ABSTRACT:
A pull-activated container adapted to hold a fluid, volatile solid, or absorbent for a fluid wherein at least a portion of the container includes a laminate which, in turn, includes a first layer, a second layer, a third layer, and a grasping means. The first layer is a fibrous sheet, the second layer is a film having a first side and a second side, and the third layer is a porous fibrous sheet. The third layer is inside the container. The first layer is bonded to the first side of the second layer and has a first bonding strength and the third layer is bonded to the second side of the second layer and has a second bonding strength. For example, the first bonding strength may be greater than the second bonding strength to an extent sufficient to permit selectively removing the first and second layers from the third layer without tearing the third layer. The grasping means is affixed to the first layer and has a third bonding strength which is greater than the second bonding strength. If desired, a portion of the first layer may be defined by lines of weakness sufficient to aid in removing such portion at least partially from the third layer. Desirably, the grasping means will be attached to the portion of the first layer which is defined by lines of weakness.
