The invention relates to a bottle cap, in particular to a novel medical freeze-dried bottle stopper, which comprises a bottle stopper of which a center is provided with a round hole, and is characterized in that the periphery of the bottle stopper is uniformly provided with four round vent grooves, an outer wall of the bottle stopper is provided with double wedges, and a neck of the bottle stopper is provided with a 3 DEG guide angle. The novel medical freeze-dried bottle stopper has the advantages of simple structure and convenient use, can ensure that a packaging bottle has good air tightness, has the advantages of good freeze-drying effect and high production efficiency during production and packaging processes of freeze-dried powder injection, is favorable for the quick vacuum aseptic packaging of medicines, and improves the quality of products and the efficiency.
Description
technical field [0001] The invention relates to a bottle cap, in particular to a novel medicinal freeze-dried bottle stopper. Background technique [0002] Existing injections and powder medicines are generally bottled, and especially freeze-dried powder injections are generally bottled according to national pharmaceutical product standards, and sealed with rubber caps for preservation. The production of freeze-dried powder injections is generally to freeze-dry the medicinal liquid containing the active ingredients of the drug and carry out vacuum aseptic packaging, and the production process is generally very long. For example, the production process of a certain product is as follows: first cool down for 2 hours, the temperature drops to -40°C, and maintain this temperature for about 6 hours; start to gradually increase the temperature to 25°C, a vacuum state is required during this process, and it takes about 30-35Pa to maintain a vacuum. It takes about 48 hours; the fre...
