20090046958Opening mechanism for a flexible container - An opening mechanism for use with a fluid filled collapsible container is disclosed. The mechanism comprises an outlet spout adapted to be joined to a wall of the collapsible container, a perforator for opening the collapsible container through the outlet spout and a driver having a passage therethrough. The driver is received within the outlet spout and screw threadedly engaged therewith for advancement by relative rotation thereof to drive the perforator though the outlet spout to thereby open the collapsible container and permit fluid to be dispensed through the passage. A circumferential flexible seal is provided within the outlet spout on one of the driver and the outlet spout to engage with the other of the driver and the outlet spout to reduce leakage of fluid between the outlet spout and the driver as the collapsible container is opened.02-19-2009
20100215294DISPOSABLE BEVERAGE POUCH WITH NIPPLE - A disposable beverage container is disclosed having an aseptic flexible pouch filled with a beverage, and a nipple apparatus attached to an upper surface.

20120275730ZIPPER TAPE AND PACKAGING BAG WITH ZIPPER TAPE - Since a rib having a thickness substantially equal to a thickness of each of first and second thick portions is provided in a cutting portion of a zipper tape, the first and second thick portions and the rib can be bonded to an inner surface when the zipper tape is bonded to a bag body. Accordingly, when tearing a packaging bag for opening, stress concentrates on a thin portion having a small tensile strength, so that the packaging bag can be cut at a single cutting position in the thin portion. Consequently, no cutting fragment is generated. Moreover, since a cutting line is positioned by the rib when tearing the packaging bag, the cutting line is not waved, so that the packaging bag can easily be torn with a linear cutting performance.11-01-2012

20100119180PAPER VALVE SACK WITH INNER CATCH - A description is given of a paper valve bag with an inner panel which is located at the paper-bag end which is located opposite the paper-bag end with valve, and, on its surface which is directed toward the sack interior, the inner panel has an opening aid which has a higher modulus of elasticity than the inner panel. The opening aid, which may be a tear-open strip or a tear-open thread, projects beyond the inner panel at at least one surface-area end of the latter. Such paper valve bags are used for fine-grain, pulverulent and/or free-flowing materials, in particular ready-to-use mortar.05-13-2010
20110293207EASY OPEN BAG - An easy open bag and method for making the same.

20130209003BAG PACKAGING - A pouch-type packaging for packaging pourable contents and having a front wall and rear wall made from at least one flexible packaging film is such that the front wall and the rear wall are joined together via a sealing seam. The sealing seam is extended in a region bordering a sealing zone oriented away from the sealing edge with a free end furthest removed from the sealing edge. The front wall of the pouch exhibits an outer layer on the side directed towards the outside of the pouch. The outer layer and the part of the front wall of the pouch lying under the outer layer delimit a outlet zone for the contents in an area which encloses the free end of the sealing zone and extends to an edge of the sealing edge. The application of pressure produces a tear in the part of the front wall of the pouch lying under the outer layer in the region of the free end of the sealing zone and the contents enter the outlet zone and emerge from the pouch at the edge of the sealing edge.08-15-2013
