Description

Technical Field

[0001] The present application relates to the field of bra underwear, and in particular to a flat, skin-friendly and adjustable underwear. Background Art

[0002] Bras are used to support and protect the breasts. With the diversification of women's clothing, a variety of bra styles have appeared on the market, such as strapless tube tops, shaping and pushing bras, inflatable adjustment bras, etc.

[0003] Current inflatable adjustment bras generally have an inflatable bag on the inner surface of the bra. During use, after the inflatable bag is inflated, the bag will appear high in the middle and low around the sides, making the side of the inflated bag close to the chest not fit the chest well, resulting in an empty cup phenomenon during wearing.

[0004] In this regard, there is also a technology on the market that sets an elastic gasket on the side close to the chest to limit the curvature of the inflated surface of the side of the bladder close to the chest to be lower than the curvature of the inflated surface of the other side away from the chest.

[0005] However, after the product is inflated, the side of the bag close to the chest still has a surface curvature, and the fit to the chest is not high. The elastic gasket increases the thickness of the airbag bag, so that after inflation, the bag is pulled by expansion, and several concave and convex wrinkles appear around the elastic gasket on the side close to the chest, which reduces the skin fit and comfort of the bag. Utility Model Content

[0006] In order to solve the problem that the airbag of the current inflatable underwear has a low degree of contact with the chest skin, the present application provides an adjustable underwear that is smooth and close to the skin.

[0007] The present application provides a smooth, skin-fitting, adjustable underwear that adopts the following technical solutions:

[0008] A flat and skin-friendly adjustable bra, comprising a bra body and an airbag assembly, wherein the bra body comprises a cup portion and a back portion connected to both sides of the cup portion, wherein the cup portion comprises two symmetrically arranged cups, a lower strip arranged at the bottom of each cup, and a heart arranged between the two cups;

[0009] The airbag assembly comprises a skin-friendly fabric layer, an adhesive layer, an inner inflatable film layer, and an outer inflatable film layer arranged in sequence, the inner surface of the adhesive layer is bonded to the outer surface of the skin-friendly fabric layer, the outer surface of the adhesive layer is bonded to the inner surface of the inner inflatable film layer, the outer surface of the inner inflatable film layer is bonded to the inner surface of the outer inflatable film layer, and an inflatable space is formed between the outer surface of the inner inflatable film layer and the inner surface of the outer inflatable film layer;

[0010] The outer surface of the outer inflation film layer is connected to the inner surface of the lower strip.

[0011] By adopting the above technical solution, the adhesive layer is bonded to the outer surface of the skin-friendly fabric layer, which can reduce the stretching force of the skin-friendly fabric layer. When the airbag assembly is inflated, the outer inflatable film layer bulges toward the cup, rather than the inner inflatable film layer bulging toward the skin-friendly fabric layer, so that the skin-friendly fabric layer can fit the chest flatly without being inflated and bulged, reducing the skin-friendly fabric layer from being pulled to stretch and cause wrinkles, thereby making the airbag assembly more fit to the human body structure, with good skin fit and good wearing comfort. Preferably, the outer inflatable film layer and the inner inflatable film layer are both soft films with stretching tension.

[0012] In addition, by providing an adhesive layer, when the inner inflatable film layer and the outer inflatable film layer are pressed and bonded, no indentations will appear on the inner surface of the skin-friendly fabric layer (the indentations only appear on the outer inflatable film layer side of the airbag assembly), making the inner surface of the skin-friendly fabric layer relatively flat and skin-friendly, and not prone to wrinkles caused by traction, thereby improving the skin fit and comfort of wearing.

[0013] Optionally, the back circumference portion is fixedly connected to both sides of the cup portion.

[0014] By adopting the above technical solution, the back band can be directly fixed when wearing to complete the wearing of the adjustable underwear, which is convenient to wear and highly practical.

[0015] Optionally, the back portion is detachably connected to both sides of the cup portion.

[0016] By adopting the above technical solution, the back part or the cup part can be replaced according to needs. If a cup of another cup size needs to be replaced, the back part and the cup part are disassembled and the cup part is replaced; if a back part of another size needs to be replaced, the back part and the cup part are disassembled to replace the back part.

[0017] Optionally, the airbag assembly has two symmetrically arranged cup areas, a lower pick area arranged at the bottom of each of the cup areas, and a heart-shaped area arranged between the two cup areas, the cup areas correspond to the cup settings of the cup part, the lower pick area corresponds to the lower pick setting of the cup part, and the heart-shaped area corresponds to the heart-shaped setting of the cup part; the outer surface of the outer inflatable film layer of the lower pick area is bonded to the inner surface of the lower pick of the cup part; the outer surface of the inner inflatable film layer of the heart-shaped area is fixedly provided with an inflating part and a deflation part.

