Abstract
Description
Technical Field
[0001] This utility model relates to the field of trousers technology, specifically to a seamless trousers that tucks in the abdomen and lifts the buttocks. Background Technology
[0002] Currently, the production of leggings and sharkskin pants on the market mainly involves cutting, splicing, bonding, and sewing fabrics to achieve the product's fit and functionality, in order to meet women's needs for shaping and slimming pants, such as tummy control and buttock lifting.
[0003] Existing technologies primarily achieve abdominal slimming by applying a large area of elastic film, utilizing the rigidity and elasticity of the film to compress abdominal fat. However, the large area of elastic film makes it difficult for the waistband opening and recovery rate of the pants to meet ergonomic requirements. Specifically, the human waist needs a certain amount of space for extension and contraction in different movement states, such as bending over, turning, sitting down and standing up. However, the rigidity of a large area of elastic film is relatively strong, which restricts the opening of the waistband, causing the wearer to feel a significant sense of restriction in the waist when moving. Furthermore, after repeated stretching, the elasticity of the large area of elastic film will gradually decrease, and the recovery rate is difficult to guarantee. After repeated wear and activities, it will become loose and deformed, unable to fit the waist tightly. This not only affects the abdominal slimming effect but also makes the wearer feel that the pants are "not fitting," resulting in a loose and uncomfortable feeling.
[0004] Furthermore, existing technology uses a stitching method to connect the trousers, resulting in the outer and inner sides of the trousers being covered with stitches. On the one hand, during daily wear, when people engage in various activities such as walking, running, sitting, or standing up, the trousers will frequently move relative to the skin. At this time, the raised stitches will constantly rub against the skin, easily causing discomfort. On the other hand, the presence of stitches seriously damages the overall visual effect of the trousers. Utility Model Content
[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a seamless tummy-shaping and buttock-lifting panty, which can effectively solve the technical problems mentioned in the background art.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a seamless tummy-shaping and buttock-lifting pant, including a pant body, the pant body is made of two layers of fabric, the pant body includes a waistband and two pant legs, the upper end of the waistband is the waistband, the waistband has an embedded elastic support layer, the front of the waistband has a tummy-shaping area, and the back of the waistband has a buttock-lifting area.
[0007] The abdominal tightening area is inlaid with a plastic support layer, and the abdominal tightening area is provided with a body shaping print to increase pressure on the abdomen. The buttock lifting area is provided with a buttock line to improve three-dimensional support for the buttocks.
[0008] Furthermore, both the elastic support layer and the plastic support layer are jelly-like layers, and the thickness of the elastic support layer is greater than the thickness of the plastic support layer.
[0009] Furthermore, the hip line gradually rises outward from the hip peak area of the pants, forming two arc-shaped structures that lift the buttocks from both sides.
[0010] Furthermore, the inner and outer bobs of the pants are connected by adhesive bonding, and the elastic support layer and the plastic support layer are located between the two layers of fabric.
[0011] Furthermore, the body-shaping print includes two sets of twill stripes, which are symmetrically distributed with the center line of the waistband as the axis of symmetry. In the middle part of the pants, the two sets of symmetrically distributed twill stripes intersect to form a V-shaped structure, with the opening of the V-shape facing downwards.
[0012] Furthermore, the body-shaping print includes multiple sets of frame patterns arranged vertically and multiple rows of horizontal stripes. The frame patterns are composed of multiple equilateral triangles arranged closely vertically, and the horizontal stripes are interspersed between the frame patterns.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The waistband has an elastic support layer, and the tummy control area has a shaping support layer. Both the elastic support layer and the shaping support layer are made of jelly gel, which is a high-molecular material mainly composed of polyurethane and silicone.

In addition, the jelly gel layer is also highly breathable, which can quickly evaporate sweat and keep you dry.
[0015] 2. The thickness of the elastic support layer is greater than that of the plastic support layer. On the one hand, the thicker gel layer uses its high resilience to form a dynamic wrapping force, providing continuous support when the waist moves. On the other hand, the thicker gel layer can effectively prevent the waistband from rolling up. The thinner gel layer provides rigid support, maintaining a flat and shaping effect on the abdomen while avoiding discomfort caused by excessive compression of internal organs.
[0016] 3. The pants are made of two layers of fabric connected by a dotted adhesive layer. An elastic support layer and a plastic support layer are placed between the two layers of fabric. The inner and outer boning of the pants are both glued together with dotted adhesive to achieve a seamless fit of the fabric. This improves the appearance of the pants and eliminates the problem of seams rubbing against the skin.
[0017] 4. The buttock-lifting area features a buttock line to enhance three-dimensional support for the buttocks. The buttock line gradually rises from the buttock peak area of the pants towards the outside, forming two arc-shaped structures that lift the buttocks from both sides, thereby improving the buttock-lifting effect.
[0018] 5. The abdominal compression area features a shaping print designed to increase pressure on the abdomen, thereby enhancing the pressure value in the core abdominal area, achieving better shaping results, and significantly reducing the risk of marks. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figure 1-5 As shown, this utility model provides a seamless tummy-shaping and buttock-lifting pant, including a pant body, which is made of two layers of fabric 1. The pant body includes a waistband 5 and two pant legs 4. The upper end of the waistband 5 is the waistband 6. The front of the waistband 5 is provided with a tummy-shaping area 7, and the back of the waistband 5 is provided with a buttock-lifting area 9. The buttock-lifting area 9 is formed into a three-dimensional curved surface structure by a high temperature and high pressure integrated stamping process. Its curvature is adapted to the natural contour of the human buttocks, so as to achieve the function of lifting the buttocks line and optimizing the fit of the garment.
