Embodiment Construction

[0031] Figure 1 and figure 2 It shows a specific embodiment of the closure for the container sealing structure according to the present invention. Fig. 1 is a front cross-sectional view showing a cap and a container sealed by the cap. figure 2 It shows the state of use of the cover, (a) is a front cross-sectional view of the state before the storage chamber is opened, and (b) is a front cross-sectional view of the state after the storage chamber is opened.

[0032] The cover 1 is used for the sealing structure of the container 2 and has a plug 4, a sealing plug 5 and a sleeve 6.

[0033] The plug 4 includes the following parts: a top plate 11, which seals the opening 3 of the container 2; a side wall 12, which protrudes from the top plate 11 along its axis X, and whose inner peripheral surface is threadedly connected with the outer peripheral surface of the opening; and a cylinder wall 15 at The inner side of the side wall 12 protrudes from the top plate 11 to form a receiving ca...

Abstract

A cap (1) has a plug portion (4), a seal plug (5) and a sleeve (6). The plug portion (4) has a top board (11) to cover an opening portion (3) of a vessel (2), a side wall (12) projecting from the top board along its axis (X) which wall has an inner circumferential surface fits on an outer circumferential surface of the opening portion (3), and a cylindrical wall (15) forming a receiving chamber (14) having an opening mouth (13) at its under end face which wall projects from the top board at inner side of the side wall (12). The seal plug (5) has outer diameter (D1) which is larger than outer diameter (D2) of the cylindrical wall (15) and an seals the opening mouth (13). The sleeve (6) is loosely fitted on the cylindrical wall (15) and opens the opening mouth (13) by separating the seal plug (5) from the cylindrical wall (15) at relative movement of the cap (1) to the vessel toward direction where they separate from each other. A sepal portion (16) on the outer circumference of the sleeve (6) has outer diameter larger than inner diameter (D3) of the opening portion (3) and has flexibility to passe the inner diameter (D3) bending so as to avoid backward moving.

Description

Technical field [0001] The present invention relates to a sealing structure of a container and a cover used for the sealing structure with a raw material containing cavity, which can mix the constituent raw materials of liquid composed of multiple raw materials, such as refreshing drinks, in a state that can be mixed during use. Separate and store in a container. Background technique [0002] Medicines used by mixing two medicines, as well as refreshing beverages that mix raw materials into liquids as products, etc., if they are not used or consumed for a long time after mixing, there may be reactions between the mixed medicines. Or the raw materials mixed in the liquid have deteriorated due to sunlight or oxygen in the air. Therefore, as a method of preserving the liquids used or consumed by mixing multiple raw materials while maintaining their original properties, a method has been proposed in which the sealing plug of the container containing the liquid is provided to contain ...
