본 발명의 티백(1)의 특징을 이루는 수팽창물질(10)의 구조와 원리에 대하여 설명한다. 대표적으로 섬유를 수팽창물질(10)로 예시하여 설명하지만, 그 재질은 반드시 섬유로 한정되는 것은 아님을 유의해야 할 것이다. The structure and principle of the water-expandable material 10 constituting the characteristics of the tea bag 1 of the present invention will be described. Representatively, fibers are exemplified and described as the water-expandable material 10, but it should be noted that the material is not necessarily limited to fibers.

본 발명의 목적 및 효과, 그리고 그것들을 달성하기 위한 기술적 구성들은 첨부되는 도면과 함께 상세하게 뒤에 설명되는 실시예들을 참조하면 명확해질 것이다. 본 발명을 설명함에 있어서 공지 기능 또는 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐를 수 있다고 판단되는 경우에는 그 상세한 설명을 생략할 것이다.Objects and effects of the present invention, and technical configurations for achieving them will become clear with reference to embodiments described later in detail in conjunction with the accompanying drawings. In the description of the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily flow the gist of the present invention, the detailed description will be omitted.

명세서 전체에서, 어떤 부분이 어떤 구성요소를 "포함"한다고 할 때, 이는 특별히 반대되는 기재가 없는 한 다른 구성요소를 제외하는 것이 아니라 다른 구성요소를 더 포함할 수 있는 것을 의미한다. 한편, 본 발명의 실시예에 있어서, 각 구성요소들, 기능 블록들 또는 수단들은 하나 또는 그 이상의 하부 구성 요소로 구성될 수 있다.Throughout the specification, when a certain component is said to "include", it means that it may further include other components without excluding other components unless otherwise stated. Meanwhile, in an embodiment of the present invention, each component, functional block or means may be composed of one or more sub-components.

도 1a는 최초 길이(Lo)와 최초 두께(Do)를 갖는 섬유의 일부분을 나타낸 것이다. 1A shows a portion of a fiber having an initial length (Lo) and an initial thickness (Do).

섬유의 길이 방향 팽창률을 α로 하면, 일정 시간(t)경과 후의 섬유의 길이(L)는If the expansion rate of the fiber in the longitudinal direction is α, the length (L) of the fiber after a certain time (t) has elapsed is

L = LO(1 + αΔt)이다. (α > 0)L = L O (1 + αΔt). (α > 0)

섬유의 길이는 시간외 온도가 중요한 변수로 작용하지만, 길이와 두께 변화에 모두 영향을 미치는 공평한 인자임을 고려하고, 여기서는 제외하였다.Although the temperature over time acts as an important variable for the length of the fiber, considering that it is a fair factor that affects both length and thickness change, it is excluded here.

다음, 섬유의 두께 방향 팽창률을 β로 하면, 일정 시간(t)경과 후의 섬유의 두께(D)는Next, if the expansion rate of the fiber in the thickness direction is β, the thickness (D) of the fiber after a certain time (t) has elapsed is

D = DO(1 + βΔt)이다. (β > 0)D = DO (1 + βΔt). (β > 0)

여기서, 만약 길이 방향 팽창률 α과 두께 방향 팽창률 β이 동일하다면, 길이와 두께의 변화량은 같다. 그러나, 두께 방향 팽창률 β가 길이 방향 팽창률 α보다 큰 경우에는, 도 1b에 도시한 것과 같이, 섬유는 두께 방향으로 많이 팽창하며, 길이 방향으로는 적게 팽창하거나 팽창 길이가 매우 작게 된다.Here, if the expansion rate α in the longitudinal direction and the expansion rate β in the thickness direction are the same, the amount of change in length and thickness is the same. However, when the expansion coefficient in the thickness direction β is greater than the expansion coefficient in the longitudinal direction α, as shown in FIG. 1B, the fiber expands a lot in the thickness direction and expands little in the longitudinal direction or has a very small expansion length.

도 2는 도 1의 원리를, α = β인 경우와 β > α인 경우 각각에 있어서, 날실과 씨실로 짜여진 직물이 물에 노출된 경우의 팽창 과정을 도시한 것이다.Figure 2 shows the principle of Figure 1, in the case of α = β and the case of β > α, respectively, showing the expansion process when a fabric woven with warp and weft yarns is exposed to water.

