Definitions

  • the present invention relates to a covering element of paper material, in particular for food containers or trays.
  • one or more support ribs may be used, which are generally made of thin cardboard and which are arranged over the tray so as to define a corresponding "framework" (consisting of one or more arches extending between opposite tray sides).
  • the framework acts as a support for the decorative paper and avoids the lower paper surface being in contact with the foodstuffs disposed below it.
  • packages made for this type of goods can be used for transportation or temporary exhibition of the goods on the stands intended for sale.
  • these packages in association with an element acting as a serving tray, have a covering element made of plastic and often transparent material which is suitably shaped so as to form a prismatic container inside which the goods are preserved and at all events maintained in sight.
  • covering elements are therefore of one piece construction and are suitably produced by hot moulding of plastic materials such as polycarbonate or the like; contrary to what happens when confectionery goods are to be packaged, the typical use of these items does not involve the presence of decorative elements but only performs the function of separating the foodstuffs from the surrounding atmosphere; it will be understood that the external appearance of the packages made following this known technique is quite different from that typical of the confectionery packets, in terms both of sizes and mechanical and/or aesthetic properties.
  • the technical task underlying the present invention is to devise a covering element, in particular for food containers or trays, capable of substantially obviating the mentioned drawbacks.
  • the present invention also aims at devising a covering element enabling an important material saving, and in particular capable of greatly reducing the use of decorative paper, while maintaining an unchanged aesthetic appearance for a consumer.
  • the covering element 1 essentially comprises a main body 2 made of paper material.
  • This main body 2 has an upper wall 2b and a side wall 2a emerging from the upper wall 2b.
  • the main body is of such an overall geometry that the side surface 2a and upper surface 2b in cooperation define a housing space 2c.
  • this housing space 2c has a substantially convex shape, so that it can accommodate items also of greater height than that of the tray housing them without any risk of interference.
  • the housing space 2c under operating conditions, is arranged so as to hold and cover foodstuffs.
  • the side wall 2a has a free edge 3 delimiting the housing space 2c at the bottom; this free edge practically defines a lower opening (under use conditions of the covering element 1), through which the confectionery goods or in general foodstuffs are allowed to pass at the moment of carrying out packaging (for covering them).
  • the main body intended to define the covering element is made starting from a flat sheet of thin cardboard suitably cut out, which is then drawn to define the upper wall 2a and side wall 2a.
  • the side wall 2a is turned up curl-wise upon itself so as to bring said wall to the configuration shown in Figs. 1a, 1b and 1c.
  • the paper material in excess present in the corners of the covering element will be suitably compressed and will define small ribs.
  • Figs. 1a, 1b and 1c can be defined starting from a single sheet of thin cardboard (without cuts, notches or the like) which is suitably drawn and folded.
  • the main body defining the covering element is made starting from a flat sheet of thin cardboard which is such cut out that it appears as in the example in Fig. 2a or 2b, ready to be suitably folded and fixed in position until reaching the configuration shown in Fig. 2.
  • Fig. 2a or 2b are cuts or notches 30 disposed close to the angular portions designed to define the connecting portions 3c of the covering element.
  • the side regions 31 of the connecting portions 3c are intended to overlap the corresponding side regions 32 of the flaps designed to define the side surface 2a.
  • the portions intended to define the side surfaces 2a have a predetermined number of folding lines 33 to enable stiffening of the side surfaces 2a themselves, under assembled conditions of the covering element, and also to determine further engagement surfaces between said side surfaces 2a and the connecting portions 3c.
  • the main body 2 can be deformed, so that it can be conveniently worked and subsequently handled, but in particular it must have such a deformability that it can be assimilated to, and even "taken for" a true confectionery package.
  • the intrinsic deformability of the main body 2 is in any case maintained to such a level that two opposite portions of the side wall 2a can be moved apart from each other by a length equal to at least 15% of their operating distance (i.e. the distance at which they are when no outer mechanical stress is applied thereto) without causing breakages or permanent sets in the main body 2 itself.
