Description

Technical Field

[0001] The utility model belongs to the technical field of dropper bottles, and more specifically relates to a sealed dropper bottle. Background Art

[0002] Dropper bottles are used to store small amounts of liquid. Brown bottles are used when they need to be stored away from light. Dropper bottles have frosted inner sides and are similar to narrow-necked bottles. The bottle cap is replaced by a dropper. They are laboratory supplies mainly used to extract and add small amounts of liquid.

[0003] Traditional dropper bottles are all equipped with a rubber stopper on the dropper, and the rubber stopper is pressed against the inner wall of the bottle mouth to form a seal. However, this sealing method may be loose in actual use, and the rubber stopper may be worn after repeated use, resulting in leakage, which affects the storage of supplies. Therefore, a sealed dropper bottle is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a sealed dropping bottle, which can realize the sealing effect of the dropping bottle.

[0005] The utility model discloses a sealed dropper bottle, comprising a bottle body, a dropper and a rubber plug; the lower end of the dropper extends into the bottle body, the rubber plug is fixedly mounted on the dropper, the upper end of the bottle body is provided with a bottle mouth, the rubber plug abuts against the inner wall of the bottle mouth, and is characterized in that it also comprises a sealing ring, a movable disk, a limiting disk and a pressing plate; the lower end of the sealing ring is fixedly connected to the upper end surface of the bottle mouth, the upper end of the sealing ring is connected to the lower end surface of the movable disk, the limiting disk is fixedly connected to the bottle mouth, and the limiting disk is arranged above the movable disk; a clamping groove is provided on the limiting disk, one end of the pressing plate is fixedly connected to the rubber gasket, and the upper end of the pressing plate passes through the clamping groove and abuts against the upper end surface of the movable disk.

[0006] As a further improvement of the utility model, the middle part of the sealing ring bulges inwards in the natural rotation state.

[0007] As a further improvement of the utility model, the number of the card slots and the pressure plates are at least 4, and they are evenly distributed on the limit plate and the rubber plug along the circumferential direction.

[0008] As a further improvement of the utility model, the inner diameter of the upper end of the limiting disk is smaller than the inner diameter of the movable disk.

[0009] Compared with the prior art, the advantages of the present invention are:

[0010] The utility model can compress the movable disk through the pressure plate, thereby compressing the sealing ring, so that the sealing ring is compressed and deformed inwardly, and the sealing ring can further ensure the purpose of sealing, thereby effectively avoiding the leakage of experimental supplies, will not be affected by the wear of the rubber plug, and the sealing effect is better.

[0016] Specific embodiment 1: Please refer to Figure 1-3 A sealed dropper bottle comprises a bottle body 1, a dropper 2 and a rubber stopper 3; the lower end of the dropper 2 extends into the bottle body 1, the rubber stopper 3 is fixedly installed on the dropper 2, the upper end of the bottle body 1 is provided with a bottle mouth, and the rubber stopper 3 abuts against the inner wall of the bottle mouth.

[0017] It also includes a sealing ring 4, a movable disk 5, a limiting disk 6 and a pressing plate 7; the lower end of the sealing ring 4 is hot-melt connected to the upper end surface of the bottle mouth, the upper end of the sealing ring 4 is hot-melt connected to the lower end surface of the movable disk 5, the limiting disk 6 is connected to the bottle mouth by a fixing glue, and the limiting disk 6 is arranged above the movable disk 5; a card slot 8 is arranged on the limiting disk 6, one end of the pressing plate 7 is hot-melt connected to the rubber gasket, and the upper end of the pressing plate 7 passes through the card slot 8 and abuts against the upper end surface of the movable disk 5; by pressing the pressing plate 7 into the limiting disk 6, the movable disk 5 can be compressed, thereby driving the sealing ring 4 to deform inwards and abut against the rubber plug 3. , and then form a seal to ensure the sealing of the dropper bottle. At the same time, the middle part of the sealing ring 4 bulges inward under the natural rotation state, so that when the pressure plate presses the sealing ring 4 to deform, it can play a role of inward limiting guide, ensuring that the sealing ring 4 can stably fit with the rubber plug 3 to form a seal; the number of the card slots 8 and the pressure plate 7 are 4, and they are evenly distributed on the limiting disk 6 and the rubber plug 3 along the circumferential direction, respectively, which can compress the movable disk 5 more stably. The inner circle diameter of the upper end of the limiting disk 6 is smaller than the inner circle diameter of the movable disk 5, thereby avoiding the situation where the movable disk 5 is separated from the limiting disk 6.

[0018] Working principle: In the utility model, when the dropper 2 is inserted into the dropper bottle, the rubber stopper 3 abuts against the inner wall of the bottle mouth to form a first layer of sealing. At the same time, the pressure plate 7 passes through the slot 8 and abuts against the movable disk 5 to compress the sealing ring 4, so that the sealing ring 4 can fit the rubber stopper 3 to form a seal. Then the dropper 2 is rotated, and the pressure block is no longer aligned with the slot 8, thereby avoiding the dropper 2 from slipping.

[0019] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
