Imagine, no more digging through a tipping tower of Tupperware to pack lunch. Somerville- based Cuppow has introduced the BNTO ($7.99 to $10.95), which turns that Mason jar on your shelf into a two-sectioned container for transporting food. The insert is fabricated from 100 percent recycled BPA-free plastic and keeps the components of your meal separate. Think yogurt in the top, cereal in the bottom; vinaigrette suspended above your salad; and as a reward for brown bagging it, Nutella and strawberries for dipping. Available at Tags Hardware, 29 White St., Cambridge, 617-868-7711; Brookline Booksmith, 279 Harvard St., Brookline, 617-566-6660;or go to www.cuppow.com.
