DETAILED DESCRIPTION

The present disclosure is directed to absorbent microstructure arrays that can be utilized in a wide variety of products. Examples of products that can incorporate the absorbent microstructure arrays include, but are not limited to diapers, mops, hygiene, sponges, and towels—just to name a few.

The absorbent microstructure arrays can be fabricated with flexible or ridged materials. In the case of a sponge, where it is desirable to squeeze out fluids from the capillary tubes, portions of the absorbent microstructure arrays should be flexible. In the case of a diaper, portions of the absorbent microstructure arrays are ridged so the fluid is not expelled when an individual moves or sits while other portions of the absorbent microstructure arrays are flexible to allow for the diaper to conform to the body.

In some embodiments, the absorbent microstructure arrays can be utilized to uptake and store a fluid. The absorbent microstructure arrays can be used to transport the fluid in one or more embodiments.

FIG. 1 illustrates an embodiment of an example absorbent microstructure array (referred to hereinafter as “array 100”) that is comprised of a plurality of microstructure panels, such as microstructure panel 102. The plurality of microstructure panels are layered or stacked in various configurations to create the array 100. For reference, the array 100 can have a height of approximately one millimeter in one embodiment. Absorbent microstructure arrays can have any dimension desired, based on design requirements such as volume of fluid to be absorbed and a size of an object that is to incorporate the absorbent microstructure array(s).

FIGS. 2 and 3 collectively illustrate a close-up perspective view of the microstructure panel 102 that comprises a front surface 106, a back surface 108, an upper edge 110, a lower edge 112, a right edge 114, and a left edge 116. The right edge 114 and left edge 116 are best illustrated in FIG. 1. In some embodiments, the microstructure panel 102 is constructed from a base or substrate 101 that is constructed from a solid material such as a polymer, while in other embodiments the substrate 101 can be fabricated from a porous material that allows fluid to be filtered and or transmitted between the pluralities of microstructure panels.

In one embodiment, the microstructure panel 102 comprises a plurality of capillary ridges, such as capillary ridges 118 and 120, which are adjacent to one another. The capillary ridges protrude or extend from the front surface 106. In one embodiment, a spacing S between the capillary ridges 118 and 120 defines a width dimension of a capillary tube that is created when the microstructure panels are mated together to form the array 100.

The dimensions of an example capillary tube are illustrated below and described in greater detail with reference to FIG. 4.

Each of the capillary ridges extends from the upper edge 110 towards the lower edge 112. In some embodiments, the capillary ridges begin a specified distance from the upper edge 110 and terminate at a distance away from the lower edge 112 to create a border 122 around the plurality of capillary ridges. The leftmost and rightmost ones of the capillary ridges can also be set in at a distance away from the right edge 114 and left edge 116 respectively, to further define the border 122. In some embodiments the microstructure panel does not incorporate a border.

In FIG. 4, the capillary ridges, such as capillary ridge 118 comprises a height H_CR that specifies a distance that the capillary ridge 118 extends away from the front surface 106. The capillary ridge 118 also has a width dimension W_CR that specifies a distance between opposing sidewalls 124 and 126 of the capillary ridge 118. The capillary ridge 118 also comprises a contacting surface 128 that mates with the back surface of an adjacent panel.

It will be understood that the plurality of microstructure panels form the array 100 by layering the plurality of microstructure panels together such that the plurality of capillary ridges of one microstructure panel contacts the back surface of an adjacent microstructure panel to create capillary tubes that draw fluid into the absorbent microstructure array. For example, the capillary ridges 130 of microstructure panel 132 contact a back surface 134 of an adjacent microstructure panel 136.

In some embodiments, the capillary ridges contact adjacent panels to create capillary tubes, such as capillary tube 138. The capillary tube 138 has a width dimension W_CT. The width dimension of the capillary tube 138 is defined by the spacing between the capillary ridges, such as capillary ridges 140 and 142. The capillary tube 138 has a substantially rectangular cross section in this embodiment. The shape of the capillary tube 138 is defined by the shape of the sidewalls of the capillary ridges that form a portion of the capillary tube 138. For example, if the sidewalls of the capillary ridges 140 and 142 were concave in shape (measured from the contacting surface of the capillary ridge down to the front surface of the microstructure panel), the capillary tube 138 would have a substantially elliptical cross section.

In some embodiments, an enclosing microstructure panel 144 is placed over the plurality of capillary ridges of a terminal microstructure panel 146 (also referred to in FIGS. 1-3 as microstructure panel 102) of the plurality of microstructure panels. The enclosing microstructure panel has a flat front surface 148 in some embodiments.

FIG. 5 illustrates another microstructure panel 200 that comprises various capillary wall ridges, such as capillary wall ridge 202 that function to restrict fluid flow. In one embodiment, sections of capillary ridges can be separated or segmented using capillary wall ridges. For example a first section capillary ridges 204 is partially surrounded by a capillary wall ridge 202. The first section capillary ridges 204 is disposed adjacent to a second section of capillary ridges 206 that are partially surrounded by a capillary wall ridge 208. Of note, a lower area 210 of the capillary ridges is not enclosed by a capillary wall ridge. Thus, fluid can be drawn between the capillary ridges (when the microstructure panel 200 is assembled into an array) from a lower edge of the microstructure panel 200 but excluded from exiting a top edge 212 of the microstructure panel 200 and/or the right side 214 and left side 216 of the microstructure panel 200. In one use case, when the microstructure panel 200 is made from a flexible material and the microstructure panel 200 compressed, the capillary wall ridges reduce the ability of the fluid to be squeezed from the top or sides of an array.

