Description

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of U.S. Provisional Application No. 60/736,732, filed Nov. 15, 2005, herein incorporated by reference.

BACKGROUND

The invention is directed to child resistant, senior friendly packaging designed to securely hold multiple unit dose products and formed out of natural fiber or synthetic materials, or any combination thereof.
The field of packaging is challenged to provide the end user with packaging designed, or constructed, to hold multiple unit doses in a package that is child resistant and yet senior friendly. The criteria of child resistance requires a package be designed in a manner so that it is extremely difficult for a child (under the age of five) to gain access to any of the unit doses. The criteria of senior friendliness requires a package that is designed to have the unit doses easily accessed by a mature adult who may be arthritic or weak. Clearly, these two criteria are difficult to balance, i.e., making a package difficult for a child to open, but easy for a senior to open.
Known packages, in their most basic form, may simply rely on features such as pull tabs to cover the cell cavities holding the unit dose product. tabs to cover the cell cavities holding the unit dose product. Examples of such packages are disclosed in U.S. Pat. Nos. 3,129,817; 3,610,410; 3,809,220; 3,809,221; 3,811,564; 3,835,995; 3,872,970; 3,899,080; 3,905,479; 3,912,081; 3,912,082; 3,921,805; 3,924,746; 3,924,747; 3,941,248; 4,011,949; 4,120,400; 4,125,190; 4,192,422; 4,231,477; 4,485,915; 4,506,789; 5,046,618; 5,172,812; 5,310,060; 5,529,188; 6,047,829; 6,375,956; and 6,523,691 as well as U.S. patent publication nos. 2001/0017273; 2002/0185404; and 2003/0064381.
These references and any other reference cited herein are incorporated by reference.
Tabs designed in such a manner, which are difficult for children to remove, are normally not senior friendly; conversely, tabs that can be easily removed by mature adults are normally not child resistant. Integrated tabs of this type can be defined as “first level” resistance in paperboard packaging.
In certain instances, it maybe desirable if the package requires the individual to perform a sequence of steps, perhaps simultaneously. An illustration of this is for an individual to first read a set of specific instructions and then perform a sequence of steps simultaneously. For example, the product can be opened by holding package in the left hand, while pressing down on a lock release, and pulling out a slide card with the right hand. Typically, children under the age of five have great difficulty reading and comprehending instructions, while simultaneously attempting to perform a series of sequential steps, thereby rendering the package child resistant. Examples of this are disclosed in U.S. patent publication nos. 2004/0099565 and 2004/0045858, as well as U.S. Pat. No. 6,752,272.
However, a complete packaging system designed with the aforementioned features can be further defined as both child resistant and senior friendly. For example, Mature adults are able to read and comprehend instructions and can perform a series of sequential steps simultaneously.
Such a multi step packaging system is advantageous in that it prevents young children from accessing unit dose products, while allowing mature adults access to the individual unit doses contained therein. Additionally, this type of package can be opened and closed repeatedly, which is particularly advantageous when there are unused unit doses remaining inside the package. A package, as described, can continue to provide reassurance that the complete package maintains its child resistant and senior friendly characteristics throughout the dispensing life of the package.
Known packaging systems containing both child resistant and senior friendly features are disadvantageous, in that certain mature adults may find it difficult to gain access to the unit dose product. For example, an adult with arthritis in the joints of the hands may have difficulty in performing a series of sequential steps, such as grasping and holding the package, pressing down on a lock release, and pulling out a slide card containing unit dose product. Such packaging systems, which encumber access to the unit dose product by a mature adult, may have the very features, which are child resistant, circumvented in such a manner that the complete package no longer provides child resistance.
Therefore, it is preferable to provide an option whereby the child resistant features can be disengaged, long term. For example, some styles of child resistant bottle caps are manufactured with one end containing internal screw threads and a locking mechanism, while the opposite end contains external screw threads only. Such a system is disclosed by U.S. Pat. No. 6,926,161.

