Description

Technical Field

[0001] The utility model relates to the technical field of underwear, in particular to a disposable trousers product. Background Art

[0002] At present, all trouser products on the market (such as trouser products for infants, women, adults, etc.) adopt conventional waist edge seal design to achieve normal wearing of the product and avoid unexpected falling. The conventional waist edge seal structure is usually achieved by aligning the front and rear waist non-woven fabrics at the waist edge seal position and pressing them together through high-temperature melting through an ultrasonic mold or a hot pressing mold, and the existing ultrasonic mold or hot pressing mold will use the pattern convexity generated by the pattern roller to achieve the compounding between the materials to increase the composite strength of the waist edge seal.

[0003] However, the conventional waist edge sealing structure mentioned above usually has the following problems:

[0004] 1) The strength of the edge seal structure is unstable, resulting in accidental rupture / tearing (too low strength) or inability to tear (too high strength) during daily use;

[0005] 2) Poor aesthetics, especially in summer when worn with light clothing, making consumers feel bulky and bloated;

[0006] 3) Poor privacy, the edge seal is easy to leave marks on the waist area;

[0007] 4) The edge seal structure has the disadvantage of being too thick and too hard, which causes it to leave marks when it contacts the skin and occasionally abrades the consumer's skin;

[0008] 5) Poor comfort.

The accompanying drawings are provided to present multiple embodiments of the utility model, but the accompanying drawings do not have to be drawn according to the size of the specific embodiments, and certain features may be enlarged, removed or partially cut to better illustrate and explain the disclosure of the utility model. Some components in the accompanying drawings can be adjusted in position according to actual needs without affecting the technical effect. The phrase "in the accompanying drawings" or similar terms appearing in the specification do not necessarily refer to all drawings or examples.

[0038] Certain directional terms used to describe the drawings below, such as "inner", "outer", "upper", "lower" and other directional terms will be understood to have their normal meanings and refer to those directions involved when the drawings are normally viewed. Unless otherwise specified, the directional terms described in this specification are basically in accordance with the conventional directions understood by those skilled in the art.

[0039] The terms "first", "first", "second", "second" and the like used in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0040] definition:

[0041] The terms "disposable" or "disposable" are used herein to describe absorbent articles that are not generally intended to be laundered or otherwise restored or reused as absorbent articles (e.g., they are intended to be discarded after a single use and may also be configured to be recycled, composted, or disposed of in other environmentally compatible manners). Embodiments of the absorbent pants described herein are disposable.

[0042] The term "pant product" (also referred to as "absorbent pants", "pant diapers" and "pull-on diapers") refers herein to disposable absorbent articles designed for adult wearers having a continuous peripheral waist opening and laterally opposed continuous peripheral leg openings. For the avoidance of doubt, adult incontinence products may be in the form of absorbent pants. Pants may be constructed with a continuous or closed waist opening and at least one continuous closed leg opening as packaged before the wearer puts on the article. Pants may be preformed by a variety of techniques, including but not limited to using any refastenable closure member and / or permanent closure member (e.g., sewing, heat bonding, pressure welding, adhesives, cohesive bonding, mechanical fasteners, etc.) to join the parts of the article together. Pants panels may be preformed anywhere along the circumference of the article in the waist region (e.g., side fastening or seaming, front waist fastening or seaming, rear waist fastening or seaming, or combinations thereof).

[0043] With respect to structural terms, the terms “disposed” or “provided with” are used herein to indicate that one or more elements are located in a particular place or position as a macroscopic integral structure with other elements or as a separate element joined to another element.

[0044] As used herein, the term "joined" includes configurations in which an element is directly secured to another element by attaching it directly to the other element, as well as configurations in which an element is indirectly secured to another element by attaching it to an intermediate member which is in turn attached to the other element.

