Description

TECHNICAL FIELD

[0001] The present application relates to the field of garment manufacturing, in particular to a bra with double-layered cups. BACKGROUND

[0002] From the manufacturing process, the bra can be generally classified into two types: the sewn bra and the molded bra. The sewn bra mainly relies on manual sewing, which is not only complicated and time-consuming, but also difficult to guarantee the quality and consistency of the bra, and brings the problems of low production efficiency and uncontrollable cost. In order to solve the above technical problems, the molded bra is proposed, which uses hot pressing technology to press and form multiple layers of materials under high temperature and high pressure. This manufacturing method not only simplifies the manufacturing process and reduces the production cost, but also greatly improves the production efficiency. For example, the Chinese patent CN200510102253.0 discloses a method for making a bra, which includes the following steps: making a mold; making cloth cotton; fixing the steel ring sleeve between the first sponge layer and the second sponge layer to form an inner container by using high-temperature pressing method; spraying glue on the inner container; placing the prepared inner container between the two layers of cloth cotton, and using high-temperature bonding, pressing and forming to cut into the main body of the bra. The entire manufacturing process of the main body is carried out by using high-temperature bonding and pressing forming method, which is simple in process and high in production efficiency. At the same time, the main body part has no sewing and stitching, and the appearance is beautiful and comfortable to wear. SUMMARY

[0003] After in-depth analysis of the bra disclosed in patent CN200510102253.0, it is found that although the bra of this type overcomes the problems of low production efficiency and poor product consistency of the traditional sewn bra, it is worth noting that since the two layers of cloth and the inner liner are bonded together, the air permeability is poor, and it is easy to cause a stuffy feeling during long-term wearing, thereby affecting the comfort experience of wearing. In order to solve the above technical problems, the present inventors propose a double-layer structure of the cup, the cup includes an outer side cover and an inner side cover, the outer side cover and the inner side cover are not bonded together so that a breathable layer is formed between them. However, other technical problems are derived: first, the cup formed by molding is generally a general cup type, and it needs to be trimmed into different shaped cups at a later stage. After trimming the shape of the cup, for example, trimming the upper edge of the outer side cover and the inner side cover, an opening is cut on the outer side cover and the inner side cover at the same time, which destroys the original stable structure between the outer side cover and the inner side cover, causing most of the inner side cover to be lifted up. When trying to fix the two parts of the cut opening together again, the inner side cover is easily dragged and dislocated with the outer side cover, and the relative positions of the two need to be adjusted repeatedly, making the entire fixing process very cumbersome and time-consuming, greatly delaying the production efficiency. Second, during transportation, the outer side cover and the inner side cover are prone to wrinkles, affecting the appearance effect.

[0004] One of the purposes of the present application is to propose a new breathable bra that helps to simplify the fixing operation after trimming the cup type.

[0005] In view of this, the present application proposes a bra containing a double-layer cup, which includes an outer material layer and a skin-contacting material layer stacked on the inner side of the outer material layer, the outer material layer has a pair of left and right arranged outer side covers and an outer side connecting portion connecting the pair of outer side covers together, the skin-contacting material layer has a pair of left and right arranged inner side covers and an inner side connecting portion connecting the pair of inner side covers together; the outer side cover and the inner side cover are stacked together to form a cup for accommodating the breast; characterized in that the outer edge of the inner side cover is fixed on the outer material layer, the middle part of the inner side cover is adhered to the outer side cover, and the adhesion between them is F1; the inner side connecting portion and the outer side connecting portion are bonded and fixed together, the adhesion between the inner side connecting portion and the outer side connecting portion is F2, F1 is less than F2; when the middle part of the inner side cover is pulled inward, the middle part of the inner side cover can be peeled off from the outer side cover.

[0006] According to the above technical scheme, compared with the prior art, the beneficial technical effects of the present application are that: the middle part of the inner cover is adhered to the outer cover, and the adhesion force between them is F1; the inner connecting part and the outer connecting part are fixedly bonded together, and the bonding force between the inner connecting part and the outer connecting part is F2, F1 is less than F2; when the middle part of the inner cover is pulled inward, the middle part of the inner cover can be peeled off the outer cover, so that before the middle part of the inner cover is peeled off the outer cover, the trimming process is convenient, and after the trimming is completed, the trimming opening of the inner cover and the outer cover can also be fixed together very conveniently, and during transportation, the inner cover and the outer cover are also not easy to wrinkle and damage the original appearance effect. In the actual use process of the bra, the inner cover can be peeled off the outer cover without damaging the inner cover, but the same force cannot peel the inner connecting part off the outer connecting part. After peeling, a breathable layer is naturally formed between the inner cover and the outer cover, and the breathability of the cup is optimized.

