Description

Technical Field

[0001] This utility model relates to medical bottle cap structures, and more particularly to a twist-off bottle cap structure for a rinsing fluid container. Background Technology

[0002] In existing technologies, flushing fluid containers require a high degree of sealing, generally necessitating a highly effective sealing structure. This results in significant force being required to open the container during use, which can lead to serious consequences in emergencies such as surgery or first aid. Therefore, a flushing fluid bottle cap structure that ensures a tight seal while allowing for easy opening is needed.

[0003] For example, a Chinese patent document, "A Structure for a Fluid Bottle," with publication number CN202080529U, discloses a bottle body and a cap, which are fixedly connected. The cap includes a cover body, and the top of the cover body has a pull ring for opening the cap. The drawback of this patent is that opening the fluid bottle using the pull ring requires considerable force, which could easily affect the progress of surgery or emergency care in surgical or first-aid situations, potentially leading to serious consequences. Utility Model Content

[0004] This invention aims to overcome the problem that opening the cap of an irrigation fluid bottle is difficult in the prior art, which can easily affect the progress of surgery or emergency treatment. It provides a twist-off cap structure for an irrigation fluid container, which allows the irrigation fluid bottle to be opened quickly by twisting off the cap structure, thereby gaining more time for rescue.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a twist-off cap structure for a rinsing liquid container, comprising an inner cap and an outer cap, wherein the outer cap is fitted over the inner cap, and the inner cap includes a bottle mouth portion and a twist-off portion, wherein an easy-break opening is provided at the connection between the bottle mouth portion and the twist-off portion.

[0007] The twist-off portion and fracturing point in this application allow the bottle cap to be opened quickly. The inner cap forms a completely sealed structure with the bottle body, ensuring the bottle's airtightness. The outer cap, fitted over the inner cap, prevents accidental contact with the twist-off portion and forms a second layer of seal, further enhancing the airtightness.

[0008] Preferably, a sealing structure is provided between the inner cover and the outer cover.

[0009] Preferably, the sealing structure includes a sealing portion disposed on the inner cover that is interference-fitted with the inner wall of the outer cover.

[0010] Preferably, the sealing structure includes a sealing ring mounted on the inner cover.

[0011] Preferably, the torn portion has a sheet-like structure with a thickness of 1-5 mm.

[0012] Preferably, an inner cavity is provided below the twisted part, and the lower side of the inner cavity communicates with the opening of the bottle mouth.

[0013] Preferably, the outer side of the inner cover is provided with an external thread portion, and the inner side of the outer cover is provided with an internal thread portion that is adapted to the external thread portion.

[0014] Preferably, the inner side of the outer cover is provided with a torsion force application part located on one side of the torsion part.

[0015] Preferably, the side of the torsion section is provided with anti-slip protrusions.

[0016] Therefore, the present invention has the following beneficial effects: (1) the structure at the twisted cap can quickly open the rinsing liquid bottle, thereby gaining more rescue time; (2) the inner and outer caps can prevent the twisted part from being accidentally touched and improve the sealing performance.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1, as Figure 1As shown, a twist-off cap structure for a rinsing fluid container includes an inner cap 1 and an outer cap 2. The outer cap 2 is fitted over the inner cap 1. The inner cap 1 includes a bottle mouth portion 3 and a twist-off portion 4. An easy-break point 5 is provided at the connection between the bottle mouth portion 3 and the twist-off portion 4. The twist-off portion 4 and the easy-break point 5 allow the cap to be opened quickly. The outer cap 2, fitted over the inner cap 1, prevents accidental contact with the twist-off portion 4 and forms a second layer of seal, further improving the sealing performance. Both the inner cap 1 and the outer cap 2 are made of polypropylene, which is non-toxic, odorless, lightweight, convenient for transportation and use, and is an environmentally friendly material.

[0025] The inner cap 1 is integrated with the bottle body to form a completely sealed structure, ensuring the bottle's airtightness. The wall thickness at the easily broken part 5 does not exceed one-third of the wall thickness of the bottle mouth 3. The upper end of the bottle mouth 3 has an opening, which is circular in shape. The lower end of the twisted part 4 has an inner cavity 6, the lower side of which communicates with the opening of the bottle mouth 3. By providing the inner cavity 6, sufficient deformation can be achieved at the connection between the twisted part 4 and the bottle mouth 3, making it easier to break. If the inner cavity 6 is not present, the twisted part 4 is a solid structure, with less deformation under torsional force, making it less prone to breakage. The twisted part 4 is a sheet-like structure with a thickness of 1-5mm. Its outline shape can be square, circular, hexagonal, or other shapes that are easy for the user to pinch with their fingers. The sheet-like structure makes it easy for the user to pinch and rotate with one hand, and it is also easier to break during twisting compared to the circular opening of the bottle mouth 3. The length direction of the twisted part 4 is the same as the radial direction of the bottle body.

