Se t. 27, 1966 o. HUBBARD BAKERY BOXES {5 SheetsSheet 5 Filed March 25, 1965 w A B B U H O m L United States Patent Ofiice 3,275,228 Patented Sept. 27, 1%66 This is a continuation-in-part of my co-pcnding application Ser. No. 210,342, filed July 17, 1962, and now abandoned.
This invention relates to pasteboard bakery boxes and more particularly to divided boxes for containing bread to be delivered from the bakery to the retail outlet.
It is common practice at the present time to deliver bread in a p-asteboard bakery box from the bakery to the retail outlet. Traditionally, these boxes are designed to carry twenty-four loaves of bread in two tiers. The box has a divider and at each end there are flaps for closing the box. Under the present commercial practice, these flaps are secured by string.
I have invented a box with improved means for fastening the flaps which also tends to reinforce the center divider between the two tiers. This results in a box which has longer life. Also, inasmuch as the end fasteners are quicker to operate they will save time and eventually money, i.e. although the box has a higher initial cost, through the saving of labor in tying and untying strings, there would be an eventual monetary saving. In addition the reinforcement of the boxes causes them to last longer and this results in economy.
An object of this invention is to provide a new latch for closing the flaps of bakery boxes.
Another object of this invention is to provide a latch which is quick to close and quick to open.
Another object of this invention is to provide a latch which is an integral, structural part of the box resulting in a more secure box.
Another object of this invention is to provide a latch which is closed by both the natural springiness of the material and the weight of the product within the box.
Another object of this invention is to provide a latch wherein the box is readily collapsed and also the end flaps may be folded at right angles to the remainder of the box.
Further objects are to achieve the above with a device that is sturdy, compact, durable, simple, and reliable, yet inexpensive and easy to manufacture.
The specific nature of the invention as well as other objects, uses, and advantages thereof will clearly appear from the following description and from the accompanying drawing, the difierent views of which are not necessarily to the same scale, in which:
FIG. 1 is a perspective view of a box with improved latch, with the flaps open.
FIG. 2 is a sectional view of a box with the product therein, with both end flaps closed and latched.
'FIG. 3 is an exploded perspective view of the latch elements of one end, enlarged for clarity.
(FIG. 4 is a sectional view of the latch of a box enlarged for clarity showing one side latched and the other side open.
FIG. 5 is a sectional view of a second embodiment of a latch for the box, enlarged for clarity, in the open position. FIG. 6 is a sectional view of the second embodiment of the latch, enlarged for clarity in the latched position.
FIG. 7 is a sectional view of the second embodiment of the latch enlarged for clarity and in a somewhat exaggerated position to show the flexed position of the divider and the latch when the box is loaded with the product.
FIG. 8 is an exploded perspective view of the second embodiment of the latch elements of one end, enlarged for clarity.
As may be seen in the accompanying drawing, the box has a top 10, bottom 12, and sides 14 and 16. Also, there is a center divider 18 extending between the walls 14 and 16. The center divider 18 is parallel to the top 10 and the bottom 12. Topflap 20 is hinged to the top 12. Bottom flap 22 is hinged to the bottom 12. Side flap 24 is hinged to the side '14 and side flap 26 is hinged to the side 16. The box may be collapsed if the flaps extend outward from the sides and the corners wherein the top 10 joins the sides and the bottom 12 joins the sides are folded.
The side flaps 24 and 26 are the same width as the sides 14 and 16. When the side flaps 24 and 26 are folded before the top flap 20 and bottom flap 22, the box is rigid and cannot be collapsed. The box is made of fiberboard corrugated cardboard or pasteboard or similar inexpensive material. When I say the flaps are hinged or that the joints fold, it will be understood that it is not necessary for two pieces to be joined together for special movement but that a single integral piece may be folded, thus forming a hinge.
The box as described above is conventional in every respect and is that which is commonly used on the market today. It is shown in FIG. 2 with loaves of bread or product 28 therein.
According to the first embodiment of my invention male member in the form of bolt 30 it attached to the divider 18 to project from the center thereof. The bolt 30 has round head 32 thereon. The bolt 30 may be attached to the end of a divider 18 or as illustrated it may be connected to elongated middle strap 34 which extends from one end of the divider 18 to the other. It is found that it is easier to attach the bolts 30 to the divider 18 if they include the strap 34. The bolts 30 are co-axial with the longitudinal axis of the box, or approximately so.
