이러한 본 발명에 의하면 압력 용기에 입체적인 형상 및 색감, 질감을 부여할 수 있기 때문에 이러한 압력 용기를 사용하는 제품의 광고 홍보 효과를 제고하는데 도움이 될 수 있다.According to the present invention, since the three-dimensional shape, color, and texture may be imparted to the pressure vessel, it may be helpful to improve the advertisement promotion effect of the product using the pressure vessel.
그리고, 다양한 형태의 패턴이나 글자, 문양, 숫자, 그림들을 금형 캐비티 내부에 형성함으로써 다양한 입체 형상을 구현할 수 있다.In addition, various three-dimensional shapes may be realized by forming various types of patterns, letters, patterns, numbers, and pictures in the mold cavity.
종래 입체 형상의 경우, 열수축 방식을 통하거나, 직접 부착방식을 사용할 수 밖에 없었는데, 용기의 입체 형상 부분과, 입체 형상을 커버해야할 라벨의 인쇄면(글자, 그림, 패턴, 문양, 숫자 등)의 경계가 맞지 않았다.In the case of the conventional three-dimensional shape, it was forced to use a heat shrink or direct attachment method, but the three-dimensional portion of the container and the printing surface (letters, drawings, patterns, patterns, numbers, etc.) of the container to cover the three-dimensional shape The border was not right.
그러나, 본 발명의 경우, 인몰드 라벨 및 블로윙 방식을 통하여 큰 힘으로 입체 형상이 형성됨과 동시에 입체 형상 부분에 라벨의 대응 부분이 정확하게 밀착되게 함으로써 심미감과 배치 정확도를 구현하는 압력 용기를 제공하는데 그 장점이 있다.

도1에서 도시한 바와 같이, 본 발명에 의한 인몰드 라벨(200)을 구비하는 압력 용기(100)는 입구부(110)와, 입구부(110)보다 직경이 큰 몸체부(120)로 구성되어 있다.As shown in FIG. 1, the pressure vessel 100 including the in-mold label 200 according to the present invention includes an inlet 110 and a body 120 having a larger diameter than the inlet 110. It is.
몸체부(120)의 외주면에는 라벨(200)이 부착되어 있으며, 라벨(200)의 테두리에는 인몰드 라벨링이 되면서 형성되는 단차부(121)가 형성된다.A label 200 is attached to an outer circumferential surface of the body part 120, and a stepped part 121 is formed on the edge of the label 200 while being in-mold labeling.
이는 압력용기(100)의 팽창과정에서 라벨(200)과 접촉하면서 라벨(200)이 부착되는 부분과, 라벨(200)이 부착되지 않은 부분간에 단차가 형성되는 것이며, 라벨(200)이 부착되지 않은 부분이 라벨(200)이 부착된 부분보다 약간 밖으로 돌출되어 있는 형태가 된다.This is a step in which a step is formed between the portion to which the label 200 is attached and the portion to which the label 200 is not attached while contacting the label 200 during the expansion of the pressure vessel 100, and the label 200 is not attached. The portion that is not formed protrudes slightly out of the portion to which the label 200 is attached.
라벨(200)은 기재부(201)와, 기재부(201) 외면에 마련되어 압력 용기(100) 외주면에 형성되는 입체부(도2참조, 122)에 위치하며 입체부(122)의 형상에 맞게 돌출되거나 리세스 처리되어 입체감을 형성하는 인쇄층(202)이 마련된다.The label 200 is disposed on the base portion 201 and the three-dimensional portion (see FIG. 2, 122) formed on the outer surface of the substrate portion 201 and formed on the outer circumferential surface of the pressure vessel 100 to meet the shape of the three-dimensional portion 122. A printed layer 202 is provided which protrudes or is recessed to form a three-dimensional effect.
