Description

0.1 C j A p C) q Z a Hair Tonic Application and Scalp Pattinq Instrument

This invention relates to a hair tonic V applicator, and more particularly to an instrument for applying hair tor)ic to the scalp of a user and patting the scalp as the hair tonic is applied.

In a known method for toning the scalp of' the user by scalp patting, a hair tonic is applied to the scalp of the user which is then massaged slightly with the ends of fingers of the user and patted with a scalp-patting brush to stimulate the scalp so as to enhance the blood flow in the capillaries thereof, whereby hairs in the scalp are prevented from failing out and dandruff and excess sebum are removed from the scalp.

Hitherto, application of the hair tonic and patting of the scalp are sequentially conducted by the use of separate instruments, i.e. a hair tonic applicator and a scalp-patting brush, so that the fingers of the user tend to be smudged with the hair tonic when the user massages his scalp after application of the hair tonic. In this conventional method, in order to prevent a scalp-patting brush from being smudged, it is necessary to conduct patting of the scalp with the brush after the hair tonic has been removed from the user's fingers. However, this is very cumbersome.

Embodiments of this invention resolve the above cumbersome work by providing an instrument for conducting hair tonic application to eo the user's Scalp and patting of the scalp in an easy manner.

Embodiments of this invention make it possible to apply hair-tonic to the scalp and pat the scalp in an easy manner using a single instrument.

In addition, embodiments of this invention make it possible to meter the hair tonic to the scalp easily, so that the user is released from cumbersome metering of the hair tonic.

According to the present invention, there is provided an instrument for applying hair tonic to the scalp and patting the scalp, comprising:

2 a hair tonic reservoir which serves as a main body of a hair tonic applicator and a scalp patting brush; a valve unit having a valve stem, mounted in the reservoir; a front cap mounted on a front portion of the reservoir, the front cap including a sleeve portion which communicates with the reservoir via the valve unit; a brush mount including a brush means and a pole projecting from its front surface, a bore extending in a direction generally parallel to the longitudinal axis of the reservoir to serve as a ventilation hole, and a hair tonic communication hole communicating with the brush means and being mounted on the valve stem of the valve unit so as to be axially slidable together with the valve stem to form a hair tonic meteing chamber at a time when the valve unit is opened; and a sealing ring mounted between the brush mount and an inner wall of the sleeve portion of the front cap.

A non-limiting embodiment of this invention will be described in detail with reference to the accompanying drawings in which:- Figure 1 is a longitudinal sectional view of the instrument of an embodiment of this invention for applying hair tonic to the user's scalp and patting the scalp; and Figure 2 is a front view of the instrument shown in Figure 1.

Referring to the drawings, the hair tonic applicator and a scalp- patting instrument comprises a hair tonic reservoir 1 which also serves as the main body of the instrument. In a front opening portion of the reservoir 1 is mounted a valve unit 6 comprising a valve seat 2, valve support 3, valve spring 4 and a valve stem 5.

A front cap 9 includes in its front-end portion a sleeve portion 7 having a predetermined longitudinal length and a front opening. The front cap 9 is threadably connected with the front end of the reservoir 1.

J 3 A central bore 8 is provided in the front cap 9 and extends longitudinally with respect thereto.

A brush mount 17 is slidably Mounted in the sleeve portion 7 of the front cap 9. At least one brush 13 is implanted in the front surface of the brush mount 17 for applying hair tonic to the' user's scalp. There is no limitation as to the number of brushes 13 and their position, and the brush 13 is implanted in a conventional manner. The brush 13 is sufficiently resilient to permit the front end of a pole 10 of the brush mount 17 to contact the scalp and also is sufficiently stiff to permit the user to pat the scalp.

A hair tonic communication bore 11 lies behind the brush 13 in the brush mount 17 as shown in Figure 1, through which communication bore 11 the hair tonic is metered to the brush 13.

The pole 10 projects forwardly from a central portion of the front is surface of the brush mount 17. The pole 10 of the brush mount 17 is slightly shorter than the brush 13. By means of the pole 10, the brush mount 17 is axially pushed toward the reservoir 1. The number and positions of the pole(s) 10 are suitably selected.

A bleed-hole 14 in the brush mount 17 serves as a ventilation hole and extends between the front and rear surfaces of the brush mount 17.

The diameter of the ventilation hole 14 is sufficiently small to prevent the hair tonic from dropping out of the ventilation hole 14. The number of the ventilation holes 14 is suitably selected.

A sealing ring or 0-ring 15 is mounted in an outer peripheral surface of the brush mount 17 as shown in Figure 1, and provides a watertight seal between the brush mount 17 and the inner wall of the sleeve portion 7 of the front shaft 9 so that a hair tonic metering chamber 19 is formed in the sleeve portion 7 of the front cap 9.

A supporting rod 16 projects rearwardly from a central portion of a rear surface of the brush mount 17. The rear end of the supporting rod 16 is connected to the front end of the valve stem 5 of the valve unit 6 so that the supporting rod 16 is interlocked with the valve stem 5 in operation.

The length of the supporting rod 16 is selected so that the hair tonic metering chamber 19 is formed between the rear surface of the brush mount 17 and the rear surface of the inner wall of the sleeve portion 7 of the front cap 9 in a condition shown in Figure 1 in which the valve stem 5 is seated on the valve seat 2 of the valve unit 6, i.e. in a condition in which the pole 10 of the brush mount is not pushed by the user.

In operation of the hair tonic application/scalp patting instrument illustrated in Figures 1 and 2, when the brush 13 of the instrument is pressed strongly against the scalp, the brush mount 17 is moved axially rearwards so that its rear end is brought into contact vith the rear wall surface of the sleeve portion 7 of the front cap 9, whereby the volume of the hair tonic metering chamber 19 reduces to substantially zero. At this time, the valve stem 5 of the valve unit 6 is also moved axially rearwards to open the valve unit 6. Then, the user releases the pressure from the pole 10 of the brush mount 17, so that the brush mount 17 is axially moved forward to return to its initial position. During this return cycle of the brush mount 17, i.e. until the valve unit 6 is again closed, the hair tonic flows into the hair tonic metering chamber 19 from the reservoir 1 through the bore 8. When the valve stem 5 is seated on the valve seat 2 of the valve unit 6, the flow of the hair tonic to the metering chamber 19 ceases.

Then, by capillary action, the brush 13 of the brush mount 17 absorbs the hair tonic in the metering chamber 19 through the hair tonic communication bore 11 of the brush mount 17. After that, the patting operation of the scalp is conducted. When the hair tonic received in the metering chamber 19 is exhausted, the user pushes the pole 10 of the brush mount 17 again to permit the hair tonic in the reservoir 1 to flow into the hair tonic metering chamber 19.

The hair tonic application/scalp patting instrument of Figures 1 and 2 is made of conventional material such as plastics and the like.
