Description

종이컵의 컬링부 연결구조{Structure for joining the curling part of a paper cup}Structure for joining the curling part of a paper cup}

본 발명은 종이컵의 컬링부 연결구조에 관한 것으로, 더욱 상세하게는 종이컵의 상단부에 외측으로 둥글게 말리는 컬링부중에서 옆지의 양단부가 겹쳐져서 부착되는 컬링연결부에 "V"자형 홈이나, 또는 "U"자형홈, "S"자형홈, 사선부와 같이 접착단부의 길이가 길어진 접착단확대부를 형성함으로서, 컬링부 형성을 위하여 옆지의 상단부를 성형틀에서 외측으로 말면서 가압할 때 컬링연결부에 접착단부의 길이가 길어지게 형성된 접착단확대부에서 누름력이 분산되어 작용함에 따라 컬링연결부의 접착력이 향상되고, 상기 옆지에는 비닐코팅층이 형성되어 있음에 따라 컬링연결부가 눌려질 때, 접착단확대부의 비닐코팅층이 눌려지면서 옆지두께 만큼의 단차 부분을 덮으면서 메우게 되며, 그로 인하여 컬링부 상면에 뚜껑지를 부착시 메워진 단차부분에 틈새가 생기지 않아 외부공기의 유입을 막을 수 있도록 하기 위한 것이다.The present invention relates to a curling portion connecting structure of a paper cup, and more particularly, a "V" -shaped groove, or "U" in a curling connecting portion to which both ends of the sides are overlapped and attached to the top of the paper cup. By forming an adhesive end enlargement part of which the length of the adhesive end is long, such as a female groove, an "S" shaped groove, and an oblique line, the adhesive end portion is joined to the curling connection portion when the upper end portion of the side roll is pressed outward from the mold to form the curling portion. The adhesive force of the curling connection is improved as the pressing force is dispersed in the adhesive end enlargement portion formed to have a longer length, and when the curling connection portion is pressed as the vinyl coating layer is formed on the side, the adhesive end enlargement portion As the vinyl coating layer is pressed, it fills up covering the stepped portion as much as the side thickness, and thus the stepped portion is filled when the lid is attached to the upper surface of the curling part. Gaps do not occur is to help prevent the ingress of outside air.

종래의 종이컵을 제작하는데 사용되는 옆지(1)는, 도 1에서 보는 바와 같이 전체적으로 부채꼴 모양으로 형성되어 있으며, 컬링부(3)를 형성하게 될 컬링예정부(7)의 양측 상부측 모서리부에 모따기부(8)가 형성되어 있다.The side paper 1 used to make a conventional paper cup is formed in a fan shape as shown in FIG. 1 and is formed at both upper edge portions of the curling preliminary part 7 which will form the curling part 3. The chamfer 8 is formed.

상기 옆지(1)를 이용하여 종이컵을 제작할 때는 도 3 및 도 4에서 보는 바와 같이 옆지(1)를 양단부가 겹쳐지게 테이퍼관 형태로 말은 뒤에 컬링예정부(7)를 외측으로 말아서 컬링부(3)를 형성하는데, 옆지(1)의 양단부가 겹쳐진 상태로 말린 컬링부(3)의 컬링연결부(5)는 두겹의 종이가 겹쳐진 상태이므로, 그 만큼 두께가 두꺼워지게 되어 컬링부(3) 형성을 위하여 테이퍼관 형태로 말린 옆지본체(2)의 상부를 외측으로 말을 때 두꺼워진 컬링연결부(5)가 잘 말리지 않음과 동시에 접착력이 떨어지게 된다.When manufacturing the paper cup using the side paper (1) as shown in Figures 3 and 4 roll the side paper (1) in the form of a tapered tube so that both ends overlap the curling preliminary section (7) to the outside curling ( 3), the curling connection portion 5 of the curling portion (3) dried in the state where both ends of the side edge (1) is overlapped, so that two layers of paper are overlapped, the thickness is increased so much to form the curling portion (3) In order to roll out the upper portion of the side main body (2) dried in the form of a tapered tube for the curling connection 5 is not well dried and at the same time the adhesive strength falls.

따라서, 상기 컬링예정부(7)의 상부측 양측 모서리부를 모따기한 모따기부(8)를 형성하여 옆지본체(2)의 상부를 외측으로 말을 때, 옆지(1)가 겹쳐진 상부가 잘 말릴 수 있도록 하였다. 이 모따기부(8)는 도 3 및 도 4에서 보는 바와 같이 모따기부(8) 폭을 컬링부(3)에 형성하였을 때 안쪽으로 말려 들어가는 폭(a)만큼 형성해야 한다.Therefore, when the upper portion of the side body 2 is rolled out by forming the chamfer 8 chamfering the upper side both corners of the curling preliminary portion 7, the upper side of the side 1 overlaps well. It was made. This chamfer 8 should be formed by the width (a) which rolls inward when the width of the chamfer 8 is formed in the curling part 3, as shown in FIG. 3 and FIG.

