Description

[0001] TITLE: KIDS’ DINING PLATE UNIT FOR EXTRA WARM EATABLES

[0002] FIELD OF INVENTION

[0003] The present invention relates to a dining plate for holding solid food and eatables thereon, and particularly plate for holding extra warm solid food and eatables. The present invention more particularly relates to dining plate for kids for holding extra warm solid food and eatables.

[0004] BACKGROUND

[0005] Warm food and eatables including roti, paratha including stuffed paratha, poori, potato ball (tikki) and such Indian home made solid food is an all-time liking of children. Extra warm food, served straight from the stove is a common privilege in homes of Indian origin. Fries, Tofu and such continental food likewise is generally served extra warm. Such extra warm food is sometimes too hot for particularly kids and at the same time, it is challenging for parents to make sure that kids do not harm themselves in any way. Plates made of insulating material, though thermally safe for kids to carry, do NOT rapidly bring down food’s temperature to eat ability level. Such plates are also NOT necessarily healthy for handling extra warm food as they might release toxic fumes!

[0006] Noteworthy that tongue and mouth of adults can handle extra warm food and thus they can eat extra hot food while kids neither have such competence nor liking. Adults needs are on the other hand strikingly different, which is to keep the food as warm as cooked for as long as they eat!

[0007] CN213075264U discloses a stainless steel bowl with a heat insulation sleeve sleeved on the outer side of the stainless steel bowl body, wherein a hollow channel is arranged inside the side wall of the heat insulation sleeve, with an objective to keep the food warm, while handling the bowl is safe from getting scalded. In short, this disclosure focusses on needs of adults.

[0008] CN209547682U discloses a bowl tool for scalding food cooling, the bowl wall of the bowl tool uses double layer hollow structure, filling conductive powder including aluminum powder or copper powder. The present invention is focused on needs of kids. Kids generally imitate adults who are generally eager to take a bite of the food as warm as possible! However, for kids, such eating is likely to scald their tender skin in the mouth and a couple minutes of cooling down is necessitated.

[0009] The present invention meets this scientific requirement specific to kids, with fun and interest.

[0010] OBJECTS OF INVENTION

[0011] It is an objective of the present invention to invent a food plate which takes away heat from extra warm food on the plate in a simple manner.

[0012] It is another objective to invent a food plate which engrosses the kid and leads him / her to be patient with the warm food.

[0013] Yet another objective is to invent a food plate which is easy to clean particularly with respect to greasy and oily extra warm food.

[0014] Yet another objective is to invent a food plate which is made of non-toxic material.

[0015] Yet another objective is to invent a food plate which is easily disposable.

[0016] An important objective of the present invention is to invent a food plate which is fun fully safe for kids while they carry and enjoy warm food.

[0017] SUMMARY OF INVENTION

[0018] The present invention is a dining plate unit comprising a carrier plate, an insulating bowl, a convection fortifying assembly. The carrier plate in the preferred embodiment is made of copper but it can be also of copper alloys, silver, silver alloys. The carrier plate has an uneven surface at least on an upper side. The uneven surface is formed by providing several, random or patterned, and mutually spaced raised constructions, while a plurality of air vents are created in-between the raised constructions. When an extra warm flat food like a paratha, or a bread slice is put on the carrier plate, the food largely rests on the raised constructions and thus the raised constructions ensure that the air vents are not blocked by flat face(s) of food, which are crucial for induced convention currents.

[0019] The insulating bowl is made of wood, any engineering plastic including any thermoplastic, or any thermally insulating material. The insulating bowl has a space to house a convection fortifying assembly. A plurality of inlet openings are provided all around its side surface facing the atmosphere. Such inlet opening may also be provided on a bottom surface. The inlet openings along with the air vents and the convection fortifying assembly are an important constituent creating the induced convection current in the present invention.