[0018] By adopting the above technical solution, the airbag assembly can be stably connected to the underwear body, and the inflatable component can inflate the space between the outer inflatable film layer and the inner inflatable film layer in the cup area. The outer inflatable film layer expands toward the cup direction, and the airbag assembly is inflated according to the required inflation degree, so that the airbag assembly can play a role in adjusting the breast shape when the underwear is worn.

[0019] Optionally, the top of the outer surface of the outer inflation film layer in the heart-shaped area is bonded to the top of the inner surface of the heart-shaped area of ​​the cup portion.

[0020] By adopting the above technical scheme, the connection between the heart area of ​​the airbag assembly and the heart of the cup part is stably achieved. When worn, the airbag assembly is arranged corresponding to the relatively concave heart area of ​​the human body, which is not easy to cause a foreign body sensation on the chest. Preferably, the bottom of the heart area of ​​the airbag assembly is not bonded and connected to the heart of the cup part, so that the human fingers can enter between the heart area of ​​the airbag assembly and the heart of the cup part to operate the inflating part and the deflation part, making the inflation and deflation operations of the airbag assembly convenient, and the adjustable underwear can also be adjusted after wearing, which is highly practical.

[0021] Optionally, at least one arc-shaped pressing strip is provided between the outer surface of the inner inflatable film layer and the inner surface of the outer inflatable film layer, corresponding to the connection between the cup area and the lower pulling area.

[0022] By adopting the above technical solution, the arc-shaped pressing strip can divide the airbag assembly into a cup area and a lower pull-down area, wherein the area of ​​the cup area is larger than the area of ​​the lower pull-down area. When the airbag assembly is inflated, the airflow can quickly enter the cup area and inflate the inflation space between the outer inflation film layer and the inner inflation film layer of the cup area, so as to adjust the breast shape.

[0023] Optionally, the back skirt portion includes two symmetrically arranged side wing pieces, and the angle between the upper edges of the side wing pieces and the horizontal plane is 30-45°.

[0024] By adopting the above technical solution, the side wing pieces are more in line with the direction of the female armpit muscles, so that the side wing pieces do not squeeze the human body's armpits tightly, preventing the formation of accessory breasts. If the angle between the upper edge of the side wing piece and the horizontal line is less than 30°, the side wing piece is easy to tighten the back and pull the cup part backwards, forming accessory breasts, which is uncomfortable to wear; if the angle between the upper edge of the side wing piece and the horizontal line is greater than 45°, the part of the side wing piece that fits the human body is reduced, the wearing stability of the adjustable underwear becomes worse, and it is easy to slip when worn.

[0025] Optionally, at least one side of the side wing piece is provided with a silicone adhesive layer.

[0026] By adopting the above technical solution, when wearing the adjustable underwear, the silicone adhesive layer fits the human body, so that the cup can be stable and does not slip. The silicone adhesive layer can be reused, can maintain stickiness even after washing, and is breathable and water-permeable to prevent stuffiness. In addition, the silicone adhesive layer can be set on the side of the side wing away from the human body, so that the adjustable underwear can have a sticky feeling with the clothes, forming clothes with self-contained coasters, and the adjustable underwear is not easy to be misplaced with the clothes, and the clothes are not easy to slip and cause exposure, which is convenient for women to wear.

[0027] Optionally, the thickness of the silicone adhesive layer is 0.01-1 mm.

[0028] By adopting the above technical solution, the thickness of the silicone adhesive layer is moderate, which can play the role of bonding without having a strong foreign body feeling. If the thickness of the silicone adhesive layer is less than 0.01mm, it is easy to be loosely bonded; if the thickness of the silicone adhesive layer is greater than 1mm, it is easy to cause a significant foreign body feeling and discomfort when wearing.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The adhesive layer is bonded to the outer surface of the skin-friendly fabric layer, which can reduce the stretching force of the skin-friendly fabric layer and prevent it from being deformed. When the airbag assembly is inflated, the outer inflatable film layer bulges toward the cup, instead of the inner inflatable film layer bulging toward the skin-friendly fabric layer, so that the skin-friendly fabric layer can fit the chest flatly without being inflated, reducing the skin-friendly fabric layer from being pulled to stretch and cause wrinkles, thereby making the airbag assembly fit the human body structure better, with good skin-fitting and good wearing comfort;

