Background technique

Diapers are a kind of sanitary products commonly used by babies. Generally speaking, diapers are composed of three main parts: surface cover layer, absorbent core layer and base fabric. Surface coatings may also be referred to as coatings. The cover fits snugly against the baby's body, which promotes quick penetration of urine and effectively prevents rewet, keeping the surface of the diaper dry. At present, the covering layer of diapers in the domestic market is basically a non-woven surface layer. The breathable non-woven fabric can improve the air permeability inside the diaper, and the water vapor can circulate outside the diaper, and the moisture and heat can be discharged in time, effectively reducing the air permeability of the diaper. The chance of diaper rash, soft and comfortable without irritating the skin. The absorbent core may also be referred to as an absorbent core. The main function of the absorbent core layer is to capture and quickly absorb urine, disperse urine or spread it throughout the core layer through capillary action, and finally absorb and store urine. At present, the absorbent core layer of diapers in the domestic market is mainly a layered structure composed of pure wood pulp (fluff pulp) and super absorbent resin (SAP). The base fabric, the outermost structure of the diaper, is impermeable and prevents the moisture in the absorbent core from seeping out. Many foreign diaper base fabrics have used more comfortable non-woven fabrics, but due to the high price, the diaper base fabrics in the domestic market are still mainly composed of PE films.

According to a number of studies at home and abroad, the temperature of the skin covered by diapers is 1 to 2 degrees higher than that of the bare skin. The internal temperature of the diaper is too high, which will make the baby boy's testicles in a high temperature state. In addition, the absorbent core layer of diapers is usually a rectangular sheet structure. When in use, the sheet-shaped absorbent core layer is naturally bent and covers the baby boy's scrotum, and the testicles are close to the baby's body, so that the scrotum cannot naturally sag away from the body to cool down. , is not conducive to the normal heat dissipation of the testis, will affect the normal growth and development of the testis, and have long-term adverse effects.

Detailed ways

In FIG. 1 , the front end of the absorbent core layer 10 has branch structures 13 and 15 . Between the two branches 13 and 15 there is an opening whose included angle is not 0 degrees. The branch 13, the branch 15 and the main body of the absorbent core layer have a Y-shaped structure. The branches 13 and 15 are integrated with the main body of the absorbent core layer. The absorbent core layer 10 is obtained by cutting from the same absorbent core layer base material. There is a process hole 18 at the branch starting point of the branch 13 and the branch 15 . The process hole 18 may be circular, or other shapes such as rhombus and rectangle. Setting the process hole can prevent the material from accumulating at the junction of the branches 13 and 15 when the branches 13 and 15 are folded, making it difficult to fold. The absorbent core layer can be made of the same material, or it can be composed of several absorbent materials of different materials.

In Fig. 2, the two branches 13 and 15 of the absorbent core layer 10 are folded upwards along their respective roots, and the adjacent edges of the branches 13 and 15 are joined together. In this way, the branches 13 and 15 of the absorbent core layer 10 are combined at the front end of the absorbent core layer 10 to form a three-dimensional conical liquid-absorbent structure. The combination of branch 13 and branch 15 is folding and assembling. The root where branch 13 and branch 15 are connected is the apex of the pyramidal three-dimensional structure. The three-dimensional tapered structure formed by the combination of the branch 13 and the branch 15 encloses a tapered space. This tapered space provides extra space for a baby boy's scrotum.

In Fig. 3, the side shape of the absorbent core layer 1 in the conventional diaper is U-shaped in the state of use. The absorbent core layer of the existing diaper is an integral elongated structure, and the unfolded plane shape is rectangular or oblong. In the state of use, the absorbent core layer 1 of the existing diaper is U-shaped. The absorbent core layer 10 of the diaper of the present invention is in use, and a plurality of branches are combined to form a three-dimensional structure 3 at the front end of the absorbent core layer 10 . When there are two branches, the combined three-dimensional structure 3 is a three-dimensional pyramid structure. The branch starting point of the two branches is the top of the three-dimensional structure 3 . When there are multiple branches, the three-dimensional structure formed by combination is a three-dimensional structure with multiple vertices. The three-dimensional structure 3 forms a three-dimensional space, which can accommodate the genitals and scrotum of a baby boy, and can provide the scrotum with extra space compared with existing diapers, prevent the scrotum from being squeezed and close to the body, and increase the heat dissipation of the scrotum.

