Description

친환경 성형재 및 그를 이용한 성형 제품Eco-friendly molding materials and molding products using the same
본 발명은 성형 제품에 관한 것으로, 더욱 상세하게는 옥수수 소재를 기반으로 하는 친환경 성형재 및 그를 이용한 성형 제품에 관한 것이다.The present invention relates to a molded product, and more particularly, to an eco-friendly molded material based on a corn material and a molded product using the same.
일반적으로 성형 제품은 플라스틱 소재의 성형재를 이용한 성형 공정을 통하여 제조된다. 예컨대 성형 제품은 수저, 포크, 젓가락, 육묘용 포트 등과 같은 일회용 제품을 포함할 수 있다.In general, a molded product is manufactured through a molding process using a molding material of a plastic material. For example, the molded product may include disposable products such as spoons, forks, chopsticks, pots for seedlings, and the like.
여기서 육묘용 포트는 작물의 재배에 이용된다. 일반적으로 비닐하우스와 같은 시설에서 재배되는 작물은 지면에 묘상을 만들어 작물을 재배하는 토경 재배 방법이 이용된다. 그러나, 이러한 토경 재배는 생산성이 떨어지고, 묘상이 바닥에 펼쳐져 있기 때문에 공간을 활용할 수 없다는 단점을 가지고 있다.Here, the pot for seedling is used for growing crops. In general, for crops grown in facilities such as plastic greenhouses, the soil cultivation method of growing crops by making seedbeds on the ground is used. However, this soil cultivation has disadvantages in that productivity is low and the space cannot be utilized because the seedlings are spread out on the floor.
최근에는, 이러한 문제점을 해결하기 위하여 육묘용 포트를 활용하는 재배 방법이 주로 이용되고 있다. 육묘용 포트는 소규모의 공간에서 집약적인 관리가 가능한 것으로서, 다수개의 단위 포트가 종횡으로 일렬 배치된 구조를 가진다.Recently, in order to solve this problem, a cultivation method using a pot for seedlings is mainly used. The pot for seedling can be managed intensively in a small space, and has a structure in which a plurality of unit ports are arranged vertically and horizontally.
하지만 종래의 육묘용 포트는 주로 PE(polyethylene), PP(polypropylene), PS(polystyrene) 등의 재질로 제조됨으로써, 유해성분이 다량 함유되어 있다. 따라서, 인체 및 작물에 악영향을 초래할 수 있을 뿐만 아니라 심각한 환경오염을 초래하고 있다.However, the conventional pot for seedling is mainly made of materials such as PE (polyethylene), PP (polypropylene), PS (polystyrene), and contains a large amount of harmful components. Therefore, it may cause adverse effects on the human body and crops, as well as cause serious environmental pollution.
또한, 육묘용 포트의 소재로서, 환경오염을 초래하는 유해성분의 규제가 엄격해짐에 따라, 향후에는 유해성분이 다량 함유된 종래의 재질의 사용이 불가할 수 있다.In addition, as a material for a pot for seedlings, as regulations on harmful components that cause environmental pollution become stricter, it may not be possible to use conventional materials containing a large amount of harmful components in the future.

[제1 실시예][First embodiment]
도 1은 본 발명의 제1 실시예에 따른 친환경 성형재를 이용한 육묘용 포트를 보여주는 평면도이다. 도 2는 도 1의 2-2선 단면도이다. 그리고 도 3은 도 2의 A 부분의 확대도이다.1 is a plan view showing a pot for seedling using an eco-friendly molding material according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1 . And FIG. 3 is an enlarged view of part A of FIG. 2 .
도 1 내지 도 3을 참조하면, 제1 실시예에 따른 육묘용 포트(100)는 친환경 성형재를 이용한 성형 공정으로 제조된다.1 to 3, the pot 100 for seedlings according to the first embodiment is manufactured by a molding process using an eco-friendly molding material.
