DETAILED DESCRIPTION OF THE INVENTION
The reclosable compartmentalized envelope of the present invention is generally illustrated by Figs. 1-10 The envelope Fig. 1, reference number 11, can be formed with one or more pieces of material 0 2~ ~922 1 Mo-4406 -3-by: folding and/or lapping and sealing the ends of the material to form the envelope. The material is sealed on the outside to forrrl the outside boundaries and on the inside to form the inside boundaries defining the compartments. The front end of the envelope is provided with a reclosable means by attaching it to lips on the front panel of the envelope. Generally, the material useful herein is sufficiently durable to remain intact during shipping, storage and use of the envelope. Further, the material must have sufficient moisture barrier to protect the pouches contained therein. Also, the material is such that it can be equipped with or adapted to have a means of reclosing the envelope. Typically, the material comprises a flexible film. Specific but non-limiting examples of the material can be selected from the group consisting of: polyethylene, polyester, polyamide, polypropylene, ethylene vinyl alcohol, aluminum foil and a mixture or composite thereof. The dimensions of the envelope depend on the type of material and the service conditions of the envelope. Illustratively, an envelope that is made of a polyolefin material would have outside dimensions of about 16 to 24 inches in length, 6 to 10 inches in height and 1 to 2 inches in thickness (expansion) when the envelope contains filled pouches.
The envelope is defined by its outside boundaries and inside boundaries that form two or more compartments as illustrated by reference numbers 12, 14, 16, and 18 which are separated from each other. The separation between the compartments can be provided by fastening the material of the front panel to the ",aterial of the back panel of the envelope, at desired inside boundaries 41, 43, and 45. Any effective fastening means, such as sealing, can be used to provide the separation. Preferably, the sealing can be done by heat-sealing.
Reference numbers 20, 22, and 24 show the interior seals. The interior boundaries can extend from about the bottom of the envelope to a level below the lower lip of the front panel to which the reclosable means is Mo-4406 4-attached. Reference numbers 40, 42 or 44 illustrate the level of the interior boundaries. Typically, the interior boundaries are such that they define a retaining compartment for the pouches. In essence, the compartments are of dimensions that would enable one to insert and 5 remove the pouches from the compartments.
The outside boundaries are defined by the side ends and top and bottom ends of the envelope. Reference numbers 26 and 28 show the left and right side ends of the envelope. Reference numbers 30 and 32 show the bottom and top ends, respectively. The outside boundaries can 10 be formed by any convenient means. Preferably, they can be formed by end-lapping and fastening one or two pieces of material. Preferably, fastening is done by heat sealing. In the present embodiment, the bottom end of the envelope is defined by a folded end of a piece of material. The material is folded to form the back and front panels of the 15 envelope. The top end is formed by end-lapping and fastening the material of the back panel to a strip of material 31 that forms the top section of the front panel. The strip extends sufficiently downward to provide a lip to which the reclosable means is fastened. Preferably, fastening is by heat sealing. Outer sides of the compartments are 20 illustrated by Fig. 1, reference numbers 50, 52, 54, and 56, and Fig 8, reference numbers 57, 58, and 59. The inner sides of the compartments are illustrated by Fig. 9, reference numbers 51 and 53.
The envelope can be made reclosable by means such as a zipper comprising a zipper track 38 and a zipper lock 36. In the present 25 embodiment of the invention, the reclosable means is a zipper comprising a low density polyethylene double-track with nickel zipper lock. Another reclosable means that can be used comprises a pressure sensitive "zip-lock" mechanism. The reclosable means can be located in a position that is about 1 to 2 inches from the top of the envelope. In the present q Z~ ~2~ ~1 .
Mo-4406 -5 embodiment of the invention, the reclosable means is widthwise disposed over the section of the envelope that is above the height of the interior seals. This would allow one to insert the pouches in the compartments, close and open the envelope to conveniently retrieve the pouches. The 5 reclosable means can be fastened to the lips or flaps of the front panel of the envelope by any convenient means. Fastening should be such that it does not compromise the protection of the pouches by, say, moisture penetration. For example, the zipper can be attached to the lips by gluing, sewing or heat sealing.
Fig. 4 represents the back view of the compartmentalized envelope. The back view is essentially the same as the front view except that, usually, the back panel of the envelope does not have a reclosable means.
Fig 9, reference number 62, illustrates a cross section of the 15 pouch in a compartment at section 9-9. The contents of the pouch 60 are typically chemicals and preferably agricultural chemicals. The pouch can be made of a material, p~t:ferably, a film of material having the following characteristics. The pouch can be made of one or more pieces of material by folding and/or lapping and sealing the ends of the material.
