  • Patent number: 10597200
    Abstract: A screw cap container including a container main body and a screw cap. The container main body includes a mouth tubular portion, which is provided with slope screw portions. The slope screw portions include: upper screw protrusions disposed at three or more different positions; lower long screw protrusions having left end positions same as left end positions of the upper screw protrusions, and each having a length longer than a length of each upper screw protrusion; and oblique screw protrusions extending obliquely from right ends of the lower long screw protrusions and each being connected to a left end of a different one of the upper screw protrusions. The screw cap includes a top wall and an outer circumferential wall. The outer circumferential wall is provided with cap screw protrusions disposed in the same number as the number of the upper screw protrusions.

  • Patent number: 10023347
    Abstract: Disclosed is a synthetic resin container provided with an inverting, foldback bottom wall that can maintain a stable, self-supporting position while being able to minimize the amount of residual contents, and that can be formed by blow-molding, etc., and maintain the favorable producibility or low cost of the past. The synthetic resin container is provided with a bottom wall that forms the bottom of the container, and a drum section that is united to the perimeter of the bottom wall and forms a filling space M for contents on the inside, and is a synthetic resin container wherein a raised bottom is formed by inverting and folding back said bottom wall toward said drum section. Said drum section has a lower peripheral wall that touches or approaches the outer wall part of said bottom wall and forms a self-supporting base by the inversion and folding back of said bottom wall.

  • Patent number: 8925767
    Abstract: A container with a folded-back bottom wall, which is very stable in a rest position, has a strong bottom wall, and makes it possible to minimize the amount of remaining liquid while allowing costs to be reduced is provided. The container with a folded-back bottom wall has a bottom wall and a body part and transforms into a first mode in which the bottom wall is made to project downwards from the lower surface of the body part, and into a second mode in which the bottom wall is folded back inside the body part. The boundary portion between the bottom wall and the body part is folded to have an outwardly-convex shape so that a folding groove is circumferentially formed, and the bottom wall is folded back inside the body part at the folding groove.