[0045] As used herein, with respect to directional terms, with respect to a pant in an open configuration arranged to lie flat on a horizontal, flat surface, "longitudinal" means the direction generally perpendicular to a line tangent to each of the left leg opening edge and the right leg opening edge where the left leg opening edge and the right leg opening edge are closest to the front waist edge. With respect to a pant in an assembled configuration arranged to lie flat on a horizontal, flat surface with the front waist portion facing upward, "longitudinal" means the direction generally perpendicular to a line tangent to each of the left leg opening edge and the right leg opening edge where the left leg opening edge and the right leg opening edge are closest to the front waist edge. "Length" means a dimension measured along the longitudinal direction.

[0046] With respect to a pair of pants in an open configuration arranged to lie flat on a horizontal, flat surface, "lateral" means a direction generally parallel to a line tangent to each of the left leg opening edge and the right leg opening edge where the left leg opening edge and the right leg opening edge are closest to the front waist edge. With respect to a pair of pants in an assembled configuration arranged to lie flat on a horizontal, flat surface with the front waist portion facing upward, "lateral" means a direction generally parallel to a line tangent to each of the left leg opening edge and the right leg opening edge where the left leg opening edge and the right leg opening edge are closest to the front waist edge. "Width" means a dimension measured along the lateral direction.

[0047] As used herein, "integrally" means a configuration in which an element is produced from or by an article component or portion thereof, as opposed to being joined to a component. "Integrally formed" means producing an element from an underlying material or portion thereof by, for example, molding, forming, and / or reshaping the underlying material.

[0048] With regard to the material terms used herein, the term "nonwoven", "nonwoven" or "nonwoven fabric" refers to a material made of continuous (long) filaments (fibers) and / or discontinuous (short) filaments (fibers) using methods such as spunbond, meltblown, carding, etc. In some configurations, nonwoven fabrics may include polyolefin-based nonwoven fabrics, including but not limited to nonwoven fabrics with polypropylene fibers and / or polyethylene fibers and / or bicomponent fibers containing polyolefins. Non-limiting examples of suitable fibers include spunbond, spun web, meltblown, spunmelt, solvent spinning, electrospinning, carding, film fibrillation, melt film fibrillation, airflow, dry web, wet-laid short fibers, and other nonwoven web materials partially or completely formed by polymer fibers as known in the art, and their feasible combinations. Nonwoven fabrics do not have woven filaments or braided filament patterns. It should be understood that nonwoven fabrics with various basis weights can be used according to the methods herein. In various embodiments, the bicomponent fibers of the nonwoven material may include additives configured to be more readily sensitive to heating, such as by infrared light, which may aid, for example, in preheating or other heating of the nonwoven material as described herein.

[0049] "Body-facing" and "garment-facing" refer to the relative position of an element or the relative position of surfaces of an element or a group of elements, respectively. "Body-facing" means that the element or surface is closer to the wearer during wear than some other elements or surfaces. "Garment-facing" means that the element or surface is farther from the wearer during wear than some other elements or surfaces (i.e., the element or surface is near the wearer's clothing, which may be worn over a disposable absorbent article).

[0050] "Extensible material," "extensible material," or "stretchable material" are used interchangeably and refer to a material that, upon application of a biasing force, can be stretched to an elongated length of at least about 110% of its relaxed initial length (i.e., can be stretched to more than 10% of its initial length) without rupturing or breaking, and exhibits minimal recovery upon release of the applied force, i.e., recovers less than about 20% of its elongation without completely rupturing or breaking, as measured by EDANA method 20.2-89. In the event that such an extensible material recovers at least 40% of its elongation upon release of the applied force, the extensible material will be considered "elastic" or "elastomeric." For example, an elastic material having an initial length of 100 mm can extend to at least 150 mm, and upon removal of the force it retracts to a length of at least 130 mm (i.e., exhibits 40% recovery). In the event that the material recovers less than 40% of its elongation upon release of the applied force, the extensible material will be considered "substantially inelastic" or "substantially non-elastomeric." For example, an extensible material having an initial length of 100 mm may extend to at least 150 mm and retract to a length of at least 145 mm when the force is removed (ie, exhibit a 10% recovery).

