Abstract
Description
Technical Field
[0001] This utility model relates to the field of hygiene products technology, specifically a wearable menstrual pant. Background Technology
[0002] In the field of feminine hygiene products, traditional sanitary napkins have always been the mainstream choice. Traditional sanitary napkins are typically worn by sticking them onto underwear and mainly consist of a top layer, an absorbent core, and a bottom layer. However, this traditional design still has the following technical problems:
[0003] 1. Traditional sanitary napkins have a short usage time and need to be changed frequently. When menstrual flow is heavy, they often need to be changed every 2-4 hours. This is extremely inconvenient for women who are working, studying or engaged in other activities. It not only increases the cost of use, but may also lead to embarrassing situations due to not changing them in time.
[0004] 2. Traditional sanitary napkins adhere completely to the skin of the private area when used, making it difficult to keep the area dry. Furthermore, after menstrual blood is absorbed by the core, some of the blood can seep back to the surface layer and stick to the skin of the private area again, causing discomfort to the user. In addition, prolonged exposure to a damp environment can easily breed bacteria, increasing the risk of gynecological diseases in women.
[0005] To address the aforementioned issues, the inventors have innovatively designed women's menstrual care products, developing a wearable menstrual panty that can be used for a long time without frequent changes and keeps women dry. This not only improves women's quality of life during menstruation but also provides them with a more convenient and healthy care experience in various scenarios. Utility Model Content
[0006] This invention provides a wearable menstrual panty that solves the technical problems of traditional sanitary napkins, which are completely attached to the skin of the private parts, causing stuffiness and dampness, and menstrual blood sticking to the skin.
[0007] This application provides the following technical solution:
[0008] A wearable menstrual panty includes disposable underwear and a receiving container located in the crotch area of the underwear to collect menstrual blood. The bottom of the receiving container has an absorbent core, and the upper edge of the receiving container contacts the user's vulva. After wearing the panty, the vulva does not contact the absorbent core at the bottom of the receiving container.
[0009] Beneficial effects:
[0010] 1. By improving disposable underwear, a receiving container for collecting menstrual blood is set in the crotch area of the underwear, and the vulva does not come into contact with the absorbent core at the bottom of the receiving container after wearing, forming a suspended space between the vulva and the absorbent core; compared with traditional sanitary napkins or sleeping pants, which are completely attached to the skin after wearing and are prone to causing stuffiness, dampness and sticky menstrual blood, the structural design of this application allows the menstrual blood to fall into the bottom of the container and be absorbed by the absorbent core, so that the menstrual blood will not stick to the skin of the private parts again, making it more comfortable and dry to use.
[0011] 2. Because the vulvar skin does not directly contact the absorbent core at the bottom that has absorbed menstrual blood during use, it is more comfortable and drier to use. In addition, the receiving container has a certain amount of absorbent space, so it does not need to be changed as frequently as sanitary napkins, and can be used for a longer time, reducing the inconvenience caused by frequent changes.
[0012] Furthermore, the receiving container has a crescent-shaped concave cavity structure.
[0013] Beneficial effects: It can better fit the female private parts, improve the comfort of use, and better absorb menstrual blood, reducing side leakage.
[0014] Furthermore, the depth of the concave cavity structure is 5-10 mm.
[0015] Beneficial effects: This depth range can adapt to the human physiological structure just right. The depth of 5-10mm is neither too shallow, which would result in the inability to effectively receive menstrual blood, nor too deep, which would cause the user to feel a foreign object or have difficulty moving.
[0016] At this depth, the menstrual blood can fall smoothly into the bottom of the concave cavity and be efficiently absorbed by the absorbent core.
[0017] Furthermore, the thickness of the absorbent core is 1-2 mm.
[0018] Beneficial effects: A thickness of 1-2mm ensures that the absorbent core has sufficient absorption capacity and absorption speed without taking up too much space; and at this thickness, the absorbent core helps maintain the shape of the cavity. An excessively thick absorbent core may expand and deform after absorbing menstrual blood, damaging the original structure of the cavity, affecting the leak-proof effect, and causing problems with the absorbent core coming into contact with the skin.
[0019] Furthermore, the absorbent core is bonded to the bottom of the receiving container.
[0020] Beneficial effects: The adhesive design of the absorbent core is beneficial to production and processing, and the absorbent core can be replaced according to the amount of menstrual blood, which makes it more flexible.
