Abstract
A scrub sponge comprising, a packet having a rupturable wall and a closed chamber containing a liquid scrub agent, and a cover of foam material having a cavity to receive the packet and enclosing the packet. The sponge has a puncture member intermediate the cover and the packet and having a pair of generally aligned and spaced arms on opposed sides of the packet beneath the cover, and hinge means connecting the arms adjacent one end of the packet. The puncture member has at least one sharp projection on each of the arms directed toward the packet to pierce the wall when the arms are pressed toward each other to release the scrub agent into the cover, and an opening extending through the arms adjacent each of the projections.
