Description

Technical Field

[0001] This application relates to the technical field of sanitary products, and particularly to a tampon. Background Art

[0002] A tampon, also known as a vaginal suppository, has an absorbent core mainly made of cotton, rayon, or a mixture of these two materials, with a cotton string (pull cord) attached to the end. It is inserted into the vagina to absorb menstrual blood, and after being filled with menstrual blood, the absorbent core is pulled out through the pull cord. Currently, the absorbent core of tampons on the market generally has a cylindrical or fan-shaped shape, which does not fit well with the vaginal structure, and it is easy to cause certain discomfort after the absorbent core absorbs a certain amount of menstrual blood. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a tampon that can reduce the discomfort of the absorbent core in the body.

[0004] A tampon includes an absorbent core and a pull cord. The pull cord is disposed at one end of the absorbent core. The absorbent core includes multiple layers of sheets, and the multiple sheets are stacked in an irregular shape around an axis from the inside to the outside. From the end of the absorbent core close to the pull cord to the other end, the outer shape of the absorbent core gradually expands.

[0005] In one embodiment, the absorbent core includes one or more sheet-like substrates, and the sheet-like substrates are formed into multiple layers of sheets after being folded and pressed.

[0006] In one embodiment, the central region of the sheet-like substrate is formed into the smaller end of the outer shape of the absorbent core after being folded and pressed.

[0007] In one embodiment, the sheet-like substrate includes an absorbent layer and a liquid-permeable layer. The liquid-permeable layer is disposed on one side of the absorbent layer. The friction coefficient of the liquid-permeable layer is less than that of the absorbent layer. After the sheet-like substrate is folded and pressed, the outermost layer of the absorbent core is the liquid-permeable layer.

[0008] In one embodiment, the liquid-permeable layer is made of antibacterial non-woven fabric.

[0009] In one embodiment, the surface and interior of the absorbent core are provided with multiple curved grooves.

[0010] In one embodiment, the absorbent core includes one or more sheet-like substrates, and the sheet-like substrates are formed into multiple layers of sheets after being folded and pressed. The grooves are formed at the edges and folding parts of the sheet-like substrates.

[0011] In one embodiment, the tampon further includes a leakage prevention cup disposed at the smaller end of the absorbent core. The end of the absorbent core extends into the leakage prevention cup and is fixedly connected to the leakage prevention cup. The drawstring is fixedly connected to the absorbent core or the leakage prevention cup.

[0012] In one embodiment, the leakage prevention cup is conical.

[0013] In one embodiment, the leakage prevention cup is made of a soft film or silicone material.

[0014] Compared with the prior art, for the tampon provided in this application, the absorbent core is arranged such that from the end close to the drawstring to the other end, the outer shape of the absorbent core gradually expands. Since the internal structure of the vagina is wider at the top and narrower at the bottom, the outer shape of the absorbent core is adapted to the shape of the vaginal structure. After the absorbent core absorbs a certain amount of menstrual blood, it expands into a shape that is larger at the top and smaller at the bottom, without locally squeezing the vaginal wall, greatly reducing the discomfort of the absorbent core in the body. Since the absorbent core includes multiple layers of sheet bodies, the multiple sheet bodies are stacked around an axis in an irregular shape from the inside to the outside, so that the absorbent core can more easily absorb menstrual blood. Moreover, since the outer shape of the absorbent core is adapted to the shape of the vaginal structure, the absorbent core can fit against the vaginal wall, thereby reducing the risk of menstrual blood leakage. In addition, after being filled with menstrual blood, this absorbent core that is larger at the top and smaller at the bottom is also easier to pull out. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figure 1The present application provides a tampon, including an absorbent core 10 and a drawstring 20, wherein the drawstring 20 is disposed at one end of the absorbent core 10. The absorbent core 10 includes a multi-layer sheet 11, which is stacked in an irregular shape from the inside to the outside around an axis. It is understandable that the "axis" is not a real line, but a name defined to clearly define the stacking method of the sheet 11. From one end of the absorbent core 10 close to the drawstring 20 to the other end, the shape of the absorbent core 10 gradually expands. Since the interior of the vagina is a structure that is wide at the top and narrow at the bottom, the shape of the absorbent core 10 of the tampon provided by the present application is adapted to the shape of the vaginal structure. After the absorbent core 10 absorbs a certain amount of menstrual blood, it expands into a shape that is large at the top and small at the bottom, and will not locally squeeze the inner wall of the vagina, greatly reducing the discomfort of the absorbent core 10 in the body. Since the absorbent core 10 includes multiple layers of sheets 11, which are stacked in irregular shapes from inside to outside around an axis, the absorbent core 10 is easier to absorb menstrual blood, and since the shape of the absorbent core 10 is adapted to the shape of the vaginal structure, the absorbent core 10 can fit the inner wall of the vagina, thereby reducing the risk of menstrual blood leakage. In addition, after absorbing the menstrual blood, the absorbent core 10 with a larger top and a smaller bottom is also easier to pull out.