SUMMARY

It is the object of the invention to provide a complete packaging system containing multi step child resistance and senior friendly features. In addition, this packaging system may be configured to allow for long term disabling of the child resistant features.. Within the scope of this new invention is a multiple lock system, a detachable and reusable access card and card slot.
This object is solved according to an embodiment of the invention by providing a lock system, designed into a single integrated or unibody package, which is released through the use of a detachable and reusable access card. The invention is to be broadly construed as any single integrated or unibody package with a lock system released by any type of reusable card. For example, a credit card, picture ID card, or drivers license. However, the preferred embodiments described below utilize a packaging system formed out of paperboard, natural fiber or synthetic materials or any combination thereof and designed to securely hold multiple unit dose products.
According to preferred embodiments of the invention, an outer folding carton, containing a detachable and reusable access card, and an internal slide tray are formed out of paperboard or synthetic paperboard material, or any combination thereof.
The access card is detached from one of a plurality of side panels and inserted into a card slot in one of a plurality of end panels.
Should the access card remain in the card slot, the multiple lock system is temporarily disabled and the package is placed into a non-child resistant, or open state. Removing the access card reactivates the multiple lock system and returns the package to the previously child resistant condition.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

An embodiment of the invention comprises an outer folding carton containing a detachable and reusable access card, and an internal slide tray.
FIG. 1 illustrates an exemplary outer folding carton 10, comprising a plurality of panels 12, 16, 20, 24, 28 that are designed to be folded along fold portions 14, 18, 22, 26 with selected panels glued together. A first panel 12 is folded along a first fold portion 14, and then the first panel 12 along with a second panel 16 are folded along a second fold portion 18 and the first panel 12 is glued to a third panel 20 such that a gap approximately the width of the first 14 and second 18 fold portion is formed between a) the glued first 12 and third 20 panels, and b) the second panel 16. The first three panels 12, 16, 20, when assembled, comprise a first primary section 100 that will hold the internal slide tray 50.
The first panel 12 has a tab 44 that is used as a protruding guide for the access card 34 card when the carton is assembled. The lower pane extension 40 of the second panel 16 and the lower panel extension with slot 38 of the third panel 20, when assembled, extend in a direction perpendicular to the plane of the drawing page, creating depth or thickness to the carton and thereby forming a corner at which the access card slot 42 is present.
It should be noted that the description below refers to the slide tray 50 in an embodiment of the invention. However, the invention contemplates any slidable element, such as a movable tray, slide card or package.
The fourth panel 24 and the fifth panel 28 are glued together at selected portions along fold line 26 and form a second primary section 110. Thus, in its assembled condition, the outer folding carton appears as two primary sections 100, 110, each having panels glued together. The first primary section 100 comprises the first through third panels 12, 16, 20, and the second primary section 110 comprises the fourth and fifth panels 24, 28. The first three fold sections 14, 18, 22 have two fold lines so that the panels are separated from one another with a distance sufficient to accommodate the thickness of the internal slide tray 50. During manufacturing the first panel to be folded and glued will be panel 28, followed by panel extensions 48, then panels 12 and 16.
The internal slide tray 50, as illustrated in FIG. 2, comprises a first panel 54 and a second panel 56 that are folded together along a fold portion 52. These panels are configured to hold, e.g., single dose units, such as a bubble pack 60′, although obviously any mechanism for holding the product can be utilized. The fold portion 52 comprises two fold lines so that the panels 54, 56, when folded together, have a gap between them large enough to accommodate the product.
The internal slide tray 50 further comprises an end tab 58 that may further comprise two sub-tabs 59. This tab 58 and sub-tabs 59 are configured to interact with the outer folding carton 10 in a manner that will be explained below.
It should be noted that the internal slide tray 50 is formed from two separate cardboard layers. The internal slide tray 50 may be constructed either as a single piece unit (the top and bottom layers simply folded over) or as a two-piece unit, as illustrated in FIG. 11, where the two pieces are affixed one on top of the other. Accordingly, it can be seen that a perforated bottom portion of the single dose unit bubble pack 60′ would be matched with a top portion which is a hole having the general shape of the dose unit. A plastic portion of the bubble pack 60′ would then protrude through this top portion hole. FIG. 11 illustrates the bottom layer 54 and top layer 54′ of the first panel of the internal slide tray, the bottom layer 52 and top layer 52′ of the fold portion of the internal slide tray, and the bottom layer 56 and top layer 56′ of the second panel of the internal slide tray. The end-tab 58 and sub-tab 59, discussed in more detail below, need only be present on one of the layers. An additional end tab 58′ may be provided for support.
In its assembled state, as illustrated by FIG. 3A, the outer folding carton 10 comprises the second primary section 110 on top. The fourth panel 24 and fifth panel 28 are glued together in portions. The fourth panel comprises a cover tab 30 that inserts into a cover tab slot 32 in its closed position.