제1 실시예에 따른 육묘용 포트(100)의 성형 방법으로는 성형 금형에 친화경 성형재를 투입한 후 가열 연화한 시트로 제조한 후, 시트를 진공의 압력차를 이용하여 제조한다. 이러한 성형 방법은 진공 성형 방법으로서, 면적에 비해 얇은 두께로 제1 실시예에 따른 육묘용 포트(100)를 제조할 수 있다.In the molding method of the pot 100 for seedlings according to the first embodiment, an affinity molding material is put into a molding mold, and then a sheet softened by heat is prepared, and then the sheet is manufactured using a vacuum pressure difference. This forming method is a vacuum forming method, and it is possible to manufacture the pot 100 for seedlings according to the first embodiment with a thin thickness compared to the area.
이와 같이 제1 실시예에 따른 육묘용 포트(100)는 친환경 소재를 기반으로 친환경 성형재로 제조되기 때문에, 인체 및 작물에 악영향을 주거나 환경오염을 발생되는 것을 억제할 수 있다.As described above, since the pot 100 for seedling according to the first embodiment is made of an eco-friendly molding material based on an eco-friendly material, it is possible to suppress adverse effects on the human body and crops or from generating environmental pollution.
이와 같은 제1 실시예에 따른 육묘용 포트(100)는 복수의 단위 포트와, 복수의 단위 포트를 연결하며 복수의 단위 포트를 개별로 분리할 수 있도록 노치(30)가 형성된 절단 영역(20)을 포함한다.The pot 100 for seedling according to the first embodiment as described above has a plurality of unit ports and a plurality of unit ports, and a cutting area 20 in which a notch 30 is formed so that the plurality of unit ports can be individually separated. includes
단위 포트는 다양한 형상으로 성형이 가능하다. 제1 실시예에 따른 단위 포트들은 절단 영역(20)을 매개로 사각형 격자 형태로 배열되게 형성된 예를 개시하였다.The unit pot can be molded into various shapes. An example in which the unit ports according to the first embodiment are formed to be arranged in a rectangular grid shape via the cut region 20 is disclosed.
절단 영역(20)은 단위 포트들을 연결하여 지지하는 프레임의 기능을 담당한다. 그리고 절단 영역(20)으로 연결된 단위 포트들을 개별 단위 포트로 쉽게 분리할 수 있도록, 절단 영역(20)을 따라서 노치(30)가 형성되어 있다.The cut region 20 is responsible for the function of a frame supporting the unit ports by connecting them. In addition, a notch 30 is formed along the cutting region 20 so that the unit ports connected to the cutting region 20 can be easily separated into individual unit ports.
노치(30)는 영문자 "V"자형으로 홈으로 형성될 수 있다. 사용자는 육묘용 포트(100)에서 단위 포트를 분리할 때, 분리할 단위 포트를 중심으로 노치(30)가 절단될 수 있도록 상하로 절단 영역(20)을 구부림으로써 해당 단위 포트를 분리할 수 있다.The notch 30 may be formed as a groove in an English letter “V” shape. When the user separates the unit port from the port 100 for seedling, the unit port can be separated by bending the cutting area 20 up and down so that the notch 30 can be cut around the unit port to be separated. .
이러한 노치(30)는 제1 실시예와 같이 절단 영역(20)의 상부에 형성할 수 있다. 또는 노치(30)는 절단 영역(20)의 하부에 형성될 수 있다. 또는 노치(30)는 절단 영역(20)의 상부 및 하부에 함께 형성될 수 있다The notch 30 may be formed in the upper portion of the cut region 20 as in the first embodiment. Alternatively, the notch 30 may be formed in the lower portion of the cut region 20 . Alternatively, the notch 30 may be formed together in the upper and lower portions of the cut region 20 .
노치(30)는 육묘용 포트(100)의 형상을 유지하면서 필요한 경우 절단할 수 있도록 절단 영역(20)에 적절한 깊이로 형성될 수 있다. 즉 절단 영역(20)의 두께(L1)에 노치(30)의 깊이(L2)의 비율이 0.3 내지 0.7 되게 노치(30)를 형성할 수 있다.The notch 30 may be formed to an appropriate depth in the cutting area 20 so as to be cut if necessary while maintaining the shape of the pot 100 for seedling. That is, the notch 30 may be formed so that the ratio of the depth L2 of the notch 30 to the thickness L1 of the cut region 20 is 0.3 to 0.7.
