A preferred form of the present invention will now be described with reference to the accompanying drawings in which:
a is a sectional view through the assembled panel assembly illustrating the approximate position of the underwire assembly,
With reference to
Such over the shoulder straps may however be optional as it is envisaged that the bra may also be of a strapless version. Indeed whilst reference is herein made to a bra, it is envisaged that the assembly of panels component parts and items to define such, may alternatively be incorporated into other garments such as, for example, evening dresses or bathing suits or similar.
At the ends of each of the chest bands may be fasteners 107 and 108 that are mutually cooperative to allow for the bra to be fastened about the chest of a wearer.
The bra may be seamless and made from materials at least some of which are molded or moldable and that are engaged to each other preferably at least in part by lamination.
As can be seen with reference to
The breast cup region 102 preferably defines two breast cups 109 and 110 that are adjacent to each other and between which may extend an intermediate bridge region 111. At least some of the material components defining the breast cups 109 and 110 are continuous over the entire breast cup region 102, including across the bridge region 111. Alternatively some or all of the material components may only be present at least part of the breast cups 109 and 110.
In the preferred form, at least one of the material components of the breast cup region 102 is continuous over the breast cup region 102 and preferably also over the bridge region. However in alternative forms each of the breast cups 109 and 110 may be separately predefined as for example shown in
Additional components, layers or plies of material may be provided with the materials defining the breast cup region to those herein defined.
Variations to the bra shown in
The bra 100 preferably includes at least the lower regions of each of the breast cups 109 and 110, a zone 112 defined by materials component structure and/or materials characteristics that will facilitate, when the bra is being worn, in a displacement of breast tissue at least such lower regions to encourage uplift of the breast that may thereby enhance breast uplift and/or cleavage appearance. Each zone 112 is shown in phantom in
The pocket or pockets 33 may be defined in the bra as a result of the construction of the bra. The pocket or pockets, with an air gap across, at the zones 112 may be created only once the bra is being worn by the user, again as a result of the construction of the bra.
The steps in the manufacture of the bra or in manufacture of components for a bra which allow for such a pocket to be defined, will now be described by way of example.

In
The interior panel assembly 1 and exterior panel assembly 2 are to be laminated with each other such that the foam plies 2 and 5 are proximate most each other and the fabric plies 3 and 6 face away from each other.
The precursor interior panel assembly 1 is preferably of a constant thickness. The precursor exterior panel assembly 4 is preferably of a constant thickness. However prior to their lamination together one or both of the panel assemblies 1, 4 is preferably modified. Such modification is to introduce a variation in thickness in the panel assembly 1 and/or 4 at appropriate regions that, with subsequent processing, will lead to a variation in density.
With reference to
The zone 8 at each breast cup region 109 and 110 is preferably of a plateau shape. The plateau region 8 is of a greater thickness than the surrounding panel region or regions. With reference to
The region of increased thickness may include a gradual transition between the thinner regions of the foam ply 5 and the zone of increased thickness 8 at least about some perimeter regions of the plateau. As can be seen with reference to
In addition or alternatively, the interior panel assembly 1 may be modified in a similar manner to introduce zones 11. The zones 11 where both the exterior and interior panel assemblies are modified to introduce the zones 8/11, are preferably of a shape and size that is scaled down from the plan shape of the zones 8 of the exterior panel assembly 4. Such scaling is preferably in both axes of the Cartesian plane and is preferably done so that the zones 11 do not extend beyond the boundary of the zones 8 once the external and internal panel assemblies are laminated with each other.
The exterior panel assembly 4 with its modified thickness may be introduced into a molding device consisting of upper and lower mold portions 14/15 for the introduction of the breast cups shape. The exterior panel assembly 4 is positioned in the molding device such that the foam ply 5 will be positioned on the concave side of the molded panel assembly and the fabric ply 6 is on the convex side.
A molded exterior panel assembly 4 is shown in
After the forming of the three dimensional breast cups, underwire assemblies may be placed on the foam ply 5 at or immediately adjacent the lower regions of the breast cups. The underwire assembly may consist of a plastic strip and/or a metal wire that may or may not be encased within a sock such as a fabric sock. Preferably two underwires 16 are provided, one for each breast cup.
The placement and securing of the underwire 16 and other components may occur before the breast cup region 102 is trimmed from the remaining peripheral portions of the exterior panel 4 or after.
With reference to
The underwire or underwire structure 16 is preferably held in place with the panel 4 by the use of an adhesive. Such an adhesive may be provided to at least tack the underwire in place.
With reference to
The gauze may also be applied by the use of an adhesive such as an adhesive spray or adhesive tacking, to locate the gauze in position relative to the external panel 4.
With reference to
In other embodiments of this invention, the components 16, 17, 19 and 20 may be placed in different order than those described herein with reference to the drawings.
