## Background
FIELD OF INVENTION
The present invention is directed to methods of analyzing video or image data, and more specifically, to methods of analyzing video or image data submitted by the consumer of an absorbent article.
BACKGROUND OF THE INVENTION
Consumer goods companies may use consumer studies to learn how the absorbent articles may be improved. Improvements in technology have allowed consumer goods companies to explore new ways of collecting information regarding their products from consumers. Since many mobile devices have an integrated camera, the opportunity exists to interact with consumers through the use of the camera and the mobile phone via internet or through the carrier service.
Consequently, the need remains for a method of analyzing the data that is submitted by a consumer in the form of still or video images. In addition, the need remains for a method that allows for the analysis of data in real time. Furthermore, there remains a need for a method that allows analyzing the data to be able to improve the consumer's experience by suggesting improved placement, different amounts of wear time, and/or a different absorbent article.
SUMMARY OF THE INVENTION
A method for determining the proper placement of an absorbent article is provided. The method includes receiving a still or video image of the absorbent article in the undergarment; determining a central and a longitudinal axis for the absorbent article and any stains. The method then includes determining a center point for the absorbent article and any stains wherein the central and longitudinal axes meet. The method includes determining the distance between the absorbent article longitudinal axis and the stain longitudinal axis as well as the distance between the absorbent article central axis and the stain central axis. The method then includes adjusting the absorbent article on the undergarment according to the distances determined between the stain axis and the absorbent article axis so that the center point of the stain is less than about 20 mm from the center point of the absorbent article.

DETAILED DESCRIPTION OF THE INVENTION
The present invention is directed to the analysis of still or video images submitted by consumers of an absorbent article. As mobile devices become more powerful and common, the opportunity for the transfer of data in both directions has expanded. The present invention is directed to the analysis of data submitted by determining a longitudinal axis, a transverse, axis and a central point of the absorbent article and any stains on the absorbent article. The relationship between the stains and the article is used to give input to the consumer.
The following text sets forth a broad description of numerous different examples of the present disclosure. The description is to be construed as exemplary only and does not describe every possible combination of elements since describing every possible combination of elements would be impractical, if not impossible. It will be understood that any feature, characteristic, component, composition, ingredient, absorbent article, step or methodology described herein can be deleted, combined with or substituted for, in whole or part, any other feature, characteristic, component, composition, ingredient, absorbent article, step or methodology described herein. Numerous alternative combinations could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.
More specifically, examples disclosed herein may be configured as a system, mobile computing device, method, and/or non-transitory computer-readable medium for identifying an absorbent article from a real-time still or video image. More specifically, in some examples, the user may direct an image capturing device, such as a camera, at an absorbent article. The image capturing device may be configured to capture a real-time still or video image of the absorbent article.
The image capturing device may also be physically and/or communicatively coupled to a mobile computing device and a display device.

The computer application on the mobile computing device may contain information that is used for input to the consumer after the submission process. Alternatively, the submission may be to a remote server. Additionally, the user can indicate to the mobile computing device a keyword or other indicator related to the absorbent article during the submission process. The keyword may serve as a common identifier for the absorbent article given to all users to help interpret the submission data.
Additionally, the computer application may cause the mobile computing device to alter the real-time still or video image. As described herein, alterations of the real-time still or video image may include highlighting the absorbent article, such as creating a virtual outline around the absorbent article, creating a computer graphics interface (CGI) overlay, “graying out” background, manipulating or highlighting the background, and tagging areas of the absorbent article image with virtual objects such as, for example, an arrow, line, and/or circle. Additionally, the mobile computing device may be configured with network capabilities (e.g., to transfer absorbent article information and data to a server, etc.).
It should be understood that by graying out a background surrounding the absorbent article, the mobile computing device may utilize any visual means to de-emphasize the non-desired area. This could include converting the non-selected area to a grey-scale image, fuzzing or de-focusing the area, and putting a partial transmission mask over the area. Other mechanisms for de-emphasis are also included within the scope this disclosure.
As used herein, the term “comprising” means that the various components, ingredients, or steps, can be conjointly employed in practicing the present invention.

The input/output hardware may include and/or be configured to interface with a monitor, positioning system, keyboard, mouse, printer, image capturing device, microphone, speaker, and/or other device for receiving, sending, and/or presenting data.
