Abstract
A package containing an agrochemical composition which package comprises a first sheet of non-planar water soluble or water dispersible material defining a concavity enclosing the agrochemical composition and a second sheet of water soluble or water dispersible material sealed to the first sheet by a continuous closed water soluble or water dispersible seal.
Description
The present invention relates to a kind of agricultural chemicals, for example a kind of water-soluble or water dispersible packing of composition pesticide, and the method for making this packing of being equipped with.
The agricultural chemicals that comprises agricultural chemicals, herbicide for example, they often are the materials that the poison of diving is arranged, and product often is coned sol or dispersion suspension liquid in the organic liquid, or exist with gel or solid form.This chemical by regular be to place metal or blow-moulding plastic containers.Using chemical pesticide, for example herbicide, before being sprayed onto on a need processing region or the plant, is that agricultural chemicals (the being in enrichment stage) weighing from container of some is taken out, mixed with a large amount of water then.This condensed matter often is a high toxicity, so that must extreme care when mixed with water, avoids spilling, and avoids human body or animal and should contact by concentrated agricultural chemicals.
People once were devoted to design containers, the danger of their the little accidental release of medicament of containing during use, and remain in after using in the container residuum also seldom.The plastic container wide-mouth is so that topple over out with its agricultural chemicals of containing.Developed the blow-moulding plastic containers with hollow handle, this hollow handle and vessel separate, to avoid that residues of pesticides are arranged in handle.
But, current is packaged in the mixed process, because of leakage easily produces the dangerous of the pollution of environment and the danger that human body or animal are contacted.And peasant and other user seldom use up the agricultural chemicals in the container, so tend to stay the container that part is filled.This just has further harmfulness.Even use up when all medicaments, also be difficult to handle empty receptacle, also be difficult to abundant clean container and handle the utensil of measuring that concentrates agricultural chemicals.And these utensils can further have harm to human body and environment.
Once proposed agricultural chemicals is encapsulated in the container with screw thread, this screw thread matches with respective threaded on being contained in spray jar.Have only when having gratifying sealing between spray jar and the container, the content in the container just can be emitted.Because the needs that the standard thread size cooperates, and, if poor sealing can produce leakage, so the system that this agricultural chemicals of widespread use encapsulates and applies still has practical difficulty.
And also proposed chemical is encapsulated in the water-soluble container, this container only with the chemical that just discharges packaging after water contacts.Yet this application mode often is splintery and restricted because of the water-soluble container known to so far.To avoid simultaneously producing aperture (it can cause the seepage of content) at container heat-sealing knot place, and the bad reduction that will avoid near container material heat-sealing knot place, all be difficult.
DE1,287,502 and WO 89/12587 packing of a kind of product in the water-soluble polymer films foreskin also disclosed.DE1,287,502 relate to having and are used for forming the molding drum of mould depression of shrinkage pool and the package packing machine that the coverlay that will be clamminess is pressed in the pressure roller on the product that article are housed by the vacuum draw film.WO 87/12587 discloses a kind of with the packing of liquid containing in water-soluble or water-dispersible material foreskin.
The present invention tries hard to overcome the shortcoming of existing known package, and a kind of packing of adorning agricultural chemicals, for example composition pesticide and having following one or more advantage feature is provided:
Packaged chemical only with just discharge (packing are dissolved or dispersion suspension therein) after water contacts, thereby undiluted material and environment or the possibility that contacts with the accident of human body or animal are reduced to minimum;
This chemical can provide by the unit batching, is suitable for diluting with the water of predetermined quantity, and need not undiluted chemical weighing is taken out.
Packaged chemical is easy to use: when using it as long as be placed in the water simply;
Need not in container, to clean residual chemicals,, be convenient to dispose because the container that contacts with the chemical substance of packaging still keeps not stain so that carry out its safe disposal.
We have designed a kind of novel package soluble in water now, and this packing is cheap, it is simple to make, and its intensity is unexpected big, and bend resistance and breaking.
