<p><P>PROBLEM TO BE SOLVED: To provide a square-shaped resin-made container having heat resistance, high vacuum absorptivity, and a side wall with high strength, and easy to be handled. <P>SOLUTION: The square-shaped resin-made container has a square crosssection, has heat resistance capable of pouring a content liquid under a high-temperature condition, forms a barrel without forming a recess for depressing the periphery of the barrel to the inside of the container at the middle of the barrel, provides vacuum absorbing panels on respective side walls forming four side faces of the barrel, and forms a reinforcing recess with an approximately triangle shape on the top of the barrel. No deformation is generated thereby by making a vacuum in the container, and as the section of the barrel is rectangle, carrying and handling are easy. When the container is held, it is possible to hook fingers on the triangle reinforcing recess from both sides of the container, and to facilitate to take up the container and to handle the container when the content liquid is poured. As an outer peripheral wall bent from the side wall is formed along the outer periphery of the reinforcing recess, the strength of the top of the barrel is improved. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
