The present invention relates to an arrangement (10C) for preserving a product stored in a container with an opening, through which the product may be exposed to substances, which are harmful to the product or limit its preservability. The arrangement comprises a protecting device (11C) consisting of a bag of a flexible material, which is filled with a bag gas or a bag liguid (16C). The bag is so designed, that it, when brought into contact with an exposed surface of the product, changes its shape and spreads over substantially the entire exposed surface. The bag gas (16C) has a density, which is lower than the density of the stored product and which is higher than the density of said harmful substance/substances, for example air. The bag is designed to be re-usable, and is provided with application means (12C), for example comprising a helical element (13C) and a cork (14C). |
