Description

The present invention relates to absorbent articles. In the context of this description, the term "absorbent article" is intended to encompass any absorbent article that may be used in the field of personal care. The absorbent article of the present invention is especially intended to be a diaper-type article intended for use by infants, young children or adults to hold, contain and absorb liquid or solid secretions of the body, although other applications can easily be envisaged. or use cases of the product.

Published patent application WO 03/017902 discloses an absorbent article, such as a diaper, in which the front zone, the crotch zone and the rear zone can be secured to the carrier by means of waist elements and fastening elements. In particular, two waist elements, each of which protrudes laterally outward from the rear zone of the article, can be attached to each other around the waist of the wearer. The fastening elements provided on the inner surface of the front zone, in this case, provide the possibility of attaching the front zone to the belt in order to create a pant-like garment placed on the carrier. Another example of an absorbent article with a belt is described in US patent application 2002/0193776, wherein the article has a belt having a first and second part, each of which can be held on the inner surface of the article in a retracted position by means of detachable connection means.

Another absorbent article is described in WO 95/19753. In accordance with this document, a diaper-type garment is provided with waist elements protruding laterally from the rear panel of the garment, with each waist element having connection means at its distal end for attaching a corresponding waist element around the waist of the wearer or another waist element, or to the corresponding parts for connection provided on the outer surface of the front panel of the garment. Thus, a garment may be configured for use with either a worn (“sliding”) type configuration (sometimes referred to as a short panty type configuration) in which the distal end of each waist member is elongated partially around the waist of the wearer and attached to a corresponding portion of the front panel or with a belt-fastened configuration in which the respective ends are joined together around the waist of the carrier, the front panel being subsequently attached to the belt via tion of fastening elements on its side edges. However, as can be easily seen from document WO 95/19753, there is a difference in the size of the garment when it is worn in one or another configuration. In particular, due to the fact that the front panel forms a “jumper” between the respective ends of the belt, when the configuration of the garment is a configuration of the type to be worn, this configuration forms a larger circumferential size at the waist compared to the configuration with fastening by the belt formed for the same products. If one or another configuration is used, there will be a poor fit of the product, unless a stock of products of several sizes is provided for one user. In addition, the side edges of the front panel may not be sufficiently held in the configuration of the product, which is the configuration of the put on type, which can lead to instability of the side parts of the front panel and the resulting leakage, especially in the case of a movable carrier.

Diapers are also known in the art that can only be provided in the so-called don-on configuration, in which, as mentioned, the side panels of the article are attached to each other around the waist of the wearer. US Pat. No. 4,051,854 discloses a closure for an absorbent article, which may be provided either on a garment of the type being worn or on a garment fastened by a belt.

Another absorbent article is known from EP-A-1110529, wherein said article is described as containing a belt attached to the back panel of the article. The belt is held in storage by detachable means of connection and can be deployed for use by detaching the corresponding detachable means of connection. In use, the two free parts of the belt protruding from both sides of the rear panel can be connected together with the waist of the carrier, as well as with the front panel of the product on which fastening means are provided. Alternatively, the product can be worn in a don-on configuration by attaching the ends of the belt to the outer surface of the front panel. Since the belts must be fastened in both cases when they are fully extended, there is a difference in size between the belt fastened configuration and the worn type configuration, since the front panel creates a “jumper” effect.

EP-A-0528282 discloses a diaper-type article having belt portions protruding from each side of a rear panel. The product is intended to be worn in a configuration with belt fastening by connecting parts of the belt around the waist of the carrier and moving the front panel to a predetermined position using fastening elements on the side edges of the front panel, which are attached to the parts of the belt around the outside of the rear panel of the product. The front and rear panels are quite large in their lateral direction and overlap each other in a significant way when wearing the product. In some cases, the front panel may be attached to the rear panel without first attaching parts of the belt to each other. In this case, parts of the belt will be on the inside of the front panel, which causes discomfort and poor fit.

WO 01/21120 discloses an absorbent article that has a crotch portion between a front and a back panel. The rear part in its transverse lateral areas is provided with laterally protruding fastening flaps, which can be respectively attached to the lateral areas of the front panel to give the product a worn configuration to be worn. The valves are formed as part of a continuous belt, which is attached to the inner surface of the rear panel and which contains folds to enable some increase in the length of the belt within the rear panel by overcoming elastic displacement. The described garment can only be worn in the configuration of the type worn.

This design feature in the art, according to which absorbent articles can be worn either in a belt-fastened configuration or in a worn type configuration, has been developed to adapt to various requirements and preferences of end users. However, in each of the known products of this type, there is a difference in size between the two product configurations. Such a difference in size, apparently, can be compensated by using elastic elements, although in such a case the product will tend to fit more tightly in the configuration with fastening by a belt, which causes discomfort for the carrier.

Many users of absorbent articles may have limited physical strength and limited dexterity (dexterity). Giving a specific configuration to similar products and donning similar products can be problematic in terms of the required efforts required to give a specific configuration to the product, and also the directions in which the corresponding forces should be applied. In addition, it is necessary to take into account the movement of the limbs of the wearer or user during the application of force (for example, to open or close the garment) when designing absorbent products, since certain actions of the limbs are more difficult to perform than others when the force is applied.

There is a need for an absorbent article of the aforementioned type, which can be configured in a flexible manner that does not cause discomfort, and whose dimensions are essentially the same regardless of the configuration that was attached to the article. In addition, there is a need to provide additional constructive flexibility of absorbent products while maintaining material costs at a minimum. In addition, there is a need for an absorbent article that makes it easier for users to give them a specific configuration for use. Product users include product carriers, as well as carers for those who wear absorbent products.