도시한 것과 같이 물이 없는 초기 상태에서 직물은 도 2a의 상태이다. As shown, in the initial state without water, the fabric is in the state of FIG. 2a.

α = β인 경우 직물이 물에 노출되면 섬유의 길이와 두께가 같은 비율로 팽창하며(도 2b), 따라서 섬유 사이의 공동의 넓이(그리드의 단면적)가 커져 물의 입출이 자연스럽게 유지된다(도 2c).When α = β, when the fabric is exposed to water, the length and thickness of the fibers expand at the same rate (Fig. 2b), so the width of the cavity between the fibers (the cross-sectional area of the grid) increases, so that the inflow and outflow of water is maintained naturally (Fig. 2c). ).

그런데, β > α인 경우 직물이 물에 노출되면 섬유의 두께가 길이보다 더 팽창하며(도 2d) , 따라서 네 개의 섬유가 형성하는 공동의 넓이(그리드의 단면적)가 사방에서 팽창하는 두께에 의하여 좁혀져 물의 흐름이 둔화되거나 차단된다(도 2e).However, when β > α, when the fabric is exposed to water, the thickness of the fiber expands more than the length (Fig. 2d), so the width of the cavity (cross-sectional area of the grid) formed by the four fibers is increased by the thickness expanding from all sides. Narrowing slows or blocks the flow of water (Fig. 2e).

따라서, 본 발명의 수팽창물질(10)의 제1조건은 일정 시간 경과 후 두께 방향의 팽창률이 길이 방향의 팽창률보다 큰 재료(섬유)이어야 한다는 점이다. Therefore, the first condition of the water-expandable material 10 of the present invention is that the material (fiber) has an expansion rate in the thickness direction greater than that in the longitudinal direction after a certain period of time has elapsed.

다음, 이상과 동일한 원리를 수축률의 관점에서 설명하기로 한다.Next, the same principle as above will be explained in terms of the shrinkage rate.

도 3a는 최초 길이(Lo)와 최초 두께(Do)를 갖는 섬유의 일부분을 나타낸 것이다. Figure 3a shows a portion of a fiber having an initial length (Lo) and an initial thickness (Do).

도 3a에서, 섬유의 길이 방향 수축률을 α'로 하면, 일정 시간(t)경과 후의 섬유의 길이(L)는In FIG. 3A, when the longitudinal shrinkage of the fiber is α', the length (L) of the fiber after a certain time (t) has elapsed is

L = LO(1 + α'Δt)이다. (α' < 0)L = L O (1 + α'Δt). (α'< 0)

다음, 섬유의 두께 방향 수축률을 β'로 하면, 일정 시간(t)경과 후의 섬유의 두께(D)는Next, if the contraction rate in the thickness direction of the fiber is β', the thickness (D) of the fiber after a certain time (t) has elapsed is

D = DO(1 + β'Δt)이다. (β' < 0)D = DO (1 + β'Δt). (β'< 0)

여기서, 만약 길이 방향 수축률 α'과 두께 방향 수축률 β'이 동일하다면, 길이와 두께의 변화량은 같다. 그러나, 길이 방향 수축률 α'이 두께 방향 수축률 β'보다 큰 경우에는, 도 3b에 도시한 것과 같이, 섬유는 길이 방향으로 많이 수축되며, 두께 방향으로는 적게 수축하거나 수축 길이가 매우 작게 된다.Here, if the shrinkage in the longitudinal direction α' and the shrinkage in the thickness direction β' are the same, the amount of change in length and thickness is the same. However, when the longitudinal shrinkage α' is greater than the thickness direction shrinkage β', as shown in FIG. 3B, the fiber shrinks greatly in the longitudinal direction and shrinks little in the thickness direction or the shrinkage length is very small.

도 4는 도 3의 원리를, α' = β'인 경우와 ㅣα'ㅣ >ㅣβ'ㅣ인 경우 각각에 있어서, 날실과 씨실로 짜여진 직물이 물에 노출된 경우의 수축 과정을 도시한 것이다.Figure 4 shows the principle of Figure 3, in the case of α' = β' and in the case of Iα'I > Iβ'I, respectively, showing the shrinkage process when the fabric woven with the warp and weft is exposed to water. will be.

도시한 것과 같이 물이 없을 때 직물은 도 4a의 상태이다. As shown, in the absence of water, the fabric is in the state of FIG. 4a.

