Description
SYSTEMS AND METHODS FOR CHILD-RESISTANT AND SENIOR FRIENDLY PACKAGING
Background of the Invention
[0001] Small articles or products such as medication pills are commonly packaged in blister packs. These products are often placed in blister or bubble shaped plastic receptacles and sealed with a thin layer of aluminum foil. The products are dispensed from the blister pack by applying pressure to the receptacle and pushing the product out through the foil.
[0002] Children may be able to access the products sealed in each of the blisters by performing the above steps or chewing, tearing up or otherwise rupturing such a blister pack. To make these blister packs child-resistant ("CR"), there have been attempts to (a) reinforce the plastic receptacles to make it more difficult for children to push the product through, or (b) attach additional layers of plastic or cardboard to the blister pack whereby each of the layers have to first be individually removed to gain access to the products therein.
[0003] Accordingly, there is a need for improved blister packaging that is child-resistant. There is a
need for improved blister packaging that is senior friendly.
Summary
[0004] The systems and methods described herein are directed to a child-resistant and senior friendly packaging for items such as solid dosage forms of medication. The solid dosage form may be a pill, a tablet, a capsule, a lozenge or any other dosage form. However, it will be understood that the systems and methods described herein may be applied to provide for any packaging system associated with any article or product .
[0005] The systems and methods provide packaging systems having a blister pack (e.g., a collapsible receptacle combined with a rupturable membrane) sandwiched between a plurality of protective layers. One or more protective layers disposed above the blister pack may include weak zones running along a package perimeter region. A child attempting to separate the protective layers from the blister pack may only be able to strip away the perimeter region thereby improving the security of the items in the blister pack. [0006] The systems and methods described herein may include systems for packaging at least one item. The systems comprise a blister pack for housing the item, the blister pack including a receptacle layer having at least one collapsible receptacle and a rupturable layer extending over the at least one receptacle.

Detailed Description of Illustrative Embodiments
[0030] As will be seen from the following description, the systems and methods described herein relate to a packaging system having a blister pack sandwiched between a plurality of protective layers. One or more protective layers disposed above the blister pack may include perforations running along the
perimeter region. A child attempting to separate the protective layers from the blister pack may only be able to strip away the perimeter region thereby securing the blister pack. [0031] The illustrative apparatuses, systems and methods are described below in the following order: First, an illustrative wallet-sized packaging system (See packaging system 100, FIG. 1) having a blister pack sandwiched between a plurality of protective layers is described. Second, various embodiments describing different types of protective layers are described along with corresponding mechanisms for accessing and extracting a pill. Third, a protection scheme provided along the perimeter region of the packaging system is described to prevent a child from stripping the protective layers away from the underlying blister pack. Fourth, systems and processes for assembling and manufacturing the packaging system are presented. [0032] FIG. 1 depicts packaging system 100 configured to house a plurality of pills 124. The packaging system 100 includes panel composite 102 and panels 104, 106 and 108. Panel composite 102 includes blister pack 112 sandwiched between first rigid layer 110 and second rigid layer 114. Blister pack 112 includes a plurality of collapsible receptacles 122 sized and shaped to house one or more pills 124 therein. First rigid layer 110 is disposed on top of blister pack 112 and includes a plurality of openings 126 to accommodate collapsible receptacle 122 of the blister pack 112. The first rigid layer 110 also includes zone of reduced strength 128 running along perimeter region 130. As will be described with
reference to FIGS. 9A and 9B, zone of reduced strength 128 may include perforations that allow perimeter region 130 to separate from the rest of panel composite 102 thereby protecting underlying blister pack 112. [0033] Second rigid layer 114 is disposed below blister pack 112 and may include openings aligned with each of the collapsible receptacles 122. As will be described with reference to FIGS. 2-8D, in some embodiments, second rigid layer 114 may include tabs and cuts that control access to pills 124 in blister pack 112. The tabs and cuts may provide protection against children attempting to access pills 124, but may still allow seniors to access medication. [0034] Panel composite 102 may further include one or more barrier layers 116, which may be attached to second rigid layer 114, and one or more label layers 118 attached to barrier layer 116. Label layer 118 may include any suitable material. Label layer 118 may include oriented polyamide nylon (OPA) . Barrier layer 116 and label layer 118 serve as obstacles to hinder a child from accessing pill 124 in blister pack 112. During operation, a user may carefully remove a portion of label layer 118 and then one or more barrier layers 116. The user may also have to remove a portion of second rigid layer 114 thereby gaining access to blister pack 112 from below. The user may then apply pressure to collapsible receptacle 122 to push pill 124 out of blister pack 112 and through each of the opened protective layers 114, 116 and 118. [0035] Panel composite 102 may be attached to additional panels 104, 106 and 108 by hinges 132 that allow panels 104, 106 and 108 to hingedly fold about each other. Panels 104, 106 and 108 may provide
information to a user. Panels may provide protection to blister pack 112. Panels 104, 106 and 108 may include additional information about pill 124, dosage information and/or other related information about the company. Panels 104, 106 and 108 may include identifiers such as bar codes and serial numbers. Panels 104, 106 and 108 may help to protect blister pack 112 and panel composite 102 from accidental puncture and collapse of blister housing 120. [0036] In some embodiments, as described with reference to FIG. HC, panel 104 may be folded over panel composite 102 thereby covering collapsible receptacles 122 of each of the blister housings 120. Panels 106 and 108 may then wrap around panel composite 102 to reduce the overall dimension of packaging system 100 to about the length and width of a single wallet- sized panel 102, 104, 106 and 108.
