Abstract A disassembleable valve is disclosed wherein a hollow glass insert having a circular sealing surface on one end for sealing the passage therethrough is positioned within a tubular plastic member, and a precision spherical ball of a diameter to establish a seal at the insert sealing surface is captured for forming the seal. A liquid dispensing device is provided with a disassembleable valve and includes a cap structure adapted to be secured onto the top of a liquid container and provided with integral tubular sleeve forming a tubular portion of the valve and with a syringe mounted on the cap for moving fluid through the valve. The syringe has a ring on the outside surface of the barrel and a shroud connected to the syringe piston movable within limits set by the ring. The cap has inserts for different shaped fluid containers and a stabilizing stand.
A disassemblable valve compRising, in combination a tubular plastic member having a uniformly cylindrical inside wall surface for a length, a hollow, cylindrical, glass insert slidably inserted into said tubular member with the outside surface of said insert in tight frictional engagement with said length of the inside wall surface of said plastic member for normally holding the glass insert and the plastic member together, said insert having a precision circular sealing surface on one end thereof for sealing the passage through said insert; a precision spherical ball of diameter to establish a seal at said insert sealing surface when positioned thereon; and a ball capture and closure member sealingly engaging said tubular member and positioned at the end of said insert having said sealing surface.
