Description

The utility model relates to technical solutions in the field of containers and packaging and can be used to create packaging made from flat blanks separated by folding lines and used, in particular, for food products of cafes and fast-food restaurants selling takeaways.

Known folding packaging [BS 39575, W, V65E 5/36, 08/10/2004], formed from a flat blank separated by folding lines and containing four side walls, while the edge side walls are interconnected by means of, mainly, an adhesive layer, for which one of the edge side walls is provided with a side valve, and a closable base formed by connected to the corresponding side wall and arranged alternately by two internal valves and two closing valves made in the form of a trapezoid, the larger base of which oh located near the corresponding side wall, with each closing valve located outside the corresponding internal valve and connected to it, mainly by gluing, and each of the closing valves is equipped with a first Y-shaped cutout located in the middle part at the smaller base, the second Y- a neckline located in the lower part of its lateral side, and an additional fold line connecting the vertices of the first and second U-shaped cuts, and the side walls are made in the form of a trapezoid.

The disadvantage of this package is the relatively narrow functionality, since it is folded designed to accommodate mainly one product, which narrows the scope of its application.

Foldable packaging is also known [1Sh 70868, Sh, V65E 5/00, 01/20/2000], made of a flat single workpiece having horizontal and vertical arcuate folding lines folded along these lines into a hollow body containing two front walls, a lid that is the continuation of the front walls in the form of valves, one of which is laid on top of the other valve, the bottom, which is the continuation of the front walls in the form of valves, one of which is laid on top of the other valve, two side walls made with extensions in the form of valves laid under the valve the cover and the bottom, moreover, the vertical fold lines of the front walls in the direction from the bottom to the cover are made on the first half of the length of the fold line arcuately concave, and on the second half of the fold line - arcuately convex to form a wavy surface of the front and side walls, with horizontal lines the folds of the front walls for bending the valves are made of the same length, and one of the side walls is made of two parts, each of which is connected along the arcuate fold line with the corresponding front wall, and Irina one part of the side wall is wider than the other part of the wall for connecting these parts together overlapping.

The disadvantage of this technical solution is the relatively low performance due to the complexity of the design, and relatively insufficient strength, which is manifested when using relatively heavy products, for example, containers with drinks.

In addition, a folding package is known [KI 81769, Ш, В65В 5/36, 03/27/2009], which contains a closable housing made of a flat unit blank, divided by inflection lines into elements forming the components of the housing, including a cover, a bottom, a front and back walls made with rectangular sections extending downward partially overlapping each other, the lower halves of the front and rear walls of the package being conical with slightly concave side edges, and the upper halves of these walls are made p expanding with curved edges around their perimeter, while the front wall is made of two parts superimposed on each other and located on the workpiece on both sides of the back wall of the packaging, on the inside of which a rectangular section extending downward is made, and the upper part of the inner part bounded above by an oval edge, below - by a symmetrical oval fold line with slots along it to form a lid, fixed on the inner surface of the back wall of the package, on the connection zones its wall with corresponding portions of the front walls are rectilinear fold lines throughout the length of the package and protruding from it in different directions fold lines which are side edges of the lower halves and extending approximately to the middle of the length of the package, and the front and rear walls of the housing applied graphics.

The disadvantage of this package is the relatively narrow functionality, since it is folded designed to accommodate mainly one product, which narrows the scope of its application. In addition, it has a relatively insufficient strength, which is manifested when using relatively heavy products. An attempt to use a thicker and less flexible workpiece material leads to excessive material consumption.

Another well-known technical solution is folding packaging [ES 175128, Sh, V65V 5/36, 11/21/2017] made of a flat blank of food packaging material, mainly food cardboard, divided by fold lines into the elements forming the package, which are a rectangular base formed by two superimposed lower and upper layers of food packaging material from which a flat blank is made, two packets, the bases of which are in the form of two segments of a circle, while forming chords of two The circle segments are adjacent to each other, located on opposite sides of the packets, and the circle segments themselves form an element in the form of a petal supporting the arched shape of the base due to deformation, moreover, a fastening element is made in the upper part of the contacting sides of the packets, consisting of a locking valve on one bag and slots for the valve-clamp on another bag with the possibility of the formation of a lock connection.

