Description

Technical Field

[0001] This utility model relates to the field of vacuum bottle technology, and in particular to a vacuum bottle based on an antistatic polymer material with a bottomless, square, strong-lock structure. Background Technology

[0002] A vacuum bottle is a container with a high degree of isolation from the internal and external environments. Its core principle lies in blocking heat conduction, air contact, and microbial growth through a vacuum state. Vacuum bottles can be used in thermos flasks, cosmetic packaging, and food and medicine preservation, among other applications.

[0003] In the prior art, vacuum bottles used to hold cosmetics are usually fitted with a bottle sleeve at the top to seal the pump head and prevent it from contacting the outside air. However, the bottle sleeve is not stable. When the vacuum bottle is accidentally dropped or subjected to external force, the bottle sleeve is easy to separate from the bottle body, which not only requires searching but also cleaning.

[0004] Therefore, we propose a vacuum bottle based on an antistatic polymer material with a bottomless, square, snap-lock structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as unstable bottle sleeve installation, easy separation of the bottle sleeve from the bottle body when the vacuum bottle is accidentally dropped or subjected to external force, which not only requires searching but also cleaning. The invention proposes a vacuum bottle based on an antistatic polymer material with a bottomless, square, strong-lock structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Vacuum bottles made of antistatic polymer material based on a bottomless, square, snap-lock structure include:

[0008] A square bottle body, with a pump head located at the top center of the bottle body;

[0009] The bottle sleeve is fitted onto the top of the bottle body. The bottom of the bottle sleeve has two symmetrically arranged clearance openings. Connecting blocks are fixed on both inner walls of the bottle sleeve. The connecting blocks are located on one side of the clearance openings, and a slot is opened through one side of the connecting blocks.

[0010] Two connectors are symmetrically fixed at the top edge of the bottle. Each connector includes a mounting shell with an opening on one side. A strip groove adapted to the connecting block is opened through the surface of the mounting shell. A T-shaped slider is slidably connected inside the mounting shell. A rectangular groove is opened on the surface of the slider. A trapezoidal locking block is fixed on the inner wall of one side of the rectangular groove. The locking block and the locking groove are used in conjunction. Two spring pieces are fixed between the slider and the mounting shell.

[0011] In one possible design, limit grooves are provided on both sides of the slider, and limit blocks are fixed on both inner walls of the mounting shell. The limit grooves and limit blocks are used in conjunction.

[0012] In one possible design, the bottom edge of the connecting block is chamfered.

[0013] In one possible design, two positioning grooves are symmetrically formed on the top edge of the bottle body, and the positioning grooves are U-shaped and fit the bottle sleeve.

[0014] In one possible design, both the outer wall of the bottle body and the outer wall of the bottle sleeve are provided with an antistatic coating.

[0015] In one possible design, the antistatic coating is titanium suboxide.

[0016] In this application, when removing the bottle cover, one hand is used to press down on both sliders simultaneously and move them toward the pump head, so that the sliders move the locking block and disengage it from the slot, and then the bottle cover is removed with the other hand;

[0017] When installing the bottle sleeve, align the mounting shell and the clearance opening, and insert the connecting block into the strip groove. The connecting block contacts the inclined surface above the trapezoidal block, thereby pushing the trapezoidal block to move laterally. At this time, the spring is compressed. When the slot and the block align, the spring pushes the block to reset and enter the slot, thus completing the limiting of the bottle sleeve. At the same time, the bottle sleeve fits perfectly on the top of the bottle body, and the bottom of the bottle sleeve aligns with the positioning groove.

[0018] Beneficial effects: In this utility model, the vacuum bottle based on the bottomless square strong buckle structure of the antistatic polymer material can strongly restrict the bottle sleeve through the setting of the structure such as the card block, card slot and slider, which avoids the problem that the bottle sleeve is easy to separate from the bottle body when the vacuum bottle is accidentally dropped or subjected to external force.

