The device provides for a storage container having at least one group of retaining members secured to the interior surface of the sides. Each group of retaining members is generally coplanar with the bottom of the container and each group defines the top of one of a plurality of storage zones located within the interior of the container. One or more domed caps are provided which are dimensioned to slidingly fit within the container and to cover the top of each storage zone. Finally, there is structure located on the edge of each domed cap for engaging the retaining members when a domed cap is placed on the top of the waste materials and compacted below a group of retaining members defining the top of a storage zone. There is also disclosed a method for compacting resilient waste materials for storage and disposal using the device of the invention. ## Claims ### Claim 1 A device for maximizing the density of compacted waste comprising: a storage container having a bottom, elongated sides, and an open top; at least one group of distinct retaining members secured to the interior surface of the sides of the container, each group of retaining members being generally coplanar with the bottom of the storage container; a plurality of storage zones located within the interior of the storage container, the top of each zone being defined by one group of retaining members; at least one domed cap, each domed cap dimensioned to slidingly fit within the storage container and to cover the top of each storage zone; and means located on the edge of each domed cap for engaging the retaining members in each group of retaining members. ### Claim 2 (depends on 1) The device of claim 1 wherein the retaining members are downwardly angled tabs. ### Claim 3 (depends on 1) The device of claim 1 wherein the retaining members comprise: a downwardly angled tab; a hinge disposed on an end of the tab, said hinge being secured to the interior surface of the side of the container; and a spring engagingly disposed between the tab and the interior surface of the side of the container. ### Claim 4 (depends on 1) The device of claim 1 wherein the means located on the edge of each domed cap for engaging the retaining members is an upwardly and outwardly angled lip. ### Claim 5 (depends on 1) The device of claim 1 wherein each retaining member of each group of retaining members is separately mounted on the interior surface of the sides of the container. ### Claim 6 (depends on 1) The device of claim 1 wherein all of the retaining members of each group of retaining members are mounted on a separate wire form with a configuration complementary to the interior dimensions of the container, each of said wire forms being secured to the interior surface of the sides of the container. ### Claim 7 (depends on 1) The device of claim 1 where the domed cap contains vents. ### Claim 8 (depends on 1) The device of claim 1 wherein the storage container is cylindrical. ### Claim 9 (depends on 8) The device of claim 8 further comprising a tubular, detachable sleeve dimensioned to snugly fit within the top of the cylindrical storage container. ### Claim 10 (depends on 8) The device of claim 8 wherein the cylindrical storage container is a drum having at least one interior horizontal cove, and each group of retaining members is positioned adjacent the top of each horizontal cove. ### Claim 11 (depends on 10) The device of claim 10 wherein all of the retaining members of each group of retaining members are mounted on a separate wire form with a configuration complementary to the interior dimensions of the container, each of said wire forms being secured to the inter for surface of the horizontal cove. ### Claim 12 A method for compacting resilient waste materials for storage and disposal in a storage container having a bottom, elongated sides and an open top, said method comprising the steps of: (a) securing at least one group of distinct retaining members to the interior surface of the sides of the container, each group of retaining members being positioned generally coplanar with the bottom of the storage container, and each group of retaining members defining the top of one of a plurality of storage zones located within the interior of the storage container; (b) filling the lowest unfilled storage zone of the container with resilient waste materials; (c) compacting the waste materials; (d) placing a domed cap on the top of the compacted waste materials, said domed cap being dimensioned to slidingly fit within the storage container and to cover the top of each storage zone, and said domed cap having engaging means located on the edge of the cap; (e) compressing the domed cap until the domed cap is below the bottom of the group of retaining members defining the top of the uppermost filled zone; (f) releasing the pressure on the domed cap whereby the domed cap moves upward and engages the group of retaining members defining the top of the uppermost filled zone, forming a capped layer of compacted waste; and repeating steps (b) through (f) until the storage container is filled. ### Claim 13 (depends on 12) The method of claim 12 wherein the retaining members are downwardly angled tabs. ### Claim 14 (depends on 12) The method of claim 12 wherein the retaining members comprise: a downwardly angled tab; a hinge disposed on an end of the tab, said hinge being secured to the interior surface of the side of the container; and a spring engagingly disposed between the tab and the interior surface of the side of the container. ### Claim 15 (depends on 12) The method of claim 12 wherein the engaging means located on the edge of each domed cap is an upwardly and outwardly angled lip. ### Claim 16 (depends on 12) The method of claim 12 wherein each retaining member of each group of retaining members is separately mounted on the interior surface of the sides of the container. ### Claim 17 (depends on 12) The method of claim 12 wherein all of the retaining members of each group of retaining members are mounted on a separate wire form with a configuration complementary to the interior dimensions of the container, each of said wire forms being secured to the interior surface of the sides of the container. ### Claim 18 (depends on 12) The method of claim 12 wherein the domed cap contains vents. ### Claim 19 (depends on 12) The method of claim 12 wherein the domed cap is compressed in step (e) by a ram having a head with a configuration complementary to the domed cap. ### Claim 20 (depends on 12) The method of claim 12 further comprising placing a hollow, detachable sleeve into the top of the storage container to contain waste materials that spring back over the top of the storage container before being capped by a domed cap, said sleeve being dimensioned to snugly fit within the top of the storage container. ### Claim 21 (depends on 12) The method of claim 12 wherein the storage container is cylindrical. ### Claim 22 (depends on 21) The method of claim 21 wherein the cylindrical storage container is a drum having at least one interior horizontal cove, and each group of retaining members is positioned adjacent the top of each horizontal cove. ### Claim 23 (depends on 22) The method of claim 22 wherein all of the retaining members of each group of retaining members are mounted on a separate wire form with a configuration complementary to the interior dimensions of the container, each of said wire forms being secured to the interior surface of the horizontal cove.
