Container Cap

Abstract

An aspect of the invention provides a container cap. The container cap comprises a cap, a handling outer portion, and connecting walls. The cap has a closed end and an open end. The handling outer portion encloses the cap and including recesses and a plurality of protrusions. The plurality of connecting walls connect an outer wall of the cap and an inner wall of the handling outer portion, wherein the connecting walls are disposed radially. The voids are provided between the outer wall of the cap, the inner wall of the holding outer portion, and the connecting walls.

 a cap having a closed end and an open end;   a handling outer portion enclosing the cap and including a plurality of recesses and a plurality of protrusions, wherein an innermost portion of each of the plurality of recesses is disposed away from an outer wall of the cap and therefore does not make a contact with the cap except through one or more of connecting walls,   wherein each connecting wall connects the outer wall of the cap and an inner wall of the handling outer portion, wherein each of the connecting walls is disposed radially,   wherein a plurality of voids are provided between the outer wall of the cap, the inner wall of the holding outer portion, and the connecting walls.   
     
     
         2 . The container cap of  claim 1 , further comprising a female thread provided on inner wall of the cap, wherein the cap and the female thread are configured to fit into and seal an opening of a container. 
     
     
         3 . The container cap of  claim 2 , wherein the female thread is configured to fit to a male thread of the opening of a container. 
     
     
         4 . The container cap of  claim 3 , further comprising a safety seal provided at the open end of the cap, wherein the safety seal is configured to hold the opening of the container in place for a twisting force below a predetermined magnitude and break for a twisting force above the predetermined magnitude. 
     
     
         5 . The container cap of  claim 1 , wherein the handling outer portion comprises three or more recesses and three or more protrusions, wherein the recesses and the protrusions are disposed alternatingly. 
     
     
         6 . The container cap of  claim 5 , wherein the recesses and the protrusions form a circular shape with six indentations, wherein the circular shape forms an overall appearance of a shape of six petal flower. 
     
     
         7 . The container cap of  claim 6 , wherein three connecting walls extend radially from inner walls of three every other recesses. 
     
     
         8 . The container cap of  claim 7 , wherein each of the connecting walls extends vertically from a first position below a top edge of the handling outer portion by a first predetermined distance to a second position above a bottom edge of the handling outer portion by a second predetermined distance. 
     
     
         9 . The container cap of  claim 1 , wherein at least one of the recesses comprises one or more first through-holes. 
     
     
         10 . The container cap of  claim 1 , wherein at least one of the protrusions comprises one or more second through-holes. 
     
     
         11 . The container cap of  claim 10 , wherein one of the through-holes has a shape of circle. 
     
     
         12 . The container cap of  claim 1 , wherein one of the connecting walls comprises one or more third through-holes. 
     
     
         13 . The container cap of  claim 12 , wherein the third through-hole has a shape of circle. 
     
     
         14 . The container cap of  claim 1 , wherein the cap, the handling outer portion, and the plurality of connecting walls are formed integrally. 
     
     
         15 . The container cap of  claim 14 , wherein the safety seal is formed integrally. 
     
     
         16 . The container cap of  claim 15 , wherein the safety seal protrudes below a plane defined by the lower end of the handling outer portion. 
     
     
         17 . The container cap of  claim 1 , wherein the cap is cylindrical. 
     
     
         18 . The container cap of  claim 1 , wherein a gap is provided between the lower side of the cap and the upper side of the safety seal in which an abutment flange of a container fits in. 
     
     
         19 . The container cap of  claim 18 , wherein the inner safety seal wall is configured to engage at least one protrusion of the container. 
     
     
         20 . The container cap of  claim 19 , wherein the outer diameter of the abutment flange between the lower wall of the cap and the upper wall of the safety seal is larger than the inner diameter of the safety seal.