기재부(201)의 후면에는 접착층(도5참조, 203)이 형성되며 이 접착층(203)은 인몰드 라벨링 공정 중에 표면 온도가 높은 팽창된 프리폼(압력 용기를 형성할 프리폼)의 표면과 융착되어 라벨(200)을 압력 용기(100) 표면에 부착시킨다. An adhesive layer (see Fig. 5, 203) is formed on the back side of the substrate portion 201, and the adhesive layer 203 is fused with the surface of the expanded preform (preform to form a pressure vessel) having a high surface temperature during the in-mold labeling process. The label 200 is attached to the pressure vessel 100 surface.
라벨(200)이 압력 용기(100)의 몸체부(120)에 부착된 상태를 보면 압력 용기(100)의 몸체부 표면에 형성된 입체부(122)에 라벨(200)의 인쇄층(202)이 위치하기 때문에 인쇄층(202)이 외측면으로 도드라져 보이게 된다.When the label 200 is attached to the body portion 120 of the pressure vessel 100, the printing layer 202 of the label 200 is formed on the three-dimensional portion 122 formed on the surface of the body portion of the pressure vessel 100. Since it is located, the printed layer 202 is raised to the outside surface.
특히 인쇄층(202)이 눈에 띠는 반사층이나 홀로그램층으로 되어 있는 경우, 이를 보는 사람의 시각의 방향에 따라서 비춰지는 색상이 달라지기 때문에 이를 바라보는 사람의 관심이나 시선을 주목시킬 수 있다는 장점이 있다.In particular, when the print layer 202 is a visible reflective layer or a hologram layer, the color of the light is changed depending on the direction of the viewer's vision. There is this.
도1에서 음영으로 처리된 부분은 인쇄층(202) 중 홀로그램층 또는 반사층으로 처리된 부분이며, 이러한 부분의 경우, 3D 입체 구조를 보다 현저하게 부각시킬 수 있다는 장점이 있다.In FIG. 1, the shaded portion is a portion treated with a hologram layer or a reflective layer among the print layers 202, and in this case, the 3D structure may be more remarkably emphasized.
도2는 라벨(200)을 압력 용기(100)의 몸체부(120)에서 떼어낸 상태를 도시한 것이다.2 shows a state in which the label 200 is detached from the body 120 of the pressure vessel 100.
본 발명에 따른 압력 용기(100)에 부착되는 라벨(200)은 원래 3차원 구조로 형성되기 보다는 평면적인 2차원 구조로 형성된다.The label 200 attached to the pressure vessel 100 according to the present invention is formed in a planar two-dimensional structure rather than originally formed in a three-dimensional structure.
다만, 압력 용기(100) 몸체부(120)의 입체부(122) 위에 덮여질 부분에 대해서는 인쇄층(202)을 형성하고, 이 부분에 반사층이나 홀로그램 층을 처리하거나 또는 기재부(201)의 표면 색상과 다른 색상이나 패턴, 문양, 숫자, 글자, 그림 등이 형성되도록 한다.However, for the portion to be covered on the three-dimensional portion 122 of the body portion 120 of the pressure vessel 100, a printing layer 202 is formed, and the reflective layer or the hologram layer is treated on this portion or the base portion 201 Make sure that colors, patterns, patterns, numbers, letters, and pictures are different from the surface colors.
원래 2차원적인 형태의 라벨(200)이 인몰드 라벨링에 의하여 압력 용기(100)의 몸체부(120)의 입체부(122)가 형성되면서 발생하는 압력에 의하여 변형되어 3차원적인 구조로 변한다.The original two-dimensional label 200 is deformed by the pressure generated while the three-dimensional portion 122 of the body portion 120 of the pressure vessel 100 by the in-mold labeling is changed into a three-dimensional structure.
압력 용기(100)의 몸체부(120)의 표면에 입체부(122)가 형성되고, 입체부(122)는 몸체부(122)의 다른 표면보다 외부로 돌출되거나 리세스 처리되어서 다른 표면과의 경계가 명확해진다.The three-dimensional portion 122 is formed on the surface of the body portion 120 of the pressure vessel 100, the three-dimensional portion 122 is protruded or recessed outward than the other surface of the body portion 122 and the other surface The boundary becomes clear.
