Abstract
The utility model discloses a double-pull combined lid which comprises an outer lid, wherein the outer lid comprises a puncture needle inserting end and a bottle connecting end; a rubber mat cavity is arranged in the lid body of the outer lid in a position at the puncture needle inserting end; a rubber mat is arranged in the rubber mat cavity; one end of the rubber mat cavity is communicated with the lid body of the outer lid, and the other end of the rubber mat cavity is communicated with the opening at the top end of the outer lid; and an easily-bent handle is arranged at the opening of the outer lid. Through the adoption of the structure, the double-pull combined lid has the advantages as follows: (1) the opening is convenient and the opening degree is small; (2) the probability of desquamation of the punctured rubber mat is low; (3) the product yield and the transfusion quality are improved; and (4) the structure is simple and the use is convenient.
Description
Technical field
This utility model relates to the transfusion medicine packing field, relates to the supporting composite cover of plastic container for infusion, particularly a kind of two formula composite cover of pulling.
Background technology
High-capacity injection is directly to import human vein, and drug effect is rapid, uses extensively in medical treatment.Infusion solutions plastics packaging material is used generally at present, particularly the plastics composite cover.Existing composite cover is generally draw-ring type, and this draw-ring type composite cover is combined by enclosing cover, rubber cushion, inner cap, and rubber cushion is sandwiched between enclosing cover and the inner cap, forms the sealant of combination between enclosing cover, rubber cushion and the inner cap three.Draw ring is arranged on the top of enclosing cover, when using this composite cover, draws back draw ring, and Transfusion needle pipe can insert rubber cushion, inner cap arrives in the infusion vessel.There is shortcoming in actual use: the one, produce exfoliation when rubber cushion and inner cap puncture and bring in the transfusion, cause the transfusion foreign body, the 2nd, exfoliation stops up pin hole, the 3rd, product cost height.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of inner cap that do not need to use, and puncture exfoliation rate is low, easy to assembly, and production cost is low, two formula composite covers of pulling that security performance is higher.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of two formula composite covers of pulling, comprise enclosing cover, described enclosing cover comprises the puncture needle insertion end, connects the bottle end, be provided with the rubber cushion chamber in the lid of the puncture needle insertion end of described enclosing cover, described rubber cushion intracavity is provided with rubber cushion, and described rubber cushion chamber one end is communicated with in the lid of enclosing cover, the other end in rubber cushion chamber is communicated with the opening on enclosing cover top, and described enclosing cover opening part is provided with foldable handle.
The junction of described foldable handle and enclosing cover is provided with breaks fault trough off with the fingers and thumb.
Be extended with the annular protrusion that snaps in rubber cushion on the tegmental wall of upper end, described rubber cushion chamber, the lower end in described rubber cushion chamber is provided with the spacing snap ring of the rubber cushion that is stretched out by tegmental wall.
Described rubber cushion chamber is two.
Described outer cover outer wall is step-like.
Company's bottle end of described enclosing cover is provided with double-deck welding anchor ring.
The outer wall of described enclosing cover is provided with detent.
Described enclosing cover adopts polypropylene.
Described rubber cushion is the isoprene rubber cushion.
This utility model adopts said structure, has the following advantages: it is convenient 1, to open, and opens little; 2, rubber cushion puncture exfoliation rate is low; 3, improve the finished product rate, improve injection quality; 4, simple in structure, easy to use.

In Fig. 1 ~ Fig. 2,1, enclosing cover; 2, rubber cushion; 3, opening; 4, foldable handle; 5, annular protrusion; 6, snap ring; 7, welding anchor ring; 8, detent.
The specific embodiment
As Fig. 1 ~ a kind of two formula composite covers of pulling shown in Figure 6, comprise enclosing cover 1, whole enclosing cover 1 is that integral type is injection molded, enclosing cover 1 comprises the puncture needle insertion end, connects the bottle end, be provided with the rubber cushion chamber in the lid of the puncture needle insertion end of enclosing cover 1, the rubber cushion intracavity is provided with rubber cushion 2, and rubber cushion chamber one end is communicated with in the lid of enclosing cover 1, the other end in rubber cushion chamber is communicated with the opening 3 on enclosing cover 1 top, and outer cover gab 3 places are provided with foldable handle 4.The junction of foldable handle 4 and enclosing cover 1 is provided with breaks fault trough off with the fingers and thumb.Rubber cushion 2 plays sealing medicinal liquid and fixedly transfusion needle effect.
Be extended with the annular protrusion 5 that snaps in rubber cushion 2 on the tegmental wall of upper end, rubber cushion chamber, rubber cushion 2 corresponding position with it is a circle groove, and the lower end in described rubber cushion chamber is provided with the spacing snap ring 6 of the rubber cushion that is stretched out by tegmental wall.The rubber cushion chamber is two.Enclosing cover 1 outer wall is step-like.Company's bottle end of enclosing cover 1 is provided with double-deck welding anchor ring 7.Each bottom, rubber cushion chamber has more one section than rubber cushion height and reserves annulus, evenly shrink to center position after with the projection fusion by hot melt, after the cooling with elastic mounting in cavity.The outer wall of enclosing cover 1 is provided with detent 8.Enclosing cover 1 can adopt polypropylene, modified polypropene, has very little opening force, with plastic infusion bottle good welds is arranged.Rubber cushion 2 is the isoprene rubber cushion, makes up easily with enclosing cover, and good seal performance, it is big to embrace needle force, and puncture exfoliation rate is low.This composite cover be applicable to the aseptic transfusion fill injection moulding, fill, seal three-in-one plastic infusion bottle.
Upwards pull foldable handle 4 with finger during use, expose rubber cushion 2, puncture needle is inserted in rubber cushion 2 puncturing holes, enter in the transfusion by the transfusion bottle then.Rubber cushion and enclosing cover, transfusion needle closely cooperate, and play sealing and fixedly transfusion needle effect, because rubber cushion 2 puncture faces own are thin, reduce penetration Resistance, reduce rubber cushion 2 puncture exfoliation quantity greatly.This utility model and traditional draw-ring type composite cover technology relatively do not have inner cap, and with rubber cushion puncturing hole diameter increase, thickness changes thinly, effectively reduces rubber cushion puncture exfoliation number, cover top portion foldable handle opening force is littler than draw-ring type composite cover, makes things convenient for medical personnel to use.This composite cover has reduced composite cover pp material and rubber cushion raw material consumption, guarantees that drug safety has reduced cost simultaneously, and safety is higher, and lid is easy to assembly.
By reference to the accompanying drawings this utility model has been carried out exemplary description above; obviously this utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
