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
in the recessed chamber formed between end walls
81

includes a horizontal portion
97
extending substantially the full width between opposing end walls
81
,
83
. 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.
