Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a foam ejector.
[0002]
[Prior art]
As a foam ejector, it was fitted to the container body that raised the mouth and neck from the squeezable cylindrical body, and the inner periphery of the mouth and neck, and a hole for pipe fitting was made in the center, and a small hole was made around it. An inner plug, a pipe with the upper end fitted into the pipe fitting hole at the center of the inner plug and suspended from the lower end of the container body, a foaming mesh stretched on the upper part of the mouth and neck, and an outer periphery of the mouth and neck What consists of a cap with a nozzle fitted by fitting a peripheral wall is known.
By squeezing the body part, the liquid in the container body part is transferred to the upper part of the small container through the pipe and the air in the upper part of the small container part through the small holes, respectively. It is configured such that it is uniformly bubbled through a mesh and ejected from a nozzle.
[0003]
[Problems to be solved by the invention]
In these foam ejectors, when the squeezing of the container body portion is released in order to perform the foam ejection again after the foam ejection, the formed unsprayed foam is formed in the upper part of the container body part through the upper part of the pipe or the small hole. In particular, when bubbles invade the upper part of the container body, the amount of air other than bubbles inevitably decreases, and when the body is squeezed again, the ratio of liquid to air changes significantly, and the balance is unstable. There was an inconvenience that only foam was possible.
[0004]
The present invention has been made in consideration of such points, and proposes an excellent bubble ejector that can always eject good bubbles and is easy to handle.
[0005]

In order to solve the above-mentioned problems, the foam ejector of the present invention has an air container body 2 having a squeezable body section 4 and is suspended and fixed in the container body with a gap around it, and a thin-walled body. The liquid container body 3 with the neck and neck 12 standing up from the upper end of the section 10, and the top plate 5 that closes the opening of the upper end of the air container body pass through the mouth neck 12 of the liquid container body and the tip jet outlet 17 A bubble ejection path A is provided with a discharge valve 18 at the lower end and a foaming layer 19 at the top, and communicates with the air into the foam ejection path between the discharge valve and the foaming layer. A check valve 26 that unilaterally introduces air from the container body is provided to make the bubble ejection path the gas / liquid mixing chamber A1, and an outside air introduction valve 28 that unilaterally introduces outside air into the air container body is provided. It was comprised as a foam ejector characterized by providing.
