Overview & background
Baby-food jars are deliberately plain and conservative because the category is risk-averse. The squat, wide-mouth shape lets a parent see the food clearly, spoon it out fully and clean the jar easily, while the twist-off cap with a pop-up safety button gives an instantly readable tamper and freshness indicator.
Glass is favoured here for its inertness and the trust it carries with parents — there is no flavor transfer, and the contents are fully visible.
