## Background
CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority, under 35 U.S.C. §119(e), to U.S. Provisional Applications Nos. 61/129,458 filed Jun. 27, 2008, and 61/129,661 filed Jul. 10, 2008, both entitled “Open Front Undergarment and Method of Making the Same,” each of which is herein incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an undergarment. More particularly, although not exclusively, the present invention relates to an open front undergarment or brassiere that partially circumscribes the body of a wearer. The present invention also relates to a method of manufacturing the undergarment.
2. Description of the Related Art
Undergarments such as brassieres come in a variety of styles. Two of the styles include the strapped and strapless brassieres. The strapped brassiere has two cups for breasts, a center panel or gore, a band for running around the torso under the bust, and a shoulder strap for each shoulder. The strapless brassiere has two cups for breasts, a center panel or gore and a band for running around the torso under the bust, but no shoulder straps. Other variations of the strapped and strapless brassieres include, for example, adhesive, shelf, convertible, cupless, balconette, full support, gel, and minimizer; however, the aforementioned brassieres either encircle the torso under the bust or fail to provide sufficient support members, such as for example, a support member across the back. Further, existing brassieres are usually fastened with a hook fastener on the band, typically at the back or in the front, between the cups. Other brassieres that encircle the torso are worn by being pulled on over the head and have no fasteners. There is a need for a brassiere that provides an opening in the front to accommodate clothes that are open in the front below the bustline, yet provides support to the breasts through the wearer's back.
SUMMARY OF THE INVENTION
The present invention relates to a new type of brassiere that is open in the front, whereby a supporting or rear band only partially circumscribes the torso of the wearer, and the cups are disposed at the ends of the rear band and separated from each other. The present invention takes into consideration that a wearer of the invention may be dressed in a garment that has a low front wherein the garment has an opening that extends below the bustline. The present invention also takes into consideration that the wearer desires a brassiere that provides both support from the back and an unobstructed space between the cups. The present invention further takes into consideration that a wearer of the invention may want to reduce the amount of material on the torso and in the breast area for ventilation between the breasts. As such, the brassiere of the present invention allows the wearer to cover and support the breast, so that the breast area can be ventilated and still supported, and that the wearer can wear clothing of a variety of styles.
One embodiment of the present invention includes a strapless brassiere having an open front. Another embodiment of the present invention includes a strapped brassiere having an open front and at least one shoulder strap that extends from the front to the back of the brassiere. A further embodiment of the present invention includes a variety of cup shapes for altering the appearance of the shape of the breasts, such as, for example, a pushed up shape for greater cleavage.
The brassiere of the present invention can also include a flexure region in the rear band. The flexure region can include a linkage or a hinge to facilitate dressing and allow flexure of the brassiere with the back of the wearer.
Example embodiments of the present invention will now be described in accordance with the above advantages. It will be appreciated that these examples are merely illustrative of the invention. Many variations and modifications will be apparent to those skilled in the art.

DETAILED DESCRIPTION OF INVENTION
FIGS. 1 to 8 illustrate and open front undergarment such as a brassiere 2 according to an embodiment of the present invention. The front view of the brassiere 2 shown in FIGS. 1 and 2 illustrates a pair of cups 4 extending from the ends of and supported by a rear band 6. The cups 4 directly support the breasts and the rear band 6 provides additional support to the cups and the overall brassiere 2. The cups can also conform to or are configurable to the shape of the wearer's breast. Further support can be provided by side portions of the frame which extend in a direction perpendicular to the longitudinal axis of the frame, as discussed below. The side portions of the frame can be integral with the frame or reinforced with added material. The cups 4 and rear band 6 are formed and reinforced by a frame 10, shown in FIG. 3, and a brassiere cover 3 is fixed to and extends over the entire frame.
