In the case of making it possible to jet (inject) a foamed content liquid (hereinafter, also referred to as “foam”) in a distant jet shape based on a conventional foam discharge container as described in Patent Document 1. For example, it is conceivable to set the discharge port at the tip of the nozzle to a narrowed shape. However, with such a configuration, when the squeeze operation is started first, the bubbles can be ejected vigorously by squeezing rapidly (strongly), but the bubbles can be ejected vigorously by squeezing slowly (weakly). Bubbles will drip from the discharge port without. In addition, when performing a continuous squeeze operation, even if the squeeze operation is performed suddenly, first, the bubbles remaining inside the nozzle after the ejection by the previous operation drips from the ejection port, and then the foam ejection starts. It ends up.

Since the foam discharge container 1 according to the present embodiment has a pressure accumulator portion 10 capable of accumulating the foam-like content liquid supplied to the inside of the nozzle 4 and injecting it to the outside, the foam is ejected without dripping. can do. That is, when the squeeze operation is first performed, even if the squeeze operation is performed slowly, the bubbles can be ejected after being accumulated to a predetermined pressure by the accumulator unit 10, so that the bubbles can be ejected without dripping from the discharge port 14. Further, even when the squeeze operation is continuously performed, the bubbles remaining inside the nozzle after the ejection by the previous operation can be ejected after accumulating the pressure to a predetermined pressure by the accumulator unit 10. Therefore, the foam discharge container 1 according to the present embodiment can inject bubbles 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 accumulator portion 10 is composed of the slit valve 11, the foam can be ejected 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 in which the slit valve 11 curves convexly toward the proximal end side of the nozzle 4, and the slit 11a is formed in the convex curved wall 11b. Therefore, while the bubbles can be effectively accumulated inside the nozzle 4 during the squeeze operation, the slit 11a can be smoothly opened and air can be introduced from the outside when the container body 2 is restored and deformed after the squeeze operation. Since the foam discharge container 1 according to the present embodiment can close the discharge port 14 with the lid body 15, it is possible to suppress the sticking of the content liquid to the slit 11a and realize stable foam injection.

The above description merely shows one embodiment and does not limit the scope of claims. The embodiments may be modified in various ways based on the basics of the present disclosure.

For example, the accumulator portion 10 is not limited to the slit valve 11. The configuration of the slit valve 11 can be changed. Due to the restoration deformation of the container body 2 after the squeeze operation, an outside air introduction path capable of introducing air from the outside into the inside of the container body 2 without going through the nozzle 4 may be provided. In this case, a check valve may be provided to block the outside air introduction path during the squeeze operation, while opening the outside air introduction path when the container body 2 is restored and deformed after the squeeze operation. The foam-like content liquid may be directly injected from the accumulator portion 10 to the outside without providing the discharge port 14 at the tip portion of the nozzle 4. 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 introduction port capable of introducing air from the outside between the inner layer body and the outer layer body. It may be a double container.
