A sanitary napkin with retractable side wings

Abstract

This application relates to a sanitary napkin with retractable side wings, and pertains to the technical field of sanitary napkins. It includes an absorbent portion with symmetrically arranged side wings. At least one of the side wings has an extension portion that is stretchable. In the stretched state, the two side wings can connect to each other. This application has the advantage that the side wings are less likely to detach from the underwear, thus reducing the protective effect.

Description

Technical Field

[0001] This application relates to the technical field of sanitary napkins, and in particular to a sanitary napkin with retractable side wings. Background Technology

[0002] Sanitary napkins are made of a polymer and polymer composite paper formed from cotton, non-woven fabric, pulp, or a combination of these materials. They are primarily used as hygiene products for women during menstruation. They consist of three layers from the inside out: a top layer, an absorbent core, and a bottom layer. Two side wings are designed to prevent leakage. To use, first tear off the middle paper strip, then stick the adhesive side to the middle of the underwear, and finally attach the two side wings to the underwear.

[0003] Existing sanitary napkins typically have their side wings attached to underwear during use. However, during exercise, the side wings can easily detach from the underwear, resulting in poor protective performance. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, one of the purposes of this application is to provide a sanitary napkin with retractable side wings, which has the advantage that the side wings are not easy to fall off the underwear, thus reducing the protective effect.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A sanitary napkin with retractable side wings includes an absorbent portion, on which side wings are symmetrically arranged, and at least one of the side wings is provided with an extension portion, which is stretchable, and in the stretched state, the two side wings can be connected to each other.

[0007] By adopting the above technical solution, the presence of the extension allows the two side wings to connect with each other during use, thus effectively reducing the probability of the side wings falling off.

[0008] In a preferred embodiment, the present application may be further configured such that the extension includes a connecting line and a folded area, the connecting line connecting the two ends of the folded area, thereby forming folds in the folded area.

[0009] By adopting the above technical solution, when it is necessary to extend the side wings, the side wings are pulled to break the connecting lines, thereby allowing the folded area to be unfolded.

[0010] In a preferred embodiment, this application may be further configured such that: both of the said side wings are provided with the said extensions, and the side wings are also provided with connecting portions for interconnection.

[0011] By adopting the above technical solution, extensions are provided on both side wings, so that the connection between the two side wings is located in the middle position during use.

[0012] In a preferred embodiment, the extension may be further configured such that the extension includes a waterproof cavity, the waterproof cavity having an expansion element for absorbing liquid.

[0013] By adopting the above technical solution, the presence of the expansion element inside the waterproof cavity during use allows the waterproof cavity to expand, thereby enabling the absorbent part to fit more closely to the human body.

[0014] In a preferred embodiment, the present application may be further configured such that: the waterproof cavity includes a bottom membrane and a top membrane, both of which are made of waterproof material, and the length of the bottom membrane is less than the length of the top membrane.

[0015] By adopting the above technical solution, since the length of the bottom film is less than the length of the top film, when the expansion component expands during use, the side closer to the absorbent core is lifted to a higher height, thereby achieving the effect of making the absorbent part fit the human body more closely.

[0016] In a preferred embodiment, the present application may be further configured such that: the connecting line is located inside the waterproof cavity, the connecting line is hollow, and the connecting line is filled with liquid.

[0017] By adopting the above technical solution, when the connecting wire is broken during use, the liquid inside the connecting wire will come into contact with the expansion component, thereby achieving the effect of absorbing water and expanding.

[0018] In a preferred embodiment, the waterproof cavity can be further configured such that it gradually expands from the center of the absorbent portion toward the edge of the absorbent portion.

[0019] By adopting the above technical solution, the two side wings can form a high-on-the-sides-and-low-in-the-middle effect during use, which makes the absorbent part curved, thus making the fit with the human body better.

[0020] In a preferred embodiment, this application may be further configured such that the side wing is also provided with adhesive for connecting to the underwear.

[0021] By adopting the above technical solution, the effect of wing detachment is further reduced during use. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 and Figure 2 The present application discloses a sanitary napkin with retractable side wings 2, which includes an absorbent part 1, side wings 2 symmetrically arranged on the absorbent part 1, and an extension part 3 arranged on at least one side wing 2. In this embodiment, both side wings 2 are provided with extension parts 3, and the extension parts 3 are stretchable.

[0027] The extension 3 includes a connecting line 5 and a pleated area. The pleated area includes a bottom membrane 32 and a top membrane 31, both of which are made of waterproof material. The length of the bottom membrane 32 is less than the length of the top membrane 31. A waterproof cavity 33 is formed between the bottom membrane 32 and the top membrane 31 to accommodate the connecting line 5. The waterproof cavity 33 gradually expands from the middle of the absorbent portion 1 towards its edge. An expansion member 4 is also provided inside the waterproof cavity 33. The connecting line 5 is hollow and filled with liquid. The connecting line 5 can be made of a flexible waterproof material, such as plastic. The expansion member 4 can be absorbent paper. The expansion member 4 is strip-shaped and fixed at intervals on the bottom membrane 32, and its thickness gradually increases along the direction close to the absorbent portion 1. A weak section is also provided on the connecting line 5, located at one end of the connecting line 5 near the absorbent portion 1. The tensile strength of the weak section is less than that of other parts of the connecting line 5. The two ends of the connecting line 5 are connected to the two ends of the waterproof cavity 33, causing the waterproof cavity 33 to pleat.

[0028] The two sides of the wing 2 are also provided with adhesive at their close ends, and adhesive is also provided on the wing 2 for bonding with underwear.

[0029] The implementation principle of this embodiment is as follows: During use, the side wings 2 are unfolded and the extension part 3 is pulled, causing the connecting line 5 to break at the weak point. Then, the side wings 2 are flipped over so that the side wings 2 are attached to the underwear. The side wings 2 are fixed to the inside with adhesive. The overlapping parts of the two side wings 2 are connected to each other with adhesive. After the connecting line 5 breaks, the liquid inside the connecting line 5 is first absorbed and expanded by the thicker absorbent paper. Since the length of the bottom film 32 is less than the length of the top film 31, under the action of the expansion member 4, the two side wings 2 can form a high-on-the-sides and low-on-the-middle effect, which makes the absorbent part bend, thereby making the fit with the human body better.

[0030] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
