Built-in type anti-theft packaging bottle

Abstract

The invention provides a built-in type anti-theft packaging bottle. The built-in type anti-theft packaging bottle comprises a bottle body, a bottle cap, an anti-theft ring and a connecting rib, wherein threads are formed on the outer wall of the bottleneck of the bottle body and the inner wall of the bottle cap respectively; the inner wall on the lower side of the bottle cap is sunken outwards to form an accommodating cavity for accommodating the plastic anti-theft ring; the inside surface on the upper side of the bottle cap is superposed with the inner surface of the anti-theft ring; the anti-theft ring is connected with the inner wall of the bottle cap through the connecting rib; a plurality of clamping columns are formed on the inner wall of the anti-theft ring at intervals; first clamping grooves matched with the first clamping columns are formed in the corresponding positions of the outer wall of the bottleneck; the thickness of each first clamping column is gradually reduced in the clockwise direction of the inner surface of the anti-theft ring until the first clamping column is flush with the inner surface of the anti-theft ring; the thickness of each first clamping groove is gradually reduced in the clockwise direction of the outer surface of the anti-theft ring until the first clamping column is flush with the outer surface of the anti-theft ring; when the bottle cap is screwed tightly, the first clamping column can be clamped into and slide through the corresponding first clamping groove; and when the bottle cap is rotated reversely, the first clamping groove prevents the first clamping column clamped in the first clamping groove from rotating continuously.

Description

technical field [0001] The invention relates to an anti-theft packaging bottle, in particular to a built-in anti-theft packaging bottle with better anti-theft effect. Background technique [0002] At present, general packaging bottles, especially plastic packaging bottles, are equipped with anti-theft rings. When the bottle cap is tightened, the anti-theft ring and the bottle cap continue to form an integral body, and when the bottle cap is opened, the anti-theft ring will be separated from the bottle cap. In this way, it can be judged whether the packaging bottle has been opened after being packaged by whether the anti-theft ring is connected to the bottle cap, so as to achieve the effect of the anti-theft mark. The connection between the anti-theft ring and the bottle cap is traditionally connected by several connecting ribs, one end of the connecting rib is connected to the bottom of the bottle cap, and the other end is connected to the top of the anti-theft ring.

Problems solved by technology

The connection between the anti-theft ring and the bottle cap is traditionally connected by several connecting ribs, one end of the connecting rib is connected to the bottom of the bottle cap, and the other end is connected to the top of the anti-theft ring. One-piece injection molding, but this kind of external anti-theft packaging bottle is easy to fake or pry open, and because the anti-theft ring is made of plastic material, which has certain toughness, sometimes the anti-theft ring is not in contact with the bottle cap during the process of opening the bottle cap. The bottle cap is separated, the anti-theft ring and the bottle cap do not leave traces of opening, and can continue to be assembled, so that the real anti-theft effect cannot be achieved; in addition, because the anti-theft ring and the bottle cap are connected by connecting ribs, the connection point It is very fragile, and it is easy to break the connecting ribs during packaging, which will cause a certain amount of waste, and the design is not very user-friendly