[0031] 2. By setting the adhesive layer, when the inner inflatable film layer and the outer inflatable film layer are pressed and bonded, no indentations will appear on the inner surface of the skin-friendly fabric layer (the indentations only appear on the outer inflatable film layer side of the airbag assembly), so that the inner surface of the skin-friendly fabric layer is relatively flat, has good skin-friendliness, and is not prone to wrinkles caused by traction, thereby improving the skin-fitting and comfort of wearing;

[0032] 3. The back circumference is fixedly connected to both sides of the cup part. When wearing, the back circumference can be directly fixed to complete the wearing of the adjustable bra. It is convenient to wear and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] See also Figure 4 and Figure 7In terms of three-dimensional structure, the airbag assembly 2 includes a heart-shaped area 26 corresponding to the heart-shaped area 111 of the cup portion 11, a lower pick area 27 corresponding to the lower pick 112 of the cup portion 11, and two cup areas 28 corresponding to the two cups 113 of the cup portion 11. The height of the cup area 28 when not inflated does not exceed 2 / 3 of the height of the cup 113. Specifically, the heart-shaped area 26 is arranged between the two cup areas 28, the lower pick area 27 is arranged at the bottom of each cup area 28, and the outer surface of the outer inflation film layer 25 of the lower pick area 27 is in contact with the lower pick of the cup portion 11. The inner surface 112 is bonded and connected, specifically, it is bonded and connected extending from just below the cup area 28 to the bent part, and the top of the outer surface of the outer inflatable film layer 25 in the heart-shaped area 26 is bonded and connected to the top of the inner surface of the heart-shaped 111 of the cup part 11, and the middle and lower parts of the outer surface of the outer inflatable film layer 25 in the heart-shaped area 26 are not directly connected to the middle and lower parts of the inner surface of the heart-shaped 111 of the cup part 11, so that human fingers can enter between the heart-shaped area 26 of the airbag assembly 2 and the heart-shaped 111 of the cup part 11 to operate the inflating piece 242 and the deflating piece 243. Furthermore, at least one arc-shaped pressing strip 29 is provided between the outer surface of the inner inflatable film layer 23 and the inner surface of the outer inflatable film layer 25, corresponding to the connection between the cup area 28 and the lower strip area 27, so as to divide the inflation space between the outer surface of the inner inflatable film layer 23 and the inner surface of the outer inflatable film layer 25 into the cup 113 air cavity and the lower strip 112 air cavity. The volume of the cup 113 air cavity is larger than the volume of the lower strip 112 air cavity, and the air outlet end of the inflatable member 242 is connected to the cup 113 air cavity, the air inlet end of the air release member 243 is connected to the cup 113 air cavity, and the air outlet end of the air release member 243 is connected to the outside. When the number of arc-shaped pressing strips 29 is greater than 2, the bottom arc-shaped pressing strip 29 is connected to the edge of the airbag assembly 2, and the other arc-shaped pressing strips 29 above are close to the end of the heart-shaped area 26 and are not connected to the edge of the airbag assembly 2, so that the air cavity formed between the other adjacent arc-shaped pressing strips 29 is connected to the air cavity formed between the top arc-shaped pressing strip 29 and the edge of the airbag assembly 2. Figure 7The number of arc-shaped pressing strips 29 shown is 2, specifically including a first arc-shaped pressing strip 291 and a second arc-shaped pressing strip 292, the first arc-shaped pressing strip 291 is arranged at the bottom, and the second arc-shaped pressing strip 292 is arranged above the first arc-shaped pressing strip 291, and the first arc-shaped pressing strip 291 is connected to the edge, so that the lower air cavity formed between the first arc-shaped pressing strip 291 and the edge is not connected to the air outlet end of the inflatable member 242; and the second arc-shaped pressing strip 292 is arranged above the first arc-shaped pressing strip 291. The end of the second arc-shaped pressing strip 292 close to the heart-shaped area 26 is not connected to the edge of the heart-shaped area 26, that is, the end of the second arc-shaped pressing strip 292 close to the heart-shaped area 26 is at a distance from the edge of the heart-shaped area 26, so that the air cavity formed between the first arc-shaped pressing strip 291 and the second arc-shaped pressing strip 292 is connected to the air cavity formed between the first arc-shaped pressing strip 291 and the edge of the cup area 28 to form a cup air cavity, and the cup air cavity is connected to the air outlet end of the inflatable member 242. As designed above, when the adjustable bra is worn, the inflatable member 242 does not inflate the lower air cavity, so that the lower area 27 is closely attached to the breast base of the human body, and it is not easy to cause an empty cup in the cup area 28 due to the inflation of the breast base after inflation; and the distance between the first arc-shaped pressing strip 291 and the second arc-shaped pressing strip 292 is small, so that the volume of the air cavity formed between the first arc-shaped pressing strip 291 and the second arc-shaped pressing strip 292 is smaller than the volume of the air cavity formed between the first arc-shaped pressing strip 291 and the edge of the cup area 28, thereby making the bottom of the airbag assembly 2 From the bottom to the top, the air cavity (not inflated), the air cavity formed between the first arc-shaped pressing strip 291 and the second arc-shaped pressing strip 292 (small amount of inflation), and the air cavity (large amount of inflation) formed between the first arc-shaped pressing strip 291 and the edge of the cup area 28 form a trend of increasing inflation amount from bottom to top. In addition, combined with the fact that the height of the entire cup area 28 of the airbag assembly 2 when not inflated does not exceed 2 / 3 of the height of the cup 113, the inflated airbag assembly 2 fits the 3D arc structure of the human chest from the bottom to the top, has good skin-fitting and adjustment effect, and is not prone to an empty cup situation.

