Patent ID: 8708196

Claim:
A fluid delivery device comprising: a sleeve having a first end and a second end opposite the first end, the sleeve defining an opening at one of the first and second ends and a cavity between the first end and the second end, and wherein the sleeve is constructed from at least an outer wall and an inner wall that are arranged independently and separately from one another without a bond between the inner and outer walls, wherein the outer wall at least partially circumferentially surrounds the inner wall, and wherein the outer and inner walls are formed and arranged so as not to be separable from each other during use; a breakable container located within the cavity that contains a fluid to be delivered, wherein the container is selectively breakable upon application of a transverse squeezing force to the sleeve to disperse the fluid to be delivered within the cavity and to enable the fluid to be dispensed through the opening; wherein, when the transverse squeezing farce is applied to the sleeve, the transverse squeezing force is transferred first from the outer wall to the inner wall through an interface between the outer and inner walls, and then from the inner wall to the breakable container so as to break the container, and wherein the outer and inner walls and the interface between the outer and inner walls cooperate to inhibit penetration of the material of the breakable container through the sleeve after the breakable container has been broken by application of the transverse squeezing force.
