"Dishware and method for sealing partially prepared food"

The present invention relates to a tableware, and more particularly to a plate for the packaging, transportation and / or eating of food, the dish having a body covered with a film, and adhesive (adhesive glue) for sealing between the film and the body the Geschirreinheit is present.

The prior art discloses dishwashing units and methods of sealing

Crockery with dishes arranged thereon has become known.

It is the object of the present invention to provide a dishwashing unit and a method for sealing, with which high-quality and also top-quality foods and at least partially at least partially prepared foods can be taken, preserved and transported and / or consumed. For example, food arranged on the tableware may be part of a menu.

This object is achieved by a Geschirreinheit with the features of claim 1 and by a method having the features of claim 19. Preferred developments of the invention are subject of the dependent claims. Further advantages and features of the invention will become apparent from the general description and from the description of the

Embodiments.

A dish according to the invention is designed in particular as a plate and serves for the packaging, the transport and / or the consumption of food. Furthermore, the

Tableware also for the preparation and / or preparation of food or

Components are used, for example, a menu. The Geschirreinheit includes a particular temperature-resistant body. The body is covered with a foil.

An adhesive is present in an adhesive area between the film and the body to seal the tableware. In this case, the film and the Geschirreinheit (in particular the plate) on such a surface tension that the adhesive when removing the film at least predominantly adheres to the film. For this purpose, the adhesive used should have a specific adhesion.

With the formulation that the adhesive at least predominantly adheres to the film when the film is removed from the tableware, in the context of the present invention, it is to be understood that at least 90% or at least 95% of the mass of the adhesive is removed on removal of the film Slide adheres. In particular, at least 99% of the mass of the adhesive remains on the film when the film is removed. These figures apply to

BESTATIGUNGSKOPIE the regular case. It is not excluded that, for example, in one of 20, 50 or 100 cases, a greater percentage of the adhesive will remain on the dish unit.

However, when removing the film, the adhesive usually dissolves as far as possible or practically completely from the dish unit, so that no further cleaning of the gluing area of the dish unit is required before the ready-made meals are consumed.

The Geschirreinheit invention has many advantages. A significant advantage is that after the removal of the film from the Geschirreinheit the food can be prepared directly to the end or are available directly for consumption, if a further preparation is not necessary. As a result, without special precautions or without any special effort the sealing film can be removed from the Geschirreinheit without unsightly residues of the adhesive remain on the Geschirreinheit. As a result, a visually pleasing overall impression is achieved.

In a preferred development, the body has at least one mirror section and at least one edge section. Particularly preferred is the adhesive area on the

Edge section formed. In particular, the mirror section serves to receive at least one feed. It is also possible that not only a mirror section is formed, but that a plurality of mirror sections are provided or formed on the body.

For example, a second or separate mirror section can be provided, which serves to accommodate a separate container or a separate shell, such as a pot for sauce or for other foods or ingredients. It is preferred that at least one edge portion extends around the body, thus completely surrounding a central portion of the body. It is further particularly preferred that the adhesive region or at least one adhesive region extends completely and around the body. It is preferred that at least one mirror section is surrounded by a continuous adhesive area as a whole, so that a complete and secure

Seal the food on the Geschirreinheit can be guaranteed. The adhesive should form a closed ring after application on the body, otherwise

For example, a protective gas mixture introduced under the film could escape.

Preferably, the edge portion is at least in the gluing area opposite to

Mirror section increased. Such an edge portion facilitates gripping the

Tableware or the plate and also the settling on a table or in a

Cooking appliance. An edge portion raised in the adhesive area can also facilitate the application of the adhesive in the adhesive area, for example when the adhesive is applied over rollers or the like.

It is possible and preferred that an application surface for the adhesive is formed on the body, which provides the adhesive area. Such a job surface can For example, be formed on an extending along the adhesive region increase. The application surface preferably has defined dimensions and can

in particular have a width between 1, 5 mm and 10 mm and in particular between about 2 and 6 mm. For example, a width of about 3 or 4 mm (+ 1-2 mm) is possible.

Overall, the body preferably has a width between 10 cm and 25 cm and a length between 20 cm and 38 cm. In preferred embodiments, a width between 15 cm and 20 cm and a length between 25 cm and 35 cm may be present.

