Description

Folding tray.

A utility model relates to packaging intended for the storage and transportation of food and industrial products.

Packaging is known for food products, for example), fast food products, including burgers, pieces of fish, meatballs, as well as for cold and bakery products (see RF Patent No. 2136557, BS. B & 5D of 09/10/1999). The package includes a paper bag and a cardboard part having a base with a central fold line and walls: and, rotated to the base along additional fold lines, to enable flat folding and straightening of the bag to open the package; the side walls of the package are attached to the side walls of the cardboard part in such a way that when the cardboard box is expanded, the lower part of the package is also opened to receive objects packed into it,

The disadvantage of this design is the complexity and the inability to reuse due to the fragility of the paper bag.

Closest to the technical nature of the claimed utility model is a folding tray formed from a cardboard blank containing a rectangular bottom, stiffeners, which are a continuation of two opposite side walls, made in pairs on each side wall and rigidly attached to other side walls on the inside tray, and the side walls to which the ribs are attached have bends on both sides, directed at an angle of 45 from the corners of the bottom of the tray to its upper edge and could They are equipped with ventilation openings, and the stiffeners can be in the form of isosceles right-angled triangles, the hypotenuses of which coincide with the fold lines of the side walls (RF certificate at ПМ No. 18696 dated March 16, 2001, Yu1.V65V5OD.

The well-known technical solution is made as a prototype of this utility model.

The disadvantages of the known design of the folding tray is

low moisture resistance and lack of aesthetics of appearance.

The objective of this utility model is to create a folding

multipurpose tray

moisture resistance and high aesthetics of the external appearance.

Delivered. the problem is solved in that in a folding ijoTKe formed of a cardboard blank containing a rectangular bottom, stiffeners, which are a continuation of two opposite side walls, made in pairs on each side wall and rigidly attached to other side walls on the inside of the tray, and the side the walls to which the stiffeners are attached have bends on both sides, directed at an acute angle from the corners of the bottom of the tray to its upper edge, and can be equipped with ventilation holes, the ribs are the sharpnesses can be, for example, in the form of isosceles right-angled triangles, the hypotenuses of which coincide with the fold lines of the side walls, the folds of the side walls can be equipped with notches or holes for the drainage of moisture, and the workpiece is made of any domestic or imported cardboard, including corrugated, boxed, as well as cardboard laminated with paper or synthetic film.

The applicant has not identified technical solutions that are identical to the proposed utility model, which allows us to conclude that it meets the criterion of novelty. The inventive utility model also meets the criterion of industrial applicability, as it can be manufactured industrially from known materials. Using known technical means.

The essence of the utility model is illustrated by drawings, which depict: FIG. 1 - reamer (blank) folding tray;

FIG. 2 - folding tray in the process of bringing it into working position (or folding) in a perspective view;

FIG. 3 - a folding tray assembled in a perspective view; figure 4 - scan folding tray.

A folding tray is formed from a cardboard blank. The tray contains a bottom 1, long side walls 2, short side walls 3, ribs 4. Stiffeners 4 are a continuation of two opposite walls, in a specific example, short walls 3. On each of the walls 3 there are two stiffeners 4. Four blanks 5 are made in the blank for manufacturing a folding tray, as well as bends 6 parallel to the long side walls 2 , and bends 7 parallel to the short side walls 3. The ribs 4 are attached to the side walls 2 from their inner side, for example, with glue. Mounting with metal brackets, adhesive tape, etc. is possible. On the side walls 2, bends 8 are made, directed at an acute angle from the corners of the bottom of the tray to its upper edge, and there may be ventilation openings shown in FIG. In the examples of the specific implementation of the folding tray

the acute angle was 45 (Figs. 1,2,3,4), as well as 63 and 47. The folds 6.7 of the side walls 2,3 may have cuts or openings for the drainage of moisture (shown in FIG. 2).

To fold the dog, pressure is exerted externally on the side walls 2, while the tray comes first to the position shown in FIG. 2, and then folds and forms a flat structure. Unfolding the tray is carried out in the reverse order, the tray comes into working position, shown in Fig.Z.

As a cardboard blank in specific examples of the implementation of the utility model used a variety of cardboard produced both in Russia and abroad, for example,

corrugated boxed; laminated cardboard; cardboard laminated with synthetic film (polyethylene or polyethylene terephthalate).

The inventive folding tray has increased moisture resistance and high aesthetics of appearance, which allows to expand its functionality.
