Description

Brush {Brush}

The present invention relates to a brush.

In general, brushes are daily necessities that have been closely related to human life since ancient times, such as hairbrushes, clothes brushes, makeup brushes, and toothbrushes, and their types and designs are developing day by day. A comb or hair brush is a tool used to groom, comb, or make washing hair easier.

Moreover, recently, hair brushes that accommodate functional substances, such as ampoules, and transfer ingredients to the hair or scalp have been released and are being widely used in order to use hair brushes as functional tools.

For example, a brush has been developed that has a structure in which an ampoule is placed in a part of the handle or container of a hair brush and the ampoule flows out through a tube inside the brush to the tip of the brush, or a hair brush that functions to massage the scalp by simultaneously pressing a container containing an ampoule by hand and flowing out the liquid through a brush connected to the container.

Meanwhile, in order to allow the effective ingredients of scalp and hair care products to penetrate deep into the scalp and provide nutrition, a method of patting or rubbing the ampoule applied to the scalp with your hands is used.

However, since the ampoule is in a liquid state and can flow down the scalp, there is a limit to sufficiently delivering the effective ingredients of the ampoule to the scalp, and there is the cumbersome problem of having to apply the ampoule to each section of the hair.

The present invention has been created to solve the problems of the prior art as described above, and an object of the present invention is to provide a brush that can effectively apply a functional material in a liquid formulation to the scalp to prevent waste, and also facilitate the delivery of the functional material without the need to divide the hair shaft.

A brush according to one aspect of the present invention comprises: a main body; and an application portion provided on one side of the main body, wherein the application portion has a plurality of protrusions and an electrode portion positioned between the protrusions, wherein at least one of the plurality of protrusions is an uneven protrusion having a recessed structure in which valleys and mountains are repeatedly formed on a surface, and the uneven structure is provided continuously along a longitudinal direction.

Specifically, at least two of the plurality of protrusions may be arranged in a form in which the length gradually increases from one side of the application portion to the other side, so that an imaginary line formed by the ends of the protrusions is inclined with respect to a surface of the application portion.

Specifically, at least one of the protrusions may have a shape in which the cross-section of the tip is smaller than that of the base, and the cross-section may be biased from one side of the application portion toward the other side as it goes from the base to the tip.

Specifically, the protrusion disposed on the other side of the application portion may have a shape with a relatively large cross-section compared to the protrusion disposed on one side of the application portion.

Specifically, the application part may have a flow path structure formed continuously with the uneven structure around the uneven protrusion on the surface where the base of the uneven protrusion is provided.

Specifically, the application part may have a recessed part arranged around the protrusion part on the surface where the base of the protrusion part is provided.

Specifically, the protrusion may be provided with a cooling section at the end made of a material having relatively good heat generation properties compared to the base.

Specifically, the electrode part can provide a galvanic current of 100 to 400 μA.

Specifically, the device may further include a storage unit that stores a functional substance delivered to the body through the application unit.

The brush according to the present invention enables the application of a functional material having a liquid formulation to the scalp to be carried out efficiently and without waste, and also improves the convenience of the user by helping the absorption of the functional material without dividing the hair into sections.

The purpose, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments in conjunction with the accompanying drawings. In this specification, when adding reference numerals to components in each drawing, it should be noted that the same components are given the same numerals as much as possible even if they are shown in different drawings. In addition, in describing the present invention, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

For reference, the application area is described below as limited to the scalp where hair is provided for convenience, but it should be noted that this does not unduly limit the scope of the rights of the present invention. In addition, the functional material described below may be a cosmetic or medical ampoule, or a material for preventing hair loss, etc.

FIG. 1 and FIG. 2 are perspective views of a brush according to a first embodiment of the present invention, FIG. 3 is a side view of a brush according to the first embodiment of the present invention, and FIG. 4 is a bottom view of a brush according to the first embodiment of the present invention.

