본 고안은 주로 학생이나 직장인들이 휴대할 수 있는 보온도시락의 구조를 개량하여 보온효과를 일층더 개선시킨 것이다.The present invention is to improve the warming effect by further improving the structure of the thermal insulation box that can be carried mainly by students or office workers.
종래 일반적으로 공지된 보온도시락은 통체를 내외 이중 통으로 형성한 것이나 이는 내외부 통체가 한몸체로 연결 용접되어 있어 내부통체에 내용물을 장입할시 내부통체의 자체 전도열이 외부통체로 쉽게 전도되어 밖으로 쉬 방출되기 때문에 보온 효율이 매우 저조한 단점이 있었다.Conventionally known heat retention time is that the cylinder is formed into a double cylinder inside and outside, but the inner and outer cylinders are connected and welded by one body, so when the contents are loaded into the inner cylinder, the conductive heat of the inner cylinder is easily conducted to the outer cylinder and is easily discharged to the outside. Because of the very low insulation efficiency was a disadvantage.
본 고안은 이와 같은 종래의 보온 도시락의 결점에 착안하여 장기간 실험을 통해 연구한 결과 내부통체의 열이 외부통체로 직접 전도될 수 없는 차단패킹을 개재한데 특징이 있다.The present invention is characterized by the fact that through the long-term experiments focused on the drawbacks of such a conventional thermal lunch box through the blocking packing that the heat of the inner cylinder can not be conducted directly to the outer cylinder.
본 고안의 구조는 내부통체의 입구부를 상하 서로 분할 상태로 만들어 완전히 분할 시키고 그 사이에 열전도 효율이 극히 낮은 단열고무패킹을 개재하여 내통의 열이 뚜껑쪽으로 전도되지 못하게 함과 동시에 뚜껑체의 내부에도 단열고무 패킹판을 부착하여 이중으로 열 전도를 차단시킨 것인 바 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The structure of the present invention divides the inlet part of the inner cylinder into the upper and lower parts so that it is completely divided and prevents the heat of the inner cylinder from conducting toward the lid through the insulation rubber packing with extremely low thermal conductivity. Attached to the insulating rubber packing plate is to block the heat conduction double, which will be described in detail based on the accompanying drawings as follows.
도시락 통체(1)상에 외뚜껑(2)이 씌워져 있고 외뚜껑(2)내부에 속뚜껑(6)을 내통(3)상부에 나합하여 밀폐시킨 통상의 것에 있어서의 내통(2) 상측입구부에 할절부(4)를 두어 상하를 완전히 분리시킨 후 이 할절부(4)에 단열고무 패킹(5)을 끼우고 분할된 내측부를 브라켓(10) (10')이 서로 맞물려 당겨지도록 조임볼트(9)를 대향으로 조여 고무패킹(5)이 협지되게 하되 속뚜껑(6) 저면에는 단열 패킹판(7)을 고정판(8)으로 고정시켜 속뚜껑(6)을 결합할시 패킹판(7)이 단열패킹(4)의 내주면에 상호 접합탄지 되도록 한 것이다.The inner lid (2) upper inlet part of the ordinary thing in which the outer lid (2) was covered on the lunch box cylinder (1), and the inner lid (6) was joined to the upper portion of the inner cylinder (3) inside the outer lid (2). After the upper and lower parts are completely separated by placing the cutout part 4 in the upper part, insert the insulating rubber packing 5 into the cutout part 4 and tighten the bolts so that the brackets 10, 10 'are engaged with each other and pulled together. 9) to face the rubber packing (5), but the inner lid (6) to the bottom of the insulating packing plate (7) by fixing the fixing plate (8) to combine the inner lid (6) packing plate (7) The inner circumferential surface of the heat insulation packing 4 is made to be bonded to each other.
이와 같이 된 본 고안은 다음과 같은 효과가 있다.The present invention thus obtained has the following effects.
종래의 보온도시락은 속뚜껑(6) 상면에 삽설한 단열 고무패킹(11) 하나에 의해 내통(3)의 열이 상면에서 용접가공에 의해 서로 한덩어리로 연결된 외부통체(1)에 그대로 전달되어 전도열에 의한 열손실이 많았으나 본 고안은 내통(3)의 입구부가 결여부(4)에 의해 분리되어 있고 이속에 단열패킹(5)이 끼워져 있어 속뚜껑(6)쪽과는 내통(3)이 서로 차단 및 단열상태에 있어서 내통(2)의 열이 밖으로 전도될 수 없는 것이다.Conventional heat retention time is transmitted to the outer cylinder (1), which is connected to the inner cylinder (3) by the heat treatment of the inner cylinder (3) in a mass by the welding process on the upper surface by a single insulating rubber packing (11) inserted into the upper surface of the inner lid (6) Although the heat loss caused by the conduction heat was large, the present invention has the inlet part of the inner cylinder (3) separated by the lacking part (4), and the heat-insulating packing (5) is fitted in the inner lid (6) and the inner cylinder (3). In this state of blocking and insulating each other, the heat of the inner cylinder 2 cannot be conducted outside.
또한 속뚜껑(6)의 저면에 부착한 패킹판(7)의 하주연 측이 전기한 단열패킹(5)에 압접되어 있으므로 속두껑(6)을 닫으면 이들 단열패킹(5)과 패킹판(7)이 강하게 밀착되어 내통(3)측의 열은 이들 패킹체(5) (7)에 의해 완전히 단열됨과 아울러 다시 상부측의 패킹(11)에 의해 이중으로 단열되므로 내부에 장입한 음식물의 보온 효과가 최상의 상태로 보존되는 것이다.In addition, since the lower circumferential side of the packing plate 7 attached to the bottom surface of the inner lid 6 is press-contacted to the above-described heat insulating packing 5, when the inner lid 6 is closed, these insulating packing 5 and the packing plate 7 are closed. ) Is tightly in contact with each other, so that the heat on the inner cylinder 3 side is completely insulated by these packing bodies 5 and 7 and double-insulated by the packing 11 on the upper side. Is best preserved.
따라서 본 고안은 도시락의 단열 차단장치가 이중으로 이루어지고 내통(3)이 단열패킹(5)에 의해 완전히 외통(1)과는 분리상태에 있어 도시락 및 보온식수통으로 매우 보온효과가 양효한 잇점이 있다.Therefore, the present invention has a double heat insulation blocking device of the lunch box, and the inner cylinder (3) is completely separated from the outer cylinder (1) by the heat insulation packing (5), the benefits of very good thermal insulation effect as a lunch box and a warm water bottle have.
