The technical field to which the invention relates.

The present invention relates to an absorbent product having essentially no sticky back sheet, which has a high coefficient of friction and is designed to hold the product in place during use, and having at least one tab from samootravljenia tape designed for the placement of articles in a predetermined position in the underwear of the user and maintain the position of the product in the absence of any normal force applied to the product. Absorbent articles in accordance with the present invention include sanitary napkins, pads for underwear, protective devices used in case of incontinence, diapers, etc.

Background of invention

In many absorbent products, especially those designed and executed with a specific form for absorption of vaginal discharge and/or discharge from the urethra, is used positioning adhesive, bonding with pressure and deposited on the layer back sheet for secure attachment of items to the undergarment of the user. To protect the positioning of the adhesive prior to use, typically on top of the adhesive overlay sheet made with the possibility of separation. There are many disadvantages, is provided using a detachable sheet and positioning of the adhesive; some of these disadvantages is shown below.

Detachable sheets, usually made of paper coated with silicone, which represents an expensive component in the composition of the absorbent product. In addition, consumers believe that the ejection of the sheet after separation from the product causes inconvenience and attracts unwanted attention.

One approach proposed to address the need for a separate detachable sheet, is to apply a detachable coating on the film the outer wrapper and apply the product directly to the outer wrapper. In this approach, the cost is somewhat reduced due to the exclusion of discharge of the sheet, but remains the most expensive component, namely the covering itself. Another disadvantage of this approach is the need for external wrap. Many industrial manufactured and supplied to the market absorbent products are sold in bags or boxes, and thus, they are not separately Packed in an outer wrapper.

In U.S. patent No5217448 described absorbent article having side strips that can be used but are not necessary. Products have side wings coated with glue and the corresponding zone unpin turned on the lingerie side products designed on the I, to attach the wings with the possibility of release. This configuration eliminates the need to discharge the sheet that is intended to protect painted on the wings glue. The wings can be separated from the zone of detachment and attached to the undergarment of the user, but not necessarily. On facing the lingerie party products there are additional zones deposited adhesive, bonding with pressure, which are designed to maintain product position during use, especially when the wings are not used. However, the presence of zones positioning of the adhesive associated with other disadvantages. Part of the positioning of the adhesive may remain on the underwear of the user after removal of the absorbent product, this creates the possibility of accessing the remaining adhesive in contact with the skin of the user or discoloration of the underwear of the user without the ability to restore the original color. Alternatively the product may delaminate or break if you remove it, if the adhesive force of the adhesive with underwear above the strength of the connection, ensuring the integrity of the product. While there are problems associated with difficult or unhygienic separation and removal of parts remaining on underwear.

The use of positioning adhesive also what may cause irritation to the ordinary consumer and complaints it associated with what is known as "churning in clumps", while capturing absorbent products in lumps, they become inconvenient and increases the likelihood of peripheral leakage. This phenomenon occurs due to the forces created between the product and the adjoining parts of the body. In the process of churning in clumps positioning adhesive may stick to itself, creating a permanent crease or fold.

In order to exclude as positioning adhesives and detachable sheets, have been developed absorbent articles having a back sheet with a high coefficient of friction. This product is described in U.S. patent No5011480. Back sheet with a high coefficient of friction is a useful tool for maintaining the position of products in the underwear of the user when the underwear is situated next to the body, and in this position to the product of the applied normal force. When the underwear of the user is at some distance from the body of the user on the product are very small normal force, or these forces do not act on the product, and frictional properties of the rear sheet create minimal resistance to the displacement of the product. This provides the possibility of replacing the products or separation from his underwear, when the user urinates or just beginning to use the product for the first time. See what the earth can create problems with comfort and lead to the placement of the product in position, which will not be optimal for absorption of exudates. The Department may also lead to contamination of the product, the user will be forced to throw the product.

