The packaging (1) comprises two generally hollow half-shells (2, 3) connected to each other in face-to-face relationship along their associated mouth edges (2', 3'). At least one, and preferably both of the aforesaid half-shells (2, 3) are closed by associated sealing sheets (6, 7), the connection of which on the facing surfaces leads to the connection of the two half-shells (2, 3). Both of the half-shells (2, 3) as well as the sealing sheet or sheets (6, 7) are provided with projections (20, 30, 60, 70) for use in opening the packaging, formed in correspondence with the mouth edges (2', 3') of the half-shells (2, 3) so as to be aligned with and superimposed over each other in the finished packaging. The connection of the sealing sheet or sheets (6, 7) to the associated half-shell (2, 3) also includes the aforesaid tongue parts which are not, however, affected by the connection of the two half-shells (2, 3) to each other. Consequently, the half-shells (2, 3) can be separated from each other without the risk of unwanted separation of the sealing sheet or sheets (6, 7) from the half-shells, which sheets are intended to be removed subsequently in order to access the contents of the half-shells (2, 3). The connection between the various parts is preferably achieved by means of ultrasonic sealing. <IMAGE>
