Description

Technical Field

[0001] This invention relates to the field of marking chalk on clothing, and in particular to a chalk that dispenses chalk by pressing the end of the pen. Background Technology

[0002] In the assembly line garment manufacturing process, different processes require different employees. Therefore, marking with chalk is an important step that allows for the pre-marking of the cutting or sewing positions of the fabric, facilitating standardized work by employees.

[0003] Most existing chalks use plaster or wax-based chalk sheets or low-temperature or high-temperature fading pens similar to oil-based pens. However, all of these types of chalks have problems when used. Plaster or wax-based chalk sheets require careful fabric cleaning. While low-temperature or high-temperature fading pens do not require cleaning, they do require low-temperature or high-temperature treatment to fade the lines on the fabric. When products marked with low-temperature fading pens are sold to areas with higher temperatures, or products marked with high-temperature fading pens are sold to areas with lower temperatures, the lines will reappear, affecting the product's appearance and quality.

[0004] Therefore, existing chalk has the problems of cumbersome mark removal and easy recurrence of marks. Summary of the Invention

[0005] The purpose of this invention is to provide a chalk that dispenses powder by pressing the end of the pen. This invention not only allows for easier removal of markings but also has the advantage that the drawn lines will not reappear.

[0006] The technical solution of this invention: A chalk pen with a press-to-dispense tail, comprising a hollow pen barrel with openings at both ends, and a limiting step at the bottom of the pen barrel that tapers inward; a storage rod with openings at both ends and a hollow interior is slidably disposed inside the pen barrel, the storage rod being filled with colored marking powder; a boss-shaped pen cap is sleeved on the top of the storage rod, the bottom of the pen cap is slidably disposed inside the pen barrel, and a limiting sleeve threadedly connected to the top of the pen barrel is fitted above the bottom of the pen cap, the top of the pen cap slidingly extending above the limiting sleeve; a feeding rod is fixedly connected to the bottom of the storage rod, and the feeding rod has an axially arranged and connected storage rod... The feed rod has a hollow, interconnected powder outlet. The bottom of the feed rod is integrally equipped with a multi-lobed elastic claw. A locking sleeve with its bottom end in contact with a limiting step is slidably sleeved on the elastic claw. A return spring is sleeved on the outside of the feed rod between the locking sleeve and the bottom of the feed rod. By pressing down on the top of the pen cap, the feed rod and the feed rod move downward relative to the pen. The return spring between the locking sleeve and the feed rod is compressed, and the elastic claw extends downward and opens from the middle of the locking sleeve and the limiting step. The colored marking powder inside the feed rod will fall downward along the powder outlet and the middle of the opened elastic claw under the action of gravity.

[0007] In the aforementioned chalk with a press-to-dispense tail, the marking powder is baby powder or cornstarch.

[0008] In the aforementioned chalk with a press-to-dispense tail, a hollow pen tip is threadedly connected at the bottom end of the pen barrel below the limiting step, and the bottom of the pen tip has an opening.

[0009] In the aforementioned chalk with a press-to-dispense tail, the bottom of the pen tip has multiple notches arranged in a ring at intervals at the position corresponding to the edge of the opening.

[0010] In the aforementioned chalk with a press-to-dispense tail, a magnet is fixedly connected to the side of the pen barrel.

[0011] In the aforementioned chalk with a press-to-dispense tail, a recessed mounting groove is provided on the pen barrel at the position corresponding to the magnet, and the magnet is embedded and fixed in the mounting groove.

[0012] In the aforementioned chalk with a press-to-dispense tail, a flexible rope is connected to one side of the limiting sleeve.

[0013] In the aforementioned chalk with a press-to-dispense tail, the diameter of the storage rod is 5-20 mm; the wall thickness of the storage rod is 1 mm.

[0014] In the aforementioned chalk with a press-to-dispense tail, the diameter of the opening is 3-10 mm.

[0015] Compared with existing technologies, this invention performs the marking operation by sprinkling colored marking powder onto the fabric. The marking powder can then be removed simply by shaking and patting, making the removal process convenient and eliminating the problem of marking recurrence. The colored marking powder is stored in a storage rod. When not in use, the top of the storage rod is sealed by a pen cap, and a feeding rod is fixed to the bottom. The multi-lobed elastic claws at the bottom of the feeding rod are closed and sealed by a locking sleeve, preventing the marking powder from becoming damp and clumping. When the storage rod moves downwards relative to the pen, the elastic claws extend and open from the locking sleeve and the limiting step, allowing the marking powder in the storage rod to fall onto the fabric through the powder outlet and the open elastic claws, thus achieving the marking effect. The operation is simple. After opening the pen cap, marking powder can be replenished into the storage rod, improving durability.

[0016] In addition, the marking powder used in this invention is baby powder or corn starch, which can mark the powder without easily irritating the human body and has a high safety profile.

[0017] A hollow pen tip is threadedly connected to the bottom of the pen barrel below the limiting step, and the bottom of the pen tip has an opening. This allows the elastic claws extending downwards from the middle of the limiting step to open inside the pen tip. When marking, the marking powder passes through the opening of the pen tip before contacting the fabric surface. During this process, the open elastic claws do not directly contact the fabric, avoiding damage and improving durability. Multiple annularly spaced notches at the opening prevent the bottom opening of the pen tip from sealing against the fabric, allowing the marking powder inside the pen tip to fall more effectively.

[0018] With a magnet fixed to the side of the pen barrel, users can easily attach the chalk to the iron side of the sewing table for convenient storage; and the magnet is glued and embedded in the mounting groove of the pen barrel without protrusion, improving the comfort of use.

