Description

The utility model relates to the field of packaging and may find application as a container for eggs, used for transportation, storage and retail for the sale of goods.

Known egg packaging, comprising a tubercular pad-substrate of a honeycomb design with hollow separation stops, into the cells of which eggs are laid, as well as a removable lid, and closed in assembled form by a heat-shrink film sheath, the lid is made of a flat reamer bent along the lines fold with the formation of at least two opposite side walls, the edges of which have serrated protrusions, the shape of which allows them to be fixed in the cells of the substrate, the lid has a window on the upper plane, chopped parts which are bent inwardly to form ribs having a serrated projections, the shape of which enables them to lock into substrate cells (RU 71640, B65D 85/32, publ. 20.03.2008).

The use of the cover allowed its surface to be used as a field for special information about the product and the manufacturer.

The disadvantage of this solution is the lack of strength of the cover in its central part. The cover, as a rule, is made of thin cardboard up to 3 mm thick and in the central part has a sufficiently large area equal to the area of the tuberous lining. Such a cover does not hold the load, and therefore a hole is made in its middle zone, the edges of which in the form of serrated protrusions are lowered down and located in the cells, acting as stiffeners. In fact, these are not stiffeners, but props, which together provide the ability to keep the flat part of the lid away from the eggs. Such supports still somehow from the deflection hold the upper part of the lid and then due to the fact that the package is wrapped with shrink film. When one or more supports are broken, the entire lid becomes unstable.

The disadvantages due to the design of the lid are overcome in the well-known egg packaging, containing a rectangular tuberous lining in plan with nests for laying eggs and having a perimeter horizontally arranged flange, as well as a lid in the form of an inverted tray with lateral and horizontally located upper, flat walls while the lid is mounted on the tuberous gasket with the support of its side walls on the flanging of the tuberous gasket. The cover is made with a central hole in the upper wall (for ventilation), with holes in the inclined side walls, which include hooks on the substrate, and protrusions on the inner surface of the upper wall for supporting the protrusions of the substrate located between the sockets. (RU 110073, B65D 85/32, published on November 10, 2011). This decision was made as a prototype for the lid and for packaging.

The packaging may be made of molded paper pulp, or plastic, or foam polystyrene. The surface of the upper wall of the tray is used to apply information about the product, manufacturer, etc. There is no information on the use of shrink film in the patent. Thus, we can assume that the lid is held on to the tuberous gasket due to the fact that protrusions of the type of hooks specially made on this gasket are passed into the holes on the side walls of the lid and fix it (by the type of latch).

Naturally, the bearing capacity of such a package is significantly higher than in the previously considered packaging according to RU 71640. This is due to the fact that the lid relies on the flanging of the tuberous strip around its perimeter, and the lid itself is made like an inverted tray with inclined side walls. It turns out assembled and fixed packaging, which can be used in a stack, pre-packed in boxes. In fact, the design of the known packaging repeats the design of the standard packaging for 10 eggs, in which the lid is not removable, but removable. When such a package is made of boommass, the load-bearing capacity of the package on a tuberous gasket is quite high, but it is necessary to take into account the conditions of its operation, in particular, the fact that the boommass refers to materials with high hygroscopicity.

If we consider such an opportunity as compiling a stack of well-known packages according to the prototype and without the use of boxes, or simply laying these packages on the trading floor in a one-on-one position, we can see that the abutment surface, which is the flat top wall of the lid, is significantly smaller tuberous laying. That is, if one package is placed on the lid of another package, the edges of the tuberous gasket of the upper package will hang. That is, the gasket is not fully supported. This leads to the fact that under its own weight the edge sections of the gasket can move down, which can lead to the separation of the hooks. The likelihood of this is quite high, since both the boommass lid and the tuberous lining of boommass have large tolerances when dried after casting or molding and a high degree of deviation from shape and flatness. If we take into account that, in fact, the lid and tuberous gasket are disposable products, then you can understand that improving the accuracy of casting and preserving shapes and planes (at least along the flange perimeter) is inappropriate.

In addition, in the known packaging, the side walls are made inclined. When loading the upper wall of the lid on the side walls, the forces decompose into vertical and horizontal components, one part of which is directed downward, and part acquires a horizontal vector. The forces acting in the horizontal direction burst the side walls, which leads to deformation of the upper wall and, accordingly, to the loss of the bearing capacity of the cover. In the known package, the through opening is made in the lid offset to one edge. As a result, part of the lid and the side wall adjacent to this opening become weakened in strength.

Given these circumstances, the task is to create such a package based on a tuberous mass-production gasket and a lid for it, which would have such spatial strength that would not only allow the stack to be formed without the use of boxes, but would also ensure guaranteed product storage during transportation and storage .