[0020] The convection fortifying assembly has several embodiments. A first embodiment of fortifying convention assembly, comprising a plurality of inclined blades and a fixation construction. The plurality of inclined blades are constructed around an outside of a hollow cylindrical bridge. The preferred embodiment has at least a pair of inclined blades with twisted construction in an opposite direction. The fixation construction in the preferred embodiment is a through threaded hole provided on the cylindrical surface, having internal screw threads suitable for M3 or M4 or equivalent BS screws. Such plurality of inclined blades are axially assembled by slipping its hollow cylindrical bridge on a rotatable orthogonal shaft disposed in the insulation bowl below the carrier plate. A fixation screw (not shown) is disposed in the through threaded hole and tightened against the rotatable orthogonal shaft. The rotatable orthogonal shaft rotates with minimum air thrust due to a friction-free anchoring of a lower end of the orthogonal shaft in a receptacle of the insulating bowl. A unidirectional rotating force, known as a “couple” is generated when a flow of air or any fluid is directed towards the pair of inclined blades from outside. The air above as well as below the warm food gets warm and moves upwards, causing a pressure differential between an inside of the insulating bowl and an outside of the insulating bowl, resulting into an inward pull from the inside of the insulating bowl from inlet openings. Air entering from inlet openings passes though the pair of inclined blades and creates a rotational movement consequent to the “couple” generated, which further augments induced convection current. Such augmented air flow speeds up cooling of the extra warm food. The moving air also cools the carrier plate, which in turn collects further heat energy from the warm food, through an improved conduction process.

[0021] To further strengthen induced convention current, the convection fortifying assembly further comprises a spiral -spring, a gear combination, a turn-key shaft.

[0022] The turn-key shaft connects with the orthogonal shaft through the gear combination and extends out of the insulating bowl through an orifice or one of the inlet openings. The gear combination facilitates change of direction of rotation from the turn-key shaft to the orthogonal shaft; and also facilitates an alteration in rotational speed of the orthogonal shaft as suitable. A far end of the turn-key shaft has a pair of extensions suitable for turning manually by a thumb and a finger, thereby rotating the turn-key shaft. The spiral -spring has an outer end anchored at the insulating bowl while an inner end is trapped in a slot on the twist key shaft.

[0023] When the pair of extensions is turned in say a clockwise direction, the spiral spring gets tightened till its overall diameter has reached a compacting limit and an adult or a grown up kid can comfortably turn the pair of extensions. On releasing the pair of extensions, the turn-key shaft rotates in an opposite direction due to the spiral spring uncoiling itself, causing the orthogonal shaft to also rotate, at a rotational speed dictated by an uncoiling rate of the spiral-spring, which in turn depends on mechanical parameters of coil material. The inclined blades thus produce a fanning effect. In the preferred embodiment an uncoiling time of 2 to 4 minutes is optimal for current invention. So, with this embodiment, a further strengthened and induced convection current brings down the temperature of the food closer to the room temperature more rapidly.

[0024] To effectively engage the child, an audio chime arrangement is introduced, comprising a multi-striker having a plurality of springy striking arms at a prescribed pitch distance, and a chime drum having a through inner hollow tubular passage and a plurality of projections. The plurality of projections are spread on the chime drum in consonance with a melody tune. A chime sound is produced as every projection causes a rise and a springy fall back on a surface of the chime drum, thereby hitting the surface like a drum stick. A continuous rotation of the chime drum on the orthogonal shaft produces the melody tune. The melody tune for 2 to 5 minutes is effective in keeping kids engaged and digressed for this time for the warm food to come down to a reasonable temperature with respect to the room temperature.

[0025] Instead of a manual arrangement, a mini motor may be provided, with or without a timer circuit.

[0026] Importantly, the carrier plate, being of high thermal conductivity becomes warm and becomes a safety hazard for kids if it comes in contact with kids hands while they hold the dining plate unit with warm food thereon. To obviate such an unwanted situation, an outer top peripheral surface of the carrier plate has an inclination commensurate with the inner top peripheral surface of the insulating bowl such that when the outer top peripheral surface of the carrier plate sits on the inner top peripheral surface of the bowl, a bowl circumferential edge is above the plate circumferential edge, and the carrier plate is fully shrouded and out of reach of the kids. At the same time, the carrier plate is liftable from its place, by an adult, and therefore cleanable, manually and in dish washers. For the adult, a supervisory access arrangement may be provided, comprising a small accessing space provided between the periphery of the carrier plate and the periphery of the insulating bowl, through which the adult may insert a sharp object like a knife to fittingly get the carrier plate out of the insulating bowl. This supervisory access arrangement is made sufficiently difficult for kids.

