Description

Restricted Product Access Package System Field of the Invention

The present invention relates to a child access restricted / child safe packaged- product system. The invention further relates to child resistant closures for packaged-product.

Background of the invention Products such as medicaments are primarily but not exclusively packaged in blister packs comprising one or plurality of deformable protrusions formed in a flexible sheet with a closure for each of the protrusions. An area of concern with regard to blister packs has been the uncontrolled ease with which products can be dispensed. This becomes particularly important when blister packs are handled by children and / or physically challenged. . Further, establishing the authenticity and genuineness of a packaged product before use is essential as counterfeited products when consumed can cause grave harm to the patients.

Various attempts to achieve the above objectives are reported in literature

United States Patent 7201274 discloses a package having a simultaneous stop, alignment, and enhanced tamper-resistant feature, wherein the package has an outer sleeve and a slide card slidably disposed within the outer sleeve. A stop panel is disposed on an inside surface of the outer sleeve and has an extension panel extending away therefrom, wherein the extension panel enhances the tamper-resistant nature of the package. A guide panel extends along a longitudinal edge of the outer sleeve and has a length equal to or greater than a combined length of the stop panel and extension panel. The guide panel being folded over the extension panel to defined a channel between an edge of the guide panel and a score line separating first and second panels of the outer sleeve.

United States Patent 7325689 discloses a pharmaceutical package assembly that includes a tether having a fold-over card mating feature, and a fold-over card configured to house one or more pharmaceutical blisters, wherein the fold-over card includes a tether mating feature. One exemplary method of coupling the fold- over card to a tether includes forming a tether receiving recess in the front side of the fold-over card, folding the front side of the fold-over card adjacent to the back side of the fold-over card so that the tether receiving recess reveals an exposed portion of the fold-over card front side, and coupling the tether to the revealed portion of the card front side. Another exemplary method of coupling a fold-over card to a tether having a front side and a back side includes forming a fold-over card receiving recess in the tether such that when the front side of the tether is folded adjacent to the back side of the tether, the fold-over card receiving recess reveals an exposed portion of the tether, and coupling the fold-over card to the revealed portion of the tether.

United States Patent 7188728 discloses a child-resistant senior-friendly blister card packaging that is cheap and easy to manufacture. The packaging requires a push-peel-push method for opening, which is cognitively and physically challenging for children and mentally impaired adults. Yet, competent adults can easily open the package, especially after reading instructions. More specifically, opening the package requires the user to: 1) Push through a aperture to create a pull tab; 2) Pull on the pull tab to remove a panel; and 3) Push the blister to force the contents through the blister's seal. Advantageously, the present invention is designed such that information such as instructions and product information can be easily printed directly on the packaging. Moreover, users may also record information directly on the packaging. Thus, the present invention not only provides child-resistant and senior-friendly features, but also provides convenience for viewing and recording information. The review of the prior art reveals

In one of the configurations the package is engaged with the closure means wherein the said package has to be disengage and removed from the said closure means to access the package. The closure means may encompass the said package or is in the form of a tray like structure adapted to fit /holding the package. The package may be required to be disengage and separated from the closure means to access the product. Figure 1 depicts one of the embodiments of the package system. The package is housed in a hinged closure wherein the package is removably or permanently engaged with the closure or package holding provision wherein the user has to perform at least two operations to access the package. In one of the embodiment as depicted in Figure 1 , comprises of a closure means comprising at least two flexible sheets 1, 2. The portion of the sheet near edges 3 is substantially flat wherein the two sheets are hinged / attached at one of the edges 4. The sheets are disposed over each other so as to form a cavity because of the respective protrusions 5 and 6 in the first and second sheet to receive the product package 7.. The first sheet 1 comprises of a pin like provision 8 provided on the deformed surface. The second sheet 2 comprises of a provision 9 provided corresponding to the said pin like provision of the same first sheet to removably receive the said pin like provision. The said package is provided with openings 10 and 11 corresponding to the said pin like provisions. The second sheet further is provided with support 10 for the product package 7. Grooves 12 and 13 are provided on both the sheets so as to provide grip for holding the system. The disposition of the said sheets is such that when the sheets are placed over each other with the product package placed in the cavity between the said sheets, the said pin like provision of the first sheet engages with the said counterpart 9 on the sheet 2. To access the package, one has to press (apply pressure) the two sheets at the said grooves from the edges inwards so that the pressure results in bulging of the said sheets resulting in disengaging the said provisions and further facilitating access to the product package by moving (rotating) the said first sheet around the said hinged edge 4. Yet another variant of this configuration is depicted in Figure 1a. It comprises of a base 60 for holding the package 63. The base is provided with tracks 62 wherein the stifferners 65 of the package are engaged. The package is further engaged with the base with the snap 61 that is adapted to fit in the package. In operation package has to be disengaged from the said snap and further moved so as to disengage the stifferners of the package from the said tracks.

In another configuration, the packages is encased and engaged in the closure means wherein the package has to be moved out of the said closure but is still in the engaged with the closure. Figure 2 depicts another embodiment of the invention. This configuration comprises of closure and the engagement provision for the package.
