Description

A kind of paper diaper with flexible cushioning leak barrier

technical field

The invention relates to the technical field of diaper manufacturing, in particular to a diaper with a flexible buffer leak barrier.

Background technique

The user groups of diapers mainly include babies and adults. Among them, the Chinese market is mainly baby diapers. Nearly 20 million babies are born in China every year, and the number of babies aged 0 to 2 who use diapers has reached more than 40 million, which shows that it has a huge market. It has been more than half a century since the birth of diapers. During this period, it has undergone many technical improvements, but it can be found that the focus of its many improvements is how to improve the performance of the core, focusing on absorption speed, anti-reverse seepage, The thickness and strength and toughness have been improved, but there are not many modifications to the specific structure of diapers.

The leakage barrier of traditional diapers is shown in Figure 1. It is composed of a piece of waterproof non-woven fabric (a) and at least one high-elastic elastic band (b). The high-elastic elastic band (b) is combined with waterproof non-woven fabric ( a) The inner side at the crease of the half fold. Due to the small diameter of the high-elastic elastic band (b), the composite leak is usually in line contact with the baby's skin, and it is easy to scratch the skin after long-term use.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a diaper with a flexible buffer leak barrier, which changes the shape of the traditional leak barrier so that it is not easy to cause damage to the baby's delicate skin.

The technical scheme that the present invention solves technical problem is as follows:

A paper diaper with a flexible buffer leak barrier, comprising a waterproof bottom layer, a core body located in the middle of the waterproof bottom layer, flexible buffer leak barriers arranged on both sides of the core body and fixedly connected with the waterproof bottom layer, the flexible buffer leak barrier includes waterproof nonwoven Cloth and high-elastic elastic, the waterproof non-woven fabric has an outer side and an inner side, the waterproof non-woven fabric is folded inwardly, the high-elastic elastic band is compounded on the inner side of the waterproof non-woven fabric, and the waterproof non-woven fabric and The contact points of the high-elastic elastic are respectively the first contact point and the second contact point, and the waterproof non-woven fabric between the first contact point and the second contact point is a buffer section, and the buffer section and the high-elastic elastic jointly enclose A cylindrical buffer zone.

Further, the buffer area is composed of at least two sub-areas, and each sub-area is formed by inflecting and enclosing a local buffer section.

Further, the buffer area is filled with flexible supports.

Further, the flexible support is silica gel, sponge or foam material.

The diapers with flexible buffer leak barriers disclosed by the present invention change the shape of traditional leak barriers, increase the contact surface with the baby's skin, and effectively prevent the baby's tender skin from being scratched by the diaper. The invention can be used in the production of paper diapers.

detailed description

The idea, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts belong to The protection scope of the present invention. In addition, all the connection/connection relationships mentioned in this article do not refer to the direct connection of components, but mean that a better connection structure can be formed by adding or reducing connection accessories according to specific implementation conditions. The various technical features in the invention can be combined interactively on the premise of not conflicting with each other.

Embodiment 1, as shown in Figure 2, a paper diaper with a flexible buffer leak barrier, comprising a waterproof bottom layer, a core body located in the middle of the waterproof bottom layer, flexible buffer leak barriers arranged on both sides of the core body and fixedly connected to the waterproof bottom layer, The flexible buffer leak barrier includes a waterproof non-woven fabric and a high-elastic elastic band 1. The waterproof non-woven fabric has an outer side and an inner side. On the inner side of the non-woven fabric, the contact points between the waterproof non-woven fabric and the high elastic elastic band 1 are the first contact point and the second contact point respectively, and the waterproof non-woven fabric between the first contact point and the second contact point is a buffer Segment 21 , the buffer segment 21 together with the high-elastic rubber band 1 encloses a cylindrical buffer area 22 . The cushioning area 22 is hollow, and when the diaper is in use, it will become a flat cloth film under pressure, which can increase the contact area between the leak barrier and the baby's skin to a certain extent.

Example 2, as shown in Figure 3, a diaper with a flexible buffer leak barrier, its overall structure is similar to that of Example 1, the difference is that the flexible buffer leak barrier includes waterproof non-woven fabric and high elastic elastic band 1, The waterproof non-woven fabric has an outer side and an inner side, the waterproof non-woven fabric is folded inwardly, the high elastic elastic band 1 is compounded on the inner side of the waterproof non-woven fabric, the waterproof non-woven fabric and the high elastic elastic band 1 The contact points are respectively the first contact point and the second contact point, and the waterproof non-woven fabric between the first contact point and the second contact point is the buffer section 21, and the buffer section 21 and the high-elastic elastic band 1 together enclose a long cylinder Shaped buffer area 22 . The buffer area 22 is composed of at least two sub-areas, and each sub-area is formed by bending and enclosing a local buffer section 21 . The buffer section 21 is folded multiple times to form a shape similar to waves, and each trough is heat-pressed and shaped, so that the top of the leak-proof leak is formed into several sub-regions, which effectively prevents the buffer region 22 from being deformed due to lateral pressure. Skew failure.

Example 3, as shown in Figure 4, a diaper with a flexible buffer leak barrier, its overall structure is similar to that of Example 1, the difference is that the flexible buffer leak barrier includes waterproof non-woven fabric and high elastic elastic band 1, The waterproof non-woven fabric has an outer side and an inner side, the waterproof non-woven fabric is folded inwardly, the high elastic elastic band 1 is compounded on the inner side of the waterproof non-woven fabric, the waterproof non-woven fabric and the high elastic elastic band 1 The contact points are respectively the first contact point and the second contact point, and the waterproof non-woven fabric between the first contact point and the second contact point is the buffer section 21, and the buffer section 21 and the high-elastic elastic band 1 together enclose a long cylinder Shaped buffer area 22 . The cushioning area 22 is filled with flexible supports. The flexible support is silica gel, sponge or foam material. Fill the cushioning area 22 described in Example 1 or the sub-area described in Example 2 with silica gel, sponge or foam material, so that the flexible buffer leak barrier can be supported to a certain extent even when it is under pressure, effectively increasing the leak barrier Contact area with baby's skin.

The preferred embodiments of the present invention have been described in detail above, but the invention is not limited to the described embodiments, and those skilled in the art can also make various equivalent modifications or replacements without violating the spirit of the present invention.