  • the free edge 3 has a substantially rectangular shape.
  • two first sides 3a and two second sides 3b parallel to each other and mutually opposite are present.
  • sides 3a and 3b are respectively alternated with connecting portions 3c having a rounded course.
  • the main body 2 is made of a non-transparent material; in addition, the main body 2 is such shaped that it has an external appearance recalling that of a confectionery packet or packaging. Thanks to this expedient, the covering element 1 in accordance with the present invention lends itself very well to be used in confectioners' shops as it is practically very similar, from an aesthetic point of view, to packages hand-wrapped by qualified operators (that obviously earn great approbation with consumers).
  • first sides 3a typically have a length not exceeding 500 millimetres; likewise, the second sides 3b have a length not exceeding 350 millimetres.
  • Typical values of the lengths of the first sides 3a can be in fact the following: 385, 362, 330, 297, about 245 or 198 millimetres; at the same time, the typical length values of the second sides 3b can be 295, 267, 230, 215, 197, 170, or 139 millimetres.
  • a first preferred embodiment in which the main body 2 made of thin cardboard of one piece construction defines by itself the whole covering with the desired flexibility and deformability (Figs. 1 to 5) and a second alternative embodiment (Figs. 6 to 10) in which the covering element on the contrary is made of two distinct pieces coupled together prior to use to form the covering element.
  • the first main body made of paper material use of a paper having a paper basis weight included between 250 and 1050 grams per square metre is provided; advantageously, paper having a paper basis weight in the range of between 300 grams per square metre and 800 grams per square metre is employed so as to give said main body a deformable character similar to that of a manually wrapped packet.
  • the upper wall 2b has connecting portions 2d. These connecting portions 2d physically connect the upper wall 2b to the side wall 2a and have a predetermined sequence of radii of curvature varying in a continuous or discontinuous manner (depending on the design requirements).
  • this connecting portions 2d are curved so that their concavity from the side wall 2a faces the housing space 2c.
  • the connecting portions 2d In order to reach the best compromise between capability of making the connecting portions 2d and agreeable aesthetic impact, the connecting portions 2d have a minimum radius of curvature exceeding 7 millimetres (Fig. 3).
  • sequence of radii of curvature is also determined, in accordance with the present invention, so as to obtain an appropriate abutment region through which the covering element 1 will then be associated with a tray-shaped container, following modalities to be described later on.
  • the main body 2 has an abutment surface 4 which is substantially flat and faces the opening delimited by the free edge 3; obviously, this abutment surface 4 is defined internally of the housing space 2c (see Figs. 3, 3a, 4, 5 and 9).
  • the main body 2 has a ratio between its vertical dimension and the corresponding maximum horizontal dimension that does not exceed 0.25.
  • the covering element 1 further comprises a support frame 5 which is associated with the main body 2 and is set to (at least partly) give the main body 2 a preestablished shape.
  • the support frame 5 during manufacture of the covering is associated with the inside of the main body 2 so as to keep the same typical shape of a manually-wrapped package while at the same time obtaining a high structural coherence.
  • a sheet of paper material having a lower paper basis weight than that previously mentioned can be advantageously used for the main body 2: for example, a paper basis weight of about 100 grams per square metre is particularly appropriate (obviously, in this case too, glossy paper for food packaging will be preferably used for the main body 2).
  • the support frame since the support frame must mainly perform a structural function, it will be always conveniently made of paper material, but having a stronger structure: in particular, in the present invention the support frame 5 is provided to be made of thin cardboard (frames of plastic material or other could also be made, although in this case problems of ecological type would arise).
  • the support frame 5 has one or more lightening seats 6 (shown above all in Figs. 7 and 8).
  • These lightening seats are merely defined by through cavities and are fully covered with the main body 2.
  • portions of the upper surface 2b are defined that, as they are not locally supported by the support frame 5, have a greater deformability than the corresponding portions of the same upper surface 2b that are close to the support frame 5 (or in other words directly rest thereon).
