Soup leaks, curry smells, and wilted salad turn a packed lunch into work, so the container does the heavy lifting. Round glass bases handle fridge, freezer, microwave, and oven (without lids), so you heat and eat without extra washing. Silicone gaskets and snap‑lock latches seal liquids and keep air out on the move. Three nesting sizes, 400 ml, 650 ml, and 950 ml, cover snacks, mains, and family portions and stack cleanly on crowded shelves. Use simple packing steps and quick seal checks to keep soup inside, curry fresh, and salad crisp. The guide below shows how to pick a size and pack each meal.

Choose the right size for each meal

• Use 400 ml for side soup (about 1.5 cups), dal, yoghurt, or snack portions; fits standard lunch bags and supports portion control.

• Pick 650 ml for a full soup serving, ramen with toppings, or a curry portion with 150–200 g rice kept separate if preferred.

• Choose 950 ml for family stew, bulk curry (3–4 servings), or a composed salad with toppings layered on the lid side to keep dressing dry.

• Leave 1–2 cm headspace, so the lid seats flat and the gasket contacts the rim.

• Stack heaviest at the bottom, so latches stay aligned in transit.

• Keep one clean spare to separate crisp items from steam after reheating.

Pack soup without spills

• Cool soup below 60 °C before lidding, so steam does not lift the seal.

• Leave 1–2 cm headspace at the top, so liquid movement does not push the lid upward.

• Wipe the rim, snap latches in a cross pattern, then tilt over the sink for five seconds to confirm no leaks.

• Carry upright in a tote or backpack sleeve; place a folded cloth under the base to cushion bumps.

• Reheat the glass base without the lid; avoid high heat on lids to protect the gasket.

• Let the base cool for five minutes before washing to reduce thermal shock.

Pack curry and protect aroma

• Use 650 ml or 950 ml for saucy curries; a leakproof curry container needs to fill to about 80%, so oil never touches the lid.

• Wipe the rim, check the silicone ring sits flat, then snap latches evenly.

• Keep rice in a separate 400 ml container when you can to avoid swelling and pressure in one sealed unit.

• Wrap the container in a tote sleeve on long commutes to stabilise temperature and reduce sloshing.

• Reheat the base without the lid; stir once halfway to distribute heat evenly and avoid hot spots.

• Transfer leftovers to the smallest size that fits; less air inside slows oxidation and preserves flavour.

Keep salad crisp and dress at the right time

• Use the 950 ml container, so leaves stay loose; compressing salad bruises tender greens.

• Pack crunchy toppings in a small side cup and add at the table to protect texture.

• Keep dressing in a mini jar; add just before eating for salad storage without leaks and soggy leaves.

• Layer wet to dry: juicy veg at the bottom, proteins in the middle, leaves at the top.

• Chill the base 10–15 minutes before packing and store upright so condensation sits on the glass, not on leaves.

• Rotate between 650 ml and 950 ml during the week, so salads do not compress in overfilled containers.

Use heat and cold safely

• Glass bases work in freezer, fridge, microwave, and oven (to 300 °C); lids go in fridge and dishwasher top rack only.

• Avoid moving from oven to a cold surface or freezer to a hot oven; rest at room temperature for 5–10 minutes to reduce thermal shock.

• In the freezer, leave 2–3 cm headspace so expanding liquid does not stress the seal.

• In the microwave, remove the lid or lift one corner to vent, so steam does not build pressure.

• In the oven, place the glass base on the middle rack or a tray and preheat gradually for even heat.

• After heating, rest three minutes before adding cold toppings to avoid surface stress.

Seal checks that prevent leaks

• Inspect the silicone gasket, so airtight lunch containers keep a full perimeter seal.

• Wipe the rim dry and free of oil or crumbs; debris reduces latch pressure and weakens the fit.

• Snap latches in opposite pairs (north–south, then east–west) to balance force across the lid.

• Press the centre lightly after latching; a flat lid with no bowing confirms even gasket contact.

• Tilt test for five seconds over the sink to catch any mis‑seated corner before you pack a bag.

• Replace worn gaskets or stretched bands when tilt tests show seepage; fresh parts restore the seal.

Clean and care for long life

• Wash bases in the dishwasher; lids on the top rack only.

• Remove, clean, dry, and reseat the silicone ring after washing.

• Avoid abrasive pads or harsh chemicals on lids; use a soft sponge to protect latches and channels.

• Store containers dry with latches open, so moisture does not trap in the lid channel.

• Do not stack heavy pots on empty lids; weight can flex latches and distort the seal.

• For odours, soak the base overnight with warm water and baking soda; rinse and air dry.

Plan a week of meals with three sizes

• Batch cook soup in the 950 ml base; portion the next day into 400 ml or 650 ml for grab‑and‑go lunches.

• Use 650 ml for single curry meals with rice; freeze extra with 2 cm headspace and thaw overnight in the fridge.

• Build layered salads in the 950 ml, with hearty veg at the bottom and greens on top; add protein and dressing at lunch.

• Keep a spare 400 ml for snacks like fruit, hummus, or overnight oats; the round shape fits door shelves and bag pockets.

• Label lids with the date using removable tape; clear glass shows contents, labels track freshness.

• Rotate lids and bases during washing so every set dries fully before reuse.

Buy Glass Meal Prep Containers

Pack soup, curry, and salad with confidence in round glass containers that seal tight and stack cleanly across your fridge and bag. Choose the size that fits the meal, leave headspace for liquids, and wipe the rim before you snap the latches, so the silicone gasket seats flat and the seal holds on the go. Reheat the glass base without the lid, cool before washing, and store lids dry with latches open to protect the gasket channel and extend life. For weekly meal prep, use the three sizes to portion mains, sides, and snacks without spills or wasted space. Simple steps keep flavour in and leaks out.
