Description of the Invention: [Technical Field] The present invention relates to a rotary expansion stopper, and more particularly to a stopper suitable for a liquid-filled bottle, a container such as a sputum, and the like The opening of the altar, the altar, etc. is completely sealed and easy to open. [Prior Art] As in the United States, No. 2, 718, 974 J'JU Qing took the muscles to find the pro-independence. The outer cup-shaped expansion body was built with several solid pieces, and the several solid pieces were joined and expanded by the outer cup. The inner edge of the body is fastened, and the plurality of solid pieces form an inner diameter of the central cone, and the inner diameter of each solid piece has an inner thread, and the cone plug is used to screw the inner diameter of the cone with the outer thread. The inner thread is rotated outwardly by the rotation of the cone plug, and the outer cup-shaped expansion body is tightly extended toward the edge and the bottle mouth is in close contact with each other. According to the "expanded stopper" patent, the plurality of solid pieces disclosed are separated from each other to form a non-joining relationship. Therefore, when the solid piece is expanded outward by the rotation of the cone-cone plug, the solid The sheet can only be made into a phase-shaped ship to the outer cup-shaped expansion body. Thus, when the body expands to the outer periphery, the shape becomes a non-circular polygonal shape, so that the sealing property between the outer body and the bottle mouth is insufficient. Moreover, since the IU of the expanded stopper is finely divided (4) and (4), after the stopper is closed for a long time in the opening of the container, the solid sheet is also shaped: ^ fatigued so that (10) _ woven (four) filament becomes... SUMMARY OF THE INVENTION The object of the present invention is to improve the above disadvantages, and to provide a rotary expansion stopper which can be applied to a stopper for a container for filling a liquid, a jar, a crucible, etc., and the bottle can be used. The opening is completely sealed and easy to open. A second object of the present invention is to provide a rotary expansion stopper which can be expanded to form an outer circumference of a perfect circular shape for sealing the opening of the bottle, the cymbal, the cymbal or the like into a comprehensive seal. The rotary expansion stopper of the present invention is mainly made up of an expandable body made of a deformable material. The expansion body is provided with an open chamber, and the chamber is provided with a non-circular cone wall to accommodate a cone element. The cross-section of the cone element coincides with the formation of the tapered wall of the expansion body, the cone element has a central screw hole; a positioning ring, a through hole is combined with the expansion body, and a peripheral flange of the positioning ring is provided with a flange; An outer cover is provided with a central wall and a vertical wall at the periphery of the edge. The central column has an external threaded portion that is screwed with a central screw hole of the cone member, and the vertical wall is engaged with the flange of the positioning ring. The rotation of the outer cover drives the cone member to move axially and causes the expansion body to expand toward the outer periphery or to undergo an inward contraction reset due to its own elasticity. [Embodiment] The above and other objects, features, and advantages of the present invention will become more fully understood. And in conjunction with the drawings, a detailed description will be given below. According to a preferred embodiment of the present invention, the present invention is mainly composed of an expanded body, a cone element 2, a branch ring 3 and an outer cover 4, and the expanded body 1 is made of rubber. Or made of a deformable material such as foam to make the 1331116

When the cone element 42 is sleeved to move the outer wall 1 and the peripheral wall can be moved to the tapered end, the expansion can open the opening of the container 5 to make the expansion Body 1 piece 2 is turned toward the end of the turn 14: sealed; otherwise 'when the cone element can be elastic to form the direction of the 曰;; shift == the expansion body! The outer peripheral wall is easily taken out by the opening of the bowl 5. Is the vertical expansion so that the expansion body 1 of the present invention can rotate the positioning ring 3 by the outer cover 4, so that the outer peripheral wall of the expansion body 1 can be expanded to the outer periphery to expand the expansion The body 1 can form a tight seal of the H 5 , or the outer peripheral wall of the expandable body 1 can be formed into an inward contraction reset by its own elasticity so that the expandable body 1 can be easily taken out by the opening of the container 5. In addition, the rotary expansion yarn of the present invention, due to the body, therefore, the cone 2 forces the outer wall of the expansion body to expand, and can be visibly integrated into a comprehensive ship and used for a long time. The miscellaneous component 2 does not have any problem of fatigue, and the rotary expansion stopper of the present invention can have better sealing properties. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and any of the various changes and modifications of the above-described embodiments are still within the spirit and scope of the present invention.
