Application No. 08/059,840
1. A recording medium cartridge comprising:
a casing in which a recording medium is received;
said casing comprising an upper casing member and a lower
casing member jointed to each other;
said upper and lower casing members being made of
crystalline resin and jointed together by welding;
said crystalline resin having a filler which permits said
crystalline resin to exhibit improved welding properties
incorporated therein, said filler constitutes 10 percent to 30
percent by weight of the crystalline resin mixture.
15. In a recording medium cartridge formed from a pair of
molded casing members that are welded together by ultrasonic
energy, the improvement comprising:
each casing member is formed from a crystalline resin and a
filler material, the filler material having a characteristic of
increasing the ultrasonic welding properties of the molded casing
member;
a plurality of projection members extend from one surface of
each molded casing member and are respectively aligned when the
respective casing members are contacted together for welding; and
means, indented on the other surface of at least one casing
member is provided to receive a welding horn, for transmission of
an application of ultrasonic energy to the contacted surfaces of
the projection members.
