Description

The invention 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.

In the framework of the present invention, such packages are considered that contain a lower part — a tubercle gasket or a substrate with appropriately formed cells intended for placement of eggs in them (as a rule, 2 or 3 dozen eggs), and the upper part — a cover intended for placement in her upper parts of the goods laid in the package, and to close the package.

Thus, an egg package is known that contains a tuberous pad of a cellular construction with dividing stops in the form of protrusions between the cells and a removable lid covering the tuberous pad from the top, made of a sheet of cardboard blank containing a central part, from which the side parts are bent for two opposite sides along fold lines the formation of two opposite side walls supported by a tuberous gasket, as well as a stiffener in the central part to support the latter on the tuberous gasket, The stiffness ebro in the middle zone of the central part is made in the form of a fold dividing the central part into left and right fields and formed by folding part of the surface of the central part between three weakened section lines made at a distance from each other parallel to the fold line, while on one of the central fields of the part, a tongue is made for inserting it into a slot made on another field of the central part, for adjoining the left and right fields of the central part to each other with the formation of a flat outer surface st with the location of the stiffener perpendicular to this surface in the direction of the tuberous gasket (RU 2507144, B65D 85/32, publ. 02/20/2014).

            The disadvantage of this package is that when external force is applied to the lid, it may lose its engagement with the tuberous gasket. This is due to the fact that the lid is held by the gasket by small valves that are worn through the slot on the technological protrusions of the gasket. The protrusions are not wide enough to guarantee that the valve is engaged.

The problem of guaranteed lid retention on a tuberous pad is solved by using shells that pack the pad with eggs inside the shell.

Thus, a shell for packing eggs in a tuberous laying is known, made of a rectangular sheet of cardboard blank containing a central part, from which four side parts are bent to form four opposite side walls, two of which, oppositely located, have flaps towards each other with the total length equal to the length of the Central part, while on the edge of one valve a tongue is made, and on the other valve a slot is made to enter this tongue when the valves are located end-to-end relative to each other over the central part (KR 20100008267, B65D 5/462, B65D 5/50, B65D 85/32, published 19.08.2010).

From the same source, an egg package is known that contains a tuberous gasket of a honeycomb structure with dividing stops in the form of protrusions between cells and a shell that covers it from below, on the sides and from above, while the shell is made of a rectangular cardboard sheet and contains a central part on which a tuberous gasket is placed and from which four side parts are bent to form four walls covering the gasket on all sides and two of which are oppositely located from They are bent towards each other and have bendable towards each other valves located above the tuberous gasket and having a total length equal to the length of the central part, while on the edge of one valve a tongue is made, and on the other valve a slot is made to enter this tongue to form a lock connection of the valves between themselves.

            This decision was made as a prototype for the declared objects.

A disadvantage of the known solution is that, in fact, the shell is made like a packing box with a lid, inside of which there is a tuberous laying with eggs. With this design, the consumption of cardboard is seriously overestimated for the cut of a complex and developed in all directions sheet blanks and the process of its assembly is complicated due to the need to fasten adjacent adjacent walls to each other in an adhesive manner. Naturally, such a shell cannot be used on the lines of industrial production of eggs and their packaging, as it requires manual intervention and time-consuming.

The present invention is aimed at achieving a technical result, which consists in improving performance by simplifying the design of the shell for tuberous laying.

The specified technical result is achieved by the fact that in the shell for packing eggs in a tuberous lining made of a rectangular sheet of cardboard, containing a central part, from which the side parts are bent to form two opposite side walls having valves bending towards each other with a total length of equal to the length of the central part, while on the edge of one valve a tongue is made, and on the other valve a slot is made to enter this tongue when the valves are located end-to-end to the friend above the central part, the valve with the tongue is made with additional valves bent away from it towards the central part and located on the sides of the tongue, the edges of which are made in the form of serrated protrusions designed for their location on the separation stops of the tuberous gasket, and the valve with a slot made with an additional valve bent away from it towards the central part, the edge of which is made in the form of gear protrusions designed for their location on the separation stops of the tuberous when it rests on the bent additional valves and the formation of a transverse stiffener on the dividing stops of the tuberous gasket, and the slot on the valve is located on the bend line from it of the additional valve.

            The specified technical result is also achieved by the fact that in an egg package containing a tuberous pad of a cellular structure with dividing stops in the form of protrusions between the cells and a shell that covers it from below, on the sides and above, the shell is made of a rectangular rectangular sheet metal blank and contains a central part on which a tuberous gasket is placed and from which the side parts are bent to form two opposite side walls, covering the gasket from two sides and having jumps Valves facing each other located above the tuberous gasket and having a total length equal to the length of the central part, a tongue is made on the edge of one valve, and a slot is made on the edge of one valve to enter this tongue to form a lock connection between the valves, the valve with the tongue made with additional valves bent away from it towards the central part and located on the sides of the tongue, the edges of which are made in the form of gear protrusions intended for their location on the separator lugs of the tuberous strip, and the valve with a slot is made with one additional valve bent away from it towards the central part, the edge of which is made in the form of gear protrusions designed for their location on the separation stops of the tuberous strip to form a transverse stiffener on the separation stops of the tuberous strip made of adjoining additional valves of both valves.

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 specific examples of execution, which, however, are not the only possible, but clearly demonstrate the ability to achieve the desired technical result.

In FIG. 1 - sheet blank shell;

FIG. 2 - general view of the packaging with a shell;

FIG. 3 - shows the process of connecting the valves to each other.

