Description

Technical Field

[0001] The present invention relates to the technical field of sanitary products, and particularly relates to an artemisia argyi composite chip, a sanitary napkin and a preparation process. Background Art

[0002] A sanitary napkin is a sanitary product designed specifically for women. Currently, sanitary napkins mainly consist of a surface layer, an absorption layer, a leakage prevention layer and a bottom layer. It has good water absorption and water locking capabilities, and is designed to absorb the secretions discharged during a woman's menstrual period to keep the body feeling fresh and comfortable, and reduce the growth of bacteria and fungi, thereby ensuring women's health.

[0003] With the development of related technologies, women's health issues have received increasing attention. Therefore, in more and more sanitary products, functional chips have begun to be added. Functional chips are usually made by combining medical items with fabrics, which can play roles such as antibacterial, health care and odor removal, further ensuring health safety and application comfort.

[0004] The existing invention patent with the authorization announcement number of CN115554031B discloses a bursting bead sanitary napkin, which includes a surface layer, an absorption core layer and a bottom layer. The absorption core layer and the bottom layer are fixedly arranged below the surface layer in sequence. The absorption core layer includes a first absorption core layer and a second absorption core layer. The first absorption core layer is fixedly arranged below the diversion layer, and the second absorption core layer is fixedly arranged below the first absorption core layer. Bursting bead structures are fixedly installed in both the first absorption core layer and the second absorption core layer. The bursting bead structures are divided into a first bursting bead and a second bursting bead. A plurality of first bursting beads are fixedly installed in the first absorption core layer, and a plurality of second bursting beads are fixedly installed in the second absorption core layer.

[0005] In the above technical solution, it integrates antibacterial and anti-inflammatory components in the bursting beads. However, when setting the bursting bead structure, the bursting beads are directly placed in the absorption core layer. Although it can sterilize the menstrual secretions absorbed by the absorption core layer, since the content in the bursting beads will be quickly absorbed by the absorption core layer, it is difficult to act on the human body surface, and it is difficult to achieve the bactericidal effect and health care effect on the human body surface; if the number of bursting beads is increased, especially for thin products, it will cause the problem of excessive product thickness and affect the liquid absorption capacity.

[0045] S10. Set a water-locking surface layer on the annular surface layer, and connect the water-locking surface layer to the annular surface layer and the bottom lining layer to form a sanitary napkin.

[0046] The mugwort composite chip, sanitary napkin and preparation process of the present invention have the following beneficial effects compared with the prior art:

[0047] (1) By setting the bottom film to form a containing area for containing the liquid storage body, and providing a carrier to absorb the mugwort wall-breaking extraction liquid in the liquid storage body. In this way, after the liquid storage body ruptures, the internal mugwort wall-breaking extraction liquid will only be absorbed by the carrier, which limits the diffusion of the mugwort wall-breaking extraction liquid. And the top film is a waterproof and breathable film, and after the mugwort wall-breaking extraction liquid volatilizes, it can pass through the top film and act on the human body to ensure good antibacterial and health care effects on the human body surface, and at the same time, it can prevent menstrual secretions from entering the chip to avoid affecting the volatilization of the mugwort wall-breaking extraction liquid; this structure can also reduce the usage amount of the liquid storage body and the mugwort wall-breaking extraction liquid to avoid affecting the product thickness and reducing the cost.

[0048] (2) In the structure of the present mugwort composite chip, the first absorbent body protrudes towards the top film relative to the connecting body, which is convenient for the connection between the connecting body and the bottom film. At the same time, the top film can be connected to the connecting body through the connecting area, so as to ensure the relative positions of the top film, bottom film and carrier are stable, and avoid the problem of displacement of the carrier due to force.

[0049] (3) In the structure of the present sanitary napkin, the absorbent layer is divided into two absorbent structures of a second absorbent body and a third absorbent body. The second absorbent body corresponds to the mugwort composite chip, and the thickness of the second absorbent body is smaller than that of the third absorbent body. In this way, after placing the mugwort composite chip, it can avoid the increase of the overall thickness of the product, which is beneficial to reducing the product thickness and ensuring the comfort of use.

[0050] (4) In the absorbent layer structure, the second absorbent corresponding to the mugwort leaf composite chip is a water-absorbing factor, and the third absorbent is cotton fiber or a liquid material. Thus, during application, when the liquid storage ruptures, part of the broken-wall extract of mugwort leaf will be absorbed by the first absorbent, while part of the broken-wall extract of mugwort leaf will remain in the accommodation area. When the absorbent layer starts to absorb menstrual secretions, since the water-absorbing factor has a larger expansion rate compared to cotton fiber and the liquid material, the water-absorbing factor will significantly expand to resist the bottom film of the composite chip, thereby enabling the remaining broken-wall extract of mugwort leaf to enter the first absorbent, so as to fully improve the utilization rate. At the same time, the third absorbent has a smaller expansion rate but good water absorption performance, so it can avoid the problem of excessive thickening during application to ensure comfortable use.

