본 발명의 골판지(100)는 플라스틱 재질로 이루어지는 바, 폴리프로필렌, 폴리에틸렌, 피이브이시 등 다양한 플라스틱 재질 중에서 선택된 어느 하나로 이루어질 수 있으며, 특별한 재질로 제한되지는 않는다. Corrugated cardboard 100 of the present invention is made of a plastic material bar, polypropylene, polyethylene, fibish may be made of any one selected from a variety of plastic materials, and is not limited to a special material.
상기 도면들에 일 예시된 것처럼, 본 발명의 골판지(100)는 상판부(10)와, 하판부(20)와, 리브(30)와, 골부(40)와, 골분할부(50)를 포함하여 구성된다.As illustrated in the drawings, the corrugated cardboard 100 of the present invention includes an upper plate portion 10, a lower plate portion 20, a rib 30, a rib portion 40, and a bone dividing portion 50. It is composed.
상기 상판부(10)와 하판부(20)는 평평한 판재로서 상호 동일하게 장방형으로 형성될 수 있다.The upper plate portion 10 and the lower plate portion 20 may be formed in the same rectangular shape as a flat plate material.
상기 리브(30)는 상기 상판부(10) 및 하판부(20) 사이에 복수개로 구비된다.The rib 30 is provided in plural between the upper plate portion 10 and the lower plate portion 20.
이러한 복수개의 리브(30)는 상기 상판부(10)와 하판부(20) 사이에 좌우방향으로 일정간격을 이루어 배열되며, 배열된 각각의 리브(30)는 전후방향으로 나란하게 연장된다.The plurality of ribs 30 are arranged at regular intervals in the horizontal direction between the upper plate portion 10 and the lower plate portion 20, and each of the ribs 30 arranged side by side extends in the front-rear direction.
따라서, 이렇게 배열된 복수개의 리브(30) 사이사이에는 전후방향으로 연장되는 중공의 골부(40)가 형성되게 된다.Therefore, the hollow valley part 40 extending in the front-back direction is formed between the plurality of ribs 30 arranged in this way.
위와 같은 구성은 통상적인 플라스틱 골판지의 구성과 동일하며, 본 발명은 전후방향으로 연장되는 상기 골부(40)를 분할시키는 골분할부(50)를 더 포함한다.The configuration as described above is the same as the configuration of a conventional plastic corrugated cardboard, the present invention further comprises a bone splitting portion 50 for dividing the bone portion 40 extending in the front and rear direction.
상기 골분할부(50)는 도 1 및 도 3에 일 예시된 것처럼, 상판부(10) 및 하판부(20)에 형성되는데, 상판부(10) 및 하판부(20)의 대응하는 일부분이 상호 대면하도록 가압에 의해 함몰되면서 함몰된 부분이 상호 접합되도록 열융착됨으로써 형성될 수 있으며, 이렇게 형성되는 골분할부(50)는 리브(30)와 골부(40)를 일정한 길이로 가로지르는 형태로 이루어질 수 있다.The bone division 50 is formed in the upper plate portion 10 and the lower plate portion 20, as illustrated in Figure 1 and 3, so that the corresponding portion of the upper plate portion 10 and the lower plate portion 20 face each other. The recessed portion by pressing may be formed by thermal fusion so that the recessed portions are joined to each other, and the bone splitting portion 50 formed as described above may be formed to cross the rib 30 and the valley portion 40 to a predetermined length.
그리고, 이러한 골분할부(50)는 상판부(10)와 하판부(20)에 전후방향을 따라 일정간격으로 배열되는 복수 개로 이루어질 수 있다.In addition, the bone splitting part 50 may be formed of a plurality of upper plate portion 10 and the lower plate portion 20 are arranged at regular intervals along the front and rear directions.