Referring now to the drawings, FIG. 1 depicts a computing environment, illustrating a system for data submission, according to examples shown and discussed herein. As illustrated in FIG. 1, a network 100 may include a wide area network, such as the Internet, a local area network (LAN), a mobile communications network, a public service telephone network (PSTN) and/or other network and may be configured to electronically couple a mobile computing device 102, a user computing device 104, and a remote computing device 106.
The mobile computing device 102 may include and/or be coupled to a first image capturing device 102(a) and a second image capturing device 102(b). The first image capturing device 102(a) may be positioned on a back side of the mobile computing device 102 (as indicated by the dashed circle) and may be configured to capture real-time video images, still images, and/or other images. Similarly, the second image capturing device 102(b) may be positioned opposite the first image capturing device 102(a) and may also be configured to capture still images, real-time video images, and/or other imagery. Further, it should be understood that, while the example of FIG. 1 illustrates the image capturing devices 102(a), 102(b) as being physically part of the mobile computing device 102, some examples may be configured such that the first image capturing device 102(a) and/or the second image capturing device 102(b) reside external to the mobile computing device 102. In such a combination of elements, the image capturing devices 102(a), 102(b) may communicate image data to the mobile computing device 102 via a wired and/or wireless protocol. Similarly, while the mobile computing device 102 of FIG. 1 may be illustrated with an attached display, this is also merely an example. In some combination of elements, the display may reside external to the mobile computing device 102 and may communicate with the mobile computing device 102 via a wired or wireless protocol. In some combination of elements, the mobile computing device 102 may have both image capturing devices 102(a) and 102(b) positioned on the same side of the mobile computing device 102. The placement of both image capturing devices 102(a) and 102(b) on the same side may allow for stereoscopic image still or video capturing, commonly known as 3D images or video.
Also included in the mobile computing device 102 is an absorbent article application 144, which includes absorbent article identification and tracking logic 144(a), absorbent article selection logic 144(b), and real time image capturing and altering logic 144(c). The absorbent article identification and tracking logic 144(a) may be configured to track the location of the identified absorbent article within the image, regardless of movement of the absorbent article or the mobile computing device 102. Additionally, the absorbent article identification and tracking logic 144(a) may be used to track an outline of an absorbent article relative to an underwear or undergarment and may determine the appropriate placement of the absorbent article on the underwear or undergarment. The absorbent article tracking and identification logic 144(a) may recognize the appropriate undergarment for proper placement. Alternatively, the absorbent article tracking and identification logic 144(a) may request that the individual user input the appropriate undergarment. The absorbent article tracking and identification logic 144(a) may determine the proper placement of the absorbent article on the undergarment using inputs given by the consumer such as the type of undergarment and the manufacturer and product name of the absorbent article. The absorbent article tracking and identification logic 144(a) may also account for other inputs such as the day in the consumers' menstrual cycle, previous data related to stain location on pad, previous pad in panty placement data, total area of pad that was stained, stain pattern, soling of the undergarment, pad change frequency, and level of current or historical menstrual flow to determine the proper placement of the absorbent article. Similarly, the real-time video capturing and altering logic 144(b) may be configured to render a real-time still or video image for display, as well as alter the imagery, as described in more detail below.
Additionally, while the mobile computing device 102 is illustrated with the absorbent article selection logic 144(b), and the real-time still or video image capturing and altering logic 144(c), within the absorbent article application, this is also an example. More specifically, in some examples, a single piece of logic may perform the described functionality. Similarly, in some examples, this functionality may be distributed to a plurality of different pieces of logic, which may reside in the mobile computing device 102 and/or elsewhere. Additionally, while only one application is illustrated as being stored by the memory component, other applications may also be stored in the memory component and utilized by the mobile computing device 102.
Also illustrated in FIG. 1 is the user computing device 104. More specifically, the user computing device 104 may be configured to communicate with the mobile computing device 102 via a wireless network 100 or through a wired connection. The user computing device 104 may also be connected to an image capturing device 102(a) via the network or through a wired connection. In some examples, the mobile computing device 102 may send stored data to the user computing device 104 for backup. This data may be sent to the mobile computing device 102 to enhance accuracy of determinations made by the mobile computing device 102 and access remotely stored user profile information. Data sent to a user computing device 104 may be password protected.
