<p>#CMT# #/CMT# The container (1) has a bottom (8) extended at an end of the container. The bottom has a deformable annular membrane (11) in the form of a spherical cap and extended from an annular step (10) perpendicular to a cylindrical body. The step is extended from an annular base (9) towards interior of the container. A pin (12) is extended in projection at the center of the bottom towards the interior of the container and in an extension of the membrane. The membrane, step, base and a lateral wall of the pin are made of crystalline. An amorphous pellet is located at the center of top of the pin. #CMT#USE : #/CMT# Plastic container e.g. polyethylene terephthalate (PET) pot or bottle such as wide neck PET bottle. #CMT#ADVANTAGE : #/CMT# The amorphous pellet is located at the center of the top of the pin, and the membrane, step, base and the lateral wall of the pin are made of crystalline, thus reducing the non controlled deformation of the bottom of the container during hot-filling of liquid. The container has improved aesthetic and mechanical properties. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a plastic container. 1 : Container 8 : Bottom 9 : Annular base 10 : Annular step 11 : Annular membrane 12 : Pin.</p> |
