Description

The invention relates to a container and considers, in particular, the construction of a cardboard packaging for carrying fast food products.

The term "fast food" in the framework of the claimed invention means fast food, fast food, fast food, food with reduced consumption and cooking times, with simplified or eliminated cutlery or off the table. The fast food category today includes those fast food products that are sold, for example, in the McDonald's or KFC restaurant chains. These products are sold ready-to-eat, that is, reheated, to be eaten at a table inside a restaurant, or packed in a large take-away bag. These foods include various types of hamburgers (sold in separate boxes or wrapped in paper), French fries (sold in open paper bags), hot dog (sold wrapped in paper or in a napkin), sandwiches (sold on plates or in bags or in separate boxes). A large selection of sauces is offered to these products (sold in small-sized plastic containers with openable film-lids), drinks (from juices to Coca-Cola, offered in cups with a lid with a hole for a straw), pies (sold in separate boxes) etc. If the customer intends to eat the purchased products in a restaurant, these products are served to him on a tray; if the customer takes out, then these products are put in one or two paper bags. As a result, one such bag can contain a hamburger box, a closed glass of a drink, an open bag of French fries, two or three jars of sauces, napkins and one or two other products (for example, pies in boxes).

So, there is a known box made of thin-sheet cardboard containing side walls and valves associated with them along the lower edge for assembling the bottom by the quick assembly method, as well as valves for assembling the upper part of the box, while the cavity of the box is used to accommodate fast food products (US 2021107695, B65D 5/02, B65D 5/42, B65D 5/46, B65D 5/54, publ. 04/15/2021).

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

The disadvantage of this solution is that in the cavity of the box the products lie in bulk on top of each other. In addition, the box does not have a load-bearing capacity and therefore cannot be used to carry a large amount of food due to the likelihood of the bottom opening.

The present invention is aimed at achieving a technical result consisting in ensuring the structural strength of the package and the preservation of its spatial shape by placing a reinforcing element in the form of a tray inside the box in the area of its bottom.

The specified technical result is achieved in that the packaging for fast food contains a four-valve box made of cardboard, made with handles for carrying and in the upper wall of which there are slots for accommodating flanged boxes for sauce or fast food products, and inside the box there is an insert in the form of an upside down a cardboard tray, with the side walls resting on the bottom of the box and from two opposite side walls of which parts of these walls made in the form of handles are bent, which are directed from the bottom along the adjacent side walls of the box, while at least one opening and dissection are made in the bottom wall of the insert to form nests for placing fast food products in them.

In this package, on all side walls of the box in the direction along the surface of the upper wall, a section is made in the form of a tape, bounded at the edges by lines of weakened strength, for dividing the box into lower and upper parts when aligning this tape, or a line of weakened strength is made to divide the box into a lower one and the top when breaking this line.

The specified technical result is achieved by the fact that in a box for packaging fast food, which is a four-valve box made of a cardboard sheet blank by bending its parts, which includes side walls connected in series through fold lines, each bent relative to an adjacent wall, while the indicated the side walls have flaps on one edge that are bent towards each other to form the bottom of this box, and on the other edge they have flaps bent toward each other to form a closed top of this box, the upper located flap of the first side wall is made with a longitudinal slot located in the central part of the valve and extending perpendicularly to the fold line of this valve relative to the side wall, and with a tongue on the free edge in the form of an extension of the valve in the direction from the fold line of this valve relative to the side wall, on the sides of this longitudinal slot in the valve body, through openings of a rectangular shape in plan, the upper located valve of the third side wall is made with a cut on the line of its inflection relative to the side wall, used to insert the tongue, the upper located valve of the first side wall, the upper located valves of the second and fourth side walls are each made lined up along the line bending of this valve relative to the side wall with H-shaped incisions, and on the free edge in the form of an extension of the valve in the direction from the fold line of this valve relative to the side wall, an extension of the valve made in the form of a handle is made, while in the assembled box the valve of the third wall is bent away from the wall and is located transversely to the side wall, the valves of the second and third side walls are located over the valve of the third side wall or a joint to its free edge and butt to each other with the arrangement of extensions in the form of handles transversely to the surface of the valves, and the valve of the first side wall is located above the valve pans of the second and fourth walls, its tongue is inserted into the cut of the valve of the third side wall, and the extensions in the form of a handle are brought out through the longitudinal slot, and the rectangular through holes in the plan of the valve of the first side wall are located opposite the H-shaped cuts of the docked valves of the second and fourth side walls.

