SPECIFICATION Sanitary towels
5 Theinvention relates to sanitary towels which comprise an hour-glass shaped absorbent pad.
Conventional sanitary towels comprise an absorbent pad of rectangular shape which comprises absorbent fibres such as cellulosicfibres including 10 cotton, viscose rayon and comminuted wood pulp fibres. The rectangular shape of these towels does not conform well to the perineal area of thefemale and in use tend to be distorted into a bunched shape. Distortion of the towel in this manner may renderthe 15 towel uncomfortable to wear and may also undesirably reduce the surface area and absorbent capacity of the towel thereby increasing the possibility of body fluid leaking to the side edges of the towel. In orderto overcome some of the problems associated 20 with conventional sanitary towels, it is known in the art, to form sanitary towels with an hour-glass shaped absorbent pad. The hour-glass shape pad provides these sanitary towels with a narrow waist region which fits between the thighs of a female and 25 is less likely to become distorted by bunching than conventional rectangularsanitary towels. The narrow crotch region of these towels, however, has a smaller surface area for contact with the vaginal area and possibly less absorbent capacity than isdesir-30 able for sanitary towels, which may lead to the leakage of body fluid to the side edges of the towel in use. United States Patent No. 3,805,790 discloses a sanitary napkin which comprises hour-glass shaped absorbent pad which has a thicker central portionto 35 provide increased absorbent capacity in the crotch region of the pad. The absorbent pad disclosed in this patent, however, has a planar body facing surface which provides only a relatively small area at the waist region of the towel for positioning againstthe 40 vagina. British Patent No. 820,734 discloses a similar sanitary napkin in which the body facing surface at the waist region of the pad has a rounded surface which may assist in locating the surface adjacentto the vagina. The general planar body facing surface of 45 the hour-glassshaped sanitary napkins ortowels disclosed in the above prior art patents, however, does not in use ensure contact of the surface of the narrowwaist region towel against the vagina. Furthermore, there is no disclosure in these patents to a 50 sanitary towel which has an effective means to inhibit leakage of body fluid from the narrowwaist region of the pad to the side edges thereof. A sanitary towel has now been discovered which possesses these desirable properties.
55 Accordingly the present invention provides a sanitary towel which comprises an elongate hour-glass shaped absorbent pad having a thickened region intermediate both end regions and the sides characterised in that the body facing surface of the pad is 60 raised with respectto the body facing surfaces of both the end regions and sides and in that compression lines are formed longitudinally between the intermediate region and the sides thereby to inhibitthe spread of liquid from the intermediate regions to the 65 sides.
The shaped sanitary towel of the invention has several advantages over similar shaped towels disclosed in the prior art which comprise an absorbent pad which has a general planar body facing surface.
The raised intermediate region or portion of the absorbent pad allows the sanitary towel of the invention to make good contact with the vaginal area of a female and also increases the surface area of the towel at its narrowwaist region. The raised central portion of the pad can also assist in locating the towel in its correct position. The compression lines between the central portion and the sides of the pad inhibits the leakage of liquid to the side edges of the pad.
An hour-glass shaped absorbent pad is a pad which has a shape which is symmetrical about its longitudinal central axis and which is provided with a waist so that it has a pair of opposed inwardly curved sides, a narrow centrally disposed region intermediate wider end regions.
The hour-glass shaped absorbent pad used in the invention is adapted to allow the sanitary towel of the invention in use to conform to the perineal area of a female. The pad can suitably have a length of 160 to 270mm, more suitably a length of 180 to 250mm for example a length 200to 235mm.Thefront end region of the pad is preferably adapted to fitthe pubicarea of afemaletoallowthe towel in use to be located in its correct position. The front end region of the pad can suitably have a width of 60 to 120mm and preferably a width of 65 to 110mm for example a width of 75to 100mm.The narrowwaist region which lies between the inwardly curved sides of the pad is adapted to fit between the thighs of a female. This narrowwaist region can suitably have a width 30 to 70mm, more suitably a width of 35 to 55mm for example a width of 40 to 46mm.
