Abstract

The present invention relates to a seal for a container provided with holes for easily inserting a straw and to a method for manufacturing same, and the seal for the container provided with the holes for inserting the straw according to the present invention is a high-frequency induction heating seal, which seals the container so as to be airtight, comprising: a surface layer comprising a material without heat sealing properties positioned at the upper end portion of the container seal; a laminate layer which is laminated with a thermoplastic resin having a consistent thickness or a polyolefin foaming agent and provided under the surface layer; a heat generation layer comprising aluminum foil, which is provided below the laminate layer, for generating heat when subject to high-frequency induction heating; and a heat sealing plastic resin or an adhesive agent under the heat generation layer, wherein seal adhering layers which adhere to the container are sequentially laminated to form a laminate structure, and wherein the lower portion of the laminate layer is adhered to the upper portion of the heat generation layer through a resin adhering layer, so that the straw can be used by inserting into holes which are punched on the surface layer and the laminate layer with a specific gap therebetween. The seal for the container provided with the holes for inserting the straw and the method for manufacturing same, comprised as described above according to the present invention, creates a specific layered structure and an upper layer hole for inserting the straw thereby allowing easy consumption of content by easily inserting a common straw. As a result, the advantage of preventing hygienic problems is provided by not requiring peeling the seal or touching an opening of the container with the hands, thereby eliminating the concern of introducing foreign substances to the opening of the container. Also, the seal for the container having these superior effects can be effectively provided through an easier method, thereby resolving existing problems described above. 상기와 같이 구성되는 본 발명의 빨대 삽입용 홀이 형성된 용기의 봉합체 및 그 제조방법은 특정한 층 구조와 상층 빨대 삽입용 홀을 형성하므로 통상적인 빨대를 용이하게 꽂아 내용물을 손쉽게 섭취할 수 있게 하고, 따라서 봉합체를 박리할 필요가 없어 용기의 입구에 손이 접촉되지 않게 하여 용기의 입구에 이물질이 묻을 우려가 없어 위생상의 문제가 발생하지 않는 효과가 있을 뿐 아니라, 이렇게 우수한 작용효과를 가지는 용기의 봉합체를 보다 용이한 방법으로 효과적으로 제공하므로 상기한 종래의 문제점을 해결한다.

