Abstract
An exemplary blister package includes a blank having a face panel with blister and finger apertures, a center panel with gates and finger tabs, and a back panel with pull tabs and tear strips. A blister pack is positioned between the face panel and center panel so that each blister is positioned within a respective blister aperture. During assembly, the center and back panels are folded such that each gate and tear strip aligns with a respective blister, and each pull tab and finger tab aligns with a respective finger aperture. The respective panels and elements are bonded except for the tear strips and gates. To remove an item from a blister, the pull tab is pressed out of the panel, the tear 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.
Description
- This application claims benefit of U.S. Provisional Application No. 60/717,129 filed Sep. 14, 2005, the entirety of which is herein incorporated by reference.
- The present invention relates to apparatus and methods of packaging and dispensing items, and more specifically, the present invention is directed to a child-resistant package including a blister pack for dispensing items.
- It is well known to use blister packaging to store and deliver items. Such items may include pharmaceutical tablets, pills, and capsules. Conventional blister packages include a blister tray that is typically a thermo-formed plastic sheet having a plurality of blister cells or depressions formed therein. Typically, after the items are placed in the cells, the items are retained and protected in the respective cells by securing a backing sheet comprising foil, plastic, or paperboard to the back of the tray to seal the cells. In other types of conventional blister packages the contents are placed in substantially puncture proof foil containers that are then covered with foil or paperboard backing.
- In conventional blister packages, the foil backing is thin enough to be either punctured mechanically or ruptured by pressing the blister so that the enclosed item penetrates the foil. Typically with paperboard backing, gates are provided in the backing panel that covers the opening of the blister cells. In practice, each gate is deformed or manipulated so that it ruptures or partially separates from the surrounding paperboard, allowing the item within the blister cell to be pushed through the gate.
- While the conventional blister packages are suitable for some applications, there are several design deficiencies. The conventional blister packages provide removal of the items from the blister cells, but offer very little child resistance. Child resistance is a feature that is particularly desired for unit dose pharmaceutical packaging, and is mandated by the Poison Prevention Packaging Act of 1970. Guidelines are prescribed for packaging to satisfy the criteria for child resistance. For example, a child-resistance (CR) rating of F=1 requires that a random sampling of the subject packages not be compromised by an age-specific test pool of children at no greater than a predetermined failure rate. This general guideline is designed to ensure that the package has sufficient integrity against tampering by children.
- In addition to a blister package being child-resistant, it is also desirable that the package be senior friendly, that is, the package permits easy withdrawal of items from the package by an intended user requiring minimum manipulation even where a user's manual dexterity and strength is reduced. Accordingly, there remains in the art a need for apparatus and methods of blister packaging and dispensing items where child resistance is significant and can be easily increased, while the package remains senior friendly.
- The present invention overcomes the deficiencies of the known art and the problems that remain unsolved by providing a child-resistant package that is inexpensive, easy to fabricate, and can be used with conventional blister packs. Generally speaking, one embodiment of the child-resistant package includes a blister pack that is disposed and sealed between three panels. The package includes at least one tab strip and pull tab formed from a first panel, where the tab strip covers a gate formed on a second panel. The gate correspondingly aligns with a blister of a blister pack to additionally secure at least one item within the blister. In some embodiments, adhesive, placed between the tab strip and gate during assembly of the package substantially prevents the tab strip from attaching to the gate.
- In operation, pressure is applied to the pull tab to bend the pull tab out of the plane of the surrounding panel. The pull tab is pulled to break the tab strip from the surrounding panel and expose the gate. Finally, pressure is applied to the corresponding blister to force the enclosed item to rupture the backing sheet of the blister pack and to dislodge the gate, thereby gaining access to the item. The child-resistant value of the present invention includes security features that require a sequence of coordinated motions including pressing, pulling, and pressing again to gain access to an item.
