PROBLEM TO BE SOLVED: To provide a cap or the like enabling repeated isolatingly taking-out operations using a variety of analyzers, while also preventing evaporation, deterioration, etc., of a liquid reagent housed, and eliminating the need for removing it from an opening during isolation. SOLUTION: The cap 4 comprises a main cap body 4a covering an opening 3 in a main container body 2 and capable of being repeatedly stabbed with the reagent probe of an analyzer and closing a hole by means of its elasticity after the probe is removed; and a cylindrical skirt member 4b joined to the main cap body 4a while in intimate contact with the inner or outer peripheral surface of the opening 3 to prevent the main cap body 4a from coming off the opening 3, with the main cap body and the skirt member integrally made of an elastomer. After the cap 4 is inserted in the main container body 2, a liquid reagent can be isolatedly taken out whenever necessary without having to remove the cap 4. COPYRIGHT: (C)2004,JPO
