Definitions

  • the present invention is related to a tray for sauces. More specifically, the present invention is related to a tray for holding a plurality of servings of sauces, products containing this tray and methods of use of this tray.
  • US Patent No. 1,168,731 discloses a jelly container formed in the shape of a tray, having a number of individual receptacles in which the jellies are deposited and sealed.
  • the base plate is provided with indentations or perforations that provide for easy separation of the receptacles.
  • the tray is formed of a fibrous or analogous material, suitably impregnated so as to render it fit for the storage of jellies.
  • a compartmented container unit is disclosed in US Patent No. 3,520,439, which is formed from a self-supporting but frangible material and comprises a plurality of containers. At least one separation cut is formed between adjacent containers.
  • the container unit may be formed from a plastics material, and advantageously may be moulded from expanded polystyrene.
  • the container unit as shown in this patent has long cuts 6 formed in the container, with the compartments being interconnected by small portions 7 of material.
  • the compartments are releasably secured to one another by means of a pair of lengths of contact adhesive coated tape 8 adhered about the upper peripheral edge portions of the side walls.
  • a food product container is disclosed in U.S. Patent No. 5,786,011, which comprises a central section, peripheral sections and individual cavities to contain small portions of food product.
  • Each cavity of the body overlaps the central section and one of the peripheral sections which are linked via a weakening line permitting detachment of the two sections. The detachment allows for the removal of the food item from the cavity.
  • the line of weakening thus divides the cavity itself, and is not a separation of the cavities that allows for separation of the food items from the multi-portion container without opening the cavity.
  • the present invention provides a multiple portion tray comprising a plurality of receptacles for holding individual servings of sauce.
  • the tray has lines of weakness between the receptacles so that the receptacles do not separate from one another under tensile forces that generally correspond to the amount of force normally imparted to a tray when being conveyed by conventional automated packaging equipment, but which receptacles do separate under tensile force such that the consumer can readily separate the receptacles one from another by using only tensile force.
  • the tray is formed from a rigid foam material.
  • a preferred embodiment of the tray of the present invention has receptacles being connected in the tray by land areas having a width of 1-3 mm and a gap area having a width of 15-30 mm between each land area.
  • Sauce-filled trays and combination products containing the tray and comestible article are also provided. Additionally, methods of making the sauce-filled trays, combination products, and methods of using the combination products are also provided.
  • the tray of the present invention provides substantial benefits to both the manufacturer and the consumer of prepackaged food products. Specifically, the present invention enables a low cost system for packaging sauces in individual portions, whereby such portions may be handled in a bulk manner, yet where the portions are easily available for individual service. From the manufacturing perspective, the tray of the present invention provides easy processability, because multiple individual portions may be handled as a unitary article. Because the tray of the present invention holds together when exposed to certain incidental forces that would tend to separate the receptacles, the tray may be handled by automated processing equipment and conveyed to appropriate destinations for packaging insertion. Further, a unitary tray comprising a plurality of individual portions provides easier handling of the sauce, because a larger tray tends to be easier to mechanically manipulate than smaller individual portions.
  • An added benefit of the unitary tray is the immobilization of individual sauce portions in the package of the combination product comprising sauce portions and comestible articles in the product packaging. Because individual receptacles containing sauce are connected to each other, there is less shifting in the product packaging of items contained therein. The reduction in shifting provides a more consistent product appearance upon opening of the package by consumers, and reduction of product damage (to either the sauce portions or the comestible articles) caused by shifting or instability of items within the combination product package.
  • the unitary aspect of the tray provides significant quality control capabilities of the overall product.
  • the present invention also provides convenience to the consumer, because it is now possible to provide a unitary package comprising both the comestible articles together with a suitable sauce for the comestible article together in a single package location. Because the individual receptacles for holding the sauces are attached to each other, there is less opportunity for sauce receptacles to go missing in the home freezer or other storage location. Additionally, the combination product of the present invention enhances the ability to link any particular sauce with a particular comestible article, thereby providing a unitary and unique product identification. Specifically, the flavor of the sauce may be uniquely matched with the comestible article to provide maximum flavor impact. The present system allows for unique product combinations to be made, and additionally simplifies the matching of the comestible article with the sauce.