Also, FIG. 5 is a partial perspective view of a brush according to the first embodiment of the present invention, FIGS. 6 and 7 are exploded perspective views of a brush according to the first embodiment of the present invention, and FIGS. 8 to 10 are usage state diagrams of a brush according to the first embodiment of the present invention.

Referring to FIGS. 1 to 10, a brush (1) according to the first embodiment of the present invention includes a main body (10), an application part (20), an operating part (30), etc.

The main body (10) is configured to include an operating part (30) to be described later, and is provided in a shape that can be grasped by a user. For example, the main body (10) may be provided with a ring (not shown) that allows the user's finger to enter, as shown in the drawing, and the part for the user to grasp may be defined as a grip part (11).

Of course, the main body (10) may be provided with a gripping part (11) of various shapes that allows the user to easily grip the main body (10) instead of or together with the ring. For example, the main body (10) may have a gripping part (11) formed as a separate protruding or penetrating part.

Alternatively, the main body (10) may not have a separate part for gripping, but rather the shape of the main body (10) itself may be designed to facilitate gripping, so that the entire main body (10) may form a gripping part (11). In addition, the main body (10) may be made in a streamlined shape so that the user can conveniently grasp and carry it.

A sensing unit (12) may be provided in the main body (10). The sensing unit (12) is provided in the grip unit (11) of the main body (10), etc., and can detect that the user has gripped the main body (10) and control the electrode unit (22) to be described later.

For example, the sensing unit (12) may be an infrared sensor that detects contact with the user's skin, and is arranged on the inside of the ring of the grip unit (11). When the user's finger touches the sensing unit (12), the sensing unit (12) can sense a current signal and transmit an appropriate signal to the operating unit (30). Alternatively, the sensing unit (12) may be provided in a form that is not limited to various locations on the main body (10) depending on the shape, arrangement, etc. of the grip unit (11).

Alternatively, the sensing unit (12) may be a switch that transmits a signal to the operating unit (30) in response to the user's external force, in addition to a sensor that actively detects the user's contact. In this case, the sensing unit (12) may be configured to control the electrode unit (22) through the operating unit (30) when it detects that a certain amount of external force from the user is input.

In this specification, the term sensing/sensor encompasses all configurations that control the operating unit (30) based on external stimuli in addition to known sensor types. Furthermore, the external stimuli may be not only the touch of the body, but also light, sound, etc.

The application part (20) is provided on one side of the main body part (10). When the user carries the main body part (10) with a hand or the like, the application part (20) comes into contact with the user's body and delivers a functional substance to the scalp.

The method by which the application unit (20) delivers the functional material to the user's scalp is as follows. The user can first prepare a separately prepared ampoule container, open the ampoule container, and deliver the functional material to the application unit (20). Thereafter, the user can hold the main body (10) and apply the application unit (20) containing the functional material to the scalp so that the functional material is effectively delivered to the scalp.

Alternatively, in the present embodiment, a storage unit (not shown) for storing a functional material may be provided within the main body (10) or the application unit (20). In this case, the storage unit may be delivered to the application unit (20) by being discharged through a discharge port or the like that may be provided in the application unit (20).

For example, when a user grasps the main body (10), the functional material stored in the storage unit can be automatically transferred to the application unit (20) by the sensing unit (12). Alternatively, the present embodiment can also use a structure that allows the user to manually implement discharge of the storage unit by using a discharge means such as a pump.

The method of use after the functional material is transferred from the storage unit to the application unit (20) is the same as when the ampoule container was used. That is, the user can hold the main body unit (10) and transfer the functional material to the scalp of the body through the application unit (20).

The application part (20) includes a protrusion part (21), an electrode part (22), and a recessed part (23). The protrusion parts (21) are provided in multiple numbers and may be arranged in an appropriate arrangement on the surface of the application part (20). For example, a plurality of protrusion parts (21) may be arranged at an appropriate interval so that even if the protrusion parts (21) are pressed against the scalp and bent, the protrusion parts (21) may not interfere with each other.

