Abstract
An ink container includes a housing, a print head, and a fluid chamber. The housing has two inclined walls formed to divide the fluid chamber into a center ink well and two side ink wells. The housing also has two side walls, each having an inclined inner surface. The center ink well is formed between the two inclined walls. Each side ink well is formed between an inclined wall and a side wall. The inner surface of each side wall has a greater inclination than those of the inclined walls, so that each side ink well has a width decreasing from top to bottom.
Claims8
A fluid container comprising:
- a housing having two side walls each having an inner surface;
- a print head installed at bottom of the housing for injecting fluid onto a document;
- and
- a fluid chamber formed inside the housing having two inclined walls for dividing the fluid chamber into a center fluid well and two side fluid wells, the center fluid well being formed between the two inclined walls and having a width decreasing from top to bottom, the two side fluid wells each formed between an inclined wall and a corresponding side wall;
- wherein the inner surface of at least one of the side walls has a greater inclination than that of the corresponding inclined wall so that the side fluid well formed between the side wall and the inclined wall has a width decreasing from top.
