ABSTRACT:
A synthetic resin bottle-type container includes a shoulder portion continuous with a mouth portion through which contents can be poured out, and a body portion forms a space for accommodating the contents over an area extending to its bottom wall from the shoulder portion. The body portion includes pressure-reduction absorbing panels defined by at least one groove that projects inwards of the container. For preventing the shoulder portion from deformation due to the absorption of the pressure-reduction, the groove for the pressure-reduction absorbing panel immediately below the shoulder portion is provided with a recess extending along the groove and having a depth larger than that of the groove.
