[0036] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0037] The following detailed description of the silicon carbide liquid container stopper structure and overall structure, working principle, and technical effects of the liquid container provided by this utility model, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0038] This utility model provides a medicine container with a silicon carbide medicine container stopper structure at the opening 100 of the container body; the silicon carbide medicine container stopper structure is used to achieve a seal at the opening 100 of the container body, and when necessary, it can also be connected to the inside of the container body through a gas phase pipe or a liquid phase pipe.

[0039] It should be noted that the silicon carbide liquid container stopper structure provided in this embodiment can also be applied to other container structures or bottle structures used to contain gas or liquid phases, and is not limited to silicon carbide liquid containers.

[0040] Please see Figure 1 , Figure 1 This is a front sectional view of the silicon carbide medicine tank stopper structure provided by the present invention. The silicon carbide medicine tank stopper structure provided by the present invention includes a stopper body 200, which is connected to the opening 100 of the medicine tank and is used to seal the opening 100 of the tank.

[0041] Specifically, the barrel stopper body 200 is tapered at one end near the barrel opening 100, and the tapered portion forms a sealing part 210. The sealing part 210 is detachably disposed inside the barrel opening 100, and the sealing part 210 forms a sealing fit with the inner wall of the barrel opening 100, thereby preventing the medicine liquid inside the barrel from overflowing from the barrel opening 100.

[0042] In this embodiment, the barrel stopper body 200 is detachably disposed in the barrel opening 100 via the sealing part 210; the sealing part 210 is gradually tapered, meaning that the cross-sectional area of ​​the sealing part 210 gradually decreases in the axial direction and toward the barrel opening 100, thereby making the sealing part 210 as a whole conical structure.

[0043] Understandably, since the sealing part 210 has an overall conical structure, on the one hand, it can match the opening 100 of the barrel with different inner diameters, thus matching different models of medicine barrels; on the other hand, the conical sealing part 210 can improve the sealing effect between the barrel stopper body 200 and the barrel opening 100.

[0044] In other embodiments, the outer side of the sealing part 210 may also be provided with a plurality of flanges / sealing lips for improving the sealing effect. The flanges or sealing lips abut against the inner edge or inner wall of the barrel opening 100 to improve the sealing effect of the sealing part 210.

[0045] In this embodiment, the rest of the barrel stopper body 200, except for the sealing part 210, can be a columnar structure. When installing the barrel stopper body 200, the columnar structure can be used as a handhold. The operator can connect the barrel stopper body 200 to the barrel opening 100 by holding the handhold.

[0046] Furthermore, in order to ensure that the barrel stopper body 200 and the barrel opening 100 form a sealing relationship, the operator can screw the barrel stopper body 200 in during the installation process to make the sealing part 210 and the barrel opening 100 form an interference fit relationship, so as to achieve a seal on the barrel opening 100.

[0047] In order to prevent the barrel stopper body 200 from shifting axially due to pressure changes inside and outside the barrel during the storage or use of the medicine liquid, in this embodiment, the barrel stopper structure of the silicon carbide medicine liquid barrel also includes a pressure cap 300 for fixing the barrel stopper body 200.

[0048] Specifically, the cap 300 includes a connecting part 310 that connects to the barrel opening 100 and an abutting part 320 for fixing the cap 300; wherein, the inner wall of the connecting part 310 is provided with an internal thread, and the outer wall of the barrel opening 100 is provided with an external thread, and the internal thread and the external thread are connected so that the connecting part 310 and the barrel opening 100 are rotated and tightened together.

[0049] In order to improve the fixing effect of the cap 300 on the barrel stopper body 200, in this embodiment, the outer wall of the barrel stopper body 200 is also provided with a boss 220; when the cap 300 and the barrel stopper body 200 form a fixed relationship, the lower surface of the abutment 320 abuts against the upper surface of the boss 220.

[0050] Specifically, the cap 300 is threaded to the barrel opening 100. During the screwing of the cap 300, the lower surface of the abutment 320 will gradually approach the upper surface of the boss 220 until it abuts against the upper surface of the boss 220, so as to fix the barrel stopper body 200.

[0051] In order to increase the contact area between the boss 220 and the abutment 320, in this embodiment, the boss 220 is generally ring-shaped and is arranged around the outer wall of the barrel stopper body 200. The protrusion height of the boss 220 can be 10mm.

[0052] In other embodiments, the number of protrusions 220 can be multiple, and they are independently spaced from each other. The multiple protrusions 220 are arranged in a ring array on the outer wall of the barrel stopper body 200. In actual operation, similar to this embodiment, as the cap 300 is screwed in, the lower surface of the abutment part 320 gradually approaches the upper surface of the multiple protrusions 220 until it abuts against the upper surface of the multiple protrusions 220 respectively, so as to fix the barrel stopper body 200.

[0053] To reduce wear between the boss 220 and the abutment portion 320, and to prevent damage to the contact area between the buffer member 400 and the boss 220 due to excessive local pressure, a buffer member 400 is provided between the lower surface of the abutment portion 320 and the upper surface of the boss 220 in this embodiment.

[0054] Understandably, during the screwing-in process of the cap 300, the pressure from the abutment 320 will first act on the buffer 400, and then be transmitted from the buffer 400 to the boss 220, so as to avoid wear between the abutment 320 and the boss 220, balance the force distribution, and prevent the contact part between the buffer 400 and the boss 220 from being damaged due to excessive local pressure.

[0055] It should be noted that in this embodiment, there are multiple buffer members 400, which are evenly and equally spaced on the boss 220.

[0056] In several other embodiments, when there are multiple bosses 220, the number of buffers 400 should correspond to the number of bosses 220.

[0057] In this embodiment, the buffer 400 can be any one of a spring, a disc spring, or a flexible pad; considering the difficulty of installation and the cost of use, the buffer 400 can specifically be a spring.

[0058] It should be noted that the buffer 400 is used to provide a flexible connection between the abutment 320 and the boss 220, and only needs to meet the above functions, and is not limited to the types provided in this embodiment.

[0059] In this embodiment, the barrel stopper body 200 is provided with one or more first connecting holes 230, which are used to connect liquid phase pipes or gas phase pipes.

[0060] For example, in this embodiment, the barrel stopper body 200 has two first connecting holes 230 respectively. One of the first connecting holes 230 serves as a liquid extraction hole for connecting to a liquid phase pipeline; the other first connecting hole 230 serves as a venting hole for connecting to a gas phase pipeline.

[0061] In addition, a second connecting hole 330 is provided on the cap 300, and the top end of the barrel stopper body 200 is provided through the second connecting hole 330.

[0062] In the prior art, the barrel stopper body 200 is usually made of PVDF (polyvinylidene fluoride), which will discolor and corrode when in contact with some liquid medicine, thus causing the seal to fail; in order to avoid the above problems, in this embodiment, the barrel stopper body 200 is made of PTFE (polytetrafluoroethylene).

[0063] This embodiment provides a silicon carbide liquid container stopper structure, and the specific assembly process is as follows:

[0064] First, wipe the outer edge of the barrel opening 100. The operator holds the barrel stopper body 200 by hand and screws it in, so that the sealing part 210 and the barrel opening 100 form an interference fit. Then, the cap 300 is threaded to the barrel opening 100 until the abutment part 320 fully abuts against the boss 220 through the buffer 400, thus completing the installation of the barrel stopper body 200. Since the abutment part 320 always abuts against the boss 220 while the cap 300 is threaded to the barrel opening 100, the barrel stopper body 200 is prevented from shifting under pressure or the liquid inside the barrel, thereby preventing the barrel stopper structure from failing.

[0065] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
