본 발명은 종이컵용 옆지에 관한 것으로, 더욱 상세하게는 종이컵을 제작하는데 사용되는 옆지의 상단부와 하단부에 다수개의 열기침투홈을 형성함으로서, 종 이컵 제작을 위하여 옆지를 테이퍼관 형태로 말은 뒤에 옆지의 상단부를 외측으로 말아서 컬링부를 형성할 때와, 옆지의 하단부를 내측으로 절곡시켜 밑굽을 형성할 때 상기 다수의 열기침투홈으로 열풍이 들어가 옆지의 내면에 코팅된 비닐코팅층이 녹으면서 컬링부와 밑굽이 작은 하중으로도 성형이 잘 되도록 하고, 종이컵 상단의 컬링부를 납작하게 형성하는 경우에 납작하게 형성되는 납작컬링부가 단단하게 접착될 수 있도록 하기 위한 것이다.The present invention relates to a side for paper cups, and more particularly, by forming a plurality of hot penetrating grooves in the upper and lower ends of the side used to make the paper cup, the side in the form of tapered pipe for making paper cups When curling the upper end of the paper outward to form a curling, and when bending the lower end of the side inward to form a heel hot air enters into the plurality of hot penetrating grooves and the coating of the coating and the coating of the coating on the inner surface of the side melt The heel is intended to be molded well even with a small load, and to form a flat curling portion that is formed flat when the curling portion of the upper end of the paper cup is flat.

종래의 일반적인 종이컵은 도 1 및 도 2에서 보는 바와 같이 상단부와 하단부가 전체적으로 호형상으로 형성된 옆지(1)를 테이퍼관 형태로 말은 뒤에 이 테이퍼관 형태로 형성된 옆지(1)의 상단부에 외측으로 동그랗게 말린 컬링부(2)를 형성하고, 외주연 전둘레가 하향 절곡되어 하향절곡부(3)를 형성한 밑지(4)를 옆지(1)의 하단부 내측으로 삽입시키며, 이 상태에서 옆지(1)의 하단부를 내측으로 절곡시키면서 내측으로 절곡되는 감쌈부(5)로 하향절곡부(3)를 감싸고, 이렇게 하향절곡부(3)를 감싸진 감쌈부(5)를 압착하여 하향절곡부(3)와 감쌈부(5)을 결합하여 밑굽(7)을 형성하는 종이컵(8)을 제작하게 된다.As shown in FIGS. 1 and 2, a conventional paper cup is rolled up a side 1 formed in an arc shape as a whole with an upper end and a lower end in a tapered tube shape, and then outwardly at the upper end of a side 1 formed in a tapered tube shape. The curled curling part 2 is formed in a round shape, and the base 4 having the outer circumferential edge is bent downward to insert the lower bent part 3 into the lower part of the side 1, and in this state the side edge 1 The lower bent portion (3) is wrapped inside the downward bent portion (3) with a wrapping portion (5) that is bent inwardly, and the downwardly bent portion (3) by pressing the wrapped portion (5) wrapped around the downward bending portion (3) ) And the wrapping portion (5) to produce a paper cup (8) to form a heel (7).

상기와 같이 종이컵을 제작하는 과정 중에 상측에 컬링부(2)를 형성할 때, 컬링부(2)의 상단부는 동그랗게 말게 되는데, 이때는 동그란 홈을 형성한 금형에 옆지(1)의 상단부를 삽입시켜서 동그란 컬링부(2)를 형성시킨 다음에 뒤이어 동그랗게 말린 컬링부(2)에 열풍을 불어주어 일측면에 비닐층이 코팅된 옆지(1)의 상단 컬링부(2)의 비닐층이 녹으면서 동그랗게 말은 컬링부(2)가 풀리지 않도록 하고 있다.When forming the curling portion (2) in the upper side during the process of manufacturing the paper cup as described above, the upper end of the curling portion (2) is rolled round, in this case by inserting the upper end of the side (1) in the mold forming a round groove After the round curling part 2 is formed, a hot air is blown into the curled curling part 2, followed by melting the vinyl layer of the upper curling part 2 of the side sheet 1 coated with a vinyl layer on one side thereof. The horse prevents the curling portion 2 from loosening.