Similarly, the remote computing device 106 may also be coupled to the network 100 and may be configured to communicate with the mobile computing device 102 (and/or with the user computing device 104) to receive data submissions and to upload data to the mobile computing device 102 application or to further enhance performance of the mobile computing device 102.
The network 100 interface hardware may include and/or be configured for communicating with any wired or wireless networking hardware, including an antenna, a modem, LAN port, wireless fidelity (Wi-Fi) card, WiMax card, mobile communications hardware, and/or other hardware for communicating with other networks and/or devices. From this connection, communication may be facilitated between the mobile computing device 102 and other computing devices.
It should be understood that while the mobile computing device 102, the user computing device 104, and the remote computing device 106 are depicted as PDAs, personal computers and/or servers, these are merely examples. More specifically, in some combination of elements any type of computing device (e.g. mobile computing device 102, personal computer, server, etc.) may be utilized for any of these components. Additionally, while each of these computing devices is illustrated in FIG. 1 as a single piece of hardware, this is also an example. More specifically, each of the computing devices—may represent a plurality of computers, servers, databases, etc.
The activities which might take place in establishing a connection between a mobile computing device 102 and a server may include steps like setting up a connection setting with the server. If this is the first time the user has established a connection from the mobile computing device 102, then these connection settings can be inputted (e.g., entering a unique user name and password of the individual user of the mobile computing device 102, as well as network address for the server). Alternatively, if the user has already used the mobile computing device 102, and has saved connection settings previously, these settings could be loaded and used rather than having to be separately input. A password may be requested each time regardless of prior submissions for the sake of security.
The remote computing device 106 may be a “server” computer such as a microcomputer or personal computer, or, depending on the volume of surveys to be created and/or survey data to be collected, a computer with greater storage and/or processing capacity, such as a minicomputer or mainframe. The remote computing device 106 or server may be secured using known security software to ensure confidentiality and security of the data submitted by consumers. One or more remote computing devices 106 are used by an individual to create customized surveys that are sent to the individuals using the test absorbent article. Once a survey is created, it is transferred or uploaded to the first computing device via network.
Once the connection with the server has been established, the user can use the mobile computing device 102 to determine data for submission, such as by filling out a form with appropriate metadata, and adding media to that form. Once the form has been filled out and the media captured, the application on the mobile device can validate the form data, such as by verifying that any media elements to be submitted are properly identified. The data could then be packaged into the proper format (e.g., mapped into a data structure having fields corresponding to columns in a table in the database), and added to a submission queue.
Finally, when the submission is uploaded, the submission remnants can be removed from the mobile computing device 102 and the server. Specifically, once the upload is complete and confirmed, the mobile device could send the server a delete submission request. The mobile device and the server could then remove the data, thereby leaving the database or remote computing system as storing the master copy of the submitted information, and freeing up the resources of the server and mobile devices. This may help ensure confidentiality by removing still and video image data from the mobile computing device 102.
After data has been submitted, the mobile computing device 102 may receive information from the remote computing device 106. The information may be in the form of still images or video images or words related to the proper placement of the absorbent article in the undergarment. Alternatively, the information from the remote computing device 106 may be in the form of text congratulating the consumer on the proper placement of the absorbent article.
FIG. 2 shows a mobile computer device that may be utilized in the computing environment of FIG. 1. In the illustrated example, the mobile computing device 102 includes a processor 232, input/output hardware 230, network interface hardware 234, a data storage component 236 (which stores the user data, absorbent article data, and/or other data), and a memory component 240. Additionally, the memory component 240 may be configured to store operating logic 242 and an absorbent article application 144. The processor 232 may also include and/or be coupled to a graphical processing unit (GPU).
The absorbent article application 144 may cause the mobile computing device 102 to alter the real-time still or video image to provide information related to the absorbent article. As described herein, alterations of the real-time still or video image may include highlighting the absorbent article, such as creating a virtual outline or virtual frame around the absorbent article, creating a computer graphics interface (CGI) overlay, “graying out” background, tagging the absorbent article or portions of the absorbent article image with one or more virtual objects such as, for example, an arrow, line, and/or circle. The absorbent article application 144 may also provide for different image capturing options such as, for example, zoom, black and white or grayscale effects, negative effects, sepia effects, any other effect used to impact the visual image captured by the image capturing device 102(a). The absorbent article application 144 may also virtually add information supplied to by the individual to the image or video captured by the image capturing device 102(a). Information added may include, for example, a date stamp, an identification number for the individual, an identification number for the absorbent article, or any other information that may be helpful. Additionally, the mobile computing device 102 may be configured with network capabilities (e.g., to upload still or video image data of an absorbent article, etc.).
