Abstract

PURPOSE: A vacuum lunch-box is provided to improve a warmth keeping effect, to prevent food's taste from being deteriorated and to avoid food's weight from being increased, by keeping the foods charged in a box to a vacuum state. CONSTITUTION: The vacuum lunch-box includes a box(100) whose upper portion is opened and a cover(200) for tightly closing an opened part(111) of the box. An external panel(110) forms the external portion of the box. An internal panel(120) is coupled with a predetermined space to the external panel to have a closed section(130) with the external panel. A separate material(140) for keeping warmth is filled in the closed section. Therefore, a warmth keeping effect of the lunch-box is maximized.

Description

보온 도시락{Thermos lunch box}Thermal lunch box {Thermos lunch box}

본 발명은 보온 도시락에 관한 것으로서, 더욱더 상세하게는 함체에 보관중인 밥이나 반찬등과 같은 내용물이 식지 않도록 보다 효율적으로 보온되도록 하는 보온 도시락에 관한 것이다.The present invention relates to an insulated lunch box, and more particularly, to an insulated lunch box to more efficiently insulate the contents such as rice or side dishes stored in the housing to prevent cooling.

일반적으로 도시락은 학생 및 직장인들이 식사를 위해 밥과 반찬을 휴대할수 있도록 하는 용기의 일종이다.Lunch boxes are generally a type of container that allows students and workers to carry rice and side dishes for meals.

최근, 예로서 학생의 경우에는 점심은 물론, 늦은 야간수업을 위해 저녁용 식사도 함께 준비하고 있는 실정이다.Recently, for example, a student is preparing a dinner for a late night class as well as lunch.

도시락의 구조는 상부가 개구되어 형성된 함체와, 상기 함체의 개구부를 말폐시키는 뚜껑체로 이루어져 그 내부로 밥이나 반찬등을 채워지게 하는 것이다.The structure of the lunch box consists of a housing formed by opening the upper portion, and a lid body for closing the opening of the enclosure to fill the inside with rice or side dishes.

그러나 이러한 종래 도시락은 함체에 담겨진 밥이나 반찬등과 같은 내용물이 장시간 경과되는 경우에는 내용물이 차갑게 식게 됨으로서 맛이 저하됨은 물론, 섭취의욕을 저하시키는 문제점이 있었다.However, such a conventional lunch box has a problem in that the contents are cooled down when the contents such as rice or side dishes contained in the housing are cooled for a long time, thereby lowering the taste and lowering intake.

한편, 종래에도 상기와 같은 문제점을 해결하기 위해 도시락의 외측을 감싸는 별도의 보온재로 제작된 보온통을 제작하여 사용하고 있다.On the other hand, conventionally, in order to solve the above problems, a thermos made of a separate heat insulating material surrounding the outside of the lunch box is manufactured and used.

그러나 이러한 종래의 보온 수단에 의하면 별도의 보온통을 제작하여야 함으로서, 도시락을 제조시 제작단가가 상승되고, 도시락의 상품적 품위가 저하됨은 물론, 도시락 전체의 중량이 증가되어 학생 및 직장인들로 하여금 그 사용이 널리 이용되지 않게 되는 문제점이 있었다.However, according to the conventional thermal insulation means to manufacture a separate thermal insulation container, the manufacturing cost is increased when manufacturing the lunch box, the product quality of the lunch box is lowered, as well as the weight of the entire lunch box increases students and office workers There was a problem that the use is not widely used.

또한 종래에는 보온 효과가 양호하지 못하여 소정의 시간이 경과된 후에는 보온재의 존재와 무관하게 음식이 차갑게 식게 되는 등의 폐단이 있었다.In addition, conventionally, the thermal insulation effect is not good, and after a predetermined time has elapsed, the food has cooled down irrespective of the existence of the thermal insulation material.

