1. Field of the Invention
The present invention relates generally to an adapter which is intended to apply liquid material. More particularly, the present invention relates to a liquid-material application adapter which is capable of evenly applying liquid material using a dual roller structure, and a liquid-material application apparatus having the adapter.
2. Description of the Related Art
Conventional liquid material is applied to a desired place using the hand or a brush, after being discharged from a container containing the liquid material. During the operation of applying the liquid material, the liquid material may adhere to an undesired place, for example, the hand or clothing.
In order to solve the problem, it was attempted to apply liquid material using one roller. However, in the case of applying the liquid material using only one roller, an excessively large or small amount of liquid material is applied to the roller, so that it is impossible to evenly apply the contents. Particularly when an excessively large amount of liquid material is applied to the roller, the roller swells up, so that it is not easy to rotate the roller.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a liquid-material application adapter with a dual roller structure, which prevents liquid material from being applied to undesired places.

The roller units accommodated in the roller support 100 are disposed above the lower surface of the roller support 100, and comprise the first roller unit 200 which is in contact with the contents discharged from the discharge port 110, and the second roller unit 300 which is placed on a side of the first roller unit 200 to be in contact with the first roller unit 200.
Thus, when the second roller unit 300 rotates while making contact with a surface to which contents are to be applied, the first roller unit 200 rotates while being in contact with the second roller unit 300. When the first and second roller units 200 and 300 rotate, the contents discharged from the discharge port 110 are applied to the first roller unit 200, and then are transferred from the first roller unit 200 to the second roller unit 300.
The first and second roller units 200 and 300 may be made of soft or hard material. However, it is preferable that the second roller unit 300 be made of soft material.
As shown in
The concave part 120 is formed by depressing the lower surface of the roller support 100 down in a concave manner, and has a shape corresponding to that of the first roller unit 200 so that the first roller unit 200 can be received therein.
As shown in
The first roller unit 200 according to the present invention may be formed in various shapes. According to this embodiment, the first roller unit 200 has a cylindrical shape as shown in
Such a first roller unit 200 may be provided with a plurality of grooves 210. The grooves 210 formed on the first roller unit 200 may be oriented in a direction perpendicular to the direction of rotation of the first roller unit 200 as shown in

When the grooves 210 of the first roller unit 200 are formed in a direction which is inclined relative to the direction of rotation of the first roller unit 110, the grooves 210 of the first roller unit 200 may cross each other as shown in
Further, a plurality of protrusions 220 may be formed on the outer surface of the first roller unit 200 according to the present invention, as shown in
The grooves 210 formed on the outer surface of the first roller unit 200 may be formed at various depths and intervals according to embodiments. Further, the protrusions 220 of
Further, the first roller unit 200 may comprise a plurality of balls, in addition to the cylindrical shape.
As shown in
As shown in
When the first and second roller units 200 and 300 are arranged as shown in
Further, as shown in
In this case, one pair of rollers of the first roller unit 200 rotate in the same direction by the roller of the second roller unit 300, thus transmitting contents from the discharge port 110 to the roller of the second roller unit 300.
Here, since the first roller unit 200 includes two rollers, the contents discharged from the discharge port 110 may be transmitted over a larger area of the roller of the second roller unit 300.
Further, as shown in
More preferably, the first and second rollers of the first roller unit 200 are spaced apart from each other, and the first and second rollers of the second roller unit 300 are spaced apart from each other.
In this case, contents discharged from the discharge port 110 are applied to the first and second rollers of the first roller unit 200, respectively, so that the contents may be independently transmitted to the first and second rollers of the second roller unit 300. Thus, even if a surface which is in contact with the second roller unit 300 is not flat, the contents may be evenly applied onto the surface.
Further, as shown in
In this case, after contents discharged from the discharge port 110 are applied to the first roller which is placed above the discharge port 110, the contents are evenly spread out by the second and third rollers of the first roller unit 200. Thereafter, the contents are transmitted to the roller of the second roller unit 300.
Further, as shown in
Preferably, the first roller of the first roller unit 200 is spaced apart from the roller of the second roller unit 300.
In this case, after contents discharged from the discharge port 110 is primarily applied to the first roller of the first roller unit 200 which is placed above the discharge port 110, the contents are evenly transmitted to the second and third rollers which are arranged on opposite sides of the first roller, and thereafter are transmitted to the roller of the second roller unit 300. Thus, the contents may be more evenly spread onto the roller of the second roller unit 300.
Further, as shown in
In this case, first and second rollers of the second roller unit 300 are arranged, respectively, between the first and second rollers of the first roller unit 200 and between the first and third rollers of the first roller unit 200, thus rotating the rollers of the first roller unit 200.
Thus, contents transmitted to the respective rollers of the second roller unit 300 are evenly spread by two rollers of the first roller unit 200.
Preferably, the first and second rollers of the second roller unit 300 are spaced apart from each other.
When the second roller unit according to the present invention includes a plurality of rollers, it is preferable that the respective rollers have the same direction of rotation.
The adapter according to the present invention includes a first roller support 1000, a first roller unit 200, a second roller support 1100, and a second roller unit 300.
Among the components of the adapter, the first and second roller units 200 and 300 have been described above. In order to avoid duplicating the description, the description of the first and second roller units 200 and 300 will be omitted. The first and second roller supports 1000 and 1100 will be described below in detail.
The first roller support 1000 has on its upper surface a discharge port 110 to discharge contents therethrough. A concave part 120 is formed in an upper portion of the first roller support 1000 such that the first roller unit 100 may be placed therein. The discharge port 110 is formed on the concave part 120 to communicate therewith.
The second roller unit 300 is rotatably coupled to the second roller support 1100. A slit 1110 is formed through the upper surface of the second roller support 1100 such that a surface of the first roller unit 200 protrudes through the slit 1110 when the second roller support 1100 is coupled with the first roller support 1000.
The second roller unit 300 is coupled to the second roller support 1100 in such a way as to be put in contact with the first roller unit 100 protruding through the slit 1110.
Thus, when the second roller unit 300 rotates, the first roller unit 200 rotates while being in contact with the second roller unit 300, so that contents are transferred from the discharge port 110 to the second roller unit 300.
Each adapter shown in
Since the roller support 1000, the first roller unit 200, and the second roller unit 300 have been described above, only the container 400 will be described below so as to avoid duplicating the description.
As shown in
The pump 420 is provided in the outlet 410 of the container 400, as shown in
The pump 420 generates a difference in pressure between the inside and outside of the container 400, thus discharging liquid material out of the container 400.
As shown in
Thus, when the liquid-material application adapter moves up and down, the pressurizing part 421 is pressurized by the first roller support 1000 of the liquid-material application adapter, thus discharging liquid material out of the container 400.
Here, as shown in
As for the embodiment shown in
Such a container 400 may hold various liquid materials, for example, liquid cosmetics, such as foundation, BB cream, or suncream, medicines such as a medical ointment, or adhesives.
Further, as shown in
As described above, the present invention provides a liquid-material application adapter with a dual roller structure, which is constructed to apply liquid material using a second roller unit, thus preventing the liquid material from adhering to an undesired place, such as a user's clothing or hands, when the liquid material is applied, and is constructed so that liquid material of the second roller unit is evenly spread out by a first roller unit, thus enabling the liquid material to be evenly applied. Further, the adapter has the dual roller structure, thus preventing the roller from swelling up when the adapter is repeatedly used.
Further, the present invention provides a liquid-material application apparatus having a liquid-material application adapter, which allows contents to be uniformly discharged out of a container using a pump and to be evenly applied.