[0037] Packaging system 100 may include one or more child resistant features, described below, that are compliant with the U.S. Consumer Product Safety Commission's "Standard Classification of Child- Resistant Packages ASTM - Designation D3475 - 95." Packaging system 100 may include one or more child resistant features, described below, that pass test procedures conducted under the Poison Prevention
Packaging Act, 21 C. F. R. 295.1, in which packaging systems are given to children for a given period of time to determine accessibility. [0038] FIG. 2 depicts a cross-sectional view of an unassembled exemplary blister housing 120 in packaging system 100 of FIG. 1. Blister housing 120 includes blister pack 112. Blister pack 112 includes receptacle layer 202 attached to rupturable layer 206. Receptacle
layer 202 further includes collapsible receptacle 122 that defines cavity 204 that may be sized and shaped to house pill 124. Once pill 124 is placed in cavity 204, rupturable layer 206 is disposed on a surface of receptacle layer 202 such that pill 124 is sealed in cavity 204.
[0039] Blister pack 112 includes a plurality of blister or bubble shaped collapsible receptacles 122 that project outwardly from the surface of receptacle layer 202. Receptacle layer 202 may include transparent or translucent thermoformable materials such as polyvinyl chloride or polystyrene. Rupturable layer 206 may include rupturable materials including aluminum lidding foil or paper sheets. Rupturable layer 206 may additionally serve to seal out ambient dust and contaminants.
[0040] Blister pack 112 may be sized and shaped to house pill 124. Collapsible receptacle 122 may be dome shaped, having a semi-circular cross-section. Collapsible receptacle 122 may have other cross- sections including rectangular having curved corners . Collapsible receptacle 122 may be sized and shaped as desired depending on the nature of the application and of the contents of the packaging system. For example, receptacle 122 may be sized and shaped to somewhat forcibly hold pill 124 in place. In another example, when pill 124 is relatively soft and breakable, receptacle 122 may be sized and shaped to define a larger cavity 204 to reduce the likelihood that the tablet will be crushed.
[0041] In some embodiments, collapsible receptacles 122 are arranged as a rectangular grid on the rectangularly shaped receptacle layer 202. Receptacle
layer 202, in such embodiments, may have a length of about 100mm to about 120mm, and a width of about 65mm to about 80mm. Collapsible receptacles 122 may be separated from each other by a distance of about 3mm to about 6mm, either between the centers or the edges of the collapsible receptacles 122. Receptacles may have a diameter of about 10mm to about 13mm. Generally, collapsible receptacle 122 may have any size and any shape depending on, among other things, the size and shape of the product contained within, without departing from the scope of the invention. [0042] First rigid layer 110 is disposed on the top surface of receptacle layer 202. First rigid layer 110 includes one or more openings 126 that are aligned with collapsible receptacle 122. Collapsible receptacle 122 fits in opening 126, thereby allowing rigid layer 110 to be disposed adjacent to the portion of first rigid layer 110 that surrounds collapsible receptacle 122. First rigid layer 110 may be formed from cardboard and/or plastic materials. In some embodiments, first rigid layer 110 may be formed from polyethylene laminated rigid cardboard sheet. First rigid layer 110 may be sized and shaped as desired depending on the application without departing from the scope of the invention. First rigid layer 110 may be attached to the receptacle layer 110 with an adhesive. [0043] The adhesive may be applied to one or more regions of first rigid layer 110 and/or receptacle layer 202. As noted earlier, blister housing 120 depicted in FIG. 2 may be one of many such blister housings 120 distributed throughout packaging system 100. Depending on the location of blister housing 120, the depicted cross section in FIG. 2 may or may not
include perimeter region 130 of panel composite 102. In the illustrated embodiment, blister housing 120 (See FIG. 1) includes perimeter region 130 defined by zone of reduced strength 128. In some embodiments, first rigid layer 110 may include adhesives in one or more regions other than perimeter region 130. In some embodiments, first rigid layer 110 may include a different types of adhesives for different regions. As an example, perimeter region 130 may include a weaker adhesive than the rest of first rigid layer 110. As another example, perimeter region 130 may include a temporary adhesive while one or more other regions of first rigid layer 110 may include a permanent adhesive. Similarly, receptacle layer 202 may include one or more regions having different types of adhesives that correspond with perimeter region 130 of first rigid layer 110.
