Abstract
The present invention is a liner which may readily be utilized in a toilet receptacle such as a child's potty or a bedpan. The liner comprises a flexible sheet fabricated from biodegradable material. The sheet is liquid impermeable and capable of retaining human excrement. The central portion of the flexible sheet is adapted to assume a bag-like configuration so as to conform with the inner receptacle surfaces of a standard potty chair or bedpan. Unique attachment tabs are disposed on the perimeter of the sheet so that the liner may be adhesively secured in an efficient manner to the surfaces of the potty seat or bedpan. The design and arrangement of the attachment tabs are such that the tabs may be utilized to adhesively seal the liner after use whereby the sealed bag may be disposed of in a proper manner.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention generally relates to waste containment devices. More specifically, the present invention is drawn to a disposable liner for use with a potty or bed pan.




2. Description of Related Art




Aside from changing diapers, the most odious task in child rearing is that of emptying, cleaning and sterilizing the potty. The smell of the disinfectant cleaner makes this an unenviable assignment.




A similar scenario occurs when it is necessary to care for a disabled adult (perhaps a family member) who requires the use of a bedpan. Handling excrement from adults greatly increases the chances of transmitting infectious bacteria, especially in home environments and other situations where bedpan sterilization equipment may not be available or adequate. Providing a disposable, effective, easy-to-seal liner for potty or bedpan use, which liner is disposable-glove friendly, would certainly be a welcome addition to the art.




The prior art is replete with liners adapted for use with potties. For example, U.S. Pat. No. Des. 354,342 (Marshall-Smith) and U.S. Pat. No. Des. 402,739 (McClements) show designs for disposable potty liners. The patents do not discuss attachment structure for the liners.




U.S. Pat. No. 4,759,086 (Booth-Cox) shows structure wherein a receptacle is removably attached to the rim of a potty seat. The entire receptacle is removed for disposal.




U.S. Pat. No. 6,115,855 (Lorenzo) discloses a liner for a child's potty, wherein the liner is provided with a hole for insertion of a potty handle therethrough. The liner is relatively complicated to secure on the potty and could not be effectively used in a conventional bedpan.




U.S. Pat. No. 3,936,890 (Oberstein), U.S. Pat. No. 4,011,606 (Scrafield et al.) and U.S. Pat. No. 4,343,053 (O'Connor) show disposable bedpan liners. The attachment means of the instant liners would not be readily adaptable for potty seat use.




U.S. Pat. No. 4,882,794 (Stewart, III) shows a liner adapted for use for a bedpan or a potty seat. The liner has no means for sealing after use.




U.S. Pat. No. 3,495,278 (Peters) shows a bag toilet wherein the toilet seat is rotated to seal the bag after use.




None of the above inventions and patents, taken either singly or in combination, is seen to disclose a liner for use with a potty or a bedpan as will subsequently be described and claimed in the instant invention.




SUMMARY OF THE INVENTION




The present invention is drawn to a liner which may readily be utilized in a child's potty or a bedpan. The liner comprises a, flexible sheet fabricated from biodegradable material. The sheet is liquid impermeable and capable of retaining human excrement. The central portion of the flexible sheet is adapted to assume a bag configuration so as to conform with the inner receptacle surfaces of a standard potty chair or bedpan. Unique attachment tabs are disposed on the periphery of the sheet so that the liner may be adhesively secured and easily removed to the surfaces of the potty seat or bedpan in an efficient manner. The design and arrangement of the attachment tabs are such that the tabs may be utilized to adhesively seal the liner after use so that the sealed bag may be disposed of in a proper manner (trash, bio-hazard bin, incinerator, etc.).




As contemplated, the liner will be fabricated in two sizes (potty and bedpan). The liner may also be scented for deodorizing purposes if desired.




Accordingly, it is a principal object of the invention to provide a disposable liner for a bed pan or child's potty.




It is another object of the invention to provide a disposable liner for a bedpan or child's potty, which liner can be easily attached to the potty or bedpan.




It is a further object of the invention to provide a disposable liner for a bedpan or child's potty, which liner can be easily and efficiently sealed after use and which liner is, disposable-glove user friendly.




Still another object of the invention is to provide a disposable liner for a bedpan or child's potty, which liner is fabricated from biodegradable material.




It is an object of the invention to provide improved elements and arrangements thereof in a disposable liner for the purposes described which are inexpensive, dependable and fully effective in accomplishing their intended purposes.




These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Attention is first directed to

FIGS. 1-3

of the drawings wherein the potty liner of the instant invention is generally indicated at


10


. Liner


10


is fabricated from a thin, flexible, liquid impermeable, biodegradable material (paper or plastic). The material should be strong enough to hold human excrement without rupturing. Liner


10


includes a central portion


12


of bag-like configuration. Portion


12


is adapted to conform to the inner surfaces of the receptacle of a potty chair P (shown in phantom lines). Plural tab members


14


are positioned on the liner and evenly spaced therearound so as to contact and attach to the upper surface of potty chair. Adhesive is applied to the under surfaces of tab members


14


to achieve the attachment. Any suitable, commercially available, disposable-glove friendly adhesive may be applied to the liner. Conventional release liners (not shown) can be utilized to prevent adhesive exposure until use. Non-adhesive tabs


14




b


(shown only in

FIG. 1

) are attached to the peripheral edges of tabs


14


to enhance manipulation when wearing disposable gloves.




As contemplated, liner


10


may be individually wrapped and packaged for sale. As shown in

FIG. 2

, an individual liner is packaged in a wrapping


16


, which wrapping is closed by an adhesive tab


16




a


, which tab is provided with a non-adhesive, fold-over end to enhance manipulation. A protective cover


18


having a pull tab


18




a


is positioned to overlie the liner.




A decided advantage of the present invention is the utilization of the tab members


14


, protective cover


18


and wrapping


16


to seal the liner for disposal. In a first embodiment (

FIG. 4

) after removal from the potty chair P, tabs


14


are simply folded over to close the liner bag


12


. The adhesive on the underside of tabs


14


effectively seals the tabs in the closed position.





FIG. 5

is illustrative of a second embodiment wherein in addition to the underside, adhesive is applied to the topside of two adjacently positioned tabs


14


. Release liners


14




a


are provided to prevent adhesive exposure until use. Having adhesive on both sides will allow a user to secure the tabs together to close and seal the wastes in the liner. Alternatively, as shown in

FIG. 6

, protective cover


18


can be reused and attached to the tabs to further seal the wastes in the liner.




In

FIG. 7

the liner is secured in wrapping


16


. Adhesive tab


16




a


is reused to fasten the ends of wrapping


16


.





FIGS. 8 and 9

illustrate an embodiment wherein a disposable liner generally indicated at


20


is adapted to a conventional bed pan


22


(shown in phantom lines). As with the potty liner above, liner


20


is fabricated from a thin, flexible, liquid impermeable, biodegradable material (paper or plastic). The material should be strong enough to hold human excrement without rupturing. Liner


20


includes a central portion


24


of bag-like configuration. Portion


24


is adapted to conform to the inner surfaces of the bed pan


22


. Four tabs


26


, having adhesive under surfaces, are positioned around the liner and are adapted to be disposed on and adhere to the upper surfaces of bed pan


22


. Like potty liner


10


, liner


20


also has two adjacent tabs provided with adhesive on their upper surfaces. The edges of tabs


26


are provided with non-adhesive easy-grip pull tabs


26




a


so that the liner may be easily removed from the bed pan when using disposable gloves.

FIG. 9

is illustrative of liner


20


in a before use condition. Bed pan liner


20


will be packaged and sealed after use in a manner similar to that of potty liner


10


.
