Abstract
A tank unit includes two or more liquid accommodating containers disposed in a row. Each of the liquid accommodating containers includes a main body having a concave shape defining a side opening and a film that blocks the side opening. The main body and the film at least partially define a liquid accommodating chamber for accommodating a liquid. The main body includes a facing wall that faces the film across the liquid accommodating chamber and has a wall larger than the side opening. The liquid accommodating containers are disposed such that the film of at least one of the liquid accommodating containers is covered by the facing wall of an adjacent one of the liquid accommodating containers.
Claims20
A tank unit for supplying liquid from outside of a liquid ejecting apparatus to the liquid ejecting apparatus, the tank unit comprising:
- a plurality of liquid accommodating containers disposed in a row, each of the liquid accommodating containers including a main body having a concave shape defining a side opening and a film that blocks the side opening, the main body and the film at least partially defining a liquid accommodating chamber for accommodating a liquid, the main body including a facing wall that faces the film across the liquid accommodating chamber, the facing wall having a wall larger than the side opening, the liquid accommodating containers being disposed such that the film of at least one of the liquid accommodating containers is covered by the facing wall of an adjacent one of the liquid accommodating containers.
A method of making a tank unit for supplying liquid to a liquid ejecting apparatus, the method comprising:
- providing a first main body having a first concave shape defining a first side opening, the first concave shape being partially defined by a first facing wall portion of the first main body;
- attaching a first film to the first main body to block the first side opening so that the combination of the first main body and the first film at least partially defines a first liquid chamber for accommodating a first liquid, the first facing wall portion facing the first film across the first liquid chamber;
- providing a second main body having a second concave shape defining a second side opening, the second concave shape being partially defined by a second facing wall portion of the second main body;
- attaching a second film to the second main body to block the second side opening so that the combination of the second main body and the second film at least partially defines a second liquid chamber for accommodating a second liquid, the second facing wall portion facing the second film across the second liquid chamber;
- and
- coupling the second main body with the first main body so that the second facing wall portion covers the first film.
