It is used as a main material for disposable products because of its low price, strength, heat resistance, Excellent cold resistance, etc.

PP는 에틸렌과 비슷하고 탄소 원자가 하나 많은 프로필렌을 중합시키면 폴리에틸렌보다 투명하고 굴절에 강한 폴리프로필렌이 만들어지고 투명하고 결정성이며, 내마모성, 내수성, 내약품성이 뛰어나다.PP, which is similar to ethylene and polymerizes propylene with many carbon atoms, makes polypropylene more transparent and resistant to refraction than polyethylene, is transparent and crystalline, and has excellent abrasion resistance, water resistance, and chemical resistance.

PVC는 에틸렌에서 하나의 수소 원자가 염소로 치환된 염화비닐의 중합체로, 가소제와 같은 첨가제와 혼합하여 가공성을 높일 수 있고, 단단한 파이프 소재부터 유연한 전선 피복, 인조가죽 등 넓은 범위의 용도에 쓰이며, 열가소성 플라스틱으로 우수한 내구성, 가공성, 발색성을 가진다.PVC is a polymer of vinyl chloride in which one hydrogen atom is substituted with chlorine in ethylene, and can be mixed with additives such as plasticizers to improve processability, and is used for a wide range of applications, from hard pipe materials to flexible wire coverings, artificial leather, etc. Made of plastic, it has excellent durability, processability, and color development.

PS는 스티렌의 라디칼 중합으로 얻어지는 비결정성의 무색 투명한 열가소성 수지로, 플라스틱 중에서 가장 가공하기 쉽고 높은 굴절률을 가지는데, 투명하고 빛깔이 아름다울 뿐만 아니라 전기절연성 매우 양호하며, 흡습성은 거의 없고 발포제를 써서 팽창시킨 스폰지상의 폴리스티렌은 매우 경량으로 단열재, 흡음재에 사용된다.PS is an amorphous, colorless, transparent thermoplastic resin obtained by radical polymerization of styrene. It is the easiest to process among plastics and has a high refractive index. It is not only transparent and beautiful in color, but also has excellent electrical insulation, little hygroscopicity, and uses a foaming agent. The expanded sponge-like polystyrene is very lightweight and is used for insulation and sound absorbing materials.

기술된 바와 같이 블로우 사출 가능한 HDPE, PP, PVC, PS 각각의 특성을 고려하여 장화를 최소 1겹 내지 최대 4겹까지 구성함으로써 강도, 내열성, 내한성, 내마모성, 전기절연성, 내수성, 내약품성, 가공성, 발색성, 경량화 등의 기능을 장화에 선택적으로 부여할 수 있게 된다.Strength, heat resistance, cold resistance, abrasion resistance, electrical insulation, water resistance, chemical resistance, processability, by configuring the boots up to a minimum of 1 ply to a maximum of 4 ply considering the characteristics of each blowable HDPE, PP, PVC, PS as described It is possible to selectively impart functions such as color development and weight reduction to the boots.

또한, 장화의 소재로 사용되는 상기 HDPE, PP, PVC, PS이 Argo-polymer 또는 Biopolyester를 함유하도록 할 수 있는데, 전자의 경우는 감자, 나무, 식물성, 동물성 단백질에서 찾아볼 수 있는 녹말과 같은 다당류를 포함(다당류는 단당류의 글루코오스 결합으로 구성되고, 단백질은 다양한 그룹에 포함되어 있는 아미노산으로 구성되며, 이러한 아미노산들은 축합반응에 의해 합쳐지며 펩타이드 결합을 형성함)하고, 후자의 경우는 폴리 하이드록시 뷰테이트와 PLA(Polylactic acid)를 포함하여, 본 발명의 일회용 장화가 사용 이후로 폐기될 시에 가급적 자연스럽게 대기 중에서 분해되는 시간을 단축시킬 수 있게 된다.In addition, the HDPE, PP, PVC, and PS used as the material of the rain boots may contain Argo-polymer or Biopolyester. In the former case, polysaccharides such as starch found in potato, wood, vegetable, and animal proteins (Polysaccharides are composed of monosaccharide glucose bonds, proteins are composed of amino acids contained in various groups, and these amino acids are combined by condensation reaction to form peptide bonds), and in the latter case, polyhydroxy Including the butate and polylactic acid (PLA), it is possible to shorten the time to decompose in the air as naturally as possible when the disposable boots of the present invention are disposed of after use.