The protrusion (21) may be a configuration that comes into contact with the scalp while the functional material is applied thereto, and the protrusion (21) may have a shape with a small cross-section at the tip compared to the base. That is, the protrusion (21) may have a shape such as a cone or a square pyramid, and the tip of the protrusion (21) has a pointed shape. However, the shape of the tip of the protrusion (21) may vary depending on the degree of stimulation required when applying the functional material.

Since the protrusion (21) has a relatively horn-like shape, in this embodiment, when a functional material is applied to the scalp using the application portion (20), the application portion (20) can automatically divide the hair into sections during the process of sweeping the scalp, thereby bringing about the effect of evenly applying the ampoule to the scalp.

The protrusion (21) may be made of an elastic material such as soft silicone or rubber. Accordingly, when the protrusion (21) comes into contact with the scalp, it is possible to provide a moderate stimulation to the scalp. In other words, the present embodiment uses an elastically deformable protrusion (21) to protect the scalp and at the same time provide a scalp massage effect, and also allows the functional material to be gently applied to the scalp with an appropriate stimulation.

The protrusions (21) of the present embodiment may be arranged in a form in which the length gradually increases from one side of the application portion (20) to the other side. For example, as shown in Fig. 8, the length (L2) of the protrusions (21) arranged on the right side of the application portion (20) is formed to be relatively larger than the length (L1) of the protrusions (21) arranged on the left side of the application portion (20).

In this case, if a virtual surface is formed by using the ends of at least three or more of the protrusions (21) among the plurality of protrusions (21), the virtual surface can be arranged to be inclined with respect to the surface of the application portion (20). At this time, the virtual surface can be a flat surface or a curved surface, and the virtual surface and the surface of the application portion (20) can be inclined clockwise with respect to Fig. 8. Alternatively, the virtual surface can be arranged to be inclined along at least two axes with respect to the surface of the application portion (20).

In addition, the protrusion (21) may have a shape in which the cross-section is gradually deflected from one side of the application portion (20) to the other side as it goes from the base to the end. That is, as shown in FIG. 8, the protrusion (21) may be provided such that the left side is inclined at an angle other than 90 degrees with respect to the surface of the application portion (20), and the right side is inclined at an angle of 90 degrees with respect to the surface of the application portion (20) or closer to 90 degrees with respect to the left side. Accordingly, the protrusion (21) may have a shape of an inclined cone or an inclined polygonal pyramid.

Compared to the protrusion (21) that is arranged on one side of the application portion (20) and has a relatively short length, the protrusion (21) that is arranged on the other side of the application portion (20) and has a relatively long length may have a relatively large cross-section. In other words, the size of the protrusion (21) itself may become larger as it goes from one side of the application portion (20) to the other side of the application portion (20).

At least one of the protrusions (21) may be provided as a rough protrusion (211). The rough protrusion (211) may be provided with a rough structure (211a) in which valleys and mountains are repeatedly formed on the surface. In this case, since the valleys and mountains are continuously provided along the length direction between the base and the end of the rough protrusion (211), the functional material may be induced to flow smoothly along the end of the rough protrusion (211).

That is, the protrusion (21) can be formed by a combination of a protrusion formed to form a smooth surface and an uneven protrusion (211) formed to form an uneven surface. Of course, it is also possible for the entire protrusion (21) to be formed only of an uneven protrusion (211).

The uneven structure (211a) of the uneven protrusion (211) may be a biomimetic surface groove structure. For example, in addition to the straight-line shape of valleys and mountains as shown in the drawing, the uneven structure (211a) may also have a curved shape, such as grooves or wave shapes on the surface of a shell. Through this, the uneven protrusion (211) smoothly delivers functional materials to the scalp while suppressing waste.

