Problems solved by technology

However, due to the deformation of the aluminum foil surface during the deep drawing process, it is impossible to perfectly control the final appearance of the capsules, and different capsules may have irregular appearances
In addition, some experiments have shown that when containers are randomly mixed, it is difficult for consumers to quickly distinguish between containers with different color combinations

Embodiment Construction

[0035] figure 1 and figure 2 An aluminum container according to the present invention is shown. The aluminum container 1 is made of aluminum foil which has been stamped / molded to form the container body 7 . The end of the container body has a flange-like rim 4 and a bead 2 . The opening of the container is closed by a lid 3 welded on a flange-like rim 4 . The product stored inside the container 1 is not shown. According to the invention, the aluminum foil used to make the container has two sides 61, 62 which have been given different coloring treatments. Due to this difference in handling, the container has a bead 2 of a different color than the container body 7 and the flange-like rim 4, said color being in figure 1 and 2 Expressed in pointillism.

Abstract

The invention concerns an aluminium container (1) issued from the process of stamping / deep drawing an aluminium foil (6) to form a container body (7), cutting the edges of the container body, curling said edges on the exterior side of the container body in order to form a curled edge (2) and closing the container body by a foil / lid / membrane (3) wherein the colour of the curled edge is different from the natural colour of the aluminium foil.

Description

[0001] This application is a divisional application of an invention patent application with an application date of September 17, 2009, an application number of 200980137495.X, and an invention title of "manufacturing process for two-color aluminum containers". technical field [0002] The invention relates to an aluminum container, in particular to an aluminum beverage capsule. Background technique [0003] Containers made of aluminum foil are very common and have been known for a long time. Such containers are frequently used in the field of the food industry for storing and dispensing food ingredients. [0004] Such aluminum containers are well-suited for use in the field of beverage production: they are in the form of capsules containing beverage ingredients designed to be inserted into beverage manufacturing devices where liquid enters the capsule in order to interact with the beverage ingredients Capsules discharge beverages. Such capsules can contain different types ...
