Abstract

Improvements in the construction of elastomeric pumps and check valves, of the type that are attached to containers to expel the liquid contained in small doses, characterized in that they are constituted by a base element that has a surface through which two are projected mouths, and an integral elastomeric element comprising a hidden section with a peripheral flange that sits against said surface defining with it a closed chamber communicating with said two mouths, at least one dividing wall in said hidden section and forming an integral part with the same, said dividing partition having an edge that rests elastically against the surface of said base element between said mouths, thereby dividing said chamber into two compartments, each of which communicates with a mouth, said partition being in relation to said partition. Inclined with each line that is (a) tangent to that surface where it is in contact with said edge, and (b) normal with respect to said edge.