[0007] Further technical solutions can also be that the outer material layer includes a fabric layer and a sponge layer, the sponge layer is stacked between the fabric layer and the skin-contacting material layer; a glue layer is arranged between the sponge layer and the inner connecting part, and no glue layer is arranged between the sponge layer and the inner cover; the sponge layer and the inner connecting part are fixedly bonded together under the action of the glue layer, and the sponge layer and the inner cover are bonded together by hot molding.

[0008] Further technical solutions can also be that a first glue layer is arranged between the outer material layer and the inner connecting part, a second glue layer is arranged between the outer material layer and the inner cover, and the adhesion of the first glue layer is greater than that of the second glue layer.

[0009] Further technical solutions can also be that the inner cover and the inner connecting part are in a split structure and are spliced together, the splicing outer edge part of the inner cover that is spliced with the inner connecting part is arranged between the sponge layer and the glue layer, and the glue layer not only fixes the inner connecting part to the sponge layer, but also fixes the splicing outer edge part of the inner cover to the inner connecting part.

[0010] Further technical solutions can also be that the outer edge part of the inner cover that is not spliced with the inner connecting part is fixedly connected to the outer material layer.

[0011] Further technical solutions can also be that a first adhesive layer is arranged between the outer connecting part and the inner connecting part, a second adhesive layer is arranged between the outer cover part and the inner cover part, and the adhesive force of the first adhesive layer is greater than that of the second adhesive layer.

[0012] Further technical solutions can also be that the inner cover part and the inner connecting part are in an integrated structure.

[0013] Further technical solutions can also be that the inner cover part is a natural fabric cover part.

[0014] Further technical solutions can also be that the natural fabric cover part is a silk cover part.

[0015] Further technical solutions can also be that the natural fabric cover part is a silk cover part. BRIEF DESCRIPTION OF DRAWINGS

[0017] Figure 2 is Figure 1 is a schematic diagram of the inner structure of a bra containing a double-layered cup according to the technical solutions of the present application; DETAILED DESCRIPTION

[0018] The structure of a bra containing a double-layered cup according to the technical solutions of the present application will be further described below in combination with the drawings. Except for explicitly stated equivalent or alternative embodiments, the various embodiments disclosed below can be selectively applied or combined in one embodiment even if they are not directly related or coordinated in terms of function.

[0019] As Figure 1 and 2The bra with the cup with the double-layer structure is shown, and the bra comprises an outer material layer 1 and a skin-contacting material layer 2 which is stacked on the inner side of the outer material layer 1. A pair of left and right outer side cup portions 11 and an outer side connecting portion 12 which connects the pair of outer side cup portions 11 together are formed on the outer material layer 1. A pair of left and right inner side cup portions 21 and an inner side connecting portion 22 which connects the pair of inner side cup portions 21 together are formed on the skin-contacting material layer 2. The outer side cup portion 11 and the inner side cup portion 21 are stacked together to form a cup for accommodating a breast. The outer edge portion of the inner side cup portion 21 is fixed on the outer material layer 1, the middle portion of the inner side cup portion 21 is adhered to the outer side cup portion 11, and the adhesion force between them is F1. The inner side connecting portion 22 and the outer side connecting portion 12 are adhered and fixed together, and the adhesion force between the inner side connecting portion 22 and the outer side connecting portion 12 is F2. F1 is less than F2. When the middle portion of the inner side cup portion 21 is pulled inward, the middle portion of the inner side cup portion 21 can be peeled off the outer side cup portion 11.

[0020] In the state of wearing the bra, the skin-contacting material layer 2 is close to and directly contacts the human body, and the outer material layer 1 is away from the human body relative to the skin-contacting material layer 2. The skin-contacting material layer 2 is located between the outer material layer 1 and the human body.

[0021] The outer edge portion of the inner side cup portion 21 is the outer edge portion of the inner side cup portion 21. The middle portion of the inner side cup portion 21 is the central region of the inner side cup portion 21, which is located on the inner side of the outer edge portion of the inner side cup portion 21, and includes a central portion and a portion between the central portion and the outer edge portion. In this embodiment, the inner side cup portion 21 is a natural fabric cup portion, which is a silk cup portion or a linen cup portion.

