Foam soap dispenser for push operation

Abstract

The present invention is a foam soap dispenser (10) for push operation. The dispenser (10) houses a product bottle (18 and 18′), and the dispenser (10) includes lock-out members (12a and 12b) while the product bottle (18 and 18′) includes mating lock-out members (19a, 19b, and 19′) to ensure that the correct product is used with the dispenser (10). The dispenser (10) includes a push handle (13) that pivots on a pivot point (16) to dispense product when the push handle (13) is compressed. Pushing the push handle (13) moves the handle lever assembly (25 and 25′) components, which in turn activates a product outlet (23) to dispense the product. As the handle (13) is being compressed and released, a gap (22) is created and an anti-pinch member (14) helps prevent pinching of the hand.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a foam soap dispenser for push operation.

2. Description of the Prior Art

Various types of soap dispensers are installed near sinks in restrooms. Typically, the soap dispenser houses a soap supply and generates and discharges a metered amount of soap from the soap supply with a simple actuation of a handle by a hand. Foam soaps are generally preferred over conventional liquid and gel hand soaps because they lather faster, have better coverage, and rinse more easily. Further, because less soap is typically used and there is less product waste, the soap supply must be replenished less frequently.

One type of foam soap dispenser is disclosed in U.S. Pat. No. 5,779,104 by Reidel. This pull-type dispenser generates and meters pre-foamed soap. To prevent further dispensing of drips of residual foam in an outlet channel after the desired quantity has been dispensed, the dispenser is constructed in such as way that the underpressure subsisting on the return stroke of a piston in an air chamber is effective in the foam outlet channel and sucks residual foam back into the dispenser. This no clog, anti-drip pump mechanism prevents wasteful spills and prevents unsightly leaks. Also, a reservoir allows the product bottle to be replaced before the product supply discharges completely from the dispenser, which assures a continuous supply of product without wasting product. This dispenser is a pull handle type dispenser.

Soap dispensers are often mounted to a surface in a manner in which pull operation could cause the dispenser to be pulled off the surface. Therefore, it is often desirable to utilize a push handle type dispenser to reduce the likelihood that the dispenser will be pulled off the mounting surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A dispenser handle lever assembly constructed according to the principles of the present invention is designated by the numerals 25 and 25′ in the drawings. The handle lever assembly 25 and 25′ is for use with a product dispenser designated by the numeral 10 in the drawings.

In the preferred embodiment, the dispenser 10 is of the type disclosed in U.S. Pat. No. 5,779,104 by Reidel, which is incorporated by reference herein. This patent discloses a dispenser for generating and metering foam, especially pre-foamed soap, and the dispenser includes a pull handle to dispense the soap. However, the present invention is a push handle dispenser, and the handle pivots at the front rather than at the back of the dispenser. Therefore, the dispenser of the present invention is a modification of U.S. Pat. No. 5,779,104 by Reidel to operate in a push mode rather than in a pull mode. More specifically, the dispenser has been retrofitted to accommodate the handle lever assembly components of the present invention, which is described in more detail below. The pull clip 29 is operated by the lever 30 in U.S. Pat. No. 5,779,104 while the draw bar 36 of the present invention is moved in the same direction as the clip 29 by pushing rather than pulling. The present invention may be retrofitted for use with other dispensers as well.

As shown in FIGS. 1 and 5, the dispenser 10 includes a housing 11 with a cavity 20 and lock-out members 12a and 12b, a push handle 13, and an anti-pinch member 14. In FIG. 5, a product bottle 18 containing product is placed within the cavity 20 of the housing 11 in a docking station 21, and the bottle 18 includes mating lock-out members 19a and 19b, which cooperate with the lock-out members 12a and 12b, respectively. The spout 18e of the bottle 18 is configured and arranged to mate with the docking station 21. In the preferred embodiment, the lock-out members 12a and 12b protrude from the inner surface of housing 11 while the mating lock-out members 19a and 19b are notches or indentations in the bottle 18. Therefore, the lock-out members 12a and 12b are configured and arranged to fit within the notches 19a and 19b to ensure that the correct product is being used with the dispenser 10.

