Description
~o~ CONSTR~CTION
This invention r~lates generally to box constructions) and has to do particularly with a construction of a foldable box adapted to be stamped out of cardboard or like material, which when set up and appropriately glued together, provides a base container portion and a hinged lid portion. The boxes provided herein are suitable for containing food such as hamburgers, hotdogs and the like, but are not limited to that use.
BACRGROUND OF THIS INVENTION
Currently, foldable cardboard containers used in the ~ast-food industry for hotdogs, hamburgers and the like are of a kind which are difficult for the serving persons to close and lock together once the food has been inserted.
Further, such conventional containers are particularly difficult to open again after they have been closed, in such a manner as to preserve the locking mechanism intact. While this does not present a problem to the customer, who merely wishes to open the box and does not expect to re-use it, it does present a problem to the person serving the food who may have placed the hotdog, hamburger etc. inside the package and closad it, before remembering that some additional garnish was desired by the customer. The box must then be re-opened, the garnish added, and the box closed again. With conventional boxes, the closure mechanism is destroyed or torn upon the first re-opening, and it must be discarded and replaced by a new box.
GENERAL DESCRIPTION OF THIS INVENTION
Accordingly, it is an object of an aspect of this invention to provide a box construction in which the closure between a lid portion and a base portion is easily established, and just as easily released without damaging the closure components in any way.
More particularly, this invention provides a box comprising:
a base portion having a front panel and two side panels each joined wîth the front panel at an angled corner, and recess means between the front panel and each side panel at the respective corners, and a lid portion having a normally flat front panel from which -two locking tabs extend in the plane of the panel and constitute extensions of khe panel in opposed dixections, each tab being adapted to engage in a respective recess means when the lid portion is closed against the base portion, said front panel of said lid portion being resiliently deformable by finger pressure applied between the tabs~ to assume a curved shape in which the direct distance between thP. tabs decreases, thereby withdrawing the tabs from engagement in the recess means.

GENERAL DESCRIPTION OF THIS INVENTION
Accordingly, it is an object of an aspect of this invention to provide a box construction in which the closure between a lid portion and a base portion is easily established, and just as easily released without damaging the closure components in any way.
More particularly, this invention provides a box comprising:
a base portion having a front panel and two side panels each joined wîth the front panel at an angled corner, and recess means between the front panel and each side panel at the respective corners, and a lid portion having a normally flat front panel from which -two locking tabs extend in the plane of the panel and constitute extensions of khe panel in opposed dixections, each tab being adapted to engage in a respective recess means when the lid portion is closed against the base portion, said front panel of said lid portion being resiliently deformable by finger pressure applied between the tabs~ to assume a curved shape in which the direct distance between thP. tabs decreases, thereby withdrawing the tabs from engagement in the recess means.
GENERAL DESCRIPTION OF THE DRAWINGS
One embodiment of this invention is illustrated in the accompanying drawings, in which like numerals denote like parts throughout the several views, and in which Figure 1 is a perspective view, taken obliquely from above, o~ a box construction embodying this invention;
r Figure ~ is another pPrspective view, showing the box in a position in which the lid is being releaséd from the base portion;
Figures 3 and 4 are sequential perspective views, taken from 'linside" the closed box, showing the method o~ release;
and Figure 5 is a front elevational view of the box when closed DET~II~lED DESCRIPTION OF l~E DRAWINGS .
Attention is first directed to Figure 1, which shows a box 10 which includes a base portion 12 and a lid portion 140 The lid port.ion 14 includes a top panel 16 of substantially rectangular configuration, from which downwardly and divergingly extend a rear panel (not visible in Figure 1~, two side panels 18 and 19 (side panel 19 is visible in ~igure
2), and a forward panel 21. Attached to the ~orward panel 21 along a creased hinge line 24 is a ~ront panel 26 from which laterally extend two locking tabs 28 and 29.
The base portion 12 has a bottom panel 32 of substantially rectangular configuration, from which upwardly and divergingly extend a front panel 36, two side panels 33 and ~0 and a rear panel 42.
