Description

Technical Field

[0001] The utility model specifically relates to the technical field of rubber stoppers, in particular to a brominated butyl rubber stopper for injection. Background Art

[0002] Bromobutyl rubber (BIIR) is an isobutylene-isoprene copolymer elastomer containing active bromine. Because bromobutyl rubber has a substantially saturated backbone like butyl rubber, it possesses many of the performance characteristics of butyl polymers, such as higher physical strength, better vibration damping, low permeability, and resistance to aging and weathering.

[0003] At present, traditional rubber stoppers are made of plastic. When installing and using traditional plastic rubber stoppers, the rubber stoppers are directly inserted into the bottle mouth and need to be fixed by aluminum sheets. Therefore, when using, the aluminum sheet needs to be opened first, and then the medicine in the bottle is extracted or mixed by passing the syringe through the rubber stopper, which makes the medical staff troublesome and laborious when performing the operation. Compared with bromobutyl rubber stoppers, traditional rubber stoppers have poor permeability and poor aging resistance. When such rubber stoppers are used in medical equipment, major safety accidents are very likely to occur.

[0004] Therefore, we provide a brominated butyl rubber stopper for injection. In this device, a top cover and a sealing ring are provided on the stopper body, and a plurality of protrusions are provided on the sealing ring. In this way, the contact area between the stopper and the bottle mouth can be effectively increased during installation; the stability between the stopper and the bottle mouth can be effectively ensured. A groove is provided on the top cover, and an adhesive sheet is provided in the groove. The adhesive sheet is fixedly connected to the pull ring. When the stopper needs to be removed, it is pulled out through the pull ring to quickly remove the medicine in the bottle. Utility Model Content

[0005] The purpose of the utility model is to provide a brominated butyl rubber stopper for injection. In the device, a convex column is added to the sealing ring of the rubber stopper to achieve the contact area between the rubber stopper and the bottle mouth, thereby increasing the stability between the rubber stopper and the bottle mouth, and no longer needing to be fixed by other devices. When the rubber stopper needs to be removed, it can be achieved through the pull ring provided on the top cover, so that the medicine in the bottle can be poured out; thereby solving the problems raised in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A bromobutyl rubber stopper for injection, comprising a stopper body; the stopper body comprising a top cover and a sealing ring; wherein the stopper body is provided with ribs; the ribs are provided in plurality;

[0008] As a further technical solution of the present invention, the sealing ring is provided at the bottom of the top cover and is provided as an integral unit. A plurality of protrusions are provided on the surface of the sealing ring. The diameter of the sealing ring is three quarters of the diameter of the top cover.

[0009] The top cover is further provided with a groove; the groove is annular; an adhesive sheet is fixedly provided in the groove;

[0010] The adhesive sheet is bonded and fixed to a portion of the pull ring at a side away from the bottom surface of the groove; and the pull ring is fitted inside the groove.

[0011] As a further technical solution of the present invention, a center groove is provided in the middle of the top cover;

[0012] As a further technical solution of the present invention, the plurality of protruding columns are arranged in a ring array.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model, when in use, inserts the sealing ring on the plug body into the bottle mouth, and realizes the friction area between the plug body and the bottle mouth by means of a plurality of protrusions arranged on the surface of the sealing ring. In this way, when in use, the stability of the plug body and the bottle mouth bracket can be effectively guaranteed, and there is no need to fix the plug body and the bottle mouth by means of an external structure. When the plug body needs to be taken out during use, a pull ring is provided in the groove provided on the top cover, and the pull ring is fixedly connected to the groove by an adhesive sheet. The pull ring is lifted and the plug body is pulled out from the bottle mouth with force, so that the medicine in the bottle can be quickly taken out, which can greatly reduce the operation time during use.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 In an embodiment of the present invention, a bromobutyl rubber stopper for injection includes a stopper body 1; the stopper body 1 includes a top cover 10 and a sealing ring 11; wherein the stopper body 1 is provided with a rib 13; the rib 13 is provided with a plurality of ribs;

[0022] The sealing ring 11 is provided at the bottom of the top cover 10 and is provided as an integral unit. A plurality of protrusions 12 are provided on the surface of the sealing ring 11. The diameter of the sealing ring 11 is three quarters of the diameter of the top cover 10.

[0023] The top cover 10 is further provided with a groove 15; the groove 15 is annular; an adhesive sheet 16 is fixedly provided in the groove 15;

[0024] By adopting the above technical solution, when in use, the sealing ring 11 on the plug body 1 is inserted into the bottle mouth, and the friction area between the plug body 1 and the bottle mouth is realized by the multiple protrusions 12 provided on the surface of the sealing ring 11. In this way, the stability of the plug body 1 and the bottle mouth bracket can be effectively ensured during use;

[0025] The adhesive sheet 16 is bonded and fixed to a portion of the pull ring 17 at a side away from the bottom surface of the groove 15 ; the pull ring 17 is fitted into the interior of the groove 15 .
