Description

Technical Field

[0001] This utility model relates to the field of underwear technology, and in particular to a three-dimensional men's underwear with a seamless front pocket and crotch. Background Technology

[0002] Underwear is an essential item for people to wear. Generally speaking, men's underwear is clothing that comes into direct contact with the male genitals. Typically, men's underwear has a bulge in the front middle to support the male genitals, which is called the front pocket. The presence of the front pocket allows the genitals to have their own space, making them more comfortable to wear and avoiding prolonged contact with the skin of the inner thighs.

[0003] The existing men's underwear has a traditional and outdated structure and a complicated design. It requires the sewing of multiple pieces of fabric to form a shape. There are many seams at the seams, and the comfort at the seams is poor. They are thicker and stiffer than the surrounding fabric and lack elasticity, which can cause discomfort when in contact with the skin and affect health. At the same time, the many seams result in a lot of time-consuming production processes and low production efficiency.

[0004] To address the aforementioned shortcomings, existing technology discloses a type of underwear (publication number CN213939721U). This underwear includes a main body composed of front and back panels and a bottom seam, and also includes a lining fabric located on the front end of the main body. The front and back panels are a one-piece structure, comprising a front panel, a left back panel, and a right back panel. However, although the front and back panels are a one-piece structure, there are multiple seams when they are sewn together with the bottom seam. For example, there are two barbs at the bottom center of the one-piece front and back panel structure. The presence of these barbs makes cutting the one-piece structure difficult and laborious, and the numerous seams also reduce comfort. Compared to a rectangular bottom seam of the same height, this barb-type bottom seam results in a smaller leg opening after sewing into underwear, causing some constriction on the thighs and affecting comfort. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a three-dimensional men's underwear with no splicing on the left and right sides of the front pocket, so as to solve the technical problems of existing underwear, which, although the front and back panels are made of one piece, have many seams when sewing them with the bottom wave, making the one-piece structure of the front and back panels difficult and laborious to cut, and the fact that many seams will reduce comfort.

[0006] To achieve the above objectives, this utility model provides a three-dimensional men's underwear with a seamless front pocket and crotch, comprising a front panel, a left rear panel, a right rear panel, a first crotch layer, and a bottom wave. The two sides of the front panel are connected to the left and right rear panels. The left rear panel has a left rear panel recess at its corner, and the right rear panel has a right rear panel recess at its corner. The edge of the front panel has a first inner recess, and the first inner recess has a second inner recess. The two sides of the second inner recess are joined together to form a scrotum support. The bottom wave is sewn to the left rear panel recess, the right rear panel recess, and the first inner recess. The first crotch layer is located on the inside of the front panel, forming a first interlayer with the front panel.

[0007] Optionally, the bottom wave is set as a rectangle, and the two opposite long sides are set as arc-shaped sides, namely the first arc-shaped side and the second arc-shaped side. The first arc-shaped side is sewn to the first concave part, and the second arc-shaped side is sewn to the left rear panel concave part and the right rear panel concave part at the same time.

[0008] Optionally, the two sides of the front panel are simultaneously sewn to the left rear panel and the right rear panel, or are integrally formed and sewn together.

[0009] Optionally, the first inner crotch layer is simultaneously sewn to the front panel on both the top and bottom opposite sides, and the first inner crotch layer is also sewn to and / or sewn to the front panel on both the left and right opposite sides.

[0010] Optionally, the first inner crotch layer is provided with a first penile opening, through which the penis extends into the first interlayer.

[0011] Optionally, the first penile opening is recessed from the upper edge of the first inner crotch layer, or the first penile opening is elliptical and located in the middle of the first inner crotch layer.

[0012] Optionally, the lower edge of the first inner crotch layer is a concave arc-shaped edge, which is sewn to the bottom wave.

[0013] Optionally, it also includes a second inner crotch, which is disposed between the first inner crotch and the front panel.

[0014] Optionally, the second inner crotch includes a crotch body and side wings. The side wings are located on both sides of the crotch body and are integrally formed with the crotch body. The side wings extend to the left rear panel and the right rear panel.

