IMPROVED REMOVABLE TABS FOR ADHERENT INSERTS OF A TAPETE
BACKGROUND OF THE INVENTION The present invention relates to a mat.
More specifically, the invention provides a mat that includes a cleanable portion. The mat may also include a component for water dissipation, a water-absorbing component, a coupling component, graphics for each purpose, a transparent cleanable portion, an adherent surface on the cleanable portion, an antibacterial composition, an antifungal composition, and a fragrance The cleanable portion can be erodible and can include a plurality of reusable and cleanable layers. If an adherent surface is included in the mat, the anti-slip feature may be associated with the adherent surface to help prevent slippage on a possibly wet adherent surface. Additionally, a detector system may be included on the mat to assist the user in identifying when the mat may need cleaning. It is known the mats to clean the soles of the shoes of people who go to the entrance to an area or a particular room. A problem with the mats in general is the way in which the mat is maintained. Ref. 156335 sufficiently clean so that it can exercise its function of cleaning the shoes of the person when, by its nature, it is purposely dirty when performing its function. The known mats can be made of a single piece of unitary material. Although these single-textured mats can be kept clean, for example when washing the mat, it may be required that the entire mat be removed from its place for washing and therefore the mat is not available when desired while the entire mat is cleaned. Alternatively, even if the mat can be cleaned in place, which may not be a possibility if it is located, for example in an area with carpet, it may not be convenient to clean the mat in place. The patent of E.U.A. No. 3,785,102 to Amos discloses a throw-away mat comprising a plurality of disposable stacked sheets where, when a particular sheet becomes soiled, the soiled sheet is peeled off and discarded. The next sheet that remains exposed after the dirty sheet has been discarded is clean and therefore a clean surface is available again. However, there may be problems associated with disposable foil mats. Discarding each dirty sheet may not be economical since each sheet is discarded after it becomes dirty. Additionally, after a certain finite number of discarded sheets, sheets will not remain and therefore an effective cleaning surface is not available. The patent of E.U.A. No. 3,785,102 to Amos also discloses that an adhesive can be provided on each upper surface of the sheet to improve its ability to remove dirt from a person's shoes. However, again, these sheets are not cleanable and therefore are not reusable. The patent of E.U.A. No. 3,717,897 for Amos et al., describes a pad for cleaning shoes and wheels. The pad includes a thin, water-washable adhesive that covers the top surface to remove dirt from shoes and wheels. Although the '897 patent discloses a pad with a water-washed adhesive top surface, the pad is not known for use in domestic or office-type applications. As stated in the '897 patent, the pad is placed at the entrance allowing passage to a clean room. Adherent mats are by far the most popular for use in indoor environments and are removed from outdoor entrances, for example for clean rooms within the buildings in which they are used., for example hospital rooms, computer chip manufacturing spaces and gyms. In this way, no adherent mats are known for use in areas that are adjacent to the entrances that allow passage from the outside environment, for cleaning the soles of a person's shoes before entering a building, for example in an entrance in a hall or on an outside porch. Adherent mats are not known for use in domestic or office-type applications, for example for use at home or in a business office, because various deficiencies are known. One of these deficiencies is that its adherent surface will not be as effective if it gets wet. Therefore, if a mat with an adherent surface is used in an outdoor environment, such as on the outdoor porch mentioned above, or in an indoor environment that is adjacent to or near an exterior entrance, such as an entrance in a hallway of a In the case of a house or a business, for the cleaning of the person's shoes before they go further into a house or business, the mat is likely to get wet and therefore not be effective. The mat can get wet, for example, by the humidity of the atmosphere or from the humidity transported by the soles of the shoes of the people who step on the mat. Additionally, if the adherent surface gets wet, it can become slippery and therefore can be a danger to the person who steps on it.
Additional deficiencies when using known adherent mats for home or office type applications, as discussed above, is their likelihood of being slip hazards and their lack of aesthetic appearance. In the '897 patent, because the pad is designed for use in clean room environments, it adheres adhesively to the floor of the passage in the front of the entrance door. This may be satisfactory to keep the mat in place in clean room type applications, however, if you try to use the pad '897 on a carpet floor, the pad does not adhere properly to the carpet and therefore can the danger of slippage is present. This can result in significant feasibility problems. The pad '897 does not have enough mass to stay in place without using an adhesive. Regarding aesthetics, because adherent mats are known only for their additional characteristics, and therefore for use only in applications of "clean room" type are not aesthetically pleasing. Therefore, for at least the above reasons, adhesive tapestes are not known for use in home or office type applications. There are additional drawbacks with known mats that are related to adequacy problems for a particular buyer and lack of additional cleaning properties. A rug can be the first object that a visitor finds in a particular house or business. In this way, the owner of the house or business may want to use the mat to graphically present an initial greeting or a message to the visitor. Although mats that can include a greeting are known, currently there is no known something that allows a particular buyer to adapt the displayed graphic so that the message is adapted to convey a particular message desired by the buyer. For example, in the Halloween season, the buyer may want a rug that shows a "Happy Halloween" message. In another situation, the buyer may wish to greet a particular visitor with a message such as "Hi, Joe". Currently, it is not known to provide a rug where a person can adapt the mat to show a particular message that you want to present and, in certain circumstances, even change the message of the mat you want to present. An additional problem with the known rugs mentioned above is that they are limited in their ability to clean the soles of a person's shoes. Although the known mats may be able to remove dirt particles from the soles of the shoes, they are not able to disinfect the soles not to provide a scent to the soles in order to help mask any unpleasant odors that may be related to the shoes. . A further drawback with known mats, even if they are cleanable, is that they do not help the user determine at what point the mat may require cleaning. Generally, the owner or the carpet guard does not continuously or regularly monitor the condition of the mat regarding its cleaning. Therefore, the mat may require cleaning, and because the owner is not consciously monitoring the mat's condition, there may be a significant period of time before the owner realizes that the mat requires cleaning. Therefore, it would be desirable to help the owner / caretaker of the mat to determine when the mat requires cleaning. Therefore, it would be desirable to provide an improved mat that can correct the deficiencies that exist with currently known rugs. The improved mat of the present invention corrects the deficiencies of the prior art and may include a base portion that incorporates a cleanable portion that is adapted to be removed removably within the mat. The mat can also include features such as water dissipation capacity, a water absorption capacity, a cushioning capacity, graphics for each purpose, a transparent portion, an adherent surface on the cleanable portion, an antibacterial composition, an antifungal composition and a fragrance. The cleanable portion can include the characteristics of being erodible and contain a plurality of cleanable reusable layers. If an adherent surface is included in the mat, the anti-slip feature can be associated with the adherent surface to help prevent slippage on a possibly wet adhesive surface. Additionally, a detector system may be included in the mat to assist the user in identifying when the mat may require cleaning. Other features will be apparent from the detailed description that follows.