여기서 노치(30)의 비율이 0.3 이하인 경우, 절단 영역(20)을 따라서 단위 포트가 잘 분리되지 않을 수 있다. 반대로 노치(30)의 비율이 0.7을 초과하게 되면, 단위 포트의 분리가 필요하지 않은 일반적으로 육묘용 포트(100)를 취급하는 과정에서 절단 영역(20)이 분리되는 문제가 발생할 수 있다.Here, when the ratio of the notch 30 is 0.3 or less, the unit port may not be well separated along the cutting area 20 . Conversely, if the ratio of the notch 30 exceeds 0.7, there may be a problem in that the cutting area 20 is separated in the process of handling the pot 100 for seedlings in general, which does not require separation of the unit pot.
제1 실시예에 따른 육묘용 포트(100)는 절단 영역(20)의 노치(30)에 채워지는 보강재(40)를 더 포함할 수 있다. 즉 절단 영역(20)에 노치(30)만을 형성할 경우, 육묘용 포트(100)가 노치(30)를 중심으로 쉽게 휨이 발생한다. 즉 노치(30)로 인해 육묘용 포트(100)의 유연성이 증가하기 때문에, 육묘용 포트(100)를 운반할 때 중간 부분이 아래로 처지는 등의 문제가 발생할 수 있다. 심한 경우, 단위 포트의 분리가 필요하지 않은 일반적으로 육묘용 포트(100)를 취급하는 과정에서 절단 영역(20)이 분리되는 문제가 발생할 수 있다.The pot 100 for seedling according to the first embodiment may further include a reinforcing material 40 filled in the notch 30 of the cutting region 20 . That is, when only the notch 30 is formed in the cut region 20 , the pot 100 for seedling easily bends around the notch 30 . That is, since the flexibility of the pot 100 for seedling increases due to the notch 30, problems such as drooping down in the middle part when transporting the pot 100 for seedling may occur. In severe cases, there may be a problem in that the cutting area 20 is separated in the process of handling the pot 100 for seedlings in general, which does not require separation of the unit pot.
하지만 제1 실시예와 같이 보강재(40)로 노치(30)를 채움으로써, 절단 영역(20)의 경도를 증가시킬 수 있다. 이로 인해 육묘용 포트(100)를 운반할 때 중간 부분이 아래로 처지는 문제를 억제할 수 있다. 단위 포트의 분리가 필요하지 않은 일반적으로 육묘용 포트(100)를 취급하는 과정에서 절단 영역(20)이 분리되는 문제를 억제할 수 있다.However, by filling the notch 30 with the reinforcing material 40 as in the first embodiment, the hardness of the cut region 20 can be increased. Due to this, it is possible to suppress the problem that the middle portion sags down when transporting the pot 100 for seedlings. In general, it is possible to suppress the problem that the cutting area 20 is separated in the process of handling the pot 100 for seedlings that do not require separation of the unit pot.
보강재(40)로는 노치(30)로부터 쉽게 분리할 수 있는 접착성이 약한 플라스틱 소재, 예컨대 친환경 소재 또는 생분해성 소재가 사용될 수 있다.As the reinforcing material 40 , a plastic material with weak adhesion that can be easily separated from the notch 30 , for example, an eco-friendly material or a biodegradable material may be used.
이와 같이 제1 실시예에 따른 육묘용 포트(100)는 단위 포트들을 구분하는 절단 영역(20)에 노치(30)를 형성하고, 노치(30)에 보강재(40)로 채움으로써, 육묘용 포트(100)를 취급하는 과정에서 절단 영역(20)을 따라서 단위 포트가 임의적으로 분리되는 문제를 해소할 수 있다.As described above, the pot 100 for seedling according to the first embodiment forms a notch 30 in the cut region 20 that separates unit ports, and fills the notch 30 with a reinforcing material 40, so that the pot for seedling It is possible to solve the problem that the unit port is arbitrarily separated along the cutting area 20 in the process of handling (100).
물론 단위 포트의 분리가 필요한 경우에는, 절단 영역(20)을 중심으로 이웃하는 단위 포트를 상하로 구부림으로써, 단위 포트를 쉽게 분리할 수 있다.Of course, when separation of the unit port is necessary, the unit port can be easily separated by bending the neighboring unit ports up and down around the cutting area 20 .
