Abstract
997,431. Valved bags. SICEDISON S.p.A. Oct. 26, 1961 [Oct. 29, 1960; Feb. 2, 1961], No. 38348/61. Heading B8K. A valved bag made of flexible material in sheet or tubular form 1 has a piece 4 forming the intake valve which is a rectangular strip connected by a transverse welding line 3 to the upper edge of the bag, said piece being folded in half along its length and rotated about the line 3 until its upper edge is below or in line with the upper edge 2 of the bag, said edges then being welded together. The strip 4 is rotated by 90 degrees until it penetrates into the bag and at the same time is folded along the line 5 causing the body of the bag against which the strip lies initially to be bent along the lines 6 and 6<SP>1</SP>. When the valve strip reaches the position shown in Fig. 2 the bag is closed by the welding seam 8 which at the same time forms the valve since the edges 41 and 4<SP>11</SP> of the strip are welded together. A further seam 9 provides a safety closure of the valve. As an additional closure, a cord 11 encompasses the valve body 12, its free ends 14 and 15 being led out of the bag through openings at 16<SP>1</SP>, the cord ends being pulled to clamp the valve body and then knotted and sealed together. In another embodiment the strip 4 is welded internally to the bag and in yet another the valve forming piece comprises a tubular element instead of a flat strip. Specification 909,642 is referred to.
