Description

Technical Field

[0001] The utility model relates to the technical field of reagent bottles, in particular to a leak-proof reagent bottle. Background Art

[0002] Reagent bottles are containers for storing liquid or solid chemical reagents, and they play a vital role in chemical laboratories.

[0003] In chemical laboratories, some reagents need to be sealed during storage to prevent leakage due to volatilization. Traditional reagent bottles usually use rubber sealing rings to seal the bottle mouth and bottle cap. However, ammonia, concentrated hydrochloric acid and concentrated nitric acid are volatile liquids that are corrosive to rubber sealing rings. Long-term use will cause the rubber sealing rings to be damaged, affecting their sealing effect. This requires staff to frequently replace them, which is too troublesome. Moreover, when staff replace the rubber sealing rings, the bottle mouth is exposed to the air, which further increases the volatilization of the reagents and causes the reagents to leak. Utility Model Content

[0007] It also includes a bottle cap threadedly sleeved on the surface of the bottle mouth, a sealing cover is arranged inside the bottle cap, and the sealing cover matches the fixing groove, so that when the bottle cap is threadedly sleeved on the bottle mouth, the front end of the sealing cover is embedded in the fixing groove, and a plurality of pointed cones are fixedly installed on the lower surface of the sealing cover.

[0008] The utility model has the following beneficial effects: when ammonia water, concentrated hydrochloric acid or concentrated nitric acid needs to be stored for a long time, the ammonia water, concentrated hydrochloric acid or concentrated nitric acid to be stored is placed inside the bottle body, and the oil bag is placed in the fixed groove. At this time, the bottle cap is screwed on, and when the bottle cap is gradually sleeved on the bottle mouth, the sealing cover inside the bottle cap moves downward, and the pointed cone on the lower surface of the sealing cover contacts the oil bag and gradually penetrates into the oil bag. When the sealing cover drives the pointed cone to rotate, the pointed cone gradually cuts the oil bag, so that the mineral oil inside the oil bag can fill the inner bottom of the fixed groove, thereby sealing the bottle mouth; the ammonia water, concentrated hydrochloric acid or concentrated nitric acid is sealed by adopting the mineral oil oil seal. Since the mineral oil is difficult to react with the ammonia water, concentrated hydrochloric acid or concentrated nitric acid, the reagent bottle can effectively seal and store the ammonia water, concentrated hydrochloric acid or concentrated nitric acid for a long time to avoid leakage. In addition, the staff does not need to frequently open the bottle cap for maintenance or replacement, which reduces the workload of the staff and avoids the increased volatilization of the ammonia water, concentrated hydrochloric acid or concentrated nitric acid during the opening process, resulting in leakage.

[0023] like Figures 1 to 5 As shown, Embodiment 1 of the utility model is a leak-proof reagent bottle, comprising a bottle body 1, the top of the bottle body 1 is connected with a bottle mouth 2, the top of the bottle mouth 2 is provided with an annular fixing groove 3, an oil bag is placed on the inner bottom wall of the fixing groove 3, and the oil bag is filled with mineral oil;

[0024] It also includes a bottle cap 4 which is threadedly sleeved on the surface of the bottle mouth 2, and a sealing cover 5 is arranged inside the bottle cap 4. The sealing cover 5 matches the fixing groove 3 so that when the bottle cap 4 is threadedly sleeved on the bottle mouth 2, the front end of the sealing cover 5 is embedded in the fixing groove 3, and a plurality of pointed cones 6 are fixedly installed on the lower surface of the sealing cover 5.

[0025] When ammonia water, concentrated hydrochloric acid or concentrated nitric acid needs to be stored for a long time, the ammonia water, concentrated hydrochloric acid or concentrated nitric acid to be stored is placed inside the bottle body 1, and the oil bag is placed in the fixed groove 3. At this time, the bottle cap 4 is screwed on. When the bottle cap 4 is gradually sleeved on the bottle mouth 2, the sealing cover 5 inside the bottle cap 4 moves downward, and the pointed cone 6 on the lower surface of the sealing cover 5 contacts the oil bag and gradually penetrates into the oil bag. When the sealing cover 5 drives the pointed cone 6 to rotate, the pointed cone 6 gradually cuts the oil bag, so that the mineral oil inside the oil bag can fill the fixed groove 3. The inner bottom of the groove 3 is sealed to seal the bottle mouth 2; the ammonia water, concentrated hydrochloric acid or concentrated nitric acid are sealed by adopting mineral oil seal. Since mineral oil is difficult to react with ammonia water, concentrated hydrochloric acid or concentrated nitric acid, the reagent bottle can effectively seal and store ammonia water, concentrated hydrochloric acid or concentrated nitric acid for a long time to avoid leakage. In addition, the staff does not need to frequently open the bottle cap for maintenance or replacement, which reduces the workload of the staff and avoids the increase of volatilization of ammonia water, concentrated hydrochloric acid or concentrated nitric acid during the opening process, which leads to leakage.

[0026] In summary of the specific implementation, the bottle cap 4 , the sealing cap 5 and the bottle mouth 2 can be made of transparent material, so that the staff can observe the oil capsule in the fixed groove 3 to ensure that the oil capsule is ruptured and the mineral oil inside the oil capsule flows out to fill the fixed groove 3 .
