摘要
牙膏作为人类生活必不可少的生活用品,销售量巨大,但传统的扁平软管配合人挤压管体的形式使得残余牙膏过多,每年造成的资源浪费以及环境污染十分严重,如何使牙膏管体的膏体被充分挤出,是我们亟须解决的技术问题。本文基于CNABS和DWPI数据库,通过检索、筛选、统计国内外有关牙膏挤出装置的专利申请文献以及对专利申请的年度分布、地域分布以及IPC分布等方面信息的分析,归纳出牙膏挤出装置技术领域重要技术分支的专利技术演进路线。
Toothpaste,as an essential daily necessities of human life,has a huge sales volume.However,the traditional flat tube combined with squeezing tube body by human makes excessive residual toothpaste,which casues serious resource waste and environmental pollution every year.So,how to make the tube body of tooth.paste be fully squeezed is a problem that we urgently need to solve.Based on CNABS and DWPI database,this paper summarizes the patent technology evolution route of the important technology branches in the technology field of toothpaste squeezing device through searching,sifting,counting the patent application literature of toothpaste squeezing device and analyzingthe annual distribution,geographical distribution and IPC distribu.tion of patent applications.