            According to the present invention, there is considered the design of an egg package consisting of a removable shell 1 covering the base, for which it is preferable to use a standard tuberous lining (backing) of pressed cardboard for twenty to thirty eggs.

In the general case, the egg package contains a tuberous gasket of a cellular structure with dividing stops in the form of protrusions between the cells and a shell covering it from below, on the sides and from above. For such packaging, the shell shown in FIG. one.

The shell is made of a rectangular rectangular sheet metal blank (Fig. 1) and contains a central part on which a tuberous gasket is placed and from which the side parts are bent to form two opposite side walls, covering the gasket from two sides and having valves bent towards each other, located above the tuberous gasket and having a total long equal to the length of the Central part.

A tongue is made on the edge of one valve, and a slot is made on the other valve for introducing this tongue to form a locking connection of the valves to each other.

The valve with the tongue is made with additional valves bent away from it towards the central part and located on the sides of the tongue, the edges of which are made in the form of gear protrusions designed for their location on the separation stops of the tuberous gasket, and the valve with a slot is made with the bend away from it to the side the central part with one additional valve, the edge of which is made in the form of gear protrusions designed for their location on the dividing stops of the tuberous strip for the formation of chno located stiffener abutments for separating lumpy gasket made of juxtaposed additional valve both valves.

A specific embodiment of the invention is described below.

As the base, a standard tuberous egg lining is used, made according to TU 5481-001-29004177-2004 "Packaging eggs from molded paper fiber for 30 pieces." The tuberous gasket is made in the form of a monolithically molded tray with a cellular structure with dividing stops in the form of protrusions between in-line cells intended for laying eggs. The shape of the cells is semi-elliptic volumetric (hemispherical), close to the shape of the lower or upper half of the egg. Along each edge of these sides (for the sides on which a flat tongue is formed), a number 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.

The shell 1, covering the bottom, on the sides of two oppositely located sides and on top (from the side of placement in the egg cells) of the tuberous gasket, is made of sheet cardboard blanks from corrugated cardboard (Fig. 1). The sheet blank is made of a sheet close to a rectangular shape, and contains a central part 2, rectangular in shape in plan (length A and width B), from which side parts 4 are bent along two opposite sides along fold lines 3 to form two opposite side walls 5 (Fig. 2). These walls 5 have bendable towards each other valves 6 and 7 (with a length of B each), with a total length equal to the length of the central part 2 (A = 2B), while on the edge of one valve 6 a tongue 8 is made, and on the other valve 7 is made a slot 9 for introducing this tongue when the valves are located end to end with respect to each other above the central part.

Thus, the final position of all parts of the shell is a flattened box without top and bottom, the cavity of which is designed to accommodate the tuberous gasket.

In the upper part of the shell, the valves 6 and 7 are interconnected by a locking connection due to the insertion of the tongue 8 of one valve 6 into the slot 9 on the other valve 7. But such a connection is unreliable, since the valves bend and fail towards the gasket and, as such, can damage the eggs. To exclude the disclosure of the lock connection, one valve 6 (having a tongue) is made with additional valves 10 bent away from it towards the central part and located on the sides of the tongue 8, the edges of which are made in the form of gear protrusions intended for their location on the dividing stops of the tuberous gasket. And the valve 7 (with a slot) is made with an additional valve 11 bent away from it towards the central part or consisting of several parts, the edge of which is also made in the form of gear protrusions intended for their location on the separation stops of the tuberous gasket.

When connecting valves 6 and 7, additional valves 10 and 11 are bent towards the central part of the shell, located transversely to valves 6 and 7 and adjacent to each other over the entire surface. Thus, when the bent additional valves are supported against each other, a transverse stiffener is formed, resting on the dividing stops of the tuberous gasket. In this case, the slot 9 on the valve 7 is located on the inflection line 12 from it of the additional valve 11.

Since the shape of the protrusions is serrated and the shape of the cells has depth and walls, the lid cannot be displaced in the transverse direction. While the Central part of the shell is loaded with a gasket, the side walls 5 are supported by the technological edges of the gasket. And the valves 6 and 7 are interconnected and at the same time have support through the stiffener to the gasket. Thus, the shell is reliably positioned on the tuberous gasket without displacements in the transverse directions. To exclude the exit of the tongue from the slot, this tongue can be performed with extensions 13 on the sides that pass through the end sections 14 at the slot, breaking the edges of these sections (Fig. 3). After penetrating inward, the extensions restore their shape, but cannot go outside, since they abut against the inner surface of the wall formed by an additional valve 10 in the stiffener.

The packaging is easy to manufacture and does not require special equipment, because it uses standard tuberous egg pads and a cardboard shell obtained by die cutting. The packaging has high operational properties and attractiveness for the buyer, since it provides guaranteed preservation of the integrity of the eggs even when loaded on the shell. The packaging has a stiffening rib and is strong enough to be stored in a stacked form. The shell is highly manufacturable while minimizing waste, and the upper flat surface of the shell and its flat side walls allow printing information directly on the shell in the form of its blank and on the packaging.

The presence of a transverse stiffener allows you to clearly maintain the position of the surface of the shell relative to the tuberous gasket and, thereby, to form an air cavity between the shell and the base, which is very important for the organization of air exchange and ventilation of eggs in the conditions of their storage. The upper surfaces of the shell may have additional elements of grooves, such as a window 15 (window) for visual assessment of eggs inside the package from above, perforation, printing, lamination, etc.
