Abstract:
A seal for sealing the mouth of a thin wide-mouthed bottle having a body formed by stretching blow molding, and a wide-mouthed bottle having a mouth sealed by the seal. A synthetic resing laminate sheet comprising an aluminum sheet or an aluminum foil as a base is punched into the same shape as the bottle mouth to form a seal. A flat peripheral portion and bellows formed by bending the sheet into alternate multiple mountain and valley portions inside the peripheral portion are sumiltaneously formed by press molding. The bellows are shaped concentrically or spirally and prevents deformation of the body resulting from cooling and pressure reduction inside the bottle.