The features of this technical solution is that when folding packaging is made from a flat blank of food packaging material, mainly food cardboard, it is glued into the pipe by overlapping the opposite sides using an adhesive joint, and then they give the pipe a flat shape so that the adhesive seam is in the middle, while the two glued sides of the flat blank are straight and mutually parallel, and the other two sides are concave, with a flat each billet is divided by pre-prepared folding lines into three parts - two equal parts of the packages, and between them the part of the base, and the width of the base part between the folding lines corresponds to twice the height of the circle segment, technological holes are made at the intersection of these lines with the lines bounding the circle segments , and all prepared fold lines crossing the glue line have

wedge-shaped cuts for the width of the seam made on the inner layer of the cardboard forming the adhesive seam.

In addition, in this collapsible package, in the upper parts of the adjacent lateral sides of the bags, above the fastening element, holes are formed forming handles for transferring the package, in the upper part of the bag with a slot for locking connection, two horizontal slots are made on each side to connect them by tearing the gap between them and bending the sides inward for placement in a bag, or a glass, or a bottle with a drink, fixing hooks are made on the adjoining inner sides of the bags, and on the main Inania - fastening slots with the possibility of fastening two additional modules for food products, placed between opposite extreme sections of the sides of the packages on opposite sides of the transfer handle, three mounting holes are made in the upper parts of the packages with the possibility of installing two lids in them, one for each package, three mounting holes are made with the possibility of installing additional modules in them, additional modules for food products are made with the possibility of placing containers for n foodstuffs, additional modules for food products made with the possibility of placing containers for sauce in them, additional modules for food products made with the possibility of placing containers for dessert in them.

The disadvantage of this technical solution is the relatively low stability of the folding package when filling it with products if it is placed for the main use on the horizontal surface of the table or counter.

This drawback is largely eliminated in folding packaging, which is closest in technical essence to the proposed one [1Sh 179706, Sh, V65R5 / 36, 05.22.2018] and which

 made of a flat billet of food packaging material, mainly food cardboard, divided by fold lines into the elements forming the package, which are a rectangular base formed by two superimposed lower and upper layers of food packaging material from which the flat billet is made, two packages, the bases of which are in the form of two segments of a circle, while the chords of the two segments of the circle are adjacent to each other, being on opposite sides of the packets, and the seg The circle elements form an element in the form of a petal, supporting the arched shape of the base due to deformation, moreover, in the upper part of the contacting sides of the packages, a fastening element is made, consisting of a locking valve on one package and slots for a locking valve on another package with the possibility of forming a lock connection , on the lower layer of food packaging material along the edges of the bases of each of the packages corresponding to the outer of each two segments of the circle forming the bases, valves in the form of legs are made, lines from iba lie at the outer edge element in the form of a lobe, and the top layer of the food packaging material in front of each of the valves in the form of legs formed wedge valves for closing openings formed by folding the package by folding in the flaps form the legs.

A feature of the closest technical solution is that in the upper part of the bags there are small and large swing-away valves with horizontal slots for placing containers with products, and also that the small and large valves are made by tear-off perforation, a slot for engaging in the middle slot of the small valve, on the small valve a slot is made to hold the product in a small package, on the side of the large valve in the base of the bags

 a round slot with a spike was made to hold a disposable glass with a drink, and on the upper side of one of the two packages two valves were made - a food holder in the form of flat pieces.

In addition, a hole is provided in the fastening element for carrying the food package on the finger. This, on the one hand, leads to an increase in the size of the fastener, and, on the other hand, complicates the product and causes great inconvenience in use.

The disadvantage of this technical solution is the relatively high complexity, relatively large dimensions and relatively large material consumption, caused by the fact that, in the upper part of the contacting sides of the bags, a hole for carrying the package is made, as well as a fastening element consisting of a locking valve on one bag and a slot for valve-clamp on another bag with the possibility of forming a lock connection. In the practical implementation of such a folding package, the indicated execution in the upper part of the fastener element packages leads to a significant increase in product dimensions in height, excessive consumption of materials and complicates the product, since a locking connection is used in the form of a locking valve on one bag and slots for a locking valve on another In the package and when using the product, it is necessary to carry out relatively complex manipulations to realize the castle connection. The latter complicates the product and its use.

In addition, wedge-shaped valves are made on the upper layer of the food packaging material opposite each of the legs-shaped valves to close the holes formed when the package is folded during folding of the legs-shaped valves. The wedge-shaped form of the valves leads to gearing and uneven formation of the package. This also complicates the product and requires increased accuracy in the manufacture and assembly of folding packaging.

