US 8,037,908 B1 · Slide valve for a bottle

Abstract

A slide valve system for a powder or liquid reservoir bottle which closes the reservoir bottle and allows the reservoir bottle to be tipped away from a subjacent dispensing bottle fed by the reservoir bottle. Once the reservoir bottle is tipped away the slide valve can be opened and the reservoir bottle filled. The reservoir bottle can then be closed by the slide valve and tipped back onto the dispensing bottle. Once on top of the dispensing bottle the valve can be opened and the contents of the reservoir bottle can enter the dispensing bottle by gravity flow. The slide valve must be closed in order to rotate the reservoir bottle away from the dispensing bottle. Likewise, the reservoir bottle must be locked in a vertical position with the reservoir bottle over the dispensing bottle in order to open the slide valve.

Dependent claims

A slide valve for a bottle, comprising:

a) a housing with a valve plate, said housing being attached to a rotatable reservoir bottle support plate;
b) said housing having a valve handle which opens and closes said valve plate over an opening in said slide valve;
c) said reservoir bottle support plate being rotatably attached to a dispensing bottle support plate so that said reservoir bottle support plate can be rotated towards an upper support plate;
and
d) a lock handle connected to an operating arm assembly, said operating arm assembly being attached rotatably to said reservoir support plate to lock said reservoir support plate to said upper support plate when said lock handle is moved to a locking position.
