Push and peel pack for dispensing medicants

Abstract

A push and peel child resistant and senior friendly tamper evident package comprising a blister sheet with U cuts for pushing an outer layer of interior tabs, the blister sheet having blister pockets projecting from a front side thereof, a rupturable foil layer being adhered to the blister layer and reinforcing the paperboard material adhered to the foil layer, an inner data layer with diecut oval holes, the paperboard layer having a tear strip formed therein, the tear strip being defined by a cut into the paperboard layer from the side thereof adhered to the foil layer, the cut extending only a certain percentage of the total thickness of the paperboard such that a controlled delamination of the paperboard layer occurs when the tear strip is removed. This provides a precise reinforcement of the foil layer.

Claims

1. A child resistant and senior friendly tamper evident package, the package comprising: a blister sheet having at least one blister pocket projecting from a front side thereof;a rupturable foil layer sealed to a back side of the blister sheet to form a continuous cover over the blister pocket, the foil layer having a thickness and being formed of a material which can be ruptured to provide access to the pocket;a reinforcing layer of a paperboard material, said reinforcing layer having a first side with at least portions thereof adhered to the foil layer;a tear strip formed in said reinforcing layer, said tear strip overlying said at least one blister pocket;a tab formed at one end of said tear strip, said tab being non adhered to said foil layer; anda data layer overlying said blister sheet on said front side thereof, said data layer having at least one diecut portion formed therein, said at least one diecut portion being in registry with said tab such that pressure on said at least one diecut portion will permit said tab member to be lifted and said tear strip removed.

2. The package of claim 1 further including a paper layer secured to said rupturable foil layer under said paperboard material, said paperboard layer being adhered to said paper layer outside of said tear strips such that upon said removal of said tear strips access may be had to said foil layer and paper layer.

3. The package of claim 1 further including at least one line of weakening formed in said paperboard layer extending inwardly from said first side of the paperboard, said at least one line of weakening being located in a portion overlying the blister pocket, said at least one line of weakening extending into said paperboard for only a portion of the thickness of said paperboard.

4. The package of claim 1 wherein said tear strip is defined by a line of weakening extending thereabout, said tear strip line of weakening extending into said paperboard from a second side thereof for a distance of between 60% and 80% of the thickness of said paperboard.

5. A child resistant and senior friendly tamper evident package, the package comprising: a blister sheet having at least one blister pocket projecting from a front side thereof;a rupturable foil layer sealed to a back side of the blister sheet to form a continuous cover over the blister pocket, the foil layer having a thickness and being formed of a material which can be ruptured to provide access to the blister pocket;a reinforcing layer of a paperboard material, said reinforcing layer having a first side with at least portions thereof adhered to said foil layer;said paperboard layer having a tear strip formed therein, a tab member being located at one end of said tear strip;a data layer overlying said front side of said blister sheet;at least one diecut portion formed in said front data layer, said blister layer having a diecut formed therein, both said diecut portion and said diecut formed in said blister sheet being in registry with said tab member such that pressure applied on said diecut portion will cause said tab member to lift and permit removal of said tear strip.

6. The package of claim 5 further including a paper layer secured to said rupturable foil under said paperboard material, said paperboard layer being adhered to said paper layer outside of said tear strips such that upon said removal of said tear strips, access may be had to said foil layer and paper layer.

7. The package of claim 5 further including at least one line of weakening formed in said paperboard layer extending inwardly from said first side of said paperboard, said at least one line of weakening being located in a portion overlying said blister pocket, said at least one line of weakening extending into said paperboard for only a portion of the thickness of the paperboard.

8. A child resistant and senior friendly tamper evident package, the package comprising: a blister sheet having a plurality of blister pockets projecting from a front side thereof, said blister pockets forming at least three rows;rupturable foil layers sealed to a back side of said blister sheet to form a continuous cover over said blister pockets, the foil layer having a thickness and being formed of a material which can be ruptured to provide access to said pocket;a reinforcing layer of paperboard material, said reinforcing layer having a first side with at least portions thereof adhered to the foil layer;a plurality of tear strips formed in said reinforcing layer, each of said tear strips being associated with and overlying a single blister pocket;a tab formed at one end of each of said tear strips, each of said tabs being non adhered to said foil layer; anda data layer overlying said blister sheet on said front side thereof, said data layer having diecut portions formed therein, each of said diecut portions being in registry with one of said tabs, at least one inner row having a diecut formed in said blister sheet, both said diecut portions in said front data layer and said diecut in said blister sheet being in registry with said tab member such that pressure applied on said diecut portion will allow said tab member to lift and permit removal of a tear strip.