The invention

In accordance with this invention features an absorbent article containing permeable to liquid covering element, not essentially the sticky back sheet with a high coefficient of friction, having at least one tape pull-tab attached to its outside surface, and an absorbent material. The tape tab has a fixed end, a free end, a first surface and a second surface opposite the first surface. On the second surface of the tape tab has an adhesive zone and the zone of detachment. The tape tab may be bent so that the adhesive zones and zones unpin will be converted to each other before using the product. Such structural elements allow you to eliminate the need for any detachable sheet or discharge the coating on the wrap, as well as minimize the use of positioning adhesive. The tape tab contains the minimum amount of adhesive sufficient to maintain the product position, when the underwear of the user is removed from the user's body. When underwear is close t the La user, back sheet with a high coefficient of friction acts as the primary tool for maintaining the position of the product. In addition, the tape tab creates a hygienic and convenient means for placing and removal of the product, allowing to eliminate or reduce the number of situations in which the user needs to touch the part of the product that will be used for absorption of exudates.

In accordance with the present invention the above-mentioned absorbent product can be supplied in a wrapper, with part of the belt tongue goes outside to the wrap, which allows the user to open the wrapped product and to separate the product from the wrapper using ribbon tab.

A detailed description of the preferred embodiments

In accordance with the present invention is designed absorbent product intended for the treatment of produced by the body fluid-fluid containing a back sheet with a high coefficient of friction and at least one tape pull-tab extending from it. The tape tab contains a minimal amount of glue, bonding with pressure, and this number is sufficient to maintain the product position, when the underwear of the user is removed from the user's body. When underwear is near the user's body, the back sheet with a high coefficient of friction is used as the primary means for maintaining the position of the product due to normal forces acting on the part of the user's body and underwear. In this section, similar elements have the same numerical designation.

As shown in figures 1 and 2, in a preferred embodiment, the absolute is birouste product 10 has a transverse ends 11, the longitudinal sides 12, essentially, not the sticky back sheet 13 with a high coefficient of friction and two tape tabs 20A and 20b (denoted along the reference number 20). Back sheet with a high coefficient of friction is depicted in all the figures in the preferred embodiment, in the form of a framework having a floor 14, a deposited (described in more detail below).

Each of the two tape reeds 20 has a fixed end 21, the free end 22 of the first surface 23 and a second surface 24 opposite to the first surface 23. Each second surface 24 has an adhesive area 25 and area 26 unpin. Tape the tab 20A is shown in extended position in which it is ready for attachment to the undergarment of the user. The tape tab 20b is in the folded position, so that the adhesive area 25 and area 26 unpin are in contact with each other. Before using the tape tabs are in such folded position, with no part of the adhesive zones remains open to influence. This eliminates the need for separate detachable sheet, designed to protect the adhesive tape tabs, similar to what is used in many commercially available products.

Tape the tabs 20 may be manufactured from a number of materials, including woven fibrous materials, the ox is Kristie nonwovens, polymer film, paper, and combinations thereof. Preferably the tape tabs are made of olefin films such as polypropylene and polyethylene film, or polyester film. The tape tabs are suitable for the present invention, industrially manufactured and delivered to the market by companies 3M and Avery Denison.

Despite the fact that the tape tabs 20 shown in the figures in the form of reeds, having essentially a rectangular shape, other geometric shapes, suitable for use include oval, round and square shape. Can also be used asymmetric geometric configurations such as triangles. The dimensions of the strip 20 reeds usually are, within certain limits, while their length is from about 12.7 mm to about 101,6 mm, their width is from about 6.35 mm to about 38.1 mm, and their thickness ranges from approximately 0,0254 to approximately 1,016 mm

The tape tabs can be attached to the back sheet at a fixed end, and possibly but not necessarily, part of the first surface by any means known to the ordinary person skilled in the art. A particularly suitable method of attachment is the attachment by means of heat sealing and using adhesives.

