[0002] The absorbent core of wearable absorbent article is usually compounded between two layers of non-woven fabric, one of which is water-repellent and the other is hydrophilic, in the case of no special treatment, the three layers of material are connected in one body in the form of close compounding to ensure that the structural strength meets the use requirements, and the absorbed liquid will not leak out when used correctly, avoiding unnecessary trouble, but the absorbent article processed by this process is generally not very soft, and the foreign body sensation is more obvious when worn.
[0003] With the continuous progress of technology and the improvement of comprehensive consumption level, it is the basic direction of new product development to improve the wearing performance of absorbent article and improve the soft and comfortable performance of absorbent article as much as possible under the premise of meeting the absorption requirements. In addition to using softer fabric as raw material, adjusting and optimizing the compounding process, improving the structural strength while reducing the interference of the compounding structure on the overall softness is also a feasible process route. Therefore, in consideration of the requirements of absorption performance and product comfort and stability, a suspension core paper diaper appears, which tightly compounds the edges of the outer non-woven fabric, and only connects the edges of the inner absorbent core to the outer non-woven fabric, so that an inner pocket appears between the absorbent core and the outer non-woven fabric, improving the liquid containing capacity of the absorbent product, and also ensuring the softness.
[0004] However, due to the above-mentioned scheme, the suspension core structure is still in the initial stage, and there are still some problems, the most obvious of which is that the existence of the inner pocket space makes the absorbent article prone to inside-outside layering when worn, the liquid has a high degree of freedom before being absorbed by the absorbent core, and may escape from the hydrophilic non-woven fabric side due to the user's body movement, causing leakage problems. From the whole wearing process, this experience is not very good, so improving the negative impact of the inner pocket structure on the stability of the absorbent product is one of the improvement directions.

DETAILED DESCRIPTION
[0022] The embodiments of the present application will be described below in conjunction with the accompanying drawings and related embodiments, and the embodiments of the present application are not limited to the following embodiments, and the present application relates to the necessary components in the related technical field, which should be regarded as the known technology in the technical field, and can be known and mastered by the skilled in the art.
[0023] In conjunction with Figures 1 to 4 As shown in the drawings, the reference basis of the Length Direction length direction and the Width Direction width direction is determined by the length and width trend of the absorbent article in the flat state, and the corresponding to the absorbent core 2 or the absorbent body A is also determined by its orientation relative to the absorbent article described above, specifically, the present application discloses a paper diaper with a multi-inner pocket suspended core, comprising an absorbent body A composed of a bottom layer 1, an absorbent core 2 and a surface layer 3 connected in sequence, the two ends of the absorbent core 2 in the length direction are connected with the bottom layer 1 and / or the surface layer 3.
[0024] The absorbent core 2 and the bottom layer 1 are separated from each other, so that a suspended inner pocket 4 is formed between them when the absorbent body A is in a curved state; not less than two additional absorbent cores 5 are further provided between the absorbent core 2 and the bottom layer 1, the edges of the additional absorbent core 5 are connected with the absorbent core 2, and a small inner pocket 6 is formed between the absorbent core 2 and the additional absorbent core 5.
[0025] The scheme is further improved based on the original suspension core body diaper route, considering that the existing suspension core body diaper mentioned in the background art improves the absorption and dispersion efficiency of urine to a certain extent, but the increased weight of the core body easily leads to reduced adhesion of the diaper to the baby's skin, and the bottom of the suspension core body is completely free from the bottom layer, and when the liquid seeps between the core body and the bottom layer, some negative effects may be caused by the rapid flow, especially in the case of large baby activity or long-term wearing, the risk of urine side leakage and back leakage will increase accordingly, which affects the use effect to a certain extent.
[0026] In order to overcome this defect while retaining the advantages of the original suspension core body design, the additional absorption core 5 is added below the original suspension core body structure, which not only directly improves the overall absorption capacity of the diaper, but also utilizes the additional small inner pockets 6 space formed between the additional absorption core 5 and the absorption core 2, which can better maintain the adhesion of the diaper to the baby's skin after absorbing urine, and the liquid will not flow completely unimpeded when it seeps between the absorption core 2 and the bottom layer 1, and the free liquid will be retained by the small inner pockets 6 and absorbed by the additional absorption core 5 in the case of frequent human activity, thus compared with the prior scheme, the urine side leakage and back leakage problem is improved.
[0027] And the setting of the small inner pockets 6 also plays a role in dispersing urine, avoiding the thick and uncomfortable feeling caused by the local accumulation of urine in the absorption core 2, further, the structure composed of the small inner pockets 6 is the absorption core 2 and the additional absorption core 5, both of which are water-absorbing substances, so that the urine can be quickly absorbed and dispersed in this space, making the wearing experience of the diaper more comfortable and dry, and the additional absorption core 5 can quickly absorb and lock the urine, reducing the possibility of urine backflow and side leakage. At the same time, the connection design between the additional absorption core 5 and the absorption core 2 enables the small inner pockets 6 to fully play their buffering and storage role, so that the diaper can still maintain good shape and stability even after absorbing a large amount of liquid.