그리고, 입체부(122)의 경계와 라벨(200)의 인쇄층(202)의 경계는 상호 일치되거나 거의 유사한 위치에 배치됨으로써 입체부(122)의 윤곽이 라벨(200)의 인쇄층(202)에서 그대로 드러날 수 있도록 한다.In addition, the boundary of the three-dimensional portion 122 and the boundary of the printed layer 202 of the label 200 are disposed at the same or substantially similar position, so that the outline of the three-dimensional portion 122 is printed on the printed layer 202 of the label 200. To be revealed as is.
한편, 라벨(200)이 부착될 지점의 테두리에 보이는 선은 단차부(121)를 나타내며, 이러한 단차부(121)는 인몰드 라벨링 과정에서 라벨링이 되는 부분과 라벨링이 되지 않은 부분과의 경계를 형성한다. On the other hand, the line visible on the border of the point to which the label 200 is to be attached represents the stepped portion 121, the stepped portion 121 is a border between the portion that is labeled and the unlabeled portion in the in-mold labeling process Form.
도3에서 도시한 바와 같이, 3차원 입체구조가 형성되며 라벨링이 된 압력 용기(100)를 옆에서 보면, 입체부(122) 및 입체부(122)를 덮고 있는 인쇄층(202)이 외측으로 도드라져 보이게 되고, 이는 입체부(122)가 없는 표면과의 시각적인 윤곽 차이를 현저하게 유발시킨다. As shown in Fig. 3, when the three-dimensional solid structure is formed and the pressure vessel 100 labeled is viewed from the side, the three-dimensional portion 122 and the printing layer 202 covering the three-dimensional portion 122 are directed outward. It will appear raised, which causes significant visual contour differences with surfaces without the solid portion 122.
도4에서 도시한 바와 같이, 압력 용기(100)에 형성되는 입체부(122)는 다른 부분보다 외측으로 돌출되는 형태로 마련되어 다른 부분에 비해서 도드라지게 형성된다. As shown in FIG. 4, the three-dimensional portion 122 formed in the pressure vessel 100 is formed to protrude outward from other portions, and is formed to be stronger than other portions.
그리고 입체부(122)에서도 다양한 정도로 돌출되는 부분이 형성되는데, 이 부분이 글자, 숫자, 그림, 모양, 패턴, 문양 등을 형성하여 이를 바라보는 사람들의 주목을 끌 수 있다.In addition, the three-dimensional portion 122 is formed to protrude to a different degree, this portion may form the letters, numbers, pictures, shapes, patterns, patterns, etc. can attract the attention of those looking at them.
이러한 입체부(122) 위에 라벨(200)이 부착되고, 그러한 라벨(200)의 표면에 인쇄층(202)이 매칭되게 위치하고, 입체부(122)에 의하여 돌출됨으로써, 형상적인 면 뿐만 아니라 색상이나 반사율, 홀로그램을 통해서 더욱더 시선을 끌수 있다는 장점이 있다.The label 200 is attached to the three-dimensional portion 122, the print layer 202 is matched to the surface of the label 200, and protruded by the three-dimensional portion 122, so that not only the shape but also the color It has the advantage of attracting more attention through reflectance and hologram.
여기서 인쇄층(202)의 경계면은 입체부(122)의 경계면에 대응되는 것이 바람직하다.Here, the boundary surface of the printed layer 202 preferably corresponds to the boundary surface of the three-dimensional portion 122.
후술하겠지만, 압력 용기(100)에 입체부(122)가 형성될 수 있는 것은, 블로윙 작업에 사용되는 금형 내부에 입체부(122)에 정확히 매칭되는 입체홈(도9, 322)이 형성되기 때문이며, 라벨(200)의 인쇄층(202)은 정확하게 이러한 입체홈(322)을 가리도록 배치되어야 한다.As will be described later, the three-dimensional portion 122 can be formed in the pressure vessel 100, because the three-dimensional groove (Fig. 9, 322) that is exactly matched to the three-dimensional portion 122 is formed inside the mold used for the blowing operation. The print layer 202 of the label 200 should be positioned to exactly cover this three-dimensional groove 322.
