A recording medium containing cartridge comprises a first casing shell having a recess formed proximate a side wall thereof and a second casing shell matingly fitting with the first casing shell. The second casing shell has a projection formed at a location corresponding to the recess formed in the first casing shell. A dimension of a distal surface of the projection contacting a bottom of the recess is made less than a corresponding dimension of the bottom of the recess. This leaves a gap that safely accommodates a burr formed during a welding process that joins the casing shells together. First and second reels are rotatably mounted between the first and second casing shells and tape is wound therebetween.

A cartridge for containing a recording medium, said cartridge comprising: a rectangular first casing shell having a first planar portion, a first side wall mounted on said planar portion and having a first side wall portion substantially perpendicular to a first adjacent side wall portion, and four recesses formed in said first planar portion proximate said first side wall at respective corners of said first casing shell, each of said recesses having a first predetermined width, at least one of said recesses having a first recessed extension substantially parallel to said first side wall portion and a second recessed extension substantially parallel to said first adjacent side wall portion with said first and second recessed extensions converging substantially perpendicular to one another, said first side wall having an edge opposite said first planar portion, said edge forming a first abutment surface; a rectangular second casing shell having a second planar portion and a second side wall including a second abutment surface engageable with said first abutment surface and having a second side wall portion substantially perpendicular to a second adjacent side wall portion, said second casing shell having four projections formed on said second planar portion at locations corresponding to said four recesses, each of said four projections having a length extending beyond said second side wall and having a contact surface at an extreme end thereof furthest from a point of attachment of said projections to said second casing shell, each said extreme end having a second predetermined width less than said first predetermined width, at least one of said projections having a first projection extension substantially parallel to said second side wall portion and a second projection extension substantially parallel to said second adjacent side wall portion with said first and second projection extensions converging substantially perpendicular to one another, wherein each said contact surface is joined by welding to a bottom surface of a respective one of said recesses for connecting said first casing shell and said second casing shell with said contact surface of said at least one of said projections being joined by said welding to said bottom surface of said at least one of said recesses, a difference between said second predetermined width and said first predetermined width defining a gap between an outer side surface of each said extreme end of each said projection and an inner side surface of each respective said recess when each said projection is inserted in each respective said recess during joining of said first and second casing shells, wherein a burr comprising excess material of each said protection is formed on each said projection when each respective said extreme end is melted during said welding and said burr wholly resides in said gap; and said first and second casing shells enclosing a space for accommodating the recording medium.
