Definitions

  • trays of plastic material or aluminum foil have been used for packing ready-cooked food in so called portion packages.
  • the plastic trays are usually made of a plastic material which does not withstand heating in a highfrequency oven or on a heating plate up to about 120 C.
  • Trays of aluminum foil are electrically conductive and for this reason they cannot be used for heating in high-frequency ovens.
  • Another inconvenience of such trays is a certain difficulty to apply thereto printed text or pictures, such as for instructions and advertisement. All of these inconveniences can be avoided if the tray is made of carton material which withstands temperatures up to usual heating temperature of about 150 C. and in addition thereto can be readily provided with printed text and pictures.
  • the object of the invention is to provide a carton package of sufficient tightness, strength and stability so as to be able to be heated in an oven or on a heating plate and which is easy to open and sufficiently rigid to be used itself as a dish or plate from which food can be eaten, if desired. Further, the package should be erected from a blank which may be mechanically erected and sealed.
  • the invention embodies a carton tray which can be mechanically erected so as to form a fluid-tight tray.
  • the tray is erected from a blank which at least on one side has a fluid-tight plastic coating which is adapted to be sealed and withstands heating to about 150 C., such as polypropylene.
  • a blank which by fold lines is subdivided into a bottom panel and four wall panels which at their ends are connected to each other by corner portions which by means of fold lines are subdivided into three sectors, a central sector and two lateral sectors, extending from a common apex at the adjacent corner of the bottom panel, wherein each lateral sector is in contact with the adjacent wall of the erected tray and together with the central sector forms a corner post of triangular cross section.
  • a tray which is known per se is devised according to the invention with supplementary details in the manner indicated in the annexed claims in order to form, together with a cover, the package according to the invention.
  • FIG. 1 is a perspective view of a cover for the package according to the invention
  • FIG. 2 is a perspective view of a carton tray of the package according to the invention with part of a corner broken away
  • FIG. 3 illustrates the blank for making the tray shown in FIG. 2
  • FIG. 4 illustrates a corner portion of another blank for erecting the tray of a second embodiment of the invention, all corners of the blank being identical
  • FIG. 5 is a diagrammatic perspective view of the tray corner erected from the blank in FIG. 4 partially broken and seen from the inside of the tray
  • FIG. 6 is a diagrammatic perspective view of the corner in FIG. 5 seen obliquely from above and partially open before sealing the details of the corner
  • FIG. 7 illustrates another embodiment of the cover to be sealed to the tray in FIG. 1 or 5, respectively.
  • the covers shown in FIGS. 1 and 7 as well as the blank of the trays shown in FIGS. 3 and 4 consist of a cardboard or carton material which at least on the side facing the interior of the tray has a fluid-tight coating adapted to be sealed, which may be a plastic coating, such as polypropylene. Text and pictures may be printed on the external sides of the tray and the cover. However, normally it is preferred to have a plastic coating on both sides of the tray blank in order to enable sealing by means of the plastic coating when erecting the tray.
  • the blank shown in FIG. 3' is by fold lines subdivided into a bottom panel 10 and four wall panels 11, I2, 13, 14.
  • the ends of the wall panels merge into comer portions which by means of two fold lines 16, 17 are subdivided into a central sector 18 and two lateral sectors 19, 20;
  • the angle between the fold lines 21, 22 which define the end edges of the wall panels is less than 90 so that when erecting the tray the wall panels will be obliquely inclined toward the bottom 10.
  • This tapering shape of the tray increases the stability of the tray and facilitates emptying thereof.
  • the central sector 18 has an upper extension in the form of a connecting flap 23 adapted to be folded about a fold line 24 which defines the upper edge of the central sector. Incisions 25, 26 extend through some distances from the ends of and along the fold line 24 to provide for a special character of the tray in the manner described hereinbelow.
  • edge flaps 27, 28 which: at their ends are beveled such that they fit each other upon erection of the tray and form a frame as shown in FIG.2.
  • the corner portions 15 are folded inwardly and the edge flaps 27, 28 are turned outwardly into a plane which in the erected tray is parallel to the bottom of the tray.
  • the connecting flaps 23 are turned outwardly and downwardly over the underlying end portions of the edge flaps and are secured thereto by any suitable sealing process.
  • the result is a closed frame having strong joints at the corners. Due to the double inward folding of the corner portions such that the lateral sectors 19, 20 are disposed along the insides of the wall panels of the tray, corner posts will be formed at the corners of the tray. These corner posts are in the form of pyramids having downwardly pointing apexes.
  • the connecting flap 23 is an extension of the central sector 18 of the respective comer'post and is secured to the edge flaps by sealing. As a result, the corner post will form a stiff structure which can take considerable loads without being deformed.
  • the tray can be used without the incisions 25, 26, these incisions result in an advantage because the middle portion 29 of the central sector 18 (FIG. 2) is located between the end of the incisions in the central sector and can thus be pressed inwardly into a position in which this middle portion 29 makes a substantially right angle with the bottom of the tray which facilitates the erection of the tray in an erecting machine.
