DETAILED DESCRIPTION OF THE INVENTION
Paperboard is used as a substrate for outer sleeve blank 2 (Figure 1) and inner slide card blank 100 (Figure 6) and is, typically, constructed from a sheet of bleached sulphate, solid unbleached sulphate (SUS) or clay-coated newsback (CCNB).
Definitively, the term paperboard describes paper within the thickness range of 0.2 to 0.7 mm (0.008 to 0.028 inches). The invention is relevant to the full scope of such a range, as applied to packaging and beyond.
When used for unit dose packaging stock, the paperboard is usually clay coated on at least one side surface and occasion-ally on both sides. The paperboard trade characterizes a paperboard web or sheet that has been clay coated on one side as C1S and C2S for a web coated on both sides. Compositionally, the paperboard coating is a fluidized blend of minerals such as coating clay, calcium carbonate and/or titanium dioxide with starch or adhesive which is smoothly applied to the traveling surface. Successive densification and polishing by calendaring finishes the mineral coated surface to a high degree of smoothness and superior graphic print surface.
With reference first to Figure 1, there is illustrated an advantageous environment for use of the concepts of this invention. In particular, outer sleeve paperboard blank 2 is illustrated. Blank 2 includes, in part, extension panels 4 and 8, conventional glue area 6, side panels 10, 18 and 26, cut away areas 12 and 14, node 16, side panels 20 and 24, cut outs 21 and 28, end flaps 22 and 32 and release button 30.
Cut away areas 12 and 14 and cut outs 21 and 28 are constructed by suitable cutting techniques. Release button 30 is cut within panel 26 by conventional techniques.
As shown in Figure 2, extension 9 is folded over and adhesively attached to panel extension 8 by conventional techniques.
With respect to Figure 3, extension panel 8 is folded over side panel 10.
As shown in Figure 4, side panel 10 is folded over side panel 18. Also, as can be seen in Figure 4, side panel 10 includes conventionally applied adhesive area 34.
As shown in Figure 5, there is illustrated a completely constructed outer sleeve 50 which includes release button 30 and panel extension 4. In this manner, panel extension 4 acts as a stopping device that prevents inner slide card 100 (Figure 9) from being pulled completely out of outer sleeve 50 (Figure 10).
In particular, as shown in Figure 8, folded panels 4 and 8 extend down towards side panel 18 to create the stopping device.
With respect to Figure 6, there is illustrated inner slide card paperboard blank 100. Blank 100 includes, in part, side panels 102 and 104, side panel extensions 106 and 108, conven-tional unit dose packaging holes 110, conventional unit dose packaging perforated areas 112, panels 114 and 116, side panels 118 and 120 and conventional unit doses 122. Also, it is to be understood that side panels 102, 104, 118 and 120, extensions 106 and 108, and panels 114 and 116 are constructed of the same material as side panel 10 (Figure 1).
In Figure 7, panels 102 and 118 have been folded over panels 104 and 120, respectively, such that unit doses 122 extend through holes 110 in panels 102 and 118 and unit doses 122 are trapped in holes 110.
As shown in Figure 8, extension panel 106 is folded over side panel 102.
As shown in Figure 9, side panel 118 is folded over side panel 102 along panel 114 to complete the structure of inner slide card 100.
As shown in Figure 10, inner slide card 100 is located within outer sleeve 50.
Package 150 also includes a locking feature, as previously discussed. The locking feature consists of release button 30, cut away 14, node 16 and extension panels 4 and 8. In this manner, after inner slide card 100 is placed within outer sleeve 50, extension 106 of inner sleeve 100, extends past opening 14 of outer sleeve 50 as shown in Figure 10. Once extension 106 is moved past opening 14, extension 106 springs up and enters into opening 14 and is biased against node 16.
Therefore, if the end user attempts to remove inner slide card 100 from outer sleeve 50, extension 106 slides up along opening 14 to prevent the removal of inner slide card 100 from outer sleeve 50. However, in order to deactivate the sliding movement of extension 106 along opening 14, the end user merely has to push release button 30 such that ex tension 106 is pushed against node 16 and below opening 14, thereby preventing extension 106 from sliding up through opening 14.
Finally, Figure 11 shows the retaining feature of package 150. After release button 30 has been pushed in order to allow the end user to pull inner slide card 100 from outer sleeve 50, extension 106 interacts with the upper end of sleeve 50 near cut away 28 such that extension 106 is caught and retained by folded over extensions 4 and 8 as shown in Figure 5 It is to be understood that the purpose of outer sleeve 50 ~s to house inner slide card 100. In addition, outer sleeve 50 has one or more release buttons 30 to release extension 106 from opening 14. Also, outer sleeve 50 can be formed using a number of conventional techniques that are standard to the folding carton industry. Finally, package 150 can be sealed by conventional techniques to simulate a tamper evident like presence.
It is also to be understood that the purpose of inner slide card 100 is to retain unit dose packaging within outer shell 50.
Inner slide card 100 allows the end user to gain access to the unit dose product 122 while pulling inner slide card 100 out until it stops, as shown in Figure II. Folded extensions 4 and 8 are used for, two functions in the present invention. First, folded extensions 4 and 8 and extensian 106 prevent slide card 100 from being completely removed outer shell 50. The second function is that extension 106 serves as a locking mechanism when the package 150 is in the closed position, as shown in Figure 10.
Once given the above disclosure, many other features, modifications or improvements will become apparent to the skilled artisan. Such features, modifications or improvements are, therefore, considered to be a part of this invention, the scope of which is to be determined by the following claims.

With respect to Figure 3, extension panel 8 is folded over side panel 10.
As shown in Figure 4, side panel 10 is folded over side panel 18. Also, as can be seen in Figure 4, side panel 10 includes conventionally applied adhesive area 34.
As shown in Figure 5, there is illustrated a completely constructed outer sleeve 50 which includes release button 30 and panel extension 4. In this manner, panel extension 4 acts as a stopping device that prevents inner slide card 100 (Figure 9) from being pulled completely out of outer sleeve 50 (Figure 10).
In particular, as shown in Figure 8, folded panels 4 and 8 extend down towards side panel 18 to create the stopping device.
With respect to Figure 6, there is illustrated inner slide card paperboard blank 100. Blank 100 includes, in part, side panels 102 and 104, side panel extensions 106 and 108, conven-tional unit dose packaging holes 110, conventional unit dose packaging perforated areas 112, panels 114 and 116, side panels 118 and 120 and conventional unit doses 122. Also, it is to be understood that side panels 102, 104, 118 and 120, extensions 106 and 108, and panels 114 and 116 are constructed of the same material as side panel 10 (Figure 1).
In Figure 7, panels 102 and 118 have been folded over panels 104 and 120, respectively, such that unit doses 122 extend through holes 110 in panels 102 and 118 and unit doses 122 are trapped in holes 110.
As shown in Figure 8, extension panel 106 is folded over side panel 102.
As shown in Figure 9, side panel 118 is folded over side panel 102 along panel 114 to complete the structure of inner slide card 100.
As shown in Figure 10, inner slide card 100 is located within outer sleeve 50.
