- a) an outer sleeve including a plurality of side panels, a plurality of hinge panels, said side panels and hinge panels being operatively connected to each other;
- and wherein at least one side panel includes a foldable extension thereof, said extension being folded toward the interior of the sleeve to form a false bottom;
- and further
- wherein one of the side panels includes an internal slide card retaining element and a first inner slide card releasing element, and another of said plurality of side panels includes a second inner slide card releasing element;
- wherein the outer sleeve includes a pair of offset notches for grasping and removing an internal slide card;
- wherein the outer sleeve is at least partially laminated with a polymeric film material;
- and
- b) an internal slide card having encapsulated therein one or more blisters each containing a unit dose of a material to be dispensed, the slide card being comprised of a slide card body and an extension, the extension being folded inwardly over and being positioned parallel to the slide card body when the package is closed.
A method of packaging unit dose materials comprising:
- a) cutting a blank for forming an outer sleeve from a substrate material;
- b) forming an internal slide card from a substrate material, said internal slide card including a body and a foldable extension thereof;
- c) folding the blank to form an outer sleeve including top and bottom panels and side panels, the side panels having included therein at least one slide retaining element and at least one slide releasing element, at least one side panel thereof comprising a foldable extension which, when folded, forms a false bottom within the interior of the sleeve;
- the blank further including a pair of notches positioned in an offset parallel relationship to each other when the blank is folded;
- d) encapsulating unit doses of a material onto the internal slide card;
- e) folding the extension of the internal slide card to position it parallel to the body of the slide card;
- f) inserting the folded internal slide card into the sleeve such that the extension thereof becomes slidably and lockably engaged with the slide retaining element in the side panels of the sleeve.
A blank for forming a lockable outer sleeve for housing an internal slide card of a unit dose package comprising a plurality of side panels and a plurality of hinge panels;
- at least one of said side panels comprising an extension thereof forming an internal slide card retaining element, and at least one side panel thereof additionally comprising a first internal slide card releasing element;
- and at least another side panel comprising a second internal slide card releasing element;
