Hinged cap for needle device

A hinged cap device for use with a syringe comprising:

• a needle hub comprising a cavity for fitting onto a syringe tip, said needle hub comprising a needle comprising a needle shaft and a needle tip;
• a cap defining a channel for capturing the needle to shield the needle tip;
• a living hinge connecting the cap to the needle hub;
• a depressable button lock for locking the needle so that the needle is not displacable from the cap;
• said depressable button lock being located on a proximal end of a first side wall of said cap and comprising a pin projecting from said first side wall towards a second side wall of said cap;
• and
• a lock receiving plate located on said second side wall of said cap at a location for receiving said pin.

A hinged cap device for use with a syringe comprising:

• a needle hub comprising a cavity for fitting onto a syringe tip, said needle hub comprising a needle comprising a needle shaft and a needle tip;
• a cap defining a channel for capturing the needle to shield the needle tip;
• a living hinge connecting the cap to the needle hub;
• a locking mechanism on the cap for securing the needle within the cap, the locking mechanism comprising a pin projected from a button lock located on a first side wall of said cap;
• a locking bore located on a second side wall of said cap;
• and
• wherein the pin is engageable within the locking bore to secure the needle within the cap.

A method for manufacturing a hinged cap device for use with a syringe, said method comprising:

• forming a needle hub having a cavity for mounting on a syringe tip and attaching a needle to the needle hub;
• forming a primary cap having a base wall, a first side wall, and a second side wall, which together define a channel, and attaching the primary cap to the needle hub with a living hinge;
• rotating the primary cap so that the needle is captured within the channel defined by the primary cap;
• providing a temporary lock so that when the temporary lock is activated, the primary cap is temporarily blocked from being rotated away from the needle;
• providing a permanent lock so that when the permanent lock is activated, the primary cap is permanently blocked from being rotated away from the needle;
• and
• wherein the permanent lock is located on one of the two side walls and comprises an annular race defining a cavity, a push button comprising a push wall comprising a push surface movable into the cavity of the annular race, and a pin extending from the push wall and configured to extend across the channel of the primary cap when the permanent lock is activated to contact a lock receiving plate on the second side wall.