상기 모따기부(8)의 폭을 그 이상으로 넓게 형성하면 양측 모따기부(8)가 "X"자 형태로 교차되면서 그 부분을 말았을 때 컬링연결부(5)의 상면이 되는 부분(b)에 틈새가 생기는 불량이 발생하게 된다.When the width of the chamfer 8 is formed to be wider than that, both chamfers 8 cross each other in an “X” shape, and when the part is rolled up, the portion (b) which becomes the upper surface of the curling connection part 5. Defects that create gaps occur.

위와 같이 옆지(1)의 양단부가 겹쳐진 상태에서 상부를 외측으로 말아서 컬링부를 형성한 경우에 두겹의 종이가 겹쳐진 상태에서 말린 컬링연결부(5)가 도 2a 및 도 2b, 도 4 및 도 5에서 보는 바와 같이 일직선 상태로 형성되게 된다.When curling is formed by rolling the upper part outward in a state where both ends of the side paper 1 are overlapped as described above, the curling connection part 5 dried in a state where two sheets of paper are overlapped is shown in FIGS. 2A and 2B, FIGS. 4 and 5. As shown in the straight state.

이렇게 컬링연결부(5)의 단부가 일직선상태로 두껍게 형성됨에 따라 컬링부(3) 형성을 위하여 옆지의 상단부를 가열된 성형틀에서 외측으로 말면서 가압할 때, 일직선 상태로 두꺼운 컬링연결부에 누름력이 집중되어 컬링연결부(5) 바로 옆의 종이가 겹쳐지지 아니한 컬링부(3)의 접착력이 떨어지게 되는 문제가 있다.As the end of the curling connection portion 5 is formed in a thick state in a straight line, when pressing the upper end portion of the side roll outwards from the heated molding frame to form the curling portion 3, the pressing force to the thick curling connection in a straight state This concentration causes a problem that the adhesive force of the curling portion 3, in which the paper next to the curling connection portion 5 does not overlap, falls.

그리고, 이와 같은 종이컵은 컵라면이나 요구르트와 같이 상면에 뚜껑이 되는 뚜껑지(9)를 부착시키는 경우가 있는데, 컵라면과 같이 내용물이 흐르지 않는 고체인 경우는 도 2b와 같이 컬링부(3)를 둥근 상태로 유지하며 그 상면에 뚜껑지(9)를 부착시키고, 요구르트와 같이 내용물이 흐를 수 있는 액체인 경우는 도 2a와 같이 뚜껑지(9)와의 접촉면적을 확대시키기 위하여 둥글던 컬링부(3)를 납작하게 누른 뒤에 그 상면에 뚜껑지(9)를 부착시키게 된다.And, such a paper cup may be attached to the lid (9) which is a lid on the upper surface, such as cup ramen or yogurt, in the case of a solid that does not flow the contents, such as cup ramen curling portion (3) Is kept in a rounded state, and the lid 9 is attached to the upper surface, and in the case of a liquid in which the contents can flow, such as yogurt, the curling portion rounded to enlarge the contact area with the lid 9 as shown in FIG. 2A. After pressing flat (3), the cover paper 9 is attached to the upper surface.

상기와 같이 종이컵의 상면에 뚜껑지(9)를 부착시킬 때 상기 컬링연결부(5)가 그 옆의 컬링부(3) 보다 종이 두께만큼 두껍기 때문에 도 5와 같이 아주 작은 틈새(10)가 생겨서 그 틈새로 공기가 유입하여 내용물을 손상시키게 되는 문제와, 작은 벌레가 들어갈 수 있게 되는 문제가 있는 것이다.When the lid 9 is attached to the upper surface of the paper cup as described above, since the curling connection part 5 is thicker than the curling part 3 next to the paper thickness, a very small gap 10 is formed as shown in FIG. There is a problem that air enters the gap and damages the contents, and a small bug can enter.

