  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of the two-type mixing container 1 of the present invention. The container 1 includes a first container A and a second container B.

In the first container A, the mouth and neck portion 3 is erected from the trunk portion 2, and a locking protrusion 4 is provided on the outer periphery of the mouth and neck portion 3. The inside of the body portion 2 is configured as a first storage chamber R ₁ for storing a solid storage item such as a liquid to be mixed, powder, or granule.

  The second container B is formed by closing the upper end opening of the mouth-and-neck part 3 and screwing it. In the illustrated example, the second container B is attached to the first container A via a cylindrical member C. The cylindrical member C is fitted with the mounting cylinder 5 on the outer periphery of the mouth-and-neck portion 3, the screw-tube 6 is erected above the mouth-and-neck portion 3, and the engaging portion 7 is vertically suspended in the mouth-and-neck portion 3. ing. When the second container B is screwed off, the engaging portion 7 is for contacting an annular surface 24, which will be described later, to break a thin breaking line, which will be described later. Even if it exists, it can select variously.

  In the illustrated example, a mounting cylinder 5 having an engaging ridge 8 protruding over and engaged with a locking ridge 4 on the outer periphery of the mouth and neck portion 3 is fitted on the outer periphery of the mouth and neck portion 3. Further, the engaging portion 7 is suspended downward from the inner peripheral edge of the flange 9 extending inward from the upper end edge of the mounting cylinder 5, and the screw cylinder 6 is erected upward from the upper surface of the flange 9. A screw thread 10 is provided around the outer periphery of the screw tube 6, and a locking protrusion 11 is provided below the screw thread 10. Further, the engaging portion 7 has a plurality of engaging protrusions 7b whose lower ends are curved toward the center side on the bottom surface of a cylindrical mounting base 7a fitted from the inner peripheral edge of the flange 9 to the back surface of the mouth neck portion 3. It is provided and configured.

  The second container B is screwed with the upper end of the mouth-neck portion closed. In the illustrated example, a mounting cylinder 13 having a thread 12 threadedly engaged with a thread 10 on the outer periphery of the screw cylinder 6 is screwed on the inner surface, and a breaking portion 14 is provided around the lower part of the mounting cylinder 13. Thus, the separation band 13a is defined, and the engagement protrusion 15 provided on the inner surface of the separation band 13a is engaged with the lower surface of the locking protrusion 11 to prevent the separation band 13a from coming out. The breaking portion 14 only needs to have a connection strength that can separate the separation band 13a locked by the pull-out prevention means when the mounting cylinder 13 is to be screwed off. In the illustrated example, the separation band 13a And other mounting cylinders 13 are connected by thin rod-like connecting pieces 16 at a plurality of positions in the circumferential direction.

Further, a cylindrical main body portion 17 supported by the mounting cylinder 13 and defining the storage chamber R ₂ therein is suspended in the screw cylinder 6. In the illustrated example, a seal cylinder 19 that is liquid-tightly fitted to the inner periphery of the screw cylinder 6 is suspended from the back surface of the top wall 18 that extends from the upper end edge of the mounting cylinder 13, and a cup-shaped member that will be described later is disposed inwardly. a cap-shaped member B ₁ in which the seal cylinder 20 and vertically to closely fitted to the peripheral wall, to form a second container with a bottomed cylindrical cup-shaped member B ₂ having an open upper end. Cup B ₂ is a bottomed cylindrical erected a peripheral wall 22 of the circumferential region of the bottom wall 21, between the reduced diameter portion of the seal cylinder 20 and the mounting tube 13 the upper end than the upper edge of the peripheral wall 22 Closely fitted. Further, on the outer surface a predetermined position of the peripheral wall 22 and projecting a plurality of ribs 25 spaced circumferentially spacing, place a cup-shaped member B ₂ its lower surface abutting engagement was sealed on the upper surface of the flange 9 It can be locked with. In addition, the outer periphery of the peripheral wall 22 immediately below the rib 25 is tightly fitted to the inner surface of the mounting base 7a, and the upper and lower portions are sealed at this portion, thereby forming a double seal structure with the seal cylinder 19. Therefore, even if the container falls down before opening, it is possible to prevent the stored item in the first container from going above the seal portion. As a means for locking the second container B at a predetermined position, the peripheral wall 22 of the portion is formed in a thick portion, or the peripheral wall 22 of the portion is bulged instead of the above-described configuration in which the rib 25 is formed. The lower surface of the flange 9 may be abutted and locked with the upper surface of the flange 9.

  The second container B is provided with an annular thin broken line 23. The thin broken line 23 is configured to be broken when the second container B is unscrewed and the stored item in the second container B falls into the first container A. The thin breaking line 23 is provided around the peripheral wall 22 of the main body portion 17, but is not limited thereto, and may be a position where the stored item in the second container B can drop when it is broken. Further, an annular surface 24 in the form of an upward stepped portion is provided. When the annular surface 24 is pressed by the locking portion 7, the thin breaking line 23 is provided at a position where it can be broken. Therefore, for example, when the thin-walled fracture line 23 is provided on the peripheral wall 22 of the main body, it is provided on at least the peripheral wall 22 below. In the illustrated example, the lower surface of an annular recess formed on the outer surface of the peripheral wall 22 is configured.

In the two-type mixing container configured as described above, for example, liquid and solid containers are stored in the first container A and the second container B, respectively, and are mixed and used at the time of use. In use, when the mounting cylinder 13 of the second container B is rotated in the screwing direction from the state of FIG. 1, the breaking portion 14 is broken and then screwed up. At this time, the main body portion 17 also tries to rise in a similar manner. However, the annular surface 24 comes into contact with the engaging portion 7 to prevent the main body portion 17 from rising, and the thin broken line 23 is broken, as shown in FIG. Thus, the stored item in the second storage chamber of the second container B falls into the first storage chamber of the first container A and mixes with the stored item in the first storage chamber. At this time, the separated bottom wall 21 falls into the first storage chamber R ₁ in the first container A. Then, if necessary, after the mixture is stirred, the mixed container can be taken out by unscrewing the second container B.

  In addition, although the material which forms each said member can be selected variously, forming with a synthetic resin is preferable.
