DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] For further illustrating the invention, experiments detailing a childproof perfume bottle are described below. It should be noted that the following examples are intended to describe and not to limit the invention.

[0026] A perfume bottle comprises a bottle body 1 and a bottle cap 2 covering the bottle body 1. The bottle body 1 comprises an upper connection part 11 comprising an external wall 12 comprising a male screw 13. The bottle cap 2 comprises an internal wall 21 comprising a female screw 23 matching the male screw 13 of the external wall 12. The external wall 12 of the upper connection part comprises a bulge, and a stop piece 15 is disposed at one end of the bulge 14. The internal wall 21 of the bottle cap 2 comprises a clamping block 24 which is capable of tightly fitting the bulge 14 of the external wall 12 after revolving the bottle cap to a certain angle. When the bottle cap 2 is screwed up and is connected to the upper connection part 11 of the bottle body 1, the clamping block 24 of the internal wall of the bottle cap 2 tightly fits the bulge 14 of the external wall of the bottle body. The clamping between the clamping block 24 and the bulge 14 is so tight that a child has no enough strength to detach the clamping block 24 from the bulge 14. Thus, the child cannot remove the bottle cap 2 from the bottle body 1. Only an adult who has enough strength can do so.

[0027] A transition slope is 16 disposed at another end of the bulge 14 to facilitate the clamping block 24 to slide to fit tightly the bulge 14. A clamping slope is 25 disposed at one end of the clamping block 24 to facilitate the clamping block 24 to slide to fit tightly the bulge 14.

[0028] The male screw 13 of the external wall 12 of the bottle body comprises a starting point 131 at a lower part of the external wall 12 and an end point 132 at an upper part of the external wall 12, and the bulge 14 and the stop piece 15 are disposed at front of the starting point 131 of the male screw. The female screw 23 of the internal wall 21 of the bottle cap comprises a starting point 231 at a lower part of the internal wall 21 and an end point 232 at an upper part of the internal wall 21, and the clamping block 24 is disposed at front of the starting point 231 of the female screw.

[0029] The male screw 13 of the external wall 12 of the bottle body and the female screw 23 of the internal wall 21 of the bottle cap are continuously convex or concave. Thus, the moving of the bottle cap on the bottle body is unidirectional.

[0030] The bottle body 1 and the bottle cap 2 are cylindrical, conical, or elliptic cylindrical. The bottle body 1 and the bottle cap 2 can be made of plastic, metal, glass and other materials by one-step injection molding.

[0031] The stop piece 15, the bulge 14, and the transition slope 16 are integrated, and the bottle body 1, the stop piece 15, the bulge 14, and the transition slope 16 are integrated by injection molding with plastic as raw materials.

[0032] The clamping block 24 and the clamping slope 25 are integrated, and the bottle cap 2, the clamping block 24, and the clamping slope 25 are integrated by injection molding with plastic as raw materials.

[0033] The diameter of the upper connection part 11 of the bottle body 1 is less than the diameter of the bottle body 1. The diameter of the upper connection part 11 of the bottle body 1 is slightly smaller than the diameter of the bottle cap 2 so that the bottle cap can cover the upper connection part 11 of the bottle body. The height of the upper connection part 11 of the bottle body is slightly smaller than that of the bottle cap.

[0034] An air vent 20 is disposed at a top surface of the bottle cap 2. The air vent 20 can be any through hole having any shapes. The number of the air vent 20 is one or more.

[0035] A sealing ring 17 is disposed at a lower part of the external wall 12 of the upper connection part of the bottle body, and the stop piece 15, the bulge 14, and the transition slope 16 are disposed above the sealing ring 17.

[0036] The stop piece 15, the bulge 14, and the transition slope 16 are tightly attached to the external wall 12 of the bottle body. The stop piece 15 is higher than the bulge 14. When the clamping block 24 slides along the transition slope 16 to lean against the stop piece 15, the front end of the clamping block 24 is impeded by the stop piece, whereby fixing the bottle cap 2.

[0037] The clamping block 24 is a curved strip protrusion tightly attached to the internal wall of the bottle cap. Optionally, the clamping block 24 is a convex block, a convex point, or a convex ring. The upper surfaces of the clamping block 24 and the clamping slope 25 are a convex arc in shape.

[0038] While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
