Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disposable sanitary products, especially sanitary napkins, mini pads, pantiliners and other fields, and particularly relates to an absorbent article. Background Art
[0002] The folding method of disposable absorbent articles (such as sanitary napkin products) in the existing market is that the sanitary napkin products are folded along a first folding line and a second folding line which extend along the length direction and are located on both sides in the width direction. When the sanitary napkin product is folded along the first folding line and the second folding line extending along the length direction, the length of the sanitary napkin product in the width direction becomes shorter, and then the sanitary napkin product is folded along a third folding line and a fourth folding line extending along the width direction to form an independent small package product, thus being convenient for carrying.
[0003] For conventional absorbent articles such as sanitary napkins, the absorbent core generally has the functions of water absorption and water locking, and the first folding line and the second folding line are respectively located on the sheets outside the absorbent core in the width direction, which means that the absorbent core will not be folded during the folding process in the width direction (folding along the first folding line and the second folding line). However, if the absorbent core is relatively wide (such as greater than 60 mm), during the process of folding the absorbent core together with the packaging sheet to form an independent small package product, at least the rear area (corresponding to the rear side of the body) of the sanitary napkin needs to be folded. Since the absorbent core has a liquid-absorbing material and a certain thickness, when the absorbent core is folded together with the packaging sheet, the formed independent small package product will also have a relatively thick size and may present in a convex or bulging form, which not only affects the appearance of the independent small package product, but also the relatively thick size of the independent small package product is likely to consume more materials during folding, thus increasing the production cost. In addition, when a relatively wide absorbent core is folded, the folding edge is prone to wrinkling and the contour is not clear, and the curved creases will affect the appearance of the surface material of the absorbent article.
[0004] Therefore, a solution to the problems of the existing technology needs to be proposed. Summary of the Utility Model

[0062] As Figure 1 and Figure 2 shown, an absorbent article 1 in an embodiment of the present utility model has a length direction, a width direction, and a thickness direction that intersect each other. The absorbent article 1 includes an absorbent body 30, a first sheet, and a second sheet. Among them, the first sheet is disposed on the skin side of the wearer of the absorbent body 30. Therefore, the first sheet can also be referred to as the top sheet 10. The second sheet is disposed on the non-skin side of the wearer of the absorbent body 30. Therefore, the second sheet can also be referred to as the back sheet 20.
[0063] The absorbent article 1 can be divided in the width direction into a main body region B1 and extension regions B2 connected to both sides of the main body region B1. And the absorbent article 1 can be divided in the length direction into a central absorbent region S2 and a first side region and a second side region connected to the central absorbent region. In the embodiment as shown in Figure 1 and Figure 2 , the first side region can be referred to as a rear side region S3, and the second side region can be referred to as a front side region S1, that is, the front side region S1 and the rear side region S3 are respectively connected to the front and rear sides of the central absorbent region S2. Among them, the front side region corresponds to the front side of the wearer's body, and the rear side region corresponds to the rear side of the wearer's body. It should be noted that in the thickness direction, the side in contact with the wearer is the skin side, and the side away from the wearer's skin side is the non-skin side.
[0064] Combined with Figure 3 shown in Embodiment 1, the absorbent article 1 includes a top sheet 10, a back sheet 20, an absorbent body 30, side sheet materials 40, a diversion part 50, and wing parts 60. In this embodiment, the absorbent article 1 is a sanitary napkin product. Among them, the top sheet 10 is disposed on the side of the absorbent body 30 in contact with the wearer's skin. The top sheet 10 is a liquid-permeable sheet through which the wearer's excrement can pass, and is generally made of a hydrophilic non-woven fabric. The back sheet 20 is disposed on the side of the absorbent body 30 away from the wearer's skin. The back sheet 20 is usually a liquid-impermeable sheet, and is generally made of materials such as a waterproof film. The absorbent body 30 is disposed between the top sheet 10 and the back sheet 20 and is used for absorbing human excrement. In Embodiment 1, the top sheet 10, the absorbent body 30, and the back sheet 20 are joined together by a conventional hot melt adhesive.
