Container with surface features

Abstract

A container, and method of producing thereof, wherein the container comprises an internal reservoir, an inner wall having an opening extending into the internal reservoir, and an outer wall. A vacuum-sealed cavity is enclosed by the inner wall and outer wall. One or more surface features may be formed in an outer surface of the outer wall, wherein at least one of the surface features is produced by a subtractive manufacturing process and/or configured to perform as a damper/friction member.

What is claimed is: 
     
         1 . A container, comprising:
 at least one wall defining an interior reservoir; and   a plurality of surface features provided on an outer surface of the at least one wall,
 wherein each of the surface features is axially spaced apart from one another. 
   
     
     
         2 . The container of  claim 1 , wherein at least one of the surface features continuously extends around a circumference of the container. 
     
     
         3 . The container of  claim 1 , wherein at least one of the surface features is formed with interruptions to be discontinuous. 
     
     
         4 . The container of  claim 1 , wherein at least one of the surface features is a groove formed in the outer surface of the at least one wall. 
     
     
         5 . The container of  claim 1 , wherein at least one of the surface features is a void in a coating treatment in a specific area and/or pattern. 
     
     
         6 . The container of  claim 1 , wherein the plurality of surface features comprises a first surface feature axially spaced from a closed end of the container by about 60 mm, a second surface feature is spaced from the closed end of the container by about 48 mm, and/or a third surface feature is spaced from the closed end of the container by about 36 mm. 
     
     
         7 . The container of  claim 1 , wherein at least one of the surface features is spaced apart from another one of the surface features by a substantially equal distance. 
     
     
         8 . The container of  claim 1 , wherein a spacing between two or more of the surface features varies. 
     
     
         9 . The container of  claim 1 , wherein a thickness of two or more of the surface features varies from one another. 
     
     
         10 . The container of  claim 1 , wherein the plurality of surface features comprises a first surface feature having a thickness of about 0.3 mm, a second surface feature having a thickness of about 1.1 mm, and/or a third surface feature has a thickness of about 1.9 mm. 
     
     
         11 . The container of  claim 1 , wherein a thickness of at least one of the surface features varies around a circumference of the container. 
     
     
         12 . The container of  claim 1 , wherein one of the surface features is disposed at a bottom of the container and is a damper/friction member. 
     
     
         13 . A method of producing a container, comprising:
 forming at least one wall to define an interior reservoir; and   providing a plurality of surface features on an outer surface of the at least one wall,
 wherein each of the surface features is axially spaced apart from one another. 
   
     
     
         14 . The method of  claim 13 , wherein at least one of the surface features is formed by a subtractive manufacturing process. 
     
     
         15 . The method of  claim 13 , wherein at least one of the surface features is formed during a coating process of the container. 
     
     
         16 . The method of  claim 13 , wherein two or more of the surface features are independently formed from one another. 
     
     
         17 . The method of  claim 13 , wherein two or more of the surface features are formed substantially simultaneously in the container. 
     
     
         18 . The method of  claim 13 , further comprising using a grid system for alignment of at least one of the surface features. 
     
     
         19 . The method of  claim 18 , wherein the grid system employs a uniform square grid. 
     
     
         20 . The method of  claim 18 , wherein the grid system is relative to a closed end of the container.
