Specialized Packaging Presentation System Secures Door Cylinders During Display and Transport

Door cylinders require protective packaging that prevents movement during shipping while remaining accessible for display and inspection. Traditional cardboard boxes offer minimal restraint, allowing cylinders to shift and sustain damage. Retailers struggle to present cylinders in ways that protect them while allowing customers to assess fit and finish. This innovation introduces a presentation arrangement combining a cardboard packaging receiver with strategically positioned fastening openings and stabilizing devices that allow merchants to secure door cylinders for transport while enabling clean removal and installation in customer applications.

The Problem

Door cylinders, including double cylinders and knob cylinders, arrive at retail and distribution centers in various packaging formats. Standard cardboard boxes provide basic containment but offer little protection against impact. Cylinders frequently rotate or shift during transport, damaging finish and compromising security features. Retail displays expose merchandise to handling by numerous customers, risk of dropping, and theft attempts, yet cylinders must remain presentable.

Merchants wanting to demonstrate how cylinders fit specific doors face packaging constraints. Presentation systems should allow customer inspection of keyways, finish, and dimensions without requiring complete unboxing. Professional installation requires cylinders to be oriented correctly and positioned accurately, yet packaging often creates confusion about proper orientation. The packaging must also serve contractors and end-users who require secure storage between installation and use.

What This Invention Does

The presentation arrangement comprises paperboard or cardboard packaging with a specially designed receiver for the door cylinder. The receiver includes an outer wall with a fastening opening through which a fastening device can be guided. This fastening device (typically a screw) can engage a cylinder fixing screw bore in the inserted door cylinder.

The fastening opening is precisely positioned so that when a screw is inserted and tightened into the cylinder’s fixing bore, the cylinder becomes fixed to the receiver. This creates a mechanical lock that prevents movement during transport while the fastening remains visible, allowing installers to immediately see proper installation orientation.

A stabilizing device integrated into the packaging supports proper cylinder positioning during the fastening process. This device prevents the cylinder from rotating or slipping as the user tightens the fastening screw. The arrangement provides visual reinforcement of the correct installation method: the very process used to secure the cylinder in packaging mirrors the actual installation procedure, serving as an educational and confirmation mechanism.

Key Features

• Integrated Receiver Design. The receiver molded or formed from the packaging substrate accepts the cylinder precisely, maintaining its alignment and preventing rotational movement.
• Fastening Opening Architecture. A strategically positioned opening through the receiver outer wall allows a screw to pass directly through to the cylinder’s fixing bore. The opening diameter matches fastening device requirements.
• Dual-Function Fastener. The same fastening screw that secures the cylinder in the presentation package also serves the actual installation function, reinforcing the proper fastening procedure.
• Stabilizing Device Integration. A support surface or guide positioned in the packaging prevents rotation during fastening. This ensures the screw engages the cylinder bore correctly without cross-threading.
• Cylinder Orientation Clarity. The fixed position clearly shows the cylinder’s proper insertion direction, keyway orientation, and adjustment mechanisms. Customers and installers immediately understand correct mounting.
• Protective Packaging Structure. Surrounding material shields the cylinder from external damage while the fastening secures it against internal movement.
• Visual Inspection Window. The packaging design allows customers to see the cylinder finish, keyway quality, and adjustment mechanisms without removing the product from packaging.
• Simple Installation Methodology. The packaging system educates installers through demonstration. The process of securing the cylinder in packaging teaches proper installation procedures.

Who Is Behind It?

ABUS August Bremicker Söhne KG, a leading German manufacturer of locking systems and security products, developed this presentation arrangement for door cylinders. Multiple inventors contributed: Felix Arne Vogel and Meik Rütten are credited on the patent application. The application claims priority from an earlier German patent application filed 30 August 2024. PHILLIPS ORMONDE FITZPATRICK in Melbourne provides Australian patent representation.

Why It Matters

The retail security products distribution channel manages thousands of door cylinders monthly. Damage during transport represents a significant cost driver, particularly for premium products. Presentation packaging that doubles as installation instruction serves retail and professional markets simultaneously.

For end-users and contractors, this packaging approach provides clarity about proper installation that traditional boxes cannot offer. By demonstrating the correct fastening procedure and orientation within the packaging itself, manufacturers reduce installation errors and returns. The standardized presentation approach also simplifies warehousing and inventory management across distribution networks.

The innovation particularly benefits e-commerce retailers selling door cylinders to remote customers who may lack professional installation experience. Clear visual demonstration of proper orientation and fastening procedures, embedded directly in the packaging, reduces support calls and increases customer satisfaction. Professional installers appreciate the protective packaging design that demonstrates best practices while securing products safely for transport and temporary storage.

Related Concepts

A cylinder lock is the pin-tumbler mechanism fitted inside a door handle or deadbolt. The cylinder is a precision component that must remain undamaged in transit, making specialist packaging critical for retail distribution.

Corrugated cardboard is the most common material for consumer product packaging, offering a low-cost substrate that can be die-cut and formed into custom receiver shapes. When combined with mechanical fasteners, it can provide restraint levels traditionally associated with rigid plastic clamshells.
