[0116] Figure 1 A perspective view of a scrubbing device (hereinafter referred to as a "scrubber," "scrubber device," "scrubbing device," "foam scrubbing device," "foam scrubber," or "device") according to an embodiment is shown. Device 100 includes a handle 102, a central body 104, and an array of scrubbing fins or dividers 106. As shown in Figure 6 and Figure 7 As can be seen in the figure, the central body 104 is flexible (e.g., deformable) in structure and includes a regular octagon, but the embodiment is not limited thereto. According to the embodiment, the octagon can be irregular. In addition, the central body can include a greater or lesser number of straight (equal or unequal) line segments connected to form a closed polygon. The central body can also include a circle. The height of the central body is 10.00 mm. Embodiments of the device may include a central body with a greater or lesser height. For example, the height of the central body can be about 3.0 mm, about 3.5 mm, about 4.0 mm, about 4.5 mm, about 5.0 mm, about 5.5 mm, about 6.0 mm, about 6.5 mm, about 7.0 mm, about 7.5 mm, about 8.0 mm, about 8.5 mm, about 9.0 mm, about 9.5 mm, about 10.0 mm, about 10.5 mm, about 11.0 mm, about 11.5 mm, about 12.0 mm, about 12.5 mm, about 13.0 mm, about 13.5 mm, about 14.0 mm, about 14.5 mm or about 15 mm.

[0117] continue Figures 1 to 7 In the example shown, the center body 104 includes a lower surface 110 and an upper surface 115. As indicated above, in one example, the distance between the upper surface and the lower surface is 10.00 mm. The handle 102 extends from the lower surface 110 of the center body 104. A three (3) point star-shaped protrusion covers the lower surface 110 of the device. The stars are aligned in a columnar manner on the lower surface. An array of scrubbing fins 106 extends from the upper surface 115 of the scrubbing device. The handle is attached to a first side 120 of the regular octagonal center body and to a second side 122 of the regular octagonal center body. The handle has a through opening 124 that receives a user's hand during use of the device.

[0118] As in Figure 4 and Figure 5 As can be seen in FIG. 1 , the handle 102 extends in a downward direction (away from the central body) while also following a curved path toward the central axis of the device, which extends through the central axis at point "A". Figure 6The handle is defined by the lines of the page of FIG. The first section 130 of the handle follows a first radius of curvature. The second section 134 of the handle follows a second radius of curvature. As the handle approaches its middle section 132 from either side, the radius of curvature increases so that the center portion of the handle follows a line with a shallow bend. As the path of the handle approaches the second side, it follows a second radius of curvature that is a mirror image of the first radius of curvature. At the attachment points of the handle to the first and second sides of the center body, the handle includes a thickness of 4.04 mm. The thickness of the handle at its middle section 132 is 3.25 mm. It should be noted that the distance between the attachment points of the handle (at the first side 120 and the second side 122) is 110 mm. Of course, the handle is not limited to these dimensions. For example, the distance between the attachment points of the handle can be about 10 mm, about 15 mm, about 20 mm, about 25 mm, about 30 mm, about 35 mm, about 40 mm, about 45 mm, about 50 mm, about 55 mm, about 60 mm, about 65 mm, about 70 mm, about 75 mm, about 80 mm, about 85 mm, about 90 mm, about 95 mm, about 100 mm, about 105 mm, about 110 mm, about 115 mm, about 120 mm, about 125 mm, about 130 mm, about 135 mm, about 140 mm, about 145 mm, about 150 mm or about 155 mm.

[0119] As in Figure 2 and Figure 3 As can be seen in FIG. 1 , the width of the handle at its midsection is 25 mm. When the handle approaches the attachment point with the first side 120 and the second side 122, the handle spans a length of 40.06 mm on each side ( Figure 7 ).

[0120] The user can control the scrubbing device by simply extending a finger through the handle with the palm facing the lower surface 110 of the central body 104. When the user applies the scrubbing device to the body, the user's hand remains in the handle with an interference fit (as further described below). Of course, the user can hold the handle in alternative ways. For example, the user can hold the handle with a fist and similarly apply the scrubbing device to the target area of ​​the body.

