Definitions
- This invention relates to a package suitable for containing food that includes essentially a hermetically sealable metal can of specific shape (providing long shelf-life storage of food contents without requiring refrigeration) combined with a non-metallic encapsulation, the package as a whole enabling the contents to be heated effectively, in a microwave oven, in the opened package, to a temperature suitable for eating.
- a commonplace metal can cannot be used safely or effectively for microwave oven heating of food contents, there being potential problems as follows:
- the metal of the can is opaque to the microwave field such that there may be inadequate heating at the interface between the metal can walls and the contents;
- the present invention addresses the above-mentioned problems by incorporating the hermetically sealable can as a component of a composite package in which the can component is enclosed in an outer electrically non-conductive capsule.
- the capsule includes a repeatedly removable and replaceable vented flexible plastics overcap that may enclose the top end of the package during storage and heating, it being removable to enable the consumer to: (i) remove an easy-open top; and
- geometrical shape parameters of the can are specified, to enable attainment of sufficiently rapid and adequately uniform temperature rise throughout the contents.
- the invention consists of a package for a food product comprising a hermetically sealable metal can, the can comprising: a side wall; a bottom end wall extending radially inwardly from a bottom end of the side wall; and a top end wall extending radially inwardly from a top end of the side wall, at least said top wall being attachable by a seam to the side wall afterthe can has been filled with the food product; the package further comprising an insulating capsule comprising a sleeve formed from a heat shrinkable non-metallic material having properties of high electrical insulation and low heat conductivity and adapted to encapsulate the side wall and at least an outer peripheral portion of the bottom end wail of the can; and wherein the metal can is characterised by being squat shape in by having a notional diameter D at least twice the effective length H and wherein the can has a shape consisting of the group selected from: cylindrical; circular tapered, that is, frusto-conical; square, cubical or rectangular cubical including
- the package further comprises a microwave transparent vented plastics overcap adapted to overlie the top seam region and at least a portion of the top end wall and which is adapted to be both manually removable from the package to enable the top end wall and replaceable preparatory to heating the package in a microwave oven.
- a microwave transparent vented plastics overcap adapted to overlie the top seam region and at least a portion of the top end wall and which is adapted to be both manually removable from the package to enable the top end wall and replaceable preparatory to heating the package in a microwave oven.
- the package further comprises a manually removable tear-out panel in said top wall.
- the notional diameter for the purpose of characterising the squat shape of the can is defined as the actual inside diameter of the sidewall.
- the effective length for the purpose of characterising the squat shape of the can component is defined as the shortest linear distance measurable from the meeting point of the bottom end wall and the sidewall and the plane of the top end wall.
- the effective length for the purpose of characterising the squat shape of the can component is defined as the shortest linear distance measurable from the meeting point of the bottom end wall and the sidewall and the plane of the top end wall.
- the can component is tapered circular (i.e. frusto-conical) in shape, the smallest diameter being situated adjacent the junction of the bottom end wall and the sidewall, that notional diameter is defined in such a case as the smallest diameter.
- the notional diameter is defined as the distance between opposite parallel sides of the square. If the square shape includes a taper (again, as with the frusto-conical shape, the smallest cross sectional area being adjacent the bottom end) the notional diameter is defined as the shortest distance between the opposite parallel faces of the sidewall.
- the notional diameter is defined as the shorter distance between either of the opposite pairs of parallel sides of the rectangular faces of the sidewall, that being the shortest distance so measurable if the can is tapered.
- tapered sidewall in this specification and the claims means having a uniform (i.e. not step-wise) variation in cross-sectional area from one end to the other, as illustrated in the accompanying Figures 4, 5 and 6; or embodying shapes of can body formed by; a straight line divergence of the side wall increasing from the bottom seal to the top seam; a curved line divergence of the side wall increasing from the bottom seal to the top seam; either of the foregoing divergences but where a minor portion of the side wall adjacent either bottom and/or top seam is not divergent
- Fig 1 is a broken cross-sectional elevation of a package according to the invention.
- Fig 2 and 3 are perspective views of alternative shapes of package according to the invention.
- Ffg 4 to 10 inclusive are schematic representations, in plan and elevation view, of various forms of metal can components of packages according to the invention, to illustrate geometrical shape characteristics within the scope of the invention.
- the package 10 comprises a metal can 12, that may have tapered shaped sidewalls 13 as illustrated or may have parallel sidewalls (as illustrated for example in Fig 2).
- a bottom end wall 14 connects to the lower (as illustrated) edge of the sidewall by being hermetically seamed together at a bottom seam 28 in the 3-piece can construction illustrated.
- the sidewall and bottom end wall connection may be seamless as in 2-piece can constructions, see, e.g. Fig 10.
