Definitions

  • This invention relates generally to a food packaging, and more particularly, to a single-use food packaging for cheese portions.
  • Single-serve packaging typically provides consumers with a conveniently sized portion of packaged food.
  • the various characteristics of the portioned food will affect the type of package used.
  • the qualities of the stored food product such as shelf life, size, fragility, texture, processing, and storage requirements, among others, affect the particular of the food packaging. For example, a food product having an easily deformable shape may require protection such that the food product does not become deformed during shipping and handling.
  • a food product such as a processed or unprocessed cheese
  • a food product is formed into cheese sections and packaged separately, wrapped in foil.
  • the cheese having been formed into bricks, blocks, or wedges is wrapped in a thin, fragile, aluminum wrapper.
  • the thin aluminum wrapper may have a reinforced opening strip that may be grasped to pull back portions of the aluminum wrapper, which may then be peeled away from the cheese.
  • the aluminum wrapper can be difficult for a user to handle or remove from the cheese for a number of reasons.
  • the opening strip may become separated from the aluminum wrapper such that the remainder of the wrapper sticks to the cheese while the strip has separated from the wrapper and the cheese.
  • portions or slivers of the aluminum wrapper remain stuck to the cheese portions. These slivers can be difficult to remove from the cheese.
  • the user may struggle to remove the slivers of wrapper stuck to the cheese to finish unwrapping the cheese.
  • the thin aluminum wrapper also may not fully protect the integrity of the cheese from deformation, such as during shipping and handling. Further, the thin aluminum foil can be difficult for those with limited manual dexterity to easily manipulate even with the aid of the opening strip.
  • a frangible container for containing a food product, such as cheese, that promotes product protection and product freshness, while permitting convenient elution of the portioned food product.
  • the container includes a generally rigid base and an upstanding sidewall to form an interior having an opening opposite the base.
  • a flange extends outwardly from the sidewall to provide a continuous sealing surface for attachment of a flexible film to cover the opening and enclose the interior.
  • the frangible container has areas of weakness or score lines located in the sidewall and the flange of the base to allow the sidewalls to be broken into one or more segmented portions. Further, some of the segmented portions are hingedly attached to the base to permit the segments to pivot outwardly, away from the base, to allow increased access to the food product.
  • the frangible container thereby permits convenient elution of the food product from the container, while the rigid base promotes protection of the food product and the base in combination with the film promotes product freshness.
  • a film covering the opening of the base can be removed to expose the food product.
  • a segment of the sidewall can be separated from adjacent portions of the sidewall and pivoted outwardly relative to the base to facilitate access to the food product disposed on the base.
  • the container may be formed of plastic material such as a high density polyethylene. Depending on the materials chosen for the container, the cheese will have reduced adherence to the walls of the container. Further, the container material may have a non-stick property or may have a coating to provide a non-stick characteristic.
  • the food product may be formulated such as to cleanly separate from the walls of the container and not adhere thereto.
  • the plastic frangible containers provide stable, generally rigid packaging that protects the food product during shipping and handling. In addition, the user is easily able to manipulate the packaging to gain increased access to the food product.
  • FIG. 1 is a top perspective view of a single-use container for cheese portions
  • FIG. 2 is a bottom perspective view of the container of FIG. 1 ;
  • FIG. 3 is a bottom plan view of the container of FIG. 1 ;
  • FIG. 4 is a front elevation view of the container of FIG. 1 ;
  • FIG. 5 is a side elevation view of the container of FIG. 1 ;
  • FIG. 6 is a rear elevation view of the container of FIG. 1 ;
  • FIG. 7 is a cross section view of one of the sidewalls of the container taken along line 7-7 of FIG. 3 ;
  • FIG. 8 is a cross section view of another one of the sidewalls taken along line 8-8 of FIG. 3 ;
  • FIG. 9 is a top perspective view of the container of FIG. 1 , illustrated without a cheese portion therein, having one sidewall pivoted outwardly away from the base;
  • FIG. 10 is a top perspective view of the container of FIG. 1 , illustrated with a cheese portion therein, having two sidewalls pivoted outwardly to provide for increased access to the cheese portion.
  • FIGS. 1-9 A container for a food product is described herein and depicted in FIGS. 1-9 which provides for increased access to the food product while also promoting product protection and freshness.
  • the carton 10 has a generally rigid base 16 with a compartment 12 for containing a food product 14, such as a processed or unprocessed cheese portion, which is sealed within the compartment using a flexible film 26.
  • the generally rigid base 16 protects the food product and the flexible film 26 in combination with the base 16 promotes product freshness by enclosing the food product.
  • the base 16 is adapted to separate into one or more different segments to facilitate access to the food product, as will be described in greater detail herein.
  • an upstanding sidewall 18 extends about the periphery of the bottom of the base 16.
  • a flange 20 extends outwardly from an upper edge 22 of the sidewall 18, opposite of the bottom of the base 16, to provide a continuous sealing surface 24 for attachment of a film 26.
