Abstract
Description
Technical Field
[0001] This utility model relates to the field of disposable hygiene products, and in particular to baby pull-up pants, adult pull-up pants, women's sanitary pants, etc., specifically a type of shorts-shaped wearable item. Background Technology
[0002] Shorts-type garments (such as pull-up diapers) generally include an elastic outer body (also known as an elastic waistband), an absorbent core inside the outer body, and side wings on both sides of the outer body. In the unfolded state, the shorts-type garment has mutually perpendicular horizontal and vertical dimensions. Longitudinally, the outer body has a front waist corresponding to the wearer's abdomen, a back waist corresponding to the wearer's back, and a crotch area positioned between the front waist and back waist. Horizontally, each side edge of the outer body has an end area and a main body area located between the end areas. In the end areas, the front waist and back waist are sealed along their respective horizontal edges to form side closures, creating a pant-like shape with one waist opening and two leg openings. In the main body area, the front waist has a separation section (or tear-away section, which may consist of tear lines, hereinafter the same) on both sides, allowing the side wings to be repeatedly glued or separated (i.e., removed) on the non-skin side of the front waist. Before wearing, the side wings are glued to the front waist of the outer body; when wearing, the side wings are separated from the front waist of the outer body and the easy-tear seam is torn. After wearing, the side wings are glued to the non-skin side of the front waist of the outer body, so that it can be used as a diaper; or, when wearing, the easy-tear seam can be left untorn and worn directly on the body, so that it can be used as a pull-up diaper. In this way, pull-up diaper products like this can be used as dual-purpose clothing items.
[0003] For the aforementioned dual-purpose wearable articles, existing technologies typically employ two separate processes to form the side seal and the easy-tear line. Since the side seal is formed in the end area and the easy-tear line in the main body area, both need to be formed at two different stations. This can easily lead to phase deviations in the equipment's process direction, making it difficult to effectively control the distance between the easy-tear line and the side seal. Furthermore, the two-step process increases complexity and manufacturing costs. In addition, for wearable articles manufactured using this method, tearing the easy-tear line during wear leaves some outer material remaining near the side seal. This remaining material comes into contact with the skin (i.e., rubs against the skin), affecting wearing comfort.
[0004] Therefore, it is necessary to propose solutions to the problems of existing technologies. Utility Model Content

[0032] This application provides a shorts-type garment having orthogonal longitudinal, transverse, and thickness directions. The shorts-type garment has a front waist portion disposed longitudinally on the wearer's abdominal side and a back portion disposed on the wearer's back side. The front waist portion and the back portion are sealed along their transverse side edges to form side closures. The shorts-type garment includes an outer body and a pair of side wings disposed on both sides of the garment along its transverse direction. The side wings include a base material and hook elements. The outer body includes at least an inner layer sheet on the wearer's skin side and an outer layer sheet on the wearer's non-skin side. In the unfolded state, the outer body has a main body area and side wings disposed on both sides of the main body area. The end area; the side seal is located in the end area, the side seal includes a main body joint and a sealing cut; both the main body joint and the sealing cut extend longitudinally; the main body joint is located on the outer side of the sealing cut along the transverse direction; the sealing cut includes a sealing part and an easy-tear part, the sealing part and the easy-tear part at least partially overlap along the thickness direction, the sealing part is located on the substrate of the side wing, and the easy-tear part is located on the outer body of the front waist; the main body joint has a first pattern, the sealing cut has a second pattern, and the proportion of the total area of the first pattern of the main body joint in the end area is greater than the proportion of the total area of the second pattern of the sealing cut in the end area.
[0033] In this embodiment, the main body joint and the sealing part are integrally formed in the same process, thereby overcoming the technical problem of existing technologies that use two separate processes, resulting in phase deviation in the equipment flow direction and failure to effectively control the distance between the main body joint and the tearable part.

[0034] The following will provide a detailed description of a shorts-type garment provided in the embodiments of this application. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application.

In addition, regarding the accompanying drawings, for clearer explanation, the width, thickness, shape, etc., of each component may sometimes be schematically shown compared to the actual situation; however, this is only an example and not a limitation on the interpretation of this application. Moreover, the accompanying drawings are schematic representations of the implementation methods; therefore, the dimensions, spacing, or positional relationships of each component may be exaggerated or some component parts may be omitted from the illustration.
