Definitions
- the invention relates to frozen foods with food from the Group of pies, cakes, fruits and vegetables and one in the manufacturing company closed outer packaging for every frozen food.
- frozen food is the technical term for frozen food that is in the Retail and household in freezers and freezers Temperatures below -18 ° C without significant loss of quality over many Months can be stored (BROCKHAUS, compact edition, 1983, Volume 22, page 49).
- Frozen food is an important cornerstone in the food supply the population. If the cold chain from the manufacturer to the end user not interrupted, the frozen food almost guarantees a temporal unlimited shelf life. The legislator is writing one Temperature of at most -24 ° C before.
- the storage of frozen food provides in catering establishments and Households the ability to quickly supply the unexpected Guests and eliminates the problem of incorrect planning in excursion restaurants, if, for example, the weather suddenly deteriorates.
- a hexagonal folding box is known both as pastry and bottle packaging and as a bottle cooler or waste container provided. is.
- the cooling effect can lamination with an aluminum foil can be improved.
- folding carton has no storage effect and is not for insertion an active, frozen heat sink in the frozen food manufacturing plant intended for accompanying them during transport.
- DE 80 07 232 U1 is a polygonal, for example six or octagonal folding box known also for the shipping of frozen Ice cream cakes to be used. For the partial consumption of Ice cream cake should the individual wall sections independently be hinged. This known folding box also has no storage effect and is not for inserting an active, frozen heat sink provided in addition to the ice cream cake in the manufacturing plant.
- JP 07223677 A is a reusable cool box in the form of a thermoformed plastic container with inner foam walls for the Delivery of numerous beverage bottles known, such as this from camping bags is common.
- the cool box is not an outer packaging in the sense of a Disposable packaging from the manufacturer to the consumer.
- the bottle group that is not frozen food, and not the single bottle, is from one Surrounded so-called cold battery that only made ready for use by the user must become. After absorbing water, allowing it to swell and freezing In a household refrigerator, the cold battery is placed on the bottle group laid on and put around them and forms an active one Cooling medium with storage effect.
- DE 44 15 946 A1 is a flexible cooler pack with a liquid Content known after freezing the content especially for medical Cooling treatment of body parts is provided. Use too such cooling packs for bottle cooling is mentioned.
- the Coolant should be in the solid phase at the initial temperature and a phase change during the cooling treatment while absorbing heat perform in the liquid state.
- the phase transition temperature should be between -25 ° C and 10 ° C.
- the coolant salts or glycols can be added. This well-known cool pack However, it is not part of a prepackage that is on the way from Manufacturer remains unopened until the consumer. Besides, not all are Salts are harmless and glycols are not permitted in the food sector.
- U1 is a reusable alternative to Warming and cooling provided cuff known for replacement the liquid content is reclosed.
- content are hot or cold water, but also cold mixtures in the form of aqueous solutions of calcium ammonium nitrate and urea.
- Tempering is one of the applications of bottles, in particular of beverage bottles, and of cans specified, also the treatment of parts of the body by means of a cooling or warming compress.
- a one-way addition for not hermetically sealed frozen foods from manufacturer to consumer is such a cuff, which is more the function of a hot water bottle and has an ice pack, not.
- the subject of the invention is Frozen food, which is packaged in series production in the manufacturing company and frozen at about -24 ° C and then frozen in the shops brought. It is used, for example, in food departments of Supermarkets in deep freezers for sale to the end consumer through special freezer vehicles from retail chains in large quantities to the end consumer, including households and hospitality companies, delivered. What is not consumed immediately is in freezers or freezers stored further.
- the packaging is designed that an opening is immediately recognizable, so that the goods are not for sale.
- the weak point of such a cold chain is as follows: only a partial one Defrosting the food, which is also the case when the food is opened Packaging can happen is irreparable and leads to the short-term Spoilage of the goods.
- the invention is therefore based on the object of packaged frozen foods specify the genus described at the beginning, which is an effective Protection against premature thawing in the event of a brief interruption of the Owns cold chain
- the solution to the problem is the one specified at the beginning Frozen food according to the invention in that there is between the outer packaging and the frozen food on at least a portion the surface of the food is also a frozen heat sink is made of a closed film envelope with a refrigerant an aqueous solution of at least one substance through which the Freezing temperature of the aqueous solution to values below 0 ° C is lowered.
