A cosmetic dispenser with an inner body rotatably engaged with a spiral member. An elevator cup retains a cosmetic pomade, and the spiral member has spiral formations along an inner surface thereof for engaging lugs of the elevator cup that pass through longitudinal tracks in the inner body. The inner body can have lateral and longitudinal bearing surfaces with the lateral bearing surface aligned longitudinally with a longitudinal axis of relative rotation of the spiral member and the inner body and the longitudinal bearing surface orthogonal thereto. Fingers can project inwardly from the inner body to be in slidable, frictional contact with both the longitudinal and lateral bearing surfaces so that the fingers are restrained laterally and longitudinally. The fingers can be inwardly angled establish an effective circumference with the fingers tangent thereto smaller than the circumference of the lateral bearing surface.

A cosmetic dispenser with an inner body, an outer body, and an elevator cup has a rotary extension and retraction mechanism, a first annular bearing surface retained relative to the inner or outer body and an annular wall retained relative to the other of the outer or inner body. The annular wall can be a skirt of the outer body and can be crenelated into arcuate merlons and crenels. The merlons establish an effective circumference that overlaps with the circumference of the first annular bearing surface to provide frictional resistance to a rotation of the inner body relative to the outer body. The merlons can surround the first annular bearing surface and establish a circumference smaller than the circumference of the first annular bearing surface. The annular bearing surface can be a lateral bearing surface, and a second annular bearing surface can form a longitudinal bearing surface.

The invention provides a hollow raised fabric and a preparation method thereof. The hollow raised fabric includes a surface layer, a hollow layer and a bottom layer, the surface layer and the bottom layer are connected through the hollow layer; the bottom layer is composed of a first coil and a second coil, and the yarn count of the first coil is lower than that of the second coil; the bottom layer is raised by steel needles, And in raised finishing, the first loop is elongated to protrude from the surface of the substrate. The first loop in the bottom layer of the hollow raised fabric protrudes from the bottom surface, which has the characteristics of easy to grasp, dense hair effect, and excellent hair effect reproducibility, and will not touch the polyester yarn of the hollow layer when raising, and will not damage the structure of the hollow layer. It not only solves the problem that traditional knitted air layer fabric is difficult to fluff, but also feels fluffy after washing, has good resilience, keeps shape and keeps warm, and will not become thinner with washing like ordinary plain terry raised fabric, which improves the warm life of raised fabric.
