<p>The invention relates to a complete exhaustion type lipstick tube, an outer-layer spiral tube, a middle-layer involution tube and a fixed cup arranged on the inner side for setting lipstick are sequentially sheathed on the inner side of a base from outside to inside, and a longitudinal groove is arranged on the tube wall of the middle-layer involution tube; in the fixed cup, a vertical groove is arranged on the cup wall and the tube 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 the internal thread of the outer-layer spiral tube; a second lifting point is arranged on the outer surface of a base plate, and the second lifting point penetrates the vertical groove and the longitudinal groove and is embedded in the internal thread; and 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 lifting point and the second lifting point 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. The complete exhaustion type lipstick tube has the advantages that the original integrated type fixed cup is changed to the split type, the outer-layer spiral tube is changed to the two-section type, when the lipstick which is exposed on the fixed cup is exhausted, the lipstick on the inner side of the fixed cup can be further pushed out till complete exhaustion.</p> |
