Description

용해성 작은 주머니(sachet)Soluble small sachet

본 발명은 수용성 또는 수본산성 재료로된 봉투에 담겨진 액체상 화학약품, 또는 액체나 겔에 용해 또는분산된 화학약품을 함유하는 포장체에 만한 것이다.The present invention is directed to a package containing a liquid chemical contained in an envelope made of a water-soluble or water-soluble acidic material, or a chemical dissolved or dispersed in a liquid or gel.

현재에는, 대부분의 유해한 액체들이 금속드럼, 또는 소량이 요구될 경우 플라스틱 용기에 보관되고 있다.Currently, most hazardous liquids are stored in metal drums or plastic containers when small amounts are required.

유해한 화합물, 특히 농화학적 화합물은 다양한 방법에 의해 제제된다. 그러나, 이러한 화합물을 농부들이 취급하기에는 액체 형태인 것이 특히 바람직하다. 이는 화합물의 도포를 쉽게 한다. 그러나, 액체를 취급하는데는 어려움과 단점이 따른다. 액체는 땅에 엎질러지거나 용기의 구멍으로 인해 샐 수도 있다. 또한 용기는 물리적 충격을 받으면 파괴될 수도 있다.Harmful compounds, especially agrochemical compounds, are formulated by a variety of methods. However, it is particularly desirable that the compound is in liquid form for farmers to handle. This makes the application of the compound easy. However, there are difficulties and disadvantages in handling liquids. The liquid may spill on the ground or leak due to a hole in the container. The container may also be destroyed upon physical impact.

따라서, 농부에게 적합하고, 용기를 취급하는 모든 경우에 있어 안전하며, 환경에도 안전한 용기 시스템을 고안하기는 어렵다.Therefore, it is difficult to devise a container system suitable for farmers, safe in all cases of handling the container, and environmentally safe.

농약을 필름으로 만들어진 용해성 백 또는 작은 주머니에 담을 수 있다는 것은 공지이다. 그러나, 이러한 필름은 파손 또는 파열되어, 그안에 담겨진 농약이 엎지러질 수 있다. 사실상, 필름에 존재할 수도 있는 여러가지 단점에 의하여 필름이 취약해지고, 결과적으로 누출의 주된 원인이 될 수 있다.It is known that pesticides can be contained in soluble bags or small bags made of film. However, such films may break or rupture, causing the pesticide contained therein to spill. In fact, the film is vulnerable to the various disadvantages that may exist in the film, which can be a major cause of leakage.

공기 방울, 먼지입자 또는 이물질, 겔 입자 또는 필름 내부 또는 표면의 얇은 부위 등의 존재가 모두 상당한 약점이 된다. 이러한 약점을 가진 필름을 여러번 취급하거나 물리적 충격을 주면, 필름은 그 지점에서 상할 것이다. 이는 특히 용기를 상인이나 농부가 거칠게 혹은 불만하게 다룰 경우에 문제가 된다.The presence of air bubbles, dust particles or foreign matter, gel particles or thin areas inside or on the film are all significant drawbacks. If the film with this weakness is handled multiple times or given a physical impact, the film will be damaged at that point. This is especially a problem when the container is dealt with roughly or dissatisfied by the merchant or farmer.

상기 언급한 필름의 취약성은, 필름의 제조방법에 따라 특정 종류의 필름에 더 많이 혹은 더 적게 존재한다. 필름을 주조에 의해 만들었을 경우에, 구멍은 보다 적을 수 있지만 겔 함유물의 작은 조각이 보다 빈번하게 존재한다. 필름을 압출에 의해 제조할 경우에는 구멍이 보다 많다.The fragility of the aforementioned films is more or less present in certain types of film depending on the method of making the film. When the film is made by casting, the holes may be smaller but more small pieces of gel content are present. When the film is produced by extrusion, there are more holes.

본 발명은 취급이 안전한 새로운 농약용 용기 시스템을 제공하려는 것이다.The present invention seeks to provide a new pesticide container system that is safe to handle.

