Closure Cap For A Detergent Bottle

Abstract

A closure cap for a detergent bottle, the closure cap including at least one cap wall having a plurality of surface elements spaced apart from one another. The surface elements each have a circumferential edge, starting from which the particular surface element extends from a datum plane of the cap wall, and which surrounds a base of the surface element located in the datum plane of the cap wall. In order to form a smooth transition from the datum plane that does not have a notch effect, a radius of curvature is provided at the circumferential edge that is larger than the largest longitudinal extent of the base of the surface element.

What is claimed is: 
     
         1 . A closure cap for a detergent bottle, the closure cap comprising at least one cap wall having a plurality of surface elements spaced apart from one another, each having a circumferential edge, starting from which the particular surface element extends from a datum plane of the cap wall, and which surrounds a base of the surface element located in the datum plane of the cap wall, wherein, in order to form a smooth transition from the datum plane, a radius of curvature is provided at the circumferential edge, which radius of curvature is larger than the largest longitudinal extent of the base of the surface element. 
     
     
         2 . The closure cap according to  claim 1 , wherein the base of the surface element is circular. 
     
     
         3 . The closure cap according to  claim 1 , wherein the surface element is designed as an outwardly directed raised surface portion. 
     
     
         4 . The closure cap according to  claim 3 , wherein the raised surface portion is formed in one piece with the cap wall and is made of the same material as the cap wall. 
     
     
         5 . The closure cap according to  claim 1 , wherein the radius of curvature is at least twice as large as the largest longitudinal extent of the base of the surface element. 
     
     
         6 . The closure cap according to  claim 1 , wherein the largest height or largest depth of the surface element is less than one tenth of the largest longitudinal extent of the base of the surface element. 
     
     
         7 . The closure cap according to  claim 6 , wherein the largest height or largest depth of the surface element is less than one tenth of the smallest longitudinal extent of the base of the surface element. 
     
     
         8 . The closure cap according to  claim 1 , wherein the cap wall is a cylindrical or conical lateral face, the surface elements being arranged over the entire circumference of the lateral face. 
     
     
         9 . The closure cap according to  claim 7 , wherein the number of surface elements varies in the circumferential direction of the lateral face. 
     
     
         10 . The closure cap according to  claim 1 , wherein an internal thread is provided for screwing onto the detergent bottle. 
     
     
         11 . The closure cap according to  claim 1 , characterized by a seal made of a material that is softer than the material of the cap wall.
