[0033] The utility model will be further described in detail below in combination with the drawings.

[0034] Figures 1-7 The schematic view shown is the embodiment, and the full plastic simple vacuum bottle in the embodiment mainly includes a bottle body 1, a shoulder sleeve 2, a pressing cap 3 and an elastic sleeve 4.

[0035] REFERENCE Figures 1 to 5As shown, in this embodiment, the bottle body 1 has an opening 1a at the top for containing contents, a shoulder sleeve 2 is arranged at the top opening 1a of the bottle body 1, the inside of the shoulder sleeve 2 is formed with a feeding channel 2a communicating with the inside of the bottle body 1, the outlet end of the feeding channel 2a is formed with a feeding hole 2a1 penetrating up and down, a pressing cap 3 can be lifted up and down under the action of external force, the inside of the pressing cap 3 is formed with a discharging channel 3a, and an elastic sleeve 4 is arranged between the shoulder sleeve 2 and the pressing cap 3 and is made of full plastic material and has elasticity, which is generally made of soft rubber material such as PE having elasticity, which is the key innovative component of the vacuum bottle.

[0036] The specific structure and function of the elastic sleeve 4 are as follows: the inside of the elastic sleeve 4 is formed with a storage area 4a, the upper and lower sides of the storage area 4a are respectively formed with a discharging port 4a1 and a feeding port 4a2, the discharging port 4a1 can communicate with the discharging channel 3a, and the feeding port 4a2 can communicate with the feeding channel 2a. The elastic sleeve 4 is also formed with a first sealing portion 4b and a second sealing portion 4c for one-way sealing of the feeding port 4a2 and the discharging port 4a1, respectively.

[0037] As shown in Figures 4 to 7 , the first sealing portion 4b here includes a plugging head 4b1 capable of sealing the feeding hole 2a1 from top to bottom, the plugging head 4b1 is integrally formed at the feeding port 4a2 of the elastic sleeve 4 and is arranged at the center of the feeding port 4a2, and an integrally formed elastic arm 4b2 is connected between the side of the plugging head 4b1 and the inner circumferential wall of the feeding port 4a2. The side of the plugging head 4b1 is also formed with a stepped surface 4b3, which can prevent the plugging head 4b1 from continuing to move downward after moving downward to a set position by limiting the outer edge of the feeding hole 2a1 through the stepped surface 4b3.

[0038] As shown in Figure 4 and Figure 5 , the second sealing portion 4c here includes a first annular wall 4c1 integrally formed at the discharging port 4a1 of the elastic sleeve 4 and extending upward, and a second annular wall 3b extending downward and located on the inner circumferential side of the first annular wall 4c1 is formed on the pressing cap 3. When the elastic sleeve 4 is compressed and shrinks, the first annular wall 4c1 deforms outward, the discharging port 4a1 is opened, and the contents are discharged through the discharging channel 3a; when the elastic sleeve 4 is released and rebounds, the first annular wall 4c1 resets inward and fits on the outer peripheral surface of the second annular wall 3b, closing the discharging port 4a1.

[0039] The installation and fitting structure of each component in this embodiment is as follows: A first mounting cavity 3c with a downward-facing opening and connected to the discharge channel 3a is formed on the pressing cap 3. A first mounting portion 4d is formed at the upper end of the elastic sleeve 4, which can be installed from bottom to top within the first mounting cavity 3c. This design makes the connection between the elastic sleeve 4 and the pressing cap 3 more stable. A second mounting portion 2b is formed on the shoulder sleeve 2, which can be installed within the inlet 4a2, ensuring a tight connection between the shoulder sleeve 2 and the elastic sleeve 4. Furthermore, a downward-extending limiting post 3d is formed on the pressing cap 3. When the pressing cap 3 is pressed down to the set position, the limiting post 3d can abut against the sealing head 4b1 from top to bottom, preventing the pressing cap 3 from continuing to move downward, thus protecting the internal structure.

