As a result, the contents M poured out from the mouth 2b of the container body 2 and accumulated in the large-diameter cylindrical portion 12 flow into the dispensing cylindrical portion 13 through the notch window portion 21a, and are poured from the dispensing outlet 13a. The container body 31 of the continuous use container 30 is filled through the exit guide portion 44. In addition, since the stopper piece 23 has the axial direction extension part 23b, the clearance gap is provided between the bottom part 22 and the stopper wall 12a of the stopper 20, and the content M poured out from the opening part 2b. Can flow through the gap to the notch window portion 21a.

  In such a configuration, the total area of the pair of cutout window portions 21a provided in the inner cylinder portion 21 of the plug body 20 is tested in advance so that refilling is performed at an appropriate flow rate according to the viscosity of the contents M. The content M can be made to flow at an appropriate flow rate from the dispensing cylinder portion 13 toward the dispensing guide portion 44. Accordingly, since the contents M can be poured out from the dispensing cylinder 13 toward the dispensing guide 44 at an appropriate flow rate during the refilling operation, the contents M to be refilled are received by the receiving member 40 of the continuous use container 30. The slit 44a and the air replacement opening 45 are closed, thereby preventing the contents M from spilling out of the receiving member 40 to the outside. Moreover, the refill container which does not produce a leak with respect to the content M which has various viscosity by using the stopper 20 provided with the notch window part 21a of the appropriate area according to the viscosity of the content M is provided. 1 can be manufactured.

  With such a configuration, the refill container 1 is placed in an inverted posture, and the spout 13a of the pour cylinder portion 13 is engaged with the tip of the pour guide portion 44 of the continuously used container 30 in the standing posture and is only pushed downward. The contents M can be easily refilled from the refilling container 1 into the continuous use container 30 by the simple operation.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, in the above-described embodiment, the extraction cylinder part and the large diameter cylinder part are formed in a cylindrical shape, but the present invention is not limited thereto, and the extraction cylinder part and the large diameter cylinder part have, for example, a rectangular cross section. It can also be formed into a cylindrical shape having another cross-sectional shape such as a cylindrical shape.

  Moreover, in the said embodiment, although the extraction | injection cylinder part 13 is formed separately from the large diameter cylinder part 12, it is set as the structure fixed by fitting to the large diameter cylinder part 12, If it is the structure which can arrange | position the plug body 20 inside, it can also be set as the structure which forms the extraction cylinder part 13 integrally with the large diameter cylinder part 12. FIG.

  Furthermore, other containers in which the contents M can be refilled from the refill container 1 are not limited to the continuous use container 30 as described above, but include a receiving member 40 having a structure that can be engaged with the dispensing cylinder portion 13. If it exists, it may be a container having another structure.
