Abstract
A child resistant package having a panel that obstructs removal of the articles being held within the package. When the package is fully opened or fully closed, the panel offers resistance to the removal of the articles contained therein. Only when the panel is in an aligned position do holes in the panel properly align so that the articles within the package can be removed. Each article is sandwiched between a top base portion and a bottom base portion of the package such that the panel can slide in-between the base portions when the package is opened or closed.
Description




BACKGROUND




1. Field of the Invention




This invention relates to a child resistant package that offers resistance to removal of articles contained therein when a panel of the package is fully opened or closed and permits removal of the articles only when the panel is properly aligned.




2. Discussion of Related Art




Conventional child resistant packages and dispensers are well known in the art. For an example, U.S. Pat. No. 3,610,410 to Seeley discloses a tamper proof reclosable sliding panel display blister package that has a working panel


25


with a narrow slide panel


31


attached thereto. See

FIG. 3. A

back panel


23


has a removable portion


32


defined by a perforated line


32




a


to provide a port


34


for discharging articles contained within the blister packaging


19


.




As illustrated in

FIG. 4

, the sliding panel


31


can be withdrawn by bending the extending tab portion


51


rearwardly, which causes the crease


27


to serve as a hinge. The sliding panel


31


thereby moves in and out of the enclosure


44


and is retained under platform


39


and between skirts


41


. When the panel


31


is in the fully closed position, as in

FIG. 3

, the articles contained in the blister packaging are prevented from passing through the port


34


. However, when the slide panel


31


is opened or slid in a left to right direction of

FIG. 3

, the articles within the blister packaging are able to pass through the port


34


.




U.S. Pat. No. 2,971,638 to Allison et al. discloses a dispensing container having a pair of front and back sheets


20




a


and


21




a


arranged in facing relation with each other with an inner sheet


22




a


sandwiched there between. The front sheet


20




a


has an elongate opening


24




a


with numerous removable stop elements


25




a


detachably secured within the opening. Outlet openings


27




a


are formed in the back sheet


21




a


.




The inner sheet


22




a


is slidably retained between the outer sheets


20




a


and


21




a


. Formed in the inner sheet


22




a


are a plurality of depressed portions


30




a


, each of which defines a protrusion projecting forward into the front sheet opening


24




a


and a recess opening rearward towards and closed by the back sheet


21




a


. In other words, the recesses


30




a


are all closed by the back sheet


21




a


and the inner sheet


22




a


with the pills


31




a


contained therein being mounted for longitudinal shifting movement therein.




Accordingly, the inner sheet


22




a


is shiftable longitudinally until the recess portions


38


engage an undetached stop element


25




a


. This shifting places the upper most recesses


30




a


in registry with the outlet aperture


27




a


so that the pills may be discharged from the device through the apertures.




U.S. Pat. No. 2,497,455 to Johnson discloses an article dispensing container having side walls


18


and


21


, a bottom wall


20


, a top wall


22


, and inner wall


25


. Apertures


28


and


29


are formed in the top wall


22


and inner wall


25


, respectively. The container is filled with articles, such as tablets, and the like. In a closed state, the apertures


28


and


29


are offset from each other to prevent the articles from being removed.




In order to dispose the articles, a rear end wall


26


, is pivoted inwardly, as shown in

FIG. 4

, to move the inner wall


25


so as to align the aperture


29


with the aperture


28


of the top wall


22


. The container can then be turned upside down to remove the articles.




SUMMARY OF THE INVENTION




An object of this invention is to overcome the above-discussed drawbacks of the conventional child resistant packages and dispensers.