The invention provides a kind of agricultural chemicals that is equipped with, the packaging body of composition pesticide for example, this packing comprises the ground floor of non-planar water-soluble or water-dispersible material, be stacked in the second layer of the water-soluble or water-dispersible material on the described ground floor, the described second layer along stacked double-ply continuum together by the water-soluble or water dispersible heat seal of single continuous fully enclosed and ground floor sealed knot, wherein the ground floor and the second layer all are a lamination that has two-layer water-soluble or water-dispersible material at least separately.Stacked double-ply continuum is preferably the plane substantially.
The present invention further provides a kind of manufacturing the method for the packing of agricultural chemicals is housed, described packing comprises the ground floor of non-planar water-soluble or water-dispersible material, be stacked in the second layer of the water-soluble or water-dispersible material on the described ground floor, the described second layer along stacked double-ply continuum by the water-soluble or water dispersible heat seal of single continuous fully enclosed and ground floor sealed knot together.Described method comprises:
At first, water-soluble or aqueous suspension material are suppressed ground floor, it is a non-planar shaped, and it has for example recess of composition pesticide of agricultural chemicals that is fit to pack at least, and described recess is surrounded by a flange, and this flange is the plane better substantially.
With a kind of agricultural chemicals, for example composition pesticide is packed at least one recess.
The second layer of water-soluble or water-dispersible material is crossed this recess or each recess, be placed on the flange;
Along flange heat-sealing knot ground floor and the second layer, to form a water-soluble or water dispersible sealing of continuous fully enclosed.
This agricultural chemicals can be, for example, and plant protection product, plant growth regulator or plant nutrient chemical.A kind of example of plant protection product is agricultural chemicals (for example a kind of insecticide, bactericidal agent, herbicide, acaricide or a nematicide).
Composition pesticide can be to exist with liquid phase or solid phase or gel form.It can comprise carrier or the diluent or the inhibiter of any routine.When composite is a liquid phase, it can be solution or dispersion liquid (for example emulsion or suspending fluid) in a kind of organic liquid.Similarly, if the composite gel, the agricultural chemicals in the said composition can be or be dissolved in or be scattered in the medium of this dryness substantially.
Packing of the present invention, if the composite solid phase that it is adorned, then generally can adorn and restrain 7 kilograms from 0.1, be preferably 1 kilogram to 5 kilograms, when composite is to exist with liquid phase or gel form, this packing generally can be held 1 milliliter to 10 liters, is preferably from 0.5 to 5 liter (preferably 0.1 being raised to 1.5 liters); More small-sized can be from 5 milliliters to 1 liter.
General this packing leaves a little space at least, for example presses volumometer at least about 5%, so as during packing manufacturing, said composition can be overflowed may reduce to minimum.
Especially the content when packing is a solid, when for example be pulvis or granula, the manufacturing of this packing make wherein be find time or content next at decompression state be useful.The packing of Zhi Zaoing has many advantages like this, has for example increased the resistivity of impact to a great extent.The pulvis of this packing or granula be in compaction state and be film skin packaging effectively.The compaction state of content just makes this packing if fall into the water and can sink, and this occupies less space when being packaged in storage.Therefore, the advantage of this packing comprises under decompression state:
A) because not existing of the gas around the agrochemical compositions just reduced for example damaged at low temperatures possibility of this packing.Generally at low temperatures, for example near 0 ℃, constitute the water-soluble plastic thin film of packing, polyvinyl alcohol for example can become fragile and makes this packing than cracky.Reduce the space in the packing that agrochemical compositions is housed, just reduced the possibility of composite pulvis or granula motion, also just reduced the possibility of breakage of packages.
B) when agrochemical compositions exists with the granula shape, when this packing was close packing, particle was fragmented into may reducing of fine powder (may causing for example decomposition of active component).
C) Bao Zhuan density can change consciously because of the decompression degree of packing.This will further provide advantage, for example, makes and can sink when packing is inserted in the spray jar and improve the dissolution velocity of this packing.
D) when agricultural chemicals is a kind of granular solids that does not add adhesives, for example plasticizer, then the package interior decompression can keep agricultural chemicals be substantially rigid unitary, help preventing the size separation of agricultural chemicals and possible decomposition.(this agricultural chemicals may can not be compatible with some plasticizer: add in the agricultural chemicals plasticizer also may with film can not be compatible).
Two-layer water-soluble or water-dispersible material generally is a same material, but their may be different.Water-soluble or the water-dispersible material of one deck can be easy to print up.
