    • PROBLEM TO BE SOLVED: To provide a patch that suppresses large exposure of an adhesive face by a small stress before use and easily divides a release liner during use.SOLUTION: The sheet-like patch 1 is equipped with an adhesive layer 20 on one side of a substrate 10, an adhesive face 20a exhibiting adhesion and a release liner 30 for covering the adhesive face. The liner has a parting line alternately equipped with cuts 31 and connected portions 32, is divided by cutting the connected portions along the parting line by turns and a first area is released from the adhesive face before a second area while performing the cuttings of the connected portions. In dividing, a connected portion between one cut at the upstream side in a division direction and another cut to be adjacent to the cut at the downstream side is cut in a form to connect the downstream side end part of the one cut to the middle part from the upstream side end part to the downstream side end part of the another cut and the upstream side end part is positioned closer to the first area side than the downstream side end part.
    • 要解决的问题:提供在使用前通过小的应力抑制粘合剂面的大的暴露的贴片,并且在使用期间容易地分离剥离衬垫。

      解决方案:片状贴片1在基底10的一侧上装有粘合层20,具有粘合性的粘合面20a和用于覆盖粘合面的剥离衬垫30。 衬垫具有交替配备有切口31和连接部分32的分型线,通过沿分型线迂回切割连接部分并在第二区域之前从粘合面剥离第一区域,同时执行连接的切割 部分。 在分割时,分割方向上游侧的一个切口与下游侧的切口相邻的切口之间的连接部分被切割成将一个切口的下游侧端部与中间部分 从另一个切口的上游侧端部到下游侧端部,并且上游侧端部位于比下游侧端部更靠近第一区域侧。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a patch preparation having an actual area of the preparation not larger than the effective area of the preparation necessary for drug releasability, which hardly causes end edge lifting when taking the preparation out from a package, and enables easy detachment of a preparation body from a release liner when in use.SOLUTION: The patch preparation includes the preparation body where an adhesive layer containing a drug is formed on one entire surface of a support, and the release liner laminated on the adhesive layer to cover the entire exposed surface of the adhesive layer of the preparation body. The preparation has a central part and a peripheral part surrounding the central part, and release force between the adhesive layer and the release liner in at least a part of the peripheral part is greater than release force between the adhesive layer and the release liner in the central part.
    • 要解决的问题:提供具有不大于药物释放性所需制剂的有效面积的制剂的实际面积的贴剂,其在从包装中取出时几乎不引起末端提起,并且能够容易地脱离 的制剂本体,其在使用时由剥离衬垫构成。解决方案:贴剂制剂包括制剂体,其中在载体的整个表面上形成含有药物的粘合剂层,并且将剥离衬垫层压在粘合剂层上以覆盖 制剂主体的粘合剂层的整个暴露表面。 制剂具有围绕中心部分的中心部分和周边部分,并且在周边部分的至少一部分中,粘合剂层和剥离衬垫之间的释放力大于在粘合剂层和剥离衬垫之间的释放力 中央部分。
