Problems solved by technology

[0008] Prior art packages certainly offer many advantages, but they are not actually easy to produce
Flexible packaging that will behave as it is intended to be used presents many difficulties in production, mainly related to poor rigidity and inconsistency (large variations in mechanical and geometric properties)

Embodiment Construction

[0029] figure 1 and 2 The package shown in includes a side wall 1 constructed of wrapped laminate, a bottom 2 and a top 3, both of which are secured to the side wall 1 .

[0030] The top 3 is preferably rigid, while the bottom 2 is preferably made of semi-rigid plastic.

[0031] The neck 4 of the package is provided with a rigid flange 7 for handling when moving the tube around before or after assembly of its constituent elements.

[0032] In order to fix the top 3 to the side wall 1 ( figure 1 ), first bringing the mandrel 5 into contact with the two elements 1,3.

[0033] Similarly( figure 2 ), in order to fix the bottom 2 to the side wall 1, the mandrel 6 is first placed in contact with the center of the bottom 2.

[0034] The package is also secured by means of a support cylinder 8 and a support ring 9 .

[0035] It is extremely important to use mandrels 5, 6 inside the package when the top 3 and bottom 2 are welded to the side wall 1, for at least two reasons:

Abstract

The invention relates to a plastic packaging for liquid or viscous products comprising three distinct elements, a flexible cylindrical side wall made from a sheet rolled around a mandrel, an at least partly rigid base and an at least partly rigid upper part comprising a neck, the packaging being able to stand on said base and having a height H and diameter D, the ratio H / D of which is between 1 and 5 and the side wall and the two other elements, on assembly, rest on a mandrel within the packaging. The invention further relates to a method for production of said packaging.

Description

technical field [0001] The field of the invention is that of plastic packaging, which essentially consists of three prefabricated elements, namely the side walls forming a tubular body between a semi-rigid bottom and a rigid neck. These packages have the potential to bring the functionality of bottle-type packaging similar to that of pouch-type packaging. [0002] The invention finds particular but not exclusive use in the following applications: [0003] -Packaging of catering such as fruit juice, vitamin drink, milk, herbal tea, etc. [0004] -Packaging of viscous products such as toothpaste, body lotion, ointment, food (mayonnaise, ketchup, mustard), etc. [0005] -Packaging of technical products such as silicone or mastic. Background technique [0006] A number of different types of packaging correspond to the definitions given above. [0007] An example may be given of the package disclosed in Austrian patent document AT293944, in which a semi-rigid head is welded t...
