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.
