The diameter of orifice 350 may be selected to substantially match the width of pill 124. Generally, any dimension of orifice 350 (having any shape) may be selected to match any dimension of pill 124 without departing from the scope of the invention. In housing 300, since pill 124 and orifice 350 are of substantially similar dimensions, pill 124 may be pushed through second rigid layer 314 only when oriented and positioned to align with orifice 350. Therefore, such a mechanism may impede but not prevent the extraction of pill 124.
  • Barrier layer 316 includes tab 356 that are defined by perforation lines 352 on bottom surface 360 (FIG. 3D) of blister housing 300.

  • a user may grip and pull tab 356 by inserting a fingernail in slot 354 to release tab 356. The user may then pull tab 356 along perforation lines 352 to reveal the underlying orifice 350.
  • the user may first align pill 124 with a region near orifice 350 and applies pressure to collapsible receptacle 322 to cause it to collapse 322' and force pill 124 out. If aligned in proximity to orifice 350, pill 124 may be forced out by rupturing rupturable layer 336 and sliding pill 124 out through orifice 350 and blister housing 300.
  • second rigid layer 414 may be modified to include semi-circular opening 450.
  • opening 450 may be sized and shaped to align with a portion of collapsible receptacle 322.
  • a user attempting to extract pill 124 would have to move pill 124 by tilting entire blister housing 400 such that pill 124 lies above opening 450.
  • the user may then extract the pill by collapsing collapsible receptacle 322 to force pill 124 out through rupturable layer 336, second rigid layer 414 via opening 450, and barrier layer 316.
  • second rigid layer is configured with one or more cuts or incisions that bend away to allow pill 124 to pass out from blister pack 112.

Abstract

L'invention concerne des systèmes et des procédés relatifs à un système d'emballage comportant un emballage coque intercalé entre une pluralité de couches de protection. Une ou plusieurs couches de protection disposées au-dessus de l'emballage coque peuvent comprendre des perforations s'étendant le long de la zone périphérique. Un enfant essayant de séparer les couches de protection de l'emballage coque peut uniquement arracher la zone périphérique, rendant ainsi l'emballage coque sûr.
