Lost the button or ring on your Mepal Campus lunchbox? Replace either part quickly with genuine spare parts. No tools needed.
Quick answer
If the button or sealing ring on your Mepal Campus lunchbox is lost or damaged, you can order a genuine replacement part and snap it on in under a minute. No tools needed.
Which part do you need?
The Campus lunchbox uses two separate replaceable components: the closure button and the white sealing ring. The button is the part you press to open the lid; the ring sits around the lid edge and helps keep the box closed. They are sold individually, so you only replace what's missing.
If your lunchbox was made from 2018 onward (the version with a bento tray inside), the button is compatible with all those models. The ring fits any Campus lunchbox, but note that it is sold without the clip.
What you'll need
Just the replacement part itself. No screwdrivers, glue, or special skills are required. Both the button and the ring snap into place by hand.
Step-by-step replacement guide
- 1. Remove the old part: If the old button or ring is still attached, gently pry it off with your fingers. The button unclips from the lid; the ring peels away from the edge. No force needed. Do not use a knife or screwdriver — you may scratch the plastic.
- 2. Align the replacement part: Hold the new button or ring in the correct orientation. The button has a flat side that faces the lid hinge; the ring has a groove that fits over the lid rim. Check that the ring's groove is facing downward before pressing it on.
- 3. Snap it into place: Press firmly along the edges until you hear a click. For the button, press the center until it locks. For the ring, work your way around the rim, pressing evenly. If it doesn't click, remove and realign — never force it.
- 4. Test the closure: Close the lunchbox and press the button to open it. The lid should stay shut when carried and release smoothly when you press the button. If the lid feels loose, the ring may not be seated fully. Remove and reinstall.
