Abstract
A packaging device, particularly for packaging trays containing food products or technical materials in a controlled atmosphere and by means of a film of plastic material, comprising an upper chamber and a lower chamber, which can be fastened by mutually superimposing them and are each provided internally with a plurality of heat-sealing and/or cutting and/or die-cutting elements arranged concentrically, the lower chamber being provided centrally with a plurality of supporting elements for a tray.
Claims25
A packaging device, for packaging trays containing food products or technical materials in a controlled atmosphere and by means of an unwound film of plastic material, the device comprising:
- a roll adapted to unwind said film;
- a winder to rewind said film;
- an upper chamber and a lower chamber, adapted to define a chamber for accommodating a tray;
- said upper chamber and said lower chamber being arranged to be fastened by mutual and vertical superimposition and being each provided internally with a plurality of heat-sealing and/or cutting and/or die-cutting means arranged concentrically, said lower chamber being provided centrally with supporting means for said tray;
- said supporting means being vertically movable;
- said plurality of heat-sealing and/or cutting and/or die-cutting means of said upper chamber comprising a series of upper pressers arranged concentrically, said series of upper pressers being movable in respect to the upper chamber;
- said plurality of heat-sealing and/or cutting and/or die-cutting means of said lower chamber comprising a series of lower pressers corresponding to said upper pressers;
- said lower pressers comprising blades adapted to cut said film during a work cycle of the device.
A packaging device, for packaging trays containing food products or technical materials in a controlled atmosphere and by means of an unwound film of plastic material, the device comprising:
- a roll adapted to unwind said film;
- a winder to rewind said film;
- an upper chamber and a lower chamber, adapted to define a chamber for accommodating a tray;
- said upper chamber and said lower chamber being arranged to be fastened by mutual and vertical superimposition and being each provided internally with a plurality of heat-sealing and/or cutting and/or die-cutting means arranged concentrically, said lower chamber being provided centrally with supporting means for said tray;
- said supporting means being vertically movable;
- said plurality of heat-sealing and/or cutting and/or die-cutting means of said upper chamber comprising a series of upper pressers arranged concentrically, said series of upper pressers being movable in respect to the upper chamber;
- said plurality of heat-sealing and/or cutting and/or die-cutting means of said lower chamber comprising a series of lower pressers corresponding to said upper pressers;
- wherein said plurality of heat-sealing and/or cutting and/or die-cutting means of said lower chamber is a plurality of cutting and/or die-cutting means.
A packaging device, for packaging trays containing food products or technical materials in a controlled atmosphere and by means of an unwound film of plastic material, the device comprising:
- a roll adapted to unwind said film;
- a winder to rewind said film;
- an upper chamber and a lower chamber, adapted to define a chamber for accommodating a tray;
- said upper chamber and said lower chamber being arranged to be fastened by mutual and vertical superimposition and being each provided internally with a plurality of heat-sealing and/or cutting and/or die-cutting means arranged concentrically, said lower chamber being provided centrally with supporting means for said tray;
- said supporting means being vertically movable;
- said plurality of heat-sealing and/or cutting and/or die-cutting means of said upper chamber comprising a series of upper pressers arranged concentrically, said series of upper pressers being movable in respect to the upper chamber;
- said plurality of heat-sealing and/or cutting and/or die-cutting means of said lower chamber comprising a series of lower pressers corresponding to said upper pressers;
- said lower pressers being constituted by concentric rings of equal height, whose function is to abut against perimetric edges of the corresponding and overlying upper pressers, said lower pressers being provided, at the lateral edges that are adjacent to the end that faces said upper pressers, with blades which are adapted to allow the cutting of said film during a work cycle.
