Abstract: A method for storing, mixing, dispensing, and returning a fluid, a mixable composition and a resultant fluid meant for oral application includes the steps of providing a movable member within a cup-like container that isolates the mixable composition, containing the fluid about a portion of the movable member which isolates that composition, opening the container and displacing the movable member upwardly to concurrently mix the fluid and the mixable composition, accessing the resulting fluid for oral application by a user, and returning spent fluid to the container and closing the container. The method also may include the step of containing the discarded fluid separately.

Abstract: The container includes a housing with a liquid containment section, defined in part by a common wall, that holds the fluid. A movable member defines, in a first position and in conjunction with the common wall, a sealed interior chamber within which is disposed the mixable or solid composition. In a second position, the movable member is raised above the common wall thereby mixing the mixable composition and the fluid in a mixing section. The mixing section is a combination of the liquid containment section and the interior chamber. The container also includes a lid which is removably attachable to the housing and is operatively associated with the movable member such that when the lid is removed, the movable member is enabled to move from the first position to the second position. The container also includes a port for dispensing the resultant fluid derived from mixing the mixable composition and the fluid. The port is defined by the hollow body, movable member which has an open top and an open bottom.

Abstract: Orthodontic arch form of wire, or other resilient materials, and method of making same, having a compound elliptical shape wherein the form is generated by plotting three foci falling at the apices of an isoceles triangle and utilizing a string or the like in a closed loop of a length greater than the sum of the sides of the triangle to be restrained at the foci during the recording of the form by movement of a recording instrument restrained by the string.