[0035] like Figure 1 and Figure 2 As shown, shorts-type clothing items have mutually orthogonal longitudinal, transverse, and thickness directions. The unfolded direction of the shorts-type clothing item is consistent with the longitudinal direction. The thickness direction includes the skin side and the non-skin side, such as... Figure 7 As shown, the skin side is the side of the skin that comes into contact with the wearer when wearing shorts-type clothing. Figure 7 The upper side (as shown), the non-skin side is the opposite side ( Figure 7 (As shown on the lower side). The shorts-type garment has a front waistband B1 positioned longitudinally on the wearer's abdomen, a back panel B2 positioned on the wearer's back, and a crotch area B3 positioned between the front waistband B1 and the back panel B2. Longitudinally, the shorts-type garment has a front body portion Fr and a back body portion Be positioned opposite each other, with the front body portion Fr corresponding to the front of the wearer's body and the back body portion Be corresponding to the back of the wearer's body. The front waistband B1 and the back panel B2 are closed along their respective transverse sides to form side closures 40, creating a pant-like shape with one waist opening and two leg openings, as shown. Figure 2 As shown.
[0036] The shorts-type garment includes an outer body 20 and an absorbent core 10 attached to the skin side of the outer body 20. The two ends of the absorbent core 10 overlap with the front waist section B1 and the back section B2, respectively. At the crotch section B3, the outer body 20 forms arc-shaped leg circumference lines 25 on both sides of the absorbent core 10, which better conforms to the wearer's leg contours.
[0037] like Figure 7 As shown, the absorbent body 10 includes a liquid-permeable sheet 11, a liquid-impermeable sheet 12, and an absorbent core 13 disposed between the liquid-permeable sheet 11 and the liquid-impermeable sheet 12. The outer body 20 is an outer elastomer, which includes at least an inner layer 21 disposed on the side closest to the wearer's skin and an outer layer 22 disposed on the side closest to the wearer's non-skin side. Figure 7In the illustrated embodiment, the external elastomer further includes a first elastic component 23 extending laterally between the inner layer 21 and the outer layer 22. The first elastic component 23 can be an elastic material such as a filamentous elastic spandex filament or a sheet-like elastic membrane. In this embodiment, the first elastic component 23 is a spandex filament extending laterally and arranged longitudinally at predetermined intervals. Of course, in other embodiments, the external elastomer only includes an inner layer 21 disposed on the side closest to the wearer's skin and an outer layer 22 disposed on the side closest to the wearer's non-skin side. The outer layer 22 is a non-stretchable nonwoven fabric, and the inner layer 21 is a stretchable nonwoven fabric. The stretchable nonwoven fabric is layered on the skin-side side of the non-stretchable nonwoven fabric, thereby giving the external elastomer a certain degree of elasticity.
[0038] The shorts-type garment also includes a pair of side wings 30. In some embodiments, the side wings 30 are located on the non-skin side of the outer garment 20 located at the front waist B1, such as... Figure 6A and Figure 6B In other embodiments, the side wing 30 is sandwiched between the outer body 20 located at the front waist B1 and the outer body 20 located at the rear back B2, such as... Figure 8A , Figure 8B , Figure 9A and Figure 9B .
[0039] The side wing 30 includes a substrate 31 and a hook element 32. The substrate 31 is composed of a single-layer sheet or a composite of multiple sheets, for example, it can be a single-layer or two-layer nonwoven fabric sheet; or a three-layer sheet component composed of two layers of nonwoven fabric sheets and a membrane material, wherein the membrane material is sandwiched between the two layers of nonwoven fabric sheets, and the membrane material can be a plastic film or a nylon film, etc. A hook element 32 is provided at the end of the substrate 31 of the side wing 30 (i.e., the end away from the side seal 40). The hook element 32 is rectangular, approximately trapezoidal, or other arbitrary shapes. Figure 5A , Figure 5C , Figure 5D and Figure 5E As shown, the hook element 32 is roughly trapezoidal. Figure 5B As shown, the hook element 32 is rectangular. Further, the hook element 32 is fixedly connected to the inner surface of the substrate 31 by at least one of hot melt adhesive, hot pressing, or ultrasonic welding. The outer edge of the substrate 31 has a curved edge portion 31a, as shown... Figures 5A-5E As shown. Laterally, the hook element 32 and the edge portion 31a have a predetermined interval, and the edge portion 31a has a portion protruding from the hook element 32, the position of which facilitates gripping during wearing. Longitudinally, both ends of the hook element 32 extend to the edge portion 31a of the substrate 31, as shown. Figure 5A , Figure 5C , Figure 5D and Figure 5EAs shown; or, along the longitudinal direction, there is a predetermined interval between the hook element 32 and the edge portion 31a of the substrate 31, such as... Figure 5B As shown. It should be noted that the hook element 32 has a hooked fabric, which consists of multiple small protrusions (one side of the hook element 32 has a hook-shaped fabric, which generates natural adhesion when it is attached to the side of the fleece-like fabric, and will naturally separate when subjected to external force (pulling by hand). These small protrusions can repeatedly adhere to or separate from the non-skin side (i.e., the outer layer 22) of the outer garment 20 located at the front waist B1 or the back B2. The non-woven fabric material used in the outer layer 22 can be intertwined with these small protrusions, thereby adhering to or separating it from the hook element 32, which helps in putting on and taking off shorts-type clothing.
