TECHNICAL FIELD
[0001] The utility model relates to paper diaper technical field, concretely is a pleated super soft paper diaper. BACKGROUND
[0002] The paper diaper is disposable, and can be discarded after use. It is made of non-woven fabric, toilet paper, fluff pulp, high molecular water-absorbing resin, PE film, rubber band and other materials. The current market paper diaper adds spandex rubber band in the waist and hip part to fix. However, the spandex rubber band is prone to leave marks and imprints on the baby's waist and hip during use, and the poor air permeability brings an extremely uncomfortable experience to the baby.

[0003] The utility model discloses a pleated super soft paper diaper to solve the problem in the above background.
[0004] To achieve the above object, the utility model provides the following technical scheme:
[0005] A pleated super soft paper diaper, comprising a waist and a hip part, the waist comprises a first outer non-woven fabric, a second outer non-woven fabric, a first inner non-woven fabric and a second inner non-woven fabric, the first outer non-woven fabric and the first inner non-woven fabric are bonded with a waist rubber band, the second outer non-woven fabric is formed with an outer waist pleat, the second inner non-woven fabric is formed with an inner waist pleat, the outer waist pleat and the inner waist pleat are arranged alternately, and the pleat spacing of the outer waist pleat and the inner waist pleat is the same.
[0006] The hip part comprises a third inner non-woven fabric and a third outer non-woven fabric, the third inner non-woven fabric is formed with an inner hip pleat, and the third outer non-woven fabric is formed with an outer hip pleat.
[0007] In a possible implementation, the inner hip pleat and the outer hip pleat are positionally corresponding.
[0008] In a possible implementation, the pleat spacing of the outer waist pleat and the outer hip pleat is the same, and the pleat spacing of the inner waist pleat and the outer hip pleat is the same.
[0009] In a possible implementation, the outer waist pleat, the inner waist pleat, the outer hip pleat and the inner hip pleat are all prepared by ultrasonic welding process.
[0010] In a possible implementation, the second inner non-woven fabric, the second outer non-woven fabric, the third outer non-woven fabric and the third inner non-woven fabric adopt the same non-woven fabric.
[0011] In one possible implementation, the inner waist portion creases are aligned with the inner crotch portion creases, and the outer waist portion creases are aligned with the outer crotch portion creases.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] By setting the accordion creases on the inner and outer sides of the waist portion and the crotch portion, the air permeability between the diaper and the baby's skin is greatly improved. The inner and outer sides of the waist portion are both provided with two layers of non-woven fabric. The inner layer of non-woven fabric can effectively reduce the constriction of the baby caused by the spandex elastic band, and reduce the skin discomfort caused by the inflexibility of the spandex elastic band. The inner and outer creases are arranged alternately, which can further improve the comfort of the diaper and meet the needs of the baby's various postures. BRIEF DESCRIPTION OF DRAWINGS

[0017] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects of the utility model will be described in detail below in combination with the drawings and preferred embodiments.
[0018] As shown in Figs. 1-3 A pleated super-soft diaper includes a waist portion 1 and a crotch portion 2. The waist portion 1 includes a first outer non-woven fabric 11, a second outer non-woven fabric 14, a first inner non-woven fabric 12, and a second inner non-woven fabric 13. A waist elastic band 15 is bonded between the first outer non-woven fabric 11 and the first inner non-woven fabric 12. An outer waist portion crease 101 is formed on the second outer non-woven fabric 14, and an inner waist portion crease 102 is formed on the second inner non-woven fabric 13. The outer waist portion crease 101 and the inner waist portion crease 102 are arranged alternately, and the crease spacing of the outer waist portion crease 101 and the inner waist portion crease 102 is the same. The crotch portion 2 includes a third inner non-woven fabric 21 and a third outer non-woven fabric 22. An inner crotch portion crease 202 is formed on the third inner non-woven fabric 21, and an outer crotch portion crease 201 is formed on the third outer non-woven fabric 22.
[0019] In the utility model, two layers of non-woven fabrics are arranged on the inner and outer sides of the waist part, the non-woven fabric on the surface is used for carrying out wrinkle processing, and the non-woven fabric on the inner layer is used for being bonded and fixed with the elastic band. The two layers of non-woven fabrics can effectively reduce the skin constriction of the elastic band, and the organ-like wrinkle can increase the ventilation space and the air permeability of the diaper. And the organ-like wrinkle arranged on the inner and outer hip crotch parts can be cooperated with the organ-like wrinkle of the waist part, so that the ventilation space is further expanded.
[0020] Further, the inner hip crotch part wrinkle 202 and the outer hip crotch part wrinkle 201 are positionally corresponding. The wrinkle interval of the outer waist part wrinkle 101 and the outer hip crotch part wrinkle 201 is same; the wrinkle interval of the inner waist part wrinkle 102 and the outer hip crotch part wrinkle 202 is same. The inner waist part wrinkle 102 is aligned with the inner hip crotch part wrinkle 202, and the outer waist part wrinkle 101 is aligned with the outer hip crotch part wrinkle 201. The alignment can realize the continuity of the waist circumference and the hip crotch part wrinkle, and the whole appearance looks like a continuous whole. And the inner and outer wrinkle are arranged in an alternating manner, so that the wearing comfort of the diaper is further increased, and the needs of the baby's multiple body movements are adapted.
[0021] In order to facilitate processing, the second inner non-woven fabric 13, the second outer non-woven fabric 14, the third outer non-woven fabric 22 and the third inner non-woven fabric 21 adopt the same non-woven fabric. That is, a piece of non-woven fabric is divided into different areas to form the areas required for wrinkle processing of the inner and outer waist parts and the inner and outer hip crotch parts.
[0022] In the utility model, the outer waist part wrinkle 101, the inner waist part wrinkle 102, the outer hip crotch part wrinkle 201 and the inner hip crotch part wrinkle 202 are all prepared by ultrasonic welding process. The preparation process of the diaper of the utility model will be described as follows, as shown in the figure: Fig. 3
[0023] Firstly, the waist part elastic band 15 is arranged between the first outer non-woven fabric 11 and the first inner non-woven fabric, and is bonded by glue to form a first composite; then the first composite is bonded with the second outer non-woven fabric 14 by ultrasonic welding to form the outer waist part wrinkle; then the first composite is bonded with the second inner non-woven fabric by ultrasonic welding to form the inner waist part wrinkle and obtain a second composite; next, the third inner non-woven fabric, the third outer non-woven fabric and the hip crotch part elastic band 23 are bonded by ultrasonic welding to obtain a third composite, and the inner hip crotch part wrinkle and the outer hip crotch part wrinkle are formed; finally, the first composite and the third composite are bonded by ultrasonic welding, and the inner waist part wrinkle is formed. In the utility model, the waist part elastic band and the hip crotch part elastic band can be the same elastic band.
