[0033] In the shown embodiment, the front panel 11 is coextensive and attached with the base panel. The front panel 11 and base panel may be formed from a single ply or multiple plies of paper. In one embodiment, the front panel 11 is made from paper material in a single ply configuration. The front panel 11 includes textured elements 23 that are configured for scrubbing debris from surfaces. The textured elements 23 may include alternating or consecutive series of ridges and recessed channels. In the shown embodiment, the textured elements 23 are ridges that are positioned towards a center region of the cleaning pad 10. In this way, as the cleaning pad 10 is manipulated across a surface, the textured elements 23 and the front panel 11 frictionally engage with debris to remove the debris therefrom. In an alternative embodiment, the textured elements 23 are disposed on the reinforcing layer 13.
[0034] In one embodiment, the front panel 11 and the base panel are removably joined along a perimeter of the cleaning pad 10. In another embodiment, a fragrance agent is impregnated within the front panel 11, the reinforcing layer 13, and/or the base panel. The fragrance includes, without limitation, fragrances of perfume, clove, flowers, peppermint, spearmint, fruit flavor, apple, lemon, cinnamon, grape, vanilla, and chocolate.
[0035] In the shown embodiment, the reinforcing layer 13 is positioned between the base panel and the front panel 11. The reinforcing layer 13 provides structural rigidity so as to allow the general shape of the cleaning pad 10 to be retained upon scrubbing or other frictional engage with a surface. In the shown embodiment, the reinforcing layer 13 is a planar conical member that is tapered from the first end 14 to the second end 15.
[0036] Referring to
[0037] Referring to
[0038] In the illustrated embodiment, the solution package 18 is positioned between the reinforcing layer 13 and the front panel 11. In this way, a user can release the cleaning agent by pressing the base panel 12 towards the front panel 11, whereby the pressure causes the solution package 18 to rupture and release the cleaning agent on the front panel 11. In an alternative embodiment, the solution package 18 may be integrated into the reinforcing layer 13, disposed lateral the reinforcing layer 13, or the like, as to ensure that the solution can permeate through the front panel.
[0039] In one exemplary use, a cleaning pad 10 is selected and handled by a user. The user actuates a pull tab 19 that is operably connected to the solution package 18, wherein the cleaning agent is released therefrom. A user may further press the base panel 12 towards the front panel 11 so as to discharge the cleaning agent through the apertures 20 of the front panel 11. The reinforcing layer 13 with textured elements is selectively and frictionally engaged with a desired surface, such as wiping after defecation. The cleaning pad 10 is discarded into a toilet bowl, whereby the cleaning pad 10 dissolves or otherwise breaks apart upon therein. In an alternative embodiment, the textured elements 23 are disposed on the front panel 11.
[0040] Referring to
[0041] In the shown embodiment, the second end is curved between the tab and recesses of the first cleaning pad 10a and the first end of a second cleaning pad 10b. Thus, the transverse perforated edge 21 formed between adjacent cleaning pads 10a-10b and 10b-10c corresponds to the shape of the ends of the adjacent cleaning pads.
[0042] Specifically referring to
[0043] Referring now to
[0044] The first end 130 forms an inner section 140 of the roll 110. The inner section 140 comprises several layers of plurality of sheets 120 of the first end 130 bonded together by an adhesive 190 to provide rigidity to the inner section 140. This provides the roll 110 with structural integrity similar to that provided by a traditional cardboard tube. In some embodiments, the inner section 140 further comprises a corrugated inner surface 240. The corrugated inner surface 240 is formed as the plurality of sheets 120 are layered together and is configured to provide additional strength and rigidity to the inner section 140.
[0045] In the illustrated embodiment, the inner section 140 forms an axial passageway 160 extending between a first side 170 and a second side 180 of the roll 110. The axial passageway 160 is configured to receive a rod (shown in
[0046] In the illustrated embodiment, the inner section 140 is bonded by an adhesive 190. The adhesive 190 is configured to penetrate through several layers of the plurality of sheets 120. These bonded layers stiffen the inner section 140 to provide structural integrity to the roll 110 such that the roll 110 does not collapse under its own weight. In some embodiments, the adhesive 190 is configured to penetrate four to six layers of the plurality of sheets 120. In another embodiment, the adhesive 190 is configured to increase the rigidity of the inner section 140 to at least twice that of the second end 150. The adhesive 190 is further configured to degrade when in contact with water. In this way, the inner section 140 loses its rigid properties, regaining the physical properties of the plurality of sheets 120. This allows the inner center 140 to be disposed of similarly to the plurality of sheets 120, such as via flushing into a toilet. In some embodiments, the adhesive 190 comprises polyvinyl alcohol.
