Description

Technical Field

[0001] This utility model relates to the field of cosmetic containers, and in particular to a vacuum bottle with an easily replaceable inner liner. Background Technology

[0002] Vacuum bottles are primarily used as containers for beauty, cosmetic, and skincare products. The contents of vacuum bottles are typically liquids, emulsions, creams, or pastes. Vacuum bottles completely isolate the contents from air, preventing oxidation, spoilage, and bacterial growth. Currently, existing vacuum bottles, such as the Chinese utility model patent application CN202322443169.1 (authorization announcement number CN220702019U) titled "High-Sealing Press-Down Vacuum Bottle," include a bottle body, an inner liner, a shoulder sleeve, a connecting cap, and a press cap. The inner liner is installed inside the bottle body, the shoulder sleeve is mounted on the connecting cap, and the connecting cap is mounted on the bottle body. A pump core is located in the connecting cap. The press cap is movably connected to the shoulder sleeve and has a discharge channel inside. Users can remove the contents of the inner liner by pressing the press cap and using the pump core.

[0003] Although the contents of the aforementioned vacuum bottle can be removed by pressing, it can only be discarded after use; the inner liner cannot be replaced, making it a disposable item and resulting in resource waste. Therefore, the vacuum bottle is neither economical nor environmentally friendly. Further improvements to the vacuum bottle are needed. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a vacuum bottle with a reasonable structure and easy replacement of the inner liner, in view of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the vacuum bottle with a conveniently replaceable inner liner includes a bottle body, characterized in that: the bottle body is divided into a top cover, an upper bottle body and a lower bottle body from top to bottom; the upper end of the upper bottle body has a discharge port; rotating the top cover can cover or open the discharge port of the upper bottle body; the upper bottle body has an installation cavity for a portion of the lower bottle body to be inserted from below; the peripheral wall of the installation cavity is provided with an internal thread; the outer peripheral wall of the lower bottle body is provided with an external thread that mates with the internal thread; and the lower bottle body is provided with an inner liner that can be detachably connected to it; when the lower bottle body is inserted into the installation cavity, the lower bottle body can be threadedly connected to the upper bottle body, so that the inner liner inside the lower bottle body can communicate with the discharge port.

[0006] Furthermore, the upper bottle body is equipped with a pressing assembly, which includes a pressing cap with a dispensing port. The pressing cap protrudes from the upper end of the upper bottle body and can move vertically relative to the upper bottle body. The lower end of the top cap has a groove for inserting the pressing cap. The user can press the pressing cap to squeeze the contents of the inner liner out from the dispensing port, and the groove of the top cap allows the pressing cap to be inserted, so that the top cap can be placed on the upper bottle body to cover the dispensing port of the pressing cap.

[0007] Furthermore, the top cover has multiple spaced upper magnets around the periphery of the groove, and the upper bottle body has multiple lower magnets corresponding to the upper magnets around the periphery of the cap. When the top cover is placed on the upper bottle body and rotated, each upper magnet is attracted to its corresponding lower magnet, and the top cover can cover the discharge port of the upper bottle body. Rotating the top cover can also open the top cover to expose the discharge port of the upper bottle body by displacing the upper and lower magnets. The top cover of this vacuum bottle is attached to or displaced by the upper and lower magnets, allowing it to be placed on or removed from the upper bottle body. This design simplifies the connection between the top cover and the upper bottle body.

[0008] Furthermore, it also includes an annular connector, which is mounted on the outer peripheral wall of the pressing assembly and also engages with the inner peripheral wall of the upper bottle body, thereby allowing the pressing assembly to be positioned within the upper bottle body via the annular connector. This annular connector design allows the pressing assembly to be positioned within the upper bottle body, resulting in a more rational structure for the vacuum bottle and facilitating its production and assembly.

[0009] Furthermore, the annular connector is provided with multiple fixing slots corresponding to the upper magnets, and each lower magnet is installed in the corresponding fixing slot. The annular connector also has the function of installing the lower magnets, so that the top cover is attracted to the annular connector. Since the annular connector is engaged with the upper bottle body, the top cover can cover or open the discharge port of the upper bottle body.

[0010] Furthermore, the outer peripheral wall of the annular connector is provided with multiple elastic buckles, and the inner peripheral wall of the upper bottle body is provided with grooves corresponding to the elastic buckles. The elastic buckles engage with the corresponding grooves, allowing the annular connector to be installed inside the upper bottle body. This configuration enables the annular connector to engage with and be installed inside the upper bottle body.

