A foldable utensil set including a bowl, dish, cup and spoon each foldable from a prescored plastic sheet which is semitransparent to allow angled folds at the corner to be visible as an aesthetic feature. The rims of the bowl and cup have portions at two different levels to prevent liquid from reaching the level of the mating snaps used to secure the bowl and cup in the folded condition. The spoon is folded from a flat sheet having two contiguous sections scored so as to form a handle and bowl portion when folded. The dish has side edges stiffened with a fold over section which also holds the folds in position. Oval shaped scoring is provided as an aesthetic feature and to aid in forming corners on the utensils when being folded.

The invention claimed is: 1. A foldable vessel for holding a liquid comprising a plastic sheet having a plurality of sides defining a perimeter edge of said sheet; a series of scored folding lines defining a closed shape at a central region of said plastic sheet having a number of sides corresponding to the sides of the perimeter edge of said plastic sheet and extending in the same general direction as a respective side of said perimeter edge; a pair of scored folding lines diverging out from each corner of said closed shape to said perimeter edge to form a series of triangular flaps so that when opposite pairs of vessel sides defined between said triangular flaps are folded up, said triangular flaps can be folded over onto one of said adjacent sides and an extension region of the other adjacent side wrapped over said triangular flap to form a rounded corner; further including a mating set of snaps at the top of at least two sets of said side extension regions and adjacent sides in an extension region covered by one of said triangular flaps, with an aligned clearance hole formed in each triangular flap wrapped over by a respective extension region to allow securement of said wrapped condition thereof by mating of said snaps through said clearance hole, the improvement comprising an outwardly curving upper perimeter edge of at least one pair of opposite sides and an inwardly curving perimeter edge on the other pair of opposite sides so that said lower and upper edges define a rim of said folded vessel, the mating snap sets located at a higher level region of said rim when said vessel is folded up to ensure that liquid cannot reach the level at which said mating snap sets are located. 2. A foldable vessel comprising a flat sheet of plastic material formed with a series of fold lines defining a rectangular bottom area with two fold lines radiating out from each corner to form triangular flaps at each corner and two pairs of opposite sides between each two of said triangular flaps, each side extending from a fold line defining said bottom area; said triangular flaps formed when each of said sides are bent up about said fold lines forming said center bottom area and wrappable about a respective one of a first pair of said two pairs of opposite sides and with a side extension region of a respective one side of a second pair of opposite sides wrapped over a respective triangular flap; a set of mating snaps at the top of at least two sets of sides and said side extension regions securing said flaps wrapped over said first pair of opposite sides; and a clearance hole in each triangular flap through which said sets of mating snaps engage each other; and, said second pair of opposite sides having rim regions intermediate said side extensions shorter than the height of said mating snaps above said bottom area to form a rim section lower than a rim section whereat said mating snaps and clearance holes are located whereby liquid introduced into said vessel cannot reach the level of said mating snaps and clearance holes. 3. The foldable vessel according to claim 2 wherein adjacent pairs of triangular flaps are wrapped over the same side lying between each of said pairs of flaps. 4. The foldable vessel according to claim 3 wherein each of said pairs of triangular flaps overlap when wrapped over said side and wherein only one of said side extension regions has a snap and the other of said side extension regions is formed with a clearance hole aligned with aligned clearance holes in each of said pair of triangular flaps through which said mating snaps engage each other. 5. The foldable vessel according to claim 3 wherein each of said second pair of opposite side extension regions have a snap mating with a respective one of snap located at the top of each of said first pair of opposite sides.
