Definitions

  • This invention relates to absorbent, washable and re-usable garments namely brassieres (herein called "bras"), worn by women around the breasts.
  • the invention extends to bras structurally adapted for use by women, especially post-partum and lactating women, undertaking occupation- related or exercise-related activities, and at the same time nursing an infant.
  • “Absorbent barrier” identifies a built-in flat or curved, layered assembly of selected textiles capable of receiving liquids from a specific side, then containing and thereby preventing the onward travel of liquids while allowing gases including water vapour to pass through the assembly.
  • the cups of a bra comprising the absorbent barrier, is not separable from the remainder of the bra. There is no removable, disposable absorbent pad.
  • Backsheet is a commonly used term at least in the patent literature for the innermost or skin- contacting layer of an absorbent garment and "Topsheet” is a commonly used term for an outward and at least partially waterproofed layer of an absorbent garment.
  • the waterproofed layer is both gas-permeable and waterproof, and in most options that layer lies beneath a decorative layer.
  • “Bamboo textile” refers to a textile comprised of reconstituted cellulose derived from bamboo in a process like that for making Rayon®. The Applicants prefer to not use bamboo in sports gear. "Bra” is a commonly used abbreviation of "brassiere”.
  • “Launderable” or “washable” refers to a property of withstanding repeated laundering cycles between use, washing and re-use such that the washed clothing or undergarment is restored by removal of contained liquids from within.
  • launderable applies to wash cycles at over 70 degrees Celsius.
  • Disposing Bra is a kind of bra that allows breast feeding; preferably in a discreet way. an absorbent barrier capability for absorbing and retaining liquids including milk and sweat discharged from the breasts. Often the liquid is breast milk associated with or following a pregnancy.
  • the preferred layer is known as "a functional 100% polyester fabric” or textile. It is easily wetted and is highly water-permeable. It is often referred to as “quick-dry”, “dri-cool” or “dry-cool” and is supplied by a large number of manufacturers. It may include elastane (Spandex®) for stretchability.
  • Sports bra is a standard term for bras that allow women to exercise freely while potential independent motion by their breasts during activities is controlled.
  • Texttile refers to a woven or knitted textile or fabric. Any non-woven component to be included in this document will be specifically identified.
  • Top refers to a bra with side panels extended toward the waist or hip. Physically active mothers may want three functions (sports bra, nursing bra, and sports top) in the one upper garment.
  • Waterproof yet vapour-permeable is a property of a layer in which liquid water is blocked from capillary flow through the layer, yet water vapour, like any other gas, can pass through the layer.
  • Flow or just leakage may occur involuntarily and perhaps from a secondary duct. Even 1 ml of leakage has a propensity to mark one's clothing with a dark spot or a stain at or close to the nipple. People are very conscious of such an effect especially at this location.
  • bra pads that have a capacity to absorb inadvertently released milk or other liquids discharged from a person' s body without allowing leakage of liquid, so that the mother's clothing has a normal or unremarkable appearance. It desirable to not use bra pads.
  • the patent literature review below excludes bras that include polyurethane film or the like as a 90 waterproofing layer.
  • waterproofing is an included property of a garment in the general prior art such as the incontinence garment fields, it has been provided by one or more layers each comprised of a film of a polyurethane
  • the films are claimed to provide gas permeability along with waterproofing. They may have a number of dispersed pores throughout or perhaps permeability arises by virtue of being thin.
  • the Applicant's experience is that polyurethane films are not 95 particularly water vapour-permeable. They do not survive hot laundering for many times, when they become water-permeable. It is difficult to shape a flat polyurethane film to the contours of the breast.
  • polyurethane films able to be stitched, especially in a contoured manner as required in a launderable, absorbent, leakproof bra.
  • polyurethane films sufficiently elastic to accomodate the change in shape that may occur during a single day. Stitching will tend to provide 100 a path for capillary flow of liquid.
  • bras that do not cater for moisture management.
  • the literature can be grouped as follows: Some (group A) are intended to be absorbent and to be disposed of after a single use. Many (group B) include removable absorbent pads which 105 may be disposed of or washed separately. Few (group C) provide a completely launderable option.
  • Bras that are constructed in order to provide a "sports bra” functionality in addition to an absorbent property are a subset; and group E provides a completely launderable and re-usable option.
  • Maternity bras do not have much capacity to absorb inadvertently released milk or other liquids 120 discharged from a person' s body, preventing leakage, so that the person' s clothing retains a normal appearance. Another problem is that absorbent bras (or pads within) are not launderable and reusable. Another problem is the provision of maternity bras capable of providing breast support during activity whether during ordinary occupations or during exercise in a gymnasium or outside, even though the properties of the breasts change from hour to hour, and from week to week.
  • Post-natal depression is a significant problem. It is hoped that easier access to an exercise facility after birth will reduce post-natal depression; since exercise makes participants feel well. Therefore an effective exercise bra not subject to leakage problems would be useful.
  • a basic problem to be solved relates to providing nursing women with better clothing; especially absorbent and waterproofed undergarments, so that they can more readily restore muscle tone by 130 means of walk, jogging, or exercise programmes without embarrassing leakage.