[0040] like Figure 1 As shown, in the unfolded state, the shorts-type garment has a main body area A2 and end areas A1 located on both sides of the main body area A2 in the lateral direction. Specifically, the end areas A1 are located at the two outer edges of the outer body 20, and the main body area A2 is located between the two end areas A1. In this embodiment, the side sealing portion 40 is located in the end area A1. The side sealing portion 40 includes a main body joining portion 41 and a sealing portion 42. The main body joining portion 41 is located on the outer side of the sealing portion 42 in the lateral direction, and the main body joining portion 41 and the sealing portion 42 extend in the longitudinal direction, respectively. The sealing portion 42 includes a sealing portion 421 and an easy-tear portion 422. The sealing portion 421 and the easy-tear portion 422 at least partially overlap in the thickness direction. The sealing portion 421 is located on the base material 31 of the side wing 30, and the easy-tear portion 422 is located on the outer body 20 of the front waist portion B1, as shown. Figure 4A As shown.
[0041] like Figure 3 The main body joint 41 has a first floral pattern, and the sealing part 42 has a second floral pattern. The proportion of the total area of the first floral pattern distribution in the main body joint 41 in the end region A1 is greater than the proportion of the total area of the second floral pattern distribution in the sealing part 42 in the end region A1. Further, in the end region A1, the ratio of the total area of the second floral pattern distribution in the sealing part 42 to the total area of the first floral pattern distribution in the main body joint 41 ranges from 25% to 85%.
[0042] The first floral pattern of the main body joint 41 is at least one row of spaced patterns extending longitudinally. The shape of the first floral pattern can be striped, circular, oval, or other regular shapes, such as... Figures 5A-5E As shown. In one embodiment, when the number of columns of the first pattern is at least two, the first patterns in adjacent columns are arranged in a staggered manner along the horizontal direction, as shown. Figure 5A and Figure 5B As shown. In one embodiment, the number of columns of the first floral pattern can also be set to one column. When the shape of the first floral pattern of the main body joint 41 is strip-shaped, such as a rectangle or parallelogram, etc., Figures 5C to 5E As shown, the main body joint 41 forms an angle of 45° to 90° with the longitudinal direction. In one embodiment, the width of the first floral pattern distribution of the main body joint 41 is 1mm to 10mm in the transverse direction, and the distance between the first floral patterns of two adjacent main body joints 41 is 1mm to 5mm in the longitudinal direction. Figure 2 , Figures 4A to 4D In the embodiment shown, the main body joint 41 is formed by joining a pair of substrates 31 to the two side edges of the outer body 20 located at the front waist B1 and the rear back B2 respectively. The joining method can be hot pressing or ultrasonic process.
