In a preferred embodiment of the present invention, it is preferable that a plurality of fitting holes for fitting the projections are formed in the mounting board. In this case, by fitting the protrusion into the hole, the protrusion and the mounting board can be positioned more stably.

In a preferred embodiment of the present invention, it is preferable that the mounting substrate is mounted on the main body by ultrasonic welding. In this case, the space between the mounting board and the main body can be firmly bonded.

[0009]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a front view showing an embodiment of a mounting board having a plurality of soft projections according to the present invention, and showing a massage device for performing massage of a body or the like.

The massage device according to the present embodiment has a holding portion 10 for holding by a user attached to a main body portion 20 and an attachment substrate 40 having a plurality of soft projections 30 attached to the main body portion 20. is there.

The gripping portion 10 may be hollow or solid, as appropriate. In the former case, the grip portion 10
Can be formed as a container containing a required liquid such as cosmetics, and the main body portion 20 and a soft protrusion 30 described later can be configured to have liquid permeability. In this case, it is possible to supply the liquid contained in the container to a required portion such as a body through the main body portion 20 and the projection 30 of the massage device.

The main body 20 is made of, for example, polyethylene.
Those formed of an olefin-based resin such as polypropylene are preferred. The plurality of protrusions 30 are made of an elastomer that is a soft material having relatively low compatibility with the main body portion 20;
Each of the projections 30 has a seat portion 31 described below, the lower portion of which is integrally formed. The mounting substrate 40 is made of a material having relatively high compatibility with the main body portion 20 of the massage device, preferably, the same resin as the main body portion 20.

FIGS. 2A, 2B and 3 illustrate a method of manufacturing the mounting substrate 40 having the above-described soft projection 30. FIG. In particular, FIG. 2A is a side view showing a seat 31 in which each of the projections 30 is integrally formed.
(B) is a sectional view showing the mounting board 40 itself.
FIG. 3 is a cross-sectional view showing a state in which a substrate 40 having a plurality of protrusions 30 is attached to the main body portion 20 of the massage device.

As shown in FIG. 2A, each of the plurality of projections 30 is integrally formed with a lower portion thereof to form a seat portion 31. In this case, it is preferable that the projections 30 are arranged at a predetermined interval, and the seat surface 31a on the side from which the projections 30 protrude and the rear surface 31b thereof have a substantially flat shape.

As shown in FIG. 2B, the mounting board 40 has a shape in which the seat 31 of the projection 30 is integrally fitted inside, and is on the opposite side to the surface 40a on the side where the projection 30 projects. On the back surface 40b, a fitting groove 4 in which the seat portion 31 is fitted internally.
2 are provided.

A specific structure when the projection 30 is attached to the main body portion 20 is as shown in FIG. Protrusion 3
0 indicates that the seat portion 31 is internally fitted in the fitting groove 42 of the mounting board 40. Also, the surface 4 of the mounting substrate 40
As shown in FIG. 2B, a plurality of fitting holes 41 for fitting each of the projections 30 is formed in Oa.

In this case, since the projection 30 is fitted into the hole 41 of the mounting board 40, the mounting board 40 is
Of the projections 30 while allowing the projections 30 to move freely without falling out.
And the mounting board 40 can be positioned more stably.

FIG. 4 is a partial cross-sectional view showing a state where the main body portion 20 is assembled to the grip portion 10 of the massage device from the side.

As shown in FIG. 4, the main body portion 20 is attached to the grip portion 10 in a cap shape. The mounting portion includes, for example, an inward projection 21 provided inside the main body portion 20 and a grip portion 10. And a groove 11 provided on the outside. However, the inward projection 21 of the main body portion 20 and the groove 11 of the grip portion 10 are a fitting portion formed by a groove formed on the main body portion 20 and an inward projection formed on the grip portion 10. Alternatively, the inward projection and the groove may be provided over a part or the whole in the circumferential direction.

As shown in FIG. 4, a concave portion 22 for mounting the mounting substrate 40 to the main body portion 20 is formed on the outer surface of the main body portion 20, and the mounting substrate 40 is fitted into the concave portion 22. Combine. Specifically, it is preferable to attach the frame portion 43 of the mounting substrate 40 to the inner edge surface of the concave portion 22 of the main body portion 20 by ultrasonic welding. In this case, the mounting substrate 40 and the main body portion 20 are attached.
Can be firmly bonded.

As is apparent from the above description, according to the present invention, the projections 30 made of an elastomer having a relatively low compatibility with the main body 20 are relatively high in the compatibility with the main body 20. Since it is attached to the main body portion 20 via the mounting substrate 40 made of a material, it is easy to attach the projection 30 made of an elastomer having relatively low compatibility with the main body portion 20 to the main body portion 20, so that productivity is improved. Improved and reduced production costs.

Further, according to the present invention, it is not necessary to adopt a production method such as insert molding using the mounting substrate 40 as an insert part. Therefore, the cycle time required for mounting the soft projection 30 on the mounting substrate 40 is reduced. Is done. In addition, by sharing or standardizing the components attached to the main body 20, it is possible to efficiently cope with a design change of the main body 20.
