Abstract:
A dispensing device affixed to the outside of a flexible container. A top part of the device includes a pump dome, a pump chamber ridge, and pump chamber flange. A bottom part includes a pump chamber, a pump chamber flange, a neck portion, and a dispensing head having an outlet at the end of a dispensing channel. The dispensing channel and the outlet are situated in a portion of the dispensing head that extends below the plane of the neck portion. The top part is sealed to the bottom part creating a channel between the pump chamber and the dispensing side of the dispenser. The device is sealed to the container in two discrete areas, namely the flange of the pump chamber and the bottom of the distal portion of the dispensing head. The area of the dispensing element between the pump chamber and the distal end of the dispensing head, referred herein as the neck portion, is not sealed to the container, causing the neck portion of the dispensing device to flex, pinching shut the channel that connects the pump chamber to the dispensing head.

Claim (Index 1):
A liquid dispensing device comprising:\n an elastomeric shape memory top part having a pump chamber dome, an annular pump chamber ridge around a periphery of said pump chamber dome, and a planar top part pump chamber flange around a periphery of said annular pump chamber ridge, a portion of the pump chamber flange extending away from a center of said pump chamber dome in a pump chamber flange extension; a rigid bottom part having a circular pump chamber portion and a dispensing head portion connected by a neck portion, said dispensing head portion defining a delivery port on a top side thereof proximate said neck portion, a fluid outlet at a distal end of said dispensing head portion, and a dispensing channel connecting said delivery port and said fluid outlet; wherein\n said pump chamber portion having an annular lower part pump chamber flange, said neck portion is an extension of said annular lower part pump chamber flange; and said annular lower part pump chamber flange and said neck portion are co-planar in an unstressed state, \n said top part connected to said bottom part along a periphery of said planar top part pump chamber flange and said pump chamber flange extension to define a channel between said pump chamber and said delivery port.
