Plastic containers for carbonated liquids

Abstract

Provided is a plastic container for receiving liquids, comprising a base area, a main body adjoining to said base area in a longitudinal direction of the container, a shoulder area adjoining to said main body in the longitudinal direction of said container, and a mouth area adjoining to said shoulder area in the longitudinal direction of said container, said mouth area having a container mouth. The container has a gripping area provided between said main body and said container mouth in the longitudinal direction of said container. The external cross section of said gripping area is smaller than an average external cross section of said shoulder area.

What is claimed is: 
     
         1 . A plastic container for receiving liquids, comprising:
 a base area;   a main body adjoining said base area, the main body extending in a longitudinal direction of the container;   a shoulder area adjoining said main body in the longitudinal direction of said container;   a mouth area adjoining said shoulder area in the longitudinal direction of said container, said mouth area including a container mouth; and   a gripping area between said main body and said container mouth along the longitudinal direction of said container, the gripping area having an external cross section that is smaller than a mean external cross section of said shoulder area.   
     
     
         2 . The plastic container as claimed in  claim 1 , wherein the gripping area has a smaller external cross section than that of the shoulder area. 
     
     
         3 . The plastic container as claimed in  claim 1 , wherein said gripping area has a structured surface constructed and arranged at least in sections. 
     
     
         4 . The plastic container as claimed in  claim 1 , wherein said gripping area is positioned between said shoulder area and said mouth area in the longitudinal direction of said container. 
     
     
         5 . The plastic container as claimed in  claim 1 , wherein a bead area is positioned between said gripping area and said mouth area. 
     
     
         6 . The plastic container as claimed in  claim 5 , wherein said bead area has a larger external cross section than that of said gripping area. 
     
     
         7 . The plastic container as claimed in  claim 5 , wherein a wall of said bead area has at least one indentation at a circumferential position at said bead area. 
     
     
         8 . The plastic container as claimed in  claim 1 , wherein an external diameter of said gripping area is less than 50 mm. 
     
     
         9 . The plastic container as claimed in  claim 8 , wherein an external diameter of said gripping area is less than 45 mm. 
     
     
         10 . The plastic container as claimed in  claim 8 , wherein an external diameter of said gripping area is less than 40 mm. 
     
     
         11 . The plastic container as claimed in  claim 1 , wherein said main body has a concave wall section. 
     
     
         12 . The plastic container as claimed in  claim 1 , wherein said plastic container has a wall thickness that varies in the longitudinal direction of said container. 
     
     
         13 . The plastic container as claimed in  claim 1 , wherein a base height of said base area is at least 40%, of the diameter of said base area. 
     
     
         14 . The plastic container as claimed in  claim 1 , wherein the plastic container is at least partially filled with at least one of a carbonated beverage or a liquid in a heated state. 
     
     
         15 . A method, comprising:
 providing a main body, a base area, a shoulder area, a mouth area, and a gripping area of a plastic container that extend along a longitudinal direction, said gripping area between said mouth area and said shoulder area, said main body between said shoulder area and said base area, said mouth area including a container mouth;   constructing and arranging said gripping area to have an external cross section that is smaller than a mean external cross section of said shoulder area; and   inputting a liquid to said container mouth to at least partially fill said plastic container from said base area to said mouth area.   
     
     
         16 . The method as claimed in  claim 15 , further comprising:
 inputting a gaseous or liquid medium to said plastic container via said container mouth.   
     
     
         17 . The method as claimed in  claim 16 , further comprising:
 sealing said plastic container at said container mouth after filling the plastic container with the liquid and inputting the gaseous or liquid medium to said plastic container.   
     
     
         18 . The method as claimed in  claim 15 , wherein the inputted liquid is in a heated state. 
     
     
         19 . The method as claimed in  claim 15 , further comprising:
 positioning a bead area between said gripping area and said mouth area.   
     
     
         20 . The method as claimed in  claim 19 , wherein said bead area has a larger external cross section than said gripping area.
