  • Patent number: 5718368
    Abstract: A food container consisting of a top and a bottom having obliquely angled side elements is disclosed. The container may be cut from a single blank of container material and formed into a hingedly connected top and bottom. When the top and bottom are open and substantially coplanar the obliquely angled sides permit multiple boxes or containers to be nested within one another for efficient stacking. A preferred embodiment includes tops and bottoms with eight side elements comprising one piece side elements and side elements having overlapping panels. When closed, the top side elements overlap the bottom side elements. The container also includes a locking tongue and opening which receives the tongue. A tab may be provided to assist in moving the tongue to disengage it from the opening.

  • Patent number: 5615796
    Abstract: A container for the temporary storage of foods is disclosed. The container includes a corrugated medium having a single backer paper thus creating an exposed corrugated surface on a side opposite the backer. The food container is formed such that the exposed corrugation is located towards an interior surface of the container. The corrugation is provided in a meandering, nonlinear pattern to provide strength along both longitudinal and transverse directions relative to the orientation of the corrugation. By using a corrugated medium having a single layer of backer paper, it is possible to construct the container using approximately one-third less materials without sacrificing strength.

  • Patent number: 5568877
    Abstract: A method of manufacturing a container for the temporary storage of foods is disclosed. The container includes a corrugated medium having a single backer paper thus creating an exposed corrugated surface on a side opposite the backer. The food container is formed such that the exposed corrugation is located towards an interior surface of the container. The method of manufacture involves fabrication of a single-face sheet of corrugated material to which is affixed a tape liner along opposed side edges of the sheet. A wider tape is affixed to the sheet intermediate the lateral edge tapes. The sheet is then cut along a longitudinal midline of the intermediate tape and also across the sheet to form discrete blanks. The blanks are substantially single-face corrugated material but have double-face corrugated material along the lateral edges where the tape was applied. Thereafter, the blank may be further cut, scored and folded to form containers having a single-face,bottom panel and double-face side walls.
