Eleven liners. For six leaves whose common enemy is air.

What is here

345 continuous thread, 43 dropper assemblies, 27 dome lids, 19 lug and twist, 16 flip top, 14 phenolic, 11 liners and sealing discs, 8 specialty, 6 dropper tips and caps and 6 round tubs.

The liner is the specification for five of six leaves

Reeds want a stable humidity, strings want no air, rosin wants no dust escaping, and oils want no evaporation. All of those are a seal.

And there are eleven of them

Which is the honest count. For most of this shelf the cap arrives with whatever liner it came with, and that is the component that decides whether the container works.

Droppers for the valve oil

43 assemblies plus 6 tips and caps. Matched to the 96 containers at 20-410, which makes a coherent small applicator bottle.

Dome lids and lug and twist for the bulk jars

27 and 19. A band room cupboard jar opened weekly wants a quick lid, and a reed store opened daily wants one that reseals without a thread.

Phenolic where an oil sits for years

14 of them. Not strictly needed for a mineral oil, and the right choice if a product has solvents or additives in it.

Round tubs for cork grease

6 round tubs and 12 tubs and pails. Applied with a finger, so a wide shallow container with a lift-off lid, which is the nearest thing here to the traditional tin.

Nothing here is case-proof

A closure that survives being dropped in a bag and sat on is not a specification this catalog records, and an instrument case is a rough environment.

Standardise the neck in a band room

A cupboard holding valve oil, cork grease, spare reeds and strings works better on one or two necks, and 96 at 20-410 plus 56 at 89-400 is a sensible pair.

And specify the liner by name

For the five leaves where air is the enemy, it is the line on the order that decides the outcome and the one most often left blank.

The Davis Pack Supply catalog, measured 19 October 2026. The instrument care shelf is 1,026 rows: 525 containers and 501 closures. 5 mL to 500 mL with a median of 118; 30 containers at 15 mL or under, 100 at 30 or under, 207 at 60 or under, 390 at 120 or under. 266 PET, 119 glass, 78 PP, 62 HDPE, and no steel or tins at all. 287 bottles, 224 jars, 12 tubs and pails, 2 tubes. 147 clear, 112 white, 82 amber, 51 blue, 45 natural, 37 black. Closures: 345 continuous thread, 43 dropper assemblies, 27 dome lids, 19 lug and twist, 16 flip top, 14 phenolic, 11 liners and sealing discs, 6 dropper tips and caps, 6 round tubs. Necks: 96 at 20-410, 59 at 24-410, 56 at 89-400, 56 at 70-400.

The archetype behind this shelf is store-small-dry: 15 to 500 mL, wide mouth, PP and PET and glass, cold, solid, chunky, scooped, with "small dry parts, wide mouth to get fingers in, clear so you can see what is inside" as its stated reason. It describes the four dry leaves well and the two lubricants not at all, and the shelf is 287 bottles to 224 jars against a wide-mouth rule.

Written from 21 CFR 172.878 and from the catalog as it stood on 19 October 2026. Nothing here says a food-contact regulation applies to an instrument lubricant; 172.878 is cited as the published specification for white mineral oil, which is the benchmark a manufacturer can either meet or not. The other four leaves have no governing regulation and this property says so rather than borrowing one.
