  • Patent number: 10759179
    Abstract: Provided is a technique that can reduce at least one of various inconveniences in a sub-tank, such as stock management being complicated. The sub-tank includes: a consumable article containing portion; a sub-tank-side storage unit; and a case that can be detachably attached to multiple slots in a consumable article consumption apparatus and contains the consumable article containing portion.
