This disclosure concerns a dispenser for wipes. In particular, this disclosure concerns a dispenser that applies a composition onto the wipe, as the wipe is being pulled out of the dispenser and methods for use.
Microorganisms exist everywhere. People encounter microorganisms when eating or drinking, taking transportation such as airplanes, trains, and busses, visiting hotels and restaurants, studying in schools, universities, and cafeterias, completing the tasks of daily life at an office, workplace, grocery store, or retail store, in their homes, and seeking healthcare treatment at a hospital or healthcare facility. Some microorganism are harmless while others lead to infections, disease, and illness. For example, Clostridium difficile (C. diff) is a leading cause of health care associated infections. To prevent microorganisms from causing infections, disease, and illness, hard surfaces such as counters, tables, handles are wiped down to be disinfected to remove C. diff and other types of microorganisms.
Presaturated disposable wipes are a fast-growing means of applying disinfectants. The convenience of having a readily available disinfectant including applicator at point of use is extremely attractive. Despite the convenience of the presaturated wipes themselves, the current delivery “systems” (i.e., canisters, pouches) have significant drawbacks. For example, canisters are often left open, causing the wipes to dry out and thus their level of efficacy is uncertain. Wipes dispensed from plastic canisters also present challenges with respect to becoming unthreaded (wipe roll falls back into canister), or “roping” (more than one wipe is dispensed from the canister without breaking at the perforation). Dry wipes are also an appealing trend in disinfection, allowing end users, for example, to apply a diluted concentrate disinfectant directly to a roll of dry wipes, allowing the customer to “create their own wipes” on site. This approach has advantages, but also comes with potential drawbacks, for example, over or under saturation of the dry wipe with liquid disinfectant, leading to inconsistency in how many wipes are needed to wet a particular surface. Further, some dilutable chemistries have a short effective life after dilution, which may present logistical challenges to ensure that the wipes are not being used after their effectiveness is past.
There is a need for a method of providing/dispensing disinfectant wipes which are: consistently wetted, not subject to drying out between users (e.g., top left off canisters), easy to dispense one at a time without excessive fall back or roping, and in which in some cases can be used to mix chemistry which may lose efficacy within a short time after preparation to be “mixed” at the point of use. Such dispensers can find use in health care facilities, schools, grocery stores or in many other examples.
A wipe dispenser is provided that improves the prior art.
In general, this disclosure provides a hard surface wipe dispenser that has a reservoir as part of the dispenser for applying a composition onto the wipe, as the wipe is being pulled out of the dispenser. One of the advantages of such a dispenser is it provides freshly saturated, consistently wetted wipes, and that one or more liquids can be added to the wipe via the dispenser.

The system 30 includes a dispenser 32. The dispenser includes a housing 34, a removable and replaceable mixing and dispensing assembly 36, and a supply of wipes 38, depicted in
In general, the system 30 can be used to apply or dose one of the wipes 38 using a composition from the mixing and dispensing assembly 36 onto the wipe 38, as the wipe 38 is being removed from the dispenser 32.
In another example system, the system can be “wipeless”. Such a system includes mixing liquids and then dispensing the mixed liquids into either a collection tray or directly onto a wipe or towel placed under a dispenser of the mixed liquids. An example embodiment of this system is shown in
In reference now to
In accordance with principles of this disclosure, the mixing and dispensing assembly 36 includes a vessel 40. The vessel 40 includes a surrounding wall 42 defining an interior volume 43 therewithin. The vessel 40 can be used to hold and store a variety of materials that are used as part of the composition to be placed on the wipe 38. For example, the composition within the vessel 40 can be a liquid in the form of hydrogen peroxide. A variety of compositions or chemicals can be used.
The vessel 40 includes at least a first opening 44 in communication with the interior volume 43. In the preferred embodiment shown, the first opening 44 is along a top 45 of the vessel 40, when the mixing and dispensing assembly 36 is positioned in a normal and upright position, and as it is positioned within the housing 34.
