Abstract: In one aspect, a dispenser is provided herein for dispensing flowable material, such as sunscreen lotion, including a resiliently deformable body encompassing a closed volume with an optional flexible pouch disposed therein to accommodate the flowable material. A discharge element is also provided having at least one discharge opening, along with at least one valve regulating flow from the closed volume or the flexible pouch and through the discharge opening. The body is configured so that a threshold amount of deformation of the body causes the flowable material to urge from the closed body through the discharge opening or the pressure increase of the closed volume acting on the flexible pouch sufficiently so that flowable material accommodated in the flexible pouch is urged therefrom through the discharge opening. Advantageously, the dispenser of the subject invention allows for a generally isobaric environment to be created which acts evenly about the flexible pouch.

Abstract: In one example, a modified electrical device includes a body and at least one connector on the body to make power and control connections with an active cover plate. In some embodiments, a wall plate system may include a modified electrical device or receptacle and/or an active cover plate.
