Abstract: Provided is an article sorting device that can handle various containers without necessarily requiring a change of parts. The article sorting device includes a rotating table, a pocket, a guide, a position control unit, and a sorting unit. The position control unit controls a radial position of the pocket to a specified position that is a first position or a second position located radially outward relative to the first position. The sorting unit guides an article to different paths depending on whether the radial position of the pocket is at the first position or the second position when a circumferential position of the pocket reaches a sorting position.

Abstract: Provided is a transport device that can transport two or more types of articles without necessarily requiring a change of parts. The transport device includes a guide extending in a transport direction of an article, and a holding unit configured to hold the article between the holding unit and the guide and to move in the transport direction. The holding unit includes two or more roller units. In each roller unit, two or more rollers, including a first roller and a second roller with a diameter larger than a diameter of the first roller, are aligned along an axial direction. The holding unit is movable in the axial direction. The holding unit is moved in the axial direction to thereby switch the rollers abutting the article among the two or more rollers.

Abstract: A bottle container includes: a tubular inner container 2 including a cap at an upper portion thereof; and an outer container 3 mounted so as to extend along a trunk 5 and a bottom 6 of the inner container 2, the inner container 2 includes a shoulder 8 at the upper portion which is not covered with the outer container 3, an outer peripheral portion 13b of a bottom 13 of the outer container 3 is made thicker than a side wall 14 of the outer container 3, a center portion 13a of the bottom 13 of the outer container 3 is made thinner than the outer peripheral portion 13b to form a space 13c, and the outer container 3 mounted to the inner container 2 and the shoulder 8 of the inner container 2 are covered with a heat-shrinkable film 4.