[0121] The scrubbing fins 106 extend upwardly from the upper surface 115 of the scrubbing device. The fins are attached at their proximal ends to an inner portion 150 of the upper surface 115 of the center body. The fins extend radially from the inner portion 150 of the upper surface 115. The inner portion 150 includes a first circle 180 and a second circle 182 (in Figure 6 180). The radius of the first circle is 10.0 mm, and the radius of the second circle is 14.99 mm. The first set of fins extends radially from the circumference of the first circle 180, and the second set of fins extends from the circumference of the second circle 182. The proximal ends of the first set of fins are equally spaced around the first circle, and the proximal ends of the second set of fins are equally spaced around the second circle.

[0122] The array of fins forms a wave pattern in which each fin follows an alternating curved path extending from the interior 150 of the center body. Figure 8 A single fin 140 is shown to illustrate its curved path. The fin 140 includes a first section 142 and a second section 144. The first section includes a first radius of curvature, and the second section includes a second radius of curvature. The first radius of curvature may be the same as the second radius of curvature. The transition from the first section to the second section may include an inflection point. According to an alternative embodiment, each fin may extend along a straight line. In addition, the fins of the device may include a varying curved path.

[0123] A plurality of radially extending fins circumferentially fill the upper surface 115 of the central body. The height of the fins alternates between 14 mm and 19 mm. Of course, alternative embodiments may include (i) fins of uniform height or (ii) fins of varying heights. If the heights vary, the fins may be arranged in a circumferentially repeating pattern or in an irregular pattern. In some embodiments, the height of the fins may be about 3.0 mm, about 3.5 mm, about 4.0 mm, about 4.5 mm, about 5.0 mm, about 5.5 mm, about 6.0 mm, about 6.5 mm, about 7.0 mm, about 7.5 mm, about 8.0 mm, about 8.5 mm, about 9.0 mm, about 9.5 mm, about 10.0 mm, about 10.5 mm, about 11.0 mm, about 11.5 mm, about 12.0 mm, about 12.5 mm, about 13.0 mm, about 13.5 mm, about 14.0 mm, about 14.5 mm, about 15.0 mm, about 15.5 mm, about 16.0 mm, about 17.5 mm, about 18.0 mm, about 18.5 mm, about 19.0 mm, about 19.5 mm, about 10.0 mm, about 10.5 mm, about 11.0 mm, about 11.5 mm, about 12.0 mm, about 12.5 mm, about 13.0 mm, about 13.5 mm, about About 14.0mm, about 14.5mm, about 15mm, about 15.5mm, about 16.0mm, about 16.5mm, about 17.0mm, about 17.5mm, about 18.0mm, about 18.5mm, about 19.0mm, about 19.5mm, about 20.0mm, about 20.5mm, about 21.0mm, about 21.5mm, about 22.0mm, about 22.5mm, about 23.0mm, about 23.5mm, about 24.0mm, about 24.5mm or about 25mm.

[0124] The upper edge of each fin has a series of ridges. The height of each ridge is 2.5mm and the width is 1.35mm. The height of the ridge is uniform and is evenly distributed along the upper edge of each fin. Of course, this height, width and gap size can vary. In addition, the fin of the alternative embodiment can have the ridges of different shapes, height, width and gap. In some embodiments, the height of the ridge is about 1mm, about 1.5mm, about 2mm, about 2.5mm, about 3mm, about 3.5mm, about 4mm, about 4.5mm or about 5mm. In some embodiments, the width of the ridge is about 0.5 mm, about 0.55 mm, about 0.6 mm, about 0.65 mm, about 0.7 mm, about 0.75 mm, about 0.8 mm, about 0.85 mm, about 0.9 mm, about 0.95 mm, about 1 mm, about 1.15 mm, about 1.25 mm, about 1.35 mm, about 1.45 mm, about 1.5 mm, about 1.55 mm, about 1.65 mm, about 1.75 mm, about 1.85 mm, about 1.95 mm, about 2 mm, about 2.15 mm, about 2.25 mm, about 2.35 mm, about 2.45 mm, about 2.5 mm, about 2.55 mm, about 2.65 mm, about 2.75 mm, about 2.85 mm, about 2.95 mm, or about 3 mm.

