STATEMENT RE: FEDERALLY SPONSORED RESEARCH/DEVELOPMENT
(Not Applicable)
BACKGROUND OF THE INVENTION
The present invention relates generally to baby wipes warmers, and more particularly to an improved baby wipes warmer having a liquid tank located therewithin which provides heated liquid vapors to the baby wipes for maintaining moisture and coloration of the baby wipes.
Baby wipes have been marketed in the United States for many years. Essentially, baby wipes are small pre-moistened paper or synthetic (non-woven) towelettes and are typically available in packages to the consuming public. They are primarily used to cleanse the skin of infants and small children. The wipe-fluid content for these pre-moistened wipes is generally comprised of cleansers, lotions and preservatives.
A few years after the baby wipes were introduced into the marketplace, various products for warming the wipes were made available to the public. Such products have been devised to comfort the baby wipe users from the inherent “chill” given off by the contact of the moistened wipes. For example, it is now a common practice for parents to employ the use of warm baby wipes on their children.
These warming products are generally electric operated and come in two distinct styles. One is an “electric blanket” style which is sized to wrap around the external surfaces of a plastic baby wipes container. The other is a self-contained plastic “appliance” style which warms the accommodated baby wipes with its internally positioned heating element. Though such currently known and available baby wipes warming products achieve their primary objective of warming baby wipes, they possess certain deficiencies which detract from their overall utility.
Perhaps the two greatest deficiencies of the prior art baby wipes warming products are the inabilities to sustain the moisture content and coloration of the baby wipes. More specifically, drying of the baby wipes occurs due to heating of their moisture which accelerates dehydration. Further, discoloration of the same appears to be inevitable because of a reaction of various chemicals in the wipes to heating. As such, even though these existing products may adequately warm the baby wipes, they cannot, however, seem to avoid the undesirable effects of dehydration and discoloration when warming them.
Thus, there exists a substantial need in the industry, and in the infant products manufacturing business in particular, for a baby wipes warming product that can effectively provide warmth to the baby wipes without dehydrating and/or discoloring them. Further, there exists a need for a baby wipes warming product which can achieve these objectives in a user-friendly and time-efficient manner.
BRIEF SUMMARY OF THE INVENTION
The present invention specifically addresses and overcomes the above-described deficiencies of prior art baby wipes warming products by providing an improved baby wipes warmer that can warm baby wipes while substantially maintaining their original moisture content and coloration. Briefly, in order to accomplish such objectives, the present baby wipes warmer may utilize a heatable liquid tank assembly which can provide liquid vapors to the baby wipes through its at least one vapor aperture, Alternatively, the present baby wipes warmer may use an elevated support surface such as a suspension tray in lieu of the tank assembly in which the baby wipes supported thereon can be heated while sustaining their moisture and color through vapors rising from the heated liquid pool disposed thereunderneath. These as well as other features of the present invention will be discussed in more detail infra.
In accordance with a first preferred embodiment of the present invention, there is provided a baby wipes warmer for warming baby wipes while substantially maintaining their original moisture content and coloration. Such warmer comprises a housing with a pivotally engaged lid member that can open and close relative thereto. A liquid tank assembly is disposed within the housing in such a way that its upper tank surface is vertically surrounded by the housing's interior-side housing wall and horizontally closed off by the lid member. In this respect, an inside compartment is defined which can be selectively accessed by opening and closing the lid member.
The liquid tank assembly is preferably fabricated from any heat conducting material such as metal (e.g., aluminum). The tank assembly comprises a liquid compartment which is formed between its upper and lower tank surfaces. The liquid compartment is used to hold any liquid that can produce vapors when heated such as water. By heating the liquid compartment, a portion of the liquid may change its physical state and flow into the inside compartment as vapors which helps to maintain the original moisture content and coloration of the baby wipes placed thereat. To allow the rising vapors to seep into the inside compartment from the liquid compartment, at least one vapor aperture is formed through the upper tank surface.
A heating element is disposed within the housing relative to the lower tank surface for the purpose of heating the liquid. The heating element may be located in various positions to achieve such purpose. For example, the heating element can be placed within the liquid compartment itself adjacent the lower tank surface to substantially extend thereabout. However, the heating element can also be placed outside the liquid compartment and still provide the requisite heat to the lower tank surface by being adjacent thereto. It is specifically contemplated herein that any types of heating element such as an electrically powered heating pad may be used.
