Abstract
Description
Technical Field
[0001] This utility model relates to a disposable absorbent article, and more particularly to a sanitary napkin with wings. Background Technology
[0002] Personal hygiene products can be categorized into disposable and non-disposable products based on their usage frequency. Absorbent hygiene products fall under the disposable category and primarily include feminine hygiene products, baby hygiene products, and adult incontinence products. Sanitary napkins are a type of feminine hygiene product mainly used to absorb menstrual blood, helping to maintain cleanliness and comfort. They are typically made of soft absorbent material and usually consist of a leak-proof bottom layer, an absorbent core, and a soft top layer, designed to conform to the curves of a woman's body; some also have wings to prevent side leakage.
[0003] Currently available sanitary napkins often suffer from poor fixation during use, easily shifting and causing wrinkles and folds. This not only increases the risk of side leakage but may also lead to discomfort during wear, affecting the user experience. Utility Model Content
[0004] The main purpose of this utility model is to overcome the shortcomings of the poor fixation effect of existing sanitary napkins and to provide a disposable absorbent article, especially a sanitary napkin with wings.
[0005] The present invention adopts the following technical solution:
[0006] A disposable absorbent article having a transverse axis X and a longitudinal axis Y, the disposable absorbent article comprising a liquid-permeable top layer, a liquid-impermeable bottom layer, and an absorbent core between the liquid-permeable top layer and the liquid-impermeable bottom layer, the disposable absorbent article being sequentially divided into a front zone, a middle zone, and a rear zone along the longitudinal direction, the disposable absorbent article further comprising a wing extending in the transverse direction of the middle zone, characterized in that: the wing comprises at least one main wing, at least one first auxiliary wing, and at least one second auxiliary wing, and the non-skin side of the wing is provided with a fixing area.
[0007] Specifically, the first auxiliary wing extends along a first imaginary line and has a first angle between the first imaginary line and the transverse axis X, and the second auxiliary wing extends along a second imaginary line and has a second angle between the second imaginary line and the transverse axis X.
[0008] Specifically, the first angle of the first auxiliary winglet and the second angle of the second auxiliary winglet are 10 degrees to 60 degrees, respectively, and the second angle is not less than the first angle.
[0009] Specifically, the wing includes a main wing extending in a first lateral direction, a first auxiliary wing extending in a second lateral direction opposite to the first lateral direction, and a second auxiliary wing extending in the second lateral direction.
[0010] Specifically, the maximum lateral width of the main wing, the first auxiliary wing, and the second auxiliary wing is not less than 50% of the lateral width of the central region of the absorption core.
[0011] Specifically, the first auxiliary wing and the second auxiliary wing have a maximum longitudinal length, the main wing has a maximum longitudinal length, and the maximum longitudinal length of the auxiliary wing is not less than the maximum longitudinal length of the main wing.
[0012] Specifically, the wing includes a pair of main winglets, a pair of first auxiliary winglets, and a pair of second auxiliary winglets that are symmetrically arranged and extend in two lateral directions.
[0013] Specifically, the maximum lateral width of the main wing, the first auxiliary wing, and the second auxiliary wing is no greater than 50% of the lateral width of the central region of the absorption core.
[0014] As can be seen from the above description of this utility model, the beneficial effects of this utility model are as follows:
[0015] Based on the main wing piece, first and second auxiliary wing pieces with a certain degree of inclination relative to the transverse axis are set. They are used in conjunction with the fixing area to form a joint positioning at the top, middle and bottom, increasing the area of the wing piece fixed to the surface of the underwear, ensuring the fixing effect of the wing piece, and preventing the sanitary napkin from shifting, wrinkling or folding, and further improving the leak-proof performance of the sanitary napkin. Among them, the second auxiliary wing piece has a larger area and a larger inclination angle, which enhances the adhesion strength to the back area of the sanitary napkin and further strengthens the bond between the sanitary napkin and the underwear.

Detailed Implementation
[0023] The present invention will be further described below through specific embodiments.
