Various embodiments generally relate to a dispenser for dispensing solutions, such as cleaning solutions. For example, various embodiments relate to dispensers that decrease financial and carbon footprint costs of cleaning products.
In general, a user may wish to have various cleaning solutions for cleaning different surfaces. For example, a user may wish to have a glass cleaning solution, a bath cleaning solution, a general-purpose kitchen cleaning solution, a metal cleaning solution, and/or the like. However, traditional cleaning arrangements require users to maintain and store separate reservoirs of cleaning solution corresponding to each desired cleaning solution. The user may not want or be able to dedicate enough safe storage space to accommodate a plurality of different reservoirs of cleaning solutions.
Moreover, traditional cleaning arrangements require that a user purchase a dispenser each time the user wishes to refill a cleaning product. This increases the financial and carbon footprint costs of cleaning products.
Example embodiments of the present invention provide concentrated cleaning pods configured to store concentrated cleaning mediums and a dispenser for dispensing the concentrated cleaning mediums therefrom. Example embodiments of the present invention allow a user to have multiple types of cleaning mediums, without requiring the user to have multiple dispensers. In various embodiments, the dispenser may be an atomizer (e.g., spray bottle), a pump dispenser (e.g., hand pump), and/or the like. In various embodiments, the concentrated cleaning mediums may be a concentrated glass cleaning solution, bath cleaning solution, general purpose kitchen cleaning solution, metal cleaning solution, hand soap, dish soap, laundry stain remover, scent neutralizing solution, air freshener, laundry detergent, cleaning powders, and/or the like. Some example embodiments of the present invention provide a user with a single use amount of cleaning solution.
According to one aspect of the present invention, a dispenser for dispensing a cleaning medium from a pod is provided. In an example embodiment, the dispenser comprises a cover housing and a base. The cover housing comprises a pod chamber, a retaining-ejecting mechanism, a puncture tool, a dispensing mechanism, a trigger mechanism, an atomization area, a drain channel, and a holding area. The base comprises a reservoir portion configured for receiving and maintaining fluid therein. The cover housing is configured to be secured to the base via an integrated attachment mechanism. When the pod is positioned within the pod chamber, the cover housing is secured to the base, and the pod is punctured and retained in the pod chamber, the concentrated cleaning medium is provided to the reservoir portion through the drain channel. When the pod is positioned within the pod chamber, the cover housing is secured to the base, the pod is punctured and retained in the pod chamber, and the trigger is activated, the diluted and/or deconcentrated cleaning solution is dispensed from the reservoir portion through the dispensing mechanism and out of the nozzle.
In an example embodiment, the dispensing pipette extends from the holding area into the base. When the cover housing is secured to the base and the dispensing pipette is inserted into the body of the base (e.g., the reservoir portion), diluted and/or deconcentrated cleaning solution can be transferred and/or dispensed (e.g., in a stream, mist, pump, and/or the like) by activation (e.g., pulling, pushing, squeezing, pressing, and/or the like) of the trigger on the cover housing from the dispensing pipette to the nozzle. In an example embodiment, the trigger mechanism may be a rearward-facing trigger mechanism, allowing a user to actuate the trigger via thumb action and/or palm action.
In an example embodiment, the base comprises a reservoir portion configured to receive a dilution chemical configured to dilute the cleaning solution. The dilution chemical is dispensed from the reservoir portion of the base through the dispensing pipette and out of the nozzle with the cleaning solution. In an example embodiment, the dilution chemical comprises water (e.g., distilled water, ionized water, filtered water, and/or tap water).
In an example embodiment, the retaining-ejecting mechanism comprises a puncture tool configured to puncture a membrane location of the pod. In an example embodiment, the pod is configured to be inserted into the pod chamber and secured in the retaining-ejecting mechanism which enables the pod to be inserted into a retained position at least partially within the recess, retained in the retained position, and released from the retained position following designated user input. In an example embodiment, pressing the pod into the pod chamber causes the cleaning solution to be infused into the drain channel and secures the pod within the retaining-ejecting mechanism. For example, the puncture tool may be a hollow puncture pin that is coupled to the drain channel such that concentrated medium may flow through the to the drain channel. The concentrated medium may then flow through the drain channel into the reservoir portion.
