Abstract
A blister pack includes a cavity sheet including at least one product blister and an access blister associated with each of the at least one product blister, and a child resistant backing coupled to the cavity sheet, the child resistant backing including a weakened pattern corresponding with each of the at least one product blister formed in the cavity sheet, wherein the access blister includes a generally V-indent member configured to initiate a separation of the weakened pattern. The V-indent member focuses forces to allowing easy access to the product blister by adults, including seniors, while maintaining child resistant standards.
Claims32
A blister pack comprising:
- a cavity sheet including at least one product blister and an access blister associated with each said product blister, each said access blister at least partially bounding a corresponding cavity;
- and
- a child resistant backing coupled to said cavity sheet, said child resistant backing including a weakened pattern formed in said child resistant backing corresponding with each said product blister;
- wherein each said access blister comprises a top member and a sidewall extending from said top member and encircling said corresponding cavity, said side wall comprising a V-indent member projecting into said corresponding cavity that includes a first leg member and a second leg member joining at an intersection location, the V-indent member being configured to initiate a separation of each said weakened pattern.

A child resistant pharmaceutical blister package comprising:
- a cavity sheet including at least one pharmaceutical blister configured to house a pharmaceutical and an access blister associated with each said pharmaceutical blister;
- and
- a child resistant backing coupled to said cavity sheet, said child resistant backing including a weakened pattern corresponding with each said pharmaceutical blister formed in said child resistant backing;
- wherein each said access blister comprises a V-indent member comprising a first leg member and a second leg member joining at an intersection location, an openly exposed notch being bounded between the said first leg member and said second leg member, at least a portion of said intersection location pushing a portion of said child resistant backing away from said cavity sheet when said access blister is pressed toward said child resistant backing.

A child resistant pharmaceutical blister package comprising:
- a cavity sheet including at least one pharmaceutical blister configured to house a pharmaceutical and an access blister associated with each said pharmaceutical blister thermoformed in said cavity sheet;
- and
- a child resistant backing coupled to said cavity sheet, said child resistant backing including a weakened pattern corresponding with each said pharmaceutical blister formed in said child resistant backing, each said weakened pattern including one of a perforation, a slot, or a score;
- wherein each said access blister includes a front member having a first end and a second end both disposed spaced apart from the pharmaceutical blister associated with the access blister, a first side member coupled to said first end of said front member, said first side member extending away from said front member and toward said associated pharmaceutical blister, a second side member coupled to said second end of said front member, said second side member extending away from said front member and toward said associated pharmaceutical blister, and a generally V-shaped member, said V-shaped member including a first leg member and a second leg member joining at an intersection location, each said access blister being configured to initiate a separation of each said weakened pattern.

A blister pack comprising:
- a cavity sheet including at least one product blister and an access blister associated with each said product blister;
- and
- a child resistant backing coupled to said cavity sheet, said child resistant backing including a weakened pattern formed in said child resistant backing corresponding with each said product blister;
- wherein each said access blister includes an indent member forming a focused point, said focused point pushing a portion of said child resistant backing away from said cavity sheet when its said access blister is pressed toward said child resistant backing.

A method for opening a blister pack, the method comprising:
- pressing on an access blister formed on a cavity sheet so that a focused point extending from the access blister penetrates through a lidding coupled to the cavity sheet and outwardly pushes a portion of a child resistant backing mounted over the lidding;
- pulling away the portion of the child resistant backing from the lidding so as to uncover a portion of the lidding that covers an opening to a product blister formed on the cavity sheet;
- and
- pressing on the product blister so that a pharmaceutical located within the product blister penetrates through the uncovered portion of the lidding.
