PURPOSE: To reduce the number of operations by the manufacture of a compressively deformable container and arrange a recess part of a top panel so as to provide a downward outflow direction of liquid chemicals to prevent the scattering thereof.

CONSTITUTION: Areservoir part 11 and a pipe 12 are formed integrally, the top end of the pipe 12 is closed with a top panel 12a having a recess part formed in its inner surface add the discharge holes 12b open to the outer side face are provided. When a container B is deformed, liquid chemicals are allowed to flow out into the reservoir part 11 through the discharge holes 12b to make the weighing thereof possible in terms of the content volume of the reservoir part 11 as a unit.
