Description




BACKGROUND




This application relates to containers and, in particular, to box-like cartons which are stackable.




It is known to provide various types of lidded cartons made of cardboard, paperboard and the like. Such cartons are commonly of a substantially rectangular, parallelepiped shape so that they can be easily stacked. For example, shoe boxes are commonly stacked in shoe retailing establishments, one atop the other and with adjacent stacks in abutting side-by-side relationship on shelving or the like. It can sometimes be difficult to grasp such a shoe box to extract it from the middle of a stack, particularly if the shoe box is of the type wherein the side and end walls of the cover or lid extend all the way to the bottom wall of the base, so that there is no lid rim or lip which can be easily grasped.




It is known to provide cartons with the various types of ventilation openings and hand openings to aid in lifting and carrying large cartons. However, these arrangements may not be suitable for a relatively small cartons, such as shoe boxes or the like.




SUMMARY




This application discloses an improved stackable container which avoids disadvantages of prior containers while affording additional structural and operating advantages.




An important aspect is the provision of a stackable container with an access wall normally visible and accessible when stacked, with improved means for grasping the container and removing it from the stack.




Another aspect is the provision of a container of the type set forth with openings disposed at the junctions between the access wall and top and bottom walls.




In connection with the foregoing aspect, a further aspect is the provision of a container of the type set forth, having a base and a cover which overlaps the base, the openings extending through the overlapping portions of the base and cover walls.




A still further aspect is the provision of a foldable carton blank for forming a carton or container of the type set forth.

DETAILED DESCRIPTION




Referring to

FIGS. 1 and 2

, there is illustrated a carton, generally designated by the numeral


10


, which has wall structure including a base


11


and a cover


20


. The carton may be formed of cardboard, paperboard, or any other suitable material. In the illustrated embodiment, as will explained more fully below, the carton is formed by folding a blank along crease or fold lines, but it will be appreciate that, if desired, it could be formed by other techniques, permitting the use of other types of materials. The base


11


and the cover


20


are similar in shape, each being substantially in the shape of a rectangular parallelepiped, with the cover


20


being slightly larger than the base


11


so that it can receive the base


11


therein, all in a known manner.




The base


11


has a rectangular bottom wall


12


and a pair of upstanding side walls


13


integral with the bottom wall


12


along opposite sides thereof, and each having a folded-over reinforced distal end


14


(one shown in FIG.


1


). Also integral with the bottom wall


12


, respectively at the opposite ends thereof, are upstanding end walls


15


, each being provided with a folded-over reinforced distal end


16


(one shown in FIG.


1


). Formed through each of the end walls


15


at the upper edge thereof, midway between the side walls


13


, are semi-circular apertures


17


. Also formed in each of the end walls


15


at the junction thereof with the bottom wall


12


, and in vertical alignment with the associated aperture


17


, is an aperture


18


, having a semicircular portion in the end wall


15


and a semicircular portion in the bottom wall


12


. Thus, the base


11


forms an open-top receptacle defining a storage space therein.




The cover


20


is an open-bottom structure, having a rectangular top wall


22


, integral along opposite side edges thereof with depending side walls


23


, each having a folded-over reinforced distal end (not shown). Also integral with the top wall


22


, respectively at the opposite ends thereof, are depending end walls


25


, each having a folded-over reinforced distal end(not shown). Formed in each of the end walls


25


at the junction thereof with the top wall


22


, midway between the side walls


23


, is an aperture


27


having a semicircular portion formed in the end wall


25


and a semicircular portion formed in the top wall


27


. Also formed in each of the end walls


25


at the lower edge thereof, in vertical alignment with the associated aperture


27


, is a semicircular aperture


28


. Formed on the outer surface of at least one of the end walls


25


may be suitable indicia


29


, which could be in the form of labels or be directly imprinted on the material of the end wall


25


, and may provide identifying information, such as the nature of the contents of the carton


10


, or the like.




