A carton blank may be formed having at least one score line therein.

A second layer of material may overlay at least a portion of the first layer, including the score line, thus defining an overlaid score area.

The section is defined by a notched line, and the opening is defined by a cut.

The said score line (6), comprises residual matter thickness that is smaller than the thickness of the card body.

The neck portion (9) terminates in a generally plane surface (10) having a score line (15) marking a removable opening.

The card body comprises a score line (6) surrounding the electronic module (4) in order to define the second card format (3).

It is thus possible to temporarily stop an opening process which is difficult to control after initial rupturing of the line of indentation (21; 31).

When the cap (4) is turned, the dent (5) breaks the score line (15) allowing the opening to be formed for removing the contents.

A paperboard sheet having a scoreline (38) defining a narrow flap portion (28) on one side thereof and a body portion (30) on the other side.

Within its surface, the lid comprises a breakable region which is delimited by a notched line (103) and is surrounded by a cylindrical central wall (106) of a central enclosure (W).

With the sheet and dividers removed from the packaging, the flap portion is folded up generally ninety degrees on the scoreline to define a guide tray (32).

In addition, the bottom panel (14) finger holes (62) have a straight transverse inner edge connected to a cover tab (62) along a score line (64).

When the blank (10) is bent, a portion of the total deflection is absorbed by each score line (30) so that the resulting container edge is a gradual curve rather than a single sharp crease.

Said area is situated in the surface of the top, can rupture and is smaller than the essentially flat surface.

The inventive top comprises an essentially flat surface (3, 10, 20, 30), and an area (4; 11; 33; 22) which is defined by a line of indentation (8; 11; 21; 31).
