Abstract
The utility model relates to a combined cover for a plastic infusion bottle. The combined cover is simple in structure and novel and is mainly composed of an inner cover, an outer cover and a rubber gasket. The combined cover is characterized in that a cylindrical or oval fixing sleeve is arranged in the outer cover, the rubber gasket is positioned in the outer cover, and an annular protrusion at the upper portion of the inner cover can press the gasket tightly to guarantee sealing. When the combined cover is used, a pull ring of the outer cover is slightly pulled open. The combined cover has the advantages of being simple in structure, convenient to open, strong in practicability and especially suitable for medical plastic infusion products.
Description
Technical field
This utility model plastic infusion bottle belongs to the medical packaging Material Field with composite cover, is specifically related to the bottle cap that a kind of plastic infusion bottle is used.
Background technology
The similar bottle cap that generally uses is in the market required great effort during use for breaking Easy-folding or draw-ring type into two with one's hands, and the rubber sheet gasket size is larger, and the phenomenon of leakage appears in clinical use sometimes.It is also relatively bigger than normal to add the inward upper cover size, and the relatively poor weldering leakage phenomenon that is prone to of sealing retentivity is also held in welding during production, exists certain clinical risk, and the raw material of relative usage is also more in addition, causes production cost higher.
The utility model content
The purpose of this utility model is the defective that will solve and overcome above-mentioned prior art, a kind of draw-ring type plastic infusion bottle composite cover is provided, this bottle cap adopts matter with, low-cost raw material and novel internal structure, make its good looking appearance, technique is simple, unlatching is convenient, is the plastic infusion bottle cap that a kind of seal is strong, production cost is low, practicality is stronger.
This utility model adopts following technical proposals, this plastic infusion bottle composite cover, mainly formed by inner cap (1-2), enclosing cover (1-8) and rubber sheet gasket (1-1) three parts, it is characterized in that: described enclosing cover (1-8) internal upper part has the fixed cover (1-5) of rubber sheet gasket, can be with rubber sheet gasket (1-1) close positioning in its center; Described inner cap (1-2) central upper portion has a circular protrusion (1-4), circular protrusion (1-4) closely cooperates with rubber sheet gasket (1-1), fixed cover (1-5), the center of circular protrusion (1-4) is thin layer, is the site of puncture of plastics pin or draw point.The figure of facing of the fixed cover (1-5) of rubber sheet gasket is circle or oval in the enclosing cover, and the longitudinal section is rectangle or convex, and the annular edge of a knife (1-3) triangular in shape is arranged at its fixed cover (1-5) top.
Compared with prior art, the beneficial effects of the utility model are: by the change to this composite cover structure, shim size is reduced, cost is descended greatly, pad fixed cover in the enclosing cover has then strengthened the retentivity of its airtight performance and transfusion device greatly, and its practicality is strengthened.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
1-1 is that rubber sheet gasket, 1-2 are that inner cap, 1-3 are that the leg-of-mutton annular edge of a knife, 1-4 are that circular protrusion, 1-5 are that fixed cover, 1-6 are that enclosing cover draw ring, 1-7 are that thin layer, 1-8 are enclosing cover.
The specific embodiment
This utility model is a kind of plastic infusion bottle composite cover of novel structure, be comprised of inner cap (1-2), enclosing cover (1-8) and rubber sheet gasket (1-1) three parts, inner cap (1-2) and enclosing cover (1-8) adopt convex-concave to clamp mode and make up.Circular or oval-shaped rubber sheet gasket fixed cover (1-5) are arranged in enclosing cover (1-8) top, rubber sheet gasket (1-1) is placed fixed cover (1-5).Inner cap (1-2) central upper portion has a circular protrusion (1-4), circular projection is pressed on rubber sheet gasket (1-1) in the fixed cover (1-5) it is closely cooperated, the center of circular protrusion (1-4) is thin layer (1-7), is transfusion device plastics pin or puncture of steel needles.The annular edge of a knife (1-3) triangular in shape is arranged at fixed cover top, is easy to enclosing cover draw ring (1-6) and easily pulls open.
During use, namely expose rubber sheet gasket (1-1) after enclosing cover draw ring (1-6) pulled open, again plastics pin or puncture of steel needles rubber sheet gasket (1-1) center are got final product.