In addition, there is a need to keep the use of materials in such products to a minimum for cost reasons and to reduce the volume of the products on the carrier. In addition, there may be an advantage due to a decrease in the surface area of the wearer's body that is coated with the article, since prolonged contact between such articles and the skin of the wearer may in some cases cause irritation and discomfort. When developing such products, care must be taken to ensure that the design of the product takes into account the requirements of comfort and good fit to the carrier.

The present invention is directed to an improved absorbent article. In particular, in accordance with the present invention, an improved absorbent article is provided that takes into account the various aspects mentioned above.

In this regard, in accordance with the present invention, an absorbent article having a top sheet, a back sheet and an absorbent core between them is developed; wherein said absorbent article comprises a main panel having a longitudinal axis extending in the longitudinal direction and a transverse axis extending in the lateral direction, wherein said main panel further comprises a crotch region between the front panel and the rear panel, wherein the crotch zone and the front and rear panels have each inner surface and outer surface; wherein the absorbent article includes a belt having a first belt part and a second belt part; moreover, each of the first and second parts of the belt has a distal section extending laterally from the corresponding connection zone, while in the connection zone the specified part of the belt is attached to the rear panel; wherein, near the distal end of at least one of the waist elements, a fastening belt element is provided which is adapted to attach said first and second waist elements to each other around the waist of the carrier; moreover, in conjunction with each respective first and second part of the belt, a detachable connecting means is provided, which, when in a connected state, ensures fixation of these parts of the belt in the allotted configuration, and in the specified allotted configuration, the distal zone of each specified part of the belt is held with the possibility of detaching directly or indirectly ( indirectly) at the outer surface of the rear panel, and at the same time, when the detachable connection means are disconnected, an elongated (elongation n) the configuration of the corresponding indicated part of the belt, and in the elongated configuration, these parts of the belt can be connected to each other by means of a fastening element of the belt.

In other words, the absorbent article is provided with closing means for securing the article around the waist of the wearer. The product can be worn in a belt-fastened configuration or in a worn type configuration. Belt means are provided that are held in a retracted position along the back of the product. The detachable connection means allow to extend the belt partially or completely. The fastening elements on the front panel may be attached to the respective waist means in a don-on configuration in which the waist means are in a partially or fully allotted configuration. A belt-fastened configuration can be formed with a fully extended configuration (with full extension) of the corresponding parts of the belt, in which the ends of the belt can be attached to each other around the waist of the wearer. The product may have a substantially constant or uniform size both in the configuration of the worn type and in the configuration with belt fastening.

The term "belt" in this case should be understood as meaning "belt means", and it is intended to describe a longitudinal, essentially flat element that can be fastened around the waist of the carrier by means of one or more fastening elements. Although the invention has been defined with respect to a belt having two parts of a belt, it is obvious that although it is possible to make two parts of a belt, each of which protrudes from a corresponding opposite side zone of the waist panel, additional belts or parts of the belt may be provided in accordance with the invention optionally for comfort and a secure fit. In addition, the belt can be made in the form of one continuous belt with the first and second parts protruding laterally from the rear panel of the absorbent product, or in the form of separate parts of the belt, while the first and second parts of the belt can be attached to the opposite side of the back panel so that it will protrude laterally from it. The corresponding parts of the belt can be attached to the rear panel using any suitable means. The term “connection zone” should be understood to mean that part of the absorbent product that provides the connection of the rear panel with the belt.

Each part of the belt has a distal section, which protrudes laterally from the connecting part and, therefore, forms the free end of the corresponding part of the belt. The distal portion forms a portion of the corresponding part of the girdle, starting from the connection zone and ending at the distal end. The distal end covers the end edge of the distal portion of the belt part, as well as the distal end zone of the specified part of the belt, while the distal end zone is inside with respect to the distal end or the distal end edge and has a size from the specified distal end edge, located, for example, in the range from the width of the finger to the five times the width of the finger. The connection zone between the parts of the belt and the rear panel may be provided on the inner or outer surface of the rear panel. In the case where the connection zone of a part of the belt is provided on the inner surface of the rear panel, the belt can cover laterally in the transverse direction the edge of the panel to the outside, where it can be held in its retracted position. The belt covering the lateral edge of the rear panel can be made in such a way that the portion of the belt which covers the lateral edge does not protrude beyond the lateral edge of the rear panel. In this regard, any value by which the covering part may protrude beyond the lateral lateral edge will not constitute a “useful” value.

Each panel of the absorbent article has an inner and outer surface, the inner surface being a surface facing the body. Similarly, the belt or parts of the belt have an inner or inner surface that, when the belt is stretched, faces the wearer's body. The outer or outer surface of the belts or parts of the belt or the main panel or its parts is a surface facing away from the media.

The user can selectively give the absorbent article of the invention either a worn type configuration or a belt fastened configuration. In both cases, the front panel can be attached to parts of the belt. To create the configuration of the put on type, the front panel can be connected to the parts of the belt in their allotted configuration, in which they are held directly or indirectly on the outer side of the rear panel by means of detachable connection means, while in this configuration the parts of the belt do not protrude laterally or do not protrude in the lateral direction to any significant or substantial degree beyond the lateral edges of the rear panel. In a belt-fastened configuration, the front panel can be attached to parts of the belt, which themselves are in an elongated (elongated) configuration after the first detachable connecting means are disconnected and connected together around the waist of the carrier. The absorbent article of the invention allows flexible configuration of the article for use and, in particular, provides similar flexibility while maintaining comfort and good fit for the wearer. The implementation of detachable means of connection connected to the outer side of the rear panel, allows you to hold parts of the belt, at least partially, on the outer surface of the product. Thus, some knocking of the belt parts into “lumps” on the inside of the product, which would occur when the user wears the product in the configuration of the type being worn, could be prevented if the belt parts, for example, were to be kept loose on the inner surface of the rear panel . Furthermore, since the fastening elements of the belt are often more rigid than the material of the belt, there would be a possibility of discomfort caused by similar fastening elements present on the inner surface of the absorbent article.