[0043] The second pattern of the sealing section 42 is arranged continuously or intermittently along the longitudinal direction, and the number of columns of the second pattern is at least one, such as... Figures 5A-5E As shown. In one embodiment, the second pattern of the sealing portion 42 has two or more columns, and the second patterns of adjacent columns are arranged alternately in the transverse direction, as shown. Figure 5D In one embodiment, the second floral pattern of the sealing portion 42 has a single column, such as... Figure 5E The second flower pattern is strip-shaped, such as rectangular or parallelogram, etc., and the sealing part 42 forms an angle of 0° to 20° with the longitudinal direction, preferably 0° to 15°. Figures 4A to 4D Laterally, the sealing portion 42 is located between the main body joint 41 and the hook element 32, and the sealing portion 42 is closer to the main body joint 41 than the hook element 32. Furthermore, as... Figures 5A-5E The sealing portion 42 has a transverse width of less than 1 mm, and the tear-resistant portion 422 in the sealing portion 42 is formed by cutting or melting. The sealing portion 42 and the main body joint portion 41 are integrally formed in one process at the same station (i.e., formed together). That is, the outer body 20 and the substrate 31 of the side wing 30 are joined by continuous or intermittent means, and the joining method can be hot pressing or ultrasonic processing. By adopting the above joining method, at the end area A1 of the front waist portion B1, a sealing portion 421 is formed on the substrate 31 of the side wing 30, and a tear-resistant portion 422 is formed on the outer body 20 (including at least the inner layer 21 and the outer layer 22). The tear-resistant portion 422 is part of the sealing portion 42. Therefore, when the side wing 30 and the outer body 20 located in the front waist portion B1 are pulled transversely, the tear-resistant portion 422 can be torn open. Figure 4CDuring the tearing process of the easy-tear portion 422, the external force (generated by the pulling action) is concentrated on the easy-tear portion 422, so that at the end area A1 of the front waist portion B1, the outer body 20 can easily break along the easy-tear portion 422, thereby dividing the outer body 20 into a part with the side wings 30 and another part without the side wings 30. In addition, in this embodiment, the melting points of the inner layer sheet 21 and the outer layer sheet 22 in the outer body 20 are both lower than the melting point of the substrate 31 of the side wings 30. As mentioned above, the sealing portion 42 is formed by hot pressing or ultrasonic processing. The material with the lower melting point (the inner layer sheet 21 and the outer layer sheet 22 of the outer body 20) is easy to melt, so the melted material (the inner layer sheet 21 and the outer layer sheet 22 of the outer body 20) is easier to break. In other words, the lower the melting point, the weaker the interaction force between the molecules or atoms inside the material when subjected to external force. These weaker binding forces are insufficient to resist external force, and the material is prone to deformation or breakage. Therefore, when the side wing 30 and the outer body 20 (inner layer 21 and outer layer 22) are pulled laterally in opposite directions, the material of the outer body 20 (inner layer 21 and outer layer 22) is more likely to break at the sealing part 42 compared with the material of the substrate 31 of the side wing 30.
[0044] In this embodiment, the main body joint 41 and the sealing / cutting part 42 are formed together at the same station using an ultrasonic welding process. This overcomes the technical problem in the prior art where two separate processes are used, resulting in phase deviation in the equipment flow direction and failure to effectively control the distance between the main body joint 41 and the tear-off part 422. By implementing the above solution, not only is the process flow simplified, but manufacturing costs are also saved.
[0045] Furthermore, in this embodiment, the weight range of the inner layer sheet 21 and the outer layer sheet 22 of the outer casing 20 is 10 g / m³. 2 ~60g / m 2 Preferably configured as 10g / m 2 ~30g / m 2 The basis weight of the substrate 31 of the side wing 30 ranges from 40 g / m². 2 ~90g / m 2 Preferably configured as 45g / m 2 ~80g / m 2 In other words, the basis weight of the inner layer 21 and outer layer 22 of the outer body 20 is lower than that of the base material 31 of the side wing 30. Therefore, when the outer body 20 (which includes at least the inner layer 21 and outer layer 22) is separated, the base material 31 of the side wing 30 is not easily broken, making the outer body 20 easy to tear at the tear-resistant portion 422.
