[0028] The utility model discloses a freeze-dried film-coated double-fork rubber plug which has the following beneficial effects:

[0029] 1. The freeze-dried film-coated double-fork rubber plug reduces the height of the plug leg compared to existing double-fork rubber plugs, and adds an R-angle arc surface at the bottom of the plug leg to achieve a rounded effect, reducing the force on the film material during extrusion and stretching, making it easier to coat the outside of the plug body and plug leg, reducing the risk of film breakage, and the new plug design reduces the height of the plug leg. This change not only reduces the overall weight of the plug, but also makes the plug unit more flexible and convenient during installation and use. Reducing the height also helps to reduce the deformation of the plug unit under stress, thereby improving its structural stability and durability. The new plug design makes it easier to coat the outside of the plug body and plug leg due to the reduction in the height of the plug leg and the addition of the R-angle arc surface. The rounded corners and reduced stress allow the film material to adhere more tightly to the surface of the plug, improving the quality and aesthetics of the coating.

[0030] 2. The freeze-dried film-coated double-fork rubber plug has a material taking unit at the end of the plug body, and the installation sleeve is connected to the plug body. When taking the freeze-dried material from the glass bottle, the glass bottle and the plug unit are inverted, the freeze-dried material is placed into the taking rack, and then the taking rack is pulled towards the discharge sleeve, compressing the spring member until the taking rack enters the discharge sleeve. Then the freeze-dried material in the taking rack is poured out, and the taking rack is reset under the action of the spring member, thereby facilitating the taking of individual freeze-dried materials and preventing contamination of other freeze-dried materials.

[0031] 3. The freeze-dried film-coated double-fork rubber plug uses the sealing plate to tightly fit the inner wall of the sealing groove under the action of the spring member in the normal state, thereby sealing the installation sleeve and the discharge sleeve. After pulling the sealing plate to separate it from the inner wall of the sealing groove, the bottom of the taking rack can still seal the lower half of the sealing groove, thereby still sealing the installation sleeve and the discharge sleeve.

[0032] 4. The freeze-dried film-coated double-fork rubber plug allows the freeze-dried material entering the installation sleeve to enter the taking cavity under the action of multiple taking ports, and the internal space of the taking cavity is limited, allowing only a single freeze-dried material to exist, thereby allowing the taking of individual freeze-dried materials. After the freeze-dried material is brought into the discharge cavity using the taking rack, the freeze-dried material in the taking rack can be taken out using the discharge port.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model is clearly and completely described, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0043] The application provides a freeze-dried film-coated double-fork rubber plug, which solves the problem that the double-fork structure is more likely to cause film breakage in the production process, so that the double-fork rubber plug cannot be mass-produced, and if the freeze-dried medicine needs to be taken out after the double-fork rubber plug is inserted into the bottle opening, the double-fork rubber plug needs to be pulled out, and then the freeze-dried medicine is poured out, so that multiple freeze-dried medicines are easily poured out at the same time, and pollution is caused.

[0044] Compared with the existing double-fork rubber plug, the height of the rubber plug leg 12 is reduced, and an R-angle arc surface 13 is added at the bottom of the rubber plug leg 12 to achieve a rounded effect, thereby reducing the force acting on the film material during extrusion and stretching, and facilitating the film coating work on the outer side of the rubber plug body 11 and the rubber plug leg 12, and reducing the film material breakage.

[0045] The new rubber plug design reduces the height of the rubber plug leg 12. This change not only reduces the overall weight of the rubber plug, but also makes the rubber plug unit 1 more flexible and convenient during installation and use. Reducing the height also helps to reduce the deformation of the rubber plug unit 1 when subjected to stress, thereby improving its structural stability and durability.

[0046] A material taking unit 2 is provided at the end of the rubber plug body 11, and a mounting sleeve 21 is connected with the rubber plug body 11. When taking the material from the glass bottle containing the freeze-dried material, the glass bottle and the rubber plug unit 1 are inverted, so that the freeze-dried material enters the material taking rack 23, and then the material taking rack 23 is pulled towards the material discharging sleeve 22, compressing the spring member 24, until the material taking rack 23 enters the material discharging sleeve 22, and then the freeze-dried material in the material taking rack 23 is poured out. After the material taking rack 23 is released, the material taking rack 23 is reset under the action of the spring member 24, thereby facilitating the taking of individual freeze-dried materials and avoiding contamination of other freeze-dried materials.

[0047] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings and specific embodiments in the specification.

[0053] The rubber plug leg 12 is provided at the end of the rubber plug body 11 and is integrally formed with the rubber plug body 11, and an R-angle arc surface 13 is formed at the bottom of the rubber plug leg 12;

[0054] The material taking unit 2 is installed at the end of the rubber plug body 11, and the material taking unit 2 comprises:

[0055] The mounting sleeve 21;

[0056] The material discharging sleeve 22 is provided at the end of the mounting sleeve 21;

[0057] A material taking frame 23 is arranged between the discharging sleeve 22 and the mounting sleeve 21, and can be used for taking out a single freeze-dried product;

[0058] A spring member 24 is arranged between the material taking frame 23 and the discharging sleeve 22, and is used for fixing the position of the material taking frame 23.

[0059] Further, the outer wall of the rubber plug body 11 and the rubber plug leg 12 is provided with a positioning block 14.

[0060] Compared with the existing double-fork rubber plug, the height of the rubber plug leg 12 is reduced, and an R-angle arc surface 13 is added at the bottom of the rubber plug leg 12, so as to achieve a rounded effect, reduce the force acting on the film material during extrusion and stretching, and make it more convenient to coat the outer side of the rubber plug body 11 and the rubber plug leg 12. The outer side of the positioning block 14 is rounded to achieve a rounded effect.

[0061] The height of the rubber plug leg 12 is reduced in the new rubber plug design. This change not only reduces the overall weight of the rubber plug, but also makes the rubber plug unit 1 more flexible and convenient during installation and use. Reducing the height also helps to reduce the deformation of the rubber plug unit 1 when it is under stress, thereby improving its structural stability and durability.

[0062] Due to the reduction of the height of the rubber plug leg 12 and the addition of the R-angle arc surface 13, the new rubber plug design makes it easier to coat the outer side of the rubber plug body 11 and the rubber plug leg 12. The rounded corners and reduced stress allow the film material to be more tightly attached to the surface of the rubber plug, improving the quality and aesthetics of the coating.