[0028] The waistband 6 has an embedded elastic support layer 2, and the tummy control area 7 has an embedded plastic support layer 3. Both the elastic support layer 2 and the plastic support layer 3 are jelly-like layers. The jelly-like layers are made of high-molecular materials, mainly polyurethane and silicone, with a bouncy, jelly-like feel. They have high resilience and strong tensile strength, and their soft texture can perfectly conform to the body's curves. Furthermore, the thickness of the elastic support layer 2 is greater than that of the plastic support layer 3. On the one hand, the thicker jelly-like layer utilizes its high resilience to form a dynamic wrapping force, providing continuous support during waist movement. On the other hand, the thicker jelly-like layer can effectively prevent the waistband 6 from rolling up. The thinner jelly-like layer provides rigid support, maintaining a flat and shaping effect on the abdomen while avoiding discomfort caused by excessive compression of internal organs. In addition, the jelly-like layer is also highly breathable, allowing sweat to evaporate quickly and keeping the body dry.
[0029] The abdominal compression area 7 is equipped with a shaping print 71 to increase pressure on the abdomen. The shaping print 71 includes two sets of diagonal stripes. The two sets of diagonal stripes are symmetrically distributed with the center line of the waistband 5 as the axis of symmetry, forming a diagonal pressure band on the abdomen, which increases the pressure value in the core area of the abdomen and achieves a better shaping effect. In addition, in the middle part of the pants, the two sets of symmetrically distributed diagonal stripes intersect to form a V-shaped structure. The opening of the V-shape faces the bottom of the pants. Through the three-point force principle, the longitudinal pressure of the abdomen is transformed into a lateral restraint force, while avoiding the pressure concentration point caused by traditional straight stripes, significantly reducing the risk of chafing.
[0030] In another embodiment, the body-shaping print 71 includes multiple sets of frame patterns 12 arranged vertically and multiple rows of horizontal pattern strips 13. The frame patterns 12 are composed of multiple equilateral triangles arranged closely vertically. The horizontal pattern strips 13 are interspersed between the frame patterns 12. The equilateral triangle frame patterns 12 provide three-dimensional support, and the horizontal pattern strips 13 form a mesh support structure to achieve a better shaping effect and reduce the risk of marks.
[0031] The buttock-lifting area 9 is provided with a buttock line 8 to improve the three-dimensional support of the buttocks. The buttock line 8 gradually rises from the buttock peak area of the pants to the outside, forming two arc-shaped structures that lift the buttocks from both sides, thereby improving the buttock-lifting effect.
[0032] The pants are made of two layers of fabric 1 connected by a dotted adhesive layer. An elastic support layer 2 and a plastic support layer 3 are placed between the two layers of fabric 1. The inner bob 11 and the outer bob 10 of the pants are both bonded with dotted adhesive, thereby achieving a seamless fit of the fabric 1. This improves the appearance of the pants and eliminates the problem of seams rubbing against the skin.
[0033] Compared to traditional technologies:
[0034] 1. The waistband 6 has an embedded elastic support layer 2, and the tummy control area 7 has an embedded plastic support layer 3. Both the elastic support layer 2 and the plastic support layer 3 are jelly gel layers. The jelly gel layer is a high-molecular material mainly composed of polyurethane and silicone. It has a bouncy, jelly-like feel, high resilience and strong stretchability. Its soft texture can perfectly conform to the body's curves. In addition, the jelly gel layer is also highly breathable, which can quickly evaporate sweat and keep you dry.
[0035] 2. The thickness of the elastic support layer 2 is greater than that of the plastic support layer 3. On the one hand, the thicker gel layer utilizes its high resilience to form a dynamic wrapping force, providing continuous support during waist movement. On the other hand, the thicker gel layer can effectively prevent the waistband 6 from rolling up, while the thinner gel layer provides rigid support, maintaining a flat and shaping effect on the abdomen while avoiding discomfort caused by excessive compression of internal organs.
[0036] 3. The pants are made of two layers of fabric 1 connected by a dotted adhesive layer. The elastic support layer 2 and the plastic support layer 3 are located between the two layers of fabric 1. The inner bob 11 and the outer bob 10 of the pants are both glued together with dotted adhesive, so as to achieve the effect of seamless bonding of fabric 1. On the one hand, it improves the aesthetics of the pants, and on the other hand, it eliminates the problem of seams rubbing against the skin.
[0037] 4. The buttock-lifting area 9 is provided with a buttock line 8 to improve the three-dimensional support of the buttocks. The buttock line 8 gradually rises from the buttock peak area of the pants to the outside, forming two arc-shaped structures that lift the buttocks from both sides, thereby improving the buttock-lifting effect.
[0038] 5. The abdominal compression area 7 is equipped with a shaping print 71 to increase pressure on the abdomen, thereby increasing the pressure value in the core abdominal area, achieving better shaping effect, and significantly reducing the risk of marks.
