Glued Bottle Neck Collar

Retention is mechanical. The bottom holes are large enough to clear the bottle caps, while the top holes are sized to catch just under the caps. The difference in diameter locks the bottles into the trapezoidal tube.

It depends on the bottle weight. Standard board may work for lighter plastic bottles, but heavy multipacks often warrant board with higher tear resistance to help prevent the narrow webs between the holes from breaking when lifted.

Manual application is possible but can be slow without a custom alignment aid to hold the bottles and snap the collar down evenly. It is often paired with automated or semi-automated application equipment.

No. The collar groups the bottles for retail display and carrying, but it does not provide impact protection or vertical stacking strength. The multipacks are usually packed into a master shipper or tray for transit.

The grip relies on the dimensions of the bottle's cap and neck taper. A physical prototype should be tested with the actual filled bottles to ensure the collar snaps on cleanly and holds the weight.

The angled side panels provide the primary billboard space. Because they rest against the bottle shoulders, they remain visible on the retail shelf.

No, the hole pitch and diameters are cut for a specific bottle profile. Mixing different bottle shapes or cap sizes in a single collar will likely cause uneven gripping and failure.

Condensation from refrigeration can weaken standard paperboard, increasing the risk of the neck grips tearing. Moisture-resistant board or finishes are often discussed for cold-chain beverage distribution.
