The closure is the only containment on a boat. Which makes this the most important page here.

What is here

368 continuous thread, 39 child resistant, 26 dome lids, 26 spouted, 18 flip top, 11 liners and sealing discs, 10 round tubs, 7 specialty, 7 buttress, 6 phenolic, 3 lug and twist, 2 trigger sprayers.

Two trigger sprayers

Stated again because it is the central gap. The archetype behind this shelf exists for the trigger sprayer and the shelf has two.

The continuous thread cap is what you actually get

368 of them, and for a marine product that is not a bad outcome: a plain cap with the right liner seals better under motion than any dispensing closure.

Which is the trade-off to state plainly

Dispensing convenience against sealing reliability. On a boat the seal wins, and a product poured from a plain bottle is safer than one that weeps from a sprayer in a locker.

The liner is the specification

11 liners and sealing discs. Every leak in this property is a liner failure before it is a closure failure, and the liner is the line nobody puts on the order.

Spouted closures for the oils

26 of them. Pouring thick oil into a small fill hole is the actual task, and a spout is the difference between that and a sheen.

Phenolic where the chemistry is hard

6 of them. The traditional closure for a solvent or an aggressive cleaner, and the smallest relevant set on the shelf.

The 39 child resistant closures

Not required by anything in this property, and a boat is a confined space with children on it. For a cleaner stored in a cabin that is a reasonable voluntary choice.

Necks to standardize on

54 at 70-400 and 54 at 89-400 for the jars; 49 at 24-410 and 38 at 38-400 for the bottles. Two jar necks and two bottle necks covers the group.

And carry spares aboard

A cap lost over the side is an open container in a locker. For a boat the spare closure is a safety item rather than a convenience.

The archetype behind this shelf is home-spray: 350 to 1,000 mL, narrow mouth, trigger sprayer, PET and HDPE, cold fill, thin, aqueous, sprayed. Its stated reason is "cleaning spray. Trigger sprayer, lockable, chemical resistant." All three leaves sit on it, and the shelf carries two trigger sprayers out of 526 closures.

40 CFR 110.3, discharge of oil in such quantities as "may be harmful" under section 311(b)(4) of the Clean Water Act. Such discharges are those that "(a) Violate applicable water quality standards" or "(b) Cause a film or sheen upon or discoloration of the surface of the water or adjoining shorelines or cause a sludge or emulsion to be deposited beneath the surface of the water or upon adjoining shorelines". law.cornell.edu
