<p>PROBLEM TO BE SOLVED: To remove from a cassette-holding case packaged in film an angular part to be placed in contact with the packaging film for eliminating rupture of the film caused by an impact, shaking, etc., in the stage of distribution following the packaging in film. SOLUTION: A holding case having an opening 12 for inserting a cassette opening in opposition to a backboard 2 is formed of a sheared sheet to a pattern and put together as a box of rectangular parallelepiped or cube having a front- side board 1, the back board 2, and a back-side board 3 in continuation as demarcated by bending lines 5 and having along the two ends of each of these three board 1, 2, 3 front-side board flaps 9, back board flaps 10, and back-side board flaps 11 all forming two-side boards in continuation as demarcated by bending lines 6, 7, 8. In this instance the length of the front- and back-side boards 2, 3 to the extend from the above-mentioned opening 12 to the back 1 is shorter than that of the tape cassette A, so that in the stage of distribution following the packaging of the cassette-holding case on film is does not occur for the film to rupture due to an impact, shaking, etc. Then the package can be handled safely and the holding case feels soft to the touch and is kept from injuring a finger, etc.</p> |
