Description

Technical Field

[0001] The invention belongs to the field of bras, and in particular relates to a bra with breathable and warm-keeping functions. Background Art

[0002] With the continuous advancement of social technology and the progress of human civilization, people's demands for a higher quality of life are growing. They are placing increasing demands on product functionality, chemical-free properties, and environmental friendliness, as well as increasing attention to the impact of products on their health. Bras are essential for women, but the supporting material used in most bras is chemically foamed sponge, which is detrimental to breast health. The sponge also has poor breathability, hindering breast dryness and absorbing sweat, especially during exercise, leading to stuffiness. Furthermore, the sponge's poor elasticity and poor rebound after compression make it difficult to support the breasts. Bras are particularly crucial during exercise.

[0003] The functionality of a bra not only impacts the wearer's exercise performance but also their health. For example, a bra that's too loose won't provide adequate vibration control during exercise. A bra that's too tight, while effective at preventing vibration, can easily lead to shortness of breath. Prolonged confinement also affects the bra's breathability, hindering the release of sweat and heat, leading to discomfort. Furthermore, existing bras often focus on breathability, whereas the human body sweats profusely during exercise and requires a certain degree of warmth after exercise.

[0004] To address these issues, those skilled in the art have conducted in-depth research on bras, developing patented technologies such as the perspiration-wicking, breathable bra (Patent 202223227176.X). These technologies incorporate ventilation holes in the bra cups and chest straps, attempting to achieve a certain degree of perspiration and ventilation. However, because sports bras fit tightly against the human body, the ventilation holes become blocked by the body, preventing air convection and impacting the intended technical benefits. Furthermore, there has been no in-depth research into the warmth-retaining properties of bras.

[0005] In order to solve the above-mentioned problems, the purpose of the present invention is to provide a bra that can maintain a breathable effect during exercise and can also achieve heat storage and cold protection functions after exercise. Summary of the Invention

[0006] In order to achieve the above functions, the technical solution adopted by the present invention is: A breathable and warm-keeping bra is provided with a breathable and warm-keeping component filled with supercritical foaming particles on the bra body.

[0007] The breathable and warming component is arranged on the shoulder straps, lower part and cup pieces of the bra body; or is set on the front piece of the lower part of the bra; and / or the breathable and warming component is arranged under the bra cup piece; and / or the breathable and warming component is arranged under the bra cup piece and extends to the side.

[0008] The breathable and heat-insulating component comprises a cavity and supercritical foaming particles filled in the cavity; the supercritical foaming particles are evenly or intermittently distributed in the cavity.

[0009] The breathable and warm-keeping component is arranged on the upper surface and the lower surface of the bra body, and / or the breathable and warm-keeping component is a part of the bra body.

[0010] There are two different schemes for forming the cavity: First, the cavity is formed by combining two layers of fabric, upper and lower; or, the cavity is formed by folding a single layer of fabric back and forth.

[0011] The cavity is a single chamber, or the cavity is composed of several chambers; the inner cavity height and / or width of the chamber is 4-10 mm.

[0012] Secondly, the cavity is made of an integral woven material; the integral woven material comprises an upper surface, a lower surface, and a plurality of pull lines connected between the upper surface and the lower surface; the pull lines form the cavity into a plurality of chambers interconnected with each other.

[0013] The pull wire height is 3-10 mm.

[0014] Pull lines of different heights are arranged at different parts of the bra.

[0015] The beneficial effects of the present invention are: A breathable and warm bra is provided, which has a breathable and warm component made of supercritical foam particles, replacing conventional sponge materials through supercritical foaming. 1. Due to the gaps between the supercritical foam particles, air circulation is maintained between the inside and outside of the bra, accelerating the volatilization of sweat and heat during exercise, thereby achieving a breathable and dry effect. 2. The supercritical foam particles themselves have excellent shock absorption and rebound properties. During exercise, the bubble structure deforms in response to the vibration generated by the movement, absorbing the vibration force during exercise, thereby reducing the vibration effect, saving exercise energy to a certain extent, and improving athletic performance. 3. The supercritical foam particles have a closed bubble structure. When worn next to the skin, the bubble structure maintains a certain distance between the human skin surface and the outside world, cutting off the transfer path between the human body heat and the outside world, retaining the human body heat inside the bra, thereby achieving a heat storage and cold protection effect. 4. The production process of the supercritical foam material does not use chemical foaming agents, making the material more environmentally friendly and beneficial to protecting human health.

[0016] The cavity holds the supercritical foam particles in relative positions, effectively controlling their distribution and achieving breathability, warmth, and vibration reduction based on the needs of different body parts. Furthermore, the supercritical foam particles move freely within the cavity, autonomously adjusting their thickness distribution based on body shape and pressure, achieving a body-adaptive effect.

[0026] The present invention is further described below with reference to the accompanying drawings.

