A fill line that reads like a calendar, not a warning

One container, printed full width across the back. A domed lid, a drop-slot, a plain rectangular body. A solid band of yellow rises up from the bottom, well past a third of the height. Across that band, in bold flat capitals: SHARPS.

Nothing else is drawn. No hand reaching for it, no scene around it. Just the shape and how far the band has climbed.

What's actually printed on this shirt?

A plain container, drawn as an object rather than as a scene — the kind of shape you'd get from tracing its silhouette, not from photographing it.

The body is a flat rectangle with a domed lid and a narrow drop-slot at the top. A solid band of colour, distinct from the container's own body colour, marks a level partway up. Bold capitals run across that band. Nothing surrounds the container; the whole back of the shirt is otherwise empty.

Why print a fill level instead of the container alone?

Because the fill level is the actual subject, and the container is just the shape that holds it still long enough to read.

A container on its own is a static object — a lid, a slot, an outline. A band that's climbed partway up turns the same object into a record of time passing: work happened, in some quantity, between an empty container and this one. It's a gauge before it's a warning, the same way a tide mark on a harbour wall or a fuel gauge reads first as a level and only second as anything else.

What determines how high the band sits?

Whatever pace produced it — a slower week leaves the band lower, a busier one pushes it higher, and the container doesn't editorialise about which is which.

That's the whole appeal of using a fill line instead of a number or a chart: it reports a state plainly, the way a set of appointment rows lengthening down a card reports a pace without commentary. The band just says how far up it currently sits.

Is a fuller band a bad sign?

No more than a fuller tide mark is. It's a measure of use, not of trouble — a container that fills is doing exactly what a container is for.

Who owns a container shape like this?

Nobody — a rectangular body, a domed lid and a coloured fill band is a generic container form, drawn plainly rather than copied from any specific real product's actual proportions or markings.

A real supplier's branded container, reproduced with their actual printed instructions or their actual regulatory markings, would be that supplier's material. This one carries a single invented word across a plain band and nothing else — no maker's mark, no regulatory language — which keeps it a drawn object rather than a copy of anyone's real packaging.

Does this work for other shop tools that fill or wear down over a week?

Yes — the same shape works for anything measured in a rising or falling level rather than a count: a tank running low, a spool running out, a jar filling up. What changes is the word on the band; the container and the level underneath it are doing the same job either way.

Does it print well?

Yes, and the fill band is the part that decides it — a hard-edged block of colour holds up on fabric far better than a soft gradient rise would.

Flat colour with a clean edge is close to the easiest case a print gets, where a wide soft gradient goes muddy fast, so the band here is kept as one solid fill rather than a fade, and the cream printed against the olive body needs a proper underbase to hold its own colour rather than reading through as the shirt's own green.

How do I get one made?

Describe the object at JustOG — the container, the word across the band, and how high the level should sit. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.

Designs other people have published are in the shop.

The band sits where it sits this week. Next week it'll be somewhere else.