  • a front view (Fig 13) and a back view (Fig 14) show a complete "sports range absorbent top" having a built-in bra.
  • the non-openable cups 100 include the "absorbent barrier" multi-layer construction designed for retaining leakage from the breasts.
  • a mother would wear this garment when undertaking activities either away from or accompanied by her baby, or 495 when weaning the baby. Activities could include housework, walking, jogging, and exercising at a gymnasium. Since this garment is a top, it can be styled with appealing or fashionable patterns, colours, and textures.
  • bras and panties 500 properties as are suitable for use by incontinent persons. Childbirth often initiates temporary bladder leakage.
  • the Applicants shall produce matching styles for both bras and panties, where either the bra, or the panties, or both include the absorbent barrier structure to a suitable capacity.
  • Applicant's designs do not cater for removal of the absorbent material as a separate item from inside a pouch, for example.
  • the waterproof layer is covered by a decorative layer 104 such as of lace, closely resembling the external appearance of a conventional bra.
  • the absorbent bras could be used for absorbing sweat as opposed to the main focus above, of absorbing milk.
  • Wire supports are an option in bra design which can be applied in any of the Styles described and 510 shown herein.
  • a polyester or polyamide with elastane innermost layer 101 may be combined with a thick polyamide backing 102 for absorbtion, and the waterproofing layer 103 may include 515 decorative aspects. It may be possible to spray a waterproofing layer on to an outer surface of the absorbent layer. That would reduce the number of layers.
  • the invention provides a range of comfortable and shape-conforming (since they include elastic material) maternity bras having sufficient capacity for absorbing fluids.
  • the bra safely traps
  • the absorbent barrier provided by the invention will improve the confidence of nursing mothers when in public.
  • the waterproofing capability is included in a flexible, vapour-permeable woven textile preventing seal breakdown. Vapour permeability and wicking together ensure the skin is not damp
  • waterproofing is applied to the fibres of a textile selected to become the waterproofed layer and does not comprise a separate layer sealed to the textile, before or after it is shaped into a bra cup.
  • Some designs of the maternity bra are optimised for use by active persons, such as by a 535 mother who uses exercise to restore her body and muscle tone after giving birth, while she is still nursing her baby at home, or out walking, or in between exercises.
  • Absorbent yet non-nursing options are for use by a mother who is weaning her baby.
  • Garments look like regular bras or maternity bras, even if seen as contours visible through overlying garments. Bulk is reduced in part by use of advanced textiles.
  • the shutter design provides more comfortable and more easily accessible support means for the nursing mother's breasts; the size of which may vary through the day as well as over time.
  • Absence of rustling noises and matching styles of bras and panties means that the wearer use the garments without embarrassment.
  • This clothing can be simply dropped into a washing machine, washed, spun, and dried. 545 Drying can be assessed by weight or by feel.

Abstract

Selon l'invention, les deux bonnets d'un soutien-gorge ou d'une brassière non-rigide comprennent 4 couches : un matériau mèche élastique, un matériau absorbant, une couche étanche à l'eau de textile imprégné d'un fluoropolymère résistant au blanchiment, à faible angle de contact, et un extérieur décoratif. Le textile traité a une perméabilité aux gaz à peine modifiée, comprenant de la vapeur d'eau, et bloque la totalité de l'écoulement de liquide aqueux. Des variations comprennent des types d'allaitement ou de non-allaitement d'un soutien-gorge absorbant, d'un soutien-gorge d'exercice et d'un dessus de sport. Des soutien-gorges d'allaitement ont une ouverture de "cadre d'obturation" ayant des bords élastiques, de telle sorte que le sein peut être exposé à une étendue variable lors de l'allaitement. Les bords élastiques peuvent glisser l'un sur l'autre, en n'étant pas directement attachés.
