Description

The invention relates to a carton and can be used for packaging, hand carrying and storing all kinds of consumer products, soft drinks, fruits, wine sets, etc. in various sectors of the national economy and product market.

A known cardboard box made of a sheet blank divided by kink lines into sections forming two end and two side walls, valves for forming the bottom, adjacent to the side walls valves forming the cover, each of which is provided with a handle bent upwards in the center of the cover and located along both sides of it are shaped protrusions, and adjacent to the end walls of the valves, each of which has a central slot to interact with her paired figured protrusions of the valves forming the lid .

A disadvantage of the known carton design is that the lid is not securely closed.

The purpose of the invention is to increase the reliability of closing the lid of the carton.

This goal is achieved by the fact that in the proposed carton design the central slot of each valve of the end wall is U-shaped to form a fold-out tongue, and on each figure ledge on the handle side an open horizontal groove is placed to accommodate the pull-out tongue.

New in the proposed technical solution is the introduction into each valve of the end wall of the central slot of the U-shaped form with the possibility of forming a fold-over tongue.

On each figure ledge from the side of the handle there is an open horizontal 4

nick groove for placing the fold-in tongue in it.

When the valves of the end walls are folded when the lid is closed, the central slot of each valve is passed through a paired figure ledge, while the end of the fold-down tongue is placed in an open horizontal groove on each figure ledge. Under the action of elastic deformation, the foldable tongue fits into the open horizontal groove of the figured protrusion.

These elements interact with each other, form new constructive connections, and provide increased reliability of closing the lid of the cardboard box.

1 shows a blank carton; 2 shows a cardboard box assembled, axonometric; on fig.Z - main view; figure 4 is a view of A; on fig.Z - the left end wall with the top valve to the assembly; FIG. 5, view B in FIG. 3, right end wall with upper flap before assembly; FIG. FIG. 6 is a view B of FIG. 3, the bottom of a carton.

The carton box is formed from a single flat blank, which has an inflection line of 1, parallel to its sides. In the manufacturing process, a side wall 2 is formed with the bottom flap 3 and the leaf A (Fig. 1).

In the upper part of the side wall 2 there is a horizontal valve 5 (FIG. 2) and a vertical folding valve 6 having a handle 7.

In the middle of the handle 7, an opening 8 is made for manually carrying the carton. On both sides of the vertical folding handle 7, figured projections 9 are arranged symmetrically around the edges, in which a horizontal open groove 10 is made on the inner side surface of the handle 7. A left end wall 11 with a lower flap 12 and a tab 13 is adjacent to the side wall 2. The middle part of the upper valve 14 of the left end wall 11 is made of a U-shaped slot 15, during the cutting process of which a locking element 16 is formed in the form of a flexible tongue. The left end wall 11 adjoins the side wall 17, having the bottom valve 18 and the petal 19. In the upper part of the side wall 17, the elements 20, 21, 22, 23 and 24 are made in a mirror image with respect to the upper part of the side wall 2. To the side wall 17 adjoins the right end wall 25, having a lower valve 26 and a petal 27. Top valve 28 with tongue 29 and slot 30

made similar to the upper valve 14 of the left end wall 11. The right end wall 25 is adjacent to the valve 31, designed to increase stiffness

side wall design 2. Depending on the configuration of the portable products, various auxiliary packaging tools are inserted into the inside of the carton in the form of cardboard grids (for juices, etc.), shaped liners, cardboard linings, etc., ensuring reliable fixation and protection products inside the carton during transportation.

5 Carton box is assembled as follows.

Along the inflection line 1, the left end wall 11 is bent at a right angle relative to the side wall 2, and the side

0, wall 1 relative to the left end wall 11. The right end wall 25 is bent at a right angle relative to the rear wall 16, and the valve 31 is bent relative to the right end wall 25 through an angle of 90 °.

5 The valve 31 is attached to the inner surface of the side wall 2. When assembling the bottom (Fig. B), the bottom valve 3 of the side wall 2 is folded at a right angle. Then the valve 18 of the side wall 17 is folded under the straight

0 angle, and its petal 19 goes into the interior under the lower valve 3. The valve 12 of the left end wall 11 is bent at a right angle, and its petal 13 is driven inside the inside of the valve 18, Valve 26 of the right end wall 5 is bent under the right my angle, and its petal 27 are driven inside the valve 18. To increase the strength, the adhesive tape 32 is applied to the bottom (fig. b) and the end walls 11 and 25 (figure 4 and 5) from outside. cardboard box covers. Along the bend line 1, the upper valve 5 of the side wall 2 and the valve 20 of the side wall 17 are bent at a right angle. Valve 6 and 21 are folded over

5 line of inflection 1 (figure 2) in a vertical plane. Figured protrusions 9 and 23 dock tightly to one another without gaps. The slots 15 and 30 of the upper valves 14 and 28 are passed through twin curly

0, the protrusions 9 and 23 of the vertical part of the lid formed by elements 6 and 21. The working end of the locking tabs 16 and 29 is bent outward from the slot 15 and 30, and then under the action of elastic force, try to take

5, the initial position j enters into the interior of the horizontal open slots 10 and 24, ensuring a reliable closing of the lid.
