Abstract:
A tool for retaining freshness, comprising an adsorbent adsorbing a freshness retaining liquid and film-like covers having high impermeability against the gas of the freshness retaining liquid and covering the adsorbent from the outside with the sizes thereof larger than that of the adsorbent. The covers are formed in the sizes larger than that of the adsorbent, the outer edge sides thereof are extended to the side of the adsorbent in the state of holding the adsorbent from the upper and lower sides to form skirt parts separated from each other in the vertical direction, and an opening for vaporization allowing the vaporization of the freshness retaining liquid to be gradually vaporized from the adsorbent to the outside is formed between the upper and lower skirt parts. Layers having a function for adsorbing and diffusing liquid matter adhered onto the surfaces of the film covers thereinto are formed on both or one of the upper and lower film covers forming the skirt parts on the side thereof coming into contact with the adsorbent.
