Referring to Fig. 1 and Fig. 2, a container mouth sealing structure bottle cap includes a button cap 1, a cap body 2, a septum 3, a liquid outlet 4 and a return port 5.

The buckle cover 1 can be fastened on the cover body 2, and the fastening method can be screw connection or buckle connection. The buckle cover 1 and the cover body 2 can be arranged independently, or can be connected together, and a connecting piece 101 integrally formed with the outer wall of the two is provided for connection.

The cover 2 has an annular cover wall 201 . The wall thickness of the annular cover body is 1mm-4mm, and the height is 5mm-45mm. The wall of the ring-shaped cover body is in the shape of an inverted taper, and the range of the inverted taper is between 0.1°-3°. The design of the annular shape of the inverted taper is conducive to the smooth release of the product during injection molding, shortening the injection cycle and prolonging the service life of the mold.

Preferably, the inner side of the annular cover wall 201 is provided with an annular cover inner buckle 202 . The inner buckle 202 of the annular cover bites the outer wall of the mouth of the container, so that the cover 2 and the container are closely matched without loosening. The inner buckle height range of the annular cover is between 0.2 mm and 1.3 mm protruding from the inner side of the annular cover wall, and the width is between 1 mm and 5 mm.

The spacer 3 is located in the ring-shaped cover wall 201 and is sealingly connected with the ring-shaped cover wall 201 . The separator 3 is provided with a liquid outlet 4 and an exhaust port 5 . The separator 3 is sequentially provided with a first-level annular funnel groove, a second-level funnel groove, a third-level one-way funnel groove, a fourth-level funnel groove and a fifth-level funnel groove from top to bottom.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , an annular adhesive reducing groove 310 is provided below the joint between the periphery of the spacer 3 and the annular cover wall 201 . The annular glue reducing groove 310 can solve the problems such as shrinkage, deformation, long cycle of product shrinkage, deformation, long cycle and loose sealing after being installed on the container mouth after the overall increase of the cover body after the thickening of the wall thickness. The groove width of the annular glue reducing groove 320 is 0.2mm-2mm, and the groove depth is 0.2mm-3mm.

The bottom surface of the annular glue reducing groove 310 is the spacer 3 , the groove arm on one side is the annular cover wall 201 , and the opposite groove wall is an annular sealing gasket 320 . The annular sealing gasket 320 enables the top of the container mouth to be sealed against leakage. As an embodiment of the present utility model, the annular sealing gasket 320 adopts a separately assembled structure, and the size of the annular sealing gasket is flexibly selected according to the type of container and the actual sealing requirements, so as to adapt to the container opening in different seasons and different Regions, different material container sealing needs.

After the design of the annular adhesive reducing groove 310 in the structure of the cover body 2, the thickness of the cover body 2 is reduced, resulting in insufficient strength. For this reason, a plurality of said bone positions 330 are provided to play the role of support and reinforcement. This not only solves the problems of product shrinkage, deformation, and long cycle time during injection molding production, but also supports and strengthens the plastic cover, and solves the problems of loose sealing and leakage after being installed on the container mouth. The width of the bone position is 0.2mm-3mm.

An annular sealing column 340 is arranged below the spacer 3, the annular sealing column 340 is located on one side of the annular sealing gasket 320 and is concentric and connected with the annular sealing gasket 320, and the annular sealing column 340 surrounds the annular sealing gasket 320. Describe the liquid outlet 4 and the exhaust port 5 and other structures and form a certain distance with these structures, and its range is between 0.3mm-10mm. The annular sealing column 340 enables the inner wall of the container mouth to be sealed without leakage. The annular sealing column 340 can be assembled separately or integrated with the septum 3 by injection molding, which is selected according to the actual sealing requirements of the container type. The thickness of the annular sealing column is 0.2mm-3mm, and the height of the annular sealing column is 2mm-10mm.

Preferably, the annular sealing post 340 is inserted into the inner wall of the container mouth, and the shape of the insertion end 341 is set as a tapered chamfered shape, so as to facilitate insertion into the inner wall of the container mouth.

Preferably, one or more circular arc-shaped small bosses 343 are provided on the contact surface 342 of the annular sealing post 340 inserted into the container and the inner wall of the container. When the inner wall of the container mouth shrinks and deforms, the small boss 343 can be in closer contact with the inner wall of the container mouth to enhance the sealing effect. The height of the small boss 343 is 0.05mm-1mm, and the width is 0.2mm-5mm.
