Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a squeeze-type foam discharging container for squeezing a container body to form a foam from a liquid material and air in the container body and discharging the foamed material to the outside. The present invention relates to a squeeze-type foam discharge container capable of instantly spraying a liquid coating agent as a foam.

[0002]

2. Description of the Related Art Conventionally, liquid wax for floors and liquid wax for cars have been provided by being filled in a single-hole type squeeze container or a trigger type spray container. A liquid substance is applied to and the applied area is wiped off with a cloth or the like before use.

[0003]

However, when a single-hole type squeeze container is used for coating as in the prior art, the liquid material often bounces from the coating surface, depending on the coating location, so that the liquid may reach beyond the target range. Even if you think that you have wiped off all the applied areas after the liquid has spattered, there are still traces of the liquid that have spattered after drying, and you have to wipe it again. Was there. Further, in the trigger type spray container, since the liquid substance spreads too much, it has a drawback that it cannot be applied in a narrow place and that it is often scattered.

Therefore, an object of the present invention is to provide a foam discharge container capable of reliably suppressing rebound from the application surface and applying to a narrow space.

The foam discharge device is provided with a liquid introduction path, an air introduction path, a gas-liquid mixing chamber, a foam, and a discharge port, and by squeezing the body of the container body, the liquid material in the container body and Air is introduced into the gas-liquid mixing chamber through the liquid introduction path and the air introduction path, and the mixed liquid and air are foamed with the foam to form a gas-liquid mixing volume ratio [volume of foam / (foam) The weight of the product / the density of the liquid)] is 1.1 to 10 and a foam discharge container for discharging the foam to the outside from the discharge port, wherein the foam is The above-mentioned liquid material that forms a film contains 3% to 30% of a non-volatile component, and the non-volatile component is capable of forming a film. Computing agent is to provide a foam discharge container, which is a coating solution mainly composed silicone or wax. In addition, in the foam discharge container of the present invention, in order to prevent the solidification of the non-volatile components accompanying the evaporation of the volatile components of the liquid from the discharge port, a cap for preventing evaporation when not in use may be provided. preferable. Further, in the present invention,% means% by weight unless otherwise specified.

In the foam discharge container of the present invention, by squeezing the body portion of the container body, the nonvolatile component contained in the container body is 3% to 30%, and the nonvolatile component can form a film. A coating agent, a coating agent liquid containing silicone or wax as a main component, and air are introduced into the gas-liquid mixing chamber through the liquid introduction passage and the air introduction pipe, and the coating agent liquid and air are further foamed by the foam. A foam is formed and the foam is discharged to the outside from the discharge port. Since the gas-liquid mixing volume ratio of the foam formed by the foam is 1.1 to 10, Bounce from the application surface is surely suppressed, and application can be performed within a target range.
