본 발명은 발열팩용 포장지에 관한 것으로서, 상세하게는 PP 부직포와 PET 부직포를 접합하여 포장지를 제조하고, 내부에 발열체를 충진한 다음 테두리를 접합하여 발열팩을 제조함으로써 통기와 물의 유통이 원활하여 요구하는 발열 성능을 구현하며, 발열체가 외부로 배출되는 것을 막아 발열팩이 오염되는 것을 방지하도록 하는 이중 부직포 구조의 발열팩용 포장지에 관한 것이다.More particularly, the present invention relates to a packaging sheet for a heat-generating pack, and more particularly, to a packaging sheet for a heat-generating pack, in which a packaging paper is manufactured by bonding a PP nonwoven fabric and a PET nonwoven fabric, filling a heating element therein, The present invention relates to a wrapping paper for a heat-generating pack having a double-layered nonwoven fabric structure, which can prevent a heat-generating element from being discharged to the outside and prevent the heat-generating pack from being contaminated.

식생활 문화의 발달과 급격한 산업화로 각종 레토르트 포장식품 및 휴대용 인스턴트식품이 다양하게 개발되고 또한 사용되고 있으며, 최근에는 여러 가지 야외 활동이 활발히 성행하면서 이들의 사용이 급격하게 증가하고 있는 추세이다. 이러한 각종 레토르트 포장식품 및 휴대용 인스턴트식품은 냉장 보관되거나 간단한 처리만으로 먹을 수 있도록 가공되어, 별도의 취사도구를 필요로 하거나 고온의 물을 필요로 하는 문제가 있다.Various retort packaged foods and portable instant foods have been developed and used variously due to the development of the eating habits culture and rapid industrialization. Recently, various outdoor activities have been actively used and their use is increasing rapidly. These retort packaged foods and portable instant foods are processed to be eaten by being stored in a refrigerator or by a simple process, requiring separate cooking utensils or requiring high-temperature water.

특히, 군사적인 목적상의 훈련이나 실제 상황에 있어서 화기를 이용한 취사행위가 거의 불가능하므로 각종 레토르트 포장식품 및 휴대용 인스턴트식품을 사용하고 있지만 상기와 같은 문제점으로 인하여 적당한 식사를 할 수 없어 전력에 큰 차질을 빚는 경우도 있다.Particularly, since it is practically impossible to train in a military purpose or cook in a real situation using firearms, various retort packaged foods and portable instant foods are used. However, due to the above problems, it is impossible to eat properly, In some cases,

종래 발열체들은 몇 가지 금속산화물이나 금속염으로 구성되어 있다. 일예로 본 출원인에 의해 출원되어 등록된 국내 특허등록공보 10-0804257호에 개시된 바와 같이 산화칼슘과, 탄산칼슘과, 수산화나트륨과, 탄산나트륨 및 알루미늄을 혼합하여 발열체를 제조한다.Conventional heating elements consist of several metal oxides or metal salts. For example, a heating element is prepared by mixing calcium oxide, calcium carbonate, sodium hydroxide, sodium carbonate and aluminum, as disclosed in Korean Patent Registration No. 10-0804257 filed and registered by the present applicant.

한편, 이러한 발열체는 통상 국내 특허등록공보 10-1277378호, 국내 실용신안공개공보 20-1998-0019113호와 같이 부직포와 같은 물과 공기가 투과되는 포장지 내에 투입된다.On the other hand, such a heating element is usually put into a wrapping paper such as a nonwoven fabric which is permeable to water and air as disclosed in Korean Patent Registration No. 10-1277378 and Korean Utility Model Laid-Open No. 20-1998-0019113.

그리고, 선택적으로 발열체가 충진된 포장지를 밀폐 포장지에 넣어져 공기와 물의 접촉을 차단한 상태로 유통 보관한다.The wrapping paper, optionally filled with a heating element, is placed in a sealed wrapping paper and stored in a state in which contact between air and water is blocked.

