Abstract: An overwrap packed body is obtained by heating and shrinking a wrapping material in a condition that five drink products collectively wrapped by the wrapping material. Three perforated lines passing through gap portions between the adjacent drink products are formed on the wrapping material at an interval of 2 mm in parallel. When the three perforated line portions are pushed with fingers in the gap portion between the adjacent drink products, the wrapping material torn from the pushed portion in a vertical direction. Thus, the packed drink products DG can be easily taken out one by one.

Abstract: [PROBLEM] To provide a novel inspection method and system of a container enabling inspection of excess entrainment of air inside a flexible container and inspection of seal defects of a flexible container to be performed by a single technique simultaneously, enabling a full run of flexible containers to be continuously inspected on the production line, and giving a high inspection precision. [MEANS FOR SOLUTION] Inspecting for seal defects of a container and excess entrainment of air in a container in an inspected object comprised of a flexible container in which a liquid is filled, during which placing the inspected object in an air-tight container, sucking out the air in the air-tight container to reduce the pressure sufficient to make container outer walls of the inspected object expand, measuring an expansion dimension of the container outer walls, and comparing it with a preset threshold value to judge the quality of the inspected object.