[0051] As used herein, the term "bond" refers to the joining, adhering, connecting, attaching, etc. of two elements. Two elements will be considered to be bonded together when they are directly joined, adhered, connected, attached, etc. to each other or indirectly to each other, such as when bonded to an intermediate element. Bonding can be performed via, for example, adhesives, pressure bonds, heat bonds, ultrasonic bonds, splicing, stitching, and / or welding.

[0052] The term "open" means that the opposing waist regions are not initially joined to form a continuous waist opening and leg openings prior to or during application of the article to a wearer.

[0053] The term "closed" means that the opposing waist regions are permanently or refastenably joined when encapsulated to form a continuous waist opening and leg openings.

[0054] As used herein, the terms “substantially” or “approximately” mean that the referenced parameters or values ​​do not need to be achieved precisely, but deviations or variations (including, for example, tolerances, measurement errors, measurement precision limitations, and other factors known to those skilled in the art) may occur in an amount that does not interfere with the effect desired to be provided by the described features.

[0055] Figure 1 FIG. 1 is a flat view of an embodiment of a trouser piece of a disposable trouser product provided by the utility model, wherein the trouser product is in an open state. Figure 1The disposable trousers product shown in the figure is assembled by integrally formed trousers pieces, and the trousers product formed after the assembly is as follows Figures 2 to 7 and Fig.12 As shown, the disposable pant product includes a front waist region 12, a rear waist region 14 and a crotch region 18 arranged between the front waist region 12 and the rear waist region 14.

[0056] Wherein, the front waist region 12 and the back waist region 14 are towards the side of the wearer or the side facing the body, i.e. the inner waistline, and are optionally made of nonwoven fabrics and elastomeric materials (such as waist elastic bands) are optionally arranged in the front waist region 12 and / or the back waist region 14. The front waist region 12 and the back waist region 14 are away from the side of the wearer or the side facing the clothes, i.e. the outer waistline, and are optionally respectively formed with the corresponding inner waistline, for example, by a glue composite form, to form a waist composite layer, thereby obtaining the front waist region 12 and the back waist region 14 of the trousers piece. Of course, those skilled in the art can understand that this disposable trousers piece can also be made by other corresponding material structure layers and processes. The crotch area 18 optionally includes an absorbent layer made of absorbent material, and this absorbent layer can only be located in the crotch area or distributed in the whole trousers piece. Regarding this, those skilled in the art can design as needed.

[0057] Further, the front waist region 12 has a first edge portion 120, which is distributed at two transverse ends of the front waist region, and the first edge portion 120 is distributed along the longitudinal direction of the trousers. Figure 1 As shown, the longitudinal direction is the length direction of the trousers piece shown in the figure. The rear waist region 14 has a second edge portion 140, which is distributed at the two transverse ends of the rear waist region, and the second edge portion 140 is also distributed along the longitudinal direction of the trousers piece.

[0058] Specifically, it also includes an edge seal 16, which is configured to be formed by bending the first edge portion 120 and / or the second edge portion 140 along the transverse direction of the trouser piece 10 to overlap and engage with each other. Specifically, the edge seal 16 can be formed in the following ways: at the two transverse ends of the front waist region 12 and the back waist region 14 of the trouser piece, the first edge portion 120 is overlapped on the second edge portion 140; or the second edge portion 140 is overlapped on the first edge portion 120; or optionally, one of the first edge portions 120 is overlapped on the second edge portion 140, and the other first edge portion 120 is overlapped below the second edge portion 140.

