Aluminum Foil-Sealing Hygiene Bottle Cap

Abstract

This patent design is involved in leakage-proof sealing design for a plastic bottle cap, which works with water dispenser. Technique issue: It focuses on designs of an interior water outlet lid at leakage-proof and on design of a pliably wedged sealing ring in the cap. The patent design aims at eradicating phenomena that an interior water outlet lid drops in water to create secondary pollution and rescinding use of a leakage-proof foaming gasket in the cap. Embodiment: 1. Employ a kind of non-toxic, odorless, and food grade aluminum foil lid to seal the interior water outlet in a cap. 2. Add a fixed pliably wedged ring onto interior sidewall of a cap to replace a mobile polyethylene foaming gasket. Effects: The patent cap design possesses simple structure, hygiene, and strong sealability. It can eradicate leak from plastic interior lid, rescind foaming gasket use, reduce cost and avoid secondary pollution to bottled water.

The embodiment of this invention in which an exclusively claimed property or privilege is defined as follows: 
     
         1 . An aluminum foil-sealing hygiene bottle cap and its interior water outlet lid are adopted by a piece of food-grade aluminum foil. 
     
     
         2 . A bottle cap as defined in  claim 1 , in which the top area of its interior water outlet is divided into two different surface areas:
 a smaller glossy area that occupies about one-fifth (⅕) of the top area in the water outlet; and   a larger tiny teeth area that occupies about four-fifth (⅘) of the top area in the water outlet.   
     
     
         3 a. A bottle cap as defined in  claim 1 , in which the interior sidewall design of a cap, extra added a fixed pliably wedged ring to rescind any other foaming annular gaskets. 
     
     
         3 b. A bottle cap as defined in  claim 1  and claim  3 a, the fixed pliably wedged ring composes an included angle with the interior sidewall of a cap where the wedge-angled ring possesses a leakage-proof dam function.