In particular, the dimensions of the body are adapted to the dimensions of the cooking appliance and in particular to the cooking chamber of the cooking appliance, so that the cooking chamber can accommodate a predetermined number of Geschirreinheiten without large gaps (greater than 2 cm or 3 cm) arise and thereby receiving space for the dishes are given away. With dimensions of a Gargutaufnahme a cooking appliance of 42.5 cm wide and 35.5 cm in length can be placed next to each other preferably two dishes on the food support, on the one hand still enough space to maneuver the

On the other hand, not too much space is given away.

Overall, the dimensions of the Geschirreinheit should be chosen so that when placing the maximum possible number of dishes on a Gargutträger at least 10% or 20% and a maximum of 30% or 40% of the food support remains free.

Particularly preferably, the body consists at least partially and in particular at least substantially or completely of a ceramic-like material. In particularly preferred developments, the body consists at least partially or essentially or completely of magnesium oxide. Crockery units made of a ceramic-like and / or magnesium oxide material can be produced in various forms and are suitable because of their nature for the preparation and consumption of food. Magnesia based on magnesium oxide are lighter than conventional porcelain and yet just as impact resistant. As a result, such Geschirreinheiten are particularly suitable for regular and professional use, for transport and for multiple use.

Particularly preferably, the body is designed substantially rectangular or polygonal.

It is possible and preferred that at least one corner is designed rounded.

Rectangular or substantially rectangular configurations allow a high

Packing density.

The film for covering (and sealing) the food on the tableware is preferably made of a plastic material and has a thickness between 50 pm and 150 pm. Particularly preferably, the film consists at least partially or in particular completely of a material such as polyethylene terephthalate (PET). Preferably, the bottom of the film is connected to the body of the Geschirreinheit.

Particularly preferred is at least one surface treatment the

Surface tension changed at the bottom of the film. It is possible that also the top of the film is subjected to a surface treatment or the like.

Preferably, at least a portion of the underside of the film is surface treated by a corona treatment. In a corona treatment, the film is usually exposed to an electrical Flochspannungsentladung. If only one side of the film is treated, the film can rest on a polished roller, for example, while an electrode is arranged on the other side of the film. For surface treatment is usually a

Floating frequency generator used with an AC voltage between about 10 and 20 kV and a frequency between 10 and 60 kHz. Also other voltage ranges and

Frequency ranges are possible for treatment. By a specific adjustment of the kind, intensity and length of the surface treatment (adjusted for example by the

Propulsion speed of the film), the desired surface tension of the film is set.

Preferably, the surface tension of the lower surface of the film is adjusted at least in the adhesion region on the film such that the surface tension on the film is greater than the surface tension in the adhesion region on the body. In concrete

Embodiments, it is preferable that the surface tension at the lower surface of the film is larger than 42 mN / m (also dyn / cm), and that the surface tension in the adhering area of the sheet is, for example, 41 mN / m or less.

In preferred embodiments, at least one food is arranged on the body and covered by the film. The space between the body and the food is preferably partially vacuumed. In particular, a vacuum is generated in the height between about 100 mbar and 400 mbar. Even more advantageous is a partial vacuum between about 200 mbar and 300 mbar.

In advantageous embodiments, a gas mixture is present in the intermediate space. The composition of the gas mixture depends on the sealed food, e.g.

Meat components require a different oxygen content (preservation of the typical red color of meat), which is not necessary for food without meat (eg vegetarian dishes or desserts). Particularly in the case of meat dishes, the gas mixture consists of more than 50% CO 2 and preferably more than 10% N 2 and in particular less than 20% and preferably less than 10% 02. Preferably, the proportion of oxygen is further reduced to 7%, 6% or 5%. The number of nitrogen is preferably between 15% and 25% and the proportion of carbon dioxide is preferably more than 60 or even 70%. In a specific embodiment, a gas mixture of about 75% carbon dioxide and 20% nitrogen and 5% oxygen is used. Such embodiments are very advantageous because the reaction and aging of the food is avoided or delayed to a considerable extent by the high proportion of inert gases. Another advantage is that the oxygen content avoids visible discoloration of, for example, beef, which tends to assume a greyish surface when there is no longer any ambient oxygen. By the

Replacement of the natural air by the gas mixture just described or one of the gas mixtures just described, the shelf life of the food is significantly increased and can be doubled, for example. This improves the shelf life. In preferred embodiments, the proportion of oxygen in the gas mixture is greater than 2% and in particular between 3% and 10%.

