For the sake of simplicity, we use strips cut in the longitudinal, transverse, and 45-degree diagonal directions to measure omnidirectional extensibility. The absorptive core 42 (e.g., Flyent) is preferably omnidirectionally stretchable and extensible. When the stretching force is removed, the absorptive core 42 may (but may not) fully return to its original size without stretching. This characteristic can be expressed by the deformation percentage (%) of the core material. The S-Lent material has a deformation degree of less than or equal to about 10 ° / Q in the longitudinal direction, the transverse direction, and the diagonal direction. The absorptive core 42 (for example, Flint) is preferably highly elastic and foldable.

The Flyent material has the appearance of "swell" on one side and the side is quite flat. Within 20 of the sanitary napkin, the rich Any side of the Lyent material can be adjacent to the top sheet 38. Since the absorptive core material is originally extensible in all directions, there is no need to modify it in specific circumstances in order to make the Flint material Can be used as an absorbent core 42 to provide additional absorption capacity. This can be achieved in several ways Achieved, but not limited to them. In a specific example, a fabric or strip of an extensible material can be attached to the lower side of the Flyent material. In this specific example, the additional The surface of the extensible fabric or strip is placed adjacent to the Flyent material (that is, its inner surface), and the absorbent gel material is placed on it. Therefore, the additional fabric or strip The material system can make the absorptive gel material "trapped", or keep it in a position adjacent to the lower side of the Flyent material. In a preferred way of this specific example, the extensible material It consists of a rectangular strip of non-woven material that is ventilated. The width of the strip is about 2 inches (about 5 cm) and the length is about 6.25 inches (about 16 cm).

The extensible portion connected by the curled seal 78 is to extend the amount of the sanitary napkin by 20 (for example, see 4 lateral extensibility on the end region). (However, the curled seal 78 can make the component stretch in multiple directions.) Therefore, the curled seal 78 can be regarded as a stretchable curled seal (though if it is not used in combination with the stretchable component, 菽The curled seal 78 is not inherently malleable) ^ The curled seal preferably includes a liquid-permeable seal. The curled seal 78 preferably includes a sinusoidal seal line, and its direction is along at least one of the top sheet 38 or the back sheet 40 that is compressed and / or fused with each other. The curled seal 78 shown in Fig. I has a sinusoidal shape, preferably arranged in a generally curved configuration. Other patterns such as continuous sinusoidal patterns can also be used. Since the sinusoidal configuration can give the curled seal 78 a "relaxing force", it can be stretched before it is at least partially straightened. Therefore, the curled seal 78 can make the sanitary napkin adjacent to it. It is an extension, but this statement is not intended to be bound by any particular theory. Many variations of the extensible curl seal 78 can be used. For example, a curved seal may be placed to surround all or any portion of the periphery of the sanitary napkin, including the distal edge of the wing (to be described below). In addition to the sine curve pattern, other appropriate patterns that can provide the required "relaxation force" are also available. -30- This paper size applies to the Chinese National Standard (CNS) Λ4 specification (2.0 × 297 mm) ( (Please read the notes on the back before filling in this page) -11 409052av V. Description of the Invention (28) The use of 'including jagged patterns is not limited to this. The curly seal 78 has a sinusoidal (or other) pattern that can vary in bandwidth, amplitude, and frequency. In addition, a plurality of sinusoidal wave lines (or wave lines with other shapes) may be adjacent to each other in a phase arrangement. Multiple curled seals can be used to ensure that after processing, a continuous seal will be wrapped around the desired portion of the sanitary napkin. For example, curled seals may be cut during the manufacturing process. In the final cutting operation procedure (or when "the last cut"), the trailing edge portion of the sanitary napkin fabric is cut to make individual sanitary napkins. At this time, it is usually the most likely to occur. Case of broken curled seal. The function of the plurality of curled seals is to ensure that liquid does not penetrate the curled seal 78 by capillary action even if a part of the curled seal is cut during the manufacturing process. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (#Read the precautions on the back before filling this page) In other specific examples, the continuous sinusoidal curly seal can be joined with discontinuous (or intermittent) Pattern combination. The discontinuous joining pattern may be in the form of a discontinuous sinusoidal wave line, or other suitable discontinuous patterns. The discontinuous pattern needs to have a proper configuration. If the curled seal is cut during the manufacturing process, the discontinuous pattern can provide a tortuous flow path to surround any possible penetration by capillary action. The liquid of the curled seal. Since the cutting point where the last knife fell on the curled object is not absolute, these patterns can also make the manufacturing elasticity larger. This extensible curled front 78 offers several advantages, including but not limited to the following. As a matter of course, the extensible curled seal 78 forms a liquid-impermeable barrier, so that the liquid cannot seep through the end 2S of the sanitary napkin 20 by capillary action.