In Fig. 4, the cover layer and the base fabric of the diaper of the present invention constitute a composite structure 20. In this embodiment, the covering layer and the base fabric have the same shape and size. The size and shape of the cover and base fabric can also be inconsistent. The cover layer and base fabric are combined by the processing method of existing diaper cover layer and base fabric. On the inner surface of the composite structure 20 , typically also the inner surface of the cladding, there is an adhesive area 22 . The glue area 22 is used to glue the corresponding parts when the composite structure 20 is folded. On the outer surface of the composite structure, which is usually also the outer surface of the base fabric, there is an adhesive strip 24. Adhesive strips 24 are used to connect corresponding parts when the composite structure 20 is folded. Composite structure 20 has inward folds 27 and outward folds 29 . The creases 27 and 29 can be conveniently folded structures processed on the composite structure 20 using existing processing methods, such as pressed creases, or can be marked on the inner and outer surfaces of the composite structure 20 by printing Lines indicating where to fold. The composite structure 20 is divided into a front end and a rear end. Front and rear ends are also called front and rear. The back panel of the composite structure 20 has a waist member 40 for connecting the front panel and the back panel of the diaper. In different embodiments, the size and shape of the cover and base fabric can vary. The adhesive area 22 can be the area coated with the known adhesive used for diapers, or it can be a snap-in velcro. If a double nylon button is used, the corresponding nylon button is arranged on the area on the composite structure 20 corresponding to the viscose area 22 . Adhesive tape 24 can be glued, also can use nylon buckle.

In FIG. 5, the composite structure 20 is folded along creases 27 and 29 to form a three-dimensional tapered structure at the front end. The intersection of the crease 27 and the crease 29 is the apex of the three-dimensional structure. The covering layer is folded along the creases 27 and 29 to form a three-dimensional covering structure, which can cover the scrotum and genitals of the baby boy and quickly absorb and disperse urine. The base fabric is folded along the creases 27 and 29 to form a three-dimensional anti-leakage structure, and is tightly wrapped on the outside of the three-dimensional structure formed by the absorbent core layer and the covering layer. The adhesive area 22 glues the superimposed overlapped parts of the folded composite structure 20 together, so as to maintain the three-dimensional structure and prevent leakage. The adhesive tape 24 adheres the superimposed overlapping part of the folded composite structure 20 to the front end of the composite structure 20, so as to maintain the appearance of the diaper. The waist member 40 can connect the back panel and the front panel of the diaper together.

Fig. 6 is an unused shape of an embodiment of the diaper of the present invention. The absorbent core layer 10 is disposed between the cover layer and the base fabric, ie inside the composite structure 20 . The fixing method of the absorbent core layer 10 in the composite structure 20 adopts the processing method of existing diapers or paper absorbent sanitary products, such as glue bonding. The absorbent core layer 10 is a Y-shaped structure with two branches. There are process holes at the branch starting points of the two branches. The two branches of the absorbent core 10 are towards the front end of the composite structure 20 . When the absorbent core layer 10 is disposed within the composite structure 20 , the position of the process aperture coincides with the intersection of the creases 27 and 29 on the composite structure 20 . The edges of the two branches of the absorbent core layer 10 are arranged next to the crease 29 . The inner surface of the diaper has an adhesive area 22, and the outer surface of the diaper has an adhesive tape 24.

Fig. 7 is a usage state of an embodiment of the diaper of the present invention. The diaper is folded along the folds 27 and 29 at the front end of the composite structure 20 and bonded together along the glued areas. The two branches of the absorbent core layer 10 are also folded together at the same time. A three-dimensional structure is formed on the front end of the diaper. The three-dimensional structure is cone-shaped. When the baby boy wears the diaper of this embodiment, the genitals and scrotum of the baby boy are located in the three-dimensional tapered structure of the front panel of the diaper. Close to the body. Because the two branches of the absorbent core layer 10 are adjacent to each other after the diapers are folded and combined, when there is urine, the urine will be absorbed by the absorbent core layer 10 without splashing. The waist member 40 can connect the front panel and the back panel of the diaper together.

The front end of the absorbent core layer 10 in FIG. 8 has two adjacent branches 13 and 15 . The branches 13 and 15 are obtained by machining a slit in the absorbent core layer 10 . The angle between branch 13 and branch 15 is 0 degree. The position of the slit can be along the centerline of the main body of the absorbent core layer 10, or at a position off the centerline. A process hole 18 is formed at the root of the gap, that is, at the branch starting point of the branch 13 and the branch 15 . The overall shape of the absorbent core layer 10 is a rectangle. This structure of the absorbent core layer 10 can save materials and reduce costs during processing. On the upper surface of the branch 13 there is a connecting region 12 and on the lower surface of the branch 15 there is a connecting region 14 . The connecting areas 12 and 14 can be glued areas, nylon buttons, or snap buttons. The upper surface of the absorbent core 10 is covered with a cover layer having the same shape as the absorbent core. The upper surface of the absorbent core layer 10 may also be covered with a nonwoven material. The lower surface of the absorbent core may be covered with a base fabric or may be covered with a cover layer.

