Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a cartridge for a wire drawing device, and more specifically, it can be used by simply attaching it to the wire drawing tool itself and the handle, and therefore does not contaminate hands and surroundings. The present invention relates to a cartridge for a wire drawing device that is compact and easy to transport and store.

"Prior Art and Problems" Traditionally, line drawing tools for drawing lines on stadiums, etc., have a hollow body with a handle attached to the top of the wheel, which is filled with powder such as slaked lime or calcium carbonate by hand or with a shovel. It is available for use. In this case, slaked lime and calcium carbonate are fine powders that are scattered into the atmosphere during filling, and not only enter the filling worker's eyes and trachea, but also pollute the surrounding area, and also come into direct contact with the skin of hands and feet. Slaked lime causes various harmful effects such as rough skin. Furthermore, although conventional wire drawing tools have lids, they are not airtight, and if they are tipped over, powder may come out, making them inconvenient to transport. Dirt,
It is extremely difficult to transport without such contamination. This also applies to the case of transporting spare powder. Furthermore, slaked lime has excellent hygroscopicity, and when it absorbs moisture, it becomes lumpy and becomes a hindrance to wire drawing work, but conventional wire drawing tools are not airtight.
The remaining powder must be transferred to another airtight container after use, which is extremely troublesome.

Further, in the conventional wire drawing tool, the main body and the handle of the wire drawing tool are constructed as an inseparable unit, which causes various inconveniences in handling, storage, etc. For example, when attaching a cartridge to the wire drawing tool body,
It is preferable to open the lid of the cartridge, insert the wire drawing tool body into the opening upside down, and then return it to its original state in order to prevent powder from flying up, escaping into the surrounding area, and contaminating it. However, if the wire drawing tool main body and the handle are inseparable, the weight is large and the handle gets in the way, making it extremely difficult to perform the above operations smoothly. Also, after completing the line drawing work,
When storing the powder remaining in the drawing tool main body in a cartridge, the above-mentioned operation is reversed, but the same problem occurs in this case as well.

Furthermore, when drawing colored lines using three types of powder, for example white, yellow, and red, if you try to replace the powder into the drawing tool, the colors will mix immediately after replacing the powder, and the mixed powder during this time will be mixed. I have no choice but to throw it away.

In order to avoid this trouble, three devices have to be prepared, but since the conventional wire drawing tools have a wire drawing tool body and handle that are inseparable, they are not only expensive, but also difficult to transport and store. In some cases, a large amount of space is required.

"Means for Solving the Problems" In view of the above-mentioned problems, the present invention was devised as a result of intensive research to eliminate the above-mentioned drawbacks.

That is, the present invention is a cartridge for a wire drawing device, in which a powder is filled in a container having an opening and a lid at both ends, and a handle attachment part is provided on the outside of the side wall of the container. be.

There are no particular restrictions on the material used for the container of the present invention, and plastic, paper, wood, metal, glass, etc. can be used, but plastic or a combination of paper and plastic (laminated ) is advantageous. The shape of the cartridge is not particularly limited and may be cylindrical or prismatic, but a cylindrical shape is preferred from the viewpoint of powder discharge performance and stability of the cartridge.

In the present invention, openings are provided at both ends of the container, one opening is for attaching to the wire drawing tool body, and the other opening is for functioning as an air vent hole during the wire drawing operation. It is something. Therefore, the latter opening may be small, with a diameter or side of several millimeters to several centimeters. However, although it is not necessarily the intention of the present invention, if the cartridge is made slightly larger, for example, when a replacement cartridge is not prepared,
There is an advantage that powder can be additionally filled through the opening. In addition to the opening, an air vent hole may be provided in the vicinity of the opening, for example, in the neck portion.

The lid body is removably attached to the opening by screwing, concave-convex fitting, crimping, or the like.

One of the openings mainly functions as an air vent hole as described above, but the opening has a lid attachment part with a male or female screw carved into it that protrudes from the container. The attachment part is provided with a through hole, and the lid body is provided with a female thread or a male screw that is screwed into the lid attachment part, and a through hole, and when the lid body is tightened, the two through holes do not communicate, and when the lid body is tightened, the two through holes do not communicate with each other. If the structure is such that both through-holes overlap and communicate with each other to form an air vent hole when tightening, the air vent hole can be formed without removing the lid from the container, eliminating the problem of losing the lid, and also eliminating wires. Once the pulling operation is completed, the remaining powder can be stored in a hermetically sealed state by simply tightening the lid.

In the present invention, a handle attachment part is provided on the outside of the side wall of the container.

"Example" Next, the present invention will be described based on drawings showing embodiments of the present invention.

1A and 1B show an embodiment of the cartridge of the present invention, FIG. 1A is an exploded view, and FIG. 1B is an assembled view. In the figure, the cartridge of the present invention stores powder (not shown) in a container 3 having openings 1, 1' and lids 2, 2' at both upper and lower ends. The openings 1, 1' are provided with a protruding lid mounting portion 4,
4', the lid mounting portion is provided with a male screw,
Further, a through hole 5 is formed in one lid mounting portion 4'. The lids 2 and 2' are each provided with a female thread so as to be screwed into the lid mounting portions 4 and 4', and one of the lids 2' is provided with a through hole 6. The relationship between the through hole 6 of the lid body 2' and the through hole 5 of the lid body attachment part 4' is that when the lid body 2' is tightened onto the lid body attachment part 4', both the through holes 5 and 6 are properly closed. The positional relationship is such that when the lid body 2' is appropriately relaxed, the through holes 5 and 6 overlap and communicate with each other to form an air hole. Therefore, in order to facilitate the overlapping of both the through holes 5 and 6, it is a preferable embodiment that the through holes are horizontally elongated or oval.

Handle attachment portions 7, 7' are provided on the outside of the side wall of the cartridge container 3. The handle attachment parts 7, 7' may be integrally molded of the same material as the container 3, or may be made of the same or different material from the container and attached by adhesive, welding, or mechanical attachment means such as bolts and nuts. good.
