PROBLEM TO BE SOLVED: To provide a discardable container with which an injection needle screwed with an injector body can be easily and reliably detached from the injector body and discarded.SOLUTION: A discardable container 1 has a container body 3 and a cap 2, wherein an attaching portion 4 enabling a pen-type injector 10 to be detachably attached thereto is formed on a top plate 21 of the cap 2. A hole portion 41 is formed on the center of a bottom portion 401 of the attaching portion 4. A plurality of protruding pieces 43 capable of engaging with the base end surface of a hub 13 of the injection needle 14 are formed so as to protrude toward the center axis of the attaching portion 4 in the inner circumferential surface of the upper end portion of the hole portion 41. In a state where the pen-type injector 10 is attached to the attaching portion 4, the protruding pieces 43 each protrude toward the pen-type injector 10, and are inserted into a gap of the pen-type injector 10. Also, a plurality of ribs 42 to be inserted into a groove 132 of the hub 13 of the injection needle 14 and engaged with the groove 132 are formed to protrude on the inner circumferential surface of the lower end of the hole portion 41. |