[0026] A threaded structure 7 is provided between the inner cap 1 and the outer cap 2. The outer side of the bottle mouth 3 of the inner cap 1 is provided with an external thread, and the inner side of the outer cap 2 is provided with an internal thread that matches the external thread. This structure can achieve relative fixation of the inner cap 1 and the outer cap 2, and the outer cap 2 will not come off easily, which is convenient for protecting the inner cap 1 during transportation and storage.

[0027] A sealing structure is provided between the inner cover 1 and the outer cover 2. The sealing structure includes a sealing part 8 disposed on the inner cover 1, which is interference-fitted with the inner wall of the outer cover 2. The sealing part 8 is located below the external threaded part. The sealing structure can maintain the seal of the liquid inside the bottle even after the bottle has been opened once. Although it cannot achieve a complete seal as before the twisted part 4 is disconnected, it can prevent external air from contacting the flushing liquid and prevent the flushing liquid from being contaminated.

[0028] During container transportation and storage, both the outer cap 2 and the inner cap 1 provide a seal, with the outer cap 2 also protecting the inner cap 1. After the container enters the medical room, the outer cap 2 can be removed by unscrewing it, putting the container in a ready-to-use state, while the inner cap 1 continues to seal the flushing solution. When the flushing solution needs to be used, the operator simply twists the breakage part 4, causing it to break at the break point 5, thus opening the flushing solution bottle. If the flushing solution in the bottle is not used immediately, the outer cap 2 can be replaced to protect the solution and prevent contamination.

[0029] Example 2, as Figure 2 As shown, a twist-off cap structure for a rinsing fluid container includes an inner cap 1 and an outer cap 2. The outer cap 2 is fitted over the inner cap 1. The inner cap 1 includes a bottle mouth portion 3 and a twist-off portion 4. An easy-break point 5 is provided at the connection between the bottle mouth portion 3 and the twist-off portion 4. The twist-off portion 4 and the easy-break point 5 allow the cap to be opened quickly. The outer cap 2, fitted over the inner cap 1, prevents accidental contact with the twist-off portion 4 and forms a second layer of seal, further improving the sealing performance. Both the inner cap 1 and the outer cap 2 are made of polypropylene, which is non-toxic, odorless, lightweight, convenient for transportation and use, and is an environmentally friendly material.

[0030] The inner cap 1 is integrated with the bottle body to form a completely sealed structure, ensuring the bottle's airtightness. The wall thickness at the easily broken part 5 does not exceed one-third of the wall thickness of the bottle mouth 3. The upper end of the bottle mouth 3 has an opening, which is circular in shape. The lower end of the twisted part 4 has an inner cavity 6, the lower side of which communicates with the opening of the bottle mouth 3. By providing the inner cavity 6, sufficient deformation can be achieved at the connection between the twisted part 4 and the bottle mouth 3, making it easier to break. If the inner cavity 6 is not present, the twisted part 4 is a solid structure, with less deformation under torsional force, making it less prone to breakage. The twisted part 4 is a sheet-like structure with a thickness of 1-5mm. Its outline shape can be square, circular, hexagonal, or other shapes that are easy for the user to pinch with their fingers. The sheet-like structure makes it easy for the user to pinch and rotate with one hand, and it is also easier to break during twisting compared to the circular opening of the bottle mouth 3. The length direction of the twisted part 4 is the same as the radial direction of the bottle body.

[0031] The side of the twisted part 4 is provided with anti-slip protrusions 10. These protrusions 10 increase the friction between the twisted part 4 and the operator's fingers when the operator grips it, thus preventing slippage and making the twisting process easier. Furthermore, the position of the anti-slip protrusions 10 is ergonomically designed. Alternatively, the anti-slip protrusions 10 can be replaced with anti-slip recesses, anti-slip stripes, or other structures that also increase friction.

[0032] A threaded structure 7 is provided between the inner cap 1 and the outer cap 2. The outer side of the bottle mouth 3 of the inner cap 1 is provided with an external thread, and the inner side of the outer cap 2 is provided with an internal thread that matches the external thread. This structure can achieve relative fixation of the inner cap 1 and the outer cap 2, and the outer cap 2 will not come off easily, which is convenient for protecting the inner cap 1 during transportation and storage.

