Abstract:
Manually operable pump for dispensing atomized liquids, the pump having passageways enabling air to enter the container on which the pump is mounted, when a vacuum forms in the container on dispensing liquid through the pump.
Abstract:
A pushbutton for a pump or valve for dispensing fluid substances contained in a container on which the pump is mounted. The main portion of the pushbutton has a substance dispensing nozzle and elements for securely retaining said main portion on the pump or on a body rigid therewith. The pushbutton also has an upper or movable portion with a seat for sealedly housing the free end of the pump stem. The two pushbutton portions can translate one relative to the other and are connected together by tubular appendices which are inserted into and sealedly translatable one within the cavity of the other and are connected to said stem seat and to said nozzle respectively.
Abstract:
A manually operable dispensing pump for application to liquid containers, in which the pump has a hollow stem which projects from a hole provided in a flange forming part of the pump, the stem having a profiled annular part which seals against a profiled seat on the flange when the pump is in its rest state, there projecting all about said flange seat a skirt within which the annular part of the stem slides and seals.
Abstract:
An operating pushbutton for dispensing pumps for fluid substances contained in containers on which the pumps are mounted. The pushbutton has an end portion which can translate on a portion thereof applicable to the pump stem, such that when a pressure is exerted on said end portion it undergoes a free translation before causing the other pushbutton portion to move, hence preventing accidental dispensing of the fluid substance.
Abstract:
Manually operated invertible pump for dispensing atomized liquids, the pump having a very compact structure and an aperture which can be intercepted by the pump piston to control liquid entry into the pump when this is in a downwardly inverted position.
Abstract:
Manually operable invertible pump for dispensing atomized liquids, the pump having a very compact structure and a flexible diaphragm valve for controlling liquid entry into the pump when this is in an inverted or partly inverted position.
