1. The method of preventing contamination of the discharge end of a beverage container which has a tear out portion in one end of the container and means for tearing the tear out portion of the container to leave a discharge opening in the end of the container at a location where the surfaces of the container, adjacent to said opening, necessarily contact with the lips of a person drinking the beverage directly from said opening, said method comprising:

  • (a) locating the tearout portion in the bottom wall of the container and recessing the bottom of the container so that it forms a compartment between the container bottom and a plane determined by a bottom edge of a side wall of the container with the recess high enough above said plane so that the tear out portion and areas of the container bottom around the tear out portion are spaced from any flat surface on which the container is placed with the bottom of the container confronting said surface,(b) filling the container through the top thereof, and then closing and sealing the top of the container,(c) placing lettering on the side of the container with at least the predominant part of the lettering oriented so that the lettering is right side up only when the container is oriented with its bottom end lowermost,(d) storing and merchandising the container with the compartment containing the tear out portion at the bottom and closed by a surface on which the container rests and with the compartment containing the tear out portion and said means for tearing it protected from dust, dirt and insect sprays by the part of the container covering the compartment.(e) displaying the conainer during merchanising with information displayed that said container opens at the bottom, and(f) continuing the protection of the tear out portion and its adjacent area from contamination after sale of each individual container by placing and supporting said container, even though separated from a merchandizing pack, on an underlying surface to thereby close said bottom compartment during storage by the purchaser while awaiting opening and discharge of the container through said discharge opening.
