ABSTRACT:
FIELD OF THE INVENTION
This invention relates to soap dispensers and in particular soap dispensers with covers that can be readily changed to display printed matter or to complement the surrounding decoration.
BACKGROUND OF THE INVENTION
Soap dispensers are well known and are primarily used in industrial and commercial settings. Initially the design of soap dispensers was functional. Thereafter more attention was paid to the aesthetic appearance of the soap dispensers. Increasingly, particularly for commercial setting, the aesthetic appearance of the soap dispenser is very important. Therefore it is important to have a soap dispenser that is both functional and aesthetically pleasing.
To that end, Scott™ introduced a soap dispenser with a central band that can swing open and that has a plasticized sheet inserted therebehind. Although this soap dispenser allows the users to modify the appearance somewhat, changing the colour of the band does not materially change the overall look of the soap dispenser. Further, the swinging band loosely fits into the cover and therefore water or cleaning fluid can easily migrate behind the band during cleaning. Therefore any sheet that is inserted behind the band must be plasticized or coated so that it cannot be ruined by water and the like.
It is noted that increasingly, advertising is found in many public places. Often in washrooms there is advertising in the toilet stalls and other places. Heretofore, the soap dispensers have not been used to display advertising. Accordingly, an opportunity in regard to advertising has been missed.
Accordingly, it would be advantageous to provide a soap dispenser that includes a cover that can be easily changed to co-ordinate with the decor. Further it would be advantageous to provide a soap dispenser that includes a place to display advertising and wherein that advertising may be something easily printed on any type of sheet.
SUMMARY OF THE INVENTION
The soap dispenser of the present invention is used in association with a pump operated bottle of liquid soap. The soap dispenser includes a back plate, a cover, a pump mechanism and an outer shell. The cover is releasably attached to the back plate. The cover and the back plate define a volute therebetween. The pump operated bottle is positioned in the volute and the pump mechanism is operably connected to the bottle. There is a means to operate the pump mechanism to dispense soap. The outer shell extends over a portion of the cover and is releasably attached thereto. The outer shell can be interchanged with a plurality of similar outer shells. There is a seal between the outer shell and the cover. The outer shell may have a window formed therein and a printed sheet or advertising sheet may be positioned behind the window. The outer shell may have a logo or other design thereon.
Further features of the invention will be described or will become apparent in the course of the following detailed description.