- More specifically, in one embodiment a blank for forming a package for use with a blister pack comprises a first panel, which includes a blister aperture and means for identifying an underlying finger tab, a second panel which includes at least one gate defined at least in part by a severance line and at least one finger tab defined at least in part by a severance line, and a third panel which includes at least one tab strip having a pull tab and a tear strip. Here, the panels are arranged such that the blister aperture, gate, and tear strip are operationally aligned, and the means for identifying an underlying finger tab, the finger tab, and the pull tab are operationally aligned. In another embodiment, a blank for forming a package for use with a blister pack comprises a first panel including at least one gate defined at least in part by a severance line and means for identifying an underlying pull tab, and a second panel including at least one tab strip having a pull tab and a tear strip. Here, the pull tab is removable and the tear strip is at least partially removable from the second panel, and the means for adhesion is positioned such that the gate and tear strip are not substantially connected. Further, the panels are secured to each other such that the gate and tear strip are operationally aligned, and the means for identifying an underlying pull tab and the pull tab are operationally aligned. In a different embodiment, a package comprises a first panel including blister apertures and means for identifying an underlying finger tab, a second panel includes gates and finger tabs defined at least in part by severance lines; and a third panel including tab strips having pull tabs and a tear strips. Here, a blister pack having blisters holding items are positioned such that the blisters extend through the blister apertures, the panels are arranged such that the blisters and gates and tear strips are operationally aligned, and the means for identifying an underlying finger tab and the finger tabs and the pull tabs are operationally aligned. In yet another embodiment, a blank for forming a package for use with a blister pack comprises a first panel including gates and means for identifying an underlying pull tab, a blister pack having blisters holding items attached to the first panel and positioned such that the blisters are operationally aligned with the gates, and a second panel including tab strips having pull tabs and tear strips. Here the panels are secured such that the gates and tear strips are operationally aligned, and the means for identifying an underlying pull tab and the pull tabs are operationally aligned. The pull tabs are removable and the tear strips are at least partially removable from said second panel. Means for adhesion is provided such that the gates are not connected to the respective tear strips.
- Regarding the embodiments described herein, as well as those covered by the claims, the face panel, center panel, or back panel may or may not include a tear-resistant layer to provide structural integrity or increased child-resistance. In addition, the panels and package may be designed to include any shape or dimension that accommodates any blister pack. Further, the terms, “face”, “center”, and “back” are merely directional in order to distinguish one panel from another. Accordingly, those terms are not limitations but may be used interchangeably.
- In addition, terms such as “cut line”, “severance line”, “cut”, and “frangible line”, whether in the singular or plural, are used expansively and interchangeably to include all manner of full and partial cuts, perforations, slits, nicks, combinations thereof, and all similar means for separating an element from a surrounding panel. In some embodiments the fold or score lines may likewise be severance lines.
- Further, the terms “adhesive”, “adhesion”, “means for adhesion”, and all variations thereof as used herein will be understood by those skilled in the art to include the substantial opposite of adhesion, such that adhesion prevents the substantial or complete adhering, bonding, binding, attaching, or connecting of elements. Adhesive compositions and the chemical preparation thereof, as well as adhesive methods and the mechanical execution thereof, are known in the art.

- Referring now to the drawings, wherein like elements are represented by like numerals,
FIG. 1 is a plan view of an exemplary packaging blank 10. Thepackaging blank 10 has aface panel 12, aback panel 14, and acenter panel 16 that are hingedly connected. Theface panel 12 is hingedly connected to theback panel 14 along afoldable score line 18 and to thecenter panel 16 along afoldable score line 20. Although in this exemplary embodiment thepanels - The packaging blank 10 can be constructed from any suitable substrate material to include plastics, conventional paperboard grades, including solid bleached sulfate (SBS) paperboard of suitable weight, size, and shape, and combinations thereof. Examples of suitable substrate include Easy Seal® brand and Easy Seal Plus® self-sealing boards, presently available through the Applicant. A tear resistant layer may or may not be adhered to packaging blank 10. Tear resistant layers are often laminated to the blank before cutting. The blank 10 may also be an unbleached board, depending on the desired appearance of the final package.
