Abstract: 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.

Abstract: 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.
Abstract translation: 塑料袋的一个角落设有向内延伸的三角形折叠。 沿着其一个边缘具有反向折叠的塑料矩形插入物沿着横向于反向折叠的边缘的中心线折叠，并且固定在袋的拐角处的三角形折叠部中，插入物的侧边缘垂直于相反的边缘 折叠与袋的顶部边缘齐平。 袋的顶部边缘和矩形插入件的侧边缘固定在一起，使得插入件限定适于装配在圆柱形填充口的端部上的套筒。 当袋子完全充满时，袋子的顶部边缘将在基本上水平的平面中被平坦化，并且插入物上的反向折叠的折片可以被拉出并重新折叠在袋的顶部上以封闭套筒 以基本上防止袋的内容物的损失，同时允许空气从袋的内部逸出。

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
