Description

Technical field

The utility model relates to packaging containers made of molded paper pulp and can be used for storing and transporting eggs.

State of the art

Known packaging for eggs, made by molding of expanded polystyrene or pressed paper pulp, containing a base connected to the lid along the inflection line in the form of a rectangular tray in plan, in which two rows of semi-ellipsoidal cells separated by walls with a cylindrical base for placing eggs are made, in In the tray between the cells there are dividing stops made in the form of at least two protrusions with a height higher than the flanging of the tray, and the locking mechanism is a valve connected to the tray along the inflection line, on which the protrusions are formed, and the slots for these protrusions are made in the side wall of the cover for placement valve inside the lid along this side wall and inserting the protrusions into the slots while resting the lid flange on the tray flange and valve thickening (see RU 2 500 596 C1).

The use of a folding valve in the locking mechanism is not able to ensure a reliable connection of the lid to the base, since there is a risk of spontaneous folding of the valve within the limits of the elasticity of the material, even with a slight mechanical effect on the package, for example, in the process of carrying or otherwise moving the package. Spontaneous bending of the valve may lead to the opening of the package with the loss of the contents.

A molded egg package is known, comprising a base formed with cells having non-planar side surfaces corresponding to parts of the external configuration of the packaged product, placed in at least two rows with separating ledges and a structure of retaining ribs between the cells, and a lid formed with flat surfaces on the top and sides and convex areas reflecting the shape of the packaged goods, connected by a hinge on the back side and equipped with at least two locking devices, each of the opening on the front side of the cover and the latch on the front side of the base, made with the possibility of interaction between for releasable fixation of the base and cover, the opening of the locking device is located under at least two niches, and as a latch of the locking device, a protrusion of the beak type is made, which is located between the outer side surfaces of the corresponding adjacent cells protruding upwards (see Fig. RU 148 047 U1).

The execution of the lid with flat surfaces on the top and sides limits the possibility of stabilizing the relative position of the lid and the base only by a hinged connection along the inflection line. The resulting displacement of the lid and base in a closed package or when it is closed leads to deformation and crumpling of the protrusions of the locks, which worsens the hook and reduces the reliability of fixing the closed state of the known package.

The beak-shaped protrusions are characterized by a low force to break the connection due to the low rigidity of the structure, which leads to low reliability of fixing the closed state of the container during operation.

The closest in technical essence - the prototype is a molded container for eggs, including a base and a lid, made from a single tuberculate blank by bending along the grooves located along the inflection line, containing cells for placing eggs, surrounded by protrusions that are in contact with each other by means of stiffeners, protrusions , located on the base, have through holes at the tops, and the protrusions made on the cover have at the tops protruding elements of a cone-shaped stepped shape, located symmetrically to the holes, relative to the inflection axis, with the possibility of the cone-shaped protruding elements entering the holes to form a locking connection (See Fig. RU 2634236 C1).

The presence of cone-shaped protrusions and corresponding holes allows you to fix the relative position of the base and cover, helping to reduce their mutual radial displacement relative to the axis of the protrusion. However, the known solution does not provide any significant fixation of the connection in the longitudinal direction along the axis of the connection, allowing the protrusion under the action of elastic forces, bent at the inflection point of the container material, to leave the hole.

The presence of frictional forces between the protrusion and the edge of the hole allows to some extent to keep the connection, however, the location of the protrusions and holes near the inflection line, in this case between rows of cells, limits the lever arm, not providing reliable fastening of the two parts of the container.

Unintentional opening of the container, in turn, may result in loss or damage to the fragile contents of the container.

This disadvantage limits the scope of the known solution to cases where users take additional measures to securely fix the closed state of a known container.

Essence disclosure

The technical result is to expand the scope by providing reliable fixation of the closed state of the container.

This result is achieved by the fact that in the container for eggs, made of molded paper mass as a single part, containing cells for placing eggs, stiffeners formed by connecting the walls of these cells, a line of inflection dividing the container into two parts, one of which is provided with protrusions, and the other - with holes corresponding to them, so that in the closed state the protrusions of one part are in the corresponding holes of the other part, both parts of the container are made cellular, the protrusions and holes are located at the container parts opposite from the inflection line, the protrusions are made hollow, having side walls with openings , and the holes are equipped with consoles, made with the possibility of engaging with their edge over the edge of the opening of the corresponding protrusion.

In addition, the console is made protruding into the opening of the form.

- the width of the opening corresponds to the width of the console.

- the edges of the opening and the console are made so that the points of their interaction form a plane.

Implementation of the utility model

The egg container is illustrated with the help of the drawings, where in FIG. 1 shows a general view of the container, Fig. 2 - fragment A of the container in the area of the lock connection, in Fig. 3 - front view of the lock connection, in Fig. 4 - lock connection in section, in Fig. 5 - lock connection of an open container, in Fig. 6 - lock connection of a closed container.

The following designations are made in the drawing:

1, 2 - one (upper) and other (lower) parts of the container, respectively, 3 - cells for eggs, 4 - stiffeners formed by connecting the walls of the cells, 5 - axis of the inflection line, 6 - ledge, 7 - hole, 8 - opening in the side wall of the ledge, 9 - console, 10 - upper edge of the console, 11 - upper edge of the opening, 12 - front sides of the container parts, 13 - edge along the perimeter of the container, 14 - rear sides of the container parts adjacent to the inflection line.

