Kind Code:
A1
Abstract:
[Problem] To provide a foaming tool that the user shakes manually up and down or left to right. [Solution] The tool comprises: a container part, which has a inner space that extends vertically and has a grip shape on the outside; an opening/closing part; and a coil spring, which has a constant winding diameter and is capable of moving freely in the vertical direction inside the container part. A liquid material, in which a substance to be dispersed and a liquid are mixed, and the coil spring are placed in the container part. A silencer is provided on an end of the coil spring. The invention comprises: a coil spring-contacting part, which supports one winding of an end of the coil spring by contacting 80 percent of the planar area formed by the one winding; first and second perpendicular walls, which are two perpendicular walls that are perpendicular to the coil spring-contacting part and also perpendicular to the coil constituting the coil spring, the walls being provided at the limit of where the coil spring-contacting part contacts the coil spring; and a cylindrical wall section, which is a cylindrical wall extending perpendicularly on the opposite side of the coil spring-contacting part from the coil spring and has the outer diameter of the coil spring as the inner diameter thereof. Two holes through which the coil constituting the coil spring can pass are provided side-by-side in the direction in which the coil spring extends in each of the first and second perpendicular walls.
