Zusammenfassung: | An aerosol valve movable from a closed position to an open position for retaining a product in, and spraying the product from, a container, comprising: a valve cup positioned on a first end of the container that orients the aerosol valve in the container, wherein the valve cup has a lip that defines a valve cup opening into the container; a valve stem disposed in the valve cup opening so that a first portion of the valve stem is disposed above the lip and a second portion of the valve stem is disposed below the lip within the container, the valve stem having an open first end, a closed second end and defining a longitudinal passageway therebetween with the open first end defining an outlet from the passageway of the valve stem, a side of the valve stem defining at least one inlet into the passageway near the closed second end; a resilient seal disposed in the valve cup opening between the valve stem and the lip, wherein the resilient seal comprises a seal body having a first portion disposed above the lip and a second portion disposed below the lip within the container, the seal body defining a seal body bore which the valve stem is disposed in and partially through; a ring knife disposed around the second closed end of the valve stem between the valve stem and the resilient seal, wherein the ring knife defines at least one arcuate shaped knife configured to mate with an outer surface of the valve stem and close the at least one inlet of the valve stem in a closed position of the aerosol valve; wherein force on the valve stem in a directions towards the container at least partially compresses the resilient seal and moves the at least one inlet past the arcuate shaped knife to allow product under pressure within the container to enter the inlet and travel through the longitudinal passageway and out through the outlet; and wherein upon release of the force on the valve stem, the resilient seal forces the valve stem back to the closed position wherein the arcuate shaped knife covers the at least one inlet of the valve stem.
L'invention concerne une valve d'aérosol qui peut se déplacer d'une position fermée vers une position ouverte, pour retenir un produit dans un récipient et pour en pulvériser le produit, et qui comprend : une coupelle de valve positionnée sur une première extrémité du récipient, qui oriente la valve d'aérosol dans le récipient, la coupelle de valve ayant une lèvre qui délimite une ouverture de coupelle de valve dans le récipient ; une tige |