In advantageous embodiments, the supernatant film is cut without contact outside the body. As a result, for example, a so-called "Out-CUT method" can be used, in which the film is cut off with a knife close to the body. As a result, a visually appealing impression of the sealed Geschirreinheit is achieved.

Preferably, the adhesive is applied with an adhesive applicator machine comprising nozzles and / or fixed elements such as scrapers and / or orbiting elements such as rollers. Preferably, the tableware is guided over, for example, transport rollers with, in particular, a silicone coating through the adhesive application machine, while the adhesive is applied during the continuous transport of the dishwashing unit.

In preferred embodiments, the adhesive is a hot melt adhesive. More preferably, the adhesive is a sticky-melt adhesive based on polyolefin. Particularly preferably, the adhesive at 160 ° C has a viscosity greater than 1500 millipascal seconds. For example, the viscosity may reach or exceed about 2200 millipascal seconds at 160 ° C.

The inventive method is used for sealing at least partially prepared food, wherein the food is positioned on a Geschirreinheit and covered with a film. It is applied to an adhesive area of the Geschirreinheit adhesive and a film glued to it. A surface tension of the film and / or the dishwashing unit is influenced in such a way that when the film is torn off, the adhesive at least predominantly adheres to the film. In particular, the adhesive adheres largely and in particular

as far as possible and particularly preferably almost completely or completely on the film.

With the method according to the invention can be advantageously sealed at least partially prepared food on a Geschirreinheit. Advantageously, the underside of the film to be glued to the dish unit is at least partially surface-treated in order to increase the surface tension of the underside of the film. Preferably, at least one adhesive is applied to the adhesive area of the dishwashing unit (or the film) via rolling, stripping, knife-coating and / or spraying.

It is preferred that a space between the tableware and the film is partially vacuumed and / or at least partial gas exchange is carried out in the space between the tableware. Such a gas exchange should take place before the film is glued. Preferably, the gas exchange is carried out before the

Space between the Geschirreinheit and the film is partially vacuumed. Also conceivable are other designs.

In particular, it is preferred that at least one inert gas is supplied to the space between the dishwashing unit and the film. Such an inert gas can in particular

Contain carbon dioxide or be carbon dioxide. It is also possible that to a small or larger extent noble gases are fed as inert gas.

Further advantages and features of the present invention will become apparent from the

Figure 1 shows a highly schematic plan view of a Geschirreinheit 1, which is formed as a rectangular plate and a body 2 comprises. The body has a mirror portion 3 and a rim portion 4, here at the longitudinal and transverse edges a total of 4

Includes edge segments. The edge portion 4 limits the mirror portion 3 laterally. The mirror section provides enough space for a plurality of meals 30, the

may be part of a menu, for example. It is possible for a full menu to be placed on the Dish Unit 1. Of these foods, at least some may be partially prepared, i. H. be at least partially pre-cooked. All components of a plate can have the same state of matter, but the constituents on different plates can also have different states of aggregation. For example, a first dish may contain frozen food and another

Dish only food with refrigerated ingredients.

In the concrete embodiment, the dish unit 1 has a dish width 5 of about 17 cm and a dish length 6 of about 33 cm. But others are possible

Dimensions. In particular, the outer dimensions of the dishwasher unit 1 are adapted to the inner dimensions of a cooking plane 102 of a cooking chamber 101 of a cooking appliance 100. Particularly preferably, two dishwasher units 1 can be placed simultaneously on the cooking level 102 of the cooking appliance 100. This allows two or preferably four

Dishwashers 1 (on two garden levels) can be recorded simultaneously. Preferably, the cooking chamber width 105 is slightly more than twice as large as a width 5 of the Geschirreinheit and / or a cooking chamber length 106 is slightly more than twice as large as a length 6 a Geschirreinheit. The dishwasher units should fill a cooking level 102 of the cooking chamber 101 as completely as possible, but also leave a small space between them and to the cooking space walls. This allows the operator to easily remove the individual dishes. It is particularly advantageous if the gap between the dish units and around them amounts to 10% to 40% and in particular 20% to 40% of the surface of the cooking plane.

