<p>PURPOSE:To improve the strength of fusion attachment of the pocket in a tape cassette-holding case in which a pocket allowing a description card to be inserted and extracted is attached by thermal fusion inside by forming the case as one having at least the part of the fusion welding of the pocket as the contents. CONSTITUTION:A case 31 for holding a video tape cassette is composed of a case body 32 having a cassette-placing opening 32a and a lid 33 which is connected to the case body 32 with a common wall in between and opens and closes the cassette-placing opening 32a. The lid 33 consists of a box-shaped body having as the contents at least the part of the fusion welding of an inside pocket 44 to insert a description card 45 in and extract it from. The ceiling- forming side 34 of the lid 33 holds as the contents the fusion welding part 40 of the pocket, which is substantially L-shaped in plane figure and extends from the back end edge to the left end edge. Except the part with the fusion welding part 40, the main part 41 is made a free ceiling-forming side. The inside pocket 44 is formed of transparent plastic sheet and provided by thermal fusion on the inside bottom 40a at the position of the fusion welding part 40 of the pocket.</p> |