[0125] Figures 1 to 8 The scrubbing device is used to apply a cleaning composition to the skin of a user's body. For the purpose of this discussion, the cleaning composition can be a traditional bar soap. The user usually mixes soap and water to produce soap foam, that is, a foam made of soap and water. The scrubbing device provides a structure that effectively delivers the cleaning composition to the skin surface and provides antimicrobial properties during use and storage. In use, the fins of the device are frictionally applied to the user's skin together with water and soap. As an example, the user can apply the device to the skin area in a rotational and / or linear manner. The fins of the device capture water and soap and deliver them to the skin of the body in a sweeping motion, a circular motion, or a reciprocating motion, which frictionally applies the soap foam and the ridges of the fins to the skin surface.

[0126] As the device is moved over the skin, the fins capture the foam in a chamber. The chamber is defined by the upper surface 115 of the device, the adjacent fin walls, and the user's skin. As indicated, the fins extend radially from the interior of the central body. Figure 7(Top view of the scrubber oriented along the x-axis and y-axis) The user can move the device in a linear motion along the x-axis. As the user moves the device, the user also applies downward pressure on the device. This downward pressure causes the fins arranged transverse to the x-axis to collapse into each other in a brushing motion. During this motion, the upper edges of adjacent fins contact the skin. As the fins collapse together, the distance between the skin surface and the upper surface of the device body decreases, thereby reducing the volume of the collapsed chamber and squeezing the foam from the chamber onto the skin. As the radial axes of the fins become increasingly colinear with the y-axis, the collapse effect increases. For example, the collapse effect is greatest for fins extending along a line that forms a 90-degree angle with the x-axis. The effect decreases as the angle increases from 90 degrees to 180 degrees. Of course, the device can be directed in various mixed modes, which will change the characteristics of this collapse effect.

The alternative embodiment is similar to Figures 1 to 8 The main difference is that the fins of the alternative embodiment do not have ridges. The alternative embodiments have similar dimensions. However, the alternative embodiments may have slightly different dimensions.

[0139] Example

[0140] Examples are provided below to facilitate a more complete understanding of the present disclosure. The following examples illustrate exemplary modes of manufacturing and practicing the present disclosure. However, the scope of the present disclosure is not limited to the specific embodiments disclosed in these examples, which are only for illustrative purposes, because alternative methods can be utilized to obtain similar results.

[0142] Non-Limiting Exemplary Antimicrobial Tests

[0143] The ISO-22196 test is a method for evaluating the antimicrobial activity of plastic products. It can be used to evaluate the antimicrobial properties of many material types, which can range from coated surfaces or surfaces of monolithic compositions. Antimicrobial activity can be determined by:

[0144] R=(Ut-U0)–(At-U0)=Ut–At, where

[0145] R is antimicrobial activity;

[0146] U0 is the mean of the common logarithm of the number of viable bacteria recovered from the untreated test samples immediately after inoculation, expressed in cells / cm2;

[0147] Ut is the mean of the common logarithm of the number of viable bacteria recovered from the untreated test sample after 24 hours (hr), in units of cells / cm2;

[0148] At is the mean common logarithm of the number of viable bacteria recovered from the treated test samples after 24 hours, expressed in cells / cm2.

[0149] For common reference purposes, the % reduction is also reported in the Notes section of the sample results.

[0150] legend

[0151] CFU - Colony Forming Unit (usually quoted as surface area per unit volume). CFU is determined by plating a test sample with bacteria according to a specified method and then counting the resulting colonies.

[0152] Untreated Control (UTC) - Untreated control sample material used to demonstrate normal test performance, showing robust microbial growth.

[0153] Interval - can refer to the point or time at which the result value is determined; T0 indicates that the result is the fastest possible time from inoculation to recovery of the inoculated sample (eg, <5 min).