Description

빨대 삽입용 홀이 형성된 용기의 봉합체 및 그 제조방법Suture of container with hole for inserting straw and its manufacturing method
본 발명은 빨대 삽입이 용이한 홀이 형성된 용기의 봉합체 및 그 제조방법에 대한 것이다. 보다 상세하게는, 본 발명은 봉합체의 상층 중앙에 통상의 빨대(straw)로 손쉽게 뚫을 수 있는 구조를 형성하여 이를 통해 용이하게 빨대를 꽂아서 사용할 수 있는 빨대 삽입용 홀이 일정한 사이즈로 형성된 인덕션 유도가열 봉합체와 이러한 특성을 갖는 봉합체를 보다 용이하게 제조할 수 있는 방법에 관한 것이다.The present invention relates to a suture of a container in which a hole is easily inserted into a straw, and a method of manufacturing the same. More specifically, the present invention forms a structure that can be easily punctured with a common straw in the center of the upper layer of the suture, through which the straw insertion hole that can be easily plugged into the straw induction induction formed in a certain size The present invention relates to a heat sealant and a method for more easily manufacturing a seal having such characteristics.
일반적인 우유나 의약품 등과 같이 기밀성을 요하는 제품은 플라스틱 또는 유리와 같은 재질의 용기에 포장되어 기밀성을 보장하기 위해 용기의 입구를 합성수지로 제조된 필름지의 형상으로 된 봉합체(이하, "봉합체"라 지칭한다)로 밀봉한다. 이러한 봉합체는 우유나 의약품 등이 포장되는 플라스틱이나 유리병과 같이 다양한 종류의 소재로 이루어진 용기의 입구를 기밀하게 봉합하여 액상이나 습기가 많은 물질 또는 건조한 분말가루 같은 제품이 용기 밖으로 새어 나오거나 외부의 공기가 용기내로 흡수되지 않도록 하는 작용을 한다.Products that require airtightness, such as general milk or pharmaceutical products, are packaged in plastic or glass-like containers and sealed at the entrance of the container in the form of film paper made of synthetic resin (hereinafter, "sealed"). Seals). These seals hermetically seal the openings of containers made of various types of materials, such as plastic or glass bottles in which milk or pharmaceutical products are packaged, so that liquids, moist substances, or dry powders can leak out of the containers or It acts to prevent air from being absorbed into the container.
종래에는 제품이 포장된 용기의 기밀성을 장기간 확실하게 유지하기 위하여, 용기의 입구와 봉합체가 접합되는 부분을 전면적으로 강하게 접착시켜 밀봉은 확실하게 잘 되지만 내용물을 꺼내고자 할 때에는 어린이나 노약자가 상기 봉합체를 박리하기가 어렵고, 더욱이 타인이 봉합체의 박리를 도와 주어도 내용물을 제대로 섭취를 못하고 흘리는 경우가 많을 뿐만 아니라, 박리를 위한 틈을 만들기 위해 손이나 가위와 같은 도구를 사용하여야 하므로 손이나 도구가 용기의 입구와 접촉되어 위생상의 문제점과 안전상의 문제점이 있다.Conventionally, in order to maintain the airtightness of a container in which a product is packaged for a long time, the entire surface of the container and the seam where the seal is bonded is strongly adhered to ensure a good seal, but when the user wants to take out the contents, a child or an elderly person may use the seal. It is difficult to peel off the sieve, and moreover, even if others help to remove the sutures, the contents are not easily ingested and spilled. Also, tools such as hands or scissors must be used to make a gap for peeling. Is in contact with the inlet of the container there are hygiene and safety problems.
상기와 같은 문제점을 해결하기 위하여 몇 가지 방안들이 제시되었는데, 그 일예로는 봉합체의 테두리부에 파지부를 형성하는 구성이 제안되었으나, 이러한 구성은 그 제조공정 및 비용상의 문제점과 파지부가 작아 봉합체를 개봉하기가 힘들다는 사용상의 문제점이 있다. 이러한 문제점을 해결하기 위한 대안으로 봉합체에 손잡이부를 작게 달아서 사용하는 방법이 제안되었다. 이러한 구조는 본 출원인에 의해 출원되어 등록된 대한민국등록특허 제10-0711073호에 개시되어 있다. 상기 등록특허에서는, "개봉이 용이하도록 봉합체의 상단면에 개봉꼭지(Tap)을 형성시켜 상기 개봉꼭지(Tap)를 잡고 손쉽게 용기로부터 봉합체를 떼어 낼 수 있도록 된 용기의 봉합체에 있어서, 상기 용기의 봉합체 상단부에 위치하여 열 접착성이 없는 재료를 포함하는 표면층; 상기 표면층에 적절한 두께로 얇은 열가소성 수지가 라미네이트된 열접착 수지층; 상기 열접착 수지층 하단에 접착되어 있는 열가소성 수지 또는 접착제로 된 접착층; 상기 접착층과 접착되어 알루미늄 호일이나 플라스틱 필름 등으로 된 중간기재층; 상기 중간기재층 하단에 접착되어 열접착성 가소성 수지 또는 점착제를 포함하는 것으로, 용기에 접착되는 봉합접착층;으로 구성되어 있는 개봉꼭지가 부착된 용기 봉합체"가 개시되어 있으며, 대한민국 특허공개공보 제2010-0040286호는 식료품의 용기용 밀봉재를 개시하고 있다.Several methods have been proposed to solve the above problems, but as an example, a configuration for forming a gripping portion at the edge of the encapsulation body has been proposed, but such a configuration has a problem in the manufacturing process and cost and the gripping portion is small. There is a problem in use that it is difficult to open the sieve. As an alternative to solve this problem, a method of using a small handle portion on the suture has been proposed. Such a structure is disclosed in Korean Patent No. 10-0711073 filed and registered by the present applicant. In the registered patent, "In the sealing body of the container that is formed to open the tap (Tap) on the upper end surface of the sealing body to facilitate the opening and holding the opening tap (Tap) to easily remove the sealing body from the container, A surface layer comprising a material having no heat adhesive and positioned at an upper end of the sealing body of the container, a heat adhesive resin layer laminated with a thin thermoplastic resin having an appropriate thickness on the surface layer, a thermoplastic resin adhered to a lower end of the heat adhesive resin layer, or An adhesive layer made of an adhesive, an intermediate substrate layer adhered to the adhesive layer and formed of an aluminum foil, a plastic film, etc., and a sealing adhesive layer adhered to a lower end of the intermediate substrate layer to include a heat-adhesive plastic resin or an adhesive, and bonded to a container; Container encapsulation body with an open top is configured, and the Republic of Korea Patent Publication No. 2010-004028 No. 6 discloses a sealing material for containers of food products.
