.

The well-known box is a four-valve box in the form of a regular parallelepiped, in which all corners are made straight, and the side machines are flat. The shape-preserving power contour of such a box is ensured by the safety and integrity of right angles, which allows each side wall to be considered as a support for adjacent side walls. The side walls have elastic deformation and therefore withstand the load within this deformation, but when the corner is deformed, the edge part of the wall is displaced and its position is disturbed in relation to other side walls. The integrity of the box is broken and it ceases to bear the load and cannot be used as part of a stack or column.

In the known solution, the transformation of the box into a show-box is carried out by cutting out a part of the surface of one side wall and by cutting out a part of the wall surface located adjacently. Thus, one opening is formed immediately on two walls. Right angles in the box remain intact, but the walls cease to function as supports for each other. In fact, the box in the show-boxing state turns into an open tray, in which the lower belt (the area at the bottom of the box) retains its strength and integrity, and the upper belt ceases to be power and cannot bear the load, since any loading leads to the loss of a flat shape side walls and their turn around the corner area or corners. This leads to the fact that only one box of products can be placed on the trading shelf. The formation of a small column, for example, from two or three show boxes will lead to the loss of stability of the column and its destruction even under a small lateral force (for example, as a result of a push or grazing).

Such products as chips, for example, belong to the category of lightweight goods, which allows them to be laid out in boxes of a fairly large size. But, since such boxes of a parallelepiped shape have high strength, in order to optimize production, non-sorted cardboard of reduced thickness is used. This leads to savings in material, but affects the load-bearing capacity of the boxes to be stacked. Products in such boxes are not packed tightly. Therefore, only the box itself bears the entire load. But here another problem arises. With an increase in the dimensions of the box, its ability to deform begins to manifest itself due to the fact that the side walls have a large surface area at which the corrugated cardboard begins to sag. With large dimensions, the algorithm for maintaining and maintaining the integrity of the shape of the parallelepiped by keeping the corners straight does not function to the extent that it takes place in boxes of standard sizes (for example, 630 × 320 × 340, 500 × 300 × 300, 300 × 300 × 300 or 800 ×600×600).

In this regard, it becomes relevant to change the shape of a corrugated cardboard box for commercial products in order to provide it with a high load-bearing capacity in a stack and shape retention when laid out in a show-box mode on a shelf in a store and when at least two show boxes are placed on top of each other. friend. In this case, we are talking about boxes classified as standard in size, which are traditionally used for packaging and transporting products for retail stores.

From the prior art boxes of increased bearing capacity, which is provided by increasing the number of side walls (EN 2128136, 2157330, 2740656). The increase in the bearing capacity of such multifaceted boxes has been proven by the practice of their application. This property allowed the use of thin-sheet cardboard and corrugated cardboard of reduced thickness. But these boxes have a drawback, which is that this technique (increasing the number of side walls) works well on small boxes: cigarette or candy boxes. In addition, it is structurally impossible to implement the show-box mode in such boxes.

The present invention is aimed at achieving a technical result, which consists in increasing the carrying capacity of the box, in which an opening developed in area is organized for convenient and easy removal of individual products in the show demonstration mode under any conditions and positions of the box itself.

The specified technical result is achieved by the fact that the octagonal box for storing products and extracting them from it is made of cardboard by bending parts of a sheet blank, which includes side walls of the same height connected in series through the inflection lines, each bent relative to the adjacent wall to form an open box and having valves on one end, bent towards each other to form the bottom of this box, and on the other end of the valve, bent towards each other to form the top of this box, while between each two adjacent side walls there is a side wall of a smaller width than the connected with it through the inflection lines of the side walls, the height of each valve of each side wall, which is attached to the side wall of smaller width, in the direction from the inflection line of this valve from the side wall is less than the length of the side wall, the height of each valve of each side wall, which is connected to a side wall of smaller width, in the direction from the inflection line of this valve from the side wall is made less than the length of the side wall, on the surface of one side wall, which is attached to the side wall of smaller width, a line of weakened section is made, stretching along the inflection line in the bottom formation zone , along the inflection lines of the side walls associated with it of a smaller width and along the surface of its valve used to form the top, to the free edge of this valve, while forming the bottom and top of the box due to the bending of the valves towards each other at the bottom and on the surface of the top of the box openings are formed.

At the same time, in the section of the line of the weakened section, stretched along the inflection line in the zone of formation of the bottom, an opening can be formed to capture the torn-out part of the wall. Or, on this section of the line of the weakened section, a tongue can be formed that is bent inside the box to form an opening and capture the torn-out part of the wall.

