Definitions

  • This invention relates to sealed cartons, especially for frozen foods, and is, more specifically, concerned with cartons of the type made of an integral bla-nk folded up to constitute a box-shaped bowl for receiving goods, and a hinged lid folded down and sealed against the mouth of such bowl or box.
  • Cartons of this type when used for frozen foods, should be completely liquid-tight in order to prevent leakage of water or other liquid therefrom when the frozen products are thawed.
  • a primary object of my invention is, therefore, to provide a carton of the type referred to which can be easily and rapidly sealed in a liquid-tight manner.
  • Another object is to provide a carton of the type referred to, in which an effective liquid seal is provided at the corners of the lid of the carton, when closed.
  • Another object is to provide a carton in which all such joints which might otherwise constitute an escape for liquid, are caused to end blindly when the lid is sealed to the body of the carton.
  • a further object is to provide a blank adapted to be folded and sealed to constitute a liquid-tight carton.
  • Still another object is to provide a new and useful method of sealing cartons of the type referred to.
  • FIG. 1 is a view of a blank for a carton in accordance with this invention
  • FIG. 2 is a perspective view of the carton a-fter foldingup of its box-shaped portion, the lid being, however, open,
  • FIG. 3 is a perspective view of the closed and sealed carton, certain parts being broken away,
  • FIG. 4 is a perspective view of a carton with strips of adhesive film applied thereto, before bending down of the flaps of the lid, and
  • FIG. 5 is a sectional view of one wall of the carton and adjacent portions thereof.
  • the blank shown in FIG. 1 is preferably made of cardboard coated with a thermo-sealing plastic, such as polyethylene, and is by means of folding lines divided into a bottom portion 1, a lid portion 2, and rectangular panels 3-7, of which the panel 5 constitutes one wall of the carton and is situated between the bottom portion 1 and the lid portion 2 so as to unite them with each other.
  • the other walls are constituted by the panels 3 and 4.
  • Square corner areas 8 and 9 which are integral with the wall panels 3, 4 and 5 are situated between the lateral edges thereof and are provided with diagonally extending folding lines 10.
  • the wall panels 3-5 and the corner areas 8 and 9 constitute an integral strip around the bottom portion 1.
  • hinged strips or flaps 11 and 12 Extending along the free edges of the walls 3 and 4 and integral therewith are hinged strips or flaps 11 and 12, respectively, of which at least the strips 12 are extended along the corresponding free edges of the adjacent corner areas 8 and 9.
  • the strip 11 is similarly extended.
  • the flaps 6 and 7 of the lid 2 are separated from each other through angular corner recesses 13 and from the corner areas 9 through linear incisions or slots.
  • wall panels 3-5 are folded up to the position shown in FIG. 2, the corner areas 8 and 9 being at the "ice same time folded and glued or heat-sealed to the inside of walls 3 and 5, respectively.
  • the portions 12a of the strips 12 which, through this operation, are caused to lie fiat against the inside of the lid 2, are glued or heat-sealed to the latter.
  • the carton may now be filled with goods and closed, the lid 2 being folded down onto the box-like portion of the carton and the strips 11 and 12- turned in over the same, as shown in FIG. 3.
  • the lid 2' is glued or heat-sealed to these strips 11 and 12, whereas the lid flaps 6 and 7 are glued or heat-sealed to the walls 3 and 4, whereby a liquidtight, sealed carton is provided.
  • the body of the carton constituted by the bottom 1, walls 3, 4 and 5, and folded corner areas 8 and 9, is integral and liquid-tight so that, when the lid is closed, any escape of liquid can only take place through the joints or seams between the lid and the body of the carton.
  • sealing of these joints or seams constitutes no serious problem, the lid being glued or welded to the inturned flaps 11 and 12, whereas in cartons known heretofore, difficulties will arise at the corners of the lid where capillary openings will be formed at the points indicated by arrows a in FIG. 3.
  • capillary openings are barred by the strips or flaps 12 extending integrally around the corners of the carton.
  • capillary channels may be formed at the places indicated by arrows b when the lid is glued or heat-sealed to the strips 11 and 12.
  • the lateral flaps 6 of the lid are provided, whereby the channels will end blindly at the inside of the flaps 6 when the latter are glued or heat-sealed to the walls 4.
  • FIGURES 4 and 5 A preferred closing operation for the carton of this invention is illustrated in FIGURES 4 and 5.
  • 21 is the bottom of the carton, and 22 and 23 the walls and the lid thereof, respectively, the lid being hingedly connected with one wall.
  • the free edges of the lid are provided with flaps 24 intended to be folded down along the walls 22 and cemented thereto.
  • Each wall has a strip-shaped flap 25 at its upper edge for folding into the carton, as hereinbefore described.
  • the lid 23 In closing the carton, the lid 23 is folded down to engage the inturned flaps 25 of the walls, whereas the marginal flaps 24 of the lid are folded up, as shown in the drawings, to extend in alignment with the corresponding walls 22.
  • This operation may be effected mechanically and automatically by means of suitable machinery constituting no part of the present invention.
  • a continuous adhesive film or coating 26 is applied in a narrow zone extending on both sides of the joint between the walls 22 and the flaps 24.
  • the adhesive film may consist of polyethylene, for example, and may be applied either in liquid form or in the form of an adhesive tape having adhesive properties on both sides. The application may be effected by causing the carton to move, in the condition illustrated in FIG.
  • the glue coating roller or the tape roll may be moved along the sides of the carton.
  • another strip of adhesive film 27 is applied in similar manner to the walls 22 adjacent the lower edges thereof.
  • the flaps 24 are folded down along the walls 22, as indicated through arrows A, and sealed thereto, heat being applied, if necessary.
  • a liquid-tight carton comprising a bottom, walls integral therewith and folded up therefrom, folded-in corner areas between adjacent walls and integral therewith, a lid hingedly connected with the upper edge of one wall and integral therewith, inturned flaps extending along the upper edges of the other walls and sealed to the lower side of said lid, said flaps being, on the walls adjacent that connected with said lid, extended along the upper edges of said folded-in corner areas and integral therewith, said lid being provided at its edges with flaps folded down the outer side of said Walls and sealed thereto by a continuous sealing strip at the joint between said lid flaps and the upper edges of said walls.
  • a liquid-tight carton comprising a quadrangular bottom, a front wall, a rear wall and a pair of lateral walls integral with said bottom and folded up therefrom, foldedin corner areas between adjacent walls and integral therewith, a lid hingedly connected with the upper edge of said rear wall, in turned flaps extending along the upper edges of said front and lateral walls and sealed to the lower side of said lid, the flaps of said lateral walls being extended along the upper edges of adjacent folded-in corner areas and integral therewith, said lid being provided at its lateral edges with flaps folded down the outer sides of said lateral walls and sealed thereto by a continuous sealing strip at the joint between said lid flaps and the upper edges of said walls.