[0047] In some embodiments, the adhesive 190 further comprises a fragrance agent configured to emit a scent when exposed to air or water. In this way, when the roll 110 is rotated about the rod, the fragrance agent is activated by the increased airflow through the axial passageway 160, causing a pleasant scent to be emitted from the inner section 140. Furthermore, when the user disposes of the inner section 140 in a toilet, the fragrance agent is activated when it contacts the water, releasing a pleasant scent. In another embodiment, the adhesive 190 further comprises a non-chemical disinfectant configured to sanitize a container having a volume of water therein, such as a toilet bowl, after a predetermined amount of time in contact with the water. In some embodiments, the amount of time required to sanitize the container is greater than that required to degrade the adhesive 190. In this way, the disinfectant provides an efficient and simple means of cleaning the container.
[0048] Referring now to
[0049] To increase the thickness d2 of the inner section 140, additional layers of tissue and adhesive is applied to the plurality of sheets during the manufacturing process, such that the adhesive penetrates further layers of the plurality of sheets. As the adhesive cures, the rigidity and strength of the inner section 140 increases. In this way, the inner section 140 can support increased weight and stress without failing. This process can be repeated as desired to achieve the desired rigidity as required by the desired final width dl.
[0050] Referring to
[0051] Referring now to
[0052] Referring now to
[0053] In some embodiments, the low-friction tube comprises a tubular platen having a plurality of recesses thereon, wherein each of the plurality of recesses comprises an aperture therein. In this embodiment, air is circulated through the tubular platen such that negative pressure is generated at the apertures, thereby securing the plurality of sheets to the tubular platen for rolling. Additionally, as the plurality of sheets are layered on top of each other, the plurality of recesses form a void space between layers such that a corrugated texture is formed in the inner section of the roll. This corrugated pattern adds structural integrity to the roll.
[0054] The method of manufacturing the paper roll further comprises determining the desired thickness of the roll 204. At this time, a user determines 204 the overall desired size and thickness of the roll to be manufactured. The larger the roll, the greater the stresses placed on the inner section of the roll, and therefore, the greater the required strength and rigidity of the inner section to resist those stresses.
[0055] An adhesive is then applied to the roll to form an inner section 206. The adhesive is applied 206 during the winding 202 process, such that multiple layers of the plurality of sheets are bonded together. In some embodiments, the adhesive is configured to penetrate and bond 4-6 adjacent layers of the plurality of sheets. If the inner section requires increased strength and rigidity to counteract the weight of the roll, additional layers of adhesive can be applied 206 such that the thickness of the inner section is increased. In this way, the thickness of the inner section can be increased by an additional 4-6 layers of the plurality of sheets each time a new layer of adhesive is applied 206.
[0056] Once the desired thickness of the inner section is achieved, the adhesive is then cured 208. In one embodiment, curing the adhesive 208 comprises allowing the inner section to dry over time. In some embodiments, the temperature of the air circulated through the tubular platen is configured to decrease the curing 208 time of the adhesive applied. In this way, the curing 208 process can be completed more efficiently.
[0057] The winding 202 stops once the desired size of roll is reached. At this point, the curing 208 process is complete and the low-friction tube is removed 210 from the roll. In some embodiments, once removed from the low-friction tube, the method 201 further comprises cutting the roll to a desired length 212. In another embodiment, the method 201 further comprises packaging the roll for distribution 214.

[0061] In one embodiment, the method further comprises moistening the pliable substrate; positioning the pliable substrate within a mold to be coextensive with a molding surface of the mold.
[0062] In one embodiment, the method further comprises positioning the substrate onto a mandrel, wherein the rigid object maintains an exterior shape of the mandrel.
[0063] In one embodiment, the method further comprises positioning the pliable substrate between an inner mold and an outer mold, wherein the inner mold mates with the outer mold defining an interior adapted to receive the pliable substrate, wherein the adhesive is applied between coextensive layers of the pliable substrate; wherein the pliable substrate is pressed so as to form the rigid object having a shape of the interior.
[0064] In one embodiment, the method further comprises positioning the pliable substrate between an inner mold and an outer mold, wherein the inner mold mates with the outer mold defining an interior adapted to receive the pliable substrate, wherein the polyvinyl alcohol adhesive is applied between coextensive layers of the pliable substrate; wherein the pliable substrate is pressed so as to form the rigid object having a shape of the interior.
[0065] In one embodiment, the method further comprises blowing the pliable substrate onto a mold.
[0066] In one embodiment, the method further comprises applying the pliable substrate to an interior of a mold, the pliable substrate further includes fiber or cellulose, wherein the mold is rotated causing the pliable substrate to form the rigid object having a hollow interior volume; warming the mold to release the rigid object therefrom.
