Definitions
- the invention relates to a method for packaging food under protective gas in a plastic cup with a flexible lid.
- Such methods are carried out in cycles and include the steps of product filling, protective gas purging, lid placement and lid welding.
- the inert gas purging is carried out in such a way that the inert gas, for example nitrogen, carbon dioxide or argon, is blown into the cup filled with product from above via one or more gas nozzles. It can be seen immediately that with this procedure large specific amounts of protective gas are required to fill the head space of the cup with protective gas.
- the cup filled with product usually has a head space of 50 to 100 ml, which is designed as a flat disc with a maximum height of 10 mm. Adequate gas exchange in this open headspace is only possible when flushing with shielding gas quantities that are a multiple of the headspace volume.
- a reduction in the shielding gas requirement can be achieved if the shielding gas is only flushed when the cover is already in place but not yet welded.
- Such a method is shown in DE-A-2 419 682.
- the lid is glued as a film onto a large number of flat rectangular containers by closing three sides of the respective container opening in a first step, while by means of a flat nozzle through the free side Inert gas is flushed into the container. In the next step, the empty container side is also closed. This method is limited to the use of foils for the production of the lids in the packaging process.
- US-A-3 360 382 shows a method for closing flat containers, in which prefabricated lids with a certain curvature are used.
- the invention is therefore based on the object of providing a method for packaging food under protective gas in a plastic cup, which is distinguished by a low specific protective gas consumption, prevents the penetration of atmospheric oxygen into the head space of the cup flushed with protective gas, and the use of non-pretreated Individual lids made of any material are permitted.
- the lid can be raised in a variety of ways.
- a procedure in which the lid tear-off tab slides over a wedge has proven itself well.
- the protective gas is preferably supplied through a hole in the thick wedge end.
- Another procedure for lifting the lid, which has proven itself in practice, is that the lid on the lid pull tab is raised by means of the gas nozzle for blowing in the protective gas.
- the gas nozzle is raised in the vertical direction and lowered again.
- Fig. 1 shows the links 1-7 of a conveyor belt with which the plastic cups 9-13 are cyclically transported to the individual work stations.
- the direction of conveyance is indicated by arrows 8.
- the metering device 14 for the product 15 to be filled is located above the plastic cup 12.
- a work station further away is the lid storage container 16 above the plastic cup 11.
- a cover 17 already lies on the plastic cup 11 here.
- purging takes place with protective gas, which is supplied through the gas nozzle 18.
- the lid 19 located on the plastic cup 10 is shown by a dashed line Line shown.
- the lid 19 is slightly raised from the edge of the plastic cup 10, on one side by the gas nozzle 18, on the other side by the escaping gas 20.
- the lid 19 is held by two hold-down devices, not shown in FIG Plastic cup 10 fixed.
- the last work station finally shows the plastic cup 9 with the lid 22, which is welded onto the edge of the plastic cup 9 with the aid of the welding head 21.
- the covers 17, 19 and 22 are preferably made of aluminum. Plastic lids can also be used.
- the rinsing of the head space of the cup 10 of FIG. 1 is shown enlarged according to the invention.
- the lid 19 is slightly raised on the lid pull tab 23 by an upward movement of the gas nozzle 18.
- the protective gas is then blown in, which is indicated by the arrows 24.
- the gas 20 escaping from the head space of the cup 10, ie air, mixed with protective gas, also lifts the lid 19 on the opposite side.
- the gas nozzle 18 is lowered and moved to the side so that the plastic cup 10 can be conveyed to the next work station in the next work cycle.
- the movement of the gas nozzle 18 in the vertical direction is represented by arrows 25, the lateral movement of the gas nozzle 18 by an arrow 26.
- the lateral movement of the gas nozzle 18 is superfluous when the protective gas is blown in from the side of the conveyor belt, ie 90 ° offset from the arrangement shown.
- two hold-downs 27 are used, the movement of which is indicated in the vertical direction by the arrows 28.
- the Fig.4 u. 5 show another embodiment of the invention: on the links 29, 30 u. 31 of a conveyor belt are the plastic cups 33, 34 u. 35.
- the direction of conveyance of the conveyor belt is indicated by arrows 32.
- On the plastic cups 33-35 are the aluminum covers 36, 37 u. 38.
- a fixed wedge 39 is used to lift the lid 37, which when the plastic cup 34 moves forward in the conveying direction is pushed under the lid pull tab 40 of the lid 37 and raises it slightly according to its thickness.
- the shielding gas 42 is blown in through a bore with feed pipe 41 in the thick end of the wedge 39.
- the escaping gas is represented by arrows 43. Fixing the lid 36, 37 u. 38 occurs in this process variant by spot welding 44, 45 and 46.
- the method according to the invention practically excludes that after purging with protective gas, oxygen from the environment again reaches the headspace of the plastic cup. This is also achieved with a small amount of protective gas that was previously not considered possible. In practical operation it has been shown that the protective gas consumption per cup is less than three times the headspace volume.
