It is a rigid or semi-rigid container that may have one or more holes covered by a prefabricated
elastic membrane made of food-grade
silicone, the same type used in the preparation and decoration of cakes, chocolates, candies, fondant, among others. Once applied and the hole(s) of the container are closed, it helps create an airtight seal and also allows the user to examine the food contained within by touch without having to open it, which translates into better preservation, thus avoiding constant and
prolonged exposure to any external agents and / or conditions, such as:
humidity,
bacteria, and especially air, and with the latter, inevitably,
oxygen itself.