그리고, 밑굽(7)을 형성하는 경우에도 하측으로 하향 절곡된 하향절곡부(3)에 감쌈부(5)를 감싼 뒤에 열풍으로 불어 넣으면서 널링구를 이용하여 하향절곡부(3)를 감싼 감쌈부(5)를 압착시켜서 하향절곡부(3)와 감쌈부(5)가 견고하게 접착되도록 한다.And, in the case of forming the heel (7) wrapped around the wrap section (5) in the downward bent portion (3) bent downward downward and blow into the hot air while the wrap section wrapped around the down bent section (3) by using a knurled ball (5) is pressed so that the downward bent portion (3) and the wrap (5) is firmly bonded.

그런데, 상측의 컬링부(2)를 형성할 때 도 1의 부분 확대도에서 보는 바와 같이 동그랗게 말린 컬링부(2)의 끝단부가 옆지(1)의 외부면과 접촉하고 있으므로 동그랗게 말린 컬링부(2)의 내측으로 열풍이 유입되지 못하게 되었고, 그로 말미암아 컬링부(2)의 외부면에 코팅된 비닐코팅층이 충분히 녹지 않아서 컬링부(2)를 성형완료한 뒤에 동그랗게 말은 컬링부(2)가 풀어지게 되는 불량이 발생하게 되었다.By the way, when forming the upper curling portion (2) as shown in the enlarged partial view of Figure 1 end of the round curling portion (2) is in contact with the outer surface of the side (1) curled curling portion (2) The hot air is not allowed to flow into the inner side, and the vinyl coating layer coated on the outer surface of the curling part 2 is not sufficiently melted, so that the curling part 2 rolled up after the curling part 2 is formed is released. There was a defect that was lost.

상기와 같이 컬링부(2)의 비닐코팅층이 충분히 녹지 않아 느슨하게 컬링부(2)가 형성된 상태에서 도 3과 같이 컬링부(2)를 납작하게 형성하고자 동그랗게 말린 컬링부(2)를 납작하게 눌렀을 때, 컬링부(2)의 비닐코팅층이 충분히 녹지 않았으므로 납작하게 눌린 부분에서 틈새(6)가 생겨 납작한 컬링부가 든든하게 접착되지 않게 되는 문제가 있었다.When the vinyl coating layer of the curling part 2 is not sufficiently melted as described above, the curled curling part 2 is flat pressed to form the curling part 2 flat as shown in FIG. 3 while the curling part 2 is loosely formed. At this time, since the vinyl coating layer of the curling part 2 is not sufficiently melted, there is a problem in that the gap 6 is formed in the flat pressed part and the flat curling part is not firmly bonded.

또한, 밑굽(7)의 경우에도 하향절곡부(3)를 감싸지게 절곡된 감쌈부(5)에 의해 3겹으로 접합되는 밑굽(7)의 내측으로 열풍이 유입되지 않으므로 위의 컬링부를 형성할 때 비닐코팅층이 충분이 녹지 않아 완벽한 접착이 이루어지지 않는 것과 동일한 문제가 발생하게 되었고, 이렇게 밑굽(7)이 든든하게 접착이 되지 않을 경우에는 종이컵(8)에 담겨지는 액체의 내용물이 새게 되는 문제를 발생시키게 되는 폐단을 지니고 있었다.In addition, even in the case of the heel 7, since the hot air does not flow into the inside of the heel 7 joined in three layers by the wrapping portion 5 bent to surround the downward bending portion 3, the curling portion may be formed. When the vinyl coating layer is not sufficiently melted, the same problem occurs that perfect adhesion is not achieved. If the heel 7 is not securely bonded, the problem of leaking the contents of the liquid contained in the paper cup 8 is prevented. Had the lungs generated.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 컬링부를 형성하게 되는 옆지의 상단부와, 밑굽을 형성하게 되는 옆지의 하단부에 다수개의 열기침투홈을 형성함으로서, 컬링부를 형성할 때와, 옆지의 하단부를 내측으로 절곡시켜 밑굽을 형성할 때에, 상기 다수의 열기침투홈으로 열풍이 들어가면서 옆지의 내면에 코팅된 비닐코팅층을 녹이게 되어 컬링부와 밑굽이 작은 압축하중으로도 성형 및 접착이 잘 되도록 하고, 종이컵 상단의 컬링부를 납작하게 형성하는 경우에 납작하게 형성되는 납작컬링부가 단단하게 접착될 수 있도록 하는 것을 기술적 과제로 한다.The present invention is to solve the above problems, by forming a plurality of hot penetrating grooves in the upper end of the side to form the curling portion, the lower side of the side to form the heel, when forming the curling portion, the lower end of the side When bent inward to form a heel, hot air enters the plurality of hot penetrating grooves to melt the coated vinyl coating layer on the inner surface of the side so that the curling portion and the heel are well formed and adhered even under a small compressive load. In the case of forming the curling part of the upper end of the paper cup flat, it is a technical problem to make the flat curling part formed flat.

