  • the tab 24 is separated from the abutment 26, thereby allowing easy disengagement and removal of the lid 1 , and opening of the container 2.
  • This step is carried out with the user having no contact with the product in the container 2.
  • the package is divided into three elements: the peripheral portion 3" of the cover member 3, the container 2 and a structure that acts as a repositionable lid, which is composed of the central portion 3' of the cover member 3 and the stiffening member 4.
  • lid removal is a reversible step, which may be restored by the interlocking fit of the two interferences 7 and 23. Therefore, the lid can be repositioned for more effective preservation of the contents, after removal of the peripheral portion 3" of the cover member 3, i.e. after opening of the container 2.
  • closure device 1 comprises a substantially seamless cover element 3 which extends over a stiffening member 4.