Specifically, combination of elements disclosed herein may be configured as a system, mobile computing device 102, method, and/or non-transitory computer-readable medium for identifying an absorbent article from a real-time still or video image, as well as providing an altered version of the real-time still or video image. More specifically, the user may direct an image capturing device, such as a camera at an absorbent article. The image capturing device may be configured to capture a real-time still or video image of the absorbent article.
The mobile computing device 102 may prompt the individual to submit information. Input information collected from the consumer may be in response to questions in the form of a survey. The consumer's response to these questions may then be used to determine areas of improvement in the placement of the absorbent articles and correlations between absorbent article characteristics and the placement accounting for styles of undergarments. Consumers may be asked to submit surveys both prior and after using the product. Similarly, a survey request may occur at certain times while using the product. For example, a survey request may require submission of surveys every 3 hours for up to 12 hours. Alternatively, a survey request may request submission within a fixed time after the consumer considers the absorbent article stained. A survey request may also occur in response to the submission of video or image data by the consumer. Questions asked may be focused on, for example, description of menstrual flow, perceived flow on the heaviest flow day, length of time absorbent article was used, comfort and fit of absorbent article, perceived leakage, unintentional urine loss, location of fluid on the absorbent article or undergarment, depth of fluid on the absorbent article, stain size, or any other suitable questions. Furthermore, these questions may be asked of the consumer in any suitable fashion, for example, via the mobile computing device 102, the World Wide Web, or a paper survey. Questions may also request the consumer's age, consumer's absorbent article preference, consumer's prior absorbent article use, what other feminine hygiene products the consumer has used or is currently using, consumer's description of her flow on her heaviest day of her period, how many absorbent articles in total does the consumer use in her period, time between changing absorbent articles on the consumer's heaviest day, any leaks while using an absorbent article on the consumer's heaviest day, what is the consumer's confidence that when the absorbent article is changed during the heaviest time that the absorbent article has been fully used, what is the level of confidence the consumer has regarding the absorbent article and her interaction with the absorbent article, and the consumer's impression of future concepts and ideas. Questions may also request information related to what types of undergarments the consumer uses, how often the consumer uses a particular type of undergarments, or how a consumer places the absorbent article in the undergarment. The submission of informational and still or video image data may prompt a new survey in response to the data supplied.
The questions may be used to determine categories that may be identified as profile, segment, and/or classification. This separation into profile, segment, and/or classification may be produced in any suitable fashion, including but not limited to, questions asked of consumers, such as questions about habits, traits, personality, and/or responses to visual situations and/or images of the consumers. The profile, segment, and/or classification into which a particular consumer belongs to may be similarly performed. These questions, for example, may be based on habits, traits, personality, and/or responses to visual situations and/or images of the consumers. One system of question asking to classify consumers into profile, segment, and/or classification is psychographic segmentation.
Any suitable combination of either individual questions or groups of questions may be asked in order to collect sufficient information to provide the basis for developing correlations used to improve absorbent articles. The precise manner and wording chosen to collect this information from the consumer may vary depending on local custom, the comfort level consumers in a particular area may have in describing their menstrual flow characteristics, and the shades of meaning associated with terms which may be used in different parts of the world to collect the information desired.
In accordance with an example of the present invention, the mobile computing device 102 memory component 240 and data storage component 236 stores all the information related to the absorbent article application 144. Analysis by the absorbent article application 144 is done by the mobile computing device 102 without the need to have a connection to a remote computing device 106.
In accordance with yet another example of the present invention, a computer program product operates a remote computing device 106 to analyze the information submitted by various consumers to make correlations; for example, to determine if particular products are improperly placed more regularly. The results of these studies can be used in a variety of ways to make correlations between visual images provided by the individuals and the absorbent articles thereby improving future absorbent articles.
Data collected by a computing device is eventually transferred to a remote computing device 106, where it is stored in memory 240. Suitable encryption algorithms known in the art or other suitable methods of encryption also can be used to protect the confidentiality of personally-identifiable information, such as first name, last name, and address, or other sensitive information.
