Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and more specifically, to a storage bottle with anti-thermal decomposition function. Background Technology

[0002] Storage bottles are containers used to store various items. In biochemistry experiments, storage bottles are commonly used to store various chemical reagents, biological samples, culture media, and other experimental materials.

[0003] Based on the above, the inventors have discovered that when storing experimental materials that decompose or undergo chemical reactions when exposed to light or excessively high temperatures, traditional storage bottles generally have poor heat insulation and light protection effects, and do not have the function of preventing thermal decomposition, resulting in poor overall storage performance. In addition, when sealing experimental materials, traditional storage bottles usually only insert a stopper into the bottle mouth for sealing, but the stopper is prone to loosening during use, thus affecting the overall sealing performance of the storage. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a storage bottle with the function of preventing thermal decomposition, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a storage bottle with anti-thermal decomposition function. It can greatly improve the overall heat insulation and light blocking effect by opening an annular groove and heat insulation cavity in the bottle body, and by adding heat insulation cover and filling with heat insulation material, thus enabling it to prevent the thermal decomposition of materials. This solves the problem of poor storage effect of traditional storage bottles. At the same time, an inner cap and a bottle cap are set at the opening of the bottle body, and the sealing performance at the opening of the bottle body is improved under the action of positioning spring, thus solving the problem of poor sealing performance of traditional storage bottles.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A storage bottle with anti-thermal decomposition function includes a bottle body and a bottle cap threaded to the top of the bottle body. The top of the bottle body is provided with an inner cap, and an annular groove is formed on the top of the bottle body. A heat insulation cover adapted to the annular groove is fixedly connected to the bottom edge of the inner cap, and the bottom end of the heat insulation cover is inserted into the annular groove. A sealing block is fixedly connected to the bottom center of the inner cap, and the bottom of the sealing block is sealed and snapped into the inner cavity of the bottle body. A mounting plate is rotatably connected to the top inner wall of the bottle cap through a bearing. A plurality of positioning springs distributed in an annular pattern are fixedly connected to the bottom of the mounting plate, and the bottom ends of the positioning springs abut against the top of the inner cap.

[0009] Furthermore, the bottle body has a heat insulation cavity inside its side wall, the heat insulation cavity is located inside the annular groove, and the heat insulation cavity is filled with heat insulation material.

[0010] Furthermore, a sealing gasket is fixedly connected to the inner side of the top opening of the bottle body, and the inner side of the sealing gasket is sealed to the outer side of the sealing block.

[0011] Furthermore, a retaining ring is fixedly connected to the inner side of the bottle body, and the top of the retaining ring is in contact with the bottom of the sealing block.

[0012] Furthermore, a limiting groove is formed on the top of the inner cover corresponding to the position of the positioning spring, and the bottom end of the positioning spring abuts against the inner wall of the bottom of the limiting groove.

[0013] Furthermore, a groove is provided at the center of the top of the inner cover, and two symmetrically arranged pull rings are rotatably connected in the groove.

[0014] Furthermore, the outer periphery of the bottle cap is provided with anti-slip texture.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, by opening an annular groove and a heat insulation cavity inside the bottle, inserting the heat insulation cover into the annular groove, and filling the heat insulation cavity with heat insulation material, the double-layer heat insulation and light-blocking setting greatly improves the overall heat insulation and light-blocking effect, enabling the storage bottle to have the function of preventing material thermal decomposition and greatly improving the storage effect of the storage bottle.

[0018] (2) In this solution, an inner cap and a bottle cap are installed at the opening of the bottle body. The bottle cap is threaded and fixed to the top outer periphery of the bottle body, while the sealing plug on the inner cap is sealed and snapped into the inner cavity of the bottle body. When the bottle cap is screwed and fixed to the bottle body, it compresses the positioning spring and causes it to deform. The elastic force generated by the deformation and reset of the positioning spring forms a downward pressing force on the inner cap, so that the inner cap is firmly fixed to the top of the bottle body. This greatly improves the sealing performance at the opening of the bottle body and ensures the sealing effect of the storage bottle for material storage. Attached Figure Description

[0038] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Example:

[0040] Please see Figure 1-5 A storage bottle with anti-thermal decomposition function includes a bottle body 1 and a bottle cap 2 threaded to the top of the bottle body 1. An inner cap 3 is provided on the top of the bottle body 1. An annular groove 4 is formed on the top of the bottle body 1. A heat insulation cover 5 adapted to the annular groove 4 is fixedly connected to the bottom edge of the inner cap 3, and the bottom end of the heat insulation cover 5 is inserted into the annular groove 4. A sealing block 6 is fixedly connected to the bottom center of the inner cap 3. The bottom of the sealing block 6 is sealed and snapped into the inner cavity of the bottle body 1. An mounting plate 7 is rotatably connected to the top inner wall of the bottle cap 2 through a bearing. A plurality of positioning springs 8 distributed in an annular pattern are fixedly connected to the bottom of the mounting plate 7. The bottom end of the positioning springs 8 abuts against the top of the inner cap 3.

[0041] See Figure 5 The bottle body 1 has a heat insulation cavity 9 inside its side wall. The heat insulation cavity 9 is located inside the annular groove 4 and is filled with heat insulation material. The top of the heat insulation cavity 9 is provided with a liquid injection port for filling the heat insulation material. The heat insulation material can be one of aluminum hydroxide solution, glycerin or silica sol.

[0042] See Figure 5 A sealing gasket 10 is fixedly connected to the inside of the top opening of the bottle body 1, and the inside of the sealing gasket 10 is sealed to the outside of the sealing block 6.

[0043] See Figure 5 A retaining ring 11 is fixedly connected to the inner side of the bottle body 1, and the top of the retaining ring 11 is in contact with the bottom of the sealing block 6.

[0044] See Figure 2 and Figure 4 A limiting groove is provided on the top of the inner cover 3 corresponding to the position of the positioning spring 8, and the bottom end of the positioning spring 8 abuts against the inner wall of the bottom of the limiting groove.

[0045] See Figure 2 and Figure 4 The inner cover 3 has a groove at the center of its top, and two symmetrically arranged pull rings 12 are rotatably connected in the groove.

[0046] See Figure 1 The bottle cap 2 has anti-slip texture 13 on its outer periphery.

[0047] In use: First, remove the sealing gasket 10 and inject the heat insulation material into the heat insulation cavity 9 through the injection port on the heat insulation cavity 9. Then, re-fix the sealing gasket 10 in its original position. At this time, place the material to be stored into the inner cavity of the bottle body 1. Align the heat insulation cover 5 on the inner cover 3 with the annular groove 4 and insert it into the annular groove 4. At the same time, the sealing block 6 on the inner cover 3 is also sealed and locked into the inner cavity of the bottle body 1, so that the storage bottle has the function of heat insulation and light protection, effectively preventing the thermal decomposition of the material and improving the storage effect of the storage bottle. Next, fix the bottle cap 2 on the bottle body 1. During the screw fixing process, the bottle cap 2 moves down and causes its positioning spring 8 to deform. The elastic force generated by the deformation of the positioning spring 8 presses the inner cover 3 downward, so that the inner cover 3 is tightly fixed to the top of the bottle body 1, which greatly improves the sealing of the opening of the bottle body 1 and ensures the sealing effect of the storage bottle for material storage.