In the first preferred embodiment, the upper tank surface is characterized by a generally flat support surface used for supporting the baby wipes thereon. This surface may be defined to be a part of the upper tank surface itself. In the alternative, however, the support surface can be formed by a suspension tray which is removably engaged upon a sponge material that extends through an exposed opening defined on the upper tank surface. If the latter configuration is used, the vapor aperture(s) of the upper tank surface is formed by the sponge itself as its inherent characteristics would allow the vapors to gradually flow therethrough. Moreover, a ridge may be formed around both types of support surfaces for confining the baby wipes within the physical boundary set thereby.
Further in the first preferred embodiment of the present invention, there may be provided a liquid reservoir which is set in fluid communication with the liquid compartment. The liquid reservoir may be disposed within the housing adjacent the liquid tank assembly, or alternatively mounted to an exterior of the housing. To establish fluid communication, any elongated and hollowed structure such as a conduit may be used to provide a flow channel between the reservoir and the liquid compartment. As will be demonstrated below, the liquid reservoir ensures that the liquid within the liquid compartment is always sustained at a certain level sufficient to provide adequate evaporation.
In accordance with a second preferred embodiment of the present invention, there is provided a baby wipes warmer which utilizes an elevated support surface such as a suspension tray in lieu of the tank assembly. The support surface is disposed within an inside compartment which is collectively formed by the interior-side housing wall and the upper housing wall. More specifically, the interior-side housing wall defines a generally flattened interior compartment surface used for placing the support surface thereon above the liquid level contained within the inside compartment. By doing so, the baby wipes accommodated thereon can be heated while sustaining their moisture and color through vapors rising from the heated liquid pool disposed underneath.
In accordance with a third preferred embodiment of the present invention, a liquid tank assembly in the form of an elongated central channel is embedded laterally along the flattened interior compartment surface. This assembly forming the elongated central channel includes a sponge material therewithin so that it may draw liquid out of the reservoir by capillarity. Similar to the first embodied baby wipes warmer, its upper tank surface comprises at least one vapor aperture which allows liquid vapor to travel therethrough.
In illustrating the operation for all embodied baby wipes warmers, a stack of baby wipes may be placed within the inside compartment simply by opening and then closing the lid member. The liquid contained within the baby wipes warmer should be checked to ensure that there is sufficient quantity, i.e., water level present. This can be accomplished by checking the liquid reservoir (for the first and third embodiments) or the liquid level within the inside compartment itself (for the second embodiment). Thereafter, the baby wipes warmer may be plugged into an electrical outlet in order to activate the heating element (if not already done). By following this easy-to-follow procedure, portions of the liquid can transition into vapors when sufficiently heated which then travel upwardly through the vapor aperture(s) to contact the baby wipes so that they may be maintained in constant moisturized condition and coloration.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings wherein the showings are for purposes of illustrating preferred embodiments of the present invention only, and not for purposes of limiting the same,
FIG. 1
prospectively illustrates a baby wipes warmer
10
constructed in accordance with a first preferred embodiment of the present invention. As indicated above, the baby wipes warmer
10
is adapted to warm a stack of baby wipes
12
accommodated therein while maintaining the wipes
12
in a substantially moisturized condition and with their original coloration (i.e., white). Those of ordinary skill in the art will recognize that the baby wipes warmer
10
may be formed to have a variety of external housing shapes, configurations, geometries, sizes and textures other than for that shown in the provided figures.
Referring more particularly to
FIGS. 1 and 2
, the baby wipes warmer
10
comprises a housing
14
. This housing
14
may be fabricated from any rigid material, but plastic polymer is preferred. The housing
14
is formed having a main body member
16
and a base member
18
. More particularly, the body member
16
is peripherally defined by an exterior-side housing wall
20
with a base end
22
that engages onto the base member
18
. The base member
18
is contemplated to be used for supporting the baby wipes warmer
10
on any provided surface (e.g., desktop, floor, night stand, etc.) and may optionally include a plurality of adjustable foot pads
24
for this purpose.
