Definitions

  • the present invention concerns a cardboard packaging of the carton type, especially for ice-cream, and of the kind where outwardly and upwardly sloping side parts at the bottom corners create angles which are greater than orthogonal angles.
  • This shape can easily be achieved by using carton sides which are so trapezoidal that when in their raised state they will slope outwards upwardly, in that the corner edges themselves will also be outwardly and upwardly sloping, and even more outwardly sloping than the adjacent wall parts.
  • the shape offers the advantage that material like ice-cream which can be desired to be "dug up" from the packaging, e.g. with a spoon, is easier to remove than from a purely right-angled carton, partly because there is clearance upwards and partly because it is easier to reach into the bottom corners.
  • the invention is based on the observation that the aforementioned advantage from the point of view of use is associated to a special extent precisely with the increased angle at the bottom corners, i.e. to a higher degree than to the fact that an obtuse angle is provided longitudinally with the sides.
  • the packaging in general appears with regular right-angled shape, merely with the modification that at the bottom corners there is arranged a triangular part which, from a sloping corner cut-off line at each corner of the carton's bottom field, extends obliquely upwards and outwards for angular coverage of the respective geometric corners.
  • the said corner coverage is arranged internally in a box-shaped packaging or as an externally-visible oblique triangular forming of the carton's lower corner portions.
  • the cardboard or pasteboard blank from which the carton is raised at the corners of the bottom field can be configured with obliquely projecting triangular corner flaps which, when the carton is raised, are joined with corresponding obliquely cut-off end edges on the carton's side fields, so that these fields can be raised to the vertical but, however, with connection to oblique corner flaps, which seen from both the outside and the inside provide both an oblique as well as upwardly narrowing cutting-off of the bottom corner.
  • this can be achieved in a simple manner by using a carton material which is blanked out with the relevant, special triangular corner fields extending obliquely from the corners of the bottom field.
  • the outwardly sloping triangular corners are provided only over a lower extent of the carton's height, while above this the side of the carton has a normal right-angled shape.
  • This configuration can also be preferred from another aspect, namely in cases where the carton is desired to be configured with a re-closable cover of the flap type, i.e. where an upper cover field, which extends from a fold-line along the upper edge of the side-wall fields, has projecting cover-skirt fields along its free front edge and opposing end or side-edges.
  • corner fields on such a cover-skirt can for good reason not be configured for abutment against carton corner fields which extend obliquely upwards and outwards, the reason being that the cover could thus neither be closed nor opened, and if the cover-skirt is provided with right-angled corners extending downwards over downwardly-inwardly sloping carton corners, the skirt corners will stand out from the carton corner edges, which potentially entails problems regarding damage in the handling of the cartons.
  • the extent of the height chosen for the triangular corner fields is such that these just reach up to the lower ends of the cover-skirt corners, a harmonically compact overall surface is achieved, completely without any inconvenient projections.
  • the carton blank shown in Fig. 1 has a bottom field 6 which at oblique corner lines 30 has obliquely extending corner parts consisting of triangular outwardly-pointed corner fields 2 with corner flaps 4, and which has side walls consisting of side pieces 8, front piece 10 and back piece 12, all of which have obliquely cut-off side edges along lines 28, so that the breadth of the side walls is smallest along the bottom field 6.
  • the carton blank also comprises a cover field 14 which extends from the back piece 12 along a cover fold-line 40 and has cover skirt parts consisting of cover side pieces 24 with parts 26 which can be torn off, plus a cover front piece 16 which has an extension, partly with a strip 18 which can be torn off and partly a sealing part 20.
  • the cover front piece also has cover corner flaps 22.
  • the corner flaps 4 are bent so that their planes form a right-angle, while at the same time the corner fields 2 are turned up from the bottom field 6 at such an angle that the corner flaps are in planes which are at right-angles to the bottom field. It is hereby possible to fasten the side pieces 8, the front piece 10 and the back piece 12 to the corner flaps 4 in the formation of vertical walls, so that the side edges of the walls are along the sides on the triangular upwardly-pointed corner fields 2, which is illustrated by the sketches Figs. 4 and 5.
  • the figures also show the flap cover formed from the carton blank. This is arranged to be re-closable after having been torn open, see Fig.
  • the flap cover pivots around the cover fold line 40 and has skirt parts formed by the cover front piece 16 fastened to the cover sides 24 with cover corner flaps 22.
