Definitions

  • the present invention relates to a container of corrugated sheet material for foodstuffs, in particular cakes and similar confectionery products, of the type comprising a bottom wall and a side wall manufactured separately of said bottom wall, wherein said side and bottom walls are made integral with each other and adapted to form a cavity having an opening facing upwardly in the normal use condition of the container itself.
  • containers of corrugated paper material for foodstuffs are usually made of two parts, ie. a bottom wall and a side wall integral with each other at their edge regions where they are glued together. These walls form a cavity having an opening facing upwardly in the normal use condition of the container itself, which is adapted to house the dough during the baking step, and the finished product when baking is over.
  • the side wall is defined by a single portion of corrugated paper material, suitably shaped and closed to form a ring by overlapping and gluing of the end flaps in order to obtain a truncated-cone conformation, so that the container slightly flares to promote its superposition on other containers thereby forming stacked packs of reduced bulkiness.
  • the upper edge of the container is a sharp edge that may sometimes cut or penetrate and is therefore dangerous during handling of the container itself.
  • the paper material consists of coupling of two or more layers, partial separations between these layers may occur, and therefore frayed regions may appear at the upper edge of the container where emerging of the cutting and trimming lines of the different layers may cause the latter to open out.
  • the technical task underlying the present invention is to devise a container of corrugated paper material for foodstuffs capable of substantially obviating the mentioned drawbacks.
  • Another important aim of the invention is to devise a container of corrugated paper material provided with a rounded edge, which is not therefore sharp at its opening.
  • a further aim of the invention is to devise a container of corrugated paper material that, where formed of two or more layers, is not subject to possible fraying at the edge of its opening, as a result of separation between the layers themselves.
  • a still further aim of the invention is to provide a container the shape of which is adapted to enable folding and bending actions thereon, as well as greater resistance to deformations.
  • a further important aim of the invention is to make the upper edge of the food container stronger by providing it with greater structural stiffness and reducing the risks of breaking of its side wall due to tearing.
  • a container of paper material for foodstuffs, in particular cakes and similar confectionery products which is characterized in that said side wall at the opening contour has a border band overturned preferably outwardly of said cavity and delimited by an annular fold of the sheet material defining said contour of the cavity opening.
  • It comprises a bottom wall 2 and a side wall 3 separated from each other and each defined by a shaped portion of corrugated sheet material, said walls being made mutually integral by gluing at a peripheral region 2a of the former and a bent edge region 3a of the latter.
  • a first portion intended to define the bottom wall 2 is provided to be cut from a substantially flat support of corrugated paper material (as shown in Fig. 4, for example).
  • a first and widespread typology of paper containers for confectionery products involves use of a bottom wall of circular shape, as shown in Fig. 1.
  • a bottom wall of circular shape as shown in Fig. 1.
  • different container shapes adapted to the type of cake to be prepared may be provided.
  • a second flat portion which is separated from the preceding one and will be used to constitute the container side wall 3.
  • This second portion will preferably consist of a strip of sheet material to be suitably bent so that its edge region 3a will be ready for gluing to the peripheral region 2a of the bottom wall 2; this portion will then be closed to form a ring around the bottom wall.
  • the container consists of at least two separate portions (a base and a side wall). This enables a side wall 3 made up of the desired amount of material to be obtained.
  • the side wall 3 will not have material in excess, swellings, folds or corrugations in addition to those already present in the strip designed to define it and the container thus obtained will therefore be much stiffer and stronger than the paper containers made through subsequent bendings starting from a single sheet.
  • the bent edge region 3a will be defined by a plurality of tabs 11 separated by a cut 12. During the engagement step with the bottom, these tabs 11 partly overlap one another thereby avoiding deformations due to excess material at this region.
  • a weakening line 13 intended to facilitate bending of the side wall 3 is also present; therefore the side wall 3 in an assembled condition will have a portion 3a parallel to bottom 2 and a portion substantially perpendicular to the latter or at most slightly flared outwardly of cavity 4.
