Referring now to FIG. 1, there is shown an exploded view of an embodiment of the soap sheet dispenser. The soap sheet dispenser 11 comprises a housing 12 having a rear wall (as shown in FIG. 4, 13) and a perimeter sidewall 14 extending therefrom, thereby defining an interior volume. The interior volume is dimensioned to removably receive a dispenser cartridge 18 therein. A door 17 is hingedly affixed to the perimeter sidewall 14 and is selectively movable between an open position and a closed position, wherein the closed position the door 17 encloses the interior volume. In the illustrated embodiment, the door 17 further comprises a transparent panel 27 therein, wherein the transparent panel 27 provides a view into the interior volume. In this manner, the user can readily visualize whether the dispenser cartridge 18 needs to be refilled with additional single use soap sheets 19.
The dispenser cartridge 18 is removably securable within the housing 12, such that the user can remove the dispenser cartridge 18 for refilling when the plurality of sheets 19 are depleted. The plurality of sheets 19 are stored within the dispenser cartridge 18 in a stacked configuration to facilitate dispensing a single sheet at a time. The plurality of sheets 19 are impregnated with a cleansing material, such as soap or hand sanitizer, to allow a user to readily clean their hands. In some embodiments, the plurality of sheets 19 comprise a stabilized cleansing material in a sheet format such that the plurality of sheets 19 are dissolvable upon contact with water. In this way, waste can be minimized. In alternate embodiments, the soap impregnated within the plurality of sheets 19 is dissolvable within water, such as a dry soap activated by contact with water, such that the shelf life of the plurality of sheets 19 is maximized. In this way, the dispenser cartridge 18 does not require frequent refilling absent regular use. In the illustrated embodiment, the dispenser cartridge 18 further comprises a slot 21 disposed through a lower end 22 thereof, wherein the slot 21 is dimensioned receive a single sheet of the plurality of sheets 19 therethrough. In the shown embodiment, a window 28 is disposed through a front side (as shown in FIG. 3, 29) of the dispenser cartridge 18, wherein the window provides access to the interior of the dispenser cartridge 18. In some embodiments, the window 28 is utilized to gauge the number of sheets of the plurality of sheets 19 remaining within the dispenser cartridge 18, whereas, in alternate embodiments, the user can refill the dispenser cartridge 18 via inserting the plurality of sheets 19 through the window 28. In such embodiments, the window 28 is dimensioned to have a width greater than the plurality of sheets 19. However, in other embodiments, the width of the window 28 is less than that of the plurality of sheets 19 to prevent the sheets from exiting the dispenser cartridge 18 therethrough during use. In such embodiments, the upper end of the dispenser cartridge 18 may be removably affixed to the dispenser cartridge 18 to provide an access point for refilling the dispenser cartridge 18.
Referring now to FIG. 2, there is shown a close-up view of the gap of an embodiment of the soap sheet dispenser. In the illustrated embodiment, the door 17 is in the closed position, defining a gap 24 between the perimeter sidewall 14 of the housing and a lower edge 25 of the door 17. In this manner, upon dispensing a sheet 19 from the slot within the dispenser cartridge, the sheet 19 is guided downward upon contact with an interior of the door 17 and exits the housing through the gap 24. In this manner, the user can readily access the sheet 19 upon actuation of the dispenser cartridge. In some embodiments, the gap 24 is disposed through the lower edge 25 of the door 17, such that the gap 24 is aligned with the slot of the dispenser cartridge. In such embodiments, the sheet 19 immediately exists through the gap 24 upon being dispensed through the slot. Furthermore, in the illustrated embodiment, a motion sensor 23 is disposed on a front side of the door 17, wherein the motion sensor 23 is operably connected to the dispenser cartridge. In this manner, upon actuation of the motion sensor 23, such as by a user waving a hand in front of the motion sensor 23, the dispenser cartridge dispenses a sheet 19 therefrom. In this manner, user contact with the soap sheet dispenser is minimized, thereby reducing the risk of contamination, or spread of pathogens caused due to user operation. The motion sensor 23 can be further calibrated to operate upon detection of motion within a threshold distance to reduce the risk of unintended activation. In alternate embodiments, the housing further comprises a manual control thereon, the manual control configured to instruct the dispenser cartridge to dispense a sheet 19 upon actuation of the manual control.