Data may be stored in one or more databases or data warehouses in memory 240. The data storage component 236 may reside local to and/or remote from the mobile computing device 102 and may be configured to store one or more pieces of data for access by the mobile computing device 102 and/or other components. Generally, a database is an organized body of information, such as a collection of data arranged for search and retrieval, and may include structured tables or records, multiple computer files, or a single file. In the illustrated example, a relational database product such as SQLServer, Oracle, or Access can be used, although any other suitable means for storing and retrieving data also may be used.
It should be understood that the components illustrated in FIG. 2 are merely exemplary and are not intended to limit the scope of this disclosure. While the components in FIG. 2 are illustrated as residing within the mobile computing device 102, this is merely an example. In some combination of elements, one or more of the components may reside external to the mobile computing device 102. In addition, while the mobile computing device 102 in FIGS. 1 and 2 is illustrated as a single device, this is also merely an example. In some combination of elements, the absorbent article identification and tracking functionality, the absorbent article selection functionality, and the real-time still or video image capturing and altering functionality may reside on different devices.
FIG. 3 depicts an interface of a real-time still or video image of how a still or video image of the absorbent article may appear on the mobile computing device 102, according to examples shown and described herein. As illustrated, in response to submitting the requested information, the mobile computing device 102 may be configured to receive, from the first image capturing device 102(a) real-time still or video image. The user may direct the first image capturing device 102(a) to an absorbent article.
An individual may choose to capture the still or video image in any method or environment they see fit. Using the method described herein allows the user to capture a still or video image in the privacy of their home or any other suitable place. The capturing of a real time image of the absorbent article allows the user to submit the requested still or video image and information relating to the absorbent article use to the absorbent article application 144 for analysis. This allows the consumer to confirm proper placement of the absorbent article in real time or to request analysis of their absorbent article and absorbent article use for analysis after use to determine cause for leakage. Suitable environments may include, for example, a public or private bathroom or any other suitable environment.
To capture a still or video image of the absorbent article, an individual can place the absorbent article in front of the image capturing device with our without the undergarment. The absorbent article may be soiled or used and be submitted for analysis or alternatively may be clean or new and submitted to determine proper placement. Alternatively, the absorbent article may be placed in the undergarment in the manner understood by the individual prior to wearing. The individual would then initiate the appropriate application or turn on the image capturing device. To place the absorbent article in front of the image capturing device, the individual may choose to remove their undergarment and absorbent article or simply pull down the undergarment containing the absorbent article without removing the undergarment and moving the image capturing device so that the absorbent article is in front of the image capturing device. If photo alignment indicia are provided, the absorbent article can be centered using the photo alignment indicia. The still or video image may be captured and prepared to be submitted to the absorbent article application 144 or uploaded to the remote computer 106 via a computing device.
Once a still or video image has been submitted by the consumer, the image may be analyzed to instruct proper placement of the absorbent article, change in usage frequency, and/or product recommendations. The image analysis logic may be programmed to determine different objects in the image, particularly the absorbent article, the undergarment on which the absorbent article is placed, any stains or bodily exudates on the absorbent article, and the legs of the consumer in case the undergarment is still located between the legs of the consumer. The image analysis logic may be programmed to determine the brand and type of absorbent article by using any recognizable indicia including print, size, shape, topsheet pattern, wing size, thickness. The image analysis logic may further determine the general form of the undergarment used by the consumer, such as, for example, boy shorts, thong, or briefs.
As shown in FIG. 4, once the image analysis logic determines the type of absorbent article 10, the logic may determine a central axis (X1) and a longitudinal axis (Y1). The two axes are used to determine a center point where the two axes meet (C1). Once the image analysis determines the type of undergarment 20, the logic may determine a central (X2) axis and a longitudinal axis (Y2). The two axes are used to determine a center point where the two axes meet (C2).
The image analysis logic may also determine if any stains 30 exist on the absorbent article. Once the image analysis logic determines that a stain exists, the logic may determine a central axis (X3) and a longitudinal axis (Y3) to determine a stain location 40. If more than one stain exists, the logic analysis may determine a central axis and a longitudinal axis for each individual stain. The logic analysis can assign the X3 and Y3 to the largest stain located on the absorbent article. Smaller stains can be assigned X and Y values greater than X3, Y3.