The housing
14
of the present baby wipes warmer
10
comprises a pivotally engaged top lid member
26
which is capable of opening and closing relative to the housing
14
. The lid member
26
may open and close utilizing any conventional methods such as using a door spring
28
, for example. When such lid member
26
is closed with respect to the housing
14
, it becomes an upper housing wall as it encloses the interior of the housing
14
from the outside. On the other hand, the opening of the lid member
26
allows access to an inside compartment
30
of the housing which will be discussed in more detail below. By accessing the inside compartment
30
, a stack of baby wipes
12
(layered or inter-folded stack) may be inserted and individually withdrawn for use.
Referring now to
FIGS. 2 and 3
, a liquid tank assembly
32
is provided within the housing
14
. More specifically, the liquid tank assembly
32
is located between the body and base members
16
,
18
when they are engaged to each other in the manner described above. Upon such placement, the upper tank surface
34
of the tank assembly
32
collectively forms the inside compartment
30
. with the interior-side housing wall
36
and the lid member
26
of the housing
14
. To describe this aspect in more detail, the upper tank surface
34
becomes vertically surrounded as the tank end
38
of the interior-side housing wall
36
is rested against the upper tank peripheral edge
40
thereof. The upper tank surface
34
is then horizontally closed off by the top lid member
26
forming the closed position. By such structural interaction, the requisite inside compartment
30
may be formed.
Although
FIG. 2
illustrates the liquid tank assembly
32
to be generally rectangular in configuration, it is expressly stated herein that the tank assembly
32
may be configured in other ways without deviating from its operational capabilities.
The liquid tank assembly
32
defines a lower tank surface
42
which is positioned beneath the upper tank surface
34
towards the base member
18
. The upper and lower tank surfaces
34
,
42
are connected to each other by a surrounding side tank surface
44
to thereby form a liquid compartment
46
within the tank assembly
32
. This liquid compartment
46
is used for holding any liquid
48
that can evaporate when sufficiently heated and thus produce vapors
49
which are able to moisturize. A type of liquid
48
which is exemplary of this nature is water. However, the use of any fluids which may safely moisturize the baby wipes
12
are foreseeable.
Because the contained liquid
48
must evaporate upon sufficient heating, the liquid tank assembly
32
should therefore be made from any material that is capable of rising in temperature in reaction to heating. It is preferred that the tank assembly
32
is fabricated from a heat-conducting material such as metal. More preferably, aluminum would be desirable for fabricating the tank assembly
32
as it reacts very well to heating.
As shown in
FIGS. 3 and 3A
, the upper tank surface
34
includes a plurality of vapor apertures
50
extending therethrough which provide fluid communication between the inside and liquid compartments
30
,
46
. The vapor apertures
50
allow the vapors
49
to pass through from the liquid compartment
46
to the inside compartment
30
so as to heat the wipes and maintain the baby wipes
12
in a constant moisturized condition and coloration. Preferably, the vapor apertures
50
are formed within the support surface
52
which is surrounded by a ridge
54
formed therearound. The support surface
52
is primarily used for accommodating the baby wipes
12
in which the surrounding ridge
54
confines them in place to prevent side-to-side movement.
Referring now to
FIG. 5
only, an alternative embodiment of the support surface
52
is depicted. In this embodiment, the upper tank surface
34
may instead define an exposed opening
56
between the ridge
54
. A support surface
52
may be disposed within this opening
56
in a manner as to extend substantially thereabout. Any structure providing a horizontal flat surface can be defined as the support surface
52
such as a suspension tray, for example. Preferably, a sponge material
58
extending through the exposed opening
56
from the liquid compartment
46
is used to removably secure the support surface
52
in place. The sponge
58
is preferred for this purpose as its naturally formed pores may simulate the vapor apertures
50
thereby permitting the vapors
49
to seep therethrough.
Referring now to
FIGS. 3-5
, a heating element
60
is provided within the housing
14
relative to the lower tank surface
42
. As noted above, the purpose of the heating element
60
is to heat the tank assembly
32
so that portions of liquid
48
are changed into vapors
49
. The heating element
60
may be disposed in various positions to achieve this purpose. One position is to locate the heating element
60
within the liquid compartment
46
so that it is immersed in liquid
48
to substantially extend adjacent the lower tank surface
42
(best shown in FIG.
4
). The heating element
60
may also be positioned outside the liquid compartment
48
to extend adjacent the lower tank surface
42
(best shown in FIGS.
3
and
5
). Although the. use of various heaters is contemplated, it is preferred that an electrically powered heating pad is utilized.
