Claim:
A clam shell type receptacle comprising: a case assembly including a bottom case and a top case, the bottom case having a bottom wall and a peripheral wall which together form a recessed reception space, and the top case having a top wall and a peripheral wall which together form a recess, the top case being coupled to the bottom case so as to open or close the reception space, and the top wall having a button opening formed at the central area thereof; and a locking and release unit for locking the reception space in a closed state and for releasing the reception space from a locked state, the locking and release unit comprising: a button engaged with the top case in such a manner that one end of the button can be moved toward the bottom wall through the button opening when the button is pressed toward the bottom wall; a catch wall vertically formed on the bottom wall so that the catch wall is arranged between the moving end of the button and the peripheral wall of the bottom case, the catch wall having a catch groove at a surface opposite to the peripheral wall of the bottom case; an actuation member having a head and a leg extending from the head, the leg having a locking projection formed at a longitudinal end thereof, the actuation member being installed within the case assembly in such a manner that when the button is pressed, the head is moved toward the peripheral wall of the bottom case, and when the head is moved toward the peripheral wall of the bottom case, the locking projection is released from the catch groove; and an elastic return member interposed between the actuation member and the case assembly so that when the head is moved toward the peripheral wall of the bottom case, the elastic return member accumulates elastic force, wherein the elastic return member comprises a pair of elastic return arms formed on the opposite lateral sides of the head and extending away from each other, the elastic return arms being supported by the top case so that they accumulate elastic force when the head is moved toward the peripheral wall of the bottom case.
