Abstract:
1. A non-refillable valve device comprising: a housing including an axially extending internal cavity, the internal cavity including a chamber extending to an end of the housing, the housing being securable to a container to facilitate fluid communication between the container and the housing chamber; a plug member secured within the housing chamber to provide a fluid flow passage between the container and the housing chamber when the housing is secured to the container; and an elastic sealing member disposed within the chamber, the sealing member being displaceable from a first position to a second position within the chamber; wherein the sealing member in the first position permits fluid flowing into the valve device to flow through the fluid flow passage and into the container, and the sealing member in the second position substantially prevents fluid flow through the fluid flow passage and into the container, and wherein fluid pressure exerted on the sealing member in the second position causes the sealing member to expand to permit fluid flow through the fluid passage from the container to the housing chamber.
