Abstract
Description
Technical Field
[0001] This utility model relates to the field of diapers, specifically an adjustable-size diaper. Background Technology
[0002] Currently, the largest size of baby diapers with waistbands on the market is generally 2XL or 3XL, while pant-style diapers offer even larger options like 4XL and 5XL. Parents typically choose pant-style diapers after their babies learn to walk, as they are convenient and provide a better wrap. However, a drawback is that changing them outdoors requires removing the baby's pants and shoes, which can be inconvenient in cold weather and can easily cause the baby to catch a cold. Therefore, there is a certain market demand for extra-large waistband diapers, but the demand is not as high as for other sizes. Developing a larger size specifically for waistband diapers would be difficult to justify in terms of cost and profit. Therefore, upgrading existing diapers to accommodate babies with larger waists is one of the future growth directions for many manufacturers. Utility Model Content
[0003] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.
[0004] This utility model provides the following technical solutions to solve one or more of the above-mentioned technical problems:
[0005] An adjustable-size diaper includes a diaper body and a waistband, wherein the waistband has an extension section with a lateral length S of 5-30 mm.
[0006] In some embodiments, the lateral length S of the growth segment is 10-20 mm.
[0007] In some embodiments, the waist patch includes a composite segment and a connecting segment, the composite segment and the connecting segment being respectively disposed on both sides of the elongation segment.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0027] Combination Figures 1 to 3 As shown in the embodiment, this invention proposes an adjustable-size diaper, including a diaper body 1 and waist tabs. Waist tabs are provided on both the left and right sides of the diaper body 1. Each waist tab has a composite section 201, a connecting section 202, and an elongation section 205. The composite section 201 and the connecting section 202 are respectively located on both sides of the elongation section 205.
[0028] Composite section 201 is fixedly connected to the diaper body 1;
[0029] The connecting section 202 includes a main body and a magic hook 203, the magic hook 203 being fixed to the main body;
[0030] The lateral length S of the growth segment 205 is 5-30 mm, preferably 10-20 mm.
[0031] Normally, the waist tabs are fixed to the left and right sides of the back waist of the diaper body 1. When in use, they are attached to the side of the front waist of the diaper body 1 away from the skin by a magic hook to form a closed circumferential waistband. The total horizontal length of the waist tab is about 75 mm. After adding the extension section 205, the total horizontal length of the waist tab can reach about 95 mm. Adding the extension section 205 can expand the adjustable area of the circumferential waistband size.
[0032] In some specific implementations, the longitudinal length of the composite segment 201 is equal to the longitudinal length of the extension segment 205, while the longitudinal length of the extension segment 205 is greater than the longitudinal length of the connecting segment 202. This design effectively lengthens the lumbar support while reducing the constricting sensation on the user's waist. Both the composite segment 201 and the extension segment 205 can be rectangular, while the connecting segment 202 can be U-shaped. Compared to the production of a lumbar support consisting of the original composite segment 201 and connecting segment 202, the production of a lumbar support including the composite segment 201, connecting segment 202, and extension segment 205 generates less waste.
[0033] The composite section 201, the growth section 205, and the main body can be cut and formed as a single piece.
[0034] In some specific implementations, the growth segment 205 and the main body combine to form an extended waistband. The extended waistband is folded towards the diaper body 1. The growth segment 205 is pressed together with the composite segment 201 to form longitudinally arranged dotted pressing portions. For example, the pressing of the growth segment 205 and the composite segment 201 forms 1-4 rows of dotted pressing portions, preferably 1-2 rows; the spacing between adjacent rows of dotted pressing portions is 5-15 mm, preferably 5-10 mm; each row of dotted pressing portions includes 2-6 longitudinally arranged pressing points 204, preferably 2-3 pressing points 204. This allows consumers to further adjust the diaper waist size by selecting to open different rows of dotted pressing portions.
[0035] The peel strength of the above-mentioned dotted pressing part can be 4-15N, preferably 6-10N.
[0036] The aforementioned undisclosed matters can be directly implemented using existing technologies, so they will not be elaborated upon here.
[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
