Definitions

  • This invention relates to a water soluble or water dispersible package containing an agrochemical, eg a pesticidal composition, and to a process for producing such a package.
  • Agrochemicals include pesticides, e.g. herbicides, which are often potentially harmful materials and are commonly produced as a concentrated solution or dispersion in an organic liquid, as a gel or in solid form. Such chemicals are typically supplied in a metal or blow-moulded plastics container.
  • chemical pesticides e.g. herbicides
  • a quantity of the pesticide is measured out of the container in concentrated form and then mixed with a large volume of water before being sprayed onto a locus to be treated or onto plants.
  • concentrated materials are frequently highly toxic so great care must be taken in measuring and mixing them to avoid spillage and to avoid human or animal contact with the concentrated pesticide.
  • the present invention seeks to overcome the disadvantages of known packages and to provide a package which contains an agrochemical such as a pesticidal composition and has one or more of the following advantageous features: the packaged chemical is released only after contact with water in which it is to be dissolved or dispersed, minimising the possibility of accidental contact of the undiluted material with the environment or with humans or animals; the chemical can be provided in unit dosage form suitable for dilution with a predetermined amount of water removing the need for undiluted chemical to be measured out; the packaged chemical is easy to use : the packaged chemical can be simply placed in water prior to use of the chemicals; and the need for washing out of the residual chemical from containers to render them safe for disposal is removed: containers which have been in contact with the packaged chemical remain uncontaminated which facilitates their disposal.
  • an agrochemical such as a pesticidal composition
  • the present invention provides a package containing an agrochemical, eg a pesticidal composition, which package comprises a first sheet of non- planar water soluble or water dispersible material and a second sheet of water soluble or water-dispersible material superposed on the first sheet and sealed to it by a continuous closed water soluble or water dispersible seal along a continuous region of the superposed sheets.
  • the seal may be produced using a solvent, eg water, or using eg ultrasound but is preferably a heat seal.
  • the continuous region of the superposed sheets is preferably substantially planar.
  • the invention further provides a process for producing such a package which comprises: moulding a first, sheet of water soluble or water dispersible material to form a non-planar sheet comprising at least one recess adapted to retain an agrochemical, eg a pesticidal composition, said recess being bounded by a flange, which flange is preferably substantially planar; placing an agrochemical, eg a pesticidal composition in the at least one recess; placing a second sheet of water soluble or water dispersible material on the flange and across the or every recess; and sealing (preferably heat sealing) the first and second sheets along the flange to form a continuous closed water soluble or water dispersible seal.
  • the agrochemical may be, for example, a plant protection agent, a plant growth regulator or a plant nutrient.
  • a plant protection agent is a pesticide (such as an insecticide, fungicide, herbicide, acaricide or nematocide) .
  • the pesticidal composition may be in liquid form, or solid form, or gel form. It may comprise any conventional carrier or diluent or surfactant. Where the composition is in liquid form it may be in the form of a solution or of a dispersion in an organic liquid, e.g. an emulsion or a suspension. Similarly in gel form, the composition may contain pesticide either dissolved or dispersed in the substantially f dry medium.
  • the packages of the present invention generally contain from 0.1 grams to 7kg, preferably lg to 5kg, where the composition is in solid form. Where the composition is in liquid or gel form, the package typically contains from 1ml to 10 litres, preferably from 0.5 to 5 litres (0.1 litres to 1.5 litres is especially preferred) ; on a smaller scale a range of 5ml to 1 litre is also useful.
  • the package will contain at least a small amount of space, eg at least about 5% by volume, so as to minimise the likelihood of spillage of the composition during the production of the package.
  • the package produced is evacuated of air or the contents are under reduced pressure.
  • the package thus produced has a number of advantages, for example substantially increased resistance to shock.
  • a powder or granules in such a package is compacted and is, effectively, skin-packaged within the film. Compaction of the product makes the package more likely to sink when dropped into water and the package occupies less space during storage.
  • the advantages of packaging under reduced pressure include: a) the absence of gas surrounding the agrochemical composition reduces the possibility of the package failing for example, at low temperatures.
  • the package may be advantageous for the package to hold the agrochemical substantially rigid within the package to prevent segregation and possible decomposition of the agrochemical (which may be incompatible with certain plasticisers: the plasticiser in the agrochemical may also be incompatible with the film) .