DETAILED DESCRIPTION OF THE I VENTION Figure 1 illustrates a first embodiment of a mat 100 in accordance with the principles of the present invention. As can be seen in Figure 1, the mat 100 includes a base portion 200 and a cleanable insert portion 300. As will be further described later in this specification, in this embodiment, the cleanable portion 300 is received within the base portion 200 and can be detached from the base portion 200. Figure 2 illustrates an exploded perspective view of the mat of Figure 1. As can be seen in Figure 2, the base portion 200 is made as a flat, generally flat member and defines a recess 210 within the upper surface of the base portion 200. The base portion 200 provides sufficient weight and mass to hold the cleanable insert portion 300 and maintain the placement of the mat on the surface on which it is placed. The base portion 200 may include, as will be discussed later, a water dissipation capacity, a water absorption capacity and a lodging capacity and may be constituted of materials such as polyurethane, polyisoprene and other cross-linked elastomeric materials, such as nylon-β, molded or woven to form a porous structure. The recess 210 can be configured in any of a variety of geometric configurations, however, in the present embodiment, the recess 210 is configured in a rectangular shape. The recesses 210 have a length Li and a width Wx. The depth of the recess 210 is such that it is capable of receiving therein a cleanable insert portion 300 so that when the cleanable insert portion 300 is received within the recess 210, the upper surface of the cleanable insert portion 300 is generally in the same plane as the upper surface of the base portion 200. The upper surface of the base portion 200 may be colored with some color depending on the wishes of the particular purchaser, however, it is preferable that a color be used that minimizes the visibility of any dirt that accumulates by the base portion 200. . For example, it may be desirable to use darker colors for the upper surface of base portion 200 instead of lighter colors. However, again, any particular color can be used for the base portion 200, and particularly the upper surface of the base portion 200, depending on the particular wishes of an individual. Additionally, the base portion 200 may be translucent or opaque. As can be seen in Figure 2, the surface of the base portion 200 which defines the lower part of the recess 210 may include graphics 220 on said surface. In the modality that is illustrated, the graphic includes pictographic representations of flowers and a text message that presents the word "WELCOME" (WELCOME). The present invention is not limited to any particular graphic within the recess 210 and the present invention may include any of a variety of different shapes or graphics. The graphics 220 can be modified and in this way can be adapted by a person after the mat has been acquired by the owner. The owner can adapt the rug for your home or office and in this way you can modify the graphic that can be considered appropriate for. a particular situation on the part of the individual to be shown in another situation. For example, the graphic may show a message that says "Happy Halloween" in the Halloween season and can be modified to display a sign that says "Happy Holidays" during the winter holiday period. In this way, as can be understood, the graphics are modifiable by the user and therefore can be adapted to the particular wishes of a particular user. As stated in the above, the present invention is not limited to any particular form for the graphic 220. The graphic 220 may be adapted by a user to include any of a variety of colors, images, messages or other representations different than the user may wish to present. In addition, the visible intensity of one or more of the colors can be modified. For example, a color that glows in the dark may be included in graphic 220 for occasions such as Halloween. Any of a variety of different types of structures or methods can be practiced in the present invention to modify the graph 220 of the mat 100 and the present invention is not limited to any particular methodology or structure for modifying the graphs 220. Additionally, all of the various possibilities contemplated to provide a modifiable graphic presentation on the mat of the present invention can be incorporated in either or both of the base portion and the insert portion. For example, the graphics may consist of preformed messages or art forms that can adhere to either the surface which defines the bottom of the recess 210, for example using an adhesive or a fastener assembly, for example a hook and loop assembly, or on the underside of the insert portion 300 so that, when the insert portion 300 is placed within the portion 200 of base, the graphic will be visible through a portion of transparent insert. Alternatively, a variety of different graphics can be stored within the mat 100 so that a user is able to selectively discover a particular graphic for presentation while the other available graphics remain covered within the mat 100. This type of selectivity is known in other media where selectivity is desired among a variety of different graphics within a common display panel. For example, boards with sports event advertising information are capable of selectively displaying a first particular message during a particular first period of time, and displaying a second message during a second period of time on the same information board.
A third possible alternative is to provide a modifiable screen on the mat. The presentation surface can be associated either with the base portion of the insert portion, for example either on the bottom surface of the recess 210 or attached to the bottom of the insert portion 300. A screen can be included on the front of the mat, on the back of the mat so that it can be seen through a transparent portion of the mat, it can be embedded in the mat, attached to the mat or it can be produced integrally in the mat. rug. For example, the screen may be comprised of a thin and small box of graphics that may be attached to an adherent portion or a base portion or any other constituent part of the mat. However, it is associated with the mat and a user can design and display his graphic for a certain purpose and can subsequently modify that graphic so that it is replaced with another graphic. For this purpose, a presentation surface such as a writing board that can be erased can be used. It is also contemplated that a modifiable electronic display surface such as, for example, a liquid crystal display may be provided. The screen can be connected to a computer and a computer-generated image can be displayed on the screen. In this way, the image displayed on the screen can be modified by generating a different computer image and displaying that computer image on the screen. The screen may be associated with the base portion 200, such as that which is included within the recesses 210, or it may be included in a lower surface, facing upward, of the insert portion 300. Alternatively, the screen can be produced integrally with either the base portion or the insert portion. The modifiable screen can use a plurality of different graphics that can be displayed in any one of a variety of manner on the screen. For example, graphs can be displayed in a generally fixed position on the screen or can be scrolled across the screen, with both exemplary methodologies showing multiple graphs either individually or in combination. Other alternatives for modifying the graphics 220 of the mat 100 include using light emitting polymers to generate and, therefore, change, the graph 220. The light emitting polymers can be applied, either joined or woven into the mat. The light-emitting polymers can be used in any portion of the mat 100, for example, either in the base portion or in the insert portion, or in any other portion of the different modalities for the mat. The light emitting polymers are known and described in the patents of E.U.A. 5,945,502, 5,869,350 and 5, 571,626, which are incorporated herein by reference in their entirety. Other options for a screen are the use of electronic ink or electrical paper. The electrical paper is available from Xerox and is described in the patents of E.U.A. 5,723,204, 5,604,027, 4,126,854 and 4,143,103, which are incorporated herein by reference in their entirety. Electric paper uses thousands of small electrically charged spheres, called Gyricon, each about the width of a human hair, to create pixels. The two-tone spheres are embedded within a plastic laminate filled with liquid that forms the surface of the paper. Each sphere, with a black half and a white half, rotates in response to an electric field. The fact that the spheres have the black side or white side up determines the formation of an image. Because there is no need to change the image again, and because the screen is not backlighting, electrical paper uses only a fraction of the energy used by conventional electronic displays. Electromagnetic pens and devices similar to printers can be used to obtain images on such paper. Electronic ink is available from E Ink Corp., at 45 Spinelli Pl. , Cambridge MA 02138. Electronic ink uses a micro-encapsulated micro-mechanical presentation system. Small microcapsules are retained between two plastic sheets to create pixels. Alternatively, the capsules can be sprayed on a surface. The result is a flexible presentation material. The thin capsules are transparent and contain a mixture of dark ink and chips with white paint. An electric charge is passed through the capsules. Based on the electrostatic charge, the paint chips float on the top or the rest on the bottom of each capsule. When the paint chips float