Another object of this invention is to provide a unique package that is child resistant, yet user friendly. The package is structured so that a panel of the package obstructs removal of the articles being held within. In particular, when the package is fully opened or fully closed, the panel offers resistance to the removal of the articles contained therein. Only when the panel is in an aligned position do holes in the panel properly align so that the articles within the package can be removed. Each article is sandwiched between top and bottom base portions of the package such that the panel can slide in-between when the package is opened or closed.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT




Referring to

FIG. 1

, the package


10


is formed from a flat, substantially rectangular shaped single blank


11


, ideally made from paperboard. However, it is within the scope of this invention to use any suitable material well known or later developed in the art, such as, for example only, paper, plastic and the like. A hinge


40


is formed by scoring the blank


11


at hinge folds


40




a


and


40




b


, thereby forming a cover


20


and base


30


of the package


10


.




The cover


20


is separated into a top cover portion


21


and a bottom cover portion


22


by scoring the cover


20


at cover fold


20




f


. The top cover portion


21


includes a panel


23


that extends away from the hinge


40


when the blank


11


is flat in a direction coaxial with a longitudinal axis L of the blank


11


. The panel


23


is foldable at a pivoting hinge


50


to permit the panel


23


to be manipulated between an aligned position and a non-aligned position, as will be described in further detail below. An area of the top cover portion


21


is smaller than an area of the bottom cover portion


22


. Thus, the edge


21




a


of the top cover portion


21


does not overlap the hinge fold


40




a


when the top cover portion


21


is folded over the cover fold


20




f


. See FIG.


2


.




Also, the panel


23


includes a plurality of alignment holes


24


that are used to obstruct as well as facilitate removal of the articles contained within the package


10


as will be explained in further detail below.




The base


30


is separated into a top base portion


31


and a bottom base portion


32


by scoring the base


30


at base fold


30




f


. The top and bottom base portions


31


and


32


, respectively, include a corresponding number of pockets


33


and dispenser elements


34


. The pockets


33


typically will contain blister packaging BP that is well known in the art, see

FIG. 2A

, and is made from such materials as, for example only, a clear plastic, foil, or the like.




The blister packaging BP is used to retain the articles A therein while the dispenser elements


34


may either be formed to have perforations at pf of the bottom base portion


32


or apertures so that the articles A can be pushed from the blister package BP in the pockets


33


and through the alignment holes


24


. It is within the scope of this invention to have the dispenser elements


34


comprise a foil backing that is well known in the industry. Then, the articles A are either forced through the dispenser elements


34


by breaking the perforations pf, puncturing the foil backing, or even passing unfettered through the apertures to remove the articles A from the package


10


.




An area of the top base portion


31


is smaller than an area of the bottom base portion


32


so that the top base portion


31


can be folded over the base fold


30




f


. Accordingly, the pockets


33


and dispenser elements


34


are aligned with each other and the edge


31




a


of the top base portion


31


does not overlap the hinge fold


40




b


. See FIG.


3


.




As shown in

FIG. 1

, an alignment edge


31




b


of the top base portion


31


is positioned a predetermined distance between the edge


31




a


and the pockets


33


.





FIG. 2

illustrates a top view of the package


10


with the panel


23


and top cover portion


21


folded over the bottom cover portion


22


along the cover fold


20




f


. As discussed above, the edge


21




a


of the top cover portion


21


does not overlap the hinge fold


40




a


. Furthermore, it is clear that the alignment holes


24


of the panel


23


are offset from the dispenser elements


34


of the bottom base portion


32


. Also, an alignment indicator


23




a


of the panel


23


extending from the top cover portion


21


is located intermediate the alignment holes


24


of the panel


23


and the pivoting hinge


50


a predetermined distance.





FIG. 3

illustrates a top view of the package


10


fully opened and the top base portion


31


folded over the bottom base portion


32


with the panel


23


inserted therebetween. As is evident from the drawing figure, the pockets


33


and dispenser elements


34


are aligned with each other. However, the alignment holes


24


of the panel


23


are offset from the pockets


33


and dispenser elements


34


.




The offset arrangement of the alignment holes


24


from the pockets


33


and dispenser elements


34


, respectively, can be observed by the fact that the alignment indicator


23




a


of the panel


23


is offset from the alignment edge


31




b


of the top base portion


31


. Therefore, any articles, such as pharmaceutical products like tablets, pills, etc. and candy, cannot be removed from the blister packaging BP, for example, in the pockets


33


through the alignment holes


24


of the panel


23


and passed through the dispenser elements


34


.





