Dispensing structure with dispensing valve and barrier penetrator
First Claim
1. A dispensing structure for a container that has an opening to the container interior, said dispensing structure comprising:
- a membrane for occluding said container opening; and
a cover for extending around said container opening over said membrane, said cover including(a) a peripheral frame,(b) a panel that (i) defines a dispensing aperture, (ii) is connected with said frame, (iii) is normally biased to an outwardly convex configuration as viewed from outside said cover, and (iv) accommodates movement of said panel to a self-maintained, inverted, inwardly concave configuration,(c) a dispensing valve in said cover across said dispensing aperture, and(d) a penetrator extending from said panel inwardly of said dispensing valve for penetrating said membrane when said panel is in said inwardly concave configuration.

Abstract
A dispensing structure is provided for a container that has an opening to the container interior. A membrane initially occludes the container opening. A cover extends over the container opening and over the membrane. The cover has a peripheral frame and a panel that is connected to the frame. The panel has a dome-like, outwardly convex configuration defining a dispensing aperture and is normally biased outwardly. The panel can be moved to an inverted, inwardly concave configuration. A dispensing valve is disposed in the cover across the dispensing aperture. A penetrator extends from the panel inwardly of the dispensing valve for penetrating the membrane when the panel is in the inwardly concave configuration.
