Abstract
The utility model relates to a rubber freeze-dried diaphragm bottle cork for medicine, which is composed of a bottle cork crown part and a neck part, wherein the neck part is composed of a first-class cork neck and a second-class cork neck, and a transition table top is formed between the first-class cork neck and the second-class cork neck. The outer surfaces of the first-class cork neck and the second-class cork neck are covered by inactive membrane materials, and the first-class cork neck is provided with a vent groove. The rubber freeze-dried diaphragm bottle cork for medicine is characterized in that the neck part is composed of the first-class cork neck and the second-class cork neck, the transition table top is formed between the first-class cork neck and the second-class cork neck, and the first-class cork neck is provided with the vent groove as moisture sublimation channel; the outer surfaces of the first-class cork neck and the second-class cork neck are covered by the inactive membrane materials, so that the isolation of a bottle cork rubber matrix and bottled medicine keeps a good compatibility effect; and the end surface of the rubber freeze-dried bottle cork crown part touching with a bottle opening has no higher molecular inactive membrane material, keeping the good sealing effect of the sealing end surface of the bottle cork crown part and the end surface of the medicine bottle opening.
Description
Technical field
This utility model relates to a kind of pharmaceutical packing container bottle stopper, is specifically related to a kind of pharmaceutical rubber lyophilizing septum bottles plug that is used for the splendid attire lyophilized injectable powder.
Background technology
Present domestic common medical rubber bottle stopper for lyophilized powder formulation, the technology of production, formula technique ratio are easier to grasp; But because in design during rubber compounding, consider to satisfy the indexs such as physical property, mechanical performance of bottle stopper, just must add the number of chemical element; The rubber bottle stopper for lyophilized powder formulation outer surface of cervical region in use directly contacts with bottled medicine, so the chemical constituent of bottle stopper inside and medicine produce chemical reaction and cause occurring insurmountable problem such as the compatibility.
Summary of the invention
The purpose of this utility model is that a kind of pharmaceutical rubber lyophilizing septum bottles plug that cervical region does not directly contact with bottled medicine of filling in will be provided.
The purpose of this utility model is achieved in that a kind of pharmaceutical rubber lyophilizing septum bottles plug, constitute by bottle stopper bizet and cervical region, cervical region is made of one-level plug neck and secondary plug neck, form an excessive table top between one-level plug neck and the secondary plug neck, one-level plug neck and secondary plug neck outer surface are coated with the inert coating material, have air channel on the one-level plug neck.Described air channel is one or two.Two air channels point-blank.
The pharmaceutical rubber lyophilizing septum bottles plug that this utility model provides, its cervical region is made of one-level plug neck and secondary plug neck, form an excessive table top between one-level plug neck and the secondary plug neck and on one-level plug neck, air channel be set, when the splendid attire lyophilized medication as the passage of water sublimed; Adopt two air channels point-blank, can accelerate water sublimed speed; One-level plug neck and secondary plug neck outer surface are coated with the inert coating material, make the isolation of bottle stopper rubber matrix and bottled medicine, have kept good compatibility effect; The end face that rubber bottle stopper for lyophilized powder formulation bizet contacts with bottleneck does not have macromolecule inert coating material, has kept the excellent sealing effect of bottle stopper coronal seal end face and medicine bottleneck end face.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation that the utlity model has an air channel.
Fig. 2 is that the A-A of Fig. 1 is to view.
Fig. 3 is the structural representation that the utlity model has two air channels.
Fig. 4 is that the B-B of Fig. 3 is to view.
The specific embodiment
As depicted in figs. 1 and 2, this utility model is made of bottle stopper bizet 1 and cervical region, cervical region is made of one-level plug neck 4 and secondary plug neck 2, form an excessive table top 5 between one-level plug neck 4 and the secondary plug neck 2, one-level plug neck 4 and secondary plug neck 2 outer surfaces are coated with inert coating material 3, have air channel 6 on the one-level plug neck 4.
As shown in Figure 3 and Figure 4, have two air channels 6 point-blank on the one-level plug neck 4.
This utility model in use, injectable sterile powder is divided in the bottle with lyophilization original liquid or freeze dried powder, spacing one-level plug neck 4 with bottle stopper by excessive table top 5 covers in medicine container, this moment, medicine container was in semitight, the gas that freeze-dried drug distillation produces is discharged by air channel 6, after lyophilizing is finished bottle stopper is compressed and finishes sealing.The end face 7 no macromolecule inert coating materials that rubber bottle stopper for lyophilized powder formulation bizet 1 contacts with bottleneck, the excellent sealing effect that has kept bottle stopper coronal seal end face and medicine bottleneck end face, one-level plug neck 4 and secondary plug neck 2 outer surfaces are coated with inert coating material 3, make the isolation of bottle stopper rubber matrix and bottled medicine, kept the good compatibility.
