Description
Technical Field
[0001] This utility model relates to a vacuum bottle, and more specifically, to a vacuum bottle with good sealing performance. Background Technology
[0002] A vacuum bottle is a container that isolates gas from external temperatures or bacteria. The contents of a vacuum bottle are completely isolated from air, preventing oxidation, spoilage, and bacterial growth caused by air contact, and enhancing the product's perceived value through its high-tech concept. Commonly available vacuum bottles consist of a cylindrical or elliptical container with a piston at the bottom. Its design principle uses the contraction of a spring to create a vacuum, preventing air from entering the bottle, while atmospheric pressure propels the piston forward.
[0003] Chinese Patent Announcement CN215603744U discloses a vacuum cream bottle for cosmetics. Its key technical features include: a bottle body, an inner liner, a piston, a shoulder sleeve, a top cover, a middle layer component, a one-way assembly, a push cap, and a sealing cap. The inner liner is fixedly installed inside the bottle body, and the piston is movably installed inside the inner liner. A shoulder sleeve is fixedly installed outside the bottle body and the inner liner. A top cover is fixedly installed inside the shoulder sleeve. A middle layer component is fixedly installed inside the top cover. A lower cover plate is fixedly installed at the bottom of the middle layer component. A one-way assembly is embedded at the top of both the top cover and the middle layer component. A push cap is fixedly installed at the top of the top cover. A sealing cap is threaded onto the outside of the shoulder sleeve. A material guide groove is formed at the top of the middle layer component.
[0004] The sealing plug in the above-mentioned technical solution will have poor resilience after repeated deformation, making it prone to fatigue failure and resulting in an incomplete seal. Once the seal fails, air may enter the bottle, causing oxidation, spoilage, or bacterial growth of the contents.
[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vacuum bottle with good sealing performance.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vacuum bottle with good sealing performance, characterized in that: it includes a vacuum bottle body, a protective cover is provided on the vacuum bottle body, a skeleton is provided inside the protective cover, a silicone body is provided on the skeleton, a connecting body is provided at the bottom of the silicone body, an annular groove is provided on the connecting body, an annular protrusion is provided at the top of the vacuum bottle body, two first positioning rings are also provided on the outer circumference of the silicone body, each of the two first positioning rings is provided with a plurality of positioning holes, a second positioning ring is provided on the inner wall of the skeleton, a plurality of positioning pins inserted into the positioning holes are provided at the top and bottom of the second positioning ring, and the two first positioning rings respectively abut against the top and bottom of the second positioning ring.
[0008] By adopting the above technical solution, the annular protrusion on the vacuum bottle body and the annular groove on the connecting body are mutually positioned, enabling the silicone body to be accurately positioned and installed on the vacuum bottle body. The silicone body and the skeleton are connected through the positioning hole of the first positioning ring and the positioning post of the second positioning ring. During the insertion process, when the silicone body is about to deform, the skeleton plays a fixing role. At the same time, the connecting body of the silicone body and the first positioning ring at the bottom exert a pulling force to prevent deformation. As the protective cover rotates, the connecting body and the first positioning ring at the bottom are relatively fixed under the action of the skeleton and the vacuum bottle body. Therefore, when the first positioning ring at the top and the top of the silicone body are affected by the insertion force, the toughness of the connecting body and the first positioning ring at the bottom prevents the silicone body from deforming as a whole, ensuring that the seal is not damaged during use.
[0009] The present invention is further configured such that: a plurality of first positioning protrusions are provided on the outer circumference of the vacuum bottle body, and each of the first positioning protrusions is provided with an anti-disengagement buckle; and the vacuum bottle body is also provided with a threaded protrusion.
[0010] The present invention is further configured such that: a plurality of second positioning protrusions are provided on the inner wall of the protective cover, the second positioning protrusions abut against the first positioning protrusion and the anti-disengagement buckle; a threaded groove is provided on the inner wall of the protective cover, and a positioning eave is fixedly connected to the bottom of the threaded groove, the positioning eave abutting against the threaded protrusion.
[0011] The present invention is further configured such that: a plurality of third positioning protrusions are provided on the inner wall of the protective cover, and extension rings are provided at the bottom and top of the frame, with two of the extension rings abutting against the third positioning protrusions.
[0012] The present invention is further configured such that: an installation ring is provided on the body of the vacuum bottle, and the installation ring abuts against the bottom of the protective cover.
[0013] The present invention is further configured such that: the outer circumference of the protective cover is provided with several chamfered grooves.
[0014] The present invention has the following beneficial effects: 1. The positioning is achieved by the annular protrusion of the vacuum bottle body and the annular groove of the silicone body connector, the positioning hole of the first positioning ring is connected to the positioning post of the second positioning ring, and the protective cover abuts against the skeleton, so that the silicone body, the skeleton and the vacuum bottle body are tightly connected, thereby enhancing the overall stability.
[0015] 2. When inserting the pin, the skeleton fixes the silicone body, and the connector and the first positioning ring at the bottom are pulled to prevent deformation, ensuring that the seal is not damaged during use.
[0016] 3. The first positioning protrusion, anti-disengagement buckle, and threaded protrusion of the vacuum bottle body cooperate with the second positioning protrusion, threaded groove, and positioning eave of the protective cover to ensure that the protective cover will not open accidentally when subjected to force in different directions, thus ensuring high reliability.