[0065] The absorbent body 30 includes a sheet member 31 and an absorbent core 32. Among them, the absorbent core 32 is composed of an absorbent material for absorbing excrement. Specifically, the absorbent core 32 can be an absorbent body formed by mixing fluff pulp fibers and a superabsorbent polymer (abbreviated as superabsorbent or SAP), or a prefabricated composite core, such as a prefabricated composite core containing a mixture of fluffy non-woven fabric and SAP, or containing a mixture of airlaid paper and SAP, or a mixture of non-woven fabric and SAP, or containing a mixture of fluffy non-woven fabric, airlaid paper, non-woven fabric, and SAP. The sheet member 31 wraps the absorbent core 32 and is generally made of materials such as toilet paper and absorbent paper. It should be noted that the absorbent core 32 is not necessarily wrapped by the sheet member 31, and the absorbent core 32 can also adopt a structure laminated with the sheet member 31.
[0066] It should be noted that the width dimension of the absorber 30 in the embodiment of the present utility model is at least greater than or equal to a preset dimension, which is 60 mm in this embodiment. That is to say, the structure of the absorbent article 1 herein is designed for an absorber with a relatively large width dimension. Of course, the width dimensions of different types of absorbent articles 1 (such as daily sanitary napkins, night-time sanitary napkins, etc.) may vary slightly.
[0067] At least in the rear side region S3, the absorber 30 has a first protruding portion 30a located in the extension region B2, and the first protruding portion 30a protrudes outward in the width direction compared with the absorber 30 located in the main body region B1. In other words, the first protruding portion 30a is the part that protrudes outward in the width direction compared with the absorber 30 located in the main body region B1.
[0068] Furthermore, as Figure 7 and Figure 11 shown, in the front side region S1, the absorber 30 has a second protruding portion 30b located in the extension region B2. The second protruding portion 30b protrudes outward in the width direction compared with the absorber 30 located in the main body region B1. In other words, the second protruding portion 30b is the part that protrudes outward in the width direction compared with the absorber 30 located in the main body region B1. Among them, the area of the second protruding portion 30b is smaller than the area of the first protruding portion 30a.
[0069] As Figure 1 shown, both sides of the absorbent article 1 in the width direction respectively have a first folding portion and a second folding portion extending in the length direction, and the first folding portion and the second folding portion at least partially overlap with the absorber 30 in the thickness direction. The first folding portion has a first reference folding line FL1, and the second folding portion has a second reference folding line FL2. The first folding portion and the second folding portion are used to fold both sides of the absorbent article 1 in the width direction along the first reference folding line FL1 and the second reference folding line FL2. The first folding portion and the second folding portion are at least located in the main body region B1. In the embodiments as Figure 1 and Figure 7 shown, the first folding portion and the second folding portion can be located at the boundary position between the main body region B1 and the extension region B2, that is, the first reference folding line FL1 and the second reference folding line FL2 are located at the boundary position between the main body region B1 and the extension region B2. In the embodiment as Figure 11 shown, the first folding portion and the second folding portion are located within the main body region B1, that is, the first reference folding line FL1 and the second reference folding line FL2 are located within the main body region B1. It should be noted that the main body region B1 is the main region for absorbing excreta; the regions on both sides of the main body region B1 are defined as the extension region B2.
[0070] As Figure 1 and Figure 2As shown, at least in the rear side region S3, both sides of the absorbent body 30 in the width direction are respectively provided with first embossing portions 33 arranged in the length direction, and the first embossing portions 33 are respectively located inside the first folding portion and the second folding portion in the width direction. Further, the first embossing portions 33 are arranged on a predetermined path line, and the path line is respectively parallel to the first reference folding line FL1 and the second reference folding line FL2. Of course, in some other embodiments, the path line may also be generally parallel to the first reference folding line FL1 and the second reference folding line FL2.
[0071] In some embodiments of the present invention, the first distance between the first reference folding line FL1 and its corresponding path line is less than or equal to 5 mm, and the second distance between the second reference folding line FL2 and its corresponding path line is less than or equal to 5 mm. In the embodiment as Figure 1 shown, the first distance between the first reference folding line FL1 and its corresponding path line is less than 5 mm, and the second distance between the second reference folding line FL2 and its corresponding path line is also less than 5 mm. That is to say, the first embossing portions 33 are located within a range of 5 mm inside the first reference folding line FL1 and the second reference folding line FL2 in the width direction.