Since the uneven projection (211) has a horn shape with a cross-section that becomes smaller from the base to the tip, the uneven structure (211a) also becomes smaller in size from the base to the tip. In this case, the uneven projection (211) can utilize capillary action to cause functional materials to gather at the tip of the uneven projection (211).

In this embodiment, the uneven protrusions (211) can be placed in the central portion of the application portion (20). This allows the functional material to gather in the central portion of the application area of the application portion (20), thereby effectively allowing the functional material to be absorbed into the scalp.

That is, the uneven protrusion (211) has a uneven structure (211a) as compared to other protrusions, and thus is capable of carrying a functional material, and can increase the transmission power to the scalp by gathering the functional material to the end.

Referring to FIG. 5, etc., in order to guide a functional material to the uneven structure (211a) of the uneven projection (211), a channel structure (24) may be provided on the surface of the application portion (20). The channel structure (24) is formed around the uneven projection (211) on the surface of the application portion (20) where the base of the uneven projection (211) is provided, and may be continuously connected to the uneven structure (211a).

As described above, since the uneven structure (211a) is continuously provided along the longitudinal direction on the surface of the uneven protrusion (211), the uneven structure (211a) can have an open form at the base of the uneven protrusion (211). At this time, the open portion of the uneven structure (211a) can be continuous with the flow path structure (24) connected to the base of the uneven protrusion (211), and through this, the functional material transferred to the surface of the application portion (20), etc., can flow more effectively toward the end of the uneven protrusion (211).

The flow path structure (24) may be formed radially based on the center of the protrusion (211), or the protrusion (211) may be formed in a form that is biased toward one side of the application portion (20) compared to the other side, so that the flow path structure (24) may be formed in a spiral direction rather than a radial direction. In other words, the flow path structure (24) may have a form that extends between the tangential direction of the base circumference of the protrusion (211) and the center direction of the protrusion (211).

Of course, the flow path structure (24) may have a shape dependent on the direction, shape, size, number, etc. of the uneven structure (211a) provided on the uneven projection (211). In addition, the flow path structure (24) may be provided at a location that does not interfere with the recessed portion (23) described later, and in this case, the flow path structure (24) may be formed only on a part of the base circumference of the uneven projection (211).

The surface of the protrusion (21) including such uneven protrusions (211) can contain a functional material having a certain viscosity, and in particular, the functional material can be supported on the surface of the protrusion (21) by surface tension (ampoule capturing).

At this time, when the protrusion (21) touches and presses the scalp, the functional material that was supported on the surface of the protrusion (21) by surface tension can be applied to the scalp by physical force (N). In addition, at the same time, the user's hair can be divided into sections through the protrusion (21), and the functional material can be evenly applied to the scalp.

Below, a description is given of a state in which the application portion (20) equipped with the above-mentioned protrusion (21), etc., is used on the scalp. First, a functional material may be delivered to the application portion (20) through the above-mentioned method.

As shown in FIGS. 8 and 9, the grip portion (11) of the main body (10) can be positioned to one side of the application portion (20), so that the user's finger can be positioned to one side of the application portion (20), and the user's palm can be positioned to the other side of the application portion (20).

At this time, since the length (L1) of the protrusion (21) on one side of the application portion (20) is formed relatively short, the user's fingertips can touch the scalp. Accordingly, the user can sense by touch whether the functional material is actually properly applied to the scalp and whether the amount applied is appropriate by touching the scalp with the fingertips.

Accordingly, the user can perform application while controlling the amount of the functional material. Through this function, the present embodiment allows the user to smoothly check the fine degree of application amount of the functional material through the tactile sense of the fingers, which is more developed than the scalp.

On the other hand, the length (L2) of the protrusion (21) on the other side of the application portion (20) can be manufactured to be the same as the user's standard head height and can be made the same as the average length of the user's hair.

