Abstract

A pouch package, containing a volatile solution-impregnated patch, is made of a peelable barrier film. The pouch envelops an absorbent substrate saturated preferably with bug repellent fluid. A PSA (pressure sensitive adhesive) coated backing film is laminated to the absorbent substrate. The backing film has a connecting portion which is peelably sealed to the inside of the pouch. When the pouch is peeled open, the PSA coated backing film is exposed and placed against a target surface, such as a patch wearer'"'"'s clothing. Finally, the side of the pouch facing the absorbent substrate is peeled off the backing film connecting portion to expose the absorbent substrate. A key to functionality of the pouch package is differential adhesion. First, the pouch barrier film must be peelable from itself, yet it must not adhere to the pressure sensitive adhesive on the backing film. A release paper may be used to cover the PSA when peeling the pouch open. Second, the pouch film must be peelable from the backing film connecting portion without disturbing the bond between the fastening surface and the target surface. Third, the backing film must be laminated to the absorbent substrate more strongly than the PSA adheres to the backing film, so that when the patch is removed from the target surface, the PSA stays with the patch.

Claims

1. A package containing a bug repellant-impregnated substrate and enabling a user to apply said substrate to a target without contacting said substrate, said package comprising:

a) an impermeable barrier film pouch enclosing said substrate, said pouch having a top film, a bottom film, and a peelable seal between said top film and said bottom film to seal said pouch in an air-tight manner, said pouch having opening tabs, said substrate being connected to said pouch such that when said pouch is peeled open, said substrate may be positioned by manipulating said pouch; and

b) an impermeable backing film laminated to said substrate, said backing film having a fastening surface opposite said substrate, and a connecting portion being peelably attached to said pouch, said fastening surface being exposed for attachment to said target when said bottom film is peeled away from said top film.

2. A package containing a bug repellant-impregnated substrate and enabling a user to apply said substrate to a target surface without contacting said substrate, said package comprising:

a) an impermeable backing film laminated to said substrate, said backing film having a fastening surface opposite said substrate and a connecting portion; and

b) an impermeable film pouch enclosing said patch, said pouch having a top film, a bottom film, and a peelable seal between said top film and said bottom film to seal said pouch in an air-tight manner, said top film and said bottom film each having an opening tab, each opening tab being positioned so that said pouch may be opened by pulling said opening tabs apart, said top film having an inner surface which is peelably sealed to said connecting portion of said backing film such that when said pouch is peeled open to expose said fastening surface, said connecting portion remains attached to said inner surface of said top film, said fastening surface being more strongly attracted to said backing film than to said bottom film, so that said pouch may be peeled open without interference from said fastening surface.

3. The package of claim 2 wherein said fastening surface adheres to said backing film and to said target surface more strongly than said connecting portion of said backing film adheres to said inner surface of said top film, so that said pouch may be removed from said connecting tab without pulling said patch off said target surface.

4. The package of claim 2 wherein said fastening surface adheres more strongly to said backing film than to said target surface, so that when said patch is removed from said target surface, said fastening surface remains on said backing film.

5. A package containing a bug repellant-impregnated substrate and enabling a user to apply said substrate to a target surface without contacting said substrate, said package comprising an impermeable film pouch enclosing said substrate, said pouch having a top film, a bottom film, and a peelable seal between said top film and said bottom film to seal said pouch in an air-tight manner, said top film and said bottom film each having an unsealed opening tab extending beyond said peelable seal, said opening tabs being positioned so that said pouch may be opened by pulling said opening tabs apart, said bottom film of said pouch being laminated to said substrate;

said bottom film having a fastening surface opposite said substrate, said fastening surface having an adhesive for attachment to said target, said adhesive having a stronger bond than said peelable seal, so that said top film may be removed from said bottom film without pulling said pouch off said target surface.

6. The package of claim 5 wherein said attachment means adheres to said bottom film more readily than to said target surface, so that removal of said bottom film by lifting said opening tab also removes said attachment means.
