1. Field of the Invention
The present invention relates generally to a safety bottle cap, and more particularly to an innovative one which is configured to prevent damage with an anti-burglary tearing flange.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
In order to prevent the possible personal injury arising from manually opening the bottle cap, a variety of currently available bottled products (e.g., beverage, mineral water and mouthwash) are generally fitted with anti-burglary safety bottle caps.
Such anti-burglary safety bottle caps are structured differently, but mainly designed in such a way to link the opening of the bottle cap with an anti-burglary tearing flange. Said anti-burglary tearing flange and the bottle cap are linked by spacing ribs. A snap stopper is often set at inner side of the anti-burglary tearing flange. When the bottle cap is screwed loose, the spacing ribs linked between the anti-burglary tearing flange and bottle cap will be torn, allowing to judge if the bottle cap is opened for anti-burglary identification.
However, the following shortcomings of conventional anti-burglary safety bottle cap are still found during actual applications:
Generally speaking, the caps of bottled products are not used as cups by the users due to very small volume, but if users drink mouthwash, it is possible to cause excessive drinking amount. In fact, only about 10 milliliters of mouthwash is required every time. Due to such features, the bottle cap of mouthwash product is perfectly suited for such requirement, so the bottle cap is extensively used to accommodate mouthwash. According to the structural design of the prior art, mouth injury may often occur if the users drink the mouthwash from the opening of the bottle cap. This is because spacing spurs (i.e.: residues at torn position of spacing ribs) are often generated at the opening of the bottle cap after the anti-burglary tearing flange and the bottle cap bottom are torn off. In such a case, the mouth of the users is vulnerable to the spurs of the bottle cap, especially in cold or dry regions.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.
Therefore, the inventor has provided the present invention of practicability after deliberate experimentation and evaluation based on years of experience in the production, development and design of related products.
The enhanced efficacy of the present invention is as follows:
Based on the unique structural configuration of the “safety bottle cap” of the present invention wherein a two-layer tear ring is sleeved between the lower section of the opening and the inner side of the aperture on the cover, when the cover is opened, the connecting ribs linked between the upper and lower rings are torn off, such that the upper and lower rings of two-layer tear ring are separated to ensure a smooth aperture. Hence, the safety bottle cap of the present invention features anti-burglary identification function and improved degree of protection against mouth injury.
The improvements brought about by this invention are as follow:
Based on the structural configuration wherein the top wall of said cover is provided with flange ring, the flange ring is abutted onto the inner side of the top of the opening to improve the leakage resistance effect.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
Said safety bottle cap includes an opening 10, formed on top section of a bottle 05 in a hollow tubing state. The exterior of the opening 10 comprises of an upper section 11 and a lower section 12, of which the upper section 11 is provided with a screwed portion 13.
A lower stop flange 14 is protruded on the lower section 12 of the opening 10.
An upper stop flange 15 is protruded on the lower section 12 of the opening 10 and also located at a spacing with the lower stop flange 14.
A cover 20 is defined into a hollow casing composed of a top wall 21, a side wall 22 and an aperture 23 at bottom of the side wall 22. The cover 20 is available with a tapered pattern (disclosed in
A hooking edge 24 is protruded on the inner side of the aperture 23 on the cover 20, and also located between the upper and lower stop flanges 14, 15.
A two-layer tear ring 30 is sleeved between the lower section 12 of the opening 10 and the inner side of the aperture 23 on the cover 20. The two-layer tear ring is composed of an upper ring 31, annularly sleeved onto a position correspondingly to the upper and lower stop flanges 15, 14. A lower ring 32 is annularly sleeved onto a position correspondingly to the lower stop flange 14. Multiple connecting ribs 33 are arranged at interval to link the upper ring 31 and lower ring 32. An outward flange 34 is protruded on exterior of the upper ring 31, and hooked upwards by the hooking edge 24. An upper abutting edge 35 is protruded on the inner side of the upper ring 31 and extended into the spacing of the upper and lower stop flanges 15, 14. A shift spacing X is reserved between the upper abutting edge 35 and upper stop flange 15, enabling the upper abutting edge 35 to shift along the shift spacing X. A lower abutting edge 36 is protruded on the inner side of the lower ring 32 and abutted upwards onto the lower stop flange 14.
Of which, the side wall 22 of the cover 20 is provided with a limit lug 25 at a spacing over the hooking edge 24, allowing to abut downwards onto the top of the upper ring 31 of the two-layer tear ring 30.
Of which, the top wall 21 of the cover 20 is provided with a flange ring 26, allowing it to abut onto the inner side of the top of the opening 10 to improve the leakage resistance effect.
Of which, the upper/lower stop flanges 15, 14 as well as the outward flange 34 and upper/lower abutting edges 35, 36 of the two-layer tear ring 30 are of either annular or spaced patterns.
Hence, the core feature of the safety bottle cap of the present invention lies in that, a two-layer tear ring 30 is sleeved between the lower section 12 of the opening 10 and the inner side of the aperture 23 on the cover 20. When the cover 20 is screwed loose, the lower abutting edge 36 on the lower ring 32 of the two-layer tear ring 30 is abutted upwards onto the lower stop flange 14 of the opening 10, such that the upper ring 31 of the two-layer tear ring 30 is driven by the cover 20 to shift upwards, and the connecting ribs 33 linked between the upper ring 31 and lower ring 32 are torn (disclosed in
