Abstract
This invention relates to a containerization system and to containers which are particularly suitable for storing, packaging and transporting toxic or hazardous products, such as agricultural chemicals. The containerization system comprises the chemical in the form of a gel which is contained within a water-soluble or water-dispersible bag.
Claims75
A containerization system for holding and securing agricultural chemical compounds which comprises a water soluble or water dispersible bag which completely encloses a gel, said gel comprising an agricultural chemical compound, wherein said gel possesses non-flowability characteristics to substantially prevent persistent flow or leakage of the agricultural chemical compound from the bag in the event the bag develops pinholes.
A self-dispensing containerization system for agricultural chemical compounds that are used in aqueous compositions, said system comprising a water-soluble or water-dispersible bag which encloses a gel of substantially organic material comprising an active agricultural chemical compound and other gel ingredients wherein the gel has a viscosity of between about 1000 and 30,000 centipoise, the density of the bag with the gel contained therein is greater than 1 and the bag and gel are sufficiently water dispersible so that they are substantially completely dispersed in agitated water within 15 minutes.
A method for holding and securing agricultural chemical compounds in a manner to prevent their contact with the environment during shipment and storage, said method comprising:
- (i) mixing at an elevated temperature an agricultural chemical compound with other gel ingredients until the agricultural chemical compound and ingredients are sufficiently dissolved or dispersed to appear visually as a substantially single phase,
- (ii) allowing the mixture to cool and to form a gel, and
- (iii) enclosing and sealing a predetermined amount of said gel within a bag of a water-soluble or water-dispersible film.
A containerization system for holding and securing agricultural chemical compounds which comprises a water soluble or water dispersible bag which completely encloses a gel, said gel comprising an agricultural chemical compound, and said gel having a phase difference L between the controlled shear stress and the resulting shear strain such that tgL, the tangent of the L angle or phase difference, is less than or equal to 1.5.
A containerization system for holding and securing agricultural chemical compounds which comprises a water soluble or water dispersible bag which completely encloses a gel comprising an agricultural chemical compound, said gel having a viscosity of between about 1000 and 30,000 centipoise.
A containerization system for holding and securing agricultural chemical compounds which comprises a water soluble or water dispersible bag which completely encloses a gel comprising an agricultural chemical compound, said gel having a viscosity of between about 1000 and 5000 centipoise.
A method for holding and securing agricultural chemical compounds in a manner to prevent their contact with the environment during shipment and storage, said method comprising:
- (i) mixing at an elevated temperature an agricultural chemical compound with other gel ingredients until the agricultural chemical compound and ingredients are sufficiently dissolved or dispersed to appear visually as a substantially single phase,
- (ii) allowing the mixture to cool and to form a gel, said gel having a viscosity of between about 1000 and 50,000 centipoise,
- (iii) enclosing and sealing a predetermined amount of said gel within a bag of a water-soluble or water-dispersible film.
A containerization system for holding and securing agricultural chemical compounds which comprises a water soluble or water dispersible bag which completely encloses a gel, said gel comprising an agricultural chemical compound, and said gel having a viscosity above 500 centipoise and less than 50,000 centipoise.
The containerization system according to claim 77 wherein the gel has a spontaneity of less than 25.
