DETAILED DESCRIPTION OF THE INVENTION

(8) The present invention is directed to a potty training device 100 having a substantially flat configuration, comprising a bendable urine-deflector 3, a plurality of attachment tabs 1, a folding seam 2 positioned on the back side of the potty training device 100, and a means for attaching the potty training device 100 to the underside of a toilet seat 50. More specifically, the potty training device 100 is configured such that the folding seam 2 separates the potty training device 100 into a top portion comprising, a plurality of attachment tabs 1 and a bottom portion, comprising the urine deflector 3.

(9) The means for attaching the potty training device 100 to the underside of the toilet seat 50 allows the bendable urine-deflector 3 to be positioned in a curved configuration to block the opening 52 formed between the toilet seat 50 and the toilet bowl 51, to allow a front side surface of the bendable urine-deflector 3 to function as a urine-deflecting surface to deflect a urine stream directed towards the opening into the toilet bowl 51, as shown in FIG. 7.

(10) In its attached curved configuration, the front side urine deflecting surface of the bendable urine-deflector 3 faces to the rear of the toilet seat. The flexibility of the potty training device 100 allows for manual manipulation into various curvatures, so as to accommodate the shape of many different toilet seats.

(11) The urine-deflector 3 preferably has a rectangular configuration, as shown in FIGS. 1 and 2. The height of the urine-deflector 3 is defined as the length from the top edge to the bottom edge of the urine-deflector 3. The top edge of the urine-deflector 3 is in contact with the bottom edge of the folding seam 2. The width of the urine-deflector 3 is defined as the length between its left edge and right edge. The width of the urine-deflector 3 is greater than its height.

(12) The width of the urine-deflector 3 is selected to provide sufficient coverage for the variation in the lateral direction of a child's urine stream. While not intending to be limited to any particular width for the urine-deflector 3, preferred widths are from 6-9 inches. The height of urine-deflector 3 is selected to allow the urine-deflector 3 to completely block the opening formed between the underside of the toilet seat 50 and the top of the toilet bowl 51. While not intending to be limited to any particular height for urine-deflector 3, preferred heights range from 1-3 inches. In a particular embodiment of the invention, the urine-deflector 3 has a rectangular dimension of 6 inches by 3 inches or 6 inches by 1.5 inches.

(13) Additionally, the dimensions of the urine-deflector 3 are sufficient to avoid contact with the toilet bowl 51 when the toilet seat 50 is lifted to, or lowered from, a vertical position. Further, the potty training device 100 once attached, is not visible to the observer unless the toilet seat 50 is raised, is in an upright vertical position or is viewed from a position to the rear of the attachment point when the toilet seat 50 is down.

(14) The present invention is also directed to a potty training device 100 comprising a bendable urine-deflector 3, a plurality of attachment tabs 1, and an adhesive material 5 applied to each attachment tab 1, wherein the adhesive material 5 attaches the potty training device 100 to the underside of a toilet seat 50.

(15) The potty training device 100 of the present invention may comprise any number of attachment tabs 1. Depending on the size of the width of the urine-deflector 3, from 4-10 attachment tabs 1 are preferred. An odd number of attachment tabs 1 is particularly preferred, because the center attachment tab provides a visual reference point for centering the potty training device 100 at the attachment point on the underside of the toilet seat 50. Thus, in a particular embodiment of the invention, 5, 7 or 9 attachment tabs 1 are preferred. All attachment tabs 1 preferably have the same dimensions and are evenly distributed across the width of the urine-deflector 3.

(16) In order to attach the potty training device 100 to the underside of the toilet seat 50, an adhesive material 5 is applied on each attachment tab 1. The adhesive material 5 can be applied by any suitable means, for example, by layering, coating or printing, and the adhesive is, preferably, applied as a solid layer, although it is also possible to apply the adhesive in a pattern of discrete islands of adhesive, for example, in the form of dots or squares or other shapes, as is well known in the adhesive arts.

(17) The potty training device 100 is applied to the underside of the toilet seat 50 in a series of steps comprising: (i) folding the upper portion of the device 100, shown in FIGS. 1-3, along the folding seam 2, such that the angle between the top portion and the bottom portion on the back side of device 100 decrease to about 90 degrees, such that device 100 has an L-shaped configuration as shown in FIG. 4; (ii) manipulating the L-shaped device 100 into a curved configuration by bending the left and right edges of the urine-deflector 3 inward, such that the plurality of attachment tabs 1 separate, resulting in the curved configuration shown in FIG. 5; (iii) aligning the curved device 100 with the curvature of the underside of a toilet seat 50; and (iv) pressing the plurality of attachment tabs 1 against the underside of the toilet seat 50 in order to engage the adhesive material 5 on the surface of the attachment tabs 1, such that the adhesive material 5 secures the device 100 to the underside of the toilet seat 50.

