Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001]The present application claims priority to Provisional Application Ser. No. 60/988,361, entitled "Protective Cover for Diaper Changing Station", to Paszotta, filed on Nov. 15, 2007.

FIELD OF THE INVENTION

[0002]The present invention relates to disposable covers. In particular, the invention relates to a disposable cover that is removably securable to a diaper changing station and used to protect a child from unsanitary public surfaces during the process of changing the child's diaper. The disposable cover also provides a salubrious means of disposing of the used cover and the soiled diaper.

BACKGROUND OF THE INVENTION

[0003]Diaper changing stations located in public restrooms assist parents by providing a flat, horizontal, sturdy surface on which to place a child and change a diaper. These public diaper changing stations typically are mounted to a wall. When in the stored position, the flat surface is generally parallel to the wall. When in use, the pivotally connected flat surface rotates down to a horizontal position and becomes perpendicular to a now exposed vertical surface. Often, after use, the previous user has not properly cleaned the surfaces after changing a child's soiled diaper. This can result in viruses, bacteria, and other contaminants being left on the surfaces. These contaminants give rise to the possibility of infecting subsequent users. The leftover contaminants also promote the spread of common colds as well as infectious diseases to not only the child but also to the parent and other restroom users. Some parents resort to using paper towels, toilet paper, or changing pads to insulate their child from the horizontal surface during the diaper changing process. These items typically do not cover the entire horizontal surface and also may be difficult to keep in place under a wiggling or floundering child. Often the vertical surface is left uncovered and exposed to contamination. Both surfaces of the diaper changing station may also be contaminated if the parent does not properly secure the contents of the diaper or the used diaper itself for proper disposal.

[0004]Typical of the prior art is U.S. Patent Application Publication No. 2007/0256244 to Ashley. Ashley discloses a disposable diaper changing cover for use with a diaper changing table that is commonly found in public restrooms. The cover can be stretched over the flat surface of the table. An elastic band around the edges of the cover is used to removably secure the cover to the table. The elastic band can extend around all four edges of the cover or a combination thereof. In one embodiment, the cover contains two adhesive sections that are used to help secure the cover to the table. The adhesive sections contact the protruding horizontal surface of the table. However, the vertical surface of the table is left exposed and the diaper itself is left to be disposed of independently.

[0005]U.S. Patent Application Publication No. 2007/0240261 to Yazarlo-Stahl et al. discloses a disposable cover for seat cushions, mattresses, and changing tables. The cover is comprised of a liquid-receiving layer, an absorption body, and a backing layer. The cover further contains a securing flap that is used to securely close the rolled up cover after use. The first end of the securing flap is permanently affixed to the cover. The second end of the securing flap contains an adhesive. When the cover is in use, the second end of the securing flap is releasably adhered to a portion of the pad to a specialized surface that resists bonding with the adhesive. Once the cover is rolled, the second end of the securing flap is then removed from the specialized surface. To secure the cover closed, the second end of the securing flap is secured to a portion of the cover that does not contain a specialized surface and therefore bonds with the adhesive. However, when used for a diaper changing station, the vertical surface remains exposed and the pad itself is bulky and space consuming. Further, the play allowed by the second end of the securing flap requires the effectiveness of the attachment of the flap to the cover.

[0006]Therefore a need exists for a disposable cover for a diaper changing station that covers both surfaces of the changing station, is easily affixed to the changing station, stays in place during use and provides a convenient means to properly secure and dispose of the used diaper after removal from the child.

SUMMARY OF INVENTION

[0007]The preferred embodiment of the present invention provides a disposable cover for a diaper changing station commonly found in public restrooms. The invention provides a one-piece sanitary covering for both the flat horizontal surface that supports the child and the vertical surface exposed when the changing station is in use. The cover is flexible enough and compactable enough to be easily stored in a typical bag or purse.

[0008]Accordingly, the preferred embodiment of the present invention is comprised of a generally rectangular shaped thin, flexible material of sufficient size to cover both exposed surfaces of a typical diaper changing station. Three of the four edges of the cover contain elastic material. The fourth edge includes two double sided adhesive tabs extending perpendicular from the edge. A portion of each tab is permanently affixed to the cover. The remainder of each tab contains an adhesive coating on both sides. The adhesive coating on both sides of each tab are covered by a removable strip.

[0009]In use, the cover is placed on the changing station with the edge containing the tabs aligned with the vertical surface of the changing station. The cover is secured to the changing station by first wrapping the elastic edges around the changing station's protruding horizontal surface. The removable strips on each of the tabs adjacent the changing station's vertical surface are removed. Once the adhesive portions of the tabs are exposed, the tabs are pressed against the changing station's vertical surface.

[0010]To remove the cover from the changing station, the adhesive tabs are removed from the vertical surface of the changing station. The elastic edges are then unwrapped from the changing station's horizontal surface. The cover is wrapped inward to contain contaminants from the diaper changing process within the cover and isolate them from contact with external surfaces. The removable strips that cover the remaining adhesive portion of the tabs are removed. The newly exposed adhesive portions of the tabs are used to keep the cover securely closed. Additionally, the used diaper can be wrapped up in the cover as well for sanitary disposal. The cover and the diaper are disposed of in a receptacle located in the restroom.

[0011]Those skilled in the art will further appreciate the above-mentioned features and advantages of the invention together with other important aspects upon reading the detailed description that follows in conjunction with the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016]In the descriptions that follow, like parts are marked throughout the specification and drawings with the same numerals, respectively. The drawing figures are not necessarily drawn to scale and certain figures may be shown in exaggerated or generalized form in the interest of clarity and conciseness.

