Bottle Cap Device

Abstract

A bottle cap device for a container includes a bottle cap, a subpackage vessel, a guiding structure, and a linkage structure. A retainer groove and a retainer member form a clutch structure, wherein the retainer groove and the retainer member are mated with each other and are disposed between said bottle cap and an outside surface of a top periphery of the subpackage vessel. A circular slotting tool is disposed within a containing cavity, wherein said circular slotting tool has a center hole and a cutting edge protruded on the bottom thereof. The guiding structure is disposed between said slotting tool and said subpackage vessel, wherein when the slotting tool is turned anticlockwise, the guiding structure limits the slotting tool to move downwards. The linkage structure includes a neck-shrinking helical block protruded downwardly from the bottom surface of the cover, and has a helical groove provided in a sidewall of a center hole of the slotting tool for mating with the helical block, wherein when the bottle cap is turned anticlockwise, the helical block pushes said helical groove to force the slotting tool to move under limitation of the guiding structure, and thus a cutting edge of the slotting tool opens a bottom separator of the subpackage vessel.

1 . A bottle cap device for a container, comprising:
 a bottle cap, which comprises a circular cover and a body extending downwardly from a periphery of said cover, wherein said body has an internal thread for fastening through clockwise;   a subpackage vessel, which comprises a separator sealedly enclosing a bottom thereof to form a containing cavity having a top opening, wherein a top periphery of said subpackage vessel passes through said body until a top end of said containing cavity connecting with said bottom surface of said cover correspondingly;   a retainer groove and a retainer member forming a clutch structure, wherein said retainer groove and said retainer member are mated with each other and are disposed between said bottle cap and an outside surface of a top periphery of said subpackage vessel, wherein when said bottle cap is turned clockwise, said retainer member is engaged with said retainer groove, and when said bottle cap is turned anticlockwise, said retainer member is forced to disengage from said retainer groove so as to disassemble said bottle cap from said subpackage vessel;   a circular slotting tool disposed within said containing cavity, wherein said circular slotting tool has a center hole and a cutting edge protruded on the bottom thereof;   a guiding structure disposed between said slotting tool and said subpackage vessel, wherein when said slotting tool is turned anticlockwise, said guiding structure limits said slotting tool to move downwards; and   a linkage structure, which comprises a neck-shrinking helical block protruded downwardly from said bottom surface of said cover, and has a helical groove provided in a sidewall of said center hole of said slotting tool for mating with said helical block, wherein when said bottle cap is turned anticlockwise, said helical block pushes said helical groove to force said slotting tool to move under limitation of said guiding structure, and thus said cutting edge of said slotting tool opens said separator of said subpackage vessel.   
     
     
         2 . The bottle cap device, as recited in  claim 1 , wherein said clutch structure comprises:
 a circular rail protrudently disposed on said outside surface of said top periphery of said subpackage vessel;   a plurality of fastening elements with inverted L shape symmetrically disposed on said circular rail;   a plurality of retainer groove respectively formed between said fastening element and said circular rail; and   a plurality of retainer member respectively caught with said retainer groove disposed on said bottle cap, wherein when said bottle cap is turned anticlockwise, said retainer member is forced to disengage from said retainer groove and then to apart from an open portion between said two retainer members, whereby said bottle cap is disassembled from said subpackage vessel.   
     
     
         3 . The assemblage of drink bottle and cap, as recited in  claim 1 , wherein said guiding structure has two section grooves symmetrically extended around said slotting tool, wherein said two section grooves have a left   shape and a right   shape respectively, wherein two resilient members are formed at said two section grooves respectively, wherein each of said resilient members has an free end slightly protruding from a periphery of said slotting tool, wherein said guiding structure further comprises a plurality of lengthways stops provided on a sidewall of said containing cavity to define a space therebetween to receive said slotting tool therein with each of said resilient members positioned between two said stops. 
     
     
         4 . The bottle cap device, as recited in  claim 1 , wherein said slotting tool further has a plurality of drain holes radially perforating said slotting tool. 
     
     
         5 . The bottle cap device, as recited in  claim 1 , wherein said internal thread of said body of said bottle cap is adapted for screwing up with an external thread provided at an outside surface of a bottle opening of the container. 
     
     
         6 . The bottle cap device, as recited in  claim 2 , wherein said internal thread of said body of said bottle cap is adapted for screwing up with an external thread provided at an outside surface of a bottle opening of the container. 
     
     
         7 . The bottle cap device, as recited in  claim 3 , wherein said internal thread of said body of said bottle cap is adapted for screwing up with an external thread provided at an outside surface of a bottle opening of the container. 
     
     
         8 . The bottle cap device, as recited in  claim 4 , wherein said internal thread of said body of said bottle cap is adapted for screwing up with an external thread provided at an outside surface of a bottle opening of the container. 
     
     
         9 . The bottle cap device, as recited in  claim 5 , further comprising a sealing structure, which comprises:
 a plurality of circular rings annularly provided on an outside surface of said subpackage vessel, wherein said circular rings are capable of tightly mating with said bottle opening;   a plurality of engaging teeth spacedly provided around said outside surface of said subpackage vessel and positioned above said circular ring; and   a plurality of engaging grooves provided around said bottle opening for engaging with said engaging teeth.   
     
     
         10 . The bottle cap device, as recited in  claim 6 , further comprising a sealing structure, which comprises:
 a plurality of circular rings annularly provided on an outside surface of said subpackage vessel, wherein said circular rings are capable of tightly mating with said bottle opening;   a plurality of engaging teeth spacedly provided around said outside surface of said subpackage vessel and positioned above said circular ring; and   a plurality of engaging grooves provided around said bottle opening for engaging with said engaging teeth.   
     
     
         11 . The bottle cap device, as recited in  claim 7 , further comprising a sealing structure, which comprises:
 a plurality of circular rings annularly provided on an outside surface of said subpackage vessel, wherein said circular rings are capable of tightly mating with said bottle opening;   a plurality of engaging teeth spacedly provided around said outside surface of said subpackage vessel and positioned above said circular ring; and   a plurality of engaging grooves provided around said bottle opening for engaging with said engaging teeth.   
     
     
         12 . The bottle cap device, as recited in  claim 8 , further comprising a sealing structure, which comprises:
 a plurality of circular rings annularly provided on an outside surface of said subpackage vessel, wherein said circular rings are capable of tightly mating with said bottle opening;   a plurality of engaging teeth spacedly provided around said outside surface of said subpackage vessel and positioned above said circular ring; and   a plurality of engaging grooves provided around said bottle opening for engaging with said engaging teeth.