[0059] The edge seal obtained by the above structure is basically kept horizontal relative to the front waist area or the back waist area (see Figure 8), so that the front waist region is connected to the back waist region to form the disposable trousers product. The term "stacked" means that one component overlaps and is stacked with another component. The term "horizontal" can be understood as the edge seal forms a basically smooth transition relative to the trousers piece and can be maintained on the same horizontal plane as the trousers piece. That is, the "edge seal" in the utility model does not form a convex ridge.

[0060] Further, in the embodiment shown in the present invention, the length of the rear waist region 14 along the transverse direction may be greater than the length of the front waist region 12 along the transverse direction (eg Figure 2 ), or the length of the front waist region 12 in the transverse direction is optionally greater than the length of the rear waist region 14 in the transverse direction (as shown in Figure 3 ), or the lengths of the front waist region 12 and the rear waist region 14 along the transverse direction are equal (as shown in Figures 6 to 7 shown).

[0061] Alternatively, Figure 2 1 is an assembly view of the trousers piece of the disposable trousers product provided by the utility model, wherein the trousers product is in a closed state, and the second edge portions are overlapped on the first edge portions. Figure 2 As shown, taking the edge seal 16 formed by overlapping the second edge portion 140 on the first edge portion 120 as an example, when the transverse length of the rear waist region 14 is greater than the transverse length of the front waist region 12, the second edge portion 140 is bent toward the first edge portion 120 along the transverse direction of the trouser piece 10 and overlapped on the first edge portion 120 (facing the clothing side) to form the edge seal 16 defining the overlapping area 160. It can also be understood that the second edge portion 140 is bent to cover the first edge portion 120, thereby forming the required edge seal 16. Of course, the edge seal 16 can also be formed in the following manner: the second edge portion 140 of the rear waist region 14 can be bent toward the first edge portion 120 and overlapped below the first edge portion 120 (facing the body side) of the front waist region 120 to form the edge seal 16 defining the overlapping area 160. This can be understood that the first edge portion 120 covers the bent second edge portion 140, thereby forming the required edge seal 16.

[0062] Alternatively, if Figure 3 As shown, Figure 3The figure is an assembly view of the trouser piece of the disposable trouser product provided by the utility model, which is observed from the wearing side of the product when the trouser piece is laid flat on a plane for assembly, and the figure shows the trouser product in a closed state. As shown in the figure, specifically, taking the edge seal 16 formed by overlapping the first edge portion 120 on the second edge portion 140 as an example, when the lateral length of the front waist region 12 is greater than the lateral length of the rear waist region 14, the first edge portion 120 is bent toward the second edge portion 140 along the lateral direction of the trouser piece and overlapped on the second edge portion 140 (facing the clothing side) to form the edge seal 16 defining the overlapping area 160. It can also be understood that the first edge portion 120 is bent to cover the second edge portion 140, thereby forming the required edge seal 16. Of course, the edge seal can also be formed in the following manner: the first edge portion 120 of the front waist region 120 can be bent toward the second edge portion 140 of the back waist region 14 and overlapped below the second edge portion 140 (facing the body side) of the back waist region 140 to form an edge seal 16 defining the overlapping area 160. This can be understood as the second edge portion 140 covering the bent first edge portion 120, thereby forming the required edge seal 16.

[0063] Additionally, when the lateral length of the front waist region 12 is equal to the lateral length of the back waist region 14 , the first edge portion 120 and the second edge portion 140 may be simultaneously bent toward each other and overlapped together to form the edge seal 16 (not shown).

[0064] Alternatively, Figures 6 to 7 This is an assembly view of the trouser piece of the disposable trouser product provided by the utility model. This view is obtained when the trouser piece is laid flat on a plane for assembly from the wearing side of the product. The figure shows the trouser product in a closed state.