따라서, 본 발명은 상기의 문제점을 해결하기 위하여 컬링연결부에 "V"자형 홈이나, 또는 "U"자형홈, "S"자형홈, 사선부와 같이 접착단부의 길이가 길어진 접착단확대부를 형성함으로서, 컬링부 형성을 위하여 옆지의 상단부를 성형틀에서 외측으로 말면서 가압할 때 접착단부의 길이가 길어진 접착단확대부에서 누름력이 분산되어 작용함에 따라 컬링연결부의 접착력이 향상되게 되고, 옆지에는 비닐코팅층이 형성되어 있음에 따라 컬링연결부가 눌려질 때 접착단확대부의 비닐코팅층이 눌려지면서 퍼져서 옆지두께 만큼의 단차부분을 덮으면서 메워지게 되며, 그로 인하여 컬링부 상면에 뚜껑지를 부착시킬 때 메워진 단차부분에 틈새가 생기지 않아 외부공기가 유입되는 것을 막을 수 있도록 하는 것을 기술적 과제로 한다.Therefore, in order to solve the above problems, the present invention provides an adhesive end enlargement portion in which the length of the adhesive end is increased, such as a "V" -shaped groove or a "U" -shaped groove, an "S" -shaped groove, and an oblique portion, in order to solve the above problem. By pressing the upper end of the side roll to the outer side in the mold to form the curling portion by the pressing force is dispersed in the bonding end enlargement length of the length of the bonding end is improved, the adhesion of the curling connection is improved, As the vinyl coating layer is formed on the paper, when the curling connection is pressed, the vinyl coating layer of the adhesive end enlargement is pressed and spread to fill the cover covering the step portion of the side thickness, thereby attaching the lid to the upper surface of the curling portion. The technical problem is to prevent the inflow of external air due to no gap in the gap.

상기와 같이 구성되어 있는 본 발명의 작용 관계를 도 6 내지 도 11c를 참고하여 설명하면 다음과 같다.Referring to Figures 6 to 11c the operational relationship of the present invention configured as described above are as follows.

옆지(1)의 양단부가 겹쳐지게 부착하여 테이퍼관 형태의 옆지본체(2)를 형성한 뒤에, 이 옆지본체(2)의 상부를 외측으로 말면서 컬링부(3)를 형성할 때, 접착단확대부(6)를 형성한 컬링연결부(5)는 옆지가 겹쳐져서 두겹이 된 상태에서 외측으로 말리게 된다.When both ends of the side paper 1 are attached to each other so as to form a side pipe body 2 in the form of a tapered tube, and the curling part 3 is formed while rolling the upper portion of the side body 2 outward, The curling connection part 5 forming the enlarged part 6 is rolled outward in a state where the side edges overlap and are doubled.

이때, 상기 컬링연결부(5)에는 "V"자형 홈이나, 또는 "U"자형홈, "S"자형홈, 사선부와 같이 접착단부의 길이가 길어진 접착단확대부(6)가 형성되어 있음에 따라 컬링부 형성을 위하여 옆지의 상단부를 성형틀에서 외측으로 말면서 가압할 때, 컬링연결부(5)에는 접착단부의 길이가 길어진 접착단확대부(6)가 형성되어 누름력이 작용하는 성형틀면과의 접촉면적이 확대된 것이므로 접착단확대부(6)에서 누름력이 분산되어 작용하게 된다.At this time, the curling connection part 5 is formed with an adhesive end enlargement part 6 having a length of an adhesive end length such as a "V" shape groove, or an "U" shape groove, an "S" shape groove, and an oblique portion. When pressing the upper end of the side roll to the outer side in the molding frame to form the curling portion, the curling connection portion 5 is formed with an adhesive end enlargement portion 6 with a length of the adhesive end length is formed by pressing force Since the contact area with the mold surface is enlarged, the pressing force is dispersed in the adhesive end enlargement part 6 to act.

이렇게 접착단부의 길이가 길어지게 형성된 접착단확대부(6)에서 누름력이 분산되어 작용함에 따라 접착단확대부(6)의 전길이에 고르게 누름력이 작용하게 되고, 상기와 같은 고른 누름력에 의해 컬링연결부(5)를 포함한 컬링부(3) 전둘레가 둥글게 말리면서 접착되게 된다.As the pressing force is distributed and acts on the adhesive end enlargement part 6 which is formed to have a length of the adhesive end length, the pressing force is evenly applied to the entire length of the adhesive end enlargement part 6 and the even pressing force as described above. By curling the curled portion 3 including the curling connection portion 5 is rolled round and bonded.

이때, 도 8 내지 도 10에서 보는 바와 같이 상기 컬링연결부(5)에는 "V"자형 홈이나, 또는 "U"자형홈, "S"자형홈, 사선부와 같이 접착단부의 길이가 길어진 접착단확대부(6)가 형성되어 있음에 따라 컬링연결부(5)가 눌려질 때, 상기 누름력에 의해 접착단확대부(6)의 단부측 비닐코팅층(12)이 고르게 눌리면서 퍼지게 되며, 이렇게 퍼지는 비닐은 접착단확대부(6)의 옆지두께 만큼의 단차부분을 덮으면서 압착되게 된다.In this case, as shown in FIGS. 8 to 10, the curling connection part 5 has an adhesive end having a length of an adhesive end such as a "V" -shaped groove, or an "U" -shaped groove, an "S" -shaped groove, and an oblique portion. When the curling connection portion 5 is pressed as the enlarged portion 6 is formed, the end-side vinyl coating layer 12 of the adhesive end enlargement portion 6 is evenly spread by the pressing force and spreads. Is pressed while covering the stepped portion as much as the side thickness of the adhesive end enlargement portion 6.