이하에서는, 본 발명에 따른 블로우 사출을 사용한 일회용 장화(10)의 구조적 변형 사례에 대해 살펴보기로 한다.Hereinafter, a structural modification example of the disposable rain boots 10 using the blow injection according to the present invention will be described.

우선적으로, 본 발명의 일회용 장화(10)는 착용자별 맞춤형 길이 조절을 위해 착용 방향을 기준으로 상부에 하나 이상의 제1 수평 절단선(11)을 갖도록 사출 이후 가공처리되고, 제1 수평 절단선(11)을 기준으로 외력에 의해 제거 가능한 제1 수평 절단 부위(12)를 구비할 수 있다.First of all, the disposable rain boots 10 of the present invention are processed after injection so as to have at least one first horizontal cutting line 11 on the top based on the wearing direction for adjusting the length customized for each wearer, and the first horizontal cutting line ( 11) may be provided with a first horizontal cutting portion 12 that can be removed by an external force as a reference.

상기와 같은 구조에 따르면, 사람마다 성별, 연령대별로 신장이 제각각 상이하기 때문에 1개 블로우 금형에서 사출하여 일괄적인 크기의 장화 착용 시 여성, 어린이에게는 사이즈가 커서 이동하는데 불편할 수 있는 점을 감안하여 제1 수평 절단선(11)을 따라 사람의 손으로 제1 수평 절단 부위(12)를 쉽게 제거함으로써 착용자 맞춤형태로 장화(10) 길이를 조절할 수 있기 때문에, 결과적으로 본인이 희망하는 수준의 크기로 장화를 착용하여 활동하기 편리하도록 기능하게 된다.According to the structure as described above, since each person has different heights for each gender and age group, it is manufactured in consideration of the fact that it is inconvenient for women and children to move and wear large size boots by injecting from one blow mold. 1 Since the first horizontal cutting part 12 can be easily removed by a human hand along the horizontal cutting line 11, the length of the boots 10 can be adjusted in the form of a wearer's fit. Wearing rain boots will function as a convenient activity.

또한, 상기 제1 수평 절단 부위(12)의 수직방향으로 수직 절단선(13)이 구비되고 제1 수평 절단 부위(12) 아래로 수평 방향을 따라 복수개의 펀칭홀(14)이 형성되도록 하여, 제1 수평 절단 부위(12)는 수직 절단선(13)을 기준으로 절단되면서 밴드 형상을 갖게 되고, 밴드(15)는 펀칭홀(14)을 관통하여 매듭지어져 착용자의 다리에 고정 가능하도록 할 수 있다.In addition, a vertical cutting line 13 is provided in the vertical direction of the first horizontal cutting portion 12 and a plurality of punching holes 14 are formed along the horizontal direction below the first horizontal cutting portion 12, The first horizontal cutting portion 12 has a band shape while being cut on the basis of the vertical cutting line 13, and the band 15 can be knotted through the punching hole 14 to be fixed to the wearer's leg. have.

이는 장화 상부가 착용자 다리에 고정되지 않은 상태에서는 착용자가 움직이는 과정에서 장화가 벗겨질 수 있기 때문에 이러한 상황을 방지하기 위한 것으로, 착용자가 희망하는 장화 길이에 맞추어 제1 수평 절단선(11)을 따라 제1 수평 절단 부위(12)를 제거한 다음으로 제1 수평 절단 부위(12)에 형성된 수직 절단선(13)을 손으로 잡아당기면 제1 수평 절단 부위(12)가 형상 가변적인 밴드(15) 형태가 되고, 수평방향으로 펀칭홀(14)을 따라 내측 및 외측으로 이러한 밴드(15)를 교차 삽입한 이후 밴드(15) 끝단을 착용자 다리에 매듭지음으로써 장화(10)가 착용자로부터 안정적으로 고정된 상태를 유지할 수 있게 된다.This is to prevent this situation because the upper portion of the boots are not fixed to the wearer's legs, the boots may come off during the movement of the wearer, along the first horizontal cutting line 11 according to the length of the boots desired by the wearer After removing the first horizontal cut portion 12, if the vertical cut line 13 formed on the first horizontal cut portion 12 is pulled by hand, the first horizontal cut portion 12 is in the form of a shape variable band 15 After being cross-inserted such a band 15 inward and outward along the punching hole 14 in the horizontal direction, the boots 10 are stably fixed from the wearer by knotting the end of the band 15 on the wearer's leg. You will be able to maintain state.