In Fig. 9, the branches 13 and 15 at the front end of the absorbent core layer 10 are cross-folded. Branch 13 and branch 15 are combined together. The branches 13 and 15 form a three-dimensional structure at the front end of the absorbent core layer 10 . The branches 13 and 15 are connected together through the connection area 12 and the connection area 14 to fix the shape of the three-dimensional structure of the absorbent core layer 10 . The absorbent core layer 10 forms a three-dimensional structure. The position where the process hole 18 is located is the top of the three-dimensional cone structure. The three-dimensional structure encloses a three-dimensional space.

In Fig. 10, the overall shape of the absorbent core layer 10 is a trapezoid. The overall shape of the absorbent core layer 10 may also be other shapes.

Fig. 11 is a plane state of another embodiment of the diaper of the present invention when not in use. The base fabric and cover layer form the composite structure 20 . The absorbent core layer 10 is disposed over the composite structure 20 . The absorbent core layer 10 is not disposed between the base fabric and the covering layer of the composite structure 20, but is disposed on the outer side of the covering layer of the composite structure, which is close to the baby's body. The absorbent core hugs the body of the wearer. The absorbent core 10 is joined to the composite structure 20 by the joining region 26 . The connection area 26 can be viscose, and also can be a snap-in velcro. The edge of the absorbent core layer 10 is connected to the composite structure 20 through a connecting region 28, which may be a seamed region, or may be a crimped or glued region. The front end of the absorbent core layer 10 is not connected to the composite structure 20 . The two branches of the absorbent core layer 10 are not connected to the composite structure 20 . The starting point of the two branches of the absorbent core layer, that is, the position of the process hole, coincides with the intersection of the creases 27 and 29 on the composite structure 20 . Composite structure 20 has waist attachment features 42 on the front panel and waist attachment features 40 on the back panel.

Fig. 12 is a state in use of another embodiment of the paper diaper of the present invention. First, the two branches 13, 15 at the front end of the absorbent core layer 10 are cross-folded and assembled together. After the two branches are combined, a three-dimensional structure is formed at the front end of the absorbent core layer 10 . The way of combination is cross-folding. The joining region 12 joins and secures the two branches of the absorbent core together. The two branches of the absorbent core layer 10 form a three-dimensional structure. The structure is a three-dimensional tapered structure. Composite structure 20 is folded along folds 27 and 29 . After the composite structure 20 is folded, a three-dimensional structure is formed at the front end. The front end of the covering layer is also folded to form a three-dimensional structure. The front end of the base fabric is also folded to form a three-dimensional structure. The three-dimensional structure formed by folding the composite structure is just outside the three-dimensional structure formed by the absorbent core layer 10 . After the composite structure is folded, the connection area connects the corresponding parts together to fix the three-dimensional structure of the composite structure. After folding, the front end of the diaper forms a three-dimensional structure. When the baby boy wears the diaper of this embodiment, the genitals and scrotum of the baby boy are located in the three-dimensional tapered structure of the front panel of the diaper. Close to the body. Because the two branches of the absorbent core layer 10 are overlapped after the diaper is folded, when there is urine, the urine will be absorbed by the absorbent core layer.

The absorbent core layer 10 in Fig. 13 is composed of three different branches 13, 15 and 17 obtained through independent processing. Wherein, there is an angle not equal to 0 degree between the branch 13 and the branch 15 . There is a vacancy between the front end of the branch 17 and the branch 13 and the branch 15, which serves as a process hole and is convenient for folding. The branch 13, the branch 15 and the branch 17 are three independently processed parts, which constitute the absorbent core layer 10 through combination. Branch 13, branch 15 and branch 17 are separated from each other. When the branches are arranged separately, the relative positions of the branches are fixed by the covering layer and the base cloth. The absorbent core 10 is Y-shaped. This structure of the absorbent core layer 10 not only has the advantage of no overlapping area after the Y-shaped structure is put together, but also has the advantage of saving raw materials in the cutting process. Branch 13, branch 15 and branch 17 may also be connected together. For example, the adjacent edges of the branches are connected together by means of stitching or adhesive bonding to form a whole absorbent core layer. When the absorbent core is composed of a plurality of independently manufactured branches, the branches can be separated from each other. When the absorbent core layer is composed of a plurality of independently processed branches, each branch can be connected to form a whole. When the absorbent core layer is composed of a plurality of independently processed branches, some of the branches can be connected together and some of the branches can be separated from other branches.

