In other words, the lid body 30 and the inner plug body 20 behave integrally.

FIG. 8 is a schematic view showing an operation procedure when the first agent and the second agent are mixed by opening the two-agent mixing container according to the present embodiment, and FIG. 9 is the first agent and the second agent. It is the schematic for demonstrating the motion of the stirring blade at the time of mixing. Next, with reference to these FIG. 8 and FIG. 9, the operation procedure when mixing the first agent 41 and the second agent 42 by opening the two-component mixing container 1 according to the present embodiment, and stirring at that time The movement of the wing 22a will be described. 9 is a perspective view of the second storage chamber S2 as viewed from above when the lid 30 is removed. In FIG. 9, the lid 30 and the second agent 42 are not shown. Yes.

When mixing the first agent 41 and the second agent 42 by opening the two-agent mixing container 1 according to the present embodiment, first, as shown in FIG. One lid 30 is positioned vertically upward and the container body 10 is erected so as to be positioned below the lid 30.

Next, as shown in FIG. 8 (B), the lid 30 is removed from the container body 10. Specifically, the lid body with respect to the mouth portion 13 is released so that the state in which the female screw portion 36 provided in the lid body 30 is engaged with the male screw portion 15 provided in the container body 10 is released. 30 is rotated in the direction of the arrow DR2 shown in the figure (the direction opposite to the direction of the arrow DR1 described above).

At this time, since the inner plug body 20 rotates together with the lid body 30 in conjunction with the rotation of the lid body 30 as described above, as shown in FIG. 9, the inner plug body 20 is in the second storage chamber S2. It rotates around the axis AX as the center of rotation. Along with this, a plurality of stirring blades 22a provided projecting outward from the outer peripheral surface of the shaft portion 22 rotate in the direction of the arrow AR1 in the figure so as to stir the second agent 42. As a result, the second agent 42 moves.

Here, since the stirring blade 22a has a flat plate shape extending in the vertical direction as described above, the stirring blade 22a is parallel to the axis AX direction of the inner plug body 20. In addition, the lid body 30 has an agitation surface that faces the downstream side in the rotation direction of the lid body 30 (that is, the arrow DR2 direction) when the lid body 30 is removed from the mouth portion 13 of the container body 10. Therefore, the movement of the second agent 42 described above is caused by the movement of the second agent 42 by the second agent 42 being pushed away by the agitating surface when the stirring surface moves in the direction of the arrow AR1 shown in the drawing. Will occur throughout.

At the same time, as shown in FIG. 8 (B), the inner plug that is in close contact with the press-fit portion 11d of the container body 10 by moving the lid body 30 away from the container body 10 is provided. The plug part 21 of the body 20 is pulled out from the pressed-in part 11d. Along with this, a gap is generated between the body portion 11 of the container body 10 and the plug portion 21 of the inner plug body 20, and the first storage chamber S1 and the second storage chamber S2 are in communication with each other.

Furthermore, at substantially the same time, the close contact between the mouth 13 of the container body 10 and the outer vertical wall 34 of the cover body 30 is released by moving the cover body 30 away from the container body 10. become. Along with this, a gap is also generated between the container body 10 and the lid body 30, and the second storage chamber S2 and the space outside the two-component mixing container 1 are in communication with each other through the gap. .

As a result, the second agent 42 stored in the second storage chamber S2 is between the body portion 11 of the container body 10 and the plug portion 21 of the inner plug body 20 due to its own weight and the above-described movement. The drop starts toward the first storage chamber S1 through the gap generated in (i.e., in the direction of the arrow AR2 shown in the drawing).

Thereafter, as shown in FIG. 8C, at the timing when the lid body 30 is completely removed from the container body 10 and the inner plug body 20 is extracted, all of the second agent 42 has already dropped and the first In this state, the first agent 41 and the second agent 42 are mixed as the two-component mixing container 1 is opened.

Here, at the time of mixing described above, the second agent 42 is agitated and moved by the rotation of the stirring blade 22a, so that the body portion 11 of the container body 10 and the plug portion 21 of the inner plug body 20 are in motion. When the gap is generated between the second agent 42 and the first storage chamber S1 side, the second agent 42 starts to drop immediately through the gap. That is, in a small state before the gap between the container body 10 and the inner plug body 20 is formed sufficiently large (in other words, in the state where the second agent 42 is almost stationary, the second tension is caused by the surface tension. Even in a state in which the agent 42 stays and a small gap is formed so that the drop cannot be started), the second agent 42 can fall by breaking the surface tension by the movement of the second agent 42. Become.