  • the presence of the lightening seats 6 enables the presence of portions of the main body 2 that can be free to wrinkle or be pleated exactly as it happens in traditional packets; in this manner an appreciable aesthetic effect is reached without necessarily renouncing the possibility of an important structural coherence.
  • the main body 2 is directly in engagement with the support frame 5 (by glueing or a coupling of similar type, for example); in addition, due to clear aesthetic reasons, the support frame 5 is contained in the housing space 2c (so that it cannot be seen from the outside under use conditions of the covering element 1).
  • the lightening seats 6 are substantially confined by a plurality of upper stiffening portions 7b formed in the support frame 5. Associated with these upper stiffening portions 7b is a side portion 7a of a substantially rectangular closed conformation (of course, this side portion 7a acts as a support for the corresponding side wall 2a of the main body).
  • side portion 7a and upper stiffening portions 7b are the main constituent elements of the support frame, that will take a conformation similar to that of a flattened dome of a polygonal base (in the accompanying figures the base polygon is clearly a rectangle, but it can be any geometric figure depending on requirements).
  • the relative arrangement of the upper stiffening portions 7b can be advantageously determined based on current requirements, so as to obtain the desired compromise between aesthetic appearance and sturdiness.
  • the presence of four upper stiffening portions 7b is provided which extend starting from a central portion of the support frame 5 along directions substantially parallel to those of the first and second sides 3a and 3b (in this manner a support structure for the main body 2 is formed that is practically identical with that obtained by use of crossed thin cardboard strips in traditional packets).
  • this configuration can be obtained using two distinct transverse bands in overlapped relationship or a single sheet of thin cardboard suitably cut.
  • Fig. 7 shows another embodiment in accordance with the present invention in which there is the presence of a plurality of upper stiffening portions 7b radially extending from the central portion of the support frame 5; in this case the overall stiffness of the covering element 1 is much higher than that of a traditional packet.
  • the sheet of paper material defining the main body 2 has at least one discontinuity line 7 that is located at least at the upper surface 2b and crosses the latter in a longitudinal direction.
  • This discontinuity line 7 mainly has aesthetic purposes if the support frame 5 is present, but can also advantageously act as a stiffening rib (or even as a handgrip, depending on its sizes), should the covering element 1 be exclusively made up of the main body 2.
  • this discontinuity line 7 is defined by a first folding of the sheet of paper material, close to which (in a particularly convenient embodiment) a second folding is disposed; this second folding is parallel to the first folding and these two folds substantially give the sheet a "Z"-shaped cross section (see Fig. 10).
  • the discontinuity line 7 can be defined by different folding lines that, depending on the circumstances, will give rise to cross-sections having a more or less complicated shape (in the form of an inverted-W or of " ⁇ " for example).
  • the support frame 5 has an abutment portion 8 (that substantially corresponds to the abutment surface 4 of the main body 2), which is designed to mechanically interfere with a tray-shaped container (to be described later) so that a food container can be defined.
  • this abutment surface 4 or 8 is substantially flat and is defined internally of the housing space 2c.
  • the covering element in accordance with the invention is also provided with hooking means 20 associated with the main body and adapted to enable a removable engagement with a food tray, as better specified in the following.
  • the hooking means 20 comprises at least one predetermined stretch of the lower edge 3 turned up curl-wise so as to allow a snap-engagement with the food tray.
  • this curl 30 can extend over the whole perimeter of the lid. It is also to be noted that this curl 30 is obtained through direct folding of the side wall 2a.
  • the hooking means 20 alternatively comprises a predetermined number of tabs 21 set to enable said snap-engagement with the food tray.
  • Said tabs can be made of one piece construction with the main body 2 (Fig. 2b) or separated therefrom to be then linked thereto (Fig. 2a).
  • Said tabs 21 representing the second embodiment of the hooking means are defined by elements of rectangular form and made of thin cardboard for example, that are inserted in the main body 2 and linked thereto.
  • these tabs 21 can be folded or engaged in such a manner that they emerge from surface 2a internally of the housing space 2c.
