Technical Field

[0001] This invention relates to the field of underwear, and more specifically, to a thin cup structure with support, gathering, and breathability. Background Technology

[0002] Thin-cup bras use bras with a maximum cup thickness of less than 6mm. Thin cups do not provide support or lift for the breasts. Support, lift, and breathability can only be achieved by adding other structures such as bra upholstery to the bra. This reduces the comfort of wearing thin-cup bras and increases the complexity of the product.

[0003] The problem with existing thin bra cups is that they cannot simultaneously provide support, lift, and breathability.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0008] Furthermore, the support layer is distributed below the BP point of the cup structure and between the underside of the cup.

[0011] Furthermore, the upper curve is a concave arc, and the vertical distance between the endpoint of the upper curve on the center side and the front edge of the cup structure is W1, 8mm≤W1≤15mm; the vertical distance between the endpoint of the upper curve on the center side and the underside of the cup is W2, 10mm≤W2≤30mm.

[0012] Furthermore, the vertical distance between the endpoint of the upper curve on the side panel and the front edge of the cup is W3, 8mm≤W3≤15mm; the vertical distance between the endpoint of the upper curve on the side panel and the underside edge of the cup is W4, 10mm≤W4≤30mm.

[0015] Furthermore, a third adhesive medium is provided between the outer layer of the cup and the support layer, and the outer layer of the cup and the support layer are bonded together.

[0016] Furthermore, on one side of the cup near the front edge of the cup structure, a first adhesive medium is provided between the outer layer and the inner layer of the cup, and the outer layer and the inner layer of the cup are bonded together.

[0017] Compared with the prior art, the thin bra cup structure with support, gathering, and breathability described in this invention has the following beneficial effects:

[0018] The thin cup structure described in this invention, which combines support, gathering, and breathability, solves the long-standing technical problem in the industry that thin cups lack these functions.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1

[0034] The problem with existing thin bra cups is that they cannot simultaneously provide support, lift, and breathability.

[0035] To solve the above technical problems, such as Figures 1-6 As shown, the applicant proposes a thin bra cup structure with support, gathering, and breathability functions. The maximum thickness of the cross-section of the bra cup structure 1 is less than 6 mm. The bra cup structure 1 includes an outer layer 11 and an inner layer 12. The outer layer 11 is disposed on the outside of the bra cup structure 1, and the inner layer 12 is disposed on the inside of the bra cup structure 1. On the side near the underside 4 of the bra cup structure 1, a receiving groove 13 is formed between the outer layer 11 and the inner layer 12, and a support layer 8 is disposed in the receiving groove 13.

[0036] The thin bra cup structure with support, gathering, and breathability described in this embodiment has the following advantages:

[0037] 1. If the entire cup has a support layer 8, the entire cup structure 1 would be rigid, compressing the breasts and not fitting properly. On the side near the underside 4 of the cup structure 1, a receiving groove 13 is formed between the outer layer 11 and the inner layer 12. The support layer 8 is placed within this groove 13. This design, on the one hand, concentrates the support force in the lower half, which is most vulnerable to stress, increasing the upward lift of the lower half of the cup structure 1 and effectively preventing breast sagging. The rigid support of the lower half provides a stable base for the upper half, allowing the entire cup to form a more stable structure under pressure, naturally improving the gathering effect. On the other hand, the upper half lacks the support layer 8, retaining the soft deformation capability of the upper cup. It can deform according to different breast shapes (especially full or slightly sagging breasts), thus fitting perfectly and avoiding the stiffness and pressure of traditional thick molded cups or rigid cups, making the wearer comfortable and free to move. During human activity, the soft upper part can stretch and contract, while the hard lower part remains stable, achieving a dynamic balance of stability and flexibility.

[0038] Second, the support layer 8 is encased in the receiving groove 13 between the outer layer 11 and the inner layer 12 of the cup. On the one hand, it optimizes the feel of the bra: the support layer 8 is located on the side near the underside 4 of the cup, and its position is fixed so that it will not directly rub against the skin, achieving "hard support and soft contact". Apart from the support area, the rest of the cup remains extremely thin and soft, making the entire bra light and burden-free. The wearer can hardly feel the presence of the cup, greatly improving freedom and comfort. On the other hand, it provides an ultimate invisible effect: the support layer 8 is invisible and will not show any marks on the outer surface of the cup, ensuring the bra's aesthetics and invisible effect. The support layer also does not contact the inner skin, avoiding the itching caused by seams or hard edges, ensuring the ultimate smoothness of the skin-contacting surface. In addition, it has high structural integrity: this "sandwich" style wrapping structure (outer layer-support layer-inner layer) makes the support layer 8 integrated with the cup structure 1, and it will not shift or deform after washing like traditional inserts or side pushers, greatly improving the product's durability and stability.

