The present application claims priority to Chinese Patent Application No. 202521099007.3, filed on May 29, 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.

As an intimate apparel product, brassieres typically require insertion of molded cups into designated positions during manufacturing to achieve optimal fit and support functions. In modern brassiere production processes, an opening is conventionally incorporated into the design to facilitate installation of the molded cups. The molded cups are inserted through this opening to complete assembly, a technique widely employed in industrial brassiere manufacturing.

However, conventional designs of cup insertion openings exhibit several technical deficiencies. Particularly after prolonged use or repeated washing, the opening edges are prone to tearing or deformation due to external forces such as stretching and friction. The insufficient structural strength of these opening edges may lead to damage during cup insertion, significantly compromising the durability of the opening section. Furthermore, inadequate elasticity along the opening edges may result in suboptimal installation smoothness for the molded cups, while simultaneously adversely affecting the overall structural stability and wearing comfort of the brassiere.

In view of the deficiencies in prior art, the present application provides a brassiere capable of resolving issues of short service life and susceptibility to damage at the cup insertion opening.

To address the aforementioned technical problems, one technical solution adopted in embodiments of this application is to provide a brassiere comprising: a housing forming an accommodation space therein, the housing having an opening communicating between interior and exterior of the accommodation space; a molded cup disposed within the accommodation space; and an elastic adhesive film and a reinforcement strip bonded via the elastic adhesive film to a peripheral region of the opening.

In the embodiments of the present application, the brassiere may comprise shoulder straps, a housing, molded cups, an elastic adhesive film, and a reinforcement strip.

As shown in, in one embodiment, the number of shoulder strapsis two, both connected to the housing. The primary functions of brassiere shoulder straps are to provide support and stability, ensuring better body conformity while helping distribute breast weight to reduce pressure on the back and shoulders. In some embodiments, the brassiere may exclude shoulder straps, such as in strapless brassiere designs.

The housingforms an accommodation space therein and is provided with an openingthat communicates between the interior and exterior of the accommodation space. The openingserves to allow insertion of the molded cupinto the accommodation space. In some embodiments, the housing may be made of fabric materials, specifically including but not limited to nylon, spandex, polyester, Lycra fabric, cotton blends, etc.

The molded cupsare disposed within the accommodation space. The number of molded cupsmay be two, corresponding to two accommodation spaces respectively designed to accommodate each molded cup. The primary functions of the brassiere's molded cupsinclude providing breast support, shaping and protection, while enhancing wearing comfort and aesthetic appearance. The molded cupsmay be composed of one or more materials selected from polyurethane foam, polyester fiber, and non-woven fabric.

As shown in, the reinforcement stripis bonded via the elastic adhesive filmto a peripheral region of the opening.

The elastic adhesive filmis formed by curing adhesive materials, which may include hot-melt pressure-sensitive adhesive, water-based environmentally friendly adhesive, reactive polyurethane hot-melt adhesive, acrylic adhesive, or polyurethane adhesive. These adhesive types all exhibit excellent bonding performance and environmental characteristics, meeting various application requirements. The hot-melt pressure-sensitive adhesive features rapid curing and strong initial tack, making it suitable for applications requiring quick bonding with high initial adhesion demands. The water-based environmentally friendly adhesive is renowned for being eco-friendly, non-toxic, and odorless, better aligning with modern health-conscious lifestyles. The reactive polyurethane hot-melt adhesive combines the superior elasticity of polyurethane with the rapid curing properties of hot-melt adhesives, providing effective bonding while maintaining garment softness and comfort. Acrylic and polyurethane adhesives each have distinct characteristics-acrylic adhesive demonstrates excellent weather resistance and water resistance, making it suitable for outdoor or humid environments, while polyurethane adhesive offers high strength and wear resistance, making it more appropriate for garment areas subject to significant tension or abrasion. Selecting the appropriate adhesive type can further enhance garment quality and durability to meet diverse consumer needs.

