Abstract
The utility model discloses a freeze drying rubber plug with three openings, which comprises a crown part and a neck part; three vent grooves are arranged on the neck part, and protruded teeth are arranged on the side wall of the neck part. As three vent grooves are arranged on the neck part of the rubber plug, the moisture in liquid medicine can be quickly discharged through the vent grooves in a freeze drying process, and the exhaust performance and the freeze drying effect of the rubber plug are excellent. Additionally, a sealing matching surface is arranged at the root of the rubber plug with a diameter greater than that of the neck and the sealing matching surface is directly contacted with a bottle opening in storage and transportation process, therefore, the sealing performance is excellent.
Description
Technical field
This utility model belongs to the medical packaging field, is specifically related to a kind of bottle stopper.
Background technology
The production of existing lyophilized injectable powder generally is to carry out the sterile vacuum packing after containing the medicinal liquid lyophilizing of effective ingredient, its production process is generally very long, should keep aseptic with on the medicine bottle stopper in freeze-drying process, moisture can not make the bottle stopper sealing too tight again, in order to avoid can not evaporate rapidly in the medicinal liquid.Can keep aseptic sealing again not too tight in the freeze-drying process in order to be implemented in the prior art, maneuver commonly used is at the plug cervical region one or two air channels to be set, but in some cases, one, two air channel exhaust effect in freeze-drying process is still bad; And some bottle stopper poor sealing in storage process.
The utility model content
Purpose to be solved in the utility model is at above-mentioned the deficiencies in the prior art, provides three good opening lyophilization plugs of a kind of freeze-drying process venting quality.
The technical solution of the utility model realizes in the following manner:
A kind of three opening lyophilization plugs comprise bizet and cervical region, and cervical region is provided with air channel, and the sidewall of cervical region is provided with double wedge, and described air channel is three.
Described cervical region root is provided with the face of being sealed and matched.
This utility model is provided with three air channels at the plug cervical region, and in the freeze-drying process, the moisture in the medicinal liquid can be discharged by air channel rapidly, and the venting quality of plug is relatively good, and lyophilizing is effective.In addition, be provided with the face of being sealed and matched at the root of plug, the diameter of the face that is sealed and matched is greater than the diameter of cervical region, and in storage and transport process, the face that is sealed and matched directly contacts with bottleneck, and sealing is better.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment 1;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic;
Fig. 3 is the structural representation of this utility model embodiment 2;
Fig. 4 is that the B-B of Fig. 3 is to cross-sectional schematic.
The specific embodiment
As depicted in figs. 1 and 2, this utility model comprises bizet 5 and cervical region 2, and cervical region 2 is provided with air channel 3, and the sidewall of cervical region 2 is provided with double wedge 1, and described air channel 3 is three.
This utility model use is as follows: in the lyophilized injectable powder production process, earlier medicine bottle is in half tamponade state (air channel 3 parts are in medicine bottle, and a part is exposed at the medicine bottle outside), steam can evaporate from air channel 3, after lyophilizing is intact, directly bottle stopper is compressed.
As shown in Figure 3 and Figure 4, described cervical region root is provided with the face of being sealed and matched 4, and the cervical region root is meant the position that cervical region 2 and bizet 5 join.Other structures are with embodiment 1.The face 4 that is sealed and matched contacts with the medicine bottle bottleneck, and sealing is relatively good, has realized the fast vacuum aseptic packaging.