[0015] Optionally, the first inner crotch layer is provided with a first penile opening and a scrotal opening, the second inner crotch layer is provided with a second penile opening, the scrotum is located between the first inner crotch layer and the second inner crotch layer through the scrotal opening, and the penis is located between the second inner crotch layer and the front panel through the first penile opening and the second penile opening.

[0016] The men's underwear with seamless left and right side panels in the front pocket provided by this utility model has the following technical effects:

[0017] This type of men's underwear with a seamless front pocket and three-dimensional crotch lining is mainly composed of a front panel, left back panel, right back panel, a first inner crotch layer, and a bottom wave. Compared with existing technology where the bottom wave requires multiple independent stitches to connect the front, left back, and right back panels, this invention integrates the left back panel recess, right back panel recess, and first inner recess with the bottom wave into a single-line stitch. This avoids the need for additional cutting processes required by the hook-and-loop structure in existing technology, and avoids the problem of the leg opening being too small and the thigh movement comfort caused by hook-and-loop bottom waves of the same height. In other words, this invention significantly reduces the number of stitches while ensuring support function by optimizing the shape of the recesses, thereby improving wearing comfort and three-dimensionality.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] In existing technologies, men's underwear typically employs a multi-panel design, with numerous stitches connecting the front pocket and the main body. This results in increased thickness and reduced elasticity at the seams. During prolonged wear, the stitched areas can rub against the skin, causing discomfort. Furthermore, the complex sewing process increases production costs. While some existing technologies offer one-piece front and back panel designs, the connection between the hem and the main body still requires multiple stitches. The hook-and-loop structure complicates the cutting process, and the leg openings for hems of the same height are often too small, failing to effectively address the problem of excessive stitching.

[0036] To address these issues, designers noticed that traditional underwear seams are concentrated in the crotch area, especially at the junction of the front pocket and the bottom wave 4, creating multiple stress points. Analysis of the seam distribution revealed that reducing the number of crotch seams effectively improves comfort. Based on this, they attempted to directly connect the front panel 1 to the left and right back panels 3, eliminating traditional side seams. Simultaneously, considering ergonomic features, the bottom wave 4 was connected to specific recessed areas, avoiding continuous seams in critical contact areas.

[0037] Therefore, this utility model proposes a men's underwear comprising a front panel 1, a left rear panel 2, a right rear panel 3, a first inner crotch layer 5, and a bottom wave 4. The following details the specific details. Figure 1-13 This invention provides a detailed description of the men's underwear with a seamless front pocket and three-dimensional crotch lining.

[0038] Example 1:

[0039] like Figure 1-4 The diagram shows the structure of the men's underwear with a seamless front pocket and a three-dimensional crotch in this embodiment. This type of men's underwear with a seamless front pocket and a three-dimensional crotch includes a front panel 1, a left back panel 2, a right back panel 3, a first layer of crotch 5, and a bottom wave 4. The front panel 1 is connected to the left back panel 2 and the right back panel 3 on both sides. A left back panel recess 21 is provided at the corner of the left back panel 2, and a right back panel recess 31 is provided at the corner of the right back panel 3. A first inner recess 11 with a second inner recess 12 is provided at the edge of the front panel 1. The two sides of the second inner recess 12 are joined together to form a scrotum support 13. The bottom wave 4 is sewn together with the left back panel recess 21, the right back panel recess 31, and the first inner recess 11. The first layer of crotch 5 is provided on the inside of the front panel 1 and forms a first interlayer with the front panel 1.

[0040] The corner recesses of the left rear panel 2 and right rear panel 3 are arc-shaped structures formed by the inward indentation of the fabric edge. Specifically, this can be achieved using a wavy cut edge, used for single-line sewing with the corresponding edge of the bottom wave 4. The first inner recess 11 of the front panel 1's edge is a recessed area extending inward from the center of the fabric, with a smaller second inner recess 12 further provided on its inner side, forming a three-dimensional support space through this double-recessed structure. The bottom wave 4 is sewn to multiple recesses by aligning the arc-shaped edge of the rectangular bottom wave 4 with the left rear panel recess 21 of the left rear panel 2, the right rear panel recess 31 of the right rear panel 3, and the first inner recess 11 of the front panel 1, respectively, and connecting them with a single stitch. The first inner crotch 5, located inside the front panel 1, is formed by covering the inner surface of the front panel 1 with an independent cut piece, and the edges of the two are connected by stitching to form a closed interlayer space.

