Abstract
A rod-shaped cosmetic material feeding container includes a tubular-shaped container with a front part and a rear part, a movable body with a male thread at an outer peripheral part, and supporting a rod-shaped cosmetic material at a distal end, and a female threaded member with a female thread at an inner peripheral part. First and second elastic bodies each accumulate resilient force and have different spring constants. The male thread and the female thread constitute a threaded engagement mechanism that, by relative rotation between the front part and the rear part, advances and retracts the movable body and causes the rod-shaped cosmetic material to appear and disappear from an opening of the container. The first elastic body is sandwiched between the rear part and the female threaded member and the second elastic body is sandwiched between the front part and the female threaded member.
