Abstract

A bottle cap type additive container connectable to a mineral water bottle to improve flavor is disclosed to include a cylindrical container body threadable onto the threaded neck of a bottle, a water soluble good grade additive contained in the container body, a filter cloth-based insert inserted into the bottom open side of the container body to keep the additive inside the container body, and a seal film sealed to the bottom open side of the container body.

1 . A bottle cap type additive container comprising:
 a cylindrical container body, said cylindrical container body having an inside chamber, a water soluble food grade additive filled in said inside chamber, and an inner thread spirally extending along an inside wall near a bottom open side thereof for threading onto the threaded neck of a bottle;   an insert inserted into the bottom open side of said cylindrical container body to seal said water soluble food grade additive inside said cylindrical container body, said insert having an annular base and a filter element mounted within said annular base for allowing passing of a fluid in and out of said inside chamber of said cylindrical container body and filtering the fluid passing therethrough.   
   
   
       2 . The bottle cap type additive container as claimed in  claim 1 , further comprising a sealing film sealed to the bottom open side of said cylindrical container body. 
   
   
       3 . The bottle cap type additive container as claimed in  claim 1 , wherein said cylindrical container body has an inside annular flange adapted to stop said insert in place. 
   
   
       4 . The bottle cap type additive container as claimed in  claim 1 , wherein said insert has a pointed tip extended from a bottom side of said annular base. 
   
   
       5 . The bottle cap type additive container as claimed in  claim 1 , wherein said filter element is a filter cloth. 
   
   
       6 . The bottle cap type additive container, wherein said filter element is a filter paper. 
   
   
       7 . The bottle cap type additive container as claimed in  claim 1 , wherein said food grade additive is a flavor additive. 
   
   
       8 . The bottle cap type additive container, wherein said food grade additive is a Chinese medicine additive. 
   
   
       9 . The bottle cap type additive container as claimed in  claim 1 , wherein said food grade additive is a nutrient substance. 
   
   
       10 . The bottle cap type additive container as claimed in  claim 1 , wherein said food grade additive is carbonates.