In the box, on all side walls across their fold lines, a section is made in the form of a tape, bounded at the edges by lines of weakened strength to divide the box into lower and upper parts when aligning this tape, or on all side walls across their fold lines, a line of weakened strength is made for separation boxes to the lower and upper parts when this line is broken.

The specified technical result is also achieved by the fact that the insert for the box for packing fast food is a cardboard tray turned upside down, on two opposite side walls of which, from the line of bending of the walls relative to the bottom, cuts are made to form handles bent in the direction from the bottom, and on the bottom wall there are cut U-shaped in plan, circular in plan and linear in order to form nests for placing fast food products.

In the insert, the side walls in the corner zones can be fastened together.

In the insert, in at least part of the incisions across the incision line, incisions are made to form elastically bendable tongues.

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

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

fig. 7 is an example of an assembled insert.

According to the present invention, the design of the developed original packaging made of cardboard (for example, corrugated cardboard) is considered, which allows you to put individual fast food products into nests and protect these products from damage to their presentation and exclude the mixing of products and heating of cold products from nearby heated or heated products. Such packaging has practical application for cases of buying fast food products to go or to go.

In general, a fast food package comprises a four-valve carton box, provided with carrying handles and in the top wall of which slots are provided to accommodate flanged sauce boxes or similar fast food products.

Inside the box, there is an insert in the form of a cardboard tray turned upside down, with the side walls resting on the bottom of the box and from two opposite side walls of which parts of these walls made in the form of handles are bent, which are directed from the bottom and along the adjacent side walls of the box.

In the wall of the bottom of the insert, at least one opening and dissection are made to form nests for placing fast food products in them.

Thus, the insert placed inside the box is used for storing products such as a cup of coffee or a drink (juice or other soft drink), boxes of pies or pies wrapped in paper, for hamburgers, for fries, etc. The liner itself is laid in a box, in which the liner rests on the bottom of the box and on its side walls. To remove the liner, handles or ears are provided (cut-out parts of the side walls of the liner, which are located along the walls of the box). By opening the box and pulling on the handles or ears, you can remove the insert and use it as a tray. And on the top wall of the box itself, there are holes or openings into which you can insert portioned jars of sauces or similar products (packages with butter or jam) attached to hamburgers and / or fries. Traditionally, these portioned jars or packages or boxes are mini-trays, covered with a film, which, like a lid, is torn from the flange. When laying in the slots of the upper wall, the jar or box is launched into the opening and rests its flange on the wall of the upper part around the opening or opening. The slots in the top wall of the box may differ in the size of the opening and the shape of the opening, depending on the shape of the portion box with the product.

On all side walls of the box in the direction along the surface of the upper wall, a section can be made in the form of a tape, bounded at the edges by lines of weakened strength, to divide the box into lower and upper parts when aligning this tape, or a line of weakened strength can be made to divide the box into the lower and upper portions when this line is broken.

When using examples of the execution of the box with a tear-out strip section on the side walls or with a line of weakened strength located above the level of the bottom of the insert in the box, it becomes possible to separate the box between the lower part with the insert and the upper part with portioned products. Both portions, together with food items, can be viewed by the consumer as two fast food trays.

Below is an example of a specific execution of packaging for fast food.

Packaging for fast food products is a four-flap cardboard box, which has the shape of a parallelepiped and is formed by bending its parts along the fold lines from a sheet blank (Fig. 1) and an insert placed inside the box with support on its bottom and also made of a cardboard sheet blank (Fig. 6) by the method of bending its parts along the fold lines.