Adhesive area 25 and area 26 ukrep is placed located on the second surface 24 of the belt tongue. Preferably the adhesive area 25 and area 26 unpin formed from the coating on the second surface. Each of the adhesive areas and areas unpin may consist of one continuous zone or, alternatively, from a variety of areas, arranged in a certain pattern. Figure 1 shows the adhesive area near the free end 22 of the belt tongue and the area check out near the fixed end 21 of the belt tongue. A small area 40 adjacent to the free end 22 is left uncovered in order to facilitate the bending of the belt tongue with its transformation from a folded position to an extended position. Nevertheless uncovered area should be made as small as possible in order to minimize any tendency of lifting the free end up in use, which could potentially increase the likelihood of discomfort to the user.

The adhesive area 25 can contain any of the known adhesives, bonding with pressure. In a preferred embodiment, the adhesive area 25 is a continuous area with a coating, deposited by extrusion, and containing a block copolymer of styrene. Suitable materials for the zone 26 unpin include wax (paraffin) and silicone, but are not limited to these materials. To cover the tape reeds can be used is the means of extrusion and printing.

Figures 1 and 2 show a preferred variant implementation of the absorbent product 10, in which the tape tabs 20 are located near the transverse ends 11 and held in a direction essentially parallel to the longitudinal sides 12. In an alternative embodiment, shown in figure 3, two tape tabs are located near the longitudinal sides 12, and they are given such a configuration that they are in a direction essentially parallel to the transverse ends 11. The tape tabs, similar to that shown in figure 3, can be wrapped around the perineal part of the underwear of the user and glued or each other, or to the outside surface of underwear.

As shown in figure 4, in another embodiment, the present invention uses the tape tabs 20, which, when stretched to its full length, located within the periphery of the product 10. With this arrangement, the belt of reeds to exclude their contact with the user's body, thereby minimizes any potential discomfort that could be caused by lifting belt reeds up and/or wearing them while driving.

In the variants of implementation in which multiple tape reeds are very close to each other, as shown in figure 3 and 4, the fixed end 21 of the tape p is ccov 20 may be a continuous strip of material, having two free end 22. In this case, the definition of "continuous" includes two separate element in contact with each other and attached to each other, and elements manufactured as a single element.

Scope of the present invention also includes embodiments of which the number of tape reeds larger of the two, with the tape tabs are from many points on the periphery of both parallel and at an angle relative to the transverse ends and longitudinal sides. However, the purpose of the tape 20 reeds is to provide only temporary fastening products to the undergarment of the user in those moments when the underwear of the user is removed from the user's body, for example, before use of the product and during urination. When underwear is near the user's body, essentially, not the sticky back sheet 13 with a high coefficient of friction is used as the primary means for maintaining the position of the product. By "essentially non-sticky and easy" sheet in this case refers to the material, giving a value of less than 100 grams when tested it on the test device with an inverted probe, such as Probe Tack Tester model number 80-02 supplied by the company Testing Machines Incorporated, Mineola, long island, new York, using standard methods tested is th ASTM D-2979-95 (ASTM - American Society for Testing Materials American society for testing and materials).

Back sheet 13 preferably has a static friction coefficient greater than approximately 1.0, and the dynamic coefficient of friction greater than approximately 0.8 when measured it using the standard test methods ASTM D-1894. Despite the fact that as the basis for the test ASTM D-1894 can be used a number of materials, it is preferable to cotton. In particular, we used the single fabric weave, containing 30/1 combed and deparaffinizing one hundred percent cotton with a drawing ratio 162; cotton fibers were subjected to chlorine bleaching, representing the finishing process.

Back sheet 13 may be a base, such as a nonwoven material, polymeric film, the microporous film or the like containing essentially no sticky coating with a high coefficient of friction drawn on it. This coating preferably has a glass transition temperature (transition in glassy state) less than -15 degrees Celsius. The glass transition temperature is a temperature at which the maximum tangent loss (tan δ or G"/G') occurs in the measurement of dynamic modulus of elasticity as a function of temperature by use of a spectrometer is La mechanical spectroscopy (frequency-temperature dynamic studies of mechanical losses), such as a Rheometrics RDAII supplied by the company Rheometrics Inc., Piscatoway, New Jersey. The coating also preferably has a dynamic modulus of elasticity shear (G') in the temperature range from about -40 to about 50 degrees Celsius (the temperature range applications)exceeding 1×105Dyne per square centimeter (1 N/cm2). This combination of high friction coefficient and modulus of elasticity and a low glass transition temperature and stickiness allows you to get back sheet, which agrees well with the area to which it is applied, while it is slightly shifted or not shifted and not "break into lumps" in use and can easily be separated for removal.

