Detailed Description

An embodiment of the closure according to the present invention will be further described with reference to fig. 1 to 4.

The utility model provides a bottle lid, includes lid 1, be equipped with first internal thread 7 and second internal thread 5 on the inner wall of lid 1, the diameter of first internal thread 7 is greater than the diameter of second internal thread 5 and first internal thread 7 is located the opening part of lid 1, be equipped with transition screw thread 6 between first internal thread 7 and the second internal thread 5, first internal thread 7 and second internal thread 5 are connected respectively at transition screw thread 6's both ends, be equipped with the elasticity clamp 10 that has the external screw thread in the lid 1, elasticity clamp 10 and first internal thread 7, second internal thread 5 and transition screw thread 6 screw-thread fit, be equipped with the location structure with bottleneck 9 location on the elasticity clamp 10.

When in use, the positioning structure on the elastic clamp 10 is positioned and fixed with the bottle mouth 9 of the bottle, so that the elastic clamp 10 cannot move upwards and rotate relative to the bottle mouth 9, then the cover body 1 is rotated, as the elastic clamp 10 is in threaded fit with the first internal thread 7, the second internal thread 5 and the transitional thread 6, and the elastic clamp 10 cannot rotate, the cover body 1 can move downwards along the threads, as the diameter of the first internal thread 7 of the cover mouth is larger than that of the second internal thread 5, the elastic clamp 10 is gradually compressed when the cover body 1 moves downwards, and when passing through the transitional thread 6, the elastic clamp 10 can deform due to certain elasticity, and simultaneously is tightly matched with the second internal thread 5, and finally the two ends of the elastic clamp 10 are contacted and tightly hooped with the bottle mouth 9, meanwhile, the cover plate 4 on the bottle mouth 9 is abutted against the bottom surface in the cover body 1, so that the bottle mouth 9 is sealed, and when the bottle mouth 9 is to be opened, the elastic clamp 10 can be spread through self elastic force in a comfort mode, and the positioning structure can be detached from the bottle mouth 9, and the cover body is convenient to operate in a low-cost and easy and transport mode.

Example 1: as shown in fig. 1 and 2, the positioning structure is a key bar 2 arranged on the inner wall of the elastic clamp 10, the bottle mouth 9 is provided with a through groove matched with the key bar 2, the top of the key bar 2 is provided with a positioning protrusion 13, the bottom of the elastic clamp 10 is provided with a limiting ring 11 clamped with the bottom of the bottle mouth 9, the two key bars 2 in the embodiment are both positioned in the through groove, the limiting ring 11 at the bottom of the elastic clamp 10 is used for limiting the upward movement of the elastic clamp 10, the limiting protrusions are used for avoiding the downward axial movement of the cover body 1, the two key bars 2 are inserted in the through groove and respectively abut against the two side walls of the through groove, thus the rotation of the elastic clamp 10 can be limited, and meanwhile, when the elastic clamp 10 is held tightly, a certain expansion space is provided, and the connecting mode is suitable for most bottles with less earlier processing.

Example 2: as shown in fig. 4, the positioning structure is a key bar 2 arranged on the inner wall of the elastic clamp 10, the bottle mouth 9 is provided with a through groove matched with the key bar 2, the top of the elastic clamp 10 is abutted against the bottom of the bottle mouth 9, and the principle is the same as that of the embodiment 1, except that the top of the elastic clamp 10 is abutted against the bottom of the bottle mouth 9, so that the force born by the elastic clamp 10 is larger than that of the embodiment 1, and the elastic clamp 10 is not easy to deform.

In the invention, the positioning ring edge 8 is preferably arranged at the opening of the cover body 1, and the positioning ring edge 8 can position the elastic clamp 10 in the cover body 1 without rotating out by itself, so that the loss of the elastic clamp 10 is avoided.

Example 3: as shown in fig. 1, the middle part of the bottom surface in the cover body 1 is provided with a pressing protrusion 3, the middle part is provided with the pressing protrusion 3, the friction force is minimum when the cover body 1 is rotated, and meanwhile, the edge of the cover plate 4 on the bottle mouth 9 can automatically adjust the position when the cover plate 4 is pressed by the middle part, so that the cover plate 4 and the sealing ring are more pressed and attached.

Example 4: as shown in fig. 2, the bottom surface in the cover body 1 is provided with a compression ring 12, and the compression ring 12 can make the cover plate 4 on the bottle mouth 9 more uniformly stressed and not easily deformed, and the compression uniformity and the sealing performance are strong.

According to the invention, the two preferred key bars 2 are arranged at the two ends of the opening of the elastic clamp 10 respectively, when the cover body 1 rotates positively and negatively, stress points are arranged on the key bars 2, the positions of the key bars 2 determine the length of the force arms, and the key bars 2 are arranged at the two ends of the opening of the elastic clamp 10, so that the cover body 1 can work with the largest force arm when rotating positively and negatively, thereby saving labor and being more labor-saving and convenient when rotating the cover body 1.

The bottom of the elastic clamp 10 is preferably provided with a circle of clamping teeth 14, the side wall of the cover body 1 is provided with a pin hole, a plug pin 15 is arranged in the pin hole, one end of the plug pin 15 is arranged between the two clamping teeth 14, and when the elastic clamp 10 is completely screwed down, the plug pin 15 can be inserted between the two clamping teeth 14 to limit the rotation of the cover body 1.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
