Description

  The present invention relates to a brush for massaging the scalp for blood circulation promotion, hair growth and the like.

Conventionally, there are those that strike the scalp with a bristle and those that rub. The former is said to be effective in preventing blood loss and promoting hair growth by hitting the scalp. The bristle is made of a flexible material such as an elastomer and is made of a large diameter of several millimeters or a thick wooden Diameter or animal hair is used and widely used, but recently, hitting the scalp itself has problems because it damages the subcutaneous tissue composed of various cells such as capillaries and hair roots. Is said to lead to hair loss, and it has been pointed out that massage is a good way to stretch the scalp gently, such as twisting instead of striking. The latter is used because it has the same effect as described above by rubbing the scalp. The bristle is broadly divided into a soft and large-diameter type as described above, and a hard and small-diameter type having a diameter of less than 1 mm using animal hair or a synthetic resin monofilament. Regardless of the bristle, the stimulation to the scalp during massage is due to the single point of the bristle tip that contacts the scalp, is monotonous, and does not have a high massage effect. Further, many hard and small-sized bristle have an edged end surface, and the scalp is strongly stimulated and may hurt the scalp. It can be dealt with by treating the end face in an R shape, but originally a hard and small-sized bristle requires a step of flocking to the base, and if the end face treatment is performed, the cost increases and the product becomes expensive.

  Traditionally, scalp massage brushes have been made for the purpose of striking or rubbing the scalp, and the action of stretching the scalp, such as twisting, can be slightly obtained when a large number of bristles provided on the base move on the scalp. There was no such thing that at least one bristle had an action to stretch the scalp, such as twisting or pushing the scalp.

  The present invention provides a safe scalp massage brush having an excellent massage effect that has an action of stretching the surface of the scalp such as twisting and pushing the bristle other than rubbing the scalp and does not damage the scalp. It is.

  In order to give gentle stimulation without damaging the scalp, the bristle is formed using a flexible material such as elastomer or synthetic rubber. In order to obtain an excellent massage effect, the contact of the bristle to the scalp is made by multipoint contact, and the contacted multipoint is made by a small projection that flexes flexibly, so that contact with only one point of the conventional bristle tip can be obtained. It has the effect of stretching the scalp, such as twisting and spreading. That is, a plurality of small protrusions that flexibly touch the scalp at the tip of the bristle are provided. In detail, it is important that a single bristle is composed of a base portion that occupies a large volume and a small protrusion located at the tip thereof. However, it touches the hair during massage and does not bend easily and does not reach the scalp. Even if it reaches, the length of the small protrusions will increase, so each small protrusion will bend and move uniformly during massage. There is almost no effect of stretching the scalp, such as twisting or spreading the scalp. The base portion serves as a guide for guiding the small protrusions to the scalp, and it is possible to obtain a remarkable effect of stretching the scalp such as twisting by making the length close to the distance width to bend without lengthening the small protrusions. Furthermore, if the length of the small protrusion is too short, flexible bending cannot be obtained, and if it is too long, the action of stretching the scalp, such as rubbing and twisting, is extremely reduced. The average thickness of the protrusions should be at least 2.5 times and at most 7 times at most.

  Preferably, it is simple in shape to form a small protrusion by providing a groove at the tip of the bristle, and it is difficult to entangle the hair without unnecessary steps at the boundary between the bristle and the small protrusion, which is also wasteful in structural strength. It is good because the bristle can be made compact.

  Furthermore, during massage, it is preferable that each small protrusion bends and moves independently, which increases the effect of twisting the scalp, etc., so that when the bristles are pressed against the scalp, the small protrusions open apart from each other. The tip of the small projections that come into contact with each other is inclined, or the thickness of each small projection is not the same, but at least two types are used to change the bending rigidity and change the way it bends. good. In addition, it is possible to change the length of some small protrusions and change the way it bends and get the action to stretch the scalp, but there is no remarkable effect and if the length is greatly different, it will not be massaged with short small protrusions Because it is, it is not highly recommended.

  The scalp massage brush of the present invention has an action of stretching the scalp such as twisting and spreading in addition to the action of a single bristle rubbing the scalp, so it has a gentle and effective massage effect on a small area where the bristle tip contacts. Furthermore, the scalp can be provided with an excellent massage effect with a large number of points in a wide area, that is, with a high density, as many as the number of bristle installed on the base. At the same time, it is possible to provide a scalp massage brush that can be used safely without bristle formed of a flexible material gently stimulating and damaging the scalp.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a scalp massage brush according to a first embodiment of the present invention. FIG. 2 is a perspective view of the bristle of FIG. 3 is a front and side view of the bristle of FIG. 4 is a top view of the bristle of FIG. FIG. 5 is a reference diagram showing a state when the bristle of FIG. 1 is pressed against the scalp. FIG. 6 is a front view of the bristles of Example 2 used for the scalp massage brush of the present invention. FIG. 7 is a top view of the bristle of FIG.

  Referring to FIG. 1, the scalp massage brush of the present invention comprises a bristle 1, a base 2 and a gripping part 3. The bristle 1 is made of a flexible material such as elastomer or rubber so as not to damage the scalp. The grip portion 3 may be made of a material such as synthetic resin or wood. Specifically, the material of the bristle 1 includes, for example, styrene type represented by SBS and SEBS for elastomer, olefin type represented by EPDM, and other thermoplastic resins such as ultra-low molecular weight PE and EVA, and SBR and NBR for synthetic rubber. There are many types such as polybutadiene, IIR, EPR, and silicone rubber. As a guideline, it is preferable to use a material having a flexural modulus of 100 MPa or less and a surface hardness [Shore A] of 70 or less. The bristle 1, the base 2, and the gripping part 3 may be individually molded and assembled. For example, the base 2 and the gripping part 3 are integrally molded and the bristle 1 is press-fitted into a recess provided in the base 2. If the disk-shaped base 2 formed integrally with the bristle 1 with an elastomer is fitted and installed so as to have a cushioning property at the periphery of the grip portion 3 formed in a dish shape, the productivity and It is good because it becomes more excellent in function.

  Referring to FIGS. 2 to 5, a groove 5 is formed in a cross at the tip of the bristle 1 of a substantially quadrangular prism, and four small projections 4 of a substantially quadrangular prism are formed. The corners of the bristle 1 and the small protrusions 4 are provided with at least a small R so as to improve the comb and prevent damage to the hair. The width and depth of the groove 5 are preferably designed in consideration of the length of the small protrusion 4 being 2.5 times to 7 times the average thickness of the small protrusion 4 and the bending rigidity of the material used. The side surface of the bristle 1 is preferable since there is no step except for the groove 5 and the hair is smooth and hardly tangled. In order to promote the action of stretching the scalp such as twisting the scalp, it is preferable that each small protrusion 4 bends in a different direction or changes the degree of bending during massage, so that the tip surface of the small protrusion 4 that contacts the scalp For example, when the bristle 1 is pressed against the scalp, the small protrusions 4 are preferably inclined so as to open apart from each other.

  Referring to FIGS. 6 and 7, one tapered small protrusion 4 having a large diameter and a small diameter is provided at the tip of a tapered elliptical bristle 1 respectively. The action of twisting the scalp can be enhanced by making each small protrusion 4 bend uniquely during massage. Thus, the shape of the bristle 1 and the small protrusion 4 is not particularly limited.
