Patent Application
20150141945
The present invention relates to the field of feminine hygiene. More particularly, the invention relates to a disposable feminine hygiene utility.
“Feminine hygiene” is an umbrella term used to describe toilet products for menstrual fluids collection.
Regular menstruation (also called eumenorrhea) lasts for a few days, usually three to five days, but anywhere from two to eight days is considered normal. The average menstrual cycle is 28 days long from the first day of one menstrual period to the first day of the next. A normal menstrual cycle is typically 21 to 35 days between menstrual periods.
The average volume of menstrual fluid during a monthly menstrual period is 35 milliliters (or four to six tablespoons of menstrual fluid) with 10-80 milliliters considered typical. Menstrual fluid contains blood, cervical mucus, vaginal secretions, and endometrial tissue. The color of menstrual fluid is reddish-brown, a slightly darker color than blood.
Most females use something to absorb or catch their menses. There are a number of different disposable menstrual absorption products available for use today. Sanitary napkins and tampons are the most common disposable absorption products in use.
Sanitary napkins, or pads, are somewhat rectangular- shaped pieces of material worn in the underwear to absorb menstrual flow, often with “wings”—pieces that fold around the undergarment, or an adhesive backing to hold the pad in place. Disposable sanitary napkins may contain wood pulp or gel products, usually bleached and with a plastic lining. Most sanitary napkins are held in place by adhesive or wings.
A menstrual pad or a sanitary napkin is worn during a woman's period to absorb her menstrual flow. It is worn externally, between the vulva and a woman's undergarment. Menstrual pads are made from a range of different materials.
Tampons, such as disclosed by U.S. Pat. No. 6,890,325 and U.S. Pat. No. 6,316,688, are disposable cylinders of treated rayon or cotton blends or all-cotton fleece, usually bleached, that are inserted into the vagina, to absorb menstrual flow. A regular tampon is usually built out of a mass of cotton, rayon, or a mixture of the two.
Tampons come in various sizes, which are related to their absorbency ratings and packaging. The outward appearance of a tampon is similar in all brands, but their absorbency varies. The two main differences are in the way the tampon expands when in use: some types of tampons will expand axially (increase in length), while others will expand radially (increase in diameter). All tampons have a thread for removal and some have an additional outer cover to aid insertion and withdrawal. Tampons are sold individually wrapped to keep them sanitary. Tampons can range in size from 1½ to 4½ inches.
Tampons have various associated health risks. Tampons were found to be a cause of toxic shock syndrome (TSS) cases. The blame is in their high absorbency, as well as in their overnight use, for increased incidences of toxic shock syndrome. Materials used in most modern tampons are so highly absorbent that they pose the risk of absorbing the natural discharge and upsetting the natural moisture balance, which is what enables toxic shock syndrome to occur.
Some women experience a heavier-than-average menstrual flow. Typical to this group is a more observable shedding of the uterus's endometrium lining during menstruation. The shed endometrium lining appears here as small pieces of tissue mixed with the blood. These pieces of tissue are in fact common, but occur more frequently in women who experience a heavier-than-average menstrual flow.
The health risks of the use of tampons and the disadvantages of sanitary napkins with women who experienced leakage, entails the need of a better solution to the problem of absorbing menstrual fluids.
All the methods described above have not yet provided satisfactory solutions to the problems of disposable feminine hygiene utilities.
It is an object of the present invention to provide a solution to the above-mentioned and other problems of the prior art.
Other objects and advantages of the invention will become apparent as the description proceeds.
In one aspect, the present invention is directed to a disposable feminine hygiene utility (10), comprising:
The adjusting may be carried out without contact between the absorbent pillow (20) and a user's body, resulting in preventing irritation of the user's body.
Preferably, the sleeve (14) is structured in the sanitary napkin (12).
The sleeve (14) may be attached to the sanitary napkin (12) by sewing, welding, adhering, and so on.
Preferably, the absorbent pillow (20) is flattened at the bottom thereof
According to one embodiment of the invention, the absorbent pillow (20) is made of spongy material, thereby allowing the pillow to deform according to a user's body that touches the absorbent pillow (20).
The utility may be further disposed in a pack (16), thereby keeping the utility sterilized until use.
Preferably, the pack (16) is designed to allow placing therein a used utility, and keeping thereof sealed.
