In use the container may be filled iiush with the top of the neck portion 3, and the detachable guard member 17 has its frame 18 resting upon the latter withits attached transparent window sheet 19 guarding the contents against the touch of the prospective lifted the lid 31. After the purchase has been made the cap 7 may by unscrewing be removed, the member 17 be withdrawn and discarded to facilitate access to the user, and the cap be replaced by screwing it down until the sealing ring 14 rests upon the top of the jar neck.

By placing the screw thread 12 upon the lining ring 11 rather than forming the engaging thread upon the cap skirty the latter is undefaced and unweakened.