20 Broadly, the material of the pouch can be characterized as being sufficiently durable to remain intact during shipping and storage. The material must have sufficient moisture barrier to protect the contents of the pouch. Specific but non-limiting examples of the material can be selected from the group consisting of polyvinyl alcohol, polyethylene, 25 polyester, polypropylene, polyolefin and a mixture thereof. The dimensions of the material would depend on the tvpe of material and the service conditions. Illustratively, a pouch that is made of polyvinyl alcohol material would have outside dimensions of about 4 to 10 inches in length, 2 to 6 inches in height and 1 to 2 inches in thickness.
9 2 ~ 1 Mo-4406 -6-The pouch is preferably water-soluble. In the practice of the invention, the water-soluble pouches can be removed from the compartments and placed in a mixing vessel or an application vessel.
The water soluble pouches are such that they can dissolve in water over 5 a period of 1 to 5 and preferably 1 to 2 minutes. Examples of the water soluble pouches are those made of materials selected from the group consisting of polyvinyl alcohol, polyethylene oxide and methyl cellulose.
In preparing a pouch containing the chemical, the pouch can be filled with predetermined amounts of chemicals by using any effective 10 filling means, and sealed by any sealing means. Once the pouch is filled, it is sealed in such a manner that would prevent leakage of the chemical.
Fig. 10, reference number 46 illusllales the space between the top of seal 40 and the top end of the bag 30. This space is disposed 15 widthwise and comprises an expansion space over the compartments.
The expansion space allows one to easily insert and retrieve the pouches from the compartments of the envelope.
An illustrative but non-limiting description of the invention is provided as follows. The reclosable compartmentalized envelope can be 20 made of: a 48 gauge chemically treated polyester number 12, (white) low density polyethylene, or 0.0003 aluminum foil such as is available as a laminated composite from Bell Flexible Packaging of Columbus, Georgia in the United States with a number 22, linear, low density polyethylene sealant layer. The envelope has two side seals, each 8-3/4 inches long 25 by 3/8 of an inch wide. Additionally, the envelope has three interior seals that cause formation of four compartments. Each of the three seals is about 1/4 inch wide. A pull-slide double track zipper is located at a position that is one inch from the top of the envelope and is approximately 1/4 inch wide. The zipper closes from right to left. The 2 ~ 11 Mo4406 -7-bottom of the envelope is folded and the top has an 1/8 inch lip with the back panel of the envelope being 1/8 inches longer than the front panel.
The compartments of the formed envelope are filled with the pouches, typically one per compartment, and reclosably sealed. Because 5 of the reclosability of the envelope, the separated compartments provide continuous protection for the unused pouches even after the initial opening of the envelope. Because the compartments are separated, handling of a pouch in a compartment is independent of handling of another pouch. This independence in handling can prevent inadvertent 10 contact by wet hands or contact by splashing. Also, the independence in handling would prevent contamination of the remaining chemical after the use of a portion thereof from the same container envelope. The compartments can also maintain the pouches in a uniform shape (flat and rectangular) which improves the packing in a container of multiple 15 envelopes. As would be realized from the foregoing, the invention provides a packaging system that can be used to securely contain chemicals and yet provide a facile means of removing and incrementally using the chemicals.
These and other aspects of the invention are illustrated by the 20 following non-limiting example of the compartmentalized envelopes and methods of preparing and using the same.
EXAMPLES
A composite polyolefin/aluminum foil material was used in making the reclosable compartmentalized envelope of the invention as follows.
25 The material having a film thickness of 0.004 inch (4 mils) was employed in making the envelope. The envelope was made by end-lapping two pieces of the material of dimensions s~lrricie"t to produce the envelope.
The ends of the pieces of material are heat sealed by using heat bar sealing methods. At a position that is about 1 inch from the top, the 30 envelope was zippered with a polyethylene double track zipper.
Mo4406 -8-Thereafter, compartments were formed in the envelope by heat bar type heat sealing.
The pouches were prepared with a water-soluble film roll stock on a vertical "form-fill-seal" machine by forming bottom horizontal heat seal 5 and vertical back heat seal, filling with product while pulling the film pouch, and forming horizontal top heat seal. Thereafter, the filled pouches were sealed.
The sealed pouches were placed in compartments of the envelope which were then zippered to close (optionally, with a tamper indicator 1 0 seal).
Although the invention has been described in detail in the foregoing for the purpose of illustration, it is to be understood that such details are solely for that purpose, and that variations can be made therein by those skilled in the art without departing from the spirit and 15 scope of the invention, except as it may be limited by the claims.

