Closures

What is here
145 continuous thread, 37 disc top, 31 lotion pumps, 26 spouted, 19 flip top, 14 phenolic, 11 treatment pumps and 6 specialty.
The pump is the amenity closure
31 lotion pumps and 11 treatment pumps. For a larger in-room bottle used across several guests, a pump is the object that makes it feel deliberate rather than leftover.
The disc top is the practical one
37 of them. One-handed, wet-handed, no dip tube to fail, and far cheaper than a pump. For a shower product it is often the better engineering answer.
The archetype names the real requirement
"Leakproof under pressure change is the whole requirement." That is written for travel, and it is equally true of a bottle shipped by air to a property or carried home by a guest.
Which is a closure test rather than a bottle test
Pressure change finds the closure. Fill a unit, seal it, and take it through a flight or a simulated altitude cycle before committing to a format.
Tamper evidence for a shared space
A bottle in a shared bathroom benefits from showing it has not been interfered with. The shelf is thin on this, and a sealed liner or a band is worth asking about specifically.
Necks worth standardising on
24-410 at 170 and 20-410 at 96. Both carry pumps and disc tops, so a range built on either keeps the dispensing decision open across sizes.
And cleaning for a refill model
If the bottle is refilled rather than replaced, the closure has to come apart and go back together reliably. A pump that cannot be cleaned is a pump that will not be.
So pick the closure for the room, not the shelf
A retail pump is judged in a hand; a hotel pump is judged after three weeks of strangers using it with wet hands. Those are different tests and only one of them happens before you buy.
