Abstract
ABSTRACT OF THE DISCLOSURE
The invention is a paperboard container with ventilating openings along the corners. The openings are provided by U-shaped cuts that are formed across the fold lines and the fold lines are die-formed to make a depression from the outside of the container, this being the opposite fold line procedure to the normal one.

Description
1079Z4C~ -.
r~his invention relates to a paperboard container that can be opened and closed with a minimum of manipulation and which can also be supplied with effective ventilation.
There is a very strong demand for a container that can be opened and closed with a minimum of manipulation.
One use for sucn containers is the packaging of live bait for fishing. It is common for fishermen to pack their bait in paperboard containers. Bait, customarily, cons~s of dew worms or other cr~w~ng creatures which are packed in -a quantity of moss or the like in a container. Many containers have a removable top that must be twisted or pried from the base in order to get at the contents of the container. These tops are entirely removable so that once removed they must be set down and after the required amount of bait has been taken from the container, the top must be relocated and replaced. Replacement is cumbersome but carelessness in not replacing the top often results in loss of the contents of the container. Notwithstanding this and other short comings of the removable top container, they have, for many years, been used for the purpose of packing items, such as bait.
It is an object of this invention to provide a -container for items, such as bait, that has an opening that can be hinged to and from an open position with a minimum of a manual manipulation.
It is a further object of the invention to avoid the use of an opening that is separated from the container when it is opened.
It is a further object of the invention to provide an opening that can be simply opened and simply closed.

- . . . ' ~ ' , 10'79240 . .
It is a still further object of the invention to provide a container construction wherein breathing holes can be simply incorporated.
With these and other objects in view, a container according to this invention is made of paperboard and has a bottom and hingedly connected side walls and a top panel;
said top panel being formed with an opening flap that is hinged thereto along one of its edges; and that, when hinged upwardly, exposes an opening in said top; said side walls~
connecting with said bottom along a die formed fold line that is depressed from the outside of the container, U-shaped cuts having been made across the fold line, the side walls having separated from the cuts as the walls were set up to form ventilation holes.
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 the blank from which the container i8 formed;
Figure 2 is a view from the opposite sides of the blank of Figure 1 illustrating the crease lines;

In the drawings;
Figure 1 is a view of the blank from which the container i8 formed;
Figure 2 is a view from the opposite sides of the blank of Figure 1 illustrating the crease lines;
Figure 3 is an enlarged illustration of the corner construction at a vent opening;
Figure 4 is a section along the line 4-4 but when the box is in a set-up position; and

