Abstract
Abstract The present invention relates to a containerization system comprising at least one inner water soluble bag located within an outer water insoluble bag. The inner water soluble bag contains an agrichemical that does not substantially dissolve the bag. The outer water insoluble bag is flexible and collapsible and has a low stretchability; it may be made of polyester or laminated polypropylene-polethylene

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
95 words
A containerization system which comprises at least one inner cold water soluble bag containing an agrochemical composition in an outer water insoluble bag made of a flexible and sealed polymeric film, each bag having a surface area delimitated by the external largest outline thereof, wherein the surface area of the inner bag is at least 5% less than the surface area of the outer bag, and wherein the entire outer surface of said inner bag is loosely enclosed by the outer bag such that the inner bag is free to move in the outer bag.
Claim 2
Dependent Claim
95 words
A containerization system which comprises at least one inner cold water soluble bag containing an agrochemical composition in an outer water insoluble bag made of a flexible and sealed polymeric film, each bag having a surface area delimitated by the external largest outline thereof, wherein the surface area of the inner bag is at least 5% less than the surface area of the outer bag, and wherein the entire outer surface of said inner bag is loosely enclosed by the outer bag such that the inner bag is free to move in the outer bag.
Claim 3
Dependent Claim
21 words
A containerization system according to claim 1 wherein the outer bag is insoluble in the composition contained in the inner bag.
Claim 4
Dependent Claim
28 words
A containerization system according to claim 1, wherein the polymeric film of the outer bag of the containerization system has an elongation at break of less than 100%.
Claim 5
Dependent Claim
18 words
A containerization system according to anyone of claims 1, 2 or 3, wherein the polymeric film is collapsible.
Claim 6
Dependent Claim
19 words
A containerization system according to any one of claims 1, 2 or 3, wherein the agrichemical composition is solid.
Claim 7
Dependent Claim
19 words
A containerization system according to any one of claims 1, 2 or 3, wherein the agrichemical composition is fluid.
Claim 8
Dependent Claim
23 words
A containerization system according to any one of claims 1, 2 or 3, wherein the agrichemical composition is a liquid or a gel.
Claim 9
Dependent Claim
25 words
A containerization system according to any one of claims 1, 2 or 3, wherein the agrichemical composition is a powder or a dust or granules.
Claim 10
Dependent Claim
25 words
A containerization system according to any one of claims 1, 2 or 3, wherein the polymeric film has an elongation at rupture less than 30%.
Claim 11
Dependent Claim
20 words
A containerization system according to anyone of claims 1, 2 or 3, wherein the polymeric film is made of polyester.
Claim 12
Dependent Claim
24 words
A containerization system according to anyone of claims 1, 2 or 3, wherein the polymeric film has a thickness of 20 to 500 microns.
Claim 13
Dependent Claim
22 words
A containerization system according to claims 1, 2 or 3, wherein the polymeric film has a thickness of 30 to 100 microns.
Claim 14
Dependent Claim
66 words
A containerization system according to any one of claims 1, 2 or 3, wherein the agrichemical is selected in the group comprising plant protection agents, pesticides, insecticides, fungicides, herbicides, acaricides, nematicides, plant growth regulators, plant nutrients, or an adjuvant for the activity for plants as activity promoters including penetrating agents, synergists, antidotes, sticking agents, spreaders, activators, compatibility agents; adjuvants for the water soluble bags as plasticizers.
Claim 15
Dependent Claim
30 words
A containerization system according to any one of claims 1, 2 or 3, wherein the water soluble polymeric film constituting the inner bag comprises polyethylene oxide or methylcellulose, or polyvinylalcohol.
