摘要： An improved multiwall, gusseted, stepped end pinch style bag is disclosed with provisions for forming a valve in one end thereof. The bag is prepared from a plurality of plies of flexible material such as kraft paper or the like and comprises at least one inner ply and one outer ply each of which is cut and scored to permit a valve area to be formed at one end when the gussets in that region are infolded while still retaining the conventional pinch style closure.

摘要： A block bottom valve bag comprises an elongated bag tube having opposite ends. One end of the bag is folded to form a block bottom closure comprising first and second side flaps folded toward one another in overlapping relationship and adhered to one another, and a pair of end flaps extending inwardly beneath the side flaps at the opposite ends thereof. An elongated valve member extends between one of the end flaps and overlapped side flaps. The valve member comprises an elongated flexible valve tube collapsed into a flat configuration having upper and lower walls in facing relation. The upper wall is operatively secured to the interior surfaces of the side flaps and the lower wall of the valve tube is operatively secured adjacent one end thereof to the end flap and is detachably secured adjacent the other end thereof to the end flap. A reinforcing sheet member may be interposed between and adhered to the under surface of the side flaps and the upper surface of the valve tube.

摘要： One corner of a plastic bag is provided with an inwardly extending triangular fold. A rectangular insert of plastic having a reverse fold along one edge thereof is folded along a center line transverse to the reversely folded edge and secured in the triangular fold at the corner of the bag with the side edges of the insert which are perpendicular to the reverse fold being flush with the top edges of the bag. The top edges of the bag and the side edges of the rectangular insert are secured together so that the insert defines a sleeve adapted to fit over the end of a cylindrical filling spout. When the bag is completely filled the sleeve and top edges of the bag will be flattened out in a substantially horizontal plane and the reversely folded flap on the insert can be pulled out and re-folded over the top of the bag to close off the sleeve to substantially prevent the loss of the contents of the bag while permitting the escape of air from the interior of the bag.

摘要： A bag device comprising side walls and opposite ends with at least one end including a closure means closing a charging and discharge opening. The closure means includes a pair of end flaps which are folded inwardly towards the opening. A pair of side flaps extend inwardly over the end flaps and the opening. A passageway extends between one of the end flaps and the side flaps which is in communication with the opening to permit insertion therein of a charging spout. A flexible sleeve is secured to the said one end flap so that when the side flaps and sleeve are longitudinally ruptured to permit the emptying of the bag, the ruptured sleeve and end flap can be folded outwardly from the opening to form a pouring spout adjacent the opening.

摘要： A bag of tubular form closed at one end and partially closed at the other end by a first rear wall portion being folded over and sealed to a front wall. The opening between a second rear wall portion and opposed front wall forms the valve which is sealed after filling by folding the longitudinally extending second rear wall portion over and sealing it to the opposed front wall using the folded first rear wall portion as a reference. Adjacent lateral termination of the plural ply rear wall portions are oppositely stepped so as to overlap when sealed to the front wall.

摘要： A packaging container having a pressure equalizing or venting valve which includes a valve seat, a pair of opposed faces and a valve opening therebetween. One of the faces is adapted to be secured to a wall of the packaging container surrounding an aperture which is located therein. A flexible valve diaphragm at least partially surrounds and substantially covers the valve opening on the other side of the faces and of the valve seat. A separation layer is secured to at least a portion of one of the faces of the valve seat and at least partially surrounds the valve opening. The separation layer is positioned between the other face and the flexible valve diaphragm to establish a pressure equalizing or venting passage extending from the valve opening through the flexible valve diaphragm.

摘要： In a composite bag comprising an outer bag and an inner bag which is secured thereto by adhesive, the outer bag is provided with a cross-bottom folded closure at least at one end where no filling valve is provided. Adjacent said one end of the outer bag, the inner bag is closed by a weld seam and folded back on itself and secured in position so that, in a flattened condition of the composite bag when the cross-bottom folded closure lies snug against the bag body, the inner bag extends no further than the centre line of the cross-bottom closure.

摘要： This disclosure relates to a vent valve arrangement for a sealed package wherein when excessive pressures occur within the sealed package, gases will automatically be vented therefrom. The vent valve includes at least one perforation in the package with the perforation being formed through one of two walls of the package into the interior thereof and there being a resistance path from the interior of the package to the perforation with the resistance path being openable by forces expanding the walls whereby pressure that is caused by the formation of gases and vapors within the package will open the resistance path and escape through the perforation.