[0011] Furthermore, the pressing assembly includes a mounting portion for connection with the annular connector. The internal thread is provided on the inner peripheral wall of the mounting portion. The outer peripheral wall of the mounting portion has multiple circumferentially extending and outwardly protruding protrusions. The inner peripheral wall of the annular connector has a circumferentially extending and inwardly protruding step. The inner diameter of the step is smaller than the outer diameter of the protrusion. The step abuts against the lower end of the protrusion. The periphery of the pressing cover abuts against the upper end of the annular connector, thus allowing the annular connector to be mounted on the outer peripheral wall of the pressing assembly. The engagement between the pressing cover and the annular connector prevents the pressing assembly from detaching from the upper end of the annular connector; the engagement between the step and the protrusions prevents the pressing assembly from detaching from the lower end of the annular connector, thereby ensuring the pressing assembly is installed within the annular connector.

[0012] Furthermore, the outer peripheral wall of the mounting part is provided with multiple vertically extending sliders, and the inner peripheral wall of the annular connector is provided with multiple grooves corresponding to the sliders. The sliders are located within the grooves to prevent the pressing component from rotating relative to the annular connector. Through the cooperation of the sliders and grooves, the pressing component is prevented from rotating around its own central axis relative to the annular connector, ensuring the stability of the connection between the pressing component and the annular connector.

[0013] Furthermore, the lower bottle body has an inner cavity for inserting the inner liner, which can be dislodged from the inner cavity under an upward force. The inner cavity of the lower bottle body allows for the insertion and placement of the inner liner, and the lower bottle body and the inner liner are detachably connected by insertion and removal, facilitating the replacement of the inner liner.

[0014] Furthermore, the upper periphery of the inner liner is provided with two downwardly extending inserts, which are arranged opposite each other. The outer peripheral wall of the lower bottle body is provided with two slots corresponding to the inserts, which allow the corresponding inserts to be inserted or removed. The two slots are located between external threads. This arrangement of inserts and slots facilitates the insertion and removal of the inner liner from the inner cavity, making it convenient for the user to replace the inner liner.

[0015] Compared with the prior art, the advantages of this utility model are as follows: The vacuum bottle is divided into three parts from top to bottom: a top cover, an upper bottle body, and a lower bottle body. The top cover can be detachably connected to the upper bottle body by rotating it, allowing the discharge port of the upper bottle body to be covered or exposed, thus preventing accidental contact and squeezing of the contents when the vacuum bottle is not in use. Furthermore, the upper and lower bottle bodies are threadedly connected, making them detachable as well. When the inner liner needs to be replaced, the upper or lower bottle body is rotated to separate them, and the inner liner located in the lower bottle body is pulled out for replacement. The replaced inner liner is then inserted into the lower bottle body, and the upper and lower bottle bodies are threadedly reconnected to complete the assembly of the vacuum bottle. Therefore, this vacuum bottle has a reasonable structure and facilitates inner liner replacement, making the vacuum bottle reusable. Users only need to replace the inner liner, thus effectively improving the environmental friendliness and economy of the vacuum bottle. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-7 The figure shown is the preferred embodiment of this utility model.

[0025] like Figures 1-3 as well as Figure 7 As shown, the vacuum bottle in this embodiment includes a bottle body, which is divided into a top cover 1, an upper bottle body 2 and a lower bottle body 3 from top to bottom. The upper bottle body 2 is provided with a pressing component 5, which includes a pressing cover 51 with a discharge port 511. The pressing cover 51 is exposed at the upper end of the upper bottle body 2 and can move vertically relative to the upper bottle body 2. The lower end of the top cover 1 is provided with a groove 11 for the pressing cover 51 to be inserted. When the top cover 1 is placed on the upper bottle body 2, the pressing cover 51 is located in the groove 11. Furthermore, the top cover 1 has multiple spaced upper magnets 6 around the groove 11, and the upper bottle body 2 has multiple lower magnets 7 corresponding to the upper magnets 6 around the cover 51. The top cover 1 is placed on the upper bottle body 2 and rotated so that each upper magnet 6 is attracted to the corresponding lower magnet 7, and the top cover 1 can cover the discharge port 511 of the upper bottle body 2. Rotating the top cover 1 makes the upper magnets 6 and lower magnets 7 staggered, and the top cover 1 can be opened to expose the discharge port 511 of the upper bottle body 2.

