Clamshell Carton with Shamrock Tag

 

Classic take out box is composed of lid and base 

assembled separately then joined across back. 

(Cut from two 8.5x11 cardstock or one 12x12.) 

Side latch tabs help to keep it closed. 

Layered medallion-shaped oval frame tag 

can adorn lid, or use a selected panel from 

holiday specialty print cardstock. 

Clamshell measures approx. 3.25” square across top, 

4.167” square at mid side, and 3” tall. 

ASSEMBLY: 1. Identify and cut the shapes:

A upper hull (with thumb cut out front)

B lower hull

C medallion base

D medallion frame

E shamrock

Also shown is a trimmed specially print panel

with rounded corners as optional top decor.

This is the Authentique brand specialty print panel.

2. Prepare each half of hull shape by bending back

on all perforations for panels and end tabs,

back lower edge joint flange tab of upper half.

Identify the back bottom hull edge with 

the split arrow symbol, which will be useful . . .

. . . when eventually joining the top to bottom

at back flap seam, simulated here.

3. Bend the hull walls back to position angled seam

where plain straight edge overlaps adjacent tab

perforation lines, and join seam. Repeat for all four

seams of both upper and lower hull halves.

4. Apply glue to backside of hinge flange on upper hull, 

then position over back upper edge of lower . . .

. . . adjust to be centered, then join seam.

Check on inside of hulls to make sure that the top

of bottom hull wall aligns with the perforation line.

5. To close the clamshell box, make sure that

the UPPER hull walls are directed inside the lower

hull raised side walls.

When upper hull is pushed fully down into position,

the side hooks should be able to slot into place

under the side end extensions.

Here is the closed box.

6. Prepare the medallion decor by positioning and

attaching the frame shape over the base shape,

centering, with tie holes aligned. Then position

and attach shamrock inside the frame's oval.

7. Tie knot and bow with narrow ribbon or twine,

then position and attach, centered, on box upper

hull panel.

8. As alternative, use specialty print paper panel,

trimmed out, or to size, then positioned and

attached to hull lid.
