Definitions

  • WATER SOLUBLE PACKAGE This invention relates to a water soluble or water dispersible package containing separate components of a final composition, and to a process for producing such a package.
  • Pesticides e.g. herbicides
  • Such chemicals are typically supplied in a metal or blow-moulded plastics container.
  • 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, and a method for producing the package, which contains a toxic, or most preferably 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; 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; and the chemical is in two component form with the two separate components both stored so as to be released for mixture and contact with water when activation is required.
  • At least one of the packaged components is toxic.
  • the toxic component is an agrochemical, preferably a pesticidal composition or plant growth regulator, most preferably it is the pesticidal composition.
  • FIG. 1 illustrates a first embodiment of the present invention.
  • FIG. 2 illustrates a second embodiment of the present invention.
  • the present invention provides a package containing a toxic composition
  • a package containing a toxic composition
  • package comprises a first sheet of non-planar water soluble or water dispersible material, 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 heat seal along a substantially planar continuous region of the superposed sheets, and a third sheet between the first and second sheets and joined to them along the continuous closed water soluble or water dispersible heat seal, whereby the third sheet divides the package into two sealed compartments which open on exposure of the package to water.
  • the invention further provides a process for producing 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 a toxic composition, the recess being bounded by a substantially planar flange; placing at least one component of a multi-component composition in the at least one recess; placing a second sheet on the flange and across every recess; placing a third sheet of water soluble or water dispersible material over said second sheet to enclose therewith at •least one further component of said multi- component composition; and heat sealing the first, second and third sheets along the flange to form a continuous water soluble or water dispersible heat seal.
  • the composition is preferably a pesticidal composition, more preferably in the form of two components which are to be stored apart and mixed only when the composition is to be activated for use.
  • 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 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 0.1 to 3 litres; from 0.5 to 5 litres is also a useful range.
  • the package will contain at least a small amount of space, e.g.”at least about 5% by volume, so as to minimise the likelihood of spillage of the composition during the production of the package.
  • SUBSTITUTE SHEET typically the two sheets of water soluble or water dispersible material are of the same material, but they may be different.
  • the water soluble or water dispersible material When 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 be a partially or fully alcoholised or hydrolysed, e.g.40-99%, preferably 70-92% alcoholised or hydrolysed, polyvinyl acetate 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. It 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 the envelope is preferably at least 20, more preferably from 30 to 80, N/mm 2 and the elongation at break is preferably 200 to 380%, more preferably from 220 to 350%. 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 layer of material.
  • the laminates will consist of 2 layers of thickness from 20 ⁇ m to 1mm, preferably about 40 ⁇ m, 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 ⁇ m, 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 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 invention is not limited to some specific pesticides (such as insecticides, fungicides, herbicides, acaricides or nemtocides; or plant growth regulators or plant nutrients) ; a list of the pesticides which can be used in the package of the invention includes: fungicides such as triadimefon, tebuconazole, prochloraz, triforine, tridemorph, propiconazole, pirimicarb, iprodione, metalaxyl, bitertanol, iprobenfos, flusilazol, fosetyl, propyzamide, chlorothalonil, dichlone, mancozeb, anthraquinone, maneb, vinclozolin, fenarimol, bendiocarb, captafol, benalaxyl, thiram; herbicides (or defoliants) such as quizalofop and its derivatives, acetochlor, meto
  • suitable organic solvents which may be used as carriers in the pesticidal composition include petroleum based solvents, e.g. petroleum ethers, mineral oils, aliphatic or aromatic hydrocarbons, e.g. hexane, octane, cyclohexane, benzene, xylene and naphthalene, halogenated aliphatic or aromatic hydrocarbons, e.g. carbon tetrachloride, chloroform, methylene chloride and chlorobenzene, esters, e.g. amyl acetate, ketones, e.g.

