Prefilled syringe storage tray and package using the same

A prefilled syringe storage tray configured to store a plurality of prefilled syringes, each of the plurality of prefilled syringes comprises a syringe body including a body flange protruding outward at a proximal end portion, a sealing member sealing a distal end opening portion of the syringe body, a gasket slidably stored in the syringe body, a medicine stored in the syringe body, and a plunger for moving the gasket, which includes a gasket pressing portion provided at a distal end, a pressing operation portion provided at a proximal end, and a shaft portion connecting the gasket pressing portion with the pressing operation portion, the prefilled syringe being formed of disposing a part of the shaft portion of the plunger and the pressing operation portion on a proximal end side with respect to the syringe body, the prefilled syringe storage tray comprising:

• a base portion and a plurality of proximal end side storage portion that stands upright from the base portion, each of the plurality of proximal end side storage portions configured to store at least the part of the shaft portion of the plunger of one prefilled syringe of the plurality of prefilled syringes;
• the each of the plurality of proximal end side storage portions includes a shaft portion insertion port for inserting the part of the shaft portion of the plunger, and a pair of insertion port forming portions which are disposed to face a portion which is a side upper portion of the part of the shaft portion of the plunger stored in the proximal end side storage portion and define facing inner edges of the shaft portion insertion port;
• the each of the plurality of proximal end side storage portions further includes a protruding piece extending from the inner edge of each of the insertion port forming portions toward the inner edge of the other insertion port forming portion, a first contact portion which is disposed at a first end of the shaft portion insertion port in an axial direction and with which a proximal end surface of the body flange is capable of coming into contact, and a second contact portion which is disposed at a second end facing the first end of the shaft portion insertion port in the axial direction and with which a distal end surface of the pressing operation portion is capable of coming into contact;
• a distance between the facing inner edges of a pair of the insertion port forming portions is greater than a width of the part of the shaft portion of the plunger, and a distance between the facing inner edges of the insertion port forming portions in a forming portion of the protruding piece is smaller than a width of the part of the shaft portion of the plunger;
• and
• when at least the part of the shaft portion of the plunger is stored in the proximal end side storage portion, the proximal end side storage portion supports the syringe body and the plunger in a state in which the syringe body and the plunger cannot approach each other since the first contact portion comes into contact with the proximal end surface of the body flange and the second contact portion comes into contact with the distal end surface of the pressing operation portion, and the part of the shaft portion of the plunger is prevented from separating from the proximal end side storage portion since the protruding piece comes into contact with the part of the shaft portion of the plunger.

A package comprising:

• a prefilled syringe, the prefilled syringe comprising:
• a syringe body including a body flange protruding outward at a proximal end portion, a sealing member sealing a distal end opening portion of the syringe body, a gasket slidably stored in the syringe body, a medicine stored in the syringe body, and a plunger for moving the gasket, which includes a gasket pressing portion provided at a distal end, a pressing operation portion provided at a proximal end, and a shaft portion connecting the gasket pressing portion with the pressing operation portion, the prefilled syringe being formed of disposing a part of the shaft portion of the plunger and the pressing operation portion on a proximal end side with respect to the syringe body;
• a prefilled syringe storage tray comprising:
• a base portion and a proximal end side storage portion that stands upright from the base portion and stores at least the part of the shaft portion of the plunger;
• wherein the proximal end side storage portion includes a shaft portion insertion port for inserting the part of the shaft portion of the plunger, and a pair of insertion port forming portions which are disposed to face a portion which is a side upper portion of the part of the shaft portion of the plunger stored in the proximal end side storage portion and define facing inner edges of the shaft portion insertion port;
• the proximal end side storage portion includes a protruding piece extending from the inner edge of each of the insertion port forming portions toward the inner edge of the other insertion port forming portion, a first contact portion which is disposed at a first end of the shaft portion insertion port in an axial direction and with which a proximal end surface of the body flange is capable of coming into contact, and a second contact portion which is disposed at a second end facing the first end of the shaft portion insertion port in the axial direction and with which a distal end surface of the pressing operation portion is capable of coming into contact;
• a distance between the facing inner edges of a pair of the insertion port forming portions is greater than a width of the part of the shaft portion of the plunger, and a distance between the facing inner edges of the insertion port forming portions in a forming portion of the protruding piece is smaller than a width of the part of the shaft portion of the plunger;
• and
• when at least the part of the shaft portion of the plunger is stored in the proximal end side storage portion, the proximal end side storage portion supports the syringe body and the plunger in a state in which the syringe body and the plunger cannot approach each other since the first contact portion comes into contact with the proximal end surface of the body flange and the second contact portion comes into contact with the distal end surface of the pressing operation portion, and the part of the shaft portion of the plunger is prevented from separating from the proximal end side storage portion since the protruding piece comes into contact with the part of the shaft portion of the plunger;
• and
• an outer box that stores the prefilled syringe storage tray in which the prefilled syringe is stored.
