120 ml Hotel Shampoo Bottle: What to Specify, and Where It Fails
120 ml Hotel Shampoo Bottle in PET: a 24/410 neck with a flip-top. The mistake to avoid is a 0.4 mm wall that collapses in a suitcase.
120 ml Hotel Shampoo Bottle is the standard format for hotel shampoo at this size: PET body, 24/410 neck, flip-top closure.
Almost every complaint in this combination traces to a 0.4 mm wall that collapses in a suitcase — a specification decision, not a moulding defect.
The free Bottle Spec Checker tests whether your neck fits the closure and whether the wall survives a pump stroke.

Why This Combination
120 ml is the volume hotel shampoo is normally sold in, and 24/410 is the neck that size is moulded on. The flip-top follows from the neck, which is why the closure choice is really a neck choice.
The failure we see is a 0.4 mm wall that collapses in a suitcase.
The Neck Decides the Closure
24/410 takes the flip-top and the standard range for that neck.
Testing
The closure is fitted and leak-tested on the filled bottle before packing.
Wall, Weight and Shipping
At 120 ml the shoulder carries the load. Below 0.55 mm a pump stroke deforms it and the pump draws air; 0.65 mm where the closure is heavy.
If the pack ships filled, the carton has to support the shoulder — that is where most transit damage starts.
