Description

DISCUSSION OF RELATED ART

Seat covers are generally publicly available in most public bathrooms. The seat cover has been in use at least since U.S. Pat. No. 4,887,321 to MacLean issued Dec. 19, 1989 provides a history of seat covers, the disclosure of which is incorporated herein by reference.
“Many such toilet seat covers have been proposed in the past. In U.S. Pat. No. 787,357 issued Apr. 18, 1905 to G. H. Davis, such a seat cover is provided which is in the form a single sheet having a impositively secured central portion to provide a central opening and which is formed and folded to provide a single entity independent of all other sheets. Such articles may then be vended in suitable machines furnished for that purpose or in packets of convenient numbers for travelling kits and the like.
U.S. Pat. No. 1,138,440 patented May 4, 1915 by E. L. Bainbridge-Bell provides a sanitary shield in the form of a sheet of suitable material weakened adjacent one end on two quadrant lines jointly forming a broken semi-circle curved toward the center of the sheet. The sheet is similarly weakened adjacent the other end on quadrant lines jointly forming a broken semi-circle curved toward the center of the sheet. The sheet is finally weakened on a median line from a point adjacent one semi-circular line to a point adjacent the center of the sheet, and is similarly weakened on a median line from a point adjacent the other semi-circular line to a point adjacent the center of the sheet. This provides an opening bounded for four downwardly projecting shields.
U.S. Pat. No. 1,155,260 patented Sep. 28, 1915 by H. F. W. Meyer provides a sanitary seat cover comprising a thin sheet of paper of oval contour having an oblong central opening. The material is accordion folded around two sides and one end on predetermined score lines. The opposite end of the material is folded on predetermined score lines and forms a housing receiving the sides and first end in folded position. The device is adapted to assume a flat condition upon removal of the sides and end from within the housing.
U.S. Pat. No. 1,268,024 patented May 28, 1918 by I. Levin provides a toilet seat protector comprising an annulus of creped paper having a waxed margin and formed with perforations adjacent to its outer edge. The annulus has longitudinal, transverse and diagonal fold lines.
U.S. Pat. No. 1,377,791 patented May 10, 1921 by K. Putchner provides a commode seat cover consisting of a sheet of thin paper having two longitudinally extending cuts, approximately parallel to each other, and a transverse cut disposed between but not intersecting the parallel cuts. The transverse cut is so located that when longitudinal strain is placed upon the sheet of paper across the transverse cut, the paper will tear transversely from the transverse cut, in opposite directions to the longitudinal cuts. This provides an opening having forward and rear flap. The sheet is interfolded to be disposed in five layers.
U.S. Pat. No. 1,509,868 patented Sep. 30, 1924 by T. P. Harris provides a sanitary covering for seats which has broad flaps positioned to hang one at the front and one at the back of the cover, and thus to depend into the closet bowl, provides means for preventing the cover from slipping off the toilet seat and also means for preventing the cover from twisting around the seat due to the fact that the flaps are positioned at the ends of the longest dimension of the opening in the cover. The flap has a particular shape i.e. it broadens out immediately from its point of support to provide a very broad protecting surface both front and rear, thus effectively guarding the user against contact with the seat or with the parts of the bowl therebeneath. Because of the width of the depending flap the splashing of water when the bowl may be flushed is reduced to a minimum. This particular broadened flap is struck from the material of the sheet and extends substantially the full width of the opening when the flap and sheet lie in the same plane.
U.S. Pat. No. 1,835,787 patented Dec. 8, 1931 by M. H. Kniseley provides a sanitary closed seat cover comprising a rectangular cover piece with fold thereacross to form treble thickness. A flap is cut through the center thereof and across the treble thickness fold. The increased length is adapted to extend into the water of the toilet bowl, the folds at each side of the flap being cemented.
U.S. Pat. No. 1,961,195 issued Jun. 5, 1934 to G. Carruthers provides a protective toilet seat cover of the type having a semi-detached pattern cut therein to provide a displaceable opening forming portion. The sheet is folded continuously from one end to the other in a common direction, as distinguished from the back and forth or zig-zag type of fold. The outer folds are coiled around and enclose the inner folds and fold edges. In this way, the folds retain the patterned portion and cut edges from exposure.
U.S. Pat. No. 2,266,990 issued Dec. 23, 1941 to P. F. Rea provides toilet seat covers which are in the form of prefolding a sheet of paper, having discontinuous incisions across the fold. The edges and ends of the folded sheet are trimmed.
U.S. Pat. No. 2,742,650 issued Apr. 24, 1956 to M. Mohun provides a foldable auxiliary toilet seat comprised of forward and rearward pairs of oppositely disposed flat, relatively stiff members. The ends of the pairs of members are disposed substantially along the longitudinal fold line of the seat. Hinge means interconnect the members of each pair. Special means are provided which are adapted to resist a collapsing folding action of the seat about the longitudinal fold line when the seat is positioned for use. Such means are in the form of spaced notches formed in the ends of the members of each pair, such notches defining finger-like elements therebetween. The finger-like elements of each member extend through the notches of the other member into overlapping relation with the other member.
U.S. Pat. No. 4,050,105 issued Sep. 17, 1977 to L. S. Marceaux provides a disposable toilet seat cover for a toilet seat surface area for accommodating a user. The toilet seat cover has a front crotch, a back part, an inner side and an outer side providing a smooth contour and shape, and a bottom surface area opposite to the surface area of the toilet seat. The disposable toilet seat cover has the contour and shape of the top contour of a toilet seat but is of larger dimensions so that it ranges over the outer side of the toilet seat. The cover is made of paper flushable in a toilet. The cover has an inner center flap and an outer circumference consisting solely of paper and extends beyond and inwardly and outwardly of the toilet seat opening and fastened at the front central part of the toilet seat. The fastening is by means of a pair of spaced flaps consisting solely of paper positioned at the back part of the toilet seat, the flaps having self-adhesive tabs for removably affixing the cover to the bottom surface of the toilet seat.

