Description

Technical Field

[0001] This utility model relates to the field of iodine bottle cap technology, and more specifically to a medical screwless iodine bottle cap structure. Background Technology

[0002] Iodine solution is a widely used disinfectant effective against bacteria, viruses, fungi, protozoa, and even some spores. Therefore, bottled iodine solution is commonly found in hospitals and clinics. When using this type of bottled iodine solution, medical staff usually need to unscrew the cap before pouring out the solution. Because the cap needs to be screwed back on after opening, the operation is cumbersome. Therefore, existing technology proposes a pop-up cap iodine solution bottle, as shown in publication number CN207917540U. This type of bottle can be opened without screwing on; simply pressing the button on the front of the cap opens it, and closing it is just as simple, making the operation much simpler.

[0003] These bottle caps are similar to the Lock & Lock lids used in thermos cups on the market. However, these bottle caps have the following shortcomings: if the iodine bottle is placed in a first aid kit, it is easy for the button on the front to be pressed by surrounding objects, causing the bottle cap to open accidentally. As a result, the iodine in the bottle can easily spill out, causing leakage. It is evident that the safety of this type of bottle cap is insufficient. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a medical iodine solution bottle cap structure that uses a top-to-bottom pressing method to open the large piston. The piston control button is embedded inside the outer cap, which can further prevent accidental opening caused by the pressure of surrounding objects, thereby avoiding leakage of iodine solution inside the bottle and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical no-twist iodine bottle cap structure, comprising an outer cap threadedly connected to the mouth of an iodine bottle, an inner ring plate fixed inside the outer cap, the outer wall of the inner ring plate contacting the inner wall of the iodine bottle mouth, a large piston inside the inner ring plate, and a piston control button on the top of the large piston. When the piston control button is pressed down for the first time, pushing the large piston out from the bottom of the inner ring plate, iodine in the iodine bottle flows out from the gap between the inner ring plate and the large piston. When the piston control button is pressed down for the second time, causing the large piston to move back up to the bottom of the inner ring plate, the gap between the inner ring plate and the large piston is blocked to prevent iodine from flowing out.

[0006] In a preferred embodiment, the piston control button includes a hollow cylinder fixed in the middle of the outer cover. The top of the hollow cylinder is flush with the top of the outer cover, and the bottom of the hollow cylinder extends into the interior of the outer cover. The top of the large piston contacts the bottom of the hollow cylinder. A partition is fixed inside the hollow cylinder, and a button plate is provided on the top of the partition. A vertical rod is fixed at the bottom of the button plate, and the bottom end of the vertical rod passes through the partition and is fixed to the top of the large piston. When the button plate is pressed and moved, it drives the large piston to move through the vertical rod.

[0007] The top of the partition is equipped with a limiting component for locking the large piston in its downward position. When the button is pressed again, the limiting component releases the lock on the large piston.

[0008] In a preferred embodiment, the limiting component includes a heart-shaped groove formed on a vertical rod, the heart-shaped groove being located above a partition, a limiting rod being provided on one side of the top of the partition, one end of the limiting rod being inserted into the heart-shaped groove, and a rotating ball being fixed to the other end of the limiting rod, the rotating ball being embedded inside the partition to allow the limiting rod to swing left and right.

[0009] In a preferred embodiment, a spring is fixed to the bottom of the button panel, the spring is sleeved outside the vertical rod, and the spring is located at the top of the partition.

[0010] In a preferred embodiment, a small piston is fixed to the outer end of the vertical rod. The small piston is located below the partition and is used to prevent iodine from flowing to the top of the partition.

[0011] In a preferred embodiment, an opening is provided on one side of the top of the outer cover, and a dustproof plate for blocking the opening is provided in the top wall of the outer cover;

[0012] The dustproof plate includes a baffle inserted into the opening. A baffle groove for accommodating the baffle is provided on one side of the top of the outer cover. When the baffle is rotated into the baffle groove, the opening is exposed to allow iodine to flow out. When the baffle is rotated into the opening, the channel through which iodine flows is blocked to prevent dust from entering its interior.

[0013] In a preferred embodiment, a slot for easy finger insertion is provided on one side of the baffle.

[0014] In a preferred embodiment, one end of the baffle is provided with a protrusion, which is used to confine the baffle inside the baffle groove after rotation. This arrangement allows the baffle to be easily rotated into the baffle groove so that the opening can be exposed for the iodine solution in the bottle to flow out.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By installing the piston control button that controls the movement of the large piston in the middle of the outer cover, the large piston can be opened by pressing from top to bottom. The piston control button is embedded inside the outer cover, which can further prevent accidental opening caused by the pressure of surrounding items, thereby avoiding leakage of iodine solution inside the bottle.

[0017] 2. This utility model uses a piston control button to push the large piston down to open the bottle, and then presses the piston control button again to push the large piston up to close the bottle. The bottle cap can be opened and closed with just two presses, which simplifies the operation of the iodine bottle and makes it easier for medical staff to take the iodine from the bottle.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Refer to the instruction manual appendix Figure 1-3 and Figure 5 This utility model provides a screwless cap structure for a medical iodine solution bottle, including an outer cap 1 threadedly connected to the mouth of an iodine solution bottle 6. An opening is provided on one side of the top of the outer cap 1. An inner ring plate 2 is fixed inside the outer cap 1. In use, the inner ring plate 2 needs to be inserted into the mouth of the iodine solution bottle 6, so that the outer wall of the inner ring plate 2 contacts the inner wall of the mouth of the iodine solution bottle 6. Then, the outer cap 1 is rotated to screw it onto the outside of the mouth of the iodine solution bottle 6, so that it... Figure 2 As shown;

[0032] A large piston 3 is provided inside the inner ring plate 2, and a piston control button 4 is provided on the top of the large piston 3, as detailed below. Figure 4-7 As shown, the piston control button 4 includes a hollow cylinder 41 fixed in the middle of the outer cover 1. The top of the hollow cylinder 41 is flush with the top of the outer cover 1, and the bottom of the hollow cylinder 41 extends into the interior of the outer cover 1. The top of the large piston 3 contacts the bottom of the hollow cylinder 41. A partition is fixed inside the hollow cylinder 41. A button plate 44 is provided on the top of the partition. A vertical rod 42 and a spring 45 are fixed at the bottom of the button plate 44. The spring 45 is sleeved on the outside of the vertical rod 42, and the bottom of the spring 45 is fixed to the top of the partition.

