Definitions

  • the invention relates to a packaging system for packaging and dispensing articles, and more specifically to a packaging system that includes an improved lock and release mechanism for releasably locking an internal slide card in an outer sleeve.
  • a known packaging system for packaging blisters packs and/or other articles includes a slide card that is received in an outer sleeve.
  • a blister pack is secured, mounted, or integral to the slide card.
  • Such a packaging system is a convenient packaging format for certain pharmaceutical applications because the slide card can be repeatedly removed from and returned to the outer sleeve, for example, to dispense unit doses from a blister pack.
  • the packaging system is also child resistant in that the slide card can be retained within the outer sleeve by a locking mechanism and released from the outer sleeve by a release mechanism. Operation of the release mechanism in order to release the slide card from the outer sleeve requires a set of actions that are counter-intuitive to a child.
  • the locking mechanism of some packaging systems includes elements that are constructed from materials that may deform or lose their resiliency with repeated use. In such packaging systems the locking mechanism may not properly engage or can be disengaged to remove the slide card from the outer sleeve without properly operating the release mechanism, thereby inadvertently allowing access to the blister pack and/or other articles therein. Accordingly, there remains in the art a need for a packaging system that facilitates easy access to articles by the intended user and that has an improved locking mechanism so as to be less susceptible to manipulation by an unintended user, such as a child.
  • the present invention overcomes the deficiencies of the known art and the problems that remain unsolved, by providing a packaging system that includes an improved slide card which is received in an outer sleeve.
  • the improved slide card includes a support element that is disposed between a base panel and an engaging tab of the slide card as the engaging tab is folded along a hinge that connects the engaging tab and the base panel.
  • the engaging tab is an element of a locking mechanism for locking the slide card in the outer sleeve.
  • the support element maintains the structural integrity and the spring back capability of the hinge. Thereby, the slide card can be repeatedly inserted into and removed from the outer sleeve without compromising the functionality of the lock and release mechanism.
  • the packaging system includes elements that provide a locking mechanism for retaining the slide card within the outer sleeve as well as elements that provide a release mechanism for releasing the slide card from the locking feature.
  • the slide card can be repeatedly removed to dispense articles to an intended user and reinserted in the outer sleeve to prevent the articles from being dispensed to an unintended user.
  • the elements that provide the locking feature include an engaging tab of the slide card and an engaging aperture of the outer sleeve. The engaging edge of the engaging tab engages an edge of the engaging aperture to releasably lock the slide card in the outer sleeve.
  • the elements that provide the release mechanism include a release button of the outer sleeve that can be pressed to disengage the engaging edge of the engaging tab from the edge of the engaging aperture such that the slide card can be at least partially removed from the outer sleeve.
  • the engaging tab is hingedly connected to a base panel of the slide card.
  • the resiliency of the slide card ensures that the engaging tab tends to rotate away from the base panel such that the engaging edge of the engaging tab is forced into the engaging aperture. After repeated use and/or if the engaging tab is folded too far toward the base panel, the slide card can lose its resiliency such that the engaging edge of the engaging tab is not properly forced into the engaging aperture.
  • the exemplary slide card includes a support element that is secured to the engaging tab or the base panel.
  • the support element is dimensioned and positioned so as to be disposed between the base panel and the engaging tab when the engaging tab is folded toward the base panel.
  • the support element defines a minimum angle between the base panel and the engaging tab. This angle is determined such that the engaging tab is prevented from being folded too far toward the base panel, thereby retaining the resiliency of the slide card.
  • the support element and blister packs are secured to the slide card.
  • the exemplary support element includes a flanged portion and a support blister.
  • the support element can be formed by a process that is similar to that used to form the blister packs.
  • the support blister can be formed from sheet material as the blisters of the blister packs are formed from sheet material.
  • the support element is independent of the blister packs.
  • the support element can be integrally formed as part of a blister pack.
  • the slide card may be configured to hold articles on structures other than a blister pack, such as a tray as taught in one or more co-pending applications that claim priority to U.S. provisional patent application number 60/591 ,677, and incorporated herein by reference. Still other alternative embodiments include articles attached directly to the slide card, without first being placed in primary packaging.
  • the support element can be structure that functions to prevent the engaging tab from being folded toward the base panel such that there is at least a minimum angle between the engaging tab and the base panel.