The absorbent core layer 10 in Figure 14 consisting of three separate branches is arranged in a composite structure 20, ie between the cover layer and the base fabric. The absorbent core layer 10 is fixedly connected with the covering layer and the base cloth by means of adhesive bonding. In this way, the position of each branch of the absorbent core layer 10 can be kept fixed, and it is also beneficial to the absorption of moisture. The branches 13 and 15 are arranged at the front end of the composite structure 20 . One side of the branch 15 is arranged adjacent to the crease 29 and one side of the branch 13 is arranged adjacent to the other outwardly facing fold. In use, the front end of the composite structure 20 is folded along the creases, and the branches 13 and 15 are brought together. Branches 13 and 15 form a three-dimensional structure. The covering layer and the base fabric also form a three-dimensional structure after being folded. In this way, the front end of the diaper forms a three-dimensional structure after being folded.

The front end of the absorbent core layer 10 in FIG. 15 has three branches 11 , 13 and 15 . Three branches can be folded along their respective roots. After folding, the three branches are combined. The way of combination is folding and flattening. When combined, the three branches form a three-dimensional solid structure with two vertices. The advantage of this structure is that it can further increase the space enclosed by the three-dimensional structure.

The front end of the absorbent core layer 10 in FIG. 16 has three branches 11 , 13 and 15 . These three branches are obtained by cutting slits in the absorbent core layer 10 . There are connecting areas on the branches, which can connect the cross-folded branches to each other, fix them and maintain their shape. A benefit of this absorbent core structure is material savings.

Figure 17 is a plan view of a composite structure comprising a cover layer and a base fabric for use with an absorbent core layer having three branches at the front end. The front end of the composite structure has two sets of creases and bonded areas. After the front end of the composite structure is folded along two sets of creases, a three-dimensional structure with two vertices can be formed on the front end of the diaper. The front end of the covering layer can be folded to form a three-dimensional structure with two vertices. The front end of the base fabric can be folded to form a three-dimensional structure with two vertices.

In Figure 18, the absorbent core with three branches at the front end is arranged in the composite structure, that is, it is arranged between the covering layer and the base fabric. The edge of the is next to the crease. Folding the diaper along the crease can form a three-dimensional three-dimensional structure of diapers with two vertices.

In Fig. 19, both the front end and the rear end of the absorbent core 10 have branched structures. There are two branches 13 and 15 at the front end and three branches at the back end. The branches at the front end of the absorbent core layer 10 can be combined to form a three-dimensional structure at the front end of the absorbent core layer. The branches at the rear end of the absorbent core layer 10 can be combined to form a three-dimensional structure at the rear end of the absorbent core layer. The three-dimensional structure formed by the combination of the branches at the front end of the absorbent core layer is used to accommodate the scrotum of the baby boy. The three-dimensional structure formed by the combination of branches at the rear end of the absorbent core layer can be used to accommodate the baby's defecation.

Fig. 20 is a plane shape of a diaper in which both the front panel and the rear panel can be folded to form a three-dimensional structure. At the front end of the diaper, that is, the front panel, the cover layer and the base fabric can be folded to form a three-dimensional structure. The two branches at the front end of the absorbent core layer can be combined to form a three-dimensional structure at the front end. The three-dimensional structure at the front of the diaper can accommodate the genitals and scrotum of a baby boy. At the rear end of the diaper, that is, the rear panel, the rear end of the covering layer can be folded to form a three-dimensional structure. The rear end of the base fabric can be folded to form a three-dimensional structure. The two branches at the rear end of the absorbent core can be combined to form a three-dimensional structure at the rear end of the absorbent core. The three-dimensional structure at the back end of the diaper can accommodate the baby's defecation.

In FIG. 21 , the absorbent core layer is formed by joining two separate panels through the joining region 50 . The attachment zone 50 is located at the rear end of the absorbent core. The connection area 50 can be a viscose area, and can also be a snap-in velcro. The edges of the two cut pieces are connected to each other by a connecting area 54, which may be a seam area or an adhesive area. The front end of the absorbent core has branches 13 and 15 . The included angle between branch 13 and branch 15 is a negative angle. The adjacent regions of branch 13 and branch 15 overlap each other. On the branch 13 there is a connecting region 12 and on the branch 15 there is a connecting region 14 . Branches 13 and 15 are able to be cross-folded. A three-dimensional structure can be formed after the branches 13 and 15 are cross-folded. The three-dimensional structure formed by the combination of the branch 13 and the branch 15 encloses a three-dimensional space. When the branches 13 and 15 are combined, the connecting regions 12 and 14 are connected to each other, maintaining the shape of the three-dimensional structure of the absorbent core.

The diapers of the present invention can also be processed into a form in which only the rear end has a three-dimensional structure for use by baby girls.

The diapers of the present invention can be used as adult diapers.
