🫙 涵 contain + 盖 lid = a lid that covers and takes everything in
盖 — grass 艹 + 盍 (cover/lid)
Originally written 葢, this character combines the grass radical 艹 with 盍 ('to cover'), which itself shows a lid over a vessel. It first referred to a thatched grass cover or lid, then broadened to mean 'to cover' generally, and later extended to surnames and the conjunction 'thereupon'.
