  The discharge port provided in the top plate member is sealed by a seal member mainly made of a laminated film having gas barrier properties in order to prevent solidification, drying prevention, and quality maintenance of the flowable substance until the start of discharge.

  In the techniques of Patent Documents 1 to 4, the seal member is attached to the inner surface of the top plate member that is inside the cartridge, and the base end of the nozzle that is fitted into and attached to the discharge port of the top plate member at the start of discharge. The seal member is pierced by the piercing portion so that the inside of the cylindrical housing cylinder communicates with the nozzle.

  When the seal member is pierced by the pierced portion of the nozzle, the seal member is not sufficiently adhered to the top plate member, or depending on various conditions such as the elasticity of the seal member, peeling in the piercing direction side -It has been found that there is a case where stretching or the like occurs and penetration due to the breakage of the seal member becomes difficult, resulting in a problem in dischargeability.

  In addition, in order to ensure the breakage of the seal member, a configuration in which the nozzle piercing portion is set to be long is conceivable, but according to such a configuration, the piercing portion from the back surface side of the top plate member to the inside of the cylindrical housing cylinder Since the protrusion of the tube becomes large, the bottom member moving by the plunger push-out interferes with this protruding piercing part, making it impossible to crush the cylindrical storage cylinder to the end, and the fluid substance cannot be used up. It will have the problem of remaining.

  In the techniques of Patent Documents 1 to 3, since the seal member is for sealing the discharge port, the seal member covers only the discharge port and the periphery of the discharge port. It has also been found that the gas barrier property cannot be maintained at the plate member portion, which is insufficient in terms of preventing the change of the flowable substance.

  In this regard, in the technique of Patent Document 4, the sealing member is not only the discharge port and the periphery of the discharge port, but also the entire inner surface of the top plate member, as well as a reinforcing ring member attached to the tip of the cylindrical housing cylinder, It is the structure which the said sealing member coat | covers even the insertion joining part.

  However, according to the configuration of Patent Document 4, when the top plate member is fitted and joined to the ring member, the seal member located on the fitting sliding surface is broken or damaged by a load such as fitting pressure, It has been found that gaps are generated due to the generation of soot, etc., and not only the gas barrier property, gas tightness, liquid tightness and moisture resistance are lowered, but also liquid leakage may occur depending on the degree.

  Therefore, the object of the present invention is to ensure good gas barrier properties, gas tightness, liquid tightness, moisture resistance, good discharge properties, and to use as much of the filled fluid substance as possible. The object is to provide a cartridge for a flowable substance.

  The present invention for solving the above problems has the following configuration.
