Unfoldable laminar tub for the packaging, cooking and delivery of popcorn

Abstract

This invention relates to the field of receptacles for the carriage and cooking of food. More particularly, this invention refers to an unfoldable laminar tub for the packaging, cooking and delivery of popcorn, which being capable of being spread and assembled is useful for the packaging and carriage of corn kernels as well as for its cooking and delivery.

1 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, which, being used for the cooking by a microwave oven of corn kernel including those prepared for cooking without fat matter, is useful as a packaging means, cooking chamber of kernels and container of popcorn, comprising:
 A die-pressed laminar sheet having folding and/or cutting lines which make it capable of being folded and unfolded,   
       characterized in that it comprises:
 a closed packaging receptacle capable of containing a portion of kernels suitable for cooking without fat matter; 
 detachable laminar edges which, commonly leaned, closed the access to said closed receptacle; 
 at least a base portion that, being transversally unfoldable with regard to the adjacent side walls, determines the widening of the receptacle until forming a cooking chamber of the kernels contained therein; 
 said cooking chamber being comprised of at least a depressible head portion which provides a top closure of said widened receptacle; and 
 said depressible head portion is capable of being opened for the conversion of said cooking chamber into a delivery container. 
 
     
     
         2 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that it is constituted by a die-pressed laminar sheet comprising a cellulosic material. 
     
     
         3 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that the detachable laminar edges are extensions of the side walls, to which regard said edges are delimited by respective cutting or weakness lines. 
     
     
         4 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that the base portion, which determines the widening of the receptacle until forming a cooking chamber of the kernels contained therein, is transversally unfoldable with regard to the adjacent side walls by means of a central folding line, which depression into the receptacle is enabled by the proximal base folding lines which, being in an active position, determine the raising of the base portion and the side widening of the receptacle. 
     
     
         5 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that in the side edges, it comprises respective supporting side portions which in relation to the adjacent side walls are transversally unfoldable until becoming a transversal widening support of the receptacle forming the cooking chamber of the kernels contained therein. 
     
     
         6 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 5 , characterized in that each side supporting portion comprises a side folding line which depression into the interior of the receptacle is made possible by means of proximal supporting folding lines which, in an active position, determine its construction as a supporting means of the receptacle widening. 
     
     
         7 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that it comprises two head portions which, as extensions of the respective side walls, are depressible until becoming superimposed as a top closure of the cooking chamber. 
     
     
         8 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that at least one of the side walls is laterally extended thus forming at least a linking flange with the opposite side wall. 
     
     
         9 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 8 , characterized in that one of the side walls forms linking flanges with the opposite side wall. 
     
     
         10 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 8 , characterized in that each side wall forms at least a linking flange with the opposite side wall. 
     
     
         11 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 8 , characterized in that the linking flanges end in bottom ends constituting standing means. 
     
     
         12 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that the front port and the rear part of the laminar sheet remain delimited by a central folding line of the base portion. 
     
     
         13 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that the front part and the rear part of the laminar sheet remain delimited by a lateral folding line which also delimits both side walls by one of their respective side edges while the opposite side edges and the base portion have respective flanges for the linking thereof. 
     
     
         14 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that it comprises at least one partially die-pressed folding line. 
     
     
         15 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that it comprises partially die-pressed base folding lines. 
     
     
         16 . UNFOLDABLE LAMINAR TUB FOR THE PACKAGING, COOKING AND DELIVERY OF POPCORN, according to  claim 1 , characterized in that it comprises partially die-pressed supporting folding lines.