상기의 목적을 달성하기 위한 본 발명은, 테이퍼관 형태로 형성된 옆지의 상단부에 외측으로 동그랗게 말린 컬링부가 형성되고, 외주연 전둘레가 하향 절곡되어 하향절곡부를 형성한 밑지가 옆지의 하단부 내측으로 삽입된 상태에서 옆지의 하단부를 내측으로 절곡하는 감쌈부로 하향절곡부를 감싸게 결합하여 밑굽을 형성하는 종이컵에 있어서, 상기 옆지의 상단부에 형성되는 컬링성형부의 상단부와, 옆지의 하단부에 형성되는 밑굽성형부의 하단부에 컬링성형부의 폭과 밑굽성형부의 폭보다 깊이가 낮은 다수개의 열기침투홈이 형성된 것을 특징으로 한다.The present invention for achieving the above object, the curled portion curled outwardly is formed in the upper end of the side formed in the tapered tube form, the outer periphery is bent downward to form a bottom bent into the bottom of the side In the paper cup to form a heel by wrapping the lower bent portion wrapped around the lower end of the side in the closed state to form a heel, the upper end of the curling molding formed on the upper end of the side, and the lower end of the heel forming formed on the lower end of the side It characterized in that a plurality of hot penetration penetrating grooves having a depth less than the width of the curling molding portion and the width of the heel molding portion.

도 4의 (가)(나)에서는 본 발명에 의한 옆지(1)의 각종 실시예를 나타내고 있는데, 먼저 옆지(1)의 상단부를 말아서 컬링부(2)를 형성할 부분을 컬링성형부(11)라 칭하고, 옆지(1)의 하단부를 내측으로 절곡하여 하향절곡부(3)를 감싸 결합하는 부분을 밑굽성형부(12)라 칭함을 밝혀둔다.In Figure 4 (a) (b) shows various embodiments of the side limb 1 according to the present invention, first curled the upper end of the side limb 1 to form a curling portion 2 to form a curling molded part 11 ), The lower end of the side edge (1) is bent inward to the part that surrounds the downward bent portion (3) to engage the foot molding portion (12).

본 발명의 요부가 되는 옆지(1)의 상단부에 형성되는 컬링성형부(11)의 상단부와, 옆지(1)의 하단부에 형성되는 밑굽성형부(12)의 하단부에 컬링성형부(11)의 폭과 밑굽성형부(12)의 폭보다 깊이가 낮은 다수개의 열기침투홈(9,10)이 형성된다.The upper end of the curling molded part 11 formed at the upper end of the side 1, which is the main part of the present invention, and the curling molded part 11 at the lower end of the heel forming part 12 formed at the lower end of the side 1. A plurality of hot penetrating grooves 9 and 10 having a width and a depth smaller than the width of the heel portion 12 are formed.

상기 열기침투홈(9,10)는 도 4의 (가)(나)에서 보는 바와 같이 파형으로 형성하거나, 다수의 펀칭된 구멍을 간격을 두고 형성할 수 있는 것이며, 도면에는 도시하지 않았으나 삼각홈 모양, 또는 반원홈모양, 사각홈모양 중 어느 하나의 모양을 선택하여 열기침투홈(9,10)을 간격을 두고 형성할 수 있다.The hot penetrating grooves 9 and 10 may be formed in a waveform as shown in (a) or (b) of FIG. 4, or may be formed at a plurality of punched holes at intervals. By selecting one of the shape, or semi-circular groove shape, the square groove shape can be formed at intervals of the hot penetration groove (9, 10).

