Outer cover-rubber mat fixing mechanism of plastic infusion container and processing method thereof

Abstract

The invention discloses an outer cover-rubber mat fixing mechanism of a plastic infusion container and a processing method thereof. The outer cover-rubber mat fixing mechanism comprises an outer cover, a rubber mat and a film, wherein a separator is arranged in the outer cover; the peripheral wall of the outer cover extends to form a rubber mat fixing ring, a jacking ring is connected to the rubber mat fixing ring; the rubber mat is fixed by the jacking ring, the rubber mat fixing ring and the separator; the film is arranged on the outer walls of the rub mat, the jacking ring and the rubber mat fixing ring. The processing method comprises the steps of: A, processing of the outer cover: including adopting an injection molding machine and an outer cover injection mold, and making polypropylene material into the outer cover through injection molding; B, processing of the rubber mat: including adopting a vulcanizing machine and a rubber mat mold, and shaping butyl material into the rubber mat through vulcanizing; C, processing of film: including adopting a punch press, and punching aluminum-plastic composite film into the film; D, embedding of the rubber mat: including arranging the rubber mat into the rubber mat fixing ring of the outer cover, heating the jacking ring of the outer cover by a hot-air blower for softening, and then pressing the jacking ring onto the end face of the rubber mat; E, film pasting; including enveloping the jacking ring, the rubber mat and the rubber mat fixing ring with the precast aluminum-plastic composite film for fixing.

Description

technical field [0001] The invention relates to a combined cover of a plastic infusion container, in particular to a fixing mechanism and a processing method for a rubber pad on an outer cover of a plastic infusion container, and belongs to the field of medical packaging. Background technique [0002] Injection medicine is directly injected into the human vein through large infusion, which is a commonly used route of administration. The container for containing the injection is a plastic bottle or plastic bag, and the lid is welded on the interface of the plastic bottle or plastic bag. The existing cover is composed of an outer cover, an inner cover and a rubber pad. During assembly, the prefabricated rubber pad is placed on the top of the inner cavity of the outer cover, and then the inner cover is put into the outer cover, and the inner cover and the outer cover meet the rubber pad. For fixing, an easy-to-open groove is made in the top of the outer cover and is connected w...

AI Technical Summary

Problems solved by technology

There are following disadvantages in the manufacture of this type of plastic infusion container combination cap: one is that the processing of the inner cap needs to open a plastic mold. The rubber pad and the inner cover are assembled after processing separately, and there is a problem of liquid leakage due to improper cooperation during the manufacturing process; third, because the top of the outer cover is equipped with an easy-to-open groove, it is easy to crack the top of the easy-to-open groove during assembly , causing pollution and other consequences
