  • Publication number: 20230042216
    Abstract: By providing a depressed portion 7 in a container main body 1a, forming a thick portion 5a in a covering layer 5 on an edge portion 7b of the depressed portion 7, and forming a thin portion 5b adjacent to the thick portion 5a in the covering layer 5 on a bottom surface 7a side of the depressed portion 7, when a synthetic resin container including a container main body molded into a predetermined container shape and a covering layer laminated on an outer peripheral surface side of the container main body is discarded, the container main body and the covering layer can be easily separated.

  • Publication number: 20220355974
    Abstract: Provided is a synthetic resin container that includes a container main body molded into a predetermined container shape and a covering layer laminated on an outer peripheral surface side of the container main body. A label is mounted on a container body portion. The container main body is provided with a step portion formed by raising or denting a peripheral surface that extends continuously or discontinuously along a predetermined direction and the covering layer is provided with, continuously or discontinuously along the step portion, a linear thin portion that is linearly thinner than a surrounding area. At least part of the label is adhered to a portion of the covering layer adjacent to the linear thin portion.

  • Patent number: 10774248
    Abstract: An oxygen-absorbing film having an oxygen-absorbing adhesive agent layer comprising an oxygen-absorbing adhesive agent resin composition, wherein the oxygen-absorbing adhesive agent layer has at least two glass transition temperatures, and wherein the lowest glass transition temperature among the glass transition temperatures is lower than 0° C. The oxygen-absorbing adhesive agent resin composition preferably comprises: (A) an oxygen-absorbing polyester resin having a glass transition temperature of ?20 to 10° C. made from a tetrahydrophthalic acid, a derivative thereof, a tetrahydrophthalic anhydride, or a derivative thereof, and (B) a saturated polyester resin having a glass transition temperature of ?10° C. or lower that is a polyester resin containing substantially no carbon-carbon double bond group, and can be obtained by, for example, polycondensation of a dicarboxylic acid component, a diol component, and a hydroxycarboxylic acid component.
