Case with a reinforced bottom

Abstract

A case includes a bottom shell member and a main shell member. The bottom shell member is made of a rigid material, and includes a bottom wall and a peripheral wall extending upwardly and integrally from a periphery of the bottom wall. The main shell member includes a hollow case body and a panel body. The case body has a lower portion that is connected fixedly to the peripheral wall such that the case body cooperates with the bottom shell member to form a receiving space of the case, and is formed with an access opening that permits access into the receiving space. The panel body is connected movably to the case body so as to permit closing and opening of the access opening.

1 . A case comprising:
