Abstract
The present invention provides for an improved telescoping container, which is set up and collapsed flat quickly and easily, and is provided to the user in one integral piece, eliminating the necessity of a lid being assembled or maintained separately. An integral lid provides an improved amount of cushioning and strength, and does not enter the cubic volume of the container and thus reduce available storage space. In one embodiment of the invention the container gains strength from a double glued seam, having opposing edges sealed to one another with two tabs; alternatively one of the two tabs is sealed. The container sets up by having an inner portion telescope into an outer portion, and may be collapsed flat by pulling the inner portion back out of the outer portion. In one embodiment the ease of set up is further improved by forming the lid from a continuous sheet of material, so that the lid may be closed in one motion, rather than the sequence of steps required with other lids. The lid of this embodiment is composed of multiple layers connected by folds which act as springs, and thus provides a springed, cushioned barrier to protect the contents of the container.
