Description

Technical Field

[0001] This utility model relates to the field of diaper technology, and more specifically, to an adult diaper with a replaceable core. Background Technology

[0002] Adult diapers are disposable paper-based incontinence products, a type of adult care product primarily intended for use by incontinent adults. The main performance characteristic of adult diapers is their absorbency, which depends primarily on the amount of fluff pulp and superabsorbent polymer.

[0003] Traditional adult diapers attach the core to the body of the user through the diaper body for absorption. After use, only the core is soiled, while the diaper body remains clean. The core and diaper body are fixedly connected, requiring the entire diaper to be replaced after each use, resulting in waste. To address this issue, adult diapers with replaceable cores are now available. These diapers use adhesive on the back of the core to attach it to the diaper body. However, attaching the core requires precise positioning; misalignment can cause discomfort. Current methods rely heavily on experience, which is cumbersome, inefficient, and affects comfort. To address these problems, a solution is proposed below. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an adult diaper with a replaceable core, which can achieve accurate installation of the core and the diaper body.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A replaceable core adult diaper includes a diaper body, a fastener installed at the waist of the diaper body for fixation, a core disposed on the inner side of the diaper body, and a plurality of positioning strips evenly distributed on the side of the diaper body, with adjacent positioning strips parallel to each other and arranged in a straight line. Both ends of each positioning strip are fixedly connected to the side of the diaper body, and positioning grooves are formed between the positioning strips and the diaper body. Positioning pieces are inserted into the plurality of positioning grooves, with the width of the positioning pieces being the same as the positioning grooves. One end of each positioning piece is fixedly connected to one end of the side of the core, and the other end of each positioning piece is detachably engaged with the other end of the side of the core. A first adhesive portion is disposed on the side of the core, and the first adhesive portion is adhered to the diaper body.

[0007] Preferably, the fastener includes a waistband, a hook and loop fastener, and a loop fastener surface. Two waistbands are provided, with one end of each waistband fixedly connected to both sides of one end of the pants body. The hook and loop fasteners are fixedly connected to the side of one end of each waistband, and the loop fastener surface is fixedly connected to the side of the pants body. The hook and loop fasteners are detachably connected.

[0008] Preferably, the positioning piece is provided with a plurality of second adhesive portions evenly on the side near the core, and the plurality of second adhesive portions are respectively bonded to the side of the core through the gap between two adjacent positioning strips.

[0009] Preferably, the first adhesive portion, the second adhesive portion, and the third adhesive portion are all made of traceless adhesive tape.

[0010] Preferably, one end of the positioning piece is arc-shaped.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] 1. This solution uses a positioning groove formed between the positioning strip and the pant body to position the positioning piece. Since the positioning groove and the positioning piece have the same width, the positioning piece is prevented from sliding upwards in the width direction. After the positioning piece is positioned, the position of the core is also fixed. The core is then bonded to the pant body through the first adhesive part, thus ensuring that the core is always installed in the same position on the pant body, thereby ensuring the comfort of subsequent users. In addition, the first adhesive part is set on the core, which ensures that the first adhesive part of the core is new every time the core is replaced, ensuring the bonding stability after replacement.

[0013] Second, two waistbands are used to wrap around the waist. The design of two waistbands ensures the stability of the garment. The waistbands are fixed to the waist of the pants by the hook and loop sides of the Velcro. The design of the hook and loop sides of the Velcro allows for reuse.

[0014] Third, the design of multiple second adhesive parts ensures the stability of the connection between the positioning piece and the core. In addition, the bonding of the core with multiple second adhesive parts also forms a snap-fit ​​on the adjacent positioning strips, preventing the core from moving.

[0015] Fourth, the third adhesive part can be used to bond one end of the core and the positioning piece, preventing one end of the core from lifting up.

[0016] 5. The residue-free tape avoids leaving adhesive residue when torn, making it convenient for the next use.

[0017] 6. The arc-shaped design makes it easy to pass through the positioning groove. Attached Figure Description

[0025] Example 1:

