Two sides of one counter
On this page11
The shop side
A refill shop buys a drum, a pail or a five gallon cube of detergent, soap or dish liquid, puts it on a stand with a tap or a pump, and dispenses from it. That vessel is bought once and kept.
The customer side
Somebody arrives with a bottle, a jar or a jug, has it filled, and takes it away. That container is bought once and filled many times, which is the whole proposition.
And the shop sells that container too
Because a first-time customer arrives with nothing. A refill shop is in the container business whether it meant to be or not, and the starter bottle is the thing that converts a curious visitor into a returning one.
Which is the half this shelf serves
485 containers with a median of 237 mL. 443 of them are bottles. That is a shelf of take-home containers rather than a shelf of bulk vessels.
The archetype describes the other half
home-pour: 950 to 4,000 mL, jug format, with a spout or a plain closure. Only 82 containers here are over a quart and 23 over a gallon, so the window and the shelf are describing different objects.
Twelve jugs
For an archetype whose stated format is the jug. Said plainly at the start: if you are buying the vessel the shop dispenses from, this is a thin shelf and you should ask.
The home refiller is the third buyer
Somebody decanting a warehouse-size bottle of dish soap into something that fits under the sink, with no shop involved. Same containers, no weights and measures question at all, because nothing is being sold.
Which is the distinction that runs through this property
The law in the next section applies to a SALE. A household moving its own detergent between its own bottles is doing none of this.
And the pantry is the fourth
Dry decanting, flour and rice and pasta into jars. Fifteen jars on this shelf, which is the honest count for a craft that is almost entirely jars.
Read the containers page for what is genuinely here
A good take-home bottle shelf, a thin jar shelf, almost no glass and twelve jugs. The numbers are on that page rather than hidden behind the total.
