Description

Technical Field

[0001] The utility model relates to the technical field of medicine packaging, in particular to a drop plastic plug cover and a syringe bottle container. Background Art

[0002] Currently, infusion caps on the market typically consist of an outer cap, an inner cap, and a rubber stopper. The inner and outer caps are made of different materials, modified to meet specific application requirements. These materials typically include polypropylene, polyethylene, and polyolefins, sometimes with additives added to improve performance. However, while these material combinations meet application requirements to a certain extent, they also bring some unavoidable problems.

[0003] The use of a variety of raw materials, combined with the complex modification process required to refine these materials, results in high costs. During the puncture process, the hard materials of the inner cap and stopper easily produce a significant amount of debris, which can enter the medication solution and pose a threat to patient safety. Furthermore, existing infusion caps often lack sufficient adhesion between the stopper and the cap body, which can cause the stopper to fall off during transportation or use, compromising the seal and safety of the medication. Utility Model Content

[0004] One of the purposes of the utility model is to provide a medicine cover for a drop plastic plug, so as to reduce the generation of puncture debris and enhance the firmness of the plug.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: a drop-molding plug medicine cap, comprising a cap body and a puncture part arranged on the cap body, characterized in that: the puncture part comprises a plug accommodating hole arranged on the top of the cap body and a plug located in the plug accommodating hole, the bottom of the plug accommodating hole is provided with a supporting plate for supporting the plug, the plug is formed by drop-molding of TPE material, the inner wall surface of the plug accommodating hole is a frosted surface for increasing the adhesion with the plug, and the top of the puncture part is also provided with a diaphragm for protecting the plug.

[0006] Preferably, the top of the cover body is fastened to the rubber plug by thermoplastic molding.

[0007] More preferably, the cover body and the support plate are an integrally formed structure.

[0008] More preferably, the thickness of the central puncture area of the rubber plug is 5-7 mm.

[0009] More preferably, the membrane is aluminum foil or non-PVC film.

[0010] More preferably, there are two puncture portions, one large and one small, which are arranged side by side on the cover.

[0011] In addition, the utility model also provides a vial container, which includes a vial body, and the vial body is provided with the above-mentioned drop plastic plug cover.

[0012] Among them, an elastic gasket is provided between the top of the bottle mouth of the syringe bottle body and the cover body, and the bottom end of the cover body is provided with a locking tooth for buckling the bottom end of the bottle mouth of the syringe bottle body.

[0013] Compared with the existing technology, the present invention uses TPE material as the raw material for the plug and manufactures the plug through drop molding technology. TPE material has good elasticity and flexibility. Compared with traditional hard plastics, it can significantly reduce the debris generated during puncture, thereby improving the safety of infusion. In addition, the inner wall surface of the plug receiving hole is designed to be a frosted surface. This design increases the adhesion between the plug and the cover body, ensuring that the plug is not easy to fall off during use, and enhancing the overall stability and reliability of the medicine cover. The design of the support plate ensures the stability of the plug during the puncture process, reduces the displacement of the plug, thereby improving the sealing performance of the medicine cover and ensuring the storage and use safety of the medicine.

[0024] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0025] It should be noted in advance that, in this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connected," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances. Furthermore, in this utility model, unless otherwise expressly specified or limited, a first feature "above" or "below" a second feature may include direct contact between the first and second features, or may include contact between the first and second features not being in direct contact but through another feature between them. Example

[0026] like Figure 1 and Figure 2 As shown, a drop plastic plug medicine cap includes a cap body 1 and a puncture portion provided on the cap body 1, the puncture portion includes a plug receiving hole 2 provided on the top of the cap body 1 and a plug 3 located in the plug receiving hole 2, a support plate 4 for holding the plug 3 is provided at the bottom of the plug receiving hole 2, the plug 3 is formed by drop molding of TPE material, the inner wall surface of the plug receiving hole 2 is a frosted surface to increase the adhesion with the plug 3, and a diaphragm 5 for protecting the plug 3 is further provided at the top of the puncture portion, and the diaphragm 5 can be connected to the top of the cap body 1 by bonding.

