Abrégé

The present invention uses a simple and inexpensive configuration to suppress changes to the taste, fragrance, flavor, and like of the contents of a container after unsealing. This deterioration prevention member 1 is formed such that the entire peripheral edge thereof approaches or comes into contact with the inner side of a transverse cross-section of the torso portion of the container, and can be deformed so as to be inserted from the opening of the container through the neck portion to the torso portion. The deterioration prevention member 1 is formed such that the longitudinal cross-section shape of the top portion 11 thereof is a roughly mountain-like shape descending gradually toward the peripheral edge 11b with the center portion 11a as the highest point, and such that the longitudinal cross-section shape of the bottom portion 12 thereof is a roughly inverse mountain-like shape rising gradually toward the peripheral edge 12b with the center portion 12a as the lowest point.