In a further embodiment, one or more panel fastening elements may be provided for fastening the front panel to the belt around the waist of the carrier or when the detachable connection means are connected or when the detachable connection means are disconnected. The configurations created as a result of this, respectively, can correspond to the configuration of the worn type or configuration with fastening through the belt.

With the allotted configuration of the belt portion, the distal end zone of the belt is detachably connected directly or indirectly to the outside of the rear panel by means of detachable connection means. This connection of the distal end zone of the belt with the rear panel includes embodiments in which the distal end zone of the belt is attached to a layer of thin material located on a portion of the rear panel, wherein said layer of thin material serves as a retainer for part (s) of the belt. The retracted belt shape may be a suitable configuration for packaging and transportation, as well as for using the product in a don-on configuration in some embodiments. Although it is envisaged that the distal portions of the belt portions will be held directly or indirectly at the outer surface of the rear panel with the retracted positions of the belt portions in accordance with all embodiments of the invention, however, a connection area between any part of the belt and the rear panel can be located or on the inside or outside of the rear panel, and wherein the distal portion is located or folded as needed.

The releasable coupling means may be applied to the inner or outer surface of the belt portion. Thus, in the folded state, the distal end zones of the respective parts of the belt can be attached to the outer surface of the rear panel. Alternatively, a detachable connection means for holding the belt in a folded configuration may be provided on the inner or outer surface of the belt part.

The detachable connection means, in particular, can be provided in the form of one or more detachable connections between the outer surface of the rear panel and the section of each of the parts of the belt, which are parallel to the outer side of the rear panel and, possibly, on the outer side of the rear panel. Alternatively, detachable connecting means may be provided so that the first part of the belt will be detachably connected to the outer surface of the rear panel, while the second part of the belt will be located above the first part of the belt and will be detachably attached to the outer surface of the first parts of the belt. These joints can preferably be provided in the form of adhesives or welds, such as welds obtained by ultrasonic welding or heat sealing, although there are other possibilities. They can be made in the form of compounds in one place, or in the form of multiple compounds. Connections forming detachable connection means may be point connections. Any detachable connection means may preferably be destroyed upon disconnection. Alternatively, detachable connection means may be reconnected. They can be arranged in the form of a pattern, for example, in the form of a pattern of point connections. Suitable releasable coupling means may be provided in one or more places along the length of the corresponding portion of the belt. It is envisaged that in the aforementioned folded configuration of the belt part, the fold line will be oriented in a direction substantially parallel to the longitudinal axis of the absorbent article, for example, it will be between the first detachable connection means and the second detachable connection means when viewed in the longitudinal direction of each part of the belt.

Other suitable materials may be used for releasable means (s) of connection on a part of the belt. Such material may include glue applied to one or both surfaces of the belt portion to be fixed. Alternatively, the connecting means may comprise adhesive tape applied to one or both surfaces, or mechanical fastening means attached to one or both surfaces. For example, the connecting means may consist of a fastening element such as hooks and loops, or it may consist of a mechanical fastening means attached to only one surface, which can be attached to a part of the belt made of non-woven material. In addition, it can be any combination of the means of connection mentioned above.

The force required to separate or disconnect the detachable connection means may preferably be of a magnitude not exceeding that which can be easily applied by the fingers of the user. However, with the retracted or folded configuration of the part of the belt in which the means of connection is in a connected state, that is, in an untouched state, the corresponding means of connection must be sufficiently elastic so that they can withstand the tensile forces exerted by the user when donning the item clothing, and any forces acting during normal use, due to the fact that they are under some tension around the waist of the wearer.

In a further embodiment of the invention, detachable connection means for each part of the belt may be provided as first detachable connection means and second detachable connection means. In such a case, each second detachable connection means can hold the corresponding parts of the belt in an additionally folded configuration, in which the distal end zone of each part of the belt is fixed so that it can be detached from another part of the same part of the belt. Thus, when the first and second detachable connection means are disconnected, a second elongated (elongated) configuration of the respective indicated parts of the belt is formed. This means that the corresponding parts of the belt can be increased in length to a first increased length when the first detachable connection means are disconnected and to a second, even larger length by disconnecting the second detachable connection means.

In the case where the belt parts are provided with the first and second detachable connection means, the belt parts can be used to create the configuration of the garment, representing the configuration of the worn type, by disconnecting the first detachable connection means and without disconnecting the second detachable connection means in the distal end zones relevant parts of the belt. A similar configuration of the put on type can be formed by introducing fastening elements located, for example, on the front panel of the absorbent article, which can be located in its respective opposite side zones, meshing with each of the first and second waist means in their first elongated configuration. Ensuring the presence of belt means in a folded configuration can provide the ability to hold a belt of greater length, for example, on the rear panel, which is relatively narrow.

The configuration of the product, which is a configuration with fastening by a belt, can be formed by disconnecting both the first and second detachable means of connection to obtain an additional elongated configuration and by subsequently connecting the corresponding parts of the belt using a fastening element of the belt around the waist of the carrier, while completing the front panel is attached to the belt formed in this way.

The corresponding waist sizes thus obtained can be substantially the same both in the configuration of the type to be worn and in the configuration with belt fastening.

In particular, in order to obtain substantially the same waist sizes, as mentioned, the corresponding belt lengths and elongation values can be appropriately selected. In one embodiment, each part of the belt can be increased in length by disconnecting the first detachable connecting means by a length substantially equivalent to at least half the distance that separates the two fastening elements of the panel located in the laterally opposite areas of the front panel, or by a length substantially equivalent to at least half the distance that separates the laterally opposite edges of the front panel. In an additional embodiment, the parts of the belt containing the second detachable means of connection can be increased in length, when the second means of connection are disconnected, by a total amount substantially equivalent to at least the distance that separates the two fastening elements of the panel, located in opposite the lateral direction of the zones of the front panel, or by an aggregate value substantially equivalent to at least the distance that separates the two opposite laterally opposite edges in front of her panel.

