Expandable portable bag

Abstract

An expandable portable bag has a bearing plate section, an expandable peripheral side section, eyelet holes, control draw cords, bendable sections and a pull control and carry section to enable the portable containing bag form to be expanded. The portable containing bag can be directly used as a resting mat for a pet or the mat for people for the purpose of playing, resting and warming when the bag is at the expanded state. The bag has the advantage of easy cleaning. The bag significantly improves the practicability and advancement of the containing bag product in terms of the usage function and value.

We claim: 
     
         1 . A kind of expandable portable containing bag, characterized by comprising the following:
 a bearing plate section, in the plate-like body form with a set bearing strength and at a horizontal use state;   an expandable peripheral side section, connected to the external periphery of the bearing plate section and in a circular enclosure form; the expandable peripheral side section can be selected to the horizontally expanded state or vertically folded state relative to the bearing plate section; moreover, the expandable peripheral side section has several bendable sections so that the expandable peripheral side section at the vertically folded state could be gathered together to form a vertical frame enclosure body form and form a box body form and a containing space with the bearing plate section;   several eyelet holes, located at the two alternatively opposite side areas of the expandable peripheral side section in an alternative distribution status; each eyelet hole is arranged and distributed along the direction the periphery of the expandable peripheral side section extends;   at least one control draw cord, passing through the eyelet holes arranged at the two at least alternatively opposite side areas of the expandable peripheral side section and the bendable sections in an alternative manner; said control draw cord must have at least two positioning ends fixed at the two internal locations of the expandable peripheral side section;   two pull control and carry sections, formed by the sections between the two eyelet holes at the two opposite locations of the two control draw cords; the expandable peripheral side section at the vertically folded state could be pulled upwards through the two pull control and carry sections so that the expandable peripheral side section could be gathered together in a vertical frame enclosure body form; at the meanwhile, the two pull control and carry sections can be used by the user to carry the bag.   
     
     
         2 . The structure defined in  claim 1 , wherein the bearing plate section is in a rectangular planar shape; the expandable peripheral side section is in a form constituted by plate bodies; the expandable peripheral side section is connected with the periphery of the bearing plate section by a flexible connecting edge; the bendable sections in the tridentate pre-creased line form are arranged at the four corner regions of the expandable peripheral side section respectively, through which the expandable peripheral side section is divided the alternatively opposite two side plate sections and two end plate sections with different lengths and areas; through the bending change of each tridentate bendable section, the sections between the side plate sections and end plate sections could be made into a vertically folded state and gathered together to form a rectangular vertical frame enclosure body form; the control draw cords are two cords passing through the two side plate sections and the eyelet holes located at their adjacent two corner regions respectively; the two end plate sections are not provided with the eyelet holes; the two positioning ends of the control draw cord are fixed onto their two corner regions respectively; the section between the two eyelet holes provided for the two side plate sections constitutes said pull control and carry section. 
     
     
         3 . The structure defined in  claim 2 , wherein the two end plate sections are formed with the inverted V-shaped pre-creased lines so that the expandable peripheral side section can be made at a vertically folded state; and the upper ends of the two end plate sections could be closed and folded into a necking state. 
     
     
         4 . The structure defined in  claim 1 , wherein the expandable peripheral side section is in a form constituted by the flexible planar material; and said bendable section is in a non-neat creased form formed by utilizing the own flexibility of the expandable peripheral side section. 
     
     
         5 . The structure defined in  claim 3 , wherein the pull control and carry section is in a length form of the carrying belt or back strap type. 
     
     
         6 . The structure defined in  claim 5 , wherein the positioning ends of the control draw cord could be fixed onto the expandable peripheral side section by way of the sewn threads or the rope knotting. 
     
     
         7 . The structure defined in  claim 6 , wherein the surface of the bearing plate section is even provided with the game pattern; said game pattern includes any of the following kind: the checkerboard pattern and the Monopoly pattern. 
     
     
         8 . The structure defined in  claim 7 , wherein one location of the expandable peripheral side section is even be provided with an article containing bag to containing the articles. 
     
     
         9 . The structure defined in  claim 8 , wherein one side of the article containing bag could be connected to the edge of the expandable peripheral side section so that the containing bag could be lifted up and swung to the inner side or outer side of the expandable peripheral side section to meet the needs of various users. 
     
     
         10 . The structure defined in  claim 9 , wherein the back of the bearing plate section and the expandable peripheral side section is connected with an anti-slip layer.
