Description

개구부를 개폐토록 하는 개폐날개의 사용편의성을 개선한 보온보냉 팩{warm and cold keeping pack improved the usability of opening and closing wings}Warmth and cold keeping pack improved the usability of opening and closing wings}

본 발명은 보온보냉이 가능한 팩에 관한 것으로, 특히 보온보냉팩에 수납되어지는 물품이 출입되는 개구부를 개폐하기 위한 개구부의 상측으로 더 연장된 개폐날개의 상변에 접착수단이 구비된 상태에서 사용의 편의성을 제공토록 한 것이다.The present invention relates to a pack capable of keeping warm, and in particular, it is used in a state in which an adhesive means is provided on the upper side of an opening and closing wing that extends further to the upper side of the opening for opening and closing an opening in which an article stored in the heat insulating pack is opened and closed. This is to provide convenience.

현재 보온보냉이 가능한 팩은 발포되어진 발포시트의 내측과 외측으로 각각 내피와 외피를 구비하고, 상기 내피는 통상 인체에 무해한 PE계열의 필름을 합지하거나 또는 PE계열의 용융액을 티다이공법에 의하여 코팅하고, 외피는 외부의 열을 차단하기 위한 은박층과 상기 은박층의 외면에는 은박층의 보호 또는 인쇄를 위한 PET필름이 주로 합지한다.Currently, packs that can be kept warm are provided with inner and outer skins, respectively, on the inner and outer sides of the foamed foam sheet, and the inner skin is coated with a PE-based film, which is usually harmless to the human body, or coated with a PE-based melt by a T-die method. And, the outer layer of the silver foil layer for blocking the heat from the outside and the outer surface of the silver foil layer is a PET film for protecting or printing the silver foil layer.

또한 이 상태에서 물품의 수납을 위한 공간확보를 위하여 일정면적을 갖는 팩을 제조할 수 있는 넓이를 갖는 시트를 접어서 하변을 제외하고 좌우변에 열을 가하여 컷팅과 동시에 접착라인을 형성하게 된다.Also, in this state, in order to secure space for storage of the article, a sheet having an area capable of manufacturing a pack having a certain area is folded, and heat is applied to the left and right sides except for the lower side to form an adhesive line at the same time as cutting.

이때 내피를 형성하는 PE계열이 동일한 재질로 이루어져 쉽게 접착이 이루어지게 되는 것이다. At this time, the PE line forming the endothelial is made of the same material, so that it is easily adhered.

그러나 이때 도 1에 도시된 바와 같이 좌우변의 접착라인 컷팅과 동시에 접착이 이루어지므로 접착폭이 작아 수납을 위한 공간에 수납된 물품의 하중에 의하여 쉽게 터짐이 발생될 수 있고, 또한 접착불량에 의한 제품하자의 원인이 되고 있는 것이다.However, at this time, as shown in FIG. 1, since the adhesive lines are cut at the same time as the adhesive lines are cut at the right and left sides, the width of the article stored in the space for storage can be easily burst due to the small adhesive width, and the product due to poor adhesion is also possible. It is causing the defect.

따라서 최근에는 도 2 및 도 3에 도시된 바와 같이 접착라인을 일정한 폭을 갖도록 접착띠로 이루어지게 함으로서 터지는 문제점을 해소하였던 것이다.Therefore, recently, as shown in FIGS. 2 and 3, the problem of bursting was solved by making the adhesive line to be made of an adhesive band to have a constant width.

그러나 이렇게 접착라인이 일정한 폭을 갖도록 할 경우에는 개폐날개에서 문제가 발생할 수 있다.However, if the adhesive line is to have a certain width, problems may occur in the opening and closing wings.

즉, 팩의 개폐구조는 팩의 확보된 공간을 개폐토록 하기 위하여 팩의 전후면을 구비하는 어느 한면(통상 후면)의 길이를 길게 연장하여 개폐날개를 구비하고 상기 개폐날개의 상변에는 양면테이프로 이루어진 접착수단을 구비하게 되어 접착수단의 이형지를 제거하면서 팩의 개구부를 개폐토록 하고 있다.That is, the opening and closing structure of the pack extends the length of any one side (normally the rear side) provided with the front and rear surfaces of the pack to open and close the secured space of the pack, and includes an opening and closing wing, and a double-sided tape on the upper side of the opening and closing wing. The adhesive means is provided to open and close the opening of the pack while removing the release paper of the adhesive means.

