Dispensing Vessel and Method of Use

Abstract

Disclosed is a disposable assembly for retaining and dispensing a powder into a bottle. The disposable assembly includes a vessel having a flared volume for retaining a powder with a neck having a slanted opening. A shear cap is affixed to the outside of the vessel neck and includes a hinged lid or flap at the shear cap distal end that covers the slated neck opening and a ledge at the shear cap proximal end for resting atop a bottle opening. A rib is located between said hinged lid and ledge having an outer diameter larger than the bottle opening. The cap rib mates with a like rib located about the mid-section of the vessel neck. The cap rib is squeezed by the bottle opening, which likewise squeezes the vessel neck rib, for shearing open the hinged lid with consequent release of powder retained in the flared vessel.

I claim: 
     
         1 . A disposable assembly for retaining and dispensing a product into a bottle, which comprises:
 (a) a vessel for retaining a product;   (b) a neck affixed to the vessel having a slanted opening and a rib about its mid-section; and   (c) a shear cap affixed to the outside of the vessel neck and comprising:
 (1) a hinged lid at the shear cap distal end that covers the slated vessel neck opening; 
 (2) a ledge at the shear cap proximal end for resting atop a bottle opening; and 
 (3) a rib located between said hinged lid and said ledge having an outer diameter larger than the bottle opening, said ledge being squeezed by the bottle opening, which likewise squeezes the vessel neck rib, for shearing open the hinged lid with consequent release of product retained in said vessel. 
   
     
     
         2 . The disposable assembly of  claim 1  made from a plastic. 
     
     
         3 . The disposable assembly of  claim 1 , wherein said vessel has a flared volume. 
     
     
         4 . The disposable assembly of  claim 1 , wherein said product is a liquid or a particulate. 
     
     
         5 . A method for dispensing a product retained with a disposable assembly, which comprises the steps of:
 (1) providing said disposable assembly comprising:
 (a) a vessel for retaining a product; 
 (b) a neck affixed to the vessel having a slanted opening and having a rib about its mid-section; and 
 (c) a shear cap affixed to the outside of the vessel neck and comprising:
 (1) a hinged lid at the shear cap distal end that covers the slated vessel neck opening; 
 (2) a ledge at the shear cap proximal end for resting atop a bottle opening; and 
 (3) a rib located between said hinged lid and said ledge having an outer diameter larger than the bottle opening, said ledge being squeezed by the bottle opening, which likewise squeezes the vessel neck rib, for shearing open the hinged lid with consequent release of product retained in said vessel; and 
 
   (2) inserting the vessel neck into an open bottle for dispensing the powder therefrom.   
     
     
         6 . The method of  claim 3 , wherein said dispensing assembly is made from a plastic. 
     
     
         7 . The method of  claim 5 , wherein said vessel has a flared volume. 
     
     
         8 . The method of  claim 6 , wherein said product is a liquid or a particulate. 
     
     
         9 . A disposable assembly for retaining and dispensing a powder into a bottle, which comprises:
 (a) a vessel having a flared volume for retaining a powder;   (b) a neck affixed to the flared volume having a slanted opening and having a rib about its mid-section; and   (c) a shear cap affixed to the outside of the vessel neck and comprising:
 (1) a hinged lid at the shear cap distal end that covers the slated vessel neck opening; 
 (2) a ledge at the shear cap proximal end for resting atop a bottle opening; and 
 (3) a rib located between said hinged lid and said ledge having an outer diameter larger than the bottle opening, said ledge being squeezed by the bottle opening, which likewise squeezes the vessel neck rib, for shearing open the hinged lid with consequent release of powder retained in said flared volume. 
   
     
     
         10 . The disposable assembly of  claim 9  made from a plastic.
