Food Grade Container
Food grade container with a double wall structure that provides the benefits of insulating the contents from the environment and also serving to enhance the structural rigidity of the item in use. Multiple cavities are formed between the two walls designed to contain an insulating air barrier. The geometric structure of the cavities enhances the structural integrity by providing support for each wall and cushioning movement in one or both walls when constructed of an elastomer.
The present invention relates to food containers and in particular to a food grade container.
The invention has been developed primarily for use in containers for cooking and/or storing of food and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use.
BACKGROUND OF THE INVENTIONCookware and food storage containers are typically manufactured from a range of materials, including such materials as glass, plastic, and metal. However, these materials have notable drawbacks that prevent them from being used in a wide range of settings. In particular, cookware manufactured from metals is not suitable for use in a microwave oven due to arcing, while certain plastics are known to leach toxic compounds such as phthalates or in the case of Teflon, perfluorooctanoic acid, when exposed to heat. In the case when glass is used in cookware, food has a tendency to stick to the glass surface making it difficult to clean.
More recently, silicone rubber has presented itself as a useful material for use in cookware, having properties that enable it to be safely used in microwave ovens, dishwashers, and freezers, as well as being both a food grade and non-stick material. However, silicone rubber suffers from a distinct lack of rigidity, which is particularly noticeable when it is used in such cookware as muffin trays, where distortion of the tray has a tendency to crush the muffins in the wells of the tray. This shortcoming has prompted manufacturers to develop cookware that comprises a silicone rubber/metal hybrid. However, the use of metal prevents the hybrid material from being used in microwave ovens.
The present invention seeks to provide a food grade container, which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative.

It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.
The structure of the side wall 30 comprises a first surface 32, an opposing second surface 35, and a predetermined thickness between the first and second surfaces 32 and 35. The side wall 30 comprises a plurality of webs 70 that extend between the first surface 32 and the second surface 35. The plurality of webs 70 define a plurality of parallel and spaced elongated cavities 60 in the side wall 30. The plurality of elongated cavities 60 extend in between and parallel to the first and second surfaces 32 and 35. The uniform distribution of the webs 70 along the side wall 30 provides the side wall 30 with structural rigidity. The elongated cavities 60 defined by the plurality of webs 70 in this embodiment are circular in cross section.
The side wall 30 is configured in a circular manner such that the first and second surfaces 32 and 35 form the external and internal surfaces, respectively, of the side wall 30. The elongated cavities 60 in the side wall 30 extend vertically from the base 20 to the opening 40. The elongated cavities 60 are distributed substantially uniformly spaced around the side wall 30.
The wall structure of the base 20 is the same as the side wall 30, and includes a first (internal) surface 25 and an opposing second (bottom) surface (not shown). The elongated cavities 60 in the base 20 thus extend generally horizontally.
The side wall 30 in
The uniform distribution of equally sized elongated cavities 60 around the side wall 30 the base 20 of the container 10 provides a uniform distribution of air gaps for insulating the container 10 and any food contained therein in use.
The uniform distribution of the webs 70 affords structural rigidity to the food grade container 10, yet still enables the silicone rubber to retain a degree of pliability. For example, the food grade container 10 is self-supporting and capable of supporting the weight of a food product contained therein. A user removing the food grade container 10 from, for example, an oven or a freezer is unlikely to inadvertently distort the container 10 thereby displacing the hot or cold contents, respectively, from the container 10, and burning themselves in the process. In the case where the food grade container 10 is used for baking a cake or muffin, the pliability of the food grade container 10 is still sufficient to allow a user to easily remove the baked goods from the food grade container 10 without damaging the structural integrity of the baked goods.
In other embodiments, the elongated cavities 60 are not limited to being distributed substantially uniformly, but may be non-uniformly distributed. This arrangement provides non-uniform distribution of webs 70 thereby enabling certain parts of the container 10 to have a greater or lesser structural rigidity than other parts of the container 10.
In other embodiments, the elongated cavities 60 in the side wall 30 of the container 10 are not limited to extending from the base 20 to the opening 50 of the container. For example, the cavities 60 may extend substantially horizontally around the side wall 30.
In other embodiments, the elongated cavities 60 may have any desirable cross section that provides the air gaps for insulating the food grade container 10 and the food contained therein.
In other embodiments, the elongated cavities 60 in the one container may also comprise combinations of different cross sections. For example, in one arrangement, one set of elongated cavities (not shown) may have a circular cross section, and a second set of elongated cavities (not shown) may have a rectangular cross section. Given that elongated cavities with one cross section may afford the food grade container 10 with a greater structural rigidity than elongated cavities with another, it is possible to produce a food grade container 10 in which parts of the food grade container 10 have a greater structural rigidity than other parts, which would be advantageous in embodiments where certain parts of the food grade container 10 need to be more pliable than others.
In other embodiments, the food grade container 10 may comprise insulation (not shown) disposed within each of the plurality of elongated cavities 60 to supplement the existing insulation provided by the air gaps defined by the plurality of elongated cavities 60. For example, the insulation may be a polyurethane foam.