- sugar and “types of sugar” are defined by law and can be found in "R ⁇ MPP CHEMIE LEXIKON", 9th edition, 1995, pages 5164 to 5165, Georg Thieme Verlag, Stuttgart - New York.
- the film envelope can be made extremely thin-walled, because that Refrigerants no harmful substances such as Glycol and others Contains antifreeze.
- Refrigerants no harmful substances such as Glycol and others Contains antifreeze.
- the concentration of at least one of the substances mentioned is so chosen that the refrigerant, for example, at temperatures down to -12 ° C is liquid, between -12 ° C and -18 ° C it is still plastically deformable and is hard below -18 ° C. It is emphasized that these temperature ranges are only exemplary and allow deviations downwards or upwards.
- the heat sink provides active heat insulation through its heat of fusion, which at least largely maintains its temperature in the melting range.
- the heat sink should be deformable at processing or product temperature be able to cling to the food.
- a refrigerant requires enormous amounts of heat per unit volume for thawing and is therefore a very effective protection against thawing, especially because the heat sink - in contrast to the state of the art - located within the outer packaging and with the Frozen food forms one unit. It also exploits this of empty spaces through conversion into cold rooms.
- the frozen one forms Heatsink also a very effective transport protection against Damage to the content.
- the heat sink can also continue to be used be used to cool drinks etc.
- the Outer packaging is hexagonal and the food is octagonal Outline and if the food is in the area supports its corners in the radial direction on the heat sink. Thereby is a thawing of the thermally particularly vulnerable corners of the Food effectively prevented.
- the refrigerant is at least a flavoring from the group of fruit acids is added, and / or if the refrigerant contains a food-compatible dye is offset.
- the refrigerant is then suitable as after removing the film cover other foods for sucking and / or as a beverage additive fully exploited.
- Figure 1 is a rigid outer packaging 2 in the form of a hexagonal Cartons shown in which the food 1 concentrically in the form an octagonal cake.
- the corners 7 form a division aid for the creation of intersection lines 8, which are only shown in broken lines here.
- a heat sink 3 in the form of a cross section flat, circularly curved tube made of a wafer-thin Foil sleeve 4, in which the refrigerant 5 described above is located.
- the longest axis of the hose cross section is perpendicular to the Drawing level.
- the ends of the film envelope 4 meet at a separation point 9 to each other. The ends can also overlap. It is recognizable, that the food 1 in the region of its corners 7 in the radial direction supported on the heat sink 3, the effective, active heat insulation represents.
- Figure 2 shows that such hexagon packs without gaps fit together and that their contents over the hard frozen heat sink 3 and the box walls on the shortest paths against each other support.
- Figure 3 is a rigid outer packaging 2 in the form of a hexagonal box shown in which the food 1 concentrically in the form an octagonal cake.
- the corners 7 form a division aid for the creation of intersection lines 8, which are only shown in broken lines here.
- a heat sink 3 in the form a cross-sectionally flat, polygonally folded hose from one wafer-thin film sleeve 4a, in which the above described Refrigerant 5 is located.
- the longest axis of the hose cross section runs perpendicular to the plane of the drawing.
- the ends of the film envelope 4a meet one Separation point 9 to each other, but can also overlap and / or with each other be connected.
- the (maximum) edge length of the polygonal Food 1 has the dimension "K".
- the thickness of the heat sink 3 can are between 4 and 10 mm, preferably between 5 and 7 mm, wherein these dimensions are not critical.
- Figure 4 shows a partial side view, i.e. a circumference neckline from a heat sink 3, in which by axially parallel first welding or Sealing seams 11 at a distance "L", which is essentially the dimension "K” in FIG. 3 corresponds, individual chambers and fold lines are formed. At right angles to this run second weld or seal seams 12, through the individual Chambers 13 are formed in which the refrigerant 5 is enclosed on all sides is.
- the welds 11 and 12 can be in relation to the Cross-section are asymmetrical ( Figure 5) or symmetrical ( Figure 6).
- the food according to FIG. 7, an octagonal cake has the shape of a short truncated pyramid, i.e. the surfaces 10 run under one acute angle to an axis, not shown.
- the chambers 13 Figure 4 nestle with the refrigerant 5 when inserting the film cover 4a each of the surfaces 10 as shown in FIG.
