Referring now to Figure 1, there is shown a container 10 having a box portion 11 for containing a stack of premoistened wipes 12 therein which are dispensed from the container after opening a lid 14.
The container 10 is substantially rectangular in configuration and includes two circular projections 16 and 18 projecting from the lid 14 and two circular recesses 20 and 22 formed at the bottom of the box portion 14, the projections being in axial alignment with the recesses when the lid is closed. The front and rear walls 24 and 26 and the first and second ends 28 and 30 are smooth surfaces upon which labels (net shown) may be placed.
Referring now mainly to Figure 2, there is shown a plurality of containers l0 stacked, with the projections 16 and 18 of one container received in the recesses 20 and 22 of the container stacked thereon.
The containers 10 may stack in a number of different ways. For example, one container 10 may stack on another with the projections 16 and 18 of the bottom container being received in the recesses 20 and 22 of a single tog container, or the containers may stack with one container overlapping two containers. The containers may be oriented either parallel or normal to the other containers in the stack, providing a wide variety of stacking arrangements.
When the containers 10 are empty, they are relatively light so that the projections 16 and 18 and recesses 20 and 22 provide a needed stability to stacks of the containers. When a customer has an infant or toddler, the wipes 12 are used at a relatively .rapid rate so that the customer is likely to accumulate a substantial number of containers 10 in a relatively shorn time, providing the customer's child with blocks which are light enough for a child to manipulate while ~:~0~83~
providing a substantial degree of resistance to unsticking when they are stacked due to projections 16 and 18 locking with adjacent recesses 20 and 22. In addition to being relatively light in weight, the containers 10 have rounded corners 32, which minimize risk of injury.
Referring now mainly to Figures 3-6, it is seen that the box portion 11 of the container 10 has a bottom, designated generally by the numeral 100, which includes a domed floor 102 upon which the stack 12 of premoistened wipes rests. The floor 102 is raised from the absolute bottom portion 104 by a distance sufficient to accommodate the depth of the recesses 20 and 22. The recesses 20 arid 22 are formed by circular walls or rings 106 (Figure 3) and 108 (Figure 6), respectively, which have a diameter complementing o:r perhaps slightly larger than the cylindrical projections 16 and 18 of an adjacent lower block. The rings 106 and 108 define the openings 16 and 18 as each having a depth no greater than the depth of the indentation in the bottom of the box portion defining the domed floor 102.
As is seen in Figure 5, the floor 102 appears as an oblong platform projecting into the box portion 11. The floor 102 has a peak 110. Surrounding the raised floor 102 is a peripheral gutter 112 in which moisture accumulates. Since the bottom wipes in the stack 12 drape over the raised floor 102, the edges of the bottom wipes will remain immersed in any moisture which pools in the gutter 112 so as to wick the moisture and keep the stack of premoistened wipes wet.
Referring now to Figures 7, 8, and 9, there is shorn a top portion, designated generally by the numeral 120, of the container 10, wherein the lid 14 is secured by hinges 122 and 124 to a rirn, designated generally by the numeral 126. As is best seen in Figure 8, the rim 126 has two relieved portions, 128 and 130, which receive the leaves 132 and 134 of the hinges 122 and 124, respectively. Hinges 122 and 124 are living hinges which each have reduced thickness portions 136 and 138, which flex to allow the lid 14 to pivot over the rim 126 to assume the phantom line position shown in Figure 9. When the lid 14 is in the: closed position shown in phantom Figure 9, it closes tree opening 140 defined within the inner perimeter 142 of the rim 126.
The relieved portions 128 and 130 of the rim 126 receive leaves 122 and 124 so as to be flush with the remaining upper surface 144 of the rim 126. Depending from a front edge 146 of the lid 14 is a latch tab 148.
The latch tab 148 includes a resilient detent 150, depended therefrom, and a finger tab portion 152. The decent 150 is received within a slot 154 in a third relieved portion 156 of the rim 126, so that the upper , surface 158 of the latch 148 is flush with surface 144 of the rim 126.