The cooking appliance 100 has at least one high frequency heating source 103, whose

radiated frequency can be changed controlled in operation. Preferably, the radio frequency energy is radiated from at least two antennas (not shown) and the radiated frequencies of the radio frequency heating sources 103 and their phases can be varied depending on measured scattering parameters. As a result, specific areas and / or specific constituents or foods 30 can be cooked or regenerated on the dish units 1, while other foods 30 remain virtually or completely unaffected by the high frequency heating source 103 due to their composition and / or consistency. By the simultaneous admission of two or more Geschirreinheiten can according to two or more dishes served on the dishes purified and / or cooked to the end at the same time. As a result, the number of cooking devices required at the same time decreases accordingly if the final preparation of a meal is to be carried out simultaneously for a group of persons.

It is possible that the cooking appliance 100 in addition to the high-frequency heating source 103 still has other heating sources, as used in conventional cooking appliances.

Figure 2 shows a Geschirreinheit 1 in a highly schematic cross-section. The body 2 of the dishwasher unit 1 has a mirror section 3 and an edge section 4, the edge section 4 here comprising an oblique section and an adjoining horizontal section, which is aligned essentially parallel to the mirror section 3. The oblique region has an angle 7, which is for example between 10 and 45 °. Alternatively, the edge portion may also be rounded or angled. It is possible that on the edge portion 4, a decorative edge is formed, for example, has a circumferential pattern.

Figures 3 and 4 show a concrete embodiment of a Geschirreinheit 1 in a plan view and in a cross section. The Geschirreinheit 1 is substantially rectangular in shape and has rounded corners. The body 2 of the dishwasher unit 1 here comprises a large mirror section 3, which fills the essential part (> 50% or> 75%) of the surface of the body 2. The mirror portion 3 surrounds an edge portion 4, which serves to grasp the Geschirreinheit 1 and also for fixing the film 15. Here in the embodiment, a second mirror portion 23 is formed separately on the body 2, which serves for receiving a separate container 24, for example. In the container 24, for example, sauce can be accommodated or other components can be positioned there.

The outer edge 9 here forms the handle edge for gripping the Geschirreinheit.

The adhesive area 8 is provided on an application surface 18, which is formed here by an elevation 19 in the edge portion 4. The elevation 19 with the adhesive area 8 is completely circumferential and surrounds the mirror portion 3 completely. As a result, a reliable sealing of food 30 can be ensured on the Geschirreinheit 1.

FIG. 5 shows a highly schematic representation of an adhesive application machine 20 through which dishwashing units 1 pass through in a continuous process and are provided with a coating of the adhesive. For application of the adhesive nozzles 26 and / or scrapers 27, but preferably a rotatable roller 28 are used, which by a

Reservoir 31 with an adhesive reservoir 33 adhesive or sealing material 21 is supplied. The roller has a relief structure to take the adhesive better. Transport rollers 32 that convey the tableware relative to the roller 28 may include a silicone coating or the like from which any adhesive thereon may be easily released.

Figures 6 and 7 show different Geschirreinheiten 1 when gluing the film 15 on the adhesive portion 8 of the Geschirreinheiten 1, wherein in Figure 6, the state prior to sealing the film 15 and in Figure 7, the state after the partial vacuuming and sealing of the film 15 is shown ,

The dishwasher unit 1 shown in FIG. 6, on which a plurality of dishes 30 are arranged, is in principle already covered with a foil 15. Here, the film 15 is shown before the partial vacuum. The size of the film is adapted to the dimensions of the Geschirreinheit 1. The film is made of PET and may in particular have a thickness of 75, 85 or 100 pm.

The space 16 between the film and the body 2 is partially vacuumed to achieve higher durability through less oxygen in the sealed interior.