  • the blank that forms the slide card can include panels that can be folded and secured to provide a support structure between the engaging tab and the base panel. A wedge, disc, series of pegs, or similar protruding object can be secured to the base panel and/or to the engaging tab to provide a support element.
  • the support element and the blister packs are secured to the slide card as the support blister and the blisters of the blister packs are received in apertures of a blank that forms the slide card and the flange portions of each are sandwiched between panels of the blank that forms the slide card.
  • the support element can be secured to the base panel and/or to the engaging tab by any suitable means for securing including, but not limited to, glue or other adhesives, mechanical fasteners, chemical bonding, VELCRO ® , tape, a combination thereof, and the like.
  • a support element is secured to the base panel and that support element contacts the engaging tab at a contact point.
  • a support element is secured to the engaging tab and that support element contacts the base panel at a contact point.
  • each of the engaging tab and base panel include one or more support elements that contact one another.

  • the invention is illustrated in the context of a package that includes a slide card that can be releasably locked in an outer sleeve.
  • the illustrated package can provide primary or secondary packaging for many different products and especially for products that require child-resistant packaging.
  • the present invention provides secondary packaging for blister packs that are secured to or integral to the slide card so as to be releasably locked in the outer sleeve.
  • a tray for receiving a product is integral to or directly attached to the slide card.
  • the slide card includes an engaging tab and a base panel that are hingedly connected to one another along a fold line.
  • the slide card further includes a support element that is disposed between the engaging tab and the base panel such that the resiliency of the slide card is not compromised, as described in further detail below.
  • an outer sleeve blank 10 for forming an outer sleeve 12, shown in FIGs. 2 and 5, is first described.
  • the outer sleeve blank 10 is formed from a foldable sheet material such as paperboard, corrugated board, plastic, cardboard, any other flexible and durable material, a combination thereof, and the like.
  • the selection of this material may be made according to the packaging needs. For example, a material selected for medicines should be recognized as safe by the Food and Drug Administration.
  • the material may be selected from a sheet of bleached sulfate board, a sheet of solid unbleached sulfate board (SUS), clay-coated newsback (CCNB), or any other suitable board material.
  • SUS solid unbleached sulfate board
  • CCNB clay-coated newsback
  • the paperboard may be clay coated on one side (C1S) or both sides (C2S) with a coating such as a fluidized blend of mineral pigments.
  • the mineral pigments may be coating clay, calcium carbonate, or titanium dioxide and may be combined with starch or adhesive. Successive densification and polishing (via calendering) finishes each coated surface to a high degree of smoothness and renders it suitable for printing graphics of superior quality.
  • Text or graphic information may be printed on the outer sleeve 12 or on the surface of a slide card according to any means conventionally known in the art.
  • a slide card blank as described herein can be formed from a foldable sheet material such as those described above.
  • At least a part of one or both sides of the blank 10 may be laminated with a polymer film.
  • the outer sleeve 12 is made more resistant to tearing.
  • this lamination may not extend over the entire surface of the blank 10 since only tear prone regions of the outer sleeve 12 may require lamination.
  • Suitable laminating materials may be selected from biaxiaily oriented or cross-laminated polymeric films such as high density polyethylene (HDPE), polyolefins, polyesters, or combinations thereof.
  • tear resistance may be provided at stress points, such as the corners and exposed edges of the outer sleeve 12, by applying one or more strips of polymeric film over these areas.
  • the polymeric film may be applied by extrusion, adhesive lamination, or by any other suitable means known in the art. Polymeric film is typically applied to the side that is the interior surface of the blank 10. Similar lamination with polymeric film may be used to treat the surface of a slide card.

  • the engaging edge 428 of the engaging tab 420 can be shaped as an arc, several arcs, a series of peaks and valleys, one or more pointed ends, combinations thereof, and the like.
  • the release button 90 and the node 88 cooperate such that, when a force F is applied to the release button 90, the release button 90 and the node 88 deflect into the outer sleeve 12 thereby pushing against the engaging tab 420 to release the engaging edge 428 from the edge E2 of the engaging aperture 86.
  • the slide card 400 may then be at least partially withdrawn from the outer sleeve 12.
