Biological sample storage tube cap, and biological sample storage container equipped with same

A biological sample storage tube cap comprising:

• a main body portion that has a lower face and an upper face arranged parallel in a vertical direction and oriented oppositely;
• an elongated biological sample adhering portion that extends downward in the vertical direction from the lower face of the main body portion;
• a biological sample associated information presenting plate-shaped portion that extends upward in the vertical direction from the upper face of the main body portion by a predetermined length;
• and
• a flange that protrudes outward from the main body portion in a radial direction, which is perpendicular to the vertical direction,
• wherein the biological sample storage tube cap is to be attached to a hollow biological sample storage tube having a lower closed portion and an upper opening portion, and that is for closing the upper opening portion,
• the main body portion is configured to enter the upper opening portion of the biological sample storage tube and close the upper opening portion,
• the biological sample adhering portion is enterable in the biological sample storage tube and cuttable and a cut piece formed by cutting of the biological sample adhering portion can fall into the biological sample storage tube,
• the biological sample adhering portion includes a leading end portion whose outer shape becomes smaller toward the leading end,
• the main body portion and the biological sample adhering portion are made of different synthetic resin materials, and a base end portion of the biological sample adhering portion enters the main body portion where the base end portion is fixed,
• the biological sample adhering portion has a plate shape such that two flat faces are provided on two sides of the plate shape wherein normal vectors of the flat faces are defined as being oriented in a thickness direction of the biological sample adhering portion, the thickness direction is perpendicular to the vertical direction, and a thickness of the biological sample adhering portion measured in the thickness direction is 0.05 to 0.5 mm,
• the biological sample associated information presenting plate-shaped portion has flat surface portions of which surfaces are flat and of which normal vectors are oriented in the same direction as the thickness direction of the biological sample adhering portion,
• a width of the biological sample adhering portion, which is measured in the width direction, is larger than the thickness of the biological sample adhering portion, and
• the width of the biological sample adhering portion is 0.3 to 2 mm.