In the preferred embodiment, the lock-out member 12a and the mating lock-out member 19a are located at the front of the dispenser 10, and the lock-out member 12b and the mating lock-out member 19b are located at the back of the dispenser 10 thereby being on opposing sides. More specifically, the lock-out member 12a protrudes from the front inner surface 11a of the housing 11, the lock-out member 12b protrudes from the back inner surface 11b of the housing 11, the mating lock-out member 19a is in the front 18a of the bottle 18, and the mating lock-out member 19b is in the back 18b of the bottle 18. Having the lock-out features on opposing sides helps prevent the bottle 18 from deforming around both of the lock-out members thereby excluding the use of the wrong product. The lock-out features may be located at any elevation and do not have to be located at the same elevation. It is recognized that these lock-out features may be located anywhere on the dispenser and the bottle, including on the sides 18c interconnecting the front 18a and the back 18b and on the bottom 18d of the bottle 18 opposite the spout 18e, as long as the lock-out features remain effective to exclude products that should not be used with the dispenser 10. They do not have to be on opposing sides to be effective.

The lock-out features may even be located on the same side of the dispenser and there could be more than two lock-out features. As shown in FIG. 6, the bottle 18′ includes four mating lock-out members 19′ on the front 18a′ of the bottle 18′, and the dispenser 10 would include cooperating lock-out members on the front of the dispenser 10. Again, it is recognized that these lock-out features could be located on the back 18b′, on the side 18c′, or on the bottom 18d′ opposite the spout 18e′. Further, the protrusions and the notches or indentations may be reversed on the dispenser and the bottle, and other means well known in the art may be used to act as a lock-out feature. Because the product bottle 18 or 18′ may be of a flexible material such as plastic, one lock-out member may not prevent usage of a different product because the bottle 18 or 18′ may deform around the lock-out member to fit within the housing 11. Therefore, placing more than one lock-out member within the housing 11 helps prevent usage of a different product because the bottle 18 or 18′ will be less likely to deform in two or more places and still fit within the housing 11.

An anti-pinch member 14 is placed proximate the top of the push handle 13 to help prevent pinching of the hand as the handle 13 is compressed and released to dispense the soap, as shown in FIG. 2. The anti-pinch member 14 extends from proximate the pivot points 16 on the dispenser 10 to which the handle 13 is operatively connected. More specifically, the pivot points 16 are pegs that are configured and arranged to pivotably engage apertures 17 proximate the top, back portion of the handle 13, which is shown in FIG. 1. When the handle 13 is compressed and pushed to a back position, a gap 22 is created proximate the pivot points 16 between the handle 13 and the housing 11. The anti-pinch member 14 is a curved surface to fill this gap 22. The curved surface has a lip 14a extending outwardly therefrom proximate the top of the anti-pinch member 14 to close off the gap near the top of the gap 22. Without the anti-pinch member 14, it would be possible for some skin to get pinched between the handle 13 and the housing 11 as the handle 13 is released and retracts to the forward position.

The handle lever assembly 25 or 25′ is operatively connected to the handle 13 and the dispenser 10, as shown in FIG. 1. The handle 13 includes slots 15 proximate the middle of the handle 13, and pegs 40 extending outward from an attachment point 28 or 28′ are configured and arranged to slide within the slots 15 when operatively connecting the handle 13 to the dispenser 10. The slots 15 are recessed areas on the inner surface of the handle 13 and do not extend to the outer surface. To operatively connect the handle 13 to the dispenser 10, the pegs 16 are placed within the apertures 17 and the pegs 40 are slid into the slots 15. The handle 13 is not meant to slide within the slots 15 during operation of the dispenser 10 but rather to assist in operatively connecting the handle 13 to the dispenser 10. When the handle 13 is compressed, the handle lever assembly 25 or 25′ compresses the product outlet piston 23, which is described in U.S. Pat. No. 5,779,104. The movement of the handle lever assembly 25 or 25′ is described below.

FIG. 3 shows a right side view of a handle lever assembly 25 including a push bar lever 26, a motion bar 30, a rotation lever 31, and a draw bar 36. The assembly 25 includes a corresponding left side, which is a mirror image of these components shown in the right side view. The push bar lever 26 is a relatively straight bar extending relatively upwardly and includes a pivot point 27 proximate the top of the bar. Although the terms upwardly, horizontally, and downward are being used herein to describe the relative orientations of the handle lever assembly 25 components to one another, these terms are being used figuratively and should not be construed as limiting these components to these literal orientations. For example, the push bar lever 26 is oriented in a relatively upward position and is approximately 45 degrees from being truly vertical. The pivot point 27 is operatively connected to the dispenser 10 to pivot back and forth as the push bar lever 26 is pushed and released. In FIG. 1, the push bar lever 26 is shown as handle 13 and the pivot point 27 is shown as apertures 17.

