Castellated Syringe Label With Tabbed Anti-Rotation Interlock

The patent extracts the heat shrinking process from the film application method, replacing it with a cold application method using adhesive or friction fit. This removes the harmful thermal exposure while maintaining the secure attachment function of the film to the adaptor and syringe.

The patent replaces the thermal system (heat shrinking) with a mechanical system (adhesive bonding or friction fit). The tabs with engagement features provide mechanical interlocking that achieves secure attachment without requiring thermal energy, thus protecting heat-sensitive compositions.

The patent removes the heat tunnel equipment from the manufacturing process by extracting the thermal shrinking function. The film is applied using simple adhesive coating or friction fit methods that require no specialized capital equipment, thereby reducing manufacturing complexity and capital costs while maintaining reliable attachment.

The patent employs a disposable adhesive layer or simple friction-fit mechanism instead of expensive reusable heat tunnel equipment. This approach uses low-cost materials and simple processes to achieve the same functional outcome of secure film attachment.

The patent segments the film structure by adding discrete tabs with engagement features (such as protrusions or slots) that interlock with corresponding features on the adaptor. This segmentation provides targeted rotational restraint at specific points while keeping the rest of the film application simple and easy to manufacture.

The patent introduces asymmetric engagement features on the tabs and adaptor surface, such as directional protrusions or keyed slots, that prevent rotation in one direction while maintaining simple application. The asymmetric geometry provides inherent anti-rotational security without complicating the overall manufacturing process.