Sold by 40905 _________B7 V. Description of the invention (29) The components of raw cotton are extensible, even if they are continuous. In the past, it was necessary to use discontinuous bonding patterns so as not to hinder the ability of the stretchable part of the stretchable absorbent article to expand. The extensible curled seal 78 also helps to avoid the undesirable tendency of the trailing edge portion of the sanitary napkin to bend over the rest of the main body portion. The reason why this happens is because the extensible curled seal 78 can eliminate the difference in extensibility between the flange 76 and the rest of the main body portion 22. These differences will cause the flange 76 to be in the main body. Section 22 produces curl when stretched, however this statement is not intended to be bound by any particular theory. The sanitary napkin 20 shown in Figs. 1 to 4 also includes a pair of edge wings 24 attached to the main portion 22. The edge wing 24 extends outward beyond the longitudinal side edge 26 of the main body portion 22, from their proximal edge 24A to their distal edge (or "open end") 24B. The edge wing 24 extends outward from at least the central region 36 of the main body portion 22. &gt; As shown in Fig. 1, each edge wing 24 is divided into a front half 54 and a rear half 56 by the lateral centerline T! ^ May be consistent with the main horizontal centerline T of the sanitary napkin, but in this case, it is not necessarily necessary to establish a marginal wing 24 that is connected (or combined) with the main body portion 22 along the joint. It is usually a vertical direction (or "longitudinal j") connection, such as the connection line 68. As used herein, the term "connection" (or "connection line") means that the edge 24 extends from or is connected to To the area of the main body portion 22.

Description of the invention (3〇); By attaching one element to the intervening part, and then sequentially attaching to another element, the element is indirectly fixed to the other Component configuration: And—the 7C component and another component are in a complete and integrated configuration, that is, the component is a necessary part of another component. Preferably, the details shown in Figures 丨 to 4 In the example, the edge wing 24 and the main body portion 22 are integrally integrated (that is, 'the edge wing 24 includes the entire extension of the top sheet 38 and the back sheet 40.) The top sheet 38 and the back sheet 40 can interact with each other in any suitable manner. For example, the edge can be formed by spreading the adhesive over the entire surface, or any suitable portion, to join the extensions of the top sheet 38 and the back sheet 40 that form the edge wings.

Invention Description (31) No. PCT US 96/15957. In a better specific example, when the edge wing 24 is wrapped around When the wearer's underwear is on the side edge, the sanitary napkin 20 has several improved characteristics, which can reduce the pressure on the main body portion 22 and the edge wings 24. As mentioned above, the improved characteristic is that the central region 36 of the main body portion 22 has lateral extensibility, so the central region 36 can be expanded to help the edge flaps 24 to be folded around the curved side edges of the wearer's underwear . As shown in FIG. 1, the lateral extensibility is better, and it can also extend outward from the central region 36 of the main body portion 22, beyond the longitudinal side edge 26 of the main body portion 22, and extend to the edge wings 24. In the specific example shown, this laterally extensible area preferably terminates in an area 70 surrounding the edge-wing attachment 82. The area 70 surrounding the edge flap adhesive is preferably tighter than the rest of the edge flap 24, which can help consumers handle the edge flap 24 during use. In the specific example shown, another improved characteristic is that, even if the side wing 24 and the main body portion 22 are integrated, they still have a ductile area 72, and the origin of it is located at The longitudinal side edges 42A of the absorptive core 42 of the sanitary napkin 20 are inward (ie, located in the second and third extension regions 46 and 48). There are several reasons why the stretchable region 72 is located inside the longitudinal side edge 42A of the absorbent core 42 of the sanitary napkin 20. First of all, relative to making the edge wings on the outside of the absorbent article have all the extensibility, by making the extensibility on the inside of the longitudinal side edge 42A of the absorbent core 42, the edge wings 24 can be significantly enhanced. Extensible. Second, when the extensibility is placed inside the longitudinal side edge 42A of the absorptive core 42, it can be more suitable for wearing more types of feet. • 34-scale is suitable for Chinese prison prison standard soap (CNS) Λ4 specifications.