[0027] As another embodiment, where the carrier plate is not of conducting material, and is particularly a disposable plate then a peripheral part of the carrier plate overhangs outside the top peripheral part of the insulating bowl and can be easily lifted away by kids and disposed of.

[0028] As yet another embodiment, where the carrier plate is not of conducting material, and is particularly a disposable plate for toddlers, then a peripheral part of the carrier plate overhangs around the top peripheral part of the insulating bowl and can be easily lifted away by kids and disposed of, while the carrier plate by itself cannot easily fall away from the top insulating bowl, and the dining plate unit is therefore safe for toddlers.

[0029] The present invention is thus an effective technical solution towards safety of kids including toddlers with respect to extra warm food, particularly of India.

[0049] The present invention shall now be described with the help of drawings. The contents should not be construed to limit the invention in any manner, other than as claimed.

[0050] Figure 1, the present invention is a dining plate unit (100) comprising:

[0051] A carrier plate (80)

[0052] An insulating bowl (30)

[0053] A convection fortifying assembly

[0054] Figure 2, the carrier plate (80) in the preferred embodiment is made of copper but it can be also of copper alloys, silver, silver alloys. Copper and silver are known best conductors of heat and are also considered materials whose nano intake in food (90) is healthy for mind and body. Copper and silver are much healthier and non-toxic in comparison to steel including stainless steel etc.

[0055] Copper and silver wares are known to suck and absorb heat of the contents very quickly and become warm themselves, which helps cool down the food (90) but the plate itself becomes unsafe for kids. This unsafe situation is obviated as explained later and can be seen in Figure 1.

[0056] Present invention exploits benefits of conduction and induces convection currents by inventive construction of the carrier plate (80), thereby further enhancing cooling and also conduction to some extent. Figure 2, the carrier plate (80) has an uneven surface at least on an upper side. The uneven surface is formed by providing several, random or patterned, and mutually spaced raised constructions (84), while a plurality of air vents (82) are created in-between the raised constructions (84). Figure 3, When an extra warm flat food (90) like a paratha, or a bread slice is put on the carrier plate (80), the food (90) largely rests on the raised constructions (84) and thus the raised constructions (84) ensure that the air vents (82) are not blocked by flat face(s) of food (90), which are crucial for induced convention currents. Figure 4, the insulating bowl (30) is made of wood, any engineering plastic including any thermo-plastic, or any thermally insulating material. The insulating bowl (30) has a space to house a convection fortifying assembly, explained later. A plurality of inlet openings (32) are provided all around its side surface facing the atmosphere. Such inlet opening may also be provided on a bottom surface. The inlet openings (32) along with the air vents (82) and the convection fortifying assembly are an important constituent creating the induced convection current in the present invention.

[0057] Let us first understand the process of hot food (90) getting colder on its own, which the present invention augments.

[0058] Figure 5, any hot food (90) on any commonly available prior art plate slowly reduces in its temperature due to air coming in contact with its open surface and taking away some heat energy. By blowing air from mouth, as a mother would do for her kid’s food (90), this process of food (90)’ s temperature reduction slightly speeds up. However, a bottom face of the food (90) does not come in contact with such still or blown air.

[0059] Figure 5A, by providing the raised construction (84), a plurality of air passages (76) are created between the hitherto hidden face of the warm food (90) and the carrier plate (80), and the air thus present therein also gets warm and moves away, filling in with air from surrounding as a replacement, thus a mild air current is induced only by the raised construction.

[0060] Figure 6, the inventive air vents (82) provide a shortened path to the surrounding air to gush in the plurality of air passages (76) and the process of the induced convection current as shown by thick arrow lines get fortified due to the inventive carrier plate (80). The convection fortifying assembly has several embodiments.