The sheet blank for the box (Fig. 1) has sequentially located and interconnected along the bend lines of the walls, located in the following sequence: side wall 1, end wall 2, side wall 3 and end wall 4. One of the extremely located side walls ends with an additional valve 5 used for gluing the side walls during assembly. This additional flap 5 can be located at the edge of the first side wall 1, as shown in FIG. 1 and at the last end wall 4.

The terms "side" and "end" walls of the box are used to understand the principle of bottom formation. Such terms can be used for a rectangular box in plan, when some side walls are made longer in length than 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 of all the walls in terms of dimensions.

To form the bottom, the side walls 1 and 3 from the side of the lower edge are made with valves 6 bent from the walls towards each other, and the end walls 2 and 4 are made with valves 7 bent from the walls towards each other. The bottom is formed by bending from the side walls of valves 6 and 7 towards each other.

In principle, the structure of the box bottom itself, which can be composed of four valves, is not essential for the essence of the claimed solution within the framework of the present invention. Depending on the shape of these valves, it is possible to execute the top by first laying the first two valves towards each other on opposite walls, and then the valves of the other two walls are placed on top of them, and these valves are connected with tape along the line of their contact. It is possible to design the bottom by first laying the first two valves towards each other on opposite walls, and then on top of them the valves of the other two walls are placed, which have a figured edge, due to which one of these valves engages with the other.

In the example of FIG. 1 shows the structure of the so-called quick assembly bottom. To do this, the valves 6 are made with an edge 9 that folds along the fold line 8, and the valves 7 are made of a trapezoidal shape also with an edge that folds along the fold line 10. the edge of which is located under another row of adjacent flap (Fig. 2 and 3). As examples of the bottom designs of valves that are similar in terms of the valve connection algorithm, one can consider the box designs described in RU 2323863, RU 2317926, RU 72678, WO 8200987, US 3790064, US 5664726, GB 2283726, DE 7039723, CN 106184961, CN 204750795.

Thus, a box with side walls and a bottom is obtained. In this box, the bottom is made using fast assembly technology. In this case, the bottom, once assembled from valves 6 and 7, is no longer disassembled and remains assembled.

The declared packaging refers to single-use packaging for fast food products. The general policy of network structures producing and selling fast food is to create low-price segment products. Accordingly, the packaging for such products is selected from this segment (wrapping paper, paper bags, boxes made of non-load-bearing cardboard, etc.), since the cost of packaging is included in the price of the product.

If a box is used for a set of fast food products, then it must be strong and retain its spatial shape in order to withstand the weight of the products and prevent them from being damaged when the shape of the box changes. This problem can be solved by making a box for stacking fast food products from thick cardboard or corrugated cardboard. But at the same time, the cost of such a box will seriously increase, at which it becomes unprofitable to buy it as a travel bag for food. A cheap box can be made of recycled thin-sheet cardboard, but with an increase in size, such a box loses its bearing capacity and is very easily deformed. In this case, the shape of the box can be deformed from a square or rectangular to a rhomboid in plan due to the fact that although the valves form the bottom, they are connected to each other, but not fastened. The walls of the box made of such cardboard, even under light pressure, lose their flatness due to the unstable shape of the bottom. But it is precisely such packaging that belongs to the category of cheap disposable packaging.

For such a box, it becomes important to ensure the shape and increase the bearing capacity, which can be obtained by strengthening the bottom zone of the box and creating additional support on the side walls. This function is implemented by an insert that fits inside the box (Fig. 6 and 7). The insert is a cardboard tray turned upside down 12, in which the side walls 13 and 14 are fastened together in the corner zones. In this case, the insert can be made of cardboard box.