또한 본 발명은 최종 수요자(예를들면 농부)가 취급하기 용이한 새로운 농약용 용기 시스템을 제공하려는것이다.It is also an object of the present invention to provide a new pesticide container system that is easy for end users (eg farmers) to handle.

더나아가서 본 발명은 오염 및 환경 파괴의 위험이 감소된 새로운 농약용 용기 시스템을 제공하려는 것이다.Furthermore, the present invention seeks to provide a new pesticide container system with reduced risk of pollution and environmental degradation.

한 국면에서 볼때, 본 발명은 필름 용기 시스템의 구멍을 통하여 액상 또는 용해된 상태의 화학약품이 누출되는 것을 방지하기 위한 것이다. 구멍은 일반적으로 드물게 존재하지만, 수천개의 용기 중에 하나의 구멍만이 존재한다할지라도, 용기 내의 액체가 구멍을 통과하여 주위 환경을 오염시키기 때문에 해를 입히는데 충분하다.In one aspect, the invention is intended to prevent leakage of chemicals in liquid or dissolved state through the apertures of the film container system. Holes are generally rare, but even if only one hole is present in thousands of containers, it is sufficient to cause harm because liquid in the container passes through the hole and contaminates the surrounding environment.

본 발명의 다른 목적 및 장점은 이하의 설명으로부터 명백해질 것이다.Other objects and advantages of the present invention will become apparent from the following description.

본 발명의 용기 시스템은 액체 또는 겔 형태의 유해물질이 라미네이트 필름으로 만들어진 수용성 또는 수분산성 주머니에 담기는 것을 특징으로 한다.The container system of the present invention is characterized in that the hazardous substance in liquid or gel form is contained in an aqueous or water dispersible pouch made of laminate film.

본 발명의 바람직한 양상에 따로면, 유해 화합물은 살충제, 식물보호제 또는 식물성장 조절제 등과 같은 농약이다.According to a preferred aspect of the present invention, the harmful compound is a pesticide such as an insecticide, a plant protection agent or a plant growth regulator.

따라서, 본 발명은 수용성 또는 수분산성 라미네이트 필름에 담긴, 액체나 겔에 용해 또는 분산된 유해화학물질을 함유하는 포장체를 제공한다.Accordingly, the present invention provides a package containing harmful chemicals dissolved or dispersed in a liquid or a gel contained in a water-soluble or water-dispersible laminate film.

본 명세서에서 "라미네이트 필름"이라는 용어는 둘 이상의 원래 분리되었던 충으로부터 한데 결합되어 만들어진 필름을 의미한다. 층들은 공지의 방법에 의해 라미네이트에서 한데 결합된다. 예를들어 층 또는 라미네이트는 압축, 가열, 가교형성, 융합, 접착 또는 그들의 임의 조합에 의해 결합될 수 있다. 층간의 접착은 별도의 접착제를 이용하거나, 적절하다면 물을 이용하여 수행될 수 있다.As used herein, the term "laminate film" refers to a film made by bonding together from two or more originally separated packs. The layers are joined together in a laminate by known methods. For example, the layers or laminates can be joined by compression, heating, crosslinking, fusion, adhesion or any combination thereof. The adhesion between the layers can be carried out using a separate adhesive or, if appropriate, water.

적절한 수용성 또는 수분산성 층을 사용할 경우, 라미네이트 필름을 수득하기 위한 특히 펀리한 방법은 각각의 층을 PVA접착제(일반적으로 저분자량의 것) 및/또는 더욱 간단하게는 물을 이용하여 접착시키는것이다.When using a suitable water soluble or water dispersible layer, a particularly funky way to obtain the laminate film is to adhere each layer with a PVA adhesive (generally low molecular weight) and / or more simply water.