[0072] In addition, the first embossing portions 33 are formed by arranging a plurality of regular graphics and / or a plurality of patterns. Among them, the graphics can be concepts including polygons such as points, lines, circles, triangles, and quadrilaterals. It should be noted that the above-mentioned lines are not limited to straight lines, but also include the concept of curved lines. And the patterns can include various patterns or patterns such as stars, hearts, leaves, and petals. When the first embossing portions 33 are arranged in a plurality of patterns, not only can the absorbent article 1 be adorably decorated, thereby improving the aesthetics, but also the depressive feeling of the wearer during menstruation can be alleviated. In addition, compared with the embossing portions arranged in a line shape, the arrangement of the first embossing portions 33 formed by a plurality of patterns is easier to be noticed, giving the wearer a further sense of reassurance.
[0073] In addition, in the thickness direction, the first embossing portions 33 press the sheet member 31 at least to the absorbent core 32 of the absorbent body 30, so that the absorbent core 32 is recessed from the skin side toward the non-skin side in the thickness direction, achieving an effect similar to a diversion groove, thereby guiding the excrement to diffuse toward the front and rear ends in the length direction, and alleviating the risk of leakage of the excrement from both sides of the absorbent body 30 in the width direction. It should be noted that in this embodiment, the first embossing portions 33 press the sheet member 31 (here the upper sheet member 31) to the absorbent core 32 of the absorbent body 30. In some other embodiments, the first embossing portions 33 press the upper sheet member 31 to the absorbent core 32 and the lower sheet member 31 (or other sheet layer materials other than the sheet member 31).
[0074] In some embodiments of the present utility model, by disposing a first embossing portion 33 having a plurality of graphic arrangements on a specified path line and densely disposing these graphics, the first embossing portion 33 formed by these graphic arrangements is used to introduce body fluids, thereby preventing the lateral leakage of excrement. And in some embodiments of the present utility model, the first embossing portion 33 can also be arranged in an alternating arrangement of a plurality of graphic structures and a plurality of pattern structures, improving the aesthetic degree while ensuring the function of preventing lateral leakage.
[0075] As Figure 3 shown in the first embodiment of the present utility model, the first embossing portion 33 is located in the rear side area S3. As Figure 7 shown in the second embodiment of the present utility model, the first embossing portion 33 is located in the front side area S1 and the rear side area S3. As Figure 11 shown in the third embodiment of the present utility model, the first embossing portion 33 extends from the front side area S1 through the central absorption area S2 to the rear side area S3.
[0076] Continuing to refer to Figure 1 and Figure 2 , a second embossing portion 34 is provided on the absorbent body 30. The second embossing portion 34 is formed by arranging a plurality of graphic embossing structures in a graphic shape and / or a plurality of pattern embossing structures in a pattern shape. Among them, the graphic embossing structure can include embossing structures of polygons such as points, lines, circles, triangles, and quadrilaterals. The pattern embossing structure can include embossing structures of various patterns or patterns such as stars, hearts, leaves, and petals. The second embossing portion 34 is used to emboss the absorbent body 30, so that the liquid-absorbing material (such as fluff pulp fibers) contained in the absorbent body 30 becomes more compact after embossing, is not easy to loosen, and has better absorption performance, thereby further preventing excrement from flowing to the outer edge of the absorbent article 1.
[0077] As Figure 1 and Figure 2 shown, the absorbent article 1 further includes a diversion portion 50. Along the length direction, the diversion portion 50 extends from the front side area S1 of the main body area B1 through the central absorption area S2 to the rear side area S3 to form a closed or unclosed annular structure. Along the thickness direction, the diversion portion 50 presses the top sheet 10 at least to the absorbent core 32 of the absorbent body 30. Along the width direction, the diversion portion 50 is located between the first reference folding line FL1 of the first folding portion and the second reference folding line FL2 of the second folding portion.
[0078] Furthermore, the diversion portion 50 is located between the first embossing portions 33 on both sides of the absorbent body 30 along the width direction. The diversion portion 50 has a certain pattern shape design, and this pattern shape forms a curve structure according to a predetermined rule. As Figure 1 and Figure 2 shown in the embodiment, the diversion portion 50 is a curve structure formed by connecting a plurality of bending portions, and the curve structure constitutes a pattern shape.
[0079] As shown Figure 2 in the figure, in the width direction, the absorbent article 1 further includes a pair of side sheets 40 disposed on the two outer sides in the width direction of the top sheet 10. Specifically, one end of the side sheet 40 is joined to the two outer sides in the width direction of the top sheet 10 and the side facing the wearer's skin by a hot melt adhesive or the like, and the other end of the side sheet 40 is joined to the side facing the wearer's skin of the back sheet 20 by a hot melt adhesive. The side sheet 40 can be made of a water-repellent material to further achieve the effect of preventing side leakage.