That is, in this embodiment, by forming the lengths of the protrusions (21) on one side of the application portion (20) and the protrusions (21) on the other side of the application portion (20) differently, when the user combs the scalp and hair roots with the protrusions (21), the fingers and the protrusions (21) can simultaneously touch the hair roots, thereby preventing hair loss or hair tangling and waste of functional materials.

For example, referring to Fig. 9, the protrusion (21) is gradually formed longer from one side of the application part (20) to the other side, thereby facilitating combing along the user's convex back of the head. In addition, depending on the implementation, the user may hold the main body part (10) in the opposite direction to suit his or her head shape.

Furthermore, the present embodiment can provide massage stimulation (physical stimulation) by utilizing this structure, thereby obtaining additional effects such as improved blood flow to the scalp, increased elasticity, and promotion of absorption of effective ingredients of functional materials. These effects can be further enhanced by galvanic stimulation (electrical stimulation) of the electrode portion (22) described below.

The electrode part (22) is provided on the surface of the application part (20) and can be positioned between the protrusions (21). The electrode part (22) has an electrode rod shape and can have a similar height to the protrusions (21). Therefore, when the protrusions (21) come into contact with the scalp, the electrode part (22) can also come into contact with the scalp.

Unlike the protrusion (21), the electrode portion (22) may extend perpendicularly to the surface of the application portion (20), and at least two or more may be provided to form a closed electrical circuit between the scalp and the application portion (20).

The electrode part (22) can be adopted as a material that implements a galvanic function, and can be equipped with a material (for example, a metal material) that has fast thermal conductivity, high durability, and does not cause an allergic reaction when in contact with the user's skin.

The electrode part (22) may be connected to the operating part (30) described later to generate a microcurrent, and may provide, for example, a galvanic current of 100 to 400 μA. Accordingly, the electrode part (22) may send a current to the user's scalp to promote absorption of a functional material through galvanic electrical repulsion.

In addition, the electrode part (22) may be configured by adding powder of quartz, germanium powder, anion powder, etc. so that it can radiate far infrared rays, negative ions, etc. In addition, the electrode part (22) may implement various additional functions that are not limited to assist in the absorption of functional materials.

The recessed portion (23) is provided on the surface of the application portion (20). The recessed portion (23) is provided in a sunken form on the surface of the application portion (20) and can store a functional material. The recessed portion (23) is provided around the protrusion (21) on the surface of the application portion (20) where the base of the protrusion (21) is provided, so that the functional material can be temporarily stored on the surface of the application portion (20) and then transferred toward the protrusion (21).

The recessed portion (23) may have a shape in which a plurality of grooves are formed to form a pattern on the surface of the application portion (20). At this time, the grooves may be formed in a circular or polygonal shape (preferably hexagonal) shape to increase the temporary storage efficiency of the functional material, and the grooves may be spaced apart from each other. For example, as shown in the drawing, the recessed portion (23) may be formed in a honeycomb shape.

The recessed portion (23) may overlap at least partly with the protrusion portion (21). Of course, the arrangement of the protrusion portion (21) and the shape (arrangement of the groove) of the recessed portion (23) may be linked, but as shown in the drawing, in this embodiment, the base of the protrusion portion (21) is positioned in one of the grooves of the recessed portion (23), so that the groove and the protrusion portion (21) overlap each other.

When only a part of the base of the protrusion (21) is placed within the groove, the functional material stored in the groove can be delivered through a part of the circumference of the base of the protrusion (21). However, since the protrusion (21) has a small horn shape in the cross section of the end compared to the base, the functional material can be smoothly delivered to the end of the protrusion (21) despite the arrangement of the groove as described above.

The operating unit (30) operates the electrode unit (22). The operating unit (30) may be placed inside the main body (10) and may be composed of electrical components including a battery, a circuit board, etc. In addition, the operating unit (30) may be provided with various components (e.g., a converter and a controller) for providing galvanic current to the electrode unit (22) as needed.

