Problems solved by technology

The front waist sticker used by most of the diapers on the market is a smooth plastic film fixed on the outer surface of the front end of the body. Correspondingly, it is fixed on the rear end of the body and can be repeatedly bonded and separated from the front waist sticker. The adhesive sheet is a plastic film coated with an adhesive layer. The advantage of using the above structure is that the diaper can be firmly fixed on the baby's buttocks, and it is not easy to fall off. The disadvantage is that the adhesive sheet is easy to produce sharp corners when used to scratch the baby. or the skin of other users; in addition, since the existing adhesive sheet is only composed of a single plastic film and an adhesive layer, in order to ensure that the adhesive sheet has the performance of being repeatedly torn off from the front waist, the plastic film needs to be selected with Certain strength and thickness of PE and PVC materials, resulting in reduced comfort
In addition, the material of the glossy plastic film used in the front waist sticker is relatively hard, its hand feeling and visual effect are poor, and the product grade is low
[0003] Or, in order to improve the product grade, the front waist sticker of the diaper can also be made of non-woven fabric, and the two sides of the front waist sticker and the outer surface of the rear end of the diaper body are provided with corresponding magic buttons. However, as a A disposable product, the production cost of the above-mentioned gluing mechanism is too high, resulting in great waste

Embodiment 1

[0029] like figure 1 As shown in , the fastening mechanism for diapers includes a front waist sticker 2 and two stickers 3 arranged on the diapers.

[0030] like figure 2 As shown in , the front waist sticker 2 is a sheet-like strip body, which consists of a semi-adhesive layer 21, a matte plastic film layer 22 and a hot-melt adhesive layer that are sequentially fixed by the coating of a release agent material. 23, and bonded to the outer surface of the front end of the diaper through the hot melt adhesive layer 23.

[0031] like image 3 and Figure 4 As shown in , the adhesive sheet 3 includes a liner film 32 and a base film 31, the liner film 32 is composed of a silicone oil layer 321 fixed in sequence, a plastic film layer 322 and a hot melt adhesive layer 323, and the base film 31 is fixed in sequence A silicone oil layer 311 (provides anti-adhesive performance), a non-woven fabric layer 312 for providing a soft outer surface, a PP coating layer 313 and a hot melt ad...

Embodiment 2

[0038] like Figure 5 As shown in , the difference between Example 2 and Example 1 is that the adhesive sheet bottom film 31a uses a PE film layer 313a with a thickness of 8-40 μm to replace the PP coating film 313 in the adhesive sheet 3 . The structure of the remaining parts and the materials used are exactly the same as in Example 1.

Abstract

The invention discloses an improved adhering fastener mechanism for a paper diaper. Each adhering sheet of the paper diaper comprises a lining membrane and a bottom membrane, wherein each lining membrane comprises a silicone oil layer, a plastic film layer and a hot melt adhesive layer which are sequentially fixed; and each bottom membrane comprise a silicone oil layer, a non-woven fabric layer used for providing a flexible outer surface, a plastic film layer and a hot melt adhesive layer which are sequentially fixed. The adhering fastener mechanism of the paper diaper has the advantages of simple structure and low production; and when a paper diaper with the adhering fastener mechanism is worn on a human body, the part which is exposed outside and in direct contact with the human body is not a hard plastic film any more but is a flexible non-woven fabric, thus the user feels more comfortable.

Description

technical field [0001] The invention relates to a fastening mechanism, in particular to an improved fastening mechanism for diapers. Background technique [0002] Commercially available diapers all include a body, the body is provided with a front end for wrapping the front waist of the human body, and a rear end for wrapping the back waist of the human body, and a front waist sticker is fixedly arranged on the outer surface of the front end of the body. , both sides of the outer surface of the rear end of the body are provided with an adhesive sheet, which is arranged corresponding to the two ends of the front waist sticker, and can be repeatedly bonded to the outer surface of the front waist sticker to form a The trousers type is used by infants or other people with difficulties. The front waist sticker and the two stickers together constitute the fastening mechanism of the diaper. The front waist sticker used by most of the diapers on the market is a smooth plastic film ...
