Abstract
The method relates to a method for packing articles and/or objects. Articles are packed in an elastic packing material (2) and the elastic packing material is stretched during the packing process. To achieve this, the packing material is arranged in a receptacle (1) in which a partial vacuum is produced. The packing material is stretched due to the pressure that the outside air exerts upon it. The item that is to be packed is then placed in or on the packing material. Once the vacuum has been removed, the packing material automatically reverts back to its original position by virtue of its own elasticity and is applied to the packing items. The invention also relates to a device to carry out such a method.
Claims30
A device to package at least one article with an elastic packaging material, comprising:
- a receptacle (1, 23, 52, 71, 72) in which a partial vacuum is generated, at least two openings disposed in the receptacle, wherein one opening is for inserting the at least one article and a second opening for the infeed of a sleeve (26);
- said second opening is closed airtight for feeding the sleeve (26);
- and a piston (24) in which the infeed opening (25) for the sleeve (26) is located.
A device to package at least one article with an elastic packaging material, comprising:
- a receptacle (1, 23, 52, 71, 72) in which a partial vacuum is generated, at least two openings disposed in the receptacle, wherein one opening is for inserting the at least one article and a second opening is disposed in the receptacle, said second opening for a sleeve (26);
- said second opening is closed airtight for feeding the sleeve (26);
- wherein the feed opening for the sleeve (26) is configured areally enlarging in the direction of the space (36) in such a way that the feed opening has a widened configuration.
A method for packaging articles in a packaging device, comprising the steps of:
- feeding an elastic packaging material into a receptacle as a foil sleeve (26) through an airtight initial opening in the receptacle;
- feeding a sleeve portion (26a) having an open end through the receptacle;
- placing at least one displaceable mechanical means on the open end of the sleeve portion in the receptacle such that all edges of the receptacle are contacted and overlapped forming a space (36), said space being airtight from an external atmosphere;
- generating an atmospheric partial vacuum in said space (36) for expanding the sleeve portion (26a);
- inserting at least one article into the sleeve portion (26a);
- restoring the shape of the sleeve portion such that it clings to the article;
- and
- separating the sleeve portion from the fold sleeve (26).
A method for packaging meat products in a packaging device, comprising the steps of:
- feeding an elastic packaging material into a receptacle as a foil sleeve (26) through an airtight initial opening in the receptacle;
- feeding a sleeve portion (26a) having an open end through the receptacle;
- placing at least one displaceable mechanical means on the open end of the sleeve portion in the receptacle such that all edges of the receptacle are contacted and overlapped forming a space (36), said space being airtight from an external atmosphere;
- generating an atmospheric partial vacuum in said space (36) for expanding the sleeve portion (26a);
- inserting at least one meat product into the sleeve portion (26a);
- restoring the shape of the sleeve portion such that it clings to the meat product;
- and
- separating the sleeve portion from the fold sleeve (26).