In addition, it should be noted that in the long valve the glasses are placed unreliably and at an angle, because the valve is attached to only one of the bags. In a short flap, it is possible to place only a jar of sauce. All this affects the performance of the product.

The problem that is solved in the proposed utility model is the creation of a folding package formed of flat blanks separated by folding lines, used, in particular, for food products of cafes and fast-food restaurants, in particular, those that take away and / or through the car distribution window, and intended for consumption of food and drinks while standing, on the go or in a car and having smaller dimensions, less material consumption and ease of putting into working condition, which ultimately leads to This leads to a decrease in manufacturing complexity and to an increase in usability.

The required technical result is to reduce the dimensions, material consumption and complexity, which leads to an increase in simplicity and convenience of putting into working condition, as well as manufacturability (mass) of production and, as a result, to reduce the price of the product, including through the use of machine gluing .

The problem is solved, and the required technical result is achieved by the fact that the folding package is made of a flat blank of food packaging material, mainly food cardboard, divided by fold lines into the elements forming the package, which are the base in the form of an ellipse truncated at the tops, formed by two superimposed one on top of the other with the lower and upper layers of the food packaging material from which the flat blank is made, two packets, the bases of which are in the form of two circle segments, forming an element in the form of a petal, supporting, due to deformation, the vaulted shape of the base, and one of which is solid and the other is glued from two parts, in which wave-shaped slots are made at the edges, moreover, an attachment element is made in the upper part of the contacting sides of the packages, on the lower layer food packaging material at the edges of the bases of each of the packages corresponding to the outer of each two segments of the circle forming the base, made valves in the form of legs, the folding lines of which lie on the outer border of the element in in the form of a petal, according to a utility model, the fastening element in the upper part of the touching sides of the packages is made in the form of a cutout in one contacting side of the packages and a valve on the other contacting side of the packages, made with the possibility of bending and fixing in this cutout, and in the upper parts of the packages there is a longitudinal section without its execution on the adjacent sections of the packages for the formation of narrow handles with the possibility of their use in the transfer of products.

Foldable packaging is made of a flat blank of food packaging material, mainly food cardboard, divided by fold lines into the elements forming the package, which are the base 1 in the form of an ellipse truncated at the vertices, formed by two superimposed lower and upper layers of food packaging material, which made a flat workpiece, two packages 2 (figure 1), the bases of which are in the form of two segments of a circle, one of which is solid 3, the other 4 - glued in two parts, while in the segment 4 circles at the edges are made wave-shaped slots 5, these segments are adjacent to opposite segments 3 of the circle in the area of the straight segment 6 with wave-shaped slots 5, the segments of the circles 3 and 4 themselves form an element 7 in the form of a petal, supporting, due to deformation, the vaulted shape of the base (Fig. 4), on the lower layer of the food packaging material along the edges of the bases of each of the packages corresponding to the segments 3 of the circle forming the bases, valves 8 are made in the form of legs, the folding lines of which lie on the segments 3 of the circle (Fig. 5), four valves 9, overlapping the openings from the valves 8 in the form of legs, are limited by wave-shaped slots 5 on the upper layer of the food packaging material of the packages, these valves 9 are glued to the inner side of the lower layer of cardboard in the region of rounded peaks, and are located inside the element 7 in the form a petal, while in the upper part of the contacting sides of the packages, a fastening element is made in the form of a cutout 10 in one contacting side of the packages and a valve 11 on the other contacting side of the packages, configured to bending and fixing in this cutout, on the sides on the base 1 of the product between the packages 2, through holes 12 are made with a hook 13 for holding the cups, technological corner 14 and axial 15 holes are also made on the base, additional cuts 16 are made on the outer sides of the packages from above the formation of holding short 17 and long 18 strip elements with the possibility of connecting these elements, made on different packages, in the side holders 19 for glasses (Fig. 6, 9).

In addition, in the upper parts of the bags, above the strip elements 17 and 18, there is a longitudinal section 20 without performing it on the adjacent sections of the bags to form narrow handles 21 with the possibility of their use in the transfer of products. At the base of the handles 21 there is a thickening 22 of them, on which swept elements 23 are applied, made using preliminary preparation of a fold (creasing), ensuring an even position of the handles after their separation (Fig. 6).

In addition, on the long strip element 18 there is an anchor element 24 in the form of a semicircle, on the short strip 17 there is a drop-shaped counter-mounting hole 25 with the possibility of fastening strip elements 17 and 18 located on different packages by turning the long element 18 around the axis with the latter horizontal position, placing the anchor element 24 inside the mounting hole 25 and return the long element 18 to its original vertical position (Fig. 9).

