Abstract:
A disposable self-contained fluid dispenser that can be easily mounted to a wall or toilet. The dispenser has a hinged integral fluid container (formed as a lever) and has a pump laterally extended from the fluid container. The fluid container is hinged to a back plate and a hood covers the top of the extended pump. The top edge of the back plate is hinged to the rear edge of the hood and the front of the hood is hinged to contact the compressible end of the pump. The three hinge points form a triangle. When the user presses the fluid container (lever) or applies downward pressure to the extended front end of the hood, the geometry of the triangle is altered thereby compressing the piston of the pump and causing fluid to be dispensed.

FIELD OF THE INVENTION 
     The present document relates to the filed of fluid dispensers for sanitization and cleaning purposes. 
     BACKGROUND 
     This section is intended to introduce the reader to aspects of art that may be related to various aspects of the present invention, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present invention. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art. 
     Fluid dispensers are a common method of dispensing a variety of products for general cleaning in spray and liquid form. This invention relates to dispensers that dispense fluids for body or hand use as well as dispensers for the moistening of tissue, either wall mounted or attached to a fixture such as a commode. 
     Many wall-mounted dispensers utilize replaceable containers of fluid in permanent housings such as U.S. Pat. No. 8,336,740 to Dassen. This type of dispenser is primarily for commercial installation as the expense and complexity of maintenance make this type of dispenser unsuitable for general home use in the bath or shower. 
     Dispensers that are attachable to a commode or fixture and provide a means of moistening tissue are described in U.S. Pat. No. 4,798,312 by Scheiber and also in U.S. Pat. No. 5,887,759 by Ayigbe. These types of dispensers are difficult to attach to many bathroom fixtures and when they are used on an applicable fixture, the proximity of the dispenser to the tissue makes their use difficult. 
     Dispensers directly attachable to a commode for body cleaning or for the moistening of tissue such as U.S. Pat. No. 7,162,754 by Haile, Jr. or U.S. Pat. No. 6,675,405 by Harm, utilize water from the house as a cleansing fluid. Installation and maintenance, unsightly appearance and sanitation are concerns as well as being difficult to use. 
     The need exists for a self-contained fluid dispenser, one that is disposable and adaptable to a variety of uses as well as having good ergonomic design and function. The dispenser should be easy to operate by using only a single hand, be attractive in appearance and aesthetics, and can be simply attached and removed from a wall, toilet, or commode.

       FIG. 2  illustrates the dispenser  30  in another embodiment as attached to a commode or toilet  31  using the mounting bracket  18  having a “U” hook  20  and a protruding ledge or extending lip  22  at the bottom of bracket  18  for aligning or sitting the back plate  2  of dispenser  30  thereon. In the embodiment shown in  FIG. 2 , tissue  28  is wetted or moistened by the liquid contents of dispenser  30  by applying downward pressure with the hand  17  to the outer end area of the hood  3 . The preferred location to mount the bracket  18  is adjacent to the toilet seat hinge assembly  29 . Mounting may be made on either side of the toilet  31 . Referring to  FIG. 9  and  FIG. 10 , the toilet bracket  18  has an upper clamp  21  and a lower sliding clamp  23 . The portions of the clamps  21  and  25  contact the toilet  31  and have an adhesive or tape suitable for the attachment to toilet  31 . The lower clamp  25  has a spring or biased lever  24  that engages a series of slits or notches  19  on the mounting bracket  18 . The contact of the upper clamp  21  and the toilet contact lower clamp  25  to the toilet  31  form a solid mount for the bracket  18  to toilet  31 . 
       FIG. 3  illustrates a cross-sectional side view of the dispenser  30 , illustrating the functional parts of the dispenser. A commercially available type compression pump  7 , common to the cosmetic and hygiene industries, is assembled and attached to the fluid container  1 . For example, pump  7  can be any type of liquid or foam dispensing pump, such as a spray pump or mist pump having any type of spray pattern or nozzle and with or without a dipstick. Acceptable means of pump  7  attachment to the fluid container  1  are by crimping, bonding and by screw thread, with the crimping being preferable. A pump head  8  of the pump  7  contains the dispensing orifice or nozzle  9  for dispensing fluid  32 . The top surface of the pump head  8  of the pump  7  has a formed semi-circular  1  dimple or recess  11 , perpendicular to the orifice or nozzle  9 , wherein recess  11  is in communication and engages with a semi-circular protrusion  6  of the hood  3 , thus forming a hinge or pivoting support. The elongated dip tube  10  of the pump  7  is bendable and can be of any length. Further, special consideration may be taken for proper filling of fluid  32  and dip tube  10  may be appropriate for low viscosity cleaning fluids. However, in another embodiment as shown in  FIG. 4 , when using high viscosity fluid  33 , a more heavy duty or large dip tube assembly  13  may be used. As shown in  FIG. 4 , a hole or opening  34  in the top of the fluid container provides an alternate means of filling the fluid dispenser or inserting the dip tube  13 . Further, opening  34  may have a removable cap or be permanently sealed. In the current embodiment, the hinge  4  for the back plate  2  and the fluid container  1  (lever) use a hole and pin hinge assembly common to the industry. However, a hinge formed utilizing bonded non-stretchable, flexible material  35  may be used as well. The back plate  2  has a nest opening  12  to receive and securely engage the “U” hook  20   a  from wall bracket  26  and to the wall or toilet bracket  18 . 
     Referring to  FIG. 3 , the back plate  2  and the hood  3  of dispenser  30  may be formed or molded as a single unitary component. However, it is contemplated within the scope of the invention that may be two separate components assembled or coupled together. Further, a hood bias or hinge  5  can be created by modifying the material being used, such as thinning the material. However, it is contemplated within the scope of the invention that any type of hinge or spring bias mechanism may be incorporated. For example, materials including but not limited to plastics, thermoplastics, polycarbonate, polypropylene, polyethylene and other and similar materials may be used for the hood  3  or hinge  5  assembly. In another embodiment, as shown in  FIG. 5 , the back plate  2  and hood  3  may be formed as separate parts and joined to form a free moving hood hinge or biasing mechanism for the hood  3  with respect to plate  2  by utilizing a bonded non-stretchable flexible material  15 . In another embodiment, as shown in  FIG. 6 , a standard hole and pin assembly hinge  16  may be used to attach the back plate  2  to the hood  3 , thereby forming a hinge for the hood  3  with respect to back plate  2 . The fluid container  1  may be formed in two parts by injection molding, compression molding or by as a single piece by blow molding. 
       FIG. 7  and  FIG. 8  illustrate the functional operation of the dispenser  30 . Here, dispenser  30  is shown utilizing three hinge points in a triangular design and further illustrate the dispenser  30  in an open ( FIG. 7 ) and closed position ( FIG. 8 ). In the open position, as shown in  FIG. 7 , the fluid container lever  1  is approximately at a 22½ degree angle  14  relative to the back plate  2 . However, it is contemplated within the scope of the invention that the lever  1  may be at any angle with respect to the back plate  2 . The angles in the triangular design show the effect of either downward pressure on the front end of the hood  3  exerted by a user or sideways or lateral pressure to the fluid container lever  1  exerted by a user in compressing the pump head  8  and dispensing the fluid within the fluid container  1  through orifice  9 . 
     It is contemplated within the scope of the invention that the fluid contained within the fluid container of the dispenser can be water or any type of liquid, cream, or gel substance having one or more cleaning agents or sanitizing ingredients.
