Content containers and vessels, one aspect including a deformable fluid-tight container shell defining an internal volume and separating the internal volume from an external environment a room-temperature semi-solid content contained within the internal volume and a valve operationally connected to and disposed at least partially without the deformable container shell where the semi-solid content is a hydrophobic matrix with at least partially emulsified hydrophilic components where the container shell is substantially fluid-tight where the valve has open state(s) and a closed state where the valve may be actuated between the open state(s) and the closed state where the valve is self-cleaning where during the open state(s), the internal volume is in fluidic communication with the external environment where during the closed state, the internal volume content cannot fluidically communicate with the external environment and where the content remains moisture-stable while the valve is in the closed state.