[0040] The shoulder sleeve 2 also has a second mounting cavity 2c with an opening facing downward for the pressing cap 3 to enter at least partially from top to bottom. A first limiting surface 2d is formed on the inner circumferential surface of the second mounting cavity 2c, and a second limiting surface 3e that can fit the first limiting surface 2d is formed on the outer circumferential surface of the pressing cap 3. Through the mutual limiting of the two, the pressing cap 3 is restricted from moving upward to the set position and then continuing to move upward, thus ensuring the stability of the vacuum bottle during use.

[0041] Secondly, the shoulder sleeve 2 is connected to the bottle body 1 via a snap-fit ​​connection or a threaded connection, thus enabling a detachable connection. Figure 3 and Figure 4 The connection shown is a snap-fit ​​connection, which is installed and removed by inserting and pulling. The outer periphery of the shoulder sleeve 2 has a mounting wall 2e that extends downward and surrounds the outer edge of the opening 1a of the bottle body 1. The snap-fit ​​or internal thread can be set on the inner periphery of the mounting wall 2e. This connection method is convenient for installation and can ensure the sealing of the connection.

[0042] Furthermore, the storage area 4a of the elastic sleeve 4 also features a special design. Here, the storage area 4a of the elastic sleeve 4 has a bellows structure. This structure provides axial elastic deformation space, making the elastic sleeve 4 more flexible during compression and rebound, ensuring the normal operation of the vacuum bottle. When the pressing cap 3 is pressed down, the elastic sleeve 4 is squeezed downwards and contracts. The first sealing part 4b blocks the inlet 4a2, and the second sealing part 4c, after being compressed and deformed, separates from the outlet 4a1. The contents of the storage area 4a are discharged through the outlet channel 3a. When the external force is released, the elastic sleeve 4 returns to its original position and pushes the pressing cap 3 upwards. After the second sealing part 4c returns to its original position, it blocks the outlet 4a1. The first sealing part 4b separates from the inlet 4a2, and the storage area 4a, under negative pressure, draws in the contents of the bottle body 1 through the inlet 4a2. This cycle repeats, realizing the normal discharge function of the vacuum bottle.

[0043] It needs to be explained here that through the above specific examples, it can be seen that the full-plastic simple vacuum bottle in the embodiment aims to solve many problems existing in existing vacuum bottles, such as metal springs prone to corrosion and rust, inconvenient recycling, too many accessories, difficult assembly, and high cost, etc. By adopting a brand-new full-plastic structure design, especially the unique elastic sleeve design, the one-way sealing function is realized, without the need for additional one-way valves, reducing the number of accessories and reducing the manufacturing cost, with good market application prospects. There are many innovations in the structure design, compared with traditional vacuum bottles, it has obvious advantages, and its beneficial effects mainly reflect in the following aspects:

[0044] 1. Convenient recycling: the whole is made of full-plastic material, completely abandoning the metal springs and other metal parts prone to corrosion and rust, when recycling the product, there is no need to separately disassemble the metal parts for classification and treatment like traditional products, it can be directly recycled, greatly simplifying the recycling process, improving the recycling efficiency, and meeting the requirements of environmental protection concept and sustainable development.

[0045] 2. Reduce manufacturing cost: the elastic sleeve 4 structure is designed to realize one-way sealing function, replacing one or more one-way valves in traditional vacuum bottles, reducing the number of accessories, not only reducing the raw material procurement cost, but also in the production and assembly process, due to the reduction of accessories, the assembly process is simplified, the assembly time is shortened, further reducing the labor cost, effectively controlling the overall manufacturing cost.

[0046] 3. Improve the use performance and stability: the storage area 4a of the elastic sleeve 4 adopts a bellows structure, which can provide sufficient axial elastic deformation space. During the operation of the pressing cap 3, the elastic sleeve 4 is compressed and shrinks and rebounds smoothly, ensuring that the contents are stably and efficiently discharged and sucked, the limiting column 3d on the pressing cap 3 cooperates with the blocking head 4b1 of the first sealing part 4b, and the limiting surface on the shoulder sleeve 2 and the pressing cap 3 cooperates with each other, accurately limiting the up and down movement range of the pressing cap 3, effectively avoiding damage to the internal structure due to excessive pressing or excessive rebound, prolonging the service life of the vacuum bottle and improving the user experience.
