Description

Technical Field

[0001] This utility model relates to a vacuum bottle with a rotatable and liftable dust cover. Background Technology

[0002] Currently, existing cosmetic packaging bottles have the following disadvantages:

[0003] (1) The pump head of the packaging bottle is equipped with a dust cover. The dust cover protects the pump head from damage and contamination and prevents it from being opened. However, the cover is configured independently. Each time, the dust cover needs to be opened by pulling force to expose the pump head. After use, the cover needs to be closed again, which is inconvenient. Moreover, the dust cover is easy to lose during use. In addition, this packaging material has a single structure and lacks novelty, which cannot attract consumers well.

[0004] (2) There are also some rotating lifting caps, but during packaging or accidental drops, the caps are prone to damage and leakage. For example, the patent application number CN201821221445.2 discloses a press-type vacuum pump. In actual use, it was found that the cap structure was difficult to match the drop test conditions of different companies. After a drop, the structure is prone to not rotating smoothly, which poses a risk of leakage. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a vacuum bottle with a rotatable and liftable dust cover. The dust cover can cover or expose the cap by rotating and lifting. It has a simple structure, a novel opening method, a reasonable design, an attractive appearance, is convenient to use and carry, and has good safety and stability.

[0006] The technical solution to achieve the above objective is: a vacuum bottle with a rotatable and liftable dust cover, comprising an outer bottle, an inner bottle, a shoulder sleeve, a pump core, a button cap, a dust cover, and a guide ring, wherein:

[0007] The inner bottle is disposed inside the outer bottle, and a piston is interference-fitted inside the inner bottle;

[0008] The shoulder sleeve includes an inner sleeve, a middle sleeve, and an outer sleeve arranged sequentially from the inside to the outside. The middle part of the inner sleeve, the top of the middle sleeve, and the bottom of the outer sleeve are connected by an annular plate. The bottom of the outer sleeve is provided with a shoulder sleeve annular buckle.

The outer ends of the two cover bosses are slidably inserted into the rotating guide grooves one by one. When the guide ring is rotated, each cover boss slides along the corresponding rotating guide groove and boss slot, and drives the dust cover to rotate up or down.

[0015] The aforementioned vacuum bottle with a rotatable and liftable dust cover has each boss slot having a vertical part and a horizontally closed part at its upper and lower ends. Each boss slot is Z-shaped, and a boss guide groove is opened above the Z-shape to facilitate boss assembly.

[0016] In the aforementioned vacuum bottle with a rotatable and liftable dust cover, the bottom end of the inner wall of the guide ring is provided with an annular groove, and the outer wall of the shoulder sleeve outer cylinder is provided with an annular slide, the annular slide being slidably disposed in the annular groove.

[0017] The dust cover of this utility model, which can be rotated and raised, is a vacuum bottle with the following beneficial effects:

[0018] (1) The dust cover is designed to rotate and lift on the shoulder cover; the bottle body is a vacuum-sealed structure, which does not need to be opened when in use, and the contents of the bottle do not come into contact with the air, thus preventing contamination.

[0019] (2) After the dust cover is rotated up, it can block the entire button cap, which can prevent the nozzle from being contaminated, protect and seal it. After the dust cover is rotated down, the entire button cap can be exposed. At this time, the button cap can be pressed to pump the material out.

[0020] (3) The top of the boss slot on the shoulder sleeve is designed as a closed structure and there is a certain distance between it and the top of the shoulder sleeve. This design can better protect the bottle from deformation after falling and protect the dust cover from being affected by rotation, rising and falling.

[0021] (4) The novel opening method, which can cover or reveal the button by rotating and lifting the dust cover, can increase the product's appeal, enhance consumers' use and interest in the product, and make it convenient to use and carry. Attached Figure Description
