Abstract
Abstract The invention relates to a plastic packing having multiple compartments for liquid and solid products having a joint common to both compartments constituted by at least two sheets of polymer material, one of which ruptures internally along a longitudinal axis, without the external walls of the packing rupturing, when an external pressure is applied to one of the compartments. The packing of the invention enables the separate storage, in different compartments, of various incompatible substances, while enabling them to be mixed just before use, after rupture of the internal portion of the joint separating the said compartments. The packing of the invention in particular enables the preparation of novel and advantageous devices designed for the deodorizing of enclosed spaces.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
63 words
Plastic packing having multiple compartments for liquid and solid materials, characterized in that it comprises a joint common to both compartments constituted by at least two sheets of polymer material, one of which is polymer foam material and ruptures internally along a longitudinal axis without the external walls of the packing rupturing, when an external pressure is applied to one of the compartments.
Claim 2
Dependent Claim
63 words
Plastic packing having multiple compartments for liquid and solid materials, characterized in that it comprises a joint common to both compartments constituted by at least two sheets of polymer material, one of which is polymer foam material and ruptures internally along a longitudinal axis without the external walls of the packing rupturing, when an external pressure is applied to one of the compartments.
Claim 3
Dependent Claim
52 words
Plastic packing having two compartments as claimed in claim 1, characterized in that the said compartments have different volumes and in that the smaller of the two is housed within the larger and in that the rupture of the smaller compartment is caused by an external pressure applied to the larger compartment.
Claim 4
Dependent Claim
51 words
Plastic packing having multiple compartments as claimed in claim 1, designed to contain perfumes, insecticides or other active substances, characterised in that at least one of the walls of the said compartments comprises a sheet of polymer material enabling the external diffusion of the said perfumes, insecticides or other active substances.
Claim 5
Dependent Claim
42 words
Plastic packing having multiple compartments as claimed in one of claims 1 to 3, characterized in that the sheet of polymer foam material is polyethylene, polypropylene, polyamide, polyvinylchloride, polyester or polyestyrene foam and has a thickness of between 0.005 and 0.2 mm.
Claim 6
Dependent Claim
15 words
Plastic packing having sterilisable multiple compartments as claimed in one of claims 2 to 3.
