Abstract

本实用新型公开了一种冷冻干燥用胶塞,包括冠部和颈部,颈部上设有通气槽,颈部设有防跳筋,防跳筋处直径大于颈部直径。本实用新型在胶塞颈部设有防跳筋,防跳筋的直径大于胶塞颈部的直径,当冻干完成后,给胶塞一个压力,胶塞进入瓶口,防跳筋也进入瓶口,防跳筋的直径也大于瓶口的内径,故防跳筋卡在瓶口内部,防止了跳塞现象的发生。在胶塞背部设有防粘连凸起,当胶塞在输送带上的时候,防粘连凸起使胶塞与传送带之间存在一个间隙,间隙内有气体,可防止胶塞与输送带的粘连,同理也防止胶塞之间的粘连。

Description

一种冷冻干燥用胶塞 
技术领域
本实用新型属于医药包装领域,具体涉及一种瓶塞。 
背景技术
现有冻干粉针剂的生产一般是将含有药物有效成分的药液冻干后进行真空无菌包装,其生产过程长,在冻干过程中既要将药瓶加塞、保持无菌,又不能使瓶塞密封太严。现有冷冻干燥胶塞有多种,如申请号为“200820191056.X”、授权公告号为“CN201263791Y”、名称为“新型药用冻干瓶塞”的实用新型专利所述,现有的瓶塞在使用过程中存在下述缺点:1.在工厂输送过程中,由于瓶塞是橡胶材质,瓶塞在受热或者受到外界压力时易粘连在输送带上,或者多个瓶塞之间发生粘连;2.由于橡胶材质的胶塞表面光滑,当胶塞与瓶体组装完毕后,受瓶体内外压力大小不同的影响,胶塞易从瓶口弹跳出来(即跳塞)。 
实用新型内容
本实用新型要解决的技术问题是冷冻干燥用胶塞易发生粘连、胶塞易从瓶口弹出,提供一种不容易发生粘连、组装时胶塞不易从瓶口弹出的冷冻干燥用胶塞。 
本实用新型的技术方案是以下述方式实现的: 
一种冷冻干燥用胶塞,包括冠部和颈部,颈部设有防跳筋,防跳筋处直径大于颈部直径,颈部上设有通气槽,通气槽位于圆柱体颈部的中间,把颈部分为横截面为弓形的两部分,通气槽的上部是位于颈部内的一个凹槽,通气槽的顶部高于防跳筋的上边缘。 
上述冠部设有防粘连凸起。 
本实用新型在胶塞颈部设有防跳筋,防跳筋的直径大于胶塞颈部的直径,当冻干完成后,给胶塞一个压力,胶塞进入瓶口,防跳筋也进入瓶口,防跳筋的直径也大于瓶口的内径,故防跳筋卡在瓶口内部,防止了跳塞现象的发生。 在胶塞背部设有防粘连凸起,当胶塞在输送带上的时候,防粘连凸起使胶塞与传送带之间存在一个间隙,间隙内有气体,可防止胶塞与输送带的粘连,同理也防止胶塞之间的粘连。 
附图说明
图1是本实用新型的结构示意图; 
图2是图1的仰视示意图; 
图3是图1的俯视示意图。 
具体实施方式
实施例1 
如图1、图2所示,本实用新型包括冠部1和颈部2,颈部2设有防跳筋4,防跳筋4处直径大于颈部2直径,颈部2上设有通气槽3,通气槽3位于圆柱体颈部2的中间,把颈部2分为横截面为弓形的两部分,通气槽3的上部是位于颈部2内的一个凹槽,通气槽3的顶部高于防跳筋4的上边缘。 
本实用新型使用过程如下:在冻干粉针剂生产过程中,先将药瓶处于半压塞状态(通气槽3一部分在药瓶内,一部分露在药瓶外面),水蒸气可以从通气槽3处蒸发掉,冻干完成后,直接将瓶塞压紧即可实现全压塞(完全密封),实现了快速真空无菌包装,且冻干效果比较好。 
实施例2 
如图3所示,所述冠部1设有防粘连凸起5,其他结构同实施例1。
