Abstract

The invention relates to the manufacture of containers and packaging, in particular to folding boxes for storing and transporting industrial goods and confectionery. The purpose of the invention is to increase the rigidity of the container. The container is formed from a flat billet, divided by bending lines into areas forming a lid with a locking protrusion, a front wall, a bottom, a back wall, a supporting strip with slots, two end walls connected with one side to the workpiece and fitted with valves located from two opposite sides of each end wall. The end walls of the container are tapered upward, inclined towards the inside of the container and offset from the side edges of the front and rear walls. The end walls are connected to the valves by means of triangular sections between them. The invention provides an increase in stiffness and compressive strength due to the fact that the valves have internal backing from the side walls installed obliquely inside the container, in addition, the valves are clamped between the planes of the triangular sections and the front or rear walls, and the movement of the edges of the valves parallel to the bottom plane is limited tilting valves in relation to the bottom. 4 il.

Description

The invention relates to the production of containers and packaging, in particular to folding boxes for storing and transporting industrial goods and confectionery products, and is an improvement of the known folding containers according to the author. St. No. 1570957.

The aim of the invention is to increase the rigidity of folding containers.

Figure 1 shows the container, a general view; figure 2 - scan: on fig.Z - variant packaging; 4 - too, a fragment of a razvetka

Folding containers are formed from a flat billet of sheet material separated by break lines 1, some of which are fins, into sections forming a lid 2 with a locking lug 3, a front wall 4, a bottom 5, a back steak 6 and a support strip 7 with slot 8, the two end walls 9 and 10. are tapered upward and connected to one side with the workpiece. The end walls 9 and 10 are provided with valves 11 and 12, at least one of which has a tongue 13, provided with a grip through hole 14, forming a handle, and slots 15 are made on the edges of the container, where the tongues 13. are inserted during assembly. and 10 are connected to valves 11 and 12 by means of

located between them, the triangular sections, 16 and 17. Tara has flaps 18, covering its inlet. The tongues 13 can be provided at the ends with strips 19 entering the opposite slots 15 and 8 for laying 14 in the transport position. The end walls 9 and 10 are installed obliquely inside the container and offset from the side edges of the front and rear walls 4 and 6.

Tara is collected as follows.

Consistently relative to each other, they bend along the bending lines 1, the cover 2, the front wall 4, the bottom 5, the rear wall 6 and the support strip 7. From the billet obtained in this way, the end walls 9 and 10 are bent, and the end walls - valves 11 and 12, which are placed along the front 4 and rear 6 walls. The tabs 13 are inserted into slots 15 and 8, and the handles 14 extend the container. After installation into the container of the packaged product, the container inlet of the container is covered with flaps 18. And the triangular sections 16 and 17 are curved parallel to the inner surface of the valves 11 and 12. At the same time, the end walls 9 and 10 are inclined inside the container and the front 4 and rear 6 walls are inclined to a friend against the edges of the end walls 9 and 10. Close the lid 2 by inserting the locking protrusion 3 into the slot 8. The lid 2 is closed to keep the walls of the container from tilting.

When assembled, the container may have the shape of a truncated pyramid (figure 1). In another embodiment of the container, the upper parts of the front and rear walls are inclined to each other along an arc (FIG. 3).

In the described container, the valves have internal overpressure from the side of the end walls installed obliquely inside the container, besides that / o, the valves are clamped between the planes of the triangular sections and the front or rear walls, and the movement of the valve edges parallel to the bottom plane is limited by the inclination of the valves relative to the bottom. All this, together with the cross-section of the container that tapers towards the inlet, increases its rigidity and compressive strength. The narrowing of the inlet when the container is closed restricts the possible movement of goods inside the container, and its trapezoidal section reduces the volume of group pack: forging and increases the strength characteristics, allowing to increase the height of the stack. The inclination of the front and rear walls makes a smooth transition from the walls to the handles during the transfer of the container, which reduces the force of lateral compression of the container with the handles.

The invention allows to increase the rigidity and strength of the container.