This utility model is aimed at achieving a technical result consisting in increasing the load capacity of the package by increasing the strength and stiffness of the lid, eliminating its deformation and transferring the load on the eggs.

The indicated technical result is achieved in that in an egg package containing a rectangular tuberous gasket made of paper pulp in plan with nests for laying eggs and having a perimeter horizontally arranged flange, as well as a lid in the form of a tray turned upside down with side flat walls and the upper horizontally located flat wall with a through opening, the lid mounted on the tuberous gasket with the support of its side walls on the flanging of the tuberous gasket, the cover it is a tray made of corrugated cardboard made of a sheet blank by bending its parts and the side flat walls of which are perpendicular to the bottom of this tray, which is the upper horizontally located flat wall, while the lid is fastened with a tuberous gasket due to heat shrink film, and the through opening is rectangular in shape in plan in the upper wall of the cover is made with the arrangement of the long side parallel to the long side of the upper wall and is located in the Central part of this wall.

The cover can be made of a corrugated cardboard sheet with a rectangular bottom with which side walls are connected along the inflection lines, each pair of adjacent adjacent ones is connected to each other in the corner zone by brackets or by inserting the tab of the folding valve of one side wall into the slot on another side wall.

The cover can be made of a sheet of corrugated cardboard with a rectangular bottom with which side walls are connected along the inflection lines, while two opposite side walls are made of two parts, the first of which, connected with the bottom, is bent from the bottom, and the second, connected with the first part, is bent through the first towards the bottom to form a double wall and is inserted with reeds into the slots at the inflection line of this side wall from the bottom, and I will bend the two other oppositely located side walls You are from the bottom and flaps inserted between the parts of the double walls.

The lid can be made of corrugated cardboard blanks having a rectangular bottom with which side walls are connected along the inflection lines, and each two opposite side walls are made of two parts, the first in each of which, connected with the bottom, is bent from bottom, and the second, connected with the first part, is bent through the first towards the bottom to form a double wall and is inserted into the slots by the reeds at the inflection line of this side wall from the bottom, while all double walls are made with bend E valves that are placed between the parts located adjacent double walls.

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

This useful model 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.

In FIG. 1 shows a general view of an unpacked package for eggs;

FIG. 2 is a first example of a sheet blank preform;

FIG. 3 is a second example of the execution of a sheet blank of a cover;

FIG. 4 - the third example of the execution of the sheet blanks of the lid;

FIG. 5 - a general view of the packaging for eggs in assembled form, the first example of execution.

According to this utility model, an egg packaging design is considered, consisting of a removable lid 1 covering the base, using a standard tuberous pad 2 (backing) of paper pulp (waste paper, pulper cardboard) for thirty (maybe twenty) eggs ( Fig. 1). As the base, a standard tuberous egg lining made according to TU 5481-001-29004177-2004 “Packaging eggs from 30 molded paper fiber” can be used (or models of tuberous laying on pages 21-31 according to the Hartmann catalog, 2009). The tuberous laying is made in the form of a monolithically molded tray of a cellular structure with dividing stops in the form of protrusions between rows of nests (cells) arranged for laying eggs. Two opposite sides of such a laying along the flanging line are made straight and limit the number of cells for eggs, and two other opposite sides along the flanging line are made straight at the end sections. Along each edge of these sides (for the sides on which a flat tongue is formed), a series of small and shallow cells are formed along the row of egg cells that are not used for egg placement and have a technological purpose. For such a tuberous strip around its perimeter, flanging 3 for technological purposes is organized. In general, this flanging is a flat area around the perimeter of the nests, continuous on some sides and interrupted by recesses on the other sides. In fact, flanging refers to the technological edge used to separate, pull out the gaskets from the packs in the drive on automatic equipment in egg production.

In the General case, the package for eggs contains a tubercle pad and closing on top of the tubercle pad removable cover made of a sheet of corrugated cardboard (Fig. 1).

The lid is a tray made of corrugated cardboard made from a sheet blank by bending its parts and the side flat walls of which are perpendicular to the bottom of this tray, which is the upper horizontally located flat wall with a through opening 4. At that, the through opening 4 is rectangular in plan in the upper wall the cover is made with the long side parallel to the long side of the upper wall and located in the central part of this wall. The location in the center of the upper wall of the opening allows for equal strength fragments of the upper wall adjacent to the side walls.