An elongated (elongated) or additional elongated configuration of a part of a belt means a configuration in which the detachable connecting means of the waist element is disconnected so that the waist element has a length that exceeds the length of the waist element in its folded configuration, i.e. when the connecting means is in the connected state. An elongated or additional elongated configuration, which can be obtained by increasing the length of the product by means of the first and / or second detachable connecting means in accordance with aspects of the invention, should be distinguished from any increase in the length of the belt part by means of tensile or elastic materials used in whole or in part for the belt or for any of the front or back panels. Such elastic or extensible materials may be further used in embodiments of the present invention.

The described invention allows the user, when giving the product some configuration for use, to easily increase the effective length of one or more of the parts of the belt before attaching the parts of the belt for use either to each other or to the front panel. The effective length of the part of the belt referred to here is intended to indicate the length of the part of the belt measured between its extreme points, in other words, the length from the connecting part provided on the part of the belt to the end created by the bend - when the part of the belt is in folded configuration, or distal end edge - in the case when the belt is in an elongated (elongated) configuration. It is important that the ability to increase the effective length of the belt, which is thereby ensured, allows the user to maintain a constant size in the circumferential direction at the waist in a fixed state, regardless of which configuration is chosen - the configuration of the worn type or the configuration with fastening by the belt. Therefore, it is no longer necessary to store products of several sizes simply to enable the use of various fixing methods. In addition, the invention makes it possible to regulate the length independently of any tensile effects caused by elastic elements that may be provided in parts of the belt or in parts of the respective panels.

Preferably, the length of the part of the belt in its folded configuration, measured between the connection zone and the extreme point of the part of the belt in which the fold line is located, if the belt is bent (i.e., part of the length along the actual length of the corresponding part of the belt in an extended state) can be in the range from one sixth of the distance between the opposite side edges of the front panel to the full distance between the specified side opposite edges of the front panel (measured when the panel is not tensioned and broken wife exactly on the plane). Alternatively, the corresponding length may preferably be in the range from one quarter to three quarters of the distance between the opposite side edges of the front panel. As another further alternative, the corresponding length may preferably be in the range of one third to two thirds of the distance between the opposite side edges of the front panel. As yet a further alternative, the corresponding length may preferably be in the range of one quarter to half the distance between the opposite side edges of the front panel. As yet a further alternative, the corresponding length may preferably be between half the distance between the opposite side edges of the front panel and one and a half times the distance between the opposite side edges of the front panel. As a further additional alternative, the corresponding length may preferably be between three quarters of the distance between the opposite side edges of the front panel and 1.25 times the distance between the opposite side edges of the front panel.

The folded part of the belt, having the length discussed in the above paragraph, can be extended to an additional elongated (elongated) configuration by disconnecting the second detachable connection means holding the folded end of the part of the belt, which leads to an increase in the actual (effective) length of the part of the belt by an amount equal to or greater than a quarter of the distance between the opposite side edges of the front panel, or by an amount equal to or greater than a quarter of the distance between the two fastening elements s located at the laterally opposite parts of the front panel. Alternatively, the length of the part of the belt in its folded configuration can thereby be increased by an amount equal to or greater than one third of the distance between the opposite side edges of the front panel, or by an amount equal to or greater than one third of the distance between the two fastening elements located in the opposite side direction of the front panel zones. As additional options, the length of the belt part in its folded configuration can thereby be increased by an amount equal to or greater than half or two thirds of the distance between the opposite side edges of the front panel or the entire distance between the opposite side edges of the front panel, or by an amount equal to or exceeding, respectively, half or two-thirds of the distance between two fastening elements located in the laterally opposite areas of the front panel, or ce distance between the two fastening elements disposed in the laterally opposite parts of the front panel. In some embodiments, it may be preferable to provide for such a length of the folded portion of the belt in its elongated state that is approximately equal to or greater than the distance between opposite side edges of the front panel (or between two fastening elements located in laterally opposite areas of the front panel), in this case, it can exceed the indicated distance by a maximum of one and a half times. This provides an important ability to compensate for differences in size due to different product configurations. In addition, ensuring the presence of a waist means, the length of which can be increased, creates the possibility of a better fit for individual carriers, since the waist sizes of the carriers can vary significantly, and the waist circumference of an individual carrier can also change with time.

As you can understand, the provision, in certain embodiments, of the retracted and / or folded parts of the belt on both sides of the rear panel can create a possibility for the front and rear panels to be reduced in width, since the front panel can be secured by fastening means on the front panel fixed in some place on a part of the belt. Therefore, the respective panels need not be dimensioned sufficient to ensure that they are in contact with each other when worn around the waist of the wearer. In addition, tensile sections of the front panel and tensile fastening elements of the panel provide an additional opportunity to reduce the size of the front and rear panels in width.

The term “panel fastener” can be interpreted to mean a hook type fastener in combination with a piece of adhesive tape or film or laminate. To obtain a substantially constant waist size in the two aforementioned configurations or to provide increased comfort for the user, such a fastening tab can be extensible. The portion of the panel itself to which the panel fastening element is attached may include one or more stretchable portions. Thus, in some embodiments, it may be desirable to provide some extensibility of the front panel by making tensile portions of the material either as part of the fastening elements of the panel on each side of the front panel, or as part of the edges of the front panel itself, laterally in the transverse direction. On the other hand, the fastening elements of the panel may essentially not stretch under the influence of loads that may be applied by the user or the carrier during use.