그런데 종래 제조방식과 같이 컷팅과 동시에 접착라인으로 형성할 경우에는 이러한 개폐날개에 변형이 발생되지 않지만, 개선된 방법과 같이 좌우변이 일정폭을 갖는 접착띠로 이루어질 경우에 이러한 개폐날개에도 접착띠의 폭만큼 열이 전달되면서 외피와 내피의 온도변형의 차이로 인하여 비틀림 등이 발생되는 문제가 있고, 이렇게 변형된 개폐날개를 이용하여 개구부를 밀폐토록 할 경우에 사용상 상당한 불편함을 초래하게 되는 것이다.However, in the case of forming with an adhesive line at the same time as cutting in the conventional manufacturing method, deformation does not occur in these opening and closing wings, but when the left and right sides are formed of an adhesive band having a certain width, as in the improved method, the width of the adhesive band also applies to these opening and closing wings. As much heat is transferred, there is a problem in that torsion and the like occur due to a difference in temperature deformation between the outer skin and the inner skin, and when opening and closing the opening using the deformed opening and closing wing, there is considerable inconvenience in use.

따라서 본 발명에서는 이러한 문제점을 해소하고자 하는 것으로, 보온보냉 팩의 좌우변에 접착되는 부분을 형성함에 있어서 일정한 폭의 접착띠로 구현하여 보온보냉 팩이 쉽게 터지지 않고 내구성을 확보함과 동시에 개폐날개의 비틀림을 방지하도록 한 것이다.Therefore, in the present invention, to solve this problem, in forming a portion to be adhered to the left and right sides of the heat preservation pack, it is implemented with an adhesive band of a constant width, and the heat preservation pack is not easily popped and the durability is secured, and at the same time twisting of the opening and closing wings is twisted. It is to prevent.

이를 위하여 물품의 수납을 위한 수납공간의 공간확보를 위하여 일정면적을 갖는 보온보냉 팩을 제조할 수 있는 넓이를 갖는 시트를 접어서 하변을 제외하고 좌우변에 열을 가하여 접착띠를 형성할 경우에 개폐날개가 형성되는 위치에 접착띠를 형성하는 히팅바만을 제거토록 하여 개폐날개의 좌우변에는 컷팅만 이루어지도록 함으로서 간단하게 해결토록 한 것이다.To this end, in order to secure a space in a storage space for storage of goods, a sheet having an area capable of manufacturing a thermal insulation pack having a certain area is folded and opened and closed when heat is applied to the left and right sides except for the lower side to form an adhesive strip. It was solved simply by removing only the heating bar forming the adhesive band at the position where the wings are formed, so that only the left and right sides of the opening and closing wings are cut.

따라서 보온보냉팩의 좌우변에 형성되는 접착부분이 일정한 폭의 접착띠로 구현됨에도 불구하고 연장된 개폐날개의 좌우변에는 열이 전달되지 않으면서 컷팅이 이루어져 개폐날개의 형태변형이 방지되고, 개폐날개의 접착수단, 즉 양면테이프로 이루어진 접착수단의 이형지를 쉽게 제거할 수 있어 사용이 편리함은 물론, 개구부의 밀폐도 용이하고 이형지의 제거가 말끔히 이루어지므로 접착수단을 이용한 개구부의 밀폐가 긴밀하게 이루어지게 되는 것이다.Therefore, despite the fact that the adhesive portions formed on the left and right sides of the thermal insulation pack are implemented with adhesive bands of a constant width, cutting is performed without heat being transmitted to the left and right sides of the extended opening and closing blades to prevent shape deformation of the opening and closing wings, The adhesive means, that is, the release paper of the adhesive means made of double-sided tape can be easily removed, which is convenient for use as well as the sealing of the opening is easy and the removal of the release paper is made neatly, so that the opening of the opening using the adhesive means is made tight. Will be.

또한, 사용자가 개폐날개를 이용하여 팩을 밀봉하고자 하는 경우에 접힘라인에 의하여 개폐날개의 접힘이 자연스럽게 유도되므로 사용이 매우 편리하다.In addition, when the user wants to seal the pack using the opening and closing wings, the folding of the opening and closing wings is naturally induced by the folding line, which is very convenient.