  • the present invention is a particular benefit for do-it-yourself serving by children.
  • children find it very gratifying and pleasing to be able to go to a single package to obtain their own food product and assemble this product for consumption by themselves.
  • children seem to be naturally drawn to food products wherein a food article is dipped into an accompanying sauce.
  • the tray of the present invention simplifies this process for children. Because the tray of the present invention is made from a rigid foam material, it is easier to safely handle the sauce-containing receptacle (sometimes referred to as a "dipping cup") after heating the sauce in a microwave.
  • the present tray and combination product provides benefit for certain of the elderly or other people for whom matching of food components can be challenging, or who find such a combination to be highly convenient.
  • the tray of the present invention particularly finds benefit in the embodiment where the product is stored in the freezer and heated in the microwave.
  • the freezer to oven food preparation embodiment is an extremely convenient and safe product presentation.
  • the tray of the present invention is made from a rigid foam material, the tray is both stable to wide temperature ranges, and also provides an insulating effect that is beneficial to the handler of the sauce.
  • the insulating properties of the rigid foam material tend to protect the consumer from discomfort during handling of the sauce receptacle when frozen.
  • the same insulating properties tend to protect the consumer when the sauce receptacle is withdrawn from the microwave oven after heating, because the hot temperature of the sauce is insulated from the hand of the user by the rigid foam.
  • Figs. 1-3 show an embodiment of the present invention wherein tray 10 is provided with a plurality of individual receptacles 12 for holding individual portions of sauce.
  • each receptacle 12 has a recess 14 and a rim 16 at the perimeter of recess 14.
  • recess 14 is of a size sufficient to accommodate from about 10 to about 50 ml, and more preferably from about 20 to about 40 ml of sauce.
  • Each tray may comprise any number of receptacles as is determined to be suitable for packaging together with a predetermined number of comestible articles together in a unitary package.
  • each tray may comprise 2, 4, 6, 8, 9 or 10 receptacles of sauce, and more preferably 6 -10 receptacles of sauce.
  • the tray comprises a symmetrical array of receptacles.
  • Rim 16 may be in the form of a small lip or alternatively may be a broad flange. Preferably, rim 16 has a width of about 1 to about 10 mm.
  • Recess 14 accommodates individual sauce portions as further described below. Recesses are imparted to the tray, corresponding to the locations where portions of sauce are deposited. Recesses are preferably formed by a vacuum and heat process, as is well known in the foam sheet processing art.
  • tray 10 is formed from a rigid foam material.
  • a rigid foam material is any synthetic resin that has been converted into a rigid, polymeric matrix with a closed-cell or open-cell structure, and is sufficiently rigid to substantially hold its shape when filled with a sauce product under both frozen (-10 ° F.) and hot product temperature (225 ° F.) conditions.
  • Tray 10 may be formed from a single rigid foam material, or a laminated construction.
  • the laminated construction may optionally comprise a foam material, together with a rigidity augmenting scrim or with polymeric film layer.
  • the rigid foam material preferably is a closed cell foam configured to reduce or preclude migration of the sauce into the rigid foam material.
  • the foam is an open cell foam, preferably further comprising a sealing layer located between the foam material and the sauce to prevent migration of the sauce into the foam material.
  • the sealing layer may be any suitable material for providing sealing functionality, such as an impervious polymeric film that is appropriate for contact with food.
  • the foam tray material to be used in present invention has a density such that a 20 mil formable web has a density from about 250 to about 320 grams/1000 square inches, and more preferably has a density from about 270 to about 300 grams/1000 square inches.
  • Tray 10 is preferably safely microwaveable with food and freezable without becoming excessively brittle.
  • a preferred evaluation of the microwave ability of the tray is carried out by heating a sauce product in the tray in a microwave oven, and caramelizing the sauce product to the degree that the sauce product is no longer edible. If the tray does not substantially deform, and otherwise retains its structural integrity, it is considered to be microwavable by this evaluation.
