Description

mth ‘JIWQ1? n^ojw 'khcn 'hno th i hh Single-use Self-contained Extinguishable Apparatus for Cooking Foodstuff Single-use Self-contained Extinguishable Apparatus for Cooking Foodstuff Technical Field The present invention pertains to an apparatus for cooking foodstuff. In particular, the present invention pertains to a self-contained, charcoal based, extinguishable apparatus for roasting or broiling foodstuff, in particular meat products, and a method of using such apparatus.

Background Roasting is basically a method of cooking usually meat over outdoor, open pits of coals. This method has gained a growing popularity since its introduction to the modem lifestyle, and therefore experienced a variety of apparatuses and devices for better, easier and cleaner cooking. For example, electrically operated devices, devices with improved configurations for containing charcoal and roasting meat are offered beside the yet popular simple shallow metal container covered with a metal grid. These, however, still require introducing the heat source, i.e. charcoal briquettes, into the device and igniting it cleanly and easily without significant trouble. The general solution, which complements the roasting devices, is one-time use, portable containers containing charcoal briquettes and made of extinguishable material, usually cardboard.

Charcoal briquettes may be provided either as pieces of natural wood or synthetically made from a very dense aqueous mixture of ash. The latter is less favorable due to its greater content of water, which brings about a longer time of setting fire to the heat source.

US 6,328,028 describes a portable, combustible fuel container made of a one-piece carton blank, which houses charcoal. A firestarter is placed separate from the charcoal, allowing direct access to the firestarter for its removal from the container. Deployable legs raise the container off of a surface for placement of the firestarter under the package and allow air flow to the base of the container to maintain the burning of the firestarter and charcoal material inside the container.

WO 01/67936 describes a cardboard cuboid packaging made of two halves that combines an igniter and chimney for igniting solid fuel such as charcoal. The charcoal is housed in the packaging and the chimney runs through the packaging from one end to the other and forms an integral part of it.

A packaging for igniting charcoal known as Grillcube comprises a cardboard box with air flue and cardboard wick, i.e. chimney, in the middle.

US 7,670,392 describes a disposable and combustible container that houses a charcoal-based heat source and includes co-axial inner and outer chimneys structure. The outer chimney envelopes the inner chimney, where the inner chimney allows air flow inside for igniting the charcoal and the outer chimney expels combustion fumes outside the container through a plurality of holes in its top base. The container also has a top cover secured to the chimneys and flaps, which provide the first ignition starter material.

US 2009/0277438 describes a charcoal igniting cylindrical modular container having lower and upper bases, surrounding round wall, a chimney inside it, holes in its lower part for allowing air flow inside and holes in its lower base for contacting an ignition source. The sidewall of the chimney is covered with wax.

US 2008/000467 describes a portable, disposable paperboard container for lighting charcoal. The container comprises a main body and a tube situated in its center co-axially relative the container walls. The tube houses an ignition strip, which when ignited lights the charcoal in the container. The container eventually burns away, living only a burning charcoal pile.

All the apparatuses and devices described above suffer from part or all of the following deficiencies: the charcoal is in contact with the interior side of the walls of the container, which causes the walls to heat up before complete combustion, making it very difficult to handle the container after ignition; a significantly excess amount of cardboard is wasted in providing a closed volume for containing the charcoal; the container have high walls protruding out and above the walls of the roasting device. This increases the chances for unintentional and uncontrollable fire hazards, resulting from burning cardboard pieces carried away by incidental air waves. Such fire hazards are intensified when lighting such containers in an open field usually populated by relatively easily burning materials such as woods and bushes. In this respect, negative environmental consequences due to the scattering of burned cardboard residues are also ignored.

Further, several variables, which influence the efficiency and quality of the process of starting the fire and keeping the heat source, are not considered in the solutions provided in the prior art. Such variables are the minimum amount of charcoal required for providing sufficient heat source for roasting, the total volume of charcoal relative to the capacity of the container or in other words the free volume within the container, the radial distance between the chimney and the inner walls within the container, the minimum volume of container required for carrying charcoal and the strength of the minimum volume of the container sufficient for safely carrying a selected weight of charcoal.

The prior art essentially does not challenge these variables, and thus only provides particular solutions, which in turn create other problems.

Objectives The objective of the present invention is to provide an overall solution for a single-use, self-contained, extinguishable, combustible charcoal container for placing in roasting devices. Such solution takes into account all of the variables detailed above for constructing a container with optimal efficiency of a charcoal-based heat source for roasting devices.

