A substantially paper container has a top end closure adapted to be removed for opening the container and repositioned for closing the container. The container includes a tubular body of substantially paper material, a cup-shaped end closure of substantially paper material and a cup-shaped membrane having an outer upwardly-extending rim portion of substantially the same height as an upwardly-extending rim portion of the cup-shaped end closure. The membrane and end closure are positioned in an open upper end portion of the body in superimposed relationship with the membrane below the end closure. An upper area of the upper end portion of the body extends above the superimposed rim portions of the membrane and the end closure 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 rim portion and an inside surface of the body and between an inside surface of the end closure rim portion and the inside surface of the folded-over upper end of the body. A cut extends circumferentially of the upper end portion of the body and extends inwardly through the body and the membrane rim portion, but not through the end closure rim portion, so that the end closure with the folded-over body upper end portion and the membrane rim portion, which are above the cut, can be removed from and replaced in the body upper end portion.

[ What is claimed is:] [1.] A substantially paper container having a top end closure adapted to be removed for opening the container to dispense some of product contained therein and repositioned for closing the container to store the remaining product therein, said container comprising:a tubular body member of substantially paper material and having inside and outside surfaces and open upper and lower opposed end portions;a cup-shaped end closure member of substantially paper material and having outer and inner surfaces and defining a generally flat center portion and an outer upwardly-extending rim portion of predetermined height and surrounding said center portion;a cup-shaped membrane member having outer and inner surfaces and defining a generally flat center portion and an outer upwardly-extending rim portion of predetermined height substantially equal to said height of said end closure member rim portion and surrounding said center portion;said cup-shaped membrane member and said cup-shaped end closure member being positioned in said open upper end portion of said body member in superimposed relation with said membrane member below said end closure member and having said inside surface of said membrane member adjacent said outside surface of said end closure member along substantially the height of said rim portions and having said outside surface of said membrane member rim portion contacting said inside surface of said body member;an upper area of said upper end portion of said body member extending upwardly above said superimposed rim portions of said membrane member and said end closure member and being folded inwardly over and around upper ends of said superimpose rim portions so that said inside surface of said folded-over upper end of said body member is in contact with said inside surface of said end closure member rim portion;bonds between said outside surface of said membrane member rim portion and said inside surface of said body member and between said inside surface of said end closure member rim portion and said inside surface said folded-over upper end of said body member; anda cut extending circumferentially and substantially around said upper end portion of said body member and extending inwardly through said body member and said membrane member rim portion, but not through said end closure member rim portion, so that said end closure member with said folded-over body member upper endportion and said membrane member rim portion above said cut can be removed from and replaced in said body member upper end portion below said cut.
