• Thermoformed semi-rigid containers made with a sterilizable polymeric material, such as PET, are known on the one hand. These containers are for example closed by screwed or snap-on plugs which must be handled by a user for the opening of the container, which has a number of disadvantages with respect to asepsis.
• Flexible containers are also known, formed by the joining of at least two sheets in the vicinity of their periphery (or by a folded sheet whose two portions are secured to one another), so as to form two side walls. and, optionally, a bottom for maintaining the vertical container.