Referring to

FIG. 2

it can be seen that the cover


20


forms a movable closure portion of the carton


10


. The base


11


and the cover


20


are so dimensioned that, when the cover is disposed over the base


11


for closing the carton


10


, the base


11


fits within the cover


20


, so that the top wall


22


of the cover


20


rests upon the upper edges of the side walls


13


and the end walls


15


of the base


11


. In this closed condition, the cover side walls


23


and end walls


25


, respectively overlap and completely cover the base side walls


13


and end walls


15


. Thus, it can be seen that in this closed condition, the side walls


13


of the base


11


respectively cooperate with the side walls


23


of the cover


20


to form side walls of the overall closed carton, while the base end walls


15


respectively cooperate with a cover end walls


25


to form end walls of the overall carton


10


. In this closed condition, the cover apertures


28


respectively align with the portions of the base apertures


18


in the end walls


15


, while the base apertures


17


respectively align with the portions of the cover apertures


27


in the end walls


25


. Thus, the apertures


17


and


27


cooperate to form through holes


30


at the upper edges of the carton ends, while the apertures


18


and


28


cooperate to form through holes


35


at the lower edges of a carton ends. This greatly facilitates removal of the carton


10


from a stack.




For example, as in the case where the carton


10


is one of a number of shoe boxes stacked one atop the other and with adjacent stacks in abutting side-by-side relationship, the cartons will normally be stacked so that a carton end wall, typically bearing indicia


29


, will form an access wall which faces outwardly toward the user. In this regard it will be appreciated that, while indicia have been illustrated on one end wall of the container


10


, it could be provided on either or both end walls, as well as on other portions of the carton


10


, in a known manner. Preferably, the holes


30


and


35


are dimensioned so as to accommodate insertion therein of a finger or thumb of a user's hand, so that the carton


10


can be easily grasped, as by the use of a thumb and one finger of a hand, to greatly facilitate removing the carton from a stack.




Illustrated in

FIG. 3

is a blank


40


for the formation of the base


11


. A similar blank will be used for forming the cover


20


, the only difference from the blank


40


being that the cover blank will be slightly larger, as explained above. The blank


40


has a rectangular base panel


41


integral along fold lines


42


with rectangular end panels


43


. Each end panel


43


is, in turn, integral along a fold line


44


with a reinforcing flange


45


. The base panel


41


is also integral along fold lines


46


with rectangular side panels


47


, each, in turn, being integral along a fold line


48


with a reinforcing flange


49


. Each flange


49


is provided at the opposite ends thereof with longitudinally outwardly extending lock tabs


50


, and is also provided adjacent each tab


50


with an arcuate notch


51


extending to the fold line


48


. Each side panel


47


is also integral along fold lines


52


with reinforcement flaps


53


which are substantially rectangular in shape and are each spaced a slight distance from the adjacent end panel


43


. Each reinforcement flap


53


has arcuate notches


54


formed at the distal end corners thereof, defining substantially quarter-circles. Formed through the blank


40


are two circular base holes


55


, respectively having diameters disposed along the fold lines


42


and each disposed midway between the fold lines


46


. Formed through each of the end panels


43


is a circular flange hole


56


having a diameter along the fold line


44


and centered between the lateral edges of the end panel


43


. It will be appreciated that the blank


40


may be scored or creased along each of the fold lines to facilitate folding, all in a known manner.




Referring to

FIG. 4

, in assembly, the reinforcing flanges


49


may first be folded over along the fold lines


48


so that they lie along the inner surfaces of the side panels


47


, where they may be secured in place, such as by a suitable adhesive to form the reinforced distal ends


14


. In this condition, the lock tabs


50


will lie along inner surfaces of the adjacent reinforcement flaps


53


. Then the side panels


47


are folded up along the fold lines


46


, and the reinforcement flaps


53


are folded along the fold lines


52


, so that flaps


53


at the same end of the blank


40


abut each other, as seen in FIG.


4


. During this operation the lock tab


50


will be bent accordingly. When in this configuration, the corner notches


54


of abutting reinforcement flaps


53


cooperate to define substantially semicircular apertures. The end panels


43


are then folded up along the fold lines


42


until they lie against the outer surfaces of the reinforcement flaps


53


, whereupon the reinforcing flanges


45


may be folded down along the fold lines


44


, until they lie along the inner surfaces of the reinforcement flaps


53


, trapping the lock tabs


50


therebetween. The reinforcing flanges


45


may then be secured in place in this position, as by a suitable adhesive, to form the reinforced distal ends


16


. It can be seen that, when thus assembled, the semicircular apertures formed by the corner notches


54


adjacent to the base panel


41


respectively align with the portions of the base holes


55


formed in the end panels


43


, while the semicircular apertures formed by the corner notches


54


at the upper edges of the reinforcement flaps


53


respectively align with the halves of the flange holes


56


which now lie respectively along outer and inner surfaces of the reinforcement flaps


53


to form semicircular through notches.




From the foregoing, it can be seen that there has been provided an improved stackable carton which greatly facilitates removal from a stack of like cartons.
