Description

Technical Field

[0001] The present invention relates to the field of underwear, and in particular to a breathable cup and underwear. Background Art

[0002] As the main part of the bra, the cup is in direct contact with the chest. In addition to supporting and gathering the chest, it also plays a role in highlighting the beauty of women. However, when the bra is worn, there are other clothes on the outside of the bra. Therefore, the chest area is usually stuffy and humid. Especially in hot seasons or after exercise, the poor air permeability of the bra will cause discomfort to the user and is not conducive to the health of the chest.

[0003] CN107927922A discloses a breathable mold cup. The breathable mold cup includes a sponge middle layer, an inner layer covering the inner surface of the sponge middle layer, and an outer layer covering the outer surface of the sponge middle layer. The sponge middle layer is pressed from high-elastic cotton or foamed cotton, and the inner layer and the outer layer are both made of hygroscopic yarn. The sponge middle layer is punched and formed with a plurality of air holes, and the plurality of air holes are evenly distributed. The breathable mold cup provided by the present invention has good air permeability. It is opened from the inside to the outside to keep dry and breathable, prevent the breasts from being stuffy and humid, and provide a healthy and comfortable environment for the breasts. Although the air permeability is improved, the support of the mold cup to the chest is affected only by the sponge middle layer with air holes, and the degree of improvement in air permeability is limited. Summary of the invention

[0004] In view of this, the present invention aims to provide a breathable cup and underwear to solve the problem in the prior art that underwear cannot have both good breathability and support.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] On the one hand, a breathable cup includes a breathable inner layer, a breathable middle layer and a breathable outer layer connected in sequence, the breathable inner layer covers the chest, the breathable inner layer includes a first material position and a first material vacant position, the breathable outer layer includes a third material position and a third material vacant position, the breathable middle layer includes a second material position and a second material vacant position, and on any cross section of the breathable middle layer, the occupied area of ​​the second material position is S61, and the occupied area of ​​the second material vacant position is S62, and the S61 and S62 satisfy S6=S62 / (S61+S62), 0.8≤S6<1. The breathable inner layer, breathable middle layer and breathable outer layer of the present invention are materials with vacant positions, which are conducive to the circulation of air. Without changing the shape, function and production process of the cup, the breathability of the cup is improved by using the structure of the material itself, and because no additional through holes are provided on the inner and outer layers, the cup product has a smooth appearance and good visual effect. By limiting the S6 of the breathable middle layer, air can easily pass through the breathable middle layer, accelerating the air flow around the chest to take away heat, thereby achieving the ventilation function. The three-layer structure makes up for the adverse effects of the vacant position on the strength and support of the cup, which is conducive to ensuring the strength of the cup body and providing good support and shaping for the chest.

[0007] Furthermore, on any cross section of the breathable inner layer, the occupied area of ​​the first material position is S41, the occupied area of ​​the first material vacant position is S42, and S41 and S42 satisfy S4=S42 / (S41+S42), 0.5≤S4<1; on any cross section of the breathable outer layer, the occupied area of ​​the third material position is S51, the occupied area of ​​the third material vacant position is S52, and S51 and S52 satisfy S5=S52 / (S51+S52), 0.5≤S5<1, S6>S4 and S6>S5. The vacancy ratio of the breathable middle layer is greater than the vacancy ratio of the inner and outer layers, and the degree of air passing through the breathable middle layer is easy for air to pass through the breathable inner layer and the breathable outer layer, avoiding the poor air circulation caused by the breathable middle layer being affected by the inner and outer sides due to being in the middle position. At the same time, by limiting the specific values ​​of S4, S5 and S6, the relationship between the vacant positions and the support of the cup is balanced. On the premise that there are enough vacant positions and the air can flow smoothly in the cup, the supporting strength of the cup can be guaranteed, the chest can be better supported, and the comfort of use can be improved.

[0008] Furthermore, a first surface layer is arranged on the inner side of the breathable inner layer, and a second surface layer is arranged on the outer side of the breathable outer layer. The breathable inner layer and the breathable outer layer form an air circulation channel, and the first surface layer and the second surface layer can absorb moisture and perspiration in time. The multi-layer structure works synergistically to keep the contact between the cup and the chest dry, prevent the chest from being stuffy and humid, and improve the wearing comfort of the user.