FIG. 3B illustrates the outer folding carton 10 in an initially opened pre-use state. The cover tab 30 has not been separated from the fifth panel 28 and is still attached by a perforation. Similarly, an access card 34 remains attached to the fifth panel 28 before it has been separated and inserted into the access card storage slot 36. The user would partially separate the cover tab 30 from its perforations so that the tab 30 is hinged to the fifth panel 28 upon first use. Similarly, the user would completely separate the access card 34 and insert it into the access card storage slot 36.
FIG. 4 illustrates the outer folding carton 10 in its initially opened, but locked, configuration after the tab 30 and access card 34 have been separated. The access card 34 is removed from its position on the fifth panel 28 (which may be originally perforated to permit its easy separation from the fifth panel 28) and inserted into a card storage slot 36 where it can be kept when the assembly is not in use. The second primary section 110 is attached to the first primary section 100 via the third fold portion 22. In this open configuration, the second panel 16 is visible on the right-hand side. It should be noted that the image FIGS. 3-10 reflect a carton that has been cut to reveal detail. The split-open portions of the first primary section 100 at the bottom and right-hand side would ordinarily be joined to the first primary section 100 in normal use. In the configuration shown in FIG. 4 (the locked configuration), the internal slide tray cannot be removed for reasons that are explained in more detail below.
It should be noted that in one embodiment, the access card 34 is the same width as a standard credit card or driver's license, so that in the event the access card 34 is lost or damaged, the user can still make use of the package using the standard credit card or drivers license. Furthermore, it is also possible that a holding mechanism may be provided so that the access card can be permanently installed to allow access for situations where, e.g., there are no children present or when the convenience of a non-child resistant design is desired. The holding mechanism can comprise glue, adhesive, cohesion, or physical elements, such as some form of interference, frictional, magnetic or other known holding mechanisms.
FIG. 5 illustrates the insertion of the access card 34 into a card slot 42 on the third panel 42. When the access card 34 is fully inserted, the internal slide tray 50 can be extended permitting access to its contents.
FIG. 6 illustrates the unlocked configuration of the assembly. The access card 34 is fully inserted into the slot 42, and the internal slide tray 50 is partially extended. In FIG. 6, the first panel of the internal slide tray 54 is visible, as are the perforated tabs 60 on the backside of the single dose unit bubble packs 60′.
As can be seen in FIG. 7, when the internal slide tray 50 is extended, it can be unfolded along fold portion 52′ and the full contents on both the first 54′ and second panels 56′ are visible and accessible.
FIG. 8 illustrates a cut-away view of the outer folding carton 10 that would normally not be visible during normal use, since the first panel 12 is glued to the third panel 20. To create the cut-away view, a slice has been made along the second fold portion 18 that normally connects the second panel 16 and the third panel 20. This view reveals the first fold portion 14 that connects the first panel 12 and the second panel 16. The second panel 16 comprises a flap 48 that is glued to the second panel 16 for strength and stability. In this view, the access card 34 can be seen in its inserted position.
FIG. 9 is similar to FIG. 8, except that the access card 34 has been withdrawn to reveal the presence of locking holes 46 present in the first panel 12. A card stop 34′ can also be seen. The card stop 34′ being wider than the slot 42 prevents the access card 34 from being inserted so far so that it cannot be retrieved after use.
FIG. 10 is similar to FIG. 9, except that the internal slide tray 50 has been flipped over to reveal the locking mechanism. Accordingly, without the access card 34 being inserted, the sub-tabs 59 engage the locking holes 46 due to a slight bias of the sub-tabs 59 against the surface of the first panel 12 created by the fold connecting the end tab 58 to the second panel 56 of the internal slide tray 50. Since this second panel 56 of the internal slide tray is normally pressed against the surface of the first panel 12, the sub-tabs 59 get caught in the locking holes 46 and prevent the internal slide tray 50 from being extended.
However, once the access card 34 has been inserted, it covers the locking holes 46 and prevents the sub-tabs 59 from engaging these holes. The internal slide tray 50 can then be extended until its end tab 58 engages the non-glued flap 48′ of the first panel 12 and prevents removal of the internal slide tray 50. The internal slide tray 50 can then easily be re-inserted, and the card 34 removed and placed back in the card storage slot 36 for safe keeping.
FIG. 12 illustrates an embodiment utilizing a storage area 36′ for holding leaflets, enclosures, customer instructions, regulatory information, sales or marketing information, or product literature.
FIG. 1A illustrates an alternate simplified three-panel embodiment of the invention. The primary difference is that the access card 34 has an access card tab 34″ that is initially affixed to the first panel 12 at an upper notch portion 13 of first panel 12 via perforations or other know affixing mechanism. A user access portion 13′ is provided within the upper notch portion that is not filled with the tab 34″ initially, which permits the user to separate the access card 34 from the first panel 12 upon first use. FIG. 1A also illustrates a pattern of four locking holes 46 in the third panel that provides an enhanced locking function. These offset holes are designed to interface with the subtabs 59 of the internal slide tray 50.
