D TA=h8D D$SCRIPTION aF~'~'~ I~ ION
The present~inventfon xelatea to~cheeae and a new packaging system which is useful for packaging cheese. The key advantage of this new packaging System is th~ avoidance of carrying out the entire packaging process under the strict hygiene conditions required to extend shelf-life.
The cheese portions axe simply covered under. those strict hygiene conditions with one preferably uncolored wax layer and all of the remaining packaging steps, i..e. faxing the tear strip onto the first inner wax layer and applying the aacond as. outer wax layer, can than be effected under less strict hygiene conditions, which is moat advantageous.
Preferred embodiments of the invention will now be explained with respect to the drawings.
The cheese may be any known type of cheese, e.g. natural 5 cheese, processed cheese or cream or fresh cheese. Preferably it is procasaed cheese.
As mentioned above, the cheese portion to be packaged can have any desired form but is preferably triangular.
io Fig. la shows in a perspective view a cheese portion 5 which is covered with a first.inner wax layer 1 and which is surrounded on all of its three aide walls w~,th a tear strip 2 which hoe a portion 3 which protrudes from the tip of the is cheese portion 5 and which has as a preferred embodiment a plurality o! holes 6 along its length. The tear atrip~2 has been fixed onto the first~inner wax layer 1 by means of an adhesive.
ao Fig. lb shows the embodiment of Fig. 1a which has been covered with a a~econd outex wax layer 4. The application of the second outer wax layer 4 is carried out under conditions which lead to a melting together of the two wax layers Z, 4 so that they can easily be separated from the cheese portion 5. The Zs two wax layers 1, 4 also melt together through the holes 6 of the tear strip 2 go that it is firmly embedded between the two wax layers 1,4 and allows an acurate opening of the outer wax layer 4 along the lines of the tear strip Z. fhe a~ame applies to the tirst~ inner wax layer 1 which firmly adheres to the 3Q tear strip 2 by means of the adhesive with which it has been fixed onto the first inner wax layer 1 and by means of the holes 6 of the tear Strip 2 through which the two wax layere 1, 4 have been melted~together. As mentioned above, the holes in the tear strip relate to a preferred embodiment of the as invention and are not necessary to carry out the invention.
Normally, the adhesive layer on the tear strip is suEfiaient to form a firm connection to the first firmer way layer i.
x Fig, is shows the same embodiment which has been opened~by tearing away the tear strip 2 from two Bides of the triangular cheeaa portions. It can be seen that the inner side of the tear strip 2 is covered with the first inner wax layer 1 which s has been torn away from the cheese portion 5 and the~tear strip 2 can be easily and completely separated by further tearing the tear strip 2 from the third side wall of the cheese portion 5. Finally, the top and the bottom comprising the second outer wax layer 4 and the attached first inner wax Zo layer ~ can then easily be separated, and the cheese portion 5 is ready for consumption.
If the tear strip 2 has holes, the second outer wax layer ~4 is applied under conditions which lead to a melting together of ~.s the first inner wax layer Z and the second outer wax layer 4 and the melting together also takes place through the holes of the tear strip 2, so that the tear strip ~ ie firmly fixed between the first inner and second outer wax layers 1, 4, so that the tearing away of the tear strip 2 takes with it the 2o corresponding parts o! the first inner wax layer 1 and the second outer way layer 4.
After detaching the top and bottom portions of the second outer wax layer 4 to which the first inner. wax layer 1 firmly 25 adheres, the cheese portion 5 is ready for cor~umption.
A similar embodiment is shown in a perspective view in Fig. 2a to 2c. The tear strip Z is fixed only to the two elongated side walls o~ the cheese portion 5 covered with~the first ao inner wax layer 1 but it has one protruding tear strip portion so that it can bs opened by pulling the tear strip portion 3 towards and around the tip of the .cheese portion 5. Then, the top and bottom portions of the puter wax layer 4 can be opened and the cheese portion 5 is ready for consumption.
3s A further preferred embodiment of the invention is shown in Figs. 3a to 3c. Here, the top and one side wall of the cheese portion 5 are covered with the tear strip 2 which, again, has as a preferred embodiment a plurality of holes 6 throughout and one protruding portion 3.~
The situation after tearing away tear strip 2 is shov~m in Fig.
3c. The top portion of the cheese portion 2 and one of the elongated side walls are separated from the package and the cheese portion 5 can be taken out of the package and consumed.
s.o The process for packaging cheese according to the present invention will now be illustrated~in more detail. The procaes will be described with respect to process cheese. However, as mentioned above, the present invention is usefuli for any typ of cheese.
m Zo As a separate first production step hot and liquid process cheese is filled into casings and cooled down. These casings with proresa cheese can be stored for several days before proceeding with the following production steps.