[0017]FIGS. 1 and 2 show disposable cover 100. The preferred embodiment of disposable cover 100 is generally rectangular in shape. An alternate embodiment could be square shaped or oval shaped. An additional alternate embodiment could have flaps extending from two opposite edges generally forming a T shape. The criticality of the size and shape being that it is large enough and shaped appropriately to completely cover a typical diaper changing station as shown in FIG. 1. In the preferred embodiment, disposable cover 100 is a thin, lightweight plastic sheet. Disposable cover 100 in a preferred embodiment is transparent. In an alternate embodiment, disposable cover 100 is made of durable, lightweight paper having a wax or plastic surface adhered to at least one side. In another preferred embodiment, the cover can be impregnated with or covered in a non-volatile disinfectant on one or both sides that is capable of sterilizing the changing table. In another preferred embodiment, the cover can be impregnated with or covered in a chemical with a pleasant smelling scent.

[0018]In still a further embodiment, the cover may be an opaque white plastic impregnated with a temperature sensitive pigment. Examples of heat sensitive pigments are shown in Pressure and Temperature Sensitive Paints by Tianshu Liu and John P. Sullivan (Springer 2004), incorporated herein by referenced. In this preferred embodiment the temperature of the child can be ascertained after changing by observing the cover where the child was in contact with it. The cover may include printed legend 101 correlating the colors to an appropriate range of temperatures. If an elevated temperature is indicated, appropriate health care can be administered to the child. Disposable cover 100 is easily compacted and before unfolding for use, is easily transportable in a typical purse, bag, or pocket.

[0019]Disposable cover 100 has top side 126 and bottom side 128. Disposable cover 100 further includes diametrically opposed edges 110, 112, 114, and 116. Edges 112, 114, and 116 contain elastic 134 along their peripheries. In the preferred embodiment, elastic 134 is a ribbon of elastic material sewn into disposable cover 100 at the edges. In the preferred embodiment, the entire length of edge 114 and approximately half the lengths of edges 112 and 116 include elastic 134. In alternate embodiments, elastic 134 can extend through the entire length of all edges 110, 112, 114, and 116 or just the entire length of edges 112, 114, and 116. Edge 110 further includes tabs 130 and 132. Tabs 130 and 132 extend approximately perpendicularly from and overlap edge 110. Tabs 130 and 132 are permanently affixed to disposable cover 100. The lateral location of tabs 130 and 132 is generally equidistant between both tabs and edges 112 and 116.

[0020]Diaper changing station 102 is comprised of housing 108 and table 106. Housing 108 is generally configured as a three sided box and is commonly attached to a vertical surface such as wall 104. Table 106 is pivotally attached to housing 108 at pivot point 118. When in a stored position, table 106 is rotated upwards to where it's generally parallel with wall 104 and is fully contained in housing 108. When in use, table 106 is rotated downward so that table 106 extends perpendicular from wall 104. Table 106 includes horizontal surface 122. When table 106 is rotated downward and extends perpendicularly from wall 104, vertical surface 120 of housing 108 is exposed.

[0021]FIG. 3 shows the layers of tab 130. Tab 132 is structurally identical to tab 130. Tab 130 includes base layer 314 having ends 320 and 322. Tab 130 is permanently affixed to top side 126 of disposable cover 100 at end 322. Adhesive layer 312 is adjacent one side of base layer 314 at end 320. Adhesive layer 310 is adjacent the opposite side of base layer 314 at end 320. Adhesive layers 310 and 312 have a releasable tack strength capable of securing disposable cover 100 to diaper changing station 102 but also easily removable without leaving a residue. Removable strip 308 is adjacent adhesive layer 312 and completely covers adhesive layer 312. Removable strip 306 is adjacent adhesive layer 310 and completely covers adhesive layer 310. Removable strips 306 and 308 can be easily removed from adhesive layers 310 and 312 respectively without removing the adhesives from base layer 314.

[0022]In use, disposable cover 100 completely covers both horizontal surface 122 and vertical surface 120 of diaper changing station 102 to provide a clean, sanitary surface on which to change the diaper of a child. Table 106 is rotated downward from a stored position within housing 108 until table 106 is generally parallel with the floor. Disposable cover 100 is secured to diaper changing station 102 by first wrapping edge 114 over the leading edge of table 106. Edges 112 and 116 of disposable cover 100 are wrapped around the lateral edges of table 106. Elastic 134 contained in edges 112, 114, and 116 keeps disposable cover 100 from slipping off horizontal surface 122. Disposable cover 100 is pulled taut so that bottom side 128 is adjacent horizontal surface 122 and also adjacent vertical surface 120. Removable strip 306 is peeled away from both tabs 130 and 132 exposing adhesive layer 310. Tabs 130 and 132 are secured to vertical surface 120 by pressing the now exposed adhesive layers on each tab onto vertical surface 120. Adhesive layer 310 on each tab keeps disposable cover 100 from slipping off vertical surface 120.

[0023]After completing the diaper change and moving the child off the diaper changing station, disposable cover 100 is removed from diaper changing station 102 by first untucking edges 112, 114, and 116 from underneath table 106. Edges 112, 114, and 116 are folded upward and inward and disposable cover 100 is rolled up into a tube or ball shape towards edge 110. Tabs 130 and 132 are peeled from vertical surface 120. Removable strip 308 is peeled away from both tabs 130 and 132 exposing adhesive layer 312. Edge 110 is folded over the tube or ball and adhesive layer 312 on both tabs 130 and 132 is used to prevent disposable cover 100 from unfolding and keep disposable cover 100 rolled up. Additionally, the soiled diaper may also be rolled up in disposable cover 100.

[0024]It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
