Abstract
Disclosed are can taps for dispensing fluids from containers. The can tap has a housing with an inlet and an outlet, and a pin. The pin has a flow portion in fluidic communication with the inlet and the outlet of the housing. The pin may have a blunt depressor capable of operating a valve on the container. The flow portion of the pin allows fluid to flow between the housing and the pin. The can tap may have a gasket comprising a material having a hardness that prevents deformation of the container.
Claims20
A container comprising:
- a) a can top which comprises:
- i. a flat annular base section with an inner peripheral edge,
- ii. a male threaded tube, an open end contiguous with said inner peripheral edge, a distal end with an annular section, said annular section comprises an outer edge contiguous with said distal end, an intermediate planar section contiguous with an inner;
- upwardly curved section with an inner end forming said inner peripheral edge which is spaced above an upper surface of said planar section and forms a crown which defines a first central opening,
- b) an O-ring configured with upper and lower flat surfaces and defining a second central opening, said upper flat surface contiguous with said intermediate planar section and said lower flat surface defining an inner sealing surface,
- c) a valve comprises:
- (i) a tubular wall which comprises an internally linear surface which extends between an open end directly connected to and contiguous with said inner peripheral edge, an end wall closed to flow, and openings extending through said tubular wall, (ii) a spring, and (iii) a sealing plug axially movable within said tubular wall, said plug comprises a circular protrusion at a top end and a bottom end configured for seating said spring, said plug dimensionally configured with an external circumferential surface to permit flow between said external circumferential surface and said internal linear surface wall upon depression of said plug, and
- d) a can tap comprises upper and lower chambers separated by a throat section defining a third central opening, said lower chamber configured with female threads which retain an annular planar gasket defining a fourth central opening greater in dimension than said first central opening, and juxtaposed to said throat section, said can tap further comprises an actuating pin and distal depressor, said actuating pin independently movable relative to said can tap, wherein said first, second, third and fourth central openings are dimensionally configured to permit free axial movement of said depressor to engage said moveable plug.