In an example embodiment a dispenser comprises a cover housing and a base, wherein the cover housing is configured to be couple to the base so as to enclose the reservoir, wherein the cover housing comprises a dispensing mechanism configured for selectively dispensing fluid from a reservoir of the dispenser and a chamber, wherein the chamber comprises a recess configured for receiving a pod at least partially therein and a retaining-ejecting mechanism, wherein the retaining-ejecting mechanism enables the pod to be inserted into a retained position at least partially within the recess, retained in the retained position, and released from the retained position.

A puncture tool 215 is located at the lower chamber wall 110 in an orientation configured to puncture a portion of the pod 205. The puncture tool 215 may be designed in a number of different configurations (e.g., needle, sharp, blunt, or tapered edge, etc.). In this design example, it can also be noted that the puncture tool 215 may be integrated within the design of the lower chamber wall 110 or attached separately therein.
In an example embodiment, at least one mechanical connection between the chamber 130 and the pod 205 is lined with a fluid seal 115. The seal functionally prevents fluid from passing in or out of the dispenser 50 reservoir.
In an example embodiment, a chamber wall 105 is integrated within the structure of the cover housing 100 to support the fluid seal 115 in a fixed location. This chamber wall 105 is coupled with a seal barrier 140 that contains the fluid seal 115 in the fixed location in the scenario the chamber wall 105 structure is open to the top of the chamber 130. The seal barrier 140 also provides a direct contact patch between the connection of the chamber 130 and the pod 205 to ensure an adequate seal is provided.
In an example embodiment, the seal 115 is a bellows seal, an example of which is illustrated in
In an example embodiment, a retaining-ejecting mechanism 200 comprises at least one spring 220, an insert guide 225, a clip 125, a retainer 120, and a roller stop 230.

In an example embodiment, a retaining-ejecting mechanism 200 comprises at least one spring 220, an insert guide 225, and a spring retainer 240. The retaining-ejecting mechanism 200 enables the pod 205 to be inserted into a retained position at least partially within the recess, retained in the retained position, and released from the retained position. In an example embodiment, the clip 125 is configured such at least one protrusion of the clip 125 fits into at least one cavity in the insert guide 225 and at least one cavity in the structure of the chamber 130 wall. The retainer 120 retains the position of the clip 125 and position of the insert guide 225, wherein the position of the insert guide 225 provides a known location of at least an empty position, loaded position, punctured position, retained position, and released position. The retainer 120 may be removed and/or relocated to allow movement of the clip 125 from the insert guide 225, wherein the insert guide 225 may be translated unidirectionally between one or more positions of the plurality of known locations.
In an example embodiment, a dispensing mechanism 300 comprises, a nozzle 305, an atomization area 310, a flow channel 315, a holding area 320, and a dispensing pipette 325. The dispensing mechanism 300 directs flow of the cleaning solution from the base 600 reservoir out of the nozzle 305.
In an example embodiment, a trigger mechanism comprises, a trigger handle 405, a plunger mechanism 410, a trigger spring 415, and a trigger structure 420. The trigger mechanism 400 generates a force (e.g., pressure differential, vacuum, or the like) to pull the cleaning solution into a holding area 320 upon release of the trigger handle 405 and an opposing force to dispense the cleaning solution from the holding area 320 when the trigger handle 405 in pressed. The releasing of the trigger handle 405 primes the holding area 320 with cleaning solution for the next activation of the trigger handle 405. A trigger spring 415 provides a constant tension or compression force against the plunger mechanism 410 in mechanical connection to the trigger. The trigger mechanism 400 is supported by the trigger structure 420, which may also be configured within the design of the cover housing 100.
In an example embodiment, A lower chamber wall 110 exists at the bottommost surface of the chamber 130. Beneath the lower chamber wall 110, at least one drain channel 135 exists to direct flow of the pod 205 medium into the base 600 reservoir to be mixed as a cleaning solution.
