Technical Field

[0001] The utility model relates to the technical field of underwear support, in particular to a hollow cup structure and a bra. Background Art

[0002] Due to the structural characteristics of the human chest, the chest has different support requirements for different parts of the underwear.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Due to the structural characteristics of the human chest, the chest has different support requirements for different parts of the underwear. Specifically, the upper and inner sides of the human chest require less support, and the flexibility requirements of the cup structure corresponding to the upper and inner sides of the human chest are higher, while the lower and outer sides of the human chest require greater support, and the upper and inner sides of the human chest require less flexibility and higher support. In the prior art, underwear often adopts an integrated design, and the overall flexibility and support strength of the underwear are not much different. If the overall hardness of the underwear is large and the support force is strong, the upper and inner sides of the human chest will easily form pressure on the human chest. If the overall hardness of the underwear is small and the support force is weak, the underwear support strength corresponding to the lower and outer sides of the human chest will be too small, which is difficult to meet the shaping support requirements of the human chest, and the overall support efficiency of the underwear will be reduced accordingly. Therefore, the support of the chest by the underwear of the prior art is difficult to meet the requirements of different support forces and flexibility in various areas of the chest, and the wearing experience of the underwear is poor.

[0039] To solve the above technical problems, Figures 1 to 4 As shown, the present application proposes a hollow cup structure 100 , which includes a first base layer 110 and a first support layer 120 .

[0040] like Figure 1 As shown, the first support layer 120 and the first base layer 110 are stacked along the first direction X, and the first support layer 120 is provided with a first area 121 and a second area 123. The first area 121 is used to fit the upper side of the human chest, and the second area 123 is used to fit the lower side of the human chest. The first area 121 is provided with a main hole 122, and the second area 123 is provided with an auxiliary hole 124. In the direction perpendicular to the first direction X, the projection area of ​​a single hole of the main hole 122 on the first base layer is not less than the projection area of ​​a single hole of the auxiliary hole 124 on the first base layer. According to different processing requirements, the main hole 122 and the auxiliary hole 124 can be obtained by any suitable method. Specifically, the main hole 122 and the auxiliary hole 124 can be obtained by laser cutting. It should be noted that the main hole 122 and the auxiliary hole 124 on the first support layer 120 can be through holes or blind holes, which are not limited here. The first base layer 110 can be a fabric layer or a combination of multiple material layers. To facilitate cutting, the first supporting layer 120 may be configured as a sponge foam layer.

[0041] In the technical solution of the present application, the hollow cup structure 100 has a first area 121 and a second area 123. The first area 121 is provided with a main hole 122, and the second area 123 is provided with an auxiliary hole 124. In the direction perpendicular to the first direction X, the projection area of ​​a single hole of the main hole 122 on the first base layer is not less than the projection area of ​​a single hole of the auxiliary hole 124 on the first base layer. The first supporting layer 120 corresponding to the first area 121 has the largest hollow hole, so that the supporting material per unit area of ​​the first area 121 is the least, the supporting strength of the first area 121 is reduced, and the flexibility is improved. The hollow cup structure 100 corresponding to the first area 121 has good elasticity, so that the hollow cup structure 100 can better wrap and fit the upper side of the human chest.

[0042] In the prior art, in order to enhance the supporting efficiency of the center point of the cup, some cups make the part of the cup close to the inner side of the human chest have a greater hardness, so that the inner side of the cup does not have enough elasticity and space. When wearing, the cup will cause pressure on the human chest, which not only makes the wearing aesthetically pleasing, but also causes breathing difficulties and affects health. In the technical solution of the present application, the area of ​​a single hole of the hollowed-out auxiliary hole 124 in the second zone 123 is smaller than the area of ​​a single hole of the main hole 122. On the one hand, the setting of the auxiliary hole 124 can reduce the supporting material of the second zone 123, improve the flexibility of the second zone 123, enhance the fit between the hollow cup structure 100 corresponding to the second zone 123 and the human chest, and reduce the pressure of the hollow cup structure 100 on the human chest. On the other hand, compared with the main hole 122, the area of ​​a single hole of the auxiliary hole close to the lower side of the human chest is small, the first supporting layer 120 has less material removed, and more supporting material is retained per unit area. The second zone 123 can fit the human chest while also having good supporting efficiency. The reasonable distribution of the hollow holes in the first area 121 and the second area 123 makes the hollow cup structure 100 in the technical solution of the present application have reasonable flexibility distribution, strong supporting ability and high wearing comfort.