  • the sidewall 18 and the flange 20 have aligned areas of weakness 28 located therein to permit segments or sections of the sidewall 18 and the flange 20 to separate from other adjacent portions, thereby dividing the sidewall 18 and the flange 20 into segments 30.
  • the container 10 has hinges 32 located between the base 16 and certain segmented sections 30 to permit the segment 30 to pivot downwardly and outwardly from the bottom of the base 16 when the areas of weakness 28 are ruptured or broken, thereby facilitating access to the interior of the container 10, having the food product 14 stored therein.
  • the flange 20 includes a notch 34 directed toward the area of weakness 28 located in the flange 20 and the sidewall 18.
  • the notch 34 facilitates separation of the flange 20 and the sidewall 18 into segmented sections 30.
  • An underside 36 of the flange 20 may further include gripping surfaces 38 that allow the user to more easily manually grasp and pull the flanges 20 apart from one another, which thereby divides the sidewall 18 and the flange 20 into segmented sections 30.
  • FIG. 1 An illustrative container 10 having a compartment 12 with food product 14 disposed therein is shown in FIG. 1 .
  • the film 26 seals the food product 14 within the container 10. More particularly, the film 26 adheres to a continuous sealing surface 24 located on the flange 20. The sealing arrangement between the film 26 and the sealing surface 24 may provide for the container 10 to be hermetically sealed. Further, after the container 10 is filled, the film 26 may be adhered to the flange 20 under a vacuum to extend the shelf life of the food product 14. Gas flushing may also be used alone or in conjunction with the vacuum.
  • the frangible container 10 has areas of weakness 28 that may be torn or broken to provide additional access to the food product 14.
  • the frangible container 10 may further include a notch 34 directed toward the areas of weakness 28.
  • the notch 34 may provide a separation initiation feature and a visual indication of where to begin separating the container 10 into the segments 30.
  • the notches 34 may be any of a variety of sizes and that a single container 10 may include notches 34 of different sizes and locations, as shown in FIG. 3 .
  • the container 10 also may include gripping surfaces 38, which can be located on a side of the flange 20 opposite the sealing surface 24.
  • the gripping surfaces 38 facilitate manually grasping of the flange 20 by a user. For instance, after the film 26 has been removed, the user may grasp the gripping surfaces 28 on opposite flanges 20 and then tear or pull the flanges 20 apart, thereby permitting the flanges 20 and sidewall 18 to be separated into segmented portions 30.
  • the gripping surfaces 38 are positioned proximate to the notches 34 that direct the user to the areas of weakness 28 that can be broken to provide further access to the food product 14 in the container 10.
  • the gripping surfaces 38 may be a plurality of raised or elevated ribs 50 projecting from the flange 20. As shown in FIG. 2 , the gripping surface 38 may include two parallel raised ribs 50 and a parallel groove 54.
  • the container 10 further includes reinforcing ribs 40 located adjacent the areas of weakness 28.
  • the areas of weakness 28 comprise a score line or thinned area, such as a groove or a notch, that permit the user to more easily break or tear the frangible joints of the container 10.
  • the reinforcing ribs 40 flank the score line, groove, or notch.
  • the reinforcing ribs 40 may provide for a clean, straight break or tear of the area of weakness 28.
  • the reinforcing ribs 40 extend from the upper edge 22 of the sidewall 18 to just above a bottom edge 23. Thus, the lower portion of the reinforcing rib 40 does not interfere with the stacking of the containers 10 and may assist with stacking by engaging an inner rim or lip 48 of the compartment 12.
  • the container 10 may include a hinge 32 located between the base 16 and some of the segmented sections 30.
  • the hinge 32 may permit the segments 30 to pivot downwardly and outwardly from the base 16.
  • the hinge 32 is a groove 44 that extends along portions of the base 16 as shown in FIG. 3 .
  • the hinge 32 is located along the base 16, adjacent two segments 30 of the sidewall 18 that are relatively straight.
  • the sidewall 18 has three areas of weakness 26 and two relatively straight segments 30, which can pivot relative to the base 16 once the areas of weakness 26 have ruptured.
  • FIG. 7 is a cross section along line 7-7 shown in FIG. 3 and illustrates the groove 44 in the base 16 that provides the hinge 32.
  • the groove 44 may be positioned slightly inward from the outer edge of the base 16.
  • the base 16, the sidewalls 18, and flange 20 are configured in a wedge shape such that two sidewalls are substantially straight and equal in length and another sidewall has an arcuate shape.
  • the base 16 has a generally triangular or wedge shaped perimeter with three corners or joints.
  • the wedge shaped perimeter includes two edges that are relatively equal in length and a third edge with a curved profile.
  • the wedge shaped container 10 has three frangible joints 56 between the three sidewall portions 18 and each of the frangible joints 56 has an area of weakness 26.
  • the areas of weakness 26 are proximate the joints or corners of the container 10. The areas of weakness 26 permit the sidewalls 18 and the flange 20 to be sectioned into segments 30.
  • the container 10 may include three areas of weakness 28 and may be sectioned into three segments including two straight segments 30a and an arcuate segment 30b.
  • the base 16 may include grooves 44 adjacent the two straight segments 30a to facilitate hinged movement of the two straight segments 30a relative to the base 16.
