Abstract
The utility model discloses a cylindrical medicinal cork gasket. The cylindrical medicinal cork gasket comprises a cylindrical gasket body, wherein an elastic convex ring is arranged on the edges of the top surface and the bottom surface of the gasket body; the elastic convex rings and the top surface and the bottom surface of the gasket body are concentric; the elastic convex rings are respectively 1.2 mm higher than the top surface and the bottom surface of the gasket body; the top surface and the bottom surface of the gasket body are respectively provided with three acupunctured concave pits; the inner wall of each concave pit has a slope. The cork gasket disclosed by the utility model does not drop crumbs; the sealing performance of the cork gasket with a combination cover and the self-sealing performance are high; moreover, the cost is low.
Description
Technical field:
This utility model relates to a kind of cylindrical filling piece for medical bottle stopper.
Background technology:
Existing bottle stopper for injection pad, though its surface is provided with elasticity flange collar, just a little more than mid portion, during puncture, pad, easily with the pulling and pushing up and down and form upper and lower deformation of draw point, increases penetration Resistance, and then forms exfoliation and pollute medicine, and it is large that gap during deformation and between composite cover becomes, easy-to-leak liquid.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of cylindrical filling piece for medical bottle stopper, and acupuncture is exfoliation not, good with sealing and the self sealss of composite cover, and cost is low.
This utility model technical solution problem adopts following technical scheme:
A kind of cylindrical filling piece for medical bottle stopper, comprise overall cylindrical shim body, end face and bottom edge in described shim body are provided with a circle elasticity flange collar, described elasticity flange collar is concentric with end face and the bottom surface of described shim body, the height of described elasticity flange collar exceeds respectively end face and the bottom surface 1.2mm of shim body, and being provided with separately three acupuncture pits in end face and the bottom surface of described shim body, the inwall of described pit is slope.
Between the end face of described elasticity flange collar and described shim body and bottom surface, be provided with a circle groove, described groove is concentric with described elasticity flange collar.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The outer ring of this utility model bottle stopper pad (elasticity flange collar) exceeds shim body end face and bottom surface 1.2mm, and makes the good airproof performance between bottle stopper pad and composite cover establishing a circle groove between flange collar and body, is difficult for pasting between product, is convenient to pharmaceutical factory cabling; Meanwhile, end face and bottom surface pit inwall are ramped shaped, after acupuncture the self sealss of pin hole good, pad adopts isoprene material to make, acupuncture can exfoliation, can not pollute medicinal liquid; Product size, compared with conventional spacers little (diameter 15.2mm), reduces use cost.
Accompanying drawing explanation:
Fig. 1 is cutaway view of the present utility model; Fig. 2 is front view of the present utility model.
Number in the figure: 1 shim body, 2 flange collars, 3 pits, 4 grooves.
Below pass through the specific embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
The specific embodiment:
Embodiment: in conjunction with Fig. 1-2, the cylindrical filling piece for medical bottle stopper of the present embodiment, comprise overall cylindrical shim body 1, end face and bottom edge in shim body 1 are provided with a circle elasticity flange collar 2, elasticity flange collar 2 is concentric with end face and the bottom surface of shim body, and the height of elasticity flange collar exceeds respectively end face and the bottom surface 1.2mm of shim body, in end face and the bottom surface of shim body 1, be provided with separately three acupuncture pits 3, the inwall of pit 3 is slope.Three pits are one large two little, and each pit is corresponding at end face and the basal surface position of shim body.Between the end face of elasticity flange collar 2 and shim body and bottom surface, be provided with a circle groove 4, and groove is concentric with elasticity flange collar, makes the good airproof performance between bottle stopper pad and composite cover.