DETAILED DESCRIPTION OF THE INVENTION
The reclosable compartmentalized envelope of the present invention is generally illustrated by Figs. 1-10 The envelope Fig. 1, reference number 11, can be formed with one or more pieces of material 0 2~ ~922 1 Mo-4406 -3-by: folding and/or lapping and sealing the ends of the material to form the envelope. The material is sealed on the outside to forrrl the outside boundaries and on the inside to form the inside boundaries defining the compartments. The front end of the envelope is provided with a reclosable means by attaching it to lips on the front panel of the envelope. Generally, the material useful herein is sufficiently durable to remain intact during shipping, storage and use of the envelope. Further, the material must have sufficient moisture barrier to protect the pouches contained therein. Also, the material is such that it can be equipped with or adapted to have a means of reclosing the envelope. Typically, the material comprises a flexible film. Specific but non-limiting examples of the material can be selected from the group consisting of: polyethylene, polyester, polyamide, polypropylene, ethylene vinyl alcohol, aluminum foil and a mixture or composite thereof. The dimensions of the envelope depend on the type of material and the service conditions of the envelope. Illustratively, an envelope that is made of a polyolefin material would have outside dimensions of about 16 to 24 inches in length, 6 to 10 inches in height and 1 to 2 inches in thickness (expansion) when the envelope contains filled pouches.
The envelope is defined by its outside boundaries and inside boundaries that form two or more compartments as illustrated by reference numbers 12, 14, 16, and 18 which are separated from each other. The separation between the compartments can be provided by fastening the material of the front panel to the ",aterial of the back panel of the envelope, at desired inside boundaries 41, 43, and 45. Any effective fastening means, such as sealing, can be used to provide the separation. Preferably, the sealing can be done by heat-sealing.
Reference numbers 20, 22, and 24 show the interior seals. The interior boundaries can extend from about the bottom of the envelope to a level below the lower lip of the front panel to which the reclosable means is Mo-4406 4-attached. Reference numbers 40, 42 or 44 illustrate the level of the interior boundaries. Typically, the interior boundaries are such that they define a retaining compartment for the pouches. In essence, the compartments are of dimensions that would enable one to insert and 5 remove the pouches from the compartments.
The outside boundaries are defined by the side ends and top and bottom ends of the envelope. Reference numbers 26 and 28 show the left and right side ends of the envelope. Reference numbers 30 and 32 show the bottom and top ends, respectively. The outside boundaries can 10 be formed by any convenient means. Preferably, they can be formed by end-lapping and fastening one or two pieces of material. Preferably, fastening is done by heat sealing. In the present embodiment, the bottom end of the envelope is defined by a folded end of a piece of material. The material is folded to form the back and front panels of the 15 envelope. The top end is formed by end-lapping and fastening the material of the back panel to a strip of material 31 that forms the top section of the front panel. The strip extends sufficiently downward to provide a lip to which the reclosable means is fastened. Preferably, fastening is by heat sealing. Outer sides of the compartments are 20 illustrated by Fig. 1, reference numbers 50, 52, 54, and 56, and Fig 8, reference numbers 57, 58, and 59. The inner sides of the compartments are illustrated by Fig. 9, reference numbers 51 and 53.
The envelope can be made reclosable by means such as a zipper comprising a zipper track 38 and a zipper lock 36. In the present 25 embodiment of the invention, the reclosable means is a zipper comprising a low density polyethylene double-track with nickel zipper lock. Another reclosable means that can be used comprises a pressure sensitive "zip-lock" mechanism. The reclosable means can be located in a position that is about 1 to 2 inches from the top of the envelope. In the present q Z~ ~2~ ~1 .
Mo-4406 -5 embodiment of the invention, the reclosable means is widthwise disposed over the section of the envelope that is above the height of the interior seals. This would allow one to insert the pouches in the compartments, close and open the envelope to conveniently retrieve the pouches. The 5 reclosable means can be fastened to the lips or flaps of the front panel of the envelope by any convenient means. Fastening should be such that it does not compromise the protection of the pouches by, say, moisture penetration. For example, the zipper can be attached to the lips by gluing, sewing or heat sealing.
Fig. 4 represents the back view of the compartmentalized envelope. The back view is essentially the same as the front view except that, usually, the back panel of the envelope does not have a reclosable means.
Fig 9, reference number 62, illustrates a cross section of the 15 pouch in a compartment at section 9-9. The contents of the pouch 60 are typically chemicals and preferably agricultural chemicals. The pouch can be made of a material, p~t:ferably, a film of material having the following characteristics. The pouch can be made of one or more pieces of material by folding and/or lapping and sealing the ends of the material.
