Dispenser for dispensing liquid substances or substances in the form of cream or paste.

摘要

A dispenser (10) for dispensing liquid substances or substances in the form of cream or paste, comprising a pump (1) in which in addition to the non-return valve (17), the elastic means for returning the piston (3) into its rest position following the operation of the dispensing knob (10) are also of plastics material, and consist of a skirt (4A) which deforms elastically when the knob (10) is pressed. To make the dispenser (10) completely salvageable, all its constituent elements are of one and the same plastics material, which is of a type from which both substantially rigid pieces and substantially elastically deformable pieces can be formed. Such a plastics material is for example polyethylene. <IMAGE>
