A primary storage (2) container has a body portion (4), a neck portion (6) extending from the body portion, the neck portion providing an outlet of the primary storage container, an annular fitting (10) on the neck portion for fitting a closure (12) onto the primary storage container and at least one cutting element (14) extending outwardly of the fitting in a direction away from the outlet (8); and wherein the fitting has a first bayonet coupling (42) for releasably locking into the fitting a flange (36) forming a second bayonet coupling (44). A refill container (32) has a chamber portion (34), filled with a dose of a refill composition, the chamber portion having an annular flange defining (36) an opening (38) of the chamber portion (34), and a frangible film (40) covering the opening and attached to the annular flange (36), wherein the flange (36) has a male bayonet coupling (44). The primary storage container and the refill container (32) are combined in a packaging system.

1. A packaging system comprising: a) a primary storage container having a body portion of a first volume, a neck portion extending from the body portion, the neck portion providing an outlet of the primary storage container, an annular fitting on the neck portion for fitting a closure onto the primary storage container and at least one cutting element extending outwardly of the fitting in a direction away from the outlet; andb) a secondary refill container having a chamber portion, having a second volume smaller than the first volume, filled with a dose of a refill composition, the chamber portion having an annular flange defining an opening of the chamber portion, and a frangible film covering the opening and attached to the annular flange, wherein the fitting and the flange have complementary respective first and second bayonet couplings which are adapted releasably to lock the flange into the fitting to fit the secondary refill container over the outlet of the primary storage container, and the at least one cutting element is located to cut the frangible film when the first and second bayonet couplings are coupled together. 2. The packaging system of claim 1 wherein the first and second bayonet couplings each comprise a pair of opposed bayonet elements. 3. The packaging system of claim 1 wherein the fitting has a female bayonet coupling and the flange has a male bayonet coupling. 4. The packaging system of claim 3 wherein the male bayonet coupling comprises a plurality of flange tabs. 5. The packaging system of claim 4 wherein the secondary refill container is provided in an assembly of plural secondary refill containers, with at least some adjacent containers of the assembly being temporarily interconnected by respective adjacent flange tabs having a line of weakening therebetween. 6. The packaging system of claim 5 wherein the secondary refill container is composed of a thermoformed polymer. 7. The packaging system of claim 1 wherein the secondary refill container is composed of polyethylene, polypropylene or polyethylene terephthalate, or any one or more of these polymers in a monolayer or in a multi-layer laminate, optionally with a barrier resin layer. 8. The packaging system of claim 1 wherein the frangible film is compressible and comprises a gasket or the secondary refill container further comprises a gasket member around the annular flange. 9. The packaging system of claim 1 wherein the refill composition in the secondary refill container comprises a concentrated liquid hand soap composition. 10. The packaging system of claim 1 wherein the fitting is attached to the neck portion and wherein the at least one cutting element comprises a plurality of blade elements around the outlet and extending upwardly along an edge of the outlet. 11. The packaging system of claim 1 wherein the fitting includes a sealing surface at least partially surrounding the outlet for engaging an end surface of the secondary refill container when the secondary refill container is fitted as a closure over the outlet of the primary storage container, a locking surface spaced from the sealing surface and a gap therebetween for receiving the flange. 12. The packaging system of claim 1, wherein the first bayonet coupling in the fitting includes openings in the locking surface for receiving the second bayonet coupling in the form of bayonet tabs of the flange. 13. The packaging system of claim 1 wherein a plurality of support members is integrally molded to form an upper bearing surface for a portion of the flange when the secondary refill container is fitted as a closure over the outlet of the primary storage container. 14. The packaging system of claim 1 wherein the fitting further comprises a hinged lid for selectively closing the opening in the absence of the secondary refill container. 15. The packaging system of claim 1, wherein the primary storage container has a further outlet and closure assembly at a location remote from the fitting, and wherein the further outlet and closure assembly is at a lower end of the primary storage container and the neck portion, the annular fitting and the at least one cutting element are at an upper end of the primary storage container. 16. The packaging system of claim 1 wherein the primary storage container has at least two neck portions extending from the body portion, each neck portion providing a respective outlet of the primary storage container, each neck portion having a respective annular fitting thereon for fitting a respective closure onto the primary storage container, and each fitting having at least one cutting element extending outwardly thereof in a direction away from the respective outlet; and the packaging system comprising at least two of the secondary refill containers. 17. The packaging system of claim 1 wherein each fitting has a respective color corresponding to a color of a respective secondary refill container. 18. The packaging system of claim 1 wherein the primary storage container has a central longitudinal axis, the neck portion is substantially aligned with the central longitudinal axis, and the body portion has a first base support surface opposite to the neck portion. 19. The packaging system of claim 11 wherein the first base support surface is substantially orthogonal to the central longitudinal axis. 20. The packaging system of claim 1 wherein the at least one cutting element is located to cut at least one arcuate cut through the frangible film when the first and second bayonet couplings are mutually rotated during coupling together.
