Embodiment Construction

[0057] Hereinafter, for ease of understanding, the terms 'lower', 'upper', 'top', 'bottom' and the like are used with reference to the accompanying drawings. They should however not be considered as limiting the scope of the invention.

[0058] refer to Figure 2 to Figure 6 Preferred embodiments of the present invention are described. Figure 1A to Figure 1D Shown is a container bottom according to the prior art.

[0059] figure 2 The bottom 30 of the container according to the invention is shown.

[0060] exist image 3 with 4 A bottom view of the bottom 30 is shown in .

[0061] The bottom 30 may be obtained by moulding, as known to those skilled in the art.

[0062] The bottom 30 comprises ribs 70, referred to as main ribs 70, each in the form of an outwardly extending groove, the main ribs extending in a substantially radial direction and passing through an annular region forming the substantially flat base 50, The base 50 allows the base to rest firmly on a flat ...

Abstract

The present invention relates to a container made of thermoplastic material comprising a body extending between a neck and a bottom capable of withstanding without significant deformation the hydrostatic pressure caused by the column of liquid contained in the container, the pressure of the column of liquid Increased by no more than 2x105Pa, the bottom includes main ribs (70) in the form of outwardly facing grooves and extending substantially radially through an annular region forming a substantially flat base (50) by which (50), the bottom can rest firmly on a flat support, and main ribs (70) extend upwardly on the wall (80) connecting the bottom to the container body. The container has a shoulder (90) forming a junction area between the connecting wall (80) and the container body, and the main rib (70) extends upwardly beyond the shoulder (90).

Description

technical field [0001] The present invention relates to improvements in the bottom of containers, in particular bottles made of thermoplastic material such as PET, having a body extending between a neck at the upper end and a bottom at the lower end and capable of The case withstands significant deformation due to an increase of not more than about 2x10 5 The hydrostatic pressure of a liquid column of Pa pressure. Background technique [0002] In most cases, containers for non-carbonated liquids (for example, bottles for still water) have a convexly rounded bottom, usually an outwardly concave spherical end cap with a small height. [0003] Such bases usually have ribs extending substantially radially and distributed around the central reinforcement. These ribs can have a variety of configurations, some can extend beyond the bottom of the wall of the body, thereby strengthening the base (making the bottom a peripheral area on the support). [0004] The height of this type...