When composition pesticide is to exist with liquid phase or gel, and when containing a kind of organic solvent, water-soluble or water dispersible packing should be insoluble to organic solvent.
Suitable water-soluble or water-dispersible material is polyethylene oxide and methylcellulose.What better use is a kind of polyvinyl alcohol (PVOH) film.This PVOH film can be partly or entirely alcoholization or aquation (for example 40-90% is a 70-92% alcoholization or aquation preferably) polyvinylacetate film.This film can be a kind of made membrane that waters, preferably a kind of blown film or extrusion forming film.
This polyvinyl alcohol film can be nondirectional, uniaxial orientation or biaxial orientation.Preferably use water-soluble material, because its handling problems is little.Used material generally is soluble in cold water; Be preferably the polyvinyl alcohol of cold water solubles.Need to understand, when this packing is to prepare in cold water or in the hot water dissolving or when disperseing, also can use other material.Water-soluble or water-dispersible material generally is pliable and tough.
The ultimate tensile strength of encapsulating material is 20 at least preferably, and best is from 30 to 80 Ns/millimeter
2, and can be up to 200 Ns/millimeter
2Or it is more; The degree of drawing that breaks preferably is 200 to 380%, and best is from 220 to 350%, and can be up to 500% or more.Generally test these data 23 ℃ and 50% relative humidity.
When agrochemical compositions was liquid phase or gel form, in packing, should avoid making the aperture of composite generation seepage was particular importance.Thereby water-soluble or water-dispersible material is with a lamination, and it generally is made up of different (or better by identical) two-layer water-soluble or water-dispersible material, because vesicle unlikely is superimposed together in two layers of material.This lamination respectively is from 20 microns to 1 millimeter by 2 layer thicknesses generally, and two layers that are preferably 40 microns constitute.Yet generally the thickness of these layers should remain on the minimum that stops breakage of packages to need, and the while can make the layer material of water-soluble or water dispersible dissolve as soon as possible again or disperse, and discharges agricultural chemicals then.
When agrochemical compositions exists with solid phase, especially need avoid on the packing aperture with the situation that for example stops undesirable smell and overflow under, can use the lamination of top described type.The same with the situation of packing liquid and gel, for the packing of dress solid composite, the thickness of water-soluble dispersed material generally also remains on its minimum value.
When packing is preferably when being made by method for hot forming, the thickness of ground floor generally is not less than 20 μ, and (for the convenience that keeps making) generally is no more than 1 millimeter.Scope is from 80-400 μ preferably, 100-400 μ for example, and that best is about 250 μ.
Because of the second layer is not thermoforming generally, the local reduction of bed thickness can not take place, so the thickness of the second layer can be littler than ground floor when promptly being shaped.The thickness of the second layer generally is not less than 10 μ m and is preferably and is not less than 20 μ m.And for the ease of processing and fabricating, film generally is no more than 1 millimeters thick, one preferably scope be best from 20 μ m to 250 μ m be about 150 μ m.
In a special embodiment, the packing that is provided has a zone, and it can be dissolved in water more quickly than the remainder of this packing.The advantage of this generation is for example to quicken the dispersion of contained agricultural chemicals in packing.The way that reaches this purpose can be for example to form one deck than the thin water-soluble or water-dispersible material of other layer or by making the part of these packing thinner than remainder.
On packing of the present invention, not along the seam of packing a center of surface.This demonstrates preceence than those known packings, for example when packing is subjected to impacting, the possibility that fracture takes place in the body is just lower, must have one two or many points that seam intersects because have along the packing of the seam of a center of surface, and this under the situation of being hit than the same packing that does not have this joining easy fracture more.
The two-layer water-soluble or water-dispersible material layer of this packing then is enclosed in together by closely continuous heat-sealing knot.Should guarantee that generally sealed knot is water miscible and leakage can not be arranged, sealed knot should be single continuous, and does not have the discountinuity on how much, also is that it self does not have intersecting of angle.Thereby heat-sealing knot generally is curved, at least on part so, on the angle of packing, be curved for example.The radius of heat-sealing knot camber line generally is not less than 1 millimeter, is preferably and is not less than 5 millimeters, but be no more than package-width half.
