Abstract
The utility model provides an effective waterproof polypropylene combined cover for a plastic transfusion container and relates to a container cover. The effective waterproof polypropylene combined cover for the plastic transfusion container consists of an opening pull ring, a sealed rubber plug, a connecting part and a welding surface, and is characterized in that the upper part of the welding surface is fixedly connected with the connecting part; the sealed rubber plug is arranged on the top end face of the connecting part and is connected with the opening pull ring; and a polygonal cutting mark is formed between the sealed rubber plug and the connecting part. According to the requirement on the product quality caused by soft bag transfusion, the annular cutting mark part of the original rubber plug sealing part is changed into a hexagonal part, so that in the production process of the combined cover, the area of the cutting mark is reduced, the production difficulty of the combined cover is lowered, and quality control of the combined cover is facilitated. The area of the cutting mark is reduced, so that the risk that water enters the combined cover is avoided in the sterilization process of soft bag products, and the opening of the combined cover is not influenced during liquid preparation.
Description
Technical field
This utility model relates to a kind of container top, relates in particular to a kind of polypropylene combination cover for plastic infusion container of effective waterproof.
Background technology
Polypropylene combination cover for plastic infusion container is that soft bag infusion is produced necessary inner packaging material, and PP TYPE and joint weld heat seal are carried out liquid medicine filling after producing soft bag, carry out the composite cover solder up then.Widely used composite cover is draw-ring type in producing now.Draw-ring type composite cover structure mainly is made of draw ring opening section, fluid sealant plug portion, coupling part, solder side interface and composite cover welding.This structure as can be seen, in the production use, solder side is the welding position of interface and composite cover, and soft bag after the fill is sealed, and changes next production process over to.The user in use, finger pull draw ring opening section draws back the fluid sealant plug portion along cut channel, carries out dosing operation.There is a lot of shortcomings in this draw-ring type composite cover, and for example the area of plug hermetic unit cut channel is big, and the light and heavy degree of cut channel is grasped and had any problem, and cut channel kicks the beam, and can make lid in use be difficult for opening, and influences the dosing operation; Cut channel is overweight, in process of production, can make sealing of lid not tight, in the product sterilization process, has water to enter composite cover inside, and composite cover is polluted.
Summary of the invention
This utility model is intended at the deficiency that exists in the background technology, and the polypropylene combination cover for plastic infusion container of a kind of effective waterproof that proposes.
The polypropylene combination cover for plastic infusion container of a kind of effective waterproof of the present utility model, be to be constituted by opener tab, sealing plug, connecting portion and solder side, it is characterized in that the top of solder side fixedly connected connecting portion, the connecting portion top end face is provided with the sealing plug, the sealing plug is connected with opener tab, is provided with the polygon cut channel between sealing plug and the connecting portion.
As further improvement of the utility model, described connecting portion and solder side are cylindric.
As further improvement of the utility model, be provided with the polygon cut channel between sealing plug and the connecting portion and be four to octagon.
This utility model this patent is by improving the structural design of draw-ring type composite cover, according to the prescription of soft bag infusion to product, partly make the annular cut channel of former plug hermetic unit into polygon, also solved simultaneously in the product sterilization process and do not passed a test owing to composite cover cut channel quality, the sterilization water enters composite cover inside, destroys the risk of product hermeticity.The production that this patent enables to satisfy soft bag infusion both can guarantee the effective welding of interface and composite cover with the requirement of polypropylene draw-ring type composite cover, can solve the situation that water is arranged in the composite cover effectively again.In the production process of composite cover, the area of cut channel reduces like this, has reduced the production difficulty of composite cover, is convenient to the control of composite cover quality.Because the cut channel area reduces, in soft bag product sterilization process, avoided having water to enter the risk of composite cover inside, when using, dosing can not influence the unlatching of composite cover again, after eliminating above hidden danger, soft bag infusion production is reduced risk, improving the quality of products has very high meaning.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
The specific embodiment
Polypropylene combination cover for plastic infusion container below in conjunction with accompanying drawing 1 and 2 pairs of a kind of effective waterproof of the present utility model of accompanying drawing is described further.
The polypropylene combination cover for plastic infusion container of a kind of effective waterproof of the present utility model, be to be constituted by opener tab 1, sealing plug 2, connecting portion 3 and solder side 4, it is characterized in that the top of solder side 4 fixedly connected connecting portion 3, connecting portion 3 top end faces are provided with sealing plug 2, sealing plug 2 is connected with opener tab 1, be provided with polygon cut channel 5 between sealing plug 2 and the connecting portion 3, can do tetragon, hexagon or octagon as required.Described connecting portion 3 and solder side 4 are cylindric.
High-capacity injection is commonly called as infusion solutions Large Volume Parenteral, LVP, and the capacity that typically refers to is more than or equal to 50ml and directly by the sterilization of liquids preparation in the intravenous drip input body.Soft bag infusion is the new product in the infusion solutions evolution, since its specifically long-pending little, in light weight be vial weight 1/15, be difficult for fragmentation, anti-collision, transportation facility, chemical stabilization, no leachable, do not fall to consider to be worth doing, disposable use, avoid characteristics such as cross-contamination; Greatly facilitate medical personnel's use, generally be subjected to numerous medical workers' welcome.
