Container for flowable product e.g., beverage and mineral water, includes walls made of flexible plastic that can be deformed for constant surface area, particularly under weight of flowable product

摘要

A container includes walls made of flexible plastic that can be deformed for constant surface area, particularly under the weight of the flowable product contained in the container when the wall(s) encounter a point or bearing surface to form non-planar wall portion. A container comprises a body (1) with greater section of dimension (d1) and neck (2) with internal diameter (d2). It may be closed by a closing-off member (3) and may be distributed with flowable product. The wall(s) (4) forming the body of the container is made of flexible plastic which can be deformed for constant surface area, particularly under the weight of the flowable product contained in the container when the wall(s) encounter a point or bearing surface, so as to form, non-planar wall portion (5). The ratio of d2 on d1 is 1:3-1:10. An Independent claim is also included for a method of manufacturing a body of a container where the body is obtained by stretch blow molding of a polyethylene terephthalate preform suited to making the container with a stretch ratio of 20-50, preferably 25-35.
