Description

TECHNICAL FIELD

[0001] The utility model relates to a vacuum bottle, and is a rotary paste vacuum bottle. BACKGROUND

[0002] A vacuum bottle refers to a container that can isolate gas from the outside temperature or a container that can isolate external bacteria. The vacuum bottles sold on the market are composed of an elliptical container with a cylindrical body and a piston placed at the bottom. The working principle is mainly to use the contraction force of the spring, prevent air from entering the bottle, and create a vacuum state, and use atmospheric pressure to push the piston at the bottom forward. A cream bottle is a container for storing and accessing cream and other pastes. The structure is relatively simple, and the cream can be accessed after the bottle cap and gasket are opened. This type of cream is a skin care emulsified product. According to the oil content, there are cream, neutral cream (moisturizing cream), and balm. According to the emulsifier type, there are oil-in-water and complex emulsion. Some cream bottles use vacuum bottle structures, such as the patent document CN115158873A, published on October 11, 2022, with the invention name "pressure-resistant high-molecular rotary lock buckle pressing vacuum cream bottle and preparation method thereof". Some vacuum bottles are equipped with screw structures, such as the patent document CN212345693U, published on January 15, 2021, with the utility model name "lightweight anti-static vacuum bottle".

[0020] The structure of this utility model will now be further described with reference to the accompanying drawings. For example... Figures 1-5 In the first embodiment shown, the vacuum bottle containing the ointment is cylindrical, with a screw inside. The ointment inside the bottle is extruded through the top hole 601 in the center of the cap 6 by rotating the screw, which drives a piston to move up and down. The bottle body includes an inner bottle 3 and an outer bottle 1. The inner wall of the outer bottle has a positioning groove 101 at the bottle mouth, and a second positioning rib 501 is provided on the outer diameter of one end of the large ring 5 corresponding to the positioning groove. The inner wall of the bottom of the outer bottle has a raised rib 102, and the bottom of the inner bottle corresponding to the raised rib has a raised collision rib 301. The outer diameter of the inner bottle has a raised buckle ring 302. The inner wall of the top of the cap has a buckle groove 602, and the inner wall of the cap has a toothed ring 603. The positioning groove of the outer bottle is inserted into... Simultaneously, the second positioning rib of the large ring is engaged with the positioning groove of the outer bottle and the second positioning rib of the large ring, forming a single unit. The first positioning rib 303, extending from the outer diameter of the inner bottle section of the large ring, is inserted into one side of the toothed groove ring on the inner wall of the cap. The buckle of the cap is engaged and fixed to the buckle ring of the large ring. The collision rib of the inner bottle is aligned with the convex rib of the outer bottle. The inner diameter of the convex rib of the outer bottle is larger than the outer diameter of the collision rib of the inner bottle. The bottom of one end of the screw is fitted into the central column protruding in the middle of the bottom of the outer bottle.

[0021] The aforementioned screw is the first screw 2, and the piston is the piston sleeve 4. The other end of the first screw extends into the inner bottle through the center of the bottom of the inner bottle. Simultaneously, the first screw is internally threaded into the center hole of the piston sleeve in the inner bottle. The arc-shaped grooves 401 evenly spaced on the outer diameter of the piston sleeve engage with the arc-shaped ribs 304 evenly spaced on the inner wall of the inner bottle. A raised sealing leaf 402 is located in the middle of the outer diameter of the piston sleeve, abutting against the inner wall of the inner bottle for sealing. One end of the first screw at the bottom of the outer bottle has an end edge. This end edge fits into the side groove at the bottom of the outer bottle, and is confined to the raised base platform at the bottom of the inner bottle. Symmetrical collision ribs of the inner bottle are symmetrically raised on both sides of the ring surface below the raised base platform at the bottom of the inner bottle, with the outer diameter of the ring surface protruding higher than the outer diameter of the inner bottle. Meanwhile, the inner bottle has a first bamboo joint rib 305 and a second bamboo joint rib 306 that are equidistantly arranged between the two ends of the outer diameter. The diameter of the second bamboo joint rib below the first bamboo joint rib is larger than the diameter of the first bamboo joint rib. The second bamboo joint rib is limited to the limiting groove 502 at the bottom inner diameter opening of the large ring.

[0022] The cap is provided with an outer cover 7 on the outside, and the opening of the outer cover is fastened and fixed to the outer diameter of the large circle extending out of the outer bottle; the top of the outer cover is provided with a protruding stopper 701, which is inserted into the top hole of the cap with an interference seal, and the top hole of the cap is arc-shaped protrusion.

[0023] To use, open the outer cover, hold the outer bottle with one fingertip and the cap with the other fingertip, and rotate them in opposite directions to squeeze the ointment out of the top hole of the cap; rotate the cap in the opposite direction to collect the ointment into the inner bottle.

[0024] Based on the above structural characteristics, such as Figure 6 In the second embodiment shown, the screw is a second screw 8, and the piston is a large piston 9. The other end of the second screw is integrated with the bottom of the large piston in the inner bottle. Simultaneously, the second screw is internally threaded into the central screw hole of the screw seat 11 in the inner bottle. The bottom of the screw seat is fastened and fixed to the bottom of the outer bottle and integrated with it. A sealing sleeve 10 is fixedly provided on the top outer diameter of the connection between the second screw and the screw seat. The outer diameter of the large piston abuts against the inner wall of the inner bottle for sealing. The sealing sleeve on the outer diameter of the screw seat below the large piston abuts against the inner wall of the inner cap. Although the height of the second embodiment is greater than that of the first embodiment, and it includes a sealing sleeve and a screw seat, improving the piston and screw structure, it still achieves the same technical purpose and effect. In the first embodiment, the first screw does not move up and down; the rotation of the outer bottle and cap causes the piston sleeve to move up and down on the first screw. In the second embodiment, the second screw and the large piston move up and down together; the rotation of the outer bottle and cap causes the screw seat to rotate together, and the second screw moves up and down on the screw seat.