이하 첨부도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 4에 도시된 바와 같이 본 발명의 팩 구조는 다수의 기포가 형성되게 발포되어진 완충력을 구비한 발포시트(10)의 내측과 외측으로 각각 내피(20)와 외피(30)를 구비하고, 상기 내피(20)는 인체에 무해한 PE계열의 필름을 발포시트(10)와 합지하거나 또는 PE계열의 용융액을 티다이공법에 의하여 코팅이 이루어지고, 외피(30)는 외부의 열을 차단하기 위한 은박층과 상기 은박층의 외면에는 은박층의 보호 또는 인쇄를 위한 PET필름이 합지되어 팩을 제조하기 위한 시트가 구성될 수 있다.As shown in Figure 4, the pack structure of the present invention is provided with an inner shell 20 and an outer shell 30, respectively, inside and outside of a foam sheet 10 having a buffering force foamed to form a number of bubbles, respectively. The inner skin 20 is coated with a PE-based film harmless to the human body with the foam sheet 10, or a PE-based melt is coated by a T-die method, and the outer skin 30 is silver foil for blocking external heat. On the outer surface of the layer and the silver foil layer, a PET film for protecting or printing the silver foil layer may be laminated to form a sheet for manufacturing a pack.

또한 이 상태에서 물품의 수납을 위한 내공간 확보를 위하여 일정면적을 갖는 팩(100)을 제조할 수 있는 넓이를 갖는 상기와 같이 합지되어진 시트(110)를 접어서 하변(111)을 제외하고 좌우변(112,113)에 열을 가하여 컷팅과 동시에 접착띠(120)를 형성하거나 또는 열접착 공정을 먼저 수행하여 접착띠(120)를 형성한 후 컷팅공정을 수행할 수 있게 된다.In addition, in this state, in order to secure the inner space for storage of the article, the sheet 110 laminated as described above having a width capable of manufacturing a pack 100 having a certain area is folded, and the left and right sides except for the lower side 111. By applying heat to (112,113), the adhesive band 120 is formed simultaneously with the cutting, or the thermal bonding process is first performed to form the adhesive band 120, and then the cutting process can be performed.

즉, 시트(110)를 접어 좌우변만을 열접착으로 접착하여 포장용 백(bag)의 형태로 이루어지도록 하여 수납공간을 마련하고, 그 수납공간의 상측에는 팩(100)의 전후면을 구비하는 면 중 어느 한면의 길이를 길게 연장하여 개폐날개(130)를 형성함으로써 팩(100)에 식품 등의 물품을 수납한 상태에서 개폐날개를 이용하여 밀봉할 수 있게 구비될 수 있다.That is, by folding the sheet 110, only the left and right sides are adhered by heat bonding, so that the storage space is provided to be made in the form of a bag for packaging, and the front and rear surfaces of the pack 100 are provided on the upper side of the storage space. By forming the opening and closing wings 130 by extending the length of any one of the sides, it may be provided to be sealed by using the opening and closing wings in a state in which an article such as food is stored in the pack 100.

이때, 상기 시트(110)를 접어서 팩(100)으로 제조하는 방법은, 도 5에 도시된 바와 같이 시트(110)의 하변(111)을 단순 접는 방식으로 접어서 수납공간을 마련하거나, 또는 도 6에 도시된 바와 같이 시트(110)의 하변(111)을 2단으로 접어서 단면이 W형상으로 이루어지도록 하여 물품을 수납공간에 수납할 때 바닥면이 수평으로 펼쳐지면서 수납공간에 담을 수 있는 용량을 늘릴 수 있도록 구비될 수 있으며, 이렇게 접혀진 시트(110)의 하변(111)을 제외하고, 좌우변(112,113)에 열을 가하여 컷팅과 동시에 접착띠(120)를 형성하거나 열 접착후 컷팅을 수행할 수 있게 된다.At this time, the method of manufacturing the pack 110 by folding the sheet 110, as shown in FIG. 5, provides a storage space by folding the lower side 111 of the sheet 110 in a simple folding method, or FIG. As shown in the figure, the lower side 111 of the sheet 110 is folded in two stages so that a cross section is formed in a W shape, so that when the article is stored in the storage space, the bottom surface expands horizontally and the capacity to be stored in the storage space. It may be provided to be extended, except for the lower side 111 of the folded sheet 110, by applying heat to the left and right sides 112, 113 to form an adhesive strip 120 at the same time as cutting or to perform cutting after heat bonding. It becomes possible.