Figure 5 shows the box set up but with the reclosable opening being raised.
The container blank has a base 10; side walls 12, 14, 16 and 18; web corner panels 20 and 22 at each corner; a top 24 hinged to side wall 16; a lip 26; and an opening flap 28 defined by a;cut line and hinged to top 24. It is made of chipboard and the fold lines between the hinged panels are die formed but from the bottom rather than the top of the sheet as is usual practice.
The reason that the fold lines are formed from ' the bottom is associated with the formation of the breathing cuts. These cuts 30 are U-shaped, and at the fold lines. They extend across the fold lines. ~he base of the U extends beyond the centre of the crease, and when the fold line is folded in reverse to normal direction so that the concave side that is engaged by the die is on the outside as shown in Figure 3, they separate from the board and form breathing holes. Forming the breathing holes in this way avoids punching small holes at the fold -~
lines. Punching holes have the disadvantage that the punched out pieces can fall into the next sheet to be cut in production. If they fall in a crease, the carton is damaged. Forming the breathing holes in this way has a further advantage that the protruding U-shaped cuts give an easy gripping surface at the bottom corners of the containers as seen in Figure 5.
An overlay sheet 32 of a plastics material, such as polyethylene is applied to the top of the container.
This sheet is permanently secured to the opening flap 28 .:' .. ' . . :
,, - . . .. .. . . .
~ ~079240 and releasably secured to the portions of the top wall 24 that are marginal to the opening that is formed when the flap 28 is raised. Polyethylene is a good material for the overlay sheet 32 and, in the case of polyethylene, the centre portion that overlies the hinged flap 28 is electrostatically treated for gluing to the hinged flap 28. The outer portions that overlie the marginal portions of the opening are not so treated. The portions of the top at the margins of the opening have a tacky adhesive 15 applied thereto. The hinged flap 28 has a permanent adhesive 17 between it and the hinged flap. Thus, as the overlay sheet is applied to the top of the container with an appropriate adhesive 17 applied to the centre portion thereof, it permanently adheres to the hinged opening flap and releasably adheres to the adhesive 15 at the marginal portions of the opening. The overlay sheet is in production applied ~o the blank by a cellophane window machine of standard design.
This arrangement in the finished container permits one to lift a corner of the overlay sheet against the force of the tacky adhesive. As it is lifted, it disengages from the marginal portions of the opening and carries with it the opening flap which is permanently adhered thereto whereby to form an opening in the top of the container as illustrated in Figure 5. This will be referred to again later when the use of the device is described.
In order to assemble the container, it is turned over as viewed in Figure 1 and assembled in a standard machine for a heat sealed web corner carton with hot melt 10'79~:40 closed tri-seal flaps. The se~up is not described in detail because it is well known, but generally speaking, the base of the blank is placed over an opening that is somewhat larger than the base. The base is depressed into the opening. As it is depressed, the side walls slide over the edges of the opening and are moved upwardly.
The corner flaps that constitute the corner construction are actuated inwardly as indicated in Figure 5. When the side walls of the box are at right angles to the base, heat is applied at the corners to fuse the triangular flaps and secure the walls in set up position. The inside surface of the box is coated with a plastics material that is activated by heat and can be sealed by the application of heat.
It will be noted from Figure 3 that the bottom and side walls of the box are folded in reverse direction to the normal direction of fold at the outside corners and that as the side walls are turned upwardly from the bottom of the container, the breathing cuts tend to remain flat and expose a breathing opening in the side walls adjacent the bottom.
The die cutting rules that form the U-shaped cuts are tapered upwardly at their cutting edges so that the cuts are wider at the surface from which the cut is made.
The cut is made from the same surface as the crease lines are formed. When two adjacent panels are folded to form a 90 angle with the wide opening of the cut being the inside corner, the wider top opening does not bind at the fold. The U-tab stays flat in the plane of the panel to which it is secured when the panels are folded 10'~9240 as shown in Figure 3. To achieve this, the panels are folded in the reverse direction to normal for the crease lines.
These U-shaped cuts extend outwardly from the bottom and do form an irregularity along the bottom edge that served to provide a roughened gripping edge for the container. A popular use of the container is as a con-tainer for fishing worms or other fishing bait. These containers are often wet, and a surface that is easy to grip is an advantage for a container of this type.
When the side walls of the container are set up, the container is loaded with contents and the flap 26 is turned inwardly. Following that, the top is closed, the flaps l9, 21 and 23 at the edge of the hinged top are turned downwardly against the side walls and heat sealed thereto. The loaded container can then be shipped.
As indicated, the contents are often fishing bait, and in use the user, wanting to take a piece of fishing bait from the container, lifts a corner edge of the overlay sheet from the marginal portion of the top of the container as apparent from Figure g. As he does so, the overlay sheet separates from the tacky adhesive on the marginal edge of the top and the opening flap is hinged to an open position to expose the contents.
The required amount of contents is removed and then the closure flap is hinged again to the closed position. As it is done so, one applies slight pressure to the marginal edge portions of the container to press the overlay sheet into light contact with the adhesive that is on the top of the container. This again seals ;
, .
1079Z40 , , the opening.
It remains sealed until the requirement for removal of other contents from the container.
The overlay sheet is preferably made of a plastics material, ~uch as polyethylene.
