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.

Many forms of packaging are known for packaging and transporting fragile goods such as eggs. Traditionally, such packages contain a lower part - a tuberous lining or a substrate with appropriately shaped cells designed to place eggs in them (usually 2 or 3 dozen eggs), and the upper part - a cover designed to accommodate the upper parts of the goods laid in it into the package, and to close the package.

For example, the simplest egg packaging used in retail is known [egg packaging for the Seymovskaya poultry farm, Internet information at: http://www.seyma.ru/index.php?vv=news5]. The packaging does not require special molding equipment for the manufacture of the substrate and the lid, since these structural elements use standard tuberous linings for 30 eggs, used for storing the product in warehouses and transporting in outer containers - large cardboard boxes. The substrate with the eggs placed in it is covered with a lid - the same tuberous gasket and placed in a shrink film, which serves to preserve the integrity of the package. A sheet with the accompanying information is laid under the film sheath. Ease of packaging is its advantage. However, the eggs placed in it are not visible to the buyer, which may raise doubts about the quality of the goods and the integrity of the eggs. In addition, since a tuberous gasket is used as a cover, inserts are required for product information.

This disadvantage is deprived of the egg packaging, which incorporates a tuberous pad-substrate of a honeycomb design with hollow dividing stops, into the cells of which the 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 fold lines 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 top plane, the cut parts of which are bent inward with the formation of stiffening ribs having serrated protrusions, the shape of which allows their fixation in the cells of the substrate (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.

Another serious drawback of such packaging is that the lid rests on both sides of the nest walls in which the eggs lie. These walls are made with protrusions that lead into the cavity of the nests on the sides of the eggs. This allows you to hold the lid over the eggs and eliminates its displacement relative to the gasket. But, if the load on the cover exceeds the permissible, then these tabs in the form of reeds break and the cover sits on the eggs.

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.

The disadvantage of this package is that it can only be used on tuberous gaskets that have technological flanging around the perimeter. If there is no flanging in the tuberous gasket along its perimeter, then the lid cannot be held on this gasket. It should be noted that bezborodkovy tubercular gaskets are as widely used in the egg production area as tubercular gaskets with technological flanging. Both types of gaskets are almost identical in design, but have differences in the design of the edge sections. The marginal areas in the tuberous lining with flanging are limited by protrusions that coincide in shape with the protrusions that divide the nests for eggs in the central part of the strip. And in a gasket without flanging, the edge sections are limited by additional protrusions, each of which represents half the usual protrusion between the sockets. Technically, such an additional protrusion is presented in the form of a protrusion cut in the vertical direction, dividing the nests for laying eggs on the surface of the indicated strip and facing a flat wall outward from the edge of the tuberous strip. These peripheral protrusions on the outside form a certain contour that can be used as guides for putting on the cover. But, still, the problem remains in holding the cover on the gasket due to the lack of flanging.

Given these circumstances, the task is to create such a package based on a tuberous mass-produced gasket and a lid for it, which would have such spatial strength that would ensure guaranteed product storage during transportation and storage due to reliable lid retention on the gasket.

This utility model is aimed at achieving a technical result, which consists in increasing operational performance by providing increased strength and rigidity of the lid, eliminating its deformation and transferring the load on the eggs.

The specified technical result is achieved in that in an egg package containing a tuberous rectangular gasket in plan with nests for laying eggs and a lid in the form of a tray turned upside down, having side flat walls and an upper horizontally located flat wall in which a through opening is made, the lid is mounted on a tuberous gasket, the tuberous gasket is made without flanging with a location along its perimeter and in the corner zones of the edge protrusions, the cover is a corrugated tray of octagonal shaped cardboard in plan, 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 with a through opening, while the side walls of the lid in the corner zones are beveled to form additional walls located on the tuberous gasket in its corner zones from the inner side of the edge protrusions located in these zones.

For this example, the lid can be made of corrugated cardboard blanks having a rectangular shape with a bottom with beveled corners with which side walls are connected along the bend lines, while two opposite side walls are made of two parts, the first of which is connected to 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 in the slots at the inflection line of this side wall from the bottom, and the other two are opposite but the lateral walls located are bent from the bottom and each is made with two valves sequentially arranged along the length of these side walls, the first of which are laid along the bevels, and the others connected with the first are bent away from them and inserted between the parts of the 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.

The present utility model 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.

In FIG. 1 is a General view of the flangeless tubercular strip of known design;

FIG. 2 - a general view of the package for eggs in disassembled form;

FIG. 3 - an example of the execution of the sheet blanks of the cover;

FIG. 4 is a perspective view of a cover assembled from the sheet blank of FIG. 3;

FIG. 5 - a fragment of the package, the position of the beveled wall in the corner zone of the tuberous strip;

FIG. 6 is a fragment of the package in the area of the positioning protrusion.

