Patent ID: 8870005

Claim:
A chemical bottle for supplying a chemical to an endoscope cleaning/disinfecting apparatus, the endoscope cleaning/disinfecting apparatus having a limit switch, the chemical bottle comprising: a storing section that stores the chemical and that includes an upper surface, a bottom surface facing the upper surface, a first side face that connects the upper surface and the bottom surface, and a second side face that connects the upper surface and the bottom surface and that faces the first side face; an opening that is provided in the upper surface and whose center is disposed further to a side of the second side face than a center of the upper surface; a concave portion that is formed in the first side face, the concave portion causing the limit switch to be closed by the upper surface and to be opened in the concave portion when the chemical bottle is moved from the upper surface towards the bottom surface; and a convex portion formed by a surface of the concave portion on a side close to the upper surface, the convex portion having a weaker mechanical strength than another area of the first side face; wherein: the convex portion is irreversibly deformed or broken from the bottom surface side towards the upper surface side by the limit switch when the limit switch moves in the concave portion toward the upper surface side and contacts the surface of the convex portion.
