Abstract:
A powder applicator includes a reservoir for powder and a porous membrane tensioned over the reservoir. A portion of the powder is stored in the vicinity of the membrane, in a very open synthetic foam pad between the reservoir and the membrane and communicating with the reservoir.
Abstract:
Disclosed is a cosmetic powder applicator. The powder applicator includes a powder container, an elastic structure connected to the container and a powder-permeable soft cover enclosing the elastic structure. The structure has an elasticity sufficient to substantially bend upon application of pressure thereto and to substantially recover an original shape thereof upon release of the pressure. The soft cover is so configured as to retain therein and pass powder particles through itself. The powder applicator is configured such that, by turning or shaking the applicator, the powder to be contained in the container can be discharged through the discharge opening toward the soft cover and the structure enclosed therein. Further disclosed is methods of making and using the powder applicator. The method of making includes a feature of connecting the elastic structure enclosed in the soft cover with the container such that the powder to be contained in the container can be discharged through the discharge opening toward the structure and the soft cover. The method of using the powder applicator includes a feature of contacting the soft cover with a skin, applying pressure onto the soft cover and the elastic structure thereunder such that the structure is substantially bent while maintaining structural rigidity thereof and releasing the pressure so as to allow the structure to recover an original shape thereof. The powder retained in the soft cover is transferred to the skin in the course of one or more of the contacting with the skin, and the application and release of the pressure.
Abstract:
A device for at least one of applying a product to a surface and packaging a product may include at least one element that may include at least one substance, and at least one of the product and the surface receiving the product may be enabled to contact the at least one substance. Alternatively, or in addition, the at least one element may generate at least one of an electric field and a magnetic field, and at least one of the product and the surface may be enabled to be subjected to the field generated by the at least one substance. Other devices as well as methods are also disclosed.
Abstract:
A vacuum chamber deposits thin films on a substrate by sputtering a target. The beam of atoms or ions from the target is partially blocked by a shadow or adjustable uniformity mask, reducing the deposition rate onto the substrate. The adjustable uniformity mask has several adjustable fingers. The fingers extend or retract to enlarge or reduce the size of the mask. Each finger covers a different annular region or radius of the substrate. The deposition rate at different substrate radii is thus adjustable by the fingers. Several optical beams monitor the film transmittance at different substrate radii. A transmittance profile is continually generated during deposition. As deposition proceeds, radii with a thicker film have their fingers extended to reduce their deposition rate, producing a more uniform film thickness across all radii. Motors extend or retract the individual fingers.
