Abstract
Description
Technical Field
[0001] This utility model is an ultra-thin environmentally friendly sanitary pad, belonging to the field of sanitary pad technology. Background Technology
[0002] Panty liners are a type of sanitary napkin. They are convenient to use and very popular among women.
[0003] After use, sanitary pads are usually difficult to degrade and can easily cause environmental pollution. Therefore, in view of the above situation, an ultra-thin and environmentally friendly sanitary pad is proposed. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultra-thin and environmentally friendly sanitary pad to solve the existing problems.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an ultra-thin environmentally friendly sanitary pad, the structure of which includes a pad body, protective wings on both sides of the pad body, a core cavity on the pad body, a barrier strip surrounding the core cavity, and a first core inside the core cavity, the first core being detachably connected to the core cavity.
[0006] Furthermore, the core cavity is provided with a bonding part, and a cavity is provided above the bonding part. The first core is provided with an adhesive part, and an arc-shaped strip is provided on the adhesive part. The first core is attached to the bonding part through the adhesive part, and the arc-shaped strip is located in the cavity.
[0007] Furthermore, a second core is provided inside the core cavity, and the first core is placed on top of the second core.
[0008] Furthermore, the second core is composed of a first absorbent layer and a bottom layer, wherein the bottom layer is made of bio-based plastic.
[0009] Furthermore, the first core is composed of a surface layer, a bamboo charcoal layer, and a second absorption layer. The second absorption layer has an arc-shaped structure on top, and guide strips are provided on both sides of the second absorption layer. The guide strips are attached to the second core.
[0010] The beneficial effects of this utility model are:
[0011] With a removable first core, the first core can be replaced directly when menstrual flow is light at the beginning and end of the menstrual period, instead of replacing the entire panty liner body, which is not only environmentally friendly but also economical.
[0012] The second core is made of biodegradable material, thus improving environmental friendliness;
[0013] Both the first and second cores are double or triple layer structures, and are thinner than conventional pads. Attached Figure Description
[0014] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figures 1-5 This utility model provides a technical solution for an ultra-thin and environmentally friendly sanitary pad: its structure includes a pad body 1, the pad body 1 has protective wings 2 on both sides, the pad body 1 has a core cavity 3, the core cavity 3 is surrounded by a barrier strip 4 and a first core 5 is provided inside the core cavity 3, the first core 5 is detachably connected to the core cavity 3;
[0023] The core cavity 3 is provided with a pasting part 6, and a cavity 7 is provided above the pasting part 6. The first core 5 is provided with an adhesive part 8, and an arc-shaped strip 9 is provided on the adhesive part 8. The first core 5 is pasted to the pasting part 6 through the adhesive part 8, and the arc-shaped strip 9 is located in the cavity 7.
[0024] The second core 10 is covered by the first core 5, and the second core 10 is composed of a first absorbing layer 11 and a bottom layer 12, the material of the bottom layer 12 is bio-based plastic, the first core 5 is composed of a surface layer 501, a bamboo charcoal layer 502 and a second absorbing layer 503, the top of the second absorbing layer 503 is an arc structure 504, and the two sides of the second absorbing layer 503 are provided with flow guide strips 505, the flow guide strips 505 are attached to the second core 10, and the arc structure is used to concentrate the menstrual blood in the middle of the first core when the amount of menstrual blood is small.
[0025] For example, in use, the first core 5 is pasted on the sticking part 6 through the adhesive part 8, and the arc-shaped strip 9 is placed in the cavity 7, when the menstrual blood is small in the early or late period, the second absorbing layer 503 on the first core 5 is enough to absorb, so that the first core 5 can be torn off by the arc-shaped strip 9, so that the whole pad main body 1 does not need to be replaced;
[0026] When the amount of menstrual blood is large, the first core 5 is not enough to absorb, and then the flow is guided to the second core 10 through the flow guide strips 505 for absorption.
[0027] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