α' = β'인 경우 직물이 물에 노출되면 섬유의 길이와 두께가 같은 비율로 수축하며(도 4b), 따라서 전체 면적에 대한 섬유 사이의 공동의 넓이가 변화가 없어 물의 입출이 자연스럽게 유지된다(도 4c).When α' = β', when the fabric is exposed to water, the length and thickness of the fibers contract at the same rate (Fig. (Fig. 4c).

그런데, 경우와 ㅣα'ㅣ >ㅣβ'ㅣ인 경우 직물이 물에 노출되면 섬유의 길이가 두께보다 더 수축하며(도 4d) , 따라서 네 개의 섬유가 형성하는 공동의 넓이가 사방에서 수축하는 길이에 의하여 좁혀져 물의 흐름이 둔화되거나 차단된다(도 4e).However, when the fabric is exposed to water, the length of the fiber shrinks more than the thickness (Fig. 4d), and therefore, the width of the cavity formed by the four fibers shrinks in all directions when the fabric is exposed to water. Narrowed by the length, the flow of water is slowed or blocked (Fig. 4e).

따라서, 본 발명의 수팽창물질(10)의 대체 가능한 다른 조건은 일정 시간 경과 후 길이 방향의 수축률이 두께 방향의 수축률보다 큰 재료(섬유)이어야 한다는 점이다. Therefore, another condition that can be replaced with the water-expandable material 10 of the present invention is that the material (fiber) must have a shrinkage rate in the longitudinal direction greater than that in the thickness direction after a certain period of time has elapsed.

이상의 내용을 종합하면, 본 발명의 티백(1)을 이루는 수팽창물질(10)은 제1방향의 팽창률이 제1방향과 수직인 제2방향의 팽창률보다 크거나 또는 제2방향의 수축률이 제2방향과 수직인 제1방향의 수축률보다 큰 조건을 만족해야 함을 알 수 있다.In summary, the water-expandable material 10 constituting the tea bag 1 of the present invention has an expansion rate in the first direction greater than an expansion rate in the second direction perpendicular to the first direction, or a shrinkage rate in the second direction It can be seen that a condition greater than the shrinkage rate in the first direction perpendicular to the second direction must be satisfied.

이상의 설명을 토대로 본 발명의 수팽창물질(10)을 포함하는 티백(1)의 실시예를 도 5를 참조로 설명한다.Based on the above description, an embodiment of the tea bag 1 containing the water-expandable material 10 of the present invention will be described with reference to FIG. 5 .

이 실시예에서는 티백(1)의 수팽창물질(10)이 가로와 세로로 엮이거나 짜여져 바로 티백(1)을 형성하는 것을 도시하였다. 세로(두께) 방향의 팽창률이 가로(길이) 방향의 팽창률보다 크면 소정 시간 경과 후 도 2에 도시한 것과 같이 물의 흐름이 둔화되거나 차단되어 원하지 않는 티 성분이 물에 용해되거나 분산되지 않으며 따라서 티 본연의 맛을 유지할 수 있다. 수팽창물질(10)의 팽창은 물에 접촉하는 순간 급격히 발생해서는 안되며, 먼저 티 재료가 물에 충분히 녹는 시간을 확보해야 한다. 즉, 가로와 세로 섬유가 형성하는 격자 공간은 시간의 경과에 따라 점점 좁아지며 임계 면적 이하가 되면 물 분자의 흐름을 차단, 억제 또는 둔화시키도록 제작한다. 이러한 점을 충분히 고려하여 가로 및 세로 방향 팽창률과, 두 팽창률의 차이값 및 소정 시간, 즉 물과의 접촉 시간이 적절히 결정된다.In this embodiment, it is shown that the water-expandable material 10 of the tea bag 1 is woven or woven horizontally and vertically to form the tea bag 1 directly. If the expansion rate in the vertical (thickness) direction is greater than the expansion rate in the transverse (length) direction, the flow of water is slowed or blocked as shown in FIG. can retain the taste of Expansion of the water-expandable material 10 should not occur rapidly at the moment of contact with water, and first, sufficient time for the tee material to dissolve in water should be secured. That is, the lattice space formed by horizontal and vertical fibers gradually narrows over time, and when it reaches a critical area or less, the flow of water molecules is blocked, suppressed, or slowed down. In consideration of this point, the horizontal and longitudinal expansion rates, the difference between the two expansion rates, and a predetermined time, that is, the contact time with water are appropriately determined.

