A pair of large-diameter portions 23b are provided at opposite positions, and a climbing rib 23c is provided on the LOCK position side of the large-diameter portion 23b ( (See FIG. 3). An outer container side locking recess 24 is provided on the entire inner periphery of the upper inner surface of the outer peripheral wall 21.

  The inner container 3 is provided with an outer flange-shaped flange part 32 via an inner peripheral wall part 31, and the flange part 32 is placed on the outer peripheral wall upper end part 21 a of the outer container 2 (see FIG. 1). A support piece 33 is suspended from the flange portion 32, and an inner container side locking convex portion 33 a that is locked to the outer container side locking concave portion 24 protrudes from the entire outer peripheral surface of the support piece 33. A male screw portion 34 is engraved on the upper outer peripheral surface of the inner peripheral wall portion 31. On the inner surface of the lower part of the inner peripheral wall portion 31, a pair of inner container recess portions 35 in which the inner peripheral wall portion 31 is thin are provided at positions that face symmetrically. The inner container recess 35 may have any size and shape that allows a part of a locking member 55 described later to enter. And the inner container bottom wall 36 is provided in the center part of the lower inner surface of the inner peripheral wall part 31 except the inner container hollow part 35 vicinity.

  The refill container 4 has a substantially cylindrical refill peripheral wall portion 41 and a refill bottom portion 42 provided below the refill peripheral wall portion 41, and a refill flange portion having an outer casing shape from the upper end portion of the refill peripheral wall portion 41. 43 is provided (see FIG. 1). A connecting piece 44 is suspended from the outer surface of the refill bottom portion 42 over the entire circumference, and a projecting portion 44 a projects from the entire lower outer periphery of the connecting piece 44.

  In the lock dial 5, a substantially circular bottom plate portion 51 that fits in the bottom portion opening 23, and a lock dial peripheral wall portion 51 a are provided upright and continuously from the end edge of the bottom plate portion 51 via a stepped portion. A knob 52 for hanging a fingertip when the lock dial 5 is rotated downward from the bottom plate 51 is provided in a hanging manner. The knob portion 52 extends linearly in the diameter direction of the bottom plate portion 51, the tip portion 52 a slightly protrudes from the bottom plate portion 51, and the length between the tip portions 52 a and 52 a at both ends is small. Since it is longer than the diameter of the portion 23a and slightly shorter than the diameter of the large diameter portion 23b of the bottom opening 23, the tip portion 52a slides on the large diameter portion 23b. An arm portion 53 is extended from the outer periphery of the lock dial peripheral wall portion 51a via an inner hinge portion 54a, and a locking member 55 is integrally connected to an outer end portion of the arm portion 53 via an outer hinge portion 54b. . On the upper portion of the locking member 55, a locking means 55a that fits with the protruding portion 44a is projected. The locking member 55 is a curved plate-like member, and by making the curvature radius of the curve constituting the locking member 55 equal or close to the curvature radius of the connecting piece 44 of the refill container 4, the locking means 55a and the protrusion The part 44a can be fitted more firmly. Note that the lock dial 5 is not limited to being integrally connected. For example, the lock dial 5 has a structure in which the arm portion 53 and the locking member 55 are formed separately and connected via the hinge portion 54. It doesn't matter. Further, the lock dial peripheral wall portion 51a may not be provided. For example, the bottom plate portion 51 may be a substantially circular member, and the arm portion 53 may be extended from the outer periphery of the bottom plate portion 51 via the inner hinge portion 54a.

  When no force is applied to the lock dial 5 and no load is applied and the knob 52 is in the OPEN position, as shown in FIG. 5, the hinge portion 54 is not bent, so the arm portion 53 is separated from the lock dial peripheral wall portion 51a. By extending linearly, the locking member 55 is pushed outward and enters the inner container recess 35. In a state where the hinge portion 54 is not bent, the inner hinge portion 54a, the arm portion 53, the outer hinge portion 54b, and the locking member 55 are provided at positions facing each other with the bottom plate portion 51 interposed therebetween. On the other hand, as shown in FIG. 2, when the knob 52 is rotated counterclockwise, the hinge 54 is bent so that the locking member 55 is pulled inward.

  The cap 6 is a top tube-like overcap body that is screw-fitted to the male thread portion 34 of the inner container 3, and has a disk-shaped top wall portion 61 and a cylindrical shape that is suspended from the edge of the top wall portion 61. Peripheral wall 62 (see FIG. 1). On the inner peripheral surface of the peripheral wall portion 62, a female screw portion 63 that is screwed into the male screw portion 34 is formed. A disc-shaped packing 7 is fitted inside the cap 6. The packing 7 is joined to the lower surface of the top wall portion 61 of the cap 6, and the outer peripheral portion of the packing 7 is sandwiched between the lower surface of the top wall portion 61 and the upper surface of the refill flange portion 43 and sealed. The replacement container 1 is sealed.

Next, the operation of the replacement container 1 configured as described above will be described.
When the contents in the refill container 4 accommodated in the inner container 3 run out, when replacing the refill container 4 with a new one, the cap 6 attached to the inner container 3 shown in FIG. Remove. When the cap 6 is removed, the packing 7 is also removed.

  In this state, the refill container 4 is housed in the inner container 3, and the tip 52a of the knob 52 is locked by the climbing rib 23c, so that the lock dial 5 is in the locked state shown in FIGS. It has become. In this locked state, the inner hinge portion 54a and the outer hinge portion 54b are bent, whereby the locking member 55 is drawn inward, and the locking means 55a is fitted into the protruding portion 44a in an undercut shape. The refill container 4 is fixed to the inner container 3 (see FIG. 1).

  Next, in order to remove the refill container 4 from the inner container 3, when the knob 52 is picked with the fingertip and the lock dial 5 is rotated, the tip 52a gets over the LOCK position side overpass rib 23c, and the large diameter part 23b is removed. Slide toward the OPEN position (see FIG. 6). By turning the lock dial 5, as shown in FIG. 5, the bending of the hinge portion 54 is eliminated, and the arm portion 53 moves the locking member 55 outward, and a part of the locking member 55 is in the inner container. It enters into the recess 35. Due to the outward movement of the locking member 55, the engagement between the locking means 55a and the protrusion 44a is released (see FIG. 4).

  When the engagement between the locking means 55a and the projection 44a is released, the refill container 4 can be freely pulled out, and the refill flange 43 and the like are picked up with a fingertip and pulled upward as shown in FIG. 3, the refill container 4 is removed. Thereafter, a new refill container 4 is inserted into the inner container 3, the lock dial 5 is rotated, and when the distal end 52a rides over the overpass rib 23c on the LOCK position side and the lock dial 5 is brought into the locked state, the hinge portion When the locking member 55 is bent, the locking member 55 is pulled inward, the locking means 55 a and the projection 44 a are fitted, and the refill container 4 is fixed to the inner container 3.

  As described above, in the present invention, since the refill container 4 is firmly fitted by the locking means 55a and the protrusion 44a at the time of locking, the refill container 4 is forcibly pulled out or the replacement container 1 is accidentally dropped. It is possible to prevent the refill container 4 from coming off due to an impact or the like.
