Abstract

1. A container made of corrugated cardboard, comprising a box and a vertical multi-faceted insert placed therein adjacent to its inner walls, formed from a sheet of cardboard with fold lines for sequential formation of faces, characterized in that the vertical insert is provided with at least one an additional face placed between two adjacent faces in one of the corners of the box. 2. A container according to claim 1, characterized in that the additional face is made at an angle of 30 to the width of the liner.

Description

Corrugated cardboard packaging.

The invention relates to the field of containers for storage and transportation of products subjected to mechanical damage, when it is installed in a stack.

Known containers of corrugated cardboard, made in the form of a box with auxiliary packaging means, for example, an insert for reinforcing the sides and ends of the box (Handbook "Transport packaging, Moscow, publishing house" Transport, 1989.).

The well-known "Container made of corrugated cardboard for transporting products according to the patent of Russia No. 2063914, IPC-7 B65D 5/50, published on July 20, 1996

The container contains a box equipped with auxiliary packaging: shell, gaskets, shock absorbers. Between the gaskets, one of which is located on the bottom of the box, at least one vertical multi-faceted insert is located on the base of the product.

The vertical insert together with the upper gasket and the side walls worn on the shell transmits the forces acting vertically on the packaging onto the solid base of the product being packaged, i.e. ensures safety during transportation and handling of products of complex external configuration having fragile protruding parts.

Disadvantage. The implementation of the liner in the form of a multifaceted vertical column installed between the gaskets, does not provide hardening containers

in general, along the axis of gravity from a stack of boxes filled with products.

Corrugated cardboard boxes with liners placed in them, given in GOST 9142-90 “Corrugated cardboard boxes, general technical conditions, were selected as a prototype.

Corrugated cardboard packaging consists of a box and a vertical tetrahedral insert placed therein adjacent to its inner walls, formed from a sheet of corrugated cardboard or similar material with fold lines for sequential formation of faces.

Disadvantages: the tetrahedral design of the vertical liner does not provide high strength containers filled with products that are easily subjected to mechanical damage during storage and transportation of it with a stack.

The objective of the invention is the creation of containers from corrugated cardboard with increased strength along the axis of action of gravity from a stack of boxes.

To solve the problem, in a container made of corrugated cardboard containing a box and placed in adjoining to its inner walls a vertical multi-faceted insert formed of a sheet of cardboard with fold lines for sequential formation of faces, according to the invention, the vertical insert is provided with at least , one additional face placed between two adjacent faces in one of the corners of the box. An additional face can be made at an angle of 30 ° to the width of the liner.

The use of at least one additional face in the container increases the strength of the container by increasing the number of stiffeners, i.e. increases resistance to compression or strength when stacking boxes with easily deformable products.

The claimed invention has differences from the prototype, i.e. meets the criterion of "novelty and does not follow explicitly from the studied prior art. In addition, the proposed device can be manufactured on an industrial scale and find application in the manufacture of corrugated cardboard containers, i.e. characterized by the criterion of "industrial applicability.

The essence of the claimed technical solution is illustrated by drawings, where in FIG. 1 shows the proposed container, a top view, in FIG. 2 is a top view of the insert, FIG. 3-scan liner.

Corrugated cardboard packaging contains a box 1, a polyhedral vertical insert 2 adjacent to its inner walls adjacent to its inner walls and formed from a sheet of corrugated cardboard or similar material with fold lines “a for sequential formation of faces 3. The vertical liner is provided with at least one additional face 4, placed between two adjacent faces in one of the corners of the box. An additional face 4 can be made at an angle of 30 ° to the width of the liner.

. In a specific embodiment, the liner 2 is equipped with three additional faces 4 located at the three corners of the box 1. Three faces three stiffeners - made at an angle of 30 ° relative to the width of the box. The insert 2 is made of a sheet with a length of 1580 mm, a height of 285 mm. the formation of faces along the fold lines "a. One of the end faces of the liner "b consists of

two lap valves, for example, in the size of 62 mm. This ensures a tight fit of its outer surface to the inner surface of the box 1 and the evenness of the inner surface of the liner in contact with the filled product. The presence of seven faces is the best option, maximizing the hardening of the container with its maximum filling.

The proposed packaging is used as follows. The successive formation of faces along the fold lines a forms an insert of a 7-sided shape, which is placed inside a box 1 having dimensions 570x228x285.

This liner provides an increase in tare strength by increasing the number of stiffening ribs of the liner. When testing containers under mechanical load by dynamically squeezing between parallel planes of boxes installed by the stack, along the action of gravity it is noted:

within 15 minutes, a box taken as a prototype, with a traditional insert (tetrahedral), filled with loose material, such as pasta, withstood the weight of 190 kg until the first mechanical damage. The proposed container with a 7-sided insert insert has withstood the weight of 275 kg. Using the insert according to the invention allows to increase the safety margin by 45%.

Claim.

1. A container made of corrugated cardboard, containing a box and a vertical multi-faceted insert placed in it adjacent to its inner walls, formed of a sheet of cardboard with fold lines for successive formation of faces, characterized in that the vertical insert is provided with at least one additional a face placed between two adjacent faces in one of the corners of the box.

2. A container according to claim 1, characterized in that the additional face is made at an angle of 30 ° to the width of the liner. Corrugated cardboard packaging
