Patent ID: 8915664

Claim:
A complete exhaustion type lipstick tube, comprising a base, an outer-layer spiral tube with internal thread, a middle-layer involution tube with a longitudinal groove, and a fixed cup arranged on the inner side for setting lipstick, are sequentially sheathed on the inner side of the base from outside to inside, the outer-layer spiral tube and the middle-layer involution tube can rotate relatively, the bottom of the middle-layer involution tube is fixed in the base, the fixed cup can move up and down along the middle-layer involution tube during rotation, wherein the fixed cup is a separated fixed cup and formed by sheathing a cup wall on the outer side and the base plate on the inner side, wherein, a vertical groove is arranged on the cup wall a first lifting point is arranged directly under the vertical groove, and the first lifting point penetrates the longitudinal groove of the middle-layer involution tube and is embedded in an internal thread of the outer-layer spiral tube; a second lifting point is arranged on the outer surface of the base plate, the second lifting point penetrates the vertical groove of the cup wall and a longitudinal groove of the middle-layer involution tube and is embedded in the internal thread of the outer-layer spiral tube, the second lifting point is longitudinally stacked with the first lifting point of the cup wall at the bottom of the vertical groove of the cup wall and can move up and down along the vertical groove, and a lipstick fixing part is arranged on the base plate; the outer-layer spiral tube is divided into an upper section and a lower section, the width of the internal thread of the lower-section spiral tube is sufficient to enable the first lilting point and the second lifting point, which are longitudinally stacked, to move side by side, and the width of the internal thread of the upper-section spiral tube can only enable the second lifting point to move alone; by relatively rotating the lower-section spiral tube and the middle-layer involution tube, the first lifting point of the cup wall and the second lifting point of the base plate can ascend simultaneously along the longitudinal groove on the middle-layer involution tube, the fixed cup is upwards pushed out of the inside of the middle-layer involution tube till the second lifting point is sent into an inlet of the internal thread of the upper-section spiral tube, then the first lifting point stays at the top of the internal thread of the lower-section spiral tube, and then the fixed cup achieves the highest point; by further relatively rotating the upper-section spiral tube and the middle-layer involution tube, the second lifting point of the base plate can ascend along the vertical groove of the cup wall, and then the base plate is upwards pushed to a top portion of the inside of the cup wall.
