Bottle

Abstract

The invention relates to a bottle. A bottle cap comprises a lower cap and an upper cap which are connected through threads, an antitheft device is arranged between the lower cap and the upper cap, and a convex ring and convex teeth are arranged on the outer peripheral wall of a bottle neck; the lower cap comprises a lower cap bottle neck and a fixing cap, the fixing cap comprises an inner cap and an outer cap, through holes are formed in the lower cap bottle neck and the inner cap, and an inverted fastener and fixing strips are arranged on the inner peripheral wall of the outer cap; an inner plug is arranged at the internal top part of the upper cap; the antitheft device consists of an antitheft point on the lower cap and a containing chamber on the upper cap for containing the antitheft point. Compared with the prior art, the bottle has the advantages that the fixation in the longitudinal direction is realized by fastening the inverted fastener below the convex ring, the fixation in the transverse direction is realized by clamping the convex teeth between the two fixing strips, the lower cap is effectively fixed on the bottle neck and the opening of the upper cap is facilitated; since a silica gel sleeve on the inner cap is in interference fit with the internal part of the bottle mouth, the upper cap is in thread connection with the lower cap and the inner plug is fit in the through hole, liquid in the bottle is effectively prevented from leaking.

Description

technical field [0001] The invention relates to the technical field of bottles, in particular to a bottle that is easy to open, has good sealing performance, and has anti-theft and anti-leakage functions. Background technique [0002] Anti-theft bottle caps in the prior art are generally composed of an anti-theft ring fitted on the neck of the bottle and a bottle cap fitted on the mouth of the bottle. The bottle cap and the anti-theft ring are connected by an anti-theft point. The anti-theft point breaks, which plays a warning role whether the bottle cap has been opened, and plays a certain role in guaranteeing the quality and safety of the product; however, we often see such a phenomenon, we also rotate the bottle cap. It will make the anti-theft ring rotate together. At this time, the anti-theft point is difficult to break, or it is difficult to open the bottle cap, or the bottle cap and the anti-theft ring are screwed out together. This is not only inconvenient but also h...

Problems solved by technology

[0002] Anti-theft bottle caps in the prior art are generally composed of an anti-theft ring fitted on the neck of the bottle and a bottle cap fitted on the mouth of the bottle. The bottle cap and the anti-theft ring are connected by an anti-theft point. The anti-theft point breaks, which plays a warning role whether the bottle cap has been opened, and plays a certain role in guaranteeing the quality and safety of the product; however, we often see such a phenomenon, we also rotate the bottle cap. It will make the anti-theft ring rotate together. At this time, the anti-theft point is difficult to break, or it is difficult to open the bottle cap, or the bottle cap and the anti-theft ring are screwed out together. This is not only inconvenient but also has no anti-theft effect. The anti-theft ring and the bottle neck are not well fixed. If the anti-theft ring is firmly fixed on the bottleneck, the anti-theft ring will not rotate with the rotation of the bottle cap, and the anti-theft point will be easier to break

[0003] For the anti-theft caps mentioned above, we often see that the liquid in the bottle will still leak out even if the cap is put on the opened bottle. This is usually caused by the loose fit between the cap and the bottle mouth. Yes, in the prior art, in order to avoid the occurrence of this phenomenon, the bottle cap is generally provided with a foam sealing gasket that matches the bottle mouth. Although this plays a sealing role to a certain extent, this foam The sealing gasket is very easy to deform. After opening and closing the bottle cap many times, a gap will soon be formed between the foam sealing gasket and the bottle mouth, which will cause the liquid in the bottle to leak easily, which is also very easy to cause the inside of the bottle to leak. liquid expired