  • cyclohexanone, ethers, or a higher alcohol lower alcohols may migrate through the water soluble or water dispersible materials described above: this can result in product appearing on the outside of the envelope.
  • mixtures of solvents e.g. mixtures of a hydrocarbon solvent with another solvent such,as a ketone or a higher alcohol, may also be used.
  • the organic liquid must be reasonably dry and typically contains less than 2 to 3% of water by weight of the composition to ensure that it does not leak prematurely from the package.
  • compositions may comprise, in addition to, or in some cases instead of, an organic solvent as a carrier or diluent, a surfactant, which is reasonably dry in that it contains less than 2 to 3% water-
  • a surfactant may be of the ionic or non—ionic types: for example sulphoricinoleates, quaternary ammonium derivatives, products based on condensates of ethylene oxide with alkyl and polyaryl phenols, e.g.
  • the pesticidal composition may comprise up to 10%, e.g.
  • the contents of the package may be thickened or rendered thixotropic to provide a gel. An increased viscosity in the contents can reduce the likelihood of rupture if the package is subjected to mechanical shock.
  • the contents of the package may be rendered more viscous or thixotropic by the inclusion of additives, for example, a modified organophile, or bentonite, lecithin, polymethylene oxide or silica gel.
  • Gels which are of particular interest in the invention are organic gels which have viscosities of 600 to 30,000 centipoise, preferably 1,000 to 12,000 centipoise, and still more preferably 1,000 to 5,000 centipoise.
  • the material or gel which is used in the invention is essentially a material which has a phase difference phi between the controlled shear stress and the resulting shear strain, such that tg(phi) is less than or equal to 1.5, preferably less than or equal to 1.2, Tg(phi) is the tangent of the phi angle (or phase difference) .
  • the measurement of phi is made by means of a rheometer having a flat fixed plate and a rotating cone above this plate such that the angle between them is less than 10°, preferably less than 4°.
  • the cone is caused to rotate by means of a controlled speed motor; the rotation is a sinusoidal one, i.e. the torque and the angular displacement change as a sine function with time.
  • This angular displacement corresponds to the hereabove mentioned shear strain; the torque of the controlled speed motor (which causes the angular displacement) corresponds to the hereabove mentioned controlled shear stress.
  • a gel is generally a colloid in which the dispersed phase has combined with the continuous phase to produce a viscous, jelly-like product; it is also a dispersed system consisting typically of a high molecular weight compound or aggregate of small particles in very close association with a liquid.
  • the gels used in the invention have basically an organic continuous phase.
  • most of the existing materials/gels are water based and have an aqueous continuous phase.
  • the gels used in the invention have essentially one physical phase, at least as can be seen when visually observed.
  • Preferred gels in the invention are also gels which can be divided by cutting and whose cut parts are able to merge together by simple juxtaposition.
  • concentrations of pesticide or herbicide dissolved or dispersed in the organic liquid or in the gel will generally be those conventionally used: in order to reduce the bulk of each package, however, concentrations may be increased.
  • Each package will preferably contain at least about 100 ml andwill preferably contain a convenient standard volume, for example 500 ml or 1 litre, although it will be appreciated that any convenient standard volume may be chosen.
  • thepesticidal composition when in solid form then it may comprise-any conventional carrier or diluent which is reasonably dry, in that it contains less than 5 to 10%, e.g. 2 to 3% of moisture.
  • suitable solid diluents or carriers are aluminium silicate, talc, calcined magnesia, kieselguhr, tricalcium phosphate, powdered cork, adsorbent carbon black and clays such as kaolin and bentonite.
  • Solid compositions may comprise surfactants, such as dispersing agents, for example those surfactants previously mentioned. In some cases such surfactants may also be used as diluents or carriers.
  • the concentration of pesticide in the solid pesticidal compositions may be as conventionally used: concentrations may however be increased to reduce the bulk of the package.
  • the pesticidal compositions used in the package of the present invention may be prepared by conventional means.
  • the packages of the present invention may be inside an additional outer container.
  • a container may " provide additional strength and if water resistant may serve to protect the package of the present invention from accidental exposure to water.
  • the outer container is preferably sealed to avoid exposing the package of the present invention to undue moisture.
  • the package of the present invention comprises more than one compartment which may contain the same toxic compositions or components of a multi-component composition.
  • SUBSTITUTE SHEET are particularly useful where a combination of components are to be employed together and where the components are incompatible for a prolonged period, for instance if they react chemically.
  • Two or more different toxic compositions may be present in the package.
  • One or more of the compositions in a multicompartment package may comprise a component, such as a surface active agent which is incompatible with the toxic composition or which it is simply desired to package separately.
  • the dividing sheet which separates the two compartments of the package itself be formed of water soluble or water dispersible material
  • any other material compatible (as regards heat sealing) with that used for each of the outer sheets can be used because removal of the two outer sheets by dispersion or dissolution will release the two components of the composition for dilution in the surrounding mass of water and for reaction when they come into contact with one another.
  • the fact that the dividing sheet may still be present in the thus-constituted pesticidal composition will be no great disadvantage provided this does not lead to disturbance of mechanical handling operations such as spraying of the composition (for example by the sheet blocking.the spray holes). Where the dividing sheet itself dissolves or disperses, the best possible results are obtained.
  • the structure of the package may in one example comprise a single thermoformed tray having a first component of the pesticidal composition placed on the floor of the tray and then covered by a dividing sheet which ultimately becomes sealed to the flanges of the thermoformed tray by sealing, and then the completion of the package would comprise placing a second component on the dividing sheet and subsequently covering that second component with a further water soluble or water dispersible sheet which thus encloses a second component and closes the package as a whole.
  • a further possibility involves the formation of two flanged trays, by thermoforming or vacuum " forming, of water soluble or water dispersible sheet material and then filling the first tray with at least one first component, covering that tray with the dividing sheet and sealing the covering sheet to the flanges of the tray to enclose said at least one first component, then placing at least one further component in the second thermoformed tray and covering it with the already completed first thermoformed tray, its contents and dividing sheet whereby the cover sheet for the first tray then forms the dividing sheet between the first and second trays; the sealing of the package is completed by sealing the dividing sheet material which covers the flanges of the first tray to the flanges of the second tray, by a water soluble or water dispersible seal.
  • the package may comprise loosely formed pouches which include a third sheet in the structure to divide a first compartment from a second compartment, where the third sheet is optionally water soluble or water dispersible and is in any case sealed to the perimeters of the two outside sheets, with the various components of the herbicidal composition in the package to either side of the third sheet.
  • a package may be formed by leaving the heat seal open along one edge of the package so as to allow access of a filling nozzle into the package alternately to each side of the dividing sheet, and then completing the seal to close the two compartments and to form a continuous water soluble seal around the dividing sheet.
  • the degree of filling of the pouches will maintain two limp water soluble or water dispersible outer sheets in a non- planar configuration.
  • a multi-component pesticidal composition may be stored in more than two compartments if additional dividing sheets are provided, with a component of the composition sandwiched between two of the dividing sheets of such a package.

  • the packages of the present invention may be obtained' by first deforming a sheet of water soluble or dispersible material so as to form a recess adapted to retain a pesticidal composition. This may be achieved for example by a vacuum forming where the sheet is deformed to conform to the shape of a suitable mould and may, if desired, be a thermoforming process to cause the sheet to retain its shape after release from the mould. Where the deformation is by vacuum forming, the mould may be equipped with perforations through which the space between the mould and the sheet can be evacuated.