FIG. 2 shows the cups 4 extending from opposite ends of the rear band 6 and the frame being curved along a longitudinal axis thereof to form the brassiere as an arcuate member. A concave portion of the frame defines an inner surface thereof and a convex portion of the frame defines an outer surface. The inner surface of the frame facing an inner surface of the cups The cups 4 are separated from each other and are designed to be unconnected and independent of each other. The arrangement of the cups in the present invention allows an open front garment to be worn without the brassiere being seen. The cups 4, although shown as having a circular shape, can be formed in any shape including semicircular as shown in FIGS. 14 and 15, for example. The cups 4 enclose the breasts and provide a smooth line where the material at the upper edge of the cup ends.
The cover 3 can be formed from any material including, but not limited to fabrics such as cotton, polyester, spandex, lace, rayon, silk, or any combination thereof. For example, a combination may include natural and synthetic materials or stretch fabrics such as two-way stretch nylon/Lycra satin.
The cover 3 of the present invention can be stretched over the frame 10 as shown in FIG. 3. The frame 10 is formed from an underwire 10a and an overwire 10b. The underwire 10a forms the lower portion of the brassiere 2 and the overwire 10b forms the upper portion. As such, the cups 4 and rear band 6 are bounded by the frame 10, which provides an outline of the brassiere. The frame 10 can be bent along its longitudinal axis to form an arcuate member that is contoured to the shape of a torso.
FIG. 3 shows the rear view of the brassiere 2, wherein the frame 10 is shown as curved along its longitudinal axis, at flexure region 8, from the outer surface to the inner surface of the brassiere. The flexure region 8 can be provided along a central portion of the rear band 6 to follow the curve of the wearer's back for a close and comfortable fit. The flexure region 8 allows the rear band 6 to flexibly move with the flexing of the wearer's back. Alternatively, the brassiere 2 can have a flexible frame that accommodates the natural flexure of the wearer across the upper torso above the bustline. Further, the flexure region 8 can be made of a material different from material of the underwire and overwire.
In FIG. 4, a cut-away portion of the brassiere 2 shows the interior of the cups 4 and the frame 10 including the underwire 10a and the overwire 10b. The underwire 10a is a rigid or semi-rigid band that runs along the lower perimeter or edge 7b of the brassiere 2 and forms the lower portion of the rear band 6 and the cups 4. The underwire 10a supports and uplifts the bustline. The overwire 10b is a rigid or semi-rigid band that runs along the upper perimeter or edge 7a of the brassiere 2 and forms the upper portion of the rear band 6 and cups 4 to provide a gripping force of the brassiere on the torso.
FIG. 5 illustrates a cross-sectional area of the brassiere, through 5-5 in FIG. 4. The cross-sectional view shows the underwire 10a and overwire 10b of the frame 10 within the cover 3. The underwire 10a and overwire 10b are arranged along the perimeter of the cover 3 to shape the brassiere 2. The underwire 10a and overwire 10b can be secured into the cover 3 by an adhesive, sewing, a fastener or other securing means.
The underwire 10a and overwire 10b can be formed of a metal wire, such as a steel wire. The underwire and overwire are not limited to steel and can be formed of any elongated strand of drawn metal having ductility. In addition, the underwire and overwire can be formed of any metal wire coated with plastic. An alternative material for the underwire and overwire includes a polymeric material, such as plastic. The frame 10 is not limited to an overwire and underwire alone. The rear band 6 can also be made from a material different from that of the frame portion around the cups 4. For example, the rear band 6 can be made from elastic, rubber or other expandable material, while the cups 4 are made from the underwire and overwire. In addition, the rear band 6 can include a combination of the underwire and overwire and elastic, rubber or other expandable material. Materials in the present invention can be joined by adhesive, sewing, molding or other fastening and joining means.
The underwire 10a and overwire 10b can support the weight of the material used for forming the cover. Although the underwire 10a and overwire 10b are shown in the figures as having a rectangular cross section, the wires can have any cross section including oval or round, for example.