  • the incisions 25, 26 thus make possible the illustrated pressing of the central sector 18 which is effected during the erection of the tray without the necessity of additional fold lines.
  • the remaining marginal portions 30 of the central sector 18 are forced into tight contact with the lateral sectors 19, 20 and may be attached to them by sealing, if desired.
  • the cover 31 has weakening lines 32, 33 in its plastic coated underside which extend along the margins of the cover at such distances as to define marginal strips 34, 35 of substantially the same width as the edge flaps of the tray.
  • the cover is sealed to the edge flaps of the tray, such as by application of adhesive stripes which may be heated immediately before the sealing operation. Instead thereof, the sealing operation may be effected immediately after the application of the adhesive stripes and before these stripes have set.
  • the plastic coating on the underside of the cover and the plastic coating on the edge flaps will be sufficient to effect the necessary seal when pressed together and heated.
  • the weakening lines 32, 33 define two tear-off tabs 36. If one of these tabs is torn off the entire cover portion 37 between the weakening lines will be torn off whereas at least some layers of the marginal strips 34, 35 remain on the edge flaps and form an additional reinforcement thereof during the continued handling of the tray after the tray has been opened.
  • FIGS. 4 to 7 will form a package which has not cut edges facing .the interior of the closed package as in the tray in FIG. 2 where the cut edges of the incisions 25, 26 are exposed to the food product in the tray
  • the food product may contain liquids which colours the cut edges and when this is not desired for aesthetic reasons, the embodiment in FIGS. 4 to 7 is preferred.
  • This embodiment will also be more effectively sealed due to the fact that the edge flaps and the cover form a continuous sealed frame as will be understood from the cover shown in FIG. 7.
  • the bottom 10 and the wall panels connected thereto and provided with edge flaps are substantially identical with corresponding details in FIG. 3.
  • the fold lines 37, 38 defining the ends of two adjacent wall panels 39, 40 are at right angles and enclose a corner portion divided .by fold lines 41, 42 into a central sector 43 and two lateral sectors 44, 45.
  • a fold line 46 forming a hinge for a connecting flap 47 having its sides connected with the edge flaps 48, 49 through intermediate edge flap portions 50, 51, which are hingedly connected with the adjacent lateral sector along a fold line 52, which may be a slit if desired, and are foldable at their ends along fold lines 53, 54
  • each corner of the tray will have folded edges 46 and 54 which do not expose any cut edges to the interior of the tray. Furthermore, the intermediate edge flap portions 51 will contribute to the strength and sealing of the corner.
  • the cover to be sealed 0n the frame formed by the edge flaps 48, 49 and the connecting flaps 47 is shown in FIG. 7 and is generally denoted by 55.
  • One side of the cover is coated with a thermoplastic layer which is cut through along a continuous incision line 56.
  • the incision has merely a depth into the outermost layers of the carton material of the cover for reasons given below.
  • a straight incision line 57 forms a tab 58 to be used when tearing off the cover.
  • Adjacent the tab the incision line 56 is somewhat retracted to form an inner tab 60 which is located outside the effective area of the heat sealing tools.
  • the package according to the invention may also be used for food which has not to be heated.
  • the cover may be a transparent foil.
  • a package especially for food products consisting of a carton tray closed by a cover and made from a single carton blank which on the side facing the interior of the tray has a fluid-tight coating and is subdivided by fold lines into a bottom panel and four wall panels connected at their ends to each other by corner portions which by means of fold lines are subdivided into a central sector and two lateral sectors extending from a common apex at the adjacent corner of the bottom panel, characterized in that in the erected condition of the tray each lateral sector is in contact with the adjacent wall panel of the erected tray and said adjacent wall panels define an external corner of said tray and the central sector has an operative position located in front of said external corner and cooperating therewith to define a comer post of triangular cross section, the upper edges of the wall panels of the tray have extensions in the form of edge flaps which are folded outwardly and form a frame in a plane parallel to the bottom of the tray, the end portions of the edge flaps being connected to each other by a connecting flap which is formed
  • a package as claimed in claim 1 wherein the wall panels of the tray make obtuse angles with the bottom of the tray so as to form a conical tray, characterized by incisions along the ends of those fold lines by which the central sector is articulated to the appertaining connecting flap, and in that the middle portion of the central sector located between the inner ends of said incisions has been pressed toward the adjacent wall panels into a position substantially at right angles to the bottom of the tray, whereas the marginal portions of the central sector have been folded into contact with the lateral sectors.
  • a package as claimed in claim 2 characterized in that the marginal portions of the central sector are sealed to the wall panels of the tray.
  • a package as claimed in claim 1 having a cover of carton material coated with a layer of plastic material on its underside, characterized by an incision line having a depth to cut through the plastic layer and through a number of layers of the carton material, said incision line defining the major portion of the cover located inside the edge flaps and adapted to be removed by tearing up one corner of the cover from its connection with the underlying connecting flaps.
