A dispenser (800) for dispensing oral care materials comprising: a housing (810) having a separator wall (805) forming a first reservoir chamber (830) containing a first oral care material (831) and a second reservoir chamber (840) containing a second oral care material (841) within the housing (810); a first nozzle (860) for dispensing the first oral care material (831) from the first reservoir chamber (830) and a second nozzle (865) for dispensing the second oral care material (841) from the second reservoir chamber (840), the first and second nozzles (860, 865) located on opposite ends of the dispenser (800); and wherein the first reservoir chamber (830) circumferentially surrounds the second reservoir chamber (840) about a longitudinal axis of the dispenser (800).

A collapsible portable container for mixing two substances comprising a first segment defining a first enclosed volume for housing a first substance, a second segment having side walls operably configured to collapse and defining a second enclosed volume for housing a second substance, a puncturing member disposed within the second enclosed volume, and a partition disposed in an interposing relationship between the first segment of the container and the second segment of the container, wherein the side walls of the second segment is operably configured to compress, thereby translating the puncturing member so as to pierce the partition and fluidly couple the first enclosed volume and the second enclosed volume.
