A pill pack card (1) has three pieces (2,3,4) connected by a single fold (5) between pieces (2&3) and a double fold (6,7) between pieces (3&4). The inner face (8) of card is coated with adhesive. The card piece (2) has an array of (28) apertures (10) for the (28) compartments (11) of a vacuum formed tray (12). On population, the card piece (3) is folded onto the tray, with the film coming into adherence with the lands of the tray. Thus the pills are contained. The apertures (16) in the second, central card piece (3) are crossed by respective tabs (21). The middle sheet piece (3) has a large rectangular aperture (31) with an up-standing wide tongue (32). The first sheet piece (2) has a corresponding aperture (312). Printed onto the outer face (18), again typically by high-speed flexo-graphic printing, is a series of conductive lines (33) with a linear series of contacts (34) extending onto the tongue (32). The conductive lines are over printed with background colour (35), typically white, onto which the graphic printing (19) is printed. The layout of the conductive lines is that a common contact 36 leads to a common lines (37), extending via branches (38) to one or other of the perforated top and bottom portions (24) of each tab. On each tab, between the wide portions at the perforations, a tab-crossing line section (39) is provided. It has wide ends (40) to ensure conduction prior to tearing of the tabs perforations. The arrangement is that from each tabs unique contact, there is a continuous circuit to the common contact across the tab. Breaking of the circuit, as in breaking of the tab to take the pills in its compartment breaks the circuit. This can be detected by an interrogatory circuit (42), also referred to as a "MARS tag", connected to the contacts.La présente invention concerne une carte 1 sous forme de boîte pour pilules comportant trois éléments 2, 3, 4 reliés par un pli simple 5 situé entre les éléments 2 et 3 et un pli double 6, 7 situé entre les élémen