In one embodiment, the reinforcement stripis continuously arranged along the circumferential direction of the openingedge. In this embodiment, the reinforcement stripforms a complete loop around the opening. It should be understood that in other embodiments, the reinforcement stripmay be disposed only at partial locations along the openingedge, not necessarily forming a closed loop, which is not limited in the embodiments of this application. When the reinforcement stripis continuously arranged along the openingedge, it can effectively distribute stress acting on the opening edge, preventing deformation, tearing, or damage caused by external forces, thereby improving overall structural strength and durability. Strategically placing the reinforcement stripat key locations allows for targeted reinforcement based on stress requirements, enhancing critical areas while avoiding material waste. The loop-shaped reinforcement stripprovides uniform support to the openingedge, preventing damage during insertion of the molded cupthrough the opening, while reducing edge warping or unevenness. In some embodiments, the width of reinforcement stripranges approximately between 2 mm-8 mm, such as 2 mm, 6 mm, or 8 mm.

As shown in, in one embodiment, the housingcomprises an inner layerand an outer layerarranged in superposition. The inner layerand outer layerremain unbonded in the region corresponding to the accommodation space, while being at least partially bonded together in overlapping regions outside the accommodation space to form the accommodation space between the inner layerand outer layer.

This structural design provides the accommodation space with excellent stability and independence. The inner layerdirectly contacts components placed within the accommodation space such as the molded cup, offering a soft touch surface that prevents scratching of the molded cup. The outer layerserves protective and reinforcing functions, enhancing the overall strength of the housing. By partially bonding the inner layerand outer layerin overlapping regions outside the accommodation space, this configuration maintains the accommodation space while forming a relatively stable integrated structure, preventing separation or misalignment between the inner layerand outer layer. Consequently, this ensures reliable brassiere structural integrity and provides users with improved wearing comfort.

In one embodiment, the openingis disposed on the inner layer. The inner layeris positioned closer to the wearer's body when the brassiere is worn, while the outer layeris positioned farther from the wearer's body.

This configuration allows components such as the molded cupto be conveniently inserted into or removed from the accommodation space from the side closer to the body, facilitating easier operation. Since the inner layeris adjacent to the wearer's body, locating the openinghere prevents interference with outer garments during installation or adjustment of the molded cup, thereby improving usability. Moreover, when the brassiere is worn, the openingremains concealed against the skin, maintaining the brassiere's external appearance integrity and aesthetic appeal while optimizing wearer comfort.

In one embodiment, the reinforcement stripis bonded via the elastic adhesive filmto a surface of the inner layerfacing the outer layer. This means the reinforcement stripis positioned within the accommodation space between the inner layerand outer layer, making it invisible from the exterior of the brassiere. This design preserves the garment's aesthetic continuity while preventing any potential friction between the reinforcement stripand the wearer's skin during use.

In one embodiment, the molded cupis fixed to the housingat fixation regions including an upper fixation regionand a lower fixation region. When worn, the upper fixation regionis positioned above the wearer's nipple while the lower fixation regionis positioned below the nipple.

This dual fixation configuration provides precise breast support: the upper fixation regioneffectively lifts the breast to create optimal shaping and prevent gravitational sagging, while the lower fixation regionbears the primary support load to evenly distribute breast weight and reduce pressure. This design offers stable support during movement, significantly enhancing wearing comfort and functionality. Furthermore, the strategic placement of these fixation regions accommodates various breast shapes by providing customized support points along the body's natural contours, improving the brassiere's adaptability to different body types and meeting diverse consumer needs.

In one embodiment, the molded cupis adhesively fixed to the housingat the fixation regions. Specifically, the molded cupis bonded to the housingat both the upper fixation regionand lower fixation regionthrough adhesive bonding.

This adhesive fixation method offers simple and convenient operation while ensuring stable connection between the molded cup and housing. During production, it effectively improves manufacturing efficiency and reduces production costs. Additionally, adhesive fixation creates a smoother overall appearance for the brassiere by eliminating potential protrusions or gaps that may occur with alternative fixation methods, thereby enhancing both wearing comfort and aesthetic appeal. Furthermore, proper adhesive selection ensures the fixation integrity between the molded cup and housing remains unaffected through extended wear and washing cycles, prolonging the brassiere's service life.

In one embodiment, the upper fixation regionhas an extension length shorter than that of the lower fixation region.

This design provides stronger support in the lower portion where most breast weight is concentrated. The extended lower fixation region better distributes and bears this weight, preventing breast sagging due to insufficient support. Simultaneously, the shorter upper fixation region avoids excessive constriction on the upper breast area, maintaining natural breast shape and breathing space for greater freedom of movement and comfort, further optimizing the wearing experience for different breast types.
