Description

방열부를 구비한 이중 용기{DOUBLE VESSEL}Double container with heat dissipation part {DOUBLE VESSEL}

본 발명은 내지의 외측에 외지를 접합시켜 단열기능을 갖는 공간부를 형성할 수 있도록 한 이중 용기에 관한 것으로써, 특히 상단부에 컬링부가 형성된 외지를 원형으로 말을때 상단부에서의 주름과 같은 변형을 방지하면서 공간부의 열기를 외부로 원할하게 방출할 수 있도록 하여 전자레인지 이용과 같은 고온 가열시에도 안심하고 사용할 수 있도록 한 방열부를 구비한 이중 용기에 관한 것이다.The present invention relates to a double container capable of forming a space portion having an insulating function by bonding an outer paper to the outside of the inner paper, and in particular, when the outer paper having a curling portion formed on the upper portion is rolled into a circle, deformation such as a wrinkle at the upper end is prevented. The present invention relates to a double container provided with a heat dissipation unit that allows the heat of the space to be smoothly discharged to the outside while preventing it, so that it can be safely used even during high temperature heating such as microwave use.

최근에는 단열을 위한 이중 구조의 종이 용기들이 개발되고 있으며, 그 일 예의 이중용기가 실용신안등록 제20-0344484호에 개시되고 도 1에 도시된 바와 같이, 내용물을 수용하는 수용공간을 형성하는 내지(11)와, 내지(11)의 외측에 일정간격을 두고 내지를 감싸는 외지(12)로 이루어지고, 내지(11)와 외지(12) 사이의 공간이 외부공간과 연결되도록 외지(12)에 적어도 하나의 방열구멍(12a)이 형성된 구조를 갖는다.Recently, paper containers of a double structure for insulation have been developed, and an example of the double container is disclosed in Utility Model Registration No. 20-0344484, and as shown in FIG. 1, a space for receiving contents is formed. (11), consisting of an outer area 12 surrounding the inner area at a certain interval on the outside of the inner area (11), and the outer area 12 so that the space between the inner area (11) and the outer area (12) is connected to the outer space. It has a structure in which at least one heat dissipation hole 12a is formed.

외지(12)의 상단부는 제 1컬링부(11c)사이에 끼워지고 외지(12)의 하단부에는 제 2컬링부(12b)를 형성하여 내지(11)의 측면 하단부에 부착되는 구조를 갖는다.The upper end of the outer paper 12 is sandwiched between the first curling portions 11c, and a second curling portion 12b is formed at the lower end of the outer paper 12 to be attached to the lower side of the side of the toe 11.

그런데, 상기와 이중 용기는 방열구멍(12a)이 외지(12)의 하부측에 형성됨으로써, 열기의 특성상 상승기류의 영향으로 열기가 외부로 원할하게 배출되지 못하는 문제점이 있다.By the way, since the heat dissipation hole 12a is formed on the lower side of the outer paper 12, the heat dissipation hole 12a and the double container have a problem in that the heat cannot be smoothly discharged to the outside due to the influence of the rising air flow due to the nature of the heat.

특히, 도 1에 도시된 바와 같이, 외지(12)의 상단부가 제1컬링부(11c)사이에 끼워지는 구조에 있어서는 외지의 상단부에 방열공의 형성이 어렵고, 용기의 상단부를 파지하여 음용할때 용기 내부의 내용물로부터 열이 직접적으로 사용자의 손가락으로 전달되어 파지가 불편한 문제점이 있다. In particular, as shown in Fig. 1, in the structure in which the upper end of the outer paper 12 is sandwiched between the first curling parts 11c, it is difficult to form a heat dissipation hole at the upper end of the outer paper, and the upper end of the container is gripped to drink In this case, heat is transferred directly from the contents inside the container to the user's fingers, making it inconvenient to grip.

또한, 한국공개특허 10-2016-0069068호에 개시되고 도 2에 도시된 바와 같은 이중 종이컵의 경우, 내지(110)와 외지(130) 사이의 공간부(140)를 더 확보하기 위하여 외지(130)의 상단부에 컬링으로 제1지지부(131)를 형성하지만 외지(130)를 통형으로 말을때 외지(130)의 제1지지부(131)로 인하여 상단부에서 쭈글쭈글해지는 주름이 형성되는 문제점이 있다.In addition, in the case of a double paper cup as disclosed in Korean Patent Application Laid-Open No. 10-2016-0069068 and shown in FIG. 2, in order to further secure the space 140 between the to 110 and the outer paper 130, the outer paper 130 ), the first support part 131 is formed by curling at the upper end, but there is a problem that wrinkles are formed in the upper part due to the first support part 131 of the outer part 130 when the outer part 130 is rolled into a cylindrical shape. .

To be.

본 발명 실시예의 이중 용기(200)를 나타낸 도 3, 도 4 및 도 8을 참조하면, 이는 상부에 제1컬링부(221)가 형성된 통형의 내지(210)와, 상기 내지(210)의 하단부에 결합되는 밑지(230)와, 상기 내지(210)와의 사이에 공간부(240)가 형성되도록 상기 내지(210)의 외측에 결합되며 상기 공간부(240)의 공기가 배기되는 방열부(222b)가 형성된 외지(220)로 이루어진다.Referring to FIGS. 3, 4 and 8 showing the double container 200 of the present invention embodiment, this is a cylindrical to 210 having a first curling part 221 formed thereon, and a lower end of the to 210 A heat dissipation part (222b) which is coupled to the outside of the to (210) so that the base (230) coupled to the base (230) and the space (240) is formed between the to (210) and exhaust air of the space (240) ) Consists of the outer paper 220 is formed.

