Treat cone maker
Treat cone template
A curved sector that rolls into a cone, with a glue strip along one edge. Pointed for confetti and sweets, or with a flat bottom so it stands.
How to fold it
Print at 100%. Text-weight paper (90 to 120 gsm) rolls smoothly; cardstock holds the shape for a heavy treat.
Cut along the curved edge and the two straight edges. There are no creases to make on the cone itself.
Fold the grey strip back once along its edge, then flatten it again; it only needs to bend, not crease.
Roll the paper into a cone with the printed side out, bringing the plain edge over the grey strip, and glue it down from the tip up.
For a flat bottom, fold the ring of small tabs in, put glue on them and press the round base on from below.
Fill it, and fold the rim over or tie it with ribbon. A row of cones stands well in a box with holes or a jar of rice.
How the template is drawn
The arc is the opening
The curved edge is exactly as long as the rim it becomes: 3.1416 × the opening (plus one board) = 220.2 mm (8.67 in) at 2.75 × 6.5 in.
Radius of the template
The sector is cut from a circle as big as the cone's slant: the square root of the rim's radius² + the height², 169 mm (6.65 in) here.
Sector angle
360° × the rim's radius ÷ the slant: 74.7° here. A short cone opens to a wide fan, a slim one to a narrow wedge. The height is kept at 1.4 times the opening or more, so it stays a cone you can hold and fill.
Glue strip
12 mm (0.47 in) wide at the rim, narrowing toward the tip so it stays inside the other edge. Under Settings it goes from 5 to 25 mm.
Flat bottom
The cup stops where it is 40% as wide as the rim. A base 1.1 in (27.9 mm) across is glued under a ring of 4.9 mm (0.19 in) tabs, each cut narrower at its ends so the ring folds in without overlapping.
Weddings, parties and gift bags
At a wedding, a cone of dried petals or confetti waits on each chair; line them up in a box with round holes. At a party, fill them with popcorn, sweets or nuts. A cone printed on patterned paper needs no decoration, and with the lines printed on the inside the pattern stays clean.
For snacks that should stand on the table, the popcorn box has a flat floor and an open top. Favors that should stay closed go in a pillow box or a gable box, and a pyramid box makes a pointed gift.
