以上のように構成してある本発明の粘着テープ
１においては、以下のような作用効果を有する。 The adhesive tape 1 of the present invention configured as described above has the following effects.
(1) 摘持部４は剛性が高いから、おむつの被接着
面に対して粘着部６を接着・剥離するときの摘
持操作が容易である。(1) Since the gripping portion 4 has high rigidity, the gripping operation when adhering and peeling off the adhesive portion 6 from the adhesive surface of the diaper is easy.
(2) 粘着部６は剛性が高い部分と低い部分とから
構成してあるから、おむつの腰回りを締め付け
て粘着部６をおむつの被接着面に接着すべく摘
持部４を指先で摘持して引張るとき、粘着部６
に指先部から放射状に波状の皺が派生すること
がなく、おむつの被接着面に対する粘着部６の
接着面が充分に確保される。(2) Since the adhesive part 6 is composed of a high-rigidity part and a low-rigidity part, the grip part 4 can be pinched with your fingertips in order to tighten around the waist of the diaper and adhere the adhesive part 6 to the surface of the diaper to be adhered. When holding and pulling, the adhesive part 6
No wavy wrinkles are generated radially from the fingertips, and a sufficient adhesive surface of the adhesive portion 6 to the adhesive surface of the diaper is ensured.
(3) 粘着部６は剛性の低い部分で折れ易いから、
おむつの被接着面に対する接着性（なじみ）が
良好になる。(3) Since the adhesive part 6 has low rigidity and is easily broken,
Adhesion (fitting) to the surface of the diaper to be adhered becomes better.
(4) 使用中におむつの被接着面と粘着部６との接
着面に力が加わつても、剛性の低い部分は折れ
曲がり易いから、その被接着面から粘着部６が
剥離しにくい。(4) Even if force is applied to the adhesive surface between the adhesive surface of the diaper and the adhesive portion 6 during use, the adhesive portion 6 is difficult to peel off from the adhesive surface because the portion with low rigidity is easily bent.
(4) 摘持部４を指先で摘持しておむつの被接着面
から粘着部６を剥離するとき、剛性の低い部分
は折れ曲がりやすいから、望ましい引張り角度
が自由にとれて剥離しやすい。ちなみに、剥離
するときの引張り力が最も軽くなる角度は大体
120゜前後であるが、その状態になりやすい。(4) When the adhesive part 6 is peeled off from the adhesive surface of the diaper by grasping the gripping part 4 with the fingertips, since the part with low rigidity is easily bent, a desired pulling angle can be freely set and peeling is easy. By the way, the angle at which the tensile force when peeling is the lightest is approximately
Although it is around 120°, it is easy to get into that state.
(5) 摘持部４と粘着部６の基材を不織布と熱溶着
性合成樹脂フイルムとにより構成してあるか
ら、両者を熱圧着で複合一体化しやすくかつ該
基材に適度の剛性を付与することができる。(5) Since the base materials of the gripping part 4 and the adhesive part 6 are composed of a nonwoven fabric and a heat-fusible synthetic resin film, it is easy to integrate the two into a composite body by thermocompression bonding, and the base material has appropriate rigidity. can do.
