Abstract:
1. A device for storing and dispensing a substance comprising: a container comprising a body defining therein a variable-volume storage chamber for receiving and storing the substance, a pierceable wall located in fluid communication with the storage chamber, and a first connecting portion for connecting another component thereto; and a one-way valve assembly comprising: a valve body including a body base; at least one piercing portion engageable with the pierceable wall, wherein at least one of the piercing portion and the pierceable wall is movable relative to the other of the piercing portion and the pierceable wall between a first position wherein the piercing portion is not piercing the pierceable wall, and a second position wherein the piercing portion is piercing the pierceable wall and the storage chamber is in fluid communication with the one-way valve assembly for allowing a flow of substance from the storage chamber therethrough; a second connecting portion that is connectable to the first connecting portion of the container for fixedly securing the valve assembly to the container; a valve seat and at least one flow aperture extending through the valve body adjacent to the valve seat and in fluid communication with the storage chamber in the second position for receiving the substance therefrom; and a valve cover including a cover base mounted on the body base and fixedly secured against axial movement relative thereto; and a valve portion overlying the valve seat, wherein the valve portion defines a predetermined radial thickness and a diameter less than a diameter of the valve seat to thereby form an interference fit therebetween.
