Description

The invention relates to containers, in particular to packaging such as a tray, container, egg box for eggs, and is intended for storage and transportation of eggs.

Known packaging for storing and transporting eggs, including a base with cells for eggs, stiffeners located between the cells, the lateral and central stops and the outer protrusions in the corners and the lid-liner with nested parts, characterized in that the cells are made with inner and outer ribs stiffnesses located on their lateral surface, with lodges located at the base of the cells, dampers located on the bottom of the cells, and internal protrusions located at least between one pair of cells on the side the surface of the base, and the side surface of the base is made with internal protrusions located at least between one pair of cells, while the lid of the liner is made with cutouts arranged to interact with the internal protrusions of the base (RU 46477, B65D 85/32, publ. . 07/10/2005).

The disadvantage of this package is its lack of rigidity due to the design features of the cells that do not provide the proper integrity of the eggs during storage and transportation, and the possibility of tipping along the long side, which also leads to damage to the package and eggs.

The present invention aims to achieve a technical result, which consists in increasing operational reliability by increasing the bending stiffness of the tray to increase the reliability of egg storage.

The specified technical result is achieved in that in an egg package containing a base in the form of a tray, in which two or more rows of egg cells are made, as well as separation stops located in the tray between the cells, ring-shaped dampers at the bottom of the cells in the form of ring-shaped recesses directed inside the cells, while along the perimeter of the tray a stiffening rib is made in the form of a flange, each cell is made in the form of smoothly mating spherical surfaces close to the shape of eggs, the bottom of each cell is made of lindroobraznogo form, in the bottom of which there is an annular recess, which is an annular damper, and the bottom parts of all cells are connected by jumpers to form an annular stiffener in this part of the tray, the separation stops between the cells are made in the form of protrusions, distantly located on the flange of the tray around the perimeter protrusions oriented in the direction from the flanging to form channels for air exchange, while the tops of the separation stops and at least part of the protrusions on the flanging are located in a common horizontal plane.

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

The essence of the invention lies in the application of a new scheme for the formation of stiffeners, which ensures an increase in the bending stiffness of a package like a tray, which eliminates the deformation of cells for eggs and, accordingly, ensures the safety of eggs.

The packaging is molded from pressed paper pulp, but can be made of expanded polystyrene, PET, etc.

The following is an example of a package designed for storing one dozen eggs.

Packaging for eggs is a base in the form of a rectangular-shaped tray in the plan (figure 1), in which two rows of cells 1 for eggs are made. Each cell is made in the form of smoothly mating spherical surfaces close to the shape of eggs, and practically repeats the shape of an egg, which creates certain conveniences for laying and storing eggs, since the latter in a cell of this shape do not change their position and are not able to move or swing. The depth of the cells is selected based on the excess of egg height. Due to the fact that the cells are open, the implementation of cells with a depth greater than the height of the egg does not prevent the quick and easy delivery of eggs with your fingers. The cells in the tray are formed adjacent to each other in two rows and thus form the side and end walls of the tray in the form of hemispherical protrusions 2. Traditionally, such a shape of the tray does not have sufficient rigidity in the manufacture of sheet polymer materials.

To give the tray a sufficiently high spatial cruelty and to maintain the shape in the tray, a new scheme of stiffening ribs, which are simultaneously components of the tray itself, is used. In the tray between the cells there are separation stops 3. The shape of the walls of these protrusions is spherical in height, since these protrusions are also part of the walls of the cells. These protrusions perform the function of damping egg vibrations in the transverse direction.

A stiffener is made along the perimeter of the tray in the form of a flange 4, which forms a rigid belt along the upper contour of the tray. On the flanging of the tray around the perimeter there are distantly located protrusions 5, oriented in the direction from the flanging, which form openings between themselves, which are channels for air exchange, and these protrusions can be supports for the lid, which the tray can be covered with.

The bottom part 6 of each cell is made not of a spherical shape, but of a cylindrical shape, in the bottom of which there is an annular recess 7, which is an annular damper, and the bottom parts of all cells are connected by jumpers 8 to form an annular stiffener in this part of the tray. The ring-shaped dampers at the bottom of the cells in the form of ring-shaped recesses directed inside the cells are a compensator for the impact on the walls of the weight of the egg when it falls into the cell.

Thus, two stiffening belts are formed in the tray: the upper in the form of a flanging with protrusions and the lower in the form of an annular stiffening rib covering the bottom of the cells. In the vertical direction, the cells are limited by the height of the separation stops.

A feature of the design of the tray is that the vertices of the part (two, three, or more, or all) of the separation stops and the vertices of at least part of the protrusions (for example, three protrusions) on the flange are located in a common horizontal plane, and the vertices of the protrusions located opposite each other on the flanging can be located in the transverse plane passing through the top between them located separation stop. The vertices of the protrusions located opposite each other on the flanging can be offset with respect to the vertices of the separation protrusions. This arrangement of the protrusions and stops excludes possible effects on the egg laid in the cell from the side, for example, of the lid or other packaging covering the tray, since the protrusions and stops are limiters. With this design, trays of one row can be crossed with pallets to accommodate trays of the next row.

This condition is also fulfilled for the design of the tray, designed for one and a half, or two, or three dozen eggs. With an increase in the number of rows of cells (Fig. 5), the design features of such increased in volume trays remain the same as in the considered example for a tray of one dozen eggs. Also important for such trays, in which the number of rows of cells exceeds two, is the fulfillment of the condition according to which the vertices of the part (two, three, or more, or all) of the protrusions on the peripheral part of the tray should be in the general horizontal plane of at least part of the separation stops which are located either in one row of such stops (separating two adjacent rows of cells), or in adjacent rows of stops (part of the stops in one row and part of the stops in another row, etc.). This allows for each tray, regardless of its capacity, to form a supporting structure, on which you can put a palette.

Since the trays for transportation to the consumer are stacked in packs, to prevent them from sticking in the pack due to the adhesion forces between the walls under the flanging, transverse projections 9 are made in the corner zones of the tray to support each next tray stacked in the previous tray when forming the stack of trays.

The result is an increase in durability and the provision of reusable use, an increase in the reliability of egg storage due to a decrease in the possibility of deflection of the tray, an increase in the rigidity and stability of the packaging structure during storage, and a decrease in the possibility of contact between the eggs. The packaging ensures the safety of eggs during transportation and is ventilated, i.e. "breathes", which is a prerequisite for the preservation of eggs.
