This disclosure is concerned with a personal care device with a treatment head being pivot-mounted around a pivot axis, the personal care device having a pin having a pin head, a cam element having a cam surface, a spring element biasing the pin head and the cam surface against each other, wherein the cam surface is shaped such that it defines a rest position at which the biasing spring force provided by the spring element with which the pin head and the cam surface are pushed against each other has a non-zero minimum value, and wherein a pivoting of the head around the pivot axis causes the pin head to move along the cam surface and the cam surface is further shaped such that the spring force pushing the pin head and the cam surface against each other increases with increasing pivoting angle.

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.

Battery operated appliances are provided. Some appliances include a housing defining a chamber having an interior wall, electronics within the chamber, a battery cover, and a closing system including (a) a first electrically conductive member secured to the battery cover, and (b) a second electrically conductive member secured to the interior wall of the housing and configured to engage the first electrically conductive member and thereby mechanically secure the battery cover to the housing while also establishing electrical contact between the first and second electrically conductive members.

Battery-operated razor

Water-tight battery powered appliances, for example personal care appliances such as razors and toothbrushes, are provided. The appliances include a housing having a seal that allows gases, e.g., hydrogen, to vent from the appliance without allowing water to enter.
