Abstract

The container (1) is intended for the separate storage of active compositions, especially of liquids or solutions, and for their subsequent mixing just before use.

It comprises at least three compartments (3, 4, 5) separated from one another by leakproof seams (6) of the material of the envelope (2), sealable inlet passages (7, 8), sealed transfer passages (10, 11) and a sealable outlet passage (9). The envelope is made of a polymerized and homogeneous flexible material which is chemically inert to each of said compositions and to their mixtures.

Claims

1. A container comprising a flexible envelope formed of a polymerized material, comprising three compartments for the separate storage of compounds of lipids, amino acids and sugars and their subsequent mixtures just before use, wherein the said container further comprises, in its upper part, two adjacent upper compartments situated at the same level, a third lower compartment located below and adjacent the two compartments, each compartment being provided with a sealable passage allowing for introduction into it from outside of a particular compound and to empty the contents from the third compartment, sealed and openable passage means connecting the two compartments to the third compartment for transferring the contents of the two compartments to the third compartment, said passage means comprising no more than a single passage between any of the compartments, the material forming the envelope being chemically and biologically inert with respect to each of the compounds and to their mixtures.

2. The container as claimed in claim 1, wherein the sealed transfer passages are breakable by hand.

3. The container as claimed in claim 1, wherein the material of the envelope in contact with compounds is polypropylene.

4. The container as claimed in claim 1, wherein the envelope is made up of a single sheet.

5. The container as claimed in claim 1, wherein the envelope is made up of a composite sheet.

6. The container as claimed in claim 1, wherein each of the two upper compartments are separately connected to only said third lower compartment solely by a separate single passage between each of the upper compartments and the third compartment.

7. The container as claimed in claim 1 wherein said two adjacent upper compartments are connected together solely by a single passage and only one of the two adjacent upper compartments is connected to the third lower compartment solely by a single passage.