[0080] As shown Figure 1 in the figure, the absorbent article 1 further includes a heat-sealed portion 70, and the heat-sealed portion 70 is disposed on the outermost periphery of the absorbent article 1 and is arranged along the outer contour shape of the absorbent article 1 (i.e., consistent with the outer contour of the absorbent article 1). Among them, the heat-sealed portion 70 is formed by thermocompression of the side sheet 40 and the back sheet 20 along the outer periphery of the contour shape of the absorbent article 1. Further, the forming method of the heat-sealed portion 70 can include joining by using a heat embossing process and joining by using an ultrasonic process. The heat-sealed portion 70 is used to fix the outer edge of the absorbent article 1 and prevent the absorbent article 1 from cracking or opening during use.
[0081] In addition, as shown Figure 1 and Figure 2 in the figure, the absorbent article 1 further has wing portions 60, and the wing portions 60 are disposed in the extension area B2 to further achieve the effect of preventing side leakage.
[0082] The wrapping process of the absorbent article 1 will be further described below through several embodiments.
[0083] Embodiment 1
[0084] As shown Figure 3 , Figure 4 , Figure 5 and Figure 6 in the figure, the absorbent article 1 has a third folding portion and a fourth folding portion extending in the width direction. The absorbent article 1 further has a first folding portion and a second folding portion extending in the length direction. Among them, in the length direction, the first folding portion has a first reference folding line FL1, and the second folding portion has a second reference folding line FL2; in the width direction, the third folding portion has a third reference folding line FL3, and the fourth folding portion has a fourth reference folding line FL4.
[0085] First, the absorbent article 1 is folded at the first reference folding line FL1 and the second reference folding line FL2, so that the two sides of the absorbent article 1 in the width direction are relatively wrapped and partially overlap with the main body region B1, and the non-skin side surface of the folded absorbent article 1 is arranged to be placed on the packaging sheet 80. Then, in the state where the first folding portion and the second folding portion are folded, with the fourth folding portion extending in the width direction as a reference (specifically, with the fourth reference folding line FL4 of the fourth folding portion as a reference), the rear end edge of the absorbent article 1 and the rear end edge of the packaging sheet 80 are folded inward. Then, with the third folding portion extending in the width direction as a reference (specifically, with the third reference folding line FL3 of the third folding portion as a reference), the front end edge of the absorbent article 1 and the front end edge of the packaging sheet 80 are folded inward. Finally, the sticker (i.e., the packaging sticker) located at the front end edge of the packaging sheet 80 is adhered to the packaging sheet 80 folded inward to form an independent small package product.
[0086] Example 2
[0087] As Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, the absorbent article 1 has a third folding portion, a fourth folding portion extending in the width direction, and a fifth folding portion located between the third folding portion and the fourth folding portion and extending in the width direction. The absorbent article 1 also has a first folding portion and a second folding portion extending in the length direction. Among them, in the length direction, the first folding portion has a first reference folding line FL1, and the second folding portion has a second reference folding line FL2. In the width direction, the third folding portion has a third reference folding line FL3, the fourth folding portion has a fourth reference folding line FL4, and the fifth folding portion has a fifth reference folding line FL5. In the front side region S1, the absorbent body 30 has a second protruding portion 30b, and in the rear side region S3, the absorbent body 30 has a first protruding portion 30a. As Figures 7 to 10 shown in Example 2, the area of the second protruding portion 30b is small, and the area of the second protruding portion 30b is smaller than the area of the first protruding portion 30a.
[0088] First, the absorbent article 1 is folded at the first reference folding line FL1 and the second reference folding line FL2, so that both sides of the absorbent article 1 in the width direction are relatively wrapped, and partially overlap with the main body area B1. The non-skin side of the folded absorbent article 1 is configured to be placed on the packaging sheet 80. It should be noted that in the second embodiment, the area of the second protruding portion 30b is small and remains in an unfolded state during the folding process. Next, in the state where the first folding portion and the second folding portion are folded, with the fourth folding portion extending in the width direction as a reference (specifically, the fourth reference folding line FL4 of the fourth folding portion as a reference), the rear edge of the absorbent article 1 and the rear edge of the packaging sheet 80 are folded inward. Then, with the fifth folding portion extending in the width direction as a reference (specifically, the fifth reference folding line FL5 of the fifth folding portion as a reference), the absorbent article 1 and the packaging sheet 80 are folded inward again. Finally, with the third folding portion extending in the width direction as a reference (specifically, the third reference folding line FL3 of the third folding portion as a reference), the front edge of the absorbent article 1 and the front edge of the packaging sheet 80 are folded inward to form an independent small packet product.