The specified technical result is also achieved by the fact that the octagonal box for storing products and extracting them from it is made of cardboard by bending parts of a sheet blank, which includes side walls of the same height connected in series through the inflection lines, each bent relative to the adjacent wall to form an open box and having a valve on one end, bent towards each other to form the bottom of this box, and on the other end of the valve, bent towards each other to form the top of this box, while between each two adjacent side walls there is a side wall of smaller width, than the side walls connected with it through the inflection lines, the height of each valve of each side wall, which is attached to the side wall of smaller width, in the direction from the inflection line of this valve from the side wall is less than the length of the side wall, the height of each valve of each side wall, which which is attached to the side wall of smaller width, in the direction from the inflection line of this valve from the side wall is made less than the length of the side wall, on the surface of one side wall, which is attached to the side walls of smaller width, a line of weakened section is made, stretching along the inflection line in the formation zone bottom with access to the surface of adjacent walls of smaller width, along which this line is continued towards the top of the box until it exits at the free edge of each wall of smaller width, and when the bottom and top of the box are formed due to the bending of the valves towards each other at the bottom and on the surface of the top boxes formed openings.

For this embodiment, on the side wall inside the section of this wall, bounded by a line of weakened section, fold lines can be applied, extending from the section of this line, stretched along the bottom, to the corner points at the edges of the inflection line of the upper located valve from this side wall.

These features are essential 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 specific examples of execution, which, however, are not the only possible ones, but clearly demonstrate the possibility of achieving the desired technical result.

According to the present invention, the construction of an original corrugated cardboard box is considered, which is used for the storage and transportation of products packed in easily collapsible bags for products such as chips and the like. At the same time, such a box can be used when laying out on the trading floor as a demonstration show box (dispenser) due to the formation of openings on at least two walls for demonstrating the packaged goods in the open state and so that the buyer can easily remove individual packages.

In the general case, a box for storing products in bags and extracting them from it is made of cardboard by bending parts of a sheet blank. As a cardboard, for example, brown or white three-layer cardboard of the T-21, T-22, T-23 and T-24 brands can be used.

The sheet blank has side walls arranged in series and interconnected along the inflection lines. In this case, it is conditionally possible to divide these side walls into main and additional. The difference of the additional side walls is that they are made with a width smaller than the width of the juth main side wall. In addition, additional side walls are located between the main ones along the edges of the main walls (at least on the edge of one extreme side wall). This distinction is conditional, but it will make it possible to clearly state the essence of the claimed utility model.

In relation to the main side walls, the concepts of "side" and "end" side walls are used. These terms are used to understand the principle of bottom and top formation. Such terms can be used for a box of rectangular shape in plan, when some side walls are longer than the other walls. In principle, the box can have the shape of a square in plan, and in this case the terms "side" and "end" walls for the box become conditional in view of the equivalence in size of all the walls.

In the general case, the constructive algorithm for constructing an octagonal food storage box is as follows (for all examples of execution).

The box is made of cardboard by bending parts of a sheet blank, which includes side walls of the same height connected in series through the bend lines, each bent relative to the adjacent wall to form an open box and having a valve on one edge, bent towards each other to form the bottom of this box , and from the other end of the valve, bent towards each other to form the top of this box.

Between each two adjacent side walls there is a side wall of smaller width than the side walls connected with it through the inflection lines.

The height of each valve of each side wall, which is attached to the side wall of smaller width, in the direction from the inflection line of this valve from the side wall is less than the length of the side wall.

The height of each valve of each side wall, which is attached to the side wall of smaller width, in the direction from the inflection line of this valve from the side wall is less than the length of the side wall.

At the same time, when the bottom and top of the box are formed, openings are formed on the bottom and on the surface of the top of the box due to the bending of the valves towards each other.

Examples of implementation of the invention are discussed below with reference to FIGS. 1-10.

In the first embodiment (Fig. 1-4), all side walls of the box are arranged in the following sequence: main side wall 1, additional side wall 2, main side wall 3, additional side wall 4, main side wall 5, additional side wall 6, main side wall 7, additional side wall 8. The main side wall 1 from the free edge is made with a valve 9 used for adhesive connection of this wall 1 when assembled with wall 8 to obtain a box (gluing is shown in Fig. 3). But, as an embodiment, this valve 9 can be located on the edge of the additional side wall 7 and glued to the inner surface of the side wall 1. All walls are connected in series with each other through the inflection lines 10.