라미네이트 필름을 제조하기 위해서는 둘이상의 층이 사용되기 때문에 필름에 구멍이 생길 수 있는 확률이 거의 0으로 감소된다. 이는 각개의 층에서 두개의 구멍이 겹쳐진다는 것은 있을 법하지 않기 때문이다. 더우기, 다층(예를들면 2층)필름의 인장 강도는 단일층으로 만들어진 같은 두꼐의 유사한 필름의 인장 강도보다 양호하다.Since more than one layer is used to make the laminate film, the probability of openings in the film is reduced to almost zero. This is because it is unlikely that two holes overlap in each layer. Moreover, the tensile strength of a multilayer (eg two layer) film is better than that of similar films of the same thickness made of a single layer.

본 발명에 사용되는 라미네이트 필름은 일반적으로 10∼250미크론, 바람직하게는 15∼80미크론의 두께를 갖는다. 본 발명에 사용되는 라미네이트 필름을 구성하는 각각의 층은 일반적으로 각각 이러한 형상의 1/2이다. 두개의 층이 사용될 경우, 두 층의 두께비는 일반적으로 0.1∼10, 바람직하게는 0.5∼2이다. 본 발명에 따르는 라미네이트 필름으로 만들어진 백이나 작은 주머니는 일반적으로 0.2∼12리터, 바람직하게는 0.45∼6리터의 용량을 가진다.The laminate film used in the present invention generally has a thickness of 10 to 250 microns, preferably 15 to 80 microns. Each layer constituting the laminate film used in the present invention is generally each one half of this shape. When two layers are used, the thickness ratio of the two layers is generally 0.1 to 10, preferably 0.5 to 2. Bags or small bags made of laminate films according to the invention generally have a capacity of 0.2 to 12 liters, preferably 0.45 to 6 liters.

본 발명에서 사용될 수 있는 재료는 담겨질 화학약품을 용해 또는 분산시키는데 사용되는 유기 용매에 불용성인 수용성 혹은 수분산성 재료이다. 적합한 재료로서는 폴리에틸렌 옥사이드 또는 메틸 셀룰로오스를 들 수 있으나, 상기 재료는 바람직하게는 폴리비닐 알코올을 함유하거나 그로부터 유도된 것, 즉 부분적으로 혹은 전체적으로 가알코올 분해 또는 가수분해된 것, 예를들면 40∼99%, 바람직하게는 70∼92%가 가알코올분해 또는 가수분해된 폴리비닐 아세테이트 필름이다.Materials that can be used in the present invention are water-soluble or water-dispersible materials that are insoluble in the organic solvents used to dissolve or disperse the chemicals to be contained. Suitable materials include polyethylene oxide or methyl cellulose, but the material preferably contains or is derived from polyvinyl alcohol, ie partially or totally hydrolyzed or hydrolyzed, for example 40-99. %, Preferably 70 to 92%, is a polyalcoholized or hydrolyzed polyvinyl acetate film.

본 발명의 라미네이트 필름층은 동일 또는 상이한 재료로 만들어질 수 있다. 상이한 재료의 층으로부터 제조된 필름이 유익한 성질을 가질 수 있다. 예를들어, 포장체의 내층은 담겨진 농약에 대해 보다 내성을 갖도록 만물어질 수 있다. 또한, 주머니의 외층은 하기에 나타낸 성질 중 하나 이상을 갖도록 선택될 수 있다.The laminate film layer of the present invention may be made of the same or different materials. Films made from layers of different materials may have beneficial properties. For example, the inner layer of the package can be made to be more resistant to the contained pesticides. In addition, the outer layer of the bag may be selected to have one or more of the properties shown below.

ⅰ. (내층또는 단일층 포장체에 비해)물에 보다 빨리 용해됨.Iii. Dissolves faster in water (compared to inner or single layer packages).

ⅱ. 기계적 손상에 대한 개선된 내성을 포함하는 개선된 기계적 성질.Ii. Improved mechanical properties, including improved resistance to mechanical damage.

ⅲ. 개선된 절삭성.Iii. Improved Machinability.

ⅳ. 상대습도에 대한 보다 적은 민감성.Iii. Less susceptibility to relative humidity.

