1. A one-hand lipstick container, comprising:
a cylindrical main body extending in an axial direction;
a cover holder rotatably received on an outer circumferential surface of the cylindrical main body via a first screw mechanism therebetween;
a cover hinged to the cover holder to open and close an opening at an upper end of the one-hand lipstick container;
a lipstick housing rotatably received on an inner circumferential surface of the cylindrical main body via a second screw mechanism therebetween,
wherein the first screw mechanism and the second screw mechanism have opposite rotational directionalities to each other;
an intermediate member interposed radially between the cylindrical main body and the lipstick housing, the intermediate member including a head and a guide sleeve extending from the head,
wherein the head slidably engages with the cover holder to limit rotation of the cover holder relative to the intermediate member while allowing the cover holder to move in the axial direction relative to the intermediate member,
wherein the guide sleeve slidably engages with the lipstick housing to limit rotation of the lipstick housing relative to the intermediate member while allowing the lipstick housing to move in the axial direction relative to the intermediate member;
an upper case affixed to the intermediate member;
a bottom case affixed to the cylindrical main body; and
a cover guide attached to the head of the intermediate member, the cover guide including a cover guide groove along which the cover is guided,
wherein some of a plurality of recesses on the head of the intermediate member are aligned with and not inserted into some of a plurality of projections on the cover guide and one projection on the cover guide is inserted into one recess on the head of the intermediate member to secure the cover guide in place relative to the head of the intermediate member,
and
wherein a dimension of the cover guide is equal to or smaller than a gap between opposing surfaces of the upper case and the head of the intermediate member, such that the cover guide is fixed in place between the upper case and the head once the one-hand lipstick container is assembled.
