Abstract

A paper diaper with front and back leak-proof three-dimensional shield comprises a hydrophilic surface layer (1), a waterproof bottom layer, and a water-absorbing cotton core layer (2) arranged therebetween. The two lateral sides of the paper diaper are respectively provided with a lateral leak-proof three-dimensional shield (3), in which elastic bands (5) capable of longitudinally shrinking are arranged. The two longitudinal ends of the three-dimensional shield (3) are stuck with the hydrophilic surface layer (1) at the outside of the two longitudinal ends of the water-absorbing cotton core layer (2). Preferably, the shrinking length of the elastic bands (5) is greater than the longitudinal length of the water-absorbing cotton core layer (2).When the paper diaper is used, the elastic bands (5) are stretched to lift the waterproof bottom layer to form a certain height, thus the front end and the back end of the paper diaper generate good leak-proof effect. In addition, a water-absorbing layer (6) additionally arranged on the longitudinal ends of the water-absorbing cotton core layer (2) can realize more obvious leak-proof effect. An elastic waistband (7) is adhered on the back surface of the waterproof bottom layer to ensure more comfortable and close-fitting to wear.

具体实施方式 detailed description
参见图 2, 本发明包括亲水面层 1、 防水底层， 在亲水面层与防水底层之间是吸水 棉芯层 2 (图中的虚线部分）， 在吸水棉芯层纵向两端外侧， 亲水面层与防水底层粘合在 一起， 在纸尿裤两侧各设有一防止侧漏的立体护围 3， 立体护围 3内装有可纵向收縮的 的橡筋 5， 立体护围纵向两端与亲水面层粘合， 粘合位置处于吸水棉芯层纵向两端的外 侧， 即图 2中阴影部分 B表示的区域。 这样的结构， 可使纸尿裤穿着时纵向端形成一定 高度， 不但侧向的立体护围可以防止尿液从侧边漏出， 纵向端也可以防止尿液从前后漏 出。如果将立体护围内橡筋的收縮长度（即图 2中的 L2 )设计成大于吸水棉芯层的纵向 长度， 让橡筋拉伸时可以直接提起防水底层； 并且， 立体护围纵向两端与亲水面层粘合 的位置与橡筋的收縮起始端最好有重合，均可处于吸水棉芯层纵向两端外侧 0. 8-1. 5cm 处， 则防漏效果更好。 而传统纸尿裤橡筋的收縮长度（参见图 1中的 L1 )是小于吸水棉 芯层的纵向长度的。  Referring to FIG. 2, the present invention comprises a hydrophilic surface layer 1 and a waterproof bottom layer. Between the hydrophilic surface layer and the waterproof bottom layer is a water absorbing cotton core layer 2 (broken line portion in the drawing), outside the longitudinal ends of the absorbent cotton core layer. The hydrophilic surface layer is bonded to the waterproof bottom layer, and each side of the diaper is provided with a three-dimensional protection 3 for preventing side leakage, and the three-dimensional protection 3 is provided with an elastic band 5 which can be longitudinally contracted, and the longitudinal ends of the three-dimensional protection circumference are The hydrophilic surface layer is bonded, and the bonding position is on the outer side of the longitudinal ends of the absorbent core layer, that is, the area indicated by the shaded portion B in Fig. 2. Such a structure allows the diaper to be formed with a certain height when the longitudinal end is worn, and not only the lateral three-dimensional guard can prevent urine from leaking from the side, but also the longitudinal end can prevent urine from leaking from the front and the back. If the contraction length of the inner rubber band (ie, L2 in FIG. 2) is designed to be larger than the longitudinal length of the absorbent cotton core layer, the waterproof bottom layer can be directly lifted when the rubber band is stretched; and The adhesion to the hydrophilic surface layer is preferably coincident with the contraction starting end of the elastic rib, and may be located at the outer side of the longitudinal ends of the absorbent cotton core layer at a height of 0.8-1. 5 cm, so that the leakage prevention effect is better. The contraction length of the conventional diaper elastic (see L1 in Fig. 1) is smaller than the longitudinal length of the absorbent core.
为了让纸尿裤的防漏效果更好， 可在上述结构的基础上， 如图 3所示， 在纸尿裤的 吸水棉芯层 2的纵向端加装一片吸水层 6， 该片吸水层 6直接粘贴于两侧边立体护围及 亲水面层上面， 且纵向两端可同时加装。 也可在纸尿裤的纵向端装配弹性腰围 7， 弹性 腰围直接粘贴在防水底层上 （即纸尿裤的背面）， 同样， 纵向两端可同时加装。 弹性腰 围加装在背面， 可使穿戴更加舒适、 贴身。 上述加装的吸水层 6及背面的弹性腰围 7， 既可单独实施， 也可同时实施。  In order to make the leakage prevention effect of the diaper better, on the basis of the above structure, as shown in FIG. 3, a water absorbing layer 6 is attached to the longitudinal end of the absorbent cotton core layer 2 of the diaper, and the water absorbing layer 6 is directly pasted on the absorbing layer. Both sides of the three-dimensional protection and hydrophilic surface layer, and the longitudinal ends can be installed at the same time. An elastic waistband can also be attached to the longitudinal end of the diaper. The elastic waistline is directly attached to the waterproof bottom layer (ie, the back of the diaper). Similarly, the longitudinal ends can be attached at the same time. The elastic waist is attached to the back for a more comfortable fit and fit. The above-mentioned water absorbing layer 6 and the elastic waist 7 on the back side may be implemented separately or simultaneously.
