  • Patent number: 6220255
    Abstract: In a method for the manufacture of filler sticks for cosmetic sticks or the like, the filler stick being cast in a casing which is inserted in a mold, and the liquid casting compound rigidifying in the casing and in the mold, respectively, it is provided that the casing is housed in the holder at least with its lower end at an acute angle relative to the horizontal, that it can be filled from the free opposite end, the front of the lower end of the casing being followed by a closing portion, and the air displaced upon casting escaping through a vent, which extends outwards in the vicinity of the upper side of the lower front of the casing.

  • Patent number: 4899977
    Abstract: In a method and an apparatus for producing filler sticks for cosmetic sticks, in particular those having a swiveling mechanism for extending the filler sticks from a protective sheath, including a mold for casting the filler sticks, it is provided, in order to attain filler sticks that are optimally suitable for such swiveling mechanism and to attain a filler stick structure that assures favorable properties for use, that the filler stick is cast in a horizontally disposed mold recess open along at least a portion of its jacket face. For performing a method of this kind, an apparatus is used that is distinguished in that the mold has a plurality of horizontally disposed mold recesses, which are open along at least a portion of the jacket face, and that an expulsion device for the hardened, cast filler sticks is provided, acting in the axial direction of the mold recesses.

  • Patent number: 4748991
    Abstract: A powder compact material in the form of a stick for cosmetic purposes is made up of powder-like base materials and if necessary additions of binders, lubricants and materials increasing adhesion compacted or bonded together as a body which keeps its form. For stopping the end or outer face of the stick-like body becoming clogged with moisture and sebum on use (so that clean powder compact material would have to be uncovered by cutting, this wasting the material) the compact stick contains as part of the present invention, a particle material, whose particles are harder than the particles of the base materials. The hardness of the particle material may preferably be equal to at least 4.0 on the Mohs' hardness scale. A particle size of 10 to 50 microns and an outer face of the particles which as far as possible is jagged or otherwise rough is responsible for useful effects.

  • Patent number: 4332763
    Abstract: The invention makes available a cosmetic product in the form of a solid body, preferably a stick, which can be used as a cream by reason of its composition. The product is produced from a mixture of fatty substances, emulsifiers and water-soluble binders to which so much water is added that a mass of a mouldable consistency is obtained. By way of cold deformation, moulded pieces, preferably in stick form, are made therefrom and from these the water is subsequently extracted so that a solid structure is obtained.
