Definitions

  • the present'invention relates to a container consisting of side wall panels, bottom and flaps arranged at the top end of the side wall panels, for the purpose of, in a wellknown way, forming the top closing of the container, and a cover-sheet placed across the opening of the container and attached to the insides of the flaps when swung outwards in a 90 angle, by means of a continuous seal running around the opening.
  • Containers intended for packaging finely granulated or pulverized contents will have to be sufficiently tight to prevent the contents from leaking out during the transportation of the container or when subject to normal handling. It is furthermore a requirement that it should be easy to open the container in a way that admits easy access to the contents, and later on, if not the whole of the contents has been dispensed, it should be possible to re-close the container in such a way that no contents are spilled when the container is placed on its side, or, for instance, placed upside down.
  • a container of this type fulfils the above requirements as regards tightness as long as the sealing of the container remains unbroken, i.e. as long as the cover-sheet is not removed.
  • flaps left to be used for the closing of the container.
  • a closing of the container by means of flaps only, folded on top of each other and holding each other together, will, however, only prevent a completely free flow of the contents, while on the other hand leakage is not prevented if, for instance, the container is placed upside down.
  • a container in accordance with the invention which is characterized therein that the cover-sheet on at least one of the mentioned flaps is applied, by means of an approximately U-shaped, continuous seal extending across the body part of the flap, in such a way that an outwards open channel is formed between the flap and the cover-sheet through cutting cit the body of the flap as well as the cover-sheet by a cut through the legs of the U-shaped seal behind the seal section connecting the legs.
  • the channel formed when the container is opened may thus, with regard to tightness, be re-closed in a satisfactory way by folding the flaps in the familiar way inwards and over the coversheet and by lockingsame' to each other.
  • the channel between the flap and the cover-sheet will, in order to facilitate dispensing, have to be widened during dispensing and subsequently re-closed in order to prevent wastage. This widening of the discharge channel is facilitated if the flap, together with the side wall panel adjoining it, are provided with-crease lines-in a suitable way.
  • FIG. 1 shows a container sealed with a covering sheet, the top flaps of the container being in a swung out position.
  • FIG. 2 shows a detail of the opening flap of the container after its outer end has been cut ofi.
  • FIG. 3 shows an open container from which the con tents is being dispensed.
  • the container shown in FIG. 1 consists of four side wall panels 1, bottom, and four closing flaps 2, which are arranged to be locked, after being folded over the top of the container, in a folded position by means of locking arrangements 3 on two of the flaps.
  • the opening of the container is furthermore covered by a covering sheet 4, which is fixed to the inside of the flaps 2 along a closed, glued seal or welding 5 running around the opening.
  • the seal 5 has been arranged in a U-shaped arch along the whole length of the flap, in the main following its edge line. Thereby an area is formed on the inside of the U-shaped seal, where the covering sheet 4 and the flap 2' are not glued to each other.
  • the side wall panel adjoining the flap 2' is furthermore provided with converging crease lines 10, arranged for outwards creasing, which from their point of convergence at the middle point of the fiap 2 continue in a crease line 9 extending across the whole length of the flap 2.
  • the flap 2' as well as the cover-sheet applied on top of it maybe provided with a perforation 7.
  • FIG. 2 shows the flap 2' after the removal of its outer part 6 by a cut (for instance cutting or tearing along a perforation) through the body part of the flap.
  • a cut for instance cutting or tearing along a perforation
  • the channel 8 which opens outwards, is limited along the fiap 2' by the seal 5 running along either side of the channel 8.
  • FIG. 3 the container is shown with the discharge channel 8 widened during the dispensing of contents 111. Otherwise FIG. 3 is marked with the same symbols as FIG. 1.
  • Thecontainer which after filling has been sealed with the cover-sheet 4 attached by a continuous glue seal 5 running around the opening of the container, is after the sealing tight for finely granulated or pulverized contents, as for instance sugar and flour.
  • a continuous glue seal 5 running around the opening of the container
  • a fibrous tuft is formed at the corner points when eventually torn open and the flaps 2 are swung outwards in angle to the outside of the side wall panels, and this tuft has proved to form a satisfactory under-layer for the glued seal in the corner points and consequently to form a satisfactory tightening.
  • Another way of solving'this problem is to apply a tensile plastic layer, for instance polyethylene, on the inside of the side walls and the flaps, and to avoid cutting the fiaps 2, or at least the plastic layer applied on these, right down to the corner points.
  • the container which in this way has been provided with cover-sheet 4, is. then further closed by folding the flaps 2 across the opening of the container and by locking the larger flaps, shown in the figure, over the smaller flaps by means of the locking arrangements.
  • the locking arrangement 3 is undone, Whereafter the flaps are swung upwards.
  • a channel 8 is formed between the flap 2 and the cover-sheet 4, extending from the interior of the container out into the free air.
  • the flap 2 is flat the channel 8 has a very small area of discharge, wherefore in this position it is of little use as a passage through which the contents could be dispensed.
  • the channel 8 may, however, be widened in the way shown in FIG. 3.
  • the crease lines 10 which commence at the vertical edges of the side wall correlated to end flap 2' converge and meet the crease line 9 in flap 2 at its base point established by the junction of this flap with the side wall.
  • Crease line 9 extends along the flap 2 bisecting the U-shaped reentrant portion of the seal zone.
  • the three crease lines thus establish an outwardly foldable inverted Y-shaped crease pattern facilitating widening of the pouring channel 8.
  • the cover-sheet 4 on the flap which in this way is folded into V-shape, is thereby bending in the opposite direction in relation to the fiap 2, resulting in a widening of the channel 8.
  • the pressure applied against the upper part of the side wall panels of the container is relaxed, whereby the channel 8 again contracts when the flap 2 and thereby the attached side wall panel straighten out by spring action.
  • the flap 2' after the required quantity of the contents has been dispensed from the container, is again folded across the cover-sheet 4, whereby the channel is closed in a satisfactory way.
  • the other flaps 2 are also folded over the container 4, whereafter the larger flaps, by means of the locking arrangement, lock themselves as well as the smaller flaps.
  • the outer part of the flap is removed in the way previously explained, whereafter the channel formed between the cover-sheet and the fiap 2' may be widened, in the way previously described, through pressing together the upper part of the container on either side of the flap 2.
  • the cover-sheet 4 In order to make it possible in this case for the cover-sheet 4 to bend outwards the corners of the larger flaps adjacent to the flap 2 may be cut off preferably before the gluing.
  • the flap is again bent backwards over the previously fixed flaps.
  • it may also for instance be provided with a tab or anything similar, which is intended to be put into a corresponding slot made in any of the other sealed flaps.
  • the cover-sheet 4 applied, in the method of construction first described, may preferably be made of a transparent material, whereby it will be possible to inspect the contents of the container.
  • a container comprising a plurality of walls forming a hollow open ended body portion of the container, end closure flaps hingedly connected to each said wall along the openable end of the container, each said flap being substantially coextensive in width with the width of the corresponding wall of the container, a sealing sheet covering the open end of the hollow portion of the container and overlapping all of said flaps and all corner portions between said flaps when the flaps are swung outwards to lie in a ubstantially common plane, and said sheet being sealed to all of said flaps and said corner portions in a seal zone along a path around the container flaps, said seal zone including a reentrant portion on one of said flaps having an essentially U-shaped configuration such as will establish an outwardly opening pouring channel between said flap and said sealing sheet upon cutting off a part of said flap and sealing sheet along a out line extending through said U-shaped reentrant portion of said sealing zone.