- The
face panel 12 includesblister apertures 22 andfinger apertures 24. The blister apertures 22 are shaped and dimensioned to receive theblisters 25 a of ablister pack 25, each containing an item 25 b. In this illustrated embodiment, thefinger apertures 24 are shaped and dimensioned to receive a finger of a user, or some tool, in a method that will be described in more detail below. Theface panel 12 further includes foldable score lines 26. - The
back panel 14 includes tab strips 28. Eachtab strip 28 includes atear strip 30 hingedly connected to apull tab 32 along afoldable score line 34. Eachtear strip 30 is defined by aseverance line 36 and thefoldable score line 34. Eachpull tab 32 is defined by acut line 38 and thefoldable score line 34. Eachpull tab 32 aligns with arespective finger aperture 24 and eachtear strip 30 aligns with arespective blister aperture 22, when the blank 10 is folded as described below. Further, the back panel includes foldable score lines 26. - The
center panel 16 includesgates 42 andfinger tabs 44. Thegates 42 are defined byseverance lines 46 and thefinger tabs 44 are defined byseverance lines 48. Thegates 42 are aligned withrespective blisters 25 a and thefinger tabs 44 are aligned withrespective tabs 32 when the blank 10 is folded as described below. - While the illustrated embodiment shows a so-called “starter pack” with a single row of two blisters, it will be understood that alternative embodiments of the invention include any number of rows, columns, and number of blisters desired, the number, configuration, and orientation being merely design choices. Likewise, the shape and orientation of the various related elements, including the
blister apertures 22,finger apertures 24, tab strips 28,gates 42, andfinger tabs 44, are not limited to the illustrated embodiments, but may vary as desired to accommodate various blister configurations and still collectively function as described herein. - The package 50 (best shown in
FIG. 5 with a view toFIG. 2 ) is formed by inserting theblisters 25 a of ablister pack 25 into therespective apertures 22, such that theblisters 25 a protrude from theface panel 12, and folding the blank 10 as shown inFIGS. 3-5 . More specifically,FIG. 2 shows theblister pack 25 positioned so that theblisters 25 a extend throughrespective blister apertures 22, and theblister pack 25 is in a face contacting position with regard topanel 12. Next,FIG. 3 shows thecenter panel 16 is folded along afold line 20 so that eachgate 42 cooperatively aligns with arespective blister 25 a andblister aperture 22. Likewise, eachfinger tab 44 cooperatively aligns with arespective finger aperture 24. - Next, as shown in
FIG. 4 , theback panel 14 is folded to be in face contacting position with thecenter panel 16. Prior to folding theback panel 14 along afold line 18 and securing thepanels gates 42. When therespective panels tear strip 30 is in a face contacting position with relation to arespective gate 42, and secured to one another either by adding adhesive or heating self-sealing boards or any of the other means for attaching panels together, as understood by one skilled in the art, eachgate 42 will not be substantially bonded to itsrespective tear strip 30. - With reference now to
FIGS. 5 and 6 , thepackage 50 is formed from the blank 10 when thepanels respective apertures 22 andgates 42, while thepull tabs 32 are functionally aligned withrespective apertures 24 andfinger tabs 44. Eachtear strip 30 overlaps arespective gate 42 and eachtab 32 overlaps arespective finger tab 44. In some embodiments thegates 42 are secured to the backing sheet of ablister pack 25, and eachpull tab 32 is secured to arespective finger tab 44 to create adouble pull tab 32 a. - In practice, to access an item 25 b from a
package 25, a user's finger or some tool is used to locate afinger aperture 24 then press and sever thedouble pull tab 32 a (tabs 44, 32) from therespective panels double pull tab 32 a forms a grip by which a user can begin to pull atear strip 30. Pulling thedouble pull tab 32 a, the user separates thetear strip 30 from theback panel 14. Because of theseverance line 36 and adhesive B between thetear strip 30 andgate 42, thetear strip 30 is removed with little or no delamination of thetear strip 30,gate 42, oradjacent panel 14. In other words, the use of adhesive B and the tearstrip severance line 36 permits a substantially clean removal of thetear strip 30. - Removing the
