Co-molded rigid cap with integrated rfid and cap end torque transfer features
By embedding an RFID tag in the co-molding process of the rigid cap and extending teeth axially at the distal end of the cap, the problem of RFID tags affecting spline teeth in the prior art is solved, and the effective fixation and torque transmission of the syringe are achieved.

AI Technical Summary
Technical Problem
Existing rigid caps with integrated RFID tags, while controlling the cap diameter, struggle to form effective splines on the cap to achieve external torque transmission, thus affecting the fixation of the cap to the syringe.
Method used
Design a rigid cap by embedding RFID elements between different molded parts or layers of the cap through a co-molding process, and by extending multiple circumferentially spaced teeth axially at the far end of the cap to achieve engagement of a torsion tool and transmission of external torque.
Benefits of technology
While controlling the cap diameter, it ensures the protection of the RFID tag and effective external torque transmission, making it suitable for automated operation and avoiding the problem of syringe jamming.

Abstract
A rigid cap is provided that includes an in-mold portion having a proximal end and a distal end, where the proximal end has an open end and includes a female connector formed on the proximal end, the distal end having a closed end. The rigid cap further includes an RFID element positioned on the inner molded portion at the distal end so as to extend around at least a portion of the distal end; and an outer molded portion formed on the RFID element at the inner molded portion and the distal end so as to enclose the RFID element between the inner molded portion and the outer molded portion, where the outer molded portion has a proximal end and a distal end. The inner molded portion and / or the outer molded portion includes a plurality of circumferentially spaced teeth extending axially from a distal end of the inner molded portion and / or a distal end of the outer molded portion.