With reference to
Alternatively, the same set of materials 16, 17, 19 and 20 can be glued onto the foam layer 2 of the interior panel assembly 1 before lamination with the exterior panel 4.
Modified panels 1 and 4 are then able to be laminated together in an overlying manner as for example shown in cross-sectional side view in
There are hence preferably two molding actions (as described with reference to
Lamination of the panels 1 and 4 in their condition described with reference to
Save for the upper perimeter of the original plateau area(s) 8 of the exterior panel 4, the perimeter of the original plateau area at the exterior panel 4 may be laminated at the perimeter of the original plateau area 11 at the interior panel 1. Since the original plateau area(s) 8 at the exterior panel 4 covers preferably more than half of the original plateau area 11 of the interior panel 1, the upper perimeter of the original plateau area 11 at the interior panel 1 is laminated with the original plateau area 8 of the exterior panel 4 (at around the middle part of the original plateau area of the exterior layer).
Each of the two molding actions (i.e. the molding action in
Preferably the predetermined shape formed at each breast cup region of the exterior panel by the molding of the shaved exterior panel in
Since the predetermined shape at each breast cup region of the molded exterior panel and the predetermined shape at each breast cup region of the molded interior panel preferably does not change during the laminating action in
Thus the shape of the pocket 33 is formed by the molding action in
The plateau 8 of the foam ply 5 of the pre-molded exterior panel 4 has the main function of keeping the breast cup region 102 in its intended shape particularly from an external view point. Since the density of the foam at where the plateau 8 was defined and after being molded, will be higher the foam thereat will be harder than the foam at the remaining part of the breast cup region 102. As such, when the bra is being worn, any change of shape of the breast cup region 102 will be resisted. This means that the outward aesthetic appearance can to a large extend be maintained.
The higher density foam sections of the exterior panel and the inner panel are stiffer than the lower density sections of the same panels. The stiffness tends to attribute to the maintenance of the pocket shape as much as possible when the bra is worn. The higher density foam sections at both the exterior panel and the inner panel (rather than just at one of the panels only) are desired primarily for providing a shape-keeping effect to the pocket. Therefore, it is not expected that an exterior most ply can provide a better shape-keeping effect to the pocket 33, although such exterior most ply may obscure any visually undesired deformation of the exterior and/or interior panels.
A change of shape of the breast cup region 102 may be caused by different forces applied on the bra when the bra is being worn.
Further, after lamination of the exterior panel 4 and the interior panel 1 together (
As the denser foam area at the exterior panel 4 is relatively hard it may provide a shape-keeping function for the brassiere.
The foam close to the neckline of the exterior panel may be of a lower density because there is not much force being applied thereon when the bra is being worn.
When the bra is worn, the breast cup region at the pocket 33 is pressed by the breast, thereby creating a force pushing both ends of the underwire (which was in its natural shape before the bra is worn) towards each other and also creating a force pulling the back straps towards this region. However, since the underwire and any other elastic components of the bra surrounding the chest and back of the wearer tend to return to their natural shapes, the shape of the pocket can be maintained as much as possible and thereby providing good support of the breast.
The denser foam area at the interior panel 1 (i.e. the original plateau area 11 at the foam layer of the pre-molded interior panel 1) may keep the pocket 33 in shape as much as possible since its higher density regions make the foam harder. There is no need to have the denser foam area of the interior panel bigger than the denser foam area of the exterior panel because any change of shape of the breast cup region at the interior panel when the bra is being worn should not be visible.
Because of (a) the stretching of the non-laminated area of each bra cup region of the interior layer towards the laminated area of the bra cup region of the core assembly and (b) the stretching of the said non-laminated area generally between two ends of the underwire structure resulting from the stiffness of the underwire structure, the non-laminated area of each bra cup region of the interior layer bulges towards the skin of the wearer, creating a hollow uplifting bra pad.
Given that the pocket does not include a pouch or pad, it will be lighter than a bra that does.
The fabric material used may be of a material known by model number CMF-7440MU of Friendly Foundate Ltd. This fabric is made of 80% Tactel and 20% lycra. The fabric layer 9 may have a make-up of approximately 80% Tactel 40d/34f and 20% lycra 40d and of a weight of, for example, 190 g/m2.
The foam used is preferably a polyurethane foam of a precursor density of, for example, 30-40d.
Adhesive used may be of a kind such as RM-30 of Ultra Energy Adhesive Trading Co., Ltd.
The bridge fabric may be 7118 of Goldspring Co. Ltd. It is preferably a piece of gauze which is 100% nylon.
One or all the molding processes occur preferably at an upper mold temperature of 180° C. to 200° C. and the lower mold is preferably of 180° C. to 200° C. The dwell time holding the mold portions together is for example 120 seconds.
