Cap and ingredient for multi-compartment container

Abstract

A cap for a container includes a depressible structure arranged such that, when the depressible structure is depressed, the depressible structure applies force onto a first compartment, thereby rupturing the first compartment and dispensing a first ingredient into a second compartment of the container. The depressible structure can include a pliant material. Also described is a solid material shaped to concentrate force applied by the depressible structure at a first location of the first compartment to facilitate rupturing the first compartment. Additionally described is an ingredient that includes an effervescent material.

What is claimed is: 
     
         1 . A cap for a container, the cap comprising:
 a cap body structured to attach the cap to the container, the cap body comprising a first material;   a first compartment for a first ingredient; and   a depressible structure arranged such that, when the depressible structure is depressed, the depressible structure applies force onto the first compartment, thereby rupturing the first compartment and dispensing the first ingredient into a second compartment of the container, wherein the depressible structure comprises a second material more pliant than the first material.   
     
     
         2 . The cap of  claim 1 , wherein the first material comprises a hard plastic material and the second material comprises a soft plastic material. 
     
     
         3 . The cap of  claim 2 , wherein the hard plastic material comprises polypropylene, polyethylene, polyvinyl chloride or polyester. 
     
     
         4 . The cap of  claim 3 , wherein the soft plastic material comprises a vulcanizate or an elastomer of the hard plastic material. 
     
     
         5 . The cap of  claim 1 , wherein the depressible structure has a dome shape. 
     
     
         6 . The cap of  claim 1 , wherein the first compartment comprises a barrier to protect the first compartment from moisture, a gas and/or a gaseous compound. 
     
     
         7 . The cap of  claim 6 , wherein the barrier comprises a metal foil. 
     
     
         8 . The cap of  claim 7 , wherein the barrier comprises a plurality of metal foils that are sealed to form the first compartment. 
     
     
         9 . The cap of  claim 8 , wherein at least one of the plurality of metal foils is coated with a lacquer. 
     
     
         10 . The cap of  claim 1 , wherein the first compartment comprises a solid material and/or a powder having the first ingredient. 
     
     
         11 . The cap of  claim 9 , wherein the first ingredient is a dry ingredient that is sensitive to moisture. 
     
     
         12 . The cap of  claim 1 ,
 wherein the first material comprises a hard plastic material,   wherein the second material comprises a soft plastic material,   wherein the soft plastic material comprises a vulcanizate or an elastomer of the hard plastic material,   wherein the depressible structure has a dome shape,   wherein the first compartment comprises a barrier to protect the first compartment from moisture and/or oxygen,   wherein the barrier comprises at least one metal foil, and   wherein the first compartment comprises a solid material and/or a powder having the first ingredient.   
     
     
         13 . The cap of  claim 1 , wherein the first compartment comprises a solid material having the first ingredient, wherein the solid material is shaped to concentrate force applied by the depressible structure at a first location of the first compartment to facilitate rupturing the first compartment. 
     
     
         14 . The cap of  claim 1 , wherein the first compartment comprises the first ingredient, and wherein the first ingredient comprises an effervescent material. 
     
     
         15 . A cap for a container, the cap comprising:
 a cap body structured to attach the cap to the container;   a first compartment comprising a solid material; and   a depressible structure arranged such that, when the depressible structure is depressed, the depressible structure applies force onto the first compartment, thereby rupturing the first compartment and dispensing the solid material into a second compartment of the container,   wherein the solid material is shaped to concentrate force applied by the depressible structure at a first location of the first compartment to facilitate rupturing the first compartment.   
     
     
         16 . The cap of  claim 15 , wherein the solid material is shaped to concentrate force at a point. 
     
     
         17 . The cap of  claim 15 , wherein the solid material comprises a tablet with an angled, sharp edge. 
     
     
         18 . A cap for a container, the cap comprising:
 a cap body structured to attach the cap to the container;   a first compartment comprising a first ingredient; and   a depressible structure arranged such that, when the depressible structure is depressed, the depressible structure applies force onto the first compartment, thereby rupturing the first compartment and dispensing the first ingredient into a second compartment of the container,   wherein the first ingredient comprises an effervescent material.   
     
     
         19 . The cap of  claim 18 , wherein the effervescent material comprises calcium carbonate. 
     
     
         20 . The cap of  claim 18 , wherein the first compartment comprises a solid material having the first ingredient, the solid material being shaped to concentrate force at a first location of the first compartment to facilitate rupturing the first compartment.
