Abstract

A closure for containers particularly adapted for use in dispensing liquid beverages. The closure includes a spout for delivery of the liquid beverage, and the spout is provided with a flow control valve housed within the spout. The valve and spout are formed of resilient materials, and the valve is normally closed, but is openable by lip pressure applied externally of the spout.

Claims

1. A valved spout for use in dispensing a liquid from a container, said spout comprising outer and inner resilient members, said outer member defining the exterior of said spout and having inlet and outlet ends with its inlet end toward the container, said inner member having an open end positioned inside said outlet end of the outer member and a valved end presented in the same direction as the inlet end of the outer member, said valved end of the inner member having opposed planar portions defining a closed valve apex which opens upon application of edgewise lateral compression to said opposed planar positions.

2. A container closure for selectively dispensing a liquid, said closure comprising:

a lid portion for closing an open container and generally defining the top plane of the container, a valved spout integral with and extending from the lid portion above the top plane, said spout comprising;

outer and inner resilient portions nested one within the other;

the outer portion is generally tubular and defines the exterior of the spout, said outer portion has inlet and outlet ends with the inlet end presented toward the container; and

the inner portion has an open end presented in the same orientation as said outlet end and a valved end with opposed terminal portions defining a normally closed valve apex yieldingly openable by application of lateral compression in a direction edgewise to said opposed terminal portions.

3. A controllable valve device for use in dispensing a liquid from a container, said device comprising two resilient components nested one within the other;

an outer tubular component which is open at both ends and has its first end presented toward the container and an inner component having an open outlet end and a valved end, said outlet end presented in the same direction as the second end of the outer component with the outer wall of said outlet end in circumferential engagement with the inner wall of the outer component and said valved end defining a normally closed valve yieldingly openable by application of lateral compression through the wall of the outer component.
