Description




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 which is adapted to provide 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 electrically 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 content 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 at least one vapor aperture. Alternatively, the present baby wipes warmer may individually or collectively use an elevated support surface such as a suspension tray and/or a sponge layer in lieu of the tank assembly in which the baby wipes supported thereon can be heated while sustaining their moisture and color through vapors generated therewithin. 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. Optionally, the inner surface of the lid member may be layered with sponge materials to contain condensations which result from liquid evaporations in order to reduce the risk of spillage when it is opened. This optional feature of the lid member may be provided in all of the preferably embodied baby wipes warmers discussed herein.




The liquid tank assembly is preferably fabricated from any heat conducting material such as metal (e.g., aluminum) or plastic. 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 many 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 first liquid reservoir which is set in fluid communication with the liquid compartment. The first 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 first 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 a first elevated support surface such as a first suspension tray in lieu of the tank assembly. The first 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, there is provided a baby wipes warmer which is similar to the second embodied baby wipes warmer but additionally utilizes a sponge layer. More specifically, a second elevated support surface is provided on the interior compartment surface of the baby wipes warmer. The second elevated support surface forms therethrough a plurality of vapor holes which allow vapors to pass through. A sponge is directly layered upon this elevated surface and the baby wipes are supported upon such sponge layer. By forming such configuration, the liquid vapors rise from the pool of liquid (upon heating) through and around the second support surface to warm and moisten the wipes, not to mention warmly moistening the sponge layer which enhances the warm moisturizing effect on the baby wipes. Optionally, an exteriorly located liquid level indicator may be placed in fluid communication with the liquid pool (via a small pipe or the like) so as to provide convenient visual indication of the existing liquid level.




In accordance with a fourth preferred embodiment of the present invention, a baby wipes warmer similar to the second embodied baby wipes warmer is provided. However, this baby wipes warmer does not use any type of elevated surface but rather places a layer of sponge directly upon its interior compartment surface. The sponge layer itself retains liquid to thereby dissipate the same as liquid vapors upon generation of sufficient heat. Moreover, the sponge layer may be treated with anti-microbial or anti-bacterial additives to prevent mold, mildew and unpleasant odors. By resting the baby wipes directly upon the sponge layer, the heated sponge acts to keep the wipes warm, moist and substantially without discoloration while inhibiting growth of potentially undesirable bacteria and microbes. As will be recognized, the layer of sponge can be formed as an insert for placement within the interior of conventional prior art baby wipes warmers for retrofit applications.




Further in the fourth embodiment of the present invention, a second liquid reservoir may be used in conjunction with the fourth embodied baby wipes warmer to maintain hydration of the sponge layer and baby wipes. A vertically mounted sponge wall is provided with the second liquid reservoir and is used to absorb the necessary liquid therefrom via at least one reservoir hole extended therethrough. The absorbed liquid is then evaporated into the baby wipe warmer's inside compartment, hence adding moisture to the baby wipes disposed therein. Simultaneously, the vertical sponge wall is disposed in abutting contact with the sponge layer so that the liquid drawn from the reservoir permeates thereto and helps to maintain the moisture content of the sponge layer. The second liquid reservoir includes an external viewing port which lets a user see the level of liquid contained therein. If the liquid level is low, then the user may pour additional liquid either directly within the inside compartment or the reservoir.




In accordance with a fifth 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 and/or content) present to generate optimal vapors necessary to moisten the baby wipes. This can be accomplished by checking the liquid level within the inside compartment itself and/or the liquid reservoir (for the first, second, third and fifth embodiments) or the moisture content of the sponge layer (for the fourth 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.





FIG. 11

demonstrates the use of a top lid member


27


which is differently configured than the lid member


26


discussed above. More specifically, this differently configured lid member


27


includes the use of a sponge material


29


which lines the inner lid surface


31


thereof. It should be expressly emphasized herein that the application of sponge material


29


on the inner lid surface


31


is an optional feature which may be provided at the time of manufacturing or retrofitted thereafter. In this respect, such top lid member


27


may be utilized in conjunction with all the preferably embodied baby wipes warmers portrayed throughout this application.




The sponge material


29


may be applied to the inner lid surface


31


in any conventional manner such as through the use of adhesives, tapes, fasteners or the like. The importance of sponge material


29


is realized in that it serves to capture the condensation which forms as the result of liquid evaporation. More particularly, liquid vapors within the baby wipes warmers rise upwardly toward the inner lid surfaces


31


where condensation forms. Consequently, when the top lid members


27


are opened to retrieve the baby wipes


12


, condensation often drips down which may damage adjacent surfaces where the baby wipes warmer is positioned (e.g., wood changing table). To prevent such unnecessary consequences, the addition of a sponge material to the inner lid surfaces


31


serves to capture the condensation and lessen the risk of spill damage caused when the lid members


27


are opened.




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. It is also expressly contemplated herein that the tank assembly


32


may be fabricated from any number of plastic materials in lieu of metal.




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. It should be noted herein that the description of the heating element


60


not only applies to the baby wipes warmer


10


of the first preferred embodiment, but extends to other preferably embodied baby wipes warmers as well.