After removal of the casing the f~.rm process cheese sausage is cut into slices (preferably round) and each slice is cut into portions 5 (preferably 6 portions 5 triangularly shaped). Due to this cutting operation the preferred triangle portion 5 25 consits of 2 straight sides and i rounded side. After the cutting these cheese portions 5 (triangularly shaped) are placed separately on a conveyor belt. Automatically by tranapo~cting on belts and rolls the portions 5 are passing a waxing station. The wax is hot and liquid and will cover the 3o portions 5 completely (preferably the wax is sprayed onto the top and bottom of the portion 5) with a thin fir~at inner wax layer 1 which might be optionally colored. These production stops beginning from the removal of the casing until the first wax layer 1 have to be done under clean room environment.
35 Atter these production steps it is possible to take out the waxed proaese cheese portions and store the portions (prefe-rable under refringeration) for several days.
The. following steps can be done without clean room condition.
1'he pre-waxed process cheeab portions, either from the storage or directly comiag out of the first waxing step, are passing a standard label applicator which adds a.self adhesive label s with or without holes onto the first inner way layer 1.
Here are some options how to apply the label. Further. label shapes and label positioning on the first inner layer wax l are possible.
1. Option: the self adhesive label is a rectangular lengthy io tear strip 2 with ox without holes 6 which is applied onto the two sides of the Brat inner wax layer 1 with a protruding portion 3 (opening handle) on the tip of the triangle (figures i.a-c).
2. Option: the self adhesive label is a rectangular lengthy is tear strip 2 with or without holes 6 which is applied to the two long sides of the first inner wax layer ~. with a protru-ding portion 3 close to the round aide the triangle (tigure~s 2 . a-c) .
3. Options the self adhesive label, nearly triangularly shaped Zo with or without holes 6 ig applied to the top aide and to one of the long aides of the first inner waac layer 1. The protru-diag portion 3 is positioned at a corner of the round side the triangle (figures 3.a-c~.
zs Attar the labal placement onto the process cheese portion the portion is passing again automatically by tran9porting on belts and rolls a~seevnd waxing station. This wax is also hot and liquid and will cover the portions completely (graferable the wax is sprayed unto the top and bottom of the portion) 3o with a thin second outer layer ~ which might be optionally.
colored. the self adheaiva.label is designed such that a part of the label is a protruding portion 3 standing away from the proceos cheese portion and this part is foreseen to be used as the opening handle.
After cooling each waxed process chee9e portion can be further packed. Potential options of packing are wrapping, netting, flow packing or packing into other packaging. The preferred option is wrapping into a thin pre-printed plastic film with an automatic wrapping machine.
s The present invention will now be illustrated by a specific example which, however, ~.s not intended to limit the scope o~
the invertfon.
s.o ~Procesa cheese is filled into sausage casings of approximately 1 meter length and a diameter of 98 mm. After cooling, the sausage casing is removed and cheese slices with a thickness of approximately 14 mm are cut. 6 process cheese portions 5 is are cut out of each round slice with a diameter of 98 mm. The dimension of one triangle cheese portion 5 equals a segment with a 49 mm radius, an angle of 60' and a height of 14 mm.
The weight.per triangle is approx. 20 g, 6 pieces are 120 g.
each triangle is passing a wax bath (white wax, - 85'C) where Zo. the first transparent inner wax layer 1 is added. This wax is a blend o~ hydrocarbon based waxes and plaot:lcs. The triangle portion 5 is moving forward on rolls and the wax is sprayed from the top and from the bottom side to ensure that it ie completely covered by wax. Approximately 1.S g wax (- 0.1 -25 0.~ mm thickness) is added. These operatons are done in a clean room (according to cla$$ 10.000 US Fed. Standard 209 n).
The following next operations are done at "normal environ-mental conditions". After the wax bath the triangle portion 5 is cooling down to temperatures of about 20'C by passing a 30 cOOl,ing call, (cold air circulation). Each portion 5 ie maintained (by belts) in a defined horizontal direction on the conveyor belt. One Bide of, the triangle is in the direction of the tear strip applicator. The tear strip applicator i$tandard equipment, PAGO company is applying a self adhesive tear strip 35 2 which is made of polypropylene and coated with an adhesive layer. Ths rectangular tear strip 2 (preferred embodiment) contains holes 6 (preferably round. but also any other shape l~
is~poesible?. With tha aid of the adhesive one side of the tear strip z is fixed on the inner wax layer 1. By passing a roll the other side o~ the label is pressed onto the inner wax layer i. The tear strip Z is added according figure 2 with one s protruding portion 3 (opening handle). 8ach triangle is passing then a scecond wax bath (blue wax, -. 75'C) where a second outer wax layer 4 is added. This wax is a blend o~
hydrocarbon based waxes, plastics and blue pigments. Ap-proximately 3.0 g blue wax (-. 0.2 - 0.4 cnm thickness) ie xo added. The triangle portion ie moving forward on rolls and the wax iii sprayed from the top and from the bottom side to ensure that it is completely covered by wax. As the tear strip a contains holes the second outer wax layer 4 is partially melting the first ir~ner wax layer 1 in the area of the holes.
zs This results in good rdmaval of the 2 wax layers 1, 4 by pulling off the~tear strip z. otter the wax bath the triangle portions are kept refrigerated (.~ ~t'C) before they will be .
ready for adding a secondary packaging (e. g. cellophane wrapper).

