Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of tie-dye bags, and in particular relates to children's tie-dye bags. Background Technology
[0002] Tie-dyeing is an ancient and creative hand-dyeing technique. It involves physically resisting the dye on fabric through binding, folding, and pressing, followed by dyeing to create unique textures and patterns. To ensure children can safely experience this traditional craft, children's tie-dyeing uses non-toxic, easy-to-use dyes (such as food coloring or environmentally friendly dyes) and simplifies the steps, making it more suitable for children to participate in. Children's tie-dye bags are a fun and creative DIY craft project that allows children to experience the charm of color and art while playing, and also develops their hands-on skills and stimulates their imagination. However, it still has the following drawbacks in practical use:
[0003] During the tie-dyeing process, water is dripped directly onto the tie-dyeing bag. As the water passes over it, the pigment dissolves and seeps into the tie-dyeing fabric. As the work continues, the fabric is dyed. However, during the dyeing process, the pigment particles do not dissolve completely and seep out directly, which affects the uniformity of the tie-dyeing.
[0004] Secondly, during the tie-dyeing process, water droplets fall onto the tie-dye bag and quickly soak into the dye. However, after the dye is soaked, the water leaks onto the fabric. As the dye passes through the fabric, its solubility varies at different locations, resulting in insufficient dyeing. Utility Model Content
[0005] The purpose of this utility model is to provide a children's tie-dye bag. By setting up a lower plastic sheet, an upper plastic sheet, a pigment component, and a dispersion column, it solves the problem that incomplete dissolution of pigment particles during tie-dyeing will affect the tie-dye balance and the dyeing sufficiency is not high.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a children's tie-dye bag, comprising a lower plastic sheet, an upper plastic sheet, a pigment assembly, and a dispersion column. Both the lower and upper plastic sheets are arranged in arc-shaped cavities and are symmetrically positioned. A plastic ring is fixed to the top of the lower plastic sheet, and a plastic ring is fixed to the bottom of the upper plastic sheet. The plastic rings are welded together and fixed in place. A sealing ring is fixed to the inner wall of both plastic rings. The pigment assembly is fixed inside the sealing ring, and a dispersion column is fixed to the top of the pigment assembly. During operation, the lower plastic sheet contains the dyed pigment aqueous solution, while the upper plastic sheet contains the water used for tie-dyeing. As the water passes through the pigment assembly, it is dyed by the pigment column within the pigment assembly. The dispersion column evenly disperses the water before it passes through the pigment assembly.
[0008] Furthermore, an output plate is fixedly installed through the center of the bottom of the lower plastic sheet, and a water-permeable hole is fixedly installed vertically inside the output plate. A piece of gauze is fixed together on the inner wall of the lower plastic sheet at the bottom of the sealing ring and the top of the output plate. When the lower plastic sheet is working, the water-permeable hole on the output plate outputs the dyed water filtered by the gauze to the fabric that needs to be tie-dyed.
[0009] Furthermore, a second gauze is fixed to the inner wall of the upper plastic sheet. Both the second gauze and the upper plastic sheet are open at the top. A permeable mesh is fixed to the upper part of the opening of the upper plastic sheet, and water dripping onto the permeable mesh seeps into the upper plastic sheet.
[0010] Furthermore, the pigment assembly includes a pigment disk and cotton cloth, with the pigment disk being fixed together between two pieces of cotton cloth. The cotton cloth and the pigment disk are fixed together on the inner wall of the sealing ring. The pigment assembly fixes the pigment column within the pigment disk, and the cotton cloth at the top of the pigment disk filters impurities, while the cotton cloth at the bottom reduces leakage of undissolved pigment particles.
[0011] Furthermore, the pigment assembly also includes pigment columns. The pigment pan is made of plastic, and the pigment columns are uniformly and vertically fixed inside the pigment pan. The pigment pan fixes the pigment columns in the pan, and the pigment is dissolved by water after passing through the pigment columns.
[0012] Furthermore, the dispersion column is fixed to the top of the cotton cloth located at the top. The dispersion column is made of plastic and has vertically and uniformly distributed dispersion holes inside. When the dispersion column is working, water is dispersed into the cotton cloth located above through the dispersion holes.
[0013] This utility model has the following beneficial effects:
[0014] This invention solves the problem of incomplete dissolution of pigment particles affecting the uniformity of tie-dyeing by setting up a lower and upper plastic sheet. First, the fabric to be tie-dyed is tied up. Then, the output tray of the lower plastic sheet is placed on the fabric. Water droplets fall onto the permeable mesh on the upper plastic sheet, seep into the upper plastic sheet, and then through the pigment components. After being dyed, the water falls into the lower plastic sheet and is filtered through the gauze inside the lower plastic sheet before leaking onto the output tray. The water then seeps through the permeable holes on the output tray onto the dyed fabric, resulting in uniform dyeing.
