Description

Technical Field

[0001] The present invention relates to the technical field of nursing products, in particular to an adjustable open-and-close pull-up pants for adults. Background Art

[0002] The pull-up pants products currently on the market generally adopt an integrated pants structure design. The front waist area and the back waist area are welded and consolidated at the connecting parts on both sides through a hot melt welding process to form an overall structure similar to underwear.

[0003] While this design enhances the waistband's seal, replacing it requires mechanically tearing the welded areas on both sides, which is inconvenient. Due to the uneven stress distribution at the welded areas, stress concentration can easily occur during horizontal tearing, causing the tearing trajectory to deviate from the intended path. This can lead to accidental leakage of excrement, potentially contaminating the user's clothing and the surrounding environment.

[0004] In addition, existing pull-up pants products have some design deficiencies. First, the replacement operation must be carried out by completely taking off the pants, which constitutes a significant operational obstacle for disabled patients with limited mobility (such as critically ill bedridden patients, patients with motor dysfunction, etc.), which not only increases the workload of caregivers, but also may cause psychological discomfort to users. Secondly, there are many wrinkles at the waistline, which feel poor when in direct contact with the skin, and due to the repeated friction of the waistline folds, the user's comfort is low. Finally, the elastic modulus of the integrated waist structure is fixedly distributed, and it is impossible to perform dynamic pressure adjustment according to the user's body movements and body shape changes, thereby further reducing the user's comfort. Summary of the Invention

[0005] The object of the present invention is to provide an adjustable open-and-close pull-up pants for adults, aiming to solve the problem of low user comfort in the background art.

[0006] In order to solve the above technical problems, the present invention provides an adjustable open and close adult pull-up pants, comprising a base layer, a core arranged in the base layer, and two elastic waistbands arranged correspondingly at the upper and lower edges of the base layer, the elastic waistband comprising a breathable jacket extending left and right and a plurality of elastic strips spaced apart up and down and placed in the breathable jacket; the outer left and right parts of the elastic waistband at the upper edge of the base layer are provided with a first adhesive portion fixed to the elastic strip, and the outer left and right parts of the elastic waistband at the lower edge of the base layer are provided with a second adhesive portion fixed to the elastic strip, the second adhesive portion extending left and right and used for bonding the first adhesive portion.

[0007] As an improvement to the above solution, the cross section of the elastic strip is a trapezoid that is longer on the outside and shorter on the inside, and arc transitions are provided at the four corners of the cross section of the elastic strip.

[0008] As an improvement to the above solution, a plurality of connecting vertical bars are provided between two upper and lower adjacent elastic bars.

[0009] As an improvement to the above solution, the connecting vertical bars and the elastic bars are both provided with a plurality of elliptical through holes with their long axes extending vertically.

[0010] As an improvement to the above solution, the plurality of connecting vertical bars are arranged equidistantly on the left and right, and two adjacent elastic bars are arranged coaxially on the upper and lower sides.

[0011] As an improvement to the above solution, the outer layer of the breathable jacket is provided with a plurality of connection parts which are fixedly connected to the plurality of vertical connection bars in a one-to-one correspondence.

[0012] As an improvement to the above-mentioned solution, the left and right outer sides of the breathable jacket at the upper edge of the base layer are provided with openings for the elastic strip to extend out, the two first adhesive portions are fixedly connected to the two ends of the elastic strip, and the left and right outer sides of the breathable jacket at the lower edge of the base layer are fixedly connected to the two second adhesive portions and the left and right sides of the elastic strip.

[0013] As an improvement to the above solution, a plurality of semicircular protrusions are provided on the outer side of the elastic strip.

[0014] As an improvement to the above solution, luminous yarn is sewn on the outer side of the breathable jacket at the corresponding semicircular convex points.

[0015] As an improvement to the above solution, a pressure-sensitive paper in close contact with the core is provided in the base layer, and a portion of the outer side of the base layer corresponding to the pressure-sensitive paper is a transparent gauze.