In order to prevent smooth adjusting of the location of the absorbent pillow, the side of the pillow that turns to the undergarment may comprise a waxed layer. This provides also an additional layer that isolates the undergarment from menstrual fluids and the like.
The reference numbers have been used to point out elements in the embodiments described and illustrated herein, in order to facilitate the understanding of the invention. They are meant to be merely illustrative, and not limiting. Also, the foregoing embodiments of the invention have been described and illustrated in conjunction with systems and methods thereof, which are meant to be merely illustrative, and not limiting.
Embodiments and features of the present invention are described herein in conjunction with the following drawings:
It should be understood that the drawings are not necessarily drawn to scale.
The present invention will be understood from the following detailed description of preferred embodiments, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail.
The acronym FHU refers herein to a Disposable Feminine Hygiene Utility.
The FHU 10 of
In order to use the FHU 10, the user places the FHU 10 between an undergarment of the user and hers body.
The position of the absorbent pillow with reference to a feminine anatomic section can be changed after placing FHU 10 between an undergarment of the user and the user's feminine anatomic section. Thus, if after a while the user feels uncomfortable with the location of the pillow, the location can be changed in a desired direction by pulling the corresponding wire 18.
In order to prevent smooth adjusting of the location of the absorbent pillow, the side of the pillow that turns to the undergarment may comprise a waxed layer. This provides also an additional layer that isolates the undergarment from menstrual fluids and the like.
FHU 10′ comprises two major parts: a sanitary napkin, which is marked herein by reference numeral 12, and an elongated absorbent pillow, marked herein by reference numeral 20 (which comprises two wires 18, as in the embodiment of
The absorbent pillow 20 is a separate entity from the sanitary napkin 12, as illustrated in
After the FHU 10′ is attached to the undergarment of a user, and the user wears the undergarment, wires 18 are useful for shifting the location of the absorbent pillow 20 with reference to the sanitary napkin 12, in order to place the absorbent pillow 20 in a desired location.
As the sanitary napkin 12 comprises an absorption pad, the absorbent pillow 20 increases the absorption ability of the FHU 10′. Furthermore, a user thereof may dispose of the absorbed pillow 20, and still use the sanitary napkin 12, which is less absorbed. Thus, instead of replacing the entire FHU 10′, the user may dispose of the absorbent pillow, which is faster than replacing the entire FHU 10′.
The arrows in
As illustrated, the bottom of the absorbent pillow 20 is substantially flat, in order to correspond to the flat form of the absorption pad 28 of the sanitary napkin. The flat bottom form of the absorbent pillow may be achieved by a design which provides the flatness. Alternatively, the absorbent pillow may be made of spongy material and the like, which allows deforming the absorbent pillow according to the pressures thereon.
The sanitary napkin 12 is attached to undergarment 26 by wings 22, which are binding undergarment 26 from both of its sides, thereby providing additional protection against leakage of menstrual fluid and help to secure sanitary napkin 12 in place. Adherence material 30 is used here to fix wings 22 of sanitary napkin 12 onto undergarment 26, while wings 22 are wrapped around the sides of undergarment 26 to add additional leak protection and help secure sanitary napkin 12 in place.
The FHU, which is referred to herein by reference numeral 10′, comprises a structured sleeve 14, to attain the centered position of absorbent pillow 20 with regard to the sanitary napkin 12.
As sleeve 14 separates between a user's body and the absorbent pillow 20, the operation of shifting the pillow is carried out without a contact between the pillow and the user's body, i.e., without irritating the user's body.
Feminine hygiene utility with a sleeve provides some different characteristics derived from its structural construction. The sleeve 14 is made from permeable material to allow leaking fluid to pass through.
According to one embodiment of the invention, the sleeve (14) is structured in the sanitary napkin (12).
The structure can be carried out by adhering the sleeve to the napkin, sewing the sleeve to the napkin, welding the sleeve to the napkin, and so on.
The arrow in
FHU 10″ is individually wrapped, and stored in a pack 16. The wires 18 are rolled such that they do not pass the borders of the sanitary napkin 12. The pack may be made of cellophane, nylon, and so on. The pack may also be made of cardboard or plastic, in a box form.
According to one embodiment of the invention, the pack (16) is designed for storing a plurality of FHUs.
According to one embodiment of the invention, the pack is designed to enable sealing thereof after opening. This way, a user may place a used utility in the pack thereof, thereby preventing contamination from the used FHU.
