  • Copolymers or other derivatives of such polymers can also be used.
  • Additional preferred materials for constituting the bags in the invention are polyethylene oxide, methylcellulose, and polyvinylalcohol.
  • a hazardous chemical can be any compound which can easily cause extreme injury to persons exposed to the chemical or which can easily damage the environment. Examples are acids, bases, caustics, poisons, and agrochemicals.
  • An agricultural chemicals or agrochemicals are compounds such as pesticides (e.g., herbicides, fungicides, nematocides, insecticides, etc.) and plant protection agents (e.g., plant growth regulators, nutrients, etc.).
  • Agrochemicals also include plant adjuvants such as penetrating agents and the like.
  • Hazardous chemicals or agricultural chemicals may be in any convenient form, for example, solid, liquid, or gel and are preferably water soluble or dispersible. Liquids and gels are preferred with gels being especially preferred.
  • a gel is generally a colloid in which the dispersed phase has combined with the continuous phase to produce a viscous, jelly-like product.
  • a gel can be 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 usually have an organic continuous phase. Furthermore, the gels used in the invention have essentially one physical phase, at least as can be seen when visually observed. Gels that are preferred for the invention are those which can be divided by cutting and whose cut parts are able to merge together by simple juxtaposition.
  • Solvents useful in the gel of the present invention are organic solvents such as petroleum hydrocarbons which include aliphatic and aromatic solvents.
  • Surfactants that can be used in the invention are nonionic and anionic surfactants and combinations thereof.
  • Illustrative gelling agents that can be used include mixtures of dioctyl sulfosuccinate salt and sodium benzoate, tetramethyl decynediol ethyoxylated dialkylphenol, combinations of modified clay and propylene carbonate, hydrogenated castor oil, ethoxylated vegetable oil, dioctyl ester of sodium succinic acid and sodium benzoate, diatomaceous earth, and mixtures of dimethyl hexane and hexyne diol.
  • the gel material which is used in the invention is essentially a material which has a phase difference L between the controlled shear stress and the resulting shear strain such that tgL is less than or equal to 1.5, preferably less than or equal to 1.2.
  • TgL is the tangent of the L angle (or phase difference).
  • the measurement of L is made by means of a rheometer having a flat fixed plate and a rotating cone above this plate such as the angle between them is less than 10°, preferably 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.
  • the gel which may be used in the invention is primarily organic, which means that it has a low water content, generally less then 5% (by weight), preferably less then 3%, more preferably less than 1%.
  • the gel which may be used in the invention is a material having a viscosity from 500 centipoise (measurement made with a Brookfield viscometer at 23°C, with a flat plate rotating at 20 round per minute) to 50,000 centipoise, preferably between 1,000 and 30,000 centipoise, and still more preferably between 1,000 and 5,000 centipoise.
  • the gels which are used in the invention are successful when submitted to the following puncture test: 500 g of a material/gel are placed in a polyvinyl alcohol water soluble bag (having a 50 micron thick wall) and heat sealed. The bag is suspended using a binder clip at which time a dissecting needle (the diameter of which is 0.1 mm) is inserted into the lower third of the bag and withdrawn. The material/gel is observed for 30 minutes to determine leakage.
  • a gel which is successful in the present test shows no leakage and preferably may be used in the invention. A droplet of material may appear on the hole, but no persistent flowing or leaking occurs.
  • the viscosity should be generally between 500 and 50,000 centipoise, preferably between 1,000 and 30,000 centipoise, and still more preferably between 1,000 and 5,000 centipoise (measurement made with a Brookfield machine).
  • the dispersibility in water should be substantially complete when the gel is subjected to normal agitation in water after a 15-minute interval, preferably after a 10-minute interval.
  • the gel preferably contains an essentially nonaqueous solvent.
  • the gels and the bag containing gel of the invention preferably have a density greater than 1, preferably greater than 1.1.
  • the Hazardous chemical used in the invention and is contained in the water soluble bag comprises the active ingredient, which is the hazardous chemical in association with ingredients that participate in or assist in the formation of the gel, for example, surfactants, dispersants, thickeners, solvents and gelled or gelling agents.
  • the bag also be enclosed in an additional non-water soluble flexible bag. In the event of severe trauma which does break the bag the outer bag will help contain any leak.
  • rigid containers herein is meant those rigid containers normally used to ship product such as water soluble bags. These are normally made of corrugated board but can be made of plastic, metal, wood, or any other similar rigid material approved for use in the shipping trade.
  • the bag length perimeter is the measurement taken when a bag is placed on a flat level surface measuring entirely around the length of the bag both top and bottom.
  • Figure 3 is a representative of a bag on a length view with the arrows indicating the perimetal length measurement.
  • the bag width perimeter is the measurement taken when a bag is placed on a flat level surface measuring around the width of both top and bottom.
  • Figure 4 is a representative of a bag width perimeter with arrows indicating the perimeter width measurement.
  • the "inside perimeter” is measured by using the inside measurements of the sides of the box in contact with the respective width and length of the bag.
  • 1 is a width
  • 3 is height.
  • the perimeter corresponding to bag(s) length perimeter would be 2 x (length + width) while the determination for the box dimensions in contact with the width would be 2x(Width + Height).
  • the bag perimeter might be width 2.25 height 3.75 for a box perimeter of 2(2.25 + 3.75) or a perimeter of 12, the bag should have no more width perimeter than about 12.
  • the length perimeter is measured by using the inside measurements of the sides of the box in contact with the respective width and length of the bag.
  • a plurality of bags can be placed in a box of the invention.
  • a divider may be placed between the 2 or the wall of one bag may form a wall of the inner perimeter of the rigid container for purposes of this invention. While that wall may not be as rigid as say corrugated board, it appears that the inner wall such as this can be used without detracting from the effectiveness of the invention.
  • dotted line 4 becomes a wall of both the first bag and second bag therein. Since the bags are flexible it is possible to fit bags with 2 dimensions bigger than the inner dimensions of the box with the contents of the bag shifting accordingly. Of course there is a physical limit to the difference which will become readily apparent to those skilled in the art upon applicating the invention containerization system.
  • Bags containing Buctril brand gel made according to U.S. Patent 5,080,226. They were enclosed in water soluble polyvinyl alcohol bags sealed and further placed in water insoluble outerwraps of a polyethylene type film. The films are wrapped tight around the bag.
