Title: Dispenser

Description:
BACKGROUND 
     A home care cleaning solution is typically sold in a dispenser that includes a housing and a pump assembly. A pre-mixed cleaning solution is disposed within the housing. When a user actuates the pump assembly, the cleaning solution flows (e.g., sprays) out through a nozzle in the pump assembly. 
     In some previous dispensers, the user may pour a measured amount of concentrated cleaning solution into the housing through a first end of the housing, and pour a measured amount of water into the housing through a second end of the housing. The concentrated cleaning solution and water mix together in the housing. After mixing occurs, a user may actuate the pump assembly, causing the mixture to flow out through the nozzle in the pump assembly. When all of the mixture in the housing is exhausted, the user may pour additional measured amounts of concentrated cleaning solution and/or water into the housing to create a new mixture, so that the dispenser may continue to be used with the new mixture. 
     There is sometimes a need for the user to clean with multiple cleaning solutions having varying degrees of concentration. To accomplish this currently, the user has a first dispenser having a cleaning solution with a first concentration, and a second dispenser having a cleaning solution with a second concentration. What is needed, however, is an improved dispenser for dispensing multiple cleaning solutions having varying degrees of concentration 
     BRIEF SUMMARY 
     A dispenser is disclosed. The dispenser includes a housing that defines a first opening and a second opening. The first opening provides a first path of fluid communication between a first interior volume of the housing and an exterior of the housing. The second opening provides a second path of fluid communication between a second interior volume of the housing and the exterior of the housing. A divider is positioned in the housing between the first interior volume and the second interior volume. The divider defines a third opening that provides a third path of fluid communication between the first interior volume and the second interior volume. A valve allows fluid to flow from the second interior volume, through the third opening, and into the first interior volume and prevents the fluid from flowing from the first interior volume, through the third opening, and into the second interior volume. 
     In another embodiment, the dispenser includes a housing defining a first interior volume and a second interior volume. A first opening provides a first path of fluid communication between the first interior volume and an exterior of the housing. A divider is positioned in the housing between the first interior volume and the second interior volume. The divider defines a second opening that provides a second path of fluid communication between the first interior volume and the second interior volume. A valve allows fluid to flow from the second interior volume, through the second opening, and into the first interior volume and prevents the fluid from flowing from the first interior volume, through the second opening, and into the second interior volume. A first visual indicator is positioned on a portion of the housing that is substantially transparent and defines the first interior volume. 
     A method for using a dispenser is also disclosed. The method includes introducing a first liquid into a first interior volume of a housing of the dispenser. The method also includes transferring a first portion of a second liquid from a second interior volume of the housing into the first interior volume to form a mixture. The method further includes dispensing at least a portion of the mixture from the first interior volume through a first opening in the housing to an exterior of the housing. The housing is configured to dispense a second portion of the second liquid from the second interior volume of the housing through a second opening in the housing to the exterior of the housing.

     DETAILED DESCRIPTION 
     The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. 
     As used throughout, ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range. In addition, all references cited herein are hereby incorporated by referenced in their entireties. In the event of a conflict in a definition in the present disclosure and that of a cited reference, the present disclosure controls. 
       FIG. 1  depicts a perspective view of an example of a dispenser  100 , according to an embodiment. The dispenser  100  may include a housing (e.g., a bottle)  110 . The housing  110  may include a first (e.g., upper) end  120  and a second (e.g., lower) end  150 . The housing  110  may define a first interior volume  122  and a second interior volume  152 . The housing  110  may define a first opening  124  that provides a path of fluid communication between the first interior volume  122  and an exterior of the housing  110 . As shown, the first opening  124  may be positioned proximate to the upper end  120  of the housing  110 . As described in more detail below, a first liquid may be introduced into the first interior volume  122  through the first opening  124 . The first liquid may be or include water, alcohol, surfactant, or combinations thereof and the like. 
     A first cap  126  may be coupled to the housing  110  to cover the first opening  124 . As shown, the first cap  126  may be part of a pump assembly  130  that also includes a tube  132 , an actuator  134 , and an outlet (e.g., a nozzle)  136 . In another embodiment, the first cap  126  may not be part of a pump assembly  130 . Rather, the first cap  126  may seal the first opening  124  when coupled to the housing  110  and be uncoupled from the housing  110  to allow fluid to flow through the first opening  124 . In yet another embodiment, the first cap  126  may be actuated between a first position and a second position while the first cap  126  remains coupled to the housing  110 . The first position may seal the first opening  124 , and the second position may allow fluid to flow through the first opening  124 . 
     The housing  110  may also define a second opening  154  that places the second interior volume  152  in fluid communication with the exterior of the housing  110 . The second opening  154  may be positioned proximate the lower end  150  of the housing  110 . As described in more detail below, a second liquid may be introduced into and/or dispensed from the second interior volume  152  through the second opening  154 . The second liquid may be or include a concentrated cleaning solution such as a soap, a surface cleaner detergent, a degreaser, another household cleaner, or the like. For example, the concentrated cleaning solution may be or include Fabuloso® brand household cleaner produced by the Colgate-Palmolive Company. In other embodiments, the second liquid may be or include body wash, facial cleanser, hair care or styling products, skin moisturizers, cosmetic or therapeutic skin products, or the like. In at least one embodiment, the second liquid may be in the form of a gel. 