이 상태에서 프리폼(도9, PF)이 팽창하면, 입체홈(322)을 향해서 팽창하는 부분이 라벨(200)을 입체홈(322) 내면으로 밀면서 입체부(122)를 형성하는 동시에 라벨에서도 입체적인 형상이 나타나게 할 수 있는 것이다. In this state, when the preform (FIG. 9, PF) expands, the portion expanding toward the three-dimensional groove 322 pushes the label 200 to the inner surface of the three-dimensional groove 322 to form the three-dimensional portion 122, and at the same time, the three-dimensional portion of the preform (FIG. The shape can appear.
도5는 입체 용기(100)와 라벨(200)을 분리한 상태를 나타낸 것이다. 5 shows a state in which the three-dimensional container 100 and the label 200 are separated.
라벨(200)이 입체용기(100)에 부착된 상태에서 변형이 된 이후에 라벨(200)을 떼어내면 열변형 및 물리적인 변형에 의하여 라벨(200)의 인쇄층(202)에 해당하는 부분이 압력 용기(100)의 입체부(122)의 형상에 맞게 입체적이 형상으로 변형된다.When the label 200 is detached after the label 200 is deformed in the state in which the label 200 is attached to the three-dimensional container 100, a portion corresponding to the print layer 202 of the label 200 is formed by thermal deformation and physical deformation. The three-dimensional shape is modified to match the shape of the three-dimensional portion 122 of the pressure vessel 100.
다만, 상술한 바와 같이, 라벨(200)은 원래 2차원적인 구조로서 평면을 형성하고 있고, 기재부(201)의 외면에는 평면의 인쇄층(202)이, 기재부(201)의 내면에는 접착층(203)이 형성된다.However, as described above, the label 200 originally forms a plane as a two-dimensional structure, the flat printing layer 202 on the outer surface of the base portion 201, the adhesive layer on the inner surface of the base portion 201 203 is formed.
도 6 내지 도8은 압력 용기(10)에 그림(예, 용 모양)이 입체적인 형태로 표현된 것을 나타낸 것이다.6 to 8 show that the figure (eg, dragon shape) is expressed in three-dimensional form on the pressure vessel (10).
도 1 내지 도5는 글자를 입체적인 형상으로 표현한 것이 가능함을 나타낸 것이라면, 도6 내지 도8은 글자 이외에도 복잡한 형태의 그림이나 패턴이 가능함을 내기 위하여 제공된 것이다.1 to 5 are to show that it is possible to represent the letters in a three-dimensional shape, Figures 6 to 8 are provided to show that a complex picture or pattern in addition to the letters are possible.
여기서도 원래의 라벨0)에는 용 모양이 2차원적인 평면적 형태로 인쇄된다. Here too, the dragon label is printed in a two-dimensional planar form.
그러나, 블로윙 공정에 사용될 금형 캐비티 내면에 용 모양의 입체홈이 형성되고, 그 입체홈 위에 용 모양의 그림이 정확하게 매칭되게 부착된 이후에, 프리폼이 공기 주입에 의하여 팽창되면 용 모양의 입체홈으로 이동하는 프리폼의 표면의 팽창에 의하여 용기의 표면에 입체홈 형태의 입체부가 형성된다.However, after the dragon-shaped three-dimensional groove is formed on the inner surface of the mold cavity to be used in the blowing process, and the dragon-shaped figure is accurately attached to the three-dimensional groove, the preform is expanded by air injection into a dragon-shaped three-dimensional groove. The expansion of the surface of the moving preform forms a three-dimensional groove-shaped solid portion on the surface of the container.
그리고, 이에 의하여 용모양의 그림이 있는 인쇄층(1202)도 정확하게 입체감을 가지며 3차원 형태로 변환될 수 있다. In addition, the printed layer 1202 having a dragon-shaped drawing can be converted into a three-dimensional form with a precise three-dimensional effect.