Suitable materials for producing essentially no sticky coating with a high coefficient of friction industrial manufactured and are available on the market and include adhesives 195-338 supplied by the company ATO-Findley, and 34-3396 supplied by the company National Starch and Chemical, but are not limited to these adhesives. The coating can be applied in the form of a melt. Preferably, the surface density of the coating is from about 1.55 to approximately 15.5 milligrams per square centimeter. The coating can be applied so that it will cover located outside the rear surface of the base sheet, or alternatively, the coating can be applied in the form of a drawing, as seen in the figures. In one embodiment of the present invention, the coating can be applied by use of a device for applying a foamed hot melt adhesives, such as an applicator FOAMMELT or FOAMMIX supplied by the company Nordson Corporation, Amherst, Ohio.

Another variant of implementation of the present invention includes a back sheet 13 in a base containing fibers, cut in the form of a short NAP. The cutting of the fibers for a short NAP is known in the production of fibers. See, for example, U.S. patent No No 2257501, 2691611, 3436442 and 3672929. Representative, non-limiting list of suitable fibers include cellulose chemical fiber, polyester fiber, ultra-high absorption capacity, nylon fiber, polyvinyl alcohol fiber and acrylic fiber. Preferred fibers include polyester fibers with weight room fibres from 6 to 15 denier (6,67 to 16.67 decitex), such as supplied by DuPont Company, polymer fibers with ultra-high absorption capacity, such as supplied by firms Technical Absorbents Limited and CAMELOT. The person skilled in the art can appreciate the fact that on the back sheet 13 may be used a mixture of fibers of different types.

Back for the second sheet 13 with a high coefficient of friction may be in the form of one-component layer, for example, natural rubbers, olefin rubbers, and examples of the material for this layer is polyethylene obtained by metallocene catalyst.

As shown in figure 2, the absorbent article 10 also contains permeable to liquid covering element 30, which is directed towards the body when using. The covering element 30 is preferably pliable, creating a feeling of softness and not irritating the skin of the user. In addition, the covering element must have a good capacity for transmission fluid and a reduced propensity for re-wetting, which allows the secretions from the body quickly enter it and go through it in the direction of the next, the underlying layer, and the covering element does not allow such discharge to pass back through it to the skin of the user.

Suitable covering element 30 may be manufactured from a wide range of materials, including woven and nonwoven materials, molded polymer film with holes, films produced by hydroforming, porous foam, reticulated thermoplastic films and thermoplastic scrims (gauze materials), but suitable materials for the formation of the covering element 30 is not limited to the above. In addition, covering the element is provided may be made from a combination of one or more of the above materials, for example in the form of a layer of composite material from a nonwoven material and a molded thermoplastic film with holes.

Film with holes suitable for the formation of a covering element (30), because they are permeable with respect to liquids, and, if the holes in them correctly (including giving them taper), the films possess a reduced tendency to allow liquids to pass back through them and cause re-wetting of the skin of the user. Suitable films are described in the following U.S. patents NoNo 3929135, 4324426, 4342314, 4463045 and 5006394.

In addition, the absorbent article 10 includes an absorbent material 31 that is designed for the treatment of absorbed fluid medium and holding her. Representative, non-limiting list of absorbent materials suitable for the present invention include natural cellulose, such as cotton and wood pulp, regenerated cellulose, such as the hydrated cellulose fibers and cellulose acetate, peat moss, forming a hydrogel polymers in the form of fibers or particles, usually called "superabsorbents", etc. the person skilled in the art can easily understand that to optimise the performance of absorbent articles used in different conditions, can be used in esavana a mixture of two or more types of absorbent materials. The absorbent material may be distributed evenly, or, alternatively, may be located in separate structures, or structures with directionally varying properties.