In an example embodiment, the drain channel is part of the puncture tool 215. For example, the puncture tool 215 may be at least partially hollow such that pod medium may flow through the hollow portion of the puncture tool 215 from the interior of the pod 205 into the base reservoir.
In an example embodiment, the drain channel is a pipette or other opening in the lower chamber wall 110 configured to enable pod medium exiting the pod 205 that was punctured by the puncture tool 215 to flow into the base reservoir.
In an example embodiment, a pod 205 containing a concentrated cleaning medium is inserted into the pod chamber 130 of the cover housing 100. The pod 205 is then pressed into the retained position of the retaining-ejecting mechanism 200 by the user to retain the pod 205 in the cover housing 100, and thus releasing the concentrated cleaning medium from the pod 205 into the base 600 reservoir. Next, the dispenser 50 is shaken to deconcentrate and/or dilute the concentrated cleaning medium with the contents of the base 600 reservoir. The trigger mechanism 400 can then be activated to dispense the deconcentrated and/or dilute cleaning solution from the base 600 reservoir and out of the dispensing mechanism 300. After the dosage of contents of the base 600 reservoir have been expelled for the cleaning operation, the pod 205 can be removed and properly disposed. Finally, the dispenser 50 cover housing 100 and base 600 reservoir can be rinsed before storing for the next use.

In various embodiments, the cover housing 100 further comprises a dispensing mechanism 300. The dispensing mechanism 300 may be designed in a number of different configurations (e.g., atomizer, pump dispenser, and the like). An atomization area 310 may be configured in the design of the cover housing 100 to provide a desired air to cleaning solution ratio or normal flow to a spout in an embodiment where the dispensing mechanism 300 is a pump dispenser. The nozzle 305 may be attached to the cover housing 100 via an outlet of the atomization area 310. The outlet may be designed in a number of different configurations (e.g., threaded tube, push latch, snap fit, etc.). The nozzle 305 may also be configured to provide different levels of projection or spray pattern of the cleaning solution as desired.
At the opposing end of the atomization area 310 from the nozzle 305, a flow channel 315 may provide a direction of flow of the cleaning solution from the base 600 reservoir to the dispensing mechanism 300. The cleaning solution may be extracted from the base 600 via a dispensing pipette 325 and trigger mechanism 400. The trigger mechanism 400 generates a force (e.g., pressure differential, vacuum, or the like) to pull the cleaning solution into a holding area 320 upon release of the trigger handle 405 and an opposing force to dispense the cleaning solution from the holding area 320 when the trigger handle 405 in pressed. The releasing of the trigger handle 405 primes the holding area 320 with cleaning solution for the next activation of the trigger handle 405. A trigger spring 415 provides a constant tension or compression force against the plunger mechanism 410 in mechanical connection to the trigger. The trigger mechanism 400 is supported by the trigger structure 420, which may also be configured within the design of the cover housing 100.
A clip 125 resides in one or more of the at least one insert guide stop marker 235, which implements the retaining-ejecting mechanism 200. The clip 125 may be moved outward by user input (e.g., direct contact, relocated mechanism, electromechanical button assembly, etc.) and thus away from the at least one insert guide stop marker 235 to allow movement of the insert guide 225. A retainer 120 applies constant force against the outward direction of the clip 125 to retain the insert guide 225 in at least one of the one or more known positions when motion is undesired.
The pod 205 may be configured with a puncture location 210 to release the contained concentrated powder or fluid. The puncture location 210 may be designed in a number of different configurations (e.g., metallic foil, elastomeric polymer membrane, etc.) to provide puncturing of the pod 205 after being depressed into the retaining-ejecting mechanism 200. A puncture tool 215 is located at the lower chamber wall 110 in an orientation configured to puncture a portion of the pod 205. The puncture tool 215 may be designed in a number of different configurations (e.g., needle, sharp, blunt, or tapered edge, etc.). In this design example, it can also be noted that the puncture tool 215 may be integrated within the design of the lower chamber wall 110 or attached separately therein. At least one fluid seal 115 is integrated within the chamber wall 105 to prevent spillage of the pod 205 or base 600 reservoir. The fluid seal 115 may be designed in a number of different configurations or combinations thereof (e.g., wipe seal, O-ring/gasket seal, bellows seal, etc.).

