Abstract

A needle counter device which includes a latch mechanism for securing the device in a closed condition. The latch mechanism preferably consists of a latch member which is integrated into the edge of a lid of the device and which is configured to be received in a corresponding hole or aperture in a base of the device, as this arrangement simplifies manufacturing, as well as increases resistance to deflection and spreads the opening load (i.e., the load used to unlatch the latch mechanism) into a whole side of the part instead of having the load be concentrated at a narrow portion. This latch mechanism can be implemented in connection with a needle counter device as described above, wherein the needle counter device utilizes an adhesive disposed in one or more troughs. Alternatively, the latch mechanism can be implemented in connection with a more conventional needle counter device, such as one which does not include an adhesive disposed in one or more troughs.