on top, the surface appears white. When they are at the bottom and therefore under the ink, the surface appears black. Each of the two states is stable: black or white. A transparent electromagnetic grid lying on the surface of the sheet controls the shape of the image. The screen can be connected wirelessly, for example, to a computer and in this way you can use World Wide Web (the worldwide network), for example, a Motorola paging system. The text on all screens, if used on multiple screens, can be changed at one time by a single editor, through a web page. Again, a presentation can be associated, which can use any of the methods discussed above to modify the screen, with any portion of the mat, such as the base portion 200 within the recess 210 or on a lower surface, facing upwards of the 300 insert portion. Alternatively, the screen can be produced integrally with either the base portion or the insert portion. The screen may be used in any of the embodiments described herein for the mat of the present invention, which include a mat that may include an adherent surface and a non-stick mat pattern. As mentioned above, in a base portion 200 that is described further, the base portion 200 may also include a component for water dissipation and a cushioning component. The water dissipation component provides moisture transfer from the soles of the shoes of a person standing on the mat 100, to reduce the degree of moisture transferred to the cleanable insert portion 300 and the cushioning component provides the conformation of the a mat 100 to the shape of the person's soles so that a greater amount of residue from the soles of the person's shoes can be removed by the mat 100. The present invention is not limited to any particular structure or material for the water dissipation component and the cushioning component. For example, the water dissipation component may be comprised of any of a wide variety of known materials such as polyamides, vinyl materials and polyisoprene. It is desirable, although not required, that the water dissipation component dissipate or move water and not retain water. Porous materials and non-hydrophilic materials are therefore desired. The cushioning component may be comprised of any of a variety of cushioning components to include, for example, foam rubber. Figure 2 also illustrates a portion 300 of cleanable insert. As can be seen, the cleanable insert portion 300 has a geometric shape which has a size and shape complementary to the recess 210 that occurs within the base portion 200. As such, the cleanable insert portion 300 is capable of being received safely within the recess 210. Therefore, the cleanable insert portion 300 has a length L2 which is just slightly smaller than the length Li of the recess 210. Similarly, the cleanable insert portion 300 has a width 2 which is also only slightly smaller than the width Wi of the recess 210. On the lower side 310 of the cleanable insert portion 300, ie, that surface contacting the surface which defines the lower part of the recess 210, a joining mechanism can be provided so that the cleanable insert portion 300 can be detachably attached to the base portion 200 within the recess 210. Any of a variety of different attachment mechanisms can be provided on the bottom surface of the cleanable insert portion 300 to include, for example, a hook and loop fastener assembly or an adhesive. Regardless of the particular attachment mechanism used to detachably attach the cleanable insert portion 300 to the base portion 200, in this embodiment, the cleanable insert portion 300 can be separated from the base portion 200 in a manner that can be cleaned by a user and, after cleaning, can be reinserted within the recess 210 so that a clean surface for the mat 100 is now provided. As stated above, the cleanable insert portion 300 can be manufactured from a transparent material such as hydrophilic aliphatic acrylic polymers and copolymers incorporating acrylic acid, hydroxyethyl methacrylate and glycerin monomethacrylate. The formation of the cleanable insert portion 300 of a transparent material will allow an individual to see the graphics for each purpose that can be provided within the mat 100, as discussed previously. Alternatively, the insert portion 300 may be opaque. Additionally, the upper side of the cleanable insert portion 300 may include an adherent surface.
The adhesive surface can be provided to help remove debris from the soles of the shoes of people standing on the cleanable insert portion 300. When the top adherent surface of the cleanable insert portion 300 becomes so dirty that the user wishes to clean the insert portion 300, in this embodiment, the user removes the insert portion 300 from the base portion 200 and cleans the 300 insert portion to eliminate accumulated waste. The insert portion 300 is then reinserted into the base portion 200. The adhering surface provided on the upper side of the cleanable insert portion 300 may be constituted of any of a variety of materials such as polyvinyl chlorides combined with a suitable plasticizer, plasticizer neoprene, polysulfides and polyurethanes. Additionally, acrylics such as butyl acrylate and many of its homologs can be used. Again, the present invention is not limited to any particular material. The adherent surface can generally be made of any adhesive material. In this mode, the only consideration is that the surface must maintain its adherent characteristic even after repeated cleaning cycles. The present invention is not limited to any particular methodology for the cleaning insert portion 300. The insert portion 300 can be cleaned by any of a variety of methods depending on the particular material composition for the insert portion 300. For example, the insert portion 300 can be cleaned by placing the insert portion into a washer and washing the insert portion 300 or the insert portion 300 can be cleaned by rubbing the insert portion 300 with a brush and soap and water or with a cleaning agent such as "Spic 'Span". Additionally, the insert portion 300 can be cleaned by using a roller that also includes an adhesive surface around the circumference of the roller. The adhesive surface of the roller is constituted by a stronger adhesive than that of the adhesive insert portion so that as the adhesive surface of the roller moves on the adherent surface of the insert portion dirt and debris from the insert portion Adherent will be captured by the adherent insert portion and will adhere to the roller. In this way, a roller with an adherent surface can be used to clean the adherent insert portion. However, again, the present invention is not limited to any particular methodology or cleaning agent for cleaning the insert portion 300 and any cleaning methodology or any agent compatible with the composition of the insert portion 300 is contemplated. The mat 100 may also include additional features to assist in cleaning the soles of a person standing on the mat 100. For example, the base portion 200 or the insert portion 300 may include an antibacterial composition and an antifungal composition . Antibacterial compositions such as anthraquinone derivatives of monomethacrylate and polyethylene glycol dimethacrylate can be used. In this way, the mat 100 can be bactericidal. The antibacterial feature may also be desirable particularly because the mat may be susceptible to cleaning both structural debris from the soles of people's shoes and also to remove any potentially harmful bacteria from the sole of people's shoes. Additionally, in order to additionally provide a desirable sole surface before entering a particular area, the mat 100 can also be provided with a fragrance. Flavones such as tricyclic molecules with aromatic substitution or organic ethers can be used, for example, liminolic acid. The fragrance is transferred from the mat 100 to the soles of people's shoes so that any undesirable odor is favorably masked by the fragrance. The present invention is not limited solely to using an antibacterial composition, an antifungal composition or a fragrance on the mat 100. Instead, the mat 100 can also incorporate a variety of additional substances that can assist in cleaning the soles of the shoes of the people. Any of a variety of structures or methods can be used to associate an antibacterial composition, an antifungal composition such as a fragrance or any other composition with the mat 100. The substances can be applied as releasable or dissipatable coatings to the 100 mat or can be embedded releasably, for example, as pellets within the structure of the mat 100 so that as pressure is applied to the mat 100, substances are supplied to the soles of people's shoes. Figure 3 illustrates an alternative embodiment for a mat 100. In Figure 3, it is illustrated that the base portion 200 may include separate layers for the water dissipation component 230 and a cushioning component 240. In this embodiment, the water dissipation component 230 is placed on the upper side of the cushioning component 240. However, the present invention is not limited to this particular embodiment for the water dissipation component 230 and the cushioning component 240. For example, a unique hybrid structure can be used for the base portion 200 that can include the material properties to provide both water dissipation and conformation structure. Alternatively, Figure 4 illustrates that the mat can include both a water dissipation component, or a wicking layer, and a water absorption layer. In Figure 4, the mat 400 includes a capillarity layer 410 and a water absorption layer 420. The capillarity layer 410 may be comprised of polypropylene or olefins, or any other suitable material having properties for the displacement of water from the surface of the mat 400. The water