  • Patent number: 11130607
    Abstract: The present application improves the shape of a curl part of a bottle can to secure high sealability even under high pressure in the can and during heat sterilization, makes bubbling-over occur less during cap opening, and suppresses misrecognition of reseal. A bottle can has a curl part provided at an opening end of a mouth part. The curl part includes an outer wall part extending downward from an upper end bent part. The outer wall part includes a first bent part shaping a locking part that extends continuously and downwardly from the upper end bent part and shapes an outwardly-protruding convex, and a second bent part that extends continuously and downwardly from the first bent part and shapes an inwardly-protruding convex.

  • Patent number: 11059619
    Abstract: A bottle can has a curl part at an opening end of a mouth part thereof. The curl part has an upper end curved part in which an upper part of a neck shoulder part of the mouth part is curved outward and an outer wall part extending downward from the upper end curved part. A predetermined angle at which an outer edge side of a lower end face of the outer wall part opens is formed between the lower end face of the outer wall part and the neck shoulder part. An inner edge of the lower end face comes into contact with the neck shoulder part when a downward load is applied to the curl part from above.

  • Publication number: 20190329925
    Abstract: A method for manufacturing a metal bottle having a mouthpiece in an upper part of a bottomed cylindrical bottle body, including forming a screw part on the mouthpiece and then forming a curl at a tip of the mouthpiece. During formation of the screw part, a height of the first-stage screw thread from a tip side in a complete screw part and a height of the second-stage screw thread from the tip side are substantially equal and a distance between an apex part of the first-stage screw thread and a bottle axis is smaller than a distance between the apex part of the second-stage screw thread and the bottle axis. After formation of the curl, a distance between the apex part of the first-stage screw thread and the bottle axis and a distance between the apex part of the second-stage screw thread and the bottle axis are substantially equal.

  • Patent number: 10272668
    Abstract: Provided is a conveyance device capable of reducing the speed of conveyed objects, with the interval therebetween being narrowed substantially, while arranging the conveyed objects, which have been carried in one row, in a plurality of rows. The present invention includes a conveyance turret (110) that holds and conveys conveyed objects (K) and a carrying-out turret (120) that holds the conveyed objects (K) and transfers the same to a carrying-out conveyor (130), wherein the carrying-out conveyor (130) is configured to hold the conveyed objects (K) in a plurality of rows and carry out the same, the carrying-out turret (120) is provided in plurality so as to correspond to the plurality of rows of the carrying-out conveyor (130), and the conveyance turret (110) and the carrying-out turret (120) have an interval adjustment mechanism that changes radial positions of the held conveyed objects (K) according to rotation angles thereof.

  • Publication number: 20190039278
    Abstract: A blow molding apparatus improves productivity and obtains a high-quality molded product by supplying a good-quality parison to molds. A blow molding apparatus includes: a die head which discharges a parison; a parison supplying part which cuts the discharged parison at a preset length and conveys the cut parison; and a blow molding part in which the supplied parison is clamped between blow molds so as to perform blow molding. The parison supplying part has a pickup chuck which conveys the cut parison alternately to a first supplying position set on one of right and left sides with respect to a discharge center of the die head and a second supplying position set on the other of right and left sides with respect to the discharge center. The blow molding part performs blow molding at the blow molds arranged at the first supplying position and the second supplying position, respectively.
