The attached figures are provided as non-limiting examples for providing an enabling description of the method and system claimed. Attention is called to the fact, however, that the appended drawings illustrate only typical embodiments of this invention and are therefore not to be considered as limiting of its scope.

Well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

DETAILED DESCRIPTION

[0024] Having summarized various aspects of the present disclosure, reference will now be made in detail to that which is illustrated in the drawings. While the disclosure will be described in connection with these drawings, there is no intent to limit it to the embodiment or embodiments disclosed herein. Rather, the intent is to cover all alternatives, modifications and equivalents included within the spirit and scope of the disclosure as defined by the appended claims.

[0025] With reference to FIG. 1, a plan view exposing an underside of one embodiment of the hygienic toilet seat and lid assembly 10 is shown in order to generally illustrate sealing the assembly 10 to block bodily waste and associated contaminants contemplated by this disclosure. More particularly, the assembly 10 may comprise an annular toilet seat 12, such as any of those toilet seats commonly known in the art for supporting a user thereon and receiving biological waste therethrough, and a lid 14, hingedly attached to the seat 12 along corresponding rear edges 16, for covering the seat 12 when not in use. The open, center portion of the annular toilet seat 12 may then be fully sealed off, or plugged, by a male protrusion 18 that extends downwardly into the opening, which is here defined by an inner edge 20 of the seat 12 but otherwise obscured due to the presence of the male protrusion 18.

[0026] Turning to FIG. 2, elements comprising the toilet seat and lid assembly 10 may be viewed in an exploded configuration and in combination with a toilet 30 for additional clarity. The annular seat 12, for instance, may be defined by a supportive upper surface 22, upon which a user may sit, and a lower surface 24 which rests on top of and is pivotally securable to a rim 32 around a toilet bowl 34. Further defining the annular toilet seat 12, the supportive upper surface 22 and lower surface 24 may be spaced apart by an inner side portion 26 which defines the opening 28 in the seat 12 for admitting biological waste to enter the toilet bowl 34 for disposal, and an outer side portion 29.

[0027] Additionally, the lid 14, hingedly connected to the seat 12, may comprise an underside 42 configured to matedly seal the opening 34 in the seat 12 and minimize the amount of water, bacteria, bodily waste, and potential contaminants expelled from the bowl 34 into the surrounding area and onto surrounding surfaces when flushed. In particular, the underside 42 of the lid 14 comprises in some embodiments, a concave channel 44 sized to overlap with and closely receive the supportive upper surface 22 of the annular toilet seat 12. The channel 44 may be defined by an outer edge 46 of the lid 14 spaced apart from the aforementioned male protrusion 18. Providing a channel in this manner may insure a close seal to prevent debris, biological waste, contaminants, etc. from exiting a flushing toilet bowl 32 via any possible gaps which may exist between the edge 46 of the lid 14 and side portion 29 of the seat. However, it is also contemplated that the alternative to a channel 44 formed in the underside 42 of the lid 14, the underside 42 of the lid 14 may alternatively be flat, excepting extension of the male protrusion 18, so that the underside 22 of the lid 14 may contiguously rest along the upper supportive surface 28 of the annular seat 12, while the male protrusion 18 closely mates with the opening 34 in the seat 12.

[0028] Regardless of the particular shape of the underside 42 of the toilet seat 14, it is contemplated that the male protrusion 18 may comprise a side portion 48 formed to extend into the opening 28 defined by the seat 12 and, when engaged in the closed position, also be contiguous with the inner side portion 26 of the seat 12. This may be seen, for example, with reference to FIGS. 3 and 4, which illustrate a closed-off seal 36 where the underside 42 of the lid 14 and supportive surface 22 of the seat 12 contiguously rest against one another. Of course, one skilled in the art will recognize that the word “seal” is herein used to mean, generally, to shut, block, obscure, cover, plug or otherwise close off access to the contents of the toilet bowl 32, and forming an air tight seal is not necessary to practice the invention. One skilled in the art will also recognize that when disposed over a toilet bowl, sealing, or plugging, any openings in the toilet seat, and also any gaps that typically persist between toilet seats and lids and even between toilet seats and toilet rims in this manner, even if not air tight, will minimize or even wholly prevent biological waste and potentially harmful contaminants contained therein from being projected into nearby spaces and onto nearby surfaces when the toilet is flushed.

[0029] Returning to FIG. 2, to operate, a user may hingedly pivot the lid 14 into an upward, open position to expose the opening 28 defined by the annular seat 12 and interior of the toilet bowl 34. If desired, a user may also hingedly pivot the toilet seat 12 into an upward position to reveal the rim 32 defining an upper edge of the toilet bowl 34. Then, after use but before flushing the toilet, the user may hingedly pivot any open portions of the assembly 10 into a closed position, so that the male protrusion 18 is mated with the opening 28 in the annular toilet seat 12 to seal or plug the assembly 10 so that aerosolized waste, water, and particulate are prevented from exiting the bowl 34 through the space that typically persists between such parts.

[0030] It is further envisioned that one embodiment of the of the male protrusion 18 may comprise a low profile such that the lower surface 52 would rest above the supportive surface 22 when the assembly 10 is in the closed position. In this exemplary embodiment, the male protrusion 18 may comprise a ridge which extends below the supportive surface 22 while the the lower surface 52 of the male protrusion 18 remains above it.

[0031] With reference to the perspective view according to an embodiment of the hygienic toilet seat and lid assembly in FIG. 3, a lower surface 52 may further define the male protrusion 18 and may be flat. Providing a flat lower surface 52 may inhibit growth and propagation of any bacteria collected on the male protrusion 18 and also make cleaning the lid 12 easy, as it has a smooth surface area, however, other shapes and textures are contemplated as well.

[0032] In some embodiments, the lower surface 52 of the male protrusion 18 may extend below the toilet seat to further obscure any potential space, though microscopic, that may be left between the protrusion 18 and inner edge 20 of the annular seat 12. In other embodiments, the lower surface 52 of the male protrusion 18 may extend only as far as the lower surface 24 of the annular seat 12 to define a smooth surface when the assembly is closed. In still other embodiments, the lower surface 52 of the seat may extend to some distance that extends, when the assembly 10 is closed, below the supportive surface 22 but above the lower surface 24 of the seat so that at least some depth defined by the side portion 29 of the seat 12 is plugged. Thus, the particular height of the side portion 48 of the male protrusion 18 is not determinative so long as it is able to plug or otherwise close off the opening 28 defined by the annular seat 12.

[0033] With reference to FIG. 4, an additional ridge 54 may optionally be formed along a portion of, or even the entirety of, the male protrusion 18. Such ridge 54 may extend beyond the lower surface of the seat 12 to prevent undesirable material from entering any space between the contiguous side portions of the seat 12 and lid 14.

[0034] Other configurations are contemplated for sealing, or plugging, the toilet seat 12 in addition to easing use of the assembly 10. As one non limiting example and with reference again to FIG. 2, a front portion of the side 48 of the male protrusion 18, may be angled inward by some amount to easy opening and closing the lid 14 while avoiding frictional or forcible interference with corresponding segments of the side portion 26 of the seat 12. As another example, the lid 14, channel 44, and even male protrusion 18 may be formed as a single, integrated piece in order to avoid cracks, seams, and crevices which might harbor bacteria, to ease application of cleaning solutions to the lid 14, and even to improve the aesthetic appearance of the lid 14. Of course, one skilled in the art will recognize that the foregoing are offered by way of example only, and not of limitation.

[0035] It should be emphasized that the above-described embodiments are merely examples of possible implementations. Many variations and modifications may be made to the above-described embodiments without departing from the principles of the present disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
