Device for containing and releasing a sample material

A device for containing a sample material comprising:

• a first structural layer having an inner surface an outer surface, and an edge;
• a second structural layer having an inner surface and an outer surface, wherein the second structural layer is separate from the first structural layer, and wherein the outer surfaces of the first structural layer and the second structural layer comprise an adhesive;
• a frangible layer attaching the inner surface of the first structural layer to the inner surface of the second structural layer to form a sampler, wherein the frangible layer is set back from the first structural layer edge a first distance, and the adhesive on the outer surface of the first structural layer is set back from the first structural layer edge a second distance that is less than the first distance;
• a sample material contained in the frangible layer;
• and
• a printed carrier substrate comprising a first panel and a second panel, wherein the first panel and the second panel are continuous and divided by a fold line, and the outer surface of the second structural layer of the sampler is attached to the second panel of the substrate such that the edge of the first structural layer is the side of the first structural layer that is furthest from the fold line,
• wherein when the substrate is folded at the fold line the adhesive on the outer surface of the first structural layer contacts the first panel thereby attaching the first panel of the substrate to the outer surface of the first structural layer, and
• wherein upon application of peel force stress between the first structural layer and the second structural layer, the frangible layer breaks for access to the sample material.
