Description

Technical Field

[0001] The utility model relates to the technical field of containers, in particular to a pressure-resistant polymer vacuum bottle based on an inner and outer cover buckle structure. Background Art

[0002] A vacuum bottle, or lotion bottle, is a container that can isolate gas from the outside temperature or isolate external bacteria. Its working principle is to use the contraction force of the spring to prevent air from entering the bottle, creating a vacuum state, and use atmospheric pressure to push the piston at the bottom of the bottle forward.

[0003] The existing vacuum bottles still have the following problems during use:

[0004] Some existing vacuum bottles have complex structures and high production costs. In addition, when some vacuum bottles accidentally fall to the ground or are subjected to strong impact, the protective outer cover on the top is easy to fall off. The wear caused by long-term opening and closing will gradually reduce the locking effect of the outer cover, and the use effect is not good enough.

[0005] In view of the above problems, the utility model document proposes a pressure-resistant polymer vacuum bottle based on an inner and outer cover buckle structure. Utility Model Content

[0006] The utility model aims to solve the shortcomings of the prior art that the production cost of vacuum bottles is high and the fixing effect of the protective outer cover is not good enough, and proposes a pressure-resistant polymer vacuum bottle based on the buckling structure of the inner and outer covers.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0015] In a possible design, the outer diameter of the second piston block is greater than the outer diameter of the connecting tube, which can ensure that when the second piston block is sealed with the groove, no liquid enters the connecting tube through the liquid inlet hole.

[0016] In a possible design, the outer wall of the mounting seat is provided with anti-slip textures to facilitate its rotation.

[0017] In the present application, when in use, the user only needs to press the pressing head, at which time the pressing head drives the connecting tube to descend, thereby pushing the second piston block out of the sealing groove. When the second piston block moves to the outside of the sealing groove, the liquid in the bottle body will enter the connecting tube through the liquid inlet hole, and then enter the liquid outlet channel, and finally be discharged from one end of the liquid outlet tube; as a part of the liquid in the bottle body is reduced, the first piston block will move upward under the push of the external atmospheric pressure, completing the gradual push of the liquid; when the user stops pressing, the second piston block is retracted into the sealing groove under the action of the compression spring, completing the connection The blocking and sealing of the connecting pipe means that the liquid will no longer be discharged and it is difficult for outside air to enter the bottle body, so the use effect is better.

At this time, the outer cover and the inner cover can be snapped and fixed. When releasing, only a slight rotation is needed, and the installation groove can be used to complete the detachment of the outer cover. The operation is simple and the use effect is good.