[0009] Furthermore, the first surface layer is in direct contact with the breathable inner layer or bonded with an adhesive, and the second surface layer is in direct contact with the breathable outer layer or bonded with an adhesive.

[0010] Furthermore, the first surface layer and the breathable inner layer are bonded and connected, and the connection between the two is the first adhesive cross section. The second surface layer and the breathable outer layer are bonded and connected, and the connection between the two is the second adhesive cross section. The ratio of the area of ​​the first adhesive cross section after bonding to the actual occupied area of ​​the first material vacant position before bonding in any cross section is A, 50%<A≤80%, and the ratio of the area of ​​the second adhesive cross section after bonding to the actual occupied area of ​​the third material vacant position 52 in any cross section before bonding is B, 50%<B≤80%. By limiting the values ​​of A and B, it is avoided that the adhesive used for bonding affects the air permeability of the material vacant position, and at the same time, the bonding strength between the first surface layer 2 and the breathable inner layer 4, and the bonding strength between the second surface layer 3 and the breathable outer layer 5 can be guaranteed.

[0011] Furthermore, the thickness of the breathable inner layer at 10 mm above the center direction is 1-4 mm, the thickness of the breathable outer layer at 10 mm above the center direction is 1-4 mm, and the thickness of the breathable middle layer at 10 mm above the center direction is 6-35 mm. This is used to make the cup thickness near the chest area moderate, to avoid being too thick to affect the heat dissipation effect, and to avoid being too thin to affect the support effect on the chest.

[0012] Furthermore, the breathable middle layer can be provided with one or more layers, and the number of layers of the breathable middle layer can be designed according to the thickness requirements of the user.

[0013] Furthermore, the breathable middle layer is provided with through holes. The second material vacancy position is a vacancy in the breathable middle layer structure itself, and the through holes are structures added to the breathable middle layer by further processing methods, for further improving the breathability.

[0014] Compared with the prior art, the breathable cup of the present invention has the following advantages:

[0015] (1) The breathable inner layer, breathable middle layer and breathable outer layer of the present invention are made of materials with vacant positions, which are conducive to the circulation of air. Without changing the appearance, function and production process of the cup, the breathability of the cup is improved by utilizing the structure of the material itself. In addition, since no additional through holes are provided on the inner and outer layers, the appearance of the cup product is smooth and the visual effect is good.

[0016] (2) By limiting the S6 of the breathable middle layer, air can easily pass through the breathable middle layer, accelerating the air flow around the chest to take away heat, thereby achieving the ventilation function. The three-layer structure compensates for the adverse effects of the vacant position on the strength and support of the cup, which is conducive to ensuring the strength of the cup body and providing good support and shaping for the chest.

[0017] (3) The vacancy ratio of the breathable middle layer is greater than that of the inner and outer layers. The degree to which air passes through the breathable middle layer is easy for air to pass through the breathable inner layer and the breathable outer layer, avoiding the breathable middle layer being affected by the inner and outer sides and causing poor air circulation. At the same time, by limiting the specific values ​​of S4, S5 and S6, the relationship between the vacancy position and the cup support is balanced. Under the premise of sufficient vacancy positions to ensure smooth air flow in the cup, the support strength of the cup can also be guaranteed, the chest can be better supported, and the comfort of use can be improved.

[0018] Another aspect of the present invention provides an undergarment comprising the above-mentioned breathable cup. The advantages of the undergarment and the above-mentioned breathable cup over the prior art are the same, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In addition, the directions involved in the following specific embodiments are briefly described: the directions or positional relationships indicated by "front", "rear", "upper", "lower", "left", "right", "top", "bottom" and the like mentioned in the embodiments refer to the directions or positional relationships shown in the accompanying drawings, and the term "on..." refers to being directly or indirectly supported by... elements.

[0027] It should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figures 1 to 3 As shown, a breathable cup 1 of the present invention comprises a breathable inner layer 4, a breathable middle layer 6 and a breathable outer layer 5 connected in sequence, the breathable inner layer 4 covers the chest, the breathable inner layer 4 comprises a first material position 41 and a first material vacant position 42, the breathable outer layer 5 comprises a third material position 51 and a third material vacant position 52, the breathable middle layer 6 comprises a second material position 61 and a second material vacant position 62, on any cross section of the breathable middle layer 6, the occupied area of ​​the second material position 61 is S61, the occupied area of ​​the second material vacant position 62 is S62, and S61 and S62 satisfy S6=S62 / (S61+S62), 0.8≤S6<1.

