Definitions

  • the present invention relates to a package for food products, in particular products such as molten cheese, butter, margarine and the like.
  • packages are used, generally having prismatic shape with rectangular base, comprising a single outer container, in the form of an aluminium foil or otherwise, which entirely wraps the food product and presents a bottom wall and lateral longitudinal walls of the package extending in ample upper covering flaps which, in the condition of closure of the package, are folded back onto the product with mutual superposition coinciding with the respective free extremities.
  • said ample upper covering flaps in contact with the product in correspondence with the head and tail ends of said package, the lateral walls of the container also extend longitudinally beyond the ends of the product and are folded back on corresponding portions of the bottom of the container realising extreme longitudinal projections or tabs of triangular shape held assembled by a sort of annular metallic joining rivet.
  • the object of the present invention therefore is to provide a package for food products that overcomes the drawbacks present in already known packages.
  • a package having the characteristics of claim 1 in particular a package for a food product, the package being a container that wraps said product and realises a bottom wall and peripheral walls of the package; characterised in that it comprises a covering element that is associated to said container to close said package, wherein said covering element presents a peripheral profile and is integrally joined, in correspondence with at least part of its own peripheral profile, to the peripheral walls of the container and detachable therefrom; said container presenting extension portions of the peripheral walls, which extension portions of the peripheral walls, at least in the re-closure conditions of the package subsequent to the initial opening of the package itself, are able to be superimposed, by folding back, onto the covering element.
  • the present package it is thus possible to obtain, thanks to the provision of a covering element joined to and detachable - without compromising its integrity in a substantial manner - from the contamer, an easy access to the product contained therein and it is also possible, thanks to the co-operation between the projecting portions of the lateral walls of the package and said covering element, to obtain a re-closure of the package that presents a more hermetic seal with respect to known packages and allows to obtain a better preservation of the packaged product. Moreover, with the present package structure a lesser usage of material used to realise the package is obtained with respect to prior art packages.
  • FIG. 1 shows a perspective view, in a condition of integrity prior to opening, of a first preferred embodiment of the package of the present invention
  • FIG. 2 shows a cross section view of the present package with superposition flaps lifted
  • FIG. 3 shows a perspective view of the covering element alone
  • FIG. 4A, 4B, 4C, 4D, and 4E show partial views illustrating the opening and re-closure of the package according to the preferred embodiment of the present invention.
  • Figures 1 through 3 show a preferred embodiment 10 of the package of the present invention, which is used to contain a food product 11, such as butter, margarine or molten cheese, having in particular a solid and pasty consistency and which is destined to be used several times in small quantities.
  • a food product 11 such as butter, margarine or molten cheese
  • the present package 10 can, in principle, be conformed in any required shape, it preferably presents a prismatic shape with rectangular base and comprises an external container 12, which wraps said product 11 and defines a bottom wall 14 and peripheral walls, in particular a head wall 16 a tail wall 18 and opposed longitudinal lateral walls 20 and 22, and a covering element 24 which is advantageously associated to said container 12 to close superiorly said package 10.
  • said container 12 presents, starting from the upper edge of the peripheral walls 16, 18, 20, 22, of the flaps or portions extending the peripheral walls themselves, indicated respectively with the numerical references 26, 28, 30, 32, which extending flaps or portions 26, 28, 30, 32 are able to be superimposed in the condition of intact package (as Figure 1 shows), with downward folding, on the covering element 24 in correspondence with the peripheral edge thereof.
  • the present container 12 can be obtained preferably starting from a quadrangular planar blank (not shown in the figures) which is folded back according to transverse and longitudinal crease lines until generating the container of Figure 1.
  • Folding the blank, to obtain the prismatic container of Figure 1 produces folded back corner portions 34, 36, 38, 40, provided with respective upper extensions 34', 36', 38' and 40', which are obtained by folding back edges of the blank joining the parts thereof that realise the peripheral walls of the package.
  • the corner portions 34, 34' and 36, 36' are obtained by respective edges of the blank which extend between the opposite sides of said head peripheral wall 16 and said lateral walls 20, 22 of the container.
  • said intermediate edges are folded along a substantially median line and the two parts thereby resulting are mutually approached and folded back together on said head wall 16 realising said corner portions 34 and 36, and on the covering element 24 in correspondence with the head end realising said upper corner portions 34' and 36'.
  • corner portions 38, 38' and 40, 40' are obtained from respective edges of the blank that extend between the opposite sides of said tail peripheral wall 18 and said lateral walls 20, 22 of the container, said intermediate edges are folded along a substantially median line and the two parts that result therefrom are mutually approached and folded back together on said tail wall 18, to realise said edge portions 38 and 40, and on the covering element 24 in correspondence with the tail end to realise the upper edge portions 38' and 40'.
  • Said edge portions 34, 36, 38, 40 in folded back condition define respective edge crease lines 33, 35, 37, 39 separating said mutually adjacent lateral walls, whilst the upper parts 34' , 36', 38', 40' of the edge portions 34, 36, 38, 40 define separating crease lines 33', 35' , 37', 39' between the respectively adjacent upper superposition portions 26, 28, 30, 32.
  • said crease lines 33', 35', 37', 39' are positioned, in the assembled condition of the package, parallel and in correspondence with the upper border of the lateral walls 20, 22 of the container.
  • the covering element 14 is integrally joined, in correspondence with its own peripheral profile, to the peripheral walls 16, 18, 20, 22 of the container.