[0061] Figure 7, is a first embodiment of fortifying convention assembly, comprising a plurality of inclined blades (54) and a fixation construction. Term “blade” implies thin flat sheet. The plurality of inclined blades (54) are constructed around an outside of a hollow cylindrical bridge (55). The preferred embodiment has at least a pair of inclined blades (54) with twisted construction in an opposite direction. The fixation construction in the preferred embodiment is a through threaded hole (52) provided on the cylindrical surface, having internal screw threads (not shown) suitable for M3, M4, M5 or M6 or equivalent BS screws. Such plurality of inclined blades (54) are axially assembled by slipping its hollow cylindrical bridge (55) on a rotatable orthogonal shaft (56) disposed in the insulation bowl below the carrier plate (80). A fixation screw (not shown) is disposed in the through threaded hole (52) and tightened against the rotatable orthogonal shaft (56). The rotatable orthogonal shaft (56) glidingly rotates with minimum air thrust acting on the plurality of inclined bladed due to a friction-free anchoring a lower end (57)of the orthogonal shaft (56) in a receptacle (34) of the insulating bowl (30). The friction-free anchoring is attained by using materials of low co-efficient of friction for the orthogonal shaft (56); and by precision drilling or surface machining of the receptacle (34) and the lower end (57) of the orthogonal shaft, so that the receptacle is a circular hole to receive the circular orthogonal shaft (56) with a bare minimum air clearance there between. Friction-free anchoring is comparable to we skidding on ice! The friction-free anchoring is crucial to the plurality of inclined blades (54) moving with minimal air flow, analogous to a wind turbine, however without using any bearing or lubrication, thereby keeping the bowl free of any non-edible contamination or contamination catching fluid.

[0062] A unidirectional rotating force, known as a “couple” is generated when a flow of air or any fluid is directed towards the pair of inclined blades (54) from one side. The air above as well as below the warm food (90) gets warm and moves upwards, causing a pressure differential between an inside of the insulating bowl (30) and an outside of the insulating bowl (30), resulting into an inward pull from the inside of the insulating bowl (30) from inlet openings (32). Air entering from inlet openings (32) passes though the pair of inclined blades (54) and creates a rotational movement consequent to the “couple” generated, which further augments induced convection current. Such augmented air flow speeds up cooling of the extra warm food (90). The moving air also cools the carrier plate (80), which in turn collects further heat energy from the warm food (90), through an improved conduction process due to induced convection around the carrier plate (80).

[0063] The present invention thus inventively uses heat energy of the warm food (90) itself to cool down the warm food (90)! Figure 8, to further strengthen induced convention current, the convection fortifying assembly further comprises:

[0064] A spiral-spring (60)

[0065] A gear combination (58)

[0066] A turn-key shaft (70)

[0067] The turn-key shaft (70) connects with the orthogonal shaft (56) through the gear combination (58) and extends out of the insulating bowl (30) through an orifice or one of the inlet openings (32). The gear combination (58) facilitates change of direction of rotation from the turn-key shaft (70) to the orthogonal shaft (56); and also facilitates an alteration in rotational speed of the orthogonal shaft (56) as suitable.

[0068] A far end of the turn-key shaft (70) has a pair of extensions (72) suitable for turning manually by a thumb and a finger, thereby rotating the turn-key shaft (70). The spiral - spring has an outer end (62), Figure 8A, anchored at the insulating bowl (30) while an inner end (64) is trapped in a slot on the twist key shaft.

[0069] When the pair of extensions (72) is turned in say a clockwise direction, the spiral spring (60) gets tightened till its overall diameter has reached a compacting limit and an adult or a grown up kid can comfortably turn the pair of extensions (72). On releasing the pair of extensions (72), the turn-key shaft (70) rotates in an opposite direction due to the spiral spring (60) uncoiling itself, causing the orthogonal shaft (56) to also rotate, at a rotational speed dictated by an uncoiling rate of the spiral-spring (60), which in turn depends on mechanical parameters of coil material. The inclined blades (54) thus produce a fanning effect. In the preferred embodiment an uncoiling time of 2 to 4 minutes is optimal for current invention. So, with this embodiment, a further strengthened and induced convection current brings down the temperature of the food (90) closer to the room temperature more rapidly.

[0070] It is understood that kids need to be engaged or digressed for a couple of minutes so that the food (90) cools down to a safer temperature. To effectively engage the child, an audio chime arrangement is introduced, Figure 9, comprising:

[0071] A multi-striker (46), made of spring steel, having a plurality of springy striking arms (45) at a prescribed pitch distance (40), Figure 9A

[0072] A chime drum (41), Figure 9B, made of a metallic material, having a through inner hollow tubular passage and a plurality of projections (42). The plurality of projections (42) are at the prescribed pitch distance (40) axially and in as many circles (43) as the number of springy striking arms (45). The plurality of projections (42) are spread on the chime drum (41) in consonance with a melody tune.

