Patent ID: 8590700

Claim:
A press-open storage device, comprising: a hollow container structure including a shell body ( 101 ) for storing contents ( 107 ) comprising particles, a powder, a slurry, a paste, a liquid, or dissolvable solid contents and arranged to be pushed into an opening portion of a selected container, wherein said hollow container body includes flanges for engagement with edges of an opening of the selected container when the hollow container body is inserted into said opening of the selected container, said shell body including a dispensing outlet at an axial bottom end of the shell body; a closure ( 102 ) arranged to fit into and close said dispensing opening of said shell body, said closure being attached to said shell body by a flexible structure ( 103 ); a force bearing structure ( 104 ) at an axial top end of the shell body and a pushing structure ( 106 ) extending from said force bearing structure, said force bearing structure comprising a flexible portion of said shell body arranged to move axially and cause said pushing structure ( 106 ) to engage said closure ( 102 ) when an external force is applied to the force bearing structure and thereby apply pressure to said closure ( 102 ) to cause said closure to open and thereby dispense said contents into said selected container, wherein said pushing structure is a separate body from said closure, does not engage said closure until said external force is applied to the force bearing structure to cause the force bearing structure to press said closure, and is disengaged from said closure after said closure has opened to dispense said contents into said selected container, wherein the flexible structure ( 103 ) is fixedly attached to or integrally formed with the shell body and pre-stressed in an opening direction of the closure such that when said closure is fitted into said dispensing opening to close the dispensing opening, closing of the dispensing opening is maintained against a pre-stressing force applied by the flexible structure, and such that when said external force is applied to said force bearing structure, said pre-stressing force facilitates opening of the dispensing opening to ensure dispensing of said contents; wherein said flexible portion of the force bearing structure is configured to engage a force applying member rotationally secured to said selected container for applying said external force to open said dispensing opening when said force applying member is turned relative to said selected container.
