Therefore, it is necessary for the resin container to have heat resistance that can withstand the heat of hot filling, and in order to impart the heat resistance to the resin container, heat setting (heat setting) after blow molding is generally performed. ing.
  • a container having a reduced pressure absorption part is known as a conventional resin container. The reduced pressure absorption part is curved and displaced in response to the internal pressure fluctuation due to hot filling and the volume fluctuation of the content liquid, thereby preventing the deformation of the resin container (for example, see Patent Document 1).
  • An object of the present invention is to prevent deformation of a light-weight resin container and improve heat resistance.
  • the first characteristic configuration of the resin container of the present invention is that, in a resin container provided with a reduced pressure absorbing portion, two grooves intersecting each other are provided on the bottom wall of the reduced pressure absorbing portion.
  • the second characteristic configuration is that the two grooves intersect along a diagonal line of the bottom wall of the decompression absorbing portion.
  • the bottom wall of the vacuum absorber is divided by the two grooves intersecting along the diagonal line of the bottom wall of the vacuum absorber.
