Claims

[Scope of Claim for Utility Model Registration] (1) A sampling bag that has a sealable opening at one end and surrounds the object of aroma sampling so as not to damage it, thereby securing a substantially sealed space around it; It consists of a collection adsorption tube filled with an adsorbent that adsorbs the collected aroma components, a small battery-driven pump, the sampling bag, the collection adsorption tube, and a connecting member that connects the collection adsorption tube and the pump. . A head space collection device characterized in that the sampling bag is made of a film made of a material that is flexible and does not volatilize odor components by itself and does not adsorb odor components. (2) The exhaust system of the pump according to claim 1 and the sampling bag are connected to form a circulation flow path for circulating the atmospheric gas in the sampling bag via the pump, while the sampling bag and the pump are connected to each other. A head space collection device characterized in that a cleaning adsorption tube filled with an adsorbent for adsorbing pollutants is provided between the exhaust system and the exhaust system. (3) Claim 1 characterized in that the collection suction tube is detachably connected to the sampling bag and the connecting member, and has a structure that can be sealed by attaching lid members to both ends of the tube after removal. Or the head space collection device according to 2. (4) The head space collection device according to any one of claims 1 to 3, wherein the opening of the sampling bag is provided with a sealing means that can open and close the opening as desired. (5) The headspace collection device according to any one of claims 1 to 4, wherein the sampling bag is manufactured by Tedler. (6) Any one of claims 1 to 5, characterized in that the sampling bag is provided with a core material that spreads the sampling bag from the inside and prevents the sampling bag from touching the object for aroma collection and secures a certain space around the sampling bag. Headspace collection device as described. (7) The sampling bag, the collection adsorption tube,
A head space collection device characterized in that a cleaning adsorption tube, a small pump, a connecting member, and a core material are housed in one carrying case in a disassembled state.
