Description

Technical Field

[0001] The utility model relates to the technical field of glass bottles, and specifically relates to a sealing device for a glass bottle. Background Technique

[0002] As a container for holding substances, a glass bottle has the advantages of being clean and pollution-free, corrosion-resistant, easy to clean, low cost, and reusable. Therefore, it is widely used in the fields of medicine, chemical industry, fast-moving consumer goods, and daily life. In daily life, it can not only be used to make and drink tea, store items, but also hold edible seasonings; however, most glass bottles are used for storing liquids.

[0003] Currently, when sealing a glass bottle, most often a bottle cap is used to seal the opening of the glass bottle to prevent the liquid from flowing out of the inside of the glass bottle. However, since most glass bottles are sealed only by a single layer of the bottle cap, and the glass bottle will shake during transportation. If the bottle cap of the glass bottle is not sealed tightly, the liquid inside the glass bottle is likely to leak through the bottle mouth, causing economic losses, and thus resulting in relatively poor sealing performance of the bottle mouth of the glass bottle. In view of this, we have developed a sealing device for a glass bottle. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sealing device for a glass bottle to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sealing device for a glass bottle, comprising: a bottle body, a bottle mouth, and a bottle cap;

[0006] The bottle mouth is arranged at the top of the bottle body, and the bottle mouth and the bottle body are integrally formed. An external thread is provided on the surface of the bottle mouth, and the external thread and the bottle mouth are integrally formed. The bottle cap is arranged on the surface of the bottle mouth. A chute is provided inside the bottle cap, and the chute and the bottle cap are integrally formed. An L-shaped sealing block is slidably connected inside the chute. The number of the L-shaped sealing blocks is two groups. Sealing air bags are arranged at the tops of the two groups of L-shaped sealing blocks. The arrangement of the sealing air bags can seal the central opening on the surface of the bottle mouth. A sealing mechanism is arranged inside the bottle cap. The second spring of the sealing mechanism drives a moving plate and a first sealing ring to move, so that the first sealing ring contacts the external thread.

[0007] Preferably, the sealing mechanism includes a positioning cavity formed inside the bottle cap. The positioning cavity and the bottle cap are integrally formed. The second spring is connected inside the positioning cavity. One end of the second spring is connected to a moving plate. The upper and lower ends of the moving plate are respectively in contact with the inner wall of the positioning cavity. When the moving plate moves, it will move inside the positioning cavity. Thus, by the setting of the positioning cavity, the movement of the moving plate can be limited, enabling the moving plate to always move horizontally to the left and right. The first sealing ring is connected to one side of the moving plate, and the moving plate penetrates the bottle cap.

[0008] Preferably, a threaded rod is screwed inside the bottle cap. One end of the threaded rod is connected to a turntable. The turntable and the threaded rod are welded. The other end of the turntable is connected to a second sealing ring. The turntable and the second sealing ring are fixedly arranged.

[0009] Preferably, a placement cavity for placing the second sealing ring is formed inside the bottle cap. The placement cavity and the bottle cap are integrally formed.

[0010] Preferably, the top of the bottle body is connected to a bottleneck. The bottleneck and the bottle body are integrally formed.

[0011] Preferably, a first spring is arranged inside the chute and located at the L-shaped sealing block. After the first spring is squeezed by the L-shaped sealing block, the first spring is compressed. Also, the elastic force of the first spring itself can drive the L-shaped sealing block to move downward.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] (1) By the internal thread of the bottle cap matching and screwing with the external thread on the surface of the bottle mouth, the bottle cap moves on the surface of the bottle mouth. Then the top of the bottle mouth will squeeze the first sealing ring, causing the first sealing ring to drive the moving plate to move into the positioning cavity. Thus, the moving plate squeezes the second spring. The external thread on the surface of the bottle mouth will contact the first sealing ring. By the elastic force of the second spring itself, the moving plate and the first sealing ring will be driven to move outward, enabling the first sealing ring to enter the external thread on the surface of the bottle mouth, thereby clamping and sealing the surface of the bottle mouth, and further preventing leakage from occurring at the bottle mouth.

[0014] (2) When the top of the bottle mouth contacts the bottom of the L-shaped sealing block and the bottle cap is continuously rotated, the top of the bottle mouth will drive the L-shaped sealing block to slide inside the chute, causing the L-shaped sealing block to squeeze the first spring. The opening on the surface of the bottle mouth will seal the sealing airbag, further sealing the bottle mouth, forming a second seal, which is more convenient to use.

