Abstract

A flattened bottle comprising a neck, a shoulder, a body and a bottom;

said body having an upper body section, a lower body section and a middle body section, said upper body section and said lower body section showing a substantially rectangular cross section with quadrant corners;

said middle body section showing an elliptic cross section and having inwardly deformable front and rear walls and inwardly curved side walls, said side walls being adapted to be deformed outwardly corresponding to any inward deformation of the front and rear walls due to pressure reduction.

Claims

1. A flattened bottle comprising a neck, a shoulder connected to the neck, a body and a bottom;

said body having an upper body section connected to the shoulder, a lower body section connected to the bottom and a middle body section connected to the upper body section at an upper edge and connected to the lower body section at a lower edge;

said upper body section and said lower body section showing a substantially rectangular cross section with quadrant corners;

said middle body section showing a geometrically elliptic cross section and having inwardly deformable front and rear walls and side walls curving inwardly from said upper and lower edges,

said side walls deforming outwardly in response to inward deformation of the front and rear walls due to pressure reduction inside said middle body section.

2. A flattened bottle according to claim 1, wherein

side walls remain within vertical planes between the upper and lower edges along the side walls when the side walls are deformed.

3. A flattened bottle according to claim 1, wherein

each of the front and rear walls of the middle body section includes a plurality of horizontally extending ribs.