35 Atter these production steps it is possible to take out the waxed proaese cheese portions and store the portions (prefe-rable under refringeration) for several days.
The. following steps can be done without clean room condition.
1'he pre-waxed process cheeab portions, either from the storage or directly comiag out of the first waxing step, are passing a standard label applicator which adds a.self adhesive label s with or without holes onto the first inner way layer 1.
Here are some options how to apply the label. Further. label shapes and label positioning on the first inner layer wax l are possible.
1. Option: the self adhesive label is a rectangular lengthy io tear strip 2 with ox without holes 6 which is applied onto the two sides of the Brat inner wax layer 1 with a protruding portion 3 (opening handle) on the tip of the triangle (figures i.a-c).
2. Option: the self adhesive label is a rectangular lengthy is tear strip 2 with or without holes 6 which is applied to the two long sides of the first inner wax layer ~. with a protru-ding portion 3 close to the round aide the triangle (tigure~s 2 . a-c) .
3. Options the self adhesive label, nearly triangularly shaped Zo with or without holes 6 ig applied to the top aide and to one of the long aides of the first inner waac layer 1. The protru-diag portion 3 is positioned at a corner of the round side the triangle (figures 3.a-c~.
zs Attar the labal placement onto the process cheese portion the portion is passing again automatically by tran9porting on belts and rolls a~seevnd waxing station. This wax is also hot and liquid and will cover the portions completely (graferable the wax is sprayed unto the top and bottom of the portion) 3o with a thin second outer layer ~ which might be optionally.
colored. the self adheaiva.label is designed such that a part of the label is a protruding portion 3 standing away from the proceos cheese portion and this part is foreseen to be used as the opening handle.
After cooling each waxed process chee9e portion can be further packed. Potential options of packing are wrapping, netting, flow packing or packing into other packaging. The preferred option is wrapping into a thin pre-printed plastic film with an automatic wrapping machine.
s The present invention will now be illustrated by a specific example which, however, ~.s not intended to limit the scope o~
the invertfon.
s.o ~Procesa cheese is filled into sausage casings of approximately 1 meter length and a diameter of 98 mm. After cooling, the sausage casing is removed and cheese slices with a thickness of approximately 14 mm are cut. 6 process cheese portions 5 is are cut out of each round slice with a diameter of 98 mm. The dimension of one triangle cheese portion 5 equals a segment with a 49 mm radius, an angle of 60' and a height of 14 mm.
The weight.per triangle is approx. 20 g, 6 pieces are 120 g.
each triangle is passing a wax bath (white wax, - 85'C) where Zo. the first transparent inner wax layer 1 is added. This wax is a blend o~ hydrocarbon based waxes and plaot:lcs. The triangle portion 5 is moving forward on rolls and the wax is sprayed from the top and from the bottom side to ensure that it ie completely covered by wax. Approximately 1.S g wax (- 0.1 -25 0.~ mm thickness) is added. These operatons are done in a clean room (according to cla$$ 10.000 US Fed. Standard 209 n).
The following next operations are done at "normal environ-mental conditions". After the wax bath the triangle portion 5 is cooling down to temperatures of about 20'C by passing a 30 cOOl,ing call, (cold air circulation). Each portion 5 ie maintained (by belts) in a defined horizontal direction on the conveyor belt. One Bide of, the triangle is in the direction of the tear strip applicator. The tear strip applicator i$tandard equipment, PAGO company is applying a self adhesive tear strip 35 2 which is made of polypropylene and coated with an adhesive layer. Ths rectangular tear strip 2 (preferred embodiment) contains holes 6 (preferably round. but also any other shape l~
is~poesible?. With tha aid of the adhesive one side of the tear strip z is fixed on the inner wax layer 1. By passing a roll the other side o~ the label is pressed onto the inner wax layer i. The tear strip Z is added according figure 2 with one s protruding portion 3 (opening handle). 8ach triangle is passing then a scecond wax bath (blue wax, -. 75'C) where a second outer wax layer 4 is added. This wax is a blend o~
hydrocarbon based waxes, plastics and blue pigments. Ap-proximately 3.0 g blue wax (-. 0.2 - 0.4 cnm thickness) ie xo added. The triangle portion ie moving forward on rolls and the wax iii sprayed from the top and from the bottom side to ensure that it is completely covered by wax. As the tear strip a contains holes the second outer wax layer 4 is partially melting the first ir~ner wax layer 1 in the area of the holes.
zs This results in good rdmaval of the 2 wax layers 1, 4 by pulling off the~tear strip z. otter the wax bath the triangle portions are kept refrigerated (.~ ~t'C) before they will be .
ready for adding a secondary packaging (e. g. cellophane wrapper).