Since the invention is considered on the example of a rectangular box in which some main walls are made smaller than others, the main side walls 1 and 5 can be called end, and the other main side walls 3 and 7 are simply side. Side walls 2, 4, 6 and 8 are additional walls.

When assembling the shell from walls 1-8, all walls are folded along the kink lines 10 and the valve 9 is glued to an additional wall 8. The place of gluing 11 is shown in Fig. 3 (the shell is assembled and folded into a flat blank).

As a rule, four-clan type boxes are made with a closed internal volume, that is, all valves are joined together. This is necessary to maintain the shape of the box and box and to preserve the presentation of the products. But a product as lightweight as bagged chips does not require a closed internal volume. Their presentation is supported by the form of packaging. Therefore, there is no need to make the box completely closed and sealed. With respect to the box of the four-clan type, the presence of openings in the side walls or in the corner zones sharply reduces the strength of the box. But for an octagonal box, the presence of openings does not reduce the strength of the structure. This is explained by the fact that in the absence of right angles in the wall joining zones, each face between the side walls becomes a stiffening rib for the side walls associated with it. In this case, this rib is extended along the entire height of the box. When a load appears in the plane of the side wall surface, it changes its vector on the fold lines of the walls, which makes it possible to maintain the high strength of the box, even if openings are made in it. This is confirmed by the decision on MX 2019009902, in which an octagonal box with additional walls is protected, the width of which is less than the width of the main walls of the box. This document says that such an implementation of the side walls can significantly increase the bearing capacity of the box and the preservation of its spatial shape. The use of this technique made it possible to increase the strength characteristics of the box up to 33% (compared to the standard four-valve box used to transport bags of chips).

To form the bottom, the end walls 1 and 5 are equipped with lower valves 12, and the side walls 3 and 7 are equipped with lower valves 13. those valves that are located outside the box). As an option, which is shown in Fig. 1, valves 13 are made with slots 14 into which the end (corner) parts 15 of valves 12 are inserted (a variant of locking the valves without the use of adhesive tape).

To form the top, the end walls 1 and 5 are equipped with top located valves 16, and the side walls 3 and 7 are equipped with top located valves 17.

The top of the box can be formed by bending the valves from the walls towards each other (a classic option that requires the use of adhesive tape to fasten together those valves that are located outside the box). As an option, which is shown in Fig. 1, one valve 17 is made with petals 18 that can be bent inward (a line of weakened section breaks along the three-sided contour of the petal and the petal is folded inside the box along the inflection line on the fourth side), and the valves 16 are made with cuts 19, into which folding petals 18 are inserted When assembling the top, one valve 17 is first bent, then valves 16 bent towards each other are placed on top of it, and then another valve 17 is placed on top of the valves 16. In this case, the cuts 19 are located under the inflection line of the petals 18. After that, they press on the petals, tear them off from the valve body on three sides and by pressing the petals they are sunk into the cuts 19. The petal can have not only a rectangular or square shape in plan, but also a semicircle shape or a similar shape.

The fold line 20 of each lobe 18 is less than the width of the lobe measured along this line. And the cuts 19 are made in such a way that the central part of the cut allows the petal to easily enter this slot, and the side parts of the petal, sinking into the cut, are slightly deformed by the edge zones, and straighten under the valve and can no longer go out. This allows you to form the top of the box with quick assembly techniques and without the use of additional equipment and adhesive tape.

When forming the top, the flap 16, which does not carry the petals, is laid first by bending, and the flap 16, which carries the petals, is laid last. In this case, the locking connection due to the petals also allows you to fix the valve 17 without the petals under the pressure of the valves 16.

A feature of the bottom and top of the box for all examples of execution is that:

- the height of each valve (both upper and lower located) of each side wall, which is attached to the additional wall, in the direction from the inflection line of this valve from the side wall is less than the length of the side wall,

- and the height of each valve of each side wall, which is attached to the additional wall, in the direction from the inflection line of this valve from the side wall, is less than the length of the side wall.

This allows, when forming the top and bottom in the box, to exclude the butt joint of the free edges of the valves and to form openings 21. The fact is that the central zones of the top and bottom when using the box for lightweight products do not participate in the process of increasing the load capacity and maintaining the shape. Therefore, these zones can be weakened. Such a solution leads, despite the presence of additional walls as additions to the main walls, to a reduction in the consumption of corrugated cardboard from 5 to 10% while ensuring the strength of the box up to 33%. The dimensions of the openings 21 are determined so that the chips do not fall out of the box if the box is turned over or tilted. These openings can also be used as ventilation holes for gas exchange with the external environment, if the box will be used for storage and transportation of other products.

