Problems solved by technology

This higher deformability of such wide-mouth short necks can lead to disadvantageous leakage problems when the container is hermetically closed by a removable closure that is screwed onto the wide-mouth container to Such that a seal is achieved between the closure and only the top of the container neck without any seal between the closure and the inner face or lower portion of the container neck

Embodiment Construction

[0030] Some preferred embodiments of the invention are discussed in detail below. While specific exemplary embodiments are discussed, it should be understood that this is done by way of example only. Those skilled in the art will recognize that other container designs or container dimensions may be used without departing from the spirit and scope of the invention.

[0031] Referring now to the accompanying drawings, figure 1 A wide mouth plastic container 1 is shown having a longitudinal central axis 1 a and comprising a hollow body 11 (shown in dashed lines) terminating in a reinforced short neck 10 .

[0032] The hollow body 11 may have any shape and size within the scope of the invention.

[0033] Within the scope of the invention, the wide-mouth plastic container 1 can be manufactured from any thermoplastic material. Among these thermoplastics, however, polyester resins are the best candidates.

[0034] More specifically, polyester resins suitable for carrying out the ...

Abstract

A container (1) and a screwable closure (2) comprising a hollow body (11) and a neck finish (10) terminated by a wide-mouth opening (100). Said neck finish comprises a neck support ring (102) and a neck portion (101) extending between the wide-mouth opening (100) and the neck support ring (102). The neck portion (101) comprises an upper portion (1010) and a reinforced lower portion (1011). The inner face (1011 b) of the reinforced lower portion (1011) is transitioning to the inner face (1010b) of the upper portion (1010) along a transition step (1011c) in such a way that said reinforced lower portion (1011) is thicker than the upper portion (1010) at least in a top part of the reinforced lower portion (1011). The neck support ring (102) is below the removable closure (2).

Description

technical field [0001] The present invention relates to an assembly comprising a wide mouth plastic preform or container with a reinforced neck and a removable closure screwable to said wide mouth plastic preform or container. Background technique [0002] Plastic containers, more specifically polyester containers, and more specifically polyethylene terephthalate (PET) containers, are now used more than in the past to package a variety of commodities that were previously served in glass containers. Manufacturers and bottlers, as well as consumers, have recognized that PET containers are lightweight, recyclable and can be easily mass-produced. [0003] PET is a crystallizable polymer, meaning it can be obtained in amorphous or semi-crystalline form. The ability of a PET container to maintain its material integrity is related to the percentage of the PET container that is in crystalline form (also referred to as the "crystallinity" of the PET container). [0004] Container m...