FIG. 4

illustrates a sectional view of the package


10


when fully closed. In other words, the cover


20


is not shown. As can be seen, the pockets


33


and dispenser elements


34


are aligned with each other. However, the alignment holes


24


of the panel


23


are offset from the pockets


33


and dispenser elements


34


.




The offset arrangement of the alignment holes


24


, pockets


33


and dispenser elements


34


can be observed by looking to verify the alignment indicator


23




a


and alignment edge


31




b


are offset, i.e., not aligned. The nonaligned status of the alignment holes


24


, pockets


33


, and dispenser elements


34


, respectively, can also be verified by the fact that the alignment holes


24


of the panel


23


are not aligned with the pockets


33


and dispenser elements


34


. Similar to when the package


10


is fully opened, when the package


10


is fully closed, the articles A are prevented from being removed from within the blister packaging BP in the pockets


33


and therefore cannot pass through the alignment holes


24


of the panel


23


and dispenser elements


34


.





FIG. 5

is a sectional view of the package


10


with the alignment holes


24


of the panel


23


aligned with the pockets


33


and dispenser elements


34


of the base top and bottom portions


31


and


32


, respectively. To accomplish such, the cover


20


is manipulated about the hinge


40


toward the base


30


until the package


10


is nearly in the fully closed state shown in FIG.


3


. The cover


20


is then manipulated about the hinge


40


such that the panel


23


slides between the top base portion


31


and bottom base portion


32


in a direction indicated by the arrow R until the alignment indicator


23




a


is aligned with the alignment edge


31




b


of the top base portion


31


.




To remove the articles A from the blister packaging BP in the pockets


33


, a user must first align the alignment indicator


23




a


on the panel


23


with the alignment edge


31




b


on the top base portion


31


in a manner discussed above. Then, the user pushes downward on the blister packaging BP, forcing the article A contained therein through the pocket


33


and alignment hole


24


. The same force then breaks either the perforations pf surrounding the dispenser elements


34


or the foil backing, if present, such that the articles A can pass therethrough. Likewise, if the dispenser elements


34


comprise apertures, the articles A will simple pass therethrough unfettered.




As such, the above-described invention provides a child resistant package using a panel that obstructs articles contained within the package from being removed by children while simultaneously providing a package that is simple to manufacture, easy to use by adults, and cost efficient.




Additionally, many modifications may be made to adapt the teachings of the child resistant package of this invention to particular situations or materials without departing from the scope thereof.




For example, it is optional, as illustrated in

FIG. 5

, to provide the top base portion


31


with indicator extensions


37


that are placed on the portion


31


beneath the edge


31




a


at a location coaxial to the alignment edge


31




b


. Thus, the alignment indicator


23




a


of the panel


23


may be aligned with the extensions


37


rather than the edge


31




b


to align the alignment holes


24


with the pockets


33


and dispenser elements


34


.




Furthermore, it should be noted that the geometric configuration of the package


10


discussed above was described as being rectangular merely for illustrative purposes as well as to simplify the explanation of this invention. It is well within the scope of this invention to provide packages of different geometric shapes, such as, for example only, circular, triangular, elliptical, square, quadrilateral, trapezoidal, and any other well known package shape.




Accordingly, the predetermined distances of the position of the alignment edge


31




a


between the edge


31




a


and pockets


33


, and the position of the alignment indicator


23




a


relative to the alignment holes


24


of the panel


23


, are to be established based on the geometric configuration of the package as well as the size of the cover


20


and base


30


.




Additionally, it is within the scope of this invention to provide more than one row of alignment holes, pockets


33


, and dispenser elements


34


. A single row of each was discussed above merely to simplify the explanation of this invention.




Therefore, it is contended that this invention not be limited to the particular embodiment disclosed herein, but includes all embodiments within the spirit and scope of the disclosure.
