ABSTRACT:
A device (10) for marking the ground above a buried conveyance includes an upper and lower shells (12, 14) of a fracturable material joined at their edges to form a sealed body. A separator layer (16) devises the void between the two shells into an upper and lower regions (18, 20). The lower region contains a paint-adhesive mixture (22), whereas the upper region contains an indicia-bearing member (26) that identifies the entity responsible for the buried conveyance. To mark the buried conveyance, a technician deposits the marking device (10) on the ground and then steps on it, thereby fracturing the upper and lower shells to release the paint-adhesive mixture and the indicia-bearing member for adherence to the ground by the adhesive.
