    • PROBLEM TO BE SOLVED: To stably detachably engage a container body and a cap while improving a productivity.SOLUTION: A leading end portion 10 of a tubular container body 1 is provided with one or more projection portion 26 on an outer peripheral surface, a hole 27 making inner and outer sides of a tube communicate with each other in a rear side in an axial direction of the projection portion 26, and an expanded portion 12 expanded such that an outer diameter within the tube is equal to or more than an outer diameter of the projection portion 26 and running to a rear side in a rear side in an axial direction of the hole 27. An inner peripheral surface of a cap 50 is provided with an annular projection 52 detachably engaging with the projection portion 26 in an axial direction. The projection portion 26 securely climbs over the annular projection 52 for its flexibility in a diametrical direction by the hole 27, the container body 1 and the cap 50 can be detachably engaged by inserting the leading end portion 10 of the container body 1 into an opening 51 of the cap 50. The cosmetic material container can be easily manufactured without forcibly drawing the inner and outer molds in an axial direction, without using cut molds, and without using a press machine, focusing attention on the fact that the hole 27 can be formed by making parts of an inner mold and an outer mold abut on each other when forming the container body 1 using the inner mold and the outer mold.
    • 要解决的问题:为了稳定地可拆卸地接合容器主体和盖,同时提高生产率。 解决方案:管状容器主体1的前端部10在外周面上设置有一个或多个突出部26,使得管的内侧和外侧的孔27在后侧相互连通 在突出部分26的轴向方向上,并且扩张部分12膨胀,使得管内的外径等于或大于突出部分26的外径并且在后侧的后侧延伸 盖50的内周面设置有沿轴向方向与突出部26可拆卸地接合的环形突起52。 突出部26通过孔27在径向方向上可靠地爬过环形突起52,容器主体1和盖50可以通过将容器主体1的前端部10插入开口中而可拆卸地接合 可以容易地制造化妆品容器,而不使用切割模具而不使用切割模具在轴向方向上强制拉伸内模和外模,并且不使用冲压机,注意孔27可以是 通过在使用内模和外模形成容器主体1时,通过使内模和外模的部件彼此抵接而形成。 版权所有(C)2013,JPO&INPIT
