AI Technical Summary

Benefits of technology

[0015] It is yet another object of the present invention to provide an improved, inexpensive, child resistant blister package for medicaments.

Problems solved by technology

While such packages have provided efficient and effective packaging of individual dosages of medicament in tablet form, such packages are not child proof or child resistant, and present a potential hazard to small children.

While the known child resistant blister packages have been effective, at least to some degree, in preventing access to the packaged medicament by young children, they have not been entirely satisfactory for a number of reasons.

For example, some of the packages, while being child resistant initially, do not retain the desired degree of child resistance after a portion of the product has been dispensed.

Also, product packages in some of the child resistant packages have not been as readily accessible to adults as desired, particularly those with loss of manual dexterity.

Further, some of the known packages have been relatively expensive to manufacture and / or assemble.

Further, the pack does not permit access by children to the enclosed unit dosage forms even when part of the package has been dispensed (i.e. some of the dosage forms have been accessed by an adult).