[0043] According to the different requirements of flexibility and support performance of different models of hollow cup structures 100, the actual size and number of the main hole 122 and the auxiliary holes 124 may be different. Specifically, the main hole 122 may have only one single hole, and the projection area of ​​the hole along the first direction X on the first base layer 110 is larger than the projection area of ​​any hole in the auxiliary holes 124 on the first base layer. The main hole 122 may also have multiple holes, wherein the projection area of ​​at least one hole among the multiple holes along the first direction X on the first base layer 110 is larger than the projection area of ​​any hole in the auxiliary holes 124 on the first base layer. Similarly, the auxiliary hole 124 may have only one hole or multiple holes. Preferably, as Figure 1As shown, in this embodiment, the auxiliary holes 124 include a first hole group 1241, a second hole group 1242 and a third hole group 1243. The first hole group 1241 is arranged on the side of the main hole 122 close to the inner side of the human chest. The second hole group 1242 is arranged on the side of the main hole 122 close to the outer side of the human chest. The third hole group 1243 is arranged on the side of the main hole 122 close to the lower side of the human chest. A hole group refers to an array composed of a plurality of holes. The provision of a plurality of hole groups makes the flexibility of the second area 123 more refined and diversified, and the hollow cup structure 100 can have a richer flexibility distribution, and at the same time can better adjust the support efficiency of each area. As shown in FIG. Figure 4 As shown, in some embodiments, the auxiliary holes 124 include a first hole group 1241 and a third hole group 1243. The hole groups specifically included in the auxiliary holes 124 and the number of holes in the hole groups can be set according to different usage requirements and are not limited here.

[0044] In some embodiments, in order to adjust the flexibility of the hollow cup close to the inner side of the human chest, the widths of the holes in the first hole group 1241 may be different. Similarly, the widths of the holes in the second hole group 1242 may also be different. Figure 1 As shown, in this embodiment, the second direction Y points from the outside of the human chest to the inside of the human chest, and the second direction Y is perpendicular to the first direction X. The auxiliary holes 124 include a first hole group 1241, which is disposed on the side of the main hole 122 close to the inside of the human chest, and the width of the holes of the first hole group 1241 close to the inside of the human chest along the second direction Y is greater than the width of the holes away from the inside of the human chest along the second direction Y. The auxiliary holes 124 include a second hole group 1242, which is disposed on the side of the main hole 122 close to the outside of the human chest, and the width of the holes of the second hole group 1242 close to the outside of the human chest along the second direction Y is not greater than the width of the holes away from the inside of the human chest along the second direction Y. That is to say, more supporting materials are removed from the corresponding holes of the first hole group 1241 within a unit area close to the inner side of the human chest, and less supporting materials are removed from the corresponding holes of the second hole group 1242 within a unit area close to the outer side of the human chest. The flexibility of the hollow cup structure 100 close to the inner side of the human chest is stronger than the flexibility of the hollow cup structure 100 close to the outer side of the human chest. On the contrary, the supporting efficiency of the hollow cup structure 100 close to the inner side of the human chest is lower than the supporting efficiency of the hollow cup structure 100 close to the outer side of the human chest, and the flexibility of the cup and the rationality of the distribution of the supporting efficiency are further improved.

