Container having a stacking support shaping

Abstract

A container having a bottom and a cylindrical or conical sidewall attached to the bottom, wherein the sidewall preferably comprises a rolled rim at its upper edge opposite to the bottom and is produced from a paper- or carton material, wherein at least a first shaping is provided into the sidewall in a first height, and wherein the shaping extends at least partially over the perimeter of the sidewall. A process for the production of a container with a bottom and a conical or cylindrical sidewall is also provided, wherein the bottom and the sidewall are made from a paper- or cardboard-material and a first circumferential shaping is inserted into the sidewall.

Claims

1. A container comprising: a bottom; a cylindrical or conical sidewall attached to the bottom, wherein the sidewall includes a rolled rim at an upper edge opposite the bottom and is produced from a paper or cardboard material, wherein the sidewall includes an inner side and an outer side; and a first shaping provided into the sidewall at a first height so that the first shaping is positioned close to the bottom of the container, wherein the first shaping extends at least partially around a perimeter of the sidewall; wherein the first shaping includes a first flank and a second flank that are compressed in height such that the first shaping is essentially flat; wherein the first shaping includes a first portion that extends from the sidewall in an inward direction and beyond the inner side of the sidewall and a second portion that extends from the sidewall in an outward direction and beyond the outer side of the sidewall, wherein when the container is a first said container, the first portion of the first shaping serves as stacking support for a second said container when the second said container is partially inserted into the first said container.

2. Container according to claim 1, wherein the first flank is located at least partially above the second flank.

3. Container according to claim 1, wherein a second compressed shaping above the first shaping is provided, which extends at least partially around the perimeter of the sidewall.

4. Container according to claim 1, wherein the first and second flanks of the first shaping are at least partially fixed together.

5. Container according to claim 1, wherein the sidewall is coated with a heat-sealable material.

6. Container according to claim 1, wherein the first shaping forms a high-frictional grip area.

7. Container according to claim 1, wherein the second portion serves as form-fit-means to secure the second said container to the first said container.

8. Container according to claim 7, wherein the second portion of the first shaping of the first said container is in form-fit-connection with a second shaping of the second said container.

9. Container according to claim 1, wherein the first portion of the first shaping is at least partially located above the second portion of the first shaping.

10. Container according to claim 1 further comprising a third flank, wherein the first portion of the first shaping includes the first and second flanks, and wherein the second portion of the first shaping includes the second and third flanks.

11. Container according to claim 10, wherein the first flank is located at least partially above the second flank, and wherein the second flank is located at least partially above the third flank.

12. Container according to claim 1, wherein the first portion of the first shaping of the first said container supports a lowermost end of the second said container when the second said container is at least partially inserted into the first said container.

Description

DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

(1) FIG. 1 is a partial sectional view of two stacked containers.

(2) FIG. 1A is an enlarged partial sectional view of FIG. 1 illustrating a first shaping of one container in form-fit connection with a second shaping of another container.

(3) FIG. 2 illustrates the compression process of the shaping.

(4) FIG. 3 illustrates the compression process of the shaping.

DETAILED DESCRIPTION OF THE INVENTION

(5) FIG. 1 shows two containers 1, which are stacked. Each container comprises a conical side wall 2, which has at its upper end a rim 8 and at its lower end a bottom 3 which is attached, preferably sealed, to the side wall. Above the bottom 3 and relatively close to the bottom, a first shaping 6 is inserted into the side wall. This inserting 6 comprises a first portion 6.1 which extends from the inner surface 2.1 of the side wall and a second portion 6.2, which extend from the outer surface 2.2 of the side wall. Each portion 6.1, 6.2 comprises two flanks 6, which are preferably, at least essentially, parallel to each other, whereas at least two flanks, preferably two flanks 9 of each portion, are, at least locally, connected, preferably sealed or glued, together. The first portion 6.1 of the shaping 6 is preferably, at least partially located above the second portion 6.2 of the shaping. Both shapings have preferably a common flank, which is the longest flank of the first shaping 6. Above the first shaping, a second shaping 7 is introduced into the side wall 2. After one container has been inserted into a second container, the first portion 6.1 preferably builds a stop, which limits the degree by which the second container can be inserted into the first container. The second portion 6.2 form-fits together with the second shaping 7 so that a certain force is needed to remove one container from the other. This form-fit is depicted in the enlarged view of FIG. 1A. It can be clearly seen that at least the tip of the second portion 6.2 of the first shaping 6 lies against the lower edge of the second shaping 7 and thus forms a form-fit. During insertion and/or removal of the first container in/from the second container, the second portion 6.2 and/or the second shaping 7 slightly deform, preferably elastically, so that the first container is locked in or can be taken out of the second container.

(6) FIGS. 2 and 3 show the compression of a first shaping 6 by a mandrel 4 and a pusher 5. This pusher lies against the bottom and/or the lower tip of side wall 2 and its upward movement compresses the side wall as depicted in FIG. 3. During this compression, a shaping 6, which was initially bended inwards, is shaped into a first inward directed portion 6.1 and a second outwardly directed portion 6.2.
