Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
In a dump bin formed of a one-piece sheet and an erected, four-sided tubular shape with a lower base and an upper tray to receive products for display therein, the improvement which comprises: four side panels projecting inwardly from the sides of the lower base; at least two top panels folded inwardly from the top of the sheet to form the upper tray; each of the side panels being partially severed from the side of which it is a part and being partially joined thereto; the side panels being provided with projections and the top panels being provided with slots to receive the projections such that when the tubular shape is erected, the inwardly projecting side panels interlock with the inwardly folded top panels to make the support for the upper tray stable.
Claim 2
Dependent Claim
133 words
In a dump bin formed of a one-piece sheet and an erected, four-sided tubular shape with a lower base and an upper tray to receive products for display therein, the improvement which comprises: four side panels projecting inwardly from the sides of the lower base; at least two top panels folded inwardly from the top of the sheet to form the upper tray; each of the side panels being partially severed from the side of which it is a part and being partially joined thereto; the side panels being provided with projections and the top panels being provided with slots to receive the projections such that when the tubular shape is erected, the inwardly projecting side panels interlock with the inwardly folded top panels to make the support for the upper tray stable.
Claim 3
Dependent Claim
51 words
The invention of claim 1 wherein: there are four top panels; there is a projection on each edge of two opposite top panels; and there is a slot adjacent each edge of the other two opposite top panels to receive a projection and to impart further stability to the upper tray.
Claim 4
Dependent Claim
28 words
The invention of claim 1, wherein the inwardly projecting side panels are scored and bent at an angle to make the support for the upper tray more stable.
Claim 5
Dependent Claim
