Abstract
Abstract The process has a first phase of temporary subdivision of a container in a plurality of sectors, each assigned to contain a powder of different characteristics, through means of temporary subdivision, a second phase of filling such sectors, a third phase of partial pressing operation of such powders, a fourth phase for removing said means of temporary subdivision and a fifth phase of final pressing. The above process is executed with an apparatus including a frame which, by means of tubular cells, defines said subdivision sectors of the container. Said cells are connected to means for the feed and the controlled delivery of said powders and pressing pistons translate in them.

Claim 3
Dependent Claim
115 words
Apparatus for producing packages of cosmetic products by temporarily subdividing a container during loading and packing steps, comprising: a movable frame with a height that is much greater than the height of a container to be filled with cosmetic powders and having a peripheral outline which coincides with the outline of a storage cavity for the powders of the container, which frame is subdivided into a plurality of tubular cells, each cell being connected to means for feed and controlled delivery of a cosmetic powder and in which translate pressing pistons, said apparatus further comprising a further pressing piston with a peripheral outline which almost coincides with the outline of the cavity of the container.
Claim 4
Dependent Claim
115 words

Claim 5
Dependent Claim
26 words
Apparatus according to claim 2, wherein said frame is formed by an upper portion and by a replaceable lower portion connected by means of a flange.
Claim 6
Dependent Claim
35 words
Apparatus according to claim 2, wherein said tubular cells are equipped with an aperture which allows the passage of said feed and controlled delivery means of the powders even during the translation of said frame.
