Technical Field

[0001] The utility model relates to a vacuum bottle with a replacement package, in particular to a rotary buckle type vacuum bottle with a replacement package. Background Art

[0002] A vacuum bottle refers to a container that can isolate gas from the outside temperature or isolate external bacteria. It is mainly composed of a cylindrical or ellipsoidal container and a piston placed at the bottom. Its working principle is to use the contraction force of the spring and prevent air from entering the bottle to create a vacuum state, and use atmospheric pressure to push the piston at the bottom of the bottle forward. In order to facilitate the reuse of structures such as outer bottles, some existing vacuum bottles use a replacement structure; such as the application number 202322905679.6 disclosed in the Chinese patent literature, the authorization announcement date 2024.07.02, and the utility model name "Replaceable Deformed Rotating Vacuum Bottle"; However, the replacement of the above-mentioned products and similar products and the loading and unloading of the inner bottle assembly are still relatively inconvenient, the structural design is relatively complex, and the production and assembly are relatively inconvenient. In particular, it is difficult to quickly replace the replacement and realize the loading and unloading of the inner bottle assembly through the integration of the shoulder sleeve and the outer bottle. Summary of the invention

[0003] In order to overcome the above shortcomings, the purpose of the utility model is to provide a rotary buckle type replacement vacuum bottle in the art, so as to solve the technical problem that the outer bottle and shoulder cover structure design of the existing similar products is poor, which makes it difficult to quickly replace the outer bottle and realize the loading and unloading of the inner bottle assembly by integrating the shoulder cover with the outer bottle. The purpose is achieved through the following technical solutions.

[0004] A rotary snap-on replacement vacuum bottle, wherein an inner bottle is arranged inside an outer bottle of the vacuum bottle, a piston is arranged in the inner cavity of the inner bottle, a bottom cover is arranged at the bottom of the inner bottle, an outer thread at the top of the inner bottle is connected to an inner thread at one end of a large circle, a vacuum pump core is arranged at the center hole at the connection between the two, and a valve stem of the vacuum pump core extends out of the other end of the large circle and is connected to a head cap; a shoulder sleeve is arranged at the outer diameter of the connection between the bottle mouth of the outer bottle and the large circle, and the shoulder sleeve is connected to the bottle mouth of the outer bottle as a whole through a snap. The key points of its structural design are that the shoulder at the bottle mouth of the outer bottle is symmetrically provided with a special-shaped card slot, and the special-shaped card slot is connected to the opening introduced at the bottle mouth of the outer bottle in sequence with the communicating oblique opening and the communicating horizontal opening as a whole; buckle points are symmetrically arranged on both sides of the outer diameter of the large circle corresponding to the special-shaped card slot, and the bottle mouth of the outer bottle and the large circle are aligned through the buckle points of the large circle and screwed into the special-shaped card slot of the outer bottle for connection. The replacement package of the above-mentioned vacuum bottle is another combination of an inner bottle, a bottom cover, and a piston. The bottle mouth of the assembled inner bottle is provided with a sealing film and a replacement cover. Alternatively, another group of inner bottle, bottom cover, piston, and vacuum pump core, large ring, and head cap are further combined to form a replacement package. Open the outer bottle, remove the original inner bottle and its bottom cover and piston, install a new inner bottle of the replacement package, and then re-install the outer bottle. The replacement package can be used.

[0005] At the bottom of the socket at the shoulder of the outer bottle, there is a rotating rib for mating with the shoulder sleeve, and the rotating rib of the outer bottle is engaged with the rotating groove at the inner diameter of the bottom of the shoulder sleeve. Thus, the shoulder sleeve is fixed to the outer bottle as a whole and is not easily lost.

[0006] At the outer diameter of the socket at the shoulder of the outer bottle, there is a positioning rib. When the rotating rib of the outer bottle is engaged with the rotating groove of the shoulder sleeve, the positioning rib of the outer bottle is correspondingly inserted into the positioning groove at the inner diameter of the shoulder sleeve and is integrated.

[0007] At the inner diameter of the shoulder sleeve, there is a feel groove, and there are feel ribs in the feel groove. When the positioning rib of the outer bottle is correspondingly inserted into the positioning groove at the inner diameter of the shoulder sleeve and is integrated, the feel groove and the feel ribs of the shoulder sleeve are located outside the special-shaped card slot of the outer bottle. When the buckle point of the large circle rotates through the special-shaped card slot of the outer bottle, the buckle point of the large circle abuts against the feel rib. Thus, a damping feeling or a collision sound is generated by the abutment of the buckle point of the large circle and the feel rib.

[0008] The outer diameter of the buckle point at the bottom of the large circle is aligned with the outer diameter of the inner bottle to form a cylinder. Thus, it is convenient to install the replacement set composed of the above-mentioned inner bottle, bottom cover, piston, vacuum pump core, large circle, and head cap into the shoulder sleeve and the outer bottle.

[0009] The structure of the utility model is reasonably designed, convenient for assembly production, with low production cost, especially convenient for replacing the replacement set; it is suitable for use as a rotary snap-on replacement vacuum bottle and the structural improvement of its similar products.
