Cap

Abstract

A cap having a first part with a piercing element and a second part has a chamber with a bottom seal. The chamber is configured to receive the piercing element. The piercing element pierces the bottom seal upon a rotation of the first and second parts with respect to each other.

What is claimed is: 
     
         1 . A cap comprising:
 a first part comprising a piercing element;   a second part comprising a chamber with a bottom seal, said chamber configured to receive said piercing element, wherein said piercing element pierces said bottom seal upon a rotation of said first and second parts with respect to each other.   
     
     
         2 . The cap of  claim 1 , wherein said piercing element comprises a tapered or angled bottom. 
     
     
         3 . The cap of  claim 1 , wherein said bottom seal is tapered or angled. 
     
     
         4 . The cap of  claim 1 , wherein said piercing element and said bottom seal have a matching taper or angle. 
     
     
         5 . The cap of  claim 1 , wherein said first part comprises a top piece and said second part comprises a bottom piece. 
     
     
         6 . The cap of  claim 1 , further comprising a save lock arranged to restrict rotation of said first and second part with respect to each other. 
     
     
         7 . The cap of  claim 6 , wherein said save lock feature comprises teeth. 
     
     
         8 . The cap of  claim 1 , further comprising a structural element configured to limit free rotation of the first part with respect to the second part after unlocking of a save lock feature. 
     
     
         9 . The cap of  claim 1 , wherein said piercing element is arranged to pierce only a portion of said bottom seal. 
     
     
         10 . The cap of  claim 1 , wherein said bottom seal further comprises an area of weakness for piercing. 
     
     
         11 . The cap of  claim 1 , wherein said second part further comprises a save lock feature arranged to restrict rotation of said second part with respect to an attached container. 
     
     
         12 . A cap comprising:
 a first hollow part capped at one end thereof;   a second hollow part having a punchable seal closing one end thereof and slidably receiving the first hollow part therein with the punchable seal axially opposite from the capped end to define an enclosed reservoir therebetween;   a save lock holding the two hollow parts rotationally fixed with respect to each other, wherein unlocking the save lock allows the first hollow part to rotate with respect to the second hollow part such that the uncapped end of the first hollow part at least partially dislodges the punchable seal.   
     
     
         13 . The cap of  claim 12 , wherein said uncapped end of the first hollow part and said punchable seal have a similar taper or angle. 
     
     
         14 . The cap of  claim 12 , wherein said save lock feature comprises breakable teeth. 
     
     
         15 . The cap of  claim 12  further comprising an annular part disposed around and securely attached to the outside of the second hollow part, the annular part formed with threads extending around its inner diameter to threadably engage a container and dispose the punchable seal within the container upon a rotation of the first hollow part with respect to the second hollow part. 
     
     
         16 . The cap of  claim 15 , further comprising a second save lock holding the second hollow part and container rotationally fixed with respect to each other, wherein unlocking the save lock allows the second hollow part to rotate with respect to the container. 
     
     
         17 . The cap of  claim 12 , wherein said punchable seal further comprises a line of weakness for puncturing. 
     
     
         18 . The cap of  claim 12 , further comprising a structural element configured to limit free rotation of the first hollow part with respect to the second hollow part after unlocking of said save lock feature. 
     
     
         19 . A method for forming a cap comprising:
 forming a first hollow part capped at one end thereof with a first protrusion and a first recess on its outer diameter;   forming a second hollow part having a punchable seal closing one end thereof and capable of slidably receiving the first hollow part therein with the punchable seal axially opposite from the capped end to define an enclosed reservoir therebetween;   forming a second protrusion around the inner diameter of the second hollow part; forming a second recess to receive the first protrusion therein; forming a first annular space between the two hollow parts;   sealing said first annular space by engagement of the second protrusion with the first recess;   forming a breakable annular seal disposed to hold the two hollow parts in a rotationally fixed relationship;   allowing the first hollow part to be rotated with respect to the second hollow part for the first protrusion to be received in the second recess and the uncapped end of the first annular part to dislodge the punchable seal by rotating;   forming an annular part disposed around and securely attached to the outside of the second hollow part to define a second annular space therebetween;   forming threads extending around the inner diameter of the third annular part to engage a bottleneck in the second annular space and dispose the punchable within the bottle upon a rotation of the first hollow part with respect to the second hollow part.