Referring now more specifically to Figure 10, where the latch 148 is shown in an enlarged view in its latched position, it is seen that the detent 152 has an enlarged end 162. The enlarged end 162 of the detent 152 is received beneath the lower edge 164 of the beveled side wall 166, defining the slot 154. A tang 170 disposed proximate the beveled wall 166 beneath the slot 154 has a projecting rib 272 with an edge 174 against which the bottom surface of the enlarged end 162 of the detent 152 presses. Rib 172 exerts a bias which urges the decent 152 against the lower edge 164 of the beveled slot wall 166, so ws to provide an interference fit which retains the detent within the slot 154. The finger tab 152 projects slightly from a downwardly extending dependent skirt 180 and is accessible by a relieved portion 182 beneath the finger tab 152. As the finger tab 152 is lifted upwardly, the detent 152 is pulled away from the edge 164 so that the lid 14 is liftable to the open position.
Referring now more specifically 'to Figures 11, 12 and 13, it is seen that the box portion 11 of the container 10 includes upper wall sections 200 which are received in slots 202, defined by an inner skirt 204, disposed in spaced relation to the outer skirt 180. The inner skirt 204 has a grove 206 therein which receives rounded ribs 208 on the inner surface of the wall 200 defining the box 11. The walls 200 each further have a land portion 210 upon which rests the lower edge 212 of the outer skirt 180, as is seen in Figure 12.
As is seen in Figure 13, the corner portions 220 of the rim 126 and the box portion 11 are different from the straight portions, shown in Figures 12 and 12, in that there is no grove 206 in the inner skirt 204, and no rounded rib 208 proximate the upper edge of wall 200.
In the preferred embodiment, the container 10 is substantially rectangular, with curved edges and corners. However, the front, rear, and side walls do exhibit a slight taper of about 3/4° to facilitate manufacture of the container from polypropylene.
In a preferred embodiment, the container has a length of 8.6~, a width of about 4.3", and a depth of about 4". gy having a length which is twice the width, it is possible to build structures having adjacent containers 10 with lengths extending normal to one another. Preferred ranges of dimensions for the container 10 include a length.of 7-9", a width of 3-5", and a depth of 3-5". A wall thickness of about 0.050"
for the polypropylene .forming the container 20 (including the rings 86 and 88) is sufficient to provide the container with necessary rigidity.
Without further elaboration, it is believed _g_ ~~~3~3~
that one skilled in the art can, using the preceding description, utilize the present invention to its fullest extent.

Referring now to Figure 1, there is shown a container 10 having a box portion 11 for containing a stack of premoistened wipes 12 therein which are dispensed from the container after opening a lid 14.
The container 10 is substantially rectangular in configuration and includes two circular projections 16 and 18 projecting from the lid 14 and two circular recesses 20 and 22 formed at the bottom of the box portion 14, the projections being in axial alignment with the recesses when the lid is closed. The front and rear walls 24 and 26 and the first and second ends 28 and 30 are smooth surfaces upon which labels (net shown) may be placed.
Referring now mainly to Figure 2, there is shown a plurality of containers l0 stacked, with the projections 16 and 18 of one container received in the recesses 20 and 22 of the container stacked thereon.
The containers 10 may stack in a number of different ways. For example, one container 10 may stack on another with the projections 16 and 18 of the bottom container being received in the recesses 20 and 22 of a single tog container, or the containers may stack with one container overlapping two containers. The containers may be oriented either parallel or normal to the other containers in the stack, providing a wide variety of stacking arrangements.
When the containers 10 are empty, they are relatively light so that the projections 16 and 18 and recesses 20 and 22 provide a needed stability to stacks of the containers. When a customer has an infant or toddler, the wipes 12 are used at a relatively .rapid rate so that the customer is likely to accumulate a substantial number of containers 10 in a relatively shorn time, providing the customer's child with blocks which are light enough for a child to manipulate while ~:~0~83~
providing a substantial degree of resistance to unsticking when they are stacked due to projections 16 and 18 locking with adjacent recesses 20 and 22. In addition to being relatively light in weight, the containers 10 have rounded corners 32, which minimize risk of injury.
