PROBLEM TO BE SOLVED: To provide an extensible laminated adhesive tape capable of being easily extended without being peeled off a disposable article.SOLUTION: The extensible laminated adhesive tape includes a first tape piece, a second tape piece and a third tape piece, which are laminated in this order. The first tape piece has a free end at one end and a first joint end at the other end, and has a first joint part adjacent to the first joint end. The second tape piece has a first turnback part at one end and a second joint end at the other end, and the first turnback part is joined with the first joint part. The third tape piece has a second turnback part at one end and a third joint end at the other end. The second turnback part is joined with the second joint end, and at least part of the third joint end is joined with the first joint end. In the laminated adhesive tape, the region of the first joint end occupies 3-25% of the whole first tape piece, and the peel-off work at 180° of the laminated adhesive tape is 1-10 mJ.COPYRIGHT: (C)2013,JPO&INPIT【課題】 使い捨て物品から剥離することなく容易に伸展させることができる、伸展可能な積層粘着テープ。【解決手段】 両端部の一方に自由端部を、他方に第1接合端部を備え、第1接合端部に隣接する第1接合部を有する第1テープ片、両端部の一方に第1折り返し部を、他方に第2接合端部を備え、第1接合部と第1折り返し部とが接合している第2テープ片、及び両端部の一方に第2折り返し部を、他方に第3接合端部を備え、第2接合端部と第2折り返し部とが接合していると共に、第1接合端部と第3接合端部の少なくとも一部とが接合している第3テープ片を有し、第1テープ片、第2テープ片及び第3テープ片がこの順で積層される、伸展可能な積層粘着テープを提供する。積層粘着テープは、第1接合端部の領域が第1テープ片全体の3~25%であり、積層粘着テープの180°ピール剥離仕事が1~10mJある。【選択図】 図1