[0016] From the above, it can be seen that the present invention provides an adjustable open and close adult pull-up pants that cooperates with the base layer, core body, elastic waist, breathable jacket, elastic strip, first adhesive part and second adhesive part, and adopts a split waistbelt setting, which does not require tearing the pull-up pants, making it convenient for users to wear and change. The elastic waist has fewer wrinkles, and at the same time, multiple elastic settings can increase and disperse the area of ​​the elastic waist tightening the user's waist, so that the elastic waist has less restraint on the user, thereby improving the user's comfort when using it; in addition, it can also perform dynamic pressure adjustment according to the user's body movements and body shape changes, reducing the impact on the user's comfort experience.

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown, an adjustable open-and-close adult pull-up pants according to an embodiment of the present invention comprises a base layer 1, a core 2 disposed within the base layer 1, and two elastic waistbands 3 disposed correspondingly at the upper and lower edges of the base layer 1. In fact, the base layer 1 comprises an outer layer and an inner layer, and the core 2 is placed between the inner and outer layers. The outer layer of the base layer 1 is usually made of a breathable and waterproof material, such as a breathable and water-impermeable film composited with a hydrophobic non-woven fabric, to prevent urine from overflowing and keep the user dry; the inner layer of the base layer 1 is made of a soft, hydrophilic non-woven fabric, so that the core 2 can absorb urine through the inner layer; the core 2 is usually made of a combination of fluffy non-woven fabric and a polymer water-absorbing resin, or a mixture of wood pulp fibers and a polymer water-absorbing resin and wrapped with a non-woven fabric to form a block structure for absorbing and retaining urine excreted by the human body.

[0026] It should be noted that the outer layer of the base layer 1 is the side of the base layer 1 close to and facing the human skin, and the inner layer of the base layer 1 is the side of the base layer 1 away from and facing away from the human skin; similarly, the inner side of the adjustable open and close adult pull-up pants in the embodiment of the present invention is also the side close to and facing the human skin and the outer side is also the side away from and facing away from the human skin, such as Figure 1 What is shown is a structural schematic diagram of an adjustable open-and-close adult pull-up pants in an embodiment of the present invention in a flattened state, where the side facing outward is the outer side and the side facing inward is the inner side.

[0027] The elastic waistband 3 includes a breathable jacket 4 extending left and right and a plurality of elastic strips 5 spaced apart and placed inside the breathable jacket 4. In fact, the breathable jacket 4 can be made of breathable and skin-friendly materials such as polypropylene non-woven fabric, polyethylene breathable film, composite breathable film, hot air non-woven fabric, etc., so that the elastic waistband 3 is more comfortable to contact with the user. At the same time, the plurality of elastic strips 5 spaced apart up and down are placed inside the breathable jacket 4, which provides sufficient elasticity while increasing and dispersing the area where the elastic waistband 3 tightens the user's waist, so that the elastic waistband 3 has less sense of restraint on the user, thereby improving the user's comfort when using it. Preferably, the gap between the two adjacent elastic strips 5 above and below is greater than the height of the elastic strip 5. The height of the elastic strip 5 refers to the following: Figure 1 The distance between the upper and lower sides of the elastic strip 5 makes the contact area between the elastic strip 5 and the user's waist more dispersed and reduces the sense of restraint of the elastic waist 3 on the user.

