[0034] The preferred embodiments of the present application will be described in detail below with reference to the drawings, wherein the drawings constitute a part of the present application and serve to explain the principles of the present application together with the embodiments of the present application, but are not intended to limit the scope of the present application.

[0035] Example 1

[0036] One specific embodiment of the present application discloses a sterilization bottle, as shown in Figure 1 , Figure 2 , Figure 3 , comprising: a bottle body 1, a bottle cap 2, a pressure adjusting column 4, a sealing sleeve 5 and a sealing ring 6; the bottle cap 2 is threadedly connected to the upper end of the bottle body 1 and used for closing the bottle body 1; the middle part of the bottle cap 2 is provided with the sealing sleeve 5 penetrating through the bottle cap 2; the pressure adjusting column 4 is slidingly installed in the sealing sleeve 5; the sealing ring 6 is arranged between the sealing sleeve 5 and the pressure adjusting column 4; when the internal pressure of the sterilization bottle is inconsistent with the external pressure, the pressure adjusting column 4 can slide relative to the sealing sleeve 5, thereby adjusting the pressure inside and outside the sterilization bottle to be consistent.

[0037] In this embodiment, as shown in Figure 3 , the sealing ring 6 is nested on the inner wall surface of the sealing sleeve 5. During the up and down sliding of the pressure adjusting column 4, the sealing ring 6 is used to maintain the sealing of the internal and external environment of the sterilization bottle, avoid the external gas entering the sterilization bottle, and maintain the sterilization effect of the internal environment of the bottle.

[0038] In this embodiment, a plurality of sealing rings 6 are arranged in the axial direction of the sealing sleeve 5. As shown in Figure 3 , two sealing rings 6 are arranged on the inner wall surface of the sealing sleeve 5.

[0039] In this embodiment, the sealing ring 6 is made of medical rubber material.

[0040] In this embodiment, the bottle body 1 and the bottle cap 2 are both made of high-temperature-resistant borosilicate glass.

[0041] Furthermore, to prevent the pressure regulating column 4 from disengaging from the sealing sleeve 5, thus causing the bottle cap 2 to be in an open state, in this embodiment, a limiting structure is provided to restrict the displacement stroke of the pressure regulating column 4. For example... Figure 3 As shown, the pressure regulating column 4 is provided with a first limiting structure 7 and a second limiting structure 8 at its upper and lower ends, respectively; the diameters of the first limiting structure 7 and the second limiting structure 8 are larger than the inner diameter of the sealing sleeve 5, which are used to restrict the pressure regulating column 4 from disengaging from the sealing sleeve 5.

[0042] Preferably, such as Figure 3 As shown, the first limiting structure 7 and the second limiting structure 8 are limiting rings or limiting bosses fixedly installed on the outside of the pressure regulating column 4.

[0043] Preferably, after the pressure regulating column 4 and the sealing sleeve 5 are assembled, the first limiting structure 7 and the second limiting structure 8 are connected to the outer sides of the upper and lower ends of the pressure regulating column 4 by bonding or welding.

[0044] In the sterilization process of this invention, the pressure regulating column 4 slides relative to the sealing sleeve 5 to maintain internal and external pressure balance, and a double-layer sealing ring 6 is provided. The double-layer sealing structure ensures the airtightness of the sterilization process. After sterilization, due to the pressure balancing function, the bottle cap can be opened directly, reducing the difficulty of opening the cap, and the contents of the bottle will not splash after opening the cap.

[0045] This invention effectively solves the problem of difficulty in opening traditional sterilization bottles through an innovative pressure balance design, and has good practical value and prospects for promotion.

[0046] Example 2

[0047] A specific embodiment of this utility model provides a sterilization bottle device, such as... Figure 4 , Figure 5 As shown, it includes: the sterilization bottle of Example 1 and the cap-opening bracket. The cap-opening bracket is used to assist in opening the sterilization bottle.

[0048] In this embodiment, as Figure 4As shown, the cover opening support comprises a fixed base 10, a vertical support rod 11, a positioning rib 13, a positioning support 14, a rotating disc 16, a rotating handle 17 and a positioning column 18; the upper surface of the fixed base 10 is provided with the positioning rib 13, and the bottom of the bottle body 1 is provided with a positioning groove 9; the positioning groove 9 can be clamped with the positioning rib 13 to limit the rotation of the bottle body 1 relative to the fixed base 10; the vertical support rod 11 is vertically installed above the fixed base 10; the vertical support rod 11 is provided with the positioning support 14, the rotating disc 16 is rotatably installed on the positioning support 14, the rotating disc 16 is fixedly connected with the rotating handle 17, and then the rotating handle 17 can drive the rotating disc 16 to rotate; the lower end of the rotating disc 16 is fixedly provided with a plurality of positioning columns 18; the upper surface of the bottle cap 2 is provided with a plurality of positioning column sleeves 3; the positioning column 18 can be inserted with the positioning column sleeve 3, and then the rotating disc 16 can rotate the bottle cap 2 to realize non-contact opening of the bottle cap.

