<p>(A) The present invention relates to a technology for preventing carbon dioxide, which is dissolved in a carbonated drink, from escaping, thereby maintaining the feeling of refreshment for an extended period of time. (B) When a carbonated drink is contained in a conventional PET bottle, carbonic acid escapes gradually until the initial feeling of refreshment disappears. This is because, even when the bottle is sealed by a cap, each intake of the drink reduces the amount of the drink and increases the empty space inside the PET bottle, and more carbon dioxide escapes into the empty space. (C) The purpose of this patent is to maintain carbon dioxide, which is dissolved in a carbonated drink, for an extended period of time by forming folds such that the PET container can be compressed as much as the drink is consumed, thereby removing any space into which carbon dioxide can escape. (D) Removal of a space, into which carbon dioxide can escape, prevents escaping of carbon dioxide, which has been dissolved in the drink, and maintains the feeling of refreshment for an extended period of time, unlike the conventional method of sealing the bottle with a cap. Furthermore, the volume of the container is reduced as much as the drink is consumed, thereby improving portability.</p> |
