A box for conveniently storing and dispensing pourable materials has a front wall having a first and a second opening and an inside surface. The base has a recess defined in the base. The gas supply device is developed in such a way that the first temperature T1 is higher than the second temperature T2. A child-resistant locking ring is received by the container holder and cooperates with the dispensing tip for alternately configuring the product-dispensing apparatus in either a locked or unlocked condition. are input through first input-output port of first optical multiplexerdemultiplexer circuit, multiplex signals of odd wavelength \u03bb1, \u03bb3, \u03bb5. An Intensity Based Colormap may be used to convert Computer Input image data using a Computer Machine encoded with an Intensity Based Colormap.