Referring now back to
FIGS. 1 and 2
, a liquid reservoir
62
may optionally be incorporated into the present baby wipes warmer
10
. However, the use of the liquid reservoir
62
is not mandatory as the liquid level within the liquid compartment
46
may be manually refilled. The liquid reservoir
62
is in fluid communication with the liquid compartment
46
. By such communication, the reservoir
62
can provide additional liquid to the liquid compartment
46
when needed. The additional liquid may be provided manually by operation of a valve device which may open and close the liquid flow into the liquid compartment
46
. The liquid reservoir
62
includes a refill cap
64
preferably fabricated from a rubber material for selectively accessing its interior.
Similar to the heating element
60
, the liquid reservoir
62
may also be located in multiple positions. For example, it can be disposed within the housing
14
adjacent the liquid tank assembly
32
(shown in FIG.
7
). Alternatively, the liquid reservoir
62
may be exteriorly mounted to the exterior-side housing wall
20
(shown in FIG.
1
). Irrespective of its positioning, the important concept to be derived is that the reservoir
62
fluid communicates with the liquid compartment
46
for providing additional liquid
48
thereto when needed. To establish fluid communication, any elongated and tubular structure
66
such as a conduit may be used to form a reservoir channel
66
between the reservoir
62
and the liquid compartment
46
. In this respect, the liquid reservoir
62
ensures that the liquid
48
within the liquid compartment
46
is always kept at a certain level which is sufficient to provide adequate evaporation.
FIG. 6
illustrates a baby wipes warmer
70
which is constructed in accordance with a second preferred embodiment. The second embodied baby wipes warmer
70
is substantially identical to the first embodiment with one major distinction. More specifically, the baby wipes warmer
70
of the second embodiment eliminates the use of the liquid tank assembly
32
. Rather, its interior-side housing wall
72
is adapted to define a substantially flattened interior compartment surface
74
which extends generally parallel to the base member
18
. By merely closing the top lid member (not shown), an inside compartment
78
is formed. A quantity of liquid
80
is directly contained within this compartment
78
.
A support surface
82
which is defined by a suspension tray
84
is disposed within the inside compartment
78
. However, it should be noted that the support surface
82
is positioned above the pool of liquid
80
as it must accommodate the baby wipes
12
thereon. The support surface
82
may be engaged upon the interior compartment surface
74
through any known process such as bonding or fastening. By utilizing this arrangement, the baby wipes
12
are adequately heated while sustaining their moisture and color through vapors
86
rising from the heated liquid pool
80
disposed immediately underneath the support surface
82
.
FIG. 7
shows a baby wipes warmer
90
which is made in accordance with a third preferred embodiment of the present invention. This warmer
90
is substantially identical to the first embodied baby wipes warmer
10
except that its liquid tank assembly
92
is fabricated in the form of an elongated central channel and is embedded laterally along the interior compartment surface
94
. This elongated central channel serving as the liquid tank assembly
92
includes a sponge
96
within its liquid compartment
98
. The sponge
96
operates to draw the liquid
100
out of the adjacently located liquid reservoir
102
by capillarity. Similar to the tank assembly
32
of the first embodiment, its upper tank surface
104
includes a plurality of vapor holes
106
which allow the liquid
100
to evaporate therethrough.
The operation of the first embodied baby wipes warmer
10
is described herein which is simultaneously representative for operations of the second and third embodied baby wipes warmers
70
,
90
. First, a stack of baby wipes
12
to be warmed is placed within the inside compartment
30
simply by opening and then closing the lid member
26
. The liquid
48
contained within the baby wipes warmer
10
should be checked to ensure that there is sufficient level present for adequate evaporation. This can be accomplished by visually checking the liquid reservoir (for the first and third embodiments) or the liquid level within the inside compartment itself (for the second embodiment). Thereafter, the baby wipes warmer
10
should be plugged into an electrical outlet (not shown) in order to activate the heating element
60
(if not already done). By following this easy-to-follow procedure, portions of the liquid
48
can transition into vapors
49
when sufficiently heated which are then provided to the baby wipes
12
so that they may be maintained in constant moisturized condition and coloration.
Additional modifications and improvements of the present invention may also be apparent to those of ordinary skill in the art. Thus, the particular combination of parts described and illustrated herein is intended to represent only certain embodiments of the present invention, and is not intended to serve as limitations of alternative devices within the spirit and scope of the invention.
