   TECHNICAL FIELD 
   The present invention relates to breast cup construction. In particular although not solely it relates to breast cup construction for garments such as a brassiere. 
   BACKGROUND ART 
   Numerous designs of brassiere exist. Designers over the years have also paid significant attention to the shape of the breast cup of brassieres. 
   Changing fashion trends and new materials have over the last one hundred years, seen significant changes and advancements in brassiere design where focus has been on numerous important factors such as comfort, shape, shape enhancement, stability and general aesthetics, and manufacturing benefits. 
   Brassieres which are designed to enhance the bust line or cleavage of the wearer of the bra have also come in many different shapes and designs. By way of example U.S. Pat. No. 3,834,397 discloses a brassiere where the cup construction is provided with padding to force upwardly, the lower regions of the breast. 
   Breast cup constructions also vary. By way of example, U.S. Pat. No. 3,780,741 illustrates the construction of a breast cup wherein two panels are provided to define the breast cup and which have been sewn together in a manner to define a curved seam joining the two panels together and thereby defining a breast cup construction of a specific volume and shape. 
   Furthermore, and sometimes in addition with the inclusion of padding in a bra, many bras for the enhancement of the bust line, will include an underwire. This underwire normally runs from or approximately to the point where the shoulder straps of a bra connect to each of the cups, and runs around the outer and lower perimeter of the cups. Half cup underwire brasseries are also known, where the underwire extends only along a portion of the outer perimeter of the brasserie. 
   The provision of an underwire, leads to problems in terms of comfort to the wearer and can also add to the cost of manufacture. They can also be easily damaged when being washed and machine dried. 
   Accordingly it is an object of the present invention to provide a breast cup construction without an under wire or padding, which enhances the bust line of the wearer of the garment which incorporates such a breast cup construction. 
   It is also an object of the present invention to provide a brassiere construction which enhances the bust line of the wearer without the need to use underwire or padding techniques. 
   It is also an object of the present invention to provide a breast cup construction and garment incorporating such which will at least provide the public with a useful choice.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   With reference to  FIGS. 1 and 2 , the present invention incorporates a breast cup construction in a garment such as, for example, a brassiere or bikini top or the like. The present invention however can also be incorporated in other garments such as in a dress (as per for example  FIG. 6 ) or the like. The breast cup construction avoids the need for the use of an underwire or padding in the cup as a result of the manner in which the at least three regions preferably defined by panels  7 ,  8 ,  9  or the breast cup construction are provided. 
   Whilst hereinafter, our focus on the description is in relation to brassieres incorporating the breast cup construction of the present invention, it is to be appreciated that it is not limited to brassieres only. 
   In a first preferred construction of the cup as defined in the figures, the brassiere includes the breast cup construction  15  as appropriately incorporated in a support providing structure. The support providing structure provides shoulder engaging straps  16  and side panels  18  extending to a strap  19  to locate around the chest of the wearer. 
   Each of the two cups of the brassiere as shown in  FIG. 1  includes an outer most edge  1  and an inner most region  5 . In  FIG. 1 , the inner most region  5  of each of the two cups of the brassiere coincide. In  FIG. 2  the inner most region of each cup construction are separated by an optional band  14 . 
   Each cup has at least three panels, a lower most panel  7 , an intermediate panel  8  and an upper panel  9 . The upper panel  9  may be the uppermost panel or may have thereabove a further upper or uppermost panel  10 . This panel  10 , (or  14 ) is optional. 
   The lower most panel  7  has an upper joining edge  20  of a predetermined curvature. With reference to, for example,  FIG. 3  which shows each of the three panels in a lay flat condition, this upper joining edge  20  of the lower most panel  7  is curved. The intermediate panel  8  has a lower joining edge  21  which is also of a predetermined curvature and is secured to the upper edge of the lower most panel  7  to define a seam  2  as shown in FIG.  1 . 