In FIG. 6, another microstructure panel 300 comprises a capillary wall ridge 302 that extends along a length of an upper edge 304 of the microstructure panel 300 and connects to outermost capillary ridges (such as outermost capillary ridge 306) to prevent fluid from being drawn above the capillary wall ridge or outwardly from a left edge or right edge of the plurality of microstructure panels and/or array when assembled into an absorbent microstructure array.

In addition to varying the construction of the microstructure panels, some embodiments of absorbent microstructure arrays can be layered in unique manners. For example, in FIG. 7, each of a plurality of microstructure panels is laid in a feathered or offset pattern to create an absorbent microstructure array 700. In this configuration, adjacent microstructure panels such as panel 702 and 704 are set at an angle θ that is measured relative to a reference plane P. For context, the reference plane P is oriented perpendicularly to embodiments where the microstructure panels are vertically oriented such as illustrated in FIGS. 1 and 2. In one embodiment, the microstructure panels of the absorbent microstructure array 700 are set at approximately 45 degrees (other angles can likewise be utilized). The angling of the microstructure panels allows for the placement and use of the absorbent microstructure array 700 in a location where height is a limiting factor, such as thin materials like diapers or floor mop heads.

FIG. 8 illustrates an example layer of enclosing microstructure panels 800 that can be placed over exposed ones of the plurality of capillary ridges of the plurality of microstructure panels of the absorbent microstructure array 700 of FIG. 7. In some embodiments, the layer of enclosing microstructure panels 800 each has a flat front surface.

FIG. 9 illustrates an example array 900 of microstructure panels that are stacked upon one another in an offset manner. This is a collapsed configuration of microstructure panels which allows the array 900 to be laid relatively flat compared to the angled configuration illustrated in FIG. 8. This configuration of microstructure panels allows for an absorbent array that can be oriented while storing and transporting fluid a significant distance from a collection area.

FIG. 10 illustrates another example microstructure panel 1000 that comprises capillary ridges with nano-coating 1002 that function to increase the capillary action of the capillary tubes created when a plurality of the microstructure panels 1000 are joined together to create an absorbent microstructure array. In some embodiments, the nano-coating 1002 includes nano-structures such as bumps that enhance capillary action of the plurality of microstructure panels relative to the plurality of microstructure panels with no nano-structure coating. In FIG. 10, only two of the capillary channel surfaces are shown to be coated. Any number of the surfaces could be coated if desired.

FIG. 11 illustrates another example absorbent microstructure array 1100 having a plurality of microstructure panels such as microstructure panel 1102 that comprises capillary ridges that have cross-cut notches, such as cross-cut notch 1104. The cross-cut notches create additional volume for fluid collection. That is, when fluid is drawn into a capillary tube 1106, the fluid will begin to cross the capillary ridges through the cross-cut notches.

FIGS. 12 and 13 collectively illustrate another example absorbent microstructure array 1200 having microstructure panels with corrugated capillary ridges. For example, the microstructure panel 1202 comprises a corrugated capillary profile 1204 associated with a front surface 1206 of the microstructure panel 1202. In one embodiment, the corrugated capillary profile 1204 comprises alternating capillary ridges, such as capillary ridge 1208 and capillary channels such as capillary channel 1210. The capillary ridges form a first set of capillary tubes, such as capillary tube 1212, with the front surface 1206.

The plurality of microstructure panels form the absorbent microstructure array 1200 by layering the plurality of microstructure panels together such that the capillary ridges of one microstructure panel (for example panel 1214) contact the back surface of an adjacent microstructure panel (for example panel 1216) to create a second set of capillary tubes, such as capillary tube 1218, in cooperation with the capillary channels.

FIGS. 14 and 15 collectively illustrate yet another example absorbent microstructure array 1300 that comprises rows of capillary ridges of varying size and configuration. In one embodiment, the array 1300 is constructed from a plurality of microstructure panels such as microstructure panel 1302. A close up view of section A/A of the microstructure panel 1302 is illustrated in FIG. 15.

In one embodiment, the plurality of capillary ridges of the microstructure panel 1302 comprises two rows of capillary ridges. A first row 1304 of the two rows comprise capillary ridges having a first width W1 and a second row 1306 of the two rows comprise capillary ridges create spaces with a second width W2 that is different to that of the first width W1. While two rows of capillary ridges are illustrated and described, additional rows of capillary ridges can be utilized. For example, a plurality of capillary ridges rows can be arranged such that the capillary channels (e.g., space between adjacent capillary ridges) of higher rows of capillary ridges are successively narrower towards a top of the microstructure array.

In some embodiments, the first row 1304 of the two rows of capillary ridges are offset from the second row 1306 of the two rows of capillary ridges such that the first row 1304 of the two rows of capillary ridges are disposed at least partially within in the spaces (capillary channels) between the second row 1306 of the two rows of capillary ridges. The interleaving or lacing of the first and second rows creates narrower spacing between the capillary ridges of the second row 1306 and adjacent capillary rows of the first row 1304 on either side of the narrower capillary ridges of the second row 1306.

FIG. 16 illustrates a portion of another example microstructure panel 1400 that comprises a plurality of capillary ridges 1402 that are tapered from a lower edge 1404 to an upper edge 1406 to compensate for forces exerted on the fluid due to gravity. That is, as the space between adjacent capillary ridges narrows, the capillary effect increases, thereby increasing the velocity of the fluid to compensate for the force of gravity.
