Description

[0001] The invention relates to a dish made of expanded polystyrene for containing meat, fish or the like foodstuffs, said dish being provided with a bottom and with side walls joining said bottom and extending upwards from the bottom, whereby openings extending through the bottom are provided in said bottom, which openings are covered at the bottom side of the dish with a foil attached to the dish, which foil is impervious to liquid.

[0002] When using dishes of this type it is a problem to catch the juices released by the products placed on the dish, for example meat juices, in an effective manner, so that such juices on the one hand remain out of sight as much as possible and on the other hand do not flow off upon handling of the dish.

[0003] From European Patent No. 0 046 956 a dish of the above kind is known, whereby a layer of a hydrophilic material is provided at the bottom side of the dish in order to absorb the juices, whilst a foil which is impervious to liquid may furthermore be provided under said hydrophilic layer. In practice it has become apparent that a dish of this type does not under all circumstances fulfil its intended purpose in a satisfactory manner.

[0004] According to the invention at least one recess is provided near at least one opening in the bottom side of the dish, said recess connecting to said opening.

[0005] By providing such a recess an additional capacity for containing liquid moving through the openings is created in a dish of this type, where a comparatively large amount of liquid may collect, so that it is prevented that liquid remains behind on the upper side of the bottom or that said liquid will tend to flow back through the opening upon handling of the dish. Furthermore it will generally be unnecessary to provide a layer of an absorbing material under the dish, because of the comparatively large capacity obtained in this manner. By dispensing with such a layer of an absorbing material and manufacturing the dish and the foil of the same plastic material it is quite possible to recycle the dish and the foil.

[0006] In an advantageous embodiment the opening opens into a first part of the recess, which is in communication with a second part of the recess via a passage, whereby the two parts of the recess are separated from each other by at least one rib, which extends from a boundary edge of said recess into the recess for some distance.

[0007] By using the construction according to the invention any liquid flown from the first part of the recess into the second part of the recess through the passage is prevented from flowing back, as a result of which the flow-back of liquid through the opening to the upper side of the dish is practically excluded when the dish is used in a normal manner.

[0008] The invention will be explained in more detail hereafter with reference to a few embodiments of a dish according to the invention illustrated in the accompanying Figures.

[0022] Figure 14 is a plan view of a further embodiment of a dish according to the invention.

[0023] Figure 15 is a bottom view of the dish according to Figure 14.

[0024] Figure 16 is a sectional view of Figure 15, along the line XVI-XVI in Figure 15.

[0025] As is shown in the Figures the dish comprises a bottom 1 and side walls 2 sloping upwards towards the outside from the circumference of the bottom. A number of ribs 3 slightly projecting from the bottom are provided on the upper side of the bottom.

[0026] Near the centre of the dish a large number of openings 4 extending through the bottom are provided in the bottom of the dish, whereby said openings are configured in such a manner, that the cross-section of an opening gradually increases from the top towards the bottom, as will be apparent in particular from Figure 3. The openings 4 are thereby arranged in rows of aligned openings, said rows extending parallel to the side walls 2.

[0027] As is furthermore apparent from Figures 2 and 3 recesses 5 provided in the bottom side of the bottom connect to the bottom ends of the openings 4 located closest to the side walls 2, said recesses extending from the opening 4 in question in the direction of the nearest side wall 2.

[0028] A further opening 6 corresponding with an opening 4 is provided near each corner point of the bottom. Three corresponding openings 7 are provided near each opening 6. The three openings 7 located near a corner point of the dish thereby lie in a straight line, which extends between the two side walls 2 bounding the corner in question.

[0029] As is furthermore apparent from Figure 2 recesses 8 provided in the bottom side of the dish and extending parallel to the side walls connect on two sides to the lower ends of the openings 7.

[0030] The illustrated embodiment is shown to have rectangular recesses 5 and 8, but it will be apparent that said recesses may also have a different configuration and/or may connect to different and/or further openings.