- a top end wall 16 is provided that in the normal manner is joined by top seam 22 to the can sidewall after the can is filled with food contents.
- a 3-piece can construction it may be the top end wall 16 that is seamed to the sidewall by the can maker and supplied to the can filler who would in that case fill the can inverted with respect to the Fig 1 orientation, that is through the bottom end and hermetically seal the can by joining, at seam 28, the bottom end wall 14 to the sidewall 13.
- the top end 16 may be of the type provided with an easily openable panel 18 whereby the user requires no mechanical can opener to gain access to the contents; rather, by use of a ring-pull 20 or the like, the panel 18 of the top end amounting to approximately 80% of its area, can be readily opened from the top end and detached, forming an opening bounded by edge 24.
- the package further comprises an insulating capsule 26 that encapsulates substantially all the peripheral outer side wall 13.
- the capsule 26 wraps further around the bottom seam 28 or, otherwise, the bottom corner as in the case of a 2-piece can.
- the capsule need not enclose the entire bottom end 14 and adequately serves its principal function if terminated as illustrated at an edge 30. It may be conveniently applied to the can by heat shrinking and the wrap around of the edge 30 may be facilitated by heat shrinking. It may also wrap around the top seam, 22 (not shown).
- a removable vented overcap 32 made of a non-metallic material, polyethylene or polypropylene being suitable.
- the overcap has a generally planar top surface 34 and a peripheral rim 36 extending downwardly from surface 34.
- the rim 36 may terminate at its lower end with radially inwardly directed lip 38 to snap over and be retained by the top seam 22.
- one or more vent holes 40 are provided to enable gases and vapours to escape from the package while it is being heated.
- the insulating capsule 26 is preferably supplied to a food canner separately from the can, enabling more convenient filling, seaming, heat processing and, if necessary, drying the can.
- the insulating capsule 26 may then be applied to the can by any suitable means, preferably including heat shrinking if required.
- the insulating capsule may be pre-printed in the form of a label, supplied either in flat form or, otherwise, in cylindrical or other formed shape.
- a suitable material comprises polystyrene foam either alone, in the form of a flexible sheet 1 to 3 millimetres in thickness, or in combination with one or more other plastics material layers.
- a smooth non-foamed outer skin layer may be provided to facilitate improved print quality.
- the heat insulating quality of the capsule is in part provided by its foamed structure and enables the can when heated to be handled directly from the microwave oven.
- the overcap 32 would normally be applied over the top of the top seam and left in place there until the intended consumer of the contents of the package desires to heat it to a suitable temperature for consumption. Prior to the commencement of heating, the overcap would be manually detached, the easily openable panel 18 would be torn out using the ring-pull 20 and the panel would be discarded. Preferably the overcap would then be replaced and the package placed in a microwave oven to be heated.
- the overcap provides reduced spattering of food during heating and its outer peripheral edge protects the top seam against possible arcing across to the metallic interior walls of the microwave oven.
- the top should not be obscured from the microwave field such as by placing one package directly on top of another during heating.
- Foods of a very thick consistency in which the heat transfer mechanism is only by way of dielectric loss to generate the heat initially combined with conductive heat transfer from the more rapidly heating material adjacent the opening to the remainder of the contents should be subjected preferably to an interrupted heating cycle that allows for a time lag between the more rapid microwave induced heating and the relatively slower dissipation of this heat by conduction towards the cooler portions of the contents at, for example, the lower corners of the package most remote from the opening formed when panel 18 is removed.
- Fig 2 shows a form of the invention in upright perspective with a portion of the insulating capsule 26 cut away to show the can 12 including its cylindrical sidewall 13 and lower circumferential seam 28. The obscured remainder of the seam and sidewall are shown schematically as dotted lines.
- the overcap 34 is shown fitted to the package as preferably for transport, storage and during heating. "- -1-
- Fig 3 shows a further form of package according to the invention, in upright perspective schematic view, namely a rectangular in cross-section shaped package.
- the insulating capsule 26 is indicated schematically in chain outline.
- Other items illustrated correspond to the reference numbers used in Fig 1 , namely:
- Figures 4 to 10 schematically illustrate geometrical variations in the metal can component 12 of a variety of package shapes within the scope of the invention.
- the metal thickness of any can comprising a package according to the invention is to be understood as being the same as is usually provided for food - containing applications, having in mind the size of the can and its process and intended product-related requirements.
- the metal thickness of the can component, the seam specifications and internal lacquer specifications are the same as would be normally used in the food canning industry.
- the diameter (or, in the case of non-circular cross-sectional shapes, the notional diameter) as defined D is shown in the upper plan view and where possible in the lower elevation view as well.
- the effective length H as defined is shown in each elevation view.