Still another objective of the present invention is to provide particular apparatuses for single-use, self-contained, extinguishable, combustible charcoal container, which responds to the variables detailed above and deficiencies of the prior art.

Still another objective of the present invention is to provide a charcoal container, which enables easy, safe and quickly operable fire setting for roasting foodstuff in roasting devices.

Still another objective of the present invention is to provide a construction of charcoal container that is adaptable to the dimensions of any roasting device. In particular, such construction of charcoal container is adapted not to protrude out and above the walls of a roasting device.

Still another objective of the present invention is to provide a charcoal container that reduces fire hazards and contamination of the environment by preventing the scattering of burned pieces of the container out of the boundaries of the roasting device.

Still another objective of the present invention is to provide a charcoal container, which employs all parts of the container in an efficient way oriented toward setting fire to the charcoal and keeping it during roasting of foodstuff.

Still another objective of the present invention is to provide a charcoal container that reduces the amount of initial material required for setting fire in the charcoal.

Still another objective of the present invention is to provide a method of applying such containers.

These and other objectives and details of the present invention will become apparent as the description proceeds.

Summary of the Invention In one aspect, the present invention provides single-use, self-contained, combustible, extinguishable, charcoal container for placing in roasting devices, where the container is modular and contains an amount of charcoal required for providing sufficient heat source for roasting, a free volume within the container, which defines air insulation of at least part of the inner walls of the container from heat emitted from the charcoal, a selected radial distance between the inner walls and at least one chimney located within the container, where the selected radial distance of the chimney from the inner walls of the container and the total volume of the container set the amount and configuration of the charcoal, which can be accommodated within the total volume of the container without falling out of it upon separating the parts of the container from each other, where the strength of the weakest areas of the container is sufficient for safely carrying a selected weight of charcoal within the container.

The container as defined above fulfills the objectives of the present invention by keeping an optimal balance between the maximum amount of charcoal that it can be loaded with and its comfortable and safe use. As will be described and illustrated further in the description, the inner construction of the container enables such balance. This construction essentially comprises walls divided to lower and upper portions and at least one chimney within the container. These parts of the container provide the configuration, which is required to keep a stack of charcoal briquettes concentrated around the chimney and only partially relying on the walls of the container for balance. Thus, when the upper portion of the walls is separated from and lifted off of the lower portion of the container, the charcoal briquettes maintain their position stacked around the chimney or chimneys without falling outside the boundaries of the lower portion. This configuration also isolates the upper part of the upper portion from the heat accumulated in the stack of charcoal. This maintains the upper portion of the container manageable for lifting off after ignition and heating up of the charcoal take place.

The advantage imparted by such construction of the container is twofold: first, providing a closed volume for containing the heat accumulated in the stack of charcoal briquettes; second, retaining only the minimum amount of extinguishable, combustible material, from which the container is made, for initiating and maintaining fire in the charcoal.

In accordance with the above, in one preferred embodiment, the present invention provides a single-use, self-contained, extinguishable, combustible charcoal container for placing in roasting devices, which comprises a lower base portion, an upper portion, where the lower base portion and the upper portion are connected to each other, where the border between the lower base portion and the upper portion is defined by a perforated line of weakening surrounding the perimeter of the container, which enables separating the upper portion from the lower base portion, at least one chimney within the volume of the container defined by the connected lower base portion and the upper portion, the chimney extending from the lower base portion through the volume of the container and meets a top cover of the container, where the top cover is connected to the upper edges of the upper portion with a perforated line of weakening, at least two legs connected to the lower base portion at the exterior surface of the bottom of the lower base portion, where the lower base portion comprises concealed openings in its sides, the border of the concealed openings is defined with a perforated line of weakening.

In still another preferred embodiment, the container is made of a single piece of material having defined edges for each part, and is foldable and deployable around these edges. In particular, the sidewalls of the container are defined from each other by neighboring edges that retain the continuous material except for the two opposing outer edges. In order to form a closed space of the container, these two opposing outer edges are connected to each other with a connecting adhesive, where the connecting adhesive is absent from the perforated line of weakening, which surrounds the perimeter of the container.

In still another embodiment, the chimney defines an inner configuration within the container, providing support for assembling charcoal briquettes around the chimney and a free insulating volume between the stack of charcoal briquettes and the inner side of the walls of the upper portion of the container.

In still another embodiment, the lower and upper portions of the walls of the container, corresponding to the lower and upper portions of the container, are designed with such dimensions relative each other in order to obtain two goals: first, to provide the minimum amount of starting material required to set fire to the charcoal; second, to provide sufficient structural strength to carry maximum weight of charcoal within the container.

