Description

Title of the invention: Menstrual protection textile underwear

[0001] The technical context of the present invention is that of periodic protections, and more particularly of underwear for menstruating persons making it easier to use periodic protections. More particularly, the invention relates to a textile menstrual protection underwear.

[0002] Most menstruating people use periodic protections at the beginning of each of their cycles, for the absorption of their menstrual flow. In the state of the art, periodic protections of the sanitary napkin type are known, intended to be placed inside the underwear of the user. To ensure good intimate hygiene and absorb menstrual flow, the sanitary napkin is made of absorbent materials. These absorbent materials are intended to provide a certain comfort to the user while protecting their underwear. There are disposable models of sanitary napkins and washable models.

[0003] Although easy to use compared to other menstrual protection products, such as intravaginal protection, disposable sanitary napkins have disadvantages. Chemicals are used to produce them: disposable sanitary napkins contain residues that can be toxic to the user and can cause redness, itching, allergies, or similar. Disposable sanitary napkins contribute to generating significant volumes of non-recyclable waste, considered particularly polluting. Disposable sanitary napkins are also a hygiene consumable that generates recurring financial expenses.

[0004] Washable sanitary towels help to resolve some of these drawbacks, particularly by being reusable and generally having a more environmentally friendly composition. They help to reduce the amount of waste produced and are, ultimately, more economical for the user.

[0005] As is known, a washable sanitary napkin comprises a fastening system intended to position said sanitary napkin relative to the user's underwear. However, unlike a disposable sanitary napkin which is fixed by an adhesive, the washable sanitary napkin is non-adherent and can slide relative to the underwear associated with it. It is understood that optimal positioning preventing leaks is not guaranteed for the washable sanitary napkin.

[0006] Women's underwear with an absorbent crotch for bodily fluids is also known. These underwear are commonly called men's panties. trowels. These menstrual panties incorporate absorbent materials into their structure designed to absorb menstrual flow and prevent leaks. Menstrual panties are reusable, like washable sanitary napkins. However, they provide greater comfort to the user. Indeed, the absorbent materials are fixed in this underwear since they are integrated solidly at the crotch.

[0007] A disadvantage of these menstrual panties lies in the fact that they are worn by the user for a long time. Indeed, in a conventional mode of use, the menstrual panties are changed in the morning when the user gets dressed and in the evening before going to bed. For practical reasons, it is rare to change menstrual panties during the day. A user wishing to renew their periodic protection during the day should have a spare menstrual panty and is forced to undress to make this change. In addition, if this change takes place outside the home, it is necessary to store the used menstrual panties. Such periodic protection is therefore impractical to change, which encourages people to wear the same menstrual panties for many hours.Apart from the fact that the user may experience discomfort when wearing such periodic protection for a long time, this type of use can lead to leaks when the menstrual panties are no longer able to absorb the flow.

[0008] The object of the present invention is to propose a new textile menstrual protection underwear in order to respond at least to a large extent to the preceding problems and to further lead to other advantages.

[0009] Another aim of the invention is to provide a menstrual protective textile undergarment which is reliable in its operation.

[0011] Another aim of the invention is to propose a textile menstrual protection underwear which is inexpensive, so as to limit the cost of such underwear compared to the known and aforementioned menstrual panties.

[0012] Another aim of the invention is to propose a simple menstrual protective textile underwear, both from the point of view of its implementation and from the point of view of its manufacture.

[0013] Another aim of the invention is to propose a menstrual protective textile underwear which is universal and configured to adapt to different morphologies of users.

[0014] Another aim of the invention is to propose a textile menstrual protection underwear which is reusable.

[0015] Another aim of the invention is to propose a menstrual protective textile undergarment which is satisfactory in terms of comfort of use.

[0016] Another aim of the invention is to limit the quantity of textile material used to form menstrual protection, compared to existing solutions.

[0017] According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with a menstrual protective textile undergarment comprising: (i) a main body intended to be in contact with a lower region of the pelvis of a user, the main body comprising a waist opening, a ventral portion delimited by a front upper edge and a front lower edge, a dorsal portion delimited by a rear upper edge and a rear lower edge, and two lateral edges opposite the waist opening, the ventral portion and the dorsal portion being fixed integrally to each other, the front upper edge and the rear upper edge delimiting the waist opening; (ii) a bottom comprising at least one absorbent piece, the bottom and each of the two lateral edges of the main body being configured to delimit one of the two leg openings.In the textile underwear according to the invention, the underwear comprises a detachable fastening means configured to securely and detachably fasten the bottom to the front lower edge and to the rear lower edge of the main body.

[0018] The underwear according to the first aspect of the invention is a textile underwear. In this sense, the underwear according to the invention is formed from a textile material. Such an underwear is intended to be worn by a user a repeated number of times. Such an underwear is intended to be washed a repeated number of times. By textile, it is meant that the underwear according to the invention is formed from a woven fiber material and / or a non-woven fiber material. A woven fiber material is for example obtained by weaving or knitting. Said textile material is for example formed from synthetic fibers and / or natural fibers.

[0019] The underwear according to the first aspect of the invention is intended to provide menstrual protection to its user. The underwear according to the invention is intended to absorb menstrual flow. In the underwear according to the invention, the at least one absorbent part of the bottom is intended to absorb said menstrual flow. It is understood that the user is advantageously a menstruating user. The absorbent part is configured to be able to absorb a determined volume of menstrual flow. It is noted, without limitation, that the underwear according to the first aspect of the invention can absorb any other bodily fluid of the user. In particular, the underwear according to the first aspect of the invention can absorb, in addition to menstrual flow, sweat excretion and / or urinary losses.

[0020] In the underwear according to the first aspect of the invention, the main body intended to be in contact with a lower region of the pelvis of a user. It is understood that the main body is intended to surround the lower region of the user's pelvis at the waist opening. The ventral portion of the main body is intended to cover a ventral region of the user when the two leg openings are defined in the undergarment according to the first aspect of the invention. The dorsal portion of the main body is intended to cover a dorsal region of the user when the two leg openings are formed in the undergarment according to the first aspect of the invention. It is understood that, when the two leg openings are unformed, the main body can be moved in rotation around the lower region of the user's pelvis. In particular, the dorsal portion can be positioned on the dorsal or ventral region of the user while the ventral portion is respectively positioned on the ventral or dorsal region of the user.

[0021] The underwear according to the first aspect of the invention may be of the type of panties, a thong, boxers, a bodysuit or any other underwear. When the underwear according to the first aspect of the invention is of the type of panties, a thong or boxers, the upper front edge and the upper rear edge comprise an elastic band.