The operating part (30) may be provided as an external rechargeable unit. In this case, the battery of the operating part (30) can store power supplied through an external charging port. Of course, the main body (10) and the application part (20) are separated so that the operating part (30) can be exposed to the outside, and the battery, etc. can be replaced.

Referring to Fig. 6, the operating unit (30) may be equipped with a vibration motor. The vibration motor may provide additional physical stimulation to the scalp in addition to the massage stimulation of the protrusion (21). Therefore, the present embodiment may increase the absorption rate of the functional material by using two types of physical stimulation and one type of electrical stimulation.

Of course, considering the portability/use convenience according to weight, the operating time of the operating part (30), the size optimized for the grip, etc., the operating part (30) may not be equipped with a vibration motor as in Fig. 7.

In this way, the present embodiment enables massage with appropriate physical stimulation through the protrusion (21) provided on the application portion (20), thereby increasing the blood flow to the scalp hair follicles and dermal layer and helping absorption of the effective ingredients of the functional material.

In addition, this embodiment enables the user to recognize whether the formulation of the functional material applied to the scalp is appropriate by the touch of the finger through the unique shape and arrangement of the protrusion (21), thereby enabling proper use of the functional material.

In addition, this embodiment can help to supply the functional material to the maximum with a minimum amount by efficiently delivering the functional material applied to the application portion (20) to the scalp through the protrusion portion (21). Furthermore, this embodiment utilizes a galvanic electrode to promote effective absorption of the active ingredient of the functional material and realize the effect of scalp elasticity.

Figures 11 and 12 are perspective views of a brush according to a second embodiment of the present invention.

In the following, the differences between this embodiment and the previous embodiment will be mainly explained, and any omitted parts will be replaced with the previous contents.

Referring to FIGS. 11 and 12, the brush (1) according to the second embodiment of the present invention may have a cooling section (212) on the protrusion (21).

As described above, the protrusion (21) has a massage function, and in addition, the protrusion (21) of the present embodiment has a cooling section (212) made of a material having relatively good heat generation properties compared to the base section at the end.

For example, the cooling unit (212) may be made of a metal material (e.g., ZAMAC) and may implement cooling for a functional material. In addition, the functional material may contain moisture, and the cooling unit (212) may maximize the cooling sensation for the functional material when it meets the moisture formulation.

The cooling unit (212) may have a water drop shape, as shown in the drawing. That is, the protrusion (21) of the previous embodiment has a horn shape, but in the present embodiment, as the cooling unit (212) is applied to the protrusion (21), the protrusion (21) is provided in the shape of a horn with a water drop attached to it.

Through this, the present embodiment can ensure that the functional material is sufficiently cooled when it moves from the base to the end along the surface of the protrusion (21) and meets the surface of the relatively expanded cooling section (212).

Alternatively, the cooling unit (212) may be formed in the shape of a small spoon, and can effectively generate heat for the functional material while sufficiently containing the functional material in the affected area.

For reference, unlike in Fig. 11, in this embodiment as well, as in the previous embodiment, at least a portion of the protrusions (21) may be formed as uneven protrusions (211).

In this way, the present embodiment enables a cooling sensation stimulation massage by applying a cooling end (212) to the end of the protrusion (21), thereby further enhancing the moisture and cooling sensation when using a functional material in a water formulation.

That is, as described in the previous embodiment, this embodiment helps to increase the blood flow of the scalp hair follicles and dermis layer by massaging with appropriate physical stimulation, and at the same time, the moisture (and menthol component) of the functional substance and the cooling group (212) work together to provide a cooling sensation to the scalp epidermis layer.

Figure 13 is a perspective view of a brush according to a third embodiment of the present invention.

Referring to FIG. 13, the brush (1) according to the third embodiment of the present invention may have a recessed portion (23) partially provided on the surface of the application portion (20) as compared to the first embodiment.