가로(길이) 방향의 수축률이 세로(두께) 방향의 수축률보다 큰 경우에도 위와 같은 효과를 발휘하며, 이는 당업자에게 자명한 사항이므로 상세한 설명은 생략한다.Even when the shrinkage rate in the transverse (length) direction is greater than the shrinkage rate in the longitudinal (thickness) direction, the above effect is exhibited, and since this is obvious to those skilled in the art, a detailed description thereof will be omitted.

다음에. 본 발명의 다른 실시예로서 수팽창물질(10)을 포함하는 티백(1)의 다른 구조를 도 6을 참조로 설명한다. next time. As another embodiment of the present invention, another structure of the tea bag 1 containing the water-expandable material 10 will be described with reference to FIG. 6.

도 6에서 티백(1)은 복수의 격자형의 구획부(20)와 각각의 구획부(20)에 시트 형상으로 짜여져 형성된 수팽창물질(10)로 이루어지는 복합구조이다.In FIG. 6, the tea bag 1 has a composite structure composed of a plurality of lattice-shaped compartments 20 and a water-expandable material 10 formed by weaving each compartment 20 in a sheet shape.

구획부(20)는 각각이 가로 방향으로 선을 이루어 전체적으로 평행하게 연장되며 각각이 세로 방향으로 소정 간격을 두고 형성된 가로열(22)과, 각각이 세로 방향으로 선을 이루어 전체적으로 평행하게 연장되며 각각이 가로 방향으로 소정 간격을 두고 형성된 세로열(24)로 이루어진다. 구획부(20)는 티백(1)의 전체에 걸쳐 다수 형성되며, 각각의 구획부(20)는 예를 들어 사각 그리드 형상의 공간(A)을 제공한다. 본 발명의 구획부(20)는 팽창률과 수축률이 매우 작은 소재로 제작되며, 따라서 물과의 접촉에 불구하고 그 형상과 구조는 거의 변하지 않고 부피가 늘어나지 않으며, 공간(A)의 크기는 일정하다. 구획부(20)는 섬유 재질 또는 인체에 무해한 청정 플라스틱 재질로 제작될 수 있다.The partitions 20 each form a line in the horizontal direction and extend in parallel as a whole, and each of the horizontal rows 22 formed at predetermined intervals in the vertical direction, each forming a line in the vertical direction and extending in parallel as a whole, respectively It consists of vertical rows 24 formed at predetermined intervals in the horizontal direction. A plurality of compartments 20 are formed throughout the tea bag 1, and each compartment 20 provides, for example, a square grid-shaped space A. The compartment 20 of the present invention is made of a material with a very low expansion rate and contraction rate, so its shape and structure hardly change despite contact with water, its volume does not increase, and the size of the space A is constant . The compartment 20 may be made of a fiber material or a clean plastic material harmless to the human body.

본 발명의 수팽창물질(10)은 구획부(20)가 제공하는 공간(A)에 시트형으로 스티칭될 수 있다. 또는, 구획부(20) 마다 물이 통과하는 주머니를 형성하고 이 주머니안에 수팽창물질(10)을 충전할 수 있다.The water-expandable material 10 of the present invention may be stitched in the form of a sheet in the space A provided by the compartment 20 . Alternatively, a bag through which water passes may be formed for each compartment 20 and the water-expandable material 10 may be filled in the bag.

수팽창물질(10)은 확대도에 도시한 것과 같이 물과 접촉하면 팽창하는 다수의 섬유소(10A)로 이루어진다. 섬유소(10A)들은 물과 접촉하면 부피가 증가하여 크기가 커진다. 섬유소(10A)들이 물과 접촉하면, 이들, 즉 수팽창물질(10)은 팽창하지만, 구획부(20)의 골격과 형상은 변하지 않으므로 인접한 구획부(20)를 넘어서는 팽창하지 못하며, 따라서 정해진 구획부(20) 내부에서 각각 팽창되어 섬유들간의 간격이 좁아지게 되며, 물의 흐름을 방해하게 된다.As shown in the enlarged view, the water-expandable material 10 is composed of a plurality of fibers 10A that expand upon contact with water. When the fibers 10A come in contact with water, their volume increases and their size increases. When the fibers 10A come into contact with water, they expand, i.e., the water-swellable material 10, but do not expand beyond adjacent compartments 20 because the skeleton and shape of the compartment 20 do not change, and therefore do not expand beyond the defined compartment. Each expands inside the part 20, narrowing the gap between the fibers, and obstructing the flow of water.

