Abstract
Abstract A bottom-filled, top-dispensing container formed from a single sheet of plastic, such as styrene or the like. The container is so formed that, prior to being filled, it provides an open bottom so that like containers may be vertically stacked one upon the other. The container comprises a hollow substantially square body having an integral top wall, a corner of which provides a pouring spout and a removable cover heat-sealed thereon. The container closure or bottom wall is initially formed as an integral part of the body extending laterally therefrom and being adapted to be folded back upon the container when the latter is filled so as to seal the same.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
A bottom-filled top-dispensing plastic container thermoformed from a single sheet of plastic comprising a. a hollow substantially square open-bottom body including substantially identically shaped side walls, b. a top wall integral with said side walls and of a thickness greater than the thickness of said side walls, c. a closure for the open bottom of said body connected to and extending laterally from one edge of one of said side walls, d. means for connecting said closure to said one edge of one of said side walls and about which said closure is bent into closing position upon the bottom edges of said side walls of said body, e. a section of the plastic forming said top wall adjacent one corner line between juxtaposed side walls as well as a part of said cOrner line, formed to provide a length and thickness so as to have a portion thereof bent back upon itself to form a cover, f. a remaining section of said length of plastic formed to complete said top wall and said side walls defining said corner line and provided with a score line defining a removable spout opening disposed beneath said cover when the same is connected to said remaining section of said portion of said top wall.