[0046] like Figure 2 and Figure 7As shown, a side wing 30 is disposed on the non-skin side of the outer body 20 located at the front waist portion B1. The base material 31 and hook element 32 of the side wing 30 are disposed on the non-skin side of the front waist portion B1. The hook element 32 is removably attached to the non-skin side of the outer body 20 at the front waist portion B1. The melting point of the inner layer 21 of the outer body 20 located at the rear back portion B2 is greater than that of the inner layer 21 of the outer body 20 located at the front waist portion B1, and the melting point of the outer layer 22 of the outer body 20 located at the rear back portion B2 is greater than that of the outer layer 22 of the outer body 20 located at the front waist portion B1. Alternatively, see [reference needed]. Figure 6A and Figure 6B The outer body 20 located at the back B2 also includes an intermediate piece 2k, which is disposed between the inner layer 21 and the outer layer 22 of the outer body 20 located at the back B2. Since the outer body 20 located at the back B2 has an extra layer of material compared to the outer body 20 located at the front waist B1, the weight of the outer body 20 located at the back B2 is higher than that of the outer body 20 located at the front waist B1. In both cases (the melting point or weight of the back and front waist are different), during the formation of the tear-away portion 422, the outer body 20 located at the front waist is more prone to breakage when subjected to external force, while the outer body 20 located at the back B2 is less prone to breakage. Therefore, it does not affect other components of the shorts-type garment. Figures 4A-4D This shows the separation of the outer body 20 of the front waist section B1 and the formation of the waist opening. Among them, Figure 4A The image shows the state of the side wings 30 and the outer body 20 before wearing, with the hook element 32 of the side wings 30 attached to the non-skin side of the outer body 20 located at the front waist B1. Figure 4B This is shown to be done when wearing the garment, with the side wings 30 opened to separate the hook element 32 from the non-skin side of the outer garment 20. Figure 4C It is shown that when the outer body 20 and the side wings 30 located in the front waist section B1 are pulled laterally in opposite directions, the outer body 20 in the end area A1 of the front waist section B1 is separated at the sealing part 42 (tearable part 422). Figure 4D The diagram shows that, in the wearing state, the hook element 32 of the side wing 30, located at the front waist B1, is in contact with the non-skin side of the outer garment 20. It should be noted that, during actual wear, after the outer garment 20 is separated at the sealing portion 42 (tear-resistant portion 422), the contact position of the hook element 32 of the side wing 30 with the non-skin side of the outer garment 20 can be adjusted laterally to adjust the size of the waist opening.
[0047] like Figure 8A , Figure 8B , Figure 9A and Figure 9B as well as Figure 10As shown, when the tear-away portion 422 is not torn, the side wing 30 is sandwiched between the outer garment 20 located at the front waist B1 and the outer garment 20 located at the back B2. The hook element 32 is temporarily fixedly connected to the skin side of the outer garment 20 located at the front waist B1 or the back B2. When the tear-away portion 422 is torn, the hook element 32 is removably attached to the skin side or non-skin side of the outer garment 20 located at the front waist B1. Specifically, in one embodiment, see [reference needed]. Figure 8A and Figure 10 As shown, when the tear-away portion 422 is not torn, the substrate 31 of the side wing 30 and the hook element 32 are disposed on the skin side of the outer body 20 located at the front waist portion B1, and the hook element 32 is temporarily fixedly connected to the skin side of the outer body 20 located at the front waist portion B1; when the tear-away portion 422 is torn, as Figure 8B The hook element 32 is removably attached to the skin side of the outer body 20 located at the front waist B1. In another embodiment, such as... Figure 9A When the tear-away portion 422 is not torn, the hook element 32 is temporarily fixedly connected to the skin side of the outer body 20 located on the back B2; when the tear-away portion 422 is torn, as... Figure 9B The hook element 32 is removably attached to the non-skin side of the outer body 20 located at the front waist B1.
[0048] Continue reading Figure 1 The outer garment 20 also has a second elastic component 24 at the crotch B3. The second elastic component 24 is an elastic thread; in this embodiment, it is spandex. The second elastic component 24 extends at least from the back B2 to the crotch B3 along an arc-shaped curve. Of course, in other embodiments, it may extend from the front waist B1 to the crotch B3 along an arc-shaped curve, or the second elastic component 24 may consist of two sets extending from the back B2 to the crotch B3 and from the front waist B1 to the crotch B3 along an arc-shaped curve, depending on the style of the shorts-type garment. The arc-shaped curve of the second elastic component 24 matches the leg opening edge of the shorts-type garment, so that the extended shape of the second elastic component 24 matches the arc-shaped leg circumference line 25 of the human leg, better conforming to the wearer's leg contour. Figure 1In the illustrated embodiment, the second elastic component 24 extends along an arc from the back B2 to the crotch B3, improving the fit of the wearer's buttocks around the legs and enhancing wearing comfort. It should be noted that in the area where the outer garment 20 overlaps with the absorbent body 10, the elasticity of the first elastic component 23 of the outer garment 20 is disrupted or weakened due to pre-cutting, forming an elastically weakened area (not shown). Furthermore, in the crotch B3, the elasticity of the second elastic component 24 is disrupted or weakened due to pre-cutting, forming an elastically weakened area (not shown), thereby improving the smoothness of the composite of the absorbent body 10 and the outer garment 20.
