ABSTRACT:
A premeasured dispensing bottle cap consists of an inner sleeve and an outer sleeve. The inner sleeve is adapted for engaging the neck of a bottle. The walls of the inner sleeve define a measuring chamber which holds a premeasured volume of liquid. The outer sleeve has a dispensing outlet with a hinged lid. The inner sleeve and the outer sleeve have ports for the flow of fluid from the bottle to the inner sleeve, and from the inner sleeve to the outer sleeve and the dispensing outlet with the bottle in an inverted position. The flow is such that with the outer sleeve in a fill position, liquid flows from the bottle to fill the measuring chamber in the inner sleeve, but not into the outer sleeve, and with the outer sleeve in a dispensing position, liquid flows from the measuring chamber through the outer sleeve and dispensing outlet, but not from the bottle to the inner sleeve.
In some embodiments the flow of liquid is controlled by a valve moved by sliding the outer sleeve along the longitudinal axis of the inner sleeve, and in other embodiments through the alignment of partitions in the inner and outer sleeves by rotating the outer sleeve about the longitudinal axis of the inner sleeve.