이때 내피(20)를 형성하는 PE계열이 발포시트(10)와 동일한 재질로 이루어짐으로 쉽게 접착이 이루어지게 되는 것이고, 접착된 상태에서 발포시트(10)와 내피(20)가 합지된 상태이어서 박리현상도 발생되지 않게 되는 것이다. At this time, since the PE line forming the endothelial 20 is made of the same material as the foamed sheet 10, it is easily adhered, and in the bonded state, the foamed sheet 10 and the endothelial 20 are in a laminated state to peel. There is no phenomenon.

이때 물품의 수납을 위한 공간확보를 위하여 일정면적을 갖는 보온보냉 팩(100)을 제조할 수 있는 넓이를 갖는 시트(110)를 접어서 하변을 제외하고 좌우변에 열을 가하여 컷팅과 동시에 접착띠(120)를 형성할 경우에 개폐날개(130)가 형성되는 위치에 접착띠를 형성하는 컷팅수단(2)이 구비된 히팅바(1)에서 개폐날개의 좌우변에 위치되어지는 히팅바만을 제거토록 하여 개폐날개의 좌우변에는 열이 전달 되지 않고 컷팅만 이루어지도록 한 것이다.At this time, in order to secure space for storage of the article, the sheet 110 having an area capable of manufacturing a heat preservation cold pack 100 having a certain area is folded, and heat is applied to the left and right sides except for the lower side, and at the same time cutting and adhesive bands ( In the case of forming 120), only the heating bar located on the left and right sides of the opening and closing wings is removed from the heating bar 1 provided with the cutting means 2 for forming the adhesive band at the position where the opening and closing wings 130 are formed. Therefore, heat is not transmitted to the left and right sides of the opening and closing wings, so that only cutting is performed.

또는 열접착에 의하여 접착띠(120)를 형성한 후, 이후 공정에서 컷팅을 할 경우에도 도 8과 같이 개폐날개(130)가 형성되는 위치에 접착띠를 형성하는 히팅바(1)에서 개폐날개의 좌우변에 위치되어지는 히팅바만을 제거토록 하여 개폐날개의 좌우변에는 열이 전달 되지 않으므로 접착되지 않고 수납공간의 좌우변에만 접착되도록 한 것이다.Alternatively, after forming the adhesive strip 120 by thermal bonding, even when cutting in a subsequent process, the opening and closing wings in the heating bar 1 forming the adhesive strip at the position where the opening and closing wings 130 are formed as shown in FIG. 8. Since only the heating bar located on the left and right sides of the panel is removed, heat is not transmitted to the left and right sides of the opening and closing wings, so that it is adhered only to the left and right sides of the storage space.

따라서 도 9와 같이 보온보냉 팩의 연장된 개폐날개가 자동생산이 가능하면서 개폐날개의 좌우변만을 제외하고, 즉 수납공간의 좌부변에만 접착띠가 형성되는 것이다.Therefore, as shown in FIG. 9, the extended opening and closing wings of the heat-insulating pack are capable of automatic production, and excluding the left and right sides of the opening and closing wings, that is, an adhesive band is formed only on the left side of the storage space.

이때, 상기 히팅바(1)는 도 10에 도시된 바와 같이 수납공간의 좌우변에 접착띠(120)에 대응하는 부분보다 상대적으로 길게 연장부(1a)를 형성하여 도 11과 같이 수납공간의 좌우변 접착띠(120)을 포함하여 수납공간의 접착띠 상단, 즉 개폐날개(130)의 하단 중 일부인 개폐날개가 접힘되는 부분에도 열을 가하여 눌림면(135)을 형성하면 개폐날개를 이용하여 수납공간을 밀봉할 때 개폐날개의 접힘이 유도되도록 할 수 있다.At this time, the heating bar (1), as shown in Figure 10 to form an extension portion (1a) relatively longer than the portion corresponding to the adhesive strip 120 on the left and right sides of the storage space as shown in Figure 11 of the storage space When the pressing surface 135 is formed by applying heat to the upper part of the adhesive band of the storage space including the right and left side adhesive bands 120, that is, a part of the lower end of the opening and closing wings 130, which is folded, the opening and closing wings are used. When sealing the storage space, folding of the opening and closing wings can be induced.

즉, 본 발명의 팩을 구성하는 시트(110)는 상술한 바와 같이 발포시트(10), 내피(20), 외피(30)를 포함하여 구성될 수 있는데, 상기와 같이 개폐날개(130)의 하단 중 일부분에도 히팅바(1)의 연장부(1a)를 이용하여 열을 가하면 해당부위가 용융되면서 매우 얇은 두께의 눌림면(135)이 형성될 수 있다.That is, the sheet 110 constituting the pack of the present invention may be configured to include a foam sheet 10, an inner shell 20, an outer shell 30 as described above, as described above, of the opening and closing wings 130 When heat is applied to an extended portion 1a of the heating bar 1 to a part of the lower portion, a correspondingly thin pressing surface 135 may be formed while the corresponding portion is melted.

