Description

Technical Field

[0001] The invention relates to a diaper, in particular to a composite core diaper and a manufacturing process thereof. Background Art

[0002] Diapers are commonly used daily necessities, usually including a skin-friendly layer, a core layer and a bottom layer. For sensitive users (such as infants and young children), diapers need to be changed in a timely manner. In order to determine whether the user has urinated, traditional diapers usually have a color-changing strip on the bottom layer to display, but when the user puts on the pants, the color-changing strip cannot be observed and judged.

[0003] Some patent documents disclose that sensors are provided inside diapers to make judgments and give alarms, but the sensors are provided inside diapers, which results in high cost of use. Summary of the invention

[0004] In view of the above problems, the present invention provides a composite core diaper and a manufacturing process thereof.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A composite core diaper, comprising a skin-friendly layer, a composite core layer and a waterproof and breathable bottom layer arranged in sequence;

[0007] The waterproof and breathable bottom layer has a matching structure for matching with an external reminder device, and the matching structure includes:

[0008] An opening is provided on the waterproof and breathable bottom layer and penetrates the waterproof and breathable bottom layer;

[0009] An adhesive layer is located on a side of the waterproof and breathable bottom layer away from the composite core layer and is located on the entire periphery of the opening;

[0010] The first bonding piece of the Velcro is fixed on the side of the waterproof and breathable bottom layer away from the composite core layer and is located at the periphery of the adhesive layer;

[0011] The sealing sheet is located on the side of the waterproof and breathable bottom layer away from the composite core layer and is bonded to the adhesive layer. The middle of the sealing sheet covers the opening, and the outer edge of the sealing sheet covers the first bonding sheet of the Velcro.

[0012] The reminder device includes a body, an extension line, an alarm element, a battery, a humidity sensor and a controller;

[0013] The battery, humidity sensor and controller are installed on the body, and the battery and humidity sensor are electrically connected to the controller;

[0014] One end of the extension line is connected to the body, and the other end is equipped with the alarm element, and the alarm element is electrically connected to the controller through the extension line;

[0015] The sensing head of the humidity sensor protrudes outward;

[0016] The main body has a sealing ring located at the periphery of the sensor head and a second Velcro bonding piece located at the periphery of the sealing ring;

[0017] When the matching structure cooperates with the reminder device, the sealing sheet is removed, the second combining sheet of the Velcro contacts the first combining sheet of the Velcro, so that the body is fixed on the waterproof and breathable bottom layer, the sealing ring contacts and cooperates with the adhesive layer, and the sensing head of the humidity sensor extends into the opening.

[0018] The composite core diaper of the present application is provided with a matching structure, which can be installed with an external reminder device. A specific installation method is: tear off the sealing sheet to expose the opening, press the body of the reminder device toward the opening, extend the sensing head of the humidity sensor into the opening, and make the sealing ring contact and match with the adhesive layer, and the second bonding piece of the Velcro contacts with the first bonding piece of the Velcro, so that the body is fixed to the waterproof and breathable bottom layer. After actual wearing, the flexible extension line extends to the upper end surface of the pants, and after bending, the alarm element is located on the outside of the pants. After the user urinates, the urine is absorbed by the composite core layer, and the humidity at the opening increases. When it exceeds the preset value, the controller controls the alarm element to work, such as emitting light or sound. In order to prevent the sound from scaring or affecting the user, the alarm element is preferably a light-emitting element.

[0019] The sealing sheet of the present application cooperates with the adhesive layer to seal the opening, and can be used as an ordinary diaper even without the reminder device; the outer edge of the sealing sheet covers the first bonding sheet of the Velcro, and the first bonding sheet of the Velcro is a fluffy structure (hook surface or fleece surface), that is, the outer edge of the sealing sheet is not bonded and fixed to other structures, so that the edge of the sealing sheet can be easily grasped and a force can be applied to separate the sealing sheet from the adhesive layer. The reminder device of the present application is an independent device, which can be reused and has a low cost of use.

[0020] This application is especially suitable for infants and young children with sensitive skin.

[0021] In one embodiment of the present invention, the composite core layer includes a first anti-permeability layer, a first covering layer, an absorption layer, a second covering layer and a second anti-permeability layer arranged in sequence, the first anti-permeability layer is located on one side of the skin-friendly layer, and the second anti-permeability layer is located on one side of the waterproof and breathable bottom layer.