The container for eggs is structurally made of a molded paper pulp with a certain degree of elasticity, and consists of two parts connected to each other along the inflection line. Each part contains cells arranged in two rows along the inflection line for placing eggs, stiffening ribs formed by the walls of these cells and their connection. In this case, the outer walls of the container are formed by the walls of the corresponding cells for eggs, and the semi-ellipsoidal shape of the cells corresponds to the outer shape of the eggs to be packed.

Both parts of the container have rear walls adjacent to the inflection line and front walls opposite to them with elements of a lock connection containing protrusions and holes corresponding to them.

Hollow protrusions are located on one of the parts of the container - the bottom, and the holes corresponding to them along the profile on the other part of the container - the top.

The protrusions and their corresponding holes are located on opposite parts of the container symmetrically with respect to the inflection line, so that in the closed state of the container the protrusions of one part are located in the corresponding holes of the other part. The protrusions and the holes corresponding to them are made on the stiffening ribs of the container.

In a particular case of execution, the protrusions have lateral and flat upper walls. In other cases, the protrusions are formed only by the side walls. The side walls of the protrusions are made with openings that form a kind of hollow, and the openings corresponding to them on the other part of the container are provided on the same front side with consoles, which, among other things, play the role of the front wall of the openings. The location of the consoles of the holes corresponds to the location of the openings of the corresponding protrusions.

In a particular case, the execution of the console is made protruding into the hole, in this case - towards the inflection line. In another particular case of execution, the console is made flat. The hook of the upper edge of the console with the upper edge of the opening form a locking connection, fixing the closed state of the container.

In a particular case of execution, the width of the opening corresponds to the width of the console, so that in the closed state of the container, the consoles are placed in the openings of the corresponding ledges. In other special cases of execution, the width of the opening corresponds only to the part of the console protruding into the opening.

The edges of the console and the opening interacting with each other form a flat surface, so that the points of their interaction lie in the plane. In another particular case, the edges of the console and the opening are made in an arcuate shape, so that the points of interaction form, for example, a parabola.

The protrusions and holes are made on the transverse stiffening ribs of the container at the opposite sides of the container relative to the inflection line.

The shape of the holes corresponds to the shape of the section of the protrusions, with the exception of the part of the console protruding inwards, which interacts with the upper outer edge of the protrusion when closing.

The fold line is made by creasing or perforation along the fold axis and serves as a hinged connection of two parts of the container.

In the preferred embodiment, the number of interlocks corresponds to the number of ribs formed by the connection of cells in a row. So if a row consists of five cells, then the number of locks is four.

In other special cases of execution, the number of locks may be less, for example, there may be only two locks located along the edges of the container.

In the preferred case of private execution, the protrusions are made cone-shaped, which facilitates their entry into the holes. In other special cases of execution, the protrusions can be made cylindrical or otherwise.

The edge along the perimeter of the container is made with flanging outward, forming the area of the surface of mutual contact and stop of the walls of the two parts of the container, so that its closure is limited by the stop of the outer walls of the two parts of the container. Thus, the closed state of the container is limited: in the direction of approach of the parts by the mutual abutment of its outer walls, and in the opposite direction by the abutment of the edges of the consoles into the edges of the openings of the corresponding protrusions.

The egg container is used as follows.

The inflection line is made with a line of reduced strength, whereby the closing or opening of the container is carried out by mechanical action simultaneously on both parts of the container, which is bent directly along the inflection line.

Storage and transportation of empty containers is carried out in their open state, which saves space by collecting containers in stacks of several dozen.

In the process of closing the container, the protrusions of one part go into the holes of the other part corresponding to them in shape, providing the direction of movement of the container parts.

The direction of movement of the two parts of the container when it is closed is also facilitated by the presence of cells for eggs on both parts. So, in a filled container, eggs placed in the cells of one part of the container contribute to the direction of movement of the walls of the cells of its other part, eliminating the possibility of distortions, which facilitates the entry of the protrusions into the corresponding holes, eliminating jamming of the protrusions, which, in turn, contributes to the reliability of fixing the closed container states

The shape of the openings correspond to the dimensions and section of the protrusions, which facilitates the process of closing the container and contributes to the correct orientation of the protrusion opening relative to the opening console.

The hook occurs at the moment when the top edge of the console falls below the top edge of the ledge opening. The original shape of the walls of the protrusion and the console, elastically deformed in the process of advancing the protrusion inside the hole, is restored due to the elasticity of the material, fixing the interlock.

The shape of the console with a deflection inside the hole improves the elastic interaction of the console with the walls of the protrusion.

In order to open the container, press on the upper parts of the walls of the protrusions, removing obstacles to remove the protrusions from the holes.

The lock connection is provided by the interaction of the end parts of the walls of the console and the protrusion, which are oriented in parallel and may have a height sufficient to ensure the strength of these deformable elements. At the same time, the opening of the lock does not require actions aimed at tearing off the elements of the lock, or bending them to a critically large angle, which contributes to the reliability of fixation for a long time of operation.

The location of the protrusions and holes at the opposite sides of the container relative to the inflection line, i.e. as far as possible from the inflection line allows you to extend the lever arm to the maximum length, reducing the load on the elements of the lock and increasing the reliability of the lock connection.

Execution of cells for placing eggs on both parts of the container, the presence of hollow ledges and holes corresponding to them, located at the parts of the container opposite from the line of inflection, making the side walls of the ledges with openings, making holes provided with consoles, made with the possibility of hooking their edge to the edge of the opening corresponding protrusion, provides the possibility of reliable fixation of the closed state of the container.

The egg container can be made from molded paper pulp using standard equipment.

Thus, the egg container provides a wide range of applications by providing a secure locking of the closed state of the container.
