Description
Technical field
This practicality belongs to the medical packaging field, is specifically related to a kind of single plug bivalve combination sealing bag.
Background technology
The sealing bag that uses in pharmaceuticals industry mainly seals through single plug seal cover, is provided with a rubber stopper in this seal cover, and Medicated needle of syringe and infusion needle all insert in the bag through rubber stopper.Two syringe needles insert in same rubber stopper and extract, and occur falling the problem of plug and poor sealing easily.Existing sealing bag once is connected molding with seal cover through heating, and is inseparable between the two.When this structure makes in sealing bag dosing, can only add liquid preparation, and can not add solid drugs such as powder and tablet, make things convenient for inadequately.
The utility model content
The purpose of this utility model promptly is to overcome the deficiency of prior art, and a kind of single plug bivalve combination sealing bag is provided, and it has easy to use, good seal performance with fall to fill in the low advantage of frequency.
The purpose of this utility model realizes through following technical scheme:
A kind of single plug bivalve combination sealing bag, it comprises bag and lid, lid is connected with the opening of bag; Offer delivery outlet and input hole on the lid vertically, the hole wall A of delivery outlet is closed taper shape, and hole wall A surrounds grafting space A; The hole wall B of delivery outlet is the closed cylindrical shape in lower end; Hole wall B surrounds the grafting space B, is provided with plug in the grafting space B, and plug cooperates with hole wall B;
It also comprises diaphragm seal, and the top of diaphragm seal is provided with draw ring, and the bottom margin of diaphragm seal is provided with contact ring, and contact ring is connected with the top of lid, and diaphragm seal covers delivery outlet and input hole fully.
The outer surface of opening is provided with external screw thread, and the bottom of described lid is provided with seal section, and the inner surface of seal section is provided with female thread, and opening and lid are through being threaded.
The advantage of this utility model is:
1. Medicated needle of syringe inserts in the bag through input hole and plug, and infusion needle inserts in the bag through delivery outlet, and two syringe needles separately are not prone to the problem of plug, and only are inserted with thinner Medicated needle of syringe on the plug, are not easy to occur the situation of poor sealing;
2. bag and lid are through being threaded, and both can add solid drugs such as powder and tablet after separating in bag, easy to use.
