ABSTRACT:
The invention relates to a multiple pot comprising individual pots interconnected by connector portions so as to be capable of being pulled out. The multiple pot is used to raise and transplant seedlings of plants. The invention also relates to a method of fabricating the pot. The pot is designed especially to promote growth of roots across the side walls of the individual pots after transplantation. Also, the resistance encountered when the multiple pot is unfolded is reduced. Further, the individual pots are uniform in size. These feature arise from the facts that the connector portions are formed by applying a waterproof paste discontinuously and that a water-soluble paste is not applied around the edges of the individual pots created when the multiple pot is unfolded. Hence, a coating of the paste is formed in none of these portions. The multiple pot is fabricated by continuously carrying out three steps. At the first step, the waterproof paste is applied in a given pattern while continuously pulling out two continuous thin films. At the second step, folds are formed in the resulting belt, and the belt is folded in a zigzag fashion. This state is maintained. At the third step, the water-soluble paste is applied to the front side and the rear side of the belt alternately up to each fold. Then, the belt is folded, and pressure is applied to it to stick together the folded belts.
