US20090158525A1 - Disposable cover for diaper changing station and method of use - Google Patents

Abstract

A disposable cover for use with a public diaper changing station provides a sanitary barrier between the child and the horizontal and vertical surfaces of the diaper changing station. Three edges of the disposable cover include an elastic band for securing the cover around the horizontal surface of the diaper changing station. Another edge has two tabs permanently affixed to the cover. The tabs are double sided adhesive for attaching to the vertical surface of the diaper changing station and for securing the cover tightly to itself after use for sanitary disposal. The cover safeguards both the horizontal surface and the vertical surface of the diaper changing station to insulate the child and parent from possible contact with these surfaces during use. After use, the cover folds up on itself containing any contaminants and curtailing the spread of bacteria.

Description

CROSS REFERENCE TO RELATED APPLICATIONS
• This application is a Continuation-In-Part claiming priority benefit from U.S. patent application Ser. No. 12/291,933, entitled “Disposable Cover for Diaper Changing Station and Method of Use” filed on Nov. 14, 2008 which claims priority from U.S. Provisional Application Ser. No. 60/988,361, entitled “Protective Cover for Diaper Changing Station” filed on Nov. 15, 2007.
FIELD OF THE INVENTION
• 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
• 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.
• 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.
• 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.
• 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
• 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.
• 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.
• An alternate preferred embodiment is made up of three different sized rectangular sections. A one by two ratio section connected by a small rectangular region to a larger two by four ratio section. The two by four section has three edges that include elastic and the one by two section includes two double-sided adhesive tabs extending perpendicular from an edge. The adhesive coating on both sides of each tab are covered by a removable strip.
• 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.
• 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.
• 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.
