Abstract

The utility model is a package for a portioned food product, mainly a baked product, such as a round pie segment, intended for use directly from the package. The package consists of one sheet blank with fold lines made on it, separating the side walls of the package, which are isosceles triangles converging at one point. Two side walls, which are opposite after assembly of the package, have extensions in the form of valves, and one of the side walls has an extension in the form of a cover having grooves along the edges of the fold to close after assembly of the package in order to prevent the food product from falling out of the package. The packaging is made of unilateral coated paperboard delivered in the form of a flat blank with gluing along the side flap and designed for quick assembly before forming a bulk packaging.

Description

The utility model relates to packaging for a portioned food product intended for consumption directly from the packaging. The portioned food product is understood to mean food products that can be cold or hot portions, such as a segment of a round cake, pizza, etc., for which the claimed packaging is intended.

The packaging is made of single-coated coated paperboard with a square meter mass of 240-270 grams, supplied in the form of a flat blank with gluing along the side flap, and designed for quick assembly before forming a bulk packaging. The cardboard blank of the claimed packaging consists of one part.

Known packaging made of cardboard, including a side girdle with two longitudinal sides connected by two extreme sides, made in the form of a curve and / or with a fold for organizing the storage space of the food product, and a shell. The shell has a bottom zone and a cover zone, each of which is fixed on a different longitudinal side, and a side curb zone, fixed on the extreme sides of the girdle so as to close the food product in the storage space. The shell is fixed with the possibility of removal on the extreme sides (patent RU 2541941 C2, IPC B65D 85/76, published 02/20/2015). Such packaging is intended to be used directly from the packaging of foods such as butter, chocolate, paste, etc.

The disadvantage of this design is the compilation of the package from two different parts of the workpiece, one of which forms a girdle, and the other part forms a shell, and the inability to manually assemble the package immediately before putting the food product into the storage space. The packaging was made without applying a protective polymer layer on the side of contact with the food product, which leads to oil leakage and the appearance of greasy spots on the cardboard packaging, leading to contamination of the consumer's hands when using the food product directly from the package. Placing a food product in such packaging involves costly production using automated production lines. Transportation, warehousing and storage of such packaging in assembled form leads to the unjustified use of large areas and to a possible violation of the integrity of the packaging.

Also known packaging, selected as a prototype for the proposed technical solution, made of cardboard and intended for packaging and storage of various goods. The package consists of one sheet blank containing a box with a hinged lid, the box having a bottom and front, side and rear walls with valves separated from the bottom by bending lines, bent inside the box along the bending lines; there are perforation lines on the valves. The packaging lid is made of triangular sections separated from each other by inflection lines in the form of isosceles triangles with a common apex and with a side valve in one of the triangular sections. After assembly operations, the package is a pyramid (patent RU 23430 U1, IPC B65D 5/02, published June 20, 2002).

Compared with the first analogue, this package, which is closer to the claimed technical solution, is made of one sheet blank, has valves, inflection and perforation lines for assembling the package, can be transported, stored and stored in the form of a flat blank and allows you to assemble the package not only with the help of automated equipment, but also manually immediately before putting the goods into the package.

The disadvantage of the closest analogue is the difficulty of connecting the lid with the side walls when collecting the package and the low reliability of fastening the lid with the side walls in the assembled state, which is expressed in the possible opening of the package when it is turned over under the influence of the weight of the goods packed into it. This is because the valves can be squeezed out from the inside when moving the packaged goods, for example, when transporting or turning the package around, when the valves are at the bottom of the package and they are affected by the weight of the packaged goods. This drawback makes packaging difficult. The packaging was made without applying a protective polymer layer from the side of contact with the product, including the food product, which leads to the appearance of greasy stains on the cardboard packaging, leading to contamination of the consumer's hands when using the food product directly from the package.

The disadvantage of packaging is also the complexity of execution, which entails the use of more complex equipment such as a die cutting machine with a large number of cutting, scoring and perforating rulers to cut the packaging blank, which leads to an increase in the consumption of material (cardboard) and an increase in the cost of production of such packaging. The complexity of the packaging makes it impossible to quickly assemble the packaging manually immediately before laying the goods, which is important in the conditions of use of the packaging in places of manufacture and sale of baked goods such as round pie, pizza, etc.

The technical result of the claimed utility model is to ensure the convenience of using a portioned food product directly from the package due to the presence of perforation lines on the surface of the package, facilitating the phased separation of parts of the package.

The technical result is achieved by applying lines of weakened strength (perforation lines) on the side walls and the side valve of the package so that after it is collected until the bulk packaging is formed, the lines lie in the same plane at an equal distance from each other, dividing the side surface of the package into three equal lengths parts, facilitating the phased separation of packaging parts.