[0029] The breathable inner layer 4, breathable middle layer 6 and breathable outer layer 5 of the present invention are materials with vacant positions, which are conducive to the circulation of air. Without changing the appearance, function and production process of the cup 1, the breathability of the cup 1 is improved by utilizing the structure of the material itself. Moreover, since no additional through hole 63 is provided on the inner and outer layers, the appearance of the cup 1 product is smooth and the visual effect is good. By limiting S6 of the breathable middle layer 6, air can easily pass through the breathable middle layer 6, accelerating the flow of air around the chest to take away heat, thereby realizing the breathable function. The setting of the three-layer structure makes up for the adverse effects of the vacant positions on the strength and support of the cup 1, which is conducive to ensuring the strength of the cup 1 body and providing good support and shaping for the chest.

[0030] As a preferred example of the present invention, the breathable inner layer 4, the breathable middle layer 6 and the breathable outer layer 5 are sponge materials or fiber materials suitable for the hot pressing and shaping process of the cup 1. The sponge or fiber itself has a vacant position and has good resilience, and can rebound quickly after the chest moves and squeezes the cup 1. After the cup 1 is squeezed by the chest, each layer is compressed and the air in the cup 1 is discharged. After the squeezing effect weakens or disappears, each layer partially recovers or fully recovers, and the air is inhaled at the same time. The cup 1 continuously switches between compression and recovery, so that the cup 1 has a breathing state. In this process, the flow of air around the chest can be greatly promoted, thereby realizing the ventilation function.

[0031] Further, on any cross section of the breathable inner layer 4, the occupied area of ​​the first material position 41 is S41, the occupied area of ​​the first material vacant position 42 is S42, and the S41 and S42 satisfy S4=S42 / (S41+S42), 0.5≤S4<1; on any cross section of the breathable outer layer 5, the occupied area of ​​the third material position 51 is S51, the occupied area of ​​the third material vacant position 52 is S52, and the S51 and S52 satisfy S5=S52 / (S51+S52), 0.5≤S5<1, S6>S4 and S6>S5. That is, the vacancy ratio of the breathable middle layer 6 is greater than the vacancy ratio of the inner and outer layers, and the degree of air passing through the breathable middle layer 6 is easy for air to pass through the breathable inner layer 4 and the breathable outer layer 5, avoiding the poor air circulation caused by the breathable middle layer 6 being affected by the inner and outer sides due to being in the middle position. At the same time, by limiting the specific values ​​of S4, S5 and S6, the relationship between the vacant positions and the support of the cup 1 is balanced. On the premise that there are enough vacant positions and the air can flow smoothly in the cup 1, the support strength of the cup 1 can be guaranteed, the chest can be better supported, and the comfort of use is improved.

[0032] In addition, due to the different vacancy ratios between the middle layer and the inner and outer layers, the vacancy ratio of the inner and outer layers is smaller, and there are more naturally elastic material positions, and the elasticity is also better than that of the middle breathable layer 6. The shaking of the chest produces a squeezing effect that causes the cup 1 to produce elastic deformation, and the layers of the cup 1 are compressed, and the air in the vacant positions of each layer is discharged. After the squeezing effect disappears, the cup 1 rebounds, and the breathable inner layer 4 and the breathable outer layer 5 will rebound first compared to the breathable middle layer 6. The air enters the breathable middle layer 6 through the breathable inner layer 4 and the breathable outer layer 5, that is, the air first enters from both sides of the cup 1. When the air reaches the breathable middle layer 6, the breathable middle layer 6 with a larger vacancy ratio rebounds, which is conducive to the entry of air into the breathable middle layer 6.

[0033] In the present invention, the thickness and shape of the breathable inner layer 4 and the breathable outer layer 5 are not specifically limited. The thickness and shape of the two can be the same or different, and S4 and S5 can be the same or different. The shape of the breathable inner layer 4 and the breathable outer layer 5 is preferably capable of wrapping the chest. The breathable middle layer 6 can be provided with one or more layers. The number of layers of the breathable middle layer 6 can be designed according to the thickness requirements of the user.