[0154] Result - can refer to a measure of change or abundance. Result units indicate the actual measured value, for example relative to a control value, depending on the method or test requirements.

[0155] Comments on changes to published test methods:

[0156] Several references are made to "Plate Count Agar" for test method plating after neutralization of the test sample and recovery of bacteria therefrom. As standard practice, counts are performed on appropriate plating media such as nutrient agar, tryptic soy agar, or as required for the specific organism being tested. The published standard is 35 + / - 1C incubation conditions. Standard microbiological practice for other international methods is to perform incubations at 37C + / - 1C. Unless other temperature conditions are specified, test conditions performed will be at 37C + / - 1C.

[0157] Current laboratory standards:

[0158] The test measurement uncertainty is based on established criteria provided in SOP 070601 Estimation of Measurement Uncertainty. The measurement uncertainty for this test method can be found in the FORM 071102 Bacterial Inoculum OD correlation table.

[0159] The expanded uncertainty for the k=2 test method applies to a 95% confidence level of Log10 (0.136)

[0160] The uncertainty value for CFU is obtained by converting the CFU count (C1) to a Log10 value (Log10 C1), multiplying this result by the expanded uncertainty (Log10 C1*EU), and then adding or subtracting from the Log10 value (Log C1+ / -(Log10C1*EU)); converting back by taking the antilog (1X10^(Log C1+ / -(Log10 C1*EU))), which provides the upper and lower limits of 95% confidence for CFU. Antimicrobial performance is reported as Log10 reduction and % reduction relative to untreated control samples.

[0168] test

[0169] Inoculum Preparation - After culturing the test bacteria overnight, transfer to the inoculum solution. Transfer the test bacteria to a small amount of about 1 / 500 of the prepared NB. Appropriately dilute this suspension with 1 / 500 NB to produce an estimated bacterial concentration to obtain a bacterial concentration between 1E6 CFU / ml and 4E6 CFU / ml, with a target concentration of 2.5E6 CFU / ml

[0170] Inoculation of test samples:

[0171] -The surface to be tested is the exposed external surface of the product.

[0172] - Use a pipette to pipette 0.1 ml of the prepared test inoculum onto the test surface.

[0173] - Cover the test inoculum with a 30 mm x 30 mm piece of film and press the film lightly to spread the test inoculum to the edges.

[0174] - Ensure that the test inoculum does not leak beyond the edges of the membrane.

[0175] - After the sample has been inoculated and the cover film applied, close the lid of the petri dish

[0176] Inoculation of test samples

[0177] The standard procedure for incubating inoculated samples is to incubate the plates containing the inoculated test samples (including half of the untreated test samples) at a temperature of (37 + / -) C and a relative humidity of not less than 90% for (24 + / - 1) h, unless otherwise stated.

[0178] Bacteria recovery

[0179] After the desired number of platings, viable cells were counted to determine the recovered bacterial concentration for each sample replicate.

[0186] Each test material is prepared as required by the analytical method. Each test sample is prepared in triplicate unless otherwise specified. Where available, flat samples are procured and cut into 50 x 50 mm blocks. Sample variability is adjusted as required for standard testing. Test samples will be flat and a thin film will be allowed to form on the sample surface during testing. At a minimum, samples will be managed to prevent evaporation of inoculum from the sample surface during testing, which is confirmed visually after testing. Samples are cut into 40 x 40 mm blocks.

[0187] Sampling Procedure

[0188] Unless otherwise specified, samples will be cut from the blocks provided or, if pre-cut, used as received. Unless otherwise specified, samples provided are considered homogeneous and monolithic for testing purposes, and selective cutting, single-sidedness, or other types of potential sample heterogeneity are disregarded unless sample handling instructions are provided and noted.

[0189] calculate

[0190] Antimicrobial performance = = R = (Ut-U0) – (At-U0) = Ut(24h) – At(24h), where

[0191] R is antimicrobial activity;

[0192] U0 is the mean of the common logarithm of the number of viable bacteria recovered from the untreated test samples immediately after inoculation, expressed in cells / cm2;

[0193] Ut is the mean of the common logarithm of the number of viable bacteria recovered from the untreated test samples after 24 h, in cells / cm2;

[0194] At is the mean common logarithm of the number of viable bacteria recovered from the treated test samples after 24 hours, expressed in cells / cm2.

