Problems solved by technology

[0006] The purpose of the present invention is to provide a composite gasket and a combined cover for large transfusion packaging. While maintaining the original resilience of the gasket and good holding performance for the puncture device, the hardness of the gasket is increased through the setting of the skeleton. It greatly improves the support of the gasket, and ingeniously solves the problem that the hardness and elasticity of the gasket cannot be balanced

Embodiment approach 1

[0034] like Figure 1 to Figure 4 As shown, the present invention provides a composite gasket, the composite gasket includes an elastic body 2 and a support frame 1, the support frame 1 is used to support the elastic body 2, and a middle position of the elastic body 2 is provided for puncture At least one puncture portion 201 into which the device is inserted, and an annular sealing portion 204 is formed on the edge of the elastic body 2 along the circumferential direction of the elastic body 2. The support frame 1 is arranged inside the elastic body 2 and is located between the puncturing portion 201 and the sealing portion. The position between 204 enables the elastic body 2 to retain the original gasket in this position to hold the puncture, rebound and seal, and reduce chip falling, etc., and the part that cooperates with the cover can also achieve good contact sealing. sex.

[0035] In the present invention, a support frame 1 is added in the elastic body 2 in the shape o...

Embodiment approach 2

[0054] The present invention provides a combined cover for large infusion packaging, the combined cover for large infusion packaging includes a cover body and the above-mentioned composite gasket, the composite gasket is arranged inside the cover body, and the elastic body 2 of the composite gasket is connected to the cover. The inner wall of the body is closely attached to achieve a good sealing effect between the composite gasket and the cover body.

[0055] The production process of the combined cover for medium and large infusion packaging of the present invention is as follows: the above-mentioned composite gasket is directly injection-molded by a two-color injection molding machine, and then the composite gasket and the cover body (including the outer cover and the inner cover) are assembled together by an assembly machine, The assembly of the combined cover for the large infusion package can be completed.

Abstract

The invention relates to a composite gasket and a combined cover for large infusion packaging, the composite gasket comprises a lamellar elastic main body and a supporting framework for supporting the elastic main body, and at least one puncture part for inserting a puncture outfit is arranged in the middle of the elastic main body; an annular sealing part is formed on the edge of the elastic body in the circumferential direction of the elastic body, and the supporting framework is arranged in the elastic body and located between the puncturing part and the sealing part. According to the combined cover, the technical problems that a gasket in the combined cover for large infusion packaging is high in cost and poor in sealing performance and supporting performance are solved.

Description

Technical field [0001] The invention relates to the field of large infusion packaging, and in particular to a composite gasket and a combined cover for large infusion packaging. Background technique [0002] Traditional combination covers for large infusion packages are basically assembled using a plastic outer cover and a rubber (or elastomer) gasket. The size of the gasket is larger, the cost is higher, and the performance requirements of the gasket are higher. [0003] In recent years, although two-color molding technology has been used to mold the elastomer and the outer cover at one time, which simplifies assembly, this production method is mostly used on lids that use easy-tear film opening methods. If it is used on lids with other opening methods, However, due to the relatively high process and cost, and the limitations of the support performance and cost of the elastomer, the effect is not ideal. In addition, rubber gaskets and elastomer gaskets have their own shor...
