Problems solved by technology

Applicants have found, however, that conventional hydrophilic topsheets, especially absorbent hydrophilic topsheets, are not an ideal suitable element for absorbent products intended for internal use, especially interlabial use.
In fact such elements may be noticeably uncomfortable and cause pain and irritation to the user during use

example 1

[0157] The product size is 91 mm x 46 mm, and the thickness is 5.0 mm.

[0158] The following materials are included in the product:

[0159] • A starch size bonded rayon topsheet basis basis of about 15 g / m2, similar to that used to wrap over sanitary tampons (especially TAMPAX tampons), sold by BBA Nonwoven, Green Bay, Wisconsin.

[0160] • The core material is a carded batt blended with 50% rayon and 50% blended cotton. 50% rayon is Sarille L rayon fiber, 50% cotton blend is a blend of cotton fiber and 0.03% lyomin finish, sold by Brannoc, North Devon, England.

[0161] ●The backsheet is a polybutylene succinate adipate film, colored with Ampacet 110361 sold by Showa High Polymer Co., Tokyo, Japan, and the product brand is BIONELLE 3001. The backsheet is joined to the topsheet by seams to form a peripheral seal.

[0162] The core is attached to the backsheet with two helical hot-melt adhesives, and the hot-melt adhesive is centered on both sides of the overall keel devic...

example 2

[0165] The product size is 91 mm x 46 mm, and the thickness is 6.0 mm.

[0166] The following materials are included in the product:

[0167] • Thermally bonded nonwoven fabric with a basis weight of 17 g / m2, manufactured by Vliesstoffwerke Christian Heinrich Sandler GmbH & Co. KG (Schwarzenbach / Saale, Germany) under the tradename Sawabond 4313. The topsheet is mechanically modified to improve its comfort as described in US Patent Application Serial No. 09 / 637,440 filed on August 11, 2000.

[0168] • The absorbent core structure comprises a nonwoven acquisition layer (Texel Inc., Quebec / Canada) having a basis weight of 60 grams per square meter. The acquisition layer consisted of 50% PET (Celenese #295, sold by Celenese AG (Summit, NJ / USA)) and 50% Rayon / CMC Alloy fibers (Accordis, Mobile, Alabama / USA, trial code 2014), non-woven acquisition layer Crosslinked by needle punching process with an airlaid absorbent core having a basis weight of 300 g / m2. The absorbent core cons...

example 3

[0173] The product size is 91 mm x 46 mm, and the thickness is 6.0 mm. And include the same material and keel arrangement as Example 2. The softness and ability to conform to the labial vestibular structure of the overall product is enhanced by the use of a core slot structure instead of the core used in Example 2. It remains the same except for the following:

[0174] The softness of the entire product is due to the use of parallel (5 mm intervals) slots transverse to the machine direction (perpendicular to the length of the product) (each slot is 10 mm long and the next slot is 5 mm apart) Sexuality and the ability to conform to the labial-vestibular structures are enhanced. The slot extends from the top of the core to the bottom of the core and runs the full depth of the material. This alternative slot configuration allows for significantly less force required to bend the product when subjected to the V-bend test and the L-bend test, thereby facilitating insertion / applic...

Abstract

The present invention relates to an improved body contacting surface or topsheet for an absorbent device which is in contact with the aqueous tissue of the user's body. The aqueous body tissue may include, but is not limited to, aqueous tissue such as interlabial skin or tissue and mucosal tissue such as vaginal tissue. In one non-limiting embodiment, the topsheet comprises a moderately hydrophilic to substantially hydrophobic nonwoven web that is not absorbent. The topsheet is disposed on absorbent devices such as sanitary napkins, tampons, panty liners, interlabial devices, incontinence devices, bandages, and other articles. The present invention also relates to a method of retaining exudates from a source of exudates in a user. wherein at least a portion of the exudate source is located within an aqueous film having an irregular surface, such as the interlabial or intravaginal region of a female user. The present invention also relates to an absorbent article insertable into the interlabial region of a female user, the absorbent article comprising an absorbent storage core and a body-contacting vaginal discharge-receiving layer disposed over a on the storage core. Needle-punched communication is provided between the absorbent storage core and the body-contacting exudates-receiving layer. Additionally, the absorbent storage core includes a unitary web of fibrous material and may optionally include an absorbent gelling material and a plurality of perforations. The absorbent article also includes an insertion device, which may be an absorbent article inserter or a foldable reinforcing tongue integral with the absorbent article, the reinforcing tongue having fold lines.

Description

technical field [0001] The present invention relates to an improved body contacting surface or topsheet for use in absorbent articles, bandages, or other similar devices. More particularly, the present invention relates to a topsheet which is comfortable in contact with the aqueous tissues of the body. The invention also relates to absorbent devices such as sanitary napkins, tampons, panty liners, interlabial devices, incontinence devices, bandages and the like comprising such topsheets. The present invention also discloses an improved absorbent structure for absorbent articles. The present invention also relates to a method of trapping discharge from a source of discharge in a user, wherein the source of discharge is at least partially located within an aqueous membrane having an irregular surface (such as the interlabial area or vaginal area). Background technique [0002] A wide variety of absorbent articles designed to absorb body exudates such as menses, urine, feces...