상기 접착단확대부(6)는 위에서 설명한 바와 같이 접착단부의 길이가 길어졌으므로 그 만큼 접착길이(면적)이 길어져 접착력이 향상되게 되는 것이며, 상기 단차부분을 넓게 펼쳐지는 눌린 비닐이 메우게 되어 컬링부(3)의 상면에 뚜껑지(9)를 부착시킬 때 컬링부와 뚜껑지의 사이에 틈새가 생기지 않게 되는 것이다.Since the adhesive end enlargement portion 6 has a longer adhesive end length as described above, the adhesion length (area) is increased by that length, and thus the adhesive force is improved, and the pressed vinyl which widens the stepped portion is filled with curling. When the lid 9 is attached to the upper surface of the part 3, there is no gap between the curling part and the lid.

그리고, 요구르트와 같은 액체상태의 내용물을 담는 컬링부가 납작한 종이컵의 경우에는 컬링부 성형틀에 히터가 내장되어 컬링부를 형성하며 납작하게 누를 때, 컬링부 성형틀의 열기에 의해 접착단확대부(6)의 단부의 비닐코팅층이 전길이에 걸쳐 녹으면서 하측에 겹쳐진 컬링연결부(5)와 접착되어 접착력이 더욱 더 향상되게 되고, 접착단의 길이가 길어진 접착단확대부(6)의 옆지두께 만큼의 단차가 용융비닐(13)에 의해 메워지게 된다.And, in the case of a flat cup of curling portion containing the contents of the liquid state, such as yogurt, the heater is built in the curling portion forming mold to form a curling portion, and when pressed flatly, the adhesive end enlargement portion (6) As the vinyl coating layer at the end of the sheet melts over the entire length, it is adhered to the curling connection part 5 superimposed on the lower side so that the adhesive force is further improved, and the length of the adhesive end is increased by the side thickness of the adhesive end enlargement part 6. The step is filled by the molten vinyl 13.

상기와 같이 접착단확대부(6)의 단부 비닐이 녹은 용융비닐(13)이 옆지두께 만큼의 단차부분이 용융비닐(13)에 의해 메워져 컬링부(3) 상면에 뚜껑지(9)를 부착시킬 때, 메워진 단차부분에 틈새가 생기지 않아 외부공기의 유입을 막을 수 있고, 작은 벌레의 유입을 방지할 수 있는 것이다.As described above, the stepped portion of the molten vinyl 13 in which the end vinyl of the adhesive end enlargement part 6 is melted is filled by the molten vinyl 13 so that the lid 9 is attached to the upper surface of the curling part 3. When it is made, it is possible to prevent the inflow of external air because there is no gap in the filled step portion, and to prevent the introduction of small insects.

상기와 같이 본 발명의 종이컵의 컬링부 연결구조는, 컬링연결부에 "V"자형 홈이나, 또는 "U"자형홈, "S"자형홈, 사선부와 같이 접착단부의 길이가 길어진 접착단확대부를 형성함으로서, 컬링부 형성을 위하여 옆지의 상단부를 성형틀에서 외측으로 말면서 가압할 때 접착단부의 길이가 길어진 접착단확대부에서 누름력이 분산되어 작용함에 따라 컬링연결부의 접착력이 향상되는 효과와, 옆지에는 비닐코팅층이 형성되어 있음에 따라 컬링연결부가 눌려질 때 접착단확대부의 비닐코팅층이 퍼지면서 옆지두께 만큼의 단차부분을 덮어서 단차부분이 메워지게 부착되게 되며, 그로 인하여 컬링부 상면에 뚜껑지를 부착시켰을 때 메워진 단차부분에 틈새가 생기지 않아 외부공기가 유입되는 것을 막아 종이컵의 내부에 담긴 내용물의 손상과, 작은 벌레의 유입도 막을 수 있는 효과가 있는 것이다.The curling portion connecting structure of the paper cup of the present invention as described above, the length of the adhesive end is extended, such as "V" -shaped groove, or "U" -shaped groove, "S" -shaped groove, oblique portion in the curling connection portion By forming the portion, when pressing the upper end of the side roll to the outer side in the forming mold to form the curling portion, the adhesive force of the curling connection is improved as the pressing force is dispersed and acts at the adhesive end enlargement portion where the length of the adhesive end is extended. And, since the vinyl coating layer is formed on the side surface, when the curling connection is pressed, the vinyl coating layer of the adhesive end enlargement spreads to cover the stepped portion as much as the side thickness, so that the stepped portion is filled with the top surface of the curling portion. When the lid is attached to the inside of the paper cup, there is no gap in the gap that prevents the inflow of external air and damages the inside of the paper cup. Size will be effective to stop.