  • the cover skirt will lie close to the carton's vertical wall parts, i.e. the side pieces 8, the front piece 10 and the back piece 12, but not around the upwardly and outwardly-pointing corner fields 2, in that the contact will only be between the tip of the corner field 2 and the inner right-angled corners in the cover skirt.
  • the projecting lower parts of the cover skirt corners will be more exposed to deformation than the remaining parts of the carton, which in a known manner is partly compensated for by the stiffness which exists at the flap assembly in the cover skirt corner.
  • corner flaps 2 with the side pieces 8, the front piece 10, the back piece 12 and the joining of the carton's other parts surface against surface can be effected in a known manner, for example by using plastic-coated carton blanks which can be stuck together surface against surface by a short period of hot-air blowing, which is expedient since the use of the carton for the storing of ice-cream and the like necessitates plastic or corresponding covering inside the carton.
  • the carton will form a cavity with inside corners which have angles which are greater than 90 degrees respectively between the corner field 2, the bottom field 6, the side pieces 8, the front piece 10 and the back piece 12, while the angle between the three latter parts and the bottom field will be a right-angle. It is hereby achieved that it is easy to remove e.g. ice-cream from the bottom of the carton's cavity, in that the ice-cream is merely scraped to one of the corners where, due to the large angles, it will be easier to get at with a spoon.
  • the carton according to the invention Compared with the above-mentioned example of a known packaging, with the carton according to the invention there is achieved the clear advantage that with walls which are at right-angles to the bottom field, the carton functions as a rectangular packaging and is therefore easy to stack. Moreover, the space utilization is improved.
  • the triangular corner fields 2 have a reduced height dimension, in that their side flaps 4, however, are extended outwards in flap parts 4' on both sides of a central extension 32' of the fold lines 32.
  • a notch 5 is provided between the parts 4 and 4'.
  • the oblique side edges on the fields 8, 10 and 12 are shortened, so that the outermost part of these fields appears with rectangular field parts 8', 10' and 12'.
  • this carton blank is raised in quite the same manner as blanks cf. Fig. 1, whereby the said outer field parts 8', 10' and 12' will be folded up to mutual vertical abutment in the corners, in that the corners will be oblique only at the lower corner fields 2, cf. the final form of the corner pieces in Fig. 7, which will appear with a bend between the upper and the lower part.
  • the formation of this bend will require a certain deformation of the material in the transition between the two parts, i.e. between the inner ends of the notches 5, which is not directly achievable by a simple folding-up.
  • the corner pieces are first raised to the vertical, after which the side fields are raised for joining along the upper corners, and thereafter the corner pieces are pressed out by means of a suitable tool in the forced forming of said corner pieces, cf. Fig. 7.
  • the corner pieces will constitute spatially deformed parts which provide a relatively strong reinforcement, whereby the thickness of the carton can be minimized.
  • the cover skirt can hereby co-operate in a normal manner with a fully rectangular upper part of the carton, and the carton will distinguish itself only by the important fact that the lower bottom corners have been flattened out at the sacrifice of only a small part of the carton's volume.
  • the invention is not particularly related to a possibly appearing carton cover 14, but it must be mentioned, however, that it has been found to be advantageous to modify the said integrated cover, in that if this exists as an independent, simply adhered unit, it can be provided with improved reclosing characteristics corresponding to the cover closing of the so-called neck-cartons, where the swivel axis of the cover lies at a level down under the top plane of the carton, and where at its front edge area there is subsequently provided a certain resilient resistance against opening and closing of the cover, i.e. a desirable resistance against a much too easy opening of the re-closed cover.
  • FIG. 6 Such an alternative arrangement of the cover is illustrated in Fig. 6, where the cover field 14 with associated skirt fields 16 and 24, plus a further, rearmost skirt field 18, can appear as an independent element which, in towards the carton blank itself, is limited as shown by the stippled lines a.
  • the skirt field 18 is extended in an outer flap piece 19 which, outside a fold line p, is glued to the back piece 12 of the carton.
  • the skirt field 18 has projecting end flaps 21 which can be connected to and form fixed corner joints with the cover field's side flaps 24, so that the cover can appear with four skirt pieces.
  • the side field 12 of the carton is simply cut off along the line 40.
  • Figs. 10 and 11 show the cover in the closed and partly open position. Since the flap piece 19 and herewith the fold line p are disposed at a distance below the top plane of the carton, as with the so-called neck-cartons it is achieved that the front edge area offers a certain resistance against the opening of the carton, which provides an expedient reclosing capability.
