However, the present invention is not limited to these, although air and liquid can be mixed and foamed more reliably.

  The foam generating body 43 is assembled inside the mission pipe 40, and the downstream annular convex section 40d of the mission pipe 40 is located between the upstream annular convex section 43b1 and the downstream annular convex section 43b2 of the foam generating body 43, and the mission A spring 44 is disposed between the upstream annular convex portion 40 c of the pipe 40 and the foam generating body 43. The spring 44 always urges the foam generating body 43 to the downstream side, and the upstream annular convex portion 43 b 1 of the foam generating body 43 is in contact with the downstream annular convex portion 40 d of the mission pipe 40. The foam generating body 43 is pushed by the pressure of the air sucked from the outside through the foam discharge passage 32 and moves against the spring 44, and the air from the outside passes through the foam discharge passage 32 and the external air introduction passage 48. It introduce | transduces in a liquid and makes it inhalable further in the space in the container main body 10. FIG.

  The mission pipe 40 is provided with an air check valve 60. As shown in FIGS. 3, 7, and 8, the mission pipe 40 is made of an elastic body and has a negative or positive slit 60a. In the air check valve 60, the slit 60a is opened when the container body 10 is pressed and deformed, and air is introduced into the gas-liquid mixing chamber 42 from the air introduction passage 51 (FIG. 8A). When the pressure deformation of the container body 10 is released, the slit 60a is closed to block the introduction of air from the gas-liquid mixing chamber 42 to the air introduction passage 51 (FIG. 8B).

  As described above, the foam discharge container 1 includes the air introduction passage 51 that communicates with the space in the container body 10, the liquid introduction passage 41 that introduces the liquid in the container body 10, the air introduction passage 51, and the liquid introduction passage 41. A gas-liquid mixing chamber 42 communicating with the gas-liquid mixing chamber 42 and a foam discharge passage 32 communicating with the downstream side of the gas-liquid mixing chamber 42 are used as shown in FIG.

  The use of the foam discharge container 1 will be described in detail. As shown in FIG. 9A, the body of the container body 10 is sandwiched between the thumb and other fingers with the foam discharge passage 32 facing downward. When the container body 10 is pressed and deformed in this manner, the air inside the container body 10 is introduced from the air introduction passage 51, and the slit 60a of the air check valve 60 is opened by the pressure of the air. In addition to introducing air into the gas-liquid mixing chamber 42, the liquid is introduced into the gas-liquid mixing chamber 42 from the liquid introduction passage 41.

  That is, the body portion of the container body 10 is pushed from both sides with the thumb and other fingers sandwiched between them, but the foam generating body 43 is biased by the spring 44, and the upstream annular convex portion 43b1 of the foam generating body 43 is connected to the mission pipe. Since the foam generating body 43 is in contact with and sealed against the stepped portion of the foam discharge cap 30, the liquid in the container body 10 is allowed to flow into the air introduction passage 51. Not introduced from. Therefore, the liquid in the container body 10 is introduced into the gas-liquid mixing chamber 42 only from the liquid introduction passage 41.

  And the upstream annular convex part 43b1 of the foam production | generation body 43 is contact | abutted and sealed by the downstream annular convex part 40d of the mission pipe 40, and the foam production | generation body 43 is contact | abutted and sealed by the step part of the foam discharge cap 30. Therefore, in the gas-liquid mixing chamber 42, air and liquid are mixed, and further, the bubbles are generated by mixing the air and liquid by passing through the bubble generator 43. The obtained bubbles are rectified by flowing through the passage 33a of the bubble rectifying unit 33 in the bubble discharge passage 32, and the discharged bubbles can be made uniform.

  When the pressure deformation of the container body 10 is released by releasing the pressure between the thumb and other fingers, the pressed body of the container body 10 is restored to its original shape as shown in FIG. The suction force works to return, and the container body 10 returns to its original shape. Due to the suction force at this time, air from the outside is introduced from the bubble discharge passage 32 through the passage 33a of the bubble rectifying unit 33, and the foam generator 43 resists the spring 44 by the pressure of the air from the outside. The foam generating body 43 moves away from the step portion of the foam discharge cap 30 and becomes a passage, and the downstream annular convex portion 43b2 of the foam generating body 43 comes into contact with the downstream annular convex portion 40d of the mission pipe 40. Sealed. Therefore, the air from the outside is introduced into the liquid together with the bubbles remaining in the bubble discharge passage 32 from the bubble discharge passage 32 via the external air introduction passage 48, and the air is further sucked into the space in the container body 10. At this time, a part of the air from the outside is introduced into the gas-liquid mixing chamber 42 through the foam product 43, and the air is introduced into the liquid through the liquid introduction passage 41 together with the foam remaining in the foam product 43. Then, it is sucked into the space inside the container body 10.

  In this embodiment, the passage area of the external air introduction passage 48 is larger than the passage area of the liquid introduction passage 41 and is about five times or more. Although it is sucked from a passage formed away from the part, since the foam generating body 43 becomes a resistance, most is introduced into the container body 10 via the external air introduction passage 48. Even if air from the outside passes through the foam generating body 43, it is negligible, and since the air check valve 60 is closed, it is introduced into the container body 10 from the liquid introduction passage 41. In this way, only the bubbles and the outside air that have entered the container body 10 rise as an abdomen at the upper part and become an air reservoir in the upper part of the container body 10. In this way, it is possible to discharge the foam in a constant amount by repeating the pressing pressure deformation and the pressing pressure deformation of the container body 10.
