Abstract:
1. A vacuum breaker for use with a container, comprising: a housing including first and second housing parts cooperating so as to define an internal cavity and a flow path communicating with the cavity and extending through the housing; a control member defining a flow passageway communicating with the flow path, the control member partially disposed in the cavity and having a resiliently collapsible valve part protruding externally from the internal cavity and free of the housing and communicating with the flow passageway so as to close the flow passageway and to automatically open when the ambient pressure is reduced; and the housing and the control member cooperating so as to locate the externally exposed protruding valve part within the container associated therewith so that the protruding valve part, in response to changes in ambient pressure surrounding the valve part, maintains the flow passageway closed when the ambient pressure exerted thereon is positive, automatically opens when the ambient pressure in the container is reduced to thereby break the resulting vacuum, and automatically re-closes when the ambient pressure in the container equalizes with the external ambient pressure.