absorption layer 420 is placed below the capillarity layer 410. and absorbs any water that passes through capillarity layer 410. The water absorption layer 420 can be removed and dried periodically, for example in a drying machine. Of course, a capillarity layer 410 can be used with or without the water absorption layer 420, and a cushion layer can be used, as previously described in other embodiments, and the water absorption layer 420 it can be used with or without the capillarity layer 410 and a cushion layer. Additionally, both the capillarity layer and the absorption layer or the cushion layer can be used with or without an adherent portion. Referring back to Figure 3, Figure 3 also illustrates an alternative embodiment for the insert portion 300. Although the previously described embodiment for the insert portion 300 is discussed as a single structural member that can include an adhesive surface on an upper side thereof, the embodiment of FIG. 3 for the insert portion 300 is comprised of a plurality of layers. . As can be seen, the layers 301-305 comprise the insert portion 300. Each of the layers may include an adherent surface on the upper side thereof, as previously described for the insert portion 300. In use, the topmost layer, for example layer 301, can be separated from its adjacent lower layer, for example layer 302, and can be cleaned independently. After cleaning, the layer can be reinstalled within the recess 210 on top of the exposed layer of the insert portion 300. In this way, the insert portion 300 can be cleaned by removing an uppermost layer, cleaning said layer and reinstalling said layer within the recess 210. Although each layer is described as independently cleanable, neither is each individual layer required to be cleanable. Each layer can be made from materials as previously described when discussing the embodiments of Figures 1 and 2 for the insert portion. Other alternative embodiments are contemplated for the insert portion 300. For example, although the embodiments described previously have an insert portion 300 formed of one or more layers with an adherent surface on the upper side of one or more of the layers, it is not required that the insert portion 300 be constituted with only one adherent surface on the upper side of it. More specifically, an alternative embodiment for the insert portion 300 includes producing an insert portion 300 as a single structural member from a material which is adherent in the composition throughout the entire cross section of the material. A material such as a combination of non-crosslinked hydrophilic thermoplastic, preferably a polyethylene glycol diacrylate with n not exceeding 15, and a hydrophobic material, such as polyvinylneoprene chloride, can be used for the insert portion of this embodiment. By producing the insert portion 300 from an adherent and uniform material, the insert portion 300 does not necessarily need to be removed from the recess 210 of the base portion 200 to be cleaned. The insert portion 300 can be cleaned in this alternative embodiment by eroding the upper surface of the insert portion as a result of the use of the insert portion. In this way, by providing an erodable insert portion, the insert portion can be cleaned by erosion of its upper surface as the insert portion is used within the mat 100. As the insert portion 300 is eroded, the exposed surface of the insert portion 300 continues to be of an adherent composition due to its uniform cross section. As the exposed adherent surface is eroded, the dirt retained by the exposed adherent surface will dissipate as a result of erosion and therefore erosion of the insert portion itself provides a cleanable insert portion. Alternatively, even with a uniform cross section of an adherent substance for the insert portion 300, the user can remove the insert portion 300 from the recess 210 and can separately clean the insert portion 300. In this way, the user is not required to rely solely on the erodible feature of the insert portion 300 for cleaning said insert portion 300.; Rather, the user can use the erodible cleaning feature of the insert portion combined with a separate cleaning step to remove the insert portion from the base portion and independently clean the insert portion. As discussed in the foregoing, the insert portion 300 may be comprised of a variety of materials including materials such as adherent plastics, paper or adhesives that may be cleanable and may or may not be erodible and reusable. If paper is used, the insert portion can be made as a single structural member or as a plurality of layers, as discussed previously. Additionally, the paper may include an adherent surface on the upper side thereof. The paper can be translucent, opaque or with color, and can include a graphic representation in it. As discussed above, it is desirable although the mat is not required to contain a water dissipation or absorption capacity. This capability is desired to help prevent the adherent surface of the insert portion from becoming excessively wet and therefore becoming slippery. Although it has been discussed that, in order to help prevent the user from slipping on the adherent surface of the insert portion, a water dissipation or absorption capacity must be included in the mat to reduce the degree of humidity on the substrate. Adherent surface, this is not the only structure contemplated to prevent the insert portion from becoming slippery. Alternatively, the adhesive insert portion itself can be manufactured to help prevent slippage. Figures 5 to 7 illustrate alternative embodiments for the adherent insert portion 300. Figure 5 illustrates the adhesive insert portion 300 including a grid pattern 320 of channels 322 that can be made of a non-stick material. The channels may be raised from the surface of the insert portion 300 or they may be in the same plane as the inner surface of the insert portion. By forming the channels of a non-stick material, even if the adherent material of the insert portion 300 becomes wet, the user can be helped to not slip on the wet and slippery adhesive surface of the insert portion by the presence of nonadherent surfaces which do not become slippery when wet. Figures 6 and 7 illustrate another alternative embodiment for the adhesive insert portion 300 including anti-skid particles 324, for example silicon or sand particles that extend above the top surface 330 of the adherent insert portion. It is desirable that the anti-skid particles be made of a material which does not become slippery when wetted and, however, is not required to be exposed from the adhesive surface. Even if the anti-slip particles are embedded within the adhesive surface, their extension above the top surface 330 of the adherent insert portion will provide a physical frictional limitation against the slippage of the soles of the shoes of a person who stands on the rug. Although Figure 5 illustrates the adhesive insert portion 300 which includes a grid pattern 320 of the channels 322 which may be comprised of a n-adhered material, and Figures 6 and 7 illustrate another alternative embodiment for the adherent insert portion 300 that includes anti-skid particles 324 which extend above the surface 330 of the adherent insert portion, these two alternative embodiments are not required to contain mutually exclusive features. For example, it is contemplated that the adhesive insert portion 300 may include both a grid pattern of non-stick channels and anti-slip particles, which are not specifically illustrated in the figures but which can be easily understood. Another alternative for supplying a slip resistant adherent portion is to include a plurality of anti-slip members, or patterns or projections extending upwardly through and slightly above the surface of the adherent portion. As can be seen from Figure 8, in this embodiment, the adhesive portion 300 is inserted into a base portion, which may be a water absorbent boundary 500 and includes a plurality of openings 342 therein. Each of the plurality of patterns 344, which extend upwardly from a base that is placed below the adherent portion 300, extend upwardly, through one of the plurality of openings 342. The end that is more upwardly of each pattern extends above the surface 340 that is located upstream of the adherent portion 300. As a person steps on the adhesive portion 300, the amount and placement of the drawings 344 is such that the adhesive portion is capable of removing the residues from the person's shoes and the drawings 344, at least one of which is stepped on. by the person, prevents the slippage of the person in the adherent portion 300 in case the adherent portion 300 becomes slippery when wet. Drawings 344 may be compressed when pressed so that the end that is most upwardly of the pattern is in the same plane as the surface 340 that is in the uppermost portion of the adherent portion 300. In this way, the drawing will establish contact with the person's shoes to prevent slippage but does not prevent contact between the person's shoes and the adhesive surface of the mat, which improves the cleanliness of the person's shoes. Therefore, there is a relationship between the distance at which the pattern extends above the surface that is higher up the adherent portion, and the susceptibility to compression of the pattern.; a relationship which provides the functionality discussed above. The drawings can be configured in any size and shape. Additionally, the drawings can be made of any material that is resistant to slippage when wet such as, for example, rubbers or plastics. The drawings may include slots therein to further assist in preventing a person from slipping on the adhesive portion. In the following discussion it will be understood that the "base portion" of the