[0041] In existing technologies, the bottom wave 4 requires multiple independent seams to connect with the front panel 1, left rear panel 2, and right rear panel 3. However, this embodiment utilizes a concave structure to integrate them into a single-line stitch. Compared to the patent with publication number CN213939721U, its barbed section structure requires additional cutting processes and still retains multiple seams. This embodiment significantly reduces the number of seams by optimizing the concave shape, while ensuring support function. The same height bottom wave increases the width of the trouser leg opening, improving wearing comfort and three-dimensionality.

[0042] Detailed, such as Figure 4 As shown, the bottom wave 4 is preferably rectangular, and the two opposite long sides are set as convex arc-shaped sides, namely the first arc-shaped side and the second arc-shaped side. The first arc-shaped side is sewn to the first inner concave part 11, and the second arc-shaped side is sewn to the left rear concave part 21 and the right rear concave part 31 at the same time.

[0043] The two long sides of the bottom wave 4 feature an outwardly convex arc design, allowing the fabric to naturally conform to the edge curves of the concave parts of the front panel 1 and the back panel during sewing. The seam only needs to extend along the arc edges to simultaneously complete multiple connections between the bottom wave 4 and the front panel 1, the left back panel 2, and the right back panel 3. Because the rectangular structure and outwardly convex arc edges of the bottom wave 4 adapt to the stretching needs of the human body during movement, there is no need to additionally cut the backstitch during sewing. The bottom wave of the same height increases the width of the trouser leg opening, and the total length of the seam is shortened and the seam is more concentrated.

[0044] In addition, the two sides of the front panel 1 can be integrally formed with the left rear panel 2 and the right rear panel 3, or they can be sewn together.

[0045] One-piece molding involves cutting a single piece of fabric to form a continuous structure from the front panel 1, left rear panel 2, and right rear panel 3, eliminating seams between components. Seaming involves connecting the edges of the front panel 1 to the left rear panel 2 and right rear panel 3 with stitches, specifically using flat stitching or elastic overlock stitching, with the number of stitches controlled to a single stitch.

[0046] Specifically, the connection method between front panel 1 and left back panel 2 and right back panel 3 is limited to two options: one is that front panel 1, left back panel 2 and right back panel 3 are cut and formed on the same piece of fabric without additional splicing seams; the other is that the edge of front panel 1 is only sewn once to left back panel 2 and right back panel 3 respectively.

[0047] like Figure 5 As shown, this embodiment only includes the first inner crotch 5. The upper and lower opposite sides of the first inner crotch 5 are simultaneously sewn to the front panel 1, while the left and right opposite sides of the first inner crotch 5 are either sewn to or not sewn to the front panel 1.

[0048] In this case, the upper and lower edges of the inner crotch are simultaneously sewn to the front panel 1 on opposite sides. For the left and right sides to be sewn to the front panel 1, the left and right sides of the inner crotch can be fully sewn, partially sewn, or intermittently sewn.

[0049] Specifically, by sewing the entire upper and lower edges of the inner crotch to the front panel 1, a stable longitudinal support structure is formed in the inner crotch. The left and right edges employ selectable sewing methods, reducing the length of lateral seams while meeting basic fixation requirements. For example, when the left and right edges are sewn only at the front third, the unsewn area at the back can naturally deform with body movement. This sewing method maintains the positioning function of the inner crotch while reducing friction between the sutures and the inner thigh skin.

[0050] like Figure 6 The diagram shows the structure of different first-layer inner crotch 5. The first-layer inner crotch 5 is made of mesh breathable material. It can be a whole piece of cloth structure or it can be provided with a first penile opening 51, which is mainly used to guide the penis into a specific space. The first penile opening 51 can also be provided with various shapes. The penis can be inserted into the first interlayer through the first penile opening 51. The first interlayer refers to the gap between the first-layer inner crotch 5 and the front panel 1.

