A protected glass container for cosmetic and like substances, has an inner glass jar and an outer plastic protective jacket, both said parts having coengaging top rim portions arranged to position and secure the parts together. The rim portion of the glass jar engages the sealing liner of a closure cap, which has screw threads engageable with cooperable threads on the rim portion of the plastic jacket. The jar and jacket have spaced-apart side and bottom walls, and the rim portion of the jar is subjected mainly to compressive forces which are non-destructive. Tightening of the closure cap tends to increase the interlock between the rim portions of the jar and jacket.

A double-walled container for cosmetic and like substances, comprising in combination: (a) a jar part constituted of substantially non-compressible material, having an annular side wall and a transverse bottom wall joined thereto, (b) said jar part having an annular top sealing rim portion and shoulder means on the outer annular side surface of said rim portion, (c) an outer jacket for and assembled to said jar part, constituted of yieldable material, said jacket having an annular side wall and a transverse bottom wall joined to said side wall, (d) said jacket having a top rim portion on said side wall, and having shoulder means on its inner side surface engageable and cooperable with the said shoulder means of the jar part, (e) said top rim portion of the jacket being fully exposed upwardly of the jacket and being uncovered when the jar part and jacket are assembled to each other, and said top rim portion of the jacket having sloped fastening means on its outer annular side surface for engagement by a closure cap, (f) a turnable closure cap having a sealing liner, (g) said sealing liner engaging the said annular top sealing rim portion of the jar part to seal closed the contents of the latter, and (h) said closure cap having sloped fastening means on its inner side surface, cooperable with the said sloped fastening means of said jacket to pull the closure cap closed when it is turned, and cooperable by a camming action with the sloped fastening means of said jacket to exert radially-inward pressures on the top rim portion of the latter, thereby to securely lock the rim portions of the non-compressible jar part and the yieldable jacket to each other in response to tightening of the closure cap by virtue of interaction of the said fastening means with each other in yielding and non-yielding relation respectively, whereby separation of the jacket from the jar part is minimized when the closure cap is closed.