[0039] Third, the maximum thickness of the cross-section of the cup structure 1 is less than 6mm, which falls into the category of ultra-thin cups. This thickness greatly reduces the area of ​​skin that is covered by heat and sweat, making it easier for heat and sweat to dissipate through the fabric, thus fundamentally ensuring breathability.

[0040] In summary, through structural innovation, the cup structure 1 of this embodiment simultaneously possesses functions such as support, gathering, breathability, aesthetics, and comfort, while ensuring that the maximum thickness of the cross-section is less than 6mm.

[0041] It should be noted that, as Figure 1As shown, the cup structure 1 includes an upper curve and a lower curve. The upper curve is the front edge of the cup, and the lower curve is the underside edge 4 of the cup. The position corresponding to the nipple on the cup structure 1 is the BP point of the cup.

[0042] More specifically, the thickness of the support layer 8 is 0.1~0.6mm.

[0043] On the one hand, this design has an invisible effect, as the support layer 8 is extremely thin and will not leave any trace on the outer surface of the cup, ensuring the bra's aesthetics and invisibility; on the other hand, it has a low presence, and users can hardly feel the presence of the support layer 8, but the support layer 8 can still function through its physical properties, avoiding the foreign body sensation caused by traditional thicker support materials.

[0044] More specifically, the material of the support layer 8 is a special material for support structures, and the material of the support layer 8 is a material with certain plasticity and support force.

[0045] More specifically, the material of the support layer 8 undergoes thermoplastic deformation at 140~210℃; below 110℃, the material of the support layer 8 has good elasticity and strength, and does not undergo plastic deformation.

[0046] This design offers several advantages. First, it facilitates manufacturing. At high temperatures (140~210℃), the support layer 8, along with the inner cup layer 12 and the outer cup layer 11, can be hot-pressed and shaped in a mold to form a perfect three-dimensional cup shape. Second, it provides stability during wear. At room temperature and the temperature of human body wear (far below 110℃), the material recovers to a state of high elasticity and high strength without undergoing plastic deformation. This means that even if the user wears or washes the bra, as long as the temperature does not exceed 110℃, the support layer 8 can maintain its designed curvature and will not soften or collapse, ensuring long-term support.

[0047] Furthermore, the material of the support layer 8 is any material that can undergo thermoplastic deformation at 140~210℃ and has good elasticity and strength at temperatures below 110℃, and does not undergo plastic deformation.

[0048] Furthermore, the material of the support layer 8 includes, but is not limited to, PP, PE, PET and PU.

[0049] Specifically, in this embodiment, the material of the support layer 8 is PP.

[0050] Specifically, the support layer 8 is distributed below the cup BP point 3 of the cup structure 1 and between the cup underside 4.

[0051] This design, on the one hand, concentrates the support force in the lower half where the most force is needed, thereby increasing the upward support of the lower half of the cup structure 1; on the other hand, the upper half has no support layer 8, retaining the soft deformation ability of the upper cup, making it comfortable to wear, allowing for free movement, and avoiding stiffness.

[0052] Specifically, the support layer 8 is a closed curved surface shape formed by sequentially connecting the upper curve 802, the center end connecting curve 803, the lower curve 801, and the side end connecting curve 804.

[0053] Specifically, the shape of the lower curve 801 is the same as that of the cup undercut 4; along the cup undercut 4, the arc length between the endpoint of the lower curve 801 on the center position side and the center position endpoint 201 is L1, 4mm≤L1≤15mm, and the arc length between the endpoint of the lower curve 801 on the side panel side and the side panel endpoint 202 is L2, 4mm≤L2≤15mm.

[0054] This design allows the support force to be seamlessly transferred to the underband (center gore and side panels) of the bra, ensuring that the upward lifting force generated by the support layer 8 can effectively act on the entire bra structure and prevent the support layer 8 from being suspended.

[0055] Furthermore, L1 and L2 are unrelated; they can be equal or unequal, without any specific limitation.

[0056] In this embodiment, L1 and L2 are not equal; L1 is 7mm and L2 is 6mm.

