Insulated capsule for canned liquid

Abstract

A capsule for a can containing liquid includes a lower shell with first locking detent mechanism and first modular attachment threads, and an upper shell with second locking detent mechanism and second modular attachment threads. The second modular attachment threads are configured to engage the first modular attachment threads and the second locking detent mechanism is configured to interlock with the first locking detent mechanism only when the first modular attachment threads and the second modular attachment threads are fully engaged. The upper and the lower shell enclose the can when the first modular attachment threads and the second modular attachment threads are fully engaged. A shell gasket seals between the lower shell and the upper shell, a can gasket disposed within the upper shell seals between the upper shell and an upper surface of the enclosed can, a lid removably attaches to the upper shell, and a lid gasket seals between the lid and an upper surface of the enclosed can.

What is claimed is: 
     
         1 . A capsule for a can containing liquid, comprising:
 a lower shell with first locking detent mechanism and first modular attachment threads;   an upper shell with second locking detent mechanism and second modular attachment threads, the second modular attachment threads configured to engage the first modular attachment threads and the second locking detent mechanism configured to interlock with the first locking detent mechanism only when the first modular attachment threads and the second modular attachment threads are fully engaged;   the upper and the lower shell configured to enclose the can when the first modular attachment threads and the second modular attachment threads are fully engaged;   a shell gasket configured for sealing between the lower shell and the upper shell;   a can gasket disposed within the upper shell and configured for sealing between the upper shell and an upper surface of the enclosed can;   a lid configured for removable attachment to the upper shell; and   a lid gasket disposed within the lid and configured for sealing between the lid and an upper surface of the enclosed can.   
     
     
         2 . The capsule of  claim 1  wherein the lid comprises a lid screw, a latch screw, a snap latch, and a latch ring.
