Abstract
This utility model relates to a kind of bivalve Easy-folding composite cover, comprises enclosing cover, inner cap and the pad between enclosing cover and inner cap, and described pad designs for integral type, and shape is the butterfly that two circular portion overlaps form afterwards.This utility model infusion bottle or transfusion bag bivalve Easy-folding composite cover, its pad, inner cap boss, enclosing cover boss are the butterfly that two circular portion overlaps form afterwards, which save raw material, reduce costs, two thread a needle hole use time not secondary pollution, pad can provide larger retraction force, make the colloid of pad hold syringe needle tightly, prevent pad from sliding and caving in, do not occur in the dead of night, reasonable in design, safe and reliable.
Description
Technical field
This utility model relates to polypropylene Combined cover of infusion container, refers to a kind of polypropylene infusion vessel bivalve Easy-folding composite cover especially.
Background technology
Current medical infusion bottle or bag sealing combined cover, mostly by enclosing cover, pad and inner cap three part form; After medicinal liquid is poured into infusion bottle by pharmaceutical factory, composite cover heating is welded on bottleneck and is used for sealing, cover outward and be provided with draw ring, when medical worker is to patient's medication, enclosing cover draw ring can be pulled upwardly, itself and enclosing cover coupling part entirety is made to depart from enclosing cover and expose pad, through piercing through pad and inner cap comes for injecting or output medicinal liquid.The effect of pad, mainly for better tightness, is avoided causing medicinal liquid to ooze out when infusing.After the unlatching of enclosing cover draw ring, also wanting secondary sterilization when infusing, now having designed bivalve Easy-folding composite cover.Fracture when making up a prescription one of them flap, after piercing through exposed pad and inner cap, in bottle, injects liquid medicine dispensation; Only need fracture during transfusion after another flap pierces through exposed pad and inner cap and can outwards infuse, avoid secondary pollution, save disinfection cost.
Existing bivalve Easy-folding composite cover, in it, pad is divided into 400-Meter Dash channel type and dumbbell shape (also known as 8-shaped), the shape that its shapes of interior pad of 400 racetrack fences up like 400-Meter Dash road, its shortcoming is that syringe or transfusion device pierce through rear easy generation pad and slide, and causes in the dead of night; Dumbbell shape (8-shaped) its shortcoming is after syringe or transfusion device pierce through, easily interior pad is inserted into bottle interior, and pad is after by needle pierces, retraction force is limited, puncturing hole retraction can not be held tightly with puncture needle, especially circular portion radius is less than normal, easily when infusing, leakage occurs.
Utility model content
The purpose of this utility model is to provide a kind of plastic container for infusion bivalve Easy-folding composite cover, which save raw material, reduce costs, two thread a needle hole use time there is no secondary pollution, pad can provide larger retraction force, makes the colloid of pad hold syringe needle tightly, does not occur in the dead of night, reasonable in design, safe and reliable.
For this reason, according to an aspect of the present utility model, bivalve Easy-folding composite cover is provided, comprise enclosing cover, inner cap and the pad between enclosing cover and inner cap, it is characterized in that, described pad designs for integral type, and shape is the butterfly that two circular portion overlaps form afterwards.
Preferably, the boss of described enclosing cover is butterfly.
Preferably, be provided with two above the boss of described enclosing cover and pull folding valve.
Preferably, close the lid in described and be provided with butterfly positioning boss.
Preferably, described pad is provided with detent and pinprick, and detent and the interior positioning boss closed the lid are combined closely.
Preferably, the inner side of the butterfly boss of described enclosing cover and pad fasten.
Butterfly described in the utility model is the overlapping decentraction of two circular portions, the butterfly of composition.
The inner cap of this utility model composite cover, pad and enclosing cover, by being combined as a whole after pressing.
The heating of this utility model composite cover is welded on infusion bottle or transfusion bag mouth, one of them that when making up a prescription, folding covers outside falling pulls folding valve, expose corresponding acupuncture mouth, by piercing through acupuncture mouth and inner cap, medicinal liquid is input in bottle, during transfusion folding fall outer cover another pull folding valve, expose corresponding acupuncture mouth, by piercing through acupuncture mouth and medicinal liquid exports by inner cap.
This utility model infusion bottle or bag bivalve Easy-folding composite cover, its pad, inner cap boss, enclosing cover groove and boss are the butterfly of two circular portion overlaps, which save raw material, reduce costs, two thread a needle hole use time not secondary pollution, pad can provide larger retraction force, make the colloid of pad hold syringe needle tightly, prevent pad from sliding and caving in, do not occur in the dead of night, reasonable in design, safe and reliable.