  • the tabs 21 themselves that are in the form of laminar elements can be linked both to the connecting portions 3c (this being the preferred embodiment) and to the side surfaces 2a.
  • a grip element (not shown) associable with the main body 2 in such a manner that the package can be carried very easily.
  • this grip element can be defined by a common cloth ribbon suitably linked to an upper central portion of the main body itself (portion 2b in Fig. 1a, for example).
  • the process for manufacturing a covering element 1 in accordance with the example shown in Fig. 2 conveniently comprises the following main steps.
  • a first flat sheet of paper material preferably thin cardboard having the appropriate paper basis weight, is set and a preestablished number of cuts 30 is formed therein by punching at the connecting portions 3c.
  • the flat sheet is folded up upon itself so that it takes a concave configuration in which the connecting portions 3c are brought to the inside of the cavity defined by the covering element in partial overlapping relationship with the corresponding adjacent side surfaces.
  • the side regions 31 and 32 of the connecting portions 3a and the side surfaces 2a respectively are in overlapped relationship with each other thereby generating contact surfaces that are used for mutual engagement.
  • the body takes a tridimensional rounded shape.
  • the portions defining the side surface 2a can be folded up upon themselves along preestablished folding lines 33.
  • a configuration of the side surface 2a of the type shown in section in Fig. 4 is obtained, i.e. where the region defining the free edge 3 consists of a double wall.
  • the further end 21b of the tabs is such positioned that it projects from portion 3c so that, under engagement conditions, it interferes with an edge 10 of a tray (see Fig. 3).
  • the second embodiment (Fig. 6-10) too can be provided with the appropriate tabs 21 or curls 30 so that hooking means 20 quite similar to those of the first embodiment can be obtained for a removable engagement with the corresponding tray.
  • this packaging essentially comprises one tray 9, disposed at the lower part and designed to receive a plurality of foodstuffs (practically acting as a support surface for said foodstuffs) and a covering element 1 having one or more of the features set out above and such arranged that it can be fitted onto the tray 9 itself.
  • the shape of the side wall 2a of the covering element 2 matches the shape of the corresponding peripheral wall 9a of tray 9; in addition the abutment surface 4 or 8 (belonging to the covering element 2) is designed to be brought into contact with an edge band 10 belonging to the peripheral wall 9a of tray 9.
  • the food container hitherto described consists of tray 9 and of the covering element 1 which are mutually disposed in such a manner that a container is defined the appearance of which is practically identical with that of a hand-wrapped confectionery package.
  • a tray having one or more of the following features is provided.
  • the tray will be associable with a food container in accordance with the present invention.
  • tray 9 it first of all comprises a substantially flat bottom wall 9b and a peripheral wall 9a connected to the latter.
  • the bottom wall 9b and peripheral wall 9a in mutual cooperation define a cavity 9c designed to house a plurality of foodstuffs; obviously, this cavity 9c having an opening facing upwardly in the normal use position of the container, helps in defining the inner volume of the food container in accordance with the present invention, together with the housing space 2c confined by the covering element 1.
  • the tray will be set to contain a predetermined number of pastries, cakes or in any case products of reduced sizes as compared with the plan extension of the container itself.
  • the peripheral wall 9a has an inner surface facing cavity 2c which is substantially concave; in other words, the inner surface of the peripheral wall 9a has an arched profile in the cross section of the bottom wall 9b (as can be viewed from Figs. 1d, 3, 4, 5, 6 and 9).
  • tray 9 seen in plan view is of substantially rectangular shape, i.e. it comprises two long straight sides 9e and two short straight sides 9f. Conveniently, these short and long sides substantially correspond to the first and second sides 3a and 3b of the covering element 1; however, the shape of this tray 9 can be that of any polygon (and therefore, consistently with what described in connection with the covering element 1, it will correspond to the shape in plan view of said covering element).
  • connecting arcs are provided that are obtained, like the straight sides 9e and 9f, by cutting out the laminar material of which tray 9 is advantageously made (generally cardboard material coated with a film for food on an upper face thereof and used to make these types of trays).
