A child-resistant and senior-friendly unit dose package has a hollow container body and a tray with a plurality of items secured thereto for being dispensed from the container body. The container body has an end with an elongate opening defined by a rim, and the tray can be slid to a retracted position in which the tray is located within the container body and a dispensing position in which the tray extends at least partially through the opening of the container body. The package includes a separate cap removably securable to the container body to seal the opening and prevent access to the tray. Multiple simultaneous manipulations are required to remove the cap from the container body thereby providing a child-resistant connection.

The invention claimed is: 1. A unit dose package, comprising: a hollow plastic container body having an end with an elongate opening defined by a rim; a blister card having a plurality of separate blister compartments with a plurality of items separately secured therein for being dispensed from said container body, said elongate opening of said container body corresponding in size to an end profile of said blister card so that said blister card is slidable only in an end-to-end direction relative to said container body through said elongate opening between a retracted position in which said blister card is located within said container body and a dispensing position in which a part of said blister card extends through said opening of said container body; a plastic cap removably securable to said container body to seal said opening and prevent access to said blister card, said cap having an end wall with a spring captured to an underside thereof; and a locking mechanism for preventing a distal end of said blister card from passing through said elongate opening of said container body. 2. A package according to claim 1, wherein one of said container body and cap has a series of lugs and the other has a series of slots along which said lugs can travel when said cap is engaged to said container body. 3. A package according to claim 2, wherein said spring is retained in a position within said cap to apply a resilient force to cause said lugs to be retained in a captured position within said slots thereby preventing unwanted removal of said cap from said container body. 4. A package according to claim 3, wherein said cap has a peripheral sidewall extending from said underside of said end wall, wherein said lugs extend inwardly from said sidewall of said cap and capture said spring against said underside, and wherein said spring engages said rim of said container body when said cap is engaged therewith. 5. A package according to claim 4, wherein each of said slots is formed in an outer surface of a finish of said container body and has a reversely turned section and an open section, whereby removing said cap from said container body requires said cap to be pressed toward said container body against the force of said spring and slid laterally so that said lugs are permitted to exit said reversely turned sections and extend through said open sections. 6. A package according to claim 1, wherein said items are doses of medicines. 7. A package according to claim 1, wherein said elongate opening of said container body and said end wall of said cap are substantially rectangular. 8. A package according to claim 1, wherein said cap is formed of one-piece construction and is integral with said spring, and wherein an arm that pivots interconnects said cap to said spring. 9. A package according to claim 8, wherein said spring is an H-shaped leaf spring and is continuously bowed along its length. 10. A package according to claim 1, wherein said blister card includes a flat card portion having an upper face and a rear face, wherein said blister compartments project from said upper face, wherein said container body includes a spine extending within said hollow container body from a wall of said container body, and wherein said spine engages said upper face and forces said flat card portion against an opposite wall of said container body yet permits said blister card to slide relative to said container body. 11. A package according to claim 10, wherein said locking mechanism includes an end blister compartment on said distal end of said blister card and a post extending within said container body adjacent said elongate opening that prevents passage of said end blister compartment through said opening. 12. A container for doses of medicine, comprising: a hollow plastic container body having an open end with an elongate, substantially-rectangular rim and an opposite closed end, said container body being substantially rectangular in transverse cross-section; a substantially flat blister card carrying a plurality of doses of medicine within separate blister compartments projecting from an upper face of said blister card, said open end of said container body corresponding in size to an end profile of said blister card so that said blister card is slidable in only an end-to-end direction relative to said container body such that said blister card is positionable in a retracted position in which said blister card is located within said container body and a dispensing position in which said blister card extends at least partly through said open end of said container body; a plastic cap removably securable to said rim of said container body to seal said open end of said container body, said cap has a substantially-rectangular end wall and a peripheral sidewall extending from an underside of said end wall; a spring mounted on said underside of said end wall of said cap in a position to engage said rim of said container body when said cap is applied to said open end of said container body; and a locking mechanism preventing said blister card from undesired separation from said container body. 13. A package according to claim 12, wherein lugs extend inwardly from said sidewall of said cap and project within slots formed on an outer surface of said container body adjacent said rim when said cap is applied to said open end of said container body, and wherein said lugs capture said spring within said cap when said cap is removed from said container body. 14. A package according to claim 13, wherein said spring applies a resilient force to cause said lugs to be retained in a captured position within reversely turned sections of said slots when said cap is applied to said container body thereby preventing unwanted removal of said cap from said container body. 15. A package according to claim 14, wherein said slots have a substantially J-shaped or U-shaped configuration, whereby removing said cap from said container body requires said cap to be simultaneously pressed toward said container body against the force of said spring and slid laterally so that said lugs exit said slots through an opening at a top of the slot. 16. A package according to claim 14, wherein said cap is integral with said spring, is made of the same material as said spring, and is interconnected to said spring via an arm that pivots relative to said cap. 17. A package according to claim 14, wherein said spring is an H-shaped leaf spring and is continuously bowed along its length. 18. A package according to claim 14, wherein said container body includes a spine extending within said hollow container body from a wall of said container body, said spine engages said upper face of said blister card and urges said blister card against an opposite wall of said container body yet permits said blister card to slide relative to said container body. 19. A package according to claim 14, wherein said locking mechanism includes an end blister compartment on a distal end of said blister card and a post extending within said container body adjacent said open end of said container body that prevents passage of said end blister compartment through said open end.