Because the absorptive core is usually neither extensible nor too thick, it can be stretched to form a stretchable mesh tissue area. Therefore, a sanitary napkin with a complete marginal wings is intended to be located on the edge of the absorptive core. The internal scalability is a big problem. However, in the specific example shown in the figure, both the top sheet 38 and the back sheet 4 have a region where they can be developed and formed therein, by using the top sheet These problems can be overcome by extending the absorptive core 42 surrounded by the M and the moon sheet 40 and connecting the top sheet 38 and the odd sheet 40 to each other. The extensible portions of the top sheet and the back sheet are vertically aligned with the stretchable mesh tissue region in the top sheet 38, and the stretchable mesh tissue region in the top sheet 38 The extensible portions of the top sheet 38 and the back sheet 40, which are directly placed on the back sheet, can be connected to the absorptive core 42 and extend with the absorptive core. Alternatively, one or both of the top sheet 38 and the back sheet 40 may not be attached to the absorbent core 42 in these areas. Preferably, at least the backsheet 40 is not attached to the absorbent core 42 in these areas. In the specific example, another improved characteristic of the sanitary napkin 20 is the direction of the basic vector component of the ductility, which is in the corner region 86 of the edge wing 24 and the main part The adjacent part of 22 (second and third extensions 46 and 48). When the sanitary napkin 2 is displayed in a plan view, the curved area 86 of the edge wing appears at the intersection of the outer edge of the edge wing 24 and the longitudinal side edge 26 of the main body portion 22. The Baojiao area 8 6 includes not only these other corners, but also the surrounding area and the adjacent area inside the edge of the edge wing 24. It is not necessary at the intersection or boundary of these edges -35- This paper size is suitable for China® Jiabiaohua (CNS> Λ4 size (210X297 cm)) (Please read the precautions on the back before filling this page) Ordered by the Central Ministry of Economic Affairs, the Central Consumers ’Cooperative Consumer Cooperative Association, 40905 _________ _B7 V. Description of the invention (33) Forms a clear angle for marking. The -t zone of the sanitary napkins with marginal wings was issued to Lavash U.S. Patent No. 5,389,094, et al. Contains a more detailed description. In the specific example shown in the figure, the curved area 86 is located at the same position as the extensible area 72. In each specific example In the corner region 86, the direction of the basic vector component of the ductility may be substantially in the transverse direction, substantially in the longitudinal direction, or in a direction between the transverse and longitudinal directions. In the specific example shown, the direction of the basic vector component of the ductility in the corner region 86 is preferably the same as the direction of the adjacent extension region of the main portion 22. The extension regions are the second and the third. Three Extension Zones and 48 of Since this extension area is preferably symmetrical, the corresponding direction of this basic vector component is usually the same as the two corner areas 86 of each edge wing 24. The term "corresponding direction" means between the basic vector components The negative direction from the longitudinal centerline L. Therefore, the corresponding direction of the basic vector component of the ductility in the corner region 86 faces inward toward the transverse centerline τ of the sanitary napkin 20 at an angle A Direction.

The point that the basic vector component of the ductility in the angled area 86 is facing inward provides several advantages. When the edge wing 24 is folded around the curved side edge of the wearer's underwear, the extensibility can more effectively reduce the pressure on the edge wing 24 compared with many previous attempts to solve the problem. In particular, 'when the edge wing 24 is wrapped around the curved side edge of the lower part of the wearer's underwear', there will be a force applied to the main body of the sanitary napkin 20 and the edge wing 2 4 caused problems, the scalability is used to solve these problems D -36- -------------------------- -------- ----- This paper's standard is applicable to Chinese storehouse standard (('NS) A4 size (2 丨 0X297mm) (Please read the notes on the back first and fill in this card)

-1T 4090 Recorded by the Central Standards Bureau of the Ministry of Economic Affairs, M Industrial Cooperative Cooperative, Ltd. V. Description of the Invention (34) The problem of the ductility described in this article is to be solved-the problem is referred to herein as a flap or margin The "sudden fall off" of the wing ^ This is related to the edge wing adhesion 82 (described in more detail below), and its design purpose is to 'by attaching the edge wing 24 to the underside of the wearer's underwear Or on the opposite edge wing 'can ensure that the edge wing 24 surrounds the underwear. When the edge wing 24 is stacked around the side edge of the wearer's underwear, it will cause tension on the edge wing. This tension may cause the edge-wing adhesive 82 to lose its bonding force with the edge wings on the underside or the opposite side of the wearer's underwear, and become no longer in a state of attachment 'or "suddenly fall off". One attempt to eliminate the sudden detachment of the wing is to increase the strength of the edge wing adhesion 82. However, 'increasing the strength of the edge-wing adhesion 82 causes other problems. Another problem to be solved in the extensibility orientation described in this article is that when the edge flap 24 is wrapped around the side edge of the wearer's underwear, the tension generated by it will also act on the sanitary napkin 20 On the main part 22. This is particularly relevant for highly elastic sanitary napkins, such as the extensible sanitary napkins described herein. The tension acting on the main body portion 22 around the edge wings 24 may cause the end region of the main body portion ^ and "no longer have the adhesive force of the adhesive, and cannot be attached to the wearer. Underwear. This phenomenon causes the trailing edge 28 of the main body portion 22 to be folded or rolled around the main body portion.

