One of four is a container
On this page13
Bulk refill
The leaf this shelf is for. A large container the customer buys again, and we hold 26 of them over 946 mL with 13 at one US gallon.
Refill pouch
A flexible package, which is a different manufacturing world from a molded bottle. 55 articles catalog-wide carry pouch, bag, sachet or film in their family name.
That is a name count, not a claim
Whether any of those 55 is a refill pouch is not something the family name establishes, and this property does not assert it.
Concentrate pod
A water-soluble film article, where the package dissolves into the product. Which is the opposite of everything else in this catalog.
And it inverts the refillable question entirely
A pod is single use by design and leaves nothing to refill, which is a coherent answer to the same problem by a different route.
Tablet concentrate
A tablet, which is a dosage form rather than a package. The container around it is a jar or a tube and the tablet itself is the product.
So three of four leaves are outside the catalog
Stated plainly, because a reader arriving for a pod should not work through 83 bottles first.
The one that is here is well served
26 containers over 946 mL in four materials, including 9 PE F style bottles and 9 jugs. Both are the right format for a bulk refill.
And the small end is well served too
57 containers under 120 mL, with 29 at 59 mL. Which is the dispensing container the refill refills.
Which is why the shelf reads as deliberate
Two clusters, an empty middle, and both ends in the same four materials. It matches the use case better than any other shelf here.
There is even a twin neck bottle
One of them. A twin neck is a dosing bottle: squeeze the body and a measured amount rises into the second chamber. For a concentrate that is the ideal article.
And exactly one is a thin offering
Which is worth saying. The right article exists and there is one of it.
