Flash with a refillable cup

Abstract

A flask is provided with a refillable cup having an external jar (2) and an inner internal cup (3) to contain the product. The inner internal cup (3) is removable, through the mouth (20) of the external jar (2) in order to be able to refill or replace it. The flask has a removable fastener between the cup (3) and the jar (2) that stay hidden and include a resistance point (54) which ensures the fastening between both elements and prevents the elements from being separated while not proceeding to the express handling thereof by operating thereon in order to overcome the resistance point (54).
