COLLECTED BOTTOMED FLOWERPOT FOR TRANSPLANTING REARED SEEDLING AND PRODUCTION THEREOF

摘要

PURPOSE:To readily obtain collected bottomed flowerpots having a few soil falling phenomena by arranging a great number of bottomed flowerpots with partial bottom made of extension parts of a pair of opposing side walls of flowerpots and bonding adjoining flowerpots with a water-soluble adhesive. CONSTITUTION:A water-resistant adhesive 3a is partially stuck in thin width to the side edge of a thin film 1 made of paper, etc., to form a hollow material having open top and bottom. Then a water-resistant adhesive 3b is stuck in thin width of given length to a middle position section of open edge of the top or the bottom of the hollow material, the bonding edges of the water-resistant adhesives at the side edge and the open edge are regarded as limiting positions, the uncoated section of the water- resistant adhesives is cut out in a dent state to form a T-shaped flat material 8. Then the flat materials 8 are vertically and alternately superimposed by each 1/3 to 1/4 widths of the wing parts 9 of the flat materials and the superimposed parts are bonded with a water-soluble adhesive 7. Then a great number of the prepared unit materials 14 are laminated in multiple stages and the water-soluble side walls of flowerpots to give a collected material Pa of bottomed flowerpots P1 having partial bottom 4 made of extension parts 6-1 and 6-2 of a pair of opposing side walls of flowerpots.