In addition, protection against slippage of the individual food 30 is achieved on the plate 1. Preferably, at least 20% of the air volume is removed from the gap 16, which would result from directly covering the food 30 with the film 15. Preferably, at least 5% or at least 10% of the volume of the gap is not vacuumed, so that a residual amount of air or, in particular, gas mixture in the

Interspace 16 remains. By partially vacuuming the pressure acting on the food 30 pressure is reduced by the film. With too much vacuuming, the pressure exerted by the film could lead to excessive deformation of the individual food 30, which could cause the food and / or the menu to be degraded in terms of quality and / or taste. By sealing (gluing) are the

Ingredients or food 30 taken protected as without the use of a film 15, since the volume of oxygen in the space 16 is limited. In addition, the food 30 are supported. As a result, a falling over and slipping during transport or when inserting into the cooking appliance 100 is avoided. In addition, a further protection is achieved in that before or after the partial vacuuming the air through a special

Gas mixture replaced, which contains oxygen to a much lesser extent. It is also important here that the packaging machine itself must contain a purified atmosphere before sealing and supplying the protective gas, since the previously in the

Packaging machine prevailing atmosphere must be replaced

Figure 7 shows a Geschirreinheit 1 with a film 15, in which the intermediate space 16 has been partially vacuumed and thus air or gas was removed from the intermediate space 16 in part. Here is also the sealing material or the adhesive 21 on the surface of the

Randabschhitts 4 shown in the gluing area 8. Preferably, the gas mixture is modified at least in the intermediate space 16. This can be done for example by the supply of Inertgasbestandteilen. The replacement of the gas or gas mixture present in the region of the food is preferably carried out before the partial vacuum. For this purpose, a significant component of carbon dioxide is preferably supplied. Preferably, such a gas mixture is supplied that finally in the partially vacuumed gap 16 between about 60% and 85%

Carbon dioxide and between 10% and 30% nitrogen and between 3% and about 10% oxygen. In a specific embodiment, a composition of about 75% carbon dioxide and about 20% nitrogen and about 5% oxygen has proven to be advantageous. The proportion of oxygen in all embodiments is preferably at least 2% and in particular between 3% and 8% or 10%. Too low an amount of oxygen can lead to unsightly discoloration of the food (beef), which creates a visually unattractive impression. The quality of the food can be affected.

FIG. 7 also shows a knife 29 with which the foil section projecting outward beyond the edge of the body 2 can be removed without the knife 29 touching the body 2 of the dish unit 1.

In all cases, before the finished cooking or tempering of the (partially prepared) food 30 in the cooking appliance 100, the film 15 is first removed.

FIGS. 8 and 9 show a sealing device 200 for sealing a tableware unit 1 or the food 30 placed thereon. In this case, the tableware unit is appropriately positioned in a receiving space 206 of the sealing machine 200 or automatically moved into the receiving space 206, for example by a feeder. As described above, on the mirror portion 3 of the body 2 are the

Geschirreinheit 1 ingredients or food 30 positioned to be covered by the film 15. The individual meals 30 can form a menu as a whole. Furthermore, the gap 16 between the film 15 and the food 30 or the

Mirror section 3 are partially vacuumed. For this purpose, the suction device 202 is used.

The film 15 is fed through a film feeder 201 and is then dimensioned or previously suitable. By a blowing device, not shown, air or other gas mixture between the Geschirreinheit 1 and the film 15 is blown and then the film 15 is lowered to the Geschirreinheit 1 with the food positioned thereon. Subsequently, the sealing tool 204 moves the sealing machine 200 down and presses the film 15 here in the exemplary embodiment of the adhesive region 8 of the edge portion 4. The pressing of the film to the sealing material or the adhesive in the adhesive region 8 can also by air pressure or gas pressure respectively. Previously, the film 15 was heated by a tempering device not shown separately, so that it can be stretched easier.

FIG. 9 shows the sealing machine 200 in a second position, in which the

Sealing tool 204 has the edge portion 4 and the adhesive portion 8 of the Geschirreinheit 1 almost reached. As a result, the film 15 applies at least in sections to the adhesive area 8 and to the tips of the food 30 and covers it. After the sealing tool 204 has reached the adhesive area 8 and presses the film 15, the gas mixture is sucked out of the receiving space 206 and thus also from the gap 16 between the film 15 and the Geschirreinheit 1 via the suction device 202. In this case, a pressure control via a pressure measuring unit 203, which detects a measure of an interior space in the intermediate space 16 via the supply line of the suction device 202. However, the pressure sensor is not in the gap 16 between the film and the body of the Geschirreinheit 1. There is a partial vacuum, in which the Vakuumiergrad also depends on the food to be packaged or their components. The parameters to be set on the packaging machine (including sealing time, temperature, level of pressure in mbar) are different for each dish. The fragility of the respective food requires, for example, an adapted partial vacuum.

