Title: Flap picnic bag

Description:
BACKGROUND OF THE INVENTION  
       [0001] (a) Field of the Invention  
       [0002] The present invention is related to flap picnic bag, and more particularly, to one used to contain food and dinning set, comprised of ice bucket pocket, partitioning panel, and trolley frame in the rear to achieve purposes of being foldable, separating hot and cold meals and facilitating to carry on the ground.  
       [0003] (b) Description of the Prior Art:  
       [0004] Picnic bags or buckets generally available in the market come in versatile types and usually they are either provided at top a handle or a shoulder strap for carriage. A zipper or a flap lid sewn with a zipper is provided at the top to serve as the entry for putting objects into or out of the bag. However, such configuration of the prior art prevents from achieving a reduced size for storage when not used. When in use, all dinning sets, dishes, hot and cold edibles can easily bump into each other, the edibles are vulnerable to get soured for lacking in sufficient separation. The efforts taken to fumble for the dinning set may spoil the fun of having a picnic. Furthermore, carrying a fully loaded bag either by hand or by shoulder may be too heavy.

       [0006] Another purpose of the present invention is to provide a flap picnic bag, within, a magic tap is vertically provided between the front and the rear flaps from the four continuous flaps, and the upper end of the magic tape externally extends to one side flap; another magic tape is laterally provided on the upper part of the inner wall of that side flap to hold the ice bucket pocket and the partitioning panel detachable.  
       [0007] Another purpose yet of the present invention is to provide a flap picnic bag, within, a foldable hard baseboard is provided at the front edge of the bottom flap of the four continuous flaps to form a solid bottom to fold in the flaps.  
       [0008] Another purpose yet of the present invention is to provide a flap picnic bag, within, a refractory layer is provided on the inner wall at where the ice bucket pocket and on the partitioning panel to keep cooling effect for the ice bucket pocket by fending off the heat.  
       [0009] Another purpose yet of the present invention is to provide a flap picnic bag, within, a detachable pocket is provided externally to the front flap of the four continuous flaps that can be fully opened up, a fastener is provided to the inner wall of the detachable pocket to receive dinning sets and dishes in place.  
       [0010] Another purpose yet of the present invention is to provide a flap picnic bag, within, the bag functions as a traveling suitcase when not provided with the ice bucket pocket.