[0057] Specifically, the upper curve 802 is a concave arc, and the vertical distance between the endpoint of the upper curve 802 on the center side and the front edge 2 of the cup structure 1 is W1, 8mm≤W1≤15mm; the vertical distance between the endpoint of the upper curve 802 on the center side and the underside edge 4 of the cup is W2, 10mm≤W2≤30mm.

[0058] This design ensures that the upper curve 802 is a certain distance from the front edge 2 and the underside edge 4 of the cup on the center side, guaranteeing the softness of the opening of the cup structure 1, making it easy for people with different bust sizes to wear without causing marks.

[0059] Furthermore, W1 and W2 are unrelated; they can be equal or unequal, without any specific limitation.

[0060] In this embodiment, W1 and W2 are not equal; W1 is 9 mm and W2 is 10 mm.

[0061] Specifically, the vertical distance between the endpoint of the upper curve 802 on the side panel and the underside of the cup 4 is W3, 8mm≤W3≤15mm; the vertical distance between the endpoint of the upper curve 802 on the side panel and the underside of the cup 4 is W4, 10mm≤W4≤30mm.

[0062] This design ensures that the upper curve 802 is a certain distance from the front edge 2 and the underside edge 4 of the cup on the side panel, guaranteeing the softness of the opening of the cup structure 1, making it easy for people with different bust sizes to wear without causing marks.

[0063] Furthermore, W3 and W4 are unrelated; they can be equal or unequal, without any specific limitation.

[0064] In this embodiment, W3 and W4 are not equal; W3 is 9 mm and W4 is 10 mm.

[0065] Specifically, along the profile line MM, the intersection of the upper curve 802 and the profile line MM is the upper intersection point, and the arc length between the upper intersection point and the cup BP point 3 is D1. The intersection of the lower curve 801 and the profile line MM is the lower intersection point, and the arc length between the lower intersection point and the cup BP point 3 is D. D1≥15mm, and D*20%≤D1≤D*50%.

[0066] This design avoids the support layer 8 directly pressing against the nipple (BP point) and causing pressure discomfort, while at the same time it can just support the base of the breast and provide upward support.

[0067] Specifically, a second adhesive medium 9 is provided between the inner layer 12 of the cup and the support layer 8, and the inner layer 12 of the cup and the support layer 8 are bonded together; a third adhesive medium 10 is provided between the outer layer 11 of the cup and the support layer 8, and the outer layer 11 of the cup and the support layer 8 are bonded together.

[0068] More specifically, during bonding, the second adhesive medium 9 and the third adhesive medium 10 completely cover the support layer 8.

[0069] This design ensures that the support layer 8 is bonded very firmly, preventing it from shifting, falling off, or bubbling during washing and wearing.

[0070] More specifically, the thickness of the second adhesive medium 9 and the third adhesive medium 10 is ≤0.3mm, and the specific gravity of the second adhesive medium 9 and the third adhesive medium 10 is ≤30gsm.

[0071] More specifically, the bonding strength of the second adhesive medium 9 and the third adhesive medium 10 does not decrease when the temperature is ≤110℃.

[0072] Furthermore, the second adhesive medium 9 and the third adhesive medium 10 can be hot melt adhesives, and there is no specific limitation.

[0073] In this embodiment, the second adhesive medium 9 and the third adhesive medium 10 are PUR reactive polyurethane hot melt adhesives.

[0074] The second adhesive medium 9 and the third adhesive medium 10 are PUR reactive polyurethane hot melt adhesives, which have excellent toughness and water resistance.

[0075] The second adhesive medium 9 and the third adhesive medium 10 are PUR reactive polyurethane hot melt adhesives, whose bonding strength does not decrease at ≤110℃, which perfectly matches the characteristic of the support layer 8 material that "does not deform plastically below 110℃". During high-temperature (>140℃) molding, the second adhesive medium 9 and the third adhesive medium 10 activate the bonding; when used at room temperature, the second adhesive medium 9, the third adhesive medium 10 and the support layer 8 remain stable and will not delaminate or deform due to daily wear temperature or warm water washing (usually <60℃).

[0076] When heated, the second adhesive medium 9 can bond the inner layer 12 of the cup and the support layer 8 into one piece. At a temperature not higher than 110°C, the bonded inner layer 12 of the cup and the support layer 8 cannot be separated.

[0077] When heated, the third adhesive medium 10 can bond the outer layer 11 of the cup and the support layer 8 into one piece. At a temperature not higher than 110°C, the bonded outer layer 11 of the cup and the support layer 8 cannot be separated.

