Abstract

Containers for automatic injectors and automatic injectors adapted for those containers are disclosed. The containers include structures adapted to retain and, optionally, cripple the needle of the automatic injector when the automatic injector is inserted into the container after use. Depending on the embodiment, an indicator may be included, either as part of the container or as part of the automatic injector, to indicate whether or not the automatic injector has been used. If the indicator is provided as a part of the automatic injector, a corresponding portion of the container may be formed of a light permeable material. The container may also include features, such as an eyelet over the closed end, designed to cushion the automatic injector. Cushioning and shock absorbing features may also be provided inside the container. A clip is also disclosed. The clip is designed to attach two or more containers together.