[0051] like Figure 6 As shown, the first penile opening 51 can be formed by an indentation from the upper edge of the first inner crotch 5, or it can be an oval shape located in the middle of the first inner crotch 5.

[0052] See also Figure 6 As shown, the upper edge of the first inner crotch 5 is a straight edge, and the lower edge of the first inner crotch 5 is a concave arc edge, which is sewn to the bottom wave 4.

[0053] The upper edge of the first inner crotch 5 is fixedly connected to the inner side of the front panel 1 via a straight edge, and the lower edge is sewn to the corresponding edge of the bottom wave 4 via a concave arc edge. The straightness of the straight edge ensures that the seam between the inner crotch and the front panel 1 remains a single line segment, while the concave arc edge matches the arc contour of the bottom wave 4 through its curved shape.

[0054] Example 2

[0055] This embodiment adds a second inner crotch 6 to the existing embodiment 1, such as... Figure 7-10 As shown, the second inner crotch 6 is made of a mesh breathable material and is located between the first inner crotch 5 and the front panel 1. That is, a gap can be formed between the front panel 1 and the first inner crotch 5, and a gap can also be formed between the first inner crotch 5 and the second inner crotch 6.

[0056] The second inner crotch 6 refers to the independent structural layer located between the first inner crotch 5 and the front panel 1. Like the first inner crotch 5, the second inner crotch 6 can also be made of elastic fabric cut into a sheet structure.

[0057] Detailed, such as Figure 10 As shown, the second inner crotch 6 includes a crotch body 61 and side wings 62. The side wings 62 are located on both sides of the crotch body 61 and are integrally formed with the crotch body 61. The side wings 62 extend to the left rear panel 2 and the right rear panel 3.

[0058] The crotch body 61 is the main load-bearing area of ​​the second inner crotch 6. Specifically, it can adopt an arc-shaped contour design that matches the curvature of the human crotch to distribute crotch pressure and improve support.

[0059] The side wings 62 are strip-shaped structures extending outward from both sides of the crotch body 61. Specifically, they can be integrally formed from the same material as the crotch body 61. Their extension length can cover the connection area between the left rear panel 2 and the right rear panel 3, thereby enhancing the overall stability of the crotch structure.

[0060] The shape of the first inner crotch 5 in this embodiment is still referred to. Figure 9 As shown, each shape can be freely combined with the second inner crotch 6.

[0061] Example 3

[0062] The difference between this embodiment and embodiment 2 is that, Figure 11-13 As shown, the shape of the first inner crotch 5 is different. In this embodiment, in addition to the first penile opening 51, the first inner crotch 5 may also have a scrotal opening 52. The second inner crotch 6 has a second penile opening 63 or the second inner crotch 6 is a complete piece of fabric.

[0063] When the first inner crotch 5 has both a first penile opening 51 and a scrotum, the scrotum is located between the first inner crotch 5 and the second inner crotch 6 through the scrotum opening 52. When the second inner crotch 6 has a second penile opening 63, the penis is located between the second inner crotch 6 and the front panel 1 through the first penile opening 51 and the second penile opening 63.

[0064] Specifically, the scrotum is confined between the first inner crotch 5 and the second inner crotch 6 through the scrotal opening 52, while the penis passes sequentially through the first penile opening 51 and the second penile opening 63, ultimately residing within the second layer formed by the second inner crotch 6 and the front panel 1. By providing two layers of inner crotches and corresponding openings, the reproductive organs are independently and layered, preventing the scrotum and penis from being compressed against each other in a single space.

[0065] The structure of this embodiment improves the overall functionality of men's underwear, including enhanced breathability to keep dry, optimized structure to improve comfort and support, meeting the higher demands for absorbency, comfort and functionality of underwear in different scenarios (such as daily wear, sports, etc.), and improving the shortcomings of traditional underwear with simple structure and insufficient function.
