Description

[Detailed explanation of the idea] "Industrial application field" This case relates to a foam brush.

``Problems to be solved by conventional techniques and ideas'' Conventionally, there are foaming brushes that eject foamy hair conditioners or the like from the inside. This foaming brush usually has a large number of brittles etc. protruding from the surface of the base, a foam passage is provided in the longitudinal direction within the base, and the proximal end of the foam passage is connected to the foaming means, and A plurality of through holes for opening a foam flow path are arranged on the brush surface of the base body along the foam flow path.

However, the conventional devices had the disadvantage that the state of foam ejection from the through holes was unbalanced, and most of the foam was ejected from the through holes close to the foaming means, and almost no foam came out from the through holes further away.

The present invention attempts to eliminate such conventional drawbacks.

``Means for Solving the Problems'' As shown in the drawing, the present invention consists of a brush with a large number of brittle etc. protruding from the surface of the base.
A foam flow path is provided in the longitudinal direction, the base end of the foam flow path is connected to the foaming means, and the foam flow path is formed so that the cross-sectional area thereof gradually increases as the distance from the foaming means increases. , a plurality of through holes opening the foam flow path are arranged along the foam flow path on the brush surface of the base body.

``Effect'' With the above structure, the cross-sectional area of the foam flow path increases as the distance from the foaming means increases, so the amount of foam increases as the distance from the foam flow path increases, and as a result, all of the foam is It ejects uniformly or almost uniformly from the through holes.

"Embodiment" Part 1 FIGS. 1 to 3 show a first embodiment. The one in this example is made of synthetic resin.

In the figure, 1 indicates a large number of brittle 2 on the surface.
3 is a foam flow path provided in the longitudinal direction within the base, 4 is a foaming means connecting the base end of the foam flow path, and 5 is a foam flow path provided on the brush surface 1a of the base A plurality of through holes open the foam flow path.

The base 1 has a front member 11 and a back member 12 that are integrally provided with brittle 2, which are stacked together, hook-shaped locking edges 111, 111 are provided on both sides of the front member 11, and the base member 1 is held by the back member 12. A part of the locking edge and a corresponding positioning recess 11 in the back member 12 are provided at appropriate positions.
2 and 112 and convex portions 121 and 121 are provided to fit each other.

Further, a connecting ring 122 to be fitted into the foaming means 4 is integrally provided at the lower end of the backing member 12, and a projecting piece 12 extending from the lower part of the backing member 12 onto the connecting ring 122 is provided.
3 is integrally protruded, and a small fitting cylinder 12 is provided on the lower surface of the protruding piece.
4 is vertically installed, and the small fitting cylinder is communicated with the foam flow path 3.

The foam flow path 3 is formed by providing a groove 31 on the inner surface of the backing member 12 and using this as the main flow path, and the lower end of the groove is connected to the small fitting cylinder through a horizontal hole 32 provided in the protrusion 123. 124.

Moreover, the foam channel 3 has, in its concave groove 31,
The cross-sectional area is formed to gradually increase as the distance from the bubbling means 4 increases.

The foaming means 4 is an aerosol can with a stem 41 protruding from the center of the upper surface, and foam is ejected from the stem by pushing the stem. A mating tube 124 is fitted.

The through holes 5 are formed in the front member 11 in correspondence with the grooves 31, along the foam flow path, and are made smaller as they are closer to the foaming means and gradually larger as they are farther away. It is arranged as follows.

Note that the size of the through holes 5 may be appropriately determined as long as it corresponds to the cross-sectional area of the foam flow path 3.

Because of the above configuration, the protruding piece 12 of the back member 12
When 3 is pressed, the stem 41 of the aerosol can is pushed in, and foam is ejected from the stem, which passes through the foam flow path 3 and ejects out from each through hole 5 in a uniform or nearly uniform state.

Part 2 FIGS. 4 to 8 show a second embodiment. The one in this example is also made of synthetic resin.

In the figure, 1 indicates a large number of brittle 2 on the surface.
3 is a foam flow path provided in the longitudinal direction within the base, 4 is a foaming means connecting the base end of the foam flow path, and 5 is a foam flow path provided on the brush surface 1a of the base A plurality of through holes open the foam flow path.

In the base body 1, a mounting member 15 is slidably fitted to the lower outer periphery of a main member 14 having integrally protruding bristles 2, and a vertically elongated guide hole 151 is provided at the upper rear surface of the mounting member to accommodate this. A protruding piece 141 is integrally provided to project from the main member 14, and the protruding piece is inserted into the guide hole 151 so as to be movable up and down, and a lock lever 153 is integrally attached to the lower part of the back surface of the mounting member 15 via a hinge 152. The tip of the lock lever is engaged with the protrusion 141.

The foam channel 3 is open at the top and bottom, and has a plug 33 at the top end.
It is closed by mating. Further, the foam channel 3 is formed so that its cross-sectional area gradually increases as it becomes farther away from the foaming means 4.

The foaming means 4 is an aerosol can with a stem 41 protruding from the center of the upper surface, and foam is ejected from the stem by pushing the stem. The lower end of the flow path 3 is fitted.

The through holes 5 are arranged along the foam flow path and are arranged such that the closer they are to the foaming means, the smaller the holes are, and the farther away they are, the larger the holes are.

The size of the through-holes 5 may be appropriately determined as long as it corresponds to the cross-sectional area of the foam channel 3.

With the above configuration, lock clever 153
Press to unlock the protrusion 141, and then remove the protrusion 14.
1 is pushed down, the stem 41 of the aerosol can is pushed in, and foam is ejected from the stem, which passes through the foam flow path 3 and is ejected from each through hole 5 uniformly or nearly so to the outside.

"Effect of the invention" According to the present invention, the cross-sectional area of the foam flow path gradually increases as the distance from the foaming means increases.
The ejection of foam from each through hole can be made uniform or nearly so, and the drawbacks of the conventional method can be eliminated.
