Description

Plastic bottle cap structure that can prevent the anti-theft ring from breaking off in advance

The present invention relates to the technical field of plastic bottle caps, in particular to a plastic bottle cap structure that can prevent the anti-theft ring from breaking off in advance.

Due to the development of medicine, a variety of drugs are used very frequently. In addition to the efficacy of the drug itself, the shape of the drug can also be divided into liquid, granular, powder, etc., and various drugs must have compatible bottles to ensure that The airtightness of the drug does not affect its original chemical properties; and there is a liquid medicine bottle that can hold the liquid medicine, most of which are suitable for eye drops and other external medicines. There is a container for the medicinal liquid, and the function of the cap on the bottle body is to seal and prevent leakage. liquid.

The applicant of this case recently filed the design patent No. D190486 of the Republic of China. Its appearance is characterized by the lower part of the bottom ring sleeve, and the indirect and straight type that provides the sleeve to lock the outermost part of the anti-theft tooth of the top part of the screw tooth of the medicine bottle is connected downward. Anti-theft ring; thereby providing an intact judgment of tearing when the cap is unscrewed.

However, in fact, when the cap sleeve is locked on the medicine bottle, it is easy to cause the product defect problem of tearing of the anti-theft teeth due to the excessive force of the mechanical sleeve lock.

The main purpose of the present invention is to provide a plastic bottle cap structure that can prevent the anti-theft ring from breaking off in advance, and between the bottle cap and the anti-theft ring are provided with bumps that can be locked in and abutted against each other. When the bottle cap sleeve is locked at the level of the medicine When the bottle cap is used, the convex point is used to prevent the bottle cap from rotating excessively, so as to prevent the anti-theft teeth from breaking away in advance.

The structure of the present invention includes: a bottle cap which is composed of a female cap and an anti-theft ring, the female cap is used to lock the bottle mouth of a bottle body; the anti-theft ring is arranged on the lower end of the female cap, and passes through the A pair of anti-theft teeth arranged at equal distances connect the female cap to the anti-theft ring, and the anti-theft ring is broken by rotating the female cap counterclockwise, and whether the bottle body is opened can be judged by whether the anti-theft teeth are broken or not; it is characterized in that ;

The lower end of the female cover is provided with a first protruding point extending toward the anti-theft ring, the anti-theft ring is provided with two protruding points extending toward the female cover, and the first protruding point and the second protruding point are on the female cover When rotated clockwise, they are locked into each other to stop each other, and the bottle cap is prevented from over-rotating by the first convex point and the second convex point, thereby preventing the anti-theft teeth from breaking away in advance.

Through the above description, the features and effects of the present invention are briefly described as follows: the present invention adds a first convex point and a second convex point that can be inserted into each other on the original bottle cap structure, when the packaging machine locks the bottle cap sleeve on the bottle When the bottle cap is installed, the first and second bumps are locked into each other to stop each other. The first bump and the second bump are used to avoid excessive rotation of the bottle cap, thereby preventing the anti-theft teeth from breaking away in advance, thereby improving the Product yield.

As shown in FIG. 2 to FIG. 5 , the plastic bottle cap structure of the present invention can avoid the early disconnection of the anti-theft ring, and can be applied to various types of plastic bottles at present, such as eye drop cans, medicine cans and related products. The bottle cap embodiment is an eyedrop bottle cap for illustration, but in actual application, if the bottle body is a medicine bottle, the bottle cap is the bottle cap and other embodiments, which are not limited to this application.

As shown in FIG. 5 , the structure of the plastic bottle cap of the present invention that can prevent the anti-theft ring from being disengaged in advance is composed of a bottle cap 10 including a female cap 1 and an anti-theft ring 2 , and the female cap 1 is used to set the lock. At the mouth of a bottle body 3; as shown in Figure 2, the anti-theft ring 2 is arranged at the lower end of the female cap 1, and the female cap 1 is connected with the anti-theft ring 2 through several anti-theft teeth 4 arranged at equal distances , by rotating the mother cap 1 counterclockwise to break the anti-theft ring 2, and through whether the anti-theft teeth 4 are broken, it can be judged whether the bottle body is intact or has been opened.

As shown in Figures 3 and 4, the lower end of the female cover 1 is provided with a first convex point 5 extending in the direction of the anti-theft ring 2, and the anti-theft ring 2 is provided with two convex points 6 extending in the direction of the female cover 1, And the first bump 5 and the second bump 6 are locked into each other when the female cap 1 rotates clockwise, and the bottle cap 10 is prevented from over-rotating by the first bump 5 and the second bump 6 . In this way, the situation that the anti-theft tooth 4 breaks away in advance is avoided.

It can be known from the above-mentioned structural features that the present invention adds a first bump 5 and a second bump 6 that can be snapped into each other on the original bottle cap 10 structure. When the packaging machine locks the bottle cap 10 on the bottle body 3 When the bottle cap 10 is over-rotated, the first bump 5 and the second bump 6 are locked into each other to stop each other, and the bottle cap 10 is prevented from being over-rotated by the first bump 5 and the second bump 6, thereby preventing the anti-theft tooth 4 from breaking away in advance. situation, thereby improving product yield.

To sum up, the structure of the present invention has never been seen in various books or publically used, and it sincerely meets the requirements of the invention patent application.

It needs to be stated that the above are the specific embodiments of the present invention and the technical principles used. If the changes are made according to the concept of the present invention, the functions produced by it still do not exceed the spirit covered by the description and drawings. , shall be within the scope of the present invention, and shall be stated together.
