[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A wide-mouth bottle, such as Figure 1-Figure 5As shown, it includes a bottle body for containing liquid and a bottle cap 2 for sealing the bottle body, a bottle mouth 1 is fixedly connected to the upper end of the bottle body, the diameter of the bottle cap 2 is larger than the diameter of the bottle mouth 1, the outer wall of the bottle mouth 1 is threadedly connected with the inner wall of the bottle cap 2, a gasket 3 for improving the sealing performance of the wide-mouth bottle is clamped between the bottle mouth 1 and the inner wall of the bottle cap 2, the diameter of the gasket 3 is larger than or equal to the diameter of the bottle mouth 1, a clamping assembly is fixedly connected to the inner wall of the bottle cap 2, the clamping assembly cooperates with the gasket 3, when the bottle cap 2 and the bottle mouth 1 are tightened, the gasket 3 is squeezed between the bottle cap 2 and the bottle mouth 1, so that the bottle mouth 1 and the bottle cap 2 are sealed.

[0025] The diameter of gasket 3 is 107.2mm, and the diameter of bottle mouth 1 is 106.6mm. The diameter of gasket 3 is 0.6mm larger than that of bottle mouth 1. The size is accurate, so the positioning is accurate. Gasket 3 produces little damping when screwing on bottle cap 2, and bottle cap 2 opens smoothly, providing a good experience.

[0026] The gasket 3 is clamped and installed between the clamping assembly and the inside of the bottle cap 2 through the clamping assembly to prevent the gasket 3 from falling off the bottle cap 2 when the bottle cap 2 and the bottle mouth 1 are installed, affecting the installation sealing between the bottle mouth 1 and the bottle cap 2.

[0027] The snap-fit ​​assembly includes a protrusion 7, which is set to a rounded corner state to prevent damage to the gasket 3. The shape of the protrusion 7 is set to be annular, and the protrusion 7 is fixed to the inner wall of the bottle cap 2. The protrusion 7 is arranged around the inner wall of the bottle cap 2, and the protrusion 7 is snap-fitted with the gasket 3.

[0028] like Figure 2 and Figure 5 As shown, when the diameter of the gasket 3 is equal to the diameter of the outer wall of the bottle mouth 1, the gasket 3 tightly covers the bottle mouth 1, and the protrusion 7 clamps the gasket 3 in the bottle cap 2, or an aluminum foil gasket 3 with a diameter larger than the diameter of the bottle mouth 1 is used. When the bottle cap 2 and the bottle mouth 1 are installed, the protrusion 7 clamps the aluminum foil gasket 3 from top to bottom, and the edge of the aluminum foil gasket 3 fits the side wall of the bottle mouth 1.

[0029] An annular pattern 10 is fixedly connected to the top of the inner wall of the bottle cap 2. There are multiple groups of annular patterns 10, and the multiple groups of annular patterns 10 are equidistantly arranged. The multiple groups of annular patterns 10 are all located above the gasket 3, and the multiple groups of annular patterns 10 are all abutted against the gasket 3. The upper end of the gasket 3 is crimped with multiple layers. The innermost circle diameter of the annular pattern 10 is equal to the inner wall diameter of the bottle mouth 1, so as to prevent the annular pattern 10 from squeezing the gasket 3 located in the bottle mouth 1, causing the position of the gasket 3 in the bottle mouth 1 to be concave inward.

[0030] like Figure 5 As shown, the annular pattern 10 squeezes the gasket 3 so that the gasket 3 fits the bottle mouth 1 more closely. The end of the annular pattern 10 is rounded and will not damage the gasket 3 .

[0031] A groove 9 is provided at the upper end of the outer wall of the bottle mouth 1. The shape of the groove 9 is set to be annular. The groove 9 is snap-fitted with the protrusion 7. The groove 9 is located above the connection between the bottle cap 2 and the bottle mouth 1 and will not affect the sealing between the bottle mouth 1 and the bottle cap 2.

[0032] like Figure 5 As shown, the groove 9 facilitates the edge of the gasket 3 to be squeezed and deformed, or facilitates the edge of the gasket 3 to be squeezed and bent to fit the side wall of the bottle mouth 1.

[0033] The outer wall of the bottle mouth 1 is fixedly connected with an external thread 4, the inner wall of the bottle cap 2 is fixedly connected with an internal thread 6, the external thread 4 is threadedly connected with the internal thread 6, the external thread 4 is set to 1-2 turns, and the internal thread 6 is set to 1-2 turns.

[0034] like Figure 2-Figure 5 As shown, the external thread 4 and the internal thread 6 are threadedly connected to each other so that the bottle cap 2 and the bottle mouth 1 are sealed and installed.

[0035] The outer wall of the bottle mouth 1 is fixedly connected with a fixing ring 5 , which is sleeved on the outside of the bottle mouth 1 , and the outer wall of the bottle cap 2 is fixedly connected with an anti-slip pattern 8 .

[0036] like Figure 1 and Figure 5 As shown, the fixing ring 5 stabilizes the structure of the bottle mouth 1, and the anti-slip pattern 8 facilitates the screwing of the bottle cap 2.

[0037] The working principle of a wide-mouth bottle provided by the utility model is as follows:

[0038] The gasket 3 is clamped and installed between the protrusion 7 and the inside of the bottle cap 2 through the annular protrusion 7, so as to prevent the gasket 3 from falling off the bottle cap 2 and affecting the installation sealing between the bottle mouth 1 and the bottle cap 2 when the bottle cap 2 and the bottle mouth 1 are installed. When the bottle cap 2 and the bottle mouth 1 are tightened, the gasket 3 is squeezed between the bottle cap 2 and the bottle mouth 1 to make the bottle mouth 1 and the bottle cap 2 sealed. When the gasket 3 is squeezed between the bottle mouth 1 and the bottle cap 2, the gasket 3 is deformed to a certain extent, and the groove 9 makes the edge of the gasket 3 deform to fit the side wall of the bottle mouth 1, and the protrusion 7 applies force to squeeze the deformed edge of the gasket 3, thereby increasing the sealing effect of the gasket 3 between the bottle mouth 1 and the bottle cap 2.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