After sealing, the dish units 1 with the constituents thereon are stored, cooled or even deep-frozen as required. It is important that a deep rusting takes place only after sealing in order to prevent condensation of the film 15 by condensation. Subsequently, the Geschirreinheit 1 can be given in an outer packaging in which more units can be included.

To replace the gas mixture in the intermediate space 16, for example, the

Sealer 200 first fill their interior with the desired gas mixture, so that the gap 16 is filled with the desired gas mixture.

Subsequently, the partial vacuum can be carried out, so that the volume of the intermediate space 16 is provided with the desired gas mixture.

Overall, a Geschirreinheit 1 is provided, which preferably consists of a magnesium oxide porcelain. The Geschirreinheit is designed in particular as a plate and preferably has a total length of about 330 mm (+/- 15 mm) and a

Total width of 170 mm (+/- 15 mm) on. The Geschirreinheit 1 is in particular for the insertion and transport of the packaged with the foil plate in standardized

Gastronorm container suitable. In preferred embodiments, at least one further container may be positioned on the dish unit. For example, a jug or the like may be provided, which for filling with sauces or small

Supplementary components and the like is suitable. The exact positioning of the container is predetermined by a correspondingly large separate mirror section. Such a Separate mirror portion also ensures a defined distance of such a container to the edge portion 4, which is advantageous for the sealing process.

Preferably, an adhesive bond is used which, in particular, provides an adhesive area 8 on an elevation 19 on or in the edge portion 4. The adhesive area 8 is formed circumferentially and continuously and is in particular rounded at the corners, so that the adhesive can be applied as a sealing material uniformly and sealable.

The adhesive used preferably has a high stability and in particular a viscosity of at least 1500 millipascal seconds at a

Application temperature of about 180 °. Furthermore, the adhesive for the

Food contact suitable.

It is possible that a decorative edge is provided in the edge portion. But it is also possible that the plate is formed without decorative edge.

Preferably, a PET film is provided for sealing the food and / or at least partially prepared menu components, in particular also

is food contact suitable. The subsequent preparation of food in a cooking appliance regularly requires the removal of the film before preparation. For this purpose, it is ensured that with the removal of the film, a far-reaching and, in particular, as far as possible or complete detachment of the adhesive bond is ensured. The remain of, for example, surface residues of the adhesive on the edge of the plate would be disadvantageous and unfavorable in use.

To ensure that the adhesive dissolves as completely as possible with the detachment of the film from the tableware, the film has a correspondingly adapted surface tension of at least 38 mN / m and in particular 42 or 43 or 44 mN / m.

In particular, it is very advantageous if the surface tension of the film used is greater than that of the plate. For these purposes, at least the underside of the PT film used is at least partially treated by a surface treatment. In particular, a corona treatment is performed. In this case, the food-facing side of the surface treatment is subjected. The dose to be introduced in corona treatment is the specific input of electrical energy into the moving foil web. Basically, the adhesive behaves in such a way that it always tends towards the higher surface tension. The sizing of

Corona treatment must always be aligned at the required level to maximize the subsequent adhesion of the food so covered to the underside of the PET film. The application of the adhesive to the Geschirreinheit 1 is carried out with an adhesive application machine, the adhesive application machine can have both fixed elements and orbiting elements and nozzles. In a preferred embodiment, a rotating element is taken into account by shearing a so-called crumb formation

submissions. The adhesive Hafthotmelt adhesive is preferably applied with a clearly specified amount and temperature.

In the sealing process, it is preferred that when the film is pressed, the tool does not touch the tableware unit 1. The pressure can be effected for example by gas pressure, in which a gas mixture is blown onto the film. This prevents the plate from being damaged.

Overall, the invention provides an advantageous tableware with food arranged on the body covered by a foil, and an advantageous method of sealing is provided.
