1. A cosmetic container, comprising:
a threaded sleeve, wherein an inner wall of the threaded sleeve is provided with a first guide groove and a second guide groove forming a double helix;
a rotating member, rotatably sleeved in the threaded sleeve, wherein a side wall of the rotating member is provided with a hollowed-out slideway pattern, and the slideway pattern comprises at least a first slideway and a second slideway parallel with each other, the first slideway and the second slideway both extend axially and are connected with each other;
a material cup, slidably sleeved in the rotating member, wherein a side wall of the material cup protrudes outwardly to form at least one first lug, the first lug passes through the slideway pattern and is limited in the first guide groove, and the side wall of the material cup is provided with a third slideway extending axially; and
a pushing cup, slidably sleeved in the material cup, wherein a side wall of the pushing cup protrudes outwardly to form at least one second lug, the second lug passes successively through the third slideway and the slideway pattern and is limited in the second guide groove;
wherein when the rotating member is rotated relative to the threaded sleeve, the third slideway is successively overlapped with the first slideway and the second slideway, forming a first combined slideway for the pushing cup and the material cup to ascend and descend synchronously and a second combined slideway only for the pushing cup to ascend and descend;
wherein the first lug and the third slideway are arranged in a same axis; the first combined slideway comprises: the third slideway and a part of the first slideway that are overlapped with each other for the pushing cup to ascend and descend, and another part of the first slideway for the material cup to ascend and descend; the second combined slideway comprises the third slideway and the second slideway that are overlapped with each other;
wherein top of the first slideway is provided with a material cup upper locking position for preventing the material cup from ascending, and the material cup upper locking position is over the second slideway.