[0027] In the above structure, the top of the cap body 1 is thermoplastically molded to hold the plug 3. This structural design improves the connection strength between the plug 3 and the cap body 1, ensuring that the plug 3 will not fall off during puncture or use, thereby improving the stability and reliability of the medicine cap.

[0028] Preferably, the cap body 1 and the supporting plate 4 are integrally formed, which not only reduces assembly steps, simplifies the production process, and improves production efficiency, but also avoids potential weaknesses at the joints of multiple components, thereby enhancing the overall strength and durability of the medicine cap.

[0029] The thickness of the puncture area in the middle of the plug 3 is 5-7 mm. The thickness within this range can ensure the softness and elasticity of the plug 3 during puncture, reduce puncture debris, and ensure the strength and durability of the plug 3 to avoid deformation or damage after puncture.

[0030] The membrane 5 in this embodiment is aluminum foil or non-PVC film. Aluminum foil or non-PVC film has excellent barrier properties, effectively preventing external contamination, protecting the rubber plug from bacteria and microorganisms, and ensuring the hygienic safety of the drug. In addition, it avoids the harmful substances that PVC may contain, reducing the impact on the environment and human health.

[0031] The drop plastic plug medicine cap provided in the above embodiment can be used as an infusion cap, installed on an infusion bag for puncture infusion, and can also be used as a bottle cap for a syringe bottle container, and has a wide range of application scenarios and market demands. Specifically, when applied to a syringe bottle container, an elastic gasket 7 is provided between the top of the bottle mouth of the syringe bottle body 6 and the cap body 1, and the bottom end of the cap body 1 is provided with a latch 8 for buckling the bottom end of the bottle mouth of the syringe bottle body 6. The elastic gasket 7 can adapt to bottle mouths of different sizes, provide uniform pressure, ensure the sealing between the bottle cap and the bottle mouth, and prevent the liquid medicine from leaking. The design of the latch 8 enables the cap body to firmly buckle the bottom end of the bottle mouth, and even if it is shaken during transportation or use, it can remain stable and prevent the bottle cap from falling off. Since the syringe bottles on the market are inconvenient to use and require special tools to open, the drop plastic plug medicine cap provided by the utility model can be used to take medicine by puncture and can reduce the generation of puncture debris. Example

[0032] The difference between this embodiment and embodiment 1 is that there are two puncture parts, one large and one small, which are arranged side by side on the cover body 1. This allows the medicine cover to adapt to different types of puncture devices, enhances its applicability, can meet various clinical needs, and improves the flexibility and market competitiveness of the product.

[0033] In addition, in this embodiment, the middle portion of the support plate 4 is recessed downward to form a groove portion, and the bottom end of the middle portion of the rubber plug 3 is raised downward to form a protrusion that cooperates with the groove portion, thereby forming an embedded connection method. This structure can significantly improve the stability of the rubber plug 3 in the support plate 4, reduce the possibility of displacement during puncture or use, and this structural design simplifies the assembly process, making it easier to install the rubber plug 3 on the support plate 4, thereby improving production efficiency and assembly accuracy.

[0034] The utility model realizes a drop-molded plastic plug medicine cap by adopting innovative designs such as a TPE material drop-molded rubber plug, a frosted inner wall surface to enhance adhesion, and a thermoplastic molded snap-fit cover body. The medicine cap not only reduces puncture and debris drop, improves sealing and firmness, but also simplifies the manufacturing process and reduces costs through the integrated structure. At the same time, it has versatility and wide applicability, and is suitable for various medical containers such as infusion bags and syringes, significantly improving the safety and convenience of drug use.

[0035] In order to make it easier for ordinary technicians in this field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are better implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
