Description




FIELD OF INVENTION




This invention relates generally to liquid dispensing devices, and more particularly, to liquid soap dispensing devices.




BACKGROUND OF THE INVENTION




Various liquid dispensing devices are known in the art. For example, commonly known dispensers are those used for distributing soap (e.g., hand soap) in public restrooms. The dispensers offer the benefits of convenience of use, easy refilling, refillable or disposable containers, and the like.




One example of common soap dispensers is the disposable pump and container system which generally comprises a plastic bottle with a pump which screws into a cap fitted to the bottle. Generally, these units are disposed of once empty. However, in some cases, the bottles may be refilled. Unfortunately, however, these dispensers are susceptible to being knocked over, stolen, or lost because, in general, they merely sit on countertops and in wash basin areas. Further, the containers tend to be of smaller and/or limited capacity.




Another common dispenser is the wall-mounted dispenser which is intended to provide a greater degree of security and reliability for public restrooms. Generally, this type of dispensing apparatus comprises a housing which is mounted on the wall of the restroom. The housing is open and inside a disposable or refillable container of liquid soap is placed within the housing. The housing is closed and a pumping means is used for distributing the soap to the user.




These types of dispensers are not without their drawbacks either. For example, they can be messy. That is, many dispensers have pump mechanisms which are awkward for the user. When a lever is pulled the soap is dispensed into the user's hand. However, this can cause soap to drip on the lever and other structures of the soap dispenser. Likewise, other push button type dispensers consist of elongated pumping members which also may become covered with liquid soap and may be prone to breaking. Still further, with many of these soap dispensers, sanitation can be a problem. That is, because the pumping mechanisms and ejection nozzles are integrated with the dispenser itself, they must be cleaned or replaced. Because they are integrated with the dispenser itself, it is often not easy to replace the pumping mechanism.




With existing soap dispensers it is also common for janitorial services to dispose of refill bottles before they are completely empty. For example, many janitorial services have prescheduled times that they check and clean the soap dispensers and the restrooms they are located in. If a soap dispenser bottle is nearly empty, often, to ensure that the dispenser does not run out of soap before the person refilling the dispenser returns, they will simply throw out the bottle, regardless of how much soap is left, and replace it with a full bottle. Thus, the potential for wasting soap is high.




Further, it is not uncommon to place soap bottle refills within soap dispenser housings which are not intended to fit within the housing being used. This leads to an insecure fit within the housing, potentially causing problems with dispensing, closing the housing, and wobble of the bottle within the housing.




Thus, improved soap dispenser housing units are desirable. In particular, units which are more sanitary, aesthetically pleasing, do no suffer from premature disposal of the refill bottles, and prevent wobble within the housing are desirable.




SUMMARY OF THE INVENTION




In accordance with various aspects of the present invention, a liquid dispensing apparatus having improved sanitary, aesthetics and stabilizing aspects is provided. For example, in accordance with one aspect of the present invention, liquid dispensing apparatus comprises a dispensing housing designed to contain a soap filled bottle. Depending on particular configurations, the housing may be designed as an open or closed system. In any case, the housing preferably has a sleek, streamlined design with a dispensing button which tends to have a rounded appearance that accents the shape of the remainder of the housing. Similarly, the housing has various aspects tending to create a symmetry between various views of the dispenser. In accordance with various other aspects of the present invention, within the housing is a stabilization system which prevents bottles which are not designed to engage housing from being inserted into housing. In addition to (or alternatively) housing may have support structure which allows the soap bottle to rest within housing with less of a propensity to wobble.

DETAILED DESCRIPTION




The following descriptions are of exemplary embodiments of the invention only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description is intended to provide a convenient illustration for implementing various embodiments of the invention. As will become apparent, various changes may be made in the function and arrangement of the elements described herein without departing from the spirit and scope of the invention. For example, though not specifically described, many shapes and orientations of the housing and refill bottle and alternative dispensing and pumping mechanisms should be understood to fall within the scope of the present invention.




In general, the present invention comprises a liquid dispensing unit


10


with a backing


11


, a cover


12


, and a bottle


30


. Dispensing unit


10


is preferably comprised of a substantially rigid plastic such as high density polyethylene (“HDPE”), but any other suitable material rigid, semi-rigid or even flexible material may be used.