mat which is referred to in the following mainly with the reference number 200, comprises at least a base portion of the lower layer and a non-adherent layer. At least one section of the non-adherent layer can be separated from the base portion of the lower layer. It should be understood that the base portion can be a single layer or multiple layers insofar as they cooperate properly with the adhesive insert. In consideration of the foregoing, Figure 9B is an exploded view of the mat, according to another additional embodiment of the present invention. The mat includes a base portion of the bottom layer 2300 which is formed as a substantially flat sheet of material of a predetermined thickness and having an embossed boundary 2303 circumscribing the planar sheet. The sheet of material includes a substantially planar surface 2302. The material can be a flexible, durable and water resistant material such as vinyl, plastic or rubber, shaped in the desired configuration, for example, by compression molding, injection molding, thermoforming or other process. The base portion of the lower layer includes an area 2301 configured to receive the adherent insert 2306. The area 2301 may be bounded by a border 2302 of material higher than the surface 2302. When placed within the area, the adhesive insert may be contacting a section of boundary 2303 embossed so that the edge and boundary cooperate to retain the adherent insert within the base portion of the bottom layer. The base portion of the bottom layer includes anti-slip components 2309 in the area 2301. The anti-slip components extend through openings 2307 in the adhesive insert and also help to fix the base portion of the bottom layer in place. In Figure 9B there is further shown a non-adherent layer 2304 of a predetermined thickness configured to be received within the base portion of the lower layer 2300 within the boundary 2303. A portion of the non-adherent layer can be permanently bonded to the base portion of the lower layer. The boundary 2303 may be shaped as a "concave molding" where, as shown in the cross-sectional view of FIG. 9A, beginning at an outer edge 2303.1, the boundary material has an upward and inward slope. An inner edge 2303.2, that is, a difference in height between the flat surface 2302 and a portion of the raised boundary may be substantially equal to the thickness of the non-adherent layer 2304. The non-adherent layer has a cutout area 2305 that conforms to the shape of the adherent insert, so that when the non-adherent layer and the base portion of the lower layer are placed together, the edges of the trimming area contact or are in contact with each other. adjacent to the edge 2308, and the upper surface of the non-adherent layer is larger than the surface of the area 2301 to receive the adherent insert. In this manner, the base portion of the lower layer together with the non-adherent layer form a base portion having a recess configured to receive the adhesive insert. The non-adherent layer 2304 may have properties of components of the base portion 200 described above. For example, non-adherent layer 2304 may have any, water absorption properties combination, water dissipation properties, water capillarity properties, cushioning properties, antibacterial properties, a fragrance, graphics and the like, as described above in relation to the base portion 200. The non-adherent layer can be, for example, a carpet. The area of a top surface of the non-adherent layer may be at least as large as the area of the top surface of the adherent insert. The areas of the upper surfaces of the non-adherent layers and the adhesive inserts can be respectively of such a size that the full sole of an adult shoe can be received thereon. As discussed in the foregoing, the adhesive insert 2306 may comprise a plurality of separable layers. The layers may comprise a flexible and pliable material such as polyethylene, biaxially oriented polypropylene or polyester film coated with a pressure sensitive adhesive to provide adhesion. A user of the mat can discard an insert layer which has become too dirty to effectively clean the shoes, to expose a new layer underneath the previous one. To facilitate detachment of a soiled layer, at least one section of the non-adherent layer 2304 can be detachable from the base portion to expose a detachment tab 2400 facilitates easy detachment of a layer of the adherent insert by allowing a user hold the release tab and in this way apply a separation force to the layer. The detachment tab 2400 can be made of the same material as the adherent insert during a die cutting process, discussed in greater detail in the following, but without any adhesive, which allows for easy handling. The detachment tab can alternatively be made of a different material and can be attached to the adhesive insert. A recess 2401 may be produced in the base portion of the lower layer to accommodate one or more of the release tabs. A pull tab 2402, for example in the form of a fabric loop, can be provided at an edge of the non-stick layer to allow a user to separate a section of the non-stick layer from the base portion of the bottom layer. The detachable section of the non-adherent layer can be attached to the base portion of the lower layer by easily detachable fasteners, for example, snap fasteners, as shown in Figure 10A, when in normal use. In Figure 10A, pull tab 2402 includes a receptacle component 2403 of the snap fastener, while the base portion of the bottom layer includes a matched male component 2404. While the mat is in normal use, the non-adherent layer lies flat on the base portion of the lower layer 2300, placing the two clamping components under pressure in immobilization coupling, fixing the separable section of the non-adherent layer to the base portion of the lower layer and by hiding one or more of the detachment tabs 2400 to provide a mat with an aesthetically pleasing appearance. In an alternative embodiment, as shown in Figure 10B, the fasteners can be hook and loop fasteners, such as VELCROMR and the like. In Figure 10B, a strip 2405 of VELCROMR attached to the underside of the non-sticky layer 2304 and a matching VELCROMR strip 2406 is shown attached to the flat surface 2302 of the base portion of the bottom layer 2300. While the The mat is in normal use, the non-adherent layer lies flat on the base portion of the lower layer 2300, keeping the two VELCROM strips in contact, fixing the separable section of the non-adherent layer with the base portion of the layer bottom and by hiding one or more of the detachment tabs 2400. As an alternative to the detachment tab 2400 extending within the area of the base portion of the lower layer covered by the non-adherent layer so that the detachment tab is hidden., the detachment tab can extend into the area 2301 of the adherent insert, as shown in Figure 10C. The tabs can be numbered to indicate to the user, for example, how many layers of adhesive inserts have been used. Figures 10D and 10E show side elevational views of the detachment tabs 2400 corresponding to the case where the adhesive insert comprises a plurality of layers. As shown in Fig. 10D, the release tabs can be stratified in a graduated manner, so that one edge of an upper tab extends beyond the edge of the tab that is below the previous one. Such a distributor may allow easier handling of a detachment tab. Alternatively, the tabs may be coextensive, as shown in Figure 10E. As indicated in the above, an adhesive insert may comprise a plurality of separable layers. Figure 11A is a side elevational view illustrating a possible sequence of layers in an adherent insert. In the example of Figure 11A, the adhesive insert has 12 layers, but clearly, it is readily contemplated that the adhesive insert may have more or fewer layers. In Figure 11A, each of the layers 1-12 comprises at least one adhesive layer and one film layer. The adhesive layer provides the adherent surface of the adhesive insert for cleaning the shoes, as described above, when it is exposed for use. The film is a means for the adhesive layer. In addition to the adhesive and film layers, the upper layer 1 and the base layer 12 each include a release layer. The release layers have a non-sticky outer surface (i.e., the surface opposite the surfaces in contact with an adhesive layer) that allow a group of layers that can be easily packaged, unpacked and handled by a user. The release layers are easily separated from the adhesive layer when a user needs to install an adherent insert on a base portion of a mat. To install a multi-layered adhesive insert, as shown in FIG. 1A, a user must peel off the base release layer from the layer 12 to expose the adhesive of the base layer. Then install the adhesive insert on the base portion of the mat. The adhesive of the base layer should fix the adherent insert within the base portion. The user then removes the top release layer to expose the adhesive surface of the first layer for use. After the first layer has been soiled by use, the user can remove the first layer to expose the adhesive surface of the second layer and can use said second layer. The bond between the adhesive surface of a layer and the film of the layer above it must be strong enough to ensure that the top layer does not come off easily from the bottom layer or from several layers when used to clean the shoes , but should not be so resistant that the top layer is difficult to remove by deliberate manipulation and application of force for that purpose. When all the layers of the insert have been used, the user can remove the base layer and install a new insert. Figure 11B illustrates an alternative embodiment of a layer of an adherent insert. As shown in Fig. 11B, a layer of an adhesive insert may comprise an adhesive 2700 