Abstract
A package includes a blank having a face panel and a back panel. The face panel includes apertures and face tabs. The back panel includes gates that correspond with apertures, and tab strips that overlap the gates and are adjoined to back tabs. A blister pack is sealed between the face panel and the back panel whereby blisters align over gates and protrude through apertures, and tabs and form a composite pull tab. To remove an item from a blister, the pull tab is pressed out of the panels, the tab strip is peeled from the back panel, and pressure is applied to force the item through the backing sheet of the blister pack and the exposed gate.
Claims14
A blank for forming a package for use with a blister pack, the blank comprising:
- a back panel comprising:
- at least one gate formed at a first face of the back panel, and through a partial depth of the back panel;
- and
- at least one tab strip located in an at least partially overlying stacked relation with the at least one gate, the at least one tab strip being removably formed at a second face of the back panel, and through a partial depth of the back panel, wherein the at least one tab strip is lifted away from the second face leaving a delaminated first configuration, leaving a corresponding delaminated second configuration that includes the at least one gate;
- and
- a face panel comprising:
- at least one blister aperture;
- and
- at least one removable face tab, the at least one removable face tab being at least partially severable from the face panel and corresponding to the at least one aperture;
- wherein
- when the first surface of the back panel and the face panel are placed in flat-face condition with respect to one another, the at least one aperture is at least partially aligned with the at least one gate;
- and a force is exerted upon the at least one removable face tab to urge the at least one tab strip away from the second face of the back panel.
A child-resistant blister package comprising:
- a blister pack comprising at least one blister and at least one corresponding blister opening;
- a back panel comprising:
- at least one gate corresponding to a respective at least one blister opening, the at least one gate being removably formed at a first face of the back panel, and through a partial depth of the back panel;
- and
- at least one tab strip, corresponding to the at least one gate, removably formed at a second face of back panel, and
- a face panel comprising:
- at least one blister aperture for receiving the respective at least one blister;
- and
- at least one removable face tab, the at least one removable face tab being at least partially severable from the face panel such that when a force is exerted upon the at least one removable face tab, the force at least partially severs the at least one removable face tab and urges the at least one tab strip at least partially away from the second face of the back panel;
- wherein
- the blister pack is placed between the face panel and the back panel in a stacked relation during assembly of the child-resistant blister package.
A method of forming a child-resistant package, the method comprising:
- providing a blister pack, a back panel, and a front panel, wherein:
- the blister pack comprises at least one blister and at least one blister opening;
- the back panel comprises:
- at least one gate, the at least one gate corresponding to at least one blister opening, and the at least one gate is formed at a first face of the back panel, and through a partial depth of the back panel;
- at least one removable back tab formed in the back panel;
- and
- at least one tab strip corresponding to and attached to the at least one removable back tab, the at least one tab strip being removably formed at a second face of the back panel and formed through a partial depth of the back panel,
- wherein:
- when the at least one tab strip is lifted away from the second face, the at least one tab strip delaminates the back panel leaving at least a portion of the second face intact, the portion of the second face comprising at least a portion of the at least one gate;
- and
- the face panel comprises:
- at least one aperture for receiving at least one blister, and
- at least one region corresponding to the at least one aperture defining a region at which a force may be exerted at the face panel to urge the at least one tab strip away from the second face of the back panel;
- and
- affixing the blister pack between the back panel and the face panel.
