Abstract

A compartmentalized container for storing, mixing and dispensing a plurality of incompatible liquids which must be segregated prior to use, which container includes in combination; an outer and an inner cylindrical side wall components, a bottom plug and a closure cap means with a sealing member. Each of said outer and inner side wall components has an open bottom end and is, when combined, concentrical with respect to the other, and the both of said open ends being substantially in a plane to be stopped with the bottom plug in common. Said outer side wall component has a mouth at its top with a fastening screw and said inner side wall component has a closed top end with a fastening screw extending therearound, the threading-in direction of which screw is in reverse to that of the first-mentioned screw. Said closure cap means has a fastening screw engageable with that of the mouth of the outer side wall component and another fastening screw engageable with that of the closed top end of the inner side wall component.

Claims

1. A compartmentalized container for storing, mixiNg and dispensing liquids which must be segregated prior to use, which comprises in combination;

an outer and an inner cylindrical side wall components each having an open bottom end disposed concentrically with respect to the other such that both of said open bottom ends are substantially in a plane, said outer side wall component having a mouth at its top with a fastening screw and said inner side wall component having a closed top end with a fastening screw extending therearound, the threading-in direction of which screw being in reverse to that of the first-mentioned screw, a bottom plug stopping said open bottom ends in common, a closure cap means having a fastening means engageable with the fastening screw of said mouth of the outer side wall component and another fastening means engageable with the fastening screw of said closed top end of the inner side wall component, and an annular sealing member being placed between the closure cap means and the mouth of the outer cylindrical side wall component.

2. A compartmentalized container as claimed in claim 1, wherein the fastening screw of the mouth of the outer cylindrical side wall component extends around the exterior thereof and engages with an interior fastening means of the closure cap.

3. A compartmentalized container as claimed in claim 1, wherein the fastening screw of the mouth of the outer cylindrical side wall component extends around the interior thereof and engages with an exterior fastening means of the closure cap.

4. A compartmentalized container as claimed in claim 1, wherein said bottom plug has an outer circular kilt being fitted the open bottom end of the outer cylindrical side wall component and an inner circular kilt being fitted the open bottom end of the inner cylindrical side wall component.

5. A compartmentalized container as claimed in claim 4, wherein ridges or fillets are provided around the inner circular kilt which ridges or fillets can easily be pressed to deform and serve for the sealing against the interior of the bottom end when the latter is stopped with th kilt by forced insertion

6. A compartmentalized container as claimed in claim 1, wherein the bottom plug is welded around the periphery of the open bottom end of the outer cylindrical component.
