Abstract
Description
Technical Field
[0001] This utility model relates to the field of laundry bag technology, specifically to a double-winged laundry bag suitable for underwear and bras. Background Technology
[0002] A laundry bag is a bag used to protect clothes when machine washing. It is made of a breathable, microporous material. You put delicate items like underwear, sweaters, or other items that are prone to deformation inside, zip it up, and then put it in the washing machine. Bags made of mesh nylon (similar to the material of mosquito nets) are used for drying sweaters and for separating clothes when washing underwear to prevent staining and damage.
[0003] However, existing laundry bags are generally made of very simple mesh belts. After underwear and bras are put into them, the large number of underwear and bras inside the laundry bag are still easily deformed or damaged due to friction and pulling. In particular, the metal hooks of the bras may damage other clothes in the laundry bag or the bras themselves, resulting in poor protection for underwear and bras, which needs to be improved. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a double-winged laundry bag suitable for underwear and bras, which can provide more effective protection for underwear or bras when they are put into the laundry bag and put into the washing machine.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:
[0006] A double-wing laundry bag suitable for underwear and bras includes a bag body, binding fabric, elastic bands, and a zipper. The bag body is a rectangular piece of fabric with rounded corners at the top and bottom, folded in half along the center line. The elastic bands are set along the fold line and are sewn to the bag body at both ends. Binding fabric is sewn to opposite sides of the bag body. The two binding fabrics are connected by a zipper, and the laundry bag closes when the zipper is closed.
[0007] Both the main body of the bag and the edging fabric are made of water-permeable material. This makes it easy to hang the bag on a drying line or similar surface for drying.
[0008] As an improvement, hanging straps are sewn to both ends of the bag body, and the two hanging straps are connected by snap fasteners. This makes it easy to hang the bag on a drying line.
[0009] As an improvement, a carrying handle is sewn onto the middle side of the bag body, making it easier to carry.
[0010] As an improvement, an elastic zipper tape is sewn between one end of the two binding fabrics. When the zipper is closed, the zipper pull is hidden and secured by the elastic zipper tape. This prevents the zipper pull from shifting position after the zipper is tightened, thus making it less likely for the zipper to open automatically.
[0011] The advantages of this utility model compared with the prior art are as follows:
[0012] When using this new type of garment, the underwear / bra is placed inside the laundry bag. This effectively protects the underwear / bra during the washing machine process, reducing friction and stretching deformation with other clothes. Through the design of the elastic pressure band and its cooperation with the bag body, the underwear / bra can be effectively positioned and restrained, thus preventing the underwear / bra from shifting or going off-center during washing. It can also effectively prevent damage to the bra from the bra strap metal / bra hooks. Attached Figure Description

[0019] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.
[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] A double-wing laundry bag suitable for underwear and bras includes a bag body 1, binding fabric 2, elastic bands 3, and a zipper 4. The bag body 1 is a rectangular fabric with rounded corners at the top and bottom, folded in half along the center line. The elastic bands 3 are positioned along the fold line and sewn to the bag body 1 at both ends. Binding fabric 2 is sewn onto opposite sides of the bag body 1, and the two binding fabrics 2 are connected by a zipper 4. When the zipper 4 is closed, the laundry bag is shut. Both the bag body 1 and the binding fabric 2 are made of water-permeable fabric, such as sandwich mesh fabric.
[0022] The two ends of the bag body 1 are each sewn with a hanging strap 5, and the two hanging straps 5 are connected by a snap fastener 6. A handle 7 is also sewn to the side of the middle part of the bag body 1. An elastic zipper tape 8 is sewn between one end of the two binding fabrics 2. When the zipper 3 is closed, the zipper is hidden and fixed by the elastic zipper tape 8.
[0023] In the specific implementation of this embodiment:
[0024] Place the bra or lingerie into the laundry bag. The two folded parts of the bag body 1 act as securing wings. The bra or lingerie passes between the elastic band 3 and the bag body 1. When the zipper 4 is closed, the center of the bra or lingerie is compressed and secured by the elastic band 3, while the remaining parts are restrained and positioned by the wings, forming a three-point restraint and positioning system. Then it can be placed in the washing machine for washing. The bra or lingerie is less likely to shift during the washing process. After washing, it can be hung to dry directly using the hanging strap 5 or the handle 7.
[0025] This design utilizes a double-wing, arc-shaped, three-dimensional structure to better fit the shape of the bra. The double wings and the central fixing strap provide three-point fixation, preventing the bra from shifting during washing machine operation and ensuring each part is isolated. In addition to the internal structure, the outer button-type fixing straps allow for direct attachment to a hanger for drying, or hanging by hand.
[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
