Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products, and in particular to absorbent trousers and hygiene products. Background Technology

[0002] Existing disposable absorbent pants, disposable baby diapers, and disposable adult pull-up pants on the market have issues with the construction of elastic components (such as elastic bands and non-woven fabric composites) in areas from the waist to the hips and buttocks. These elastic bands are either too fine or too thick. Because these overly fine or overly thick elastic bands are evenly distributed around the waist of the sanitary products, the local stress is too high. Prolonged wear may cause pressure marks in areas such as the waist, hips, abdomen, and buttocks, affecting wearing comfort. In addition, the dense distribution of elastic bands will lead to poor breathability of the product.

[0032] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described below.

[0033] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0034] Reference Figures 1 to 3 This utility model provides an absorbent pant body 1, including a pant body 1 and an absorbent core 2. The pant body 1 includes an inner layer 11, an elastic layer 3, and an outer layer 12. The inner layer 11 is the surface layer that directly contacts the skin, and the elastic layer 3 is disposed between the inner layer 11 and the outer layer 12. The pant body 1 is provided with a front waist area 13, an abdominal area 14, a hip area 15, a crotch area 16, a lower buttock area 18, a hip area 17, and a back waist area 19 along the product length direction. The absorbent core 2 is disposed in the crotch area 16. The elastic layer 3 is provided with a number of waist elastics 31, abdominal elastics 32, hip elastics 33, hip elastics 34, and upper hip elastics 35. The number and spacing of elastics on the elastic layer 3 are set according to the needs of different areas. Specifically, the average spacing of any 10 consecutive elastics is greater than 3mm to ensure overall breathability.

[0035] Reference Figure 1 and Figure 2 Furthermore, the front waist area 13 and the rear waist area 19 are each provided with 6-9 waist elastic bands 31, and the average spacing of the waist elastic bands 31 is 2-4mm.

[0036] Furthermore, the waist elastic band 31 has a fiber fineness of 600-1000 denier and a stretch ratio of 2-4 times.

[0037] The front waistband 13 and the back waistband 19 are connected to form the waistband. The waistband is the area of ​​greatest stress for the absorbent trousers 1 and plays a major role in load-bearing. The elastic band 31 in the waistband is made of elastic with a high fiber fineness to ensure the reliability of the load-bearing capacity of the waistband. The spacing between the elastic bands in the waistband is set to be small. The thicker individual elastic bands and the denser arrangement make them less likely to break during production or use. Even if a single elastic band fails, the dense arrangement can be shared by other elastic bands to provide elasticity and ensure the continuity of function.

[0038] The abdominal region 14 is provided with 20-40 abdominal elastic bands 32, and the abdominal region 14 is alternately provided with a first dense region 321 and a first sparse region 322. The average spacing of the abdominal elastic bands 32 in the first dense region 321 is 2.8-4.5mm, and the average spacing of the abdominal elastic bands 32 in the first sparse region 322 is 6-12mm.

[0039] For example, the front waist area 13 and the back waist area 19 are each provided with 9 waist elastic bands 31. The abdominal area 14 is provided with 26 abdominal elastic bands 32, and the spacing of the first dense area 321 is set to 3 mm, and the spacing of the first sparse area 322 is set to 6 mm. Specifically, the 1st to 9th elastic bands are waist elastic bands 31, the 10th to 18th elastic bands are abdominal elastic bands 32 in the first dense area 321, and their spacing is set to 3 mm; the 18th to 19th elastic bands are abdominal elastic bands 32 in the first sparse area 322, and their spacing is set to greater than or equal to 6 mm. The 19th to 27th, 27th to 28th, 28th to 36th, and 36th to 37th elastic bands are alternately set as the first dense area 321 and the first sparse area 322 according to the above spacing.

[0040] In the abdominal area 14, a dense-sparse elastic band arrangement is formed. The densely elastic areas provide the main support and fixation, ensuring that the product does not slip down. In the sparsely elastic areas, when the abdomen expands (such as when inhaling or sitting), these areas can stretch more easily and to a greater extent, generating less recoil force and achieving a dynamic fit with the body's curves. This reduces the feeling of restriction and pressure caused by a single, uniform high elasticity. Furthermore, the dense-sparse elastic band arrangement disperses concentrated pressure to different areas, effectively avoiding the overall tightness caused by uniform pressure distribution across the entire abdomen. This effectively reduces skin indentations. In the first sparse area 322, the abdominal elastic bands 32 have a larger spacing, preserving the softness and breathability of the non-woven fabric, so that the skin does not come into contact with a single, taut elastic band, resulting in a more comfortable feel. In addition, the larger spacing of the elastic bands facilitates air circulation, reducing the discomfort of the abdominal skin being in a stuffy environment for a long time, further enhancing the wearing experience.

[0041] Furthermore, the abdominal elastic band 32 has a fiber fineness of 80-300 denier and a stretch ratio of 2-4 times.

