Description

[Detailed description of the invention] [Field of the invention] The invention relates to an improvement of a line drawing device that draws lines by discharging line materials such as lime powder, and is not particularly bulky and can be stored and stored in warehouses etc. The present invention relates to a line drawing device that is easy to transport by hand or by car.

[Technical background of the invention] In sports competitions held outdoors, the field is set by drawing lines using a line drawing device containing line material such as lime powder.
Line materials such as lime are usually packed in bags.
The line material had to be transferred to a line drawing device for use, and the line material sometimes scattered or generated dust during transfer. Then, there was a problem that it could be inhaled or injected into the eyes, which could have an adverse effect on the human body. In addition, line drawing devices are generally made of metal and are heavy.
There are also problems in that it takes up a lot of space when cleaning up afterwards, and it is difficult to handle, so it has been desired to reduce the weight and simplify the structure.

In order to solve this problem, a container containing line material in advance and a line material discharging device for discharging the line material are configured separately, and the line material container is inserted into the line material discharging device,
A proposal has been made for a line drawing device that pierces a part of the line material container during insertion using a protrusion provided inside the line material discharge device, and discharges the line material that is the contents of the line material container from the line material discharge device. (Utility Model Application Publication No. 60-192863).

This line drawing device consists of a separate container containing line material and a line material discharge device for discharging the line material. After the line material in the container is used up, the line material is discharged. Since only the device can be stored, it is lightweight, does not take up much storage space, and is easy to handle. If it is to be used again later, a new line material container is inserted into the discharge device.

However, when using this line drawing device, the joint between the line material discharger and the line material container is designed to be tightly sealed to prevent line material from leaking, and the line material container is There is a problem in that it is difficult to insert into the line material discharge device. Therefore, in order to insert the line material container into the line material discharging device, it is necessary to push it in with force, which results in forceful insertion, and at that time, the line material discharging device and the line material container There is a problem in that the line material may spray out from the joint or the discharge hole of the line material and may be inhaled or put into the eyes.
Furthermore, because this line drawing device has a short seam with the line material discharge device, if the line material container is made of paper, it will adhere tightly at first, but as it is used, the seam will loosen. There is also the problem that the line material container is easily removed from the line material discharge device.

As a line drawing device composed of a line material discharge device and a line material container, a proposal has also been made in which the line material discharge device is inserted by tearing through the line material container to discharge the line material (Jitsukai Sho. 59-33471). However, this line drawing device also requires force to be pushed in order to insert the line material discharge device into the line material container, and there is a problem that the line material may spout out when the line material container is pierced. be. Furthermore, this line drawing device is used by inserting the line material discharge device into the line material container, but as it is used, the seam between the line material container and the line material discharge device becomes loose, and the line material is removed from the line material container. There is also the problem that the material ejector may fall out or line material may spill out of the seams.

In order to prevent the line material from scattering or spouting out, a line pulling device has been proposed in which a container containing the line material is opened and then stored inside the container (Japanese Utility Model Publication No. 12837/1983). This line drawing device accommodates the line material container in the line drawing device by holding the opening of the line material container in order to attach the container containing the line material to the line drawing device.
The line material container must be fixed to the line drawing device at both edges of the opening, and the line material container is heavy and requires time and effort to attach. This line drawing device requires not only a line material discharging device but also a container portion for accommodating the line material container, which increases manufacturing costs.

[Purpose of the invention] The present invention provides a line drawing device that can safely and easily attach a line material container to a line material discharge device without scattering or spouting the line material, and that can be manufactured at low cost. The purpose is to submit.