The depression (23) can be formed particularly intensively in the area where the protrusions (211) are provided, and the functional material is absorbed and then delivered to the scalp through the protrusions (21) as in the first embodiment.

However, in this embodiment, the size of the recessed portion (23) on the surface of the application portion (20) can be reduced, thereby reducing the amount of the functional material that the application portion (20) absorbs. On the other hand, in this embodiment, when a user provides a functional material to the application portion (20), the transfer power for the functional material provided outside of the recessed portion (23) may be somewhat lower than in the first embodiment.

In consideration of this, the present embodiment may be advantageous when the amount of functional material used is less than that of the first embodiment and/or when the surface tension or viscosity of the functional material is higher than that of the first embodiment.

FIG. 14 is a perspective view of a brush according to a fourth embodiment of the present invention, FIG. 15 is a bottom view of a brush according to a fourth embodiment of the present invention, and FIG. 16 is a side view of a brush according to a fourth embodiment of the present invention.

Referring to FIGS. 14 to 16, the brush (1) according to the fourth embodiment of the present invention may not have a recessed portion (23) provided in the application portion (20). In the previous embodiment, the recessed portion (23) was provided to perform the function of storing the functional material, but in contrast, in the present embodiment, the recessed portion (23) may be minimized or omitted in preparation for cases where a high viscosity functional material is used, for which there is a risk of the functional material remaining in the recessed portion (23).

In addition, in this embodiment, most of the protrusions (21) provided on the application portion (20) can be provided as uneven protrusions (211). In the previous embodiment, the uneven protrusions (211) were applied mainly to the central portion of the application portion (20) to deliver the functional material through the central portion of the application portion (20), but in this embodiment, the distribution area of the uneven protrusions (211) can be expanded so that the functional material can be delivered efficiently by utilizing the entire application portion (20).

That is, in the present embodiment, the protrusions (21) provided on the application portion (20) are mainly formed of uneven protrusions (211), and only a portion of the protrusions (21) surrounding the protrusions may be formed in a form other than uneven protrusions (211). Of course, it is also possible for the protrusions (21) to be formed entirely of uneven protrusions (211).

The surface of the application portion (20) may be provided with the previously described flow path structure (24), and the flow path structure (24) may be assigned to each uneven projection (211). In this case, the flow path structures (24) assigned to adjacent uneven projections (211) are provided independently of each other, so that the functional material can be sufficiently delivered to each uneven projection (211).

As can be seen in Fig. 15, which shows the side view of this embodiment, the protrusions (21) may have a form in which the height gradually changes from one side of the application portion (20) to the other side. In particular, by arranging the virtual surface connecting the ends of the protrusions (211) for applying the functional material to be inclined with the surface of the application portion (20), the application efficiency of the functional material can be increased.

However, unlike the drawing, the present invention can be such that some (at least two or more) of the plurality of protrusions (21) have the above-mentioned shape, so that the imaginary line connecting the ends of the two or more protrusions (21) can be arranged to be inclined with respect to the surface of the application portion (20), and the remaining protrusions (21) can also be arranged to have a relatively constant height. In addition, the present invention can also be such that only some of the protrusions (21) have a partially biased cross-section.

For example, the present invention is configured such that the height of the uneven projection (211) that is mainly responsible for delivering a functional material and is arranged in the central portion of the surface of the application portion (20) changes from one side of the application portion (20) to the other side and also has a biased cross-section, and the projection (21) arranged around the uneven projection (211) can have a relatively constant height and an unbiased cross-section in the shape of a general cone.

The present invention is not limited to the above embodiments, and may include combinations of the embodiments and combinations of at least one embodiment and known techniques as additional embodiments.

Although the present invention has been described in detail through specific examples, this is intended to specifically explain the present invention, and the present invention is not limited thereto, and it will be apparent that modifications or improvements can be made by those skilled in the art within the technical spirit of the present invention.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be made clear by the appended claims.