The rear end region of the absorbent pad is adapted to coverthe perineal of a female to the rear of the vaginal area. The rear end region of the absorbent pad can have the same width as the front end region of the absorbent pad but it is preferred that the width of the rear end region is less than that of the front end region to renderthe towel of the invention more comfortable when thefemale isseated. The rear end region of the absorbent pad can suitably have a width of 50 to 110mm and preferably have a width of 55 to 100mm, for example a width of 60to75mm.
The front and rear end regions of the pad can have straight ends but it is preferred that both these end regions have rounded or curved ends which preferably merge with the inwardly curved sides to form a shape which does not have pointed sides or ends.
The front and rear end regions which are wider than the narrowwaist region of the pad tend to maintain the towel of the invention in a fixed position about the perineal area of a female and thus inhibit movement of the towel in use relative to the perineal area.
The raised central portion of the body facing surface of the pad extends through the narrowwaist region. This raised central portion is generally elongate and adapted in size to ensure that the surface ofthe towel in use will make contact with the vaginal area of a female.

The central portion provides the thickest portion of the pad. Such a central portion can suitably have a thickness of 10 to 40mm and preferably a thickness of20to35mm.
5 This portion can have a planarsurface but preferably has a rounded orconvex surface in the width direction of the pad and a flat or shallow convex curved surface in the length direction of the pad to provide the central portion of the towel with asur-10 face which can lie comfortably againstthe vaginal area of a female.
The central portion can be in a position on the absorbent pad inwhich its transverse central axis coincides with that of the waist region of the pad but 15 it is preferred that this central portion is located closer to one end region than the other to provide that region of the pad with more absorbent capacity. In a sanitary towel for normal use the central portion can favourably be located closerto the rear end re-20 gion of the pad. However, in a sanitary towel for night use the central portion can advantageously be located towards front end region of the pad.
The absorbent pad used in the invention preferably tapers in thickness from the thicker raised cen-25 tral portiontothethinnerend regionsto providethe pad with a relatively smooth profile in longitudinal direction. The edges of the pad at the backend regions can be relatively thick for example a half of the thickness of the central portion but it is preferred that 30 the edges of the pad at both end regions are relative thin for example 1 to 2mm thick so that the tapered end regions of the towel are less conspicious when worn.
The absorbent used in the invention will normally 35 comprise an absorbentfibrous material.
The absorbent pad has a compression lines formed intermediate of the sides and the central portion of the pad to inhibitthe spread of liquid to the side edges of the pad. Compression lines provides 40 the absorbent pad with linear areas of increased fibre density which absorb and wick aqueous liquids such as body fluids more rapidly than an area of less fibre density. Aqueous liquids such as body fluids contacting the compression lines on both sides of the 45 raised elongate portion of the pad will tend to be absorbed rapidly or wicked along the compression line before being absorbed into the absorbent pad thereby inhibiting the spread of the liquid to the side edges of the pad and therefore also any leakage of 50 liquid from the pad resulting therefrom.
The compression line at both sides of the central portion can advantageously extend into one or preferably both end regions of the pad to distribute liquid to these regions. It is preferred, however, that 55 the compression lines do not extend to the end or ends of the pad where they may cause leakage of liquidfromthese ends. Each compression line at both sides of the central portion can advantageously be connected to a compressed area at one or prefer-60 ably at both end regions of the pad to aid absorption of liquid atthese end regions. An end region or both end regions can have more than one compressed areaforexampletwo compressed areas each of which is connected to a separate compression line 65 so that each end of each compression line is connected to a separate compression area.
The compressed area atthe end region of the pad can advantageously be a compression line arranged to define endless path such as a closed shape for ex-70 ample a circle or ellipse which confines the spread of liquid to the area enclosed by the compression line. The compression line of closed shape can advantageously extend substantially across and end region of the pad to provide an area which inhibits the 75 spread of liquid to the edge of the end region.
