Abstract
A liquid storage includes at least three layers, an inner layer made of paper base material and an intermediate layer of a paper base laminate having a metal layer or a silica vapor deposition layer formed on the outer surface side of the paper-based inner layer, and an outer layer made of paper base material formed on the outer surface side of the intermediate layer. The paper base laminate is wound into a spiral shape and on the outer surface side of the intermediate layer, the outer layer is also wound into a spiral shape. A polyolefin resin-containing adhesive layer lies in between the inner and intermediate layers and/or between the intermediate and outer layers.
Claims14
A liquid storage member for coating tools having at least three layers of:
