A break-open single-dose package includes a panel defining a frangible region, one or more sheets coupled to the panel and defining a pocket therebetween for storing a spreadable consumable, and an applicator. The frangible region is adapted to form an opening through which the spreadable consumable can exit in response to folding of the panel. The applicator includes a backing and a vessel extending from the backing. The vessel defines a channel for receiving any spreadable consumable that exits the pocket. The applicator is positioned adjacent to the frangible region for permitting a user to spread on a surface any spreadable consumable that exits the pocket using the applicator without requiring the user's hand(s) to contact the spreadable consumable. The backing is configured to move with the panel and separate from the vessel in response to folding of the panel. Other example packages and/or applicators are also disclosed.

A color tray includes a first paint compartment configured to hold a first paint color; a second paint compartment configured to hold a second paint color, wherein the first and second paint compartments converge at a convergence point; and a bristle divider that partitions the first paint compartment from the second paint compartment, the bristle divider being ramped downward toward the convergence point such that a height of the bristle divider decreases toward the convergence point.

A system for mixing two cosmetic products includes a tubular bottle defining a first reservoir containing a first product to be mixed, a tubular cartridge defining a second reservoir containing a second product to be mixed, a retaining device suitable for retaining the cartridge on the bottle in an injection position in which the first reservoir communicates with the second reservoir via the inlet orifice of the base and the injection orifice of the cartridge, a perforator having an upper edge designed to perforate the cap that seals the inlet orifice when the cartridge occupies the injection position, and a piston that seals the lower end of the cartridge and that is axially slidably mounted between an initial bottom position and a final top position in order to push the second product through the injection orifice from the second reservoir to the first reservoir.

An apparatus for preparing a cosmetic composition containing an emulsion substance formed by instant emulsification through a microfluidic channel is provided. The apparatus includes a housing defining the appearance of the apparatus and installed with a pump on one side, the pump being operated by a user; an external-phase chamber provided in the housing, and storing an external-phase fluid forming the external phase of the emulsion substance; a dispersed-phase chamber provided in the housing, and storing a dispersed-phase fluid forming the dispersed phase of the emulsion substance. The apparatus further includes a microfluidic channel providing a path for the external-phase fluid and the dispersed-phase fluid to flow for forming the emulsion substance by combining the external-phase fluid with the dispersed-phase fluid; and a tube for discharging the emulsion substance from the microfluidic channel.

A refill for a device for treating hair, including: a reservoir of elongate shape along a longitudinal axis, defining a cavity containing a cosmetic composition to be applied to the hair, the reservoir having a flank for mounting the refill on the device, extending parallel to the longitudinal axis of the reservoir, a porous application member for applying the cosmetic composition to the hair, of elongate shape and extending parallel to the longitudinal axis of the reservoir. The application member being fitted in a slot-shaped opening in the reservoir that leads into the cavity, this opening being offset laterally toward the mounting flank, relative to a median plane of the cavity that contains the longitudinal axis of the reservoir and is parallel to the mounting flank.

A cosmetic source applicator is provided for users to decorate skin and/or place at least one skin product in contact with recipient skin. It may comprise one or multiple containers and one or multiple interchangeable cartridges. Each container provides secure support of one cartridge during skin decoration use over an open-topped bottom recess. A cartridge may hold, store, or be the cosmetic source, and be constructed in one or multiple sizes, shapes and/or materials. Each cartridge also has opposing top and bottom surfaces which may be reversed in positioning for skin decoration successively by both surfaces. Containers may attach to another container for increased ease in reaching different areas on the body. For convenient storage and travel, containers may store a cartridge before, during and after use. The cosmetic source applicator's use of single-use cartridges, disposable cartridges, and multi-use cartridges limit cartridge exposure to bacteria and other environmental germs.

An apparatus for producing a composition includes a holding device for holding first and second capsules including first and second deformable compartments, respectively, which contain a first formulation and a second formulation, respectively; a first compression element including a first compression surface designed to apply a pressure to the first deformable compartment of the first capsule; and a second compression element including a second compression surface designed to apply a pressure to the second deformable compartment of the second capsule. The first compression surface is designed to conduct and guide the contents of the first capsule to a first passage in the first capsule that can be fluidically connected to the first deformable compartment and the second compression surface is designed to conduct and guide the contents of the second capsule to a second passage in the second capsule that can be fluidically connected to the second deformable compartment.
