Abstract
The utility model discloses a diaphragm rubber stopper for injection liquid, which comprises a crown portion and a neck portion, wherein the outer surfaced of a stopper portion is covered with a polymer inertia diaphragm, and the upper portion of a sealing end surface of the crown portion is covered with a polymer inertia diaphragm. Just a part of the sealing end surface of the crown portion is covered with the inertia diaphragm beside the neck portion which is completely covered with the inertia diaphragm in the diaphragm rubber stopper for injection liquid, thereby keeping excellent compatibility effect, and also keeping excellent sealing effect of the sealing end surface of the crown portion of the stopper and an end surface of a drug bottle port.
Description
Technical field
This utility model relates to a kind of pharmaceutical bottle closure of rubber, is specifically related to a kind of injection diaphragm rubber bottle stopper.
Background technology
Because the very big difference of medicine liquid preparation and powder formulation, liquid preparation is stronger than the penetration of powder formulation, liquid preparation has more increased the infiltration and the anti-flow phenomenon of liquid preparation under the high temperature sterilize environment in addition, the overlay film height of common medical diaphragm of rubber bottle stopper is shorter, the plug neck portion rubber body surface of overlay film does not contact with medicine, will cause compatibility risk.
Present domestic common pharmaceutical injection diaphragm rubber bottle stopper, overlay film height all in plug neck Lower Half, can not reach the specification requirement of liquid preparation fully, particularly require higher Chinese medicine liquid adaptability not strong to preparation technique.
Summary of the invention
The purpose of this utility model provides the consistency problem that a kind of rubber matrix that solves bottle stopper plug neck and bottling liquid preparation medicine directly contact generation, the injection diaphragm rubber bottle stopper of safety and reliability.
The purpose of this utility model is achieved in that kind of an injection diaphragm rubber bottle stopper, and bottle stopper is made up of bizet and cervical region, is coated with macromolecule inertia barrier film in exterior, is coated with macromolecule inertia barrier film on the seal face top of bizet.Being coated with the membranous width of macromolecule inertia on the seal face of bizet is the 1/3-1/2 of seal face width.
The injection diaphragm rubber bottle stopper that this utility model provides, except that cervical region covers the inertia barrier film fully, the seal face of bizet just part is coated with the inertia barrier film, has both kept good compatibility effect, has kept the excellent sealing effect of bottle stopper coronal seal end face and medicine bottleneck end face again.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sketch map that this utility model institute glass bottle cooperates.
The specific embodiment
As shown in Figure 1, the bottle stopper that this utility model provides is made up of bizet 1 and cervical region 2, and 2 outer surfaces are coated with macromolecule inertia barrier film 3 in the piston part, is coated with macromolecule inertia barrier film 3 on seal face 6 tops of bizet 3.The width that is coated with macromolecule inertia barrier film 3 on the seal face 6 of bizet 1 is the 1/3-1/2 of seal face 6 width.
As shown in Figure 2, when this utility model used, bottle stopper was packed in the glass bottle 4, add a cover aluminium-plastic cap 5 on the bottle stopper, when aluminium-plastic cap 5 compressed, seal face 6 pressurizeds produced deformation, guaranteed the sealing of sloping bottle 4, macromolecule inertia barrier film 3 has ensured the compatibility of cervical region 2 with glass bottle 4 inner liquid medicines.
Claims (2)
1. injection diaphragm rubber bottle stopper, bottle stopper is made up of bizet (1) and cervical region (2), it is characterized in that: be coated with macromolecule inertia barrier film (3) at cervical region (2) outer surface, be coated with macromolecule inertia barrier film (3) on seal face (6) top of bizet (3).