[0026] Furthermore, the absorbent core 10 includes one or more sheets of sheet substrates 12, which are folded and pressed to form a multi-layer sheet 11. Since the multi-layer sheet 11 is formed by folding and pressing the sheet substrate 12, the folded portion of the sheet substrate 12 is equivalent to the edge of the sheet 11. A sheet substrate 12 can be folded and pressed to form multiple sheets 11, and the edges of adjacent sheets 11 are connected, and the connected edges are the folds of the sheet substrate 12. This embodiment uses one or more sheets of sheet substrates 12 as raw materials, and after folding and pressing, the absorbent core 10 product can be obtained, which has a simple structure and a simple processing method. Figure 2 As shown, the absorbent core 10 includes two sheet substrates 12, which are arranged in a cross shape. The central areas of the two sheet substrates 12 are fixed by a fixing line 40, and the remaining parts are folded upward and pressed by a mold to obtain a product as shown in FIG. Figure 1 An absorbent core 10 comprising a multi-layer sheet 11 is shown.

[0027] In this embodiment, the central area of the sheet substrate 12 is folded and pressed to form the end of the absorbent core 10 with a smaller shape. In this way, during processing, by fixing the central area of the sheet substrate 12 and then pressing the remaining part, the absorbent core 10 with one end closed and the other end gradually expanded can be obtained, and the processing method is simple.

[0028] See also Figure 3The sheet substrate 12 includes an absorbent layer 121 and a liquid-permeable layer 122. The liquid-permeable layer 122 is disposed on one side of the absorbent layer 121. The friction coefficient of the liquid-permeable layer 122 is less than that of the absorbent layer 121. After the sheet substrate 12 is folded and pressed, the outermost layer of the absorbent core 10 is the liquid-permeable layer 122. In this way, the absorption of menstrual blood can be ensured, and the friction between the absorbent core 10 and the inner wall of the vagina can be reduced, thereby reducing the friction pain when putting in or taking out the absorbent core 10, and it can also be used during periods of light menstruation. It can be understood that since the sheet substrate 12 is formed into a multi-layer sheet 11 after being folded and pressed, part of the liquid-permeable layer 122 will also be folded into the absorbent core 10. In other words, the interior of the absorbent core 10 includes both the absorbent layer 121 and the liquid-permeable layer 122. As long as the outermost layer of the absorbent core 10 is the liquid-permeable layer 122, it will be sufficient. Taking the figure as an example, during processing, the two sheet substrates 12 are folded upward and gathered together. Before folding and pressing, the liquid-permeable layer 122 of the sheet substrate 12 faces downward, so that after folding and pressing, it can be ensured that the outermost layer of the absorbent core 10 is the liquid-permeable layer 122.

[0029] The absorption layer 121 is mainly made of organic cotton, has good skin-friendliness and high absorption capacity.

[0030] Furthermore, the liquid-permeable layer 122 is made of antibacterial nonwoven fabric, so as to prevent bacteria from growing and purify the odor caused by menstrual blood.

[0031] See also Figure 1 Furthermore, a plurality of curved grooves 13 are provided on the surface and inside of the absorbent core 10. In the prior art, linear grooves are usually pressed on the surface of the absorbent core, and menstrual blood will flow down along the grooves, thereby posing a certain risk of leakage. In this embodiment, by setting the grooves 13 to be curved, the flow path of menstrual blood is increased, the absorbency of the absorbent core 10 is improved, and the risk of menstrual blood leakage is reduced.

[0032] In this embodiment, the absorbent core 10 includes one or more sheet substrates 12, which are folded and pressed to form a multi-layer sheet 11, and grooves 13 are formed at the edges and folded portions of the sheet substrate 12. In this way, the grooves 13 can be directly obtained by pressing the sheet substrate 12, so that there is no need to specially design a mold, thereby reducing the mold development cost.

[0033] Further, in one embodiment, see Figure 1 The tampon also includes a leak-proof cup 30, which is arranged at the end of the absorbent core 10 with a smaller shape, the end of the absorbent core 10 extends into the leak-proof cup 30 and is fixedly connected to the leak-proof cup 30, and the drawstring 20 is fixedly connected to the absorbent core 10 or the leak-proof cup 30. In this way, by setting the leak-proof cup 30, leakage can be avoided during use, reducing the user's concerns about leakage during use.

[0034] Further, the leak - proof cup 30 is conical. The shape of the leak - proof cup 30 is adapted to the shape of the end of the absorbent core 10, and it is easy to be fixed at the end of the absorbent core 10. Further, the leak - proof cup 30 can be adhered to the end of the absorbent core 10 by glue.

[0035] In one embodiment, the leak - proof cup 30 is made of a soft film or silicone material. In this way, the leak - proof cup 30 has a soft texture, avoiding a foreign body sensation when placed in the vagina.

[0036] Of course, in other embodiments, the tampon may not include a leak - proof cup.

[0037] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0038] The above - described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
