In Store Security - (continued) If the bottle is stolen, it can only opened by smashing the bottle. Both upward and downward force is required, but only downward is possible after theft. Any downward pressure will break the glass.
This allows the bottle to be displayed on the shelf instead of behind a desk, without any imposing security device attached. Rather than compromising the packaging (like existing products), this enhances it, and would be very cheap and simple to implement.
