Abstract: Provided is a technique of disassembling an ink pack into a single material and improving the recyclability. That is, the technique may contribute to realization of a sustainable society such as a decarbonized/recycling society. To this end, an ink container configured to contain an ink includes: a first container configured to contain the ink; and an ink supply unit joined to the first container and configured to supply the ink in the first container to outside of the ink container, in which the first container and the ink supply unit are adhered to each other via an adhesive in each adhesion region.

Abstract: A liquid container being able to be detachably attached to a liquid ejecting device and supplying a liquid to the liquid ejecting device is provided, the liquid container including: a bag member having an accommodating portion, which accommodates the liquid inside and has flexibility, and a supply port which supplies the liquid in the accommodating portion to the liquid ejecting device; and a positioning member fixed to the bag member and positioned with respect to the liquid ejecting device, wherein the bag member further has a handle portion.

Abstract: In a method for manufacturing a liquid ejection head having an ejection unit including an element substrate provided with ejection ports to eject liquid, and a support member to support the ejection unit with a support surface and provided with a liquid supply path, the method includes arranging and curing. A first adhesive is arranged to surround the supply path and a second adhesive is arranged in each of at least three of four areas obtained by dividing an area where the ejection unit contacts the support surface by a first straight line connecting centers of two sides and a second straight line connecting centers of two sides at a position overlapping an outer periphery of the area where the ejection unit contacts the support surface. The ejection unit is arranged on the support surface, the second adhesive is cured, and the first adhesive is cured in this order.