[0046] The implementation principle of a smooth, skin-fitting adjustable underwear in an embodiment of the present application is as follows: first, the skin-friendly fabric layer 21, the adhesive layer 22, and the inner inflatable film layer 23 are stacked and hot-pressed in sequence, and then the connecting piece 241 equipped with the inflatable component 242 and the deflation component 243 is fixed to the outer surface of the inner inflatable film layer 23 corresponding to the heart-shaped part 111 (the side away from the skin-friendly fabric layer 21), and then the outer inflatable film layer 25 is covered on the outer surface of the inner inflatable film layer 23, and the outer inflatable film layer 25 is pressed together with the inner inflatable film layer 23 along the edge of the lace shape according to the required lace shape of the airbag assembly 2, and corresponding to the cup 113 and the lower pull 112 of the cup part 11, along the direction of the lower edge of the cup 113, extend from the side close to the heart-shaped part 111 to the bent side. The outer inflatable film layer 25 and the inner inflatable film layer 23 are pressed together to form at least one arc-shaped pressing strip 29, so as to divide the inflated space formed between the outer inflatable film layer 25 and the inner inflatable film layer 23 into a cup air cavity and a lower draw air cavity. Finally, the airbag assembly 2 is trimmed along the lace-shaped edge, leaving a pressing edge 30 with a width of 0.3-1 cm at the edge. The pressing width of the arc-shaped pressing strip 29 is also preferably 0.3-1 cm. Then, an airbag assembly 2 having a heart-shaped area 26, a lower draw area 27, and a cup area 28 is obtained. Specifically, a connecting piece 241 with an inflatable member 242 and a deflation member 243 is fixed to the outer surface of the inner inflatable film layer 23 in the heart-shaped area. The cup air cavity is arranged corresponding to the cup area 28, and the lower draw air cavity is arranged corresponding to the lower draw area 27.

[0047] At the same time, the underwear body 1 can be prepared, and the materials of the underwear body 1 are stacked in a mold, and then the cup part 11 in which the cup 113, the lower rib 112 and the heart 111 are integrally connected is molded.

[0048] Then, the outer surface of the outer inflatable film layer 25 of the airbag assembly 2 is fixed to the inner surface of the cup part 11, specifically, the outer surface of the outer inflatable film layer 25 of the lower pick area 27 of the airbag assembly 2 is fixedly connected to the lower pick 112 of the cup part 11 extending from the longitudinal axis direction of the bottom of the corresponding cup 113 to the bending part to form a first connection area 251, and the top of the outer surface of the outer inflatable film layer 25 of the heart area 26 of the airbag assembly 2 is fixedly connected to the top of the heart 111 of the cup part 11 to form a second connection area 252; finally, the two side wing pieces 121 are symmetrically arranged on the two outer sides of the cup part 11 to obtain a smooth, skin-fitting adjustable underwear.

[0049] When wearing the adjustable bra, first put on the bra normally, with the back surrounding part 12 arranged around the armpits and back of the human body, and connected with the back buckle part 13, and then put it on normally; then according to the breast shape requirements, press the inflatable part 242 to inflate the air cavity of the cup 113 and the air cavity of the lower strip 112, so that they expand and swell, specifically, the outer surface of the outer inflatable film layer 25 expands toward the cup part 11, so that the airbag component 2 plays a role in fixing and supporting the breasts and adjusting and modifying the breast shape.

[0050] After wearing and using, the air between the outer inflatable film layer 25 and the inner inflatable film layer 23 can be discharged to the outside by pressing the deflation piece 243, thereby deflating the airbag assembly 2. The airbag assembly 2 can be pressed by hand to assist in exhausting the air, and the adjustable underwear can be tidied up and stored for easy storage.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
