Multilayer Container Structure

Abstract

The present invention is related to a multilayer container structure including a first container, at its first opening circumference having a first connecting part on which first and second securing slots are provided at upper and lower location respectively, a second container, at its second opening circumference having a second connecting part and a snap slot inside a storing room, and a lid, provided with a protrusion, a third connecting part at its periphery and a plurality of first protrusive snap latch besides the protrusion. Thereby the second connecting part of the second container can attach to the first securing slot of the first container for placing the former inside the later. The third connecting part of the lid can attach to either the second securing slot of the first container or the snap slot of the second container for placing it above the lid.

I claim: 
     
         1 . A multilayer container structure comprising:
 a first container provided with a first storing room and a first opening together with a first connecting part as extended from the first opening circumference outward and upward, a first securing slot as positioned at the first connecting part adjacent to the first opening and a second securing slot as positioned at the first connecting part away from the first opening and above the first securing slot;   at least a second container connectively covering the first opening of said first container as positioned within the first storing room while provided with a second storing room and a second opening together with a second connecting part as extended from the second opening circumference outward for attaching to the first securing slot of said first container into a secure form; and   a lid attached to the first opening of said first container as laying above the second opening of said second container and provided with a protrusion, a first extension as horizontally extended from a side of the protrusion outward, a third connecting part vertically positioned at the first extension periphery for attaching to the second securing slot of said first container.   
     
     
         2 . The multilayer container structure of  claim 1 , wherein said lid further includes a second extension as horizontally extended from the third connecting part circumference outward with at least two protrusions provided at the second extension circumference. 
     
     
         3 . A multilayer container structure comprising:
 a first container provided with a first storing room and a first opening together with a first connecting part as extended from the first opening circumference outward and upward, a first securing slot as positioned at the first connecting part adjacent to the first opening and a second securing slot as positioned at the first connecting part away from the first opening and above the first securing slot;   a lid attached to the first opening of said first container and provided with a protrusion, a plurality of first snap latch provided in a protrusive form at one side of the protrusion, a first extension horizontally extended outward from the other side of the protrusion, and a third connecting part longitudinally provided at the first extension periphery for attaching to the second securing slot of said first container while constituting a groove between the protrusion;   at least a second container attached to the protrusion of said lid and provided with a second storing room and a second opening that a snap slot provided in a recess form at an inner wall of the second storing room of said second container while said second container able to lay above the protrusion of said lid that the snap slot able to securely attach to the plurality of the first snap latch.   
     
     
         4 . The multilayer container structure of  claim 3 , wherein a plurality of second snap latch is provided at an outer wall of the second storing room of said second container for engaging the snap slot of another second container thereby said second container can be stacking up in a secure form. 
     
     
         5 . The multilayer container structure of  claim 3 , wherein a second extension is provided at the third connecting part periphery of said lid as horizontally extended outward and at least two protrusions are provided at the second extension periphery.