In the areas where the walls interface with the valves, especially with additional walls, the valves are made with beveled corners so that during the formation (assembly) of the box, the extra parts (corner parts) of the valves do not protrude beyond the dimensions of the box. This leads to the formation of triangular openings 22 in the corner zones, which can also be considered as ventilation, and due to which there is a reduction in the consumption of corrugated cardboard without affecting the strength of the box.

The second (Fig. 5 and 6) and third (Fig. 8 and 9) examples of execution in terms of the formation of an octagonal box repeat the design of the box according to the first example of execution (Fig. 1 and 2). In this regard, a detailed description of the structures of the boxes for these examples is not given.

The box for each of the execution examples is made with the function of turning into a show box (dispenser), that is, the box is laid out on a shelf in a store, and packages with products are not removed from it. To turn the box into a show box (dispenser), the following design is provided.

For the first example. On the surface of one side wall of the box according to the first embodiment (Figs. 1 and 2), for example, wall 3 located between two additional walls 2 and 4, part of the surface is limited by a closed line 23 of a weakened section to form a surface area to be removed when pressed on it . This line 23 stretched along the inflection line in the bottom formation zone, then goes with its ends along the inflection lines of the additional walls 2 and 4 associated with it and then continues (pos. 24) along the surface of its upper valve 17 used to form the top, line 23 ends at the free edge of this valve 17. In the lower part, in the bottom area, a push-through tongue 25 is formed on the line.

When the tongue 25 is pressed, it is pressed into the box, which forms an opening in the wall of the box, sufficient to stick a finger into it. With this finger, the torn-out part of the surface of the side wall 3 is grasped and pulled upwards. When this happens, the line of the weakened section is destroyed and part of the wall comes off, forming an opening in the wall 3. This part of the wall can be torn off from the valve. But if you pull further, the line 24 on the valve 17 breaks and the torn part is completely removed, forming a wide open opening in the box, through which you can easily and freely remove the bags with products (Fig. 4).

A version is possible when instead of a tongue on the line section in the zone or on the line of the weakened section 23 (near the bottom), not a tongue is made, but a hole for the finger so that it can capture the torn-out part of the wall 3.

For the second example (FIGS. 5 and 6). The construct of turning the box into a show box repeats the construct of the first example. But the tongue 25 is made elongated along the entire length of the section of the line 23 of the weakened section in the area along the bottom. This tongue is connected to the torn-out part of the wall 3 by a line of weakened section. When the tongue is pressed, it separates from the torn-out part of wall 3, then the tongue is bent inside the box, and only after that, by grabbing the palm of wall 3, the torn-out part is separated from this wall both on the area of wall 3 itself and on the area of its valve 17 (Fig. 7 ).

For the third example of execution. On the surface of one side wall 3, which is attached to additional walls 2 and 4 of smaller width, a line of weakened section 23 is made, stretched along the inflection line in the bottom formation zone with access to the surface of adjacent additional walls 2 and 4, along which this line is continued in side of the top of the box to the exit on the free edge of each additional wall (Fig. 8 and 9). Thus, the line of the weakened section passes through three adjacent walls.

In addition, fold lines 26 are applied on the tear-out section, extending from the tongue 25 (or holes instead of the tongue) to the corner points at the edges of the inflection line of the valve 17 from its side wall 3. That is, on the side wall inside the section of this wall, limited by the line of the weakened sections, fold lines are drawn, extending from a section of this line stretched along the bottom, to the corner points at the edges of the inflection line of the upper located valve from this side wall.

When you press the tongue 25, it is pressed inward, which makes it possible to stick a finger into the hole. The same is possible if a hole in wall 3 on line 23 is used instead of a push-through tab. Pulling on a part of the pull-out section causes it to tear off on wall 3, but the pull-out force is not enough to break the material along the weakened section line on additional walls 2 and 4 Therefore, pressure is applied to the sections along which the fold lines 26 pass, which leads to deformation of the torn-out section and facilitates its separation from the walls 2 and 4.

The bearing capacity of the box after the removal of a part of the side wall and a part of the valve (forming an opening) does not decrease, since it is determined by the vertically oriented position of the additional walls of the box, which are stiffening elements for the main walls of the box.

The present invention is industrially applicable and can be used as packaging for storage, transportation and display of products in the dispenser mode. EFFECT: invention makes it possible to organize access through openings for convenient and easy extraction of packages with the product individually. In this case, the box is obtained with increased bearing capacity due to the use of an octagonal wall configuration, in which part of the walls is made with a width less than the width of the remaining walls.
