Description

Absorbent article

Embodiments of the present invention relate to absorbent articles.

In general, the endometrium of women of childbearing age periodically proliferates by secreted hormones to prepare for the implantation of the embryo, but if it does not become pregnant, the endometrium falls off on its own, and this phenomenon is called menstruation, that is, menstruation. The menstrual cycle can be divided into follicular and luteal phases, and ovulation occurs during the transition from follicular phase to luteal phase. During the follicular phase, the secretion of female hormone (estrogen) from the ovary increases, and accordingly the menstruation stops and the endometrium of the uterus multiplies and begins to thicken. At the same time, if the ovaries mature in one ovary and the menstrual cycle is 28 days, ovulation occurs around 14 days after the start of menstruation. In the ovary after ovulation, luteinizing hormone (progesterone) secretion increases, which helps prepare for endometrial implantation. If you don't get pregnant, the endometrium will come off on the 28th day.

The normal menstrual cycle is usually between 21 and 35 days (average 28 days) at intervals between two consecutive menstrual start dates, lasting 3 to 8 days, and menstrual blood varies from person to person, but averages 35 ml, up to 10 to 80 ml See as.

During the menstrual period, a sanitary napkin is worn to prevent leakage of menstrual blood. Such sanitary napkins include an attached sanitary napkin such as a pad and an implantable sanitary napkin such as a tampon. Pads are attached to underwear to absorb menstrual blood, and tampons are inserted into the vagina to absorb menstrual blood.

The pad-shaped sanitary napkin is generally made of an absorbent layer between waterproof sheets arranged up and down, and a pore is formed on the upper sheet so that the menstrual blood is discharged downward and absorbed by the absorbent layer. The pad sanitary napkin must be replaced periodically due to the limited absorption of the absorbent layer, and the used sanitary napkin is discarded. Conventionally, there was only a disposal method such as wrapping the used sanitary napkin with a new sanitary napkin packaging material or wrapping it with tissue paper.

FIG. 3 is an exploded perspective view for explaining the absorbent article 10 of FIG. 1, and FIG. 4 is an exemplary view for explaining a disposal method using the first acting member 130 of the absorbent article 10 of FIG. 1.

Here, the absorbent article 10 means an article for absorbing impurities such as urine and menstrual blood and preventing leakage to the outside. In addition, as illustrated in FIG. 1, the upper surface of the absorbent article 10 means a surface contacting the user's skin, and the lower surface means a surface opposite to the upper surface with the absorbent layer interposed therebetween. In the present specification, the absorbent article 10 is capable of absorbing any kind of impurities, but hereinafter, for convenience of description, the case of the sanitary napkin absorbing menstrual blood will be mainly described.

1 to 4, the absorbent article 10 according to an embodiment of the present invention includes an upper sheet 110, an absorbent sheet 150, a lower sheet 120 and a first acting member 130 can do.

The upper sheet 110 is a sheet disposed on an upper surface contacting the user's skin, and transmits liquid impurity to the absorbent sheet 150. The upper sheet 110 may include a liquid-permeable non-woven sheet that protects a user's skin by quickly passing impurities and preventing backflow of impurities absorbed by the absorbent sheet 150. The upper sheet 110 may be a single layer, but as illustrated in FIG. 3, it may be formed of a multi-layered sheet such as a cover layer 111 directly contacting a user's surface.

The upper sheet 110 has a smooth surface texture, so even if it comes into direct contact with the user's skin, it causes less irritation to the user's skin, resulting in less trouble. The upper sheet 110, because the liquid-permeable non-woven fabric itself can easily absorb the liquid, absorbs the liquid immediately even if body fluids such as urine or sweat are discharged from the user, and does not stick well to the skin and does not cause discomfort to the user Does not. However, since the upper sheet 110 may have skin side effects due to skin friction due to long-term wearing, humid air, etc., the upper sheet 110 may be coated with a skin protection composition.

As one embodiment, the upper sheet 110 is a thermal bonding (thermal bonding non) non-woven fabric, spun-bond (spun-bond) non-woven fabric, spun-lace (spun-lace) non-woven fabric, through-air bonding (through-air bonding) non-woven fabric, etc. may be used Can. Further, the upper sheet 110 may be formed by mixing one or more fibers selected from cotton, rayon, polyester, polyethylene, polypropylene, and polyethylene terephthalide, for example.

The size and shape of the absorbent sheet 150 is not limited, and can be modified to meet absorbent capacity requirements and provide comfort to the wearer. The absorbent sheet 150 may include an absorbent core and a core wrap sheet.

The absorbent core absorbs impurities such as menstrual blood that has passed through the upper sheet 110 at a high speed, and functions to retain impurities to prevent the absorbed impurities from contacting the skin again. The absorbent core may include an absorbent core-forming material, and may include, for example, a liquid absorbent material such as a polymerized polymer using polyacrylic acid as a main raw material. The core wrap sheet supports the absorbent core and prevents impurities absorbed by the absorbent core from leaking out and prevents the absorbent core from being broken or clumped. The core wrap sheet may be laminated to the top and/or bottom of the absorbent core, or may be adhered to the absorbent core in a form surrounding the absorbent core. The core wrap sheet can be a tissue or non-woven fabric with a hydrophilic function.

For example, a thermally bonded non-woven fabric or a vent-bonded non-woven fabric may have a hydrophilic function by being manufactured using a fiber treated with a surfactant, and in the case of a spunbonded nonwoven fabric, raw materials such as polypropylene or polyethylene are spun at high temperature. By manufacturing the nonwoven fabric by treating the nonwoven fabric itself with a surfactant, it can have a hydrophilic function. The nonwoven fabric may be, for example, a spunbond nonwoven fabric, a thermally bonded nonwoven fabric, a melt blown nonwoven fabric, a spunbond-meltblown-spunbond nonwoven fabric, etc., and polyester, polyethylene, polypropylene, etc. may be used as the fiber of the nonwoven fabric. have.

The lower sheet 120 is coupled to the upper sheet 110 with the absorbent sheet 150 interposed therebetween, and may have liquid impermeability. The lower sheet 120 is a liquid-impermeable sheet that prevents contamination of the wearer's clothing or the surrounding environment by preventing impurities from leaking to the outside. The lower sheet 120 may include a breathable waterproof film, and may optionally further include a liquid impermeable nonwoven sheet. The lower sheet 120 may include a first adhesive film 121 to perform a function of attaching the absorbent article 10 to underwear or the like.