A slip-resistant band 5 shown in FIG. 5 can be affixed to the inner surface of the brassiere 2 on the cover 3 proximal to the upper and lower perimeters 7a, 7b. For example, as shown in FIG. 5, the slip-resistant band is shown as a continuous band on the inner surface of the rear band 6. The slip-resistant band can also extend around the cups as shown in FIGS. 7 and 8. The slip-resistant band 5 controls the position of the brassiere on the torso. The slip-resistant bands 5 can be formed from any material including, but not limited to, silicon, rubber or an adhesive. As shown in FIG. 5, a pair of slip resistant bands 5 can be located proximal to the outer edges of the brassiere. As an alternative to a continuous band, the slip resistant band can be segmented along the inner surface of the brassiere.
FIG. 6 illustrates a side view of the brassiere 2 according to an embodiment of the present invention. The sides 9 are uniform in height along the entire length of the brassiere 2 because the underwire 10a and the overwire 10b are equi-spaced throughout the rear band 6. The cups 4 can have a height that is greater than the height of the sides 9 and rear band 6. The lower perimeter 7b of the brassiere 2, as shown in FIG. 6, is parallel with the upper perimeter 7a. The side portion 9 of the brassiere can have the same height as the rear band 6 for uniformity of the frame 10 around the wearer's back. In order to maintain the uniformity, side portions can include reinforcing panels, such as reinforced fabric or wire that may be fitted to extend between the upper 7a and lower 7b perimeters of the brassiere anywhere along the length thereof. The reinforcing panels prevent the underwire 10a and overwire 10b from collapsing together.
In operation, the rear band 6 is designed to extend horizontally across the torso of the wearer along the wearer's back and partially around the front of the wearer so that the cups 4 remain separate and unconnected. The rear band 6, sides 9 and cups 4 can be held in place by the slip-resistant bands 5.
The brassiere 2 can have a shape that conforms to the torso of the wearer. For example, the shape of the brassiere can be oval, round, or rectangular as viewed from the top or bottom as shown in FIGS. 7 and 8. The frame 10 can be contoured toward the center of the brassiere so that the underwire 10a can apply pressure to the bustline for a snug fit. The flexure region 8 is shown as contoured toward the back of the wearer. The slip-resistant bands 5 are located on or adjacent to the inner surface upper and lower perimeters 7a, 7b of the brassiere to control the vertical and horizontal position of the brassiere on the torso.
A second embodiment of the present invention shows a brassiere 20. In this embodiment, a padding 16 is disposed on an inner surface of the cups of the brassiere 20. The padding 16 can be formed from any material including cotton, fiberfill, silicone, sponge, gel or any other fill material. Further the padding 16 can be coated with an adhesive material on an outer surface thereof for adhering to the breasts. FIG. 9 illustrates a cut-away portion of the cups 4 showing the padding 16. FIGS. 9 and 10 illustrate a pocket 14 disposed on an inner surface of the cups 4 and the padding being disposed within the pocket 14. The padding 16 can be removably held in the pocket 14 having an open top, as shown in FIG. 10. The pocket 14 can be open at one end to allow the selective introduction of the padding 16. Alternatively, the padding 16 can be affixed to the inner surface of the cup 4 or fixed within the pocket 14 by means of sewing, an adhesive or other fastener. The pocket 14 can be connected to a lower portion of the cup 4, above the underwire 10a. Although the figures illustrate the pocket 14 as open at a top end, the pocket can be open at any end, such as a side or orthogonal end, to allow the padding 16 to be inserted into the cup 4. The pocket 14 is disposed between the slip-resistant bands 5 and the padding 16 can fit fully within the pocket or extend outward from a top of the pocket as shown in FIG. 10. The padding 16 serves to push the breast upward and create cleavage or to create a more curved silhouette in the area of the cups 4.
In a third embodiment of the present invention, an alternative brassiere 22 in FIGS. 11 and 12 is shown. The brassiere 22 is similar in structure to the brassieres 2 and 20 shown in FIGS. 2 and 9. The brassiere 22 can include shoulder straps 24 that extend from the rear band 6 to the cups at the open front. The shoulder straps 24 can be adjustable with adjusting members 26. The adjusting members 26 can include a buckle, Velcro® or other means for moving and securing the adjusting member along its length. The shoulder straps 24 can be made from materials such as elastic or a fabric such as cotton, and can be lined with slip-resistant bands 5 on an inner surface facing the cups 4 and rear band 6.
