Abstract: A rewritable tablet book includes a front cover, a back cover, and a spine connecting the back cover to the front cover. The rewritable tablet book includes a rewritable surface that extends across an inside surface of the front cover, the spine, and the back cover. The rewritable tablet book also includes a fastener. The fastener joins the front cover to the back cover in a closed position to hold a marker in a hollow region defined by the rewritable surface and the spine. The marker is locked in the hollow region.

Abstract: A foldable open-top container is constructed from a single sheet 1 of material having fold lines (4,7) enabling the sheet to be transformed into the container by folding. The container has a base (3) and side walls (16) that extend from the base and define a rim (5). The side walls are joined at each end by corners (11). Each corner is a flap formed from the two fold lines. The flap has an outside part (8c) that extends into one side wall, an inside part (8b) that extends into the adjoining side wall, and a middle part (8a) between the inside and outside parts. A first integral formation on one of said parts (notch 12) is interlocked with another of said parts (notch 14) to retain the flap in a folded condition.

Abstract: The invention provides a foldable cup comprising a sheet of plastics material (1) having a container piece (2) integral with at least one handle piece (3), said container piece (2) having fold lines (7, 10) enabling it to be transformed from a flat condition into a folded container, and said handle piece (3) having fold lines enabling the piece to be formed into a handle extending from and held in position relative to the container. When transformed from a flat to a folded condition, the container is folded in such a way as to provide leak proof seals, enabling the cup to safely hold both liquids and solids.
