Abstract

A machine for making packages containing liquid or creamy products includes stations for punching/forming a first blank defining upper, lower and rear faces of the open package. A punching and creasing station forms a second blank defining first and second lateral faces of the package. The second blank has a notch for partial transversal separation between the first and second lateral faces. A station for assembling the first blank with the second blank for opening/closing the package with the notch of the two lateral faces, arranged in a “V”, to form an edge of the package. A transport unit is movable along a feed direction and configured to receive the package from the assembly station. A station opens the edge and fills the package with a dose of the product fed through the open notch. A station seals the notch.

Claims16

Dependent claims

A machine for making packages containing liquid or creamy products, the package being prismatic triangular in shape, when formed, and having an upper face and a lower face opposite to the upper face which are triangular in shape, a rear face and a first and second lateral face for joining and connecting the upper and lower faces;

the machine comprising:
a station for punching and forming a first flat blank in a single sheet defining the upper face, the lower face and the rear face of the package when the package is formed;
a station for punching and creasing for formation of a second flat blank in a single sheet defining the first and the second lateral face of the package, when the package is formed;
the second blank having at least one cut of partial transversal separation between the first and the second lateral face;
an assembly station for assembling the first blank with the second blank to form the package in a closed condition with the at least one cut between the first and the second lateral face, positioned along an edge of the package when formed;
a transport unit, movable along a feed direction, and configured to move the package from the assembly station along an operating section;
an opening and filling station forming along the edge an edge opening of the package by distancing the first and the second lateral faces at the cut along the edge and filling the package a dose of a product through the edge opening of the package;
the opening and filling station being positioned along the operating section of the transport unit;
a sealing station for sealing the edge opening of the package;
the sealing station being positioned downstream of the opening and filling station with respect to the feed direction.

A process for making packages containing liquid or creamy products, the package being prismatic triangular in shape, when formed, and having an upper face and a lower face opposite to the upper face which are triangular in shape, a rear face and a first and second lateral face for joining and connecting the upper and lower faces, wherein the process comprises the following steps:

forming, by punching, a first flat blank in a single sheet defining the upper face, the lower face and the rear face when the package is formed;
forming, by punching and creasing, a second flat blank in a single sheet defining the first and the second lateral face of the package, when the package is formed;
the second blank having at least one cut of partial transversal separation between the first and the second lateral face;
assembling the first blank with the second blank to form the package, with the at least one cut between the first and the second lateral face, positioned along an edge of the package when formed;
after assembling, using a transport unit movable along a feed direction and configured to receive the package to move the package along the feed direction along an operating section;
opening the package by distancing the first and the second lateral face at the cut along the edge so as to form an edge opening of the package;
filling the package with a dose of product through the edge opening of the package, both the opening and the filling occurring along the operating section;
and
sealing the edge opening for fully closing the package.