In addition, on the inner walls of the packages made additional mounting holes 26 - in order to form retaining elements for cups of smaller diameter (figure 3).

Striped elements 17 and 18 in a connected form provide the formation of a semi-finished folding package in the form of a vaulted element (Fig. 10) for overhead storage. At the bases of the strip elements 17 and 18, by preliminary preparation of the bend (creasing), a swept element 27 is made, which ensures an even arrangement of the connected strip elements 17 and 18 with overhead storage. Also, the connected strip elements 17 and 18, when the packaging is brought into operation from the semi-finished product, spontaneously transform into holders 19 for glasses (Fig. 9)

In addition, the holes 12 with a hook 13 for holding the glasses, located on the base between the packages, are implemented with the possibility of tearing the hook 13 on the top layer of the cardboard and bending it outward along the arc 28 of the pre-formed folding. This allows you to place in the holders not only cups, but bottles of water or, for example, hot dogs (Fig. 9).

Sections 16 and 20, openings 12 with a hook 13, and also slots 5, have thin technological jumpers (bridges) 29 that reduce the possibility of engaging glued workpieces when using automatic bonding. When the package is brought into operation, these jumpers are easily torn (Fig. 6).

The package is glued by applying glue on the sections 30 of the axial seam, at the tops 31 of the valves 9 and the formation of the workpiece along the fold lines (Fig. 6).

The longitudinal lines of the fold 32, the segments of the circle 3, the segments 6 and the arc 33 of the petal elements 7 are performed using continuous perforation, which facilitates bringing the packaging into working condition (Fig.6, 7, 8).

Foldable packaging is used as follows. A flat blank for folding packaging (Fig. 3) is performed mainly from a sheet of food cardboard. The workpiece is transformed into a package by folding along the longitudinal lines of the fold 32 and applying glue at the gluing points.

The folding package has a fastening element in the upper part of the contacting sides of the bags 2, made in the form of a cutout 10 in one contacting side of the bags and a valve 11 on the other contacting side of the bags, made with the possibility of bending and fixing in the neckline 10. This fastening greatly simplifies folding packaging , increases the reliability of the connection, reduces the size and material consumption of the product. The implementation in this form of means of transferring folding packaging with products also simplifies folding packaging and reduces the dimensions and material consumption of the product. In addition, in a folding package along the edges of the bases of each of the packages 2, corresponding to the outer of each two segments of the circle forming the bases, valves 8 are made in the form of legs, the folding lines of which lie on the outer border of the element 7 in the form of a petal, and also valves 9 in the form of waves connected with glue to the inner surface of the opposite wall of the package. This ensures the stability of the product when it is installed on a horizontal surface.

On the outer sides of the bags 2, a cut 16 was made to form strip elements 17 and 18, providing the formation of a semi-finished folding package in the form of a vaulted element for overhead storage (Fig. 10) before use, and after putting it into working condition - forming holders 19 for glasses.

Additionally, additional cuts 20 may be made over cuts 16 with the possibility of forming folding handles 21,

Bringing the packaging into working condition is possible manually (Fig. 11), or using baking tongs (Fig. 12), which ensures that the packaging meets sanitary and epidemiological requirements.

In both cases, the sequence of actions is as follows:

1. The package is held in one hand and bent in the middle along the axial holes 15, the fingers of the other hand or forceps are placed in the packages 2 (Figs. 11a, 12a)

2. The bags are pushed apart with one hand (forceps) inward, increasing in width, while the fingers of the other hand gently press the center of the base 1 from the bottom (Fig. 11b, 12b), as a result of which the packets 2 and the vaulted position of the base are formed (Fig. 11c , 12c).

3. Fingers of a free hand (forceps) grasp the valve 11, which is then tilted sideways into the neckline 10, bent into the bag and fixed in the neckline 10 (Fig. 11g, 12d.).

Thus, in the proposed collapsible packaging, the required technical result is achieved, which consists in reducing dimensions, material consumption and complexity, since the fastening element in the upper part of the touching sides of the bags is made in the form of a cutout in one contacting side of the bags and a valve on the other contacting side of the bags bending and fixing in this cutout, and in the upper parts of the packages there is a longitudinal section without its execution on the contacting sections of the packages to form narrow handle with the possibility of their use in the transfer of products.