The insert is placed inside the box with its side walls 13 and 14 resting on the bottom with its edges 15 in the area of the fold lines 16 of the valves 6 and 7 from the side walls 1-4 and with the support of the side walls of the tray 13 and 14 on the side walls 1-4 of the box. When using thin-sheet cardboard of the category of boxboard and when forming the bottom by the method of quick assembly, the least strong part of the bottom of the box is located in the central zone of the bottom, and the maximum strength of the bottom is located in the zone close to the inflection lines of 16 valves relative to their side walls. When placing the insert, its side walls rest on the bottom precisely in this zone at the fold lines 16. Therefore, the strength of the central zone of the bottom is not used in this case. Since the walls of the tray rest on the side walls of the box, the zones are reinforced by the right angle of the box, which increases the strength of the box and its bearing capacity. The liner becomes an element for forming the rigidity of the bottom zone of the box and at the same time is an element for maintaining the side walls of the box in terms of reducing their ability to bend.

The liner is also used as a lodgment for placing fast food products. For this, the bottom wall is made U-shaped incisions 17 in the plan, 18 circular incisions in the plan and 19 linear incisions to form nests for placing fast food products. Since it is not known exactly what size the product will be purchased, all the cuts are made with the possibility of stacking the product in a fairly wide range of its standard sizes. For this, in at least part of the incisions across the incision line, incisions 20 are made to form elastically bendable tongues 21 or petals. When placing, for example, a bag of French fries in a linear cut, the bag deflects the tabs 21 (petals) inside the insert, and these tabs support the bag in a vertically oriented position due to the elasticity of the paperboard material of the tabs. The length of the incisions 20 determines what size the bag can be inserted into the incision. A similar technique is used for cutting a round shape for installing beverage cups. A product such as a pie in a box fits into a U-shaped incision 17. When laying, the tongue 21 of this cut bends and then resiliently abuts against the box of the pie, positioning the box pressed against the wall of the bottom. The shape and size of the incisions produced by these incisions and their size can vary and vary in a wide range of shapes and sizes of manufactured products classified as fast food. The concretization of the forms of dissection by him of their sizes is not essential for solving the problem of increasing the strength and maintaining the shape of the box.

The shape retention of a box made of thin-sheet cardboard directly depends on the area and dimensions of the side walls. The less they are, the greater the deflection stiffness of the side walls. The position of the wall of the bottom of the liner along the height of the side walls of the box divides the area of each side wall of the box into two parts, each of which acquires an increase in rigidity to deflections due to a decrease in its area in relation to the total area of the side wall of the box. The height of the side walls of the insert is also determined on the basis that the position of the edge walls of the incisions should be close to the center of gravity of the products placed in the nests, in particular, in relation to the glass with the drink. For this reason, the wall of the bottom of the liner tray is located no higher than the middle of the height of the side wall of the box.

In the insert, on two opposite side walls (13 or 14, Figs. 6 and 7) from the fold line of these walls relative to the bottom, figured cuts are made to form handles 22 bent away from the bottom. After assembling the box, an insert is placed in it. When laying, the handles are separated from the side walls and bent in the direction from the bottom, and then the liner is placed in the box, and the handles are placed raised along the side walls of the box. These handles are subsequently used so that by pulling on them, you can pull the insert out of the box and use the insert with the products placed on it as a table with food or a tray.

The structural features of the fastening of the side walls of the insert tray are not considered in detail as not related to the essence of the claimed solution. It is important that these side walls are fastened together by any known technique. The fastening of the side walls allows to increase the strength of the tray due to the formation of reinforced zones of right angles.

After laying the liner inside the box, the upper part of the box is formed (Figs. 1-3).

The side walls 1-4 of the box from the top side are made with valves 23-26 (Fig. 1), the fold of which forms the closure of the box with the simultaneous formation of handles for carrying the box.

The upper located flap 23 of the first side wall 1 is made with a longitudinal slot 27 located in the central part of this flap and extending perpendicular to the fold line of this flap relative to the side wall 1, and with a tongue 28 at the free edge in the form of a flap extension in the direction from the fold line of this flap relative to the side wall. In this case, on the sides of this longitudinal slot 27 in the valve body, through holes 29 are rectangular in plan, arranged in a row.