[0033] A sealing structure is provided between the inner cover 1 and the outer cover 2. The sealing structure includes a sealing part 8 disposed on the inner cover 1, which is interference-fitted with the inner wall of the outer cover 2. The sealing part 8 is located below the external threaded part. The sealing structure can maintain the seal of the liquid inside the bottle even after the bottle has been opened once. Although it cannot achieve a complete seal as before the twisted part 4 is disconnected, it can prevent external air from contacting the flushing liquid and prevent the flushing liquid from being contaminated.

[0034] During container transportation and storage, both the outer cap 2 and the inner cap 1 provide a seal, with the outer cap 2 also protecting the inner cap 1. After the container enters the medical room, the outer cap 2 can be removed by unscrewing it, putting the container in a ready-to-use state, while the inner cap 1 continues to seal the flushing solution. When the flushing solution needs to be used, the operator simply twists the breakage part 4, causing it to break at the break point 5, thus opening the flushing solution bottle. If the flushing solution in the bottle is not used immediately, the outer cap 2 can be replaced to protect the solution and prevent contamination.

[0035] Example 3, as Figure 3 As shown, a twist-off cap structure for a rinsing fluid container includes an inner cap 1 and an outer cap 2. The outer cap 2 is fitted over the inner cap 1. The inner cap 1 includes a bottle mouth portion 3 and a twist-off portion 4. An easy-break point 5 is provided at the connection between the bottle mouth portion 3 and the twist-off portion 4. The twist-off portion 4 and the easy-break point 5 allow the cap to be opened quickly. The outer cap 2, fitted over the inner cap 1, prevents accidental contact with the twist-off portion 4 and forms a second layer of seal, further improving the sealing performance. Both the inner cap 1 and the outer cap 2 are made of polypropylene, which is non-toxic, odorless, lightweight, convenient for transportation and use, and is an environmentally friendly material.

[0036] The inner cap 1 is integrated with the bottle body to form a completely sealed structure, ensuring the bottle's airtightness. The wall thickness at the easily broken part 5 does not exceed one-third of the wall thickness of the bottle mouth 3. The upper end of the bottle mouth 3 has an opening, which is circular in shape. The lower end of the twisted part 4 has an inner cavity 6, the lower side of which communicates with the opening of the bottle mouth 3. By providing the inner cavity 6, sufficient deformation can be achieved at the connection between the twisted part 4 and the bottle mouth 3, making it easier to break. If the inner cavity 6 is not present, the twisted part 4 is a solid structure, with less deformation under torsional force, making it less prone to breakage. The twisted part 4 is a sheet-like structure with a thickness of 1-5mm. Its outline shape can be square, circular, hexagonal, or other shapes that are easy for the user to pinch with their fingers. The sheet-like structure makes it easy for the user to pinch and rotate with one hand, and it is also easier to break during twisting compared to the circular opening of the bottle mouth 3. The length direction of the twisted part 4 is the same as the radial direction of the bottle body.

[0037] A sealing structure is provided between the inner cover 1 and the outer cover 2. The sealing structure includes a sealing part 8 disposed on the inner cover 1, which is interference-fitted with the inner wall of the outer cover 2. In this embodiment, a threaded structure 7 is not provided; instead, the outer cover 2 and the inner cover 1 are fixed entirely by interference fit. The sealing structure allows the liquid inside the bottle to remain sealed even after the bottle has been opened once. Although a complete seal cannot be achieved as before the twisted-off part 4 is disconnected, it prevents external air from contacting the flushing liquid and avoids contamination of the flushing liquid.

[0038] During container transportation and storage, both the outer cap 2 and the inner cap 1 provide a seal, with the outer cap 2 also protecting the inner cap 1. After the container enters the medical room, the outer cap 2 can be removed by unscrewing it, putting the container in a ready-to-use state, while the inner cap 1 continues to seal the flushing solution. When the flushing solution needs to be used, the operator simply twists the breakage part 4, causing it to break at the break point 5, thus opening the flushing solution bottle. If the flushing solution in the bottle is not used immediately, the outer cap 2 can be replaced to protect the solution and prevent contamination.

[0039] Example 4, as Figure 4 As shown, a twist-off cap structure for a rinsing fluid container includes an inner cap 1 and an outer cap 2. The outer cap 2 is fitted over the inner cap 1. The inner cap 1 includes a bottle mouth portion 3 and a twist-off portion 4. An easy-break point 5 is provided at the connection between the bottle mouth portion 3 and the twist-off portion 4. The twist-off portion 4 and the easy-break point 5 allow the cap to be opened quickly. The outer cap 2, fitted over the inner cap 1, prevents accidental contact with the twist-off portion 4 and forms a second layer of seal, further improving the sealing performance.