[0051] (5) By connecting the annular layer of the sanitary napkin with the top film of the mugwort leaf composite chip, it can be set as an integral structure, which is convenient for covering the mugwort leaf composite chip and the sanitary napkin body. This is beneficial to improving production efficiency and reducing costs.

[0052] (6) By providing a flexible adhesive layer on the wing, the friction of the product against the groin can be reduced, thereby further ensuring the comfort of use. At the same time, the flexible adhesive layer is provided on the wing of the bottom lining layer, and the water-locking surface layer only needs to be provided with an annular wing. This not only ensures the connection with the bottom lining layer but also reduces the material usage and can reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0062] Next, in combination with the implementation manners of the present invention, the technical solutions in the implementation manners of the present invention will be clearly and completely described. Obviously, the described implementation manners are only a part of the implementation manners of the present invention, rather than all of the implementation manners. Based on the implementation manners in the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0063] As Figures 1 - 7 shown, the mugwort composite chip of the present invention includes a bottom film 1, a carrier 2, a top film 3, and a liquid reservoir 4;

[0064] The sanitary napkin of the present invention includes the above-mentioned mugwort composite chip, and further includes an absorption layer 5, a diversion layer 6, an annular layer 7, a bottom lining layer 8, a water-locking surface layer 9, wings 10, a flexible adhesive layer 11, an adhesive layer 12, and a release paper 13;

[0065] As Figure 2 , Figure 3 and Figure 7 shown, the bottom film 1 has a container structure, and an accommodation area 101 is provided inside it; the carrier 2 includes a first absorber 21 and a connector 22. The first absorber 21 is arranged at the opening of the bottom film 1, and the connector 22 is arranged around the first absorber 21. The edge of the bottom film 1 is turned over and adhered to the connector 22; the top film 3 is adhered to the connector 22 and the bottom film 1 to enclose the carrier 2; the liquid reservoir 4 is arranged in the accommodation area 101, and an artemisia argyi wall-broken extraction liquid is arranged in the liquid reservoir 4; the bottom film 1 and the top film 3 are waterproof and breathable membranes;

[0066] In the above structure, the top of the bottom film 1 is open to form a container structure for accommodating the liquid reservoir 4, and the artemisia argyi wall-broken extraction liquid is arranged in the liquid reservoir 4; specifically, the artemisia argyi is broken by fine grinding to achieve the wall-breaking effect, and then steamed and extracted to obtain the extraction liquid; during preparation, materials such as starch and gelatin can be used to make a coating to coat the artemisia argyi wall-broken extraction liquid to form the liquid reservoir 4;

[0067] Afterwards, the liquid storage 4 is placed in a concave mold, and an adhesive is locally coated on the surface of the liquid storage 4 through a roller brush. Then, the first absorbent body 21 of the carrier 2 is adhered to the liquid storage 4 through the adhesive, and then they are placed together in the accommodation area 101 of the bottom film 1. Afterwards, the bottom film 1 is turned over to connect the connecting body 22 of the bottom film 1 and the carrier 2, thereby sealing the liquid storage 4. Finally, a top film 3 is placed on the turned-over edges of the carrier 2 and the bottom film 1 for sealing;

[0068] During application, press this mugwort composite chip to break the liquid storage 4, so that the first absorbent body 21 can absorb the overflowed broken-wall extracted mugwort liquid. Since the top film 3 uses a waterproof and breathable membrane, after the broken-wall extracted mugwort liquid volatilizes, it will pass through the waterproof and breathable membrane to directly act on the human body, thus achieving a good antibacterial and health care effect;

[0069] In this structure, since the broken-wall extracted mugwort liquid can act precisely and will not be absorbed by other absorbent bodies, the amount of the liquid storage can be reduced, thereby avoiding affecting the thickness of the product.

[0070] Specifically, this mugwort composite chip can be used in sanitary products such as sanitary napkins and diapers, and the content liquid of the liquid storage can be selectively changed to suit the application environment.

[0071] As Figure 3 and Figure 7 shown, the first absorbent body 21 protrudes towards the top film 3 relative to the connecting body 22, and a connection area 102 is formed between the first absorbent body 21 and the edge of the bottom film 1; the top film 3 is connected to the connecting body 22 of the carrier 2 through the connection area 102;

[0072] In the structure of this mugwort composite chip as described above, the first absorbent body 21 protrudes towards the top film 3 relative to the connecting body 22, which facilitates the connection between the connecting body 22 and the turned-over edge of the bottom film 1;

[0073] At the same time, a connection area 102 is formed between the turned-over edge of the top film 3 and the bottom film 1. Therefore, the top film 3 can be connected to the connecting body 22 through the connection area 102, thereby ensuring the relative positions of the top film 3, the bottom film 1, and the carrier 2 are stable, avoiding the problem that the carrier 2 is displaced by force, resulting in the inaccurate action of the liquid storage 4, and improving the reliability of the application;

[0074] During specific preparation, the position of the top film 3 corresponding to the connection area 102 is compacted by a mold, so that the top film 3 is attached to the connecting body 22.