본 발명의 목적은 상기 종래와 같은 문제점 및 폐단을 해소하기 위해, 상부가 개구되어 형성된 함체와, 상기 함체의 개구부를 밀폐시키는 뚜껑체로 구성되는것에 있어서, 상기 함체가 외측부를 형성하는 외측판넬과, 상기 외측판넬에 소정의 간격을 두고 폐단면으로 결합되는 내측판넬로 구성하여, 대기와 진공으로 함체에 보관중인 밥이나 반찬등과 같은 내용물이 대기와 진공으로 차단되므로 보온효과가 향상되게 됨으로서, 음식맛이 저하되지 않게 됨은 물론, 그 중량이 증가되지 않게되어 제품의 사용성이 향상되도록 하는 보온 도시락을 제공하는 데 있다.An object of the present invention, in order to solve the problems and the closed end as in the prior art, the upper body is formed of an opening, the lid body for sealing the opening of the housing, the outer panel forming the outer portion, and Consists of the inner panel coupled to the closed end face at a predetermined interval to the outer panel, the contents such as rice or side dishes stored in the enclosure by the atmosphere and vacuum is blocked by the atmosphere and vacuum, thereby improving the warming effect, food The taste is not reduced, of course, the weight is not increased to provide an insulated lunch box to improve the usability of the product.

이하 첨부된 도면에 의하여 본 발명의 그 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

본 발명의 보온 도시락은 도 1과 도 2에 도시하고 있는 바와 같이, 상부가 개구되어 형성된 함체(100)와, 상기 함체(100)의 개구부(111)를 밀폐시키는 뚜껑체(200)로 구성되는 것은 종래와 같다. 단, 본 발명은 상기 함체(100)가 외측부를 형성하는 외측판넬(110)과, 상기 외측판넬(110)에 소정의 간격을 두고 폐단면(130)으로 결합되는 내측판넬(120)로 구성됨을 그 기술적 구성상의 기본 특징으로 한다.1 and 2, the thermal insulation lunch box of the present invention comprises an enclosure 100 formed by opening the upper portion, and a lid 200 for sealing the opening 111 of the enclosure 100. It is the same as before. However, the present invention is composed of the outer panel 110, the inner panel 120 is coupled to the closed end surface 130 at a predetermined interval to the outer panel 110, the housing 100 forms an outer portion. It is the basic characteristic in technical configuration.

이와 같이 구성되는 본 발명은 함체(100)의 내측판넬(120)에 밥이나 반찬등과 같은 음식물을 담은 상태에서 함체(100)의 개구부(111)가 폐쇄되도록 뚜껑체(200)를 결합시키면, 상기 함체(100)의 내측판넬(120)과 외측판넬(110) 사이에 형성된 폐단면(130)에 의해 외부와 열전달이 차단되는 진공상태가 유지 됨으로서 열손실이 차단된다.The present invention configured as described above is coupled to the lid 200 to close the opening 111 of the housing 100 in a state containing food such as rice or side dishes in the inner panel 120 of the housing 100, Heat loss is blocked by maintaining a vacuum state in which heat and heat transfer are blocked by the closed end surface 130 formed between the inner panel 120 and the outer panel 110 of the enclosure 100.

따라서, 음식물의 보온 효과가 우수하게 되는 것이다.Therefore, the thermal insulation effect of food becomes excellent.

또한, 상기 폐단면(130)에는 도 2에 도시하고 있는 바와 같이, 별도의 보온재(140)를 충진시켜, 보온효과가 더욱 극대화 되도록 하여도 무방함을 밝혀 둔다.In addition, as shown in FIG. 2, the closed end surface 130 is filled with a separate thermal insulation material 140 to reveal that the thermal insulation effect may be further maximized.

따라서 이러한 본 발명은 대기와 진공으로 함체에 보관중인 밥이나 반찬등과 같은 내용물이 대기와 진공으로 차단되므로 보온효과가 향상되게 됨으로서, 음식맛이 저하되지 않게 됨은 물론, 그 중량이 증가되지 않게되어 제품의 사용성이 향상되도록 하는 효과가 있다.Therefore, the present invention is such that the contents such as rice or side dishes stored in the enclosure by the air and vacuum is blocked by the air and vacuum, so that the heat retention effect is improved, the food taste is not lowered, of course, the weight is not increased There is an effect to improve the usability of the product.
