To retain the virginity of cylindrical articles packed in a cylindrical article package, the present invention provides a package of a novel structure and a fabrication method for the same. More specifically, the present specification discloses a package wherein a film has a slit at least either one of an upper end face and a lower end face of the package in a portion thereof corresponding to a boundary between the adjacent cylindrical articles, and more specifically, a package wherein the film has a slit along the boundary between the adjacent cylindrical articles, and is curved in such a manner as to conform to the outer circumferential surfaces of the cylindrical articles located adjacent to the boundary.

An apparatus whereby cylindrical cans formed of a ferromagnetic material and transported at high speed along a carrying conveyor in such a contiguous way as having no gaps between adjoining cylindrical cans are separated so as to provide a spacing therebetween to eliminate interference between the adjoining cylindrical cans, thereby supplying a plurality of cylindrical cans with reliability to a main index wheel of an automatic machine for producing cylindrical cans. The apparatus includes a carrying conveyor, star index wheel, supply index wheel and main index wheel. The supply index wheel has permanent magnets, each holding an individual cylindrical can by suction. The transport speed of a plurality of cylindrical cans transported along a conveyor at high speed is reduced for a moment by the star index wheel. Then, each respective cylindrical can is held by suction caused by magnetic force from permanent magnets disposed around the outer edge of the disc-shaped supply index wheel and spaced uniformly to provide a spacing between adjoining cylindrical cans. While maintaining the foregoing spacing, the cylindrical cans are supplied to the main index wheel of the automatic machine for producing cylindrical cans.

Apparatus for separating and supplying cylindrical cans and method therefore

A battery includes a pair of an anode electric power generating source element and a cathode electric power generating source element for generating an electric power, and a container receiving therein the electric power generating source elements. The container includes a breakable portion which is breakable such that a gas from at least a part of the electric power generating source elements is allowed to flow out of the container therethrough when a pressure in the container increases excessively. The battery further includes a variable throttle for the gas which is elastically deformable by the pressure in the container such that the gas is allowed to flow out of the container.
