My solution: A small lighter case made of PET plastic (from a recyclable PET bottle) and some duct tape.

Don't know if it's really worth the effort or not. For every day use I'd say just carry two. But for lighters that reside in kits it makes sense to have a little extra effort to prevent the lever to be pressed down and empty the lighter.

(I regard the safety hazard of BICs as infitesimal small)
