The pump fails before the bottle. In a refill model that is the number that matters.

What is here

268 continuous thread, 39 lotion pumps, 37 disc top, 15 flip top, 13 dome lids, 11 treatment pumps, 9 phenolic, 7 buttress, 7 round tubs, 5 foamer pumps, 5 liners and sealing discs and 5 tub and pail lids.

Five foamer pumps

For the product a refill shop sells most of. Foaming hand soap works because the concentrate dilutes dramatically, which is the easiest economic argument a shop can make to a customer, and five is the count.

The disc top is the household closure

37 of them. One-handed, wet-handed, no moving parts to fail, and cheap enough to replace. For dish soap and shampoo it outlasts a pump.

The lotion pump is the one customers want

39, plus 11 treatment pumps. It feels like the product they used to buy, and it is the component with the shortest life in the whole assembly.

Which is why spares are a product line

A shop that sells a replacement pump keeps a bottle in service for another two years. One that does not watches the customer replace the whole thing or stop refilling.

Plain caps outlast everything

268 continuous thread closures. No moving parts, cheap, and for a bottle that gets poured rather than pumped they are the durable answer.

The liner is still the specification

Five liners and sealing discs. For a cleaner with solvents or a soap with essential oils, the liner decides whether the closure survives repeated exposure.

Spouts for the bulk end

The archetype names a spout, and for a jug of laundry liquid poured into a machine drawer it is right. The jug shelf is twelve containers, so the spouted end is thin.

Standardise the neck before anything else

194 at 24-410, 91 at 38-400, 51 at 28-410. Two necks covers a whole shop, and it is what makes a spares programme affordable.

Count the cycles, not the units

A closure in this category is opened and closed weekly for years. Test it that way, and let the number you measure be the refill count you advertise.

The archetype behind this shelf is home-pour: 950 to 4,000 mL, narrow mouth, a plain closure or a spout, HDPE, cold fill, thin, aqueous, poured, with "bulk liquid, jug format with a spout or a plain closure" as its stated reason. It describes the shop's bulk vessel rather than the container a customer carries home, which is why the shelf sits an order of magnitude below the window.

Written from NIST Handbook 130, 2023 edition, and from the catalog as it stood on 19 October 2026. Handbook 130 is a compilation of model laws rather than federal law, and states adopt it in different forms, from different years, or not at all; the binding text is your state's. Nothing here concerns whether a scale is legal for trade, which is Handbook 44 and a state device approval, or the retail food rules for refilling a customer's food container, which belong to whoever licenses the shop.
