Abstract: The present invention relates to a device for distribution and/or controlling the discharge of unitary products, and for simultaneous in-situ treatment of the atmosphere of a container onto which it is fitted. The device comprises a lower surface provided with an entry opening, an upper surface provided with at least one main distribution opening, a guiding surface for the products to be distributed, and a means of securing the device. The device is made from a thermoplastic material comprising at least one thermoplastic polymer and at least one agent for treating gaseous pollutants present in the atmosphere of the container, by reaction with and/or adsorption of at least one existing gaseous pollutant and/or desorption of said agent in the atmosphere of the container.

Abstract: The present invention relates to an assembly for the storage and distribution of solid loosely packed products unit by unit. The assembly generally comprises a storage container, a sealing means and a discharge control device inserted into the neck of the container to permit the passage of the products to be distributed. Inviolability and sealing of the container are achieved by means of a peelable heat seal, sealed thermally onto at least one surface defined by an annular, peripheral surface of the neck of the container and/or all or part of an upper surface of the device and/or a surface of a distribution opening.

Abstract: A dehydrating plastics material composition of high moisture-absorption capacity, comprising:A) 50% to 80% by weight of one or more compatible thermoplastic or thermosetting polymers;B) 20% to 50% by weight of one or more dehydration agents;C) 2% to 8% by weight of one or more elastomers; andD) 1% to 4% by weight of fibers of lengths lying in the range 0.5 mm to 4 mm, the fibers being selected from: synthetic fibers, vegetables fibers, and animal fibers.A method of preparing such a composition.A package or container whose inside surface is constituted by a plastics material of the above composition.
