Material dispensing device

A material dispensing device, comprising:

• a first flexible hollow housing, made of an ela5torner, the housing having a first end and a second end and being an outermost, integral surface of the material dispensing device;
• and
• a removable cap, base, or connector configured to be separably connected to the first end of the first flexible hollow housing, thus defining a first compartment configured to enclose foodstuff or non-foodstuff materials in solid, granular, powder, semi-liquid, or liquid forms,
• wherein the first flexible hollow housing extends from the removable cap, base, or connector to the second end at a terminus of the material dispensing device, the terminus being opposite the first end,
• wherein the first flexible hollow housing comprises integral external ribs, a first slit, and a second slit at the second end,
• wherein the first flexible hollow housing is configured to be in a closed state and to open when a user applies a manual lateral force to external surfaces of the first flexible hollow housing in proximity to the second end, thus allowing enclosed materials in the first flexible hollow housing to pass through the slits out of the first compartment,
• wherein the second end comprises a first plurality of the external ribs, integral with the first flexible hollow housing, configured to force the slit to maintain the closed state when no lateral force is applied to external surfaces of the first flexible hollow housing,
• wherein the slits and the first end each form a cross shape and are collinear with a first central axis line of the first flexible hollow housing,
• wherein the first plurality of external ribs extend to the second end parallel to the first central axis line,
• wherein the second end is planar or concave seen along the first central axis line from the second end toward the first end, and
• wherein the first end comprises a first plurality of internal ribs distributed within an inner surface of the first flexible housing, extending towards the second end from a first lip at the first end in a direction of the first central axis line.
