Abstract
Abstract A container includes a tubular body section having a plurality of parallel and equally spaced encircling tear lines for tearing of the successive sections from the rest of the container. A telescoping cover closes an open top. The cover has a side wall of the depth of one section and a top wall projecting inwardly into the side wall with an inclined inner side wall so as to project into the container and also define a stacking recess. The bottom wall conforms to the stacking recess and permits convenient stacking. The inward projection of the cover permits the effective minimizing of the air space within the container as the material is removed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
218 words
In the method of storing a successively removed product from a severable container having a tubular body of a constant cross-section and having a plurality of encircling severable parallel lines defining similar sequentially removable body portions for reducing the depth of the container and defining similar end body portions, the steps providing a removable cover telescoped over one end body portion of said container, said cover having an outer encircling side wall of essentially the same cross-section and slidably telescoping over each of said end body portions formed by removal of a body portion, said replaceable cover having an inner projecting wall portion connected to said outer encircling side wall and projecting inwardly to an inner base wall, said inner projecting wall portion extending into the adjacent end body with said cover side wall projecting over the body portion, the depth of said inner projecting wall portion being less than the depth of the outer encircling side wall, successively removing said product, and replacing said cover over the end body portion as the level within the container is reduced until said inner base wall abutts the products, and removing a body portion at least when the product is below a severable line to continuously maintain a minimal gap between the base wall of the cover and the product.
Claim 2
Dependent Claim
218 words
In the method of storing a successively removed product from a severable container having a tubular body of a constant cross-section and having a plurality of encircling severable parallel lines defining similar sequentially removable body portions for reducing the depth of the container and defining similar end body portions, the steps providing a removable cover telescoped over one end body portion of said container, said cover having an outer encircling side wall of essentially the same cross-section and slidably telescoping over each of said end body portions formed by removal of a body portion, said replaceable cover having an inner projecting wall portion connected to said outer encircling side wall and projecting inwardly to an inner base wall, said inner projecting wall portion extending into the adjacent end body with said cover side wall projecting over the body portion, the depth of said inner projecting wall portion being less than the depth of the outer encircling side wall, successively removing said product, and replacing said cover over the end body portion as the level within the container is reduced until said inner base wall abutts the products, and removing a body portion at least when the product is below a severable line to continuously maintain a minimal gap between the base wall of the cover and the product.
Claim 3
Dependent Claim
56 words
The method of claim 1 wherein said inner projecting wall portion of said cover includes an angled side wall connected to said outer side wall and extending inwardly of the outer side wall to an inward inner base portion substantially spanning the container opening and employing angled side wall to guide the cover onto the containers.
Claim 4
Dependent Claim
206 words
A severable container for enclosing of a product comprising a tubular body of a constant cross-section and having a plurality of encircling severable parallel lines defining similar sequentially removable body portions for reducing the depth of the container and defining similar end body portions, closure means for the opposite ends of said container with at least one of said closure means including a replaceable cover telescoped over the end body portion and having an outer encircling side wall of essentially the same cross-section and adapted to slidably telescope over each of said end body portion including such end body portion formed by removal of a body portion, said replaceable cover having an inner projecting wall portion connected to said outer encircling side wall and projecting inwardly to an inner base wall, said inner projecting wall portion extending into the adjacent end body with said cover side wall projecting over the body portion, the depth of said inner projecting wall portion being less than the depth of the outer encircling side wall, said cover being variably slidably telescoped over the end body portion as the level within the container is reduced to maintain a minimal gap between the inner base wall of the cover and the product.
Claim 5
Dependent Claim
206 words
A severable container for enclosing of a product comprising a tubular body of a constant cross-section and having a plurality of encircling severable parallel lines defining similar sequentially removable body portions for reducing the depth of the container and defining similar end body portions, closure means for the opposite ends of said container with at least one of said closure means including a replaceable cover telescoped over the end body portion and having an outer encircling side wall of essentially the same cross-section and adapted to slidably telescope over each of said end body portion including such end body portion formed by removal of a body portion, said replaceable cover having an inner projecting wall portion connected to said outer encircling side wall and projecting inwardly to an inner base wall, said inner projecting wall portion extending into the adjacent end body with said cover side wall projecting over the body portion, the depth of said inner projecting wall portion being less than the depth of the outer encircling side wall, said cover being variably slidably telescoped over the end body portion as the level within the container is reduced to maintain a minimal gap between the inner base wall of the cover and the product.
Claim 6
Dependent Claim
80 words
The container of claim 3 having a bottom wall integrally formed with the side walls of the container and projects downwardly below the lowermost severing line and includes a fold line parallel to and spaced from said severing line, said bottom wall having an inclined wall extending downwardly and inwardly from said fold line to a plurality of overlapping flaps located in face-to-face contact and including interconnecting slots in the two outermost layers for said closing of said bottom wall.