[0078] Specifically, on one side of the front edge 2 of the cup near the cup structure 1, a first adhesive medium 7 is provided between the outer layer 11 and the inner layer 12 of the cup, and the outer layer 11 and the inner layer 12 of the cup are bonded together.

[0079] More specifically, the first adhesive medium 7 does not reduce its bonding strength when the temperature is ≤110℃.

[0080] Furthermore, the first adhesive medium 7 can be a hot melt adhesive, and there is no specific limitation.

[0081] More specifically, in this embodiment, the first adhesive medium 7 is a PUR reactive polyurethane hot melt adhesive.

[0082] The first adhesive medium 7 is a PUR reactive polyurethane hot melt adhesive, which has excellent toughness and water resistance.

[0083] Specifically, the material of the outer layer 11 of the cup includes a first sponge and an outer surface fabric.

[0084] The first sponge can be one type of sponge material, or two or more types of sponge materials; no specific limitation is made here.

[0085] More specifically, in this embodiment, the first sponge is a sponge material.

[0086] The outer surface fabric and the first sponge can be bonded together as one piece, or they can be separate pieces without being bonded together; no specific limitation is made here.

[0087] More specifically, in this embodiment, the outer surface fabric and the first sponge are bonded together as one piece.

[0088] Specifically, the material of the inner layer 12 of the cup includes a second sponge and an inner surface fabric.

[0089] The second sponge can be one type of sponge material, or two or more types of sponge materials; no specific limitation is made here.

[0090] More specifically, in this embodiment, the second sponge is a sponge material.

[0091] The inner surface fabric and the second sponge can be bonded together as one piece or they can be separate pieces without being bonded together; no specific limitation is made here.

[0092] More specifically, in this embodiment, the inner surface fabric and the second sponge are bonded together as one piece.

[0093] More specifically, the upper end of the heart position connecting curve 803 is connected to the endpoint of the upper curve 802, and the lower end of the heart position connecting curve 803 is connected to the endpoint of the lower curve 801.

[0094] More specifically, the connecting curve 803 at the heart position end is approximately the same as and approximately parallel to the arc shape of the front edge 2 of the cup corresponding to the heart position end.

[0095] This setting ensures that the connecting curve 803 at the center end and the arc of the front edge 2 of the cup corresponding to the center end form a parallelogram-like shape. The product feel of this parallelogram-like area is similar to that of the other areas of the front edge 2 of the cup, reducing the difference.

[0096] More specifically, the upper end of the side-end connecting curve 804 is connected to the endpoint of the upper curve 802, and the lower end of the side-end connecting curve 804 is connected to the endpoint of the lower curve 801.

[0097] More specifically, the side-end connecting curve 804 is approximately the same as and approximately parallel to the arc shape of the front edge 2 of the cup corresponding to the side-end.

[0098] This setting ensures that the side panel connection curve 804 and the arc of the front edge 2 of the cup corresponding to the side panel form a parallelogram-like shape. The product feel of this parallelogram-like area is similar to that of the rest of the front edge 2 area of ​​the cup, reducing the difference.

[0099] In preparing the thin cup structure with support, gathering, and breathability described in this embodiment, the materials of the outer cup 11, the inner cup 12, the first adhesive medium 7, the support layer 8, the second adhesive medium 9, and the third adhesive medium 10 are first placed in a mold. Through hot pressing, the second adhesive medium 9 and the third adhesive medium 10 bond the support layer 8 to the inner cup 12 and the outer cup 11 respectively. During the hot pressing process, the support layer 8 undergoes a one-time thermoplastic deformation or a second or more (including second) composite thermoplastic deformation together with the inner cup 12 and the outer cup 11 in the mold cavity. Under the combined action of the first adhesive medium 7, the second adhesive medium 9, and the third adhesive medium 10, and after cooling, a cup structure 1 with an inner support layer 8 is obtained, becoming a thin cup with support, gathering, and breathability.

[0100] Since hot pressing is an existing technology, it will not be elaborated here.

[0101] The thin cup structure with support, gathering and breathability described in this embodiment can be completed by hot pressing with a mold, which has high production efficiency and is suitable for industrial mass production. The outer layer 11, inner layer 12 and support layer 8 of the cup deform synchronously at high temperature. After cooling, the internal stress is small and the consistency of each product is good, avoiding the problems of dimensional deviation and uneven appearance caused by hand sewing of the support.

[0102] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