[0026] Please see Figure 1-5 A replaceable core adult diaper includes a diaper body 1. The waistband of the diaper body 1 is fitted with a fastener 2 for securing the diaper. The fastener 2 includes a waistband 8, hook and loop fasteners 9, and loop fasteners 10. Two waistbands 8 are provided, with one end of each waistband 8 fixedly connected to one side of one end of the diaper body 1. The design of two waistbands 8 ensures symmetrical fixation on both sides. The waistbands 8 are made of elastic material to avoid excessive pressure on the body and ensure wearing comfort. The hook and loop fasteners 9 are respectively connected to one side of the waistband 8. The side of the waistband is fixedly connected to the hook and loop fastener 10 and the side of the pant body 1. The hook and loop fastener hook surface 9 and the hook and loop fastener 10 are detachably connected. The area of ​​the hook and loop fastener hook surface 9 is smaller than that of the hook and loop fastener 10. The tightness of the waistband 8 can be adjusted by adjusting the position of the hook and loop fastener hook surface 9 on the hook and loop fastener 10 to accommodate different waist sizes. The fact that the hook and loop fastener hook surface is smaller than the hook and loop fastener 10 ensures that the hook and loop fastener hook surface 9 fits completely with the hook and loop fastener 10, avoiding discomfort caused by the hook and loop fastener hook surface 9 coming into contact with the user's skin.

[0027] The sides of the trouser body 1 are evenly provided with several positioning strips 4, which are parallel to each other and arranged in a straight line. Both ends of the positioning strips 4 are fixedly connected to the sides of the trouser body 1. Positioning grooves 5 are formed between the positioning strips 4 and the trouser body 1. Positioning pieces 6 are inserted into the several positioning grooves 5. The width of the positioning pieces 6 is the same as that of the positioning grooves 5. The fact that the width of the positioning pieces 6 is the same as that of the positioning grooves 5 can prevent the positioning pieces 6 from sliding along the width direction inside the positioning grooves 5, thus achieving a limiting effect. One end of the positioning piece 6 is arc-shaped 13. The arc-shaped design 13 makes it easy to insert the positioning piece 6 into the positioning grooves 5, thus facilitating replacement.

[0028] The non-arc end face of the positioning piece 6 is connected to the core 3. The core 3 and one end of the positioning piece 6 are bonded together with adhesive. Adhesive bonding ensures a stable connection and is a simple process. A third adhesive portion 12 is provided on the arc end face of the positioning piece 6. This third adhesive portion 12 is used to fix and connect to one end of the core 3, and it is bonded to the center of the core 3. This prevents one end of the core 3 from lifting, ensuring a complete fit and thus guaranteeing user comfort. Several second adhesive portions 11 are evenly arranged on the positioning piece 6. These second adhesive portions 11 are respectively arranged between the gaps of two adjacent positioning strips 4, and they are bonded to the core 3. The bonding can also limit the positioning strips 4, preventing the positioning piece 6 from moving in the length direction, ensuring the position, preventing gaps between the core 3 and the positioning piece 6, and ensuring that the core 3 is tightly attached to the positioning piece 6, thus ensuring wearing comfort and connection stability. The core 3 has a first bonding part 7 on its side. There are two first bonding parts 7, which are symmetrically arranged on one side of the core 3. The first bonding parts 7 are bonded to the pant body 1, thus ensuring that all four sides of one side of the core 3 are fixed, effectively preventing curling and ensuring wearing comfort. At the same time, the first bonding parts 7 and the second bonding parts 11 are arranged perpendicularly to ensure the stability of the bonding of the core 3.

[0029] The positioning groove 5 positions the positioning piece 6. Once the positioning piece 6 is positioned, the position of the core 3 is also fixed, ensuring that the core 3 is always installed in the same position on the pants body 1, thus ensuring the comfort of subsequent users. In addition, the first adhesive part 7 is set on the core 3, which ensures that the first adhesive part 7 on the core 3 is new every time the core 3 is replaced, ensuring the stability of the adhesive after replacement. Furthermore, the first adhesive part 7, the second adhesive part 11, and the third adhesive part 12 all use traceless adhesive tape, which can avoid adhesive residue and facilitate the next use.

[0030] Working principle:

[0031] In use, the user takes the new core 3. The first adhesive part 7, the second adhesive part 11, and the third adhesive part 12 of the core 3 and the positioning piece 6 each have corresponding release paper, which can protect the first adhesive part 7, the second adhesive part 11, and the third adhesive part 12 respectively. The arc end of the positioning piece 6 is passed through the positioning groove 5 in sequence. Then, the release paper on the first adhesive part 7 and the release paper on the second adhesive part 11 are peeled off. The core 3 and the positioning piece 6 are attached to the core 3 in sequence from the end fixed to the positioning piece 6 to the other end. At the same time, the core 3 will also be attached to the pants body 1. Finally, the release paper of the third adhesive part 12 is peeled off and one end of the positioning piece 6 is attached to one end of the core 3 to complete the installation.

[0032] By attaching the hook and loop fasteners 9 on the waistband 8 to the loop fasteners 10 on the pant body 1, the waist of the pant body 1 is wrapped and fixed, making it convenient to wear the pant body 1.
