<P>PROBLEM TO BE SOLVED: To provide a plug body which releases the closing of an opening by specified pressing and forms an opening/closing plug mechanism for closing the opening by the releasing of the pressing, and can efficiently perform both of the manufacturing of the plug body itself and the manufacturing of the opening/closing plug mechanism using the plug body, and to provide the opening/closing mechanism using the plug body. <P>SOLUTION: For the plug body P, a cylinder-like supporting section PA, a plug PB which closes the tip of the supporting section PA and forms a disk bottom section shape, and an annular packing section PC which protrudes outside in the diametrical direction at a base of the supporting section PA are provided, and the plug body P is integrally formed of an elastomer material having rubber-like elasticity. A cap Q is fastened by making a female screw QS of a larger-diameter cylindrical section QD engaged with a male screw B2 which is provided on the outer peripheral side of the mouth B1 of a bottle B with the plug body P housed by adjusting the axial directions and tip sides of both the parts. <P>COPYRIGHT: (C)2007,JPO&INPIT |
