Title: Easy-to-remove handle of commercial tag
Inventor: MOTONAGA TOSHIFUMI
IPC: G09F3/14
Filed: 1994-03-27
Abstract: PURPOSE:To make the handle of a price tag easily removable without using tools, such as scissors by providing a part of the handle of this price tag with a part having a dent. CONSTITUTION:The part of the handle 1 of the price tag is provided with a part having the dent. The sectional area of the dent is formed smaller than the part near the dent. To remove the price tag 2, the user holds both ends of the dent and twists the handle by applying force in directions reverse from each other. The force by rotational moment acts as a force several tens of times as strong on the surface of the dent and the crack by shearing occurs on the surface. The handle can thus easily be cut off and removed. A large tensile force and a compressive force act on the dent and the dent is easily cracked even by the bending of the handle. The handle is cut and removed by properly and alternately repeating twisting and bending when the handle fails to be cut in spite of twisting. The part of the handle 1, if small, is provided with knob parts 5 at one or two points to facilitate holding by hands.