섬유소(10A)는 예를 들어 물과 접촉하면 부피가 커지는 한천과 같은 기능을 하며, 팽창 방향은 임의로 하여도 좋다. 하지만, 도 1 내지 도 5를 참조로 설명한 것과 같이 구획부(20)의 공간을 팽창률 또는 수축률이 상이한 재료를 가로와 세로로 엮어 스티칭하여도 동일한 효과를 기대할 수 있음은 물론이다.The cellulose 10A functions like, for example, agar that becomes bulky when in contact with water, and the expansion direction may be arbitrary. However, as described with reference to FIGS. 1 to 5 , the same effect can be expected even if materials having different expansion rates or contraction rates are woven horizontally and vertically and stitched in the space of the compartment 20 .

도 7은 본 발명의 다른 실시예로, 인공 또는 천연 물질의 필름, 또는 시트에서 펀칭이나 기타의 방법으로 외력에 의해 물질을 소형 변형을 시키고, 이때 변형부의 물리적 또는 화학적 변형이 유지된 상태에서 물에 젖거나 특정 온도 이상에서 원래의 상태로 복원되는 원리를 설명하기 위한 도면이다. 이는 일종의 형상기억효과와 유사하다.7 is another embodiment of the present invention, in which a film or sheet of artificial or natural material is deformed in a small size by an external force by punching or other methods, and at this time, the water It is a drawing to explain the principle of restoration to the original state when wet or above a certain temperature. This is similar to a kind of shape memory effect.

종이나 천연 섬유 물질은 팽윤 수축 현상이 있으며, 외력에 의해 영구 변형된 상태가 물속에서 소성 전 상태로 복원되는 성질이 있다. 시트는 실이나 섬유소의 집합체를 포함하며, 직물이나 종이로 구현될 수 있다. 소성 변형은 시트에서 찢어져 분리된 것 외, 직물의 구성 요소인 섬유 또는 섬유소의 소성 변형을 포함한다.Paper or natural fiber material has swelling and contraction, and has a property of restoring a state permanently deformed by an external force to a state before firing in water. The sheet includes a collection of yarns or fibers, and may be embodied in fabric or paper. Plastic deformation includes plastic deformation of fibers or fibres, which are components of a fabric, other than tearing and separation from a sheet.

도 7에서와 같이 수팽창물질(10)은 제1층(A1), 제2층(B1) 및 제3층(C1)의 다층 구조이며 소성변형률은 제1층 > 제2층 > 제3층이고, 수팽창물질(10)은 외부의 힘에 의하여 변형된 상태이다. 수팽창물질(10)이 물에 노출되어 소정 이상의 온도가 되면 원래의 위치로 복원되며 따라서 물 통로가 닫히고 물의 통과가 억제된다. 더하여 도7에서 제1층(A1), 제2층(B1) 및 제3층(C1)은 실제로 상이한 물질이거나 그렇지 않고 단일 물질이지만 소성 변형 과정에서 물성이 변한 경우도 포함될 것이다.As shown in FIG. 7, the water-expandable material 10 has a multilayer structure of a first layer (A1), a second layer (B1), and a third layer (C1), and the plastic strain is the first layer > the second layer > the third layer. And, the water-expandable material 10 is in a deformed state by an external force. When the water-expandable material 10 is exposed to water and reaches a temperature higher than a predetermined level, it is restored to its original position, and thus the water passage is closed and the passage of water is suppressed. In addition, in FIG. 7, the first layer (A1), the second layer (B1), and the third layer (C1) may be actually different materials or a single material, but a case in which physical properties are changed during plastic deformation will be included.

직물에서 일정 길이를 갖는 섬유가 외력에 의해 소성 변형된 상태로 있는 경우 섬유의 말단 부분은 도 7처럼 끝이 돌출되어 있을 수 있으며, 이때, 물에 노출되거나 특정 온도에서, 소성 전의 상태로 복원되어 물의 이동을 억제하게 되는 것이다.When a fiber having a certain length in a fabric is in a plastically deformed state by an external force, the end portion of the fiber may protrude as shown in FIG. This will inhibit the movement of water.

