Next, the usage mode and effect of the two-component mixing container of the present invention will be described.
First, a method for assembling the mixing container will be described. The second agent made of a liquid or powder different from the contents in the container main body A is placed inside the side cylinder wall 31 of the pressing member 23 of the inverted outer cap C. When the inner cylinder 4 of the inner cap B is covered and inserted, the engagement protrusion 10 of the inner cylinder 4 engages with the engagement protrusion 35 of the side cylinder wall 31 of the push-down member 23, The small diameter portion 9 of the cylinder 4 is fitted to the outer periphery of the side cylinder wall 31, and the inside of the side cylinder wall 31 is sealed.

  Further, when the annular flange 15 is engaged with the annular groove 28, the ratchet piece 13 and the ratchet teeth 27 are engaged, and the inner cap B and the outer cap C are integrated. An integrated inner / outer cap accommodating the second agent is obtained between the outer cylinder C and the side cylinder wall 31 of the outer cap C.

  Next, when the integrated inner and outer caps are fitted into the container mouth tube portion 1, as shown in FIG. 4A, the ratchet teeth 27 are engaged with the ratchet piece 13, and the screw 14 of the inner cap B is connected to the mouth tube. The upper wall 5 of the inner cap B comes into contact with the top surface of the mouth tube portion 1, and the lower end of the outer peripheral wall 21 of the outer cap C is located close to the shoulder portion 2. Thus, the assembly of the two-component mixing container is completed.

At the time of display at the store, even if the outer cap C is rotated with the container body A, the two-component mixing container can be lowered further because the inner cap B is in contact with the top surface of the container mouth tube 1. Even if the ratchet teeth 27 and the ratchet piece 13 do not mesh with each other even if they are rotated in the direction of opening the lid, the inner cap B cannot be removed from the container body A simply by spinning around.
Therefore, since the connecting piece 22 of the push-down member 23 is not cut, it is ensured that the two-component mixing container is unopened.

In use, when the pressing member 23 is pressed and pressed, the connecting piece 22 is cut and the pressing member 23 is lowered as shown in FIG. By 36, the fracture | rupture groove | channel 11 of the bottom wall 7 is cut | disconnected, a 2nd agent falls in the container main body A, and the content in the container main body A is mixed.
At that time, since the inner diameter of the large diameter portion 8 of the inner cylinder 4 is large, the side cylinder wall 31 of the push-down member 23 freely slides and reaches the reduced diameter small diameter portion 9. The lowering is stopped by the engagement protrusion 35 coming into contact with the upper end of the small diameter portion 9.

  Further, it is displayed that the opening has been made by cutting the connecting piece 22 and lowering the push-down member 23.

  When the push-down member 23 is lowered, the locking rib 34 engages with the rotation stop rib 12 of the inner cap B, and the push-down member 23 is rotated together with the inner cap B, so that the push-down member 23 is engaged. The convex portion 33 of the top wall 30 and the engaging leg 26 of the top wall 20 of the outer cap C engage with each other, and the inner cap B rotates with the rotation of the outer cap C. The two-component liquid mixture can be poured out.

When storing the remaining liquid after a certain amount of pouring, if the outer cap C is turned in the closing direction, the ratchet teeth 27 and the ratchet piece 13 are engaged with each other, and the protrusion 33 on the top wall 30 of the push-down member 23 The cap can be closed by engagement with the engagement leg 26 of the cap C top wall 20.
Therefore, the inner and outer caps can be freely opened and closed during use.

  In the above embodiment, the ratchet teeth 27 are provided on the outer cap C and the ratchet piece 13 is provided on the inner cap B. However, the position of the ratchet mechanism 13 may be reversed, and the shape of the ratchet mechanism is not limited to the embodiment.

  Even if the outer cap is turned, the inner cap does not turn, so unopened can be guaranteed, and the two components can be mixed by only pushing the push-down member with a small force. It can be used as a two-component mixing container for various uses such as medicines, cosmetics, and foodstuffs.
