Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of pin hole lid internal fastening type building rubber compound bottle cap.
Background technology
Existing injection bottleneck sealing means has three kinds: the first closes up after utilizing the high temperature melting bottle, and as the production technology of ampoule dress injection, this production technology causes the part medicine rotten under localized hyperthermia's condition easily, thereby influences patient's health; Another kind of sealing means is to select for use aluminium lid or aluminium-plastic cap to add top cement plug to finish by gland, but after the aluminium lid processing aluminum bits is often arranged, and easy contaminated environment and medicine make the visible foreign matters of medicine defective in the gland process; The composite cover that also has a kind of similar plastic cement, but this composite cover does not carry out sterility protection to the drawn needle mouth, must carry out the ethanol secondary sterilization when using clinically, makes operation cumbersome.
Summary of the invention
The purpose of this utility model provides a kind of pin hole lid internal fastening type building rubber compound bottle cap, and is simple in structure, can realize aseptic assembly operation, low cost of manufacture, and good sealing effect.
The technical scheme that this utility model adopted is, a kind of pin hole lid internal fastening type building rubber compound bottle cap, comprise pin hole lid, plug, bottle cap body composition, wherein plug covers on the bottleneck of medicine bottle, the inner face of bottle cap body covers on the plug, and the surface of internal cavity of bottle cap body is provided with lock dog, and lock dog and bottleneck are along being connected by buckle, the upper surface of bottle cap body has pin hole, is coated with the pin hole lid on the pin hole.
Combined bottle cap of the present utility model, its feature also is:
Described pin hole is covered with concentric annulus boss, and the excircle of annulus boss is provided with groove.
The excircle of described plug is provided with step, the lower surface of plug is provided with the annulus convex tendon near excircle, the average diameter of annulus convex tendon is consistent with the average diameter of bottleneck, and the lower surface of plug is provided with the taper round platform, and the maximum outside diameter of taper round platform is greater than bottleneck diameter.
The internal diameter of the pin hole of described bottle cap body is identical with the external diameter of annulus boss, is provided with annular boss in the pin hole, and annular boss matches with groove; The inner chamber epimere of bottle cap body is provided with convex tendon, convex tendon and step clamping mutually.
The beneficial effect of this utility model device is, and is simple in structure, can realize aseptic assembly operation, low cost of manufacture, and good sealing effect.
