Abstract
A blank and carry-out tray for carrying a variety of food products are provided and the tray is capable of transformation from a storage condition of a substantially flat configuration to an erect and upright useable condition by manipulation of a plurality of foldably connected portions that move similarly to a parallel linkage arrangement and which are provided with a locking mechanism that automatically lock the tray in its upright and useable condition.
Claims16
A carry out tray for food and beverage formed from a blank of paperboard material capable of being folded from a collapsed condition prior to use into an erect useable condition, said tray in its erect usable condition comprising:
- a substantially planar top wall having an integral product receptacle,
- a pair of substantially parallel sidewalls foldably connected to opposite edges of said top wall, said sidewalls being in substantially perpendicular relationship to said top wall,
- a substantially planar bottom wall spaced from said top wall, said bottom wall having an opening and foldably connected in substantially perpendicular relationship to each of said pair of sidewalls,
- a compartment member adjacent said bottom wall, said compartment member having a lock portion extending into the opening of said bottom wall;
- an end member substantially perpendicular to said top wall and foldably connected to said compartment member, said end member being rotatively coupled to said pair of sidewalls;
- and
- an intermediate member foldably connected to said top wall and spaced from said end member and attached to said compartment member to form an open compartment, said intermediate member having a guide portion depending therefrom deflecting said lock portion of said compartment member into the opening of said bottom wall for locking the tray in its erect usable condition.
A carry-out tray for food and beverage formed from a blank of paperboard material capable of being folded from a collapsed condition prior to use into an erect useable condition, said tray in its useable condition comprising:
- a substantially planar top wall having an integral product receptacle;
- a pair of substantially parallel sidewalls foldably connected to opposite edges of said top wall, said sidewalls being in substantially perpendicular relationship to said top wall,
- a substantially planar bottom wall spaced from said top wall, said bottom wall having an opening and foldably connected in substantially perpendicular relationship to each of said pair of sidewalls,
- a compartment member adjacent said bottom wall, said compartment member having at least two integral lock tabs extending into the openings of said bottom wall;
- an end member substantially perpendicular to said top wall and foldably connected to said compartment member and a spacer member, said spacer member being substantially perpendicular to said end member and foldably connected to each of said pair of sidewalls;
- and
- an intermediate member foldably connected to said top wall and spaced from and substantially parallel to said end member and attached to said compartment member to form an open compartment, said intermediate member having at least two integral guide tabs depending therefrom deflecting said lock tabs of said compartment member into the openings of said bottom wall for locking the tray in its erect usable condition.
A method of forming a carry-out food tray from a collapsed lay flat configuration to a substantially erect and upright position wherein said food tray in its upright position includes a top wall, a pair of substantially parallel sidewalls foldably connected to opposite edges of said top wall, a bottom member spaced from said top wall, said bottom member having an opening, a compartment member swingingly secured to said sidewalls and adjacent said bottom member, said compartment member having a lock member adapted to be extended into the opening of said bottom member, an intermediate member foldably connected to said top wall and attached to said compartment member to form an open compartment, said intermediate member having a guide portion depending therefrom, said method comprising the steps of:
- shifting said pair of sidewalls from positions substantially parallel with said top wall and bottom member to positions substantially perpendicular to said top wall and bottom member;
- moving said compartment member and said intermediate member from a first position wherein the lock member of the compartment member is on one side of the opening in said bottom member to a second position wherein the lock member is on a side across said opening opposite said one side of the opening in said bottom member;
- and
- moving said compartment member and said intermediate member from said second position to a third position wherein said tab is inserted in the opening of said bottom member, said step of moving from the second position to the third position including deflecting the lock member with the guide portion to facilitate insertion of the lock member into the opening for locking the tray in its upright and erect position.
A method of forming a carry-out food tray from a collapsed, substantially flat configuration to an assembled substantially upright position wherein said food tray in its upright position includes a top wall, a pair of substantially parallel sidewalls foldably connected to opposite edges of said top wall, a bottom member spaced from said top wall, said bottom member having an opening, a compartment member swingingly secured to said sidewalls and adjacent said bottom member, said compartment member having a lock member adapted to be extended into the opening of said bottom member, an intermediate member foldably connected to said top wall and attached to said compartment member to form an open compartment, said intermediate member having a guide portion depending therefrom, said method comprising the steps of:
- shifting said pair of sidewalls from positions substantially parallel with said top wall and bottom member to positions substantially perpendicular to said top wall and bottom member;
- and
- moving said compartment member and said intermediate member from a first position wherein the lock member of the compartment member is on one side of the opening in said bottom member to a second position wherein said lock member is inserted in the opening of said bottom member, said moving step including deflecting the lock member with the guide portion to facilitate insertion of the lock member into the opening for locking the tray in its upright and erect position.
A carry-out tray for food and beverage formed from a blank of paperboard material capable of being manipulated from a collapsed condition prior to use into an erect useable condition, said tray in its collapsed condition comprising:
- a substantially planar top wall having a product receptacle;
- a pair of substantially parallel sidewalls foldably connected to opposite edges of said top wall, said sidewalls being in substantially perpendicular relationship to said top wall;
- a substantially planar bottom wall spaced from said top wall, said bottom wall having an opening and foldably connected in substantially perpendicular relationship to each of said pair of sidewalls;
- a compartment member adjacent said bottom wall, said compartment member having a lock tab adapted to be extended into the opening of said bottom wall;
- an end member substantially parallel to said top wall and foldably connected to said compartment member, said end member being rotatively coupled to said pair of sidewalls;
- an intermediate member foldably connected to said top wall and spaced from said end member and attached to said compartment member, said intermediate member having a guide tab depending therefrom adapted to deflect said lock tab of said compartment member into the opening of said bottom wall.
A blank of sheet material cut and scored for forming a food and beverage tray comprising:
- a bottom all portion having an opening,
- a top wall portion,
- a first sidewall portion foldably connected to said bottom wall portion and said top wall portion,
- a second side wall portion foldably connected to said top wall portion,
- a compartment member having tabs adapted to be inserted into said opening of said bottom wall, an end member foldably connected along an edge of said compartment member and adapted to be attached to a surface of said compartment member, said end member foldably connected to said first and second sidewalls;
- and
- an intermediate member foldably connected to said top wall portion and having integral guide tabs and adapted to be attached to said compartment member.
