Abstract: A container includes a housing for containing an O2-generating composition. The housing includes a venting layer and a structural layer associated with the venting layer. The venting layer has a venting layer O2 passage rate and a venting layer surface area, while the structural layer has a structural layer O2 passage rate and a structural layer surface area. The venting layer O2 passage rate is greater than the structural layer O2 passage rate, and the structural layer surface area is less than the venting layer surface area. Alternatively, the structural layer may include a plurality of apertures and a patch associated with each aperture, instead of a venting layer. Each patch has a patch O2 passage rate and the total O2 passage rate of the container includes the sum of each patch O2 passage rate. The total O2 passage rate is at least about 0.2 L/(m2*24 hours).

Abstract: A refilling system for reducing messiness during use includes a container and a refilling container. The container includes a hollow bottle, a pouring spout, and a cap which covers the pouring spout. The pouring spout has an interior surface. The refilling container includes a hollow body a refilling spout and contains a composition therein. The refilling spout has an exterior surface. In the refilling system, the interior surface and the exterior surface are coordinated such that the exterior surface may fit within the interior surface during use.