(18) While any means for attaching the potty training device 100 to the underside of a toilet seat 50 can be used, an adhesive material 5 is preferred. The adhesive material 5 is a preferably pressure-sensitive adhesive strip (such as, for example, “double sided tape”) or pressure-sensitive resin that is applied to each attachment tab 1, and once applied to the underside of the toilet seat 50, is preferably strong enough to hold the potty training device 100 in place until physically removed by the consumer and not damage the finish of the toilet seat 50 during removal.

(19) The adhesive material 5 is preferably water-resistant and non-porous. The adhesive material 5 is also preferably applied to the plurality of attachment tabs in a thin layer coating or as a thin sheet, where an adhesive strip is used. While not compromising the ability of the adhesive material 5 to hold the potty training device 100 in place, the application of the adhesive material 5 to the plurality of attachment tabs 1 should be as thin as possible, so as to not create large gaps between the potty training device 100 and the underside of the toilet seat 50. Such large gaps could allow urine to accumulate therein and contribute to excessive odor development. While it is understood that regardless of how thin the adhesive material 5 applied to the plurality of attachment tabs 1 is, small gaps may likely exist, and urine may find its way into such gaps by capillary action. The benefit of having small gaps, however, is that use of a cleaning solvent such as alcohol, will also enter the small gaps by capillary action and thereby reduce or eliminate odor development. Therefore, any gaps that are formed by the presence of the adhesive material 5 on the plurality of attachment tabs 1 should be as small as possible to aid in the ability to clean the potty training device 100.

(20) In order to assist with removal of potty training device 100 from the toilet seat, in another embodiment of the invention, each individual attachment tab 1 may comprise a release tab 6, as shown in FIGS. 2 and 5. The release tabs 6 allow the consumer to pull the potty training device 100 away from the toilet seat 50, without touching the urine-deflector 3. The release tabs 6 comprise a section of the attachment tabs 1, which does not contain any adhesive material 5, thereby allowing the consumer to, for example, grasp a non-adhesive containing section of the attachment tab 1 between their thumb and index finger, and pull the attachment tab 1 away from the toilet seat. By way of example, as shown in the drawings, the release tabs 6 are engaged by bending or folding down a small section of the attachment tab 1 along a bending or folding seam 6a.

(21) While the release tabs 6 shown in the drawings represent one possible configuration for this element of the invention, other configurations for this element of the invention are also possible. Suitable configurations for the release tabs 6 are those that will allow the consumer to easily grasp a portion of the attachment tab 1 with their thumb and index finger and pull successive attachment tabs 1 away from the toilet seat 50 thereby removing the potty training device 100. Regardless of the configuration of this embodiment, the adhesive material 5 is not applied to the release tab 6. Once removed from the toilet seat 50, the potty training device 100 may be discarded in the trash.

(22) In another embodiment of the present invention, the potty training device 100 is made from a flexible, water-resistant and preferably non-porous material. Any material having these characteristics is suitable for the invention. In a particular embodiment of the invention, the potty training device 100 is made from a rubber or plastic resin material, wherein a plastic resin material is particularly preferred. While any plastic resin material having the above characteristics can be used, plastic resin materials may be selected from, but not limited to: polyethylene, polypropylene, polystyrene, polyvinylchloride (PVC) and polytetrafluoroethylene (PTFE).

(23) Other types of plastic resin materials that are suitable for making the potty training device 100 of the present invention include thermoplastic elastomer (TPE) materials. TPE materials are particularly preferred as they are well suited for use in injection molding processes, produce products that are flexible, strong and tear resistant, have a rubbery feel and texture, and are soft to the touch. Examples of TPE material suitable for making the potty training device of the present invention include, but are not limited to: ONFLEX, DYNAFLEX, KRATON, ARNTITEL, ENGAGE, HYTREL, DRYFLEX and MEDIPRENE. DYNAFLEX is a preferred TPE material for making the potty training device 100 of the present invention.

(24) To further assist in maintaining the sanitary condition of the potty training device 100 of the present invention, may also be treated with any compound that inhibits the formation of odor, bacteria, mold or other urine associated growth. The potty training device 100 may also be a medical grade type material, such as a medical grade plastic for example, that is also resistant to the formation of odor, bacteria, mold or other urine associated growth, provided that the selected material has the desired flexibility characteristics previously described.

(25) The invention has been described in terms of illustrative embodiments. It will be understood by those of ordinary skill in the art that various modifications and changes may be made to these embodiments without departing from the spirit or scope of the invention. It is intended that the invention not be limited in any manner by the embodiments shown and described herein.
