Abstract: The present disclosure is concerned with a personal care device having an energy source arranged for being removable, the personal care device having an outer housing having a detachable closure element at one end, the detachable closure element enabling access to a cavity of the outer housing after detachment, a chassis disposed in the cavity of the outer housing, the chassis holding the energy source, the chassis having a blocking structure such as a charging coil holder positioned between the energy source and the closure element along an energy source removal direction, the energy source having a first electrical connector non-permanently coupled with a first electrical connector partner and a second electrical connector non-permanently coupled with a second electrical connector partner, the first electrical connector partner and the second electrical connector partner being secured at the chassis, the chassis being arranged for removal from the cavity of the outer housing along a chassis removal directio

Abstract: A cleaning implement. The cleaning implement has at least one nozzle to spray liquid onto a target surface, such as a floor. At least one light is provided. The light illuminates the spray, providing qualitative notice to the user where the spray occurs and qualitatively the amount of liquid dispensed. The spray and light may be concurrently activated by a common switch.

Abstract: The present disclosure includes a cartridge for a microfluidic delivery system. The cartridge has a longitudinal axis. The cartridge includes a reservoir for containing a fluid composition and a microfluidic delivery member connected with the reservoir. The microfluidic delivery member has a die having a nozzle and electrical traces that are in electrical communication with the die and terminate at electrical contacts. The die is in fluid communication with the reservoir. The cartridge includes an outer cover connected with the reservoir. The outer cover defines an interior and an exterior and includes an orifice that is adjacent to the nozzle. The outer cover at least partially covers the electrical contacts.

Abstract: A cartridge for a microfluidic delivery system is defined by a longitudinal axis. The cartridge includes a reservoir for containing a fluid composition. The cartridge also includes a nozzle operatively connected with the reservoir. The nozzle is in fluid communication with the reservoir for releasing the fluid composition. The cartridge includes an outer cover operatively connected with the reservoir. The outer cover comprises an orifice that is adjacent to the nozzle. An air flow path is formed by a gap between the reservoir and the outer cover.

Abstract: A personal hygiene device has a handle, a treatment head mounted for relative movement of at least a portion thereof with respect to the handle against a restoring force when a treatment force is applied in at least one direction onto the treatment head, a treatment-force-measurement unit for determining the applied treatment force comprising a light-emitting element, a light-sensitive element, and a light-changing element arranged at least partly in the light path between the light-emitting element and the light-sensitive element, wherein the light-changing element and at least one of the light-emitting element and light-sensitive element are arranged to be moved relatively to each other when at least the portion of the treatment head is moved.