In various example embodiments, the insert guide engagement teeth 255 and spring retainer engagement teeth 260 are configured to mechanically mesh following the insertion of the pod 205 into the chamber 130. In an example embodiment, the retaining-ejecting mechanism 200 forces the insert guide 225 down onto the spring retainer 240 against the shared engagement surfaces 250. In an example embodiment, as the insert guide 225 is forced down onto the spring retainer 240, the meshed assembly (i.e., the joined insert guide 225 and spring retainer 240) is rotated a designated angle as a result of the interaction between the insert guide engagement teeth 255 and the spring retainer engagement teeth 260 to orient the cam 245 profile of the spring retainer 240 into a retained orientation. In an example embodiment, the spring 220 is held in a compressed orientation when the retaining-ejecting mechanism 200 is configured in the retained position. In an example embodiment, forcing the insert guide 225 down onto the spring retainer 240 against the shared engagement surfaces 250 again may release the spring 220 from the compressed orientation, forcing the insert guide 225 and pod 205 therein upward. For example, the rotation of the spring retainer 240 caused by the interaction of the insert guide engagement teeth 255 and the spring retainer engagement teeth 260 causes the spring retainer 240 to release the spring 220. In an example embodiment, following the cam 245 profile, the spring retainer 240 is rotated to its original orientation as the spring 220 compression is released.
In an example embodiment, the bead housing 330 comprises a valve bead 335 for diverting the cleaning solution and a pipette retainer 340 to maintain the position of the dispensing pipette 325.
In various example embodiments, the trigger mechanism 400 is configured with a trigger pivot point 425, allowing actuation of the trigger handle 405. In an example embodiment, the trigger handle 405 is tensioned about the trigger pivot point 425 via a trigger spring 415. In an example embodiment, a trigger tensioner 430 is incorporated to adjustably configure the trigger spring 415 tension as desired for the individual user and/or use case. In an example embodiment, the trigger handle 405 is located on the opposing side from the nozzle 305. For example, in an example embodiment, the trigger handle 405 and the nozzle 305 are disposed on opposite sides of the cover housing 450 from one another. This configuration provides a rearward-facing trigger mechanism 400. In an example embodiment, the rearward-facing trigger mechanism 400 is intended for actuation via a user's thumb or palm. In various example embodiments, the actuation of the trigger mechanism 400 forces a plunger mechanism 410 to provide fluid pressure on the stored cleaning solution, thus transporting the fluid out of the holding area 320, into the atomization area 310, and out of the nozzle 305. In an example embodiment, when the trigger mechanism 400 is released, a vacuum transports fluid back into the holding area 320 for future use.
Example embodiments of the present invention provide cleaning pods for storing and providing concentrated cleaning mediums and a dispenser 50 for diluting and/or deconcentrating the concentrated cleaning mediums (e.g., to form a diluted and/or deconcentrated cleaning solution) and dispensing the diluted and/or deconcentrated cleaning solution.
Example embodiments of the present invention provide an attachment mechanism 500 to attach the cover housing 100 to the base 600. The attachment mechanism 500 may be designed to accommodate threads (e.g., twisted and/or screwed) onto and/or into the design of the cover housing 100 and/or base. In an example embodiment, the attachment mechanism 500 is configured as part of the design of the cover housing 100. In an example embodiment, the attachment mechanism 500 is configured as part of the design of the base 600. In an example embodiment, the attachment mechanism 500 is configured independently from either the design of the cover housing 100 and/or the design of the base 600 to operate as a singular mechanism configured to attach the cover housing 100 to the base 600 without regard to the design of the cover housing 100 and/or the design of the base 600.