[0044] Rupturable layer 206 of blister pack 112 is disposed on second rigid layer 114. Second rigid layer 110 may be formed from cardboard and/or plastic materials. In some embodiments, second rigid layer 110 may be formed from polyethylene laminated rigid cardboard sheet. Second rigid layer 114 may include an opening or an openable closure aligned with collapsible receptacle 122 of blister pack 112. As depicted, second rigid layer 114 is attached to barrier layer 116, which is attached to label layer 118. [0045] Barrier layer 116 may be formed from any plastics including polyethylene, and/or paper materials and/or any other suitable materials. Barrier layer 116 may additionally include one or more perforation lines 208 to allow a portion of barrier layer 116 to be separated out and thereby allow access to the
underlying second rigid layer 114 and blister pack 112. Various embodiments of barrier layer 116 are depicted in FIGS. 3A-8D.
[0046] Label layer 118 may be formed from plastic, paper or any other suitable materials. Label layer 118 may be formed from polyethylene materials. Label layer 118 includes printed material that may be used to provide the user with additional information about pill 124 such as dosage, timing and chemical ingredients. Label layer 118 may also serve as an additional protective layer. Various embodiments of label layer 118 are depicted in FIGS. 7A-8D.
[0047] Turning to FIGS. 3A-8D, various mechanisms for accessing and extracting pill 124 are described. In particular, FIGS. 3A-3D depict a process for accessing and extracting the contents of blister housing 300 of an exemplary packaging system. Blister housing 300 may be similar to blister housing 120. Blister housing 300 includes blister pack 312 that may be sandwiched between first rigid layer 310 and second rigid layer 314. Blister pack 312 includes receptacle layer 332 disposed on rupturable layer 336. Receptacle layer 332 includes collapsible receptacle 322 that defines cavity 334 that is sized and shaped to house the pill 124. Blister housing 300 further includes barrier layer 316.
[0048] Second rigid layer 314 includes orifice 350 that may be sized and shaped based on the size and shape of pill 124. As evident in FIG. 3D, orifice 350 may have a circular shape. The diameter of orifice 350 may be selected to substantially match the width of pill 124. Generally, any dimension of orifice 350 (having any shape) may be selected to match any
dimension of pill 124 without departing from the scope of the invention. In housing 300, since pill 124 and orifice 350 are of substantially similar dimensions, pill 124 may be pushed through second rigid layer 314 only when oriented and positioned to align with orifice 350. Therefore, such a mechanism may impede but not prevent the extraction of pill 124.
[0049] Barrier layer 316 includes tab 356 that are defined by perforation lines 352 on bottom surface 360 (FIG. 3D) of blister housing 300. In the depicted embodiment, perforation lines 352 may form the circumference of a disk shaped region such that tab 356 forms the disc shaped region therein. A portion of the disk shaped region may be removed to form slot 354. Slot 354 allows a user to grip tab 356 and thereby aid in its removal .
[0050] During operation, as depicted in FIG. 3B, a user may grip and pull tab 356 by inserting a fingernail in slot 354 to release tab 356. The user may then pull tab 356 along perforation lines 352 to reveal the underlying orifice 350. As shown in FIGS. 3C and 3D, to remove pill 124 from blister housing 300, the user may first align pill 124 with a region near orifice 350 and applies pressure to collapsible receptacle 322 to cause it to collapse 322' and force pill 124 out. If aligned in proximity to orifice 350, pill 124 may be forced out by rupturing rupturable layer 336 and sliding pill 124 out through orifice 350 and blister housing 300. [0051] In some embodiments, as depicted in FIGS. 4A- 4D, second rigid layer 414 may be modified to include semi-circular opening 450. In such embodiments, opening 450 may be sized and shaped to align with a
portion of collapsible receptacle 322. A user attempting to extract pill 124 would have to move pill 124 by tilting entire blister housing 400 such that pill 124 lies above opening 450. The user may then extract the pill by collapsing collapsible receptacle 322 to force pill 124 out through rupturable layer 336, second rigid layer 414 via opening 450, and barrier layer 316. [0052] In some embodiments, second rigid layer is configured with one or more cuts or incisions that bend away to allow pill 124 to pass out from blister pack 112. FIGS. 5A-5D depict cross-sectional views of such an embodiment and FIGS. 6A-6C depict a bottom perspective view of such an embodiment. In particular, second rigid layer 514 includes set of cuts 550 that are configured as a cross-hair or intersecting cut lines to define four triangular leaves 572a, 572b, 572c, and 572d (generally, "leaves 572") . Other embodiments may include a different number of leaves, such as 2, 3, 5, 6, 7, 8 or any other suitable number of leaves.