도9(a) 내지 도9(d)는 본 발명에 따른 인몰드 라벨을 구비하는 압력 용기가 제작되는 공정을 도시한 것이다. 9 (a) to 9 (d) illustrate a process of manufacturing a pressure vessel having an in-mold label according to the present invention.
도9(a)에서 도시한 바와 같이, 압력 용기(100)의 형상을 제작하기 위한 금형(310, 320)을 상호 이격시킨다.As shown in Fig. 9 (a), the molds 310 and 320 for producing the shape of the pressure vessel 100 are spaced apart from each other.
금형 중 어느 하나(320)의 캐비티 내면에는 입체부(도2참조, 122)를 형성하기 위한 입체홈(322)이 형성되어 있다.A three-dimensional groove 322 for forming a three-dimensional portion (see FIG. 2, 122) is formed in the cavity inner surface of any one of the molds 320.
금형(310, 320)에는 라벨(200)이 부착되는 경우, 라벨(200)을 진공흡착하기 위한 흡착 유로(311, 321)가 형성된다.When the label 200 is attached to the molds 310 and 320, adsorption flow paths 311 and 321 for vacuum adsorption of the label 200 are formed.
금형(310, 320)이 열려진 상태에서 금형(310, 320)의 위에 있는 라벨 공급 장치(400) 수직 암(4001)에 하강하여 라벨(200)을 금형(310, 320) 내부로 이동시킨다.With the molds 310 and 320 open, the label 200 is moved to the label arms 4001 vertical arm 4001 on the molds 310 and 320 to move the label 200 into the molds 310 and 320.
그리고, 라벨 공급 장치(400) 수직암(401)에는 수평 방향으로 신축가능하게 움직이는(또는 텔레스코픽 다단 방식으로 움직이는) 파이프(403)가 마련된다.In addition, the vertical arm 401 of the label supply device 400 is provided with a pipe 403 which is elastically movable in the horizontal direction (or moves in a telescopic multistage manner).
파이프(403)에도 진공 흡착력이 있어서 라벨(200)이 파이프(403)에 부착된 상태가 되게 한다.The pipe 403 also has a vacuum suction force such that the label 200 is attached to the pipe 403.
이 상태에서 파이프(403)가 각각의 금형 내면을 이동하면 파이프(403)에 부착된 라벨(200)이 금형 내부에 부착된다. In this state, when the pipe 403 moves each mold inner surface, the label 200 attached to the pipe 403 is attached to the inside of the mold.
금형(310, 320) 내면에 진공 흡입압에 의하여 라벨(200)이 부착되면, 파이프 (403)내면의 진공압이 해제된다..When the label 200 is attached to the inner surfaces of the molds 310 and 320 by the vacuum suction pressure, the vacuum pressure on the inner surface of the pipe 403 is released.
이 상태에서 파이프(403)가 원상복귀하면, 라벨(200)은 캐비티 내면에 부착된 상태를 유지한다.When the pipe 403 returns to its original state in this state, the label 200 remains attached to the cavity inner surface.
이 때, 입체홈(322)의 경계면과 라벨(200)의 인쇄층(도2참조, 202)의 경계면이 일치되게 위치하는 것이 바람직하다At this time, the boundary surface of the three-dimensional groove 322 and the boundary surface of the printing layer (see Fig. 2, 202) of the label 200 is preferably located to match.
라벨(200)은 2차원적인 평면이기 때문에, 입체홈(322)의 내면에는 들어가지 않고 입체홈(322)을 덮고 있는 상태가 된다.Since the label 200 is a two-dimensional plane, the label 200 does not enter the inner surface of the three-dimensional groove 322 to cover the three-dimensional groove 322.
이 상태에서 프리폼(700)이 립 플레이트(600)에 거꾸로 배치된 상태로 열려진 금형(310, 320) 사이로 들어온다.In this state, the preform 700 enters between the opened molds 310 and 320 in a state in which the preform 700 is disposed upside down on the lip plate 600.
