Child Resistant Blister Packaging and a Method of Removing The Contents Therefrom

Abstract

A child resistant blister packaging having an upper cover sheet with at least one aperture, a bottom backing card with at least one scored exit port, and a blister laminate situated between the cover sheet and the backing card, the blister laminate includes at least one blister containing a cavity for receiving a pill and a foil layer adhered to the a bottom surface of the sheet. The blister protrudes through the aperture in the cover sheet and is arranged on a carrier tab that will not line up in registry with the scored exit port in the backing card. Upon the application of sufficient force, the blister can be moved to align the pill-receiving cavity with the scored exit port and the blister can be collapsed to force a medicament stored in the cavity through the foil layer and the scored exit port.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to blister packaging designed to distribute products such as pharmaceutical drugs and the method of removing the contents of such packaging. More particularly, the present invention relates to blister packaging designed to distribute pharmaceutical drugs that provide difficult access for a child. The present invention is ideally suited for use with pharmaceutical drugs, but may be used to distribute any product that may be contained within blister packaging.BACKGROUND OF THE INVENTION[0002]Individual packages for medicaments are well know in the art and are typically provided as physician samples, dose prescriptions, over-the-counter pharmaceuticals, and the like as is well known in the trade. Such packaging usually contains medicaments which may be harmful, if ingested by a young child.[0003]Accordingly, the problem associated with the use of such packages is the ease in which the packaging may be opened by small c...

AI Technical Summary

Benefits of technology

[0004]It has been found that a blister packaging particularly suited for packaging at least one medicament can be constructed in accordance with the present invention. In addition, the blister packaging of the present invention is resistant to being opened by children by increasing the difficulty of opening, while still being easily opened by adults.

[0006]It is, therefore, an important object of the present invention to provide a package construction of the type described which is child resistant while still being easily opened by adults.

[0007]It is yet another object of the present invention to provide a method of removing the contents from a child resistant blister packaging that is easily performed by adults, but difficult to accomplish by children.

[0008]It is a further object of the present invention to provide a packaging having a rigid cover sheet and backing card, and a blister having a lateral protrusion to enable a user to properly grip the packaging when attempting to remove the contents of the blister.

[0009]It is a further object of the present invention to provide a packaging having an aperture in the cover sheet to guide a blister protruding through the aperture along an arcuate path, and a resilient deformation neck to provide spring-like resistance to the movement of the blister.

[0012]It is a further object of the present invention to provide a package construction having the advantageous characteristics mentioned in the preceding paragraph, which is simpler in structure and more economical in manufacture, and staunch, durable and reliable to effectively protect the contents, resist unauthorized tampering, and otherwise accomplish its intended objects.

Problems solved by technology

Such packaging usually contains medicaments which may be harmful, if ingested by a young child.

Accordingly, the problem associated with the use of such packages is the ease in which the packaging may be opened by small children as a result of insufficient resistance.