[0065] Among them, Figure 6 to Figure 7 In the embodiment, one of the first edge portions 120 of the front waist region 12 is bent toward a corresponding second edge portion 140 of the back waist region 14 and overlapped below the second edge portion 140 (facing the body side), while another second edge portion 140 of the back waist region 14 is bent toward another first edge portion 120 of the front waist region 12 and overlapped below the first edge portion 120 (facing the body side). Alternatively, as an alternative embodiment, one of the first edge portions 120 of the front waist region 12 is bent toward a second edge portion 140 of a back waist region 14 and overlapped above the second edge portion 140 (facing the clothes side), while covering the second edge portion, while another second edge portion 140 of the back waist region 14 is bent toward another first edge portion 120 of the front waist region 12 and overlapped above the first edge portion 120 (facing the clothes side), while covering the first edge portion 120, and then the corresponding edge portions relative to each other are bonded to each other by gluing to form the edge seal 16, which example is not shown in the figure.

[0066] The disposable trousers product with the above-mentioned edge seal of the utility model can improve the wearing experience of the wearer, improve the aesthetics of the product, and eliminate the inconvenience of being heavy and bloated. In addition, since the disposable trousers product has the above-mentioned edge seal, the trousers product can perfectly fit the skin curve of the wearer at the edge seal, thereby effectively improving the problem that the traditional edge seal easily leaves marks on the waist skin of the wearer, and also improving the wearing comfort of the wearer.

[0067] Figure 8 yes Figure 1 An enlarged partial view of an edge seal of a disposable pant product is shown. Figure 8 The edge seal 16 shown is formed by evenly applying glue to the surfaces of the first edge portion 120 and the second edge portion 140 facing each other in the stacking area 160, and the formed edge seal 16 is an edge seal that is completely fitted to each other. In the stacking area 160 of the edge seal 16, a fitting portion 162 for forming a complete fit between the first edge portion 120 and the second edge portion 140 is partially provided on the surfaces facing each other. The fitting portion 162 can be constructed as a roughly rectangular structure. The term "complete fit" means that the first edge portion 120 and the second edge portion 140 are in complete surface-to-surface contact, for example, by gluing, without any separated parts. The above-mentioned gluing method adopted in the utility model is conducive to maintaining the structural stability of the edge seal and avoiding the occurrence of unexpected lack of strength.

[0068] For the above-mentioned joining methods, those skilled in the art will appreciate that gluing or bonding is a preferred joining method for joining the first edge portion 120 and the second edge portion 140. When the edge seal 16 is formed by gluing, the resulting edge seal 16 is more friendly to the skin in contact.

[0069] See again Figure 8 , wherein the edge seal 16 has a length d1 along the longitudinal direction of the trousers panel, wherein the length d1 is in the range of 130 mm to 180 mm. The edge seal 16 also has a width d2 along the transverse direction of the trousers panel 10, wherein the width d2 is in the range of 10 mm to 15 mm.

[0070] Fig. 9 FIG. 1 is a flat view of another embodiment of the trouser piece 10 of the disposable trousers product 1 provided by the present invention. Figure 1 The structure of the trousers shown is substantially the same, the main difference being the edge seal 16, Figure 1 The edge seal 16 shown is an edge seal in which the first edge portion 120 and the second edge portion 140 are completely in contact with each other. Fig. 9The edge seal 16 shown is an edge seal in which the first edge portion 120 and the second edge portion 140 are partially bonded. The edge seal 16 defines a stacking area 160, and the first edge portion 120 and the second edge portion 140 are partially provided with bonding portions 162 on the surfaces facing each other in the stacking area 160 for forming the edge seal 16 in which the two are partially bonded. The term "partial bonding" refers to a bonding method in which the first edge portion 120 and the second edge portion 140 are partially in surface contact with each other in the stacking area by, for example, gluing, wherein the bonded portions and the unbonded portions can be, for example, alternately spaced, and such a setting can avoid the occurrence of an undesirable excessive strength.

