ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
This invention relates to adjustable containers and more particularly, but not by way of limitation, to a multipurpose adjustable container made of a single sheet. The single sheet having a plurality of side panels with vertical fold lines and a plurality of upper and lower end flaps which can be cut or folded for enclosing the container. The vertical fold lines allow the container to be folded into a number of different sizes and geometric shapes for storing and shipping various items.
(b) Discussion of Prior Art
In U.S. Pat. Nos. 1,125,535 to Hoffman, 3,032,253 to Younger, 3,313,467 to Anderskow et al., 3,598,303 to Folz and 3,727,827 to Stice, different types of expandable and variable sized boxes, containers and envelopes are disclosed. Also, in British Patents 371,751 to Montague et al. and 1,029,562 to Hodgkinson two different types of carton blanks are described for making various sizes of containers when folded along slots and perforated fold lines.
The above mentioned prior art patents do not specifically disclose or teach the subject invention having a plurality of side panels for adjusting the length and width of the container along with upper and lower flaps that can be either cut or folded when closing opposite ends of a container of a selected size.
SUMMARY OF THE INVENTION
In view of the foregoing, it is a primary object of the subject invention to provide a multipurpose adjustable single sheet container. Side panels of the container can be quickly folded along vertical fold lines for forming a plurality of different size containers. The container can be folded to different lengths and widths for holding various size objects.
Another object of the invention is the container includes upper flaps and lower flaps which can be cut along vertical perforated lines for folding the flaps inwardly when enclosing the opposite ends of the container.
Still another object of the invention is the upper flaps and the lower flaps also include “X” shaped diagonal fold lines. When a length of the diagonal fold lines is folded, the flaps can be folded inwardly providing an alternate way of enclosing the opposite ends of the container. The user of the subject container has an option of either cutting the perforated lines of the flaps or folding the diagonal fold lines of the flaps when enclosing the opposite ends of the container.
Yet another object of the invention is the vertical perforated lines in the flaps include a inverted “T” shaped cut therein to act as a stop. The “T” shaped cut helps prevent cutting into a vertical fold line between the panels and prior to folding the flaps inwardly when enclosing the ends of the container.
The container includes a plurality of side panels. Opposite sides of the side panels are divided by vertical fold lines. Opposite ends of the side panels include upper horizontal fold lines and lower horizontal fold lines. The upper horizontal fold lines divide the side panels from a plurality of upper flaps. The lower horizontal fold lines divide the side panels from a plurality of lower flaps. Opposite sides of the upper and lower flaps are divided by vertical perforated lines. When a length of the vertical perforated lines is cut, the flaps can be folded inward when enclosing the opposite ends of the container. The upper and lower flaps also include “X” shaped diagonal fold lines. When a length of the diagonal fold lines is folded, the flaps can be folded inward providing an alternate way of enclosing the opposite ends of the container.
These and other objects of the present invention will become apparent to those familiar with the different types of multipurpose container boxes, container blanks and adjustable single sheet containers when reviewing the following detailed description, showing novel construction, combination, and elements as herein described, and more particularly defined by the claims, it being understood that changes in the embodiments to the herein disclosed invention are meant to be included as coming within the scope of the claims, except insofar as they may be precluded by the prior art.