The problem of D on the top of the other parts of 22 caused by a highly elastic sanitary napkin is shown in FIG. 6, which is caused by the tension caused by overlapping the edge flap 24. FIG. 6 shows a highly elastic sanitary napkin 20. It is known that the sanitary tampon for physiological use -37- The standard of this paper is suitable for 1¾¾ standard (CNS) A4 specification (210/297) ^ a — ~ '^ ~~~ — (Please read the precautions on the back before (Fill in this education) -5 Printed by the Ministry of Economic Affairs Standards Bureau Bing II Consumer Cooperative Co., Ltd. 40905 Total B7 V. Invention Description (35) The system has fate, but for simplicity, the fate is not shown in Figure 6 Because the main concern is the effect caused by the force applied to the main body portion 22, as shown in FIG. 6, the force caused by stacking the wing 24 can be one or two of the main body portion 22. The ends are pulled inward toward the transverse centerline and may cause the portions of the main body portion 22 to overlap each other. Adhesives for tight-fitting pants on the underwear-facing side 20B of the sanitary napkin may cause the The overlapped part is attached to the lower part of the main body part 22. From the shape of the main body part, it can be referred to as "Z-shaped crossover J 0 in this crossbow". The direction of the basic vector components in the corner region 86 can be substantially reduced or eliminated, and most of these problems have been known It can be attributed to the tension applied between the end region of the main body portion 22 and the portion of the edge wing 24, wherein the component of the edge wing 24 is fixed by the edge wing adhesive 82. At the horn The direction of the basic vector component i in the region 86 is preferably approximately parallel to the tension line between these parts of the sanitary napkin. This ductility can reduce the end region of the main wound 22 and the marginal wing. The tension between the parts of 24, among which C, 彖 wing 4 is fixed by the edge wing adhesive 82. In addition, the same as the second and third extension areas, the angle area 86 is acceptable. The direction of ductility is also inward towards the lateral centerline Ti of the wing. Some previous efforts have directed the direction of the stretchable part of the wing to the same direction as the wearer's underpants.

The Peilong taut material preferably has a thickness of 0.35 mm, a bending resistance of about 33 grams, and a Taber tautness of about 0.85 grams. Cm. The Peilong taut material can be placed between any two layers of the sanitary napkin 20. The Peilong taut material is preferably placed under the absorptive core 42 and is coupled to the underside of the absorptive core by an adhesive such as Fuler Adhesive 2031. The selective tensioner 90 shown in FIG. 4 can impart additional tightness to the longitudinal side edges of the absorbent core and the end regions 32 and 34 of the sanitary napkin 20 to reduce unwanted starts. And reduce or eliminate the problem of trailing edge "shrinkage" discussed above. The selective tensioner 90 can also give an enhanced "pulling force" to the area located along the longitudinal centerline of the sanitary napkin to improve contact with the wearer's body. It is believed that the reason why the enhanced pulling force is generated can be attributed to the appearance of the end tightening member 90, so that all the pulling force is concentrated on the longitudinal centerline between the inner edges of the tightening member 90. Within the area along the line 'however this statement is not intended to be bound by any particular theory. The tightly knitted area on the outer perimeter or on the edge of the sanitary napkin also helps to secure the sanitary napkin to the wearer's underpants. It should be understood, however, that if a non-stretchable material such as Perlon is used to provide tightness, the ductility of the tight-end area of the sanitary napkin 20 will be reduced or removed. However, a specific example of the sanitary napkin 20 can still function effectively, especially if a gap is left between the tensioner 90 and the direction along the longitudinal centerline L. This specific example can still be extended in the direction along the longitudinal centerline, or in the diagonal direction shown above. -47- This standard is applicable. ^^ 票 准 （CNS） 4 size (2 * 70 ^ 97mm) ---- (Please read the notes on the back of Jing first and fill out this book. 409Aq52 Printed by the Central Standards Bureau of the Ministry of Economic Affairs, J-Consumer Cooperatives.
