STACK OF ACCORDION-FOLD LIGHT SHEET THAT HAS A DEVICE FOR CONNECTING TO ANOTHER STACK Russian patent published in 2018 - IPC A47K10/42 

FIELD: molding.

SUBSTANCE: stack (1) of sheet material in the form of sanitary articles placed in the dispenser is proposed. Stack comprises at least one light solid sheet material (2, 3) accordion-fold along transverse fold lines (4), with panels, having length (L) in the direction of the fold lines and a width (W) in a direction perpendicular to the lines fold, the panels are stacked one on top of another and form height (H) of the stack from first end surface (5) to second end surface (6). First end surface (5) comprises first coupling device (11a), and second end surface (6) comprises second coupling device (11b). One of first and second couplers (11a, 11b) comprises first (51) and second (52) mechanical connecting structures, which are two corresponding structures, each of which can form a mutual mechanical connection with another structure and can not form a mutual mechanical connection with an identical structure.

EFFECT: as a result, at least one of first and second coupling devices (11a, 11b) can form a mechanical connection to another connecting device of another stack of web material, the first and/or second mechanical connecting structures present in the other coupling device.