[0045] In order to adjust the flexibility and support performance of the hollow cup structure 100, not only can the size and shape of the holes be designed according to different needs, but also the distance between the holes can be adjusted according to different needs. Figure 1As shown, in this embodiment, the auxiliary holes 124 include a first hole group 1241 and a second hole group 1242. The first hole group 1241 is arranged on the side of the main hole 122 close to the inner side of the human chest, and the second hole group 1242 is arranged on the side of the main hole 122 close to the outer side of the human chest. The second direction Y points from the outer side of the human chest to the inner side of the human chest, and the second direction Y is perpendicular to the first direction X. The spacing between adjacent holes in the first hole group 1241 along the second direction Y is not greater than the spacing between adjacent holes in the second hole group 1242 along the second direction Y. Specifically, along the second direction Y, the distance between adjacent holes in the first hole group 1241 can be gradually reduced, and the distance between adjacent holes in the second hole group 1242 can also be gradually reduced. The minimum spacing between adjacent holes in the second hole group 1242 can be greater than the maximum spacing between adjacent holes in the first hole group 1241. According to different design requirements, the main hole 122 and the auxiliary hole 124 can be configured as any one or more of circular holes, heart-shaped holes, star-shaped holes, diamond-shaped holes, triangular holes, pentagonal holes, hexagonal holes, octagonal holes or snowflake-shaped holes.

[0046] The stretch rate refers to the ratio of the elongation of the original gauge length to the original gauge length after the specimen is stretched and broken. In some embodiments, the first zone has a first stretch rate a, the second zone has a second stretch rate b, the first support layer also has a third zone, the third zone is arranged around the first zone and the second zone, the third zone has a third stretch rate c, and the first stretch rate a, the second stretch rate b and the third stretch rate c satisfy c≤b≤a. Specifically, in order to ensure the support efficiency while meeting the flexibility, the first zone 121 can have a first stretch rate a, and the first stretch rate a satisfies: 0.4≤a≤0.7. Specifically, the first stretch rate a can be any suitable value such as 0.4, 0.5, 0.65 or 0.7. The second zone 123 can have a second stretch rate b, and the second stretch rate b satisfies: 0.3≤b≤0.6. Specifically, the second stretch rate b can be any suitable value such as 0.3, 0.4, 0.45, 0.56 or 0.6. The first supporting layer 120 may also have a third area 125, the third area 125 is arranged around the first area 121 and the second area 123, and the third area 125 has a third stretching rate c, and the third stretching rate c satisfies: 0.2≤c≤0.6. The third stretching rate c can be any suitable value such as 0.2, 0.3, 0.45, 0.5 or 0.6. In other words, in the first supporting layer 120, the third area 125 has the strongest supporting performance. It should be noted that the third area 125 may be provided with hollow holes or may not be provided with hollow holes, and the supporting performance of the first base layer 110 may be stronger than that of the third area 125. When the third area 125 is provided with hollow holes, the hollow holes of the third area 125 are the fourth hole group 1251, and the holes of the fourth hole group 1251 can be used to enhance the air permeability of the hollow cup and adjust the flexibility and supporting performance of the edge of the hollow cup structure 100. Similarly, the main hole 122 and the auxiliary hole 124 can also improve the breathability of the underwear, and the details will not be repeated here.