As can be seen with reference to

FIGS. 1 and 2

, in one exemplary embodiment, cover


12


is releasably attached to backing


11


. As should be apparent, various configurations for attaching backing


11


and cover


12


may be employed, and generally allow for cover


12


to be opened such that a cavity


13


is accessible. In this embodiment, cover


12


is hingedly connected to backing


11


by hinges


14


so that cover


12


may be pivotally opened. Of course, in accordance with various alternative embodiments of the invention, cover


12


may be completely detachable, slidably releasable, or the like. Optionally, cover


12


or part of cover


12


may be comprised of a clear or translucent material to enable the user to view the contents of dispenser


10


, for example, to aid in determining whether the unit needs to be refilled.




Further still, as mentioned above, in accordance with various embodiments of the present invention, cover


12


preferably has an aesthetically pleasing, sleek, design. For example, in the various embodiments described herein, cover


12


has a substantially longer vertical length than its width. Additionally, the corners of the housing, as well as the edges, tend to be of a rounded nature. Similarly, the dispensing button (which is configured to operate various pumping mechanisms) has similarly rounded features which tend to flow with remainder of cover


12


. Thus, symmetry of the various features and views of unit


10


is created. Still further, for aesthetic reasons, the dispensing button and cover


12


(and likewise various other components of dispenser


10


) may optionally be of varying colors.




In accordance with another aspect of dispenser


10


, a locking mechanism is provided to secure cover


12


and back


11


in a closed position. Generally, any means of securing cover


12


and back


11


may be used, including snaps, adhesives, threadable connections and the like. In the presently described embodiment, locking mechanism comprises a reception


15


and corresponding teeth


16


. In this embodiment, teeth


16


are located on cover


12


and reception


15


is located on backing


11


, though it should be apparent the locations may be reversed. Teeth


16


preferably engage reception


15


in a snap fit manner to secure cover


12


and back


11


. Preferably, back


11


has a keyhole


17


for disengaging cover


12


and back


11


. In the present embodiment, to disengage locking mechanism, a key


60


is inserted into key holes


17


. The key suitably extends teeth


16


away from reception


15


so that cover


12


may be pivoted away from back


11


.




In accordance with another aspect of the present invention, a stabilizing mechanism is provided. Stabilizing mechanism suitably comprises any structure which prevents bottles of the wrong size to be placed in dispenser


10


and/or suitably provides support to the bottles inserted into dispenser


10


aiding in preventing movement of the bottle once inserted into dispenser


10


(rotation or “wobble”). For example, in accordance with one exemplary embodiment, stabilizing mechanism


40


comprises a projection


41


and a depression


50


. In the present exemplary embodiment, and with reference to

FIGS. 2

,


4


and


5


, projection


41


is a structure integrated into backing


11


, and depression


50


is a cavity integrated into bottle


30


which corresponds to projection


41


. Thus, projection


41


and depression


50


engage when bottle


30


is inserted into dispenser


10


.




Optionally, projection


41


may further comprise an anti-rotation protrusion


40




a


which aids in preventing rotational movement of bottle


30


within dispenser


10


. For example,

FIGS. 2 and 4

illustrate an exemplary embodiment of protrusion


40




a


configured as a notch-like projection. Similarly, depression


50


may further comprise an anti-rotation indention


50




a


which aids in preventing rotational movement of bottle


30


within dispenser


10


. For example,

FIG. 5

illustrates an exemplary embodiment of indention


50




a


configured as a notch-like depression which substantially corresponds to protrusion


40




a.






Of course, it should be apparent that in alternative embodiments, varying numbers and configurations of projections and depressions


41


,


50


may be used. For example, projection


41


and depression


50


may take on varying shapes so that bottle


30


cannot rotate within housing and likewise to correspond particular bottles


30


to particular dispensers


10


. Similarly, the shape of projection/depression


41


,


50


may indicate the manufacture of dispenser


10


. Further, projection


41


can be located on bottle


30


, and depression


50


can be located on the housing including, for example, backing


11


and cover


12


.