The push bar lever 26 also includes an attachment point 28 proximate the middle portion of the bar and a push member 29 extending from the attachment point 28 to the end of the bar. The push member 29 is where the push bar lever 26 is pushed by a hand, and the attachment point 28 is the point at which the push bar lever 26 is operatively connected to the motion bar 30. As discussed above, this attachment point 28 is also where the pegs 40 are located to slide within the slots 15. The motion bar 30 extends generally horizontally from the push bar lever 26 and includes an attachment point 33, to which the rotation lever 31 is operatively connected.

Since FIGS. 3 and 4 are schematic views of the handle lever assemblies 25 and 25′, the push bar levers 26 and 26′, including the push members 29 and 29′, are functionally the same as the handle 13 of FIGS. 1 and 2 even though they do not have the same outer appearance in the figures. The push bar levers 26 and 26′ and the push members 29 and 29′ are one piece that pivot together about pivot points 27 and 27′, respectively. Likewise, the pivot points 27 and 27′ are functionally the same as the apertures 17 of FIG. 1 even though they do not have the same outer appearance in the figures.

The rotation lever 31 extends generally downward from the motion bar 30 and includes a pivot point 32, an attachment point 34, and an end 35. The pivot point 32 includes pegs (not shown) extending inwardly that are configured and arranged to engage corresponding apertures (not shown) in the dispenser 10. The attachment point 34 provides a point to which the draw bar 36 is operatively connected. Proximate the attachment point 34 the rotation lever 31 slightly dog legs outward toward the back of the dispenser to assist in the pivoting of the draw bar 36. The draw bar 36 includes an end 37, which includes a bar 41 extending to the opposite side of the draw bar 36. The bar 41 is the portion of the assembly 25 that compresses the product outlet piston 23 to dispense the product.

In operation, the push bar lever 26, the motion bar 30, the rotation lever 31, and the draw bar 36 are operatively connected, as discussed above, and are pivotable at each of the respective attachment points to move the handle lever assembly 25. First, as the push member 29 is being compressed, the push bar lever 26 is pivoted to a more upright position, as illustrated by line L₁ in FIG. 3. The pivot point 27 remains in place while the attachment point 28 moves from a first position 28a to a second position 28b and the push member 29 moves from a first position 29a to a second position 29b. This movement pushes motion bar 30 backward toward the back of the dispenser thereby causing the rotation lever 31 to move, as illustrated by line L₂. The pivot point 32 remains in place while the attachment point 33 moves from a first position 33a to a second position 33b, the attachment point 34 moves from a first position 34a to a second position 34b, and the end 35 moves from a first position 35a to a second position 35b. This clockwise rotation causes the draw bar 36 to move backward toward the back of the dispenser thereby moving the end 37 from a first position 37a to a second position 37b. The linear movement of the draw bar 36 is what causes the bar 41 to compress the product outlet piston 23. This embodiment delivers approximately 11 mm of draw bar motion (approximately 0.8 ml of soap), requires approximately 28 mm of push lever motion, and requires approximately 4 pounds of force to operate.

FIG. 4 shows a right side view of a handle lever assembly 25′ including a push bar lever 26′, a motion bar 30′, a rotation lever 31′, and a draw bar 36′. A left side view of the handle lever assembly 25′ is shown in FIG. 5. The assembly 25′ includes a corresponding left side, which is a mirror image of these components shown in the right side view. The push bar lever 26′ is a relatively straight bar extending relatively upwardly and includes a pivot point 27′ proximate the top of the bar. Again, although the terms upwardly, horizontally, and downward are being used herein to describe the relative orientations of the handle lever assembly 25′ components to one another, these terms are being used figuratively only and should not be construed as limiting these components to these literal orientations. For example, the push bar lever 26′ is oriented in a relatively upward position and is approximately 45 degrees from being truly vertical. The pivot point 27′ is operatively connected to the dispenser 10 to pivot back and forth as the push bar lever 26′ is pushed and released. Again, as discussed above, the push bar lever 26′ is shown as handle 13 in FIGS. 1 and 2 and the pivot point 27′ is shown as apertures 17 in FIG. 1.