한편으로, 본 발명에 따른 장화(10)는 실내 환경에서는 이동하는데 큰 문제는 없으나 바닥면이 마찰계수가 작은 합성수지로 되어 있어 예로써 등산과 같은 야외 활동 중에 빗물에 젖은 물체(암석, 대리석 등) 위에서 장화가 미끌어지기 쉬워 큰 부상을 당할 위험성이 높기 때문에, 이러한 문제점을 방지할 목적으로 본 발명에 따른 장화(10)는 착용 방향을 기준으로 하부에 제2 수평 절단선(16)을 갖도록 사출 이후 가공처리되고, 제2 수평 절단선(16)을 기준으로 외력에 의해 제거 가능한 제2 수평 절단 부위(17)를 구비하여 착용자의 신발 바닥이 지면과 직접적으로 접촉 가능하도록 할 수 있다.On the other hand, the rain boots 10 according to the present invention do not have a big problem in moving in an indoor environment, but the floor surface is made of synthetic resin with a small friction coefficient, so for example, objects wet with rain (rock, marble, etc.) during outdoor activities such as mountaineering. Since the boots are easily slipped from above, and there is a high risk of being injured, the boots 10 according to the present invention for the purpose of preventing such problems are injected after having the second horizontal cutting line 16 at the bottom based on the wearing direction. A second horizontal cutting portion 17 that is processed and removed by external force based on the second horizontal cutting line 16 may be provided so that the bottom of the wearer's shoe can directly contact the ground.

장화를 착용한 다음으로 이동하는 과정에서 신발 바닥과 지면의 마찰력에 의해 자연스럽게 장화 바닥면이 벗겨지면서 신발 바닥과 지면이 바로 접촉될 수도 있으나, 이를 위해서는 반드시 장화 바닥면이 닳도록 착용자가 이동하는 시간이 필요로 되고 그 시간동안 미끌림 현상으로 인한 위험을 감내해야 하지만, 기술된 바와 같은 구조에 의하면 장화 착용 전후로 제2 수평 절단선(16)을 따라 손을 사용하여 제2 수평 절단 부위(17)를 장화로부터 쉽게 분리하게 되면 즉시 착용자 신발 바닥과 지면이 직접 접촉하게 되어짐으로 인해 장화 착용으로 인한 미끌림 사고를 미연에 방지할 수 있게 된다.In the process of moving to the next place after wearing the boots, the bottom of the boots may come into contact with the bottom of the shoes naturally due to the frictional force between the bottom of the shoes and the ground, but for this, the time for the wearer to move so that the bottom of the boots is worn out This is necessary and the risk of slipping during that time must be taken, but according to the structure as described, the second horizontal cutting part 17 is used by hand along the second horizontal cutting line 16 before and after wearing the boots. When it is easily separated from the boots, it is possible to prevent slippage accidents caused by wearing the boots by directly contacting the bottom and the ground of the shoes of the wearer.

여기서, 상기 제2 수평 절단 부위(17)는 장화로부터 분리된 후에 폐기되어야 하지만, 산과 같은 야외 장소에 함부로 폐기물을 버리는 것은 자연을 훼손시키는 악영향을 끼칠 수 있기 때문에, 장화로부터 제거된 제2 수평 절단 부위(17)를 펀칭홀(14)로 관통시켜 장화 상부에 보관 가능하도록 함으로써 나중에 장화를 폐기처리할 때 제2 수평 절단 부위(17) 또한 함께 버릴 수 있을 것이다.Here, the second horizontal cutting part 17 should be disposed of after being separated from the boots, but throwing waste in an outdoor place such as a mountain can adversely affect nature, so the second horizontal cutting removed from the boots The second horizontal cutting site 17 may also be discarded when the boots are disposed of later by allowing the site 17 to pass through the punching hole 14 so as to be stored on the top of the boots.