Once the absorbent article is recognized by the stain logic analysis, the stain logic may also determine the width (W1) and length (L1) of the absorbent article. Using the information regarding the width and length of the absorbent article, the stain logic analysis may determine the width (W2) and length (L2) of the stain to calculate an approximate surface area covered by the stain. The logic analysis may then assign the W2 and L2 to the largest stain located on the absorbent article. Smaller stains would then be assigned W and L values greater than W2, L2. The stain logic analysis software may determine an accurate area of the stain, a geometric center, and/or a geographic center based on maximum distances from the center point of the pad. Moreover, as described below, the software could also determine geometric or geographic centers of multiple stains if the relative sizes are close enough to one another.
If more than one stain exists on the absorbent article, the image analysis logic can compare the size of the stains using the area calculation. If one stain is more than three times the area of the other stain, then the image analysis may only use the central point of the larger stain. If the area of the larger stain is less than three times the area of the other stains, then the image analysis data may be set up to average the center points of each stain to create a new center point for all the stains. The new center based on the average of the centers of the three or more stains is the stain average center. Alternatively, the approximate center of multiple stains may be determined by averaging the geometric centers of individual stains, calculating a geographic center of all stains based on the overall maximum distance of any particular stain from the center point of the pad, or if the area of the largest stain is more than 1.5 times, 2 times, or 3 times the area of any other stain, simply by using the central point of the largest stain.
Once the absorbent article center, stain center, and undergarment center have been established, the image analysis logic can use the different axes to determine the distance between the absorbent article center and the stain center. This distance can be calculated in terms of both the central axes and the longitudinal axes.
The image analysis logic may then suggest moving a new absorbent article so that the center of the absorbent article is less than about 20 mm, about 10 mm, about 5 mm, about 2 mm, about 1 mm, about 0.1 mm from the center of a previous stain, or preferably, to the center point of an average of one or more previous stains evaluated by the software for the same consumer. This may be done by moving the absorbent article center by the same distance and direction as the stain offset previously determined based on the center of the stain and the center of the absorbent article.
Using stain image analysis and the size of the stain, the image analysis logic may then recommend proper placement of the absorbent article to place the center of the stain in the center of the absorbent article. This may be done by calculating the distance between the center of the stain and the center of the absorbent article and then recommending a shift in the placement of the absorbent article on the undergarment equivalent in distance and direction to the distance and direction calculated between the stain center and the absorbent article.
As shown in FIG. 5, the image analysis logic may determine the length and width of the absorbent article (L1 and W1). The image analysis logic may then also determine the length (L2) and width (W2) of any stains 30 found on the absorbent article. This data may be recorded including any time and/or global positioning data that may be included with the still or video image. Over time, the logic may determine and length and width average for the absorbent article and a length and width average for any stains (used to determine a stain area 50). If a consistent series or sequence of still or video images is received during the menstrual cycle, the logic may also determine the length of time each absorbent article is worn and an estimate flow rate based on the stain size. Using this information and other information requested of the user or determined through sensors or stored data, such as amount of time absorbent article worn, the image analysis logic may recommend proper placement of the absorbent article, use of a different absorbent article, and/or modifying the frequency of change for the absorbent article. The image analysis logic may suggest increased change frequency, for example, if the ratio of the area created by the length and width of the stain to the area created by the length and width of the absorbent article is greater than 45%, 35%, or 25%.
The image analysis logic may also recommend adjusting the changing frequency or using an different product when (L1−L2)/L1 is less than about 20%, about 30%, about 40%, about 50%. Additionally when (W1−W2)/W1 is less than about 20%, about 30%, about 40%, about 50%. Alternatively, the image analysis logic may recommend adjusting the changing frequency or using a different product when ((L1−L2)×(W1−W2)/(L1×W1)) is less than about 20%, about 30%, about 40%, about 50%. Alternatively, the image analysis software logic may determine an average area of the stain through a counting of the pixels having a darkened color relative to the total pixel count for the pad, and then calculate a stain coverage percentage.