The degree of extensibility of the fastening element of the panel or the side edge zone of the front panel may vary depending on the type of belt that is provided, and depending on the dimensions of the front and rear panels. The combined extensibility of the fastening elements of the panel and / or the side edge zones of the front panel on either of the two sides of the front panel can be such that the total transverse dimension of the front panel, measured from its one edge zone to its other edge zone, can be increased by at least at least one third of the size of the front panel, measured in an unstressed state. More preferably, the front panel can be extensible to such an extent that the transverse size of the front panel can be increased by at least half or at least two-thirds of the size of the front panel in an unstressed state. It should be understood that in most embodiments, at least two fastening elements of the panel are provided on the front panel, with each side edge region of the front panel being provided with at least one similar fastening element.

As mentioned above, it is envisaged to use tensile material, in particular in the front panel, to enable easy configuration of the wearable type with the allotted configuration of the belt parts. In addition, it may be desirable to provide for the presence of tensile material in the front panel to provide comfort for the wearer. The amount of stretchable material and the stretchability of the material will vary depending on the need to ensure the possibility of significant increase in size or on the need to simply ensure a good, comfortable fit.

Additionally or alternatively, extensible material may be provided in at least one front or rear panel, for example, in their central zone, thereby thereby providing lateral extensibility of the respective said panel. Preferably, the front panel can be extensible to such an extent that the transverse size of the front panel can be increased by at least one quarter or at least one third of the size of the front panel in an unstressed state. More preferably, the front panel can be extensible to such an extent that the transverse size of the front panel can be increased by at least half or at least two-thirds of the size of the front panel in an unstressed state.

In some cases, it may be desirable for the fastening elements of the panel to be substantially inextensible, in particular in cases where sufficient extensibility is provided on one or both of the front and rear panels.

Tensile stretches (sections) of materials provided to enable a substantial increase in the size of the front panel, including its lateral edge zones, should preferably be tensile up to 10% elongation under the action of a force of 45 to 250 g per 25 mm, measured by ASTM D-882 Test Method (ASTM - American Society for Testing Materials). Preferably, the required force is in the range from 55 to 210 g per 25 mm, in addition, preferably from 65 to 180 g per 25 mm, in addition, preferably from 75 to 150 g per 25 mm, in addition, preferably from 80 to 120 g per 25 mm, in addition, preferably from 84 to 105 g per 25 mm, in addition, preferably from 88 to 98 g per 25 mm. Alternative possible ranges include values from 85 to 150 g per 25 mm or from 65 to 100 g per 25 mm.

Preferably, if the material used can "exert" force (exert force) at 100% elongation, measured by ASTM D-882 test method, ranging from 200 to 550 g per 25 mm. Preferably, the specified force required for 100% elongation is in the range from 230 to 470 g per 25 mm, in addition, preferably from 250 to 400 g per 25 mm, in addition, preferably from 260 to 450 g per 25 mm, in addition, preferably from 270 to 400 g per 25 mm, in addition, preferably from 280 to 350 g per 25 mm, in addition, preferably from 290 to 330 g per 25 mm or from 300 to 340 g per 25 mm. Alternative possible ranges include values from 280 to 550 g per 25 mm or from 200 to 360 g per 25 mm. The same materials can be used to provide elasticity in parts of the belt, in which the same tensile forces can be provided.

The fastening elements, made in the form of fastening elements of the panel, can be attached to the front panel for fastening the front panel or to a belt connected around the waist of the carrier, or to the corresponding first and second parts (or to a larger number of parts) of the belt, partially elongated around the carrier. To this end, fastening elements may be provided on the front panel in different places on the panel as may be necessary. In particular, the fastening elements are arranged such that at least one fastening element is located on the front panel at each opposite side zone or next to each opposite side zone of the said panel, preferably on the inner surface of the front panel. In some cases, it may be desirable to place fastening elements on the outer surface of the front panel. Thus, the front panel, including its side edges, is secured to parts of the belt regardless of the configuration chosen by the carrier or user. Alternatively, the fastening element may be in the form of a strip extending essentially across the entire front panel.

The fastening elements may be detachable and may contain any suitable alternatives known in the art. For example, segments of adhesive tape or tabs of adhesive tape, possibly covered by a removable layer, as well as mechanical fastening means, such as tape fastening elements in the form of hooks and loops or fastening elements such as hooks, which can be bonded with fibers of a belt material such as like non-woven fabric. In addition, the fastening elements of the panel can be made in the form of means such as hooks, interacting with sections of material in the form of loops provided on parts of the belt.

It should be noted that the product described above is intended to be “reversible”. That is, it means that the product can be placed on the carrier so that the back panel, from which the parts of the belt protrude outward, will be placed at the front of the body of the specified carrier, while the waist elements in this case will extend backward or completely, or partially around the waist of the wearer, either in a folded or elongated (elongated) configuration, for closing the product or in a configuration with fastening by a belt, or in a configuration of a worn type. Typically, users may prefer to give the product a don-on configuration with a front panel located at the rear of the body and a rear panel located at the front of the body, with parts of the belt extending back around the waist of the wearer. Thus, the forces that must be applied when attaching the side parts of the front panel to the parts of the belt can be applied by the hands of the carrier, grabbing the side edge area of the front panel and pulling it forward to place it on top of the corresponding part of the belt and thereby securing it to location. The user placing the product in a belt-fastened configuration may prefer to place the back panel at the rear of the body by disconnecting the means for connecting the belt part and pulling the free ends of the respective belts (belt parts) forwardly around the waist before connecting them together around the front of the body by fastening element. In addition, in this case, the forces that need to be applied when pulling parts of the belt around the waist of the wearer can be applied by pushing the arms forward.

