System and method for attaching an exchangeable sealing caps to containers

Abstract

Systems for containing solid or liquid foodstuff are disclosed. An aspect of the system comprises a container configured to store the solid or liquid foodstuff. The container comprises an integral head coupler on its upper surface. The system also comprises a detachable head cap comprising an integral bottle coupler on its lower surface. The head coupler is configured to engage directly with the bottle coupler for mechanically connecting the detachable head cap to the container to seal the foodstuff thereof. The head coupler is configured to mechanically connect different head caps to the container. Optionally, the function of the detachable head cap is performed by two separate elements, a detachable head and a sealing cap.

What is claimed is: 
     
         1 . A container system configured to contain solid or liquid foodstuff, the container comprising:
 a container configured to store the solid or liquid foodstuff, wherein the container comprises an integral head coupler on its upper surface; and   a detachable head cap comprising an integral bottle coupler on its lower surface, wherein the detachable head cap comprises a stress relief element.   
     
     
         2 . The container system of  claim 1  wherein the stress relief element is configured to relieve stress by providing tactile feedback to a user. 
     
     
         3 . The container system of  claim 1  wherein the head section is configured to be detachable from the bottle section such that the stress relief element may be used by a user drinking from the container. 
     
     
         4 . The container system of  claim 1  wherein the stress relief element comprises a soft material section. 
     
     
         5 . The container system of  claim 1  wherein the stress relief element comprises a soft flexible plastic section. 
     
     
         6 . The container system of  claim 1  wherein the stress relief element comprises a rubber material configured to be pressed. 
     
     
         7 . The container system of  claim 1  wherein the stress relief element comprises a spring mechanism configured to be depressed by a finger and further configured to expand upon release. 
     
     
         8 . The container system of  claim 1  wherein the stress relief element comprises a mechanical clicker. 
     
     
         9 . The container system of  claim 1  wherein the stress relief element comprises a fidget switch. 
     
     
         10 . The container system of  claim 1  wherein the stress relief element comprises a stress ball. 
     
     
         11 . The container system of  claim 1  wherein the stress relief element comprises a mechanical clicker. 
     
     
         12 . The container system of  claim 1 , wherein the head coupler is configured to mechanically connect different head caps to the container. 
     
     
         13 . The container system of  claim 1 , wherein a coupling mechanism for connecting head coupler to the bottle coupler comprises one or more of a screw thread mechanism, male-female push connectors, non-binary connectors, clips, studs, fasteners, magnetic pins, vacuum seals, hook-and-eye connectors, high friction surfaces and combinations thereof. 
     
     
         14 . The container system of  claim 1 , wherein the detachable head cap is formed from an odorless or pleasant odor material. 
     
     
         15 . The container system of  claim 1  further comprises a gripping ring configured for tightening grip between the bottle coupler and the head coupler. 
     
     
         16 . The container system of  claim 1 , wherein the detachable head cap resembles the shape of a living or a non-living being. 
     
     
         17 . The container system of  claim 1 , wherein the detachable head cap further comprises a closable drinking aperture for easy access to the foodstuff stored within the container. 
     
     
         18 . The container system of  claim 17 , wherein the closable drinking aperture comprises a sipper aperture section, a drinking straw section or a combination thereof. 
     
     
         19 . The container system of  claim 1 , wherein the detachable head cap further comprises a carrying handle configured for easy carrying the container system. 
     
     
         20 . A container system of  claim 1  further comprising a sealing cap configured to form a watertight seal for the container wherein the detachable head cap is configured to connect with the sealing cap.