[0075] As Figures 5 - 7As shown, the absorbent layer 5 includes a second absorbent body 51, a third absorbent body 52, and an outer wrapping layer 53. Among them, the second absorbent body 51 corresponds to the bottom film 1; the third absorbent body 52 surrounds the second absorbent body 51, the thickness of the third absorbent body 52 is greater than that of the second absorbent body 51, and it surrounds the mugwort leaf composite chip; the outer wrapping layer 53 covers the second absorbent body 51 and the third absorbent body 52, and fits the mugwort leaf composite chip;

[0076] In the above structure, in the sanitary napkin structure, the absorbent layer 5 is divided into two absorbent structures, namely the second absorbent body 51 and the third absorbent body 52. Among them, the second absorbent body 51 corresponds to the mugwort leaf composite chip, and the thickness of the second absorbent body 51 is smaller than that of the third absorbent body 52. In this way, after placing the mugwort leaf composite chip, it can avoid the increase in the overall thickness of the product, which is beneficial to reducing the thickness of the product to ensure the comfort of use.

[0077] Furthermore, the second absorbent body 51 is a water-absorbing factor, the third absorbent body 52 is cotton fiber or a liquid material, and the second absorbent body 51 is in contact with the third absorbent body 52;

[0078] In the above structure, in the absorbent layer 5 structure, the second absorbent body 51 corresponding to the mugwort leaf composite chip is a water-absorbing factor, while the third absorbent body 52 is cotton fiber or a liquid material, which is a conventional material and will not be elaborated too much;

[0079] When it is applied, after the liquid storage 4 ruptures, part of the mugwort leaf broken-wall extract will be absorbed by the first absorbent body 21, while part of the mugwort leaf broken-wall extract will remain in the accommodation area 101. When the absorbent layer 5 starts to absorb menstrual secretions, since the water-absorbing factor has a greater expansion rate compared to cotton fiber and liquid materials, the water-absorbing factor will expand significantly to resist the bottom film 1 of the mugwort leaf composite chip, and the bottom of the bottom film 1 moves towards the first absorbent body 21 of the carrier 2, so that the remaining mugwort leaf broken-wall extract enters the first absorbent body 21 to fully improve the utilization rate;

[0080] At the same time, the third absorbent body 52 has a smaller expansion rate but good water absorption performance, so it can avoid the problem of excessive thickening during application to ensure comfortable application.

[0081] As Figure 7 shown, the diversion layer 6 fits the absorbent layer 5 and surrounds the mugwort leaf composite chip; the annular layer 7 fits the diversion layer 6 and surrounds the mugwort leaf composite chip, and the inner side of the annular layer 7 is connected to the top film 3;

[0082] In the above structure, by setting the diversion layer 6, it can divert menstrual secretions such as menstrual blood, thereby promoting the absorption of the absorbent layer 5 to ensure a dry surface;

[0083] Among them, the annular layer 7 is arranged by fitting the diversion layer 6 and is used to directly contact the human body to ensure the comfort of fitting;

[0084] Furthermore, the inner side of the annular layer 7 is connected to the top film 3; specifically, the annular layer 7 and the top film 3 can be set as an integral structure to ensure the convenience of preparation. In this way, during production, the mugwort leaf composite chip and the absorption layer 5 can be directly sealed simultaneously.

[0085] In such a structure, menstrual secretions will be inhaled through the annular layer 7 and the diversion layer 6. When the absorption layer 5 absorbs menstrual secretions, the third absorber 52 will absorb them first, and at the same time, the mugwort leaf broken-wall extraction liquid absorbed by the first absorber 21 will volatilize.

[0086] As time goes by, the mugwort leaf broken-wall extraction liquid in the first absorber 21 decreases, but the second absorber 51 will start to absorb menstrual secretions and expand, thereby pushing the bottom film 1 to displace towards the first absorber 21. As a result, the mugwort leaf broken-wall extraction liquid remaining in the accommodation area 101 will be absorbed by the first absorber 21 and continue to volatilize, ensuring a continuous antibacterial and health care effect. It has the advantages of reasonable structural layout and good application effect.

