Device for delivering a volatile fluid to the atmosphere

A device for delivering a volatile fluid, wherein said device comprises an x-axis, a y-axis, a z-axis, and wherein said device further comprises:

• a. a reservoir for containing a volatile fluid;
• b. a multi layer semi-rigid sheet comprising:
• i. a first sealant layer sealed to said reservoir,
• ii. a barrier layer sealed to said first sealant layer,
• iii. a structural layer sealed to said barrier layer,
• iv. optionally, a second sealant layer sealed to said structural layer,
• wherein said multi layer semi-rigid sheet further comprises a differential score comprising an upper incision and a lower incision, said upper incision has a depth along said z-axis that transverses at least about 50% of said structural layer and said lower incision has a depth along said z-axis that transverses at least about 50% of said first sealant layer;
• and
• c. a vapor permeable membrane heat-sealed to said semi-rigid sheet.

A device for delivering a volatile fluid, wherein said device comprises an x-axis, a y-axis, a z-axis, and a sealed edge, and wherein said device further comprises:

• a. a flexible sheet;
• b. a multi layer semi-rigid sheet sealed to said flexible sheet to form a reservoir for containing a perfume mixture, wherein said semi-rigid sheet comprises:
• i. a first sealant layer heat-sealed to said flexible sheet, wherein said first sealant layer comprises a material selected from the group consisting of polyethylene, polypropylene, polyethylene terpthalate, and combinations thereof, and wherein said first sealant layer has a thickness along said z-axis of at least about 15 microns,
• ii. a perfume resistant barrier layer sealed to said first sealant layer, wherein said barrier layer comprises a material selected from the group consisting of polyethylene, ethylene vinyl alcohol, and combinations thereof, and wherein said perfume resistant barrier layer comprises a thickness along said z-axis from about 10 microns to about 15 microns;
• iii. a structural layer sealed to said perfume resistant barrier layer, wherein said structural layer comprises a plastic selected from the group consisting of polystyrene, polyvinyl chloride, acrylonitrile butadiene styrene, polypropylene, polyethylene, polyethylene terpthalate, and combinations thereof, and wherein said structural layer comprises a thickness along said z-axis from about 350 microns to about 700 microns;
• iv. a differential score defining a scored region and un-scored regions, wherein said differential score comprises at least one incision having a depth along said z-axis that transverses at least about 50% of said structural layer, and wherein said un-scored regions are about 5 mm to about 15 mm from said sealed edge;
• and
• v. optionally, a second sealant layer heat-sealed to said structural layer comprising a material selected from the group consisting of polyethylene, polypropylene, polyethylene terpthalate, and combinations, and wherein, when said second sealant layer is present, said second sealant layer comprises a thickness along said z-axis of at least about 15 microns, and wherein said differential score fully transverses said second sealant layer;
• and
• c. a microporous membrane heat-sealed to said semi-rigid sheet.