A general illustration of a possible product design in accordance with the invention is shown in FIG. It is shown that the illustrated absorbent article has a main panel 10 (or base panel), which is formed essentially from the crotch zone 6 located between the front and rear panels, respectively 4 and 5. The product has an outer impermeable layer in the form of a back sheet 2 illustrated on the outer surface of the product. The top sheet 1 is provided on the inner upper surface of the product. An absorbent core 3 is located between the top sheet 1 and the back sheet 2. Many other layers can be provided. Each layer can be unitary (single) or composite (composite). For example, the absorbent core 3 can be formed predominantly from one material or from a combination of materials made as laminates or distributed in the respective zones of the absorbent core. Many different types of absorbent materials, back sheets 2 and top sheets 1, as well as other layers, are known in the art for use in absorbent articles. The terms "front panel" and "rear panel" are used to define parts of the product relative to each other, and these panels when used can be freely placed on the media in a position in which the front panel will be located at the rear of the media body, while how the back panel will be placed at the front of the media body. To this end, the absorbent core 3 in some embodiments may be symmetrical about the transverse center line (not shown) of the article. The crotch portion 6 and the corresponding panels 4, 5 may be integral or may be formed from separate elements. The longitudinal axis LO extending in the longitudinal direction of the article and the transverse axis LA extending in the lateral direction of the article are shown for reference purposes. As can be easily seen, on the illustrated product, essentially an inner surface is formed that is designed to abut against the body of the carrier, and an outer surface designed to be facing outward from the body when the product is in a predetermined position on the carrier .

The belt consists of two parts of the belt, namely the first part 8 of the belt and the second part 16 of the belt, although both parts of the belt can be formed from one element. Parts 8 and 16 of the belt are shown attached to the rear panel 5 in the connecting parts 19, 20. They can be made of any suitable material, such as a film type material or fibrous material. An example of a fibrous material may be a nonwoven fibrous material formed from polyethylene or polypropylene fibers. Some other suitable belt materials of the present invention, as well as a method for their manufacture, are disclosed, for example, in WO 03/017904. Composite materials and combinations of belt materials, such as laminate materials, may also be provided. Many different non-woven materials can be used for use in parts of the belt. Examples of materials include a composite material formed from a laminate of a carrier material that forms the outer side of the belt and a soft nonwoven material that forms the inner side of the belt intended to fit directly to the skin of the carrier. Suitable non-woven material may consist of spunbond material, for example polypropylene or polyethylene fibers. Bicomponent fibers may also be used. Another suitable non-woven material consists of carded thermally bonded material, for example polypropylene, polyester or bicomponent fibers. As the carrier material, a plastic film or other suitable material can be used, for example, the aforementioned nonwoven materials. The carrier material may be adapted to function as a receiving surface for the front panel fastening devices 25, 26 of FIG. In the case when these devices consist of adhesive (sticky) tapes, a plastic film may be suitable, which can interact with the corresponding “parking” zone (not shown) on each of the belt parts 8, 16. In the case where other types of fastening devices are used instead of adhesive tapes, for example, materials in the form of hooks and loops, another type of carrier material is needed that can function as a receiving surface for the fastening device in question. An important detail is that the belt parts 8, 16 are preferably breathable so as not to clog the skin of the wearer wearing them. To ensure a comfortable fit, the width of the belt parts 8, 16 can be from 5 to 20 cm, preferably from 7 to 15 cm.

The connecting parts 19, 20 are located at the laterally opposite side zones of the rear panel, inside with respect to the corresponding laterally opposite side edges 34, 35 of the rear panel 5. In Fig. 1, the connecting parts 19, 20 are shown extending from the closest to the center points of one end of the first and second parts 8, 16 of the belt outward towards the respective opposite side edges 34, 35. The connection between the parts 8, 16 of the belt and the rear panel 5 can be carried out by any suitable means 21 (Fig. 8), such as an adhesive, or means in the form of a weld or thermally bonded joint. In some embodiments (not illustrated), the belt parts 8, 16 may be made of the same material as the material of the back panel 5, in such cases, there may be no side edges of the rear panel 5 as such. The corresponding opposed to each other, the side edge zones of the front panel 4 are indicated by the numbers 17 and 18.

In Fig. 1, parts 8, 16 are shown in an allotted elongated state suitable for storage and transportation and suitable for shaping an absorbent article, which is a don-type configuration illustrated by the general example of Fig. 3. A similar configuration can be formed by pulling the side zones 17, 18, including the fastening elements 25, 26 of the panels around the waist of the carrier and attaching the fastening elements 25, 26 to the corresponding part 8, 16 of the belt.

In figure 1, each of the parts 8 and 16 of the belt is held in a retracted configuration at the outer surface of the rear panel 5 by means of detachable means 27 of the connection. In the case illustrated in FIG. 1, two point joints or welds or glue spots are used as releasable bonding means. In some embodiments, such releasable bonding means 27 may comprise one or more point joints or welds or glue spots.

On figa illustrates an option in accordance with which the first and second parts 8, 16 of the belt are provided with detachable connection means 27 in the form of connections for connecting the two parts 8, 16 together with the possibility of separation in the designated configuration, in which they overlap at the outside surface of the back panel. In addition, the first part 8 of the belt, if required, can be detached to the outer surface of the rear panel 5.

The belt fastening element 23 is shown generally in FIGS. 1 and 1a. The fastening element 23 of the belt can be placed on the inner or outer surface of the belt part 8, 16.

The carrier may configure the product to be secured with a belt for use by disconnecting the detachable connecting means 27 and attaching the belt fastening element 23 provided, as shown by way of example, in the distal end zone of the second belt part 16 to the first belt part 8. The first part 8 of the belt may, in turn, be provided with one or more zones of attachment ("parking") for the fastening element 23 of the belt. Alternatively, the fastening element may be adapted to be attached anywhere along the length of the first belt portion 8. In one embodiment, the fastener 23 may comprise a mechanical fastener, such as a tongue with spikes or a tongue with hooks, while the belt portions 8, 16 can be made of fibrous material with which the mechanical fastener can be engaged. Alternatively, the fastening member 23 may be an adhesive member that may be covered by a removable tape. Such an adhesive element can be adapted to be attached anywhere along the length of the belt part 8, 16, and it can interact with the attachment (“parking”) zones provided in one or more places along the belt part 8 or 16. Another possible fastening element may include a tongue provided with a connecting part with hooks, as well as having a tensile or elastic part. An example of a belt fastening configuration according to one embodiment of the present invention is shown in FIG.

