Bottle cap with a chamber for raw material and pressure gas

Abstract

A bottle cap provided with a fixed portion and a movable portion which are separably screwed with each other. The fixed portion is for supporting the movable portion and has an attaching portion to an opening of a bottle and a through hole on an axial line. The movable portion has an inner plug portion which protrudes from a face thereof on the axial line and passes through the through hole. The inner plug portion is provided with a chamber for raw material and pressure gas. An opening plane at the other end of the chamber is sealed by a plug. The plug has a flange projects from the inner plug portion and is to be opened as a periphery portion of the through hole interferes the flange during relative movements of the fixed portion and the movable portion.

What is claimed is:  
     
         1 . A bottle cap ( 1 ) provided with a fixed portion ( 2 ) and a movable portion ( 3 ) which are separably screwed with each other; 
 said fixed portion ( 2 ) being for supporting said movable portion ( 3 ) and having an attaching portion ( 2   a ) to an opening ( 11   a ) of a bottle ( 11 ) and a through hole ( 2   b ) on an axial line (x),    said movable portion ( 3 ) having an inner plug portion ( 4 ) protruding from a face ( 3   a ) thereof on said axial line (x) and through said through hole ( 2   b ), said inner plug portion ( 4 ) being provided with a chamber ( 5 ) for raw material ( 12 ) and pressure gas ( 13 ), an opening plane ( 5   a ) at the other end of said chamber ( 5 ) being sealed with a plug ( 6 ), between said plug ( 6 ) and said fixed portion ( 2 ) there existing a plug opening means ( 7 ) and said plug ( 6 ) being to be opened by said plug opening means ( 7 ) during relative movements of said fixed portion ( 2 ) and said movable portion ( 3 ).    
     
     
         2 . A bottle cap as claimed in  claim 1  wherein of which material is either of PE (polyethylene) or PP (polypropylene).  
     
     
         3 . A bottle cap as claimed in  claim 1  wherein of which material is either of PET (polyethylen-telephtalate) or aluminum.  
     
     
         4 . A bottle cap as claimed in any one of  claims 1  to  3 , wherein said plug opening means ( 7 ) consists of a flange ( 6   a ) projecting from said inner plug portion ( 4 ) of said plug ( 6 ) and a periphery portion ( 2   c ) of said through hole ( 2   b ) which protrudes in the passage of said flange ( 6   a ).  
     
     
         5 . A bottle cap as claimed in  claim 4 , wherein said periphery portion ( 2   c ) comprises a pin member ( 2   d ) protruding in parallel with said axial line (x).  
     
     
         6 . A bottle cap as claimed in any one of  claims 1  to  3 , wherein said plug opening means ( 7 ) consists of said fixed portion ( 2 ), said plug ( 6 ) and a connecting member ( 2   e ) which connects said fixed portion ( 2 ) with said plug ( 6 ).  
     
     
         7 . A bottle cap as claimed in any one of  claims 1  to  3 , wherein said pressure gas ( 13 ) is inert gas.  
     
     
         8 . A bottle cap as claimed in  claim 7 , wherein said pressure gas ( 13 ) is one which is chosen among Nitrogen, Helium, Argon, CO 2 , NO or mixing gasses of two or more these gases.  
     
     
         9 . A bottle cap as claimed in any one of  claims 1  to  3 , wherein said raw material ( 12 ) is powder and one which is chosen among green tea, coffee, black tea, enriched mineral, an extracted mineral from the water in the depths of the sea, healthy food, medicine, an extracted fruit juice, dairy products, alcohol, an extracted vegetable juice, vitamins, sugar, herbs or ferment bacilli.  
     
     
         10 . A bottle cap as claimed in any one of  claims 1  to  3 , wherein said raw material ( 12 ) is solid and one which is chosen among green tea, coffee, black tea, enriched mineral, an extracted mineral from the water in the depths of the sea, healthy food, medicine, an extracted fruit juice, or dairy products.  
     
     
         11 . A bottle cap as claimed in any one of  claims 1  to  3 , wherein said raw material ( 12 ) is liquid and one which is chosen among green tea, coffee, black tea, enriched mineral, an extracted mineral from the water in the depths of the sea, healthy food, medicine, an extracted fruit juice, or dairy products.
