Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle caps, in particular to an anti-drop opening and closing bottle cap. Background Art

[0002] Plastic caps are generally made of polyolefin as the main raw material and are formed through processes such as injection molding and hot pressing. Existing bottle caps mostly use detachable bottle caps, that is, the bottle cap is separated from the bottle body by rotating the bottle cap. During use, the bottle cap needs to be put away, otherwise it may cause the bottle cap to fall or be lost, making the bottle cap contaminated and unable to be used again. Utility Model Content

[0003] The utility model aims to solve the problem in the prior art that the bottle cap needs to be put away during use, otherwise the bottle cap may fall or be lost, causing the bottle cap to be contaminated and unable to be used again, and proposes an anti-falling opening and closing bottle cap.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses an anti-drop opening and closing bottle cap, comprising a bottle cap and a bottle body, wherein the bottle cap and the bottle body are adapted to each other, an inner thread is arranged on the inner side of the bottle cap, a sealing ring is arranged on the inner top of the bottle cap, a connecting bridge is fixedly connected to the outer bottom of the bottle cap, an anti-theft ring is fixedly connected to the other side of the connecting bridge, a plurality of twist-off teeth are fixedly connected to the bottom of the bottle cap and the top of the anti-theft ring, an upper limit groove is arranged on the inner side of the anti-theft ring, and the bottle cap and the anti-theft ring are connected as a whole through the connecting bridge to prevent the two from being separated.

[0006] As a preferred solution of the utility model, the outer side of the bottle body is respectively provided with an external thread, a lower limit ring and an upper limit ring, a fold is provided at the anti-theft ring near the connecting bridge, the anti-theft ring is located between the upper limit ring and the lower limit ring, and the upper limit ring is located between the external thread and the lower limit ring, and the upper limit ring and the lower limit ring restrict the anti-theft ring to be only between the upper limit ring and the lower limit ring, thereby preventing the bottle cap from falling off, and the internal thread, the external thread and the sealing ring cooperate with each other to prevent the liquid in the bottle from leaking.

[0007] As a preferred solution of the utility model, the height of the second buckle is lower than that of the first buckle, so that after the bottle cap is fully opened, the second buckle can completely clamp the first buckle, so that the bottle cap will not rebound.

[0008] Beneficial effects:

[0009] 1. The bottle cap and the anti-theft ring are connected as one through the connecting bridge to prevent the two from being separated. The bottle cap can be fully opened through the set fold. The first buckle and the second buckle cooperate to ensure that the bottle cap will not rebound due to the toughness of the connecting bridge after being fully opened.

[0010] 2. The upper limit ring and the lower limit ring limit the anti-theft ring to be only between the upper limit ring and the lower limit ring, thereby preventing the bottle cap from falling off. The internal thread, the external thread and the sealing ring cooperate with each other to prevent the liquid in the bottle from leaking.

[0011] In the utility model, the bottle cap, the internal thread, the sealing ring, the connecting bridge, the anti-theft ring, the bottle body, the external thread, the lower limit ring and the upper limit ring cooperate with each other, so that after the bottle cap is twisted open, the bottle cap will be restricted by the upper limit ring and the lower limit ring so that the bottle cap will not fall off, and after the bottle cap is tightened, the sealing ring and the bottle body are more closely contacted by tightening the internal thread and the external thread, so as to prevent the liquid in the bottle from leaking out.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1

[0022] Reference Figure 1-7A drop-proof opening and closing bottle cap comprises a bottle cap 1 and a bottle body 6, the bottle cap 1 and the bottle body 6 are adapted to each other, an inner thread 2 is arranged on the inner side of the bottle cap 1, a sealing ring 3 is arranged on the inner top of the bottle cap 1, a connecting bridge 4 is fixedly connected to the outer bottom of the bottle cap 1, an anti-theft ring 5 is fixedly connected to the other side of the connecting bridge 4, a plurality of twist-off teeth 10 are fixedly connected to the bottom of the bottle cap 1 and the top of the anti-theft ring 5, and the bottle cap 1 and the anti-theft ring 5 are connected as a whole through the connecting bridge 4 to prevent the two from being separated.

[0023] As a preferred solution of the utility model, the outer side of the bottle body 6 is respectively provided with an external thread 7, a lower limit ring 8 and an upper limit ring 9, a fold 11 is provided at the anti-theft ring 5 near the connecting bridge 4, the anti-theft ring 5 is located between the upper limit ring 9 and the lower limit ring 8, and the upper limit ring 9 is located between the external thread 7 and the lower limit ring 8. The upper limit ring 9 and the upper limit ring 8 limit the anti-theft ring 5 to be only between the upper limit ring 9 and the lower limit ring 8, thereby preventing the bottle cap 1 from falling off, and the internal thread 2, the external thread 7 and the sealing ring 3 cooperate with each other to prevent the liquid in the bottle body 6 from leaking.

[0024] It is a preferred solution of the utility model, the height of the second buckle 12 is lower than the height of the first buckle 13, so that after the bottle cap 1 is fully opened, the second buckle 12 can completely clamp the first buckle 13, so that the bottle cap 1 will not rebound.

[0025] Embodiment 2

[0026] The bottle cap 1, the connecting bridge 4 and the anti-theft ring 5 in the utility model can be integrally formed by a punching machine.

[0027] Working principle: The initial state is as follows Figure 4 As shown, the bottle cap 1 is rotated counterclockwise, and the bottle cap 1 rotates counterclockwise, so that the internal thread 2 and the external thread 7 are disengaged, and the twisting tooth 10 is broken, which serves to warn that the bottle of liquid has been opened. The bottle cap 1 is opened. Since the connecting bridge 4 connects the bottle cap 1 and the anti-theft ring 5, and the anti-theft ring 5 is restricted on the bottle body 6 by the upper limit ring 9 and the upper limit ring 8, the bottle cap 1 is also restricted on the bottle body 6 along with the anti-theft ring 5. After the bottle cap 1 is opened, the anti-theft ring 5 will be folded at the position of the fold 11. After the bottle cap 1 is fully opened, the second buckle 12 will clamp the first buckle 13, so that the bottle cap 1 will not rebound due to the toughness of the connecting bridge 4. The state after opening is as shown in FIG. Figure 1 As shown, after taking out or directly drinking the liquid in the bottle, cover the bottle cap 1 and rotate the bottle cap 1 clockwise so that the internal thread 2 and the external thread 7 engage with each other. As the degree of tightening increases, the sealing ring 3 at the bottom of the bottle cap 1 and the bottle body 6 are in closer contact with each other, thereby preventing the liquid in the bottle from leaking out.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
