  • top and backing layers may be formed of flexible packaging materials, rigid thermoformable plastic materials, foil, paper, laminates, or combinations thereof. Medicament cavities formed between such layers have been accessed by tearing into them from an edge of the package, which tearing may or may not be facilitated through the provision of a starting notch or slit.
  • these cavities may be accessed by stripping a backing layer from the package to expose the cavity, or to expose a push-through underlayer.

  • these packages are tamper evident, but typically not child resistant.
  • Other medication packages require some form of peeling of the bottom surface from the top surface to get access to the medication.
  • Child resistant medication packages that use peeling have been in use for some time, however, many people who do not have sufficient motor skills or whose hands shake are not able to easily gain access to the medicament is such packages. This can be a problem especially when the medicament and the medication packages are small. Additionally, there have been a number of medication packages that are designed to be torn open to access the medication. Many medication packages that are designed to be torn suffer from the same problems as those designed for peeling, namely they are difficult to open for those with reduced motor skills or do not exhibit a high degree of child- resistance.

Therefore, to open the child-resistant blister package (10) a user must: (i) apply a force to the base layer tab creation area (150) and the blister layer tab creation area (250) to cause separation of the base layer (100) at the base layer tab creation separation line (140) and the blister layer (200) at the blister layer tab creation separation line (240) such that a tab (300), having a base layer component (310) and a blister layer component (320), is created, as seen in FIGS. 9 and 11,

  • the separation lines (140, 240) are a substantially concave shape that opens away from the article receiving blister (260), as seen in FIGS.
  • Such a configuration cooperates with the natural tendency of a user to grip the blister package (10) between the thumb and forefinger from the end opposite the location of the medicament, or article receiving blister (260), as seen in FIG. 8. Gripping the blister package (10) in this fashion permits the user to simply roll the thumb, or forefinger, into either tab creation area (150, 250), while exerting a force on the area (150, 250), such that the separation lines (140, 240) allow the release of the tab (300) for subsequent manipulation.

  • the separation lines (140, 240) are slits that cut all the way through the associated layer (100, 200) because the use of multiple sections (142 and 144, 242 and 244) creates a tab retention projection (330), illustrated in FIGS. 10, 18, and 19, that prevents the unintentional creation of a tab (300).
  • the tab retention projection (330) acts to connect the tab creation area (150, 250) with the remaining body of the layer (100, 200).
  • the tab (300) could be created by the application of a minimal amount of force to either tab creation area (150, 250), and potentially by accident.
  • the tab retention projection (330) prevents such tab (300) formation and permits the blister package (10) manufacturer to determine the amount of force necessary to allow for the creation of the tab (300).
  • One such way of setting the amount of force necessary to create the tab (300) is by altering the magnitude of the separation line separation distance (146, 246).
  • the magnitude of the separation line separation distance (146, 246) is generally between 1/128 of an inch (0.198mm) and 1/8 of an inch (3.175mm), depending on the desired level of child-resistance.

  • a further variation of this embodiment is one in which the base layer tab creation separation line (140) is a slit extending through the base layer (100) from the base layer exterior surface (120) to the base layer interior surface (130), the blister layer tab creation separation line (240) is a slit extending through the blister layer (200) from the blister layer exterior surface (220) to the blister layer interior surface (230), and further including a tab retention projection (330) connecting the base layer tab creation area (150) and the blister layer tab creation area (250) to the main body of the blister package (10) thereby preventing the tab (300) from unintentionally leaving the plane of the base layer (100).
  • the blister layer (200), and more particularly the blister layer exterior surface (220), within the blister layer tab creation area (250), projects away from the plane of the base layer (100) thereby providing a user an indication of the location upon which to exert the force necessary to create the tab (300), as illustrated best in FIGS. 4, 6, and 7.
  • Such a projection allows a user to quickly identify, both visually and tactilely, the area upon which to apply a force to reveal the tab (300).

  • a sheet of suitable material for the blister layer (200) is exposed to heating elements for a pre-determined time. This sheet is then trapped in a forming station where it is subjected to both vacuum and pressure.

  • the base layer (100) may be comprised of one or more separate layers of material, such as foil and polyester or other suitable child-resistant foils.
  • the base layer (100) is typically comprised of multiple layers, but it could be made of any material deemed child-resistant. Additionally, the child-resistance is further increased by the fact that the previously disclosed method of joining the base layer (100) to the blister layer (200) ensures that peeling, or separation, of the layers (100, 200) from one another by human lingers is extremely difficult, if not impossible.
  • FIG. 20 Another preferred embodiment of the present invention is a medication package (600), illustrated in FIG. 20, comprising a plurality of separable blister packages (10) like those described above.
  • These separable blister packages (10) have their base layer (100) and/or blister layer (200) formed from one integral base layer (100) and one integral blister layer (200) with tear lines (610) on the base layer (100) and the blister layer (200) to enable the separation of the individual blister packages (10) from each other.
  • tear lines (610) may be perforations, score lines, slits, indentations, and/or weakened fracture lines.
  • the child-resistant blister package of the present invention answers a number of long felt needs in the medical community.

Abstract

L'invention concerne une plaquette alvéolaire destinée à contenir un médicament et comprenant une couche de base et une couche alvéolaire jointes ensemble. Chaque couche comporte une ligne de séparation d'obtention de languette permettant à un utilisateur de commencer une séquence prédéterminée d'étapes requises pour accéder au médicament. Les lignes de séparation d'obtention de languette sont situées à l'intérieur du périmètre de chaque couche associée. Ces lignes de séparation d'obtention de languette réduisent sélectivement la résistance de la couche associée, ce qui permet à un utilisateur de 'découper' ou d'obtenir une languette en vue d'un accès au médicament. Une pluralité de manipulations prédéterminées doivent être réalisées pour accéder au médicament. Ces manipulations consistent à appliquer une force permettant d'obtenir une languette, à arracher cette languette, d'où la formation d'une ailette sinistrorsum et d'une ailette dextrorsum, et à faire tourner l'ailette sinistrorsum et l'ailette dextrorsum dans des sens opposés de façon à provoquer une déchirure mettant à nu le médicament.