  • the spring resistance of the engaging tab 420 holds the engaging edge 428 of the engaging tab 420 against the inner panel 20 such that the engaging edge 428 abuts an edge of, or otherwise the engaging tab 420 interlocks with, the inwardly folded extension panel 54 so as to prevent the slide card 400 from being fully removed from the outer sleeve 12.
  • the support element 312 can be positioned to provide a physical stopping point for the release button 90 and node 88 and to provide feedback to a user applying the force F that indicates that the release button 90 is fully depressed and the slide card 400 is able to be removed.

  • the engaging tab 420 is approximately at an angle X with respect to the base tab 422.
  • the engaging tab 420 can be held against or flexed over the support element 312. By restricting how far the engaging tab 420 can be folded along the fold line 430 toward the base panel 422, the hinged connection between the engaging tab 420 and the base panel 422 retains its resiliency.
  • the support element 312 can alternatively be positioned and dimensioned to provide a leverage point P about which the engaging tab 420 flexes as the force F is applied to the release button 90.
  • the engaging tab 420 can contact the support blister 354 of the support element 312 at or near the leverage point P as the engaging edge 428 of the engaging tab 420 is releasably engaged with the edge E2 of the engaging aperture 86.
  • the release button 90 contacts the engaging tab 420 at a point that is offset from (from the perspective of FIG. 7, to the right of) the leverage point P.
  • the leverage point P does not provide a stopping point for the push button 90 and the engaging tab 420 does not rotate or hinge about the fold line 430.
  • the relative positions of a first portion of the engaging tab 420, which is substantially defined between the point P and the fold line 430, and the base panel 422 are substantially fixed at an angle X.
  • the fold line 430 merely provides an attachment point between the engaging tab 420 and the base panel 422.
  • a second portion of the engaging tab 420 that is distal of the leverage point P flexes relative to the plane defined by the first portion about the fulcrum defined by the leverage point P.
  • the inherent rigidity and elasticity of the engaging tab 420 provides that the engaging tab 420 can return to the locking position, wherein the first and second portions of the engaging tab 420 are substantially aligned, and to repeatedly flex between a locking position and a release position.
  • the false end wall 102 enhances the structural integrity of the outer sleeve 12 by providing a brace between the top and bottom walls 224, 222 of the outer sleeve 12 and thereby allows the outer sleeve 12 to be more resistant to deformation from squeezing or crushing. Squeezing or crushing the outer sleeve 12 can inadvertently disengage the locking mechanism of the package, thereby providing inadvertent access to the items therein. As best illustrated in FIG.
  • the false end wall 102 obstructs an opening at one end of the tubular structure T to additionally prevent the articles in the package from being inadvertently accessed.
  • the edges of the apertures A1, A2 define notches at the open end of the outer sleeve 12 to facilitate removal of the slide card 400.
  • the aperture A1 is substantially centered with respect to inner panels 20 and the aperture A2 is off center with respect to the bottom panel 22.
  • the notch that is defined by aperture A1 aligns with the notch N1 when the panels 20, 24 overlap to form the outer sleeve 12 and the notch that is defined by the aperture A2 is offset from or is otherwise intentionally misaligned with the notch defined by the aperture A1 and with the notch N1 with respect to the perpendicular direction between the top and bottom walls 224, 222.
  • the offset relationship between the notches provides an additional child-resistance feature in that, to open the package, the user must grasp the slide card 400 at the positions defined by the offset notches.
  • Grasping the slide card 400 in this manner requires asymmetric placement of the fingers, which is counter-intuitive to children, and thus their ability to grasp and withdraw the slide card 400 from the outer sleeve 12 is greatly reduced.
  • the position of the apertures A1 , A2 as well as the position of the notch N1 can be varied such that the notches along the edges of the open end of outer sleeve 12 are offset from one another to produce the same relationship.
  • the location of the notches may be varied depending on the overall dimensions of the package.
  • the present invention offers advantages in that it is lightweight, tamper resistant, senior friendly, durable, easy to assemble, economical, and offers protection of the articles contained therein.
  • the invention provides a child resistant, yet user-friendly, unit dose packaging container that may be used to contain and dispense a variety of products.
  • the improved tamper resistant features of the package may be attributed, at least in part, to the presence of the false bottom structural support, the offset notch placement, and the use of partially or fully laminated structural materials in construction of the package sleeve and slide card.
