Abstract: A joined assembly includes: a first member; a second member which has a facing part facing the first member in a thickness direction thereof; and joints lying along the facing part to join the first member and the second member to each other. The joints include: a pair of end joints respectively located at the opposite end portions of the facing part; and an intermediate joint located between the end joints and having a lower joining strength than the end joints. The end joint includes a fastening member mechanically joining the first member and the second member. The intermediate joint includes a friction-stirred part joining the first member and the second member by friction stir.

Abstract: A laminated tube container has the body comprising a sheet material comprising a substrate, a silicon oxide deposited layer, a heat buffer layer and an extruded coating layer of a thermoadhesive resin which are successively formed in a laminate. The heat buffer layer prevents cracks from being produced in the silicon oxide deposited layer by the heat coming when the extruded coating layer of a thermoadhesive resin is laminated. The heat buffer layer is preferably formed by dry lamination or non-solvent lamination which requires no heating. An anchor coat layer may optionally be provided between the heat buffer layer and the extruded coating layer of a thermoadhesive resin so that the adhesion strength between these layers can be improved.

Abstract: A divisible package box comprising a main sheet and a partition body, the main sheet including a bottom, two side and two cover sections, flaps and a cutting line such as a cutting tape or a perforated line across the bottom section and the bottom flaps, the partition body consisting of two partition members in back to back contact with each other, each partition member including a partition section and two end sections at its ends, the sections and the flaps being defined by score lines for folding therearound. The end sections and the side flaps constitute end faces of an assembled package box so that the inner surfaces of all faces thereof may be completely flat. The assembled package box may be divided into two small boxes along the cutting line and the partition sections which constitute each end face of the divided two small boxes.
