Expandable container

Abstract

Traditional structured-containers have a maximum holding capacity upon exceeding of which would allow excess articles fall out of the structured-container by way of gravitational pull. The utility of these structured-containers is thus limited. The present invention discloses an expandable container with a pair of carry-handles where a net container is coupled to a traditional structured-container to thus synergistically and substantially increase the maximum holding capacity of the traditional structured-container. The pair of carry-handles also adds carrying possibilities and conveniences.

       8 . The expandable container with a pair of carry-handles of  claim 6 , wherein the body and the plate of each of the top fastener and the bottom fastener are spring biased with a biasing force to push the body away from the plate to prevent the first and second plate holes to be correspondingly concentric with the first and second body holes. 
   
   
       9 . The expandable container with a pair of carry-handles of  claim 8 , wherein the first and second body holes are correspondingly concentric with the first and second plate holes by pushing the plate toward the main body against the biasing force of the spring. 
   
   
       10 . A method of making a net container, comprising a plurality of steps of:
 a) fold a top region of a sheet of rectangular net material along a top fold line to form a top double layer;   b) fold a bottom region of the sheet of rectangular net material along a bottom fold line to form a bottom double layer;   c) affix the top double layer and affix the bottom double layer to correspondingly create a top channel and a bottom channel;   d) create a top entry hole and a top exit hole on the top channel;   e) create a bottom entry hole and a bottom exit hole on the bottom channel;   f) fold a left region of the sheet of rectangular net material along a left fold line to form a left double layer;   g) fold a right region of the sheet of rectangular net material along a right fold line to form a right double layer;   h) overlap the left double layer with the right double layer;   i) affix the left double layer to the right double layer;   j) insert a leading end of a top restrainer into the top entry hole;   k) insert the leading end of the top restrainer out of the top exit hole so the leading end and a trailing end of the top restrainer are outside the top channel;   l) insert the leading end of the top restrainer into a first pair of top concentric holes of a top fastener device when a first body hole of a top main body is concentrically aligned with a first plate hole of a top plate;   m 1 ) insert the trailing end of the top restrainer into a second pair of top concentric holes of the top fastener device when a second body hole of the top main body is concentrically aligned with a second plate hole of the top plate;   m 2 ) attach a pair of carry-handles to the rectangular net material.   
   
   
       11 . The method of  claim 10 , further including a step of:
 n) insert a leading end of a bottom restrainer into the bottom entry hole.   
   
   
       12 . The method of  claim 11 , further including a step of:
 o) insert the leading end of the bottom restrainer out of the bottom exit hole so the leading end and a trailing end of the bottom restrainer are outside the bottom channel.   
   
   
       13 . The method of  claim 12 , further including a step of:
 p) insert a leading end of a bottom restrainer into a first pair of bottom concentric holes of a bottom fastener device when a first bottom body hole of a bottom main body is concentrically aligned with a first bottom plate hole of a bottom plate.   
   
   
       14 . The method of  claim 13 , further including a step of:
 q) insert a trailing end of a bottom restrainer into a second pair of bottom concentric holes of the bottom fastener device when a second bottom body hole of the bottom main body is concentrically aligned with a second bottom plate hole of the bottom plate.

 s) adjust the second restrainer through any of the first and second pair of bottom concentric holes to one of a desired opening size and closure size over a bottom end of the net container.   
   
   
       17 . The method of  claim 10 , wherein the top main body is spring biased with a biasing force against the top plate so as to prevent the formation of the first and second pair of top concentric holes; and
 wherein the first and second pair of top concentric holes are formed when the top plate is pressed toward the top main body against the biasing force of the spring.   
   
   
       18 . The method of  claim 17 , wherein the first and second pair of top concentric holes are formed when the top plate is pressed toward the top main body against the biasing force of the spring.