As best seen in Figures 1, 3 and 4 r the front panel 36 of the base portion 12 has two glue flaps o~
which only one is visible in the figures at 44. In the embodiment illustrated, the glue flap 44 is shown to be triangular t although this is not considered a limi-ting configuration. Each glue flap 44 has an opening 46 adjacen-t its connection to the front panel 36, the opening constituting a recess within which the respective one of the locking tabs 28, 29 can lodge when the lid portion 14 is closed against the base portion 12. At least the forward panel 21 and the front panel 26 of the lid portion 14, and preerably the entirety of the box 1~, are constructed of a resiliently deformable material like cardboard such that finger or thumb pressure applied approximately centrally to these panels between the locations o~ the -tabs 28 and 29 will cause the panels to assume a curved shape such as that shown in Figure 2~ in which the dixect distance between the tabs 28 and 29 decreases, thereby withdrawing them inwardly from engagement with the openings 46. As can seen by inspecting Figure 2, the hand of the user, while pushing inwardly with the thu~b in order to withdraw the tabs 28 and 29 from engagement with the openings 46, is also in a position to lift upwardly on the lid portion 14, thus opening the box and revealing the contents.
As can be seen in Figures 3 and 4, the embodiment illustrated is one in which the opening 46 is cut into the glue flap 44 entirely to one side of the crease line 50 joining the glue flap 44 to the front panel 36.
With this configuration, if the side panel 38 completely overlies the opening 46 ~as may be desired for aesthetic reasons) t it will be eviden-t that, for proper functioning, the side panel 38 should not be directly adhered to the glue flap 44 immediately adjacent the opening 46. If this were to take place, then it would be difficult or impossible for the respective locking tab 28, 29 to properly engage in the opening 46. By adhering the glue flap 44 to the side ~3~
panel 38 enly at an area remote from the opening 46, for example in the area 52 which has been stippled in Figure 4, it is possible for the side panel 38 to resiliently deform outwardly away from the glue flap 44 under pressure from the respective locking tab 28, 29.
This is the condition illustrated in Figure 5, where the side panel 38 (at the left of Figure 5) is shown to be somewhat outwardly displaced from the front panel 36, due to pressure from the locking tab 29. The same situation takes place at the righthand side of Figure 5.
While one embodiment of this invention has been illustrated in the accompanying drawings and described hereinabove, it will be evident to those skilled in the art that changes and modifications may be made therein, without departing from the essence of this invention as set forth in the appended claims.
The base portion 12 has a bottom panel 32 of substantially rectangular configuration, from which upwardly and divergingly extend a front panel 36, two side panels 33 and ~0 and a rear panel 42.
As best seen in Figures 1, 3 and 4 r the front panel 36 of the base portion 12 has two glue flaps o~
which only one is visible in the figures at 44. In the embodiment illustrated, the glue flap 44 is shown to be triangular t although this is not considered a limi-ting configuration. Each glue flap 44 has an opening 46 adjacen-t its connection to the front panel 36, the opening constituting a recess within which the respective one of the locking tabs 28, 29 can lodge when the lid portion 14 is closed against the base portion 12. At least the forward panel 21 and the front panel 26 of the lid portion 14, and preerably the entirety of the box 1~, are constructed of a resiliently deformable material like cardboard such that finger or thumb pressure applied approximately centrally to these panels between the locations o~ the -tabs 28 and 29 will cause the panels to assume a curved shape such as that shown in Figure 2~ in which the dixect distance between the tabs 28 and 29 decreases, thereby withdrawing them inwardly from engagement with the openings 46. As can seen by inspecting Figure 2, the hand of the user, while pushing inwardly with the thu~b in order to withdraw the tabs 28 and 29 from engagement with the openings 46, is also in a position to lift upwardly on the lid portion 14, thus opening the box and revealing the contents.
As can be seen in Figures 3 and 4, the embodiment illustrated is one in which the opening 46 is cut into the glue flap 44 entirely to one side of the crease line 50 joining the glue flap 44 to the front panel 36.
With this configuration, if the side panel 38 completely overlies the opening 46 ~as may be desired for aesthetic reasons) t it will be eviden-t that, for proper functioning, the side panel 38 should not be directly adhered to the glue flap 44 immediately adjacent the opening 46. If this were to take place, then it would be difficult or impossible for the respective locking tab 28, 29 to properly engage in the opening 46. By adhering the glue flap 44 to the side ~3~
panel 38 enly at an area remote from the opening 46, for example in the area 52 which has been stippled in Figure 4, it is possible for the side panel 38 to resiliently deform outwardly away from the glue flap 44 under pressure from the respective locking tab 28, 29.
This is the condition illustrated in Figure 5, where the side panel 38 (at the left of Figure 5) is shown to be somewhat outwardly displaced from the front panel 36, due to pressure from the locking tab 29. The same situation takes place at the righthand side of Figure 5.
While one embodiment of this invention has been illustrated in the accompanying drawings and described hereinabove, it will be evident to those skilled in the art that changes and modifications may be made therein, without departing from the essence of this invention as set forth in the appended claims.