[0028] The elastic waistband 3 at the upper edge of the base layer 1 is provided with first adhesive sections 6 on the left and right sides thereof, which are fixed to the elastic strip 5. The elastic waistband 3 at the lower edge of the base layer 1 is provided with second adhesive sections 7 on the left and right sides thereof, which are fixed to the elastic strip 5. The second adhesive sections 7 extend left and right and are used to adhere to the first adhesive sections 6. In practice, the first adhesive sections 6 and the second adhesive sections 7 can function as the hook and loop sides of Velcro. When the first adhesive section 6 and the second adhesive section 7 come into contact, the hooks on the loop side embed into the fleece on the loop side, achieving adhesion. Separation of the loop side and the hook side can be achieved by tearing the loop side apart. The two elastic waistbands 3, through the cooperation of the first adhesive sections 6 and the second adhesive sections 7, can be combined into a 360-degree waistband, making it convenient for the user to wear and change. At the same time, since the multiple elastic strips 5 placed in the breathable jacket 4 cooperate with the first adhesive portion 6 or the second adhesive portion 7, the multiple elastic strips 5 connected to the first adhesive portion 6 can extend out of the breathable jacket 4, so that the corresponding breathable jacket 4 does not need to adapt to the expansion and contraction of the elastic strips 5, the wrinkles can be eliminated or smaller, and the touch is better when in contact with the user's skin. In addition, the second adhesive portion 7 is extended left and right, and can provide a bonding position for the first adhesive portion 6 within a certain left and right range, and can dynamically adjust the pressure according to the user's body movements and body shape changes. Preferably, the length of the second adhesive portion 7 is 2-4 times the length of the first adhesive portion 6 to provide a suitable left and right distance range for the user to adjust; preferably, the inner side of the first adhesive portion 6 is used to be bonded and connected to the outer side of the second adhesive portion 7, and a hard plate is provided on the outer side of the first adhesive portion 6. In fact, the hard plate can provide a flat and stable base, making the bonding between the first adhesive portion 6 and the second adhesive portion 7 more firm. The design of the hard plate makes it easier for the first adhesive portion 6 to align and fit with the second adhesive portion 7 during adhesion, and also facilitates quick tearing off when the diaper needs to be changed, reducing pulling and discomfort on the skin.

[0029] The adjustable openable and closeable adult pull-up pants of the present invention cooperate with each other through the base layer 1, the core 2, the elastic waist 3, the breathable jacket 4, the elastic strip 5, the first adhesive part 6 and the second adhesive part 7, and adopts a split waist belt setting, which does not require tearing the pull-up pants, making it convenient for users to wear and change. The elastic waist 3 has fewer wrinkles, and the multiple elastic settings can increase and disperse the area where the elastic waist 3 tightens the user's waist, so that the elastic waist 3 has less restraint on the user, thereby improving the user's comfort when using it; in addition, it can also perform dynamic pressure adjustment according to the user's body movements and body shape changes, reducing the impact on the user's comfort experience.

[0030] Specifically, the cross-section of the elastic strip 5 is preferably a trapezoidal shape, with a longer outer shape and a shorter inner shape, and the four corners of the cross-section of the elastic strip are provided with arc transitions. This arrangement can evenly distribute the pressure of the elastic strip 5 on the human skin, reduce friction and irritation, improve fit and stability, and enhance durability and comfort.

[0031] It's worth noting that multiple connecting bars 8 are preferably provided between two adjacent elastic strips 5. By separating the two adjacent elastic strips 5 with multiple connecting bars 8, misalignment and entanglement of the multiple elastic strips 5 within the same breathable jacket 4 can be prevented to a certain extent, ensuring wearer comfort. Preferably, the connecting bars 8 are integrally formed with the elastic strips 5, i.e., made of the same material as the elastic strips 5, achieving a synchronized expansion and contraction effect, reducing the discomfort associated with the addition of the connecting bars 8.

[0032] Furthermore, the connecting vertical strips 8 and the elastic strips 5 are preferably provided with a plurality of elliptical through holes 9 with their major axes extending vertically. In practice, as the elastic strips 5 and the connecting vertical strips 8 are extended in the left-right direction, the elliptical holes become larger along their minor axes, thereby ensuring the elasticity of the elastic strips 5 and their connection with the breathable jacket 4, providing more ventilation area, and enhancing the wearing comfort of the elastic waistband 3.

[0033] Furthermore, the plurality of connecting vertical bars 8 are equidistantly arranged on the left and right, and the two adjacent elastic strips 5 are preferably coaxially arranged. In fact, the equidistantly arranged connecting vertical bars 8 can ensure that the air holes are evenly distributed, avoid the air holes being too dense or sparse in some areas, and help the air to flow evenly in the jacket, thereby improving the overall breathability; at the same time, the coaxially arranged elastic strips 5 can better maintain elasticity, ensure that the shape and size of the air holes can remain stable during the stretching and rebound process, help maintain the elasticity and breathability of the breathable jacket 4, and improve the wearing comfort of the elastic waist 3. Furthermore, the outer layer of the breathable jacket 4 is preferably provided with a plurality of connecting portions 10 that are fixedly connected to the plurality of connecting vertical bars 8 in a one-to-one correspondence. In fact, the connecting portion 10 can be fixed to the connecting vertical bars 8 by gluing or sewing, so that the plurality of connecting vertical bars 8 play a role in supporting the breathable jacket 4 and prevent the plurality of elastic strips from being deformed and entangled in the breathable jacket 4.

