Embodiment 2

[0112] The drug injection cartridge may include a second anti-slip part (120).

[0113] The structure other than the second anti-slip part (120) is the same as the above description, so the relevant description is omitted.

[0114] Such as Figure 10 to Figure 13 As shown, the second anti-slip part (120) may be formed on one side of the cartridge case (30) so as to be connected to the surface of the rubber mold (30) formed on the side of the cartridge part (20).

[0115] The second anti-slip part (120) may be made of the same material as the cartridge housing (30). Preferably, it may be manufactured from polyethylene or polypropylene.

[0116] Such as Figure 12 As shown, the second anti-slip part (120) is formed extending along the length direction of the second protective part (32) formed on one side of the cartridge housing (30), and forms a short protrusion along the direction of the second space part (33) The way the table stands out is formed.

[0117] In addition, ...