[0022] In one embodiment of the present invention, the absorption layer includes fluffy cotton and a water-absorbing resin on the fluffy cotton.

[0023] In one embodiment of the present invention, the waterproof and breathable bottom layer includes a PE bottom film layer and a hot air bottom film layer, and the PE bottom film layer is located on one side of the composite core layer.

[0024] In actual use, preferably, the material of the sealing sheet is also PE.

[0025] In one embodiment of the present invention, one of the first connecting piece of the Velcro and the second connecting piece of the Velcro has a fleece surface, and the other has a hook surface.

[0026] In one embodiment of the present invention, the composite core diaper has a crotch area, a crotch front area and a crotch rear area when worn; the opening is located in the crotch front area or the crotch rear area.

[0027] The opening is arranged in the front area of ​​the crotch or the rear area of ​​the crotch, so that a relatively flat space can be provided for accommodating the main body, and the reminder device has less influence on the comfort of the diaper.

[0028] In one embodiment of the present invention, both sides of the composite core diaper are provided with side leakage prevention edges respectively matched with the thigh roots, and two groups of arranging elements are arranged on the side leakage prevention edges, and the arranging elements include a gripping portion and a plurality of elastic cords, one end of the elastic cord is fixed to the gripping portion, and the other end is bonded to the side leakage prevention edges, and different elastic cords are bonded to different areas of the side leakage prevention edges;

[0029] After the composite core diaper is put on, the elastic cord can drive the anti-side leakage sealing edge to flip outward by pulling the gripping part outward, and when the force applied to the gripping part exceeds a set value, the elastic cord can be detached from the anti-side leakage sealing edge.

[0030] In practice, when putting on a diaper, one needs to insert one's fingers between the thigh and the side leakage prevention edge, move along the side leakage prevention edge, and move the fingers outward at the same time to turn the side leakage prevention edge outward. This operation method is not hygienic, and sometimes the fingers (nails) can easily hurt the skin of infants and young children. The present application can achieve the same function through the finishing element, and the operation is more convenient and hygienic.

[0031] The present application also discloses a diaper assembly, including the composite core diaper described above and a reminder device, wherein the reminder device includes a body, an extension line, an alarm element, a battery, a humidity sensor and a controller;

[0032] The battery, humidity sensor and controller are installed on the body, and the battery and humidity sensor are electrically connected to the controller;

[0033] One end of the extension line is connected to the body, and the other end is equipped with the alarm element, and the alarm element is electrically connected to the controller through the extension line;

[0034] The sensing head of the humidity sensor protrudes outward;

[0035] The main body is provided with a sealing ring located at the outer periphery of the induction head and a second combination piece of Velcro located at the outer periphery of the sealing ring.

[0036] In one embodiment of the present invention, the main body and the extension line are flat; and the alarm element includes an LED light.

[0037] The flat structure takes up little space and does not easily affect comfort.

[0038] The present application also discloses a manufacturing process of a composite core diaper, comprising the following steps:

[0039] Prepare or prepare the skin-friendly layer, the composite core layer and the waterproof and breathable bottom layer;

[0040] Openings penetrating the waterproof and breathable bottom layer are processed at equal intervals on the waterproof and breathable bottom layer, and an annular adhesive layer is adhered to the waterproof and breathable bottom layer, and the adhesive layer is covered on the corresponding openings, and the first bonding piece of the annular Velcro is fixed to the waterproof and breathable bottom layer by bonding or welding, and the first bonding piece of the Velcro is covered on the corresponding adhesive layer, and the sealing piece is pressed against the adhesive layer to fix the sealing piece to the waterproof and breathable bottom layer and to cover the corresponding opening and the corresponding first bonding piece of the Velcro;

[0041] The skin-friendly layer, the composite core layer and the waterproof and breathable bottom layer are sequentially compositely connected and then cut into individual products, wherein the adhesive layer, the Velcro and the sealing sheet are all located on the side of the waterproof and breathable bottom layer away from the composite core layer.

[0042] The beneficial effects of the present invention are as follows: the composite core diaper of the present application is provided with a matching structure, and an external reminder device can be installed. The reminder device can promptly remind the user after urinating, so that the diaper can be replaced in time; the reminder device of the present application is an independent device, which can be reused and has a low cost of use.