[0015] This invention solves the problem of insufficient dyeing saturation in tie-dye bags by setting up an upper plastic sheet, pigment components, and a dispersion column. After water initially disperses and permeates through the permeable mesh on the upper plastic sheet, it falls onto the dispersion column and is dispersed through the dispersion holes on the column onto the cotton cloth located above. Excess water overflows from the top of the dispersion column and disperses onto the outer cotton cloth for further dispersion. It then permeates through the cotton cloth into the pigment column on the pigment tray, where the pigment dissolves in the water to form a pigment aqueous solution. After passing through the cotton cloth located below, it falls into the lower plastic sheet, resulting in higher dyeing saturation in the tie-dye bag. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0026] Please see Figure 1-4 This utility model is a children's tie-dye bag, including a lower plastic sheet 1, an upper plastic sheet 2, a pigment assembly 3, and a dispersing column 4. Both the lower plastic sheet 1 and the upper plastic sheet 2 are arranged in an arc-shaped cavity, and are symmetrically arranged. The lower plastic sheet 1 contains water that has permeated through the pigment column 302, while the upper plastic sheet 2 transports the water to the pigment assembly 3. A plastic ring 101 is fixed to the top of the lower plastic sheet 1, and a plastic ring 203 is fixed to the bottom of the upper plastic sheet 2. The plastic rings 101 and 203 are welded together to secure the upper plastic sheet 2. The upper plastic sheet 2 and the lower plastic sheet 1 are connected and fixed together, thus sealing the gap between the lower plastic sheet 1 and the upper plastic sheet 2. A sealing ring 102 is fixed on the inner wall of the first plastic ring 101 and the second plastic ring 203. The sealing ring 102 fixes the pigment component 3 in it. The pigment component 3 is fixed inside the sealing ring 102. When water passes through, the pigment component 3 dyes the water as it seeps through. A dispersing column 4 is fixed on the top of the pigment component 3. The dispersing column 4 disperses the water that passes through, preventing the water from concentrating in the center of the pigment component 3 and ensuring the uniformity of the pigment that seeps through.
[0027] Specifically, an output plate 104 is fixed through the center of the bottom of the lower plastic sheet 1. A water-permeable hole 105 is fixed vertically through the output plate 104. A gauze 103 is fixed together with the inner wall of the lower plastic sheet 1 at the bottom of the sealing ring 102 and the top of the output plate 104. When the lower plastic sheet 1 is working, the gauze 103 reduces the output of undissolved pigment from the water-permeable hole 105 on the output plate 104. Water dyed with pigment permeates through the water-permeable hole 105 on the output plate 104.
[0028] Furthermore, a second gauze 201 is fixed on the inner wall of the upper plastic sheet 2. Both the second gauze 201 and the upper part of the upper plastic sheet 2 are open. A water-permeable net 202 is fixed in the upper part of the opening of the upper plastic sheet 2. The second gauze 201 inside the upper plastic sheet 2 allows water to seep in. The water-permeable net 202 allows water to enter the upper plastic sheet 2 when dripping.
[0029] The operation process of this embodiment is as follows: In the operation, the fabric to be tie-dyed is first tied up, and the output tray 104 of the lower plastic sheet 1 is placed on the fabric to be tie-dyed. Water droplets fall onto the water-permeable mesh 202 on the upper plastic sheet 2, seep into the upper plastic sheet 2 through the water-permeable mesh 202, and then seep through the pigment component 3. After being dyed, the water drops into the lower plastic sheet 1 and is filtered through the gauze 103 in the lower plastic sheet 1 before leaking onto the output tray 104. The water then seeps out through the water-permeable holes 105 on the output tray 104 onto the dyed fabric for uniform dyeing. Specific Implementation Example 2
[0030] Please see Figure 1 , 4 5, 6. Based on the specific embodiment 1, the pigment assembly 3 includes a pigment tray 301 and a cotton cloth 303. The pigment tray 301 is fixed between the two cotton cloths 303. The cotton cloth 303 and the pigment tray 301 are fixed together on the inner wall of the sealing ring 102. When the pigment assembly 3 is working, when water flows to the pigment tray 301, it soaks the pigment column 302, and the water with pigment falls onto the lower plastic cloth 1.
[0031] Specifically, the pigment assembly 3 also includes pigment columns 302, the pigment tray 301 is made of plastic, and the pigment columns 302 are uniformly and vertically fixed inside the pigment tray 301. The pigment columns 302 on the pigment tray 301 provide the pigment for dyeing.
[0032] Furthermore, the dispersion column 4 is fixed to the top of the cotton cloth 303 located at the top. The dispersion column 4 is made of plastic, and the dispersion column 4 has vertically and uniformly opened dispersion holes 401. When the dispersion column 4 is working, when water falls onto the dispersion column 4, it is dispersed into the cotton cloth 303 through the dispersion holes 401 on the dispersion column 4. Excess water falls from the periphery onto the cotton cloth 303 located above at the top of the dispersion column 4.
[0033] The operation process of this embodiment is as follows: During operation, when water is initially dispersed and permeated through the permeable mesh 202 on the upper plastic sheet 2, it falls onto the dispersion column 4 and is dispersed through the dispersion holes 401 on the dispersion column 4 onto the cotton cloth 303 located above. Excess water spreads out at the top of the dispersion column 4 and falls onto the cotton cloth 303 on the outside of the dispersion column 4 for further dispersion. Then, it permeates through the cotton cloth 303 into the pigment column 302 on the pigment tray 301, and the pigment in the pigment column 302 dissolves in the water to form a pigment aqueous solution. After passing through the cotton cloth 303 located below, it falls into the lower plastic sheet 1.
