Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products, and in particular to a diaper with soft leak-proof side panels. Background Technology

[0002] Currently, diaper products on the market are mainly divided into two types in terms of side panel design: outward-folding and non-outward-folding. The side panel layers are generally single or double. In the most basic products, the elastic band of the side panel is wrapped between two layers of non-woven fabric. However, this structure has significant shortcomings: after wrapping the elastic band, the non-woven fabric of the side panel is not further laminated with other soft materials. Furthermore, the non-woven fabric used has a low basis weight or poor material feel. Therefore, when touching the side panel, the presence of the elastic band is clearly felt, resulting in a stiff overall feel and a noticeable elastic band sensation. This makes it easy for a baby's delicate skin to become red, allergic, or even experience minor abrasions when in contact or rubbing against the side panel, directly affecting the comfort of wearing the diaper and reducing consumer satisfaction. In addition, the insufficient liquid barrier performance of single-layer side panels is also a common problem; their leak-proof effect is weak and cannot effectively meet consumers' needs for efficient absorption and all-round protection in diapers. Utility Model Content

[0003] The main purpose of this invention is to overcome the shortcomings of the prior art and provide a diaper with soft, leak-proof side panels.

[0004] The present invention adopts the following technical solution:

[0005] A diaper with soft leak-proof side panels includes a body having a longitudinal direction in the length direction and a transverse direction in the width direction. The body includes a liquid-permeable top layer, an absorbent portion, and a liquid-impermeable bottom layer. The liquid-permeable top layer has longitudinally extending leak-proof side panels symmetrically arranged on the skin side. The leak-proof side panels are characterized by comprising a leak-proof side panel nonwoven fabric and a soft nonwoven fabric. The leak-proof side panel nonwoven fabric has a first surface and a second surface. The leak-proof side panel nonwoven fabric includes an elasticated portion and a non-elasticated portion. The soft nonwoven fabric is laminated to the first surface of the elasticated portion of the leak-proof side panel nonwoven fabric, and the softness of the soft nonwoven fabric is superior to that of the leak-proof side panel nonwoven fabric.

[0006] Specifically, the soft nonwoven fabric extends from the first surface of the rubber root portion of the leak-proof side-blocking nonwoven fabric to the second surface of the rubber root portion.

[0007] Specifically, the soft nonwoven fabric extends from the surface of the rubber root portion of the leak-proof side nonwoven fabric to the surface of the non-rubber root portion.

[0008] Specifically, the leak-proof nonwoven fabric and the liquid-permeable surface layer are connected by the bonding area, the soft nonwoven fabric has a first edge end, and the bonding area is located on the outer side in the lateral direction of the first edge end of the soft nonwoven fabric.

[0009] Specifically, the shortest lateral distance between the bonding area and the first edge end is greater than 5 mm.

[0010] Specifically, the soft nonwoven fabric is laminated in the middle region of the leak-proof partition within the elastic stretching range of the elastic rubber of the leak-proof partition, and the length of the soft nonwoven fabric in the longitudinal direction in the unfolded state of the main body is more than 50% of the total length of the leak-proof partition in the longitudinal direction.

[0011] Specifically, the soft nonwoven fabric is made of colorless or colored materials.

[0012] Specifically, the soft nonwoven fabric has a rectangular or wavy shape.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By laminating a layer of soft nonwoven fabric onto the leak-proof side panel, the soft nonwoven fabric covers the elastic band, improving the overall softness of the leak-proof side panel. At the same time, it forms a multi-layer material protection, improving the liquid barrier ability and reducing the risk of leakage. The soft nonwoven fabric can be made of colored materials or in different shapes, improving the overall aesthetics of the side panel and enhancing consumer perception. Adding unwinding, glue gun, slitting, and folding mechanisms for the side panel composite material to diaper equipment requires minimal equipment modification, is highly feasible, and practical.

Detailed Implementation

[0023] The present invention will be further described below through specific embodiments. Example

[0024] like Figure 1-3 As shown, a diaper with soft leak-proof side panels includes a body 1, which has a longitudinal direction in the length direction and a transverse direction in the width direction. The body 1 includes a liquid-permeable surface layer 2, an absorbent portion 3, and a liquid-impermeable bottom layer 4. The skin side of the liquid-permeable surface layer 4 is symmetrically provided with longitudinally extending leak-proof side panels 5. The leak-proof side panels 5 include a leak-proof side panel non-woven fabric 51 and a soft non-woven fabric 52. The leak-proof side panel non-woven fabric 51 includes an elasticated portion 511 with elastic bands and a non-elasticated portion 512. The leak-proof side panel non-woven fabric 51 has first surfaces 511a, 512a and second surfaces 511b, 512b. The first surfaces 511a, 512a of the leak-proof side panel non-woven fabric 51 are in contact with the skin side of the liquid-permeable surface layer in a planar unfolded state and in contact with the wearer's skin in the correct usage state. The opposite surface is the second surface 511b, 512b of the leak-proof side panel non-woven fabric 51.

