摘要

The case has two external case parts (300, 300a) that are disassembled and assembled, where the external case parts protect an internal case (100) that is in form of tubes on which an airless pump (200) is assembled. An injection tube (120) is assembled by thermofusion on an upper part of a sachet (110), and comprises a connection pipe connected at a level of an external periphery of the case. The airless pump is assembled in a control chamber (320) of the external case parts, and performs pumping action when the pump is supported in the control chamber.