Referring now mainly to Figures 3-6, it is seen that the box portion 11 of the container 10 has a bottom, designated generally by the numeral 100, which includes a domed floor 102 upon which the stack 12 of premoistened wipes rests. The floor 102 is raised from the absolute bottom portion 104 by a distance sufficient to accommodate the depth of the recesses 20 and 22. The recesses 20 arid 22 are formed by circular walls or rings 106 (Figure 3) and 108 (Figure 6), respectively, which have a diameter complementing o:r perhaps slightly larger than the cylindrical projections 16 and 18 of an adjacent lower block. The rings 106 and 108 define the openings 16 and 18 as each having a depth no greater than the depth of the indentation in the bottom of the box portion defining the domed floor 102.
As is seen in Figure 5, the floor 102 appears as an oblong platform projecting into the box portion 11. The floor 102 has a peak 110. Surrounding the raised floor 102 is a peripheral gutter 112 in which moisture accumulates. Since the bottom wipes in the stack 12 drape over the raised floor 102, the edges of the bottom wipes will remain immersed in any moisture which pools in the gutter 112 so as to wick the moisture and keep the stack of premoistened wipes wet.
Referring now to Figures 7, 8, and 9, there is shorn a top portion, designated generally by the numeral 120, of the container 10, wherein the lid 14 is secured by hinges 122 and 124 to a rirn, designated generally by the numeral 126. As is best seen in Figure 8, the rim 126 has two relieved portions, 128 and 130, which receive the leaves 132 and 134 of the hinges 122 and 124, respectively. Hinges 122 and 124 are living hinges which each have reduced thickness portions 136 and 138, which flex to allow the lid 14 to pivot over the rim 126 to assume the phantom line position shown in Figure 9. When the lid 14 is in the: closed position shown in phantom Figure 9, it closes tree opening 140 defined within the inner perimeter 142 of the rim 126.
The relieved portions 128 and 130 of the rim 126 receive leaves 122 and 124 so as to be flush with the remaining upper surface 144 of the rim 126. Depending from a front edge 146 of the lid 14 is a latch tab 148.
The latch tab 148 includes a resilient detent 150, depended therefrom, and a finger tab portion 152. The decent 150 is received within a slot 154 in a third relieved portion 156 of the rim 126, so that the upper , surface 158 of the latch 148 is flush with surface 144 of the rim 126.
Referring now more specifically to Figure 10, where the latch 148 is shown in an enlarged view in its latched position, it is seen that the detent 152 has an enlarged end 162. The enlarged end 162 of the detent 152 is received beneath the lower edge 164 of the beveled side wall 166, defining the slot 154. A tang 170 disposed proximate the beveled wall 166 beneath the slot 154 has a projecting rib 272 with an edge 174 against which the bottom surface of the enlarged end 162 of the detent 152 presses. Rib 172 exerts a bias which urges the decent 152 against the lower edge 164 of the beveled slot wall 166, so ws to provide an interference fit which retains the detent within the slot 154. The finger tab 152 projects slightly from a downwardly extending dependent skirt 180 and is accessible by a relieved portion 182 beneath the finger tab 152. As the finger tab 152 is lifted upwardly, the detent 152 is pulled away from the edge 164 so that the lid 14 is liftable to the open position.
Referring now more specifically 'to Figures 11, 12 and 13, it is seen that the box portion 11 of the container 10 includes upper wall sections 200 which are received in slots 202, defined by an inner skirt 204, disposed in spaced relation to the outer skirt 180. The inner skirt 204 has a grove 206 therein which receives rounded ribs 208 on the inner surface of the wall 200 defining the box 11. The walls 200 each further have a land portion 210 upon which rests the lower edge 212 of the outer skirt 180, as is seen in Figure 12.
As is seen in Figure 13, the corner portions 220 of the rim 126 and the box portion 11 are different from the straight portions, shown in Figures 12 and 12, in that there is no grove 206 in the inner skirt 204, and no rounded rib 208 proximate the upper edge of wall 200.
In the preferred embodiment, the container 10 is substantially rectangular, with curved edges and corners. However, the front, rear, and side walls do exhibit a slight taper of about 3/4° to facilitate manufacture of the container from polypropylene.
In a preferred embodiment, the container has a length of 8.6~, a width of about 4.3", and a depth of about 4". gy having a length which is twice the width, it is possible to build structures having adjacent containers 10 with lengths extending normal to one another.