[0197]

[0198]

[0199] Table 1 shows the results of the antimicrobial properties of the test samples of solid or hard surface treatments cultured with selected microorganisms measured using the ISO-22196 test method. The microorganisms used herein include Staphylococcus aureus and Escherichia coli. In this test method, the bacterial inoculum is contacted with the test sample for a duration of 24 hours without the inoculum drying. After such exposure, the inoculated bacteria are recovered and the concentration of the organisms is determined. The antimicrobial performance is determined by comparing the organisms recovered from the untreated material and the treated material after 24 hours of incubation. The antimicrobial performance is reported as Log10 reduction and % reduction relative to the untreated control sample. Table 1 shows that the "foam scrub" sample caused a 4.3log10 reduction (i.e., 99.99% reduction) of Staphylococcus aureus after 24 hours, while the untreated control sample increased from 3,340,000 CFU / ml Staphylococcus aureus at 0 hr to 1.03E+07 CFU / ml Staphylococcus aureus at 24 hr. Furthermore, the "foam scrub" sample resulted in a 4.7 log10 reduction in E. coli after 24 hours (ie, >99.99%), while the untreated control sample increased from 1,320,000 CFU / ml E. coli at 0 hr to 1.29E+07 CFU / ml E. coli at 24 hr.

[0210] Note: A score of "1" also applies to traces of growth due to extraneous contamination. Include non-test organisms in the final score; the notes section will indicate whether non-inoculated fungi are present.

[0211] Introduction

[0212] The ASTM G21 method provides an evaluation of the fungal resistance of the test material. The test samples are placed on nutrient salt agar and inoculated with a mixed fungal spore inoculum. The inoculum consists of spores derived from Aspergillus brasiliensis, Penicillium funiculosum, Chaetomium globosum, Trichoderma viride, and Adenostomum brevifolium fungi. The test samples are incubated for 28 days at 28C and greater than 90% relative humidity. After the incubation period, the test samples are visually evaluated for the presence and extension of fungal growth. The test result score is based on the classification provided by the test method.

[0213] The samples were evaluated and assigned scores according to the method scoring scheme. A grid scale was used to estimate the percentage coverage of the test samples based on microscopic observation using a stereo microscope.

[0214] Testing Procedure

[0215] The test sample ( Fig.16A and 16B ) and control samples ( Fig. 16C ) were placed on nutrient salt agar and sprayed with a mixed fungal spore suspension. The sample surface was thoroughly covered with droplets from the spray on the sample surface, and the culture medium part of the sample plate was inoculated. The spore concentration of each fungal culture was about 1E6 spores / ml. Unless otherwise specified, the standard test duration was 28 days. The standard test environmental conditions were 28+ / -2C and>90% relative humidity.

[0224]

[0225] Table 2

[0226] Table 2 shows the results of the ASTM G21 standard practice for determining the resistance of synthetic polymer materials to fungi. ASTM G21 is a qualitative antimicrobial test for detecting the general fungistatic activity of materials. Test results are reported on a grading scale of 0 to 4, and test notes are provided if there is an inhibition or contact inhibition zone. The fungal growth in these results is graded as follows: 0-no fungal growth, 1-trace growth (<10% coverage), 2-mild growth (10% to 30% coverage), 3-moderate growth (30% to 60% coverage), and 4-vigorous growth (~60% to complete coverage). The "foam scrub" sample and the untreated control sample were inoculated with spores from the following fungi: Aspergillus brasiliensis, Penicillium funiculum, Chaetomium globosum, Trichoderma virens, and Aureobasidium brevifolium fungi. After 28 days, the "foam scrub" sample scored 2 points, while the untreated control sample scored 4 points. It should be noted that the "foam scrub" samples had <30% coverage of fungal mycelium and spores, while the untreated control samples had >90% complete and uniform coverage of fungal mycelium and spores.