   The intermediate panel has an upper joining edge  22  of a predetermined curvature which is secured to a lower joining edge  23  of the upper panel  9  to define a seam  3 . Each of the joining edges of the lower intermediate and upper panels are of a substantially similar length to the edge to which it is joined of the adjacent panel(s). This is not necessarily the case when the panels are in a lay-flat condition and indeed in  FIG. 3  the upper and lower edges of each panel are not of the same length. 
   In the most preferred form each of the seams  2  and  3  (and preferably also seam  4  in the option where a uppermost panel  10  is provided as per  FIG. 1 ) has the inner most terminus preferably at the inner most region  5  of the cup preferably they are co-terminus. The outer terminus of each of the seams  2  and  3 , are at the outer edge  1 , of the cup and are at different locations. The outer edge  1  is preferably of a smooth and continuous curve and extends from its inner region  5  to an upper most region  6  of the outer edge  1  at the point where or proximate to the point where the shoulder strap is to engage with the cup. 
   In the form as shown in  FIGS. 1 and 2 , the outer most terminus  11  of the seam  2  of between the lower and intermediate panels  7 ,  8  is substantially horizontally in line with its inner most terminus. The outer most terminus is, broadly speaking, provided in a region of the outer most edge  1 , where the curvature of the outer most edge  1 , running from the top part of the upper most edge towards the inner most region  5 , is back towards the inner most region  5 . A force F I  (with reference to  FIG. 4 ) which is lateral to the force F c  to the curvature of the outer most edge at point  11  is inwards and upwards, which is the desired direction of pressure applied to the breast. The support and application of the force along the outer perimeter is provided at the top of the outer perimeter line to which the shoulder strap is attached. A distributive force illustrated by the plurality of arrows in  FIG. 4  extending from the outer perimeter line is also resultant on the breast cup construction. Because of the outline of the perimeter, the net force as a result of the distributive is both upwardly and inwardly thereby enhancing cleavage. 
   The outer most terminus  12  of the seam  3  joining the intermediate and upper panels  8 ,  9 , is at or towards the upper most point  6  of the outer edge  1  of the cup. This is at or approximate to where the shoulder strap  16  engages with the cup of the brassiere of FIG.  1 . The force of the support provided by the shoulder strap is in a generally upward direction as indicated by arrow F u . At the point where the terminus  12 ,  13  are located, the curvature of the outer edge  1  is, with respect to the vertical, either substantially vertical or in a direction towards or away from the inner most region  5 . The force F c  at the terminus  12 , is hence at least upwardly but preferably also inwardly. Such an inward angling of the outer edge hence assists the displacement of the breast at this region inwardly hence increasing the bust. An outward angling would reduce the projection of the bust.  FIG. 7  clearly illustrates the curvature of the outer edge, with respect to the vertical. With reference to  FIG. 7 , because of the force F c  applied along the outward edge  1  the resultant force F c  on the terminus  12  also has an inward component encouraging the movement of the bust line both upward and inwardly. 
   The outer terminus  12  of the scam  3  is vertically higher than its inner terminus. The lower most panel  7  is joined to the structure providing means  18  at the outer most edge  1  of the cup to extend across the lower most point  24  of the outer edge  1 . However the lower most point of the outer edge  1  is slightly but not significantly lower than the inner most region  5  of the cup. 
   The outer edge  1  of the cup, is shaped to have curvature so that when the shoulder strap is tightened by adjustment, the bust moves across and upwards, generally in direction F, to the desired condition. The seam  2 , apart from strengthening the cup structure, when the bust moves in its upward position also helps to support the lower area of the bust. The seam  3  forms the shaped area of the cup with seam  2  contributing to the cup contour, and support. The underarm side support  18 ,  19  can be either a broad band, or straps that may have adjustment to a comfortable position. The unique formation of the invention provides the visual appearance that there is an increase in breast size. It was further realised that as the bust tends to move to the side by its own weight, that the construction of the cup should be based on the side contour of the bust. To obtain a greater bust exposure the optional panel  10  may be folded back about seam  4 . To provide the function of a sports bra to cater for larger busted women who do not want emphasis on cleavage, the upper most panel  14  can be changed by bringing it down through the front of the bra. This provides a visually attractive and comfortable bust support enabling the larger busted women, to engage in sports or other activities, or the like. The cup formation would also be suitable for the smaller or medium busted woman who did not want emphasis on cleavage. 