The elongation of the product can be achieved by making the fastening elements 25, 26 of the panel in the form of elastic tongues with hooks (not shown) or by making the elastic part 32 in the front panel 4. Alternatively (not shown), the belt parts 8 and 16 can be made or fully or partially from extensible material.

Figure 2 shows an additional embodiment of the present invention, in which substantial elongation of the product can be achieved by incorporating elastic materials in the corresponding lateral edge zones 17 and 18, as well as, possibly, the elastic part 32 in the central area of the front panel 4. Parts 8, 16 the belts are provided in a folded designated configuration, from which they can be extended to the first and additional elongated configuration. To this end, detachable connection means 27 may be provided on each belt part 8, 16 in the form of a first detachable connection means 28 and a second detachable connection means 29. Thus, the illustrated product has a greater degree of flexibility in terms of the ways in which it can be put into a “working” state for use. On the one hand, the extensibility of sections 32 and 17 and 18 of elastic material can allow the product to be stretched to the required dimensions to ensure fastening of the fastening elements 25, 26 around the user's waist, directly to the allotted parts 8, 16 of the belt when the first and second releasable connection means 28, 29. A similar configuration is shown in FIG. 3 and corresponds to the configuration of the put on type. Alternatively, the belt portions 8, 16 can be deployed by disengaging only the corresponding first detachable connecting means 28, thereby forming a wearable type configuration on the carrier (see, for example, FIG. 6), which requires a lower degree of extensibility of the front panel and side edge zones than that required for the configuration shown in FIG. 3. Figure 5 shows an example embodiment of the invention in which the extensibility of the front panel is provided by means of an elastic or creped part in the central area of only the front panel 4. Additional extensibility can be achieved by combining the extensible central part with tensile portions in other parts of the front panel 4 or parts 8 , 16 belts. Alternatively, additional extensible parts may be provided, such as those illustrated in FIG. 2, or a continuous extensible part extending substantially over the entire width of the front panel, as illustrated in FIG. 7.

In Fig. 7, a material that is capable of being plastically deformed to some extent at low levels of force can be used in the back sheet layer to accommodate a substantial elongation of the stretch portion 32 of the front panel, which extends substantially over the entire width of the panel.

In yet a further alternative embodiment, the product may be configured with a belt fastening by disengaging both the first and second detachable connection means 28, 29 to completely extend a portion of the belt to an additional elongated configuration, thereby allowing the belt to be secured around the waist of the carrier by fastening element 23, as shown in Fig.4.

As can be seen from the various illustrated embodiments, an absorbent article in accordance with the invention may be provided, in particular, with two belt parts 8, 16. Parts 8, 16 of the belt, in the form in which they are illustrated, can be used to give the absorbent product a configuration that is a configuration of the worn type and designed to be worn in a position in which the front panel 4 can be placed on the rear side of the waist of the carrier, with this fastening elements 25, 26, provided as an example in the lateral edge zones 17, 18 of the panel and on its inner surface, are moved forward around the carrier and attached to the corresponding part 8, 16 of the belt. One or more fastening elements 25 and 26 may be additionally or alternatively provided on the outer surface of the panel 4 (not shown). Alternatively, fastening elements 25, 26 can be provided on the lateral edges of the front panel in the form of adhesive fastening tabs that can be separated from the removable layer on the front panel and attached to the corresponding part on the belt. The belt parts 8, 16 can be made of a material to which the fastening element 25, 26 can be easily attached. To this end, one or more fastening elements may be formed of an adhesive strip or mechanical fastening means, such as a fastening element with hooks, able to reliably adhere to any fibrous material of the belt parts 8, 16. For certain types of fastener elements, appropriate attachment locations (“parking lots”) (not shown) may be provided on belt parts 8, 16 for receiving adhesive or mechanical fastener elements 25, 26. In other embodiments, additional fastener elements 25, 26 may be provided (not shown), or fastening elements may be provided in the form of a single fastening element (not shown) covering most of the width of the front panel.

The releasable coupling means 27 or 28 or 29 in accordance with various embodiments may extend along the length of the belt portion 8. Therefore, the length of the connection means 27, 28, 29 is greater than the local one, although the connection means can be disconnected in the same way as the connection means 27 illustrated in FIG. 1, namely by applying force with the fingers of a user so as to separate two layers. In particular, this can be done by grasping the free distal end of the belt portion 8 near the distal edge and pulling it in such a direction as to separate the layers. The releasable joint means 27, 28, 29 may be provided in the form of a weld or glue line, although there are other possibilities for creating the joint means 27, as already discussed. Examples of detachable connection means are further shown in FIGS. 8 and 8a-8c. As you can see, to ensure ease of separation, the detachable connection means 27 can be made in the form of separate connecting points in staggered places along the folded part of the belt. Each of the staggered places may contain lines of separate connecting points, or they may consist of a zigzag contour of connecting points. The joints may be any suitable type of joint and may include glue stains or spot welds.