[0017] 4. The third positioning protrusion on the inner wall of the protective cover abuts against the extension ring on the skeleton to form a stable connection structure, preventing relative displacement of the skeleton inside the protective cover, avoiding affecting the performance of the vacuum bottle, and also assisting in sealing.
[0018] 5. The chamfered groove on the outer circumference of the protective cap makes it easy to pick up the entire vacuum bottle with your fingers. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.
[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0026] like Figures 1 to 3 As shown, a vacuum bottle with good sealing performance includes a vacuum bottle body 1, a protective cover 2 on the vacuum bottle body 1, a frame 3 inside the protective cover 2, a silicone body 4 on the frame 3, a connector 5 at the bottom of the silicone body 4, an annular groove 6 on the connector 5, an annular protrusion 7 at the top of the vacuum bottle body 1, two first positioning rings 8 on the outer circumference of the silicone body 4, each of the two first positioning rings 8 having several positioning holes 9, a second positioning ring 10 on the inner wall of the frame 3, and several positioning pins 11 inserted into the positioning holes 9 at the top and bottom of the second positioning ring 10, with the two first positioning rings 8 respectively abutting against the top and bottom of the second positioning ring 10.
[0027] In use, the silicone body 4 is placed on top of the vacuum bottle body 1. The silicone body 4 is precisely positioned and installed on the vacuum bottle body 1 by the annular protrusion 7 on the vacuum bottle body 1 and the annular groove 6 on the connecting body 5. Then, the silicone body 4 and the frame 3 are connected by the positioning hole 9 of the first positioning ring 8 and the positioning post 11 of the second positioning ring 10. Finally, the protective cover 2 is rotated to install it onto the vacuum bottle body 1. The protective cover 2 can also abut against the frame 3, establishing a connection between the frame 3 and the vacuum bottle body 1, further enhancing the overall structure. For stability, during the insertion process, when the silicone body 4 is about to deform, the skeleton 3 plays a fixing role. At the same time, the connecting body 5 and the first positioning ring at the bottom of the silicone body 4 exert a pulling force to prevent deformation. As the protective cover 2 rotates, the connecting body 5 and the first positioning ring at the bottom are relatively fixed under the action of the skeleton 3 and the vacuum bottle body 1. Therefore, when the first positioning ring at the top and the top of the silicone body 4 are affected by the insertion force, the toughness of the connecting body 5 and the first positioning ring at the bottom prevents the silicone body 4 from deforming as a whole, ensuring that the seal is not damaged during use.
[0028] like Figures 2 to 4As shown, the outer circumference of the vacuum bottle body 1 is provided with several first positioning protrusions 12, and each of the first positioning protrusions 12 is provided with an anti-disengagement buckle 13. The vacuum bottle body 1 is also provided with a threaded protrusion 14. The inner wall of the protective cover 2 is provided with several second positioning protrusions 15, which abut against the first positioning protrusions 12 and the anti-disengagement buckle 13. The inner wall of the protective cover 2 is provided with a threaded groove 16, and the bottom of the threaded groove 16 is fixedly connected to a positioning eave 17, which abuts against the threaded protrusion 14.
[0029] During the installation of the protective cover 2 onto the vacuum bottle body 1, the protective cover 2 is rotated. The threaded groove 16 and positioning eaves 17 on the protective cover 2 pass through the first positioning protrusion 12 and anti-disengagement buckle 13 on the vacuum bottle body 1. As the rotation continues, the threaded protrusion 14 on the vacuum bottle body 1 abuts against the threaded groove 16 and positioning eaves 17 on the anti-slip surface. At the same time, the second positioning protrusion 15 on the protective cover 2 abuts against the first positioning protrusion 12 and anti-disengagement buckle 13 on the vacuum bottle body 1, thus completing the connection between the protective cover 2 and the vacuum bottle body 1. Through the cooperation of the first positioning protrusion 12, anti-disengagement buckle 13 and the second positioning protrusion 15, as well as the cooperation of the threaded protrusion 14 with the threaded groove 16 and positioning eaves 17, the protective cover 2 is ensured not to open accidentally when subjected to external forces such as axial pull or radial rotation.
[0030] like Figure 3 As shown, the inner wall of the protective cover 2 is also provided with several third positioning protrusions 18, and the bottom and top of the frame 3 are provided with extension rings 19, and the two extension rings 19 abut against the third positioning protrusions 18.
[0031] During the connection between the protective cover 2 and the vacuum bottle body 1, the third positioning protrusion 18 and the two extension rings 19 simultaneously abut against each other, so that a stable connection structure is formed between the protective cover 2 and the frame 3. When subjected to external force, it can prevent the frame 3 from being relatively displaced within the protective cover 2, and avoid affecting the performance of the vacuum bottle due to loose parts. The third positioning protrusion 18 and the extension rings 19 can also play a role in auxiliary sealing to a certain extent.
[0032] like Figure 1 As shown, a mounting ring 20 is provided on the vacuum bottle body 1, and the mounting ring 20 abuts against the bottom of the protective cover 2; the mounting ring 20 of the vacuum bottle body 1 provides corresponding support for the installation of the protective cover 2.
[0033] like Figures 1 to 3 As shown, the outer circumference of the protective cover 2 is provided with several chamfered grooves 21; the chamfered grooves 21 make it easy for fingers to pick up the entire vacuum bottle.
[0034] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