[0031] The various openings provided in the bottom of the dish are covered at the bottom side of the dish by means of a foil 9 attached to the dish, said foil being impervious to liquid and preferably being made of the same plastic material as the dish.

[0032] In the illustrated embodiment the openings are configured to have a rectangular section, whereby the length of one side of the opening is ± 3 - 4 mm. It stands to reason that also other sectional configurations are conceivable within the spirit and scope of the invention.

[0033] When foodstuffs which exude moisture, such as for example meat, are placed on the dish, any moisture issuing from the foodstuffs can flow into the openings 4, as a result of which said moisture is carried off and disappears from sight. Said moisture will thereby be caught, at least for the greater part, in the large capacity recesses 5 and/or 8, which will prevent the undesirable flow-back of the moisture upon handling of the filled dish.

[0034] In many cases the dishes are placed on a sloping surface, for example in counters or the like, in order to show the food products on the dishes in the best possible manner. The moisture will thereby tend to flow to one side of the dish. By providing in particular the above-described recesses 5 and/or 8 near the sides of the dish, a large capacity for containing moisture has been obtained near the sides of the dish by means of said recesses, so that it can be ensured that moisture is carried off to the bottom side of the dishes in an adequate manner and that there is sufficient capacity for said moisture, also when the dish is placed in a sloping position. In practice it has become apparent, therefore, that once the moisture has flown out through the openings 4, said moisture no longer tends to flow back through the openings 4, partly because of the viscosity of the moisture and the large capacity of the recesses, not even when the dish is turned upside down.

[0035] Another factor which is conducive to this phenomenon is the fact that the dishes are manufactured in a mould of EPS hard foam, as a result of which the dish surface obtains a structure in which the moisture is retained to a certain extent, this in contrast to the conventional dishes, which generally have a very smooth surface.

[0036] Generally this will not be necessary, if desired, however, an additional layer 10 of an absorbing material may be provided above the impervious foil 9, as is illustrated in Figure 4, for those cases in which it is to be expected that a particularly large amount of moisture will be exuded by the food products to be contained.

[0037] The dish shown in Figures 5 - 8 comprises a bottom 11 and side walls 12 sloping upwards towards the outside from the bottom 11. A number of ribs 13 slightly projecting from the bottom are provided on the upper side of the bottom.

[0038] Near the centre of the dish a large number of openings 14 extending through the bottom are provided in the bottom of the dish, whereby said openings are configured in such a manner that the cross-section of an opening 14 gradually increases in downward direction, as will be apparent in particular from Figures 7 and 8.

[0039] As is furthermore apparent from Figure 7, recesses 15 provided in the bottom side of the bottom connect to the lower ends of the openings 14 located nearest the long sides of the substantially rectangular dish, said recesses extending from the openings 14 in question in the direction of the nearest side walls 12.

[0040] Further openings 16 corresponding with the openings 14 and extending through the bottom are provided near the sides of the bottom, one of said openings 16 being located near each corner point of the bottom 11. Each of said openings 16 opens into a substantially rectangular recess 17 provided in the bottom. The recesses 17 are separated from each other by boundary ribs 18 extending perpendicularly to the boundary edges of the bottom and forming part of the bottom.

[0041] As will furthermore be apparent from Figure 6, each recess 17 is divided into two parts by two ribs 19 extending into said recess, said parts being in communication with each other through a narrow passage 20, which is bounded by the free ends of the ribs 19. The ribs 19, which are provided in the recesses located near the corner points of the bottom, extend perpendicularly to the boundary edges of the bottom in the illustrated embodiment, as will be apparent from Figure 6. The ribs 19 in the other recesses 17 slope towards each other from their ends joining the boundary ribs 18, in a direction remote from the nearest boundary edge of the bottom. The inner boundary walls of said recesses comprise two parts 21 and 22 including an obtuse angle with each other.

[0042] The various openings and recesses provided in the bottom of the dish are closed at the bottom side of the dish by means of a preferably translucent foil 23 attached to the bottom side of the dish, which foil is impervious to liquid.

