PROBLEM TO BE SOLVED: To provide a PTP (press-through pack) the lid of which can easily be prevented from being damaged when the PTP is carried or stored and which can be generated easily.SOLUTION: The press-through pack 2 includes: a container body 3 obtained by recessing one side of a base material sheet to form concave parts 20 for housing an object 60 to be packed and a lid 4 for closing the recessed surfaces 22 of the concave parts 20. A housing 10 being an area where the concave parts 20 are formed and an extended part 30 extended from the housing 10 are formed. A bent part 40 is formed in a boundary between the housing 10 and the extended part 30 by bending the lid 4 inward. When the lid is bent at the bent part 40, an engagement structure for making the housing 10 engaged with the extended part 30 is formed. The engagement structure comprises notch lines 12, 32 formed at the ends 11, 31 of the housing 10 and the extended part 30, respectively.COPYRIGHT: (C)2013,JPO&INPIT【課題】携行時や保管時に蓋体が破損するのを容易に防止でき、かつ容易に製造できるPTPを提供する。【解決手段】基材シートの一方の面に開口し被包装物60を収容する凹部20が形成された容体3と前記凹部20の開口面22を塞ぐ蓋体4とを備え、前記凹部20が形成された領域である収容部10と該収容部10に延設された延設部30とが形成され、前記収容部10と前記延設部30との境界に前記蓋体4を内側にして折り曲げる折曲部40が形成され、前記折曲部40で折り曲げられた際に、前記収容部10と前記延設部30とを係合する係合構造を備えるプレススルーパック2において、前記係合構造は、前記収容部10及び前記延設部30のそれぞれの端部11、31に形成された切込線12、32であることよりなる。【選択図】図1
