Two sheets of film element (4) are used to sandwich an adsorbing body (2) vertically to bond the two film elements (4) to the upper and lower surfaces of the adsorbing body (2). Skirt sections (4A) extending sidewise from the adsorbing body (2) are formed at the outer edge sides of respective film elements (4) to form vaporizing openings (8) between respective skirt sections (4A). A freshness preserving liquid impregnated in the adsorbing body (2) is gradually vaporized from the respective side surfaces (2A) of the adsorbing body (2) to the outside via the vaporizing openings (8), whereby it is possible to prevent the adsorbing body (2) of the freshness preserving gadget (1) from directly touching foods and preserve the freshness of foods constantly over an extended period. Selon l'invention, deux éléments pelliculaires (4) sont utilisés pour envelopper verticalement un corps adsorbant (2), ces deux éléments pelliculaires (4) pouvant être liés aux surfaces supérieure et inférieure du corps adsorbant (2). Des parties de jupe (4A) se prolongeant vers l'extérieur à partir dudit corps adsorbant (2) sont formées au niveau des bords extérieurs des éléments pelliculaires (4) respectifs, d'où la formation d'ouvertures de vaporisation (8) entre ces parties de jupe (4A) respectives. Un liquide de conservation de fraîcheur imprégné dans le corps adsorbant (2) est progressivement vaporisé à partir des surfaces latérales (2A) respectives du corps adsorbant (2) vers l'extérieur via les ouvertures de vaporisation (2), d'où la possibilité d'empêcher le corps adsorbant (2) de ce dispositif de conservation de fraîcheur (1) d'être en contact direct avec des aliments, et de conserver la fraîcheur des aliments de manière constante pendant une durée prolongée.
