PROBLEM TO BE SOLVED: To provide a clam shell pack which can be quickly and easily unsealed, and in addition, can rehouse a content, and can be reused as a case in the clam shell pack which houses the content 2 between a pair of clam shells lA and lB and is sealed. SOLUTION: This clam shell pack has a structure wherein a pair of the clam shells lA and 1B are partially bonded by a method such as heat-welding at specified locations on the outer peripheral parts, and sealed. In the structure, a perforation groove 13 is formed in a manner to surround the bonded areas 12 of the clam shells. At the time of unsealing, the clam shell pack can be quickly and easily unsealed by breaking the part of the perforation groove 13, but parts other than the perforation groove 13 are not broken. Then, the clam shells after being unsealed can rehouse a content by being held under a joined state by the fitting part 11 of a recess 11a and a protuberance 11b, and can be utilized as a case.