[0021] Furthermore, the absorbent core includes a bottom membrane, an intermediate absorbent layer, and a surface nonwoven fabric layer.
[0022] Beneficial effects: The absorbent core adopts the existing three-layer structure of sanitary napkins, which can both ensure absorbency and save production costs.
[0023] Furthermore, the container is heat-sealed or sewn together with the disposable underwear. This connection method simplifies the production process.
[0024] Furthermore, the receiving container is made of any one of liquid silicone, medical-grade silicone, medical-grade latex, or medical-grade rubber.
[0025] Beneficial effects: Using silicone or latex to make the container can improve the comfort of use. Silicone or latex also has a certain degree of resilience, which helps to maintain the concave cavity structure and avoid problems such as leakage of menstrual blood due to deformation. Attached Figure Description
[0026] Figure 1 This is a plan view of a wearable menstrual pant according to the present invention;
[0027] Figure 2 for Figure 1 A schematic diagram of the structure of the intermediate receiving container. Detailed Implementation
[0028] The following detailed description illustrates the specific implementation method:
[0029] The markings in the accompanying drawings of the instruction manual include: disposable underwear 1, receiving container 2, and absorbent core 3.
[0030] Example 1
[0031] like Figure 1-2 As shown, a wearable menstrual panty includes disposable underwear 1 and a receiving container 2 located in the crotch area of the underwear to collect menstrual blood. An absorbent core 3 is detachably mounted on the bottom of the receiving container 2. The upper edge of the receiving container 2 contacts the user's vulva, but the vulva does not contact the absorbent core 3 at the bottom of the receiving container 2 after wearing. Specifically, in this embodiment, the disposable underwear 1 is made of pure cotton, and the crotch area serves as the receiving container 2. The receiving container 2 and the disposable underwear 1 are connected as a whole by heat sealing or sewing, facilitating wearing and securing the receiving container 2. More preferably, the receiving container 2 is made of any one of liquid silicone, medical-grade silicone, medical-grade latex, or medical-grade rubber, which improves comfort and provides the silicone or latex with a certain degree of resilience, helping to maintain the shape of the receiving container 2 and preventing deformation that could lead to menstrual blood leakage.
[0032] like Figure 2As shown, the receiving container 2 has a crescent-shaped concave structure. This shape allows it to better fit the woman's private parts, improving comfort and better absorbing menstrual blood while reducing leakage. Specifically, the depth of the concave structure is 5-10mm, and the thickness of the absorbent core 3 is 1-2mm. This embodiment uses a concave depth of 10mm and an absorbent core 3 thickness of 2mm as an example. After the user wears it, there is a space between the vulva and the absorbent core 3. The menstrual blood falls onto the absorbent core 3, preventing the skin of the vulva from contacting the absorbent core 3. This avoids menstrual blood on the surface of the absorbent core 3 sticking to the skin again, causing discomfort to the user. Furthermore, because the absorbent core 3 does not adhere to the skin, it reduces the feeling of stuffiness and dampness during use, making it more comfortable to use. It also eliminates the need for frequent changes, allowing for longer wear time and reducing the embarrassment caused by inconvenient replacement.
[0033] The absorbent core 3 is adhered to the bottom of the receiving container 2. The absorbent core 3 includes a bottom film, an intermediate absorbent layer, and a surface non-woven fabric layer. Specifically, the three-layer structure of the absorbent core 3 adopts the existing structure and materials of sanitary napkins. For example, the bottom film is made of PE film, which is easy to adhere to the receiving container 2 and can also prevent absorbed menstrual blood from seeping through the bottom film and sticking to the receiving container 2, causing pollution to the outer pants. The intermediate absorbent layer is made of fluff pulp with added polymer materials, which has strong adsorption properties. This embodiment does not improve the material of the absorbent core 3, and will not be described in detail here.
[0034] Because the vulvar skin of this menstrual panty does not directly contact the absorbent core 3 at the bottom that has absorbed menstrual blood during use, it is more comfortable and drier to use, and does not need to be changed as frequently as sanitary napkins, allowing it to be used for a longer period of time. Moreover, it is thinner and drier than existing sanitary napkins and overnight panties, solving the problem of stuffiness and dampness caused by the private skin being completely in contact with the inner layer of the overnight panty, and menstrual blood sticking to the skin.
[0035] The above are merely embodiments of this utility model, and the utility model is not limited to the field covered by this embodiment. Commonly known structures and characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
