Patent number: 9932136Abstract: 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.Type: GrantFiled: September 28, 2012Date of Patent: April 3, 2018Assignees: Teepack Spezialmaschinen GmbH & Co.

Patent number: 9902516Abstract: 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.Type: GrantFiled: January 29, 2015Date of Patent: February 27, 2018Assignees: Teepack Spezialmaschinen GmBH & Co.

Patent number: 7401450Abstract: This invention concerns an infusion bag, especially for tea, which has a top part with folded down corners and a middle part folded over it, to which a string with two free ends is attached that goes from one side of the top part through a hole in the folded down parts forming a loop on the other side of the top part and comes back, whereby the two free ends are drawn up through the loop laid over the top edge of the infusion bag and pulled to form a knot. The solution in the invention is characterized by the fact that two holes are made in the top part at a lateral distance next to one another, on the left and right of the longitudinal axis of the bag; each hole goes through a folded down corner and the middle of the top part; by the fact that the string forms a loop and one end goes through one hole and the other end through the second hole; by the fact that the loop is laid over the top edge of the infusion bag, and both ends of the string go up through the loop to form a double knot.Type: GrantFiled: May 9, 2003Date of Patent: July 22, 2008Assignee: Teepack Spezialmaschinen GmbH & Co.KGInventors: Wilhelm Lohrey, Stefan Lambertz, Manfred Hauers, Dieter Vits
