Abstract
A package assembly (20) comprises products enclosed in a tubular packet (24) formed from a flexible wrapper (26). A line of weakness (40) encloses an opening region (42) in a side wall (28) of the packet. The opening region (42) is at least partially removed to create a dispensing opening by tearing the wrapper along the line of weakness (40). In one embodiment, the packet is opened by pressing one of the products through the opening region. In another embodiment, a sticker (150, FIG. 3) is adhered to the opening portion to provide a tab (152, FIG. 3) which can be pulled to open the packet. In a further embodiment, the packet is enclosed in a stiff outer cover (260, FIG. 5). The cover has a reclosable flap (262) bonded to the opening region so that on first opening of the flap, the packet is torn along the line of weakness.