tear strip 30 exposes therespective gate 42, attached to the surroundingpanel 16. Eachgate 42 impedes access to the item 25 b stored in therespective blister 25 a. To access the item 25 b theblister 25 a is pushed with sufficient pressure to force thegate 42 to sever from theadjacent panel 16 along theseverance line 46 and permit the item 25 b to be removed from thepackage 50. In some embodiments thetear strip 30 andgate 42 are fully removable, in alternative embodiments the elements are hingedly removable. - In alternative embodiments an adhesive is not applied to the
tear strip 30 orgate 42, rather an “area seal” that does not contact theseelements tear strip 30 andrespective gate 42. Likewise, bonding methods such as cold glue or tape may be used to attachvarious panels tear strip 30 to arespective gate 42. -
FIG. 7 illustrates an alternative exemplary package blank 100, according to the present invention.FIG. 8 illustrates an alternativeexemplary package 150 formed from the blank ofFIG. 7 , according to the present invention. The element numbers inFIGS. 7 and 8 are the same as the previous figures, except the prefix “1” has been added. The teaching provided withFIGS. 1-6 is applicable toFIGS. 7 and 8 . - For various reasons it may be desirable to increase the child resistance capabilities or rating of the exemplary embodiments illustrated and described above. For example, an adult with a history of heart attacks may be on a regime of nitroglycerin tablets and that adult may reside with children or grandchildren. Because of the danger of a child accessing and swallowing nitroglycerin tablets, the child resistance features of the exemplary embodiments can be enhanced as described below.
- In one exemplary embodiment of a package with increased child resistance, the tactile indicator of a
finger aperture 24 is replaced with a different means for identifying an underlying finger tab, namely a finger tab 24 a (not shown), similar to thefinger tab 44 shown in thecenter panel 16. In other words, rather than fully cutting and removing a portion of thefront panel 12 to create thefinger aperture 24, such an area is designated with a severance line and the same area remains intact until removed by the user. In other alternative embodiments, other means include treated surface areas by which the user is directed where to initiate the first push sequence of opening the package, namely thefinger tab 24, 24 a proximate theblister 25 a. In alternative embodiments the user may be directed to thefinger tab 24, 24 a by a visual indicator such as printed words, symbols, or designs. With such an embodiment therespective finger tabs respective finger tabs finger tabs - Another exemplary embodiment of a package with increased child resistance is one wherein the
tear strip 30 is joined to therespective gate 42 and/or the surroundingpanel 16. In such an embodiment no means for preventing adhesion, as described above, is used. Rather, thistear strip 30 will be more difficult to remove than the illustrated embodiment because it is bonded to the surrounding elements, and thus will likely delaminate when being pulled by the user. Further, the cuts used to define therespective severance lines tear strip 30 andgate 42, can be designed to increase the amount of resistance needed to push the item through thegate 42 and whatever part of thetear strip 30 that remains adhered to thegate 42. - As understood by one skilled in the art, the exemplary package embodiments illustrated and/or taught herein may comprise a single card, a bi-fold card, or a tri-fold card. Further, these embodiments may be constructed of a single, double, or triple panel. In addition, the invention may be practiced with a single panel or multiple discrete panels.
- It must be emphasized that the law does not require and it is economically prohibitive to illustrate and teach every possible embodiment of the present claims. Hence, the above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the invention. Many combinations and variations of combinations may be made to the above-described embodiments without departing from the scope of the claims. All such combinations and variations of combinations are included herein by the scope of this disclosure and the following claims.
