Plastic Bottle and Similar Containers Made Of Plastic

Abstract

A plastic bottle ( 1 ) and similar containers for receiving fluid substances have an elongated body ( 2 ), wherein the one longitudinal end is closed by a bottom ( 3 ) and the opposite end transitions into a neck section ( 4 ) having a pouring spout ( 5 ). A shoulder section ( 6 ) extends from the neck section ( 4 ) to a region ( 7 ) of the body ( 2 ), wherein the region has a larger diameter. The shoulder section ( 6 ) is equipped with structured regions ( 10 ) at least in a portion of the axial and circumferential extensions thereof.

1 . A plastic bottle and similar containers to hold fluid substances, comprising:
 an elongated body, one longitudinal end of which is closed by a bottom and the opposite end of which transitions to a neck section with a pour opening, said body having a shoulder section that extends from the neck section to an enlarged diameter area of the body, and the shoulder section being provided with structuring in at least a portion of its axial extent and along its circumference; and   two or more rings of geometric base structures located in the shoulder section, said rings being separated from one another by transverse or longitudinal grooves.   
   
   
       2 . The plastic bottle according to  claim 1 , characterized in that the structuring is arranged evenly along the circumference of the shoulder section and comprises repeating, annular geometric base structures. 
   
   
       3 . The plastic bottle according to  claim 1 , wherein the two or more rings of geometric base structures are separated from one another by grooves that run essentially in the longitudinal direction of the body. 
   
   
       4 . The plastic bottle according to  claim 3 , wherein the grooves that run essentially in the longitudinal direction are located in a projection view parallel to the longitudinal axis of the body. 
   
   
       5 . (canceled) 
   
   
       6 . The plastic bottle according to  claim 4 , wherein the grooves that run in the longitudinal direction form an included angle of up to 45 degrees with the longitudinal axis of the body in a projection view. 
   
   
       7 . A The plastic bottle according to  claim 1 , wherein the transverse and/or longitudinal grooves have a depth of about 0.5 mm to about 1.5 mm. 
   
   
       8 . The plastic bottle according to  claim 7 , wherein the transverse and/or longitudinal grooves comprise a notched base whose width measured perpendicular to the groove's length is about 0.2 mm to about 1.2 mm. 
   
   
       9 . The plastic bottle according to  claim 1 , wherein walls of the transverse and/or longitudinal grooves form an opening angle together of about 50° to about 100°. 
   
   
       10 . The plastic bottle according to  claim 9 , wherein the structuring located in rings comprises 9 to 15 geometric base structures ( 13 ,  14 ) that are arranged evenly along the circumference. 
   
   
       11 . The plastic bottle according to  claim 10 , wherein two or more rings of geometric base structures are arranged in the shoulder section, wherein each ring has the same number of geometric base structures separated from one another by longitudinal grooves that extend across adjacent ring structures. 
   
   
       12 . The plastic bottle according to  claim 1 , wherein the geometric base structures are designed rectangular to trapezoidal. 
   
   
       13 . The plastic bottle according to  claim 12 , wherein the base structures have a height that is 1 to 1.5 times their width. 
   
   
       14 . The plastic bottle according to  claim 1 , wherein it has a fill volume of 50 ml to 330 ml. 
   
   
       15 . A The plastic bottle according to  claim 1 , wherein the structuring in the shoulder section is produced in a stretch-blowing or extrusion blowing process within the mold cavity of a blow mold.