[0071] Fig.10 yes Fig. 9 FIG. 1 is a partial enlarged view of the edge seal 16 of the disposable pants product 1. Fig.10 As shown, in this embodiment, the first edge portion 120 and the second edge portion 140 are partially and evenly glued on the surfaces facing each other in the stacking area to form an edge seal 16 that is partially attached to each other. The partially attached edge seal 16 is formed with a plurality of attached portions 162, and each attached portion 160 in the edge seal 16 can be configured as a horizontal stripe structure (see Fig.10 ), each of the horizontal stripe-shaped laminating portions 162 extends in the transverse direction of the edge seal 16 and is spaced apart from each other in the longitudinal direction of the trouser piece 10 by a certain distance, preferably, each of the spacing distances is equal. That is, the plurality of horizontal stripe-shaped laminating portions 162 of the edge seal 16 are equally spaced apart in the longitudinal direction (for example, similar to the structure of a Venetian blind). In the edge seal 16 formed by partial laminating of the first edge portion 120 and the second edge portion 140 mentioned above, the laminating portion 162 has a width d3 in the transverse direction, d3 may be less than d2, and the width d3 may be, for example, in the range of 10 mm to 12 mm.

[0072] Alternatively or additionally, each of the bonding portions 162 of the edge seal 16 can also be constructed as a wavy stripe structure. Each of the wavy stripe bonding portions 162 extends in the transverse direction of the edge seal 16 and is spaced a certain distance apart from each other in the longitudinal direction of the trouser piece 10, preferably, each spacing distance is equal. That is, the plurality of wavy stripe bonding portions 162 of the edge seal 16 are equidistantly spaced along the longitudinal direction. The distance between each of the above-mentioned horizontal stripe-shaped and wavy stripe-shaped bonding portions 162 can preferably be between 2 and 8 mm. In the case where the first edge portion 120 and the second edge portion 140 are partially bonded with cloth glue, the total area of ​​the bonding portion 162 (or also referred to as the bonding portion) can account for 12% to 50% of the total area of ​​the edge seal.

[0073] Alternatively or additionally, each fitting portion 162 of the above-mentioned edge seal can also be constructed as a dot-shaped structure. Among them, each dot-shaped fitting portion 162 is spaced in the transverse direction of the edge seal, and can also be spaced in the longitudinal direction of the trouser piece. Preferably, each spacing distance is equal. That is, the multiple dot-shaped fitting portions 162 of the above-mentioned edge seal are equidistantly spaced in the longitudinal direction and / or the transverse direction. The dot-shaped fitting portions 162 can be collinearly distributed in the transverse and / or longitudinal directions. The dot-shaped structure of each fitting portion 162 can specifically be a triangle, a circle, a quadrilateral, an ellipse, etc. Under the inspiration of the utility model, those skilled in the art can also think of other alternative dot-shaped structures.

[0074] Fig.11 FIG. 1 is a flat view of another embodiment of the trouser piece 10 of the disposable trouser product 1 provided by the present invention. As shown in the figure, in addition to the difference in length between the front waist region 12 and the back waist region 14 in the transverse direction, Fig.11 The trousers panel 10 shown may have Figure 1 or Fig. 9 The trouser panels 10 shown have the same structure (particularly the edge seals).

[0075] Fig.12 1 is a schematic diagram of the disposable pants product provided by the utility model in the wearing state. Specifically, the view in the box in the figure shows the state of the edge seal 16 of the disposable pants product 1 in the wearing state. As shown in the figure, the edge seal 16 is generally kept substantially horizontal relative to the waist region (i.e., the part defined by the front waist region 12 and the back waist region 14 after the product is assembled), especially the circumferential surface of the waist region, and does not form a convex ridge portion protruding in the radial direction relative to the circumferential surface of the waist region.

[0076] The utility model provides a disposable trousers product, which improves the aesthetics of the product through a novel structural design, and enables the trousers product to perfectly conform to the skin curve of the wearer at the edge seal, thereby effectively improving the problem that the traditional edge seal easily leaves marks on the skin of the wearer's waist, while also improving the wearing comfort of the wearer and avoiding the possible strength incompatibility of the product.
