PROBLEM TO BE SOLVED: To provide a cap that can prevent deformation, as much as possible, caused by internal and external heating and preventing deformation even when steam is used for attaching a shrink film and having no trouble such as infiltration of shower water to the inside during cleaning by hot water shower and cooling.SOLUTION: A cap formed with a synthetic resin as a whole includes a cap body A1 standing up a spouting tube 13 at a top plate center part extended from an upper end of an installing tube 10 fitted to an outer periphery of a container opening neck part and standing up an annular locking protrusion part 16 on an outer periphery of the spouting tube, and a cover A2 arranged on the cap body at an opened and closed state via a hinge 50 and making a locking part 23 for fitting and sealing an outer peripheral surface of the locking protrusion part 16 arrange on an inner peripheral lower end of a peripheral wall in a dented annular shape. A fitting protrusion part 18 is projectedly arranged on either of an upper surface peripheral edge of the cap body and a lower surface peripheral edge of the peripheral wall of the cover, and a fitting recessed part 26 fitted with the fitting protrusion part is formed in a dented shape on the other one of them. |
