Liquid accommodating container

A liquid accommodating container, comprising:

• a member including:
• a first region including an accommodating reservoir, the accommodating reservoir being configured to accommodate, in a hermetically closed state, a liquid for testing a measuring apparatus;
• and
• a second region spaced apart from the first region, the second region including a storage reservoir, the storage reservoir being configured to store the liquid;
• and
• a flange disposed on the member, the flange being configured to couple the accommodating reservoir and the storage reservoir when the accommodating reservoir and the storage reservoir are folded together,
• wherein at least one of a groove, a perforation, and a crease is formed on the flange at a position between the first region and the second region,
• the storage reservoir is formed to be folded towards the accommodating reservoir in a folding direction,
• the storage reservoir includes a projection configured to perforate the accommodating reservoir when the storage reservoir is folded towards the accommodating reservoir, and
• the projection includes a flow passage for the liquid which makes communication between the accommodating reservoir and the storage reservoir when the storage reservoir is folded towards the accommodating reservoir.
