Abstract

There exists a need for an ink container for Thermal Ink Jet (TIJ) processes having the following properties: low cost; disposable; no mess to handle when loading and unloading; large volume capacity, ca. one half liter; and a simple detecting means when the container is approaching empty. A novel TIJ ink container that accomplishes the desired needs may be realized when based upon a "winebox" design concept. That is, a mylar envelope or bag liner contains the liquid ink and a cardboard or similarly constructed box serves as the outer container for the bag as shown in Figure 1. The designs affords a number of advantages including: protecting the ink formulation from exposure to air thereby preventing oxidative deterioration or evaporation of the ink formulation; simple and economical packaging and transportation; readily disposable; and the collapsible container bag indicates a 'low ink' condition. In combination with the ink container reservoir is a connection valve device, Figure 2. In one embodiment as shown in the figure, the valve acts as a simple rotary cut-off valve which operates automatically when engaged with a fixed profiled track. Placing the ink container in the fixed receptacle during connection provides the necessary motion to open the valve. Upon removal of a low or empty container the spigot closes and prevents leaks.