[0028] In the curved state of the absorption body A, the suspension inner pocket 4 flexibly adjusts its shape with the deformation of the bottom layer 1 and the surface layer 3, ensuring that the distribution of liquid around the absorption core 2 is more uniform, and cooperating with the auxiliary absorption function of the small inner pockets 6, not only improves the liquid absorption efficiency of the diaper, but also enhances the overall comfort and adhesion, and the above-mentioned scheme improves the liquid absorption capacity, comfort and adhesion of the diaper by reasonably setting the suspension inner pocket 4, the additional absorption core 5 and the small inner pockets 6, etc., and brings a better wearing experience to the user.
[0029] As a preferred embodiment one of the utility model, the additional absorption core 5 is any one of small white paper, fluffy cotton, water-absorbing fiber layer, SAP composite layer, wherein, like Figure 5As shown, when the additional absorbent core 5 is a SAP composite layer, it is composed of a cladding layer 50 and SAP polymer particles 51 wrapped in the cladding layer 50. Since the additional absorbent core 5 is not the main absorbent material, the absorption capacity of the diaper itself is determined by the absorbent core 2. Therefore, as long as the material with the ability to absorb or control moisture is used as a single layer, and it can be connected to the absorbent core 2 to form a small pocket 6, but if the size of the diaper is large enough, the space of the floating pocket 4 can meet the setting of a small absorbent with SAP polymer particles 51. In this case, the SAP composite layer can also be an optional specification of the additional absorbent core 5.
[0030] In combination Figure 1 With Figure 2 As shown, as a preferred embodiment two of the present application and its further improvement, the length of the additional absorbent core 5 in the length direction of the absorbent body A is ≤ the length of the additional absorbent core 5 in the width direction of the absorbent body A; and as a further improvement of the above technical solution, the additional absorbent core 5 is arranged along the length direction of the absorbent core 2, and the additional absorbent core 5 is at least two edges combined with the absorbent core 2.
[0031] The above technical solution is shown in combination with the drawings. In this scheme, the additional absorbent core 5 is arranged along the length direction of the absorbent body A, and from the shape, it is approximately rectangular or square. Therefore, in order to better form a small pocket 6, at least two edges combined with the absorbent core 2 can form a relatively stable connection structure, and the shape of the small pocket 6 will be relatively easy to maintain. In this scheme, the number of additional absorbent cores 5 is two or more. More additional absorbent cores 5 will form more small pockets 6. Whether several additional absorbent cores 5 form one small pocket 6 together or are independent of each other, they can play a role in avoiding problems caused by excessive liquid flow in actual application, and reasonably control the liquid in the floating pocket 4 to be fully absorbed.
[0032] In combination Figure 1 With Figure 3 As shown, as a preferred embodiment three of the present application and its further improvement, the length of the additional absorbent core 5 in the length direction of the absorbent body A is > the length of the additional absorbent core 5 in the width direction of the absorbent body A; and as a further improvement of the above technical solution, the additional absorbent core 5 is arranged along the width direction of the absorbent core 2, and the additional absorbent core 5 is at least two ends in the length direction combined with the absorbent core 2.
[0033] Compared with the previous scheme, the scheme is shown in the drawings, the additional absorbent core 5 is close to a strip as a whole, the length is not more than the length of the absorbent core 2, and the front and rear flow channels are formed between the additional absorbent core 5, but compared with the existing front and rear flow channel paper diaper, since the additional absorbent core 5 also adopts the mode of two end portions being combined with the absorbent core 2, the small inner pocket 6 is formed, therefore the liquid also has a certain transverse flow capacity, and after entering the small inner pocket 6, the liquid is also absorbed by the absorbent core 2 or the additional absorbent core 5, and the additional absorbent core 5 also has the ability to stabilize the shape of the paper diaper in the floating inner pocket 4.
[0034] In combination with the drawings, Figure 1 With Figure 4 As a preferred embodiment four of the utility model, the length of the additional absorbent core 5 in the length direction of the absorbent body A is less than or equal to the length of the additional absorbent core 5 in the width direction of the absorbent body A, and the length of the additional absorbent core 5 in the length direction of the absorbent body A is greater than the length of the additional absorbent core 5 in the width direction of the absorbent body A, and any piece of additional absorbent core 5 is combined with the absorbent core 2 at least at two edges.
[0035] The above technical scheme in combination with the drawings, the scheme is equivalent to the combination of the previous two schemes, and the additional absorbent core 5 with different shapes in the two schemes can be combined as needed between the absorbent core 2 and the bottom layer 1, so that the space between the additional absorbent core 5 can form a channel with certain flow guiding effect, and the small inner pocket 6 can also form a storage space with better containment capacity, which is similar to a complete inner pocket, and this combined space can exist in the required position, such as the front and rear ends of the paper diaper, to prevent front and rear leakage,
[0036] The utility model has the beneficial effect that:
[0037] The technical scheme further provides a plurality of small inner pockets 6 composed of water-absorbing substances in the floating inner pocket 4, which slightly reduces the flowability of the liquid in the floating inner pocket 4 at a small cost, and greatly improves the buffering and storage capacity of the floating inner pocket 4 for the liquid, and the additional absorbent core 5 also has the effect of increasing the absorption capacity, and after absorbing water, the absorbent article can also maintain the overall shape of the upright, and the problem of dislocation and deformation caused by the body movement of the user during wearing is not easy to occur, and the liquid is not easy to leak, so the user's whole wearing experience is obviously improved.
[0038] The above-mentioned is only the preferred embodiment of the utility model, it should be pointed out that, for ordinary technical personnel in the prior art, without departing from the principle of the utility model, a number of improvements and refinements can also be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
