Embodiment Construction

[0022] see first Figure 1-4 , shows a so-called upright, ie self-supporting, package or container 1 having a support base 2 with a peripheral weld 3 extending along the lower edge of the package and along the Two opposing side regions 3' rise.

[0023] The two opposing walls 4, 5 rise from said base 2 and are joined to each other by welds 6 extending along the two opposite side edges of the package and then by the aforementioned side welds. A linear or transverse top weld 7 extending between 6 closes the package above.

[0024] The linear top weld 7 is formed close to the liquid level of the product contained in the package 1 in order to reduce the residual headspace of the package, thereby making the package more rigid and able to support the weight of other packages stacked on top of it .

[0025] The component material of the package 1 is usually a flexible multi-layer sheet with inner layers that can be heat welded.

[0026] According to an important feature of the in...

Abstract

A description is given of a package (1, 1') in flexible material for liquid, pasty products or the like, closed above by a linear head weld (7) which joins two opposed walls (4, 5), at which a pair of opposed welds (10, 11) is provided, in proximity of at least one upper corner (8) of the package, these opposed welds (10, 11) tending to meet at the centre line of the package and determining a flattening of the corresponding upper corner (8).

Description

technical field [0001] The object of the present invention is a flexible package, in particular of liquid, pasty products and the like, in particular food products such as drinks, juices, yoghurts and the like. Background technique [0002] A package according to the invention may for example be a stand-up package, i.e. a self-supporting package when filled with product, having a reinforced support base from which two side walls rise, along the upper edge and side edges, or it may be a parallelepiped container of the "form and fill" type, with gusseted upper and lower closures. [0003] One or other of the above-mentioned types of liquid packages are sold with an upper weld at a distance from the level of the liquid, leaving a headspace which makes the packages soft and prevents them from being stored and / or stacked on top of each other. [0004] These packages are usually opened by cutting the upper corner at the weld or by tearing the package at the pre-formed score. [...