interspersed with an integral anti-slip material 2701, which is superimposed on the film layer. The anti-slip material can be spread on a strip through the layer as shown in Figure 11C. This integral anti-slip material can be used to perform an anti-slip function in replacement of the anti-slip components of the lower layer of base mat, which is received through the openings in the adherent insert. Alternatively, both the integral anti-skid material and the anti-slip components received in the openings of the adhesive insert can be used to provide an anti-slip function. Now, a method and apparatus for the manufacture of an adhesive insert comprising a plurality of layers will be described. A basic material for producing the layers can be low density polyethylene, biaxially oriented polypropylene or polyester film manufactured and distributed in bulk quantities in units or in continuous rolls. The basic material can also be provided in the form of individual sheets, typically, the film is fed from the rolls and sent through a series of automated and mechanized laminating processes involving the application of adhesive to provide an adherent surface, the application of the release layers to facilitate packaging and handling, and cutting the layers to the desired shape. Referring now to Figure 12, the method of producing the adhesive inserts includes forming a top adhesive layer on a film, as shown in block 2800. The top adhesive layer can be produced by known methods, for example using a machine reverse roll coater or an engraving coater in a roll-to-roll process. The film with an upper adhesive layer constitutes a standard coating material for layers of the adherent insert, which are included in all the layers that are subsequently formed. Then, by using a laminator, a portion of the standard layer material is laminated with a release film in the top layer to form a top layer material to form a top layer of an insert, as shown in block 2801 This upper layer corrnds to layer 1, as shown in Figure 11A. A base layer material for forming a base layer of an insert is made from a portion of the material of the standard layer by the use of a reverse roll coater or etching coater, for example, by adding an adhesive layer of base next to the film opposite to the side with the top adhesive, and when using a laminator to laminate the base adhesive layer with a base layer release film, as shown in block 2802. This base layer corrnds to layer 12, as shown in Figure 11A. The constituent standard layer, the top layer and the base layer materials of the adherent insert are then subjected to further processing by alternative methods according to the invention to produce adherent inserts, as illustrated in Figures 13A, 13B and 13C, rctively and as discussed in more detail in the following. According to a known method called "multiple stratification" (not illustrated), all the layers must first be joined in a multi-layered laminate which is then cut into adherent insert forms. However, this method suffers from the disadvantage that undesirable unions of the cut layers occur at the edges thereof. Therefore, to avoid the problem of bonding the edges, the adhesive inserts can be manufactured in a process involving a rotary die cutter according to at least three alternative embodiments of the invention. Rotary die cutters are well known in manufacturing techniques. However, the use of rotary die cutters in a method for forming a multi-layered structure, as shown in Figure 11A, is not known. Figure 13A shows an apparatus configured to cut adherent inserts using a rotary die cutter according to the invention. Many individual 2900 rolls (for example 12) are shown to feed the materials of the top layer, the standard layer and the base layer, respectively, to a laminator 2901 and then to a rotary die cutter 2903. The layers are fed in a continuous form known as a "band". A laminator is a known machine which is configurable to apply a predetermined amount of pressure and tension by means of the rolls to a plurality of bands so as to link the bands together with a desired binding force. For example, the laminator may apply sufficient pressure so that, once finished, the adhesive insert may not be easily separated in its constituent layers by usual handling, but not by too much pressure that the layers effectively fuse together and be difficult to separate by deliberate manipulation and application of force for that purpose. After the layers are joined by the laminator to form a 12-layer band 2902, they are processed by the rotary die cutter 2903. The rotary die cutter 2903 cuts the 12-layer adherent insert 2905 to a desired shape from the web 2902. A more detailed example of the rotary die cutter is shown in FIG. 14. A rotary die cutter typically comprises at least two substantially cylindrical drums 3000 juxtaposed in rotational directions and opposite each other. The drums rotate on the arrows 3002 driven by gears 3003. The outer surfaces of the drums include engraving blades 3001 which contour the desired shape to be trimmed from a band 3004. One shape of one of the drum surfaces is the image to the mirror of the shape on the opposite drum surface. In the case of adherent inserts, the contoured shape may be an arc shape, as described above. The drums are aligned and their rotational speed is adjusted so that the corresponding blades on the respective drums come into contact during rotation, trimming the desired shape of the web material. Alternatively, the engraving blades may only be in one drum, while the opposite drum has a smooth surface. Typically, a removal device (not shown) is used to separate the cut band material from the drums. Figure 13B shows an alternative configuration using a rotary die cutter. In Figure 13B, the adherent insert forms are first cut out of the basic materials for the respective layers, then joined by a laminator to produce the adhesive insert. The upper layer material is fed to a rotating upper layer rotary die cutter, # 1 rotary die cutter, which is used to cut an insert form for the upper layer. The standard layer material is fed to a second single-layer rotary die cutter, the # 2 rotary die cutter, which is used to trim the insert shapes for the standard layers. In the present example, 10 standard layer insert shapes are successively trimmed by means of the rotary die cutter # 2 in an intermediate stacker (not shown) before being laminated or together with the insert shapes of the top and bottom layer. base. The base layer material is fed to the base layer rotary die cutter, the rotary die cutter # 3, which is used to cut an insert form for the base layer. Then, the top layer, the standard layers and the graft forms of the base layer are rolled together from the laminator 2901 to produce an adherent insert 2905. Figure 13C illustrates a configuration wherein the insert shapes of their respective materials are cut before being joined by lamination, but where each layer of the adherent insert is cut to be in the form of an individual rotary die cutter. Figures 15A-15D show plan views of additional embodiments of an adhesive insert 3106 which can be formed by the method described above. Figures 15A-15D show a different kind of opening in the adhesive insert to receive anti-slip components of the base portion of the lower layer. While, in the embodiments of the discussed figures given in the foregoing, the openings are relatively elongated in order to receive elongated, "rib-like" anti-slip components, in Figures 15A-15D, the openings 3107 have a substantially circular shape to receive nodular anti-slip components, "similar to projections". The openings 3107 may have several arbitrary distributions, as shown in the figures. In addition, the shapes of the opening are not limited to similar shapes but may also have arbitrary shapes, such as oval, square, rectangular or triangular shapes. Returning to Figures 15A-15D, a detachment tongue 3100 is provided on an edge of the adherent insert. As with the detachment tabs 2400 described above, the release tabs 3100 can be made of the same material as the adhesive insert during a die cutting process, as discussed above, but without any adhesive, which allows its easy handling. The detachment tab can alternatively be made of a different material and can be attached to the adhesive insert. The location of the detachment tongue is arbitrary. The base portion of the lower layer may have a recess for receiving the release tab. In the preceding discussion, the term "insert" is used to refer to a member designed to be inserted into, that is, to be received by a recess of a base portion. As discussed, the insert can be a single layer of material having a top stacking surface (and possibly a non-stick release film on its underside), or it can comprise a plurality of separable layers, each having a surface superior adherent (and possibly a non-adherent release film on an upper layer and on the underside of a base layer). The following discussion uses the term "insert" to refer to a single layer form. Therefore, what is referred to in the above as an "insert comprising a plurality of separable layers" (eg, as shown in Figures 10D and 10E, should be understood in the following discussion which corresponds to a "plurality of separable and stacked inserts. "If the inserts are stacked, it can be difficult to separate one insert from another when its respective release tabs (hereinafter referred to simply as" tabs ") have smooth surfaces. The tabs are smooth, they can tend to stick together due to cohesive attraction.When the tabs stick together, it can be difficult, for example, to hold the tongue of the uppermost insert in a stack of inserts to separate it from the stack. handles an insert to try to separate it from the stack, the tabs that