[0042] Thinner elastic bands are used for the abdominal elastic band 32, which effectively reduces friction and marks caused by the elastic band, improving wearing comfort; and the stretch ratio is set relatively large, so that the abdominal elastic band 32 can be stretched relatively long, but the recoil stress is relatively small, which can effectively adapt to the curves of the body.

[0043] Furthermore, the hip area 15 is provided with 3-9 hip elastic bands 33, the average spacing between adjacent hip elastic bands 33 is 2-6mm, the fiber fineness of the hip elastic bands 33 is 80-300 denier, and the elongation ratio is 2-4 times.

[0044] In one specific embodiment, the hip area 15 is provided with 3 hip elastic bands 33, and the spacing between adjacent hip elastic bands 33 is set to 6mm.

[0045] Alternatively, the hip area 15 is provided with 6 hip elastic bands 33, and the spacing between adjacent hip elastic bands 33 is set to 4mm;

[0046] Alternatively, the hip area 15 may be provided with 9 hip elastic bands 33, with the spacing between adjacent hip elastic bands 33 set to 2mm.

[0047] The hip area 15 corresponds to the hip joint movement area of ​​the human body. It is required to be able to adapt to the movement of the human joint. The hip area 15 is provided with relatively dense hip elastic bands 33, which can play a supporting role and prevent the product from sliding or shifting during the activity.

[0048] Furthermore, the buttock area 17 is provided with 20-30 buttock elastic bands 34, and the buttock area 17 is alternately provided with a second dense area 341 and a second sparse area 342. The average spacing of the buttock elastic bands 34 in the second dense area 341 is 2.8-4.5mm, and the average spacing of the buttock elastic bands 34 in the second sparse area 342 is 6-12mm.

[0049] The elastic band for the buttocks has a fiber fineness of 80-300 denier and a stretch ratio of 2-4 times.

[0050] The hip elastic band 34 is set in the same way as the abdominal elastic band 32 in the abdominal area 14, and will not be described again here. In the hip area 17, a combination of dense and sparse elastic bands is used. The denser areas provide main support to prevent slippage, while the sparser areas allow for dynamic fit and significant stretch, significantly reducing pressure and constriction. Combined with thinner, higher-stretch elastic bands, breathability and wearing comfort are greatly improved while providing gentle fixation, perfectly adapting to changes in the hip curve.

[0051] Furthermore, the lower buttock area 18 is equipped with 3-9 upper buttock elastic bands 35, with an average spacing of 2-6mm between adjacent upper buttock elastic bands 35. The lower buttock area 18 works in conjunction with the hip area 15 to ensure effective support while conforming to the movement of the human joint.

[0052] The pants 1 have ventilation zones between at least the front waist area 13 and the abdominal area 14, and between the back waist area 19 and the hip area 17. The ventilation zones are provided with ventilation structures 4 for ventilation.

[0053] A breathable structure 4 is set on the pant body 1 to further enhance the breathability of the pant body 1 and improve wearing comfort.

[0054] In one embodiment, the breathable structure 4 is configured as a plurality of breathable holes, which are evenly distributed in the breathable area.

[0055] Furthermore, the spacing between adjacent vents is set to 0.1-20mm, and the total area of ​​each vent is 0.1-20mm².

[0056] In another embodiment, the breathable structure 4 is configured as a tangential structure, which can be one of a straight line, a curve, or a point break.

[0057] Furthermore, the spacing between adjacent tangent structures is 0.1-20mm, and the total length of the tangent structures is 0.5-20mm.

[0058] By punching holes or cutting lines in the waist area, air circulation channels are directly created, which can quickly remove moisture and heat from the skin surface of the waist and abdomen, effectively preventing sweat accumulation and helping to keep the skin dry and comfortable. It is especially suitable for wearing for a long time at night or for use in hot weather.

[0059] In this embodiment, the inner layer 11 and the outer layer 12 are made of nonwoven fabric, and the basis weight of the nonwoven fabric is set to 5gsm-30gsm. The nonwoven fabric can be made of nonwoven fabric produced by processes such as spunbond, meltblown, hot air, meltblown, hydroentangling, and needle punching, and is not limited to any one of these processes. The inner layer 11, the elastic layer 3, and the outer layer 12 can be laminated together by means of gluing, thermal bonding, or other methods.

[0060] The absorbent pants 1 of this utility model, by controlling the density and quantity distribution of elastic bands corresponding to different parts of the human body, makes the absorbent pants 1 more ergonomically designed. Furthermore, by using a dense-sparse staggered arrangement, the amount of elastic bands used is reduced, as is the amount of hot melt adhesive used, thereby improving the breathability of the product and reducing production costs.

[0061] This utility model also provides:

[0062] A hygiene product includes an absorbent pant body 1 with the structure described above, and the hygiene product can be configured as menstrual pants, disposable baby diapers, or adult pull-up pants, etc.

[0063] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