     A second cap  156  may be coupled to the housing  110  to cover the second opening  154 . The second cap  156  may be the same type of cap as the first cap  126 , or the second cap  156  may be different. As shown, the second cap  156  is different and may be a push-pull cap that is actuated between a first position and a second position while the second cap  156  remains coupled to the housing  110 . The first position may seal the second opening  154 , and the second position may allow fluid to flow through the second opening  154  from or into the second interior volume  152 . In another example, the second cap  156  may be a flip-top cap. 
     In at least one embodiment, the first and second interior volumes  122 ,  152  may be separated by a divider  160 . The housing  110  with the divider  160  separating the first and second interior volumes  122 ,  152  may be produced via blow-molding, injection molding, rotational molding, or the like. The divider  160  may include one or more divider openings (one is shown:  162 , which is the third opening in this FIG.) that places the first and second interior volumes  122 ,  152  in fluid communication with one another. A one-way valve (e.g., a check valve)  164  may be positioned in the divider opening  162 . The one-way valve  164  may allow the second liquid to flow from the second interior volume  152  into the first interior volume  122  while preventing any liquid from flowing from the first interior volume  122  into the second interior volume  152 . 
     In another embodiment, the dispenser  100  may include a first housing (not shown) that defines the first interior volume  122  and a second housing (not shown) that defines the second interior volume  152 . The first and second housings may be coupled together, and the portions of the first and second housings that border one another may form the divider  160 . For example, the first housing may include the divider opening  162 , and the second housing may include the one-way valve  164  and/or a nozzle, or vice versa. In such embodiments, the one-way valve  164  or a nozzle on the second housing may be inserted at least partially into/through the divider opening  162  and into the first interior volume  122  when the first and second housings are coupled together. The first and second housings may be coupled together via a screw thread, a bayonet-style twist lock, a press fit, a hinged latch, an elastomeric seal, or a combination thereof. 
     In at least one embodiment, one or more vent openings (not shown) may be formed in the pump assembly  130 , the second cap  156 , the divider  160 , the check valve  164 , or a combination thereof. The vent opening may allow air to flow into first interior volume  122  and/or the second interior volume  152  when the second liquid flows from the second interior volume  152 , through the divider opening  162 , and into the first interior volume  122 . Thus, the vent opening may prevent a vacuum effect in the second interior volume  152 . 
     As described in more detail below, the first and second liquids may be combined and mixed in the first interior volume  122  to form a mixture. In at least one embodiment, the first and second liquids may be different colors. For example, the first liquid may be essentially clear or colorless, and the second liquid may be blue. In this example, the mixture may be a shade of blue that is lighter than the shade of blue of the second liquid. At least a portion of the housing  110  that defines the first interior volume  122  may be substantially clear or transparent to allow the user to see the color of the mixture. The housing  110  may include one or more visual indicators (three are shown:  172 ,  174 ,  176 ) positioned on/over the substantially clear portion of the housing  110 , which may help the user determine the concentration of the mixture in the first interior volume  122  based on the color or the volume of the mixture. For example, each visual indicator  172 ,  174 ,  176  may be a shade of a possible color of the mixture of the first and second liquids (e.g., a shade of blue) that corresponds to a known concentration of the mixture. In other words, the shade of color of each visual indicator  172 ,  174 ,  176  may correspond to a specific amount of the concentrated blue first liquid mixed and/or diluted into the essentially colorless second liquid within the first interior volume. For example, the first visual indicator  172 , which may be in the shape of a circle, may be a relatively dark shade of blue that corresponds to a first known concentration of the liquid mixture. The second visual indicator  176 , which may be in the shape of a rectangle or diamond, may be a lighter shade of blue corresponding to a second known, lesser concentration of the mixture. And the third visual indicator  176 , which may be in the shape of a triangle, may be an even lighter shade of blue corresponding to another, more diluted concentration of the mixture. 
     The housing  110  may also include a fourth visual indicator  178  positioned on/over the substantially clear portion that may help the user determine how much of the first liquid to add to the first interior volume  122 , as described in more detail below. This may aid the user in achieving the desired concentration. 
       FIG. 2  illustrates a flowchart of an example of a method  200  for filling up and using the dispenser  100 , according to an embodiment. The method  200  may be referred to together with  FIGS. 3-7 , which illustrate examples of the various steps/stages of the method  200 . The steps of the method  200  may be performed in the order described below or in any other order and some may be omitted in some implementations. 
