Closed container system

Abstract

A sealable container system made of biodegradable materials, including a generally cylindrical, inwardly sloping container body having flattened side portions with holes therein, and a generally cylindrical, inwardly sloping cap with outwardly projecting tabs that are received into the holes to secure the cap onto the container. Inward pressure preleases the tabs from the holes so the cap can be removed without twisting.

What is claimed is: 
     
         1 . A closed container system, comprising:
 a container body having a cylindrical, inwardly sloping shape; and   a cap receivable onto the container body, wherein the container body is made from biodegradable materials and the cap is made from plastic.   
     
     
         2 . The closed container system of  claim 1 , wherein the biodegradable material is molded pulp fiber and the plastic is standard class or bio-based. 
     
     
         3 . The closed container system of  claim 1 , wherein the container body has a top lip and the cap is received over the lip. 
     
     
         4 . The closed container system of  claim 3 , wherein the cap has a bottom rim that encircles the top lip of the cap when the cap is received over the lip. 
     
     
         5 . The closed container system of  claim 4 , wherein the lip of the container body has a notch formed therein and the bottom rim of the cap has an inwardly facing protrusion formed thereon, and wherein the inwardly facing protrusion on the bottom rim passes through the notch on the lip when the cap is received over the lip. 
     
     
         6 . The closed container system of  claim 5 , wherein rotation of the cap after the cap has been received over the lip locks the inwardly facing protrusion underneath the top lip of the container body. 
     
     
         7 . The closed container system of  claim 1 , wherein the container body has an open top end and is dimensioned to nest within an identical container body. 
     
     
         8 . A closed container system, comprising:
 a container body having a cylindrical, inwardly sloping shape; and   a cap receivable onto the container body, wherein the container body and the cap are made from biodegradable materials.   
     
     
         9 . The closed container system of  claim 8 , wherein the biodegradable material is molded pulp fiber or plant-based material. 
     
     
         10 . The closed container system of  claim 8 , wherein the biodegradable material is bio-plastic. 
     
     
         11 . The closed container system of  claim 8 , wherein the container body has a top lip and the cap is received over the lip. 
     
     
         12 . The closed container system of  claim 11 , wherein the cap has a bottom rim that encircles the top lip of the cap when the cap is received over the lip. 
     
     
         13 . The closed container system of  claim 12 , wherein the lip of the container body has a notch formed therein and the bottom rim of the cap has an inwardly facing protrusion formed thereon, and wherein the inwardly facing protrusion on the bottom rim passes through the notch on the lip when the cap is received over the lip. 
     
     
         14 . The closed container system of  claim 13 , wherein rotation of the cap after the cap has been received over the lip locks the inwardly facing protrusion underneath the top lip of the container body. 
     
     
         15 . The closed container system of  claim 8 , wherein the container body has an open top end and is dimensioned to nest within an identical container body.
