Abstract: A plastic carrying case is disclosed along with the method of manufacture and the mold tool. The carrying case is particularly suited for transporting and storing a fishing rod and reel, and is comprised of two plastic members which may be interlocked by a snap fit. A first plastic member includes an elongated tubular section to receive a rod and an enlarged, essentially tubular section to receive the reel. A second plastic member includes an enlarged, essentially tubular section having snap-fit interlocking surfaces which cooperate with complementary surfaces on the enlarged section of the first member to maintain the two plastic members in interlocked relationship when desired. The method of manufacture includes extruding a tube of thermoplastic material between the opened sections of a blow mold, closing the molds, and inflating the tube to a blown product conforming to the shape of the internal mold cavity.