[0027] Description of reference numerals: 1——Bra body 2——Shoulder straps 3——Underparts 4——cup piece 41——Below the cup 42——Side of cup 5——Breathable and warm components 51——Vacuum 511——Upper surface of the cavity 512——Lower surface of the cavity 513——Partition tape 52——Supercritical foaming particles 53——One-piece fabric 531 - Upper surface of fabric 532 - Fabric lower surface 533——Pull Wire Example 1

[0028] like Figure 1 As shown in FIG. 1 , the conventional brassiere of the present invention is breathable and warm, comprising a bra 1, shoulder straps 2, a lower band 3, and a cup piece 4. The brassiere shoulder straps 2 and the cup piece 4 are both provided with a breathable and warm component 5. Figure 2 As shown, the breathable and warm sports bra of the present invention comprises a bra 1, shoulder straps 2, a lower band 3, a cup piece 4, a lower portion 41 of the cup piece, and a side portion 42 of the cup piece. The shoulder straps 2, the lower band 3, the lower portion 41 of the cup piece, and the side portion 42 of the cup piece are all provided with a breathable and warm component 5. Figure 3 As shown, the breathable and thermal insulation component 5 is provided with a cavity 51 and supercritical foam particles 52 filled in the cavity 51. The cavity 51 is formed by combining the cavity upper surface 511 and the cavity lower surface 512 through a sewing process or a hot pressing bonding process. During the preparation process, the fabric of the cavity upper surface 511 is extended and folded downward, or the cavity lower surface 512 is extended and folded upward to form a cavity partition belt 53. The cavity upper surface, the cavity lower surface and the partition belt are connected to form a cavity 51 for filling the supercritical foam particles 52. Figure 4 As shown, the cavity 51 is formed by combining two layers of fabric, or a single layer of fabric folded back and forth. Supercritical foam particles 52 are filled within the cavity and can be moved within the cavity under force before being integrated with the bra body. The cavity 51 can be integrated with the bra body in various ways: the cavity filled with supercritical foam particles 52 is placed on the upper or lower surface of the bra body, and / or the breathable and thermal insulation component is integral to the bra body.

[0029] Supercritical foam particles 52 are used to replace the sponge material of the prior art. When worn, there is a certain gap between different supercritical foam particles 52. During exercise, gas convection is maintained inside and outside the bra, and sweat and heat from the human skin are quickly dissipated to the outside world, keeping the skin dry. At the same time, the supercritical foam particles 52 themselves have good shock absorption and rebound functions. During exercise, the bubble structure deforms due to the vibration generated by the exercise, absorbing the vibration force during the exercise, achieving the effect of reducing the vibration, saving exercise energy to a certain extent, and improving exercise performance. In addition, a breathable and warm component 5 is provided on the shoulder strap 2. Not only does it keep the skin in contact with the shoulder strap breathable, but the supercritical foam particles 52 in the breathable and warm component 5 move the position of the supercritical foam particles according to the user's shoulder shape, realizing the adaptive function of the shoulder strap and preventing the shoulder strap from sliding outward.

[0030] Currently, bras are manufactured based on human body size standards in terms of size and structure. However, the body shape of each person is different, resulting in uneven tightness of the bras during wear, which cannot meet the body shape characteristics of all consumers. The bra of the present invention sets the cavity height below the cup piece 41 and the side of the cup piece 42 to 10mm. After filling with supercritical foam particles 52, supercritical foam particles of different sizes and shapes can move freely inside the cavity. The thickness distribution of the foam particles can be adjusted independently according to different body shapes and pressures, achieving the effect of adaptive body shape. The cavity height of the shoulder straps 2 and the lower band 3 is set to 4mm. After filling with supercritical foam particles, the supercritical foam particles are evenly spread inside the cavity. The single layer of supercritical foam particles absorbs the force of muscle tremors during exercise, improving athletic performance.

[0031] Meanwhile, existing bras filled with sponge are often compacted by the body-shaping function during repeated washing or wearing, making the bras less breathable and causing heat to evaporate quickly after exercise, affecting their warmth retention. The supercritical foam particles used in the bras of this embodiment have a closed bubble structure. When worn next to the skin, the bubble structure creates a certain separation between the skin surface and the outside world, cutting off the heat transfer path between the body and the outside world and retaining the body heat inside the bra, thereby achieving the effect of heat storage and cold protection, protecting human health. Example 2

[0032] like Figure 5As shown, based on the structure of Example 1, the bra cavity for this breathable and warming bra is constructed from a single piece of fabric 53. This single piece of fabric 53 comprises an upper surface 531, a lower surface 532, and several drawstrings 533 connecting the upper and lower surfaces. The drawstrings 533 form a series of interconnected chambers. The drawstrings 533 are 10 mm high below the bra cups 41 and to the sides 42. These are filled with supercritical foam particles instead of sponge, ensuring excellent ventilation. The drawstrings 533 are 3 mm high at the shoulder straps 2 and underband 3. After filling, the supercritical foam particles are evenly distributed within the cavity. Because the drawstrings 533 are connected to the upper and lower surfaces in a point-like manner, the fullness of the supercritical foam particles can be adjusted as needed. After filling, the cavity height remains between 3 and 5 mm, depending on the fill level. Furthermore, the supercritical foam particles absorb the force of muscle vibration during exercise, enhancing athletic performance. Example 3

[0033] Based on the principles and structures of the first and second embodiments, Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the breathable and warm bra components of the present invention can be independently installed on the shoulder straps, underband, cups, or underneath the bra cups. The breathable and warm components can be flexibly integrated into the bra. They can be placed inside the bra itself, directly contacting the skin to achieve ventilation while blocking the path for heat dissipation and retaining warmth. They can also be placed outside the bra itself, contacting outer clothing to retain heat within the garment. Alternatively, they can be integrated into the bra itself, integrating with other bra components through sewing or laminating.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it should be understood by those skilled in the art that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
