Problems solved by technology

[0004] However, the existing infusion containers generally have the following defects: because the film layer on the top of the inner cover of the infusion container has a seam line when the inner cover of the infusion container is welded, when the machine automatically assembles the gasket, the symmetrical circular frustum groove on the gasket sometimes It will overlap with the suture line on the inner cover. When infusion, the needle passes through the groove of the round table body to withstand the suture line. Its resistance is large, it is difficult to puncture at one time, and it is not easy to operate, resulting in unnecessary waste in actual use.

Abstract

The invention discloses an infusion container which comprises a body, an outer cover and an inner cover, wherein an easily-pulled cover is arranged at the top of the outer cover and comprises an easily-pulled sealing piece and an easily-pulled ring; an easily-pulled press mark is arranged on the periphery of the easily-pulled sealing piece; the easily-pulled ring is connected to the easily-pulled sealing piece; a thin film layer is arranged at the top of the inner cover; a gasket is arranged between the outer cover and the inner cover; at least three grooves in which infusion needles are inserted are formed on the gasket and are not positioned on the same straight line; and the outer cover, the gasket and the inner cover are connected with a neck of the infusion container in a sealing manner to form a completed infusion container. The invention has the advantages as follows: during infusion, the grooves on the gaskets are not completely overlapped with a welding joint line of the inner cover; the infusion needles have small puncture resistance so as to facilitate the puncture; and the infusion container has favorable safety, cost economization and infusion function and / or medicine adding function and is simple and convenient for operation.

Description

technical field [0001] The invention belongs to the technical field of medical transfusion packaging, in particular to an infusion container with a sealing gasket on the cover. Background technique [0002] The infusion container is a commonly used infusion tool, and its sealing cap is required to have the function of infusion, and preferably also has the function of adding medicine. [0003] Most of the current large medical infusion containers are made of glass or polymer materials, and the large infusion containers made of polymer materials are not fragile and are widely used. The sealing device of existing plastic infusion container or infusion bag all is to seal container opening with combined plastic sealing cover, and this sealing cover is made up of three parts: inner cover, outer cover and the gasket placed between inner cover and outer cover , There is a symmetrical circular groove on the gasket. When in use, pull the pull ring on the top of the outer cover, and t...
