DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS OF THE INVENTION

(9) The present invention is now described below in detail with reference to the figures.

(10) Turning first to FIG. 1, there is shown some preferred examples of the pattern design for making the 3-dimentional brassiere support of the present invention. Additional pattern examples can be found in FIG. 2. It is understood that the examples provided on FIGS. 1 and 2 are for the purpose of illustration of the present invention, but not as the limitation of its scope. The design and selection of the pattern is an important feature in practicing the present invention, because a proper pattern provides both adequate support to the breasts and comfortable wearing experience. As it is noted from the samples provided in FIG. 1 and FIG. 2, a proper pattern should be in a general X shape, which can be a single piece or can be formed from two pieces with some overlapped area as shown in patterns F-G of FIG. 2. Other variations of the X shape are possible and may also provide satisfactory results. For the purpose of this invention, the X-shape means a shape having four forks joined at a joint point, with two left forks supporting the left cup and two right forks supporting the right cup. The X shaped support of the present invention is preferably made of 100% EVA (Ethylene Vinyl Acetate), which can be purchased in the market as common commodities. Other materials may also be used, such as, for example compressed polyurethane, fiberfill or similar materials that can form a 3-dimentional curved shape after the process of heat or cold molding or injection molding. In the particular embodiment where the EVA sheet (which can be in a form of net or mesh) was used as the starting material, the EVA sheet is cut into a designated X shape by any cutting technology used in the art, for example, manual-cutting, die-cutting (or stamp cutting), laser-cutting or CNC (computer numerically controlled) cutting. The thickness of the X shaped support can be from 0.1 to 200 mm, measured before or after compression. A person of ordinary skill in the art is capable of selecting a proper material of a proper thickness and a cutting method according to the specific circumstance, which are not limitations to the scope of the present invention. The detailed steps of making X-shape supported brassiere are described in the following.

(11) Making Outer and Inner Cup Panel:

(12) A fabric sheet is laminated to a foam sheet to form an outer cup panel and/or inner cup panel. As an example, the fabric sheet is a 100% knitted polyester fabric and the foam sheet is 100% polyurethane foam. Of course, other materials may also provide satisfactory results as the fabric sheet and the foam sheet, the selection of which are within ordinary skill of the art. The outer cup panel and the inner cup panel may be made from the same laminated panel. Or, as shown in FIG. 3, outer cup panel A and inner cup panel B may have different fabric linings (A31, B31) and/or different foam sheets (A32, B32). The outer and inner cup laminated panel may be trimmed (by manual, CNC, or die cutting) to a suitable size and shape prior to proceeding to the next step.

(13) Molding Outer Cup Panel:

(14) The outer cup panel is placed between the male and female of a heated aluminum mold with the temperature adjusted according to the type of material used in the panel. The male and female molding halves are then closed. After a designated time passes, the halves are opened. A pair of molded cups (which may also be made one at a time) is formed. The FIG. 4 shows that a flat laminated outer panel 41 is molded into a pair of brassier cups 42.

(15) Molding X-Shaped Support Between Outer and Inner Cup Panels:

(16) Adhesive is applied on the foam surface of molded cup of the outer cup panel made from the above step, on one or both surfaces of the X-shaped support, and on the foam surface of the inner cup panel. Next, the X-shaped support is positioned on the foam surface of the inner cup panel to form a flat assembled support-inner panel (alternatively, the X-shaped support may also be positioned on the foam surface of the outer cup panel covering part of the rim area of the molded cups thereon). Then, the molded outer cup panel is placed on the female of a heated aluminum mold, followed by positioning the assembled support-inner panel on the molded outer cup panel in a way that the X-shaped support is between the outer and inner cup panels. The male of the mold is then put in position to clamp the molded outer cup, the X shaped support and the inner cup panel together for a predetermined time to produce a finished molded cup shape. FIG. 5 is a 2-D view showing the relative positioning of the X shaped support 51 on the inner cup panel 52, on which engraved lines 53 are provided for final trimming. After trimming along the engraved lines by scissors, band-knife, sewing machine or stamp cutting, finished brassiere cups are formed as shown in FIG. 6. Because of the plasticity of the material of the X-shaped support, once molded, it assumes a conforming 3-dimensional shape within the finished molded cups without exerting any residual torque. While not being bound by theory, it is believed that this makes possible that both breasts can be supported by a single integral support without causing any uncomfortable feel. FIG. 6 specifically shows the, right, cup 60 and the left cup 61 of the brassiere including the X-shaped support 51. The X-shaped support 51 includes the upper right fork 54, the lower right fork 55, the upper left fork 56 and the lower left fork 57. Furthermore a bride portion 62 is provided between the right and left cups 60, 61 and each of the right and left cups 60, 61 includes a lower area 63, a side area 64, an upper area 65 and a shoulder strap attachment area 66. FIG. 6 depicts the positioning of the X-shaped support 51, in which the lower right fork 55 extends from the bridge portion 62, along the lower area 63 of the right cup 60 and terminates at a lower portion 63a of the lower area 63 of the right cup 60 that is before the side area 64, and in which the lower left fork 57 extends from the bridge portion 62, along the lower area 63 of the left cup 61 and terminates at a lower portion 63a of the lower area 63 of the left cup 61 that is before the side area 64. Each of the upper right and left forks 54, 56 extend from the bridge portion 62 and along an inside portion of the upper area 65 of the right and left cups 60, 61, respectively. FIG. 8 illustrates the brassiere with X shaped support 51 of the present invention fitted on simulated models, as well as a right shoulder strap 70 and a left shoulder strap 71 attached at the shoulder strap attachment area 66 of each cup. It is understood that the steps described above are not necessarily performed in the order as described and variations of the order are possible which can be made by a person of ordinary skill in the art.

(17) Optionally, an extra filling, such as, for example, polyurethane foam, fiberfill, oil sac, gel sac, air sac or silicone sac, which may be formed into a shape shown in FIG. 7, can be sandwiched between outer and inner cup panels during the molding process (of course, with proper selection of the male and female of the mold so as to provide necessary room for the extra filling.

(18) While there have been described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes, in the form and details of the embodiments illustrated, may be made by those skilled in the art without departing from the spirit of the invention. The invention is not limited by the embodiments described above which are presented as examples only but can be modified in various ways within the scope of protection defined by the appended patent claims.