Referring now to FIG. 3, there is shown a cross-sectional view of the dispenser cartridge of an embodiment of the soap sheet dispenser. The dispenser cartridge 18 further comprises a dispensing mechanism therein. In the shown embodiment, the dispenser mechanism comprises a motor 33 operably connected to the motion sensor, such that upon actuation of the motion sensor, the motor 33 is activated to rotate at least one roller 34 disposed within a lower end of the dispenser cartridge 18. Upon rotation of the roller 34, a lowermost sheet of the plurality of sheets 19 is dispensed through the slot 21. In such embodiments, the roller 34 comprise a height equivalent to a distance between a floor of the dispenser cartridge 18 and the slot 21. In the shown embodiment, the plurality of sheets 19 each comprise multiple panels folded over each other defining a series of interwoven adjacent sheets. In this manner, upon dispensing of a single sheet of the plurality of sheets 19, an adjacent sheet is primed for dispensing through the slot 21.
In the shown embodiment, the dispenser cartridge 18 further comprises a spring mechanism having a plate 31 affixed to one or more springs 32 attached to an upper end of the dispenser cartridge 18. The plate 31 is configured to provide even pressure to an uppermost sheet of the plurality of sheets 19 to drive the plurality of sheets 19 towards the rollers 34 and the slot 21. In this manner, the plate 31 exerts sufficient pressure against the plurality of sheets 19 to ensure that the lowermost sheet is engaged with the roller 34. Once the plurality of sheets 19 are depleted, the user can insert additional sheets 19 via the window 28 within the front side 29 of the dispenser cartridge 18. Alternatively, in some embodiments, the upper end of the dispenser cartridge 18 can be removed to insert additional sheets 19 into the interior of the dispenser cartridge 18.
Referring now to FIG. 4, there is shown a side view of an embodiment of the soap sheet dispenser. In the illustrated embodiment, at least one fastener 35 is disposed on the rear wall 13 of the housing 12, wherein the fasteners 35 are configured to removably secure the housing 12 to a support surface, such as a wall. In some embodiments, the fasteners 35 are removably securable to the rear wall 13, such that the fasteners 35 can be removed when the housing 12 is being used in a free-standing manner, such as on a countertop or stand. In such embodiments, the fasteners 35 may be removably securable via friction fit or rotationally securable within an aperture via a tab extending from a portion of the fastener. In the illustrated embodiment, the fasteners 35 comprise suction cups, however, in alternate embodiments, alternate fasteners 35 are contemplated, such as hook and loop, bolts, screws, and the like. Furthermore, in the shown embodiment, the housing 12 includes a lock 26 thereon, wherein the lock 26 is configured to retain the door 17 in the closed position. In this manner, only authorized individuals can open the housing 12 to remove or refill the dispenser cartridge.
In one use, the housing 12 can be installed on a wall surface via the fasteners 35 or rested on a countertop or stand. A user can wave a hand in front of the motion sensor or actuate a manual control to actuate the motor within the dispenser cartridge to dispense a sheet of the plurality of sheets through the slot and gap. Once the sheet is retrieved, the user can spread the soap impregnated within the plurality of sheets over their hands before rinsing their hands in a nearby sink. Alternatively, in embodiments utilizing an impregnated hand sanitizer, the user can avoid utilizing a sink entirely. In this way, the user can minimize the amount of contact with communal objects, thereby reducing the risk of contracting various pathogens. Once finished, the user can throw the depleted sheet away, or in some embodiments, the sheet is configured to dissolve when contacting water to minimize waste. When the dispenser cartridge is depleted, the user can open the housing 12 and refill the dispenser cartridge with additional sheets.
It is therefore submitted that the instant invention has been shown and described in various embodiments.
