  • Patent number: 9932136
    Abstract: The present invention relates to a pouch and a method for making the same. In the inventive method, which is adapted to produce pouches having a limited amount of fusible material, a heat-sealable cord is arranged on a web forming confronting side surface of each pouch. Those confronting side surfaces are fused by heating the heat-sealable cord. The present invention furthermore provides a pouch, in particular containing a brewable or extractable commodity such as tea, with a pocket defined between confronting side surfaces of a web. The pouch of the present invention can have a limited amount of fusible material as the confronting side surfaces are joined by solidified melt of a heat-sealable cord arranged in vicinity of at least one edge of the pouch.

  • Patent number: 9902516
    Abstract: The present invention relates to a method for making pouches providing a continuous web; folding the web to provide confronting side surfaces joined along a bottom edge; forming a vertical seal between the confronting side surfaces, thereby providing a series of adjacent pockets having opposite side walls with each pocket having an unsealed opening along a top edge; filling the pockets through the unsealed opening with material; sealing the unsealed opening. In the inventive method, which facilitates handling of the continuous web forming the pouches, the web is perforated by a perforation between a leading length piece of the web adapted to form a leading pocket and a trailing length piece of the web adapted to form a trailing pocket, and the distance between a trailing edge of the leading length piece and a leading edge of a trailing length piece is increased for tearing the leading and the trailing lengths pieces apart at the perforation.