To ensure that the second goal is obtained, in still another embodiment, the container is provided with a double layer bottom surface to enable it supporting a maximum stack of charcoal briquettes. Essentially the inner of the two layers does not depend or rely on the continuous construction of the container, thus imparting a greater strength to the container for carrying weight load. Further, as will be explained, the double layer bottom surface is also intended to prevent falling of ashes generated during burning out of slits created at the corner areas from which legs extend out of the container.

In still another embodiment, the container comprises a plurality of chimneys within its volume, where the chimneys provide enhanced support for an assembly of charcoal briquettes and definition of the free insulating volume between the stack of charcoal briquettes and the inner side of the walls of the upper portion of the container.

In still another embodiment, the upper cover of the container may be released from the walls of the container by disconnecting it along a perforated line of weakening, which forms the defining edge that borders the upper edges of the walls. This imparts a further advantage, since the upper cover may be used as a hand-held fan to induce, accelerate and maintain burning of the charcoals after ignition and removal of the upper portion of the container. The modularity of the upper cover absolves the user from requiring other means intended to maintain the fire in the charcoal during roasting of foodstuff.

In still another embodiment, the sides of the chimney comprise holes configured to allow air flow inside the chimney.

In still another embodiment, the present invention provides a container where the lower base portion comprises holes in at least part of the faces of said lower base portion, where the holes are concealed by a cover, where the cover is defined by a perforated line of weakening around the circumference of the holes. The holes are exposed by pressing on the cover and releasing it from the face of the lower base portion. These holes allow air flow inside the container, which carries oxygen required for setting and maintaining fire to the charcoal within the container.

In still another embodiment, the container further comprises handles cut out of an upper cover, which closes the container. The border between the handles and the cover may form partial perforated line of weakening, so that the handles can be partially detached off of and remain connected at other parts to the cover. This allows providing a sealed container with no entry areas, which can be easily lifted and carried upon detachment of the handles off of the cover. Further, flaps may be added under the cover, which are connected to the upper edges of the upper portion of the container, optionally with a perforated line of weakening. These flaps enhance the strength of the container and secure its integrity in any case of complete detachment of the cover and/or handles off of the container. The flaps also provide a temporary cover after ignition of the starting material in the chimney. This creates a closed space inside the container which allows heat to be accumulated in the charcoal before exposing it to the environment.

Closing strip-slit coupling may also be added to the cover and wall of the upper side to provide further closing means to the container.

In still another embodiment, the container is foldable to a collapsed configuration.

In still another embodiment, the upper portion of the container is recyclable. In particular and as mentioned above, the upper portion may be used as a hand-held fan for accelerating and maintaining the fire set in the charcoal. This essentially renders the container of the present invention an all-in-one solution, which satisfies all operations needed to be carried out in roasting foodstuffs over charcoal.

The configuration of the container is not affected by its geometrical shape, as long as this shape maintains the dimensions and positions of the components of the container relative to each other. Therefore, the container may be provided, for example, in rectangular, trigonal, hexagonal or octagonal shapes, as long as the dimensions of its lower base and upper portions relative each other are sufficient for carrying an amount of charcoal briquettes, which is sufficient for providing heat for roasting foodstuffs. Further, the walls of the container and the chimney are each of size relative each other, which enables to stack charcoal briquettes around the chimney without the briquettes falling outside the borders of the container upon lifting the upper portion off of the lower base portion. In this respect, the role of the chimney is twofold: to provide inner space for igniting an initial flame within the container and a back rest for the charcoal briquettes. This way, the briquettes are piled on each other, forming a stack that does not lean on the container walls. The upper portion of the container then does not absorb much of the heat accumulated in the charcoal briquettes. This provides sufficient insulation for the container walls, which enables lifting its upper portion off of the lower base portion, after a sufficient time lapsed, and the charcoal briquettes accumulated enough heat.

The above applies also to different configurations with a plurality of chimneys in the container. The relative heights of the lower base and upper portion of the container and the perforated line of weakening between them also play a role in determining the amount of charcoal briquettes that can be loaded in the container. The higher the upper portion is, the more charcoal can be loaded in the container. The walls of the lower base portion should be sufficient to provide minimal support required to form a stack of charcoal briquettes around the chimney. Further, the stronger the base of the lower base portion, the more weight of charcoal can be loaded in the container. Accordingly, in one particular embodiment, the base of the container, which is also the bottom of the lower base portion, comprises a double layer of cardboard. Such double layer enhances the durability of the container to sustain larger weights of charcoal.

