A jar cap (12) is formed with an orifice (16) through its top surface and an adhesive (A) coated closure tab (18) is placed over the orifice (16). The closure tab (18) has a non-adhesive portion (20) for being grasped. The jar (10) is closed with the cap (12) and vacuum sealed. When the cap (12) is to be removed, the non-adhesive portion (20) of the closure tab (18) is grasped and the closure tab (18) is pulled off the orifice (16), allowing ambient air to enter the jar (10) and relieve the vacuum so as to make the removal of the cap (12) easier.
