Abstract
The utility model relates to a polypropylene combined cover for a plastic infusion vessel, which comprises an outer cover and an inner cover, wherein an easy open tank is arranged in a cover top of the outer cover, the upper surface of the cover top is connected with a pull ring, and the outer cover is welded with a plastic bottle mouth after being combined with the inner cover. The polypropylene combined cover for the plastic infusion vessel is characterized in that the upper portion of the inner cover is provided with a sealed connecting pipe, a sealed spacer is arranged in a hole of the sealed connecting pipe, the hole of the sealed connecting pipe is contacted with the outer wall of a puncture outfit of an infusion set, and the inner diameter of the hole of the sealed connecting pipe is smaller than the outer diameter of the puncture outfit of the infusion set. Compared with the prior art, a rubber mat is reduced, thereby preventing liquid medicine from being polluted because of using the rubber mat, and guaranteeing the quality of the liquid medicine. When manufacturing, the structure is simpler, the assembly of the cover is convenient, the cost is reduced, and the safety is higher.
Description
Technical field
This utility model relates to and is used for the supporting composite cover of plastic container for infusion, belongs to the drug packaging field.
Background technology
High-capacity injection (being commonly called as infusion solutions) is directly to import in the human vein, has effect soon, absorbs and waits characteristics fully, therefore, is generally used in medical treatment.The infusion vessel of splendid attire injection mainly comprises vial, plastic bottle and plastic bag, and that described plastic bottle and plastic bag interface generally are the material of Main Ingredients and Appearance with the polypropylene is made, and the lid that is used for plastic bottle or plastic bag interface is a kind of composite cover.Existing composite cover comprises that the rubber cushion between inner cap, enclosing cover and the inside and outside lid forms, described enclosing cover is enclosed in rubber cushion and inner cap outside, and in the caping of enclosing cover, be shaped on easy kerve, connection draw ring on caping, make caping along easily kerve disconnection with the finger pull draw ring during application, expose rubber cushion, the perforator on the transfusion device is thrust bursting inner cap in the rubber cushion, flow out the liquid in the infusion vessel.The effect of rubber cushion: the one, fixedly perforator makes the not landing voluntarily of perforator of thrusting; The 2nd, the elasticity of dependence rubber cushion to sealing between perforator outer wall and the exterior and interior cover, prevents the medicinal liquid seepage.But adopt rubber cushion to exist following shortcoming: the one, second the eleventh of the twelve Earthly Branches diene rubber cushion composition more complicated of generally using contacts the back and pollutes medicinal liquid easily with medicinal liquid at present; The 2nd, rubber cushion bits foam can be brought in the medicinal liquid of infusion vessel during puncture, causes medicinal liquid that foreign body is arranged; The 3rd, rubber cushion contacts with medicinal liquid in the infusion process, and the material in the rubber cushion pollutes medicinal liquid easily; The 4th, block pin hole when syringe needle passes rubber cushion when making up a prescription easily; Five are to use the rubber cushion cost higher, and make, install complicated.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of rubber cushion that do not have to be provided, avoiding the pollution of using rubber cushion to produce, the assurance medicinal liquid is pure, lid is easy to assembly, and production cost reduces, and the higher polypropylene combination cover for plastic infusion container of security performance.
The technical scheme of this utility model polypropylene combination cover for plastic infusion container is: comprise that enclosing cover and inner cap form, be shaped on easy kerve in the caping of described enclosing cover, connection draw ring on caping, enclosing cover welds with plastics spout mutually with inner cap combination back, it is characterized in that described inner cap top is shaped on sealing and takes over, be provided with the sealing partition in the hole that sealing is taken over, described sealing take over that the hole contacts with the perforator outer wall of transfusion device and its internal diameter less than the perforator external diameter of transfusion device.
Polypropylene combination cover for plastic infusion container of the present utility model, being shaped on sealing on the top of inner cap takes over, be shaped on the sealing partition in the hole that sealing is taken over, at first hauling draw ring with finger during use draws back easy kerve, exposing sealing takes over, perforator is inserted in the sealing adapter again, pass the sealing partition, enter transfusion (being shaped on infusion hole in the perforator) in the liquid, the sealing partition plays the seal isolation effect before use, when taking over the hole use, sealing contacts with the outer wall of perforator, have fixing, the effect of ultrasonic puncture device, and its internal diameter closely cooperates when passing less than the perforator external diameter of transfusion device, seal, prevent medicinal liquid seepage and pollution.Compared with the prior art this programme has reduced rubber cushion, avoids guaranteeing quality of liquid medicine because of using rubber cushion to cause the pollution of medicinal liquid.And structure is simpler when making, and lid is easy to assembly, and cost reduces, and safety is higher.
Polypropylene combination cover for plastic infusion container of the present utility model, its enclosing cover and inner cap combination are in the sealing of enclosing cover fully with plastics spout welding back inner cap, guarantee that inner cap is not polluted.Outer wall is taken in its described sealing can be column type or polygonal etc.The hole is taken in its described sealing can be cylindrical hole.Perhaps its described sealing take over hole can be for round taper hole etc.The thickness B of its described sealing partition can be 0.15mm-0.45mm.High H is taken in its described sealing can be 5mm-15mm.Its described inner cap has weldability preferably for there being certain elastic modified polypropene made with the plastic bottle of own liquid drug or the plastics interface of soft bag.