The vessel 40, in the particular embodiment illustrated, also includes a tubular wall 46 (
Still in reference to
In reference now to
Mounted within the container 54 is a slide tube 58. The slide tube 58 is slidably mounted within the interior of the container 54 and will slide therewithin to change the interior volume within the container 54 and created the vacuum draw through the dip tube 56.
Located outside of the vessel 40 and surrounding an upper portion of the pump container 54 and slide tube 58 is a cap assembly 60. The cap assembly 60 can include a pump nut 61 axially against a pump bottle nut 62. Moving the slide tube 58 upwardly and away from the dip tube 56 will convey liquid from the vessel 40 through dip tube 56, into the pump container 54, and through the interior of the slide tube 58.
In reference again to
While the dispenser system 30 can have many implementations, including the bottle 68 being located anywhere convenient within the housing 34, in many embodiments, it will be convenient to have the bottle 68 connected or attached in some manner to the vessel 40. In this embodiment, the bottle 68 is held by the vessel 40. For example, in this embodiment, the holder 50 which is an integral part of the vessel 40, is sized to snugly hold the bottle 68.
The bottle 68 has a second pump 70 in communication therewith. The second pump 70 is oriented to convey the second liquid stored within the bottle 68. Attention is directed to
The second pump 70 includes a dip tube 72 extending within the interior of the bottle 68. The second pump 70 further includes a nozzle 74 positioned within a slide assembly 76. The slide assembly 76 is threadably attached to the neck 66 of the bottle 68. When the nozzle 74 receives downward force, it engages the slide assembly which creates a vacuum pressure in the dip tube 72 in order to draw the second liquid within the bottle 68 into the dip tube 72 and into nozzle 74.
The nozzle 74 includes a dispenser outlet 78 surrounded by an outer wall 80. Orthogonal to the outer wall 80 and positioned in about a middle section of the nozzle 74 is a flange extension 82. The flange extension 82 has an upper axial surface 83 oriented toward the outlet 78 and is sized to receive a pressing force in a downward axial direction (e.g., a direction toward the bottle 68) from an arm arrangement 122, described further below. As will be explained further below, shoulders 141, 142 (
Also shown in
In accordance with principles of this disclosure, the mixing and dispensing assembly 36 further includes a funnel arrangement 90. The funnel arrangement 90 is in downstream communication with the first pump 52 and second pump 70. In general, the funnel arrangement 90 receives the first liquid from the vessel 40 and second liquid from the bottle 68, mixes them, and disperses them onto the wipes 38.
In reference now to
In
The cap 102 includes a first port 106 in communication with the first pump 52. In particular, the first port is in communication and extends into the slide tube 58 of the first pump 52. The first port 106 is also in communication with the mixing chamber 92, downstream of the first port 106.
The cap 102 further includes a second port 108. The second port 108 is in communication with the second pump 70 and the mixing chamber 92.
The funnel arrangement 90 further includes a dispensing funnel 96. The dispensing funnel 96 is in communication with the upper funnel housing 94 and downstream of the mixing chamber 92. In use, the wipe 38 can be pulled through the dispensing funnel 96 from the upper funnel housing 94 and dispersed (or wetted) with a mixture of the first liquid and second liquid from the mixing chamber 92.
The dispensing funnel 96 is conical in shape and tapered from an upper rim 96a to a narrower mouth 96b, ending at an outlet end 97, in order to help wet the wipe 38 as it passes through the dispensing funnel 96. In preferred implementations, the dispensing funnel 96 is a separate piece/member from the upper funnel housing 94. The dispensing funnel 96 can be used as a “starter funnel”, in that, when loading a new wipe 38 from a roll 39, the lead wipe 38 can be threaded through the dispensing funnel 96 while it is still separate from the upper funnel housing 94. Then, the dispensing funnel 96 with the wipe 38 threaded through, is dropped through the open upper end 100 in the upper funnel housing 94, and then operably positioned within the upper funnel housing 94.