In one particular embodiment, the container is made of cardboard, paper or any other combustible, extinguishable material.

In still another aspect, the present invention provides a method of applying a single-use, self-contained, extinguishable, combustible charcoal container to a roasting device comprising: providing a modular container, which comprises a lower base portion and an upper portion, where the lower base portion and upper portion are connected to each other with a perforated line of weakening around the perimeter of the container, which defines the border between them; placing a stack of charcoal briquettes within the container; placing the container on a roasting device; releasing covers concealing holes in faces of the lower base portion; releasing the top portion from the lower base portion; opening an upper cover and flaps of the container and exposing the top portion of at least one chimney located within the container, the chimney extending from the base to the cover of the container; placing a flammable material within the chimney and lighting this material; closing the flaps of the container, retaining only an opening above the chimney; allowing the stack of charcoal briquettes to heat within the container; lifting the upper portion of the container off of the lower base portion; allowing the stack of charcoal briquettes to heat and consume the lower base portion of the container.

The steps of applying the container detailed above substantially shorten the time required to set a stack of charcoal in heat sufficient to roast foodstuffs in a roasting device. All this is done in a safe and clean way that does not require particular knowledge, experience or expertise. In fact, the container of the present invention may be child-proof in the sense that it may be operated and controlled by relatively young people without any risk to their safety. The application of the method of setting fire to charcoal container within the charcoal container of the present invention significantly reduces the time required to set fire to the charcoal. This is due to modular characteristics of the container, which enable adjusting it according to each particular stage of igniting and setting fire to the charcoal.

Detailed Description of the Drawings The following describes non-limiting examples of the present invention with relation to the accompanying drawings.

Figs. 1 and 2 illustrate a schematic a top view of deployed two dimensional configurations of particular examples of containers (1, 2) before folding them to three dimensional configurations. The basic parts of the container are the same in both examples (1, 2). The upper portion of the walls (11) of the container forms a continuous surface with the walls of the lower base portion (12) of the container. The upper portion (11) and lower base portion (12) of the walls form a continuous single piece of material, which is foldable around the edges (11a), which define walls. The perforated line of weakening (14) defines the border between the upper portion (11) and the lower base portion (12). This perforated line of weakening (14) extends throughout the perimeter of the container, enabling the complete release of the upper portion (11) from the lower base portion (12). As mentioned above, each two faces of the lower base portion (12) and upper portion (11) form a continuous single piece of material, which is foldable around the edges, which define the faces. Only the two outer edges (lib, 11c) of the walls are are attached to each other at their interfacing edge with an adhesive upon folding the container to a three-dimensional configuration. However, in order to enable complete and easy release of the upper portion (11) from the lower base portion (12) the interface at the two at the point (14a) where the perforated line of weakening passes is absent of such adhesive. The residual portion (lid) continuing the walls is folded inside when folding the walls themselves to secure the three-dimensional configuration formed.

Holes (12a) located in the lower base portion (12) are initially concealed with cardboard and defined by a perforated line of weakening, which enables conveniently releasing their cover and exposing them. When opened, the holes (12a) allow inflow of air, which carries oxygen for sustaining the fire lit within the container (1, 2). The third basic part of the container (1, 2) is the chimney (13), which is also made of cardboard, preferably integrated with the entire surface, which is used to form the container. The chimney (13) is folded around itself and stands in erect position from the base to the top of the container (1, 2). The chimney (13) also comprises holes (13a) to allow inflow of air that carries oxygen, to allow initial ignition of the flammable material within the chimney (13).

Further, the container (1, 2) comprises a top cover (15), in which two handles (15a) face each other. The handles (15a) are defined on the surface of the top cover (15) by a perforated line of weakening. Pressing on the handles (15a) releases them from the surface of the top cover (15) at the perforated line of weakening, enabling to use them in carrying the container by hand. Trapeze shaped flaps (18a-d) form the double layer base of the container (1, 2). A folding line (18e) in the trapeze shaped flaps (18b, 18d) divides them into two triangles and enables locking the flaps (18a-d) to each other, forming the double layer base. An additional cover beneath the top cover (15) is formed of two parts (19a, 19b) completing each other. Recesses (20a, 20b) in each part (19a, 19b), respectively, define an opening above the top part of the chimney (13). A strip-slit coupling (21) provides further closing to the container. Part (17) provides a base for the chimney (13) with an inner area (17a) on which the chimney (13) is placed. Legs (16) support the container (1, 2) beneath its base and are integrated with it. The legs (16) provide a space between the container (1, 2) and the surface on which it stands, which insulates that surface from the heat accumulated within the container (1, 2) and allows air flow into the container (1) to encourage the setting of fire to the charcoal. Thus, the inflow of air through the space, which the legs (16) form, under the bottom surface of the container (1), enables accelerating the lighting of fire to the charcoal within the container (1). Because the legs (16) extend from the continuous piece of material forming the container (1), they should be cut at the comers of the container, thereby forming slits from which ash and fire debris created inside the container fall outside. This is undesirable, since it generates dirt at the floor of the roasting device. The double layer bottom of the container is used to overcome this problem by providing an additional layer that covers these slits.