Example embodiments of the present invention also provide an insert guide 225 for the cleaning pod 205. The insert guide 225 provides a guided unidirectional translation of the pod 205 when inserted into or removed from the chamber 130. A plurality of positions is known and the insert guide 225 is designed to accommodate the aforementioned positions. At least one insert guide stop marker 235 may be integrated in the design of the insert guide 225 to achieve the positioning of the known positions. A clip 125 may be placed in one or more of the at least one insert guide stop markers 235 to hold a desired position of the insert guide 225. A retainer 120 may also be incorporated to retain the clip 125 within the bounds of the at least one insert guide stop marker 235 to prevent undesired and/or unintentional movement of the insert guide 235. In this example embodiment, the insert guide 225 provides the means of the retaining-ejecting mechanism 200. In an example embodiment, the fluid seal 115 also enables the cleaning pod 205 to maintain position within the retaining-ejecting mechanism 200 due to the friction fit within the bounds of the fluid seal 115.
In an example embodiment, the pod 205 is configured to contain 0.5 to 2 ounces of the concentrated cleaning medium. In an example embodiment, the pod 205 is configured to contain 0.25 to 1.25 ounces of concentrated cleaning medium (e.g., 0.5 to 1 ounce). In an example embodiment, the pod 205 is configured to contain 1.5 to 3 ounces of the concentrated cleaning medium. In an example embodiment, the pod 205 is configured to contain 1-2 ounces of the concentrated cleaning medium. In an example embodiment, the reservoir portion has a convex end surface configured to direct the diluted and/or deconcentrated cleaning solution toward a mouth of the dispensing pipette. In an example embodiment, the mouth of the dispensing pipette extends from the center of the cover housing 100 into the center of the base. In an example embodiment, the base comprises a metal or other resilient material such as glass, wood, plastic, rubber, and/or the like. In an example embodiment, the reservoir portion has a capacity of 10-30 ounces. In an example embodiment, the reservoir portion has a capacity of 5 to 15 ounces. In an example embodiment, the reservoir portion has a capacity of 20 to 40 ounces.
According to another aspect of the present invention, a pod 205 is provided. In an example embodiment, a pod 205 comprises a cup portion and a puncture membrane portion. The puncture membrane portion is configured to seal concentrated cleaning medium within the cup portion.

In an example embodiment, the pod 205 is configured to contain 1.5 to 3 ounces of the concentrated cleaning medium. In an example embodiment, at least a portion of the pod 205 comprises metal. In various embodiments, the pod 205 may be comprised of a natural post recycled material, rubber, aluminum, plastic, cardboard, paper, etc. The shape of the pod 205 may be round/spherical, cubic, ovoid, polyhedron (e.g., a tetrahedron, pyramid, cuboid, rectangular cuboid, etc.), and/or the like, as appropriate for the application.
According to yet another aspect of the present invention, a method of dispensing a cleaning solution from a pod 205 is provided. In an example embodiment, the method comprises providing a dispenser 50. The dispenser 50 comprises a cover housing 100 comprising a pod 205 chamber 130 configured to receive a pod 205 containing concentrated cleaning medium therein, a base, and a dispensing mechanism 300 extending from the nozzle into a reservoir portion of the base. The cover housing 100 comprises a retaining-ejecting mechanism 200 which enables the pod 205 to be inserted into a retained position at least partially within the recess, retained in the retained position, and released from the retained position following designated user input, drain channel 135, a dispensing mechanism 300, a trigger mechanism 400, an attachment mechanism 500, and the pod 205 chamber 130. The base 600 comprises a reservoir portion configured for receiving the concentrated cleaning medium from the pod 205, for example, via the drain channel 135. The method further comprises diluting the concentrated cleaning medium with a dilution chemical in the reservoir portion to form a diluted and/or deconcentrated cleaning solution and activating the trigger handle 405. Activating the trigger handle 405 causes diluted and/or deconcentrated cleaning solution (e.g., a mixture of concentrated cleaning solution and dilution chemical) to be dispensed from the reservoir portion, through the dispensing pipette 325, and out of the nozzle 305.
