Description

농수산물 포장 상자용의 통풍성 골판지{Corrugated cardboard with ventilating opening for wrapping box}Corrugated cardboard with ventilating opening for wrapping box

본 발명은 농수산물을 포장하는 포장 상자의 제작에 사용하는 통풍성 골판지에 관한 것이다.The present invention relates to a breathable corrugated cardboard for use in the production of packaging boxes for packaging agricultural and marine products.

귤이나 사과 및 배 등의 과일과 배추나 상추 등의 채소 및 꽃게등의 수산물등은 골판지로 제작된 포장 상자에 담아 유통시키고 있다.Fruits such as tangerines, apples and pears, vegetables such as cabbage and lettuce, and aquatic products such as crabs are distributed in cardboard boxes.

그런데 과일이나 야채등을 골판지 포장 상자 속에 넣어 보관하게 되면, 특히 바닥이나 벽면에 닿아 있는 것들은 통풍성이 나빠 쉽게 썩게 되는 문제가 있다.However, when the fruits or vegetables are stored in a cardboard packaging box, especially those that touch the floor or the wall has a problem of bad ventilation easily decayed.

이 때문에 도 3에 도시하는 것과 같이 통풍성을 좋게 하기 위하여 포장 상자(20)의 벽면에 직경 2∼3㎝정도 크기의 통풍구멍(21)을 복수개 형성하여, 이들 통풍구멍(21)을 통해 외부로부터 공기가 드나들게 되므로 과일이나 채소등의 부패를 방지하고 있다.For this reason, as shown in FIG. 3, in order to improve ventilation, a plurality of ventilation holes 21 having a diameter of about 2-3 cm are formed on the wall surface of the packing box 20, and from the outside through these ventilation holes 21 As air enters, it prevents corruption such as fruits and vegetables.

그러나 포장상자(20)에 통풍구멍(21)을 뚫어 형성하는 종래 방식에 의하면 다음과 같은 여러가지 문제점을 유발하고 있다.However, the conventional method of forming the ventilation hole 21 in the packing box 20 causes various problems as follows.

통풍구멍(21)의 직경이 크고 또 골판지의 내외주를 관통하도록 직접 천공되므로 공기의 유통은 원활하나 내부 습도 유지에 곤란성이 있어 수분 함량이 높은 상추 등의 야채의 경우 쉽게 건조되어 상품성이 저하되며, 또한 통풍구멍(21)을 통해 벌레나 먼지 및 이물질이 내부로 유입될 우려가 있으며, 포장상자의 표면에 인쇄된 상품명과 상호 및 주소등의 인쇄부(22)를 손상시켜 광고성 및 상품성을 떨어 뜨리고 포장 상자의 미관을 저하시키게 된다.Since the diameter of the ventilation hole 21 is large and directly perforated to penetrate the inner and outer circumferences of the corrugated paper, the air is smoothly distributed, but it is difficult to maintain the internal humidity. Vegetables such as lettuce, which have a high moisture content, are easily dried to deteriorate their commerciality. In addition, there is a risk that bee dust and foreign substances are introduced into the interior through the ventilation hole 21, and damage to the printing unit 22, such as the product name, trade name and address printed on the surface of the packaging box to reduce the advertising and commercial properties. It lowers and deteriorates the aesthetics of the box.

이와같이 통풍구멍(21)은 골판지를 재단하여 전개도 박스로 만들고 인쇄작업을 한 후 조립하여 내용적을 가지는 상자로 만들며, 박스 완성 후 적당한 위치에 통풍구멍(21)을 뚫게 되는데 이때 인쇄부위(22)에 의해 통풍구멍(21)의 위치가 제한을 받으며, 또 잘못하면 도시한 것과 같이 인쇄부위(22)가 잘려나가게 되어 문자 식별이 곤란해지고 미관을 저하시키게 만드는 것이다.In this way, the ventilation hole 21 is cut out of corrugated cardboard into a developed view box, printed and assembled, and then made into a box having an internal volume. After the completion of the box, the ventilation hole 21 is drilled at a suitable position. As a result, the position of the ventilation hole 21 is limited, and if it is mistaken, the printing portion 22 is cut off as shown in the figure, making character identification difficult and deteriorating aesthetics.