ⅴ. 동결 및/또는 고온에 대한 내성Iii. Resistance to freezing and / or high temperatures

라미네이트 필름의 하나 이상의 층은 가소제를 함유해도 좋다. 내층중 적절한 가소제의 함량은 필를의 봉함성을 개선하고, 필름을 잘 늘어나지 않도록 한다. 따라서 필름을 기계에서 가공하고 유해 액체의 주워를 봉하기가 쉬워진다. 용기의 외층 중 적절한 가소제의 함량은 외표면을 보다 유연하게 하여 저온, 충격 또는이동으로 인한 물리적 손상에 더욱 내성을 갖도록 해준다.One or more layers of the laminate film may contain a plasticizer. The proper amount of plasticizer in the inner layer improves the sealability of the fill and prevents the film from stretching well. This makes it easier to process the film on the machine and seal up picking up of hazardous liquids. The proper amount of plasticizer in the outer layer of the container makes the outer surface more flexible, making it more resistant to physical damage due to low temperatures, shocks or movements.

라미네이트 필름의 층은 상이한 기술, 예를들면 압출 또는 주조를 이용하여 만들어질 수도 있다. 상이한방법에 의해 제조된 층으로 만들어진 라미네이트는 우수한 유연성, 증가된 강도 및 증가된 내연신성을 포함하는 유익한 성질을 가질 수 있다. 증가된 강도 및/또는 내연신성은 팔름의 한 방향에 대해서일 수 있다. 본 발명에서 사용되는 라미네이토 필름은 필름 결함으로 인하여 충전 과정 또는 이어지는 취급 도중에 누출되는 종전 기술의 포장체의 시간을 소모하는 유해한 결과를 방지하는 포장체를 제조하는데 사용된다.The layer of laminate film may be made using different techniques, such as extrusion or casting. Laminates made from layers made by different methods may have beneficial properties including good flexibility, increased strength and increased stretch resistance. Increased strength and / or stretch resistance can be with respect to one direction of the palm. The laminating film used in the present invention is used to produce a package that prevents the time consuming and harmful consequences of prior art packages leaking during the filling process or subsequent handling due to film defects.

이미 언급하였듯이, 주머니(또는 용기 시스템)는 액체나 겔을 담을 수 있다. 본 발명의 바람직한 양태는 겔을 함유하는 본 발명의 백 또는 용기 시스템이다.As already mentioned, the bag (or container system) may contain liquids or gels. A preferred embodiment of the present invention is the bag or container system of the present invention containing a gel.

본 발명의 특별한 양태에 따르면, 겔은 하기 성질 중 하나 이상을 갖도록 선택된다.According to a particular embodiment of the invention, the gel is selected to have one or more of the following properties.

*수득된는 겔이 연속적 시스템을 형성함 ; 및/또는 *수득되는 겔이 500∼50,000cps, 더욱 바람직하게는 1,000∼12,000cps의 점도(20rpm으로 회전하는 펀평한 판의 형테인 점도계로 실온에서 측정한 브루크필드점도)를 가짐 ; *겔이 조절된 전단 응력과 생성되는 전단왜곡(shear strain)의 상차이(phase difference)Φ를 tg(Φ)가 1.5이하, 바람직하게는 1.2이하가 되는 값으로 가짐. tg(Φ)는 각 Φ(또는 상 차이)의 기울기(tangent)이다. Φ의 측정은 편평한 고정판 및 상기 판 위의 회전 원추체(그 사이의 각은 10°미만, 바람직하게는 4°미만이다)을 갖는 레오미터를 이용하여 실온에서 수행된다. 그 원추체는 조절된 스피드 모터를 이용하여 회전되며 ; 회전은 사인곡선적(sinusoidal)이다. 즉, 토크와 각의 변위 변화가 시간에 대하여 사인함수이다. 이러한 각의 변위는 상기 언급한 전단 왜곡에 해당한다 ; 조절된 스피드 모터의 토크(이는 각의변위를 일으킨다)는 상기 언급한 조절된 전단응력에 해당한다 ; *겔이 l을 초과하는, 바람직하게는 1.1을 초과하는 밀도를 가짐 ; *겔이 75미만, 바람직하게는 25미만의 자발성(후술하는 바와같음)을 가짐.Obtained gels form a continuous system; And / or * the gel obtained has a viscosity of 500 to 50,000 cps, more preferably 1,000 to 12,000 cps (Brookfield viscosity measured at room temperature with a flat plate-type viscometer rotating at 20 rpm); The phase difference Φ of the gel-adjusted shear stress and the shear strain produced is such that tg (Φ) is less than 1.5, preferably less than 1.2. tg (Φ) is the tangent of each Φ (or phase difference). The measurement of Φ is carried out at room temperature using a rheometer having a flat stationary plate and a rotating cone on the plate (the angle between them is less than 10 °, preferably less than 4 °). The cone is rotated using a regulated speed motor; Rotation is sinusoidal. That is, the change in torque and angle displacement is a sine function with respect to time. This angle displacement corresponds to the shear distortion mentioned above; The torque of the regulated speed motor (which produces an angular displacement) corresponds to the regulated shear stress mentioned above; The gel has a density of greater than l, preferably greater than 1.1; The gel has less than 75, preferably less than 25 spontaneity (as described below).

