摘要： A dispensing container includes: an operation portion including an inner transmission shaft, the inner transmission shaft extending in the up-down direction and with inner spiral groove; a sleeve surrounding outside of inner transmission shaft and provided so as to be rotatable on container axis; middle plate body holding contents and provided inside sleeve to be movable in up-down direction in a state where rotation of middle plate body on container axis relative to sleeve is restricted; and a movable tube extending downward from middle plate body and including second engagement protrusion that engages with inner spiral groove. A sliding portion, which is formed of softer material than either one member of the sleeve and the operation portion and on which the other member of the sleeve and the operation portion slides as the sleeve and the operation portion rotate relative to each other, is fixed to the one member.

摘要： A liquid container and a liquid container with content liquid are easy to sort and dispose of, while preventing dripping of the liquid from a nozzle to the outside. A liquid container includes a container body configured to compartmentally form an accommodation space for content liquid, a tubular nozzle configured to be connected to an upper portion of the container body and guide the content liquid to the outside, and a liquid recovery channel configured to return the content liquid on the radial outside of the nozzle into the accommodation space. The container body, the nozzle, and the liquid recovery channel are formed by integral molding.

摘要： A synthetic resin container has improved formability while preventing deformation of corner walls. The synthetic resin container includes a mouth that serves as a dispensing opening for contents, a body that is continuous with the mouth via a shoulder, and a bottom that closes a lower end of the body. The body includes a pair of main walls arranged so as to face each other with a gap therebetween, a pair of side walls arranged so as to face each other with a gap therebetween, and corner walls that couple respective ends in a circumferential direction of the main walls and the side walls. Each corner wall is provided with U-shaped ribs that are formed in a substantially U-shape within a surface of the corner wall and that are concave toward an inner side in a thickness direction of the corner wall.

摘要： A method for producing a delamination container, wherein the delamination container includes an outer layer body constituting an outer shell of the container and an inner layer body that is laminated on an inner side of the outer layer body in a manner such that the inner layer body is peelable from the outer layer body. The inner layer body comprises an ethylene-vinyl alcohol copolymer resin, and is deformable to undergo volume reduction and the outer layer body includes an outer layer body's inside sub-layer that is located adjacent to the inner layer body and that is made of a polypropylene resin and an outer layer body's outside sub-layer that is located on an outer side of the container relative to the outer layer body's inside sub-layer and that is made of a polyethylene resin. The method comprises a process to form the delamination container by co-extruding resins in a molted state to prepare a cylindrical laminated parison and blow molding the prepared laminated parison.

摘要： A synthetic resin-made laminated peelable container, formed by blow molding a preform assembly in which an inner preform is assembled into an outer preform, includes: an outer layer body including a tubular-shaped outer mouth and a closed-bottom tubular-shaped trunk contiguous from the outer mouth; an inner layer body including a tubular-shaped inner mouth arranged on inner side of the outer mouth and a containing chamber laminated on inner surface of the trunk in peelable manner for volume reduction and deformation; and an ambient air inlet configured to introduce ambient air between the outer and inner layer bodies. The containing chamber is integrally provided with at least two thick ribs extending along axis line of the trunk to increase thickness of the containing chamber compared with remaining portions.