20 Broadly, the material of the pouch can be characterized as being sufficiently durable to remain intact during shipping and storage. The material must have sufficient moisture barrier to protect the contents of the pouch. Specific but non-limiting examples of the material can be selected from the group consisting of polyvinyl alcohol, polyethylene, 25 polyester, polypropylene, polyolefin and a mixture thereof. The dimensions of the material would depend on the tvpe of material and the service conditions. Illustratively, a pouch that is made of polyvinyl alcohol material would have outside dimensions of about 4 to 10 inches in length, 2 to 6 inches in height and 1 to 2 inches in thickness.
9 2 ~ 1 Mo-4406 -6-The pouch is preferably water-soluble. In the practice of the invention, the water-soluble pouches can be removed from the compartments and placed in a mixing vessel or an application vessel.
The water soluble pouches are such that they can dissolve in water over 5 a period of 1 to 5 and preferably 1 to 2 minutes. Examples of the water soluble pouches are those made of materials selected from the group consisting of polyvinyl alcohol, polyethylene oxide and methyl cellulose.
In preparing a pouch containing the chemical, the pouch can be filled with predetermined amounts of chemicals by using any effective 10 filling means, and sealed by any sealing means. Once the pouch is filled, it is sealed in such a manner that would prevent leakage of the chemical.
Fig. 10, reference number 46 illusllales the space between the top of seal 40 and the top end of the bag 30. This space is disposed 15 widthwise and comprises an expansion space over the compartments.
The expansion space allows one to easily insert and retrieve the pouches from the compartments of the envelope.
An illustrative but non-limiting description of the invention is provided as follows. The reclosable compartmentalized envelope can be 20 made of: a 48 gauge chemically treated polyester number 12, (white) low density polyethylene, or 0.0003 aluminum foil such as is available as a laminated composite from Bell Flexible Packaging of Columbus, Georgia in the United States with a number 22, linear, low density polyethylene sealant layer. The envelope has two side seals, each 8-3/4 inches long 25 by 3/8 of an inch wide. Additionally, the envelope has three interior seals that cause formation of four compartments. Each of the three seals is about 1/4 inch wide. A pull-slide double track zipper is located at a position that is one inch from the top of the envelope and is approximately 1/4 inch wide. The zipper closes from right to left. The 2 ~ 11 Mo4406 -7-bottom of the envelope is folded and the top has an 1/8 inch lip with the back panel of the envelope being 1/8 inches longer than the front panel.
The compartments of the formed envelope are filled with the pouches, typically one per compartment, and reclosably sealed. Because 5 of the reclosability of the envelope, the separated compartments provide continuous protection for the unused pouches even after the initial opening of the envelope. Because the compartments are separated, handling of a pouch in a compartment is independent of handling of another pouch. This independence in handling can prevent inadvertent 10 contact by wet hands or contact by splashing. Also, the independence in handling would prevent contamination of the remaining chemical after the use of a portion thereof from the same container envelope. The compartments can also maintain the pouches in a uniform shape (flat and rectangular) which improves the packing in a container of multiple 15 envelopes. As would be realized from the foregoing, the invention provides a packaging system that can be used to securely contain chemicals and yet provide a facile means of removing and incrementally using the chemicals.
These and other aspects of the invention are illustrated by the 20 following non-limiting example of the compartmentalized envelopes and methods of preparing and using the same.
EXAMPLES
A composite polyolefin/aluminum foil material was used in making the reclosable compartmentalized envelope of the invention as follows.
25 The material having a film thickness of 0.004 inch (4 mils) was employed in making the envelope. The envelope was made by end-lapping two pieces of the material of dimensions s~lrricie"t to produce the envelope.
The ends of the pieces of material are heat sealed by using heat bar sealing methods. At a position that is about 1 inch from the top, the 30 envelope was zippered with a polyethylene double track zipper.
Mo4406 -8-Thereafter, compartments were formed in the envelope by heat bar type heat sealing.
The pouches were prepared with a water-soluble film roll stock on a vertical "form-fill-seal" machine by forming bottom horizontal heat seal 5 and vertical back heat seal, filling with product while pulling the film pouch, and forming horizontal top heat seal. Thereafter, the filled pouches were sealed.
The sealed pouches were placed in compartments of the envelope which were then zippered to close (optionally, with a tamper indicator 1 0 seal).
Although the invention has been described in detail in the foregoing for the purpose of illustration, it is to be understood that such details are solely for that purpose, and that variations can be made therein by those skilled in the art without departing from the spirit and 15 scope of the invention, except as it may be limited by the claims.
