  The connecting cylinder member C has an outer periphery of the main cylinder 6 that rises upward by fitting the mounting cylinder 5 to the outer periphery of the mouth-and-neck part 2 and fitting the lower end part liquid-tightly to the inner periphery of the mouth-and-neck part 2. A thread 7 is provided around the inner periphery, and a first tooth group a constituting a ratchet mechanism is supported at the lower part of the inner periphery thereof.

  In the illustrated example, a mounting cylinder 5 having a thread 8 threadedly engaged with a thread 3 on the outer periphery of the mouth-and-neck part 2 is screwed to the outer periphery of the mouth-neck part 2, and the lower part of the mounting cylinder 5 is broken. A separation band 5a is defined by surrounding the portion 9, and a plurality of circumferentially projecting engagement protrusions 10 on the lower end of the inner periphery of the separation band 5a are formed on the lower surface of the locking protrusion 4 It is engaged by getting over and preventing it from coming out. The breaking portion 9 only needs to have a connection strength that can separate the separation band 5a locked by the pull-out prevention means when the mounting cylinder 5 is to be screwed off. In the illustrated example, the separation band 5a is provided. And other mounting cylinders 5 are connected by thin rod-like connecting pieces 11 at a plurality of positions in the circumferential direction. In addition, a trapezoidal shape having a vertical edge corresponding to the vertical edge of the inverted trapezoidal protrusion 12 from the upper surface of the separation band 5a is provided by suspending an inverted trapezoidal protrusion 12 having a predetermined side as a vertical edge from the lower surface of the mounting cylinder 5. The protrusion 13 is erected adjacently. Due to the presence of these protrusions, the load is not easily applied to each connecting piece 11 when rotating in the screwing direction, and the load is applied to each connecting piece 11 when rotating in the screwing direction.

  Further, the main cylinder 6 is erected upward with a lower part closely fitted to the inner periphery of the mouth neck 2 through a flange 14 extending inwardly from the upper end edge of the mounting cylinder 5. The screw 7 is provided around the outer periphery of the main cylinder 6, and a locking protrusion 15 is provided around the lower portion of the main cylinder 6 in the same manner as the mouth-and-neck portion 2. A plurality of connecting plates 16 in the circumferential direction protrude from the lower end of the inner surface of the main tube 6, the fixed tube 17 is supported in a double cylinder shape via each connecting plate 16, and the first tooth group a is provided on the inner surface thereof. Forming. A large number of unit teeth 18 constituting the first tooth group a are all inclined at the same inclination in the same predetermined direction.

The second container B is screwed with the upper end of the mouth-neck portion closed. In the illustrated example, a mounting cylinder 20 having a thread 19 that is screwed with a thread 7 on the outer periphery of the main cylinder 6 is screwed to the inner surface, and a fracture portion 21 is provided around the lower part of the mounting cylinder 20. Thus, the separation band 20a is defined. Similarly, the engagement protrusion 22 is moved over and engaged with the lower surface of the locking protrusion 15 to prevent the separation. Further, a bottomed cylindrical main body 24 defining a second storage chamber R ₂ for storing a second storage item is suspended from the back surface of the top wall 23 extending from the upper end edge of the mounting cylinder 20. ing. The top wall 23 is configured as a separate body, and the peripheral edge thereof is hermetically fixed by fixing means such as fitting and fusion. Further, the main body portion 24 is provided upright rod-shaped projection 25 for stirring the stored items upon opening, the rod-shaped by the presence of the projections 25 of the second in housing chamber R ₂ stored item is first stored to fall When mixing with the stored items in the room, the two are mixed more rapidly by stirring. It should be noted that the intended purpose can be achieved without providing the rod-like projections as shown in the example of FIG.

  The second container B is provided with an annular thin broken line 26. The thin broken line 26 is configured to be broken when the second container B is screwed, and the stored item in the second container B falls into the first container A. The thin break line 26 is provided around the peripheral edge of the bottom wall 24a of the main body 24. However, the present invention is not limited to this, and may be any position where the stored item in the second container B can be dropped when it is broken. .

  Further, a second tooth group b that meshes with the first tooth group a is provided on the outer surface of the working cylinder 27 that is suspended from the back surface of the inner body bottom wall 24a inside the thin broken line 26, Thus, the ratchet mechanism in which the second container B is already turned in the screwing direction is configured. Similarly, the unit teeth 18 constituting the second tooth group b are also inclined in the predetermined direction with the same inclination. When the second container B is screwed, the second tooth group b can move over the first tooth group a and can be screwed. When the second container B is screwed, the second tooth group b can be screwed. The tooth group b is configured to be unable to rotate with respect to each other by the action of a ratchet mechanism that engages the first tooth group a.

An in-mold label 28 is attached to the outer surface of the second container B. The in-mold label is formed by a known method such as in-mold coating, has a gas barrier property, and is fixed in a state of substantially covering the upper surface, the peripheral surface, and the lower surface of the main body .

  The two-type mixing container configured as described above stores, for example, liquid and solid storage items in the first container A and the second container B, respectively, and is used by mixing them in use. In use, when the mounting cylinder 20 of the second container B is rotated in the screwing direction from the state shown in FIG. 1, the breaking portion 21 is broken and screwed up. At this time, the main body 24 and the operating cylinder 27 are also about to rotate in the screwing direction, but the result is that the ratchet mechanism is activated and the operating cylinder 27 does not rotate but only the main body 24 is about to rotate. Then, a shearing force acts on the thin break line 26 and breaks, and as shown in FIG. 3, the stored item in the second storage chamber of the second container B falls into the first storage chamber of the first container A, Mix with the contents. At this time, the separated bottom wall 24a and rod-like protrusion 25 are locked to the fixed cylinder 17 to maintain the state as it is, but may be configured to fall into the first container A.

  Next, if necessary, after the mixture is stirred, when the mounting cylinder 5 of the cylinder member C is rotated in the screwing direction, the fracture portion 9 is broken, and the second container B and the cylinder member C are broken as shown in FIG. Can be removed from the first container A, and the mixed storage can be taken out.
