Abstract: The disclosed technology includes dispensing systems, devices, and methods. The dispensing systems include a plurality of sealing components, and a plurality of coupling mechanisms. In one embodiment, a dispensing device, including a first unit having a top wall and an inner cylindrical projection extending from a bottom face of the top wall and a second unit having an outer cylinder, is adapted to be received by a receptacle. The inner cylinder receives the inner cylindrical projection and the outer cylinder receives the receptacle. A breakable seal closes an opening of the inner cylinder to form a chamber portion for storing a substance. Protruding seals on the inner cylindrical projection bear on the inner cylinder. An application of force to the top wall lowers the inner cylindrical projection to disrupt the breakable seal and release the substance into the receptacle to mix with a liquid stored in the receptacle.

Abstract: A drain cover and drain cover system are disclosed. The drain cover includes a flange portion that rests on a bottom of a body designed for use with running water, such as a bathtub or shower. The drain cover overlays a drain on the body to prevent water from going down the drain until the water exceeds a predetermined height in the body. Further, the drain cover does not require fasteners to maintain it in place, instead relying upon hydrostatic pressure applied to the drain cover by the water and friction between the drain cover and the body.