  • a plurality of stiffening ribs is provided (shown in Fig. 1a) which in their major extension direction transversal to the bottom wall 9b have an arched shape corresponding to the concavity of the peripheral wall 9a along the straight sides 9e and 9f.
  • the peripheral wall 9a comprises an edge band 10 turned up outwardly and such disposed as to define, for at least one portion but preferably completely, the contour of the opening ideally delimiting the side wall 9a.
  • the edge band 10 is adapted to delimit a base portion 11 which has a concave surface practically belonging to the same peripheral wall 9a (see Figs. 1d, 3 or 4 and 5).
  • the edge band 10 is of arched shape with a convex curvature and is disposed in the extension of the concave curvature of the base portion 11 of the peripheral wall 9a.
  • the edge band 10 extends in a manner adapted to dispose its margin 12 at the end, which margin corresponds to the cutting line of the laminar material; in accordance with the present technical teachings, this margin 12 is substantially turned downwardly in the normal use position of the container, so that it prevents possible contacts of the foodstuffs with the tray 9 portion that is not covered with the film for food.
  • the arched shape with a convex curvature of the edge band 10 therefore extends in the extension of the concave curvature of the base portion 11 through an angle adapted to orientate margin 12 downwardly.
  • this extension angle of the convexity of the edge band 10 is at least as wide as about 120°.
  • the vertical plane passing orthogonal to the bottom wall 9b and the tangent to the edge at the margin point will form an angle as wide as or wider than 120°.
  • the radius of curvature of the edge band 10 must be much smaller than that of the base portion 11 in order to obtain a sufficient stiffness and must not exceed the value of 1/4 of that of said base portion, for example.
  • tray 9 Another original feature of tray 9, if the above mentioned arched ribs are present (at the connecting arcs 9d) resides in the conformation of the ribs themselves.
  • these ribs instead of consisting of arched beads as in the known art, i.e. of narrow convex regions alternated with wider (or at most of identical width) concave portions, are defined, always on the side of the concavity defined by tray 9, by convex portions disposed side by side so as to form complementary grooves which in turn substantially have the shape of sharp corners.
  • the radii of curvature of the convex portions are greatly larger than those corresponding to the concave portions and therefore the stiffening ribs at the upper folded edge are wider and individually rounded, whereas the convex portions are of much more reduced extension and at some points of their surface they are almost sharp-edged.
  • ribs are present (3 to 6, but preferably 4) to prevent the material from breaking or avoid the presence of pleats and unaesthetic marks on the material itself.
  • edge band 10 extends along the whole periphery of the tray-shaped container, it has an external development and delimits not only the straight portions of the peripheral wall 9a, but also the convex stiffening ribs and it is disposed according to an axis of curvature that is transverse to the longitudinal axis of curvature of the convex portions themselves.
  • tray 9 actually defines a hooking portion which is set to receive the curls 30 or tabs 21 of the covering element 1 in a removable engagement, making the two components integral with each other.
  • Figs. 1a or 2 the external appearance that is wished to be obtained with the present invention is that shown in Figs. 1a or 2; the other representations, while being consistent with and in compliance with the inventive idea of the present invention, are diagrammatic views adapted to highlight some of the technical features of the invention such as the shape, some dimensional ratios of the product, abutment surfaces, etc.
  • the invention achieves important advantages.
  • the construction architecture of the present invention enables availability to the public of an item having an aesthetic appearance substantially coincident with that of traditional confectionery packets while being at the same time handleable without the difficulties encountered in making traditional packets.
  • a further advantage of the covering element in accordance with the present invention is given by the fact that it enables an important paper saving in use, because less decorative paper is employed as compared with the traditional packets where said paper is used in excess since it is also placed under the bottom of the serving tray and also defines the flaps to be folded back in the packet itself.
  • such a covering element reduces the production costs and greatly simplifies the manufacturing processes, because the required shapes are not particularly complicated and the operations for preparing the covering element are of reduced number and easy accomplishment from a technical point of view.