[0058] Example 1

[0059] like Figure 1 , Figure 2 and Figure 8 As shown, a composite core diaper 100 comprises a skin-friendly layer 1, a composite core layer 2 and a waterproof and breathable bottom layer 3 arranged in sequence;

[0060] like Figure 1 and Figure 2 As shown, the waterproof and breathable bottom layer 3 has a matching structure 3a for matching with the external reminder device 200, and the matching structure 3a includes:

[0061] An opening 31 is provided in the waterproof and breathable bottom layer 3 and penetrates the waterproof and breathable bottom layer 3;

[0062] The adhesive layer 32 is located on the side of the waterproof and breathable bottom layer 3 away from the composite core layer 2 and is located on the entire periphery of the opening 31;

[0063] The first combination sheet 33 of the Velcro is fixed on the side of the waterproof and breathable bottom layer 3 away from the composite core layer 2 and is located at the periphery of the adhesive layer 32;

[0064] The sealing sheet 34 is located on the side of the waterproof and breathable bottom layer 3 away from the composite core layer 2 and is bonded to the adhesive layer 32. The middle of the sealing sheet 34 covers the opening 31, and the outer edge of the sealing sheet 34 covers the first bonding sheet 33 of the Velcro.

[0065] like Figure 3 , Figure 5 and Figure 6 As shown, the reminder device 200 includes a body 201, an extension line 202, an alarm element 203, a battery (omitted and not shown in the figure), a humidity sensor 204 and a controller (omitted and not shown in the figure);

[0066] The battery, humidity sensor 204 and controller are installed on the body 201, and the battery and humidity sensor 204 are electrically connected to the controller;

[0067] One end of the extension line 202 is connected to the body 201, and the other end is installed with an alarm element 203, and the alarm element 203 is electrically connected to the controller through the extension line 202;

[0068] The sensing head 2041 of the humidity sensor 204 protrudes outward;

[0069] The body 201 has a sealing ring 205 located at the periphery of the induction head 2041 and a second Velcro bonding piece 206 located at the periphery of the sealing ring 205;

[0070] When the matching structure 3a is matched with the reminder device 200, the sealing sheet 34 is removed, the second combining sheet 206 of the Velcro contacts the first combining sheet 33 of the Velcro, so that the main body 201 is fixed on the waterproof and breathable bottom layer 3, the sealing ring 205 contacts and matches the adhesive layer 32, and the sensing head 2041 of the humidity sensor 204 extends into the opening 31.

[0071] The composite core diaper 100 of the present application is provided with a matching structure 3a, which can be installed with an external reminder device 200. A specific installation method is to tear open the sealing sheet 34 to expose the opening 31 (see Figure 2 and Figure 4 ), press the body 201 of the reminder device 200 toward the opening 31, so that the sensing head 2041 of the humidity sensor 204 extends into the opening 31, and the sealing ring 205 contacts and cooperates with the adhesive layer 32, and the second bonding piece 206 of the Velcro contacts and the first bonding piece 33 of the Velcro, so that the body 201 is fixed to the waterproof and breathable bottom layer 3 (see Figure 5 and Figure 6 ).

After the user urinates, the urine is absorbed by the composite core layer 2, and the humidity at the opening 31 increases. When it exceeds a preset value, the controller controls the alarm element 203 to work, such as emitting light or sound. In order to prevent the sound from scaring or affecting the user, the alarm element 203 is preferably a light-emitting element.

[0072] The sealing sheet 34 of the present application cooperates with the adhesive layer 32 to seal the opening 31, and can be used as a common diaper even without the reminder device 200; the outer edge of the sealing sheet 34 covers the first combination sheet 33 of the Velcro, and the first combination sheet 33 of the Velcro is a fluffy structure (hook surface or fleece surface), that is, the outer edge of the sealing sheet 34 is not bonded and fixed to other structures, so that the edge of the sealing sheet 34 can be easily grasped and a force can be applied to separate the sealing sheet 34 from the adhesive layer 32. The reminder device 200 of the present application is an independent device, which can be reused and has a low cost of use.

[0073] This application is especially suitable for infants and young children with sensitive skin.

[0074] like Figure 3 and Figure 6 As shown, in this embodiment, the main body 201 and the extension line 202 are flat; the alarm element 203 includes an LED light.

[0075] The flat structure takes up little space and does not easily affect comfort.