자발성은 하기의 방법에 준하여 평가된다 :Spontaneity is evaluated according to the following method:

l50㎖들이 유리관(직경 22㎜)에 겔 1㎖와 물 99㎖의 혼합물을 넣고, 마개로 막아 실온에서 180°로 (거꾸로)뒤집는다. 겔을 완전히 분산시키는데 요구되는 횟수를 자발성이라 칭한다.A mixture of 1 ml of gel and 99 ml of water is placed in a 50 ml glass tube (22 mm diameter), capped and inverted (inverted) at room temperature 180 °. The number of times required to disperse the gel completely is called spontaneity.

"연속적 시스템"이라 함은 시각적으로 균질한, 즉 하나만의 물리적 상을 갖는 외관을 갖는 물질을 의미한다. 이는 물리적 상의 가시적 분리를 일으키지 못하도록 작기만하면, 작은 고체 입자가 거기에 분산되어 있을 가능성도 배제하지 않는다.By "continuous system" is meant a material that is visually homogeneous, ie has an appearance with only one physical phase. It does not exclude the possibility that small solid particles are dispersed therein, as long as it is small so as not to cause visible separation of the physical phase.

겔은 일반적으로, 분산된 상이 연속상과 조합되어 점성의 젤리 같은 생성물을 형성하는 콜로이드로 알려져 있다. 또한 이는 전형적으로 고분자량 화합물, 또는 액체와 매우 밀접하게 결합되어 있는 소립자의 응집물로 구성된 분산제이다.Gels are generally known as colloids in which the dispersed phase is combined with the continuous phase to form a viscous jelly-like product. It is also typically a dispersant composed of a high molecular weight compound, or agglomerates of small particles that are very tightly bound to the liquid.

주머니를 만들기 위해, 필름을 성형(부분적으로 봉하는 것도 가능)한 다음 겔로 충전시킬 것이 요구된다. 일반적으로 겔은 높은 점도로 인하여 속도가 느리긴 하지만 유동이 가능하다. 겔을 담기 위해 사용되는 용기는 이러한 높은 겔 점도 때문에 쉽게 비울수가 없다(이것이 현재까지 겔이 농약용으로 사용될 수 없었던 이유이다). 충전시에, 주머니를 마지막으로 봉하여(일반적으로는 열봉합하여) 밀봉한다.To make a pouch, the film is required to be molded (possibly partially sealed) and then filled with a gel. In general, gels are slow due to their high viscosity but are capable of flow. The container used to contain the gel cannot be easily emptied because of this high gel viscosity (this is why the gel could not be used for pesticides to date). Upon filling, the bag is finally sealed (usually heat sealed).

하기 실시예는 설명을 위해 주어지는 것이며, 본 발명의 범위를 제한하는 것으로 여겨서는 아니된다.The following examples are given for illustrative purposes and should not be taken as limiting the scope of the invention.