Referring again to

FIGS. 1 and 2

, a first liquid reservoir


62


may optionally be incorporated into the present baby wipes warmer


10


. However, the use of the first liquid reservoir


62


is not mandatory as the liquid level within the liquid compartment


46


may be manually refilled. The first 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 first 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 first 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 first 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 first 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 first support surface


82


which is defined by a first suspension tray


84


is disposed within the inside compartment


78


. However, it should be noted that the first support surface


82


is positioned above the pool of liquid


80


as it must accommodate the baby wipes


12


thereon. The first 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


.




Referring now to

FIG. 10

, there is provided a baby wipes warmer


90


which is manufactured according to a third preferred embodiment of the present invention. In particular, this baby wipes warmer


90


is very similar to the baby wipes warmer


70


of the second embodiment. However, the two warmers


70


,


90


differ in that the baby wipes warmer


90


of the third embodiment additionally utilizes a sponge layer


92


. More particularly, a second elevated support surface


94


which is defined by a second suspension tray


96


is disposed within the interior compartment surface


98


of the baby wipes warmer


90


above the pool of liquid


100


. A plurality of surface vapor holes


102


are formed through the second elevated support surface


94


which allow the heated vapors


104


to flow therethrough.




A sponge


92


is directly positioned upon the second elevated support surface


94


and the baby wipes


12


are rested upon the upper surface of sponge layer


92


. In this regard, the heated liquid vapors


104


rise from the pool of liquid


100


(upon heating) through and around the second support surface


94


to warm and moisten the wipes


12


, as well as warmly moistening the sponge layer


92


which by the way enhances the warm moisturizing effect on the baby wipes


12


. Optionally, an exteriorly located liquid level indicator (not shown) may be placed in fluid communication with the pool of liquid


100


(via a small pipe or the like) so as to provide convenient visual indication of the existing liquid level.





FIG. 8

shows a baby wipes warmer


110


which is manufactured in accordance with a fourth preferred embodiment of the present invention. This baby wipes warmer


110


is also similar to the baby wipes warmer


70


of the second preferred embodiment with some notable distinctions. Specifically, the baby wipes warmer


110


of the fourth preferred embodiment does not use any type of elevated surface but rather places a layer of sponge


112


directly upon its interior compartment surface


114


. As such, the sponge layer


112


itself retains poured liquid to thereby dissipate the same as heated liquid vapors


115


upon generation of sufficient heat. Further, condensation resulting from liquid evaporations may run down the lid member (not shown) and the interior-side housing wall


117


of the baby wipes warmer


110


to re-hydrate the sponge layer


112


.




Optionally, the sponge layer


112


may be treated with anti-microbial or anti-bacterial additives to prevent mold, mildew and unpleasant odors. By resting the baby. wipes


12


directly upon the such treated sponge layer


112


, the heated sponge


112


acts to keep the baby wipes


12


warm, moist and substantially without discoloration, while simultaneously inhibiting growth of potentially undesirable bacteria and microbes. Those skilled in the art will recognize that the sponge layer


112


may additionally be formed as a separate sponge insert for retrofit use in conventional prior art baby wipes warmers.




Referring now to

FIGS. 9 and 9A

, a second liquid reservoir


116


may optionally be provided with the above-described baby wipes warmer


110


. The second liquid reservoir


116


is primarily used to maintain the hydration of the sponge layer


112


and the baby wipes


12


. To achieve such purpose, a vertically mounted sponge wall


118


is included along an inner reservoir surface


120


of the second liquid reservoir


116


. The vertical sponge wall


118


is essentially used to absorb the necessary liquid from the second liquid reservoir


116


via at least one reservoir hole


122


extended therethrough. The absorbed liquid is then evaporated into the inside compartment


124


of the baby wipes warmer


110


which adds further moisture to the baby wipes


12


disposed therein. Simultaneously, because the vertical sponge wall


118


is disposed in abutting contact with the sponge layer


112


, the liquid drawn from the reservoir


116


by the sponge wall


118


can permeate to the sponge layer


112


. This helps to maintain the moisture. content of the sponge layer


112


.




The second liquid reservoir


116


includes an external viewing port


126


at the outer reservoir surface


128


. The external viewing port


126


lets a user see the level of liquid contained therein. If the liquid level is low, then the user may pour additional liquid either directly within the inside compartment


124


or the second liquid reservoir


116


.





FIG. 7

shows a baby wipes warmer


140


which is made in accordance with a fifth preferred embodiment of the present invention. This warmer


140


is substantially identical to the first embodied baby wipes warmer


10


except that its liquid tank assembly


142


is fabricated in the form of an elongated central channel and is embedded laterally along the interior compartment surface


144


. This elongated central channel serving as the liquid tank assembly


142


includes a sponge


146


within its liquid compartment

. The sponge


146


operates to draw the liquid


150


out of the adjacently located liquid reservoir


152


by capillary action. Similar to the tank assembly


32


of the first embodiment, its upper tank surface


154


includes a plurality of vapor holes


156


which allow the liquid


150


to evaporate therethrough.




The operation of the first embodied baby wipes warmer


10


is described herein which is simultaneously representative for operations of all the above embodied baby wipes warmers


70


,


90


,


110


,


140


. 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 and/or inside compartment (for the first, second, third and fifth embodiments) or the moisture content of the sponge layer (for the fourth 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.