  • Fig. 4 Also identified in Fig. 4 is an ideal folding line 14 around which the upper edge of the side wall 3 will be overturned. This overturning operation can take place by overturning of the border band 6 either when the side wall 2 is in a flat condition (Fig. 4), or before assembling with the bottom wall 2 and also possibly simultaneously with dampening of the folding region; alternatively folding will follow assembling after dampening of the region itself.
  • the side wall 3 is closed to form a ring by overlapping and gluing of the end flaps 3b that therefore will constitute a section of greater stiffness than all the remaining part of the side wall 3 itself.
  • the side wall 3 and bottom wall 2 form a cavity 4 having an opening facing upwardly in the normal use condition of the container.
  • the side wall 3 at the contour of opening 5 has a border band 6 overturned outwardly of cavity 4 and delimited by an annular fold 7 of the paper material defining said contour of opening 5.
  • the paper material of the side wall 3 comprises at least one face crossed by corrugations 8 having a major extension direction which is not oriented vertically as in common containers.
  • corrugations 8 have an inclination to the horizontal (or bottom plane 3) of an angle a not greater than ⁇ 45°, more preferably this inclination will be in a range included between ⁇ 10° and ⁇ 15° and most preferably the major extension direction will be oriented substantially parallel to the bottom wall 2 and therefore also to the annular fold 7 delimiting the border band 6.
  • the annular fold 7 is practically executed mainly at the grooves of corrugations 8 disposed at the contour of opening 5 so that achievement of said annular fold is facilitated due to the greater flexibility offered by the paper material at said grooves.
  • the strip that will define the side wall will be suitably cut from the corrugated material so as to follow the rib course.
  • the corrugation extension in the finished product will be slightly inclined and this deviation from the horizontal will be more apparent at the region where the strip edges are jointed together on the side wall because at this point the two inclinations are in opposition to each other.
  • orientation of the paper material corrugations in a direction substantially parallel to the bottom wall not only efficiently counteracts the tendential increase in the container flaring due to expansion of the dough during baking (because it brings to formation of a plurality of stiff annular ribs), but it also enables breaking of the paper material to be avoided, which on the contrary would occur if said corrugations were disposed transversely of the bottom wall, i.e. in a substantially vertical direction in the normal use condition of the container.
  • the annular fold 7 would cross the corrugation ridges at right angles where the material elasticity is obviously to a minimum degree and therefore cracking and tearing formations are very likely to occur.
  • the corrugated paper material consists of a smooth sheet 9 adapted to come into direct contact with the foodstuff and facing the inside of cavity 4, and a corrugated sheet 10 that obviously will define the outer surface of the container.
  • the annular fold 7 forms a rounded edge covered with the smooth sheet 9.
  • both sheets 9, 10 are adapted to withstand the baking temperatures required for the different types of foods.
  • the border band 6 has an extension surface disposed parallel to the side wall 3, so that penetration of the border corrugations into the grooves present in the side wall 3 and due to the corrugations themselves is possible at least partly.
  • the invention achieves important advantages.
  • border band 6 and annular fold 7 delimiting it constitute a perimetric collar greatly stiffening the upper part of the side wall 3 and reducing to a minimum the structural discontinuity effect caused by the presence, along the annular extension of the side wall itself, of the region of greater thickness wherein the end flaps 3b overlap one another and come into engagement.
  • the container in accordance with the invention therefore does not tend to become deformed during baking of the foodstuff contained therein and said foodstuff, when cooking is over, is shaped evenly without protuberances or irregular swellings.
  • the opening contour of the container is formed of the annular fold of the paper material and is therefore of rounded conformation, without sharp edges.
  • the cutting and trimming lines of said sheets are disposed at the end of the border portion folded back outwardly and downwardly and not at the opening contour of the container; possible partial separations or fraying between the sheets therefore would stop at the annular fold delimiting said border portion and could not go on in the cavity of the container itself.