As shown in FIG. 6, the user may receive input on adjusting the proper placement of the absorbent article 10 based on the data submitted and the image analysis logic results. The undergarment 20 on which the absorbent article 10 is placed may be divided into three sections: the front area 21, middle or crotch area 22, and the back area 23. These three sections are bisected by a longitudinal axis. The absorbent article may also have a central axis. The longitudinal axis and the central axis are used to determine a center point where the two axes meet (C1). The middle of the crotch area may contain the center point C1. The form of undergarment may be based on prior data submissions by the user. Alternatively, the user may input the form of undergarment and size of undergarment to be worn prior to receiving input regarding the proper placement of the absorbent article. The user may also input when the time of day and number of hours that the absorbent article 10 was used.
The user may be instructed to align the absorbent article in relation to both the longitudinal axis and the absorbent article center point C1. In instructing the user, the input may reference any known indicia of the absorbent article, for example: wings, graphics, absorbent cores, and/or dimensions. Each absorbent article placement input is unique to the user based on the absorbent article and the data submitted for analysis including the type and size of the undergarment, when the absorbent article can be used, and the length of the intended use. The input may incorporate prior historical data including length of period, menstrual flow profile during period, day in period that absorbent article is being used, and prior soiling or leakage incidents in relation to prior placements. The user may be instructed to move the absorbent article a length in any direction versus the traditional placement of the user such as, for example, 2 cm forward.
The input may display a graphic showing the overlay of an absorbent article with an undergarment underneath displaying the relationship between the indicia and the center of the crotch region.
The methods of the invention can be used with any suitable feminine hygiene article. Suitable absorbent articles include any type of structures, from a single absorbent layer to more complex multi layer structures. Certain absorbent articles typically include a fluid pervious topsheet, a backsheet, which may be fluid impervious and/or may be water vapour and/or gas pervious, and an absorbent element often called “core” comprised there between.
The topsheet may be manufactured from a wide range of materials such as woven and nonwoven materials; polymeric materials such as apertured formed thermoplastic films, apertured plastic films, and hydroformed thermoplastic films; porous foams; reticulated foams; reticulated thermoplastic films; and thermoplastic scrims. Suitable woven and nonwoven materials can be included of natural fibers (e.g., wood or cotton fibers), synthetic fibers (e.g., polymeric fibers such as polyester, polypropylene, or polyethylene fibers) or from a combination of natural and synthetic fibers. In one embodiment, the topsheet may be made of a hydrophobic material to isolate the wearer's skin from liquids which have passed through the topsheet. If the topsheet is made of a hydrophobic material, at least the upper surface of the topsheet is treated to be hydrophilic so that liquids will transfer through the topsheet more rapidly. This diminishes the likelihood that body exudates will flow off the topsheet rather than being drawn through the topsheet and being absorbed by the absorbent core. In one embodiment, the topsheet can be rendered hydrophilic by treating it with a surfactant. Suitable methods for treating the topsheet with a surfactant include spraying the topsheet material with the surfactant and immersing the material into the surfactant.
The topsheet can include an apertured formed film. Apertured formed films can be used for the topsheet because they are pervious to body exudates and yet non-absorbent and have a reduced tendency to allow liquids to pass back through and rewet the wearer's skin. Thus, the surface of the formed film which is in contact with the body remains dry, thereby reducing body soiling and creating a more comfortable feel for the wearer. Suitable formed films are described in U.S. Pat. No. 3,929,135, entitled “Absorptive Structures Having Tapered Capillaries”, issued to Thompson on Dec. 30, 1975; U.S. Pat. No. 4,324,246 entitled “Disposable Absorbent Article Having A Stain Resistant Topsheet”, issued to Mullane, et al. on Apr. 13, 1982; U.S. Pat. No. 4,342,314 entitled “Resilient Plastic Web Exhibiting Fiber-Like Properties”, issued to Radel, et al. on Aug. 3, 1982; U.S. Pat. No. 4,463,045 entitled “Macroscopically Expanded Three-Dimensional Plastic Web Exhibiting Non-Glossy Visible Surface and Cloth-Like Tactile Impression”, issued to Ahr, et al. on Jul. 31, 1984; and U.S. Pat. No. 5,006,394 “Multilayer Polymeric Film” issued to Baird on Apr. 9, 1991.
