Definitions

  • the invention relates to a peel seam opening aid and method for opening peel seams of a multichamber bag.
  • multichamber bags for example multichamber nutrition bags
  • the multichamber bag has two or three individual chambers.
  • the multichamber bag has four, five or even more than five individual chambers.
  • the peel seams separating the individual chambers have a lower sealing strength than contour seams of the multichamber bags.
  • the multichamber bags have a first end with a port system and an opposite second end with an edge referred to as bottom edge. The expression bottom edge is only used to distinguish the edge from other edges. In use, the bottom edge typically is arranged at a top.
  • One known procedure to open the peel seams is to roll-up the multichamber bag starting from the bottom edge opposite to the port-system of the bag. By rolling up the bottom edge of the bag, an internal pressure is built-up inside a chamber closest to the bottom edge up to a level that causes a peel seam separating this chamber from another chamber to open.
  • US 2017/101253 A1 shows a peel seam opening aid with an elongated central part having two distal gripping elements.
  • the central part has a means for fixation of a partial area of a multichamber bag, which in the most preferred embodiment of US 2017/101253 A1 comprises a moveable clamping element.
