The present invention relates to wallet packaging for dosage forms, such as dosage forms for medicaments, herbal extracts, vitamins, or the like.
Wallet packages for dosage forms have gained popularity as vehicles for delivering medicaments and the like to consumers. In these packages, blister packs in which dosage units can be pushed through a retaining barrier are adhered between layers of cardboard or the like. The dosage units can be viewed through holes in one of the sandwiching layers, with this layer typically having language that helps the user comply with dosage requirements, dosage schedule or the like. To access a dosage unit, it may be pushed through the back barrier and a corresponding hole in the other sandwiching layer. Other panels of cardboard allow the sandwiching layers to be folded into the wallet, and provide surfaces on which to provide promotional material, compliance information, safety information, or the like.
What has not been available is a cost-effective means to have the advantages of a wallet package along with child resistance. Efforts to provide such child resistance have typically involved making mechanical puzzles or other barriers involving the packaging around the blister sheet. For example, one device must be opened, a cardboard button engaged, and the working part of the wallet device slid out, as illustrated in
In one embodiment, the invention relates to a wallet package for presenting blister sheets comprising: (1) a first wallet panel with a width and height (without limitation as to shape); (2) a blister sheet comprising dosage forms enclosed between a first side material and a second side material, the second side material having one or more blister barriers, wherein the blister sheet is secured to the first wallet panel such that (i) the dosage forms and the corresponding area of the blister barrier(s) can nonetheless be pulled away from the first wallet panel, or (ii) an edge of the blister sheet can be pulled sufficiently away from the first wallet panel so that blister access devices for said blister barrier(s) can be accessed; and (3) additional wallet panels with a width and height hingably connected, among themselves and the first wallet panel, such that when folded to a fold position a resulting width and height of the folded wallet package is about the width and height of a largest said wallet panel, wherein the wallet package can be reversibly folded to the fold position to cover the blister sheet, and reversibly unfolded to uncover the blister sheet.
The wallet package can be arranged with blister sheets secured face down on a panel, or face up. The face down embodiments are illustrated first.
The blister sheet has one or more backing layers of sufficient strength that a dosage unit (i) cannot be conveniently pushed through the backing layer(s) without peeling off some or all of at least one of the backing layers or (ii) can only be pushed through with a force sufficient to provide child-resistance. For example, as exemplified in the cutaway of
The layers (of the backing layers) adapted to be peeled away are typically strong enough to not tear (except along perforations, cuts or other deliberate weakened structures) during the peeling process. These layers can be, for example, polymer-reinforced paper, polymer sheets, and the like.
The dual-arrowed arcs shown in
First and second reusable closures 17A and 17B allow the wallet device to be stably but releasably closed to enclose the back side of blister sheet 20.
Fold 1E yields the view of
The various panels of a wallet package can be used to provide printing with marketing, dosage, warnings, and the like. Booklets can be securely or releasably affixed to a panel. For example, a product insert, such as one required by a regulatory agency, can be so secured or affixed. Or, secured or affixed can be a booklet that provides compliance assistance, such as a generic calendar with checkoffs, or the like.
It will be recognized that a wide variety of layouts of dosage units can be used in a blister sheet in a wallet package of the invention.
For simplicity, a number of additional embodiments shall be illustrated in a 4-panel layout similar to that of wallet package 10, with at least the first fold previously illustrated (fold 1D) already made.
By pulling the dosage units away from panel 4, the child-resistant opening mechanism can be more readily accessed. For example, blister access devices (defined below) located along an outer edge (pulled away from panel 4) can be accessed and engaged more easily. If a scissors or the like are needed to initiate a tear, pulling away allows access for a cut, and for any subsequent tear. Or, perforations can allow individual dosage units (or sets of dosage units) to be torn off, as facilitated by pulling away form panel 4, and then the child-resistant opening mechanism can be operated.
Hinges, such as hinges 65 or 85, can be, for example, fold lines, where folding can be facilitated by methods known in the art, such as perforation along the fold line, compression along the fold line, heat with compression, pre-folding, or the like. The hinges can be designed to bias, to some extent, the blister pack tending to return to a flat aspect (ignoring the protrusions), so as to facilitate closing the wallet package.
Lines 104A and 104B are typically to the other side from the contact surface (here, on the right side). Italicized numbers 1 through 8 illustrate an optional order of usage for the dosage units. After dosage units 1-4 have been used, in some embodiments line 104B allows the used portion of the blister sheet to be torn away, to provide greater access to the barrier access devices for dosage units 5-8. It will be recognized that the same multiple rows, and tearing away used rows, can be used with butterfly designs such as found in
Shaded areas 108A, 108B, 108C, 108D, are optional areas under the blister sheet that are secured to panel 4 with reclosable glue seals.
Similar embodiments to those described above, but with the dosage units oriented upwards, are shown in
The following terms shall have, for the purposes of this application, the respective meanings set forth below.
The term “dosage form” includes any solid form that is sufficiently self-cohesive to be presented in a blister sheet, and includes an amount of a material for delivery to a subject (such as by ingestion, as a suppository, as a lozenge, as a mucosal adherent, or the like).
A “blister barrier” is a covering for one or more dosage units of which at least a portion must be peeled, torn, cut, or pushed through to allow a user of a dosage unit to conveniently, but in a child-resistant manner, access the dosage unit. Any blister barrier usable to provide child resistance in a blister sheet can be used in the invention. Child resistance is as recognized in the pharmaceutical industry (e.g., F1, F2, F3 levels of child resistance).
Blister Access Device
A “blister access device” is any device used in a child-resistant blister sheet. Blister access devices can include, for example, a pull tab, a pull tab access by tearing perforations to allow peeling to reveal the pull tab, notches to facilitate tearing, and the like.
A “wallet panel” is any panel made of a moderately stiff material allowing a wallet package to be reusably opened and closed over a useful lifetime. It will be recognized that, depending on dimension, the support provided by adhered components, and the like, that the stiffness required for making a useful wallet package can vary.
A “subject” is any animal, including a human, for which it may be appropriate to delivery a dosage form.

Any patent application to which this application claims priority is also incorporated by reference herein in the manner described above for publications and references.
While this invention has been described with an emphasis upon preferred embodiments, it will be obvious to those of ordinary skill in the art that variations in the preferred devices and methods may be used and that it is intended that the invention may be practiced otherwise than as specifically described herein. Accordingly, this invention includes all modifications encompassed within the spirit and scope of the invention as defined by the claims that follow.