상기 외지(220)의 상단부와 하단부에는 내측으로 말아지거나 접어진 제2컬링부(224)와 제3컬링부(225)가 형성되어서, 상기 공간부(240)를 확보할 수 있도록 하였다.A second curling portion 224 and a third curling portion 225, which are rolled or folded inwardly, are formed at the upper and lower portions of the outer paper 220, so that the space portion 240 can be secured.

특히, 도 4 내지 도 7을 참조하면, 상기 외지(220)의 제2컬링부(224)는 단부가 개방되도록 제1깊이로 절취된 복수의 제1절취홈(221)과, 상기 제1깊이보다 상대적으로 더 깊은 제2깊이로 상기 상단 가장자리가 개방된 적어도 하나의 제2절취홈(222)이 형성되어 있다.In particular, referring to FIGS. 4 to 7, the second curling portion 224 of the outer paper 220 includes a plurality of first cutting grooves 221 cut to a first depth so that the end portion is opened, and the first depth. At least one second cut-out groove 222 with an open top edge is formed at a relatively deeper second depth.

상기와 같은 구성의 외지(220)는 상기 제1절취홈(221) 전부를 포함하고 상기 제2절취홈(222)의 일부분(주름방지부:222a)이 포함되도록 접이선(223)을 따라서 상기 상단 가장자리를 접어서 제2컬링부(224)를 형성하게 되며, 상기 접혀진 부분이 상기 내지(210)의 외측면에 접착되게 된다.The outer paper 220 having the above configuration includes all of the first cutting groove 221 and along the fold line 223 so that a part of the second cutting groove 222 (wrinkle prevention part: 222a) is included. The upper edge is folded to form the second curling portion 224, and the folded portion is adhered to the outer surface of the to 210.

이 경우 상기 제2절취홈(222)의 나머지 일부분(방열부;222b)을 통하여 상기 공간부(240)의 공기가 배출될 수 있게 되며, 도 3 및 도 6에 도시된 바와 같이 상기 방열부(222b)는 외부에 노출되게 형성된다.In this case, the air in the space part 240 can be discharged through the remaining part of the second cutout groove 222 (heating part 222b), and as shown in FIGS. 3 and 6, the heat dissipation part ( 222b) is formed to be exposed to the outside.

상기 제2절취홈(222)은 주름방지부(222a)와 방열부(222b)로 이루어지며, 상기 주름방지부(222a)는 상기 제1절취홈(221)과 동일 형상 및 동일 기능을 가지며 외지(220)를 원형으로 말았을때 상단부 가장자리에서의 주름발생을 방지할 수 있도록 한다.The second cutting groove 222 is made of a wrinkle prevention portion (222a) and a heat dissipation portion (222b), the wrinkle prevention portion (222a) has the same shape and the same function as the first cutting groove (221) When (220) is rolled in a circular shape, it is possible to prevent the occurrence of wrinkles at the edge of the upper end.

상기 외지(220) 상단에서의 주름형성 방지와 열기 배출을 위한 제1절취홈(221)과 제2절취홈(222)은 하나의 금형으로 한번의 펀칭작업으로 형성이 가능하므로 제작을 간편하게 한다.The first cut-out groove 221 and the second cut-out groove 222 for preventing wrinkle formation at the top of the outer paper 220 and for discharging hot air can be formed by one punching operation with a single mold, thus simplifying manufacturing.

한편, 도 7을 참조하면, 상기 제2절취홈(222)의 하단부로부터 횡방향으로 연장된 확장홈(222c)을 형성하여서, 열기의 배출이 보다 원할하게 할 수도 있다.On the other hand, referring to FIG. 7, by forming an expansion groove 222c extending in the transverse direction from the lower end of the second cut-out groove 222, the discharge of heat may be more smooth.

상술한 바와 같은 구성의 이중 용기는 외지(220)의 상,하단부에 제2컬링부(224)와 제3컬링부(225)를 형성하여서 내지(210)와 외지(220) 사이에 공간부(240)를 확보함과 아울러 제2컬링부(224)에서의 주름을 방지하고 공간부(240)의 열기가 수월하게 배출될 수 있도록 한다.The double container of the configuration as described above is formed by forming the second curling portion 224 and the third curling portion 225 on the upper and lower ends of the outer paper 220 to form a space between the to 210 and the outer paper 220 ( In addition to securing 240), wrinkles in the second curling part 224 are prevented and the heat of the space part 240 can be easily discharged.

즉, 본 발명 실시예의 이중 용기는 상기 제2절취홈(222)의 방열부(222b)를 주름방지용 제1절취홈(221)의 제작과 함께 제작을 가능하게 하여 외지(220)의 제작을 간편하게 하면서, 동시에 방열부(222b)를 외지(220)의 상단부에 형성함으로써 열기의 상승기류 특성으로 열기가 외부로 원할하게 배출되게 한다.That is, the double container according to the present invention enables the manufacture of the heat dissipation part 222b of the second cutout groove 222 together with the fabrication of the first cutout groove 221 for anti-wrinkle, thereby simplifying the production of the outer paper 220 At the same time, by forming the heat dissipation part 222b on the upper end of the outer paper 220, the heat is smoothly discharged to the outside due to the rising airflow characteristic of the heat.
