Storage case for tape cassette

A storage case for a tape cassette, comprising:

• a lower casing portion substantially allowing insertion of a lower shell portion of said tape cassette;
• an upper casing portion substantially allowing insertion of an upper shell portion of said tape cassette;
• a hinge member connecting said lower and upper casing portions;
• a plurality of hub base portions protected from an inner surface of one of said lower and upper casing portions;
• and
• a cylindrical cap member attached respectively over each of said hub base portions, each cap member including:
• a tapered annular outer wall having a diameter at a lower side thereof which is greater than that of an upper side thereof;
• and
• a flat upper surface portion formed integrally with said outer wall;
• wherein a thermal expansion coefficient of a material of said cap member is the same or less than that of a material of which reel portions of said tape cassette are formed, and wherein an engaging member interlocking with a receiving portion of said hub base portion is provided at a lower side of said flat upper surface so as to prevent rotation of said cap member relative to said hub base portion.

A storage case for a tape cassette, comprising:

• a lower casing portion substantially allowing insertion of a lower shell portion of said tape cassette;
• an upper casing portion substantially allowing insertion of an upper shell portion of said tape cassette;
• an elongate hinge member connecting said lower and upper casing portions;
• a plurality of hub base portions projected from an inner surface of one of said lower and upper casing portions;
• and
• a cylindrical cap member attached respectively over each of said hub base portions, each cap member being integrally formed and including:
• tapered annular outer wall having a diameter at a lower side thereof which is greater than that of at upper side thereof, a taper angie of said tapered outer wall portion being 2.degree. or less;
• a flat upper surface portion having a plurality of openings provided therethrough;
• an engaging member interlocking with a receiving portion of said hub base portion is provided at a lower side of said flat upper surface portion so as to prevent rotation of said cap member according to installation thereof;
• an annular retaining flange formed at said lower side of said tapered outer wall portion engaging a corresponding annular recess formed around said hub base portion;
• a annular beveled outer wall portion is provided between said tapered outer wall and said flat upper surface portion;
• a resilient member disposed around said outer wall portions;
• and wherein
• a thermal expansion coefficient of a material of said cap member is the same or less than that of a material of which reel portions of said tape cassette are formed.