In another aspect the sanitary towel of the invention has at least one compression lineformed inthe body facing surface which extends from the central portion to at least one end region of the pad to 80 spread liquid from said central portion to said end region of the pad.
The compression line or lines preferably extend from the central portion to an end region at both ends of the pad. Such compression lines can be con-85 nected to a closed shape compressed area as hereinbefore described.
The compression line or lines of the absorbent pad used in the invention will normally be a lineardep-ressed area of the pad such as a channel with for ex-90 ample a U orVshape. Acompression lineintheform of a channel on both sides of the central portion of the pad can be on either surface of the pad but is preferably that the channel is on the body facing surface of the pad. The channel shape of a compression 95 line on the body facing surface of the pad can provide a further barrier to liquid spreading from the central portion to the side edges of the pad. Acompression line can also be in the form of two channels in line with each other on opposed surfaces of the 100 pad. Compression lines in theform of a channel extending from the central portion or at the end regions of the pad, however, will normally be on the body facing surface of the pad.
The compression line in theform of a channel on a 105 surface of the absorbent pad can suitably have a depth of 5 to 20mm.
The absorbent pad used in the invention will normally have a liquid pervious cover layer on its body facing side and a liquid impermeable barrier layer on 110 its side opposite the body facing side. The cover and barrier layers preferably extend beyond the edge absorbent pad to form the peripheral edge of the sanitary towel of the invention. The inner surfaces of the cover and barrier layers can advantageously be 115 joined atthe peripheral edgeofthetowelforex-ample by adhesive or heat sealing to provide a bar-rierto liquid wicking along the cover layerto the edgeofthetowel.
The cover and barrier layers used in the invention 120 can be any of the materials normally used forthis purpose in conventional sanitary towels. Preferred materials forthe cover layers used in the invention include non-woven fabrics and plastics nets. Preferred materials forthe barrier layers used intheinven-125 tion include plastics films such as lowdensity poly-ethylenefilm.
The absorbent pad used in the invention can comprise any of the absorbentfibrous materials normally used in the absorbent pads of conventional 130 sanitary towels including cellulosicfibres such as

Such highly absorbent polymers can be in particulate form such as 5 powder orfibre or in theform of a layerfor example an impregnated or coated layer. Highly absorbent polymer in particulate or layerform can conveniently be provided within or atthe bottom surface of the absorbent pad. 10 The sanitary towel of the invention can have a fleece layerfor example rayon fleece layer between the cover layer and the body facing surface of the pad to provide a soft surface forthe towel. In preferred embodiments of the invention the bar-15 rier layer is bonded to the surface of the absorbent pad opposite the body facing surface of the padfor example by adhesive in the form of one or more spaced lines of extending in the length direction ofthe towel to stabilise the sanitary towel structure. 20 The outer surface ofthe barrier layer of thetowel can have an adhesive layerfor example in theform of a strip or pair of parallel strips of pressure sensitive adhesive which extend in the length direction ofthe towel and are covered with a release protector to en-25 ablethesanitarytowel ofthe invention to be attached to a supporting garment. The absorbent pad used in the invention can be formed by forming an hour-glass shaped pad from a preformed strip of fibrous material for example by 30 stamping method and then forming the raised elongate central portion by moulding the pad under pressure using a suitable pressure moulding apparatus. In an alternative method the shaped pad can be formed by depositing for example by air laying or 35 vacuum forming the fibrous material into a mould of suitable shape and if necessary consolidating the material underpressure. The compression lines and the compressed areas inthe shaped pad an be then formed byacon-40 ventional embossing orstamping method using a pressure device such as a roller, plate or die having projections ofthe appropriate pattern, shape and size. The compression lines at both sides ofthe central elongate portion can advantageously beformed 45 during or after moulding the pad shape by a vacuum forming process. The shaped absorbent pad can then beformed into a sanitary towel ofthe invention using a conventional method. 50 The invention will now be illustrated by reference to the following drawings in which: Figure 1 is plan view of a sanitary towel ofthe invention with its body facing upwards.