Figure 2 shows the absorbent material 31 in the form of absorbent Central part, that is, a single layer, located between the permeable for liquids covering element 30 and the back sheet 13. Alternatively, permeable to liquid, the covering element 30 or the back sheet 13 can contain absorbent material inside their structure or on one or both of their surfaces in the form of a structure of a composite material.

Absorbent Central portion of the structure may include a mixture of absorbent material and thermoplastic fibers, for example, to impart structural integrity of the molded structure, or to allow welding to the additional layers, such as forming a barrier layer film, by heat sealing. Suitable thermoplastic fibers are polyolefin fibers such as polypropylene and polyethylene fibers. thermoplastic fibers may constitute a two-component or multicomponent fiber having a first component with a first melting point and two or more additional components with the pace of what torami melting different from the melting temperature of the first component. Bicomponent fibers typically have a configuration in the form of a fiber core of the first component and the shell of the second component or the configuration with the location of the components side by side. Suitable bicomponent fibers include bicomponent structure of the complex of polyester/polyethylene, polypropylene/polyethylene.

An example of a structure of composite material is layered non-woven material containing a first layer of thermoplastic fibers, a second layer of a mixture of thermoplastic fibers and absorbent fibers and the third layer, identical to the first. Then three layers connected by the supply thereto of heat at a temperature sufficient to cause melting of thermoplastic material, for example, using heated calender or by injection of hot air.

For bonding the individual layers of the present invention, namely, the covering element 30, the back sheet 13 and the absorbent material 31 (if the absorbent material is provided in the form of a separate layer) can be used any known connection methods, designed for the bonding of adjacent layers to each other. Representative, non-limiting list of methods and materials for connection includes all the I adhesives, the sealing, ultrasonic welding, solvent welding and mechanical fastening. It is preferable for the formation of a multilayer material of the individual elements attach them to each other are used structural adhesives. Suitable structural adhesives are described in the following U.S. patents No No 4526577, 5149741 and 5057571. Structural adhesives can be modified to give them the ability to absorption by incorporating absorbent polymer therein.

As shown in figure 5 and 6, the absorbent articles of the present invention can be individually wrapped with the formation of flat, folded or rolled item to ensure portability. In a preferred embodiment, at least one tape pull tab 20 is on the outside relative to the wrapper 50. This configuration allows the user to open an individually wrapped product 60 and separate the absorbent article 10 from the wrapper 50. Wrap 50 is possible, but not necessarily, may contain elements that make it suitable as a means for removing soiled products. Wrap 50 may be made of any materials known in the field as materials for such packaging purposes. In a preferred embodiment, the wrap is made of paper or poly the agreement of the film, such as polypropylene film.

Absorbent articles of the present invention can have any shape suitable for placement in the crotch of the user and its surrounding areas. Shapes include rectangular, oval shape with extended ends, the form of groundnuts and other Suitable shape may also be asymmetric shape, asymmetry refers to the transverse ends, and this form may be intended for use in underwear, made in the form of straps ("thong type" undergarments).

For use with absorbent articles of the present invention, the user first retrieves it from any external packaging, for example, from a flexible package or carton, as well as from any individual wrappers. Tape the tab will be in the folded position, so that the adhesive will be in contact with the zones of detachment, that is, the adhesive is still not open to influence. After this, the user must open to the influence of the adhesive on the tape the tongue, for example, by bending (folding) in a stretched position. The user can then glue the belt tongue to his underwear to save the location of the product before donning and in the process of pulling up underwear close to your body. Tape azco which provides additional advantages in the separation of the products from the underwear. The user can grab himself a tape pull-tab to remove product that is an alternative to grasping part of soiled articles. In addition, the soiled product can be folded or rolled and then maintained in this position by means of tape tabs for easy and discreet remove.

Descriptions of all of the patents, as well as any corresponding published foreign patent applications mentioned in this patent application, are hereby incorporated into it by reference.

Description and ways of implementation, introduced above, are intended to contribute to the full and non-limiting understanding of the invention disclosed in this application.