[0089] It should be noted that from the wrapping process of the absorbent article 1 described in the above-mentioned first embodiment and the second embodiment, it can be seen that after the absorbent article 1 is folded and formed into an independent small packet product, the size in the length direction becomes shorter, thus achieving miniaturization, and therefore it is more convenient to carry. In addition, since the first embossing portion 33 is provided within a range of 5 mm inward in the width direction along the first reference folding line FL1 and the second reference folding line FL2, it helps the wrapping of the absorbent article 1, the wrapped edge is smoother, not easily loosened, the independent small packet product can present a thinner effect, and the wrapped edge contour is clear, without affecting the appearance of the surface material of the absorbent article. In addition, the first embossing portion 33 provided along the length direction can also be provided inward in the width direction along the third folding portion and the fourth folding portion according to actual needs, and designed into multiple absorbent body embossing portions, so that the product forms a smaller size of the independent small packet product after multiple foldings.
[0090] Embodiment Three
[0091] As Figure 11 、 Figure 12 and Figure 13 shown, the absorbent article 1 has a third folding portion, a fourth folding portion extending in the width direction, and a fifth folding portion located between the third folding portion and the fourth folding portion and extending in the width direction. The absorbent article 1 also has a first folding portion and a second folding portion extending in the length direction. As Figure 11As shown, the first folding portion and the second folding portion are located in the main body region B1. Along the length direction, the first folding portion has a first reference folding line FL1, and the second folding portion has a second reference folding line FL2. Along the width direction, the third folding portion has a third reference folding line FL3, the fourth folding portion has a fourth reference folding line FL4, and the fifth folding portion has a fifth reference folding line FL5. In the front side region S1, the absorbent body 30 has a second protruding portion 30b, and in the rear side region S3, the absorbent body 30 has a first protruding portion 30a. It should be noted that the area of the second protruding portion 30b in the front side region S1 in the third embodiment is larger than the area of the second protruding portion 30b in the front side region S1 in the second embodiment. In the third embodiment, the first embossing portion 33 extends from the front side region S1 through the central absorbent region S2 and to the rear side region S3.
[0092] First, before the absorbent article 1 is folded at the first reference folding line FL1 and the second reference folding line FL2, the non-skin side surface of the unfolded absorbent article 1 is arranged to be placed on the packaging sheet 80. Then, the absorbent article 1 and the packaging sheet 80 are folded together along the first reference folding line FL1 and the second reference folding line FL2, so that both sides of the absorbent article 1 in the width direction are relatively wrapped and partially overlap with the main body region B1. Then, in the state where the first folding portion and the second folding portion are folded, with the fourth folding portion extending in the width direction as a reference (specifically, with the fourth reference folding line FL4 of the fourth folding portion as a reference), the rear end edge of the absorbent article 1 and the rear end edge of the packaging sheet 80 are folded inward. Then, with the fifth folding portion extending in the width direction as a reference (specifically, with the fifth reference folding line FL5 of the fifth folding portion as a reference), the absorbent article 1 and the packaging sheet 80 are folded inward again. Finally, with the third folding portion extending in the width direction as a reference (specifically, with the third reference folding line FL3 of the third folding portion as a reference), the front end edge of the absorbent article 1 and the front end edge of the packaging sheet 80 are folded inward to form an independent small packet product.
[0093] It should be noted that from the folding process of the absorbent article 1 described in the third embodiment above, it can be seen that after the absorbent article 1 is folded and forms an independent small packet product, the dimensions in both the length direction and the width direction become shorter, forming a strip-shaped small packaging product with a smaller volume, such as Figure 13As shown. In addition, the first folding part and the second folding part are located within the main body area B1. The first embossing part 33 is arranged within a range of 5 mm on the inner side in the width direction of the first reference folding line FL1 and the second reference folding line FL2. The first embossing part 33 extends from the front side area S1 through the central absorption area S2 to the rear side area S3. The first embossing part 33 cooperates with the diversion part 50 to form a double diversion effect, thereby ensuring the dryness of the side of the absorbent body 30 facing the wearer's skin, further reducing the leakage probability of body fluids or excreta around the absorbent body 30 in the front, rear, left, and right directions, and improving the comfort and sense of security of the wearer.
