Abstract

An embossed head for an end of a tank is disclosed. The embossed head can include one or more embossed features. The embossed feature(s) can extend generally upward or generally downward. The embossed features(s) can include an annular emboss. The embossed head can provide similar resistance to deformation as traditional heads while requiring less material as compared to such traditional heads

Claims

exact text as granted — not AI-modified
1 . A tank head comprising:
 a skirt portion extending at least partially in an axial direction relative to a central axis of the tank head;   a knuckle portion configured to transition between the skirt portion and a transition portion of the tank head, the knuckle portion extending at least partially in a radial direction relative to the central axis of the tank head;   the transition portion configured to transition between the knuckle portion and a central portion of the tank head; and   one or more embossed features, each having a side wall that extends at least partially in the axial direction.   
     
     
         2 . The tank head of  claim 1 , wherein the tank head has a constant material thickness. 
     
     
         3 . The tank head of  claim 1 , wherein the one or more embossed features comprises an annular emboss. 
     
     
         4 . The tank head of  claim 3 , wherein the annular emboss extends at least partially in the radial direction such that the annular emboss is sloped. 
     
     
         5 . The tank head of  claim 1 , wherein the one or more embossed features comprises a plurality of separate and distinct embosses. 
     
     
         6 . The tank head of  claim 1 , wherein an embossed feature of the one or more embossed features extends in a generally direction. 
     
     
         7 . The tank head of  claim 1 , wherein an embossed feature of the one or more embossed features extends in an upward direction. 
     
     
         8 . The tank head of  claim 1 , wherein the one or more embossed features comprises:
 a first plurality of embosses, each having a first shape and a first size; and   a second plurality of embosses, each having a second shape and a second size,   wherein at least one of:   the second shape is different from the first shape, or   the second size is different from the first size.   
     
     
         9 . The tank head of  claim 8 , wherein:
 each of the first plurality of embosses is located along a first circumference corresponding to a first radius extending from the central axis of the tank head, and   each of the second plurality of embosses is located along a second circumference corresponding to a second radius extending from the central axis of the tank head, the second radius being greater than the first radius.   
     
     
         10 . The tank head of  claim 1 , further comprising a secondary emboss located at least partially within an embossed feature of the one or more embossed features. 
     
     
         11 . The tank head of  claim 1 , wherein the one or more embossed features comprise a first embossed feature proximate to the skirt portion, wherein the one or more embossed features comprise a first embossed feature of the skirt portion, wherein the one or more embossed features comprise a first embossed feature proximate to the knuckle portion, wherein the one or more embossed features comprise a first embossed feature of the knuckle portion, wherein the one or more embossed features comprise a first embossed feature proximate to the transition portion, or wherein the one or more embossed features comprise a first embossed feature of the transition portion. 
     
     
         12 - 16 . (canceled) 
     
     
         17 . A fluid heating tank comprising a tank head, the tank head comprising:
 a skirt portion extending at least partially in an axial direction relative to a central axis of the tank head;   a knuckle portion configured to transition between the skirt portion and a transition portion of the tank head, the knuckle portion extending at least partially in a radial direction relative to the central axis of the tank head;   the transition portion configured to transition between the knuckle portion and a central portion of the tank head; and   one or more embossed features, each having a side wall that extends at least partially in the axial direction.   
     
     
         18 . The fluid heating tank of  claim 17 , wherein the one or more embossed features comprises an annular emboss. 
     
     
         19 . The fluid heating tank of  claim 18 , wherein the annular emboss extends at least partially in the radial direction such that the annular emboss is sloped. 
     
     
         20 . The fluid heating tank of  claim 17 , wherein the one or more embossed features comprises a plurality of separate and distinct embosses. 
     
     
         21 . The fluid heating tank of  claim 17 , wherein the one or more embossed features comprises:
 a first plurality of embosses, each having a first shape and a first size; and   a second plurality of embosses, each having a second shape and a second size,   wherein at least one of:   the second shape is different from the first shape, or   the second size is different from the first shape.   
     
     
         22 . The fluid heating tank of  claim 17 , further comprising a secondary emboss located at least partially within an embossed feature of the one or more embossed features. 
     
     
         23 . The fluid heating tank of  claim 17 , wherein the one or more embossed features comprise a first embossed feature proximate to the skirt portion. 
     
     
         24 . A tank head comprising:
 a first portion extending at least partially in an axial direction relative to a central axis of the tank head;   a second portion configured to transition between the first portion and a third portion of the tank head, the second portion extending at least partially in a radial direction relative to the central axis of the tank head;   the third portion configured to transition between the second portion and a fourth portion of the tank head; and   one or more embossed features of or in between at least one of the first portion, the second portion, the third portion, and the fourth portion.   
     
     
         25 . The tank head of  claim 19 , wherein the one or more embossed features comprises an annular emboss.
