Container and linkage consisting of a number of containers
Container for packing of liquid, pasty or solid substances or small parts with a cup made of plastic, which is liquid-tight and can be sealed with a sealing film made of plastic. The container has a cover with a stable, plastic edge part, which can be detached from the cup and attached liquid-tight to the upper edge of the container, on the surface of which sealing film can be welded on liquid-tight.
1. A container for the packaging of liquid, pasty or solid substances or of small parts, in particular pharmaceutical or medical products, the container comprising:
a cup made of plastic having a cup wall with an inside, an outside, and an upper edge surrounding a top of the cup wall; and
a cover made of plastic being positioned on the cup in a liquid-tight manner, wherein the cover comprises:
an annular edge part surrounding and seated on the upper edge of the cup with a moulded interface between the edge part and the cup, the edge part having a level surface and a projection extending away from the level surface, the projection being positioned in contact with the outside of the top of the cup wall, the edge part having an inside edge that is flush with the inside of the cup wall;
a sealing film that is connected by a weld that is liquid-tight to only the level surface of the edge part to cover an opening in the edge part,
and wherein the cup is made together with the edge part of the cover in a two-component injection moulding process to provide the moulded interface that is liquid-tight and so that the cover is detachable and re-attachable to the cup.
2. The container according to claim 1 , wherein the edge part of the cover is connected liquid-tight to the upper edge of the cup by means of a tongue and groove connection in a re-attachable manner.
3. The container according to claim 1 , wherein the edge part of the cover is connected liquid-tight to an upper edge of the cup by means of a snap connection in a re-attachable manner.
4. The container according to claim 1 , wherein the edge part of the cover protrudes beyond the upper edge of the cup toward the outside.
5. The container according to claim 1 , wherein the moulded interface has at least one tamper-proof seal, which visibly changes an outer appearance when opening the cover for the first time.
6. The container according to claim 5 , wherein the tamper-proof seal has at least one component, which is separated or detached or that deforms when removing the cover for the first time.
7. The container according to claim 1 , wherein the cup wall is formed on an area toward the upper edge of the cup and toward the outside, thereby forming a spout.
8. The container according claim 1 , wherein the edge part of the cover is widened on a local level at one point thereby forming a pull tab to open the cover.
9. The container according to claim 1 , wherein the edge part of the cover has a hinge connection to the upper edge of the cup at one point.
10. The container according to claim 1 , wherein on the outside of the cup wall, in particular near the upper edge, there is a flattened area, which forms a type of undercut.
11. The container according to claim 10 , wherein in the flattened area, a groove is formed, which, in particular, runs parallel to the upper edge of the cup.
12. An assembly comprising a plurality of the containers of claim 1 arranged in a row, for packaging of liquid, pasty or solid substances or of small parts, wherein each container has the cup and the cover edge part, surrounding and seated on the upper edge of the cup and being positioned on the cup in a liquid-tight manner, where the cover edge parts of adjacent containers are respectively connected to each other on a local level via at least one thin spot made of the material of the edge parts.
13. The assembly according to claim 12 , characterized in that the at least one thin spot is a designed as bar.
14. The assembly according to claim 12 , characterized in that the at least one thin spot is a designed as an arched or folded plastic skin.
15. The assembly according to claim 12 , characterized in that the cups are manufactured together with the edge parts in a two-component injection-moulding process so as to form a moulded interface there between.