  • the peripheral union between said covering element 24 and the peripheral walls of said container 12 is obtained by the mutual welding of the peripheral border of the covering element with the peripheral walls of the container 12, in correspondence with the horizontal folding or crease lines of the upper flaps or extensions 26, 28, 30, 32 able to be folded on the covering element 24.
  • a hermetic union is obtained between the covering element 24 and the container 12 which allows a better preservation of the product in the phases prior to its initial opening and - at least in the areas wherein said union remains intact also after the first and subsequent openings - also subsequently thereto.
  • the covering element is also joined to the container in such a way as to be detachable therefrom without damaging its substantial soundness, i.e. without causing rips or lacerations in the lateral walls such as to compromise the configuration of the package itself.
  • said covering element 24 presents a rear or tail transverse border 42, longitudinal lateral borders 44, 46 and a front or head transverse border 48 wherefrom a tab portion 50 of said covering element extends longitudinally, which realises, in the way that will become more readily apparent farther on in the present description, means for gripping and pulling said cover used for opening the package.
  • said covering element presents said peripheral borders 42, 44, 46, 48 in the form of borders folded perpendicularly, preferably upwards, for a short segment, for instance for a segment indicated with reference h in Figure 2, equal to 3 mm.
  • the upper extension flaps 26, 28, 30, 32 of the container in turn present a width or height H which preferably amounts to about 10, 11 mm.
  • H preferably amounts to about 10, 11 mm.
  • the gripping tab 50 presents in correspondence with the terminal part of the tab, on its upward facing side in the intact condition of the package, means suitable to indicate said tab, so that it can be easily and rapidly identified and employed for opening.
  • Such indication means are distinguished by a different colouring 52 from that of the covering element provided in correspondence with the free te ⁇ ninal part of said tab.
  • Said gripping portion 50 is in the form of an ample portion that extends over the entire width of the border of the covering element and of the wall of the container in correspondence whereof, with the package assembled, it is positioned.
  • Said gripping tab 50 presents a quadrangular part, substantially destined to be covered by the upper projecting portion 26 of the head wall 16 of the container, which is provided with lateral borders 51 and 53 (shown in Figure 3 and in dashed line in Figure 1) which in the assembled condition of the package, as Figure 1 shows, are positioned in correspondence with and substantially parallel to the corner lines 33' and 35' separating said upper superposition portion 26 from the blended upper adjacent portions 30 and 32.
  • This disposition advantageously allows (as subsequent Figure 4C clearly shows), by acting on said gripping portion 50, to cut said upper corner lines 33' and 35' and separate the upper portion 26 of said head wall 16 from the joined upper adjacent portions 30 and 32 of the longitudinal walls 20, 22.
  • said tab 50 presents, in extension from said quadrangular part, a part with generally triangular shape having converging lateral borders 55, 57 connecting the free front edge of the tab with said lateral peripheral ripping borders 51 and 53.
  • the peripheral welding line of said covering element 24 to the container 12 therefore defines a preferential breakage area able to allow the openmg of the package and access to the product.
  • a first preferential breakage line is constituted by the junction line between the forward head edge 48 of the cover and the folding line of said head wall 16 of said container.
  • Two more preferential breakage lines are realised by the longitudinal junction lines between the lateral edges 44 and 46 of the covering element 24 and the folding lines of said longitudinal lateral walls 20, 22 of the container 12.
  • Figure 4A shows the condition in an as yet intact condition, wherein said tab 50 is folded back on said covering element 24 with partial superposition, on the tab 50 itself, of the upper flap 26 of the head wall 16 of the package and projection, from this folded back portion 26 of the container, of the part 52 of tab provided with the indication colouring.
  • all other superposing upper flaps 28, 30, 32 are folded back downwards superposing to the covering element 24 in correspondence with peripheral areas thereof.
  • To open the package as shown in Figure 4B, it is thus necessary to lift first said superposing flap 26, then said tab 50 and finally said longitudinal superposing flaps 30, 32 (as shown by arrows S in Figure 4B), possibly together with the tail flap 28.
  • the cover 24 is lowered again on the product 11 (as shown by arrow C in Figure 4E) with said tab 50 which, as shown in Figure 4E, is folded forward, at least for the first times when the package is used, beyond the transverse ripping line 16' (shown in Figure 4D) on the head wall 16, realising a protecting element for said product 11, and the upper flaps 30 and 32 of the lateral walls 20, 22 of the container 12 are then folded downward, as shown by arrows B in Figure 4E, to secure the covering element 24 to the package in the areas wherein it has been detached from the container 12.
  • the head wall 16 and the forward parts of the longitudinal walls 20, 22, together with the front part having the tab 50 of the covering element 24, are progressively crumpled on the product protecting and preserving the part of product remaining inside the package.
  • the present covering element 24 may remain always integrally connected to the container, at least in correspondence with the tail border 42, for the entire time during which the package is used, with the advantage that no problems are encountered with the repositioning of the cover 24 at the time of re-closure and that the latter can therefore be effected even more easily.
  • Said container 12 and said covering element 24 are both realised starting from a sheet, destined for food packaging uses, of plastically deformable aluminium.
  • the junction welding between the covering element 24 and the container 12 is obtained by providing at least on the mutually engaging parts a welding shellac which can be activated by heating. It is however preferred to apply the welding shellac on the entire lower surface of the coating element, with the exception of the area 52 of the free end of the grip tab 50, and on the entire inner surface of the container 12.
  • a welding shellac which can be activated by heating. It is however preferred to apply the welding shellac on the entire lower surface of the coating element, with the exception of the area 52 of the free end of the grip tab 50, and on the entire inner surface of the container 12.
