Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: an anti-falling plastic bottleneck device comprises a bottleneck 1 and a bottle cap 2, wherein the bottleneck 1 and a bottle body 3 are in an integral structure, the bottle cap 2 is detachably matched with the bottleneck 1, a bearing step 4 of the integral structure with the bottleneck 1 is arranged on the bottleneck 1, an external tooth 5 of the integral structure with the bottleneck 1 is arranged on the upper portion of the bearing step 4, an inner groove 6 is processed on one side of the external tooth 5, an external thread 7 is processed on the upper portion of the bottleneck 1 above the external tooth 5, an internal thread 8 matched with the external thread 7 is processed on the inner wall of the bottle cap 2, the bottle cap 2 and the bottleneck 1 are in threaded fit through the internal thread 8 and the external thread 7, a plurality of anti-sliding ribs 9 are processed on the outer wall of the bottle cap 2, a protective sleeve 10 of the integral structure with the bottle cap 2 is processed below the bottle cap 2, and an internal tooth 11 matched with the external tooth 5 is processed on the inner wall of the protective sleeve 10, the bottle cap is characterized in that the outer teeth 5 are symmetrically arranged at two sides of the outer wall of the bottle mouth 1, the number of the outer teeth 5 on each side is three, the wall thickness of the protective sleeve 10 is smaller than that of the bottle cap 2, the thickness of the protective sleeve 10 after the thickest part of the inner teeth 11 is overlapped with that of the protective sleeve 10 is still smaller than that of the bottle cap 2, the inner teeth 11 are uniformly distributed on the inner wall of the protective sleeve 10, and one surface, without the inner grooves 6, of the outer teeth 5 is a smooth slope surface.
The working principle is as follows: when the anti-falling plastic bottleneck device is used, the bottle cap 2 and the bottleneck 1 are screwed through the matching of the external thread 7 and the internal thread 8, the anti-slip edge 9 on the bottle cap 2 plays an anti-slip role, the internal teeth 11 on the inner wall of the protective sleeve 10 do not protrude out of the inner wall of the bottle cap 2, so in the screwing process of the bottle cap 2, the internal teeth 11 cannot interfere with the bottleneck 1, along with the continuous screwing-in of the bottle cap 2, the bottle cap 2 is continuously close to the bearing step 4 until the protective sleeve 10 is matched with the external teeth 5 along with the screwing-down of the bottle cap 2, the internal teeth 11 on the inner wall of the protective sleeve 10 are meshed with the external teeth 5 on the bottleneck 1, because one side of the external teeth 5 is smooth and sloping, and the other side is provided with the internal groove 6, when the internal teeth 11 are screwed down along with the bottle cap 2, the internal teeth 11 can pass through the smooth and sloping surface of the external teeth 5, but when, therefore, the bottle cap 2 can only be screwed in and cannot be screwed out, the matching reliability of the bottle cap 2 and the bottle mouth 1 is guaranteed, when the bottle cap 2 needs to be taken down, a user needs to increase screwing force to enable the protective sleeve 11 to be deformed and damaged, the bottle cap 2 can be screwed out only when the internal teeth 11 and the external teeth 5 are not meshed, and the thickness of the protective sleeve 10 is smaller than that of the bottle cap 2, so that the screwing force required by the protective sleeve 10 to be damaged is reduced, and a consumer can conveniently unscrew the bottle cap 2 by damaging the protective sleeve 10.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