According to this utility model, the design of an egg package (Fig. 2) is considered, consisting of a removable lid 1 that covers the base, using a standard tuberous pad 2 (substrate) made of paper pulp (waste paper, pulper cardboard) for thirty (possibly for twenty) eggs (Fig. 1). As a base, a standard tuberous egg lining made in accordance with TU 5481-001-29004177-2004 “Packing eggs from molded paper fiber for 30 pieces” (or models of tuberous laying on pages 21-31 according to the Hartmann catalog, 2009) can be used. The tuberous gasket is made in the form of a monolithically molded tray of a cellular structure with dividing stops in the form of protrusions 3 between row-wise nests 4 (cells) intended for laying eggs. Along each edge of the sides of the tuberous laying and in the corner zones, there are edge protrusions 5, each made in the form of a protruded section in the vertical direction, dividing the egg-laying nests on the surface of said laying and facing the flat wall 6 outward from the edge of the tuberous laying.

The gasket itself is made flawless, that is, it practically does not have technological tides along the outer perimeter. In principle, some technological tides are present, but they do not have a developed area sufficient to be considered as a supporting surface, for example, for a corrugated wall. In this regard, this type of tuberous gaskets is named as flawless.

In the General case, the package for eggs contains a tuberous pad and closing on top of the tuberous pad removable cover made of a sheet of corrugated cardboard (Fig. 2).

The lid is a tray made of corrugated cardboard made from a sheet blank by bending its parts and the side flat walls 7 and 8 of which are perpendicular to the bottom 9 of this tray, which is the top horizontally located flat wall with a through opening 10. The presence of a through opening 10 allows you to visually assess the quality packed eggs. The implementation of the cover in the form of a tray of corrugated cardboard is essential to achieve a technical result. 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.

Moreover, the side walls of the lid in the corner zones are beveled with the formation of additional walls 11 with a length not exceeding the distance along the line 12 passing in the corner zone of the tuberous strip (approximately at an angle of 45 °) from one of its edges to the adjacent edge of this strip past the edge of the protrusion 5 in this corner zone from its inner side.

Thus, the lid is made in the form of an octagonal tray turned upside down, the large-sized walls 7 and 8 of which are located outside the edge protrusions 5, and the additional walls 11 of small length are located on the tuberous gasket on the inside of the edge protrusions in the corner zones, as shown in FIG. 5. With this design, the lid has a support directly on the inner surface of the corner zones of the gasket, is held by resting on the surface of the gasket inside the edge protrusions, and is prevented from being displaced by the outer corner edge protrusions and the inside of the cover edge protrusions along the edges of the gasket itself. Thus, the cover is reliably positioned on the flangeless gasket. Full fixation of the packaging for transportation can be carried out through the use of shrink film or tape fastening.

Thus, the lid is a tray, in which the walls are located at right angles in the corner zones. It is known that the bearing capacity of the boxes is determined not by the wall thickness, but 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 box trays from sheet blanks, the valves of one wall are connected to another wall, increasing the thickness of the walls 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 invention. The strength and rigidity of the cover in terms of maintaining the spatial shape exceeds the mechanical properties of the tuberous gasket.

At the same time, the surfaces of the side walls and the upper wall, where the through demonstration hole is made, can be used to design and display special information about the product and the manufacturer.

When installed on a tuberous gasket cover, the latter occupies almost the entire surface of the gasket. This allows you to form a parallelepiped-shaped package without 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 load is distributed only downward and closes on the corner zones of the covers that fit tightly on the corner parts of the gaskets. In each subsequent row, the tuberous gaskets completely lie on the covers of the previous row: complete preservation of the supporting ability of each package. The bearing capacity of the tuberous gaskets is determined by the full contact of the bottom parts of the nests.

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 is an example of an octagonal cover design.

The cover with single and double walls (Fig. 3) is made from a sheet of corrugated cardboard with a rectangular bottom 9 with beveled corners, with side walls 7 and 8 connected along the bend lines. In this case, two opposite side walls 7 are made of two parts 13 and 14, the first 13 of which, connected with the bottom 9, is bent from the bottom, and the second 14, connected with the first part 13, is bent through the first towards the bottom to form a double wall and the tongues 15 are inserted into the slots 16 at the inflection line this side wall from the bottom. Two other oppositely located side walls 8 are bent from the bottom 9 and are each made with two valves 17 and 18 sequentially arranged along the length of these side walls, the first 17 of which are laid along the bevels of the bottom, and the other 18, connected with the first, are bent away and inserted between parts of double walls 7.

In addition, as a rule, tuberous gaskets without flanging are performed with punching 19 at least under two sides. Punching are small technological recesses along the edges of the sides of the gasket (Fig. 6). It is fashionable to use these recesses as additional support elements for fixing the cover. To this end, in the sheet blank (Fig. 3) along the bend line in the double walls of the wall part 14 relative to its part 13, arcuate slots 20 are made. When bending the part 14 relative to the part 13, the tongue 21 is formed from the slot 20 (Fig. 4), which when putting on the lid is recessed into the recess of the stamping 19 (Fig.), performing the function of both an emphasis and a limiter for displacement. Thus, additional positioning of the lid on the tuberous gasket is carried out. However, not all designs of bezborortovy tubercular gaskets have such punching.

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 the weight loads into the bearing area on the tuberous gaskets.
