Octagonal Oatmeal Jars

The octagonal jar has a quietly nostalgic, apothecary character. Eight facets give it more visual interest than a plain cylinder while keeping flat faces for labeling, and it reads a little more architectural than its hexagonal cousin.

It has found a niche with oat, overnight-oat and breakfast brands that want a wholesome, keepable jar the consumer will reuse and display on the counter.

Oats and overnight oats, granola and muesli, dry baking mixes, preserves and honey, nuts and dried fruit. The wide mouth suits dry-goods filling and scooping, and the format crosses easily into refill and zero-waste retail where the jar is meant to be kept.

Its display-friendly look also makes it a good fit for gift ranges and pantry-styling collections, often sold in matched sets of two or three sizes.

Eight molded facets rise to a wide lug or CT mouth. As with any faceted jar, glass distribution between the corners and the flat panels is the key forming consideration, and generous corner radii add strength.

Flat facets give clean, undistorted label panels, and embossing on one or more faces can add to the heritage feel. A label can sit on one facet or wrap across three for more space.

Dry goods are filled cold, so the main concern is keeping moisture out — choose a sealing or airtight lid for cereals and mixes that go stale. For wet, pasteurized preserves, switch to a plastisol-lined lug cap and keep headspace consistent for the vacuum.

The faceted corners are the thinnest points, so avoid hard impacts on the line and in handling.

Press-and-blow forming with an octagonal blank mold defines the facets before the final blow; even wall thickness at the eight corners is the main target and is gauged in quality control. Annealing is tuned to relieve stress at the corners, and the finish is checked for cap fit.
