Chemical reaction cartridge and method of using same

Abstract

A chemical reaction cartridge enabling chemical reaction to be stably and safely carried out therein, and a method of using the same are provided. A chemical reaction cartridge is provided with a substrate, and an elastic member 2 overlaid on the substrate. A recess of a predetermined shape, depressed toward the top surface of the elastic member is formed in the back surface of the elastic member. The recess creates space between the substrate, and the elastic member, thereby making up a well, for holding the main ingredient of the epoxy adhesive, a flow path communicating with the well, a well for holding a curing agent for the epoxy adhesive, a flow path communicating with the well, a mixing part for mixing the main ingredient with the curing agent, and a discharge path for discharging a mixture. While the chemical reaction cartridge is not in use as yet, the flow paths, and the discharge path are closed, so that the wells are, in effect, in a hermetically sealed condition. The mixing part is made up of a plurality of flow paths intersecting each other. The respective starting ends of the flow paths are each linked with the flow path, or the flow path, and the respective terminals of the flow paths are linked with the discharge path. The terminal of the discharge path communicates with the outside via an end face of the cartridge.

1 . A chemical reaction cartridge capable of causing deformation to occur thereto upon application of an external force thereto, and transferring substances contained therein to thereby apply a chemical reaction, said cartridge comprising:
 a plurality of substance holding wells which are distributed along a length direction of the cartridge, and   a substance receiving well connected to each of said plurality of substance holding wells and disposed at a different position along the length direction of the cartridge as said plurality of substance holding wells,   wherein distances in the length direction between each of said plurality of substance holding wells and said substance receiving well are different, and   wherein upon application of the external force the substance is transferred from at least one of said plurality of identical substance wells to said substance receiving well.   
     
     
         2 . A method of adjusting the quantity of a substance to be transferred by a roller, comprising:
 providing a cartridge having a plurality of substance holding wells which are distributed along a length direction of the cartridge, and a substance receiving well connected to each of said plurality of substance holding wells and disposed at a different position along the length direction of the cartridge as said plurality of substance holding wells, such that distances in the length direction between each of said plurality of substance holding wells and said substance receiving well are different, and   positioning the roller prior to rolling at a position corresponding to a quantity of the substance to be transferred, and   rolling the roller in order to transfer the quantity of the substance to said substance receiving well,   wherein when a greater quantity of the substance is to be transferred, the roller is positioned with a greater number of said plurality of substance holding wells between said roller and said substance receiving well than when a lesser quantity of the substance is to be transferred.   
     
     
         3 . A method of adjusting the kind or quantity of a substance to be transferred by a roller, comprising:
 providing a cartridge having a plurality of substance holding wells which are distributed at different positions in a width direction of the cartridge, and a substance receiving well connected to each of said plurality of substance holding wells, and   positioning the roller prior to rolling at a position corresponding to one or more of said plurality of substance holding wells which contain the substance to be transferred, and   rolling the roller in order to transfer the substance to said substance receiving well,   wherein the roller is positionable in the width direction at a position corresponding to a first one of said plurality of substance holding wells but not a second one of said plurality of substance holding wells, or is positionable in the width direction at a position corresponding to the second one of said plurality of substance holding wells but not the first one of said plurality of substance holding wells.
