Method for delivering a volatile fluid to the atmosphere

A method for delivering a volatile fluid to the atmosphere comprising the steps of:

• a. providing a device having an x-axis, a y-axis, a z-axis, wherein said device further comprises:
• i. a reservoir for containing a volatile fluid;
• ii. a multi layer semi-rigid sheet comprising a first sealant layer sealed to said reservoir, a barrier layer sealed to said first sealant layer, a structural layer sealed to said barrier layer, 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
• iii. a vapor permeable membrane heat-sealed to said semi-rigid sheet.
• b. breaching said differential score to release said volatile fluid from said reservoir and to contact said volatile fluid with said vapor permeable membrane thereby diffusing said volatile fluid to the atmosphere.

A method for delivering a volatile fluid to the atmosphere comprising the steps of:

• a. providing a device having an x-axis, a y-axis, a z-axis, a sealed edge, and a tab extending from said device, wherein said device is contained in a housing having a notch, and wherein said device further comprises:
• i. a flexible sheet;
• ii. a multi layer semi-rigid sheet sealed to said flexible sheet to form a reservoir, wherein said semi-rigid sheet comprises a structural layer, a differential score defining a scored region and an un-scored region, 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 region is about 5 mm to about 15 mm from said sealed edge;
• and
• iii. a vapor permeable membrane sealed to said semi-rigid sheet;
• b. inserting said tab into said notch, thus, breaching said differential score and releasing said volatile fluid from said reservoir to said vapor permeable membrane for diffusion of said volatile fluid to the atmosphere.