The bottom flap 22 has a hole 66 therein which mates with the bolt 30 when the flap 22 is closed. Female connector 38 is attached to the top flap 29 so that when the flap 20 is closed the bolt 30 is aligned with the opening in the connector 38 or is slightly below it.
The connector 38 has a keyhole opening through it. The opening includes circular portion 40 with an elongated narrow slot 42 connecting beneath it. The surface of connector 38 which is toward the inside of the box when the flap 20 is closed has conic depression '44 in it. If the round head 32 of the bolt 38 is pressed against the depression 44, the head will be guided to the circular opening 40 and passed through it. Then inasmuch as the bolt 30 in its normal position is slightly lower than the center of the connector 38, the bolt 30 will be guided into the slot portion 42. The width of the slot 42 is less than the diameter of the head 32 and therefore the flap 20 is held securely in place. The weight of the product 28 upon the divider 18 will furnish additional force for holding the latch closed, i.e., the latch is closed by the springiness of the material inasmuch as the bolt 30 in the normal position is below the central circular opening 48 and also by the weight of the material 28 resting upon the bolt 30. The bolt 30 through the opening in the connector 38 will tend to support the'divider 18.
Around the circumference of the connector 38 there is flange 46 which is means for attaching the connector 38 within the top flap 20. It will be apparent to those skilled in the art that the connector 38 could be secured to the top flap 20 by means such as inegral staples built around its perimeter.
The bolt 30 and the slot 42 prevent transverse movement of the flap preventing .the box from collapsing. This collapse is also prevented by the flaps 24 and 26 inasmuch as they abut tightly between the top 10 and bottom 12 when they are in the closed position. However, it will be appreciated that the latch provides additional restraint in this direction. The box may be collapsed in the normal manner. Also, in some cases it is desirable to fold the 3 flaps 2t), 22, 24, and 26 down so that they are at right angles to the box in the folded position. In such case, the bolt 30 Will form a slight depression 48 in the top flap 20. However, the bolt 30 and its head 32 do not extend sufiiciently far to prevent the top flap 20 from being folded downward.
As shown in FIG. 3 the strap 34 has a rib 59 longitudinally thereof extending from one end to the other. This gives additional rigidity to it and to the divider 18. The rib 58 has a flange (unnumbered) on either side thereof. The section of FIG. 2 is not taken on the center line of the strap 34, but slightly to one side thereof; therefore, the divider 18 and the flange of strap 34 are shown in FIG. 2 as sectioned and the rib 50 is shown in elevation.
Now referring more particularly to FIGS. 5, 6, 7, and 8 it may be seen there illustrated a second embodiment. This second embodiment is quite similar to the first except that male plate member 52. is substituted for bolt 30 and female connector 54 is substituted for connector 38. The second embodiment is similar to the first in that the weight of the product 28 upon the divider 18 causes the elements to move into a more tightly latched position.
The plate 52 has a cross-wise elongated slot 56 in the end thereof. The slot is transverse unto the longitudinal axis of the box and its position is more clearly seen in FIG. 8. The plate 52 is made of synthetic plastic material and has natural springiness. It is illustrated here that the plate 52 is rather short and is secured by adhesives, for example, between the layers of material forming the center divider 18 at the end thereof aligned with the longitudinal axis of the box.
When the second embodiment latch is connected, the fore piece 68 of the plate 52 is depressed downward by the tongue 66. The natural springiness causes it to return to its original position as seen in FIG. 6. The bottom of the plate 52 rests upon the bottom 70 of the slot 64. The weight of the product 28 upon the'ce-nter divider 18 will cause the divider to bend downward due to the natural springiness of the material as seen in FIG. 7. Therefore the end and force piece 68 of the plate 52 will angle upward; the bottom 70 of the latch 54 forming a fulcrum about which the plate 52 bends. Thus the weight of the product 28 upon the center divider 18 cause the elements to latch more securely and the tongue 66 to more secure.y be engaged through the slot 56 within the plate 52.
It will be apparent that the embodiments shown are only exemplary and that various modifications can be made in construction, materials, and arrangement within the scope of the invention as defined in the appended claims:
