发明名称 Marker tag for tree trunks and an applicator hammer for the application of same to tree trunks
摘要 A marker tag for tree trunks is provided with a flat element bearing indicia adapted to clip onto an applicator hammer. A nail extends perpendicularly through the flat element and is able to slide in a passage opening in the flat element preferably subject to the action of a clamping force and only able to be slid on application of a force. After driving the nail provided with the marker tag into a living tree trunk the trunk continues to increase in diameter and accordingly pushes the marker tag along the nail so that after a certain number of years it is stripped off and drops to the ground.
