  • Patent number: 5363993
    Abstract: 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 structure 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.

  • Patent number: 5348194
    Abstract: The atomizer bottle (10; 110), operable by manual squeezing, comprises in addition to the actual bottle (12, 112) containing the liquid to be atomized an atomizer capsule (22; 122) which closes the mouth (20: 120) of the bottle (12; 112). In the capsule (22; 122) there is inserted an atomization insert (26; 126) comprising a nozzle (27; 127) from which the atomized liquid emerges. The atomizer bottle (10; 110) also comprises a conventional pump (32; 132) with the relative dip tube (60; 160). The pump (32; 132) is enclosed within the bottle (12; 112) and is operable by axially pressing a hollow shaft (30; 130) projecting from it. The hollow shaft (30; 130) of the pump is rigid with the capsule (22; 122), and the interior of the shaft (30; 130) communicates with the nozzle (27; 127).
