Abstract

1. A container having a body portion (1) which is preferably hollow-cylindrical in the mouth region (1') and which is provided with an edge rolling (2, 3, 5), thereby forming a hollow bead (2), which edge rolling (2, 3, 5) is turned over outwardly and projects downwardly and is formed at the lower end as a support (5) for a tool or the like for lifting off a cover (6) which in particular is provided with a seal (10) and can be fitted on to the container, the edge rolling being adapted to receive the cover, characterised in that the container body portion (1) ist of a slightly conical shape in the lower region (1"), that the lower end of the edge rolling (2, 3, 5) thereof is also formed as a stack support (7) on the container for the releasable, interfitting arrangement of a plurality of identical containers, and that, between the hollow bead (2) and the supports (5, 7), the edge rolling (2, 3, 5) is provided with a constriction (3) forming an outwardly open annular space (12).

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an edge wrapper in which the barrel is folded back outwardly at a distance from the container barrel while forming a bulge within the opening area and projects downward. The present invention relates to a container of the type having an edge wrap which at the lower end is provided with an engagement surface for a tool or the like serving to lift the lid.

Containers of the type described above are known (see US Pat. No. 2,444,591).

In known containers of this type, a lever-like tool mounted on the container body is used to lift the lid which partially surrounds the edge wrap of the container body. The tool engages in an annular chamber which is open towards the bottom of the edge wrap of the container and is supported there under the folded edge wrap. By pivoting this lever-like tool, the lid is released from the container body, first in one place and then in its entirety. Containers of this type cannot be stacked because their bodies are formed as hollow cylinders. In order to be able to stack such containers one above the other, an outwardly bulging stacking ridge is formed in the container body in the transition region from the hollow cylindrical part to the hollow conical part. be done. This stacking ridge has the disadvantage that it is not possible to completely empty the contents present in the container due to its provision.

The container according to the invention does not have such a ridge.

The underlying problem of the invention is to design containers of the known type described above in such a way that they can be stacked one above the other with other containers of the same type.

This problem is solved according to the invention, in that the container body has a slightly conical shape in its lower region, and a number of containers with the same lower end of the edge roll are stacked in a manner that allows them to be releasably inserted into each other. This problem is solved by the fact that the container is designed to serve as a stacking and placing surface for the containers when the container is placed on the container.

According to the invention, as described above, this problem is solved satisfactorily in a simple manner by special shaping and shaping of the edge wrap as a stacking and resting surface. This is because such a container takes up less space when being transported from the manufacturer to the user.

Advantageously, the convoluted part is provided with a constriction forming an outwardly open annular chamber between the first bulge and the second bulge.

This is because the edge wrap is thereby reinforced.

Furthermore, it is advantageous to design the lower end of the edge wrap of the container body as a flat stacking surface.
This is because when transporting the containers from the manufacturer to the user, any damage to the upper edge area of the container body is avoided even if these containers are stacked one on top of the other to save space; It is also possible to configure the underside of the engagement surface, which serves as a pry rest for simple tools, to serve as a stacking and resting surface.

The invention will be explained in more detail below with reference to exemplary embodiments illustrated in the accompanying drawings.

In particular, the container body 1, which has a hollow cylindrical design in the opening region 1', is slightly conical in its lower region 1''.This container can therefore be inserted into one another with another identical container. It is possible to store and transport in a stacked state.The edge wrap of this container body has a curved opening extending outwards from the somewhat hollow cylindrical region 1'. It is formed of one expansion and expansion part 2, a constriction part 3 that continues downward substantially parallel to this area 1', and a second expansion and expansion part 4.This second expansion and expansion part 4 has a lid. An engagement surface 5 is formed as a pry rest for a simple tool used for opening 6, and a stacking surface 7 for arranging a number of containers in one another. In this stacked state, this stacking and resting surface 7 rests on the upper edge region 8 of the first bulge 2 .
In this case, the conicity of the hollow conical part or lower region 1'' of each container is such that these parts do not come into contact with each other in a stack of a number of containers, that is, so that no mutual clamping occurs. It is set.

As is clear from FIG. 1, the inner annular surface 9 of the lid 6 does not have to rest against the inner wall of the hollow cylindrical section or region 1' of the container body 1. Because,
An elastic sealing substance 10 or packing is provided between these parts, and a bulging part 11 of the lid edge rolling part is formed by the constricted part 3 and extends outward as shown by the dashed line. This is because the annular chamber 12 is open and deformable toward the inside of the annular chamber 12 that exists between the two bulging portions 2 and 4. This annular chamber 12
It is possible to pivot the inwardly pushed bulge 11 with a screwdriver, a peg or similar tool supported on the engagement surface 5, thereby removing the lid 6 from the container body 1. After removing a portion of the container contents, the lid 6 is again pressed against the container body 1 to be fixed.

As is clear from FIGS. 2 to 7, the engagement surface 5 for a simple tool serving to open the lid 6 can be formed as one of the two annular parts 13 of the flat annular part. These two flat annular surfaces 13 also act as engagement surfaces 5 and stacking and placing surfaces 7 (first
(Fig. 2). When the mounting surface is formed in the second bulging portion 4, which is a hollow portion, the lower leg portion of the second bulging portion 4 may be provided at a more inclined angle than the leg portion in the embodiment shown in FIG. It is possible (Figure 3). In such a case, it is advantageous to provide at the lower end of the lower leg of the second bulge 4 another, relatively small cross-section, upwardly directed involute 14 . As a result, the second bulging portion 4 is reinforced, and damage to the upper edge 3 of the second bulging portion 4 of the container body that exists above and below when the containers are stacked one by one is avoided. Ru. In the embodiment according to FIG. 5, the lower second bulge 4 has only a relatively small cross-section, and this second bulge 4 has an engaging surface 5 and a seating surface 7'. is also formed. In the embodiment according to FIG. 6, these two support surfaces 5, 7' have a large distance from each other, while FIG. 7 shows a seventh embodiment according to the invention, which corresponds approximately to the embodiment according to FIG. However, in this embodiment, the engaging surface 5 has a winding portion 1 having a relatively small cross section.
5 is formed, and this winding corresponds to the winding 14 of the embodiment according to FIG.
