DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
In recent years, a great deal of effort has been directed toward providing packaging for pharmaceutical products which contain sufficient impediments to access to the packaged drugs to prevent children from easily opening the package. These "child-resistant" packages also should be able to provide easy access to the packaged drugs to adults who are able to follow the directions for opening the package.
A popular type of child-resistant package currently on the market is the so-called "peel-push" packaging in which tablets are contained in individual flexible blisters of a thermoplastic material and sealed by a rupturable foil material which is in turn covered by a protective layer. Access to the tablets is selectively obtained by peeling off the protective layer to expose a rupturable foil material and pushing the tablet through the rupturable material by pressing on the blister. Examples of this type of packaging are illustrated in FIG. 7 and in U.S. Pat. Nos. 3,912,082, 4,011,949, 4,125,190, 5,088,603, 5,172,812 and U.S. Reissue Pat. No. 29,705.
Another popular type of child-resistant package is illustrated in FIGS. 5 and 6. This packaging 10 is made up of a polyvinyl chloride blister layer 116 having a blister 114 provided therein, a thin foil layer 120, a polyester support layer 122 and a paper bottom layer 124. Perforated lines 104, 106 and 108 separate individual packages 10 from each other and tear slits 110 and 112 are provided in the packages to allow access to the contents of the packages. The packages 10 are generally formed into arrays 102 made up of two or more packages 10.
Although child-resistant packaging has proved to be successful over a period of time in being effective in the prevention of children gaining access to the packaged drug, in environments where children are not present, the child-proof features of the packaging can be undesirable. That is, in hospitals and homes containing only elderly people, ease of access to the packaged pharmaceutical is probably the most important consideration with respect to packaging. Therefore, there is a need for a drug packaging which can be converted from being child-resistant, in which certain prescribed steps must be performed in order to obtain access to the drug, to nonchild-resistant, wherein access to the packaged drug is easily obtained.
SUMMARY OF THE INVENTION
It is, therefore, an important object of the present invention to provide a drug package construction which enables the package to be converted from child-resistant to nonchild-resistant with a minimum amount of effort by the user.
It is a further object of the present invention to provide a drug packaging having child-resistant features which require that specific manipulative steps be performed in order to gain access to an individual dose of medicament and which also contains features which enables the drug packaging to be modified by the user such that easy access to the contents of the drug packaging is afforded.
The above and other objects of the present invention are accomplished by providing a novel blister foil package for containing a solid medicament. This package comprises a first, second, and a third sheet. The first and second sheets are laminated together and have a plurality of blisters for containing a medicament formed therebetween and aligned into rows composed of two or more blisters. The third sheet is laminated to the second sheet at a side opposite to the first sheet. A first access means is provided in the first, second and third sheets for enabling access to only an individual blister and a second access means is provided in the third sheet for providing access to a row of blisters.
