Description
技术领域
本发明涉及真空瓶，是一种抗菌高刚性八边形双层真空瓶及其制备方法。
背景技术
真空瓶是指一种能使气体与外界温度隔绝的容器或隔绝外部细菌的容器，市场销售的真空瓶是由一个圆柱体成椭圆体容器加一个安置底部的活塞组成。其工作原理是用弹簧的收缩力，且不让空气进入瓶中，造成真空状态，而利用大气压力来推动瓶底的活塞前进。现有真空瓶应用于日化包装护肤品中，现市场上的真空瓶基本都是泵结构出液，而在平时携带时为防止漏液在其内盖与压盖之间设有防漏垫片起到携带方便安全的作用。现有一些瓶体设有内外瓶结构，如中国专利文献中披露的申请号201820338352.1，授权公告日2018.10.12，实用新型名称“一种真空瓶”；再如中国专利文献中披露的申请号201720477573.2，授权公告日2018.01.09，实用新型名称“圆封闭式真空瓶”；但上述产品和同类产品较少能采用多边形瓶体结构，现市场上的真空瓶几乎为圆形或规则体，并且较难自动化生产装配。
发明内容
为克服上述不足，本发明的目的是向本领域提供一种抗菌高刚性八边形双层真空瓶及其制备方法，使其解决现有同类产品外形结构形式单一，生产装配较为不便，部件较难采用抗菌高刚性材料生产制备的技术问题。其目的是通过如下技术方案实现的。
一种抗菌高刚性八边形双层真空瓶，该真空瓶的外瓶与内瓶套合，内瓶的瓶口伸出外瓶设有大圈，泵芯的阀杆伸出大圈和内瓶，阀杆设有头帽，内瓶内设有大活塞，大活塞与内瓶的内壁相抵密封；其结构设计要点是所述内瓶的瓶身呈圆柱形，外瓶的瓶身呈八面形柱体，即长方体的外瓶周面端角处分别设有倒角边，外瓶的一侧底部设有开口，外瓶的另一侧顶面设有孔口，外瓶的孔口处内径至少一侧设有定位槽，内瓶的外螺纹下方设有对应的定位筋，以及对称设置的扣位筋，内瓶的外螺纹伸出外瓶的孔口，内瓶的定位筋套入外瓶的定位槽，内瓶的扣位筋与外瓶的孔口扣合，大圈一侧的内螺纹与内瓶的外螺纹旋紧，外瓶的孔口处端面夹持固定于大圈与内瓶之间，泵芯通过内塞盖夹持固定于大圈的内孔与内瓶的瓶口之间，连接处的内瓶瓶口设有PE覆膜垫片，泵芯伸出内塞盖的阀杆与头帽的进液孔外径圈筋扣合，头帽的进液孔外径圈环套入大圈顶部的圈槽内；外瓶的底部开口内径设有内圈径，外瓶的内圈径与底盖的圈径槽扣合并超声熔合，底盖的圈径槽内侧设有两两对称设置并凸起的筋条，两侧对称的两条筋条之间分别设有间隙，内瓶底部的开口外径设有凸起的筋块，内瓶的筋块套入底盖筋条之间的间隙，内瓶底部的开口与底盖相抵密封。从而内瓶通过外瓶的底部套入的同时，底盖与外瓶的底部瓶口通过超声熔合密封，内瓶的底部瓶口与底盖相抵密封扣合。
所述大圈的内螺纹处外径设有凸起的扣点，大圈扣点对应的外罩盖口内径设有扣位槽，大圈的扣点与内盖的扣位槽扣合。从而便于外罩与大圈扣合固定。
所述泵芯的内塞盖与泵体的泵口外径扣合，扣合处的内塞盖外径设有向外延伸的盖裙圈，内塞盖中心孔的内塞侧伸入泵体内，泵体的泵口处内塞盖与阀杆的孔口外径之间设有弹簧，阀杆通过内塞盖伸出泵体，泵体内的阀杆一端与泵体内的阀针一端套合，套合处下方的阀针外径设有活塞，泵体内进液一端泵体孔口处设有弹套。上述为泵芯结构的具体实施例。
