具体的,所述吸气剂5与所述隔层上盖1相固定。采用的吸气剂5为铬,通过将铬放到金属网状套里面,然后将金属网状套焊接在隔层上盖1上。
进一步的,所述筒体2的底部开设有一个凹陷形的抽气孔12,所述抽气孔12通过钎焊剂覆盖以将真空腔体11密封。将筒体2内的空气经抽气孔12抽掉,然后用钎焊剂将抽气孔12堵上。
进一步的,所述抽气孔12的宽度为0.5mm,内凹的深度为5mm。
本发明另一具体实施例为:一种杯盖真空隔层结构的制作方法,包括以下步骤,

S4、将筒体放到高温炉进行高温加热,激活半真空腔体内的吸气剂,将半真空腔体内的空气进行氧化吸收,形成一个全真空腔体;
S5、在隔层上盖铺设一层塑料上盖层,在筒体的外表面包裹一层塑料下盖层,然后将塑料上盖层与塑料下盖层一体成型,以将隔层上盖与筒体完全包裹,所述塑料上盖层竖直向下沿着塑料下盖层延伸出延伸部,所述延伸部与塑料下盖层形成杯口槽,所述塑料下盖层横向延伸出凸出部,所述凸出部与延伸部之间形成卡口。所述塑料上盖层延伸出来的延伸部以及塑料下盖层横向延伸出的凸出部可通过注塑形成。