[0073] The chime drum (41) is disposed firmly on the orthogonal shaft (56) by slipping the chime drum (41) interferingly on the orthogonal shaft (56). The multi-striker (46) is firmly disposed on a base of the insulating bowl (30) vertically, in relation to the chime drum (41) such that each circle (43) of the plurality of projections (42) passes from below the corresponding striking arm (45). A chime sound is produced as every projection (42) causes a rise and a springy fall back on a surface of the chime drum (41), thereby hitting the surface like a drum (41) stick. A continuous rotation of the chime drum (41) on the orthogonal shaft (56) produces the melody tune. The melody tune for 2 to 5 minutes is effective in keeping kids engaged and digressed for this time for the warm food (90) to come down to a reasonable temperature with respect to the room temperature.

[0074] To more effectively engage and digress the kids, the melody tune produced is intelligently relatable to some known and popular melody tune. Illustratively, the relatable melody tune could be the popular "twinkle twinkle little star....". Such intelligent co-relation is attained by creating a chime difference in different rise and springy fall of the different springy striking arms (45). The chime difference is creatable in multiple manners and in the preferred embodiment, the plurality of projections are of different height (44). The chime difference is also creatable by each springy striking arm (45) being of different springiness, which in turn is due to each springy arm being of different hardness, thickness or both. The intelligently relatable melody tune is achievable by a corresponding combination of height (44) difference of projections and or springiness of each springy striking arm (45). Figure 10, instead of a manual arrangement, a mini motor / geared motor (66) may be provided, with a switch, with or without a timer.

[0075] Importantly, the carrier plate (80), being of high thermal conductivity becomes warm and becomes a safety hazard for kids if it comes in contact with kids hands while they hold the dining plate unit (100) with warm food (90) thereon. To obviate such an unwanted situation, an outer top peripheral surface (87) of the carrier plate (80) has an inclination commensurate with the inner top peripheral surface (37) of the insulating bowl (30) such that when the outer top peripheral surface (87) of the carrier plate (80) rests against and therefore sits on the inner top peripheral surface (37) of the bowl (30), a bowl circumferential edge (38) is above the plate circumferential edge (88), and the carrier plate (80) is fully shrouded and out of reach of the kids, Figure 4A. At the same time, the carrier plate (80) is liftable from its place, by an adult, and therefore cleanable, manually and in dish washers. For the adult, a supervisory access arrangement may be provided, comprising a small accessing space (89) provided between the periphery of the carrier plate (80) and the periphery of the insulating bowl (30), through which the adult may insert a sharp object like a knife to fittingly get the carrier plate (80) out of the insulating bowl (30). The small accessing space (89) is created by a local reduced wall thickness of the carrier plate (80) or the insulating bowl (30) or both. The supervisory accessing arrangement is important to remove the carrier plate (80) for cleaning. This supervisory access arrangement is made sufficiently difficult for kids.

[0076] Figure 11, as another embodiment, where the carrier plate (80) is not of conducting material, and is particularly a disposable plate then a peripheral part (81) of the carrier plate (80) overhangs outside the top peripheral part of the insulating bowl (30) and can be easily lifted away by kids and disposed of.

[0077] Figure 12, as yet another embodiment, where the carrier plate (80) is not of conducting material, and is particularly a disposable plate for toddlers, then a hanging part (83) of the carrier plate (80) overhangs around the top peripheral part of the insulating bowl (30) and can be easily lifted away by kids and disposed of, while the carrier plate (80) by itself cannot easily fall away from the top insulating bowl (30), and the dining plate unit (100) is therefore safe for toddlers. Figure 13.

[0078] The present invention is thus an effective technical solution towards safety of kids including toddlers with respect to extra warm food (90), particularly of India and Indian origin. The present invention provides an economical and affordable solution, at the same time promoting use of reusable hygienic plate keeping sustainability of mother earth at the backdrop. Term food (90) and eatables (90) are used interchangeably.
