  Since the container of patent document 2 forms the communicating path with a shielding valve under the upper half part of the rotating cylinder which fitted the lower part of the pump cylinder, the storage space of a bag body is only the width of the upper and lower sides of the communicating path. In addition to being restricted, the flow path area is also narrowed, and it is difficult to suck all the liquid in the upper corner of the bag body.

  It is an object of the present invention to provide a dispenser storage bag with a mouth member that can be easily and inexpensively manufactured while eliminating these drawbacks of the prior art and is easy to use, and a refillable pump container using the bag. Objective.

This engaging groove is inclined slightly upward from the upper end of the vertical strip portion 77a, and the horizontal strip portion 77b extends over about 1/4 of the connecting cylinder. According to this structure, the upper end portion of the mouth member 6 can be brought into pressure contact with the flange 50 side of the cylinder body 46 by the engagement convex portion 10 sliding obliquely upward in the horizontal strip portion 77b. Moreover, the movement of the engaging convex part 10 between a vertical strip part and a horizontal strip part becomes smooth. Further, in the illustrated example, the upper half of the vertical stripe portion 77a and the horizontal stripe portion 77b of the engagement concave ridge 77 are divided so as to come out of the connecting cylinder 68, and the engagement convex portion 1 is The lower half of the vertical strip 77a is forcibly moved over and snap-fitted to the upper half of the vertical strip 77a.

  Further, the rotary cylinder 16 hangs from the bottom wall 18 a flow path forming portion 110 formed by connecting two vertical plates in a cross shape when viewed from below. In the illustrated example, each vertical plate 112 is tapered downward.

    Further, a vertical rib-like engagement strip 28 is provided at a suitable place on the upper outer surface of the rotary cylinder 16 (above the communication hole 20 in the illustrated example).

  Further, as shown in FIGS. 14 and 16, the mounting cylinder 8 is provided with a constricted portion 116 for preventing sink marks at an intermediate portion in the vertical direction in the axial direction of the tubular wall, and is positioned slightly above the constricted portion. Thus, a pair of engaging projections 10 project outward from both sides of the cylinder wall of the mounting cylinder. As shown in FIG. 15, shallow groove-like engagement strips 70 are vertically provided on the inner surface of the upper half cylinder portion of the mounting cylinder 8. The width of the engagement strip 70 corresponds to the circumferential length of the communication groove 12 and the communication hole 20 in the shipping state shown in FIG. 1 of the bag body 2. This corresponds to / 4 lap.

  In the illustrated example, the covering cylinder 106 is formed of a bottomed cylinder main body 106a and an auxiliary cylinder portion 106b fitted to the upper inner surface of the cylinder main body.
