Patent ID: 8486347

Claim:
A carrier-enclosed transformable container having: containing part which can contain liquid and gas at its inside surrounded by a wall face, a part of this wall face having a transformable wall face capable of undergoing a predetermined transformation without changing the entire internal surface area of the wall face substantially; an orifice part which is connected to the containing part at an end thereof opposite the transformable wall face and which can undergo the inflow and outflow of a fluid sucked and discharged by the expansion and contraction of the inside by the transformation of the transformable wall face, respectively; a carrier to which a predetermined substance enclosed in the containing part to be in a substantially stationary state is bonded or bondable, and an enclosing portion for enclosing the carrier into the containing part in the state that the carrier can contact a fluid flowing from the orifice part to the containing part; wherein positions where the substance is bonded or bondable are caused to correspond to predetermined positions of an individual of the carrier at intervals, or to correspond to plural individuals of the carrier, and about the carrier, its positions to which the predetermined substance is bonded or bondable can be specified from the outside, wherein the containing part has one or more transformable portions formed by the transformable wall face, and a non-transformable portion connected to the transformable portion(s), and surrounded by a non-transformable wall face, which is not transformable, and is also connected to the orifice part, the inside of the non-transformable portion being permitted to be measured from the outside, and wherein the enclosing portion is part of the non-transformable portion and thus the carrier is enclosed in the non-transformable portion; wherein the orifice part has a size that permits the carrier to pass through the orifice part in a direction that corresponds to a flow direction in which the fluid is sucked into the opening part and flows through the opening and the enclosing portion; and wherein either: the enclosing portion has a carrier-passage-blocking member arranged so that the fluid can pass out of the enclosing portion in the flow direction but the carrier cannot pass out of the enclosing portion in the flow direction, the carrier-passage-blocking member being positioned to separate the carrier from the transformable portion(s) along the flow direction, or the containing part has a projected region formed by the non-transformable wall face projecting in a direction perpendicular to the flow direction so that the fluid can pass out of the enclosing portion in the flow direction but the carrier cannot pass out of the enclosing portion in the flow direction, the projected region being positioned to separate the carrier from the transformable portion(s) along the flow direction.
