Abstract
Abstract One form of packing container comprises a relatively thin, inner lining (consisting of a dished or concave base, a cylindrical mid-part and a conical top) of a plastic material and a mechanically rigid outer supporting shell, into which latter the cylindrical part of the lining tightly fits. The transition between conical top and cylindrical mid-part of the lining has a projecting annular edge which slopes downwardly from the cylindrical mid-part so that the lower edge of the conical top is somewhat lower than the upper edge of the cylindrical mid-part.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
A packaging container comprising a plastic element having a substantially concave bottom portion, a cylindrical wall portion above said bottom portion and a conical top portion above the cylindrical wall portion, said bottom portion, wall portion and top portion being integrally formed, the bottom edge of the conical top portion having a greater diameter than the diameter of the top of the cylindrical wall portion and extending therebelow, and a sleeve member of substantially rigid cardboardlike material surrounding said cylindrical portion for supporting said cylindrical portion and maintaining the shape thereof and extending downwardly at least as far as the lowest portion of the concave bottom portion to serve as a base for the container, an integral flange-like annular portion extending from the top circumference of the cylindrical portion outwardly and downwardly to the lower circumferential edge of the conical top portion, the radial width of said flange-like annular portion being greater than the thickness of said sleeve member and the upper edge of said sleeve member engaging the lower surface of said flange-like annular portion to protect the sleeve from deterioration by any liquid which may contact the upper edge of said sleeve member when the contents of said container are poured therefrom.
Claim 2
Dependent Claim
204 words
A packaging container comprising a plastic element having a substantially concave bottom portion, a cylindrical wall portion above said bottom portion and a conical top portion above the cylindrical wall portion, said bottom portion, wall portion and top portion being integrally formed, the bottom edge of the conical top portion having a greater diameter than the diameter of the top of the cylindrical wall portion and extending therebelow, and a sleeve member of substantially rigid cardboardlike material surrounding said cylindrical portion for supporting said cylindrical portion and maintaining the shape thereof and extending downwardly at least as far as the lowest portion of the concave bottom portion to serve as a base for the container, an integral flange-like annular portion extending from the top circumference of the cylindrical portion outwardly and downwardly to the lower circumferential edge of the conical top portion, the radial width of said flange-like annular portion being greater than the thickness of said sleeve member and the upper edge of said sleeve member engaging the lower surface of said flange-like annular portion to protect the sleeve from deterioration by any liquid which may contact the upper edge of said sleeve member when the contents of said container are poured therefrom.
Claim 3
Dependent Claim
30 words
A packaging container as claimed in claim 1 wherein the lower surface of the downwardly and outwardly extending annular portion forms an angle of from about 1*-5* with the horizontal.
Claim 4
Dependent Claim
18 words
A packaging container as claimed in claim 1 wherein the plastic element has a substantially uniform thickness throughout.
Claim 5
Dependent Claim
45 words
A packaging container as claimed in claim 1 and further comprising a non-absorbent coating on the outside of said sleeve member to further protect the sleeve from deterioration by any liquid which may contact said coating when the contents of said container are poured therefrom.