have been stuck together may tend to cause more than one insert to separate poured from the stack, wasting material. A solution is needed to solve these problems. Accordingly, the embodiments of the present invention relate to providing a non-smooth texture for a tongue of an insert, or to add thickness to a portion of a tongue, so that it is more easily able to separate one tongue from another and consequently of more easily separating an individual insert from a stack of inserts. The term "non-smooth texture" (rough texture) means that at least a portion of the surface of the tongue includes areas of differentiated height, i.e., areas that are raised or lowered as compared to a total tongue surface, so that the portion is substantially non-planar. For example, the portion can be characterized as being "projecting" or "rough" compared to the rest of the tongue surface. In a modality, a non-smooth texture can be applied to a tongue material using heated textured rollers. More specifically, as described above, the tongue material can be made of the same material as the insert during a troque cutting procedure, but no adhesive is applied to the material used for the tongue. The tongue material can be laminated between the textured and heated rolls (a process that can be termed "thermoforming") to impart a non-smooth texture to the tongue material. "Textured" rollers mean rollers having protruding portions on their outer surfaces so that when pressure and heat are applied from the rollers to the tongue material, said projections on the rollers are printed on the tongue material. The shape of the projections is arbitrary. In such an operation, the temperature of the rolls typically needs to be or be close to the glass transition temperature (Tg) of the tongue material. Depending on the feed rate of the reed material to the reels, the amount of pressure that can reasonably be applied to the reed material and the thermal losses, the reels may need to be heated to a temperature above the Tg of the reagent material. tongue. Although thermoforming can be performed with almost any thermoplastic material, the process is typically easier with materials with a lower Tg such as polyethylene or polypropylene. However, any suitable material is within the scope of the present invention, and the present invention is not limited to the use of polyethylene or polypropylene. As indicated in the above, the tongue material can be formed from the same material as the insert; that is, low density polyethylene, biaxially oriented polypropylene or polyester film manufactured and distributed in bulk quantities in units of continuous rolls. The processing of non-smooth textures in the tongue material can be done before a laminating step that applies adhesive to the film to make a standard material for each adhesive insert. Thus, for example, the processing of non-smooth textures can be carried out by pretreating the entire roll or film in a thermoforming step before the rolling step, or it can be done by adjusting the thermoforming rolls as part from a line of laminate, at a point on the line before applying adhesive. The approach of applying a texture that is not smooth to the tongue material before lamination with adhesive is potentially more cost effective. Although the application of a non-smooth texture is possible after the adhesive has been applied, this presents the risk of sticking the rollers if the adhesive is not well controlled (keeping the area of the tongue completely clean). After a roller of material has been treated as described above, the individual inserts, including tabs having a non-smooth texture, can be cut out of the roll in a die cutting process and can be stacked. Alternatively, multiple bands can be stacked and then the stacked inserts can be cut out by punching the stacked bands. As an alternative to using the thermoforming rolls to apply a texture that is not smooth, a corrugation tool can be used to introduce a non-smooth texture into a tongue material. Corrugation can be performed more easily if the corrugation tool heats up or if the tongue material is heated to a temperature close to the Tg of the material. However, heating is not necessarily required, if an adequate force is applied to the corrugation tool. According to another alternative, a non-smooth texture can be applied by placing a tongue material in a heated press, either before or after the die cutting of the individual inserts of a material roll. In a further alternative, a non-smooth texture can be applied to a tongue material by joining particles, such as sand or gravel, to a surface of the tongue material. It may be advantageous at some point in the manufacturing process of the insert to introduce a waviness in the tabs to promote the fan opening of the tabs, which may also make the separation of the individual tabs less problematic. In view of the above description, finally a mat insert according to the embodiments of the invention can comprise an adherent area and a non-sticky area, a portion of the non-sticky area can be made as a tab for holding the insert and a surface of the tongue includes a non-smooth texture. A non-smooth texture may be applied to one or both sides of a tongue material as described above. It can be appreciated that although the application of a non-smooth texture to a tongue material in the manner described above can generate raised areas or projections in relation to a tongue surface, relative to the opposite side of the tongue surface, the Enhanced areas or projections can be recesses or slots. On a given side, the non-smooth texture of the tongue may comprise, for example, small projections, grids or random roughness of the surface. Some examples of possible non-smooth textures are shown in Figures 16A-16C. Figure 16A shows a plan view (ie, a view from the top) of a pattern of substantially square or rectangular protrusions or projections. The height of the projections in relation to the rest of the surface of the tongue depends on the thickness of the tongue material and the texture roughness desired. The height of the projections, measured from an area of the tongue surface where a non-smooth texture has not been applied, can be, for example, from about 5% to about 50% of the thickness of the tongue material before thermoforming. More specifically, the height may be from about 10% to about 30% of the thickness of the tongue material. The area of protruding portions, when viewed in a plan view, may correspond, for example, with the length from about 0.1 mm to about 2.0 mm on one side. More specifically, the area may correspond to a length from about 0.5 mm to about 1.0 mm on one side. Figure 16B shows a plan view of a pattern of substantially circular protrusions or projections. The height of the projections, in relation to the rest of the surface of the tongue can depend on the thickness of the tongue material and the desired texture roughness. The height of the projections, measured from an area of the tongue surface where a smooth texture has not been applied can be, for example, from about 5% to about 50% of the thickness of the tongue material before thermoforming. More specifically, the height may be from about 10% to about 30% of the thickness of the tongue material. The area of the projections, when viewed in a plan view, may correspond, for example, to a diameter of about 0.1 mm to about 2.00 mm. More specifically, the area may correspond to a diameter of about 0.5 mm to about 1.0 mm. Figure 16C shows a random distribution of a non-smooth texture. The dark lines indicate areas on a tongue surface that can be raised or lowered. The height (or depth) of the texture relative to the rest of the surface of the tongue may depend on the thickness of the tongue material and the desired texture roughness. The height (or depth of texture), measured from an area of the tongue surface where a non-smooth texture has not been applied may be, for example, from about 5% to about 50% of the thickness of the tongue material before More specifically, the height (or depth) can be from about 10% to about 30% of the thickness of the tongue material.The width of the raised areas or the recesses, when viewed in a view of plant can be, for example, from about 0.1 mm to about 2.0 mm More specifically, the width can be from about 0.5 mm to about 1.0 mm.As discussed above, a non-smooth texture can be applied to one or both sides of a tongue material In accordance with the embodiments of the invention, if a non-smooth texture is applied to only one side of the tongue, a non-smooth texture is formed so that when A first tab is distributed over a second tab so that it is substantially aligned with the second tab (for example in an array of inserts) the non-smooth textures of the respective tabs are deviated from each other. This is done so that the raised areas on a lower tab do not lodge within the corresponding recesses in an upper tab, which can make the tabs difficult to separate. Otherwise, the projections on a tongue do not fill the gaps in an adjacent tongue. An example of such a distribution is shown in Figure 17. Figure 17 shows a stack of insert tabs 1700. The projections 1710 are produced on a top surface of a top tab 1720 and therefore notches are formed corresponding to the projections 1710 on the opposite surface. The projections 1730 that are formed on the tab 1740 below the tab 1720 are offset from the projections 1710 to prevent lodging within the notches. In a similar way, the projections 1750 on the tab 1760 below the tab 1740 are offset from the projections 1730. Although in figure 17 an example of three tabs is shown, such a pattern of deviated non-smooth textures can be repeated through a stack of inserts of an arbitrary amount. The formation of non-smooth textures