[0026] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining this disclosure and are not intended to limit the disclosure. The described embodiments are some, but not all, of the embodiments of this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this disclosure.
[0027] like Figures 1 to 3 As shown, the embodiments of this disclosure provide an innovative one-piece long underwear design with a slimming effect, comprising: an outer garment structure 10 and an inner lining structure 20. Specifically, the outer garment structure 10 includes a front outer garment piece 11 and a back outer garment piece 12. The front outer garment piece 11 and the back outer garment piece 12 are respectively connected at the outer garment shoulder 101 and the outer garment side 102 of the outer garment structure 10. The skin-contact side of the outer garment structure 10 is provided with two adhesive film tightening parts 30, which are respectively attached to two opposite outer garment side 102 of the outer garment structure 10. The inner lining structure 20 includes an inner lining front piece 21 and a pair of cup pads 22. The pair of cup pads 22 are provided on the inner lining front piece 21. An adhesive layer 40 is provided on the inner lining front piece 21 and arranged circumferentially along the cup pads 22. The inner lining structure 20 is correspondingly attached to the skin-contact side of the outer garment front piece 11 through the adhesive layer 40.
[0028] According to the embodiments of this disclosure, the innovative one-piece long underwear with a slimming effect includes an outer garment structure 10 and an inner lining structure 20. The outer garment structure 10 is formed by connecting a front outer garment piece 11 and a back outer garment piece 12. The outer garment structure 10 has two outer garment shoulder parts 101 and two outer garment side parts 102. Each of the two outer garment side parts 102 is provided with an adhesive film tightening part 30. By providing an elastic adhesive film tightening part 30 on the outer garment side parts 102 of the outer garment structure 10, excess fat on the waist can be tightened and the waist shape can be modified to achieve a slimming effect and improve the overall aesthetics of the one-piece long underwear. By providing an adhesive layer 40 on the inner lining front piece 21, the inner lining front piece 21 can be connected to the outer garment front piece 11, improving the user's wearing comfort. By setting the adhesive layer 40 along the circumference of the cup pad 22, when the user wears it, the adhesive layer 40 can form a moderate binding force on the user's chest, shrinking the chest contour to achieve a slimming effect.
[0029] In some embodiments of this disclosure, the maximum thickness of the center of the cup pad 22 ranges from 3 to 4 mm. The cup pad 22 has an ultra-thin structure, which can prevent nipple protrusion and provide the necessary natural three-dimensional space for the breasts. It neither increases the thickness of the breasts nor completely compresses the breasts, causing excessive pressure.
[0030] In some embodiments of this disclosure, the adhesive film tightening portion 30 extends from the top edge of the outer garment side portion 102 of the outer garment structure 10 toward the bottom of the outer garment structure 10, that is, the adhesive film tightening portion 30 extends from the edge of the outer garment structure 10 at the underarm position toward the bottom of the outer garment structure 10, so that the adhesive film tightening portion 30 can tighten the outer garment structure 10 starting from the top edge of the outer garment side portion 102. Specifically, the edge of the outer garment structure 10 at the underarm position corresponds to the top edge of the outer garment side portion 102.
[0031] In some embodiments of this disclosure, such as Figure 1 , Figure 2 As shown, the film tightening part 30 is formed by a closed structure consisting of a first tightening edge 31, a second tightening edge 32 and a third tightening edge 33 connected in sequence. The first tightening edge 31 is arranged along the top edge of the outer garment side 102 of the outer garment structure 10. The second tightening edge 32 is located on the skin-contact side of the outer garment front piece 11 and is convex in the direction from the outer garment back piece 12 to the outer garment front piece 11. The third tightening edge 33 is located on the skin-contact side of the outer garment back piece 12 and is convex in the direction from the outer garment front piece 11 to the outer garment back piece 12. Along the top to bottom of the outer garment structure 10, the width of the film tightening section 30 gradually increases and then gradually decreases, meaning the width of the film tightening section 30 is greatest in the middle, indicating the greatest contraction force in the middle. The position of maximum width in the middle of the film tightening section 30 corresponds to the bottom edge of the inner lining front piece 21, maximizing the contraction of the outer garment structure 10 at this position. This position corresponds to the user's waist, achieving maximum contraction of the outer garment structure 10 at the user's waist, thus highlighting the S-curve of the user's waist and achieving a slimming effect. Specifically, the film tightening section 30 is a film sheet, the shape and size of which are designed according to the curve of the human waist, with a height range of 20-30cm and a maximum width range of 8-12cm.
[0032] In some embodiments of this disclosure, a portion of the second tightening edge 32 coincides with the edge of the side panel of the inner lining front piece 21, that is, a portion of the second tightening part near the top of the outer garment structure 10 coincides with the edge of the corresponding side panel of the inner lining front piece 21. The side panel of the inner lining front piece 21 is provided with a side panel adhesive portion. The side panel adhesive portion 43 and the adhesive film tightening portion 30 work together to make the outer garment front piece 11 more prominent in terms of bust shape. At the same time, the tightening effect of the outer garment side 102 of the outer garment structure 10 is better.
[0033] In some embodiments of this disclosure, the film tightening portion 30 is provided with a plurality of evenly arranged ventilation holes 301. The ventilation holes 301 increase air circulation channels, improve breathability, solve the problem of stuffiness and sweating during long-term wear, and achieve both shaping and comfort.
