<p>A water-closet disposable pouch (8) has a pull-away tab (20) secured to one wall (10) by a weld or bond (22). Pulling away the tab (20) tears open the pouch wall (10) along the weld or bond by tearing out material (30) from the weld, thus creating one or more gaps (28). The tab (20) may be V-shaped, and define a flap or hatch area (26) of the wall behind the tab (20) which is released when the tab (20) is torn away. Any gas trapped in the pouch can escape through the opening when the pouch is placed in a WC. In an alternative form, a tear-out filament is secured to or within a wall of the pouch parallel to a direction of orientation of the plastics material. <IMAGE></p> |
