Summary of the Invention

Problems to be Solved by the Invention

[0004] There has been a demand for a cylinder for a respirator that can be manufactured with a simpler process.

Means for Solving the Problems

[0005] The cylinder for a respirator according to this invention includes a label that extends in the longitudinal direction and is provided on the cylinder for the respirator. The label has a first region and a second region, and the same information regarding the cylinder is displayed in the first region and the second region. The information includes at least any one of the serial number of the cylinder, the manufacturing date of the cylinder, and the maximum operating pressure of the cylinder. One of the first region and the second region is painted and the other is exposed from the painting and is visible.

[0006] A method for manufacturing the above-described cylinder for a respirator, the method including a step of attaching the label to a predetermined position of the cylinder, and a step of painting a part of the cylinder and the label so that one of the first region and the second region is painted and the other is exposed from the painting and is visible.

[0007] Preferably, the step of attaching the label includes the step of attaching the label based on the position of the hanging device during painting. [Brief explanation of the drawing]

[0008] [Figure 1] This is a photograph showing label 100, which is affixed to a gas cylinder. [Figure 2] This is a photograph showing cylinder 201 with label 100 attached, as shown in Figure 1. [Figure 3] This diagram shows a hanging device 401 used when painting cylinder 201, and a label positioned relative to the hanging device 401. [Figure 4] This is a photograph of cylinder 201 with a painted label 100. [Modes for carrying out the invention]

[0009] Figure 1 is a photograph showing a label 100 to be affixed to a cylinder. As shown in Figure 1, the label 100 according to the present invention has a first region 101 and a second region 102. The same information is displayed in the first region 101 and the second region 102. The information displayed in the first region 101 and the second region is shown in Table 1.

[0010] [Table 1]

[0011] "AIR WATER AIR" indicates that the type of high-pressure gas that Air Water Disaster Prevention Co., Ltd. can manufacture and fill containers with is air.

[0012] "730CIII" indicates that the container's name is 730CIII. "V6.8" indicates that the container has an internal volume of 6.8L.

[0013] "TP49.0M FP29.4M AL" indicates that the pressure in the pressure resistance test is 49.0 MPa, the maximum filling pressure is 29.4 MPa, and the material used for the container is an aluminum alloy.

[0014] "DC 0.84 DD 0.41" indicates that the acceptable scratch depth for the fiber-reinforced plastic part of the body is 0.84 mm, and the acceptable scratch depth for the fiber-reinforced plastic parts other than the body is 0.41 mm.

[0015] Figure 2 is a photograph showing cylinder 201 with label 100 attached, as shown in Figure 1. As shown in Figure 2, a valve 202 is attached to cylinder 201 (container). Gas (air in this example) is supplied from valve 202 to facepiece 300.

[0016] In Figure 2, cylinder 201 is unpainted, and the first region 101 and second region 102 of label 100 are exposed.

[0017] Cylinder 201 may be made of metal or FRP. FRP stands for "Fiber Reinforced Plastics." Plastic or metal cylinder 201 may be reinforced with other materials.

[0018] The cylinder 201 is attached to a backpack. Various parts are attached to the backpack, and the presence of these parts may make it impossible or difficult to read the contents of label 100 on cylinder 201. Therefore, by attaching the label to a part of the circumference of cylinder 201 in a position that is easily readable when cylinder 201 is set on the backpack, it is possible to make the contents of label 100 easier to read from the outside.

[0019] FIG. 3 is a view showing a hanging tool 401 used when painting the cylinder 201 and a label positioned based on the hanging tool 401. When painting the cylinder 201, the hanging tool 401 is screwed into the screw hole for attaching the valve 202, and the hanging tool 401 and the cylinder 201 are hung on a jig and painted. Before painting, a label 100 is attached to the cylinder 201. At this time, the label 100 is attached based on the hanging tool 401 and a line 402 extending from the hanging tool 401. Then, by painting the label 100 and the cylinder 201, a part of the label 100 is painted while another part of the label 100 is exposed.

[0020] When setting the cylinder 201 on the breathing apparatus using the cylinder hanging tool 401 (a jig for hanging the cylinder during spray painting) aligned with the screw cutting position of the valve, the position of the label 100 is specified so that the label 100 can be read from the side.

[0021] FIG. 4 is a photograph of the cylinder 201 having the painted label 100. In the label 100, the painted part is indicated by a two-dot chain line. The non-painted part (the first region 101) of the label 100 is exposed, and the user can visually recognize the content of the label 100. On the other hand, the user cannot visually recognize the painted part of the label 100.

[0022] That is, for example, the label 100 described on the cylinder 201 made of FRP cannot determine the attachment position on the circumference of the cylinder based on the valve because it is attached to the cylinder 201 before installing the valve 202 to be attached to the cylinder 201 by a normal manufacturing method. Therefore, depending on the positional relationship, the label 100 may become invisible when the cylinder 201 is attached to the breathing apparatus. Since information such as a management number and a use pressure is described on the label 100, it is necessary to remove the cylinder 201 from the breathing apparatus once for confirmation, increasing the management effort.

[0023] To solve these problems, a label 100 with the same content on multiple sides (first region 101 and second region 102) is attached to the cylinder 201. During the painting stage, the position on the circumference of the cylinder 201 is determined by a hanging device 401 used during painting. Of the multiple regions, the effective ones are left and the rest are covered by painting.

[0024] This ensures that the position of the label 100 on the circumference of the cylinder 201 remains constant relative to the valve 202. The label 100 is always positioned in a visible location when attached to a self-contained breathing apparatus.

[0025] By increasing the area of ​​the wrap-around label, more than half of the gray area (which is required by law to be painted gray) can be covered, reducing (or eliminating the need for) painting.

[0026] In other words, the respiratory cylinder 201 is provided with a longitudinally extending label 100 on the cylinder 201. The label 100 has a first region 101 and a second region 102, both of which display the same information about the cylinder 201, including at least one of the serial number of the cylinder 201, the date of manufacture of the cylinder 201, and the maximum operating pressure of the cylinder. One of the first region 101 and the second region 102 is painted, while the other is exposed and visible from the paint.

[0027] The above-described method for manufacturing a respiratory cylinder 201 comprises the steps of: attaching a label 100 to a predetermined position on the cylinder 201; and painting a portion of the cylinder 201 and the label 100 such that one of the first region 101 and the second region 102 is painted, while the other is exposed from the paint and visible. By using a label 100 that extends in the longitudinal direction and painting a portion of the label 100, the label 100 adheres more easily to the cylinder 201.

[0028] The process of attaching label 100 includes attaching label 100 based on the position of the hanging device 401 during painting. This makes it possible to attach label 100 in a visible location when the gas cylinder 201 is attached to the backpack.

[0029] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the embodiments described above, and all modifications within the meaning and scope of the claims are intended to be included.