In other embodiments, the container 10 may further comprise a container lid (not shown) to close the container 10 in use. The wall structure of the container lid is ideally the same as the side wall 30, such that the first surface and the opposing second surface of the container lid have the same predetermined thickness with a plurality of parallel and spaced elongated cavities (not shown) therebetween. The container lid may be mounted in any suitable manner to close the food grade container 10. By closing the food grade container 10 with the container lid, the contents within the open volume 50 of the food grade container 10 are further insulated, thereby enabling the temperature of the contents to remain at the desired temperature for longer.
The side wall 30 in
The wall structure of the base 120 and the three side walls 130, 140, 150 of the tray 100 are the same as the sidewall 30 of the food container 10c which has the alternating inverted triangular cavities 60c, given in this embodiment as reference numeral 180. The elongated cavities 180 in the side walls 130, 140, and 150 extend downwardly while the elongated cavities 180 in the base 120 extend horizontally from the open end to the side wall 140.
The side walls 130, 140, 150 and the base 120 in
The tray 200 further comprises eight receptacles 210a to 210h with a general structure similar to the container 10c described above. In this embodiment, however, the corresponding side wall 230a to 230h of each of the receptacles 210a to 210h extends conically upwardly from the corresponding base 220a to 220h to terminate at the opening (not shown) of the corresponding receptacle 210a to 210h to define a generally bowl-like structure. The open volume 240a to 240h defined by the base 220a to 220h and the corresponding side wall 230a to 230h of each receptacle 210a to 210h has a corresponding bowl-like structure for receiving and holding contents therein in use.
The opening (not shown) of each receptacle 210a to 210h is substantially aligned with a corresponding one of the eight apertures 207a to 207h in the body 201 such that the opening engages with the bottom surface 203 of the body 201 at the corresponding aperture 207a to 207h to form an integral attachment to the body 201. The eight receptacles 210a to 210h of the tray 200 are thus arranged in an array format with spacing therebetween. The front edge 206 and the apertures 207 of the body 201 are shown as such in
In other embodiments, the tray 200 is not limited to just eight receptacles 210a to 210h, but may comprise one receptacle (not shown) or more than one receptacle as is desired.
In other embodiments, the body 210 of the tray 200 is not limited to having a generally rectangular configuration, but may take any configuration, including but not limited to: circular, square, oval, triangular, or an irregular configuration.
In other embodiments, the tray 200 is not limited to a tray for baking cakes or muffins as shown in
As shown in
The structure of the side wall 330 comprises an inner layer 332 which defines the first surface, and a generally fluted outer layer 335 which defines the second surface. The outer layer 335 also defines the plurality of cavities of between the inner layer 332 and the outer layer 335. The outer layer 335 defines a plurality of spaced apart elongated grooves 360, which extend upwardly from the base 320 substantially to the opening 340. The elongated grooves 360 are substantially parallel to each other and are distributed uniformly around the side wall 330. The elongated grooves 360 are generally triangular in cross section. The fluted outer layer 335 also defines circumferential contact portions 362 which are generally defined by the peaks of the flutes.
The base 320 can include elongated cavities 360 therein, which can extend generally horizontally.
As shown in
The insert portion 310 is manufactured from an elastomer such as silicone rubber to afford the first body 310 with a wide range of properties including: non-stick, non-toxic (i.e. food grade), resists microbial growth, stain resistant, odour resistant, and heat resistant. The first body 310 being manufactured solely from silicone rubber ensures that it can be safely used in a microwave oven, an oven and a freezer.
As shown in
In use, the insert portion 310 configured to locate within the internal volume of the housing portion 350 such that the contact portions 362 of the insert portion 310 abuts substantially against the inner surface 353 of the housing portion 350. Thus, each of the plurality of grooves 360 will define a plurality of cavities between the inner layer 332 of the insert portion 310 and the housing portion 350.
In other embodiments, only the outer surface 335 of the side wall 330 may be shaped so that it defines a plurality of grooves (not shown). As such, the inner surface 332 of the side wall 330 may be a smooth, continuous surface (not shown).
In other embodiments, the plurality of cavities (not shown) may be distributed substantially non-uniformly around the side wall 330.
In other embodiments, the plurality of grooves are not limited to being generally triangular in cross section as described above, but may instead be generally semi-circular, square, rectangular, or oval in cross section.
In other embodiments, the plurality of grooves in the side wall 330 are not limited to being of the same cross-section, but instead, the grooves (not shown) around the side wall 330 may be comprised of a combination of cross sections.
In other embodiments, the food grade container 300 may further comprise insulation (not shown) such as, for example, polyurethane foam, disposed within each of the plurality of cavities defined between the outer surface 335 of the first body 310 and the inner surface 353 of the housing portion 350.
In other embodiments, the plurality of grooves in the side wall 330 are not limited to extending vertically from the base 320 to the opening 340, but may instead be horizontally or diagonally disposed around the side wall 330.
