Bottle samples
Send production-intent bottles rather than early mock-ups if possible. Material, sidewall strength, base shape, shoulder profile, label position and neck finish can all influence bottle handling through the capping station.
If bottle supply varies, include the lightest or most flexible bottle as well as the standard sample. The most unstable pack is often the one that defines the machine setup.
Cap samples
Send caps from the intended supplier and include alternatives if there are several possible closures. Differences in thread quality, liner behaviour, height, grip surface and cap rigidity can change the preferred capping route.
For pumps and trigger sprayers, include complete closures with dip tubes. Dip tube length, curve, stiffness and orientation can affect whether the closure can be fed automatically or needs assisted placement.
Product and fill weight
The product itself does not always touch the capper, but fill weight and product behaviour can still matter. A heavy liquid may stabilise the bottle, while a foaming or low-fill pack may require more gentle handling.
Where product samples cannot be sent, provide a filled-weight equivalent so bottle stability can be assessed more realistically.
Data to include
Include target output, bottle dimensions, cap dimensions, cap type, desired automation level, available space, upstream and downstream equipment, utilities, changeover requirements and any known torque target.
The stronger the sample pack, the faster Lancing UK can distinguish between semi-automatic, compact, inline spindle, trigger-sprayer or cap-feeding routes.
Quick answers
How many samples should I send?
Send enough bottles and caps for handling, torque and changeover checks, especially if several formats are involved.
Can photos replace physical samples?
Photos help at the early stage, but physical samples are better for final machine selection.
Should I send filled bottles?
Filled or weighted bottles are useful when fill weight affects stability.