   When a grading of a larger cup size is necessary it will mean a scaling of the cup size, however the pressure points remain the same in proportion, and the seams  2  and  3  are preferably still interconnected at the inner region of cup. Therefore regardless of cup size the fundamental principals of the invention remain constant. The end result of the invention is to produce a more natural rounded cleavage that is not obtained with others on the market including padded bras that require an artificially enhancement to obtain cleavage. 
   When the bust is placed in the cup it is displaced inwards and upwards by seam  3  which has its inner and outer terminus preferably set at 45° to the horizontal. Seam  1  has a resultant force, due to the outer seam control at point  11  that lifts at least that end of the seam  2  up and across. This moves the bust upwards and across producing the unique end result of our invention as a naturally rounded cleavage. Seam  1  on its own will not produce the same effect, unless it acts in conjunction with seam  2 . 
   The resultant shape of seam  2  as a factor of the curvature of the joining edges  20 ,  21  is such that there is a reduction in volume provided in the lower region of the cup, which forces the breast tissue upwards. 
   The seams of the present invention are preferably seams that are sewn, to define the join between adjacent panels. The material that is used for the cup construction is preferably a flexible fabric. In order to further enhance the effect of the breast cup construction, the seams are preferably of a nature which defines a raised ridge on the interior of the cup. The sewn seams are therefore of a kind which provide this enhancement of a ridge which improves the contact and therefore the transfer of retaining and displacing force onto a breast. Since the panels of the fabric are of a flexible and for example an elastic material the seams provide lines of rigidity which at least along the direction of the seams, the material becomes substantially non extendable. The seams hence define at least some structural rigidity to the three dimensional form of the cup and thereby and in particular as a result of their placement, can provide a reactive force against the outward pressure of the breast to thereby force the breast in those particular areas back towards the body of the person and simultaneously project the breast upwardly and inwardly to provide cleavage. The lower most panel can be shaped so as to reduce the volume of the cup at its lower regions to thereby displace breast tissue towards higher regions of the cup volume. The seam between the intermediate panel and the upper panel may provide a similar effect and because of its angling at preferably 45° it also assists in the displacement of the breast inwardly. 
   In a second embodiment of the present invention, it is envisaged by the inventor that a breast cup construction may be provided by at least one panel which has been moulded to a 3-D cup shape. To provide structural strength to a moulded panel of flexible material the at least one panel is provided with lines of stitching provided in accordance to what has hereinbefore been described with reference to the seams in the first preferred form of the present invention wherein the cup construction is made from at least three panels. The lines of stitching in a moulded version of the breast cup construction of the present invention hence provide the structural rigidity to the breast cup construction in those regions where it is desired in order to provide the effect of enhanced cleavage. Where the breast cup construction in the second preferred form of the invention is provided by a single panel a first and second line of stitching may be provided wherein the first line extends between the lower and intermediate region (synonymous with the lower and intermediate panel) and the second line of stitching extends between the intermediate and upper region (synonymous with the intermediate and upper panel as previously defined). 
   It is envisaged that alternative ways of forms the seams may be provided. The material that is used may be of a plastics kind wherein heat welding or the like may be provided for joining the seams. Alternatively adhesion may also prove successful. 
   The lower waist panel is of an elongate shape and extends in a generally horizontal direction. 
   The intermediate panel is preferably triangular in shape and its upper edge is concave whilst its other two edges are convex in curvature. 
   The outer perimeter of the cup construction is curvilinear and preferably substantially convex. It extends from an inner region between said two cups of a brassiere to an upper region where or from which or proximate to which the shoulder straps will attach.
