However, in such a configuration, when the squeeze operation is first performed, bubbles can be ejected vigorously if squeezed suddenly (strongly), but bubbles can be expelled vigorously if squeezed slowly (weakly). Without bubbles falling from the discharge port. In addition, when performing squeeze operations continuously, even if the squeeze operation is performed suddenly, first, the foam remaining inside the nozzle after the discharge by the previous operation drips from the discharge port, and then the foam discharge starts. End up.

  An object of the present disclosure is to provide a foam discharge container that can inject bubbles without dripping down.

  One aspect of the foam discharge container includes a container main body that contains the content liquid, and a discharger attached to the container main body.

The nozzle body 17 has a straight cylindrical shape extending sideways while tilting slightly upward from the proximal end portion toward the distal end portion. As shown in FIG. 2, the nozzle tip member 18 includes an outer cylinder 19, a slit valve 11, and a support ring 20. The outer cylinder 19 includes a fitting cylinder 19a that fits to the outer peripheral surface at the tip of the nozzle body 17, a support cylinder 19b that continues to the tip side of the fitting cylinder 19a, and a support cylinder 19b that continues to the tip side of the support cylinder 19b. An intermediate cylinder 19c having a further reduced width, a distal end cylinder 19d that is connected to the distal end side of the intermediate cylinder 19c and has a smaller width than the intermediate cylinder 19c, and a lid 15 that is connected to the distal end of the distal end cylinder 19d via a hinge 16 have. A discharge port 14 is formed at the tip of the tip tube 19d. The discharge port 14 has a circular shape whose width is smaller than that of the nozzle 4 (nozzle body 4). The shape of the discharge port 14 may be elliptical or rectangular, for example, and can be changed. The lid 15 includes an inner fitting portion 15a that can be fitted to the discharge port 14, an outer fitting portion 15b that can be fitted to the outer peripheral surface of the intermediate cylinder 19c, and a knob that can be operated to open and close the lid 15. Part 15c. The inner fitting portion 15a is formed of a protrusion in this embodiment, but may be formed of, for example, a cylindrical convex portion, and the shape thereof can be changed as appropriate. In the present embodiment, the outer fitting portion 15b is formed of a rib, and can be fitted into a groove provided on the outer peripheral surface of the intermediate cylinder 19c. However, the outer fitting portion 15b may be composed of, for example, a rib that can be fitted between two ribs provided on the outer peripheral surface of the intermediate cylinder 19c, and the shape thereof can be changed as appropriate. The slit valve 11 includes a convex curved wall 11b, a cylindrical wall 11c that is continuous with the outer peripheral edge of the convex curved wall 11b, and a flange wall 11d that is continuous with the base end of the cylindrical wall 11c. The flange wall 11 d is fixed to the inside of the support cylinder 19 b of the outer cylinder 19 by the support ring 20.

  As shown in FIG. 1, in the present embodiment, the discharger 3 has a mounting cylinder 21 that is mounted on the mouth 2 a of the container body 2 and that is continuous with the base end of the nozzle body 17. A cylindrical holding wall 22 that constitutes the upper portion of the foaming chamber 6 is suspended from the base end portion of the nozzle body 17. A check valve 13 is fitted to the upper part of the outer peripheral surface of the holding wall 22. A hanging member 23 is fitted to the lower part of the outer peripheral surface of the holding wall 22. The hanging member 23 includes an intermediate member 24 fitted to the lower portion of the outer peripheral surface of the holding wall 22, a lower member 25 fitted to the lower end portion of the outer peripheral surface of the intermediate member 24, and a suction pipe fitted to the lower member 25. 26. A foaming chamber 6 is configured by the holding wall 22 and the hanging member 23. The drooping member 23 constitutes the liquid feeding section 7 and the air feeding section 8.

  Since the foam discharge container 1 according to the present embodiment has the pressure accumulating portion 10 that can accumulate the foam-like content liquid supplied to the inside of the nozzle 4 and inject it to the outside, the foam is discharged without dripping down the foam. can do. That is, when the squeeze operation is first performed, even if the squeeze operation is performed slowly, the bubbles can be injected after being accumulated to a predetermined pressure by the pressure accumulating unit 10, so that the bubbles can be ejected without dripping from the discharge port 14. In addition, when the squeeze operation is continuously performed, the foam remaining in the nozzle after the discharge by the previous operation can be injected after the pressure is accumulated by the pressure accumulating unit 10 to a predetermined pressure. Therefore, the foam discharge container 1 according to the present embodiment can inject the foam without dripping from the discharge port 14 even when the squeeze operation is continuously performed.

  In the foam discharge container 1 according to the present embodiment, since the pressure accumulating portion 10 is configured by the slit valve 11, the foam can be injected without dripping, despite the simple configuration. In the foam discharge container 1 according to the present embodiment, the slit valve 11 has a convex curved wall 11b that curves convexly toward the proximal end side of the nozzle 4, and the slit 11a is formed in the convex curved wall 11b. Therefore, bubbles can be effectively accumulated inside the nozzle 4 during the squeeze operation, while air can be introduced from the outside by smoothly opening the slit 11a when the container body 2 is restored and deformed after the squeeze operation. Since the foam discharge container 1 which concerns on this embodiment can obstruct | occlude the discharge outlet 14 with the cover body 15, sticking of the content liquid to the slit 11a can be suppressed, and stable foam injection can be implement | achieved.

  The foregoing description is merely illustrative of one embodiment and is not intended to limit the scope of the claims. Various modifications can be made to the above-described embodiment based on the basic matters of the present disclosure.

  For example, the pressure accumulating unit 10 is not limited to the slit valve 11. The configuration of the slit valve 11 can be changed. By restoring and deforming the container body 2 after the squeeze operation, an outside air introduction path through which air can be introduced from the outside into the container body 2 without using the nozzle 4 may be provided. In this case, a check valve may be provided that closes the outside air introduction path during the squeeze operation and opens the outside air introduction path when the container body 2 is restored and deformed after the squeeze operation. You may make it inject a foam-like content liquid directly from the pressure accumulation part 10 outside, without providing the discharge outlet 14 in the front-end | tip part of the nozzle 4. FIG. The container body 2 includes an inner layer body containing the content liquid and an outer layer body containing the inner layer body, and the outer layer body has an outside air inlet through which air can be introduced from the outside between the inner layer body and the outer layer body. A double container may be sufficient.
