A sampler pouch (10) having a lower barrier layer (20) and an upper barrier layer (30) peelably sealed to the lower barrier layer to form a cavity and a fluidic sample material absorbed within an internal supportive structure (40) within the cavity. The internal supportive structure is inert and substantially retains the sample material when subjected to compressive forces, thereby reducing internal pressure against the peel seal (60) and allowing for the use of low strength peel seals. The upper and lower barrier layers extend beyond the area of the cavity and peel seal in an area defining a peel tab (70).

La présente invention concerne une poche d'échantillonneur (10) constituée d'une couche barrière inférieure (20), d'une couche barrière supérieure (30), formant un joint étanche, décollable, avec la couche barrière inférieure de façon à constituer une cavité, et une matière d'échantillon fluidique absorbée dans une structure de support interne (40) de la cavité. La structure de support interne est inerte et retient sensiblement la matière d'échantillon lorsque celle-ci est soumise à des forces de compression, réduisant ainsi la pression interne contre le joint étanche (60) décollable et permettant l'utilisation de joints étanches décollables de faible résistance. Les couches barrières inférieures et supérieures s'étendent au-delà de la zone de la cavité et du joint étanche dans une zone définissant une languette décollable (70).