The push bar lever 26′ also includes an attachment point 28′ proximate the middle portion of the bar and a push member 29′ extending from the attachment point 28′ to the end of the bar. The push member 29′ is where the push bar lever 26′ is pushed by a hand, and the attachment point 28′ is the point at which the push bar lever 26′ is operatively connected to the motion bar 30′. As discussed above, this attachment point 28′ is also where the pegs 40 are located to slide within the slots 15. The motion bar 30′ extends generally horizontally from the push bar lever 26′ and includes an attachment point 33′, to which the rotation lever 31′ is operatively connected.

The rotation lever 31′ extends generally downward from the motion bar 30′ and includes a pivot point 32′, an attachment point 34′, and an end 35′. The pivot point 32′ includes pegs (not shown) extending inwardly that are configured and arranged to engage corresponding apertures (not shown) in the dispenser 10. The attachment point 34′ provides a point to which the draw bar 36′ is operatively connected. Proximate the attachment point 34′ the rotation lever 31′ slightly dog legs outward toward the back of the dispenser to assist in the pivoting of the draw bar 36′. The draw bar 36′ includes an end 37′, which includes a bar 41 extending to the opposite side of the draw bar 36′. The bar 41 is the portion of the assembly 25′ that compresses the product outlet piston 23 to dispense the product.

In operation, the push bar lever 26′, the motion bar 30′, the rotation lever 31′, and the draw bar 36′ are operatively connected, as discussed above, and are pivotable at each of the respective attachment points to move the handle lever assembly 25′. First, as the push member 29′ is being compressed, the push bar lever 26′ is pivoted to a more upright position, as illustrated by line L₁′ in FIG. 4. The pivot point 27′ remains in place while the attachment point 28′ moves from a first position 28a′ to a second position 28b′ and the push member 29′ moves from a first position 29a′ to a second position 29b′. This movement pushes motion bar 30′ backward toward the back of the dispenser thereby causing the rotation lever 31′ to move, as illustrated by line L₂′. The pivot point 32′ remains in place while the attachment point 33′ moves from a first position 33a′ to a second position 33b′, the attachment point 34′ moves from a first position 34a′ to a second position 34b′, and the end 35′ moves from a first position 35a′ to a second position 35b′. This clockwise rotation causes the draw bar 36′ to move backward toward the back of the dispenser thereby moving the end 37′ from a first position 37a′ to a second position 37b′. The linear movement of the draw bar 36′ is what causes the bar 41 to compress the product outlet piston 23. This embodiment delivers approximately 7 mm of draw bar motion (approximately 0.5 ml of soap), requires approximately 28 mm of push lever motion, and requires approximately 2.5 pounds of force to operate. This embodiment is particularly useful for children, handicapped people, and older people because less force is required.

With the handle lever assemblies, the motion bar and the draw bar are on the same vertical plane so the overall width of the assembly is reduced. In comparing the two embodiments shown in FIGS. 3 and 4, the handle lever assembly 25 requires more force than the handle lever assembly 25′ because the draw bar must travel a greater distance, however, more soap is dispensed due to the greater distance. The handle lever assembly 25′ requires less force because the draw bar must travel a lesser distance and, therefore, less soap dispensed.

In another embodiment, the rotation lever could have multiple holes between the two attachment points shown in FIG. 4. More specifically, an attachment point 38 and an attachment point 39 could be located between the attachment points 33′ and 34′ and the draw bar could be connected to any one of the attachment points except the attachment point to which the motion bar is connected. FIG. 5 shows an additional attachment point 38 between the attachment points 33′ and 34′. Although one and two additional attachment points are shown, it is recognized that any number of additional attachment points could be used. With several points of attachment for the draw bar, the draw bar could be located along the rotation lever to change the amount of force required to dispense a desired amount of soap. In other words, the closer the draw bar is to the motion bar, the more force would be required to dispense more soap and, conversely, the further away the draw bar is to the motion bar, the less force would be required to dispense less soap. With this changeable output feature (the adjustable positions for attachment of the draw bar on the rotation lever), the dispenser may be set for standard pressure operation, which just meets the ADA requirements, or light pressure operation, which requires less force to operate the dispenser and less soap is delivered.

In addition to dispensing foaming hand soap, there are other possible applications for the present invention. Some other possible applications include foaming bath soap or shower gel, shampoo, and foaming waterless grease hand cleanser. However, this list is not exhaustive.

The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