[0026] like Figure 2 and Figure 4As shown, the upper bottle body 2 of this embodiment has an installation cavity 21 for inserting part of the lower bottle body 3 from below. The peripheral wall of the installation cavity 21 is provided with an internal thread 53, and the outer peripheral wall of the lower bottle body 3 is provided with an external thread 31 that mates with the internal thread 53. The lower bottle body 3 is provided with an inner liner 4 that can be detachably connected to it. When the lower bottle body 3 is inserted into the installation cavity 21, the lower bottle body 3 can be threadedly connected to the upper bottle body 2, so that the inner liner 4 inside the lower bottle body 3 can communicate with the discharge port 511. The user can squeeze the contents of the inner liner 4 out of the discharge port 511 by pressing the cap 51. In this embodiment, the lower bottle body 3 is provided with an inner cavity 32 for inserting the inner liner 4. The inner liner 4 can be dislodged from the inner cavity 32 under an upward force. That is, the inner liner 4 and the lower bottle body 3 are detachably connected by insertion and removal. Specifically, the upper periphery of the inner liner 4 is provided with two downwardly extending inserts 41, which are arranged opposite to each other. The outer peripheral wall of the lower bottle body 3 is provided with two slots 33 corresponding to the inserts 41. The slots 33 allow the corresponding inserts 41 to be inserted or removed. The two slots 33 are arranged between the external threads 31. Through the cooperation of the inserts 41 and the slots 33, the inner liner 4 can be smoothly installed into or removed from the inner cavity 32.

[0027] like Figures 5-7As shown, the bottle body in this embodiment also includes an annular connector 8. The annular connector 8 is installed on the outer peripheral wall of the pressing assembly 5, and the annular connector 8 is also engaged with the inner peripheral wall of the upper bottle body 2, thereby allowing the pressing assembly 5 to be positioned inside the upper bottle body 2 by means of the annular connector 8. The annular connector 8 has multiple fixing grooves 81 corresponding to the upper magnet 6, and each lower magnet 7 is installed in the corresponding fixing groove 81, allowing the top cover 1 to cover or open the discharge port 511 of the upper bottle body 2 by means of the annular connector 8. Furthermore, the outer peripheral wall of the annular connector 8 in this embodiment has multiple elastic buckles 82, and the inner peripheral wall of the upper bottle body 2 has grooves 22 corresponding to the elastic buckles 82. The elastic buckles 82 engage with the corresponding grooves 22, allowing the annular connector 8 to be installed inside the upper bottle body 2. In addition, the pressing assembly 5 of this embodiment also includes a mounting part 52 for connecting with the annular connector 8. An internal thread 53 is provided on the inner peripheral wall of the mounting part 52. The outer peripheral wall of the mounting part 52 is provided with a plurality of protrusions 521 extending circumferentially and protruding outward. The inner peripheral wall of the annular connector 8 is provided with a step 83 extending circumferentially and protruding inward. The inner diameter of the step 83 is smaller than the outer diameter of the protrusion 521. The step 83 can abut against the lower end of the protrusion 521. The periphery of the pressing cover 51 can abut against the upper end of the annular connector 8, so that the annular connector 8 is installed on the outer peripheral wall of the pressing assembly 5. That is, by the cooperation between the pressing cover 51 and the upper end of the annular connector 8, the pressing assembly 5 is prevented from coming off the upper end of the annular connector 8. By the cooperation between the step 83 and the protrusion 521, the pressing assembly 5 is prevented from coming off the lower end of the annular connector 8. Furthermore, the outer peripheral wall of the mounting part 52 in this embodiment is provided with a plurality of vertically extending sliders 522, and the inner peripheral wall of the annular connector 8 is provided with a plurality of grooves 84 corresponding to the sliders 522. The sliders 522 are located in the grooves 84 to prevent the pressing component 5 from rotating relative to the annular connector 8.

[0028] The workflow of this embodiment is as follows: When the vacuum bottle needs to have its inner liner 4 replaced, first hold and rotate the upper bottle body 2 or the lower bottle body 3 to separate the upper bottle body 2 from the lower bottle body 3, that is, the lower bottle body 3 is removed from the mounting cavity 21 of the upper bottle body 2; the user then presses down on the two inserts 41 and applies an upward force to make the inner liner 4 come out of the inner cavity 32 of the lower bottle body 3, thereby replacing the new inner liner 4; then the user tears open the sealing film on the new inner liner 4 and inserts it into the inner cavity 32 of the lower bottle body 3; finally, the lower bottle body 3 is inserted into the mounting cavity 21 of the upper bottle body 2 and rotated to make the upper bottle body 2 and the lower bottle body 3 threadedly connected, thereby completing the replacement of the inner liner 4 of the vacuum bottle.