그리고, 금형(310, 320)의 상부에는 나중에 압력 용기(100)의 바닥면을 형성하기 위한 바닥 형성부(500)가 배치된다.Then, the bottom forming portion 500 for forming the bottom surface of the pressure vessel 100 is disposed on the upper portion of the mold (310, 320).
그리고 도9(c)에서 도시한 바와 같이, 금형(310, 320)이 닫히고, 바닥 형상부(500)도 금형(310, 320)의 상부를 밀폐한다. As shown in FIG. 9C, the molds 310 and 320 are closed, and the bottom portion 500 also seals the upper portions of the molds 310 and 320.
이 상태에서 금형(310, 320)의 하부는 립 플레이트(600)에 의하여 폐쇄된다.In this state, the lower portions of the molds 310 and 320 are closed by the lip plate 600.

이 상태에서 공기가 주입되면, 도9(d)에서 도시한 바와 같이, 프리폼(700)이 팽창하여 밀폐된 금형(310, 320) 캐비티 내면의 형상에 맞게 변형된다.When air is injected in this state, as shown in FIG. 9 (d), the preform 700 expands and deforms to conform to the shape of the inner surfaces of the cavity 310 and 320 closed.
특히, 프리폼(700)의 표면 중 일부가 입체홈(322)을 향해서 이동하는 경우에, 표면 일부는 입체홈(322)을 덮고 있는 라벨(200)을 가압하고, 라벨(200)을 입체홈(322) 형상에 맞게 변형시킨다.In particular, when a part of the surface of the preform 700 is moved toward the three-dimensional groove 322, the surface portion presses the label 200 covering the three-dimensional groove 322, the label 200 is a three-dimensional groove ( 322) to conform to the shape.
도4 및 도5에서 상술한 바와 같이, 라벨(200)의 내면에는 접착층(203)이 형성되고, 이 접착층(203)은 일정 온도 (예, 50℃) 이상의 분위기에서 녹아서 밀착될 수 있기 때문에, 뜨거운 프리폼(700)의 표면 온도 및 금형(310, 320)의 온도에 의하여 프리폼(700)의 표면과 밀착되면 녹아서 라벨(200)을 압력 용기(100) 표면에 단단하게 고정시킨다.As described above with reference to FIGS. 4 and 5, the adhesive layer 203 is formed on the inner surface of the label 200, and the adhesive layer 203 may be melted and adhered in an atmosphere of a predetermined temperature (eg, 50 ° C.) or more, The surface 200 of the hot preform 700 and the temperature of the molds 310 and 320 melt and adhere to the surface of the preform 700 to firmly fix the label 200 to the surface of the pressure vessel 100.
그리고, 입체홈(322)에 의하여 압력 용기 표면에 입체부(도2참조, 122)가 형성되되, 그 입체부(122)는 라벨(200)에 의하여 덮여서 라벨(200)과 함께 형상적으로, 시각적으로 입체적인 특징을 압력 용기에 부여할 수 있다. Then, the three-dimensional portion (see Fig. 2, 122) is formed on the surface of the pressure vessel by the three-dimensional groove 322, the three-dimensional portion 122 is covered by the label 200 to be in shape with the label 200 Therefore, a visual three-dimensional feature can be given to the pressure vessel.
여기서 입체적인 형상을 구현하기 위한 압력 용기(100)의 형성을 위해서 주입되는 공기의 압력은 30~40 bar 인 것이 바람직하나, 이에만 한정되지 않고 더 늘어날 수 있다. Herein, the pressure of the air injected to form the pressure vessel 100 for implementing the three-dimensional shape is preferably 30 to 40 bar, but is not limited thereto.
그리고, 라벨(200)이 압력 용기(100) 표면에 단단하게 부착하도록 접착층(202)이 용이하게 융착될 수 있게, 금형(310,320)의 표면 온도를 40~80℃로 유지하는 것이 바람직하다. In addition, the surface temperature of the molds 310 and 320 may be maintained at 40 ° C. to 80 ° C. so that the adhesive layer 202 may be easily fused so that the label 200 may be firmly attached to the surface of the pressure vessel 100.