  • the arcuate segment 30b does not have a groove 44 along the base 16 and, therefore, the movement between the arcuate or curved segment 30b of the sidewall 18 and the flange is limited relative to the base 16.
  • the user opens the food packaging by first removing the film 26 from the container 10. After removal of the film 26, the user then breaks or tears one of the areas of weakness 28 after which another area of weakness 28 may be ruptured. After rupturing two of the areas of weakness 28 in the container 10, one of the segments 30 is pivotable such that it may be pivoted outwardly from the remainder of the container 10, as illustrated in FIG. 9 . Such pivoting of the segment 30 provides increased access to the food product; however, for further access to the food product another area of weakness 28 may be ruptured to segment the sidewall 18 and the flange 20 into two additional segments 30 such that the sidewall 18 and flange 20 now comprises three segments 30 as illustrated in FIG. 10 .
  • a plurality of feet 46 may be positioned along the base 16 of the container 10.
  • the feet 46 may assist in the stacking of the containers atop one another. More particularly, the feet 46 on the bottom of one container may engage with an inner rim or lip 48 of the compartment 12 of another container 10.
  • the feet 46 extend along the outside edge of the base 16 without extending to the corners or joints of the base 16 thereby permitting the hinged movement of the segments 30 and avoiding interference of the feet 46 with one another.
  • the frangible container 10 also may include stacking ribs 42.
  • the stacking ribs 42 may be a thin rib of material located on the sidewall 18 of the container 10.
  • the stacking rib 42 begins at a slight distance away from the upper edge 22 and terminates a slight distance away from the lower edge 23 on the sidewall 18.
  • the stacking ribs 42 may be located along the sidewall 18 at a variety of locations.
  • the stacking ribs 42 and reinforcing ribs 40 permit the containers 10 to be stacked in an organized manner such as during various manufacturing processes or transportation of the containers 10. Further, the stacking ribs 42 also may provide a strengthening characteristic such that the sidewalls 18 are provided with addition rigidity.
  • the base 10, the sidewall 18, and the flange 20 may be comprised of a variety of different rigid or semi-rigid materials (referred to herein as rigid or generally rigid), such as a relatively stiff material including a high density polyethylene.
  • the base 16, the sidewall 18, and the flange 20 are comprised of plastic materials suitable for thermoforming or injection molding.
  • the material of the base 16 and sidewall 18 are such that the food product 14 will not adhere to the inner surfaces of the container 10. While some materials may exhibit the non-stick characteristic, other materials may require an additive or a surface coating to provide such a non-stick property to the surfaces.
  • the film 26 may be an aluminum foil with optional printed indicia thereon.
  • the film 26 may be a polymer film having optional characteristics of moisture resistance or gas barrier properties, such as polyethylene or nylon. It is anticipated that the film 26 may be a single layer of homogenous plastic, a multi-layered laminate, or a co-extruded plastic or resin film.
  • the film 26 has a portion that is manually graspable, such as a corner or an outer edge portion of the film 26 that is not adhered to the sealing surface 24 of the flange 20.
  • the film 26 includes a tab or extension portion that may be easily grasped by a user.
  • the manually graspable portion of the film 26 may be denoted with visual indicia such as instructions to pull or manipulate. Having a convenient, manually graspable portion can facilitate peeling of the film 26 from the container 10.
  • the food product 14 such as flowable cheese may be poured into the compartment 12 of the container 10. Since the food product 14 may be returned to a solid state for shipping and delivery, once the user opens the container 10, such as by removing the film 26 and rupturing the areas of weakness 28, the food product 14 will retain the shape of the container 10 without adhering to the inner surface of the walls of the container 10.
  • one or more of the film 26, base 16, sidewall 18, and flange 20 may also include one or more additives to their respective materials useful for packaging function, such as, antiblocking agents, slip agents, flavorants, antimicrobial agents, cheese preservatives, antioxidants, fillers, light barriers, oxygen scavengers, and antistatic agents, and the like.
  • the two straight sidewall segments 30a have been pivoted outward to permit easy access to the food product 14 and then, the sidewall segments 30a have returned to a resting position at a position about 45° from their generally vertical orientation.
  • the container 10 may be configured such that the straight sidewall segments 30a remain pushed outward and do not return upward to about 45° from their generally vertical orientation.
  • the hinge 32 located at the perimeter portions of the base 16 may be thinned such that the sidewall segment 30a may easily pivot outward more than 90° from its generally vertical position.
  • the container feet 46 may be moved inward such that the sidewall segment 30a may pivot freely without interference.
  • the feet 46 do interfere with the pivoting of sidewall segment 30a, a deformation may be created in the base 16 such that removal of the food product is facilitated. Nonetheless, if the sidewall segment 30a is permitted to easily pivot more than 90° from the vertical orientation, it is contemplated that the resting position of that segment 30a may be nearly flat with the base 16 except for the accommodation of the flange 20 as it might interfere with the surface upon which the container is placed. Thus, the bottom of the feet 46 and outer portion of the flange 20 may be aligned.