[0019] By attaching a flexible rope loop to one side of the limiting sleeve, it is convenient to hang and place the chalk. The rope loop can also be put on the user's thumb to reduce the problem of chalk being lost due to the user's careless placement.

[0020] By making the diameter of the storage rod 5-20mm, the wall thickness of the storage rod 1mm, and the diameter of the opening 3-10mm, the marking powder falls more smoothly.

[0021] Therefore, this invention not only makes it easier to remove markings, but also has the advantages of preventing the markings from reappearing, being easy to operate, having good durability, high security, being easy to place and store, and being less likely to be lost.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0025] Example. A chalk that dispenses powder by pressing the end, comprising as follows: Figure 1 and 2As shown, the device includes a pen barrel 1 with openings at both ends and a hollow interior. The bottom of the pen barrel 1 has an inwardly tapering limiting step 2. A storage rod 3, also with openings at both ends and a hollow interior, is slidably disposed inside the pen barrel 1. The storage rod 3 is filled with colored marking powder. A boss-shaped pen cap 4 is sleeved on the top of the storage rod 3. The bottom of the pen cap 4 is slidably disposed inside the pen barrel 1. A limiting sleeve 5, threadedly connected to the top of the pen barrel 1, is fitted above the bottom of the pen cap 4. The top of the pen cap 4 slides out above the limiting sleeve 5. A feeding rod 6 is fixedly connected to the bottom of the storage rod 3. The feeding rod 6 has an axially arranged powder outlet 7 that communicates with the hollow interior of the storage rod 3. The bottom end of the feeding rod 6 is integrally provided with a multi-lobed elastic claw 8; a locking sleeve 9 with its bottom end in contact with the limiting step 2 is slidably sleeved on the elastic claw 8; a return spring 10 sleeved on the outside of the feeding rod 6 is provided between the locking sleeve 9 and the bottom end of the storage rod 3; by pressing down the top of the pen cap 4, the storage rod 3 and the feeding rod 6 move downward relative to the pen 1, the return spring 10 between the locking sleeve 9 and the storage rod 3 is compressed, the elastic claw 8 extends downward from the middle of the locking sleeve 9 and the limiting step 2 and opens, and the colored marking powder in the storage rod 3 will fall downward along the powder outlet 7 and the middle of the opened elastic claw 8 under the action of gravity.

[0026] The labeling powder is baby powder or cornstarch.

[0027] The pen barrel 1 is threadedly connected to a hollow pen tip 11 at the position below the limiting step 2 at the bottom end, and the pen tip 11 has an opening 12 at the bottom; the pen tip 11 has multiple notches 16 distributed in a ring at intervals at the position of the bottom of the opening 12.

[0028] A magnet 13 is fixedly connected to the side of the pen barrel 1; a recessed mounting groove 14 is provided on the pen barrel 1 at the position corresponding to the magnet 13, and the magnet 13 is embedded and fixed in the mounting groove 14.

[0029] A flexible rope loop 15 is connected to one side of the limiting sleeve 5.

[0030] The diameter of the storage rod 3 is 5-20 mm; the wall thickness of the storage rod 3 is 1 mm.

[0031] The diameter of the opening 12 is 3 to 10 mm.

[0032] Working principle: When you need to mark the fabric with chalk, simply hold the pen barrel 1 with your hand, align the bottom opening 12 of the pen tip 11 with the position on the fabric where you want to mark the fabric with chalk, then press down on the pen cap 4 with your thumb and move the pen barrel 1 while shaking it. It is easy to use.

[0033] When the pen cap 4 is pressed down, the top of the pen cap 4 moves toward the limiting sleeve 5, and the bottom of the pen cap 4 slides inside the pen barrel 1, causing the bottom end of the storage rod 3 to compress the reset spring 10 toward the locking sleeve 9. At this time, the feeding rod 6 and the elastic claw 8 fixed at the bottom end of the storage rod 3 move downward, and the elastic claw 8 extends out of the locking sleeve 9 and the middle of the limiting step 2 and opens inside the pen head 11. Under the action of gravity and the shaking action of the pen barrel 1, the colored marking powder in the storage rod 3 falls out through the powder outlet 7 from the opened elastic claw 8 into the pen head 11, and falls onto the fabric from the opening 12 at the bottom of the pen head 11 (because the opening 12 is provided with multiple annularly spaced notches 16, the opening 12 at the bottom of the pen head will not be sealed and adhered to the fabric, so that the marking powder in the pen head 11 can fall better). After the powder is applied, the user can invert the pen barrel 1 and lift the thumb that pressed the pen cap 4. At this time, the compressed return spring 10 will push the storage rod 3 toward the pen cap 4 to reset. The pen cap 4 can also be pushed to its bottom to contact the limit sleeve 5. The feeding rod 6 and the elastic claw 8 can also move synchronously with the storage rod 3. The elastic claw 8 can retract into the locking sleeve 9 to achieve closure.

[0034] When the marking powder needs to be replenished, simply unscrew the limiting sleeve 5 from the top of the pen barrel 1 and remove it, then pull the pen cap 4 out from the top of the storage rod 3. Then you can replenish the marking powder from the opening at the top of the storage rod 3, allowing the chalk to be used for a long time.

[0035] When using the chalk, the user can put the rope loop 15 on one side of the limiting sleeve 5 on the thumb to avoid losing the chalk when it is placed carelessly. When the user leaves work, the user can hang the rope loop 15 in a specific position or attach it to a sewing machine or other iron object by using the magnet 13 in the mounting groove 14 on the side of the pen barrel 1. This makes it easy to store and put away the chalk.
