Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 161 words
A container construction comprising a lower section, a raised platform carried by said lower section, said platform having an opening defining an upwardly facing cavity, an upper section swingably connected to said lower section for movement into and out of overlying relation with said platform, a tongue swingably connected to and extending from said upper section into said cavity for movement into and out of the latter upon upper section movement into and out of said overlying relation, whereby an article of contents located in said cavity is movable with said tongue out of and into said cavity upon upper section movement out of and into said overlying relation, a pair of cover members extending from opposite sides of said lower section over said platform and inwardly toward said cavity, a leg depending from each cover member into the adjacent region of said cavity, and ears on said legs extending angulately therefrom into spacing relation between said lower section and platform.
Claim 2
Dependent Claim 161 words
A container construction comprising a lower section, a raised platform carried by said lower section, said platform having an opening defining an upwardly facing cavity, an upper section swingably connected to said lower section for movement into and out of overlying relation with said platform, a tongue swingably connected to and extending from said upper section into said cavity for movement into and out of the latter upon upper section movement into and out of said overlying relation, whereby an article of contents located in said cavity is movable with said tongue out of and into said cavity upon upper section movement out of and into said overlying relation, a pair of cover members extending from opposite sides of said lower section over said platform and inwardly toward said cavity, a leg depending from each cover member into the adjacent region of said cavity, and ears on said legs extending angulately therefrom into spacing relation between said lower section and platform.
Claim 3
Dependent Claim 53 words
A container construction according to claim 1, said legs each extending a substantial distance along a respective side of said cavity to define opposite cavity walls maintained in position by said ears, and fingers on opposite sides of said tongue adjacent to respective cavity walls for holding engagement with the article of contents.
Claim 4
Dependent Claim 15 words
A container construction according to claim 2, said container construction being entirely of sheet cardboard.
Claim 5
Dependent Claim 16 words
A container construction according to claim 2, said container construction being formed of a one-piece blank.
Claim 6
Dependent Claim 63 words
A container construction according to claim 4, said upper section comprising a backing member hingedly connected to said lower section, a face member in facing relation with said backing member and carrying said tongue, said face member having a through cutout for receiving an additional article of contents on said upper section, said platform being recessed to receive said additional article of contents.
Claim 7
Dependent Claim 191 words
A container blank fabricated of a single sheet of stiff bendable material and comprising: a main panel defining a lower section, a plurality of auxiliary panels hingedly connected to said main panel and swingable relative thereto to define a peripheral wall, a platform hingedly connected to one of said auxiliary panels and swingable relative thereto to overlie said main panel and define a platform, said platform having a through hole defining a cavity in said platform, an upper section hingedly connected to another of said auxiliary panels for swinging movement toward and away from said platform panel in its platform defining relation, a tongue swingably connected to said upper section panel and having its distal end engageable in the cavity defined by said platform panel for movement therein upon swinging movement of said upper section panel, a pair of cover panels respectively hingedly connected to another pair of said auxiliary panels for swinging movement into overlying relation with said platform defining panel on opposite sides of said platform cavity, and a pair of leg panels hingedly connected to respective cover panels and extendable into said platform cavity upon opposite sides thereof.
Claim 8
Dependent Claim 191 words
A container blank fabricated of a single sheet of stiff bendable material and comprising: a main panel defining a lower section, a plurality of auxiliary panels hingedly connected to said main panel and swingable relative thereto to define a peripheral wall, a platform hingedly connected to one of said auxiliary panels and swingable relative thereto to overlie said main panel and define a platform, said platform having a through hole defining a cavity in said platform, an upper section hingedly connected to another of said auxiliary panels for swinging movement toward and away from said platform panel in its platform defining relation, a tongue swingably connected to said upper section panel and having its distal end engageable in the cavity defined by said platform panel for movement therein upon swinging movement of said upper section panel, a pair of cover panels respectively hingedly connected to another pair of said auxiliary panels for swinging movement into overlying relation with said platform defining panel on opposite sides of said platform cavity, and a pair of leg panels hingedly connected to respective cover panels and extendable into said platform cavity upon opposite sides thereof.
