Description

Technical Field

[0001] The utility model relates to a sealing piece used on a bottle, in particular to an integrated anti-drop bottle cap. Background Art

[0002] Bottle caps are a crucial component of bottles, tightly sealing the bottle opening to prevent contaminants such as dust and bacteria from entering the bottle, thereby ensuring product hygiene and quality. Currently, bottle caps on the market are connected to the anti-theft ring via a tear stud. After the bottle cap is installed on the bottle, the anti-theft ring snaps onto the flange of the bottle opening, while the bottle cap is screwed onto the bottle opening. To open the bottle, the bottle cap is twisted, breaking the tear stud between the cap and the anti-theft ring. The bottle cap can be removed from the bottle opening, while the anti-theft ring remains. Bottles with these caps are easily lost, making it difficult to reseal the bottle later. If the cap falls off, it cannot be recycled along with the bottle and can also pollute the environment. Utility Model Content

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] like Figures 1 to 5As shown, the integrated anti-drop bottle cap described in the present invention includes: a cover body 1 made of plastic material, an internal thread 11 is provided on the inner wall of the cover body 1, and a thickening layer 12 is provided on the inner side wall of the cover body 1 below the internal thread 11, which protrudes inward. The thickening layer 12 and the inner side wall of the cover body 1 are smoothly connected by an S-shaped curved surface 13, and an upper arc-shaped notch line 2 is provided on the thickening layer 12. When the cover body 1 is folded through the arc-shaped notch line 2, it will be torn upward and irregular tear marks will appear. In order to solve this problem, I-shaped notch lines 21 are extended upward at both ends of the upper arc-shaped notch line 2, and a rounded corner is provided between the upper arc-shaped notch line 2 and the I-shaped notch line 21 to improve the connection between the upper arc-shaped notch line 2 and the I-shaped notch line 21. The tear film 22 is provided in the I-shaped notch line 21, and the tear film 22 can stabilize the I-shaped notch line 2. The inner and outer side walls of the tear film 22 gradually narrow and fit together from top to bottom. The thin bottom and thick top structure of the tear film 22 can be easily torn. Seven upper tearing columns 23 are arranged at intervals in the upper arc notch line 2. The upper tearing columns 23 are semi-cylindrical. The semi-cylindrical upper tearing columns 23 are easily torn after being subjected to tension. An avoidance notch 121 is provided on the inner wall of the thickened layer 12. The avoidance notch 121 is located between the two ends of the upper arc notch line 2. A bending groove 3 is provided on the inner wall of the cover body 1 located at the avoidance notch 121. The bending groove 3 includes: two horizontal groove sections 31, two arc groove sections 32 and a transition groove section 33. The lower side walls of the flat groove section 31, the arcuate groove section 32 and the transition groove section 33 are all inclined side walls arranged downward and inward, which is convenient for demoulding during injection molding and can improve the structural stability of the bending groove 3. The two horizontal groove sections 31 are located on the left and right sides of the transition groove section 33 and are connected to the transition groove section 33. The two ends of the two horizontal groove sections 31 are respectively close to the two I-shaped notch lines 21. The two horizontal groove sections 31 and the transition groove section 33 can act as hinges to facilitate the opening of the cover body 1. The two arcuate groove sections 32 are located on the left and right sides of the transition groove section 33 and are connected to the transition groove section 33. The arcuate groove section 32 is located below the horizontal groove section 31 on the same side. The end of the arcuate groove section 32 is flush with the end of the horizontal groove section 31 on the same side. 1. The bending groove 3 formed by connecting two arc-shaped groove sections 32 and a transition groove section 33 is similar to an X shape. When the two horizontal groove sections 31 act as hinges, the two arc-shaped groove sections 32 can make the bending groove 3 fit on the bottle mouth for bending, reducing deformation or damage caused by uneven force during the folding process. Moreover, after the X-shaped bending groove 3 is provided on each bottle cap, it can be ensured that the folding of each bottle cap is consistent, which helps to improve the consistency and reliability of the final product. A lower arc notch line 4 with the same height as the upper arc notch line 2 is provided on the cover body 1 below the bending groove 3, and a semi-cylindrical lower tearing column 41 is provided at the center of the lower arc notch line 4. A lower tearing column 41 can not only ensure the stability of the lower arc notch line 4,The lid 1 can also break quickly when subjected to an upward pull when opened. Several inverted teeth 42 are evenly distributed around the inner wall of the lid 1 below the lower arc-shaped notch line 4. Anti-slip grooves 5 are protruding from the outer wall of the lid 1 above the upper arc-shaped notch line 2. There are no anti-slip grooves 5 on the outer wall of the lid 1 between the two ends of the upper arc-shaped notch line 2. This prevents the bending groove 3 from being affected, ensuring that the bending groove effectively bends the lid 1.

[0021] When the integrated anti-drop bottle cap of the present invention is fixed on the bottle, the inverted teeth 42 on the cover body 1 are snapped on the flange of the bottle mouth, and the internal thread 11 on the cover body 1 is threadedly connected with the external thread of the bottle mouth. At this time, the upper tearing column 23 in the upper arc notch line 2, the lower tearing column 41 in the lower arc notch line 4 and the tearing membrane 22 are all kept intact. When the bottle cap needs to be opened, the bottle cap is twisted, and the bottle cap gradually moves upward along with the thread, and the inverted teeth 42 are stuck on the bottle mouth to hinder the overall upward movement of the bottle cap. During the rotation and pulling process, the upper tearing column 23 in the upper arc notch line 2 and the lower tearing column 41 in the lower arc notch line 4 are torn off, and the bottle cap located above the upper arc notch line 2 will pull the upper arc notch line 2 and the lower arc notch line 4 upward to open it when it moves upward. The bottle cap is staggered with the lower arc notch line 4. When the two are pulled upward together to open, the bottle cap above the upper arc notch line 2 can remain horizontal and be screwed, preventing the internal thread 11 on the bottle cap from getting stuck with the external thread of the bottle mouth. The bending groove 3 also moves upward with the bottle cap. When the internal thread 11 in the bottle cap is disengaged from the external thread of the bottle mouth, the bottle cap is folded toward the bending groove 3. During the bending process, the bottle cap will tear the tear film 22 in the I-shaped notch line 21, thereby allowing the bottle cap to be opened smoothly. After being opened, the bottle cap can maintain an opening of 150° to 160° under the cross support of the bending groove 3. When the user drinks the liquid in the bottle directly with his mouth, the opened bottle cap will not touch the user's mouth. When pouring the liquid in the bottle, the bottle cap will not hinder the flow of liquid. When the bottle cap needs to be closed, it only needs to be bent back onto the bottle mouth and then tightened.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
