Leak proof bottle lid

Abstract

A bottle with a lid mechanism to open and close both straw and air holes simultaneously. The preferred bottle features an external straw coupling which connects to both a mating internal straw coupling and an air hole coupling. Both the internal straw and air hole couplings preferably have spring-biased valves which simultaneously open to allow flow when the external straw coupling is connected to the bottle lid and simultaneously close to block flow when the external straw coupling is disconnected from the bottle lid. In this way, the bottle and bottle lid become leak proof when the external straw coupling is disconnected.

What is claimed is: 
     
         1 . A leak-proof bottle assembly comprising:
 a bottle;   a bottle lid with a straw hole and an air hole;   an external straw coupling;   an internal straw coupling inserted into said bottle lid; and, an air hole coupling inserted into said bottle lid;   wherein air and fluid can pass through said lid when said external straw coupling is connected to said internal straw and air hole couplings but air and fluid are blocked from passing through said lid when said external straw coupling is disconnected from said internal straw and air hole couplings.   
     
     
         2 . The leak-proof bottle assembly of  claim 1  wherein said internal straw and air hole couplings both have valves. 
     
     
         3 . The leak-proof bottle assembly of  claim 2  wherein said internal straw and air hole coupling valves are spring biased. 
     
     
         4 . The leak-proof bottle assembly of  claim 2  wherein said internal straw and air hole coupling valves both open simultaneously when said external straw coupling is connected to them and close simultaneously when said external straw coupling is detached from them. 
     
     
         5 . The leak-proof bottle assembly of  claim 1  wherein said external straw coupling is attached to a straw and a segmented tube. 
     
     
         6 . The leak-proof bottle assembly of  claim 1  wherein said air hole coupling includes a plunger, stop cone and spring. 
     
     
         7 . The leak-proof bottle assembly of  claim 6  wherein said stop cone is placed on top of said plunger and said spring rests below said plunger. 
     
     
         8 . The leak-proof bottle assembly of  claim 7  wherein portions of said plunger adjacent to said stop cone are polygonal in shape. 
     
     
         9 . The leak-proof bottle assembly of  claim 1  wherein said external straw coupling includes an MNPT nonvalved coupler. 
     
     
         10 . The leak-proof bottle assembly of  claim 9  wherein a cap is attached to said MNPT nonvalved coupler to open said air hole. 
     
     
         11 . The leak-proof bottle assembly of  claim 1  wherein said internal straw coupling includes a PMHB valved coupler. 
     
     
         12 . A leak-proof bottle assembly comprising:
 a bottle;   a bottle lid with a straw hole and an air hole;   an external straw coupling;   an internal straw coupling with a spring-biased valve inserted into said bottle lid; and, an air hole coupling with a spring-biased valve inserted into said bottle lid;   wherein said internal straw and air hole coupling valves open when said external straw coupling is connected to them and close when said external straw coupling is disconnected from them.   
     
     
         13 . The leak-proof bottle assembly of  claim 12  wherein said spring-biased valves each include a tip. 
     
     
         14 . The leak-proof bottle assembly of  claim 13  wherein said external straw coupling simultaneously presses down on the tips of the spring-biased internal straw and air hole coupling valves when the external straw coupling is connected to the internal straw and air hole couplings. 
     
     
         15 . The leak-proof bottle assembly of  claim 12  wherein said external straw coupling includes an MNPT nonvalved coupler. 
     
     
         16 . The leak-proof bottle assembly of  claim 12  wherein a cap is attached to said MNPT nonvalved coupler to open said air hole.
