[0043] The present invention is described further by way of example with reference to the accompanying drawings, of which:

DESCRIPTION OF EMBODIMENTS
[0049] The incontinence product shown in the Figures is suitable for babies, children and adults and comprises:
[0050] (a) a disposable pad 3 shown in
[0051] (b) an outer reusable pull-on pant 5.
[0052] The outer pull-on pant 5 is a standard pant construction made from any suitable material and includes a waist 9, which is typically elasticised, and a body section 11 that defines leg openings 13. More particularly, the body section 11 includes a front section 21, a rear section 23, and a sling section 25 that extends between the front and rear sections and, in use, extends between the legs of the person. The edges of the sling section 25 are elasticised and formed to snuggly fit around the legs of the person and cup around and support the pad 3 thereby minimise any leakage from the pad. The pant 5 is typically formed from a stretchable material to help to closely fit the pant onto the body of the person and contribute to retaining the pad 3 in position by virtue of the stretchiness of the material.
[0053] The pant 5 also includes a plurality of hook fastener sections 15 on an inside surface of the front section 21 and the rear section 23 of the body section 11 of the pant 5. Each hook fastener section 15 has a plurality of hook fasteners 19 extending from one surface of a backing section 29 of the section 15. Typically, each hook fastener section 15 is a single plastic moulding which is an all in one structure comprising the backing section 29 and the plurality of fasteners 19 extending from the backing section. The hook fastener sections 15 may be any other suitable construction. The hook fastener sections 15 are secured, for example by being stitched, to the inside surface of the body section 11 of the pant 5 at selected locations at a front and a back of the pant, i.e. at selected locations on the front section 21 and the rear section 23 of the pant. One such section 15 with hook fasteners 19 is shown in
[0054] The disposable pad 3 is shaped to fit around the crotch region of the person wearing the product so as to conform closely to the crotch region to maximise capture of waste and to make it less apparent than would otherwise be the case that the person is wearing the incontinence product. Minimising the visual impact of the product can be a particularly sensitive issue for children and adults.
[0055] The pad 3 includes elasticised sides to help to shape the pad 3 to conform to the shape of the crotch region to snuggly hold the pad 3 against the person. The elasticised sides are also formed to define guards that minimise leakage when the pad 3 is held in an operative position.
[0056] The pad 3 is a multi-layer laminate construction that is formed from sheets of material.
[0057] The pad 3 comprises an outer cover stock 7 (see
[0058] The disposable pad 3 further comprises a waterproof film (not shown) for containment of solids and liquids. The film is made from a breathable biodegradable starch-based material.
[0059] The disposable pad 3 further comprises a non-chlorine bleached fluff pulp (as described above) layer (not shown) made from farmed trees (or unbleached fluff pulp from farmed trees or bamboo) that has been combined with a super absorbent polymer SAP for absorbency. Regular petrochemical based SAP can be replaced with a SAP derived from sustainable resources once a suitable product has been developed. SAP can be beneficial to agriculture where it acts as a water storing granule, or if composted it has been shown to biodegrade by the combined actions of white rot fungi and bacteria.
[0060] The disposable pad 3 further comprises an optional removable flushable liner (not shown) that can be used to aid in disposing of faecal matter hygienically.
[0061] Alternatively, the whole pad 3 can be disposed of hygienically via a macerator/grinder unit which flushes it into the sewer where it goes for treatment and becomes part of the biomass which in turn is beneficially used for application in agriculture, or composted and then used for beneficial use in agriculture as a soil conditioner. The macerating units are readily available and used for disposal of regular non-biodegradable plastic disposable pads, however these types of pads are adding large quantities of non-biodegradable plastic particles to our environment which is a problem for agriculture use because of its cumulative effect and potential harm to organisms.
[0062] The disposable pad 3 further comprises an inner lining (not shown) which in use contacts the person wearing the disposable pad 3. The inner lining is made from a non-woven material, such as biodegradable viscose, cotton or PLA. This material is an alternative to the traditional polyethylene non-woven material used in current disposable pads.
[0063] Polyethylene is regularly used for the inner lining of disposable pads (and nappies) because of its softness and non-absorbing properties, thus providing a stay-dry surface that does not wick liquid from inside the disposable pad 3 to the outside. It also is generally non-irritating when in contact with the skin.
[0064] A compostable non-woven material is preferred by the applicant on environmental grounds, although it is emphasised that the present invention also extends to the use of non-compostable materials for the inner lining.
[0065] Compostable non-woven materials with similar stay dry and soft properties to polyethylene are made using alternative materials.
[0066]
[0067] With reference to
[0068] It can readily be appreciated that with this combination of pad 3 and pant 5, the pant 5 retains the pad 3 in position, by virtue of engagement of the hook fasteners 19 with the pad 3 and the close-fitting construction of the pant 5.
[0069] The above-described disposable incontinence product of the invention has a number of significant advantages.
[0070] The fitting sequence is simple and straightforward. It is possible to replace existing pads quickly and easily, with minimal disturbance to clothing. In particular, it is not necessary for the person to remove trousers or stockings to replace a pad 3.
[0071] In addition, the overall product design and construction is simple and effective. The pull-on pant 5 is suited particularly well to retaining the disposable pad 5 in position on the person. The use of the hook fasteners 19 on the pull-on pant body 11 rather than on the disposable pad 3 makes the construction of the pad 3 straightforward. This is a significant difference between the product of the invention and disposable incontinence products known to the applicant.
[0072] In addition, the positioning of the hook fasteners 19 at the front and back of the body of the pant 5 (and not in the crotch area) also provides additional upward support for the pad 3 by gripping and holding up both the front and back ends of the pad 3 to prevent it sagging down into the crotch area once full of urine. This is an important feature as a fastening means in the crotch area e.g. the regular adhesive strips used to adhere pads to garments, only provides a means to prevent slippage and offers little support to maintaining the pad up close to the body, but relies entirely on the gusset of the outer garment to provide upward support. This may be adequate for sanitary towels which are not required to contain in excess of 1 kg or more, but is inadequate e.g. where adhesive strips (or any fastening means) in the crotch area are used for locating incontinence pads in a pant. Pads sagging away from the body are a major cause of embarrassing leakage from pads and the gussets of stretch pants are not able to provide sufficient support to prevent this.
[0073] In addition, the overall external appearance of the fitted product is such that it would not be immediately apparent, if apparent at all, that the person is wearing the product. This would be particularly the case where the disposable pad is a thin pad made from a highly absorbent material. This is a particularly important issue for children and adults who are often self-conscious of appearance.
[0074] Many modifications may be made to the embodiment of the product of the present invention described above with reference to the accompanying drawings without departing from the spirit and scope of the invention.
[0075] For example, whilst the embodiments of the nappy bodies are described in the context of being manufactured from compostable materials, the present invention is not so limited and extends to disposable materials generally.
