Description

Technical Field

[0001] The invention relates to the field of sanitary products, in particular to an integrated wrapped side leakage-proof sanitary napkin. Background Art

[0002] As society's awareness of women's physiological health increases, the market demand for sanitary napkins is increasing. Traditional sanitary napkins have certain deficiencies in air permeability, which often easily cause discomfort to the wearer. Especially in a hot and humid environment, it may cause skin problems and odor. Developing a sanitary napkin with good air permeability has become a technical problem that needs to be solved urgently.

[0003] In order to solve the above technical problems, for example, publication number CN105796247A discloses a refreshing and breathable sanitary napkin, which specifically discloses that it includes a bottom waterproof layer and an upper water storage layer, the upper water storage layer is arranged above the bottom waterproof layer, a breathable layer is arranged above the upper water storage layer, a soft layer is arranged above the breathable layer, leak-proof wings are respectively arranged on both sides of the upper water storage layer, the breathable layer is non-woven fabric or mesh fabric, the soft layer is a thin cotton layer, and the edges on both sides of the breathable layer and the soft layer are connected.

[0004] However, the above-mentioned sanitary napkin still has some shortcomings. For example, the breathable layer is a non-woven fabric or a mesh fabric, which forms an exchange between the internal air of the sanitary napkin and the external air through the breathable properties of the material itself or through the mesh structure, so as to achieve the breathable property. However, when menstrual blood flows into the upper water storage layer through the breathable layer, since the menstrual blood has a certain viscosity, it is easy to cause the mesh to be blocked when passing through the breathable layer, that is, the structure of the mesh cannot make the sanitary napkin have excellent breathability; in addition, the breathable layer is facing the skin side. In actual use, the breathable layer is squeezed when worn and will be close to the skin side, which means that there is no space for ventilation inside, and the breathability is also poor.

[0005] Therefore, it is necessary to make further improvements to the prior art. Summary of the invention

[0006] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide an integrated wrapped sanitary napkin for preventing side leakage, which is extended and folded in the width direction of the first absorbent body through the breathable surface layer and is sealed through the sealing of the third end, so that it can completely cover the first absorbent body; at the same time, through the provision of the first breathable channel and the waterproof breathable membrane, it has breathable properties while preventing the occurrence of side leakage of menstrual blood.

[0007] In order to achieve the above object, the technical solution of the present invention is:

[0008] A one-piece covered sanitary napkin for preventing side leakage comprises a sanitary napkin body, wherein the sanitary napkin body comprises a water-permeable surface layer, a first absorbent body, a water-impermeable bottom layer and a waterproof breathable membrane; the waterproof breathable membrane is coated on the lower end and the side end of the first absorbent body to prevent the risk of side leakage; the water-permeable surface layer has a first end extending along the width direction of the first absorbent body and coated on the first absorbent body and the surface of the waterproof breathable membrane, and the two ends of the first end meet at the lower end of the waterproof breathable membrane after extension and are joined to each other by heat pressing; it also has a second end joined to the end of the first end and extending to the outside of the first absorbent body, and there is a gap between the second end and the first end to form a first air permeable channel that can be laterally breathable; the water-permeable surface layer also has two third ends extending along the length direction of the first absorbent body, and the third ends are respectively sealed by heat pressing; the water-impermeable bottom layer is fittedly arranged at the bottom end of the water-permeable surface layer.

[0009] Furthermore, a bent portion bent downward is formed at the end of the first end, and end surfaces of the two bent portions are adhered to each other and connected to each other by heat pressing.

[0010] Furthermore, one end of the second end is connected to the bent portion, and the other end thereof extends horizontally toward the outside of the first absorbent body.

[0011] Furthermore, the first end, the second end and the third end are integrally formed.

[0012] Furthermore, the first absorbent body and the waterproof breathable membrane are both fixedly connected to the water-permeable surface layer by means of adhesive stickers.

[0013] Furthermore, the integrated side leakage preventing sanitary napkin further comprises a second absorbent body provided in the sanitary napkin body, and the second absorbent body is arranged above the first absorbent body.

[0014] Furthermore, a liquid permeation channel is provided between the first absorbent body and the second absorbent body.

[0015] Furthermore, a second air permeable channel is provided outside the water-permeable surface layer and between the first absorbent body and the second absorbent body.

[0016] The beneficial effects of the present invention are:

[0017] (1) The present invention extends and folds the breathable surface layer along the width direction of the first absorbent body, so that when the breathable surface layer covers the first absorbent body, a breathable channel that is laterally connected to the outside of the first absorbent body is formed at the bottom of the first absorbent body, so that air can flow into the bottom of the first absorbent body through the breathable channel and exchange with the external air to keep the sanitary napkin dry, thereby improving the comfort when wearing.

[0018] (ii) The present invention covers the bottom and side ends of the first absorbent body with a waterproof breathable film, thereby preventing the side leakage of menstrual blood while also having better breathability. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The invention is further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only exemplary and does not limit the protection scope of the invention.