[0034] It should be noted that the left and right outer portions of the breathable jacket 4 at the upper edge of the base layer 1 are preferably provided with openings 11 for the elastic strip 5 to extend through. The two first adhesive portions 6 are fixedly connected to the ends of the elastic strip 5, and the left and right outer portions of the breathable jacket 4 at the lower edge of the base layer 1 are fixedly connected to the two second adhesive portions 7 and the left and right portions of the elastic strip 5. In fact, the provision of these openings 11 provides a clear entry and exit path for the elastic strip 5, shifting the tension of the elastic strip 5 to the outside of the breathable jacket 4, dispersing the stress originally concentrated inside the breathable jacket 4, and achieving more even material distribution, preventing excessive compression and folding of the elastic strip 5 inside the breathable jacket 4, thereby effectively reducing wrinkles. In addition, the left and right outer portions of the breathable jacket 4 at the lower edge are fixedly connected to the two second adhesive portions 7 and the left and right portions of the elastic strip 5, respectively. This ensures more uniform deformation of the elastic waistband 3 at the lower edge, and provides a more secure attachment effect when the first adhesive portions 6 and second adhesive portions 7 are connected.

[0035] Specifically, the outer side of the elastic strip 5 is preferably provided with a plurality of semicircular raised dots 12. In practice, even if the inner and outer sides of the elastic waistband 3 may differ in appearance, they can be difficult to quickly distinguish by touch, potentially leading the user to mistakenly wear the belt with the inside facing out. The elastic waistband in the embodiment of the present invention is provided with semicircular raised dots 12. Due to their regular shape and distinct tactile feel, the user can quickly identify the inside and outside of the belt even without visual assistance. The dots provide clear tactile feedback when touched, allowing the user to quickly determine the inside and outside of the belt with a simple touch, thus avoiding confusion. By providing the semicircular raised dots 12 on the outer side of the elastic strip 5, the user can quickly confirm the inside and outside of the belt by touch when wearing it, ensuring the correct fit. This design is particularly suitable for belts that require frequent adjustments or are used in low-light environments, significantly improving the user experience. More specifically, luminous yarn 13 is sewn on the outer side of the breathable jacket 4 corresponding to the semicircular convex point 12. The luminous yarn 13 emits a weak light for naked eye identification in a relatively dark environment, so that the user can quickly identify the inside and outside of the elastic waist 3 and the position of the semicircular convex point 12.

[0036] Furthermore, the base layer 1 is preferably provided with a pressure-sensitive paper 14 in close contact with the core 2, and the portion of the base layer 1 corresponding to the pressure-sensitive paper 14 is a transparent gauze. In practice, when the core 2 in the base layer 1 absorbs a certain amount of urine, it collides and squeezes the pressure-sensitive paper 14 (the outer design of the base layer 1 makes the core 2 mainly expand inward and outward). The color developer in the inner layer of the pressure-sensitive paper 14 comes into contact with the colorant in the outer layer, causing a chemical reaction, thereby producing color. In practice, the portion of the base layer 1 corresponding to the pressure-sensitive paper 14 can be made of a polyethylene film, a polypropylene non-woven fabric, etc., which can serve as the outermost material of the breathable jacket 4 and provide a certain degree of transparency, allowing the user or other people to observe the color change of the pressure-sensitive paper 14 through the transparent gauze, so as to judge the expansion degree of the core 2 in the base layer 1 and estimate the user's urination situation.

[0037] The above are only specific embodiments of the present invention, which are described in detail. The relevant descriptions are only used to help understand the core idea of ​​the present invention, and do not limit the patent scope of the present invention. At the same time, for those skilled in the art, based on the idea of ​​the present invention, equivalent structures or equivalent process changes made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