도 8은 도 7의 원리를 이용한 다른 실시예를 도시한 것이다.FIG. 8 shows another embodiment using the principles of FIG. 7 .

티백(1)을 물과 접촉하기 이전에 도 8a에서와 같이 수팽창물질(10)을 소성 변형된 재료로 제작하여 두면 티가 물에 접촉하여 소정 시간을 경과하기 이전에는 물 흐름이 자연스러운 상태가 된다. 이후 소정 시간이 경과하면, 도 8b에서와 같이, 수팽창물질(10)이 원 상태로 복귀되어 물의 통로가 차단되어 물의 이동을 억제할 수 있다. 도 8에서 수팽창물질(10)은 도 7과 같은 다수층 또는 단일층으로 이루어질 수 있다.If the water expansion material 10 is made of a plastically deformed material as shown in FIG. 8a before the tea bag 1 comes into contact with water, the water flow is natural before the predetermined time elapses in contact with the water. do. After a predetermined time has elapsed, as shown in FIG. 8B, the water-expandable material 10 returns to its original state and the passage of water is blocked, thereby suppressing the movement of water. In FIG. 8 , the water-expandable material 10 may be formed of multiple layers or a single layer as shown in FIG. 7 .

도 9는 본 발명의 또 다른 실시예로, 도 9a는 수팽창물질(10)을 물에 의한 팽창률이 작은 물질로 코어부(10b)를 형성하고, 코어부(10b)를 둘러싸는 가장자리에 팽창률이 큰 테두리부(10c)를 형성한 섬유의 단면을 나타낸다.Figure 9 is another embodiment of the present invention, Figure 9a is to form a core portion (10b) of a material with a small expansion rate by water, and the expansion rate at the edge surrounding the core portion (10b) of the water-expandable material (10). A cross section of a fiber forming this large edge portion 10c is shown.

도 9b는 열팽창계수가 가장자리로 갈수록 큰 수팽창물질(10)을 도시하고 있으며, 단일 섬유소에서, 방적과 직조 과정에서 팽창률이 상이한 섬유가 섬유 중심에서 반지름 방향으로 여러 단계로 구현될 수 있다. FIG. 9B shows a water-expandable material 10 having a higher coefficient of thermal expansion toward the edges, and in a single fiber, fibers having different expansion rates during spinning and weaving may be implemented in several stages in the radial direction from the center of the fiber.

도 9의 실시예의 경우, 방직(spinning and weaving) 과정에서 물리 화학적 처리에 의해 자연스럽게 또는 인위적으로 섬유의 코어를 이루는 단일 섬유소보다 가장자리가 중심에 비해 열팽창률을 크게 제조할 수 있으므로 수팽창물질(10)의 제작이 용이하다. 수팽창물질(10)이 티백(1)을 이루면 티를 녹이는 물의 온도에 영향을 많이 받기 때문이다.In the case of the embodiment of FIG. 9, since the edge can be produced with a higher coefficient of thermal expansion than the center of a single fiber constituting the core of the fiber naturally or artificially by physicochemical treatment in the process of spinning and weaving, the water-expandable material (10 ) is easy to manufacture. This is because when the water-expandable material 10 forms the tea bag 1, it is greatly affected by the temperature of the water that dissolves the tea.

이상 본 발명의 몇 가지 실시예를 설명하였으나, 본 발명에 대해서는 다양한 변경이 가능하다. 예를 들어 티백(1)을 물 흐름이 자유로운 기존의 천 재질로 제작하고 천의 전부 또는 일부 위에 본 발명의 수팽창물질을 덧대거나 코팅하는 복합 구조로 제작하는 것도 가능하다. Although several embodiments of the present invention have been described above, various changes are possible for the present invention. For example, it is also possible to manufacture the tea bag 1 with a conventional fabric material that allows water to flow freely, and to fabricate a composite structure in which the water-expandable material of the present invention is padded or coated on all or part of the fabric.

본 발명의 권리범위는 이하 기술하는 청구범위와 동일 또는 균등한 영역에까지 미침은 자명하다.It is obvious that the scope of the present invention extends to the same or equivalent scope as the claims described below.