그러나, 이러한 종래의 포장지는 단순히 부직포로 이루어져 있기 때문에 입자가 불균일한 발열체가 부직포를 통해 배출되고, 부직포의 표면에 묻어 부직포를 오염시키는 등의 문제점이 있다.However, since such a conventional wrapping paper is simply made of a nonwoven fabric, there is a problem that a non-uniform heating element is discharged through the nonwoven fabric and is buried on the surface of the nonwoven fabric to contaminate the nonwoven fabric.

이하, 본 발명에 따른 이중 부직포 구조의 발열팩용 포장지를 이용한 발열팩의 제조 방법을 설명하면 다음과 같다.Hereinafter, a method of manufacturing a heat generating pack using a wrapping paper for a heat generating pack having a double nonwoven structure according to the present invention will be described.

먼저, PP 부직포(10)와, PET 부직포(20)를 초음파 접합하여 합지시켜 본 발명인 이중 부직포 구조의 발열팩용 포장지(1)를 제조한 후 이를 롤 형태로 말아서 보관한다. 이때, 초음파로 전면을 모두 접합하는 것이 아니고, 부분적으로 접합시킨다.First, the PP nonwoven fabric 10 and the PET nonwoven fabric 20 are joined together by ultrasonic bonding to produce a wrapping paper 1 for a heat-generating pack having a double-layer nonwoven fabric structure of the present invention, which is rolled and stored in a roll form. At this time, not all the front surfaces are bonded together by ultrasonic waves, but are partially bonded.

그리고, 본 발명인 이중 부직포 구조의 발열팩용 포장지(1)를 발열체 충진 설비에 거치한 상태에서 포장지(1)를 이동시키면서 반으로 접고, 측면 테두리와 저면 테두리를 초음파 접합하되, 접합 패턴(40)이 형성되도록 한 다음 발열체를 충진하고, 하방향으로 이동시켜 상단 테두리를 초음파 접합하되, 접합 패턴(40)이 형성되도록 한다. 이때, 상단 테두리와 위에 이웃하는 포장지의 하단 테두리와 동시에 접합되는 것이 바람직하다.The wrapping paper 1 is folded in half while the wrapping paper 1 with the double-layer nonwoven fabric structure of the present invention is mounted on the heating element filling apparatus, and the side edges and the bottom surface of the wrapping paper 1 are ultrasonically bonded. And then the heating element is filled and moved in the downward direction to ultrasonically join the upper edge, so that the bonding pattern 40 is formed. At this time, it is preferable that the upper edge and the lower edge of the wrapping paper adjacent to the upper edge are simultaneously joined.

계속해서, 포장지(1)가 이동되어 상단 테두리와 위에 이웃하는 포장지의 하단 테두리의 중간 부분이 컷팅되어 낙하된다.Subsequently, the wrapping paper 1 is moved, and the upper edge and the middle portion of the lower edge of the wrapping paper adjacent to the upper end are cut and dropped.

그리고, 발열체(30)가 충진된 이중 부직포 구조의 발열팩용 포장지(1)는 다시 별도의 밀폐 포장지(미도시)에 넣어져 공기와 수분이 차단되도록 포장된다.The wrapping paper 1 for a heat-generating pack having a double-layered nonwoven fabric and filled with a heating element 30 is again packed in a separate sealed wrapping paper (not shown) to block air and moisture.

본 발명은 다양하게 변형될 수 있고 여러 가지 형태를 취할 수 있으며 상기 발명의 상세한 설명에서는 그에 따른 특별한 실시 예에 대해서만 기술하였다. 하지만 본 발명은 상세한 설명에서 언급되는 특별한 형태로 한정되는 것이 아닌 것으로 이해되어야 하며, 오히려 첨부된 청구범위에 의해 정의되는 본 발명의 정신과 범위 내에 있는 모든 변형물과 균등물 및 대체물을 포함하는 것으로 이해되어야 한다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood, however, that the invention is not to be limited to the specific forms thereof, which are to be considered as being limited to the specific embodiments, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. .

본 발명은 음식을 가열하는 발열팩 뿐만 아니라 손난로 등에도 적용할 수 있다.The present invention can be applied not only to a heat-generating pack for heating food, but also to a hand-warmer.