또 상자의 구석진 곳에는 통풍구멍(22)을 뚫기가 곤란하므로 구석 부위에 위치하는 과일이나 야채의 경우 통풍성이 나빠 쉽게 상하는 문제점이 있으며, 살아 있는 꽃게등의 경우 톱밥과 함께 포장상자에 담게 되므로 꽃게의 선도 유지를 위하여 통풍구멍을 형성할 경우 톱밥이 외부로 누출되므로 통풍구멍을 형성할 수 없어 신선도 유지 기간이 짧다는 문제점도 있다.In addition, it is difficult to drill the ventilation hole 22 in the corner of the box, so the fruit or vegetable located in the corner has a bad ventilation, which is easily damaged, and in the case of live crabs, such as live crabs, they are put in a box together with sawdust. When the ventilation hole is formed to maintain the freshness of the sawdust, the sawdust leaks to the outside, so the ventilation hole cannot be formed.

이에 본 발명은 상기한 문제점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은 통풍성이 상자의 구석 구석 까지 미치며, 습도 조절 가능이 유지되고 이물질의 유입을 방지하며, 인쇄부분의 손상 및 미관의 저하를 방지하는 농수산물을 포장 상자용 통풍성 골판지를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above-mentioned problems, and its object is to allow ventilation to reach every corner of the box, maintain humidity control, prevent inflow of foreign matters, and prevent damage to print parts and deterioration of aesthetics. It is to provide a ventilated cardboard for packing the agricultural and marine products.

상기한 목적을 달성하기 위하여 본 발명은 S자 형으로 연속하여 굴곡진 중심지와 그 중심지의 양측에 접착되는 표면지와 이면지를 포함하는 적어도 3층 구조로 구성되는 포장 상자용 골판지에 있어서,In order to achieve the above object, the present invention is a corrugated cardboard for a packaging box consisting of at least three-layer structure comprising a center paper continuously curved in the S-shape and the surface paper and the backing paper bonded to both sides of the center paper,

상기 각각의 중심지와 표면지 및 이면지에는 각기 독립적으로 천공되는 0.5∼2㎜ 크기의 복수개의 소공이 형성되어 있는 것을 특징으로 한다.Each of the center paper, the surface paper and the backing paper is characterized in that a plurality of small pores having a size of 0.5 to 2 mm each independently drilled.

도 1은 본 발명에 의한 포장 상자용 통풍성 골판지의 단면도이며, 도 2는 본 발명에 의한 포장 상자용 통풍성 골판지의 제조 과정을 설명하는 도면이다.1 is a cross-sectional view of a ventilated cardboard for a packaging box according to the present invention, Figure 2 is a view illustrating a manufacturing process of a ventilated cardboard for a packaging box according to the present invention.

도 1에 있어서, 통풍성 골판지(1)는 표면지(2)와 중심지(3) 및 이면지(4)로 구성되며, 중심지(3)는 S자형으로 굴곡진 형상으로 중심지(3)의 양측 산부분(3a)(3b)(정점부)들을 따라 접착제에 의해 표면지(2)와 이면지(4)가 접착되는 3층 구조로 되어 있다.In FIG. 1, the ventilated cardboard 1 is composed of a surface paper 2, a center paper 3, and a backing paper 4, and the center paper 3 is curved in an S-shape, and both mountain portions of the center paper 3 are curved. A three-layer structure is formed in which the surface paper 2 and the backing paper 4 are bonded together by an adhesive along the (3a) and (b) vertices.

또 이면부(4) 또는 표면지(2)에는 계속해서 S형의 굴곡진 중심지와 평판지를 덧붙여 5층 또는 7층 구조로 골판지를 더욱 두껍게 구성할 수도 있다.In addition, the back surface 4 or the surface paper 2 may be further formed with a curved center of S-shape and flat paper, and the corrugated paper may be further thickened in a five- or seven-layer structure.

