Abstract: The invention is a container with a storage cavity formed on its outer surface. Many products today come in a container that requires a peripheral part for proper application. Usually, application of these products is difficult without the peripheral part or the tool. Thus, the user is burdened with having to remember where the peripheral part is or remembering to carry the peripheral part along with the product. By integrating a storage cavity into the container, the invention relieves the user of this burden. An exemplary application is in the case of tire sealants. A tire sealant comes in a container and is usually used with a filler tube that is used to transfer the sealant to the tire. With the invention, the filler tube may be securely stored in the storage cavity formed on the sealant container.
