Field of technology

The utility model refers to a metal container made of sheet metal, intended for storage and transport of products produced by both the food industry and the chemical industry.

BACKGROUND OF THE INVENTION

Sheet metal containers with a wide variety of shapes are known. Containers of the type having a tubular body with an open upper end, walls and bottom are widely used. During storage and transport, they fit together (stacked), often jamming so tightly together that their separation is then a serious problem. Typically, this manipulation requires two people and the application of significant force or aids, as a result of which deformations and damage to the containers are possible. To solve this problem, various prior art solutions of containers of the type are known from the prior art.

EP 0471918 B1 describes a metal container, having a conical body with walls and a round bottom fixed to the lower end of the walls by a double-bent outer extruded bert. The upper peripheral edge of the container is formed by the outwardly curved upper end of the walls. Parallel to the upper edge, a protruding reinforcing rib is made in the walls of the container, serving as the upper metal container and as a limiting rib, which rests on the upper edge of the lower metal container when at least two empty containers are placed one in the other. another.

In order to carry out the stacking and subsequently to facilitate the separation of the containers. the walls have an inwardly sloping section extending from the reinforcing (limiting) rib to the bottom, and above the reinforcing rib the walls of the container are cylindrical to the upper edge. The container is equipped with a reusable lid.

Since the bounding rib on the container of EP 0471918 B1 is a protruding ring, when stacked with other containers, the lower surface of the rib of the upper container rests tightly along the entire length of the upper edge of the lower container. Also, at the point of support, the diameter 5 of the body of the upper container is the same as the diameter of the body of the lower container. As a result, the possibility of jamming the containers in each other is not eliminated, especially when a large number of containers are stacked. 10 ~

Technical essence of the utility model

The purpose of the utility model is to create a metal container of the type having a tubular body with an open top, walls and bottom, with 15 possibilities for easy stacking and subsequent seamless separation of containers by only one person, without the risk of receiving inadmissible deformations and injuries.

Also, an important goal of the utility model 20 is to create a metal container suitable for closure with a reusable lid or with a non-detachable lid.

In a preferred embodiment, the inwardly inclined portion of each wall has at its lower end an inwardly inclined zone located at the bottom, so that the dimension of the bottom together with the double-curved outer bert is smaller than the dimension outlined. from the mental continuation of the sloping sections of the walls.

Preferably, the two reinforcing ribs 10 in the walls and the restraining ribs at the corners of the container have a V-shaped cross section.

For additional convenience and convenience in handling the container, a handle is provided, which is mounted to the two supports with the possibility of retracting between the reinforcing ribs in the stacked position of the containers and for pulling and turning upwards when separating them.

In one embodiment, the supports have a cylindrical body, one end of which is fixedly attached to the walls of the container, and its free end is provided with a flange.

Preferably, the handle is made of plastic with a generally rectangular cross-section, with a 25 longitudinal rectangular hole with round widenings at both ends at both ends. This configuration of the longitudinal opening allows the handle to be retracted or pulled out depending on the handling of the container. 30

The metal container, object of the utility model has a very wide application. Depending on the contents, the container can be closed with a lid for repeated opening and closing or with a non-detachable lid. 35

According to the utility model, two variants of the layout of the upper peripheral edge of the container have been developed according to the type of lid that will be used to close the container. 40

In a variant of a container with a reusable lid, the upper peripheral edge is an outwardly curved edging board having an upper straight portion extending into the bent downward and inwardly helical portion, the right portion being 45 parallel to the wall of the container. Immediately below the spiral part in the walls of the container is formed an outwardly engaging groove, having an angular profile of different lengths, the shorter side facing the spiral part and the angle at the top being greater than 90 °.

The gripping groove is designed to accommodate a corresponding gripping convex edge formed in the side walls of a reusable lid.

In the case of a container with a non-detachable lid, the upper peripheral edge of the container is a horizontal bent bent outwards.

After placing the non-detachable lid on the container, the peripheral edge of the lid and the horizontal bert of the container are connected by a double-bent bert pressed against the walls.

The metal container, according to the utility model, has the following advantages.

Due to the arrangement of the restraining ribs in the inclined section of the walls, a gap is provided between the wall of the upper container and the wall of the lower container when placing the containers in each other. In addition, the bearing surface of two adjacent containers is reduced, as the restraining ribs are made only in the area of the corners. These two design features of the utility model eliminate the possibility of jamming the containers into each other. The user can easily separate the containers without the need for additional help or resources.

The presence of a second reinforcing rib in the vertical section of the walls contributes to greater stability of the container.

The handle mounted axially to the walls, with the possibility of retraction between the two reinforcing ribs, provides additional convenience and convenience when handling the container.

Another, no less advantage of the utility model is the rectangular shape of the cross section of the container, which allows tight arrangement of the containers next to each other during storage and transport and maximum use of volume.

Thanks to the two layout options of the upper peripheral edge, the container can be closed with a reusable lid or with a non-detachable lid.
