Abstract
A 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.

(12) 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.
(13) 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.
(14) 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.
(15) 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.
(16) 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.
(17) 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.
(18) 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.
(19) 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.
(20)
(21) 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
(22) 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
(23) 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
(24) 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
(25) 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
(26) 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.
