29 containers at 59 mL and 13 at one gallon. The gap is the design.

The distribution

5 to 3,785 mL with a median of 59. 57 of the 83 containers are under 120 mL and 26 are over 946 mL.

So only a handful sit in between

Which on every other shelf in this library would read as a gap and here reads as a design. A refill system needs two sizes, not a range.

The small cluster

29 containers at 59 mL, 8 at 15 mL, 7 at 30 mL, and single counts down to 5 mL. Dispensing and sample sizes.

The large cluster

13 containers at 3,785 mL, which is one US gallon, and 6 at 1,893 mL, which is a half gallon. The refill end.

Which is the only shelf here whose shape matches its use case

Most archetypes are a capacity window with a cluster somewhere inside. This one is two clusters and a deliberate gap.

By format

44 jars, 26 bottles, 9 jugs, 3 tubs and pails, 1 tube. The jugs are the gallon end and they have handles.

9 PE F style bottles

Square in plan, stackable, flat sided. The traditional industrial carried-liquid format and the right one for a refill.

7 PE industrial round bottles

Which is the other large format here. Between the F styles, the industrial rounds and the jugs, the gallon end is well covered.

The small end is mostly jars

12 PET single wall jars, 9 double wall round base jars, 7 double wall straight base jars, 5 glass straight sided jars. Which suits a paste or a balm more than a liquid.

And 14 glass boston rounds

Which is the liquid answer at the small end, with a narrow neck for pouring a measured amount.

Buyability

65 of 83 available, 17 not, 1 unrecorded. 20 quote only. 27 full case only, which is a third of the shelf.

The twin neck bottle is the one to ask about

One container, and it is the only metering container in the group. For a concentrate it is the article the category was invented for.

Written from 16 CFR 260.12 and 260.14 and from the catalog as it stood on 19 October 2026. Our own Recyclable specification has exactly one value, Yes, on all 803 rows that carry it, which means a blank and a negative cannot be told apart and a bare Yes is an unqualified claim. Nothing here states whether any container is recyclable or whether programs are available anywhere. The Green Guides are guidance on claims and nothing on these pages describes the rest of them, nor state recycled-content or labeling statutes.