Each sheet of the package has parallel incisions and aligned perforations extending entirely across the sheet in one direction. The sheet is folded lengthwise into overlying strips along the lines of incisions and perforations. Perforations extend entirely across the sheet, normal to the incisions. The strips are folded one over the other and are thereby adapted to be torn apart on the normal perforations into sections of toilet paper of standard size. The incisions further divide the sheet into a U-shaped perimetric portion and an interior flap.
Canadian Patent No. 335,427 issued Sep. 3, 1933 provides a folded toilet sheet in the form of a sheet of paper having a pattern cut through the surface. The toilet sheet is folded in a plurality of parallel folds to place the cuts in each successive fold in divergent relation to the adjacent fold and finally to enclose the cut portions.
Canadian Pat. No. 525,797 issued Jun. 5, 1956 to I. B. Woodford provides an improvement in a cover for a toilet seat. It includes a fabric blank shaped to conform to the outline of the toilet seat and has an opening disposed substantially centrally thereof. Binding tapes are provided having one edge positioned upon one face of the blank adjacent each of the bounding edge of the blank and of the bounding wall of the opening and are secured thereto. The portion of the binding tape which is contiguous to one secured edge is turned about the adjacent bounding edge of the blank, and the bounding wall of the opening has the portion adjacent its other edge disposed in confronting relation with respect to the other face of the blank. The other edge of each of the tapes is secured to the blank, thereby to form a pair of oval sheaths. A resilient element is fixedly positioned within each of the sheaths and extends therearound. This element urges the peripheral portions of the blank into engagement with the toilet seat.
Canadian Patent No. 663,767 issued May 28, 1967 to R. Cluxton provides a removable cover for toilet seats in the form of an envelope cover comprising a fabric blank. The fabric blank has a central opening approximating the shape of the opening in the toilet seat. A binding is stitched to the outer peripheral edge of the fabric blank, the binding being formed of an elastic material stretched lengthwise about the outer peripheral edge of the fabric blank and stitched thereto while in its stretched condition. The binding on its contracted state thereby draws the blank into an envelope fitting snugly on the toilet seat surface and about its peripheral edge.

Marceaux, the disclosure of which is incorporated herein by reference, the disposible toilet seat cover has flaps having self-adhesive tabs for removably affixing the cover to the bottom surface of the toilet seat. The present invention seeks to improve the functionality of the prior art.

SUMMARY OF THE INVENTION

A seat cover comprises a main sheet connected to a central sheet at a connection. The main sheet is connected to the connection as a single sheet, and the main sheet is sized for fitting over and on top of a standard toilet seat. Modules are bonded to the main sheet. The modules have a module upper wall and a module lower wall. Each module upper wall is laminate bonded to each module lower wall. A cavity is formed between each module upper wall and each module lower wall. Upper surfaces of each of the modules are bonded to a lower surface of the main sheet. An adhesive is encapsulated within the module. A module score on the module lower wall releases adhesive when down pressure is applied to the module.
The adhesive can lightly adhere the main sheet to a seat by spreading in a capillary manner after release from the module score. The adhesive comprises a substantial amount of alcohol content preferably over 25% by weight. The adhesive loses adhesion after evaporation. The modules are bonded on the main sheet in rear sheet positions and optionally in front sheet positions. The adhesive may include an epoxy, silicone or glue. The adhesive may include tea tree oil, lavender oil or orange oil. The adhesive may include a starch thickener.
The present invention includes a main sheet that has a partial detachment area of a central sheet connected to the main sheet at a connection. The main sheet is connected to the connection as a single sheet. The main sheet is designed for fitting over and on top of a seat. The seat is typically foldable and has an upright position and a deployed position.
Disposed upon the main sheet are a plurality of modules that are bonded to the main sheet. The upper surface of the module upper wall is bonded to the lower surface of the main sheet. The modules include an adhesive encapsulated within the module. The modules have a laminate construction including a module upper wall laminated to a module lower wall. On the module lower wall a module score is a scored portion on the module lower wall that releases the adhesive when down pressure is applied to the module such as digit.
The modules are bonded on the main sheet in rear sheet positions and front sheet positions. The rear sheet positions correspond with rear seat positions. The front sheet positions correspond with front seat positions. By including modules in the rear portion or in the front portion, the main sheet is adhered to the seat accordingly. Preferably, a pair of modules is disposed in rear corners of the main sheet in rear sheet positions for attachment to rear seat positions. Optionally, a pair of modules is disposed in front corners of the main sheet in front sheet positions, for attachment to front seat positions. Also, more than a pair of modules can be disposed in the rear corners of the main sheet in rear sheet positions.
The adhesive used can include a small amount of an epoxy, silicone or glue such as jade adhesive (R). The adhesive also preferably includes a natural oil fragrance such as a tea tree oil, lavender oil or orange oil that can lightly adhere the main sheet to the seat by spreading in a capillary manner after release from the module score. The adhesive may further include a non-acid PVA or a wheat or Belgian rice starch or Lascaux Acrylic adhesive cellugel for thickening of the adhesive composition. The adhesive has a fragrance component and has a substantial amount of alcohol content so that it is volatile for rapid evaporation.
The amount of the, adhesive is predetermined so that the adhesive quickly loses stickiness over time because of rapid evaporation, such that there is no stain or mark on the seat. It is preferred that the adhesive loses stickiness after about minutes. After losing stickiness, the sheet may be flushed easily without tearing the adhered portion from the main portion. The sheets can be stored in a dispenser in a stacked configuration.