The absorbent core can be any absorbent member which is generally compressible, conformable, non-irritating to the wearer's skin, and capable of absorbing and retaining body fluids. The absorbent core may be manufactured in a wide variety of sizes and shapes (e.g., rectangular, hourglass, “T”-shaped, asymmetric, etc.) and from a wide variety of liquid-absorbent materials commonly used in disposable pull-on garments and other absorbent articles such as comminuted wood pulp which is generally referred to as airfelt. Examples of other suitable absorbent materials include creped cellulose wadding; meltblown polymers including coform; chemically stiffened, modified or cross-linked cellulosic fibers; tissue including tissue wraps and tissue laminates; absorbent foams; absorbent sponges; superabsorbent polymers; absorbent gelling materials; or any equivalent material or combinations of materials.
The configuration and construction of the absorbent core may vary (e.g., the absorbent core may have varying caliper zones, a hydrophilic gradient, a superabsorbent gradient, or lower average density and lower average basis weight acquisition zones; or may include one or more layers or structures). Further, the size and absorbent capacity of the absorbent core may also be varied to accommodate wearers ranging from infants through adults. However, the total absorbent capacity of the absorbent core should be compatible with the design loading and the intended use of the absorbent article.
The absorbent core may include other optional components. One such optional component is the core wrap, i.e., a material, typically but not always a nonwoven material, which either partially or totally surrounds the core. Suitable core wrap materials include, but are not limited to, cellulose, hydrophilically modified nonwoven materials, perforated films and combinations thereof.
The backsheet can comprise a liquid impervious film. The backsheet can be impervious to liquids (e.g., body fluids) and can be typically manufactured from a thin plastic film. However, typically the backsheet can permit vapours to escape from the disposable article. In an embodiment, a microporous polyethylene film can be used for the backsheet. A suitable microporous polyethylene film is manufactured by Mitsui Toatsu Chemicals, Inc., Nagoya, Japan and marketed in the trade as PG-P.
One suitable material for the backsheet can be a liquid impervious thermoplastic film having a thickness of from about 0.012 mm (0.50 mil) to about 0.051 mm (2.0 mils), for example including polyethylene or polypropylene. Typically, the backsheet can have a basis weight of from about 5 g/m2 to about 35 g/m2. However, it should be noted that other flexible liquid impervious materials may be used as the backsheet. Herein, “flexible” refers to materials which are compliant and which will readily conform to the general shape and contours of the wearer's body.
The backsheet can be typically positioned adjacent the outer-facing surface of the absorbent core and can be joined thereto by any suitable attachment device known in the art. For example, the backsheet may be secured to the absorbent core by a uniform continuous layer of adhesive, a patterned layer of adhesive, or an array of separate lines, spirals, or spots of adhesive. Illustrative, but nonlimiting adhesives, include adhesives manufactured by H. B. Fuller Company of St. Paul, Minn., U.S.A., and marketed as HL-1358J. An example of a suitable attachment device including an open pattern network of filaments of adhesive is disclosed in U.S. Pat. No. 4,573,986 entitled “Disposable Waste-Containment Garment”, which issued to Minetola et al. on Mar. 4, 1986. Another suitable attachment device including several lines of adhesive filaments swirled into a spiral pattern is illustrated by the apparatus and methods shown in U.S. Pat. No. 3,911,173 issued to Sprague, Jr. on Oct. 7, 1975; U.S. Pat. No. 4,785,996 issued to Ziecker, et al. on Nov. 22, 1978; and U.S. Pat. No. 4,842,666 issued to Werenicz on Jun. 27, 1989. Alternatively, the attachment device may include heat bonds, pressure bonds, ultrasonic bonds, dynamic mechanical bonds, or any other suitable attachment device or combinations of these attachment devices.
The backsheet may be additionally secured to the topsheet by any of the above-cited attachment devices.
The absorbent article may also include such other suitable features as are known in the art including, but not limited to, re-closable fastening system, lotion, acquisition layers, distribution layers, wetness indicators, sensors, elasticized waist bands and other similar additional elastic elements and the like, belts and the like, waist cap features, containment and aesthetic characteristics and combinations thereof.
The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm.”
Every document cited herein, including any cross referenced or related patent or application, is hereby incorporated herein by reference in its entirety unless expressly excluded or otherwise limited. The citation of any document is not an admission that it is prior art with respect to any invention disclosed or claimed herein or that it alone, or in any combination with any other reference or references, teaches, suggests or discloses any such invention. Further, to the extent that any meaning or definition of a term in this document conflicts with any meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this document shall govern.