각각의 표면지(2), 중심지(3) 및 이면지(4)에는 통풍을 위한 구멍으로서 각각 독립적으로 천공된 복수개의 소공(5)(6)(7)들이 형성되어 있으며, 이들 각각의 판지(2)(3)(4)들에 천공된 소공(5)(6)(7)은 서로 일직선 축선상에 정렬된 것이 아니라 불규칙 하게 되어 있으며, 중심지(3)에 천공된 소공(6)들은 각기 다른 방향을 향하고 있어, 작은 소공(5)(6)(7)들이 서로 어긋나 미로를 형성하고 있다.Each of the surface paper 2, the center paper 3, and the back paper 4 are formed with a plurality of small holes 5, 6, 7 which are each independently perforated as holes for ventilation, and each of these paperboards ( The pores 5, 6, 7 perforated in 2) (3) (4) are not aligned on a straight line with each other but are irregular, and the pores 6 perforated in the center 3 are each Facing in the other direction, the small pores 5, 6 and 7 are shifted from each other to form a maze.

이 소공(5)(6)(7)들은 0.5∼2㎜ 크기, 바람직하기로는 0.5∼1㎜ 크기의 원형이나 타원형(타원형의 경우 장지름 기준) 및 사각구멍 등의 형상으로 천공되며, 골판지(1)로 제작되기 전 단계에서의 평판지 단계에서 상기 소공(5)(6)(7)들이 천공되어지게 된다.The small holes 5, 6 and 7 are perforated in the shape of a circle or oval having a size of 0.5 to 2 mm, preferably 0.5 to 1 mm (long diameter in the case of an ellipse), and a square hole. The small holes (5), (6) and (7) are to be drilled in the flat paper step in the step before the production of 1).

이하에 통풍성 골판지(1)를 제조하는 과정을 도 2를 참조하여 설명한다.Hereinafter, a process of manufacturing the ventilated cardboard 1 will be described with reference to FIG. 2.

보빈(8)(9)(10)에 감겨진 각각의 평판지(2)(11)(4)들에는 제지 회사에서의 생산공정중이나 또는 골판지로의 제작 공정에 앞서 상하 한쌍의 금형으로 되는 펀칭기(12)(13)들에 의해 0.5∼2㎜ 크기로 일정 간격마다 또는 평판지(2)(11)(4) 마다 다른 간격으로 소공(5)(6)(7)을 뚫는다.Punching machines, each of which are wound on bobbins 8, 9 and 10, have a pair of upper and lower molds in the production process at the paper company or prior to the corrugation process. The small holes (5) (6) (7) are drilled by (12) (13) at intervals of 0.5 to 2 mm at regular intervals or at different intervals for the flat sheets (2) (11) and (4).

중간의 평판지(11)는 기어 형상의 한쌍의 맞물린 요철 형성 기어부(14)를 통과하면서 S자형이 연속하여 굴곡진 파형몸체를 가지는 중심지(3)로 성형된다.The intermediate flat paper 11 is formed into a central paper 3 having a corrugated body with S-shape continuously while passing through a pair of gear-shaped interdigital unevenness forming gear portions 14.

S자형상으로 굴곡진 중심지(3)는 접착 도포 로울러부(15)를 통과하면서 양측의 정점부(3a)(3b)들에 접착제가 도포되어지게 되며, 한쌍의 접착 로울러(16) 사이를 통과하면서 양측의 평판지(2)(4), 즉 표면지(2)와 이면지(4)가 중심지(3)의 양측에 접착되어지게 되므로써 통풍성 골판지(1)가 형성된다.The center 3 curved in an S-shape passes an adhesive coating roller portion 15 while adhesive is applied to both apex portions 3a and 3b, and passes between a pair of adhesive rollers 16. On the other hand, the flat sheet papers 2 and 4 on both sides, that is, the front sheet paper 2 and the back sheet paper 4 are bonded to both sides of the center sheet 3, thereby forming the corrugated cardboard sheet 1.

이와같이 하여 제조된 통풍성 골판지(1)를 사용하여 포장 상자를 만들게 되면, 상자의 외표면을 형성하는 표면지(2)에 인쇄를 하더라도 소공(5)들의 크기가 작으므로 인쇄 내용이 잘려나가는 일이 없고 따라서 상자의 미관을 해치는 일도 없다.When the packaging box is made using the ventilated cardboard (1) manufactured in this way, even if printing on the surface paper (2) forming the outer surface of the box, because the small pores (5) the size of the print content is cut off And therefore does not harm the beauty of the box.

