Sealing structure for bottle

Abstract

A sealing structure includes a bottle and a cap sealing the opening of the bottle. The bottle includes a body, an opening formed on the body and a flange protruding from periphery of the opening. The flange has a curved shape having a lower end depressed and connected to periphery of the body to form a neck portion. The cap includes a skirt portion which surrounds the periphery of the body and has a plurality of teeth equally spaced on periphery of the skirt portion and extending longitudinally along the body and a plurality of radial protrusions protruding toward the periphery of the body between every two adjacent teeth. The teeth are pressed by a machine in a lower position thereon so that the radial protrusions abut periphery of the neck portion, and the cap abuts the flange and is conformal with and completely fitted to the flange.

1 . A sealing structure, comprising:
 a bottle comprising a body, an opening formed on the body and a flange protruding from a periphery of the opening, wherein the flange has a curved shape having a a depressed arc portion located on a lower end thereof and connected to a periphery of the body to form a neck portion; and   a cap movable to a sealed position and sealing the opening of the bottle and comprising a top, a skirt portion connected to the top and surrounding the periphery of the body of the bottle and a plurality of teeth equally spaced on a periphery of the skirt portion and extending longitudinally along the body of the bottle and a plurality of radial protrusions protruding inwardly toward the periphery of the body of the bottle and being located between every two adjacent teeth of the plurality of teeth, wherein, when the plurality of the teeth are pressed by a sealing machine in a lower position thereon, the cap is moved to the sealing position, the radial protrusions having a shape and size corresponding with and abutting a periphery of the neck portion formed by the depressed arc portion of the bottle, and an inner periphery of the cap having a shape and size corresponding with and abutting a periphery of the flange;   wherein, when the cap is located in the sealing position, the interior periphery of the cap, the plurality of radial protrusions, and the skirt portion of the cap have a shape corresponding with and continuously abutting the bottle from an upper portion of the flange of the bottle to a portion of the bottle located below the neck portion formed by the depressed arc portion of the bottle.
