Abstract
The invention discloses a plastic bottle cap of an infusion bottle. The plastic bottle cap of the infusion bottle comprises an outer cover and a rubber mat; the outer cover comprises an upper cylinder and a lower cylinder; the rubber mat is clamped in the upper cylinder of the outer cover; a circle of bulges are formed on the inner wall of the upper cylinder; and a circle of grooves which are tightly matched with the bulges are formed on the outer side of the rubber mat. The plastic bottle cap of the infusion bottle is opened conveniently; the exfoliation rate of rubber mat puncture is low; a structure is simple, the plastic bottle cap of the infusion bottle is convenient to use and manufacture; manufacturing cost is reduced; and the yield of a product is increased at the same time.
Description
Technical field
The present invention relates to the transfusion medicine packing field, relate in particular to the supporting composite cover of plastic container for infusion.
Background technology
High-capacity injection is directly to import human vein at present, because its drug effect is rapid, uses extensively in medical treatment, and intravenous injection keeps away unavoidable needs and uses infusion bottle in a large number, and infusion solutions plastics packaging material application at present is general, 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 in this bottle cap, when transfusion needle inserts, produces exfoliation when rubber cushion and inner cap puncture and can bring in the transfusion, cause the transfusion foreign body, these exfoliations even can stop up pin hole causing transfusion to interrupt, this Bottle cap structure complexity, product cost is higher.
Summary of the invention
The technical problem to be solved in the present invention is to realize a kind ofly can not producing exfoliation after transfusion needle inserts bottle cap, and the while is simple in structure, and production cost is low, the infusion bottle plastic bottle closure that security performance is higher.
To achieve these goals, the technical solution used in the present invention is: a kind of infusion bottle plastic bottle closure, comprise enclosing cover, rubber cushion, described enclosing cover is divided into cylinder and lower prop, described rubber cushion is stuck on the enclosing cover in the cylinder, the described inboard wall of cylinder of going up is provided with a circle projection, and the described rubber cushion outside is provided with a circle and protruding close-fitting groove.
Described rubber cushion is provided with two puncturing holes, and rubber cushion is the cambered surface that caves inward towards lower prop one side.
The lower prop of described enclosing cover is placed in outside the infusion bottle bottleneck, and the internal diameter of lower prop is greater than last cylinder internal diameter.
The described cylinder top cover medial surface of going up is provided with the easy kerve of a circle, and the top cover lateral surface is provided with draw ring, and the connecting portion of described draw ring and top cover is in easy kerve.
Described easy-to-draw slot cross-section is round rectangle.
The described outside of going up the easy kerve of cylinder is provided with a circle fixed lobe.
Described rubber cushion is provided with the fastening projection of a circle towards top cover one lateral edge, described fastening projection is stuck in the gap of fixed lobe and last inboard wall of cylinder.
Described lower prop is circumferentially with reinforcement along inwall.
Described rubber cushion and last cylinder top cover shape are round rectangle.
The invention has the advantages that this infusion bottle plastic bottle closure opens conveniently, rubber cushion puncture exfoliation rate is low, and simple in structure, uses easily manufacturedly, has reduced manufacturing cost, has improved the yield rate of product simultaneously.

The specific embodiment
Referring to Fig. 1 to 6 as can be known the present invention compare with the bottle cap of prior art, reduced interior cover, infusion bottle plastic bottle closure of the present invention is made up of enclosing cover 1 and rubber cushion 2, wherein enclosing cover 1 is that integral type is injection molded, being provided with two different step bodies constitutes, be respectively cylinder 7 and lower prop 8, lower prop 8 is connected with infusion bottle 12 during use, it is placed in, and infusion bottle 12 bottlenecks are outer to be welded mutually with infusion bottle 12, and last cylinder 7 is provided with top cover and cylinder, is provided with rubber cushion 2 in the cylinder, its inwall and rubber cushion 2 fit tightly, rubber cushion 2 plays sealing medicinal liquid and fixedly transfusion needle effect, for fixing rubber cushion 2, is provided with one at last cylinder 7 inwalls and encloses protruding 3, enclose groove 10 in the arranged outside one of rubber cushion 2 simultaneously, during assembling, projection 3 is corresponding with groove 10 positions, and projection 3 embeds in the groove 10 and closely cooperates.The internal diameter of the lower prop 8 of enclosing cover 1 is greater than the internal diameter of last cylinder 7, and the top cover shape of last cylinder 7 is generally round rectangle, and the shape of rubber cushion 2 adapts with it.
The top cover medial surface of cylinder 7 is provided with the easy kerve 4 of a circle on the enclosing cover 1, these easy kerve 4 cross sections are round rectangle, to compare opening force littler with the easy kerve of existing composite cover spiral, the top cover lateral surface of last cylinder 7 is provided with draw ring 5, draw ring 5 encloses in the circle of easy kerve 4 one with the connecting portion of top cover, be close to easy kerve 4, the outside of the easy kerve 4 of last cylinder 7 also is provided with a circle fixed lobe 6, be provided with a circle fastening protruding 11 towards top cover one lateral edge at rubber cushion 2 simultaneously, there is the gap between fixed lobe 6 and last cylinder 7 inwalls, during assembling, fastening protruding 11 embed in this gap, to reach the better fixedly effect of rubber cushion 2, rubber cushion 2 is provided with two puncturing holes, and is symmetrical arranged, puncturing hole is that both sides cave inward and the position thin with respect to rubber cushion 2 other parts, be the cambered surface that caves inward at rubber cushion 2 towards lower prop 8 one sides, this cambered surface is used for the applying of sealing with infusion bottle 12 upper ends, and Ao Xian arcuate structure makes and certain support force is provided can for when transfusion needle inserts rubber cushion 2 rubber cushion 2 simultaneously.Be circumferentially with a circle reinforcement 9 at enclosing cover 1 lower prop 8 along inwall, this reinforcement 9 plays the effect of strengthening enclosing cover 1 lower prop Final 8 degree when assembling.
The enclosing cover 1 of infusion bottle plastic bottle closure of the present invention is that certain elastic modified polypropene is made, has very little opening force, with plastic infusion bottle 12 good welds is arranged.Described rubber cushion 2 is than the thin thickness of existing rubber cushion, and its material is the isoprene rubber cushion, make up easily with enclosing cover 1, and good seal performance, it is big to embrace needle force, and puncture exfoliation rate is low.With pointing the draw ring 5 that catches on the enclosing cover 1, open easy kerve 4 during use, can expose rubber cushion 2, transfusion needle is inserted rubber cushion 2 infusion holes, pass the transfusion bottle again and enter in the transfusion.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