[0019] In this utility model, the vacuum bottle made of antistatic polymer material based on a bottomless square buckle structure can position the slider and the bottle sleeve by setting structures such as limiting blocks, limiting grooves and positioning grooves, thus ensuring the stability of the overall structure.

[0020] In this invention, the bottle sleeve can be strongly restrained, avoiding the problem that the bottle sleeve is easy to separate from the bottle body when the vacuum bottle is accidentally dropped or subjected to external force. The slider and the bottle sleeve can be positioned to ensure the stability of the overall structure. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In one embodiment: Refer to Figures 1-4 The vacuum bottle includes: a bottle body 1, and a pump head 3 fixedly installed at the top center of the bottle body 1. The pump head 3 adopts a conventional vacuum pump structure.

[0028] The bottle sleeve 2 is fitted onto the top of the bottle body 1, with two symmetrically arranged clearance openings 5 ​​at its bottom. A connecting block 6 is fixedly installed on each of the inner walls of both sides of the bottle sleeve 2, located on one side of the clearance opening 5. The connecting block 6 is injection molded from ABS engineering plastic, and its bottom edge is chamfered 8 at a 45-degree angle to facilitate its insertion into the strip groove 10. A through groove 7 is formed on the surface of the connecting block 6.

[0029] Two connectors are symmetrically fixed to the top edge of the bottle body 1. Each connector includes a mounting shell 9, one side of which is open and the opening direction is away from the pump head 3. A strip groove 10 is formed through the surface of the mounting shell 9, the width of which is clearance-fitted with the thickness of the connecting block 6. A T-shaped slider 11 is slidably connected inside the mounting shell 9. A limiting groove 15 is formed on each side of the slider 11, and limiting blocks 16 are correspondingly fixed to the inner walls of both sides of the mounting shell 9. The limiting grooves 15 and the limiting blocks 16 cooperate to prevent the slider 11 from detaching from the mounting shell 9.

[0030] A rectangular groove 13 is formed on the surface of the slider 11, and a trapezoidal locking block 14 is fixedly installed on the inner wall of one side of the rectangular groove 13. The locking block 14 is made of POM material, and its bevel angle matches the chamfer angle 8 of the connecting block 6. Two spring pieces 12 are fixedly installed between the slider 11 and the mounting shell 9. The spring pieces 12 are made of stainless steel and formed by heat treatment to provide rebound force.

[0031] An antistatic coating is applied to both the outer wall of the bottle body 1 and the outer wall of the bottle sleeve 2. The antistatic coating is formed by magnetron sputtering of titanium suboxide material, which effectively conducts away static charge.

[0032] When installing bottle sleeve 2, align the clearance opening 5 of bottle sleeve 2 with the mounting shell 9, and slide the connecting block 6 into the strip groove 10. The chamfer 8 at the bottom of the connecting block 6 contacts the inclined surface of the locking block 14, generating a horizontal force that pushes the slider 11 into the mounting shell 9. During this process, the spring piece 12 accumulates elastic potential energy. When the connecting block 6 is fully inserted into the bottom of the strip groove 10, the locking groove 7 and the locking block 14 are accurately aligned. The spring piece 12 releases energy to push the locking block 14 into the locking groove 7, completing the mechanical interlock. At this time, the bottom of the bottle sleeve 2 is completely fitted with the positioning groove 4, forming radial positioning.

[0033] When removing the bottle sleeve 2, press both sliders 11 simultaneously to move them toward the pump head 3. The sliders 11 will cause the locking block 14 to disengage from the slot 7. Once the locking block 14 has completely disengaged from the slot 7, the bottle sleeve 2 can be easily removed axially.

[0034] This application can be used in the field of vacuum bottles, or in other fields applicable to this application.

[0035] In another embodiment: a vacuum bottle based on an antistatic polymer material with a bottomless square buckle structure is applied to the field of vacuum bottles;

[0036] In another aspect of this embodiment, two U-shaped positioning grooves 4 are symmetrically opened on the top edge of the bottle body 1. The curvature of the positioning grooves 4 is adapted to the bottom contour of the bottle sleeve 2, which can improve the stability of the structure.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