[0034] The first surface layer 2 is arranged on the inner side of the breathable inner layer 4, and the second surface layer 3 is arranged on the outer side of the breathable outer layer 5. The first surface layer 2 and the second surface layer 3 are breathable fabrics with good breathability and hygroscopicity. They are more skin-friendly when in direct contact with the skin, and can absorb sweat discharged from the chest in time to keep the chest dry. The breathable inner layer 4 and the breathable outer layer 5 form an air circulation channel, and the first surface layer 2 and the second surface layer 3 can absorb moisture and perspiration in time. The multi-layer structure works synergistically to keep the cup 1 and the chest dry, prevent the chest from being stuffy and humid, and improve the wearing comfort of the user.

[0035] The first surface layer 2 is in direct contact with the breathable inner layer 4 or bonded by an adhesive, and the second surface layer 3 is in direct contact with the breathable outer layer 5 or bonded by an adhesive. The breathable inner layer 4 and the breathable middle layer 6 can also be in direct contact without an adhesive layer in between, and the breathable outer layer 5 and the breathable middle layer 6 can also be in direct contact without an adhesive layer in between.

[0036] As a preferred example of the present invention, the first surface layer 2 and the breathable inner layer 4 are bonded and connected, and the connection between the two is the first adhesive section. The second surface layer 3 and the breathable outer layer 5 are bonded and connected, and the connection between the two is the second adhesive section. The ratio of the area of ​​the first adhesive section after bonding to the actual occupied area of ​​the first material vacant position 42 before bonding in any section is A, and 50%<A≤80%. The ratio of the area of ​​the second adhesive section after bonding to the actual occupied area of ​​the third material vacant position 52 before bonding in any section is B, and 50%<B≤80%. The bonding connection is usually achieved by gluing. The material vacancy position on the cross section before gluing is the largest. After the glue is attached to the breathable inner layer 4 and the breathable outer layer 5, the ratio of the material vacancy position before and after bonding will become smaller due to the increased adhesion of the glue. By limiting the values ​​of A and B, the adhesive is prevented from affecting the air permeability of the vacant positions of the material, while also ensuring the bonding strength between the first surface layer 2 and the breathable inner layer 4, and the bonding strength between the second surface layer 3 and the breathable outer layer 5.

[0037] The breathable inner layer 4 and the breathable middle layer 6 are bonded and connected, and the connection between the two is the third adhesive section. The breathable outer layer 5 and the breathable middle layer 6 are bonded and connected, and the connection between the two is the fourth adhesive section. The ratio of the area of ​​the third adhesive section after bonding to the actual occupied area of ​​the second material vacant position 62 before bonding at any section is C, and the ratio of the area of ​​the fourth adhesive section after bonding to the actual occupied area of ​​the second material vacant position 62 before bonding at any section is D. The said 50%<C≤85%, 50%<D≤85%. Specifically, the bonding connection is performed by dispensing, which is convenient for controlling the values ​​of A, B, C and D by setting the glue points during dispensing.

[0038] Furthermore, the thickness of the breathable inner layer 4 at a position 10 mm above the center is 1-4 mm, the thickness of the breathable outer layer 5 at a position 10 mm above the center is 1-4 mm, and the thickness of the breathable middle layer 6 at a position 10 mm above the center is 6-35 mm. This is used to make the cup 1 near the chest area have a moderate thickness, so as to avoid being too thick to affect the heat dissipation effect, and to avoid being too thin to affect the support effect on the chest.

[0039] As a preferred example of the present invention, Figure 4 As shown, the breathable middle layer 6 has a through hole 63. The second material vacancy position 62 is a vacancy in the structure of the breathable middle layer 6 itself, and the through hole 63 is a structure added to the breathable middle layer 6 by further processing, which is used to further improve the breathability. Since the added through hole 63 is located in the breathable middle layer 6, it is beneficial to cover the through hole 63 by the breathable inner layer 4 and the breathable outer layer 5, thereby improving the appearance flatness and overall aesthetics of the cup 1. The through hole 63 is obtained by one or more methods selected from mechanical processing, laser processing, and foaming molding.

[0040] The present invention also provides a bra, wherein the bra adopts the above-mentioned cup 1, and further comprises other common bra structures such as shoulder straps, a lower thong, and a back bra. Since these structures and related connection methods are prior art, they will not be described in detail here.

[0041] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