그리고, 상기 열기침투홈(9)은 컬링성형부(11)에만 형성할 수 도 있고, 열기침투홈(10)을 밑굽성형부(12)에만 형성할 수 도 있으며, 위에서 언급한 바와 같이 각각의 열기침투홈(9,10)을 컬링성형부(11)와 밑굽성형부(12)에 모두 형성할 수 있는 것이다.In addition, the hot penetrating groove (9) may be formed only in the curling molding portion 11, the hot penetrating groove (10) may be formed only in the heel forming portion (12), as described above The hot penetrating grooves 9 and 10 may be formed in both the curling molded part 11 and the heel molded part 12.

상기와 같이 구성되어 있는 본 발명의 작용 관계를 도 4 내지 도 6을 참고하여 설명하면 다음과 같다.Referring to Figures 4 to 6 the operational relationship of the present invention configured as described above is as follows.

도 4의 (가)(나)에서 보는 바와 같이 옆지(1)의 컬링성형부(11)와 밑굽성형부(12)에 열기침투홈(9,10)을 형성한 옆지(1)를 테이퍼관 형태로 말은 뒤에 상측 컬링성형부(11)를 외측으로 말게 되면, 도 5 및 도 6에서 보는 바와 같이 컬링부(2)의 선단부가 옆지(1)의 컬링부(2)가 말리는 옆지(1)의 외부면에 접촉하게 되는데, 상기 컬링부(2)의 선단부에는 열기침투홈(9)이 형성되어 있음에 따라 컬링부(2)의 선단부와 컬링부(2)가 말리는 옆지(1)의 외부면 사이에 열풍이 들어갈 수 있는 구멍이 형성되게 된다.As shown in (a) and (b) of FIG. 4, the tapered pipe having the side edges 1 formed with the heat penetrating grooves 9 and 10 formed in the curling portion 11 and the heel portion 12 of the side edge 1. When the curling portion 11 is rolled outward, the leading edge of the curling portion 2 curls the curling portion 2 of the side 1 as shown in FIGS. 5 and 6. The outer surface of the curling part 2 is in contact with the opening part of the curling part 2 as the opening penetrating groove 9 is formed, and the curling part 2 of the side 1 of the curling part 2 is dried. Holes for entering hot air are formed between the outer surfaces.

상기와 같이 열기침투홈(9)에 의해 컬링부(2)에 형성되는 구멍으로 컬링부를 말아서 성형하고 열풍을 불어줄 때, 열기침투홈(9)에 의해 형성되는 구멍으로 열풍이 들어가게 되며, 이렇게 컬링부(2)의 내부로 들어가는 열풍이 컬링부(2)의 외부면에 코팅되어 있는 비닐코팅층을 녹여서 컬링부(2) 전체가 부드러워지며, 시간이 경과하여 녹았던 비닐코팅층이 굳어진 뒤에서 동그랗게 말린 상태에서 비닐코팅층이 녹았다가 굳어졌기 때문에 동그랗게 말린 상태를 그대로 유지하게 된다.As described above, when the curling part is rolled into a hole formed in the curling part 2 by the hot penetrating groove 9 and blows hot air, the hot air enters the hole formed by the hot penetrating groove 9. Hot air entering the interior of the curling section 2 melts the vinyl coating layer coated on the outer surface of the curling section 2, thereby softening the entire curling section 2, and drying it in a circular manner after the vinyl coating layer that has melted over time has hardened. Since the vinyl coating layer melts and hardens in a state, it maintains a circularly dried state.

