Brassiere

The present application claims priority to Chinese Patent Application No. 202521483248.8, filed on Jul. 15, 2025, the entire contents of which are incorporated herein by reference.

The present application relates to the technical field of maternal and baby products, particularly to a brassiere.

Brassieres, as intimate apparel, typically require a balanced design between functionality, comfort, and aesthetics in their construction. Edge design constitutes a crucial aspect of brassiere design that directly affects both wearing comfort and visual appearance.

In existing technologies, brassiere edge treatment commonly adopts a double-layer fabric adhesive bonding method, where the inner and outer fabric layers are bonded together using adhesive to achieve smooth and neat edges. This process partially addresses issues present in traditional stitching techniques, such as excessive edge thickness and noticeable protrusions, while simultaneously avoiding direct friction between sewing threads and the skin. However, this double-layer fabric adhesive bonding process also exhibits several significant shortcomings.

First, although the double-layer fabric adhesive bonding process in existing technologies can make brassiere edges smooth, the complete alignment of the inner and outer fabric edges prevents further optimization of edge thickness. Even with relatively thin adhesive layers, the combined thickness of the inner and outer fabric layers with the adhesive layer still forms a certain edge thickness, which may create pressure on the skin during wear. This is particularly evident in areas where the brassiere contacts the skin (such as shoulder strap areas or cup edges), and prolonged wear may cause discomfort.

Second, when the edges of the inner and outer fabric layers are completely aligned, the edge's softness and elasticity are relatively poor, which may result in inadequate fit during wear. Especially in scenarios involving more body movement, the edges are prone to lifting due to pressure or tension, affecting the brassiere's skin-contact effect. This not only reduces wearing comfort but may also make edge marks visible through outerwear, compromising aesthetics. Additionally, the double-layer fabric adhesive bonding process may reduce the brassiere's service life due to uneven adhesive distribution or aging, with edges being prone to adhesive failure or deformation after multiple washes.

Therefore, although the existing double-layer fabric adhesive bonding technology represents an improvement over traditional stitching processes, there remains room for optimization in terms of edge thickness, skin-contact effect, and durability. Particularly against the backdrop of increasing consumer demands for lighter, more invisible, and comfortable brassieres, how to further reduce brassiere edge thickness, improve skin-contact effect, and ensure edge softness and durability has become an urgent technical problem to be solved in the field of brassiere design.

In view of the deficiencies in the prior art, embodiments of the present application provide a brassiere that can solve the problems of poor edge fit in existing brassieres, which result in reduced comfort and aesthetics.

In the embodiments of the present application, the brassiere may include: an inner layer, an outer layer, and cups.

As shown in, in this embodiment, the outer layeris stacked with the inner layer, and at least a portion of the outer layeris bonded to the inner layervia adhesive. Compared to the outer layer, the inner layeris positioned closer to the wearer's skin during use, while the outer layeris positioned farther from the wearer's skin compared to the inner layer.

The inner layerand outer layermay be fabric materials. The inner layermay employ skin-friendly anti-slip fabric and may include ventilation holes. The inner layermay use a nylon-spandex blended fabric, for example, a blend of 57% nylon and 43% spandex, with the inner layeremphasizing skin comfort while maintaining structural stability through the nylon majority. The outer layermay use high-elasticity fabric, which could also be a nylon-spandex blend, such as 61% nylon and 39% spandex. The outer layerfeatures high elasticity, with the spandex providing ≥30% stretch rate, and high abrasion resistance, with the nylon having a strength ≥4.5 cN/dtex, making it suitable for the molded outer side of the cups. In other implementations, the inner layerand outer layermay use alternative fabrics, which are not limited in the embodiments of this application.

As shown in, at least partial regions of the inner layerand outer layerare bonded together through adhesive, where in some embodiments the inner layermay be formed by adhesively joining several different fabric pieces and similarly the outer layermay also be formed by adhesively joining multiple fabric pieces, or alternatively both the inner layerand outer layermay each consist of a single continuous piece of fabric, with the inner layerand outer layerbeing bonded together in the peripheral regions surrounding the cupsto form an integrated structure that creates two accommodation spaces between the unbonded areas of the inner and outer layers to respectively contain the two cups corresponding to the wearer's left and right breasts, while in some embodiments these two accommodation spaces may be interconnected with the two cups being positioned at different locations within the same continuous accommodation space.

The outer layerand inner layermay be bonded using hot melt adhesive through laser cutting and heat pressing technology to achieve seamless bonding effects for the brassiere.

