Abstract: A safety mechanism syringe includes a syringe, a needle, a holder, and a needle cover displaceable relatively with respect to the syringe along an axial direction of the syringe from a use position toward a protection position. The holder includes a locking portion. At least one member of the holder and the needle cover includes a protruding portion that protrudes toward the other member, and the other member includes a restriction portion that abuts on the protruding portion to restrict relative displacement of the needle cover with respect to the syringe along the axial direction of the syringe from the protection position toward the use position.

Abstract: A sprayer includes a barrel, a finger grip, a gasket, a rod, and a plunger slidably attached to the rod and capable of contacting the rod and pressing the rod toward a distal side. The plunger includes a contact member which is brought into contact with the finger grip, and a first pressing surface provided at a proximal end thereof. The rod includes a second pressing surface provided at a proximal end thereof. The contact member is brought into contact with the finger grip to restrict the movement of the plunger toward the distal side with the gasket positioned between a distal end and a proximal end of the barrel.

Abstract: A syringe-shaped spraying device includes: a barrel; a nozzle; a packing disposed therebetween; and a core disposed inside the nozzle. The nozzle is connected to a connecting portion provided at a front end of the barrel. The nozzle has a first facing surface facing a front end surface of the connecting portion and a second facing surface facing an outer circumferential surface of the connecting portion. The outer circumferential surface is provided with an annular recess portion, and the second facing surface is provided with a first annular protrusion portion and a second annular protrusion portion. By engaging the first annular protrusion portion with the annular recess portion, the packing is compressed in an axial direction by the front end surface and the first facing surface. The second annular protrusion portion is in pressure contact with the outer circumferential surface of the connecting portion entirely in a circumferential direction.
