Inversion preventing structure and liquid bottle formed by same

Abstract

The invention discloses an inversion preventing structure and a liquid bottle formed by the same. The inversion preventing structure comprises a fixed piece, and a movable piece rotationally connected with the outer periphery of the fixed piece; multiple projections are arranged at the outer periphery of the inner end of the fixed piece; a guide inclined surface is arranged on one sides of the projections, and a vertical or barb-shaped butting surface is arranged at the other sides of the projections; ratchets matched with the projections are arranged on the inner side of the outer end of the movable piece; the movable piece rotates; the movable piece and the fixed piece are in tight threaded connection; when the movable piece is suffered from reverse rotating force, the butting surface stops the ratchets to form inversion preventing fixed connection of the movable piece and the fixed piece; and the movable piece is a plastic piece. Through inversion preventing fixed connection of the movable piece and the fixed piece, the liquid bottle is prevented from randomly opening, the contact of liquid in the bottle with external air is prevented, and the preferable protecting effect on the liquid in the bottle is achieved; and in addition, a bottle bottom is downwards recessed below the bottle body, and a spraying pump is provided for spraying out the liquid in the bottle as far as possible, so that the liquid residue is reduced, and the waste is prevented.

Description

technical field [0001] The invention relates to a bottle body, more specifically an anti-reversal structure and a liquid bottle made of it. Background technique [0002] At present, most of the spray bottles can be unscrewed between the neck and the bottle cap at will in order to facilitate opening, which will cause the liquid in the bottle to pour out, mix with external objects, oxidize and volatilize when exposed to air; in addition, the bottle of the spray bottle The bottom is flat, and it is impossible to spray out all the liquid in the bottle. If it contains precious liquid, it will cause waste. [0003] Therefore be necessary to design a kind of novel liquid bottle that can prevent inversion and can reduce liquid residue. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies of the prior art, and provide an anti-reverse structure and a liquid bottle made of it. [0005] In order to achieve the above object, the prese...