In some embodiments, detachable connection means may be provided on the rear panel 5 in the form of holding means 39 made of a piece of thin material (Fig. 8c) located below or above at least the distal end zones of the respective belt portions 8, 16 with in order to thereby ensure that they are held in place at the rear panel 5. The layer of thin material for the holding means 39 can be made of any suitable material, in particular, it can be a fibrous layer of sludge and a layer of nonwoven material. In some cases, the thin material layer can only be attached to the rear panel 5, with the ends of the belt being located under the holding means 39. The holding means 39 or the thin material layer can be attached (fixed) to the rear panel 5 by spot welds or spots 40 glue. The holding means 39 can also be attached directly to each distal end zone of the belt. The belt can be deployed by breaking the holding means 39 and releasing the corresponding parts 8, 16 of the belt. To this end, weakening lines 37 may be provided in the thin material layer 39, which are intended to enable the belt parts 8, 16 to be released from their configuration in which they are held (from the folded configuration). The second detachable coupling means 28 may be provided in addition to the holding means 39 in those cases where a first and second degree of elongation of the belt is desired, or when a greater possibility of extending the belt is required than that which can be achieved with one detachable coupling means.

Therefore, due to various possibilities of increasing the length of the belt parts 8, 16 and the front and rear panels 4, 5, the length of the product in the circumferential direction around the waist of the carrier in the configuration with fastening by the belt can be essentially equal to the length of the product in the circumferential direction around the waist of the carrier in donned configurations.

Some extensibility of the parts of the belt or their sections, or the extensibility of the front panel 4 can be achieved by the inclusion of elastic means or by the formation of folds. Combinations of folded or creped parts (not shown) and elastic parts 32 may also be used.

A wide range of materials can be used to provide extensibility. Such elastic materials may contain an elastomeric material that has elastomeric properties under environmental conditions, that is, the material will basically restore its original shape after being stretched. Preferably, the elastic material will have only a small residual deformation after deformation and relaxation, wherein said residual deformation is less than 30% and more preferably less than 20% of the initial tensile from 50 to 500%. The elastomeric material may contain either one or more pure elastomers or mixtures with an elastomeric phase or elastomer content, which will still have significant elastomeric properties at room temperature. Suitable elastomeric thermoplastic polymers include block copolymers or the like. These block copolymers are described, for example, in US Pat. Nos. 3265765, 3562356, 3700633, 4116917 and 4156673. In particular, block copolymers of styrene and isoprene, styrene and butadiene or styrene and ethylene butylene are suitable. These blocks can be arranged in any order, including linear, radial, branched or star-shaped block copolymers. Other suitable elastomeric polymers may include elastomeric polyurethanes, elastomeric copolymers of ethylene, such as ethylene vinyl acetate, elastomers based on a copolymer of ethylene and propylene, or elastomers based on a triple copolymer of ethylene, propylene and diene. In addition, mixtures of these elastomers with each other or with modifying elastomers may be provided. Elastic laminates are also suitable for use as material in belt parts 8, 16. Such laminates may have one or two or more layers of nonwoven material that can be attached to a layer of elastic material, preferably between at least two layers of nonwoven material. In the case where only one layer of nonwoven material is used in such a laminate, it is preferable that the layer of nonwoven material faces the carrier when the product is configured for use in order to increase user comfort. The elastic layer may be selected from threads, adhesives or films. Preferred elastomeric materials for the elastic layer are olefin elastomers, for example ethylene propylene elastomers, triple ethylene propylene diene rubbers, elastomers based on metallocenes and polyolefins, or elastomers based on a copolymer of ethylene and vinyl acetate, or copolymers such as styrene and isoprene copolymer block copolymerene with alternating blocks and a copolymer of styrene and ethylene / butylene with alternating blocks, or polyurethanes or mixtures. In addition, all elastomeric materials having an elasticity of from 10 to 500% may be suitable for the present invention.

As already mentioned, the detachable connection means 28, 29 or 27 according to any one of the embodiments of the invention can be made with the possibility of breaking them (without the possibility of re-bonding) when disconnected, or they can be made with the possibility of their re-bonding to increase the length of any of two or both parts of the belt 8, 16 to a length intermediate between the fully increased length and the length in the folded configuration. In any case, when the parts of the belt are held in a folded configuration, they must be held at least to the extent that they withstand the tensile separating force that can occur, for example, during transportation. On the other hand, they should be held in a sufficiently weak degree so that the user can easily disconnect them without causing damage to the product or the parts of the belt themselves. To this end, any fastening elements or means that form a detachable connection means must be able to separate them under the action of a force of approximately 3 to 15 N. It has been found that the bonds or connections used for the detachable connection means must have resistance to separation, providing a minimum resistance of 3 N, to maintain the integrity of the product during transportation and handling, while comfort for use the body and preventing damage to the product are best achieved when the forces required to deploy the product are less than 15 N. These forces are used to determine the absolute tensile force applied to a belt section 25 mm wide in the product plane in such a direction as to separate two elements, that is, at an angle of 180 ° to the place of connection (seam) or connection. In addition, it is preferable that the forces causing the separation of the releasable connection means are from 4 to 10 N and, in addition, preferably from 5 to 7 N. A force of 5-6 N or about 5 N, or about 6 N, can to be preferred. Bond strength (bond strength) may vary for belts that have a width that is greater or less than 25 mm. In particular, the relationship between the change in width and the change in bond strength should be linear, while there is a percentage between the strength values given for an example belt with a width of 25 mm and the force values given above. In other words, the force required to separate the detachable fastener is increased by approximately ten percent, respectively, can be used when increasing the width of the belt by about ten percent. The test method to be used to determine the above stratifying separation forces may be a test method in accordance with ASTM D 1876-72.

Figures 6 and 3 show an illustration of a garment with a don-on configuration in which the front panel can be placed at the rear side of the wearer's body. The connection between the belt portions 8, 16 and the front panel 4 can be made by any suitable means used as an alternative to the illustrated panel fastening elements 25, 26. In particular, fastening elements can be provided on the belt parts 8, 16 themselves or on both parts of the belt and the front panel 4.

Variants of the above examples, which are not shown, may be provided without departing from the scope of the present invention. In particular, the product may be provided with a number of means of connection or fastening elements for the implementation of structures and functions according to the attached claims.
