About this mockup

A tuck box variant is a one-piece tuck end carton with an extra structural detail: a lid lock (thumb notch, slit lock, tongue into slot, tab lock), a zipper tear strip, an angled opening, a flip cover, a neck lock shelf or a hang tab. Still one die cut and one glue line, like a plain tuck box.

Usually holds
15–50 ml dropper serum bottles.

How to use this mockup

  1. Start from the 40 × 40 × 120 mm sample or type your own size.
  2. Design straight on its real dieline.
  3. Turn it in 3D, export a picture or video, or stage a scene.

Trade tips

  • Run the artwork 3 mm past the cut line and keep text 3 mm inside it.
  • Put the main design on the face the shopper sees first on the shelf, not on the lid.
  • Ivory board prints best on its coated face; keep the uncoated inside to one colour.
  • Matte lamination feels premium and softens colours by about a shade: add contrast in the design.

Questions

Is the serum box with neck lock mockup free?

Yes, commercial use included; Free adds a watermark grid at 1K, Pro exports 4K without it.

Can I use my own size for the serum box with neck lock?

Yes — from the 40 × 40 × 120 mm sample or your own size, with the dieline redrawn.

Can I get the serum box with neck lock dieline for printing?

Yes, with Pro: the die files (SVG, PDF / AI, DXF / CF2) and the CMYK print PDF; designing on the die is free.

What is the serum box with neck lock sample printed on?

The sample is ivory (C1S board) 300 gsm with matte lamination, on a dieline drawn at the size you type.

Construction

The body is still a four-panel tube closed by one side glue seam, with tuck ends top and bottom; what changes is the locking detail cut into the tuck, dust flaps or front panel — a thumb notch, slit-lock shoulders, a tongue-and-slot, a tab through a slit, a tear strip, a hang tab, a display board or a neck-holding insert. Each detail is only extra cuts, creases or holes on the same cutting die, so it adds no gluing step but makes the die more complex. The base can be a tuck, a 1-2-3 snap lock or a pre-glued auto-lock bottom depending on product weight.

Choosing board and material

Ivory board of 300–350 gsm is the default for medicine, cosmetics and small accessories; products over about 500 g, or boxes with tear strips and load-bearing locks, should move to 350–400 gsm or a tougher-fibred board such as SBS so lock teeth don't snap. Neck-lock inserts and double walls use roughly 20–40 % more board than a plain tuck box, so check sheet yield early. Open food boxes (bakery, produce, takeaway) need food-contact board or a greaseproof liner.

Finishing

Matt or gloss lamination keeps tabs, slots and tear strips from fraying after repeated opening; foil, embossing and spot UV sit on the front as on any tuck box. Keep foil and embossing off tear lines, lock slits and the creases of tabs — the board stiffens and tears off-line or cracks. A PET window belongs on a panel that carries no locking detail.

Preparing the print file

Design on the exact dieline of the variant, with cut, crease and perforation (tear) lines on separate named colours so the die maker reads them. Keep type and logos at least 3 mm from thumb notches, lock slits and hang holes; on panels crossed by a tear strip, plan the layout so mandatory information stays on the part that remains. Add 3 mm bleed and leave the glue flap clear if it is machine-glued.

Common mistakes

  • Barcode or expiry date on the part that gets torn off: once the strip is pulled, the batch can't be checked at the pharmacy.
  • Board too thin for a tab lock or tongue-and-slot: after a few openings the teeth snap or the slot rips and the lid springs open.
  • Resizing the box but keeping the hang hole or thumb notch position from the old file: the hole is off-centre and the pack hangs crooked.
  • Foil laid across a tear line: the board stiffens, the strip breaks halfway and the edge tears ragged.

Questions and answers

What is the neck holder in a serum box made of?

It's a panel folded from the same die, with a round hole gripping the neck of a 30 ml dropper bottle; no loose insert, so the bottle stands straight in the 40 × 40 × 120 mm box.

How large should the neck-lock hole be for a serum bottle?

Smaller than the shoulder and about 0.5–1 mm larger than the neck; measure the actual bottle batch, as glass necks vary by a few tenths of a millimetre between suppliers.

What is a thumb notch on a tuck box?

A half-moon cut on the front panel edge where the thumb lifts the tuck flap; the box is otherwise a standard tuck end, and the notch is one extra cut on the die, so it adds almost nothing to production.

How is a tear strip made on a paper box?

Usually two parallel perforated or zipper cuts made by the cutting die, with a pull tab at one end; some boxes add an applied tear tape for a cleaner pull. Tougher board gives a neater tear.

Do tab-lock tuck boxes need glue?

The body still has one side glue seam; tabs, tongue locks and C-locks only replace sealing the lid, so it stays shut without stickers or glue. Some variants are fully glueless, locking the side seam with a tab through a slit.