The upper located flap 24 of the third side wall 3 is made with a cut 30 on the line of its fold relative to the side wall 3, used to insert the tongue 28, the upper located flap 23 of the first side wall. In the assembled box, the valve 24 of the third wall is bent from the wall and located transversely to the side wall.

And the upper located valves 25 and 16, respectively, of the second 2 and fourth 4 of the side walls are made the same. In this case, each flap 25 or 26 is made with H-shaped incisions 31 lined up along the fold line of this flap relative to the side wall. Since the incision is H-shaped, two elastic tabs 32 are formed in such a seat. The incisions 31 are arranged in a row along the fold line of the flap relative to the side wall.

On the free edge of each flap 25 or 26, in the form of a flap extension in the direction from the fold line of this flap relative to the side wall, a flap extension in the form of a handle 33 is made. These handle extensions can be folded away from the flap body 25 or 26 along the fold line.

The upper part of the box is formed as follows (Figs. 2 and 3). In this case, the top of the box can be laid in several ways.

When laying without glue, the valve 25 of the second and the valve 16 of the third side walls are located over the valve 24 of the third side wall or a joint to its free edge and butt to each other with the arrangement of extensions in the form of handles 33 transversely to the surface of these valves. The flap 23 of the first side wall is located over the flaps of the second and fourth walls, its tongue 28 is inserted into the cut of the flap 24 of the third side wall, and the extensions in the form of the handles are brought out through the longitudinal slot 27 outward.

As a development of this example, first the second flap 25 and the third side flap 16 are folded over and abutted relative to each other with handle extensions 33 transverse to the surface of these flaps. Then a valve 14 of the third side wall is laid on top of them. A The first side wall valve 23 is positioned over the second and fourth wall valves and over the valve 14. A tongue 28 is inserted into the cut of the third side wall valve 24 and the handle-shaped extensions are pulled out through the longitudinal slot 27.

In the glue method of forming the top of the box, the flaps 25 and 16 of the second and third side walls are first bent and positioned end-to-end with respect to each other with the arrangement of extensions in the form of handles 33 transverse to the surface of these flaps. Then the valve 14 of the third side wall is laid on top of them and glued to these valves. And the valve 23 of the first side wall is placed over the valves of the second and fourth walls and over the valve 14 and glued to them. The tongue 28 is then inserted into the cut of the third side wall flap 24 and the handle-shaped extensions are pulled out through the longitudinal slot 27.

When forming the top of the box, the through holes of a rectangular shape in the plan of the valve of the first side wall should be located opposite the H-shaped cuts of the docked valves of the second and fourth side walls. This makes it possible to form a reliable nest for installing flanged cans. Each such nest is used to accommodate portioned packs or jars such as sauce jars. When placed in such a socket, the jar pushes the tongues 32 into the box and sits with its flange on the surface of the valve 23. And the tongues 32 resiliently hold the jars in the seats. Such jars or boxes with flanges (for example, for sauces) are made of small height and with rounding at the bottom of the transition of the bottom to the side walls. In this regard, it is important that in the nest in the box, the walls of the valves fit tightly to each other and do not choose the depth of planting of the low-rise box. Then the elastically squeezed tongues will press the box against the walls of the nest and hold it in this position. If there are gaps between the walls of the valves, the landing depth in the box will be increased and during laying the box can be pushed out by the elastic tongues 32 due to the fact that these tongues will contact the box in the rounding zone of its bottom.

A feature of the claimed packaging for fast food is that on all side walls, across their fold lines, there is a section 34 in the form of a tape, bounded along the edges by lines of weakened strength for dividing the box into lower and upper parts when aligning this tape. Instead of such a tape, a line of weakened strength can be made on all side walls across their fold lines to separate the box into a lower and an upper part when this line breaks. This allows you to divide the box into a lower part, in which the insert with food is located, and into an upper part, in which jars for sauces and similar portioned products are placed. When the box is split, the upper and lower parts retain their strength and shape.