[0024] like Figure 1-5 As shown, a disposable absorbent article has a transverse axis X and a longitudinal axis Y. The disposable absorbent article includes a liquid-permeable surface layer 11, a liquid-impermeable bottom layer 12, and an absorbent core 13 between the liquid-permeable surface layer and the liquid-impermeable bottom layer. The disposable absorbent article is divided into a front zone A, a middle zone B, and a rear zone C in the longitudinal direction. The disposable absorbent article also includes a wing 14 extending in the transverse direction of the middle zone.
[0025] Figure 1-2 This is the first embodiment of the present utility model.
[0026] The wing 14 includes at least one main winglet 141, at least one first auxiliary winglet 142, and at least one second auxiliary winglet 143. The first auxiliary winglet 141 extends along a first imaginary line D and has a first angle α1 relative to the first imaginary line D with respect to the lateral axis X, where the first angle α1 is between 10 and 60 degrees. The second auxiliary winglet 143 extends along a second imaginary line E and has a second angle α2 relative to the second imaginary line E with respect to the lateral axis X, where the second angle α2 is between 10 and 60 degrees. The first auxiliary winglet 142 and the second auxiliary winglet 143 are tilted to a certain degree relative to the lateral axis X. In this embodiment, the first auxiliary winglet 142 is partially projected onto the front region A after folding, and the second auxiliary winglet 143 is partially projected onto the rear region C after folding. In some embodiments, the second angle α2 is not less than the first angle α1, that is, the second auxiliary winglet 142 has a larger tilt angle.
[0027] In this embodiment, the wing 14 includes a main wing 141 extending in a first lateral direction, a first auxiliary wing 142 extending in a second lateral direction opposite to the first lateral direction, and a second auxiliary wing 143 extending in the second lateral direction opposite to the first lateral direction.
[0028] In this embodiment, the maximum lateral width W141 of the main wing, the maximum lateral width W142 of the first auxiliary wing, and the maximum lateral width W143 of the second auxiliary wing are all not less than 50% of the lateral width W13 of the central region of the absorption core.
[0029] In this embodiment, the first auxiliary wing 142 and the second auxiliary wing 141 each have a first farthest end f1 and a second farthest end f2, and the vertical longitudinal length between the first farthest end f1 and the second farthest end f2 is the maximum longitudinal length L142 of the auxiliary wing. The main wing 141 has the maximum longitudinal length L141 of the main wing, and the maximum longitudinal length L142 of the auxiliary wing is not less than the maximum longitudinal length L141 of the main wing, so as to ensure the area of the wing fixed to the surface of the underwear.
[0030] A fixing area 15 is provided on the non-skin side of the wing 14. Adhesive material is provided in the fixing area 15, which secures the wing to the underwear when folded under the absorbent core 13 during use. The shape of the fixing area 16 is not limited. In this embodiment, the fixing areas at the first auxiliary wing 142 and the second auxiliary wing 143 are rectangular with a certain angle of inclination, further enhancing the fixing effect.
[0031] Based on the main wing piece 141, a first auxiliary wing piece 142 and a second auxiliary wing piece 143 with a certain degree of inclination relative to the transverse axis X are provided. They are used in conjunction with the fixing area 15 to form a joint positioning of the upper, middle and lower parts, increase the area of the wings fixed to the surface of the underwear, ensure the fixing effect of the wings, avoid the sanitary napkin from displacement, wrinkles, folds and other phenomena, and further improve the leak-proof performance of the sanitary napkin.
[0032] Figure 3-5 This is the second embodiment of the present invention.
[0033] The wing 14 includes a pair of main wing pieces 141, a pair of first auxiliary wing pieces 142 and a pair of second auxiliary wing pieces 143 that are symmetrically arranged and extend in two lateral directions. By setting the symmetrically distributed wings, the adhesive force of the wings on both sides is balanced, which further prevents the sanitary napkin from shifting.
[0034] The maximum lateral width W141 of the main wing, the maximum lateral width W142 of the first auxiliary wing, and the maximum lateral width W143 of the second auxiliary wing are not greater than 50% of the lateral width W13 of the central region of the absorption core.
[0035] The above are only a few specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
