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.

The present disclosure relates to a discharging apparatus and a 3D printing device thereof, which pertains to the field of the 3D printing device. The discharging apparatus includes a housing, a driving module, and a heating module. The housing includes a body portion, and a movable portion detachably or rotatably connected to the body portion, wherein one end of the body portion is provided with a discharging hole, and in an operating state, the body portion and the movable portion form a relatively enclosed accommodating space. One end of the driving module is connected to the body portion, and the other end of the driving module is movable by a predetermined distance in the accommodating space. The heating module is attached to an inner wall of the body portion and/or the movable portion. In the present disclosure, the heating module is configured to adjust a heating temperature for heating according to a property of a printing material/or a discharging parameter, such that the heating temperature of the heating module is adjusted according to a food material with different molten properties, and 3D printing is practiced using different printing materials. In this way, the problem that an existing chocolate 3D printer can only use chocolate with single purity for the 3D printing and adaptability is poor is solved.

Content containers and vessels, one aspect including a chocolate dispensing vessel, having a generally fluid-tight enclosure, chocolate substantially filling the fluid-tight enclosure, a fluidic conduit extending through the fluid-tight enclosure, and a fluidic valve operationally connected to the fluidic conduit and positioned outside of the fluid-tight enclosure. The chocolate is solid state at room temperature and the chocolate softens to a liquid state in the temperature range from 26 to 36 degrees Celsius.