[0076] like Figure 7 As shown, in this embodiment, the composite core layer 2 includes a first anti-permeability layer 21, a first covering layer 22, an absorption layer 23, a second covering layer 24 and a second anti-permeability layer 25 which are arranged in sequence. The first anti-permeability layer 21 is located on one side of the skin-friendly layer 1, and the second anti-permeability layer 25 is located on one side of the waterproof and breathable bottom layer 3.

[0077] In this embodiment, the absorption layer 23 includes fluffy cotton and water-absorbing resin on the fluffy cotton.

[0078] In this embodiment, the waterproof and breathable bottom layer 3 includes a PE bottom film layer and a hot air bottom film layer, and the PE bottom film layer is located on one side of the composite core layer 2. In actual use, preferably, the material of the sealing sheet 34 is also PE.

[0079] In this embodiment, one of the first connecting piece 33 of the Velcro and the second connecting piece 206 of the Velcro has a fleece surface, and the other has a hook surface.

[0080] In this embodiment, the composite core diaper 100 has a crotch area 101 , a crotch front area 102 and a crotch rear area 103 when worn; the opening 31 is located in the crotch front area 102 or the crotch rear area 103 .

[0081] The opening 31 is arranged in the front crotch area 102 or the rear crotch area 103 so that a relatively flat space can be provided to place the body 201 , and the reminder device 200 has little influence on the comfort of the diaper.

[0082] like Figure 8 As shown, in this embodiment, both sides of the composite core diaper 100 are provided with side leakage prevention edges 104 respectively matched with the thigh roots.

[0083] This embodiment further discloses a diaper assembly, including the composite core diaper 100 of this embodiment and a reminder device 200 .

[0084] This embodiment also discloses a manufacturing process of a composite core diaper 100, which is used to manufacture the composite core diaper 100 of this embodiment, and includes the following steps:

[0085] Prepare or prepare the skin-friendly layer 1, the composite core layer 2 and the waterproof and breathable bottom layer 3;

[0086] Openings 31 penetrating the waterproof and breathable bottom layer 3 are processed at equal intervals on the waterproof and breathable bottom layer 3, and an annular adhesive layer 32 is adhered to the waterproof and breathable bottom layer 3, and the adhesive layer 32 is covered on the corresponding openings 31, and the first bonding piece 33 of the annular Velcro is fixed to the waterproof and breathable bottom layer 3 by bonding or welding, and the first bonding piece 33 of the Velcro is covered on the corresponding adhesive layer 32, and the sealing piece 34 is pressed toward the adhesive layer 32, so that the sealing piece 34 is fixed to the waterproof and breathable bottom layer 3 and the sealing piece 34 covers the corresponding opening 31 and the corresponding first bonding piece 33 of the Velcro;

[0087] The skin-friendly layer 1 , the composite core layer 2 , and the waterproof and breathable bottom layer 3 are sequentially compositely connected and then cut into individual products, wherein the adhesive layer 32 , the Velcro and the sealing sheet 34 are all located on the side of the waterproof and breathable bottom layer 3 away from the composite core layer 2 .

[0088] Example 2

[0089] like Fig. 9 As shown, the difference between this embodiment and embodiment 1 is that two groups of arranging elements 105 are provided on the side leakage prevention edge seal 104, and the arranging element 105 includes a gripping portion 1051 and a plurality of elastic ropes 1052, one end of the elastic rope 1052 is fixed to the gripping portion 1051, and the other end is bonded to the side leakage prevention edge seal 104, and different elastic ropes 1052 are bonded to different areas of the side leakage prevention edge seal 104;

[0090] After putting on the composite core diaper 100, the elastic cord 1052 can drive the anti-side leakage sealing edge 104 to turn outward by pulling the gripping portion 1051 outward, and when the force applied to the gripping portion 1051 exceeds the set value, the elastic cord 1052 can be detached from the anti-side leakage sealing edge 104. In fact, after putting on the diaper, the fingers of the person need to be inserted between the thigh and the anti-side leakage sealing edge 104, move along the anti-side leakage sealing edge 104, and move the fingers outward at the same time to turn the anti-side leakage sealing edge 104 outward. This operation method is not hygienic, and sometimes the fingers (nails) can easily hurt the skin of infants and young children. The present application can achieve the same function through the finishing element 105, and the operation is more convenient and hygienic.

[0091] The above description is only a preferred embodiment of the present invention, and does not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention and the drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the present invention.