The container (1) in Fig. 1 is different from the container (2) in Fig. 2 in accommodating two chimneys (13) within it. Thus, the upper opening is doubled (20a, 20b). So do the bases (17a, 17b) chimneys (13). The addition of a chimney in the container (2) not only accelerates ignition and lighting of charcoal, but also provides further support for the charcoal briquettes stacked within the container (2). Other than these differences, the two configurations of containers (1, 2) operate in essentially the same manner.

Figs. 1A and 3 illustrate a three-dimensional erect configuration of the container illustrated in Figs. 1 and 2. As can be seen, the chimneys (13) are located in the middle of the container (2). The holes (12a) in the lower base portion (12) allow air inflow and oxygen supply to the charcoal within the container (2). The chimneys (13) also contain holes at their outer surfaces, which allow air inflow and oxygen supply to ignite the flammable material inside them and start a fire.

Figs. 4 and 5 show visual demonstration of particular container configurations of the present invention stacked with charcoal. Particularly, Figs. 4A-F show a rectangular elongated container, where the upper portion (11) is larger than the lower base portion (12). Figs. 4A-4D show the container (1) in closed and opened or partially opened positions. Fig. 4A shows the handles (15a) detached from the upper cover. The strip-slit coupling (21) is shown in locked position. Figs. 4B-D show complete and partial opened positions of the container (1). Fig. 4A is a top view showing the inside of the container (1) including the chimney (13). Opening the cover of the container exposes also the flaps (19b) (19a is not shown) having recesses (20b) (20a is not shown). The recesses (20a, b) form an opening above the chimney (13) to allow fluid communication with the environment, letting air flow in and out of the chimney (13). Of particular interest are Figs. 4E-F, which show the detachment of the upper portion (11) off of the lower base portion (12) at the line of weakening (14). It can be seen that the stack of charcoal briquettes (22) does not disassemble when the upper portion (11) is lifted off after release from the lower base portion (12). Fig. 4D shows the dense stack of charcoal briquettes (21) surrounding the chimney (13) after the upper portion (11) is completely lifted off.

Figs. 5A-E show a similar situation to the one shown in Figs. 4A-F but with a shallower two-chimneys container configuration (2). The chimneys (13) provide the support required to stack the charcoal briquettes (21) around them. This stack position of the charcoal briquettes (22) is kept in its integrity even after the upper portion (11) of the container (2) is released and lifted off.

The additional advantage in discarding the upper portion (11) of a container after sufficient time lapsed to allow heating the charcoal in closed space is in accelerating the total burning and combustion of the extinguishable container. This way, much less cardboard should be burned away, therefore much less time is required to arrive at the eventual goal of a stack of hot charcoal for roasting foodstuffs, in particular meat products.

Figs 6 and 7 show triangular and hexagonal shapes of the container. It is clear from these Figures that the functional parts of the container remain the same in both shapes. This essentially exemplifies that the container of the present invention can be designed in any shape in order to fit to any geometrical shape of a roasting device.

Figs. 8A-F visually demonstrate the steps of activating the charcoal container (1, 2). At first stage, Fig. 6A, the holes (12a) at the lower base portion (12) are opened by pressing their covers inside and releasing them at the lines of weakening, which define them. Next, Fig. 6B, the top cover (15) is removed. Afterwards, Fig. 6C, the line of weakening (14) between the upper portion (11) and the lower base portion (12) is pressed, releasing the two portions from each other. A flammable substance is put inside the chimneys (13) and lit (Fig. 6D). The upper openings (17a, 17b) above the chimneys are kept closed for a while until the charcoal within the container (2) accumulates sufficient heat, (Fig. 6E). Eventually, the upper portion (11) of the container is lifted off, the stack of charcoal is exposed and the remaining parts of the container are left to be consumed until complete combustion.
