摘要:
A frame delimits an inside space and includes a peripherally closed side wall and two transverse openings or one transverse opening and a transverse end wall. It is capable of allowing the airtight engagement of the open free edge of a side wall in film form of a receptacle that is at least partially deformable. It is specially designed for the creation of a 3D container. The frame is also able to act as a support for at least one functional port or attachment port of a functional element. Its axial size is adequate for delimiting a space of a size that is at least equal to the axial dimension of the functional element, so that the latter can be completely housed within the inside space.
