Description

Technical Field

[0001] The utility model relates to the technical field of vacuum bottles, in particular to a vacuum bottle made of glass material. Background Art

[0002] Vacuum bottles are mainly used as containers for beauty, makeup, and skin care products, and the internal fillers are liquid, milky, creamy, or paste-like substances. As Figure 1 shown, it is a cross-sectional view of a vacuum bottle in the prior art. Its structure includes a transparent outer bottle, a shoulder sleeve, and a transparent outer cover sleeved on the outside of the shoulder sleeve... A communication hole is symmetrically opened inside the bottom plate of the vacuum bottle. The communication holes are respectively located at the bottom surfaces of Vacuum Bottle One, Vacuum Bottle Two, and Vacuum Bottle Three. The communication holes are located below the piston of the vacuum bottle. An inner ventilation hole is opened at the bottom of the transparent outer bottle. The communication hole is communicated with the inner ventilation hole... For a vacuum bottle with such a structure, an inner ventilation hole must be opened on the outer bottle, and only with this inner ventilation hole can the piston be pushed to discharge materials by using the air pressure difference. However, if the inner ventilation hole is set on a glass bottle, a relatively complex process is required, and the production is rather cumbersome. There may be a situation of breakage during the production process. Summary of the Utility Model

The middle section 2 is detachably installed on the outer bottle 1, the locking cap 3 is installed inside the middle section 2, the inner liner 4 is detachably installed on the locking cap 3, the pump core 5 is installed on the locking cap 3, and the head cap 6 is installed on the pump core 5. The inner wall of the outer bottle 1 does not fit against the outer wall of the inner liner 4, and a gas storage cavity 7 is formed between the outer bottle 1 and the inner liner 4. A piston 8 is arranged inside the inner liner 4, and the outer wall of the piston 8 fits tightly against the inner wall of the inner liner 4. A bottom plate 9 is arranged at the bottom of the inner liner 4, and a communication hole (not shown in the figure) penetrating the bottom plate 9 is arranged on the bottom plate 9. The communication hole serves to connect the gas storage cavity 7 and the inner liner 4. Specifically, air is stored in the gas storage cavity 7, and the amount of gas stored inside the gas storage cavity 7 is greater than the amount required to push the piston 8 from the bottom of the inner liner 4 to the top, that is, the amount of gas stored inside the gas storage cavity 7 can take out all the materials stored in the inner liner 4.

[0028] A clamping platform 10 and a convex buckle 11 are arranged inside the middle section 2. The clamping platform 10 is located above the convex buckle 11. The locking cap 3 is installed between the clamping platform 10 and the convex buckle 11. The cooperation of the clamping platform 10 and the convex buckle 11 restricts the locking cap 3 in the axial direction. A number of vertically distributed limiting ribs 12 are also arranged inside the middle section 2, and a number of vertically distributed limiting grooves 13 are arranged on the outer side of the locking cap 3. The limiting ribs 12 are inserted into the limiting grooves 13. The cooperation of the limiting ribs 12 and the limiting grooves 13 restricts the locking cap 3 in the circumferential direction. That is, under the combined action of the cooperation of the clamping platform 10, the convex buckle 11 and the cooperation of the limiting ribs 12 and the limiting grooves 13, the locking cap 3 can be fixedly installed in the middle section 2.

[0029] A first clamping convex 14 is arranged on the inner wall of the locking cap 3, and a first clamping groove 15 is arranged on the pump core 5. The pump core 5 is fixed in the locking cap 3 through the clamping cooperation of the first clamping convex 14 and the first clamping groove 15.

[0033] The present utility model is a vacuum bottle made of glass material, and its working principle is described in combination with the attached drawings:

[0034] There is no internal ventilation hole on the outer bottle 1 of the utility model, and air is stored in the air storage cavity 7. When it is necessary to pump materials, press the head cap 6. Pumping will extract some gas from the inner liner 4 to form a pressure difference. The air in the air storage cavity 7 will enter the bottom of the inner liner 4 through the communication hole, thereby pushing the piston 8 to rise for discharging materials. If the air stored in the air storage cavity 7 is insufficient, the middle section 2 can be unscrewed, and external air will be poured into the air storage cavity 7 again.

[0035] When the materials in the inner liner 4 are used up, only need to first rotate and unscrew the middle section 2, take out the middle section 2, the lock cover 3, the inner liner 4, the pump core 5 and the head cap 6, then rotate and unscrew the inner liner 4, disassemble the inner liner 4, reassemble a new inner liner 4, put it back into the outer bottle 1 and tighten the middle section 2 to complete the replacement of the inner liner 4.

[0036] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection claimed by the utility model is defined by the appended claims and their equivalents.
