The disposal sticker 101 is folded by stacking layers, and two of the three layers are unfolded when in use, and then the unfolded length is used to tie and stick it firmly. The existing three-layer Z-shaped design is a relatively thick plastic film with a total gram weight of about 250 grams per square meter. The product is hard and thick, and the cost is high. It is also not environmentally friendly, so it needs to be improved.

[0040] refer to Figure 3-Figure 14 .

[0041] This embodiment provides a disposal patch for diapers, which adopts a two-layer design. The Z-shaped three-layer structure is reduced to a two-layer structure design, with a total weight of about 170 grams per square meter. The design can reduce the weight by about 1 / 3, greatly reduce costs, reduce the amount of plastic, and be more environmentally friendly. At the same time, the thickness is also greatly reduced from about 520um for three layers to 250um for two layers, which greatly reduces the hard block feeling produced by the disposal patch 1, and can double the length of each roll, reduce the cost of roll change and transportation, and better cut and increase the life of the cutter.

[0042] Specifically, the present embodiment provides a disposal patch for diapers, the disposal patch 1 comprising a bottom layer 11 and a surface layer 12; the surface layer 12 comprises a surface layer adhesive 124, an extensible film 125 and a first release coating 126; the bottom layer 11 comprises a bottom layer adhesive 112, a bottom layer film 113 and a second release coating 111.

[0043] The bottom film 113 includes a connection area 114 . The surface layer 12 is provided with a front section, a middle section and a rear section. One side of the middle section of the surface layer 12 is connected to the connection area 114 . The connection area 114 is close to the rear section of the surface layer 12 .

[0044] The bottom layer adhesive 112 is adhered to the diaper 2, the surface layer adhesive 124 of the rear section of the surface layer 12 is adhered to the diaper 2, and the rear section of the surface layer 12 is a fixed area 121; the middle section of the surface layer 12 is an extensible area 122; the front section of the surface layer 12 includes an opening film 128, and the front section of the surface layer 12 is an opening area 123.

[0045] A suitable pattern or LOGO is printed on the surface layer 12 where the opening area 123 is located to facilitate identification of the opening area 123 , and an extendable arrow indication is printed on the opening area 123 so that the user can identify that the surface layer 12 is stretchable.

[0046] The bottom layer 11 is made of a film or a thin cloth, and the bottom layer adhesive 112 is fixed on the diaper 2 by hot melt adhesive, water adhesive or oil adhesive. The surface layer 12 is made of an easily stretchable film or non-woven fabric, which can be stretched when used. A small force can be applied to stretch the surface layer 12 to extend it to about 1-3 times the length without breaking easily. The stretching can reach or even exceed the effective length of the three-layer patch, so as to meet the length requirement of the disposable patch 1 when used.

[0047] The stretchable part of the surface layer 12 is mainly arranged in the middle section of the surface layer 12, and the stretchable film 125 is a stretchable plastic film, and the stretchable film 125 is made of CPP, EVA or MPE. Alternatively, the stretchable film 125 is a stretchable elastic non-woven fabric.

[0048] The rear section of the surface layer 12 is attached to the diaper 2 or the bottom film 113 by the surface layer adhesive 124, as the fixing area 121, and the extension of the extensible film 125 is suppressed by the setting of being attached to the diaper 2 or the bottom film 113, forming an inextensible film structure. The front section of the surface layer 12 is provided with an opening area 123, which cannot be sticky so as to be lifted off the second release coating 111, and the opening area 123 is preferably set to be inextensible; the opening film 128 is a colored film. The opening film 128 is used to suppress the extension of the extensible film 125, forming an inextensible film structure.

[0049] First embodiment

[0050] One side of the bottom film 113 folds the non-release surface upward to form a folded edge area, and the folded edge area is the connection area 114. The surface layer glue 124 can be made of hot melt glue, water glue, or oil glue. The opening film 128 is arranged on the surface of the surface layer glue 124, and a reinforcing glue layer 129 is arranged on the lower surface of the opening film 128. The reinforcing glue layer 129 can be made of hot melt glue, water glue, or oil glue. With the reinforcing glue layer 129 arranged under the opening film, the glue is not easy to extend and thin, and the viscosity of the front section of the surface layer 12 is further increased. With the surface glue layer at the extensible film 125, it is more firmly attached to the diaper 2.

[0051] The opening film 128 and the second release coating 111 form a separation structure, and the opening film 128 is used to be manually lifted so that the surface adhesive 124 leaves the second release coating 111 and is used to be attached to the diaper 2. The opening film 128 is a colored film and has identification.

[0052] The material of the stretchable film 125 can be CPP, EVA, MPE, or elastic non-woven fabric. A first release coating 126 is formed on the stretchable film 125 .