[0047] Along the first direction X, the first support layer 120 may be provided with a first base layer on one side and a second base layer on the other side. Both the first base layer and the second base layer may include fabric, sponge foam, mesh glue, etc. Specifically, Figure 1 As shown, in this embodiment, the hollow cup structure 100 further includes a second base layer 130, which is disposed on the side of the first support layer 120 away from the first base layer 110, and the second base layer 130 covers the first support layer 120. The first base layer 110 includes a first fabric layer 111, a first foam layer 112, and a first colloid layer 113 which are stacked, and the first colloid layer 113 is used to bond the first foam layer 112 to the first support layer 120. If the first base layer 110 is used to fit the human chest, the second base layer 130 is disposed on the side of the first support layer 120 away from the human chest, such as Figure 3As shown, in some embodiments, the second base layer 130 includes a second foam layer 131 and a second fabric layer 132, and the hollow cup structure 100 can be stacked in sequence along the first direction X with a first fabric layer 111, a first foam layer 112, a first colloid layer 113, a first support layer 120, a second foam layer 131 and a second fabric layer 132. Under the gravity of the entire human chest, the lower side of the hollow cup structure 100 must have sufficient support to hold up the chest, and the provision of multiple sponge foam layers can effectively improve the support efficiency of the hollow cup structure 100. During processing, the colloid layer can make each layer tightly combined. After molding, the hollow cup structure 100 is thin, flexible, and has high support efficiency. The hollow cup structure 100 can also provide sufficient support in different sizes. In addition, the first colloid layer 130 can be configured as hot melt adhesive, polyurethane (PU), ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), etc., and the bonding between the material layers can be heated and bonded with hot melt adhesive. Since hot melt adhesive is composed of many soft segments and hard segments, it has advantages such as good elasticity and excellent elongation. The hot melt adhesive bonding cost is low and helps to eliminate steps such as clamping, fixing and drying, thereby saving time, energy and space in processing, improving production efficiency, and greatly improving product quality.

[0048] During the manufacturing process, different materials can be provided for laser cutting, lamination and molding to obtain the hollow cup structure 100. Specifically, the first step is to select a suitable foam material according to different hardness and density, and cut the foam material into appropriate size and shape by a mold or a cutting tool. In the second step, the pattern and depth of laser cutting can be defined and optimized using software such as CAD, and then the first support layer 120 with a main hole 122 and additional holes can be obtained by laser cutting. Specifically, based on design requirements, a computer-controlled laser cutting system can be used to adjust laser parameters such as the power, focal length, speed and intensity of the laser laser to obtain hollow holes of different depths. In addition, the materials for laser cutting in this application can be placed on a vertical bottom plate with good air permeability, easy to clean and easy to disassemble for cutting. The focal length lens of the laser gun will also affect the accuracy of the size of the laser pattern. Preferably, a focal length lens with a focal length of 60° to 80° can be selected. The larger the focal length of the focal length lens, the longer the focal point, and the thicker the thickness of the laser cut piece can be. The laser cutting system cuts the foam material through a high-precision laser beam according to the predetermined pattern and parameters to form the required flexibility change area. The third step is to assemble the cut materials in layers. Because there is a laser-cut pattern between the fabric trim and the sponge layer, the adhesion requirement is quite high, because the contact surface will be less than that of ordinary cotton cups. The setting of hot melt adhesive can make the connection between the layers more stable. In addition, the appropriate glue or structural material fixes the laminated foam material together, which can also improve the stability and durability of the cup shape. The fourth step is molding. Place the laminated foam materials in the mold to ensure that they fit the requirements of the cup shape.

[0049] like Figure 1 as well as Figure 2 As shown, in some embodiments, the hollow cup structure 100 includes a first cup body 200 and a second cup body 300, the first cup body 200 includes a first base layer and a first support layer 120, the second cup body 300 includes a third base layer and a second support layer 320, and the second support layer 320 has a hole group symmetrically arranged with the main hole 122 and the auxiliary hole 124. The first cup body 200 and the second cup body 300 can be used to support the left and right breasts of the human body respectively. The second cup body 300 has holes symmetrical to the first cup body 200, and the second cup body 300 can have the same material layer as the first cup body 200. The advantages of the second cup body 300 are the same as those of the first cup body 200, which will not be repeated here.

[0050] like Figure 2 As shown, the second aspect of the present application further provides a bra 10, which includes the hollow cup structure 100 of any of the above embodiments. Thanks to the improvement of the above hollow cup structure 100, the hollow cup structure 100 of this embodiment has the same technical effect as the above hollow cup structure 100, which will not be repeated here.

[0051] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0052] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