그 다음에 도 3과 같이 컬링부(2)를 눌러서 납작한 컬링부를 형성하는 경우에는, 종이컵제조장치에서 컬링부를 말아서 형성하고 열풍을 불어넣은 뒤에는 곧바로 컬링부를 눌어 납작하게 하는데, 동그랗게 말은 컬링부에 열풍을 불어 넣어서 컬링부(2)의 비닐코팅층이 녹아있는 상태이므로, 납작한 컬링부가 녹은 비닐코팅층에 의해 견고하게 접착되어 납작한 컬링부를 든든하게 형성할 수 있게 되는 것이 다.Then, in the case of forming the flat curling part by pressing the curling part 2 as shown in FIG. Since the vinyl coating layer of the curling part 2 is melted by blowing hot air, the flat curling part is firmly adhered by the melted vinyl coating layer, thereby forming a flat curling part securely.

다음은 밑굽(7)을 형성할 때에 대한 설명인데, 이 경우에도 컬링부(2)를 형성할 때와 동일하게 하향절곡부(3)를 감싸는 감쌈부(5)의 하단부에 열기침투홈(10)이 형성되어서 그 열기침투홈(10)으로 열풍이 유입되어 감쌈부(5)에 코팅된 비닐코팅층과, 하향절곡부(3)에 코팅된 비닐코팅층이 녹으면서 하향절곡부(3)와 감쌈부(5)가 견고하게 접착되게 되어 든든한 밑굽(7)을 형성하게 되는 것이며, 그에 따라 종이컵에 담겨지는 액체의 내용물이 새지 않게 되는 것이다.The following is a description of when forming the heel (7), in this case also in the case of forming the curling portion (2) hot-opening grooves (10) at the lower end of the wrap section (5) surrounding the down bending portion (3) ) Is formed and the hot air flows into the hot penetrating groove 10, and the vinyl coating layer coated on the wrapping part 5 and the vinyl coating layer coated on the down bending part 3 melt together with the down bending part 3 and the winding. The ssam portion 5 is to be firmly bonded to form a firm heel (7), thereby the contents of the liquid contained in the paper cup will not leak.

위에서 각각의 열기침투홈(9,10)의 깊이가 옆지(1)의 상단부에 형성되는 컬링성형부(11)의 폭과, 옆지(1)의 하단부에 형성되는 밑굽성형부(12)의 폭보다 낮게 형성한 것은, 상기 각각의 열기침투홈(9,10)의 깊이가 컬링성형부(11)와 밑굽성형부(12)의 폭보다 높다면 컬링부(2)와 감쌈부(5)에 큰 구멍이 형성되어 외관이 좋지 못할 뿐만 아니라, 밑굽(7)의 경우 액체 내용물의 누수가 예견되기 때문인 것이다.The depth of each of the heat penetrating grooves 9 and 10 from above is the width of the curling molded part 11 formed at the upper end of the side 1, and the width of the heel molded part 12 formed at the lower end of the side 1. The lower portion is formed in the curling portion 2 and the wrapping portion 5 if the depth of each of the hot penetrating grooves 9 and 10 is higher than the width of the curling portion 11 and the heel portion 12. This is because a large hole is formed and not only the appearance is not good, but also in the case of the heel 7, leakage of the liquid contents is foreseen.

상기와 같이 본 발명의 종이컵용 옆지는, 컬링부를 형성하게 되는 옆지의 상단부와, 밑굽을 형성하게 되는 옆지의 하단부에 다수개의 열기침투홈을 형성함으로서, 컬링부를 형성할 때와, 옆지의 하단부를 내측으로 절곡시켜 밑굽을 형성할 때에, 상기 다수의 열기침투홈으로 열풍이 들어가면서 옆지의 내면에 코팅된 비닐코팅층을 녹이게 되어 컬링부와 밑굽이 작은 압축하중으로도 성형 및 접착이 잘 되도록 하는 효과와, 종이컵 상단의 컬링부를 납작하게 형성하는 경우에 납작하게 형성되는 납작컬링부가 단단하게 접착될 수 있게 하는 효과가 있는 것이다.The side paper for the paper cup of the present invention as described above, by forming a plurality of hot penetrating grooves in the upper end of the side forming the curling portion, and the lower end of the side forming the heel, when forming the curling portion, and the lower end of the side When bending to the inside to form the heel, hot air enters the plurality of hot penetrating grooves to melt the vinyl coating layer coated on the inner surface of the side so that the curling portion and the heel can be molded and adhered well under a small compression load.