Therefore, in the two-component mixing container 1 according to the present embodiment, the liquid first agent 41 and the second agent 42 can be mixed almost simultaneously with opening, and the first agent 41 and the second agent 42 are mixed. In addition, the intended purpose of being able to mix the first agent 41 and the second agent 42 can be achieved quickly without delay.

Further, in the two-component mixing container 1 according to the present embodiment, since the second agent 42 can be positively moved at the time of opening, the second agent 42 is somewhat viscous. Even when it is a liquid or when the second agent 42 is a solid such as a powder or a granule, it can be quickly dropped toward the first agent 41, and further, these can be used as inner plugs. It can also be suppressed that it remains in the body 20.

The two-component mixing container 1 described above uses an inner plug provided with a stirring blade having a stirring surface parallel to the axial direction, but includes a stirring blade having a shape different from this. It is also possible to use a plug. 10 to 12 are perspective views of the middle plug body of the two-component mixing container according to the first to third modifications. The inner plugs 20A to 20C shown in FIGS. 10 to 13 can be provided in the two-component mixing container 1 in place of the inner plug 20 described above.

In the inner plug body 20A according to the first modification shown in FIG. 10, a part of the plurality of stirring blades provided in the shaft portion 22 is parallel to the axis AX direction of the inner plug body 20A. It is comprised by the stirring blade 22a which faces the downstream of the rotation direction (namely, arrow DR2 direction) of the cover body 30 at the time of removing the cover body 30 from the opening | mouth part 13 of the container main body 10. FIG.

On the other hand, in the inner plug body 20A according to the first modified example, the remainder excluding the part of the plurality of stirring blades provided in the shaft portion 22 intersects the axis AX direction of the inner plug body 20A. In addition, the lid body 30 faces the downstream side in the rotation direction (that is, the arrow DR2 direction) and, as it goes toward the downstream side, the lower end side of the middle plug body 20A (that is, the inner plug body 20A is placed inside the container body 10). Inclined so as to go from the bottom 12 side of the container body 10 in the inserted state toward the upper end side (that is, the mouth 13 side of the container body 10 in the state where the inner plug 20A is inserted into the container body 10). A stirring blade 22b having a stirring surface is used.

Further, in the inner plug body 20B according to the second modification shown in FIG. 11, all of the plurality of stirring blades provided in the shaft portion 22 intersect the axis AX direction of the inner plug body 20B, and the lid Agitating blade 22b having an agitating surface that faces the downstream side in the rotational direction of body 30 (ie, in the direction of arrow DR2) and has an agitating surface that inclines from the lower end side toward the upper end side as it goes toward the downstream side. It is configured.

Further, in the inner plug body 20C according to the third modification shown in FIG. 12, all of the plurality of stirring blades provided in the shaft portion 22 intersect the axis AX direction of the inner plug body 20B, and the lid A screw-shaped stirring blade having a stirring surface that faces the downstream side in the rotation direction of the body 30 (that is, the direction of the arrow DR2) and has a stirring surface that is inclined from the lower end side toward the upper end side toward the downstream side. 22c.

In the case of the two-component mixing container 1 having the inner plugs 20A to 20C as in the first to third modifications, the inclined stirring provided in the inner plugs 20A to 20C at the time of opening. Since the second agent 42 is positively pushed downward by the surface (that is, the stirring surfaces of the

stirring blades

22b and 22c), the second agent 42 is generated between the container body 10 and the inner plugs 20A to 20C. It becomes possible to send the second agent 42 more efficiently toward the gap. Therefore, it becomes possible to mix the first agent 41 and the second agent 42 more rapidly by using the intermediate plugs 20A to 20C having the above configuration.

In addition, the shape of the stirring surface provided in the stirring blade is not limited to the shape described above, and other shapes can naturally be adopted. Furthermore, it is not always necessary to provide a stirring blade so as to protrude from the shaft portion, and the second agent can be stirred by the shaft portion itself by configuring the shaft portion itself in a flat plate shape, a bent plate shape, or a curved plate shape. You may comprise.
