DETAILED DESCRIPTION OF THE INVENTION




For purpose of illustration, the present invention has been depicted as a compact portable pack


10


for holding diapers


12


, wet baby wipes


14


, and reclosable disposable plastic bags


16


. A mother or father can conveniently carry the pack


10


about keeping the necessary supplies required to change the diaper of a baby readily available for use upon demand. The pack


10


is compact and is capable of being carried in a tote bag, a larger purse, compartment of a car, and in other convenient ways.




The pack


10


comprises a relatively rigid container base


20


of resilient plastic material having integrally formed lids


22


,


24


attached thereto. The container base


20


is generally rectangular comprising an outer sidewall


26


extending opposing ends


28


,


30


. When opening or closing one of the lids


22


,


24


, the sidewall


26


is typically oriented with the vertical orientation of the sidewall illustrated in

FIG. 4

(or rotated about 180 degrees in which the sidewall is still vertical). The reference to vertical and horizontal using the orientation illustrated in

FIG. 4

will be used herein and throughout for purposes of reference for description purposes even though the lids can be opened while the sidewall rotated to a horizontal orientation. The sidewall


26


is comprised of four upright sides


31


,


32


,


33


,


34


. The first and third sides


31


,


33


extend parallel. Similarly, the second and fourth sides


32


,


34


extend parallel. A partition wall


36


extends horizontally perpendicular to the sidewall


26


to divide the container base


20


into a wipe compartment


38


and a diaper compartment


40


at opposing ends


28


,


38


of the container base


20


. Thus, the partition wall


36


forms the bottom of each of the compartments


38


,


40


. The diaper compartment


40


may be sized to hold a maximum of about 2-6 diapers while the wipe compartment


38


is sized to hold a maximum of 10 to 20 wet baby wipes.




The first lid


22


is integrally connected to the first side


31


at the first end


28


through a live hinge


42


which is a thin flexible web of plastic material. The first lid


22


pivots via the hinge


42


between open and closed positions shown in

FIGS. 3 and 4

, respectively. The first lid


22


includes a planar horizontal rectangular cover portion


44


and first, second, third, and fourth vertically depending end walls


51


-


54


complementary to and aligned with the sides


31


-


34


of the container base


22


when in the closed position of FIG.


4


. The end walls


51


-


54


engage the sides


31


-


34


to enclose the wipe compartment


38


. A seal in the preferred form of a tongue and groove seal


55


is arranged between the lid


22


and the sidewall


26


. The seal


55


prevents liquid contained in the wet baby wipes


14


from evaporating. The tongue and groove seal


55


comprises a vertical groove


56


formed in the terminating edge of the second, third and fourth end walls


52


-


54


, and a tongue


58


projecting vertically from the sidewall


26


at the first end


28


into the vertical groove


56


. The groove


56


does not extend along the first end wall


51


due to the fact that it would be difficult to get the tongue into the groove along a horizontal line so close to the pivot point of the hinge


42


. Instead, only the outer groove wall


60


of the groove


56


extends along the first end wall


51


. The tongue


58


and outer groove wall


60


engage and horizontally interfere with each other to maintain a seal along the first side


31


of the wipe compartment


38


.




To keep the lid


22


closed and sealed on the container base


20


, a snap connection


62


is provided between the lid


22


and base


20


on the side opposite the live hinge


42


. The snap connection


62


is formed by an interlocking rib


64


and cavity


66


between the container base


24


and the lid


22


. In the disclosed embodiment, the cavity


66


is formed into a resilient lift tab


68


projecting outwardly and vertically from the third end wall


53


of the lid


22


. The lift tab


68


extends over the exterior of the container base sidewall


26


with the cavity


66


receiving the rib


64


that projects outwardly from the third side


33


. The lift tab


58


can be pulled and flexed outwardly to unsnap the snap connection


62


and release the lid


22


from the container base


20


to open the wipe compartment


38


.




The second lid


24


is integrally connected to the third side


33


at the second end


28


through a live hinge


70


which is a thin flexible web of the plastic material. It is an advantage that the lids


22


,


24


are integrally connected on different sides and preferably opposite sides of the container base


20


for manufacturing in that a two or three piece mold may be used with three plastic injection points during the blow molding process, one for the container base, and one for each lid. The second lid


24


pivots via the live hinge


70


between open and closed positions shown in

FIGS. 3 and 4

, respectively. The second lid


24


includes a planar horizontal rectangular cover portion


44


and first, second, third, and fourth vertically depending end walls


81


-


84


complementary to and aligned with the sides


31


-


34


of the container base


22


when in the closed position of FIG.


4


. The end walls


81


-


84


engage the sides


31


-


34


to enclose the diaper compartment


40


. To prevent dirt or other undesirable material from entering the diaper compartment


40


, the lid includes thin rectangular flange


86


projecting vertically toward the container base


20


from the end walls


81


-


84


that surrounds and interferes with a corresponding thin rectangular flange


88


.




To keep the second lid


24


closed and sealed on the container base


20


, a snap connection


90


is provided between the lid


24


and base


20


on the side opposite the live hinge


70


. The snap connection


90


is formed by an interlocking rib


92


and cavity


94


between the container base


20


and the lid


24


. In the disclosed embodiment, the rib


92


is formed into a resilient lift tab


95


. The lift tab


95


projects outwardly and vertically from the first end wall


81


of the lid


24


. The lift tab


95


extends over the exterior of the container base sidewall


26


with the rib


92


projecting into the cavity


94


formed in the first side


31


of the container base. The lift tab


95


can be pulled and flexed outwardly to unsnap the snap connection


90


and release the lid


24


from the container base


20


to open the diaper compartment


40


.




The second lid


24


also supports a resilient spring clip


96

. A slightly arched vertical portion


98


is joined to an end of horizontal portion


97


. The spring clip


96


is fit into a formed groove or slot


99


of the second lid


24


with a tight interference fit such that the clip


96


is not intended to be removed and a large removing force is required to remove the clip


96


. The horizontal portion


97


can be pivoted to provide clearance space for receiving, storing and removing reclosable disposable bags


16


such as plastic zip lock bags, plastic bags or other suitable bags. The bags


16


are used to store soiled baby wipes and diapers from a baby changing operation to allow for easy disposal.