이렇게 골분할부(50)가 형성되면, 도 3에 일 예시된 것과 같이, 전후방향으로 연장된 상기 중공의 골부(40)가 전후방향으로 일정간격마다 골분할부(50)에 의해 막히면서 분할이 이루어짐으로써 골부(40)가 다수의 밀폐된 구조로 변형이 이루어진다.When the bone division portion 50 is formed in this way, as illustrated in FIG. 3, the hollow bone portion 40 extending in the front-rear direction is blocked while being divided by the bone division portion 50 at regular intervals in the front-rear direction. The bone 40 is deformed into a plurality of closed structures.
따라서, 골판지(100)에는 상판부(10)와 하판부(20) 사이에 다수의 밀폐된 공기층(A)이 생성됨으로써 골판지(100)의 물리적 강도를 증강시킴과 함께, 완충력이나 방음효과 또한 향상시킬 수 있게 된다.Therefore, the corrugated cardboard 100 is provided with a plurality of sealed air layers A between the upper plate portion 10 and the lower plate portion 20 to enhance the physical strength of the corrugated cardboard 100, and also to improve the buffering and soundproofing effects. It becomes possible.
즉 본 발명은 상판부(10)와 하판부(20) 및, 리브(30)와 골부(40)를 갖는 골판지(100) 자체에 골부(40)를 다수의 밀폐된 구조로 변형시키는 골분할부(50)가 형성됨으로써 단수의 골판지(100) 그 자체의 물리적 강도, 완충력 등을 향상시키는 것이다.That is, in the present invention, the bone splitting part 50 which deforms the bone part 40 into a plurality of closed structures in the cardboard 100 itself having the upper plate part 10 and the lower plate part 20, and the ribs 30 and the bone part 40. ) Is formed to improve the physical strength, buffering force and the like of the single corrugated cardboard 100 itself.
여기서, 상기 골분할부(50)는 도 4에 일 예시된 것처럼, 골판지(100) 전체의 리브(30)와 골부(40)를 가로지르는 길이로 형성되어 하나의 열로 구성되는 것도 가능하며, 도 1 및 도 2에 일 예시된 것처럼, 좌우방향으로도 배열되어 다수의 열로 구성되면서 좌우방향으로 배열된 각 열의 골분할부(50)는 상호 간에 좌우방향으로 나란하게 배열되는 것이 아니라 서로 어긋나도록, 즉 지그재그 형태를 이루어 배열되는 것이 가능하다.Here, the bone division portion 50 is formed as a length across the ribs 30 and the bone portion 40 of the entire cardboard 100, as illustrated in Figure 1, it is also possible to be configured in one row, Figure 1 As shown in FIG. 2, the bone dividing portions 50 of the columns arranged in the left and right directions while being arranged in the left and right directions are not arranged side by side in the left and right direction, but zigzag. It is possible to arrange in form.
상기 도면들에는 좌우방향을 따라 총 3열로 구성되면서 각 열의 골분할부(50)가 지그재그 형태로 배열된 것이 일 예시되어 있다.In the drawings, the bone splitting part 50 of each row is arranged in a zigzag form while being configured in a total of three rows along the left and right directions.
위와 같이 골분할부(50)가 다수의 열로 배열되면서 각 열의 골분할부(50)가 지그재그 형태를 이루게 되면, 그만큼 골분할부(50)의 좌우방향 길이를 짧게 할 수 있으므로 제조시 가압 함몰을 통한 골분할부(50)의 성형이 보다 용이하며, 또한 지그재그 형태로 배열됨으로써 골분할부(50)의 형성으로 인한 골판지(100)의 파손이나 절단의 위험성 또한 최소화시킬 수 있게 된다.When the bone splitting part 50 is arranged in a plurality of rows as described above, and the bone splitting part 50 of each row forms a zigzag shape, the bone splitting part through pressure depression during manufacturing may be shortened by the length of the bone splitting part 50. Molding of the 50 is easier, and also arranged in a zigzag form, it is possible to minimize the risk of breakage or cutting of the corrugated cardboard 100 due to the formation of the bone division (50).
