No disc tops, no lotion pumps, no fine mist sprayers.19 flip tops and 369 plain caps.
What is here
369 continuous thread, 26 dome lids, 26 spouted, 19 flip top, 19 lug and twist, 18 child resistant, 11 liners and sealing discs, 9 phenolic, 7 specialty, 7 spice caps, 7 buttress and 6 round tubs.
What is absent
The archetype names flip top, disc top, lotion pump and fine mist. Three of those four are not on this shelf at all, which is the gap to state plainly.
And it may not matter
For a decant carried in a pack, a plain cap with a good liner seals better than any dispensing closure. The shelf lost the convenience and kept the function.
The liner is the specification
11 liners and sealing discs. Every leak in this property is a liner before it is a closure, and it is the line left blank on the order.
Spice caps for the kitchen
7 of them. A sift-and-pour closure on a small jar is exactly what a camp spice kit wants and 7 is the count.
Child resistant for the treatment chemicals
18 closures. FIFRA section 25(c)(3) survives the device exemption, and a halogen treatment kept at home between trips is a household hazard.
Phenolic where the chemistry is hard
9 of them, for a halogen or an essential-oil-heavy product. The smallest relevant set and the most specifically right.
Standardize on one neck per kit
73 containers at 38-400, 56 at 89-400 and 56 at 70-400 for the jars; 49 at 24-410 for the bottles. One of each covers a whole kit.
Carry one spare cap
A cap lost at a camp site is an open container in a pack. One spare is grams and it is the cheapest insurance in the kit.
And bag everything regardless
No closure is certain under repeated pressure cycles. The bag is not a lack of confidence in the closure, it is what experienced hikers do with anything that would ruin the trip.

The archetype behind this shelf is store-liquid-decant: 15 to 120 mL, narrow mouth, flip top or disc top or lotion pump or fine mist, PET and HDPE, cold fill, thin, aqueous, poured, with "travel decant, leakproof under pressure change is the whole requirement" as its stated reason. All seven leaves sit on it, including fuel decant and fire starter, which are neither aqueous nor cold.