[0022] The outer edge portion of the inner side cup portion 21 is fixed on the outer material layer 1. The above feature can be understood as that the position of the outer edge portion of the inner side cup portion 21 relative to the outer material layer 1 is fixed. Various fixing methods can be adopted, for example, in the technical solution of the integrated structure between the inner side cup portion 21 and the inner side connecting portion 22, the outer edge portion of the inner side cup portion 21 can be fixed on the outer material layer 1 through the inner side connecting portion 22. In the technical solution of the split structure between the inner side cup portion 21 and the inner side connecting portion 22, the outer edge portion of the inner side cup portion 21 can be adhered to the inner side connecting portion 22, the outer side cup portion 11 or the outer side connecting portion 12 of the outer material layer 1.

[0023] The middle portion of the inner side cup portion 21 is adhered to the outer side cup portion 11, and F1 is less than F2. In the process of trimming the cup, for example, the middle portion of the inner side cup portion 21 can be peeled off the outer side cup portion 11. Figure 1As shown, before the outer cover 11 is peeled off at the middle of the inner cover 21, the area B is trimmed, and thanks to the fixed positional relationship between the inner cover 21 and the outer cover 11, the trimming process becomes particularly convenient. After trimming, the trimming edges of the inner cover 21 and the outer cover 11 can also be fixed together very conveniently. During transportation, thanks to the fixed positional relationship between the inner cover 21 and the outer cover 11, the inner cover 21 and the outer cover 11 are also not prone to creasing and thus damaging the original appearance effect. In the actual use of the bra, the inner cover 21 can be peeled off from the outer cover 11 without damaging the inner cover 21, but the same force cannot peel off the inner connecting part 22 from the outer connecting part 12. After peeling, a breathable layer is naturally formed between the inner cover 21 and the outer cover 11, optimizing the breathability of the cup. In specific applications, one of the following adhesive technical solutions can be selected:

[0024] The first adhesive technical solution: the outer material layer 1 includes a fabric layer 101 and a sponge layer 102, and the sponge layer 102 is stacked between the fabric layer 101 and the skin-contacting material layer 2; an adhesive layer 3 is arranged between the sponge layer 102 and the inner connecting part 22, and no adhesive layer is arranged between the sponge layer 102 and the inner cover 21; the sponge layer 102 and the inner connecting part 22 are fixed together under the action of the adhesive layer 3, and the sponge layer 102 and the inner cover 21 are adhered together through hot molding. In this embodiment, the sponge layer 102 is made of a material such as thermoplastic polyurethane that can exhibit slight adhesion during hot molding, and the adhesive layer 3 is a hot melt adhesive layer. During processing, the outer material layer 1 and the skin-contacting material layer 2 are molded by the hot molding mold, and the molding temperature is 180°-200°, and the molding time is 150s-200s. During this process, the adhesive layer 3 melts to bond the sponge layer 102 and the inner connecting part 22 together, and the sponge layer 102 exhibits slight adhesion to adhere the inner cover 21 together.

[0025] Further, the inner cover 21 and the inner connecting part 22 can be a one-piece structure or a split structure connected together. Figure 2 As shown, the inner cover 21 and the inner connecting part 22 are a split structure and are spliced together, the splicing outer edge part 211 of the inner cover 21 that is spliced with the inner connecting part 22 is arranged between the sponge layer 102 and the adhesive layer 3, and the adhesive layer 3 not only bonds the inner connecting part 22 to the sponge layer 102, but also bonds the splicing outer edge part 211 of the inner cover 21 to the inner connecting part 22. The outer edge part of the inner cover 21 that is not spliced with the inner connecting part 22 is fixed and connected to the outer material layer 1 by sewing or bonding.

[0026] The second adhesion technical solution: a first adhesive layer (not shown in the figure) is arranged between the outer connecting part 12 and the inner connecting part 22, and a second adhesive layer (not shown in the figure) is arranged between the outer cover part 11 and the inner cover part 21, the adhesive force of the first adhesive layer is greater than that of the second adhesive layer. Wherein, the first adhesive layer is a strong adhesive layer, which can stably fix the outer connecting part 12 and the inner connecting part 22 together for a long time, while the second adhesive layer is a weak adhesive layer, which can only temporarily connect the outer cover part 11 and the inner cover part 21 together, and when the middle part of the inner cover part 21 is pulled inward, the middle part of the inner cover part 21 can be peeled off from the outer cover part 11.