The upper rim 96a of the dispensing funnel 96 forms a lip seal 101 (
As can be seen in
In
In accordance with principles of this disclosure, the mixing and dispensing assembly 36 further includes tubing 118. The tubing 118 connects the bottle 68 to the mixing chamber 92. In this example, the tubing 118 is in intimate connection with the second port 108 in the cap 102 of the funnel arrangement 90. An opposite end of the tubing 118 is connected to the nozzle 74, such that the outlet 78 of the nozzle 74 is in communication with the tubing 118. This will allow liquid within the bottle 68 to be conveyed by the second pump 70 through the tubing 118 and into the tube mixing chamber 92, where it is mixed with the first liquid from the vessel 40.
The mixing and dispensing assembly 36, as described above, can be used as part of the dispenser 32 in order to first, apply a composition to one of the wipes 38, and then to dispense the treated wipe 38. The wipe 38 can be treated by wetting it with the first liquid and second liquid.
In reference now to
The linkage assembly 120 can be secured to the funnel arrangement 90 in a variety of fashions. In one example, the linkage assembly 120 includes an arm arrangement 122 (
The arm arrangement 122 is shown in
In reference again to
Each of the first and second arms 131, 132 has a respective free end 135, 136. Each of the free ends 135, 136 defines an open slot 138, 139 sized to removably receive and hold one of the first and second posts 114, 116 (
The base member 134 of the arm arrangement 122 defines a second pump receiver 140. The second pump receiver 140 is generally centered between the first and second arms 131, 132 along the base member 134 and is sized to removably receive a portion of the second pump 70.
The base member 134 includes first and second shoulders 141, 142 on opposite sides of the receiver 140. The first and second shoulders 141, 142 engage against a portion of the second pump 70, such that when the arm arrangement 122 moves from the idle position (
In reference again to
A first spring 148 is mounted on the spring holder 144 and is connected to the first arm 131 at a tab 150 extending from the first arm 131. A second spring 152 is part of the spring arrangement 124 and is mounted on the spring holder 144. The second spring 152 is connected to the second arm 132 at a tab 154 (
The arm arrangement 122 and spring arrangement 124 have components that are mounted within a linkage housing 156 (
When the spring arrangement 124 moves the arm arrangement 122 back to the idle position, the arm arrangement 122 acts on the first pump 52 and the second pump 70 and reprimes them, by lifting them, in which internal components in the first pump 52 and second pump 70 are lifted to put the pumps 52, 70 in a primed position and ready for dispensing.
The arm arrangement 122 is movable along a stroke length, and the stroke length can be adjusted to control for a desired volume of first liquid and second liquid to be dispensed. The longer the stroke length, the more volume of first liquid from the first pump 52 and second liquid from the second pump 70 are dispensed. Another way of adjusting for the volume of liquids to be dispensed is by adjusting a position of a stop on the upper funnel housing 94 to limit the stroke length.
In reference again to
The housing 34 includes a wipe dispenser opening 168 through the wall 160, which is sized to permit a treated wipe 38′ to be pulled therethrough.
The mixing and dispensing assembly 36 is removably and replaceably mounted within the interior volume 162. In
The back portion 165 of the housing 34 includes a top surface 170 opposite of the bottom surface 171. Within the interior volume 162 and spaced between the top surface 170 and bottom surface 171 is a shelf 172. The shelf 172 extends perpendicular to a backwall 173 and is constructed and arranged to hold a supply of the wipes 38 between the shelf 172 and the top surface 170 of housing 34. For example, when the wipes 38 are in the form of roll 39, the roll 39 can be positioned on the shelf 172 in a wipe storage volume 174. The mixing and dispensing assembly 36 can be oriented on an inner surface of the bottom surface 171 and below the shelf 172.
