Patent Name Packed Packaging Device, Method, Package, and Manufacturing Method Patent Applicant Kureha Chemical Industry Co., Ltd. Principal Applicant Address Chubu-ku, Chuo-ku, Tokyo Prefecture Japan, Shiodome-cho, No.9, No. 11, No. 11 Inventor, Hirokawa Koji Application (patent) No. 02814784.7 Date of application 2002.12.25 Approval date Approval notice No. 1535228 Approval announcement date 2004.10.06 Manual CD-ROM D0440 Main classification number B65B9/12 Classification number B65B9/12; B65B51/08 Sub-division Original application No. Priority abstract Application A device, a method, and a package for producing a package that has sufficient and uniform sealing strength and that does not generate pores even when heat-treated. A strip-shaped film (F1) drawn from the web (1) is formed into a tubular film (F1), and a content of the film is filled in the tubular film (F1) after the vertical sealing and formed on the tubular film at a predetermined interval. In a filling and packaging device having no content portion (10A) and forming a transverse seal in the content-free portion (10A), the transverse sealing device (12) includes a primary sealing member, a bundling member, and a secondary sealing member. Within the range of the contentless area (10A) of the tubular film (F1), a linear transverse seal (S1) is performed at two spaced locations along the direction of travel, or a banded cross is formed between the two locations. The seal (S1), the bundling member, and the secondary sealing member (16) gather the film in the widthwise direction of the transverse seal between the above two positions, and in the assembly portion, the film at two other positions in the advancing direction. Seal. Claims 1. A filling and packaging apparatus comprising: a formed template of a tubular film having a strip-like film formed with a coincident portion at a side edge thereof, and a longitudinal direction of the traveling direction formed along the overlapping portion on the downstream side of the formed template. A vertical sealing device for sealing, a nozzle device that enters into the forming template and fills the content in the tubular film after the longitudinal sealing, and a twist forming device for forming a content-free region on the tubular film at predetermined intervals in the traveling direction. A transverse seal device for forming a transverse seal is formed at the content-free region, and the transverse seal device includes a primary seal member and a bundle member and a secondary seal member, wherein the primary seal member is within the range of the non-content portion of the tubular film. A linear transverse seal is performed at two spaced locations along the traveling direction, or a band-shaped transverse seal is performed between the two positions, and the bundling member and the secondary seal member are disposed on the downstream side of the primary seal member. And after the primary sealing member is horizontally sealed, the film is bundled in the width direction of the transverse seal between the two positions, and The film is sealed at two other locations in the bundled section in the aforementioned traveling direction.
