About this category

Containers are everywhere - drinkware, food storage, lunch boxes, takeout and retail packaging - and small structural ideas can turn a commodity into a product with a clear selling point. The first patent in this collection separates a container into two layers: a rigid, optionally transparent shell for shape and grip, and a soft silicone liner that holds the food or drink, seals against the lid and lifts out for washing. The same idea covers cups, divided lunch boxes and collapsible versions, and lets a brand mold its logo right through the base.

Each patent was filed only in China. Our pages explain the design, the materials and the variants that can be built from it.

What to look for in this category: food-contact compliance for every material that touches food (FDA rules in the US), honest dishwasher and microwave claims, and tooling planning - shells, lids and silicone liners each need their own molds.

The collection now includes a child-resistant medicine box made entirely of paperboard: folded spring locks on three walls hold the lid, and it opens only when all three press points are pushed at once.