[0028] Embodiment 1:

[0029] like Figure 1-3 As shown, an integrated wrapped anti-side leakage sanitary napkin includes a sanitary napkin body 1, and the sanitary napkin body 1 includes a permeable surface layer 2, a first absorbent body 3, an impermeable bottom layer 4 and a waterproof breathable membrane 5; in this embodiment, when the permeable surface layer 2 is in use, it contacts the skin of the human body, and menstrual blood can penetrate through the permeable surface layer 2 into the first absorbent body 3; the first absorbent body 3 is made of antibacterial material, which can effectively play a bactericidal role; in addition, medicine can be arranged inside it, and it can also be used in medical treatment; the impermeable bottom layer 4 has a waterproof property, which can prevent menstrual blood from leaking through the impermeable bottom layer 3; the waterproof breathable membrane 5 can also be breathable while preventing menstrual blood from penetrating.

[0030] like Figure 3 As shown, the waterproof breathable membrane 5 covers the lower end and the side end of the first absorbent body 3 to prevent the risk of side leakage.

[0031] like Figure 3 As shown, the water-permeable surface layer 2 has a first end 21 extending along the width direction of the first absorbent body 3 and covering the surface of the first absorbent body 3 and the waterproof breathable membrane 5. The two ends of the first end 21 meet at the lower end of the waterproof breathable membrane 5 after extension and are joined to each other by heat pressing. Specifically, a bending portion 24 bent downward is formed at the end of the first end 21, and the end faces of the two bending portions 24 are attached to each other and connected to each other by heat pressing. Among them, since the thickness of the water-permeable surface layer 2 is relatively thin, when connected to each other, in order to make the connection more stable, the end faces of the bending portions 24 are stacked and connected to each other by heat pressing. Through the above arrangement, the water-permeable surface layer 2 can cover the surface of the first absorbent body 3 and the waterproof breathable membrane 5.

[0032] like Figure 3 As shown, it also has a second end 22 connected to the end of the first end 21 and extending to the outside of the first absorbent body 3, and there is a gap between the second end 22 and the first end to form a first ventilation channel 6 that can be ventilated laterally; specifically, one end of the second end 22 is connected to the bending portion 24, and the other end thereof extends horizontally to the outside of the first absorbent body 3. In this embodiment, the first ventilation channel 6 can allow air to flow from the side of the toilet body 1 to the bottom of the first absorbent body 3, so that the integrated wrapped anti-side leakage sanitary napkin has better air permeability. Specifically, when in use, after the toilet body 1 contacts the skin side, it presents a certain arc shape. At this time, the first ventilation channels 6 located on both sides of the toilet body 1 are affected by the tension after bending, and the openings of the first ventilation channels 6 will form an open state, which makes it easier for air to enter the bottom of the first absorbent body 3 through the first ventilation channel 6 when worn.

[0033] like Figure 3 As shown, the water-permeable surface layer 23 also has two third ends 23 extending along the length direction of the first absorbent body 3, and the third ends 23 are respectively sealed by heat pressing. In the present embodiment, the third end 23 is extended in the length direction of the first absorbent body 2 by the first end 21 and the second end 22 in a flattened state, and is sealed by heat pressing after being extended, so that the first absorbent body 3 can be sealed in the water-permeable surface layer 2.

[0034] like Figure 3 As shown, the water-impermeable bottom layer 4 is arranged in a close relationship with the bottom end of the water-permeable surface layer 2. Through the above arrangement, the water-impermeable bottom layer 4 can prevent leakage of menstrual blood.

[0035] In order to make the first absorbent body 3 more stably fixed, the first absorbent body 3 and the waterproof breathable membrane 4 are fixedly connected to the water-permeable surface layer 2 by means of adhesive tape.

[0036] In this embodiment, the first end 21, the second end 22 and the third end 23 are integrally formed, wherein the first end 21, the second end 22 and the third end 23 are all folded or extended in the shape of the first absorbent body 3.

[0037] Embodiment 2:

[0038] like Figure 4 As shown, the integrated wrapped side leakage prevention sanitary napkin further includes a second absorbent body 7 in the sanitary napkin body 1, and the second absorbent body 7 is arranged above the first absorbent body 3. Through the above arrangement, the integrated wrapped side leakage prevention sanitary napkin has a better anti-leakage effect.

[0039] like Figure 4 As shown, a liquid permeation channel 8 is further provided between the first absorbent body 3 and the second absorbent body 7. Through the above arrangement, after the second absorbent body absorbs the menstrual blood, the menstrual blood can flow back into the first absorbent body 3 through the liquid permeation channel 8, thereby absorbing and storing a larger amount of menstrual blood.

[0040] like Figure 4 As shown, a second air permeable channel 9 is further provided outside the water permeable surface layer 2 and between the first absorbent body 3 and the second absorbent body 7. With the above arrangement, the integrated wrapped side leakage prevention sanitary napkin has better air permeability.

[0041] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