[0025] A soft nonwoven fabric 52 is laminated to the first surface at the rubber root 511, and the softness of the soft nonwoven fabric is superior to that of the leak-proof side-blocking nonwoven fabric. Specifically, under specified conditions, when a plate-shaped probe presses the sample into a selected slit to a certain depth (approximately 8 mm), the maximum vector sum of the sample's own bending resistance and the frictional force between the sample and the slit is called softness, denoted by gram. The smaller the softness value, the softer the sample. A softness meter is typically used to test the softness of nonwoven forming materials. In this embodiment, the softness value of the soft nonwoven fabric is less than that of the leak-proof side-blocking nonwoven fabric; that is, the softness of the soft nonwoven fabric is greater than that of the leak-proof side-blocking nonwoven fabric.

[0026] In this embodiment, the soft nonwoven fabric 52 is a water-repellent hot air nonwoven fabric.

[0027] Furthermore, the soft nonwoven fabric 52 extends from the first surface 511a of the elastic root portion 511 of the leak-proof side-blocking nonwoven fabric 51 to the second surface 511b of the elastic root portion 511, that is, the soft nonwoven fabric 52 is laminated at the second surface 511b of the elastic root portion 511.

[0028] Furthermore, the soft nonwoven fabric 52 extends from the surfaces 511a and 511b of the elastic root portion 511 of the leak-proof side-blocking nonwoven fabric 51 to the surfaces 512a and 512b of the non-elastic root portion 512, that is, the soft nonwoven fabric 52 is laminated to the first surface 512a and / or the second surface 512b of the non-elastic root portion 512. In this embodiment, the first edge end 520 of the soft nonwoven fabric 52 extends to the non-elastic root portion 512, such that the soft nonwoven fabric 52 folds over and covers the surfaces 511a and 511b of the elastic root portion and part of the surfaces 512a and 512b of the non-elastic root portion, increasing the area of ​​the soft nonwoven fabric 52 covering the surface of the leak-proof side-blocking nonwoven fabric 51.

[0029] By laminating a layer of soft nonwoven fabric onto the leak-proof barrier nonwoven fabric, the soft nonwoven fabric covers the rubber root, improving the overall softness of the leak-proof barrier. At the same time, it forms a multi-layer material protection, improving the liquid barrier ability and reducing the risk of urine leakage.

[0030] Specifically, the leak-proof nonwoven fabric 51 and the liquid-permeable surface layer 2 are connected by an adhesive area 6. The soft nonwoven fabric 52 has a first edge end 520, and the adhesive area 6 is located on the outer side in the lateral direction beyond the first edge end 520. In this embodiment, the shortest lateral distance between the adhesive area 6 and the first edge end 520 is greater than 5 mm.

[0031] Specifically, the soft nonwoven fabric 52 is laminated in the middle area of ​​the leak-proof partition 5 within the elastic stretch range of the elastic rubber of the leak-proof partition 5. When the body is unfolded, the length of the soft nonwoven fabric 52 in the longitudinal direction is more than 50% of the total length of the leak-proof partition 5 in the longitudinal direction.

[0032] Specifically, the soft nonwoven fabric 52 is made of a colorless or colored material. The soft nonwoven fabric 52 has a rectangular or wavy shape. In this embodiment, the soft nonwoven fabric 52 is rectangular. The soft nonwoven fabric 52 can be made of colored material or use different shapes, improving the overall aesthetics of the side panel and enhancing consumer perception.

[0033] like Figure 5 , 6 The image shows two manufacturing processes for the leak-proof side panels of a diaper.

[0034] like Figure 5 As shown, the manufacturing process steps for the leak-proof partition in Example 1 are as follows:

[0035] Leak-proof edge-separating non-woven fabric 51 and soft non-woven fabric 52 are centrally laminated to form an edge-separating semi-finished product;

[0036] Cut the semi-finished product along the side;

[0037] After the elastic rubber 513 is applied to the leak-proof non-woven fabric, the opening is sealed and the rubber is folded and wrapped to form the leak-proof side 5.

[0038] The leak-proof partition 5 is symmetrically laminated onto the impermeable bottom layer on both sides of the absorbent core.

[0039] like Figure 6 As shown, another manufacturing process step for the leak-proof partition in Example 1 is as follows:

[0040] After the elastic rubber 513 is unwound, stretched, and glued onto the leak-proof non-woven fabric, the leak-proof non-woven fabric 51 is sealed and glued and then folded to wrap the rubber.

[0041] Soft nonwoven fabric is unwound in 52 rolls, sizing is applied, and then slit.

[0042] After the soft nonwoven fabric 52 is conveyed and combined with the leak-proof partition nonwoven fabric 51, the edge of the soft nonwoven fabric is folded outward to cover the elastic rubber area on both sides, and then the front and rear ends are sealed with adhesive to form a leak-proof partition.

[0043] The leak-proof partition 4 is symmetrically laminated onto the impermeable bottom layer on both sides of the absorbent core.

[0044] In production, adding unwinding, glue gun, slitting and folding mechanisms for the side-part composite material to diaper equipment requires minimal equipment modifications, is highly feasible, and is very practical. Example

[0045] like Figure 4 As shown, the difference between the second embodiment and the first embodiment is that the soft nonwoven fabric 52 has a wavy shape, which improves the overall aesthetics of the side panel.

[0046] The above are only a few specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