In a fourth embodiment of the present invention, an alternative brassiere 28 in FIG. 13 is shown. The brassiere 28 is similar in structure to the brassieres 2 and 20 shown in FIGS. 2 and 9. In this embodiment, a single shoulder strap 30 extends from one side of the rear band 6 of the brassiere 28 to a cup 4 on the front, diagonally across the arc formed by the curvature of the frame 10. The brassiere 28 can be worn under clothing styles such as halter tops or single shouldered tops to provide additional support to the cups 4. The shoulder strap 30 can be adjusted with an adjustment member 26.
In a fifth embodiment of the present invention, an alternative brassiere 32 in FIG. 14 is shown. The cups 34 of the brassiere 32 are in the form of semi-circles or demi-cups. The demi-cups shown in FIG. 14 allow low collar or low cut garments to be worn without the brassiere being seen. The demi-cups may be designed to provide lift, similar to a push-up brassiere. As such, the overwire can be omitted for additional lift.
For additional support in the brassiere 32 in FIG. 14, reinforcing members, such as a reinforcing panel 36 and reinforcing strip 38 can be added. The reinforcing panel 36 is located between the cups 4 and the rear band 6. The reinforcing strip 38 serves to keep the reinforced panel 36 in alignment with the rear band 6 and the cups 4. The reinforcing panel 36 can be made of elastic and the reinforcing strip 38 can be made of folded fabric to provide rigidity or a rigid plastic material, for example, covered with fabric.
A sixth embodiment of the present invention shown in FIG. 15 illustrates a brassiere 40. In the brassiere 40, the rear band 6 extends directly to the cups 42, which are designed as elongated demi-cups. As described above, the demi-cups allow low collar or low cut garments to be worn without the brassiere being seen and can provide lift, similar to a push-up brassiere. In order to increase the amount of lift, the overwire can be omitted.
FIGS. 16 and 17 illustrate a seventh embodiment of the present invention with a brassiere 44. Brassiere 44 is similar to the brassieres in FIGS. 1 to 13, in that it includes at least the flexure region 8 at the center of the rear band 6. For further flexing of the rear portion of the brassiere, a hinge 46 can be affixed to the center of the rear band 6. The hinge can be a butterfly hinge as shown, for example in FIGS. 16 and 17, or any pivoting member that allows for the flexure of the torso in a direction orthogonal to the longitudinal direction of the rear band 6.
FIGS. 18, 19 and 20 illustrate an eighth embodiment of the present invention with a brassiere 48. As shown in FIG. 18, the brassiere 48 has a single or solo wire 50 provided in the rear band portion of the frame. The solo wire is a single wire that has a width that extends the entire width of the rear band 52, such that only a single band is need for support as opposed to the combined underwire and overwire. The solo wire supports the brassiere 48 in the rear band 52 across the wearer's back. The underwire 54a and overwire 54b remain around the cups 4 as shown in the cut-away view of FIG. 19. The solo wire 50 can be formed of a metal wire, such as a steel wire. The solo wire 50 is not limited to steel and can be formed of any elongated strand of drawn metal having ductility. In addition, the solo wire 50 can be formed of any metal wire coated with plastic. An alternative material for the solo wire 50 includes a polymeric material, such as plastic. The plastic can be injection molded to form the rear band 52 and the underwire 54a and overwire 54b. The solo wire 50 can support the weight of the material used for forming the cover 3. Although the solo wire 50 is shown in the figures as having a rectangular cross section, the wires can have any cross section including, for example, oval or rounded. A further alternative material within the rear band 52 can be elastic, rubber or other expandable material, while the cups 4 are made from the underwire and overwire. In addition, the rear band 52 can include a combination of the solo wire 50 and elastic, rubber or other expandable material. Materials in the present invention can be joined by adhesive, sewing, molding or other fastening and joining means.