The system 30 may include an electronic module 185 (
A method of applying a composition onto one of the wipes 38 is now described. The composition comprising the first liquid from the vessel 40 and the second liquid from the bottle 68 mixes in the mixing chamber 92 and drains by gravity to the dispensing funnel 96, wicks onto the wipe 38, while constriction at outlet end 97 helps to wring out the wetted wipe 38′ as it is pulled from the funnel 96 to distribute the composition along the wipe 38. In many cases an upper portion, such as the upper 1 inch, of the wipe 38 remains unwetted initially, and the rest of the wipe 38 then wipes or wicks the internal flow path of the dispensing funnel 96 dry as it passes along the flow path. A portion of the wipe 38 may never come in contact with the liquid and may remain mostly dry, but efficacy is not impacted as the portion of the wipe 38 that is wet is sufficiently effective.
The treated wipe 38′ is removed from the dispensing funnel 96, such as by tearing or separating the treated wipe 38′ from the remaining supply of wipes 38.
In operation, a method of using the dispenser 32 includes grasping a portion of the wipe 38′ through the wipe dispenser 168 in the housing 34 and pulling the wipe 38′ downwardly. By pulling the wipe 38′ downwardly, this pulls down the funnel arrangement 90, which actuates the first pump 52 and the second pump 70. Actuating the first pump 52 and second pump 70 conveys a consistent amount/dose of both the first liquid from the vessel 40 and second liquid form the bottle 68, to the mixing chamber 92 to mix together in the funnel arrangement 90. The mixed first liquid and second liquid drain by gravity to the interior of the dispensing funnel 96, where it will wet the wipe 38 present in the dispensing funnel 96. When the treated wipe 38 is torn off from a remaining portion of the roll 39 of wipes 38, the funnel arrangement 90 will be returned to an idle position, in which the pumps 52, 70 are not actuated.
The step of actuating the first pump 52 and second pump 70 preferably take place simultaneously. This is done by moving the linkage assembly 120 from the idle position to an actuating position. The linkage assembly 120 ensures that a consistent dose/amount/proportion of the first liquid and second liquid are delivered to the wipe 38, every time a new wipe 38 is grasped. When the funnel arrangement 90 is pulled downwardly, this pivots the arm arrangement 122 downwardly against the spring arrangement 124, and the arm arrangement 122 actuates the first pump 52 and second pump 70.
At some point, the first liquid in the vessel 40 and second liquid in the bottle 68 will become exhausted or expired. At that point, the system 30 must be serviced. The system 30 can be serviced by opening the housing 34, removing the mixing and dispensing assembly 36 from the housing 34, and replacing the mixing and dispensing assembly 36 with a new mixing and dispensing assembly 36 having the vessel 40 filled and the bottle 68 filled. Alternatively, only the vessel 40 and/or bottle 68 can be replaced, and/or refilled and re-used. In some cases, the module 185 can be used to inform the user (directly or via the cloud) that the system 30 should be serviced, or is getting close to needing servicing, by replacement of the assembly 36, because the module 185 has sent a signal each time the pumps 52, 70 are activated.
Periodically, the supply of wipes 38 will need replacement. The housing 34 is opened, and a new supply of wipes 38, such as wipes in the roll 39 is provided and positioned within the wipe storage volume 174 on the shelf 172.
The mixing and dispensing assembly 36 is shown in
First pump 52 is within the first opening 44 and oriented to convey the first liquid stored within the interior volume 43. In this embodiment, the first pump 52 includes a spring 104 to assist in priming the first pump 52.
Bottle 68 having the second pump 70 is oriented to convey a second liquid stored within the bottle 68. In this embodiment, the vessel 40 and the bottle 68 are a single unitary member. By “single unitary member,” it is meant that they can be two separate members that are one or more of: mated, attached, secured, clipped, fastened or fitted together; or they can be molded as a single piece. In one example, the vessel 40 is molded to have a receiver (holder) for the bottle 68, and the bottle 68 is clipped/fastened/secured to the vessel 40.
