AUnited States Patent O ce 3,335,935 GUSSET CORNER FOLDING BOX .lohn McK. McCallum, Montreal, Quebec, Canada, assignor to Bathurst Paper Limited', Montreal, Quebec, Canada Filed Sept. 21, 1964, Ser. No. 398,488 4 Claims. (Cl. 229-31) VThis invention relates to a paper board c-ontainer having a construction that is especially suitable for corrugated board.
It has been, for many years, common practice to make containers of the knockdown form from paper board. Such containers have been extensively used for packaging items of clothing. For exa-mple, most tailors wrap suits in containers of this type. Hard board has been commonly used as a material because the folding construction depended upon the use of slits and tabs that entered into the slits to hold the container in a set up position. Corrugated board has been little used for containers of this general class because the slit and tab interlocking arrangement for holding the container in the set up position is not suitable to the thick corrugated board. Corrugated board, on the other hand, is in many cases a superior material to hard board because it has greater strength and offers a better protection to the articles that are packaged.
This invention relates to a container that can be supplied in knockdown form and simply assembled without the use of staples and which can be manufactured conveniently out of a corrugated board. Thus, the combined advantages of a knockdown type of container and the strength of corrugated board are achieved with this invention.
Generally speaking a container according to this invention is made from a flat blank that is formed with fold lines and cuts to make the bottom, side Walls and top. One of each communicating side wall is formed with a locking panel that is in close parallel spaced relation to the side wall with which it forms a corner. The locking panel and side wall have tie means formed therefrom that locks them in close parallel spaced relation, the tie means being stricken from and being part of the blank from which the container is folded. The invention will be clearly understood after reference to the following detailed specification read in conjunction with the drawings.
In the drawings:
FIGURE 1 is a view of a blank from which a container according to this invention is formed.
FIGURE 2 is a view of one end of the container as it it being set up.
FIGURE 3 shows the last step in setting up a single corner of the container, and
FIGURE 4 is a cross-sectional view illustrating the operation of the tie means that holds the container in set up position at the corners.
In the drawings FIGURE 1 shows a blank from which a container according to this invention is formed. It is preferably made from corrugated paper board. The board has exceptional strength characteristics and makes a rigid goodlooking container when set up.
The blank has a bottom panel 10, side wall panels 12, 14, 16 and 18, and a top wall 20 which has closure flaps 22, 24, and 26.
When the container is set up, the side walls are folded to assume a vertical position with respect to the bottom. The corner construction at adjacent side walls is the same at each of the four corners and will be described in connection with the corner between side walls 12 and 14.
Side wall 12 has a triangular locking panel 28 connected thereto which is formed along one edge with a notch 30. Side wall 14 is formed with a tab having a neck portion 32 and a head portion 34. The tab constituted by the 3,335,935 Patented Aug. 15, 1967 neck 32 and head 34 cooperates with the notch 30 to Iform a tie means to secure the corner in set up position as Will be apparent later. A second fold panel 36 is formed to complete the corner construction. It is formed with a notch 38 to permit the neck 32 of the tab to pass as will be apparent later.
It will be noted that the notch 30 is formed with a restriction 40 in its width at a point spaced from its bottom. The restriction is less in width than the unflexed width of the neck 32 of the tab, but greater in width than the flexed width of the tab so that the tab when flexed can pass through the restriction, but when permitted to unilex reasserts itself to lock itself into the bottom portion of the notch 30 below the restriction.
The vari-ous walls and panels yare joined to each other by a weakened fold line according to standard box making practice.
In order to set up a blank as illustrated in FIGURE 1, one actuates adjacent side walls to a vertical position and guides the locking panel 28 and its companion panel 36 inwardly of the box as illustrated in FIGURE 2. When the adjacent walls are in a set up position at right angles to the bottom of the box, the locking panel 28 is in close parallel relation to the end wall 14, being separated therefrom only by the companion corner panel 36. In this p0- sition, the tab formed by the neck and the head 34 is erect and extending upwardly from the notches 30 and 38. To lock the corner one merely folds the tab downwardly to the position illustrated in FIGURE 3 with the neck of the tab in the notch 30 and the head thereof in parallel relation to the locking panel 28, As the neck is forced to the bottom of the notch 30, it passes and is flexed by the restriction 40 in the notch 30. The restriction 40, as noted from the drawing, is spaced from the bottom and from the top of the notch 30. As it passes the narrowest point in the restriction, it reasserts itself again against the side of the notch. In this position, the restriction 40 holds it in the bottom of the notch. Notch 38, as will be noted, is sufficiently large to provide clearance for the neck 32 of the tab, when the neck is iiexed. The head 34 is then bent to lie in parallel relation to the side iiap 28.
The corner once set up, as illustrated in FIGURE 3, is a secure corner formation. All four corners are set up in a similar fashion. Following this, the flaps 22, 24, and 26 of the lid are bent into place and as the lids close they slip inside of the box to form a secure and strong box for container construction.
Embodiments of the invention other than the one illustrated will be apparent to those skilled in the art and it is not intended that this invention should be restricted to the embodiment illustrated.