  • a preferred evaluation of the brittleness of the tray upon freezing is carried out by freezing a sauce product in a tray to a temperature of -10°F., and dropping the frozen product from a height from all the three feet. If the tray does not visibly crack, it is deemed to be to pass this brittleness evaluation.
  • Particularly preferred rigid foam materials include cross-linked polypropylene, such as TiroFreeze, a foamed polypropylene sheet for frozen food packaging from TiroPak Convenience Food Systems, Bakel, the Netherlands. Examples of appropriate materials from which trays may be formed are disclosed, for example in US. Patent Nos. 6,063,504 and 6,132,539, the disclosures of which are incorporated herein by reference.
  • a particularly preferred foam material is made from crystalline polyethylene terephthalate ("CPET").
  • the tray has a low coefficient of thermal transfer, so that when the sauce is heated to a temperature for consumption, such as 180 ° F., the tray containing the sauce will not be uncomfortable to hold in the palm of the hand for time of at least 30 seconds.
  • tray 10 has a nominal thickness of about 0.2 to about 3.0 mm, and more preferably a thickness of about 0.5 to about 1.0 mm.
  • the foam material of the tray is provided in sheet form, with the contour of the receptacles imparted by a heat and vacuum mold process as is conventional in the art.
  • Line of weakness 17 provides a unitary tray that separates easily when desired by the consumer for individual use.
  • the tray of the present invention comprises lines of weakness between receptacles such that the consumer can readily separate the receptacles one from another by using only tensile force, without the need for separate manipulations such as removal of adhesive tape, flexing the package to further weaken the connection between the receptacles or other such inconvenient steps.
  • the line of weakness holds the receptacles together as a unitary tray until separation is desired.
  • the receptacles do not separate from each other under tensile forces that generally correspond to the amount of force normally imparted to a tray when being conveyed by conventional automated packaging equipment.
  • the receptacles do not separate under the forces encountered when dropping a tray of sauce from a height of three feet.
  • the line of weakness 17 may be any appropriate feature providing an ability to separate receptacles one from another when desired by the consumer.
  • Examples of preferred lines of weakness include, but are not limited to, scoring, lines of perforation and temporary fasteners such as staples.
  • Line of weakness 17 preferably is a line of perforation comprising a series of land areas 20 and gap areas 18.
  • the gap areas may be provided by a knife cut, or may be imparted by heat or laser or other suitable step to provide the gap area.
  • the line of weakness may be provided during the molding process of the tray through injection molding.
  • the receptacles of the present tray are joined together only by the material of the tray, and not with a separate attachment material such as adhesive tape.
  • a separate attachment material such as adhesive tape.
  • the line of weakness 17 comprises land areas 20 and gap areas 18 in a ratio of about 1:30 to about 1:5, and more preferably in a ratio of about 1:20 to about 1:10.
  • the land areas are arranged as a bridge between receptacles having a width of about 1-2 mm, with a gap having a width of about 15-25 mm between each land area.
  • This arrangement of land areas with broad gap areas provides an aesthetically pleasing orientation of receptacles in a tray arrangement. Additionally, this arrangement of land areas and gap areas provides secure connection of the receptacles, with an appropriate separability of the receptacles by the consumer.
  • the bridge or land area is made from the same material that the receptacles are made from. The manufacture of such trays without the use of additional attachment materials, such as adhesive tape, simplifies the manufacturing process and eliminates time and expense of qualifying the use of yet another material in the process.
  • a most preferred tray arrangement comprises rectangular receptacles having a length of about 30 to about 60 mm, a width of about 30 to about 60 mm, and are provided with 2-4, and more preferably two or three, land areas per adjoining receptacle lengths in a tray and 2-4, and more preferably two or three, land areas per adjoining receptacle widths in a tray.
  • One particularly preferred embodiment of a rectangular receptacle is a square shaped receptacle.
  • Fig. 4 is a perspective view of the embodiment of the invention as shown in fig. 1, with individual cover sheets 22 applied thereto in a manner to hermetically seal sauce portions (not shown) within recesses 14.
