As shown in FIGS. 1 and 2, the packaging assembly 1 includes a liquid injection tool 5 and a packaging body 2 that houses the liquid injection tool 5.

The liquid injector 5 is an auto-injector that has a long shape and is pre-filled with a chemical solution (liquid), and is used when the chemical solution is injected (administered) into a living body. The drug solution is not particularly limited and is appropriately selected depending on the purpose of use, and examples thereof include hematopoietic agents, vaccines, hormone preparations, anti-rheumatic agents, anti-cancer agents, anesthetics, anticoagulants and the like. Can be mentioned.

As shown in FIGS. 2 to 5, the liquid injector 5 includes a liquid injector body (main body portion) 6 having a long shape, and a cap 7 detachably attached to the liquid injector body 6. ing. By attaching the cap 7 to the liquid injection tool body 6, a needle 66 described later of the liquid injection tool body 6 can be protected, and erroneous puncture by the needle 66 can be prevented.

The liquid injection tool body 6 includes a housing 63 having a bottomed cylindrical shape, a syringe 61 disposed on the inner peripheral side of the housing, a syringe holder 62 for holding the syringe 61, and at least a distal end of a needle 66 described later of the syringe 61. A needle cover 64 covering the portion, a first coil spring (not shown), and a second coil spring (not shown). The syringe holder 62 is held by the housing 63. The housing 63 covers a portion other than the needle 66 of the syringe 61, that is, the cylindrical body 611. The housing 63 is also a grip portion that is gripped when injecting a chemical solution into a living body. The housing 63 only needs to cover at least the base end portion of the syringe 61.

The syringe 61 has a cylindrical shape with a bottom and can be filled with a chemical solution, a needle (hollow needle) 66 that is attached to the tip of the cylindrical body 611 and discharges the chemical solution, and is provided in the cylindrical body 611. And a gasket 67 that can slide within the cylindrical body 611 and a pusher (not shown) connected to the gasket 67. The first coil spring urges the gasket 67 in the distal direction through the pusher.