  • the two sheets of water soluble or water dispersible material are of the same material, but they may be different.
  • One sheet of the water soluble or water dispersible material may be easy to print upon.
  • the pesticidal composition is in liquid or gel form and comprises an organic solvent the water soluble or water dispersible material will be one which is insoluble in the organic solvent.
  • Suitable water soluble or dispersible materials are polyethylene oxide and methyl cellulose. More preferably a polyvinyl alcohol (PVOH) film is used. Such a PVOH film may a partially or fully alcoholised or hydrolysed e.g.40-99%, preferably 70-92% alcoholised or hydrolysed, polyvinyl acetate film. The film may be a cast film or, more preferably, a blo or extruded film.
  • PVOH polyvinyl alcohol
  • the polyvinyl alcohol film may be unoriented, mono axially oriented or bi-axially oriented.
  • Water soluble materials are preferred since they provide less disposal problems.
  • the materials used will generally be cold water soluble; cold water soluble polyvinyl alcohol is preferred. I will be understood that other materials may be used when the package is to be dissolved or dispersed in water or hot water. Generally the water soluble or water dispersible material will be flexible.
  • the maximum tensile strength of the material of th envelope is preferably at least 20, more preferably from 30 to 80, N/mm 2 and may be as much as 200N/mm 2 or more; and the elongation at break is preferably 200 to 380%, more preferably from 220 to 350% and may be as much as 500 per cent or more. Testing for these values is generally carried out at 23°c and 50% relative humidity.
  • the water soluble or water dispersible material will typically be a laminate, generally of two layers of different or preferably the same water soluble or water dispersible material, as pinholes are unlikely to coincide in two layers of material.
  • the laminates will consist of 2 layers of thickness from 20 ⁇ m to 1mm, preferably about 40 ⁇ rt, each. Generally however the thickness of the layers will be kept to the minimum needed to prevent rupture of the package, so that the water soluble or dispersible material is dissolved or dispersed as quickly as possible and the pesticide then released.
  • the sheets of water soluble or water dispersible material typically comprise a single layer of material.
  • the material will generally be from 20 to 500 ⁇ m, preferably 30 to lOO ⁇ , thick.
  • a laminate material of the type described above may be used.
  • the thickness of the water soluble dispersible material will generally be kept to a minimum in packages containing solid compositions.
  • the thickness of the first sheet will generally not be less than 20 ⁇ and (to maintain ease of processing) generally not more than 1 mm.
  • a preferred range is from 80-400 ⁇ , eg 100-400 , most preferably about 250 ⁇ .
  • the thickness of the second sheet may be less than that of the first sheet as the second sheet will not generally be thermoformed so that localised thinning of the sheet will not occur.
  • the thickness of the second sheet will generally not be less than lO ⁇ , preferably not less than 20 ⁇ .
  • the film will generally not be more than 1 mm thick, a preferred range being from 20 to 250 ⁇ , most preferably about 150 ⁇ .
  • the package is provided with a region which will more readily dissolve in water than the rest of the package.
  • This offers advantages, for example by speeding up the dispersion of the agrochemical contained in the package.
  • the region may be provided for example by making one sheet of the water-soluble or water dispersible material thinner than the other, or by making one portion of the package thinner than the rest.
  • the package does not possess a seam running down the centre of one of the faces of the package. This offers advantages over known packages, for example by reducing the likelihood of failure occurring in the package when it is subjected to shock, because packages having a seam running down the centre of one of the faces of the packages necessarily have a point at which two or more seals intersect which will be more likely to fail under shock than the equivalent package not having this point of intersection.
  • the two water soluble or water dispersible sheets in the packages are sealed together by a closed continuous heat seal.
  • the seal is water soluble and does not suffer from leakage, it is a single continuous seal and has no geometrical discontinuities, i.e. it does not comprise any angular intersections with itself. Therefore the heat seal will usually be curved, at least in portions, for instance at the corners of the package: the radius of curvature of the heat seal will generally not be less than 1mm, preferably not less than 5mm, and not more than half the width of the package.
  • Suitable pesticides which may be used in the package of the present invention include fungicides, insecticides and herbicides (for example hydroxybenzonitrile herbicides, e.g. bromoxynil or ioxynil or derivatives thereof such as salts or esters, e.g. heptanoates or octanoates) .
  • olluscicides suitable for addition to, for example, ponds or streams may also be employed.
