Abstract (en)
A free-form container (30) with follow-up piston (33) includes a double-wall body defining an internal volume for containing a fluid, a top cover (40) connected to an open upper end of the double-wall body, a fluid dispenser head (50) mounted to and projected from the top cover (40), and a bottom cover (60) seal an open lower end of the double-wall body. The double-wall body includes a cylindrical inner wall (31) defining a fully round inner wall surface and a free-form outer wall (32) integrally formed at an outer side of the inner wall (31). A follow-up piston (33) is mounted in the cylindrical inner wall (31) to face toward the fluid dispenser head (50). A vent hole (61) is formed on the bottom cover (60) to communicate an inner space of the inner wall (31) with external air. The outer wall (32) may have differently designed appearances to attract more consumers without affecting the operation of the follow-up piston (33) in the cylindrical inner wall (31).
