    • The present invention provides an easy-to-produce PTP which exhibits good hermetic sealing performance and which can be readily and reliably opened (without variation) even if the working accuracy is reduced, and also provides its production method. The PTP includes a lid member 3 having a resin film 3a, an aluminum foil 3b, and a thermal adhesive layer 3c, and a container 5 having a flange portion 5b and a large number of pocket portions 5a. The resin film 3a is provided with a plurality of cut pattern units constituting weakening point-cuts 3h arranged in a string 3j. The pitch P1 of the weakening point-cuts 3h along the string is smaller than the pitch of the pocket portions, and at least one of the weakening point-cuts or at least a part of the weakening point-cut falls within a position corresponding to each of the pocket portions.
    • 本发明提供一种易于生产的PTP,即使加工精度降低,其表现出良好的气密密封性能并且可以容易且可靠地打开(无变化),并且还提供其生产方法。 PTP包括具有树脂膜3a,铝箔3b和热粘合层3c的盖构件3和具有凸缘部分5b和多个袋部分5a的容器5。 树脂膜3a设置有构成以串3j排列的弱点切割3h的多个切割图案单元。 沿着弦的弱点切割3h的间距P1小于袋部的间距,并且弱化点切割中的至少一个或弱化点切割的至少一部分落入对应于 每个口袋部分。