     The method  200  may include introducing the first liquid  180  into the first interior volume  122  of the housing  110 , as at  202 . This is illustrated in  FIG. 3 . Introducing the first liquid  180  may include uncoupling and removing the first cap  126  and subsequently introducing the first liquid into the first interior volume  122  of the housing  110  through the first opening  124 . For example, the first liquid  180  may be introduced until it fills the first interior volume  122  to the fourth visual indicator  178 . The first cap  126  may then be re-coupled to the housing  110 . 
     The method  200  may also include transferring at least a portion of the second liquid  182  from the second interior volume  152  into the first interior volume  122 , as at  204 . This is illustrated in  FIG. 4 . Transferring at least a portion of the second liquid  182  may include squeezing the portion of the housing  110  around the second interior volume  152  to compress the second interior volume  152 , for example when a user grasps the portion of the housing  110  around the second interior volume  152  using their hand and applies pressure with their thumb and fingers. Each squeeze may cause a known or approximately specific amount of the second liquid (e.g., approximately 5 milliliters) to be transferred from the second interior volume  152  into the first interior volume  122 . This may help the user obtain the desired concentration of the resulting mixture in the first interior volume  122 . Instead of, or in addition to, squeezing the housing  110 , the user may invert the housing  110 , as shown, to cause or assist in transferring of the second liquid  182  from the second interior volume  152  into the first interior volume  122 . The first liquid  180  may be introduced into the first interior volume  122  of the housing  110  before or after the portion of the second liquid  182  is transferred from the second interior volume  152  into the first interior volume  122 . 
     The method  200  may also include shaking the housing  110  to mix the first and second liquids  180 ,  182  together in the first interior volume  122  to form the mixture  184 , as at  206 . This is shown in  FIG. 5 . The method  200  may also include comparing the mixture to the visual indicator(s)  172 ,  174 ,  176 , as at  208 . More particularly, the method  200  may include comparing a color of the mixture  184  to the color(s) of the visual indicator(s)  172 ,  174 ,  176 . In an example where the color of the visual indicator  176  corresponds to the desired amount or concentration of the second liquid  182  in the mixture  184 , then if the color of the mixture  184  is darker than the color of the visual indicator  176 , then step  202  may be repeated to introduce additional first liquid  180  into the first interior volume  122  of the housing  110 . If, on the other hand, the color of the mixture  184  is lighter than the color of the visual indicator  176 , then step  204  may be repeated to transfer more of the second liquid  182  from the second interior volume  152  into the first interior volume  122 . 
     The method  200  may also include dispensing at least a portion of the mixture  184  from the first interior volume  122  of the housing  110  through the first opening  124 , as at  210 . This is shown in  FIG. 6 . Dispensing at least a portion of the mixture  184  may include actuating the actuator  134  of the pump assembly  130 . As shown, the actuator  134  is a trigger that may be actuated by a user squeezing the trigger. In another embodiment (not shown), an actuator may be actuated by pushing down on a portion of the pump assembly. In response to actuating the actuator  134 , a portion of the mixture  184  may be pumped into and upward through the tube  132  and exit the pump assembly  130  via the outlet  136  (e.g., sprayed onto a surface to be cleaned). The mixture  184  may exit the pump assembly  130  as a spray or foam or the like. 
     The method  200  may also include dispensing at least a portion of the second liquid  182  from the second interior volume  152  of the housing  110  through the second opening  154  (e.g., poured or squirted onto a surface to be cleaned), as at  212 . This is shown in  FIG. 7 . Dispensing at least a portion of the second liquid  182  may include removing the second cap  156  or actuating the second cap  156  from a first position to a second position. Dispensing at least a portion of the second liquid  182  may also include squeezing the portion of the housing  110  around the second interior volume  152  to compress the second interior volume  152  while the housing  110  is right-side up, as shown in  FIG. 7 , (i.e., not inverted). Each squeeze may cause a known or approximately specific amount of the second liquid (e.g., 10 milliliters) to be dispensed from the second interior volume  152  through the second opening  154  (e.g., onto the surface to be cleaned). The portion of the second liquid  182  may be dispensed from the second interior volume  152  of the housing  110  before or after either: the first liquid  180  is introduced into the first interior volume  122  of the housing  110  (i.e., step  202 ), the portion of the second liquid  182  is transferred from the second interior volume  152  into the first interior volume  122  (i.e., step  204 ), the housing  110  is shaken to mix the first and second liquids  180 ,  182  together in the first interior volume  122  to form the mixture  184  (i.e., step  206 ), the mixture is compared to the visual indicator(s)  172 ,  174 ,  176  (i.e., step  208 ), and/or the portion of the mixture  184  is dispensed from the first interior volume  122  of the housing  110  (i.e., step  210 ). 
     Thus, the dispenser  100  may allow a user to easily and efficiently dispense the second liquid  182  as part of a diluted mixture  184  (e.g., through the first opening  124 ) or in its fully concentrated form (e.g., through the second opening  154 ) as desired or needed for different cleaning tasks. In addition, the user may be able to easily and precisely select or create the desired concentration level of the mixture  184  without significant spillage, mess, or error.