[0053] During operation, tab 356 (FIGS. 3A-3D) , may be peeled away along perforation lines 352 to reveal the underlying second rigid layer 514 as shown in FIG. 6B. A user may apply pressure to collapsible receptacle 322 to force pill 124 through rupturable layer 336 and second rigid layer 514 such that leaves 572 bend away to allow pill 124 to pass through. [0054] In alternative embodiments, second rigid layer 514 may include a plurality of intersecting cuts 550 to generate a plurality of leaves 572. As an example, second rigid layer 514 may include four intersecting cuts 550 that define eight leaves 572. In
other embodiments, cuts 550 may be configured in other geometrical patterns such as an "I" shape with one central cut and two cuts on both ends of the central cut . [0055] As noted earlier, the blister housing may also include label layer 118 which may be configured to serve as an additional protective layer. FIGS. 7A-7D and 8A-8D depict two types of blister housings 700 and 800 having a label layer 118, and the corresponding processes for accessing and extracting pill 124. In particular, FIGS. 7A-7D depict blister housing 700 that requires a user to peel away two layers prior to forcing pill 124 from blister pack 112. Blister housing 700 includes blister pack 112 sandwiched between first rigid layer 110 and second rigid layer
114. Second rigid layer 114 includes opening 750 that is aligned with collapsible receptacle 122 of blister pack 112. Barrier layer 116 and label layer 118 are disposed on blister pack 112 adjacent second rigid layer 114. Both barrier layer 116 and label layer 118 include one or more perforation lines that define peelable tabs 756 and 758. Barrier layer 116 includes tab 758 and label layer 118 includes tab 756. In some embodiments, the perforation lines include two parallel lines of perforation and a terminating line of perforation connecting the two parallel lines, such that tabs 756 and 758 may be removed by lifting the tabs at the terminating perforation and peeling the tabs between the parallel perforation lines. [0056] During operation, a user peels away tab 756 of label layer 118 to reveal the underlying barrier layer 116. The user may then peel away tab 758 associated with barrier layer 116 to reveal the opening
750 and underlying rupturable layer 206. The user may remove the pill 124 by applying pressure to collapsible receptacle 122 to force the pill through rupturable layer 206 and each of second rigid layer 114, barrier layer 116 and label layer 118.
[0057] In some embodiments, barrier layer 116 and label layer 118 are attached to each other using adhesives. In such embodiments, tabs 758 and 756 may be attached to each other using a weaker temporary adhesive while the rest of barrier layer 116 and label layer 118 may be attached to each other using a stronger more permanent adhesive.
[0058] FIGS. 8A-8D depict blister housing 800 that requires a user to peel away outer label layer 118 and then push to puncture a portion of inner barrier layer 816, prior to forcing pill 124 from blister pack 112. Inner barrier layer 816 may include one or more lines 852, such as clean cuts, perforations or partial cuts. During operation, a user peels away tab 756 of label layer 118 to reveal the underlying barrier layer 816. The user may then apply pressure to a region on or near lines 852 to puncture a portion of barrier layer 816 thereby gaining access to rupturable layer 206. The user may remove pill 124 by applying pressure to the collapsible receptacle 122 to force pill through rupturable layer 206 and each of second rigid layer 114, barrier layer 116 and label layer 118. [0059] Turning now to FIGS. 9A and 9B, a protection scheme provided along the perimeter region of the first rigid layer is described to prevent a child from stripping the protective layers away from the underlying blister pack. In particular, FIGS. 9A and 9B depict exemplary corner region 900 of packaging
system 100 of FIG. 1. Corner region 900 of panel composite 102 (FIG. 1) includes zone of reduced strength 128 (e.g., a line of perforated cuts) the runs along an edge to define perimeter region 130. In some embodiments, zone of reduced strength 128 includes various types of perforations, clean cuts or partial cuts .
[0060] As depicted in FIG. 9A, the protective layers may be separated from blister pack 112 by releasing the first rigid layer at corner 902. However, corner 902 is located in perimeter region 130 defined by zone of reduced strength 128. Therefore, when corner 902 is pulled, instead of separating or delaminating the entirety of one or more protective layers, only perimeter region 130 is removed along zone of reduced strength 128, as shown in FIG. 9B .
[0061] Having described exemplary packaging systems with a blister pack and one or more protective layers, and exemplary materials, applications and other features, exemplary methods of manufacturing such apparatuses and systems are now described with reference to FIGS. 10, 11A-11C. In some embodiments, wallet-shaped packaging system 100 of FIG. 1 is manufactured by combining one or more rigid panels with the blister pack as shown in FIG. 10. In particular, FIG. 10 depicts panel sheet 1000 that may be assembled together with a blister pack to yield a packaging system having blister housings similar to blister housing 300 of FIG. 3.