[0087] In some embodiments, the third absorber 52 can be provided with a corresponding diversion structure to promote the movement of menstrual secretions towards the second absorber 51, thereby avoiding the situation where the water-locking performance of the third absorber 52 is too good, resulting in the second absorber 51 being unable to function properly.

[0088] Specifically, the diversion structure is set as a diversion cotton strip and passes through the second absorber 51 and the third absorber 52.

[0089] In some embodiments, the liquid storage body 4 is coated with a water-absorbent coating material. Subsequently, during application, when the coating material is squeezed by the second absorber 51 and movement extrusion, the mugwort leaf broken-wall extraction liquid can be transferred to the first absorber 21, thereby playing a role of slow release, avoiding excessive volatilization, making it persistent, and at the same time avoiding irritating the human body.

[0090] As Figure 2 and Figure 7 shown, the bottom lining layer 8 adheres to the side of the absorption layer 5 away from the mugwort leaf composite chip, and the bottom lining layer 8 is a waterproof and breathable membrane; the water-locking surface layer 9 is in a ring structure, the water-locking surface layer 9 is partially adhered to the annular layer 7, and the periphery is connected to the bottom lining layer 8.

[0091] In the above structure, the bottom lining layer 8 is used for leak prevention. It adopts a waterproof and breathable membrane to ensure the breathable performance.

[0092] Among them, the water-locking surface layer 9 is set in a ring structure. In this way, the inner circle of the water-locking surface layer 9 is connected to the annular layer 7, and the outer circle is connected to the bottom lining layer 8, thereby ensuring the water-locking performance and avoiding side leakage problems.

[0093] AsFigure 1 , Figure 2 and Figure 4 As shown in Figure 4 , the flank 10 is provided on the sides of both the bottom lining layer 8 and the water-locking surface layer 9; the flexible adhesive layer 11 is provided on the flank 10 of the bottom lining layer 8; on the flank 10 of the water-locking surface layer 9, a notch 1001 is formed corresponding to the flexible adhesive layer 11, so that the flank 10 of the bottom lining layer 8 forms an annular structure and is integrally heat-melted and connected to the flank 10 on the bottom lining layer 8;

[0094] In the above structure, by providing the flexible adhesive layer 11 on the flank 10, after the flank 10 is adhered to the underwear through the adhesive sheet, the flexible adhesive layer 11 and the flank 10 are folded simultaneously, so that the flexible adhesive layer 11 fits the groin of the human body, which can reduce the friction of the product on the groin and further ensure the use comfort;

[0095] At the same time, the flexible adhesive layer 11 is provided on the flank 10 of the bottom lining layer 8, and only the annular flank 10 needs to be provided on the water-locking surface layer 9, which not only ensures the connection with the bottom lining layer 8, but also reduces the material consumption and can reduce the cost;

[0096] Among them, the annular flank 10 is fully heat-melted and connected to the flank 10 on the bottom lining layer 8 to form a sealing structure surrounding the flexible adhesive layer 11, thereby avoiding the problem of side leakage.

[0097] As Figure 2 shown, the adhesive layer 12 is coated on the side of the bottom lining layer 8 away from the absorption layer 5; the release paper 13 is connected to the bottom lining layer 8 through the adhesive layer 12;

[0098] In the above structure, the adhesive layer 12 is used to bond the release paper 13 to the bottom lining layer 8 for the packaging of the sanitary napkin of the present invention. Specifically, when applied, the release paper 13 can be torn off.

[0099] Specifically, in the sanitary napkin of the present invention, the bottom film 1, the top film 3 and the bottom lining layer 8 are all set as waterproof and breathable membranes, so as to ensure the action effect of the broken-wall extracted liquid of Artemisia argyi and the breathable effect; the specific material is not limited. For example, it can be prepared from materials such as polyethylene. The bottom film 1 and the top film 3 should ensure good waterproof effect and do not affect the escape of gas molecules volatilized from the broken-wall extracted liquid of Artemisia argyi;

[0100] Among them, the annular surface layer 7 can be made of pure cotton material to ensure the comfort of fitting during application.

[0101] The preparation process of the sanitary napkin of the present invention includes the following steps:

[0102] S1. Prepare the gel material, convey and solidify it through a cooling roller, then the gel material is conveyed through a shaping roller. During the conveying process, the gel material is heated and the broken-wall extracted liquid of Artemisia argyi is injected, and finally the gel material is solidified again to form the liquid storage body 4;

[0103] S2. Locally coat an adhesive on the surface of the liquid storage 4, and bond the liquid storage 4 to the connecting body 22 of the carrier 2 through the adhesive;

[0104] S3. Wrap the liquid storage 4 with the bottom film 1 and form a flanging to abut against the carrier 2;

[0105] S4. Connect the mugwort composite chip with the absorbent layer 5 and make the mugwort composite chip correspond to the second absorbent body 51;