The implementation of the cover in the form of a tray of corrugated cardboard is essential to achieve a technical result. Firstly, corrugated board itself refers to a material that is durable and well-retained in the product. As a rule, corrugated cardboard of grades E (micro) and B (small) with a step of corrugation of 4.5-6.4 mm and a height of corrugation of 1.1-1.6 mm and 2.2-3.3 mm, respectively, is used for non-responsible packaging . In principle, other corrugated board profiles can be used, but this leads to an excessive increase in the strength of the lid and its cost increase with an unjustified increase in weight. In such a tray made of a bendable blank, the side flat walls are perpendicular to the bottom of this tray, which is the upper horizontally located flat wall with a through opening. Thus, the lid is a tray, in which the walls are located at right angles in the corner zones. It is known that the load-bearing capacity of boxes is affected by the preservation of right angles at the points of convergence of the walls and the preservation of the flatness of the walls. In the manufacture of trays from sheet blanks, the valves of one wall are connected to another wall, increasing the wall thickness in the corner zone. This strengthening allows you to increase the rigidity and strength of the corner zone and maintain the flatness of the walls. Therefore, the manufacture of a cover from a blank of corrugated cardboard is essential for the claimed object. Since the lid rests around the perimeter of the tuberous lining for flanging and the lid has contacts with the external (external) sections of the extreme protrusions, it turns out that the lid is tightly seated on the tuberous lining and does not have the ability to shift towards damage to the eggs.

At the same time, the surfaces of the side walls and the upper wall, where a through display window can be made, can be used to design and display special information about the product and the manufacturer. When the lid is seated on the flange, the lid and gaskets are fastened, for example, by using shrink film or tape dressing. This fastening is necessary only in order to prevent spontaneous opening of the lid when the stack is tilted at the time of transportation by the stacker or for the convenience of customers.

The flanging of the tuberous gasket itself, as a flat section, is made of small width. Therefore, when installing the cover on it, the latter occupies almost the entire width of the flanging. This allows the packaging to be formed without strongly protruding parts. This advantage is especially pronounced when such packing briquettes are stacked or stacked on a shelf of the sales area. It is this form that makes it possible to use stacking of such packages in close contact with each other. The execution of the cover with flat walls at right angles allows us to provide high load-bearing capacity of each individual package due to the fact that when stacking, the vector of the weight load is distributed only downward and closes on the corner zones of the covers that fit tightly on the flanges of the gaskets. In each subsequent row, the tuberous gaskets completely lie on the lids 1 of the previous row: complete preservation of the supporting ability of each package.

Corrugated trays with single walls or with two double walls and two single or with all double walls can be used as covers. The choice of cover design is determined by the bearing capacity parameters and the type of corrugated cardboard used. For example, with a thick corrugated cardboard (grade B), you can use a corrugated tray with single walls, and when using a thin corrugated cardboard (grade E), you can use a tray with double walls.

The following are examples of caps.

The cover with single walls (Fig. 3) is made of a sheet of corrugated cardboard with a rectangular bottom 5 (there is a through hole 4 in it), with side walls 6 connected along the bend lines, each pair of adjacent adjacent to each other in the corner zone with brackets or by inserting the tongue 7 of the flap valve 8 of one side wall into the slot 9 on the other side wall. It turns out the tray, in which all the side walls are made single.

The cover with single and double walls (Fig. 4) is made of a sheet of corrugated cardboard with a rectangular bottom 5, with which the side walls are connected along the bend lines. In this case, two opposite side walls are made of two parts, the first 10 of which, connected with the bottom, is bent from the bottom, and the second 11, connected with the first part, is bent through the first towards the bottom to form a double wall and the tongues 12 are inserted into the slots 13 at the inflection line of this side wall from the bottom. Two other oppositely located single side walls 6 are bent from the bottom and flaps 14 are inserted between the parts of the double walls. It turns out the tray, in which two opposite side walls are made double in thickness, and the other two are single.

The cover with all double walls (Fig. 5) is made of a sheet of corrugated cardboard with a rectangular bottom 5, to which the side walls are connected along the inflection lines, and each two opposite side walls are made of two parts 10 and 11, the first 10 in each of which, connected with the bottom, is bent from the bottom, and the second 11, connected with the first part 10, is bent through the first towards the bottom to form a double wall and the tongues 12 are inserted into the slots 13 at the inflection line of this side wall from the bottom. All double walls are made with bendable valves 15 placed between parts of adjacent double walls. It turns out the tray, in which all the side walls are made double in thickness.

This utility model is industrially applicable, can be made of known materials and using well-established technologies adopted in the cardboard industry and in the field of plastic packaging. The novelty of the claimed utility model consists in the implementation of the cover is completely rectangular in the form of a parallelepiped, which allows you to translate weight loads in the area of support of the tuberous gaskets on the cover of the previous row.