[0034] In some embodiments of this disclosure, such as Figure 1 , Figure 3 As shown, the adhesive layer 40 includes two peri-chest adhesive portions 41, an underband adhesive portion 42, two side panel adhesive portions 43, an upper chest adhesive portion 44, and two shoulder strap adhesive portions 45. Specifically, each peri-chest adhesive portion 41 corresponds to the periphery of the cup pad 22 to provide moderate binding force to the chest, shrinking the chest contour to achieve a slimming effect. The underband adhesive portion 42 corresponds to the underband of the inner lining front piece 21 to achieve a fixed connection between the underband of the inner lining front piece 21 and the skin-contacting side of the outer garment front piece 11. Each side panel adhesive portion 43 corresponds to the side panel of the inner lining front piece 21 to achieve a fixed connection between the side panel of the inner lining front piece 21 and the skin-contacting side of the outer garment front piece 11. Each shoulder strap adhesive portion 45 corresponds to the shoulder strap of the inner lining front piece 21 to achieve a fixed connection between the shoulder strap of the inner lining front piece 21 and the skin-contacting side of the outer garment shoulder 101 of the outer garment front piece 11. The upper chest adhesive portion 44 is correspondingly disposed above the two pericardial adhesive portions 41. The upper chest adhesive portion 44 extends from above one pericardial adhesive portion 41 to above the other pericardial adhesive portion 41, and the upper chest adhesive portion 44 is located below the two adhesive tape portions, so as to achieve a fixed connection between the upper part of the pericardial adhesive portion of the inner lining front piece 21 and the skin-contact side of the outer garment front piece 11.
[0035] In some embodiments of this disclosure, each adhesive portion of the adhesive layer 40 includes multiple spaced adhesive lines 401, the extension direction of which is the same as the stretching direction of each part of the inner lining front piece 21. Specifically, each adhesive line 401 of the chest perimeter adhesive portion 41 forms a closed shape along the circumference of the cup pad 22, and the multiple closed adhesive lines of the chest perimeter adhesive portion 41 are arranged sequentially in a direction away from the cup pad 22. The extension direction of each adhesive line 401 of the bottom perimeter adhesive portion 42 is the same as the length direction of the bottom perimeter of the inner lining front piece 21, that is, the adhesive line 401 extends from one side perimeter adhesive portion 43 of the inner lining front piece 21 to the other side wall adhesive portion, and the multiple adhesive lines 401 of the bottom perimeter adhesive portion 42 are spaced apart at the bottom of the inner lining front piece 21 in a direction from the bottom to the top. Each adhesive dot line 401 of the side panel adhesive portion is parallel to the edge of the side panel, and multiple adhesive dot lines 401 are spaced apart along the width direction of the inner lining front piece 21. Each adhesive dot line 401 of the upper chest adhesive portion 44 extends from one chest perimeter adhesive portion 41 to another chest perimeter adhesive portion 41, and multiple adhesive dot lines 401 are spaced apart along the length direction of the inner lining front piece 21. Each adhesive dot line 401 of the shoulder strap adhesive portion 45 extends along the length direction of the shoulder strap, and multiple adhesive dot lines 401 are spaced apart along the width direction of the shoulder strap.
[0036] The spacing between the multiple adhesive lines 401 on the upper chest adhesive part 44 is smaller than the spacing between the multiple adhesive lines 401 on the periphery adhesive part 41, the spacing between the multiple adhesive lines 401 on the upper chest adhesive part 44 is smaller than the spacing between the multiple adhesive lines 401 on the bottom band adhesive part 42, and the spacing between the multiple adhesive lines 401 on the upper chest adhesive part 44 is smaller than the spacing between the multiple adhesive lines 401 on the side band adhesive part 43.
[0037] The spacing between the multiple adhesive lines 401 on the shoulder strap adhesive part 45 is smaller than the spacing between the multiple adhesive lines 401 on the chest adhesive part 41, the spacing between the multiple adhesive lines 401 on the shoulder strap adhesive part 45 is smaller than the spacing between the multiple adhesive lines 401 on the underband adhesive part 42, and the spacing between the multiple adhesive lines 401 on the shoulder strap adhesive part 45 is smaller than the spacing between the multiple adhesive lines 401 on the side panel adhesive part 43.
[0038] In some embodiments of this disclosure, the spacing between two adjacent adhesive dots 401 is 2 to 3 mm. Within this range, the adhesive layer 40 has a good bonding effect and a certain binding force.
[0039] In some embodiments of this disclosure, each adhesive line 401 includes multiple spaced adhesive dots, with the distance between two adjacent adhesive dots ranging from 2 to 2.5 mm. Because the adhesive dots distribute pressure evenly in both the horizontal and vertical directions, the discomfort caused by strong pressure from flat sheets is avoided, ensuring a natural support for the chest and a comfortable wearing experience.
[0040] In some embodiments of this disclosure, the bottom of the outer garment structure 10 is provided with an anti-slip strip 50, which is circular along the bottom edge of the outer garment structure 10. The height of the anti-slip strip 50 ranges from 1 to 2 cm. By utilizing the friction between the anti-slip strip 50 and the skin, the one-piece long underwear can be firmly fitted to the user's abdomen, preventing it from slipping or shifting during wear, and ensuring the overall shaping effect of the structure is durable and stable.
[0041] In this embodiment, the length of the inner lining structure 20 is less than the length of the outer garment structure 10. The length of the inner lining front piece 21 of the inner lining structure 20 is less than the length of the outer garment front piece 11. The inner lining front piece 21 is sufficient to secure the chest area. In this embodiment, the shoulder portion of the inner lining front piece 21 corresponds to the shoulder portion 101 of the outer garment, and the side portion of the inner lining front piece 21 corresponds to the side portion 102 of the outer garment. The outer garment front piece 11 and the outer garment back piece 12 can be integrally formed or spliced together.
[0042] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
