Title:
MANUFACTURING DEVICE OF TETRA-SHAPED PACKAGING BODY
Document Type and Number:
Japanese Patent JP3432834
Kind Code:
B2
Abstract:
PURPOSE: To prevent wrinkles from generating at the time of lateral sealings to improve the appearance, and at the same time, prevent the content from leaking out.
CONSTITUTION: After injecting a gas from injection nozzles 42, 44 which are located in parallel with holding plates 51, 52, a packaging material 9 is pressed by the holding plates 51, 52, and a first lateral seal line is formed. Then, the holding plates 51, 52 and a lateral sealing machine are integrally rotated by 90°, and after injecting a gas from injection nozzles 41, 43 which are located in parallel with the holding plates 51, 52, a second seal line is formed. Thus, by performing the first and second lateral sealings, which are mutually rectangular, by rotating the lateral sealing means at each 90°, a tetra shaped packaging body is manufactured. Since the gas is injected in the packaging material 9 in the same direction with these lateral seals, the packaging material 9 is extended into a flat shape in the sealing direction, and the packaging material 9 is prevented from generating wrinkles. For this reason, the lateral sealings can be perfectly performed.