deflected as described above can easily be carried out by orienting upper and lower rollers, in a thermoforming process in such a way that the housing does not occur when the stacking of the tongues is performed. Another possibility is to use different non-smooth texture patterns on adjacent tabs, so that the coupling or housing can not be performed. For example, in a stack of inserts, the tabs with a non-smooth texture in a regular pattern, as in Figures 16A and 16B, may alternate with tabs having a non-smooth texture randomly distributed, as in Figure 16C. Alternatively or additionally, the adjacent tabs may be distributed so that their facing surfaces have only areas raised one in relation to the other, or that both have only one recess in relation to each other so that the fitting can not be performed or accommodation. Figures 18A-18C illustrate further embodiments of the present invention, to facilitate the ease of tab separation in a stack of inserts with each other. Figures 18A-18C are side elevational views of the insert tabs extending from an adherent portion of the inserts. In Figures 18A-18C, each of the tabs 1810 has a first portion and a second portion, wherein the first portion is thicker than the second portion. According to the embodiments, the first thicker portion can be made by a separating material 1820 that is added to a surface of the tongue material. The spacer material causes the second thinner portion of the tongue (i.e., the portion without the added spacer material) to separate from the second thinner portions of adjacent tongues. That is, in an array of inserts where the tabs are substantially aligned with each other, the first thicker portion generates a space between the second thinner portion of the adjacent tabs, which allows easier separation of the tabs. In other words, according to the embodiments a first portion of the tongue is thicker than a second tongue portion so that when the first tongue is distributed over a second tongue so that it is substantially aligned with the second tongue, the second portion of the first tab is separated from the second portion of the second tab. The place where the separator material is placed is arbitrary. For example, Figure 18A shows the spacer material 1820 that is aligned with the outer edge of a tongue 1810. Figure 18B shows the spacer material 1820 that is located around the center of a tongue 1810. Figure 18C shows the spacer material which is close to a region demarcated by line 1840 where the surface of an insert becomes adherent. According to the modalities, the separating material can be made from the same material as the tongue. For example, the spacer material may be an additional film layer attached to the tongue. Alternatively, the spacer material may be made of a material different from that of the tongue and may be attached to the tongue. In any case, the bond can be implemented with adhesive, it can be implemented thermally or chemically, or it can be implemented with a fastener such as a staple or staples. As another alternative, the spacer material may be a staple, washer, rivet or other means for producing a projection or projection on the tongue. Such staples, washers, rivets or other means to form a projection may be, for example, plastic, rubber or metal. According to embodiments, the spacer material can be added to alternating tongues in a stack of inserts. The spacer material may be provided with some kind of visual indicator, such as color, on selected tabs. For example, the penultimate or the last tab, in a stack of inserts. Or, the spacer material may be distributed to differentiate each tongue from another, by some kind of structural or visual indicator. For example, the tabs in a stack of inserts may have alternating colors, or each may have a different color. Each tab in an insert stack can be numbered or a letter can be applied, for example in a recognized sequence such as (1, 2, 3 ...) or (A, B, C ...). In an alternative embodiment, each tab may have an extension projecting beyond the outer edge of the tab, as shown in FIG. 19A. Figure 19A shows the tabs 1900-1905, each with a respective extension 1900E, 1901E and so on. The extensions may be distributed such that, when a first tab is placed on a second tab so that it is substantially aligned with the second tab, the extensions of the respective tabs are offset from each other. Figure 19B illustrates the above. Figure 19B shows tongues 1900-1905 distributed so as to be substantially aligned with each other, for example, as would happen in a stack of inserts. Each respective tab extension 1900E-1905E, on the other hand, is deviated from the other extensions. The tongue extensions as shown in Figures 19A and 19B can be made, for example, by die cutting or by adding the extensions to the tongues in a separate procedure. The tongue extensions can be made from the same material or from a different material than the tongues. According to another embodiment, heat can be applied to the tongues so that the tongues shrink or expand one relative to another. The differentiation between the tabs in this way may allow an easier separation of the tabs. In one embodiment, heat can be applied to tabs of similar material and thickness, but the degree and duration of applied heat can vary between the tabs. That is, a first tongue may have heat of a first degree and duration applied thereto, while a second tongue may have heat of a second degree and duration, different from the first, applied to it. Due to the difference in the degree and duration of the heat applied to the first and second tongues, they will expand or shrink differently from each other. Thus, if the first and second tongues are distributed adjacent to each other in a stack of inserts, they can easily be separated from each other, because they have different sizes. Alternatively, tabs of similar material but of different thicknesses can be made, and the same degree and duration of heat can be applied to the tabs. That is, a first tongue will have a first thickness. A second tab can have a second thickness different from the first and the heat of the same degree and duration can be applied to the first and second tabs. Due to the difference in the thicknesses of the first and second tongues they can expand or shrink one in relation to the other. Therefore, if the first and second tabs are distributed adjacent to each other in a stack of inserts, it will be easy to separate them from each other, because they have different sizes. According to another alternative, tabs of similar material but having a different film orientation can be made. The term "film orientation" refers to a property of the film at the molecular level; for example at the molecular level, a film can be "bioriented" or "biacted". As those skilled in the art know, films with different orientations respond differently to heat. For example, a film with a first orientation may have a tendency to expand or shrink, when heat is applied to it, in a different direction to another film having a second orientation different from the first when heat is applied thereto. This orientation property of the film can be useful for introducing differentiation between tabs. Thus, according to the embodiments of the invention, a first tab can have a first film orientation. A second tab can have a second} orientation different from the first, and the same degree and duration of heat can be applied to the first and second tongues. Due to the difference in film orientation of the first and second tabs they will expand or shrink differently from each other. Therefore, if the first and second tabs are distributed one over the other in a stack of inserts, they are likely to separate easily with each other, because they have different sizes. In a further alternative, tabs can be made that have completely different materials. For example, a first polypropylene tab can be made, while a second tab can be made of nylon. The same degree and duration of heat can be applied to the first and second tongues. Due to the differences in the materials, the first and second tongues can shrink differently one from the other. In this way, if the first and second tongues are distributed adjacent to each other in a stack of inserts, it will be easy to separate them from one another, because they have different sizes. In addition, tabs of different materials but having substantially the same thickness can be made, and the degree and duration of the applied heat can be varied between the tabs, as described above. This also results in the tabs having different sizes. It should be understood that any of the steps of the methods described in the above can be carried out in any combination to obtain a differentiation between the tabs. For example, the tabs may be of a similar material but of different thicknesses, and the heat of different degrees and durations may be applied to the respective tabs. Or, the tabs can be made from similar materials having different film orientations, and heat of different degrees and durations can be applied to the respective tabs. In addition, the tongues can be made of different materials and of different thicknesses, and different degrees and different durations of heat can be applied to the respective tongues. All of the embodiments described are illustrative of the various ways in which the present invention can be practiced. Additionally, any of the described embodiments may be combined with any other embodiment of the present invention and this invention is not limited solely to the particular combined modalities described. Other embodiments may be implemented by those skilled in the art without departing from the spirit and scope of the present invention. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