The utility model is illustrated by drawings, where in FIG. 1 shows a scan of the packaging blank.

The package consists of side walls 1, 2, 3 and 4, separated by fold lines 5, extensions 6 in the form of valves, side valve 7, cover 8 with valve 9 and additional elements 10, 11 and 12 located on the side walls of the package. There are notches on the cover 13. On the side walls and side valve there are lines of weakened strength (perforation lines) 14, 15 and 16.

For the manufacture of reamers of the claimed packaging, lamellar (coated with a polymer layer) cardboard sheets of 620 × 940 mm in size are used for unilateral coating on the intended outside of the packaging. The coated layer provides brightness, clarity and saturation of color images printed on the side surface and the lid of the package. Cardboard with a thickness of 0.4 mm and a polymer layer thickness of 5-7 microns, applied by extrusion, is used to prevent warping of cardboard sheets during lamination. The presence of a polymer layer on the alleged inner surface of the package contributes to the grease-tightness of the package material and does not increase the cost of the package itself, since the extrusion method of applying the polymer involves the use of fairly cheap raw materials - polymer granules.

On a sheet of cardboard there are 10 pieces of packaging scans.

The next operation on the sheets of cardboard on the coated side is the four-color offset printing of the image (printing 4 + 0). For printing, inks with a slight smell of their own are used, certified for the production of food packaging. It is possible to use paints based on polyvinyl butyral, which is a binder that does not hold paints drying inhibitors (ethoxy or methoxy propanol). The concentration of residual solvents in the ink film does not exceed 5 mg per square meter.

The next operation is the cutting die sweep of blanks on a die-cutting machine with the simultaneous application of creasing and perforation lines. A die is used for die cutting, on which the following types of lines are installed:

- cutting rulers (it is possible to use rulers with a straight chamfer and one-sided or double-sided edges; the use of knives with an edge made by grinding will reduce dust and improve the sanitary and hygienic characteristics of packaging);

- scoring rulers (standard edge; the width of the ruler is determined empirically, depending on the thickness of the cardboard);

- perforating rulers.

Packaging is assembled and used as follows.

When collecting the development of the workpiece into the package, the side walls 1-4 are bent along the fold lines 5, the adhesive layer is applied to the side valve 7 and glued to the side wall 1.

Then, glued blanks are stored, brought to a flat state by folding along two opposite fold lines 5, into boxes and transported to the places of intended use, namely, to the places of production and sale of baked goods, such as a cafe and restaurant.

The transition from the state of the sheet blank to the state of the blank glued along the side valve is technologically understandable and does not require a detailed description, since it is not used in places of production and sale of baked goods, such as cafes and restaurants, in the conditions of which the claimed packaging will be applied.

However, it should be noted that this operation is carried out by bending the side walls 1-4 along the fold lines 5, applying an adhesive layer to the side valve 7 and gluing it to the side wall 1. Gluing occurs using glue based on PVA dispersion recommended for use in food industry, which provides fast bonding, does not adversely affect the food product and does not interact with it.

This operation can be carried out on equipment built into the line with the equipment used in previous operations, in the automatic mode in the conditions of production of cardboard packaging blanks.

At the point of sale of baked goods, the package is filled with a ready-to-eat food product by placing the food product (pie or pizza segment) in the space formed by the side walls of the package. At this stage, the packaging on the outside is a pyramid.

The packaging is assembled. Extensions 6 in the form of valves are bent along the fold lines 5 inside the package. The lid of the package is assembled into a lock connection due to the fold line 5 between the lid 8 and the valve of the lid 9 and the slots 13, ensuring the rigidity of the package design with the food inside and the reliability of the fastening of the package.

The package is opened in stages using additional elements 10, 11 and 12, starting with the narrowest part of the package. Holding the package with one hand, pull on the additional element 10 to separate part of the package along the perforation line 14. At the same time, the user consumes the part of the food product that became available after separation of the part of the package. Then, pull on the additional element 11 to separate the next part of the package along the perforation line 15. The last part of the package is revealed in its widest part using the additional element 12 along the perforation line 16.

The step-by-step separation and removal of parts of the packaging contributes to the convenience of further consumption of the food product.

The design of the box is easy to manufacture and disclose.

Owners of cafes and restaurants (such as fast-food restaurants) can use the proposed packaging as an advertising tool to attract customers.

Warehousing packages in a flat state until they are used allows you to save work space.

The utility model is a simple, sufficiently strong and rigid structure with reliable fastening, easy to assemble and convenient to use for servings of food products, in particular a baked product such as a segment of a round pie or pizza.