The adhesivemay be selected from hot-melt pressure-sensitive adhesive, water-based eco-friendly adhesive, reactive polyurethane hot-melt adhesive, acrylic adhesive, or polyurethane adhesive, all of which demonstrate excellent bonding performance and environmental properties to meet various application requirements, wherein the hot-melt pressure-sensitive adhesive provides rapid curing and strong initial adhesion suitable for applications requiring fast bonding with high initial adhesion demands, while the water-based eco-friendly adhesive is characterized by environmental friendliness, non-toxicity and odorlessness better meeting modern health-conscious lifestyles, and the reactive polyurethane hot-melt adhesive combines polyurethane's superior elasticity with hot-melt adhesive's rapid-curing properties to achieve excellent bonding while maintaining garment softness and comfort, with acrylic adhesive offering good weather resistance and water resistance making it suitable for outdoor or humid environments and polyurethane adhesive featuring high strength and abrasion resistance being more appropriate for garment areas subjected to significant tension or wear, whereby selecting the appropriate adhesive type can further enhance garment quality and durability to satisfy diverse consumer needs.

As shown in, at least a portion of the edge of the outer layerextends beyond the corresponding edge of the inner layeror at least a portion of the edge of the inner layerextends beyond the corresponding edge of the outer layer, such that the inner layerand the outer layerare misaligned at least along portions of their edges. This staggered edge configuration between the inner layerand outer layer, where the edges are deliberately misaligned, results in the brassiere's edge consisting of only a single layer (either the inner layer or outer layer), thereby creating a thinner edge profile that enhances skin contact during wear and significantly improves wearing comfort.

As shown in, in the present embodiment, at least a portion of the edge of the outer layerextends beyond the corresponding edge of the inner layer. This configuration prevents visible traces on the outer surface of the brassiere while achieving both the thin-edge skin-contact effect and maintaining aesthetic appearance.

As shown in, in one embodiment, the at least a portion of the edge of the outer layercomprises the brassiere's outer lower edge, outer neckline edge, or outer underarm edge. In one embodiment, the at least a portion of the edge of the inner layercomprises the brassiere's inner lower edge, inner neckline edge, or inner underarm edge.

As shown in, in one embodiment, the outer lower edgeof the outer layerextends beyond the inner lower edgeof the inner layer, thereby creating misalignment between the inner layerand outer layerat the brassiere's lower edge position.

In one embodiment, the outer neckline edgeof the outer layerextends beyond the inner neckline edgeof the inner layer, thereby creating misalignment between the inner layerand outer layerat the brassiere's neckline edge position.

In one embodiment, the outer underarm edgeof the outer layerextends beyond the inner underarm edgeof the inner layer, thereby creating misalignment between the inner layerand outer layerat the brassiere's underarm edge position.

In other embodiments, at least a portion of the edge of the inner layer extends beyond the corresponding edge of the outer layer, although such embodiments are not shown in the figures. For example, in one embodiment, the inner lower edgeof the inner layerextends beyond the outer lower edgeof the outer layer, creating misalignment between the inner layerand outer layerat the brassiere's lower edge position. As another example, in one embodiment, the inner neckline edgeof the inner layerextends beyond the outer neckline edgeof the outer layer, creating misalignment at the brassiere's neckline edge position. As a further example, in one embodiment, the inner underarm edgeof the inner layerextends beyond the outer underarm edgeof the outer layer, creating misalignment at the brassiere's underarm edge position.

This approach enables design optimization tailored to the specific requirements of different brassiere sections. For instance, extension of the outer lower edge can effectively reduce discomfort caused by friction during wear while enhancing overall aesthetics; whereas extension of the inner neckline edge ensures proper fit while preventing excessive skin pressure, thereby improving comfort. Additionally, optimization of the underarm edge design through staggered alignment can reduce localized bulk, making the brassiere more lightweight and flexible during physical activities or daily wear. By implementing such differentiated treatments for specific edges, the design can better satisfy consumers' dual demands for both functionality and comfort, while simultaneously providing greater design flexibility and innovation potential for brassiere construction.

As shown in, the cupis disposed between the inner layerand outer layerwhere the cupmay be positioned within the accommodation space formed after bonding the inner layerand outer layer, with the cupbeing a molded foam pad made of polyester fiber while in some embodiments the cupmay also be formed by composite molding of multiple material layers with its shape substantially conforming to the wearer's breast contour, and where the cupmay alternatively utilize memory foam or gel pads with portions of the cupbeing adhesively bonded to the brassiere's inner layervia adhesivewhile in other embodiments the cupmay be fixed by stitching which is not limited in these embodiments and where in further embodiments the cupmay be secured to the brassiere's outer layerthrough adhesive bonding which is similarly not limited in these embodiments, with the cupbeing capable of fixation to the brassiere's outer or inner layers at multiple positions without limitation in these embodiments.
