发明名称 A SUBSTANTIALLY PAPER CONTAINER
摘要 A substantially paper container has a top end closure adapted to be removed for opening the container to dispense some of the product contained therein and repositioned for closing the container to store the remaining product therein. The container includes a tubular body of substantially paper material, a cupshaped end closure member of substantially paper material and a cup-shaped membrane member having an outer upwardly-extending rim portion of substantially the same height as an upwardly-extending rim portion of the cup-shaped end closure member. The membrane member and end closure member are positioned in an open upper end portion of the body member in superimposed relationship with the membrane member below the end closure member. An upper area of the upper end portion of the body member extends above the superimposed rim portions of the membrane member and the end closure member and is folded inwardly over and around the upper ends of the superimposed rim portions. Bonds, preferably heat-sealed bonds, are formed between an outside surface of the membrane member rim portion and an inside surface of the body member and between an inside surface of the end closure member rim portion and the inside surface of the folded-over upper end of the body member. A cut extends circumferentially and substantially around the upper end portion of the body member and extends inwardly through the body member and the membrane rim portion, but not through the end closure rim portion, so that the end closure member with the folded-over body member upper end portion and the membrane member rim portion, which are above the cut, can be removed from and replaced in the body member upper end portion, which is below the cut.