또한, 발포시트(10) 또는 내피(20) 또는 외피(30)가 단열을 위하여 특정한 두께를 가지거나 또는 외면이 특정한 무늬를 가지는 경우에도 해당 부위, 즉 눌림면(135)에는 두께 및 무늬가 없이 열로 가열되어 매우 얇은 두께로 변형되기 때문에 개폐날개의 접힘 유도를 더욱 효율적으로 수행할 수 있게 된다.In addition, even when the foam sheet 10 or the inner skin 20 or the outer skin 30 has a specific thickness for insulation or a specific pattern on the outer surface, that portion, that is, the pressed surface 135 has no thickness and pattern. Since it is heated and deformed to a very thin thickness, it is possible to more efficiently perform induction of folding of the opening and closing wings.

따라서 사용자가 개폐날개(130)를 이용하여 팩(100)을 밀봉하고자 하는 경우에 개폐날개(130)가 접힘되는 부분을 임의로 설정할 필요없고 해당 부분을 억지로 접을 필요없이 도 12에 도시된 바와 같이 개폐날개의 접힘라인에 의하여 개폐날개의 접힘이 자연스럽게 유도되므로 개폐날개의 이형지를 제거한 후 간편하게 팩을 밀봉할 수 있게 되는 것이다.Therefore, when the user wants to seal the pack 100 by using the opening and closing wings 130, there is no need to arbitrarily set the part where the opening and closing wings 130 are folded, and the opening and closing as shown in FIG. Since the folding of the opening and closing wings is naturally induced by the folding line of the wings, it is possible to easily seal the pack after removing the release paper of the opening and closing wings.

이때, 상기 눌림면(135)의 폭은 팩(100)의 사이즈 또는 수납공간의 크기에 따라서 달리 구성할 수 있는 것으로, 수납공간을 크게 형성하는 경우 개폐날개(130)가 접힘되는 부분이 각지지 않고 만곡되게 절첩되어 접힘이 이루어지도록 상대적으로 눌림면(135)의 폭을 더 넓게 형성하거나, 또는 눌림면이 여러 칸으로 분할되게 형성하여 개폐날개(130)의 접힘을 더욱 유도하도록 할 수 있다.At this time, the width of the pressing surface 135 may be configured differently depending on the size of the pack 100 or the size of the storage space, and when the storage space is formed large, the part where the opening and closing wings 130 are folded is supported. Instead, it is folded to be curved to form a relatively wider width of the pressing surface 135 so that folding is achieved, or the pressing surface is formed to be divided into several cells to further induce folding of the opening and closing wings 130.

또한, 본 발명의 팩을 구성하는 시트(110)가 발포시트(10), 내피(20), 외피(30)에 더하여 외부의 열을 차단하기 위한 은박층이 더 포함되어 구성될 수 있는데, 이때 히팅바(1)의 연장부(1a)를 이용하여 수납공간의 접착띠 상단, 즉 개폐날개(130)의 하단 중 일부에 열을 가하면 은박층을 제외한 다른 층이 용융되어진 눌림면(135)을 형성할 수 있다.In addition, the sheet 110 constituting the pack of the present invention may be configured by further including a foam layer 10, an inner skin 20, an outer skin 30, and a silver foil layer for blocking external heat. When heat is applied to a part of the upper end of the adhesive band of the storage space, that is, the lower end of the opening / closing wing 130 using the extending portion 1a of the heating bar 1, the pressing surface 135 in which other layers except the silver foil layer is melted is melted. Can form.

즉, 시트를 구성하는 여러 층들 중 히팅바에 의하여 가열되는 온도에 의하여 은박층을 제외한 나머지 층들이 용융되면서 눌림면(135)의 두께가 얇아지게 되는데, 이로 인하여 개폐날개(130)의 접힘부위를 따로 설정할 필요없이 자연스럽게 접힘 유도가 이루어지게 된다.That is, the thickness of the pressing surface 135 becomes thin as the remaining layers except the silver foil layer are melted due to the temperature heated by the heating bar among the various layers constituting the sheet, which separates the folding portion of the opening and closing wings 130. The folding is induced naturally without the need for setting.