[0043] When using the dish foodstuffs, such as for example meat, will be placed on the bottom of the dish. Any moisture issuing from these foodstuffs can flow through the openings 14 and 16 and be caught in the recesses 15 and 17 respectively.

[0044] Since the dishes are often placed on a sloping surface, for example in counters or the like, in order to show the food products on the dishes in the best possible manner, the greater part of the moisture will thereby tend to flow into the recesses 17 through openings 16 provided near one side of the dish. When the dish is moved, for example by a customer who wants to have a look at the food products from close by, liquid flown into parts of the recesses 17 located near the boundary edges of the bottom of the dish through the openings 16 can flow into the second parts of said recesses 17 through the passages 20. The obtuse-angled configuration of the boundary walls 21, 22 of the recesses located opposite the openings 16 is thereby conducive to the liquid flowing out from the openings to the second parts of the recesses 17 behind the ribs. It will be apparent that the ribs 19 will thereby oppose any subsequent flow-back of the liquid from the second parts of the recesses in the direction of the openings 16. In this manner a dish having a large capacity for containing liquid in the recesses 17 has been obtained, which recesses are in communication with openings 16 provided near the sides of the bottom of the dish, whilst the flow-back of at least part of the liquid contained in the recesses 17 in the direction of the openings 16 which open into the respective recesses is opposed as a result of the provision of the ribs 19 in said recesses.

[0045] It stands to reason that variants and/or additions to the above-described construction are conceivable within the spirit and scope of the invention.

[0046] Thus Figure 10 shows an embodiment wherein the facing ends 19' of the ribs provided in a recess 17 extend parallel to each other for some distance.

[0047] Figure 12 shows an embodiment wherein the ribs 19, which are provided in a recess 17 located in a corner point of the bottom of the dish do not extend perpendicularly to the boundary edges of the rectangular bottom, but slope towards each other at an angle with respect to said boundary edges.

[0048] Figure 13 shows an embodiment wherein four ribs 24 are provided in a recess 17, each of said ribs extending from a boundary edge 25 of the recess 17 in a direction perpendicular to said boundary edge, and subsequently turning off in the direction of a further boundary edge joining said boundary edge 25.

[0049] As was also set forth with regard to the first embodiment, the dish is preferably manufactured in a mould of EPS hard foam, as a result of which the dish surface obtains a structure in which the moisture is retained to a certain extent.

[0050] In some cases it may also be advantageous to have the foil 9 (Figures 1 - 4) or the foil 23 (Figures 5 - 13) continue upwards from the bottom along the outer sides of the side walls, up to the upper side of the dish in question.

[0051] Figures 14 - 16 show a further embodiment of a dish of expanded polystyrene according to the invention. Also in this case the dish is provided with a bottom 26 and side walls 27 extending upwards from the bottom. Cam-shaped parts 28 projecting from the upper side of the bottom join the inner sides of the side walls.

[0052] A large number of openings 29 extending through the bottom 2 are provided in the bottom 2 in a similar manner as in the preceding embodiments, the cross-section of said openings gradually increasing from the top towards the bottom.

[0053] Near the centres of the short sides of the dish rectangular recesses 30 are provided in the bottom side of the bottom. Said recesses are in communication with a number of openings 31 extending through the bottom, which openings open into the recesses 30 near the edges of said recesses 30.

[0054] It will be apparent that also in this embodiment a recess 30 is able to contain a large amount of moisture, so that also with this dish the above-described effect of the construction according to the invention will be obtained.

[0055] Furthermore it will be apparent that it will be conceivable to have a combination of recesses and openings according to the various above-described embodiments illustrated in the Figures in one single dish.

[0056] Although recesses extending over a comparatively large area are provided in the various embodiments, it will suffice in many cases to provide only openings such as for example the openings 4 or 29, which have a cross-section that is wider near the bottom end of the opening than near the upper end, so that in that case the lower parts of the openings connecting to said openings form the liquid-receiving spaces.
