Detailed Description
Referring to fig. 1 and 2, which show a specific structure of a preferred embodiment of the present invention, an easy-open bottle cap structure comprises an inner cap 10 and an outer cap 20, wherein the inner cap 10 is provided with a first thread 11, the outer cap 20 is provided with a second thread 21, and the inner cap 10 and the outer cap 20 are connected together by the first thread 11 and the second thread 21. According to the external force of screwing the cover at ordinary times, the manual cover screwing is replaced by the structural design, and the cover is automatically unscrewed, so that the problem that people such as children, girls and the old cannot cover due to insufficient strength is solved.
Wherein, the outer cover 20 is provided with a plurality of inclined holes 22 for installing springs 25 to provide power for opening the cover. The plurality of inclined holes 22 are spirally distributed along the outer cover 20, for example, the inclined angle between two adjacent inclined holes 22 is 30-180 degrees, preferably 45 degrees, with the center point of the outer cover 20 as the center. The outer cap 20 is provided with at least 3 rows of inclined holes 22 from bottom to top. The openings of the inclined holes 22 are formed in the inner wall surface 23 of the outer lid 20, and the bottoms of the inclined holes 22 are close to the outer wall surface 24 of the outer lid 20 but do not penetrate the outer wall surface 24. In this embodiment, the outer cover 20 is preferably a metal cover, and because the wall of the outer cover 20 is thin, the metal cover is still strong and is not easy to deform after the inclined hole 22 is formed.
A spring 25 and a pushing point 26 abutting against the spring 25 are installed in each inclined hole 22, so that the pushing point 26 can be telescopically contained in the inclined hole 22. Wherein, one end of the spring 25 is fixed at the bottom of the inclined hole 22, and the other end of the spring 25 is fixed with a pushing point 26. The pushing points 26 are in a block structure.
The inner cap 10 is a plastic cap or a wood cap, and in a normal state, the inner cap 10 is screwed into the outer cap 20 to compress each spring 25. The top of the inner cap 10 is provided with a locking cap 12, and the locking cap 12 may be integrally formed with the inner cap 10 or may be separately assembled. The locking cap 12 is provided with a locking point 13 connected to the outer cap 20. When the locking point 13 is in a locking state, the spring 25 compresses and stores elastic potential energy, and when the locking point 13 is in an unlocking state, the spring 25 stretches to push the inner cover 10 to be screwed out above the outer cover 20 through the pushing point 26, so that the cover is automatically opened. In this embodiment, at least two sets of springs 25 and a push point 26 are located below the inner cap 10, the push point 26 contacting the side of the inner cap 10 where it meets the bottom edge, thus providing the initial motive force for the cap 10 to unscrew upward.
In this embodiment, the locking cover 12 is provided with a first movable lock cylinder 14 and a second movable lock cylinder 15, the first movable lock cylinder 14 and the second movable lock cylinder 15 are symmetrically arranged, and an unlocking spring 16 is installed between the first movable lock cylinder 14 and the second movable lock cylinder 15; the locking points 13 are arranged at the tail ends of the first movable lock cylinder 14 and the second movable lock cylinder 15, and correspondingly buckled into locking holes 27 at the inner edge of the upper end of the outer cover 20. The tops of the first movable lock cylinder 14 and the second movable lock cylinder 15 are respectively provided with a labor-saving clamping piece 17. For example, the labor-saving clamping piece 17 can be an integral cartoon doll or a cartoon doll assembled on the first movable lock cylinder 14 and the second movable lock cylinder 15, and the design of the cartoon doll plays a role in decoration, particularly can absorb eyeballs of the child and plays a role in playing.
In use, the outer cap 20 is screwed into the inner cap 10, and the locking cap 12 at the upper end is locked with the outer cap 20 by the locking points 13 at both ends, so that the inner cap 10 cannot be ejected upward. When the cover is required to be opened, the labor-saving clamping piece 17 is pinched by the index finger and the thumb, so that the lock point 13 is separated from the outer cover 20, the inner cover 10 automatically rotates upwards to be opened under the action of spiral power generated by the name spring 25, and the whole process is not laborious, so that the aim of easily opening the cover is fulfilled.
The foregoing description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present invention are still within the scope of the technical solutions of the present invention.