이와같은 본 발명은 표면지(2)의 소공(5)을 통과한 공기는 중심지(3)에 형성되는 제1공간(17)으로 유입되고, 다시 소공(6)을 통과하여 제2공간(18)으로 유입된 후 이면지(4)에 형성된 소공(7)을 통하여 상자 내부로 공기가 유입되며, 상자 내부의 공기가 외부로 배출되는 경로는 앞서와 반대 경로로 이루어진다.According to the present invention, the air passing through the small holes 5 of the surface paper 2 flows into the first space 17 formed in the center 3, and then passes through the small holes 6 to the second space 18. After being introduced into the air through the small holes 7 formed in the backing paper 4, the air is introduced into the box, the path of the air inside the box is discharged to the outside is made of the opposite path.

이 소공(5)(6)(7)들은 직경이 매우 작으나 전체 표면적에 걸쳐 많은 갯수가 천공되므로 전체 공기 통과 단면적은 종래의 통풍 구멍들에 비해 작지 아니하여 통풍성이 저하되지 아니하며, 특히 상자의 구석진 각 부분마다도 구멍의 형성이 가능하므로 통풍효과가 전체적으로 고르게 미치게 된다.These pores (5) (6) (7) are very small in diameter but many are drilled over the entire surface area, so that the total air passage cross section is not small compared to conventional vent holes so that the ventilation is not deteriorated, especially in the corners of the box. Holes can be formed in each part, so the ventilation effect is evenly distributed.

또 공기가 아무런 거침없이 일직선으로 관통하는 것이 아니라 미로를 통하여 연통하기 때문에 그 과정에서 판지(2)(3)(4)들과 접촉하는 체류 시간이 길어져 판지(2)(3)(4)들에 의해 습도 조절 기능이 발휘되어져 야채의 저장시 통풍성의 유지 및 쉽게 마르게 되는 현상을 방지할 수 있게 되는 것이다.In addition, since the air communicates through the maze rather than straight through without any roughness, the residence time of contacting the cardboard (2) (3) (4) in the process is long, so the cardboard (2) (3) (4) By the humidity control function is exhibited to be able to prevent the phenomenon of maintaining the ventilation and easily dry during storage of vegetables.

또한 본 발명의 골판지는 농수산물 뿐 아니라 공기 유통에 의한 내용물의 손상을 방지하는 것인한 의류등의 보관 상자에도 적용되는 것임은 물론이다.In addition, the corrugated cardboard of the present invention is applied not only to agricultural and marine products, but also to storage boxes such as clothing as long as it prevents damage to contents by air circulation.

이상과 같은 본 발명에 의하면 농수산물 포장 상자를 제작 하는 데 사용하는 골판지를 제조함에 있어 미리 표면지와 중심지 및 이면지 각각에 등 간격 또는 서로 다른 간격을 가지도록 작은 크기의 소공들을 독립적으로 천공한 후 적층 접합하여 다층 구조물인 골판지를 만들게 되므로써, 이 골판지를 사용하여 포장 상자를 만들 경우 통풍성이 유지되면서 또한 공기 유통 경로의 복잡성으로 공기와 종이 판지의 접촉 시간이 늘어나 종이재질의 고유한 특성중 하나인 습도 조절 기능을 발휘하게 되며, 구멍의 크기가 매우 작고 서로 어긋나서 형성되므로 벌레나 먼지 및 이물질의 유입을 차단하게 되며, 표면지에의 인쇄시 인쇄 내용의 손상을 최소화하여 상자의 미관을 해치지 아니하는 효과가 있으며, 꽃게 등의 수산물 포장에 사용시에 톱밥등이 외부 누출 되지 않으면서 공기의 유통이 원활하여 선도가 오래 유지되는 효과가 있다.According to the present invention as described above in the manufacture of corrugated cardboard used to produce a packaging box for agricultural and marine products, the small pores of the small size so as to have the same or different intervals on the surface paper and the center paper and the back paper beforehand and then laminated By joining together to make a multi-layered corrugated cardboard, the packaging box is made of corrugated cardboard to maintain ventilation and increase the contact time between air and paper cardboard due to the complexity of the air flow path. It has an adjustable function, and the hole size is very small and formed by shifting each other to block the ingress of dust and foreign substances, and to minimize the damage of the printed contents when printing on the surface paper so as not to harm the aesthetics of the box. Sawdust, etc., are used for packaging seafood such as blue crabs. If you do not export document circulation of air it has the effect that smoothly by maintaining the lead long.
