摘要： PURPOSE:To detect a pinhole by slanting a container which contains a conduc tive material and has its opening part hermetically sealed with a lid and bring ing the content into contact with the sealed part, dipping the container in the conductive permeating liquid in an insulating container, and applying a high frequency to the container and permeating liquid. CONSTITUTION:The conductive contents 5 are stored in the plastic container 2, which is covered with a top film 4 to form the hermetically sealed part 6. An earth electrode 20 is fitted in the container 2, which is slanted to bring the conductive contents 5 into contact with the sealed part 6. While the sealed part 6 of the container 2 is brought into contact with the conductive permeating liquid 32 injected into the insulating container 31, a container rotating means 22 is rotated by a motor 21 to bring the entire sealed part 6 into contact with the permeating liquid 32 in order. Simultaneously, a power source 11 applies a voltage to the earth electrode 20 and a buried electrode 30 through a resis tance 12 and an ammeter 13 and variations of the indications of a voltmeter 14 and the ammeter 13 between both the electrodes are detected. Consequently, the pinhole of the hermetically sealed part 6 is easily detected. The method is suitable for the inspection of a food container as to fruit juice.

摘要： PURPOSE:To obtain a packaged form with an improved opening property, by forming a sealing part, which seals a content, on the packaging material and forming a linear fused part for opening, which reaches the edge of the packaging material, at said sealed part. CONSTITUTION:For a packaged form 30, in order to seal a content, such as food, etc., both side ends of a band shaped packaging material 9 are stuck together on the back side in an envelop state or flap to flap state to give a tubular shape. At the same time, at a slightly inner position from upper and lower edges 9A of this tubular shaped packaging material 9, a sealed part 31 has been formed in a linear shape respectively at a right angle to the axial direction. At the sealed part 31, a fuse linear shaped fused part for opening 32, which reaches the edge 9A of the packaging material 9, is formed, and the packaged form 30 is opened by tearing the packaging material 9 from this fused part for opening 32. Therefore, the opening property of the packaged form is improved.

摘要： PURPOSE:To easily detect a pinhole by slanting the container which contains a conductive material and has its opening part hermetically sealed with a lid, rotating the container while bringing its contents into contact with the sealed part, and applying a high frequency between the earth electrode of the container and the slide electrode of the sealed part. CONSTITUTION:The conductive contents 5 are charged in the plastic container 2, which is covered with a top film j4 to form the sealed part 6. While the container 2 is slanted to bring the contents 5 into contact with the sealed part 6, a container rotating means 22 is rotated by a motor 21 to bring the entire sealed part 6 into contact with the slide electrode 31 in order. High frequency electric power 11 generated by a high frequency voltage generating device 10 is applied between an earth electrode 20 fitted to the bottom part of the container 2 and the slide electrode 31 is applied through a resistance 12 for protection and an ammeter 13. The ammeter 13 is read to detect whether or not there is a pinhole. Consequently, the pinhole is easily and securely detected. The method is suitable for the inspection of a food container as to fruit juice, etc.

摘要： PURPOSE:To securely obtain a close seal without defects at the edges of sealed part and pinholes, by rubbing double stacked film cylinders of a required length in the axial direction filled with contents to remove the contents and then by applying a ultrasonic sealing to the film cylinder. CONSTITUTION:A cylindrical film 7B, having been made flat to fill contents and to be an edge at a rubbing face 7C, is transferred between rubbing arms 41, 42 and a ultrasonic horn 50 to press the cylindrical film 7B between the mutually contacted tips of the arms 41, 42 and the ultrasonic horn 50 to leave only the nearly cylindrical film 7B between the rubbing arms 41, 42 and the ultrasonic horn 50 by removing the contents within the cylindrical film 7B both upward and downward. An anvil 51 is transferred thereafter to contact it to the cylindrical film 7B for generation of ultrasonic waves and to heat-seal the cylindrical film 7B by the particle heat generated due to the mechanical vibration. The heat-sealed part with the ultrasonic waves is cut off by a cutter 6 to produce a pack as a product.