[0015] (3) Drive the threaded rod to rotate through the turntable. Since the external thread part on the surface of the threaded rod is matched and screwed with the internal thread inside the bottle cap, the threaded rod and the second sealing ring can be driven to move, and the second sealing ring will tightly adhere to the external thread on the surface of the bottle mouth, so that the external thread on the surface of the bottle mouth can be sealed for the third time by using the second sealing ring, thereby preventing the liquid inside the bottle body from flowing out.

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution: a sealing device for a glass bottle, including: a bottle body 1, a bottle mouth 3 and a bottle cap 5. The bottle mouth 3 is arranged at the top of the bottle body 1. An external thread 4 is provided on the surface of the bottle mouth 3. The bottle cap 5 is arranged on the surface of the bottle mouth 3. A chute 10 is provided inside the bottle cap 5. An L-shaped sealing block 9 is slidably connected inside the chute 10. The number of the L-shaped sealing blocks 9 is two groups. Sealing airbags 11 are arranged at the tops of the two groups of L-shaped sealing blocks 9. A sealing mechanism is arranged inside the bottle cap 5. The second spring 14 of the sealing mechanism drives the moving plate 15 and the first sealing ring 12 to move, so that the first sealing ring 12 contacts the external thread 4.

[0022] The sealing mechanism includes a positioning cavity 13 formed inside the bottle cap 5. A second spring 14 is connected inside the positioning cavity 13. A moving plate 15 is connected to one end of the second spring 14. The upper and lower ends of the moving plate 15 are in contact with the inner wall of the positioning cavity 13 respectively. A first sealing ring 12 is connected to one side of the moving plate 15, and the moving plate 15 penetrates through the bottle cap 5.

[0023] A threaded rod 7 is screwed inside the bottle cap 5. One end of the threaded rod 7 is connected with a turntable 6. The turntable 6 and the threaded rod 7 are welded. The other end of the turntable 6 is connected with a second sealing ring 16. The turntable 6 and the second sealing ring 16 are fixedly arranged.

[0024] A placement cavity 17 for placing the second sealing ring 16 is formed inside the bottle cap 5. The placement cavity 17 and the bottle cap 5 are integrally formed.

[0025] The top of the bottle body 1 is connected with a bottleneck 2. The bottleneck 2 and the bottle body 1 are integrally formed.

[0026] A first spring 8 is arranged inside the chute 10 and is located under the L-shaped sealing block 9. After the first spring 8 is squeezed by the L-shaped sealing block 9, the first spring 8 is compressed. Also, the elastic force of the first spring 8 itself can be used to drive the L-shaped sealing block 9 to move downward.

[0027] Specifically, during use, unscrew the bottle cap 5 so that the internal thread inside the bottle cap 5 is screwed and engaged with the external thread 4 on the surface of the bottle mouth 3, so that the bottle cap 5 can move on the surface of the bottle mouth 3. Continuously rotate the bottle cap 5, and the top of the bottle mouth 3 will contact the surface of the first sealing ring 12. After the bottle cap 5 continues to move downward, the top of the bottle mouth 3 will squeeze the first sealing ring 12, causing the first sealing ring 12 to drive the moving plate 15 to move into the positioning cavity 13, thereby squeezing the second spring 14 with the moving plate 15. The first sealing ring 12 and the moving plate 15 will enter the positioning cavity 13, and the external thread 4 on the surface of the bottle mouth 3 will contact the first sealing ring 12. At this time, the elastic force of the second spring 14 itself will drive the moving plate 15 and the first sealing ring 12 to move outward, allowing the first sealing ring 12 to enter the external thread 4 on the surface of the bottle mouth 3, thereby clamping and sealing the surface of the bottle mouth 3, and avoiding leakage of the bottle mouth 3.

[0028] The top of the bottle mouth 3 will contact the bottom of the L-shaped sealing block 9. Continuously rotate the bottle cap 5, and the top of the bottle mouth 3 will drive the L-shaped sealing block 9 to slide inside the chute 10, so that the L-shaped sealing block 9 squeezes the first spring 8. At this time, the opening on the surface of the bottle mouth 3 will seal the sealing airbag 11, further sealing the bottle mouth 3, forming a second seal, which is more convenient to use.

[0029] Next, turn the turntable 6, and use the turntable 6 to drive the threaded rod 7 to rotate. Since the external thread portion on the surface of the threaded rod 7 is matched and screwed with the internal thread inside the bottle cap 5, the threaded rod 7 and the second sealing ring 16 can be driven to move, so that the second sealing ring 16 leaves the inside of the placement cavity 17, and the second sealing ring 16 will tightly adhere to the external thread 4 on the surface of the bottle mouth 3, so as to use the second sealing ring 16 to perform the third sealing on the external thread 4 on the surface of the bottle mouth 3, thereby preventing the liquid inside the bottle body 1 from flowing out.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