[0049] Preferably, as shown in the drawings, Figure 4 the lower end of the rotating handle 17 passes through the positioning support 14 and is fixedly connected with the rotating disc 16; when the rotating handle 17 rotates, it can drive the rotating disc 16 and the positioning column 18 to rotate, and then drive the bottle cap 2 to rotate relative to the bottle body 1, so as to realize non-contact opening of the bottle cap.

[0050] Preferably, the length of the rotating handle 17 is greater than the diameter of the bottle cap 2, and the operating force required for opening the bottle cap is reduced through lever force transmission.

[0051] Further, the upper surface of the fixed base 10 is further provided with a positioning ring 12; the positioning ring 12 is arranged outside the positioning rib 13, and the bottle body 1 of the sterilization bottle can be placed in the positioning ring 12.

[0052] Preferably, as shown in the drawings, Figure 4 the positioning rib 13 is a cross-shaped rib, and the positioning groove 9 is a cross-shaped groove.

[0053] Further, the rotating disc 16 is rotatably installed below the positioning support 14 through a bearing; one side of the positioning support 14 is fixedly connected with a sliding sleeve 15, and the sliding sleeve 15 is slidingly installed outside the vertical support rod 11, so that the positioning support 14 can move up and down relative to the vertical support rod 11.

[0054] Preferably, the upper end of the vertical support rod 11 is provided with a holding handle 19; for holding the cover opening support during opening of the bottle cap.

[0055] Furthermore, a spring (not shown in the figure) is sleeved on the outside of the vertical support rod 11; the upper end of the spring abuts against the lower part of the grip handle 19, and the lower end of the spring abuts against the upper end face of the sliding sleeve 15.

[0056] In this embodiment, by setting a spring, after the bottle cap 2 is completely unscrewed from the bottle body 1, the rotating disk 16 and the positioning post 18 will still press down on the bottle cap 2, so as to prevent external substances from entering the bottle body in case of accidental operation and maintain the effectiveness of sterilization.

[0057] During implementation, the sliding sleeve 15 is moved upward, causing the rotating disk 16 and the positioning post 18 to move upward simultaneously, placing the sterilization bottle in the positioning ring 12, and the positioning groove 9 at the bottom of the bottle body 1 engages with the positioning protrusion 13 on the fixed base 10, so that the bottle body 1 of the sterilization bottle will not rotate; then the sliding sleeve 15 and the rotating disk 16 are moved downward, so that the positioning post 18 is inserted into the positioning post sleeve 3 above the bottle cap 2, as... Figure 5 As shown; then, rotating the rotating handle 17 will drive the rotating disk 16 and the positioning column 18 to rotate, and the positioning column 18 will drive the bottle cap 2 to rotate, realizing non-contact opening of the sterilization bottle; on the one hand, it can avoid burns from the high temperature of the bottle body, and on the other hand, due to the limiting effect of the rotating disk 16 and the positioning column 18 during the opening process, the bottle cap 2 will not fly out, and the opening process is safe and reliable.

[0058] Compared with the prior art, the technical solution provided in this embodiment has at least one of the following beneficial effects:

[0059] 1. Regarding existing bottle containers, after high-temperature and high-pressure sterilization, the pressure difference between the inside and outside of the bottle makes it difficult to open the cap, and there is a risk of recontamination when removing the bottle. The sterilization bottle device of this utility model has the advantage of being able to open the bottle cap very easily and without contamination.

[0060] 2. The sterilization bottle device of this utility model is simple to operate, has good temperature resistance (can withstand high temperature of 135℃) and chemical stability, and has a very affordable price advantage. It can be reused and is readily available to ordinary experimental personnel or laboratories.

[0061] 3. The sterilization bottle device of this utility model, through the design of the improved bottle cap structure, adjusts the pressure difference between the inside and outside of the bottle through the pressure regulating column 4, making it easy to open the cap. It is easy to open after high temperature and high pressure sterilization. In addition, the sterilization bottle itself is very hot after sterilization, and there is a risk of burns during the opening process. This utility model achieves non-contact opening by setting a positioning column 18 and a rotating disk 16 that cooperate with the positioning column sleeve 3, so that the operator is not likely to be burned when the bottle is at a high temperature. At the same time, the opening process is stable and reliable. After opening, the bottle cap is still placed above the bottle body 1 under the restriction of the positioning column 18 and the rotating disk 16, preventing the entry of external substances and avoiding secondary contamination after sterilization.

[0062] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
