따라서, 본 발명의 단열용기(1)는 표면에 직접 다양한 인쇄표현이 가능하여 별도의 표지가 사용되지 않게 되는 장점을 나타내며, 표면에 미세한 요철면이 발생하므로 까칠한 질감이 향상되고, 용기 내부에 투입되는 고온의 취반수 열기가 장시간 차단되는 특징을 나타내는 것이다.Therefore, the heat insulation container 1 of the present invention shows the advantage that a separate label is not used because various printing expressions can be directly applied to the surface, and fine uneven surface is generated on the surface, so that the rough texture is improved and put into the container. It is to exhibit the feature that the hot cooking water is blocked for a long time.

본 발명을 적용함에 있어서 폴리스틸렌(PS)을 발포하여 소정의 두께를 갖는 발포체를 성형할 수 있으며, 인체에 무해한 합성수지라면 어떠한 소재를 적용하여도 가능할 것이다.In applying the present invention, it is possible to form a foam having a predetermined thickness by foaming polystyrene (PS), and any material may be applied as long as it is a synthetic resin harmless to the human body.

즉, 열가소성 수지로서 인체에 무해한 소재라면 어느 소재를 적용해도 무방하다.That is, as long as it is a material harmless to a human body as a thermoplastic resin, you may apply any material.

이러한 방법으로 제작되는 본 발명의 일회용 단열용기는, 첨부 도면 도 1과 도 2에 도시된 바와 같이, 보온원단(6)을 사발형태의 단열용기(1)로 성형하거나, 컵(1')으로 제작이 가능하다.Disposable heat insulating container of the present invention produced in this way, as shown in Figure 1 and 2 of the accompanying drawings, to form a thermal insulation fabric (6) into a bowl-shaped heat insulating container (1), or to a cup (1 '). Production is possible.

또한, 상기한 일반적으로 뜨거운 취반수가 투입되는 일회용 단열용기(1)뿐만 아니라, 아이스크림과 같이 보온을 필요로 하는 용기에도 적용될 수 있다.In addition, as well as the disposable heat insulation container (1) in which the hot cooking water is generally introduced, it can be applied to a container requiring heat insulation such as ice cream.

즉, 본원발명의 일회용 단열용기 제작에 사용되는 보온원단(6)은, 종이(3)의 일면에 폴리에틸렌 발포체(2)가 합체되어 있으므로, 이 폴리에틸렌 발포체(2)가 보온작용을 하여 아이스크림이 보온보관되는 것이다.That is, in the thermal insulation fabric 6 used for manufacturing the disposable insulation container of the present invention, since the polyethylene foam 2 is incorporated on one surface of the paper 3, the polyethylene foam 2 keeps warm and the ice cream is insulated. It is kept.

본 발명에 있어서, 폴리에틸렌 발포체(2)의 일면에만 코로나(corona) 처리를 하여 적용할 수 있다.In the present invention, only one surface of the polyethylene foam 2 can be applied by corona treatment.

폴리에틸렌 발포체(2)와 폴리에틸렌 코팅층(4)은 상호간에 열접착력이 좋으므로, 이들 접착면에 코로나 처리를 하지 않고 열 접착한 후, 외부로 노출된 폴리에틸렌 발포체의 표면만 코로나처리를 하여 일회용 단열용기를 제작할 수 있으며, 이러한 일면의 코로나 처리로 인한 특징은, 상기한 양면의 코로나 처리와 동일한 특징과 효과를 얻는다.Since the polyethylene foam 2 and the polyethylene coating layer 4 have good thermal adhesion between each other, they are heat-bonded to these adhesive surfaces without corona treatment, and then only the surface of the polyethylene foam exposed to the outside is subjected to corona treatment for a disposable insulation container. It can be produced, the characteristics due to this one-side corona treatment, obtains the same features and effects as the above-described corona treatment of both sides.
