Non-cover self-sealing device for soft packaging
Patent Name Soft-packed self-sealing device without cover for patents Patent Applicant Xia Chunfeng Principal Applicant Address 471003 No.202, No.1, Building 7, Nanfeng, Lichun West Road, Longxi District, Luoyang City, Henan Province Inventor Xia Chunfeng Application (Patent) No. 200420074526.6 Date of Application 2004.08.24 Certification date Approval Notice No. 2744612 Auditing announcement date 2005.12.07 Manual CD-ROM number D0549 Main classification number B65D35/50 Classification No. B65D35/50 Subsidiary Original application number Priority document Abstract This invention relates to the field of packaging technology. The proposed self-sealing device for capsulation of soft packaging is provided with a self-sealing device at the extrusion port of the soft packaging container. The self-sealing device is composed of a reed, a sealing piece and a reed abutment; the reed has a curved shape. The upper end is connected with the sealing sheet, and the lower end is connected with the reed abutment, and is fixed on the two sides of the extrusion mouth of the soft packaging container through the reed abutment. The utility model is novel in design and reasonable in structure, and breaks through the cap body structure of the conventional soft packaging container. Since the self-sealing device is arranged at the extrusion outlet end of the soft packaging container, the elastic deformation of the self-sealing device material, ie, deformation memory, is utilized. Function to realize the automatic opening and closing function of the software packaging container in use, thus eliminating the need to repeat the process of opening and closing the lid, without greatly affecting the performance of the existing software packaging container. Users. Sovereignty Item 1.