Stabilization system may also comprise (or alternatively comprise) support structure for supporting bottle


30


within dispenser


10


. For example, on back plate


11


, support structure


18


is provided so that a liquid dispensing bottle can be placed in cavity


13


such that bottle


30


is supported within cavity


13


. In the presently described embodiment, support structure


18


is provided on backing


11


to support bottle


30


once it is placed within cavity


13


of dispenser


10


. In the embodiment of

FIG. 2

, support structure


18


suitably comprises a plate with a neck depression


19


configured to surround the neck of bottle


30


such that bottle


30


is secured within cavity


13


. In the present embodiment, in a system where soap is distributed to the user directly from bottle


30


or a “closed system,” support structure


18


is located proximate to the lower portion of cavity


13


near the base of unit


10


.




With reference to

FIG. 2

, in accordance with the present exemplary embodiment, support structure


18


for a closed liquid dispensing system comprises a rigid shelf-like structure projecting from back plate


11


. Of course, in accordance with alternative embodiments, support structure


18


may comprise any alternative structure which suitably provides support to bottle


30


when placed in cavity


13


. For example, multiple projections which need not be integrated with back plate


11


may be used. Likewise, support straps which encircle the bottle, snap in locking mechanisms and other support structure such as substantially vertical members which support the sides of the bottle may be used.




Generally, with reference to

FIG. 3

, in a closed system, bottle


30


contains its own dispensing nozzle


62


for regulating disbursement of the contents of bottle


30


. As mentioned above, a closed system allows for disbursement of the liquid in the bottle to be dispensed directly from bottle


30


to the user. When a pumping mechanism


25


integrated with dispenser


10


is activated, pumping mechanism


25


interacts with nozzle


62


to dispense soap to the user. For example, in this closed system embodiment, when pumping mechanism


25


is pressed inward by the user, a pumping member


25




a


extends a collar


63


on bottle


30


in a downward direction to dispense soap to the user. When deactivated, collar


63


returns to its original position and soap is not dispensed.




Now, in accordance with but one alternative embodiment of the present invention, dispenser


10


comprises a system where the soap leaves bottle


30


and is transferred to a compartment of unit


10


prior to disbursement of the user or an “open system.” With combined reference to

FIGS. 3 and 4

, bottle


30


generally contains a neck with a nozzle configured to engage an open system pumping mechanism


20


. In the open dispenser


10


, the liquid to be dispensed leaves the bottle and fills a containment unit


21


prior to disbursement to the user. With reference now to

FIG. 4

, an exemplary open system is illustrated. In accordance with this embodiment, a reservoir


21


is provided. In this embodiment, reservoir


21


is suitably integrated with support structure


18


and pumping mechanism


20


. When dispenser


10


is open, bottle


30


can be placed upon support structure


18


located directly above reservoir


21


. An opening


22


is provided on reservoir


21


. Opening


22


suitably comprises a piercing mechanism


23


surrounded by a plurality of holes to allow soap to drain into reservoir


21


. In accordance with the present embodiment, piercing mechanism


23


suitably pierces the foil over the opening of bottle


30


(to prevent leakage prior to use) so that soap may be dispensed from bottle


30


. The holes suitably allow soap to be dispensed into reservoir


21


and/or likewise allow air to return to bottle


30


as soap is dispensed. Thus, when bottle


30


is placed in cavity


13


and foil is pierced by piercing mechanism


23


, soap flows into reservoir


21


. Thus, during use, a user operates pumping mechanism


20


which pumps the liquid (soap) directly from reservoir


21


to the user.




Thus, it should be apparent that many alterations of the dispenser embodiments described herein may be made. For example, as mentioned above, open and closed systems may be interchanged. That is, reservoir


21


may be suitably configured to fit the structure which comprises a closed system. Further, many drawbacks of the prior art are solved. For example, with reference to the closed system, pumping mechanisms and nozzles do not become messy or unsanitary.




Lastly, various aspects of the invention have been described in illustrative embodiments. Of course, many combinations and modifications of the above-described structures, arrangements, proportions, elements, materials and components, used in the practice of the invention, in addition to those not specifically described, may be varied and particularly adapted to specific environments and operating requirements without departing from those principles.