[0033] The bottom end of the vertical rod 42 passes through the partition and is fixed to the top of the large piston 3. When the button plate 44 is pressed and moved, the large piston 3 is moved through the vertical rod 42. The top of the partition is provided with a limiting component 46 that locks the downward position of the large piston 3. When the button plate 44 is pressed again, the limiting component 46 pushes the vertical rod 42 to move the large piston 3 upward.

[0034] In this embodiment, the structure of the limiting component 46 is as follows: Figure 6 and Figure 7 As shown: including a heart-shaped groove 461 formed on the vertical rod 42, the shape of the heart-shaped groove 461 is as follows Figure 7 The diagram shows two channels, left and right. The heart-shaped groove 461 is located on the partition. A limiting rod 462 is provided on one side of the top of the partition. One end of the limiting rod 462 is inserted into the heart-shaped groove 461, and a rotating ball 463 is fixed to the other end of the limiting rod 462. The rotating ball 463 is embedded in the partition so that the limiting rod 462 can swing left and right.

[0035] When medical staff need to pour out the iodine in the iodine bottle 6, they can press the button 44 downwards with their fingers so that the button 44 can push the large piston 3 downwards through the vertical rod 42. After the large piston 3 is moved down, it will move away from the bottom of the inner ring plate 2 and leave a gap between it and the bottom of the inner ring plate 2. At this time, medical staff can tilt the iodine bottle 6 so that the iodine in the iodine bottle 6 can flow out through the gap. Then, the flowing iodine flows out through the opening at the top of the outer cap 1, which makes it easy to pour out the iodine inside the iodine bottle 6.

[0036] During the above process, when the button plate 44 is pressed for the first time, the limiting rod 462 installed in the hollow cylinder 41 will move along the left channel of the heart groove 461 to the middle position of the top of the heart groove 461. Since the middle position of the top of the heart groove 461 is set to be concave, the limiting rod 462 will be restricted by the position after it moves to this position, thereby locking the position of the vertical rod 42 at this time, so that the large piston 3 can be kept in the position at the bottom of the inner ring plate 2, so that iodine can flow out.

[0037] When the bottle cap needs to be closed, the button panel 44 can be pressed a second time. At this time, one end of the limiting rod 462, which was originally located in the middle of the top of the heart-shaped groove 461, will move along the right-side channel to the bottom of the heart-shaped groove 461. Figure 7 The button plate 44 is positioned as shown to release the original lock on the large piston 3. The first press of the button plate 44 also compresses the spring 45, placing it in a compressed state. Therefore, after the lock is released, the compressed spring 45 pushes the button plate 44 upwards, thereby enabling the large piston 3 to move upwards via the vertical rod 42, allowing it to move as shown. Figure 6 The opening at the bottom of the inner ring plate 2 is sealed to prevent the leakage of iodine solution. This invention uses a two-press method to open and close the bottle cap, which is simple to operate. Moreover, by installing the button plate 44 inside the outer cover 1, it can also prevent the bottle cap from being accidentally opened due to pressure from other objects, which is conducive to further preventing iodine solution leakage and improving safety.

[0038] Furthermore, in this embodiment, a small piston 43 is fixed to the outer end of the vertical rod 42. The small piston 43 is located below the partition plate. The small piston 43 can prevent the iodine flowing above the large piston 3 from flowing to the bottom of the partition plate, thereby preventing it from flowing to the top of the partition plate and causing leakage, thus improving the leak prevention effect.

[0039] Since iodine solution needs to flow out through the opening at the top of the outer cover 1 and the channel between the inner wall of the inner ring plate 2 and the outer wall of the hollow cylinder 41, in order to prevent dust from falling into the opening and the channel, such as Figure 1 and Figure 2 As shown, a dustproof plate 5 for blocking the opening is also provided in the top wall of the outer cover 1;

[0040] Specifically, such as Figure 4-6 As shown: The dustproof plate 5 includes a baffle 51 inserted into the opening. The top side of the outer cover 1 is provided with a baffle groove 52 for accommodating the baffle 51. A protrusion is also processed at one end of the baffle 51. The protrusion is used to restrict the baffle 51 inside the baffle groove 52 after rotation. This setting can facilitate the rotation of the baffle 51 into the baffle groove 52 so as to expose the opening for the iodine in the bottle to flow out.

[0041] A slot 53 is provided on one side of the baffle 51 to facilitate finger insertion. Before pressing the button plate 44, the baffle 51 must be rotated through the slot 53 to rotate the baffle 51 into the baffle groove 52 to expose the opening. Then, the button plate 44 is pressed again to facilitate the flow of iodine. After pressing the button plate 44 a second time, the baffle 51 can be rotated back into the opening to block the opening and the channel for the flow of iodine, preventing dust from entering and maintaining cleanliness and hygiene.

[0042] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
