Definitions

  • the invention relates to a device for opening and emptying a gable-top carton containing a beverage and comprising a top with two pointed tubes for piercing the top of the carton, the first tube thereby providing an outlet for the contents of the carton and the second tube an air intake.
  • Various beverages are marketed in a carton of the so-called gable-top type.
  • the opening of such cartons may sometimes cause troubles and a number of different devices for opening and emptying such cartons has therefore been developed.
  • Various of such devices include two conical tubes that are penetrated through the top of the carton, by the user, a tube being forced down on either side of the top sealing fin of the carton.
  • the vessel accommodates members pressing against the carton and in order to seal the carton against the tubes, annular means are arranged about the tubes, said means being either flexible or springbiassed.
  • US patent No. 4 271 983 describes a small clamping means with two conical tubes penetrating the inclined roof surfaces of the carton on either side of the top sealing fin, the means being squeezingly retained about said sealing fin.
  • the device In order to ensure a correct functioning of a device of the type concerned it is important, on one hand, that the device by its design ensures sealing between the carton and the tubes and, on the other hand, that the device when the tubes penetrate the top of the carton is precisely guided, thereby making sure that the device is positioned correctly in relation to the carton.
  • the object of the invention is to provide a device ensuring the optimum fulfilment of said conditions.
  • the top constitutes a lid pivotal about a substantially horizontal axis in a vessel receiving the entire carton, that both of the two tubes have lower, pointed edges facing the hinge of the lid and that at least one of the two tubes has a conical portion for sealed abutment on the carton at the pierced edge of the perforation.
  • the first tube has a substantially triangular cross-section with a first edge facing the hinge of the lid, said tube being bevelled to form its pointed edge in the shape of a proper tip and the dimensions of the cross- section increase in the direction away from the tip.
  • the surface of the triangular tube facing away from the first edge has a gradually increasing distance from the hinge of the lid in the direction away from the tip. This offers an extra good sealing.
  • the first edge has an increasing radius of curvature in the direction away from the tip. The risk of crack formation in the carton thus decreases, which otherwise might cause damage to the sealing.
  • the lateral faces of the first tube have at least one hole between the tip of the tube and the part of the tube which in use extends through the top of the carton. This ensures substantially complete emptying of the carton.
  • the first tube includes a lower, cylindrical portion whose side facing away from the hinge is bevelled to form said pointed edge, and an upper, conical portion including at least one longitudinal slit extending from the lower part of the conical portion and approximately on to the portion which in use penetrates the carton.
  • the two tubes are located in the vertical central plane perpendicular to the axis of the hinge in the vessel, the second tube being closest to the hinge and when the vessel is closed the two tubes point obliquely downwards and backwards towards the hinge at an angle of less than 10° in relation to vertical.
  • the underbody of the vessel is preferably designed to encompass the bottom and the sides of the carton and is preferably provided with an internally horizontal cross-section whose dimensions are a little larger, preferably about 5 mm, than the dimensions of the bottom of the carton. This ensures that the carton substantially retains its shape while being pierced.
  • Fig. 1 is a perspective view of a device according to the invention in the form of a vessel while the beverage is being poured,
  • Fig. 2 is a vertical section through the vessel in Fig. 1,
  • Fig. 3 is a vertical, longitudinal section through the first tube in Fig. 1,
  • Figs 3A to 3C are cross-sections at A-A, B-B and C-C in Fig. 3, respectively,
  • Figs 4A to 4D is a sequence of the mounting of the device.
  • Fig. 5 is a partially sectional view of the top in Fig. 1, and
  • Fig. 6 is an alternative embodiment of an outlet tube.
  • the device is a vessel or a pour jug 1 with an underbody 2 and a top 3.
  • the top 3 is by means of a hinge 4 and a spring lock 5 secured to the underbody 2.
  • the underbody is conveniently provided with a handle 6.
  • the gable-top is provided with a pouring spout 7 covered by a flap lid 8.
  • an air intake with a valve 9 is provided.
  • Fig. 2 shows a beverage carton 10 of the gabletop type accommoated in vessel 1.
  • Two pointed tubes 11 and 12 extend through the inclined roof surfaces 13 of the carton on either side of the sealing fin 14.
  • the first of the pointed tubes 11 is illustrated in detail in Fig. 3 and 3A to 3C.
  • Said tube has a substantially triangular cross-section with a first edge 15 facing the hinge 4 and an opposite side wall 25.
  • Tube 11 is bevelled to provide said pointing in the form of a proper tip 17. Due to said bevelling of tube 11 the lower edge 26 of the side wall 25 is located somewhat above the level of the tip 17.
  • the external surface of the side wall 25 has a smooth curvature on to the edge 26, thereby causing the distance from said external surface to the hinge 4 to increase gradually in the direction away from tip 17, as illustrated in Fig. 5.
  • the dimensions of the cross-section of tube 11 increase generally in the upward direction, and also the radius of curvature of the edge 15 increases.
  • tube 11 entails that the tip 17 and the downwards facing edges 28 extending from said tip cut out a triangular lobe 27 that is pressed downwards by the ed ge 26 of side wall 25.
  • the gradually curving side wall 25 will further exert a press on lobe 27 and the increasing radius of curvature of edge 15 will be responsible for establishing also at this edge an increased pressure from tube 11 towards the edge of the carton in the provided hole. Due to the relatively large radius of curvature of edge 15 in the portion of the tube which in use extends through the carton, i.e. corresponding to the section A-A in Fig. 3, shown in Fig.
  • the second of the pointed tubes 12 has a lower, cylindrical portion 16 that is bevelled to provide said pointing in the form of a lower, sharp edge 18 on the side of the tube that is closest to hinge 4.
  • the tube 12 has a conical portion 20.
  • the conical portion 20 which in the closed position of the vessel 1 extends through the inclined roof surface 13 of the carton and ensures sealing while utilizing the flexibility of the carton.
  • first tube 11 constitutes an outlet from carton 10 and the second tube 12 constitutes an air intake to the carton.
  • the outlet extends from tube 11 into the pouring spout 7.
  • a flap lid 8 is provided above the outlet and is swung up about a hinge 21, as illustrated in Fig. 1.
  • a valve 9 is mounted in the upper part of tube 12, said valve including an air channel 22 and a ball 23.
  • the ball 23 will settle on the air channel 22 and close it.
  • ball 23 rolls aside and allow substitute air to flow into carton 10 through air channel 22 and tube 12.
  • holes 24 are provided in the side walls contiguous to the side wall 25 in the vicinity of the portion of tube 11 which in use extends through the roof surface of the carton. Said portion corresponds to line A-A in Fig. 3.
  • the underbody 2 of vessel 1 encircles the bottom and the sides of carton 10, an interspace of some few millimeters being provided between the side walls of carton 10 and the internal side walls of the vessel underbody.
  • Fig. 6 illustrates an alternative embodiment of tube 11 which, however, in the shown proportions makes heavier demands on the flexibility of the carton material than the embodiment illustrated in Figs 3 and
  • Fig. 6 shows a tube 11a including a lower, cylindrical portion 30 which one the side intended to face away from the hinge 4 (Fig. 2) is bevelled to form the pointed edge 17.
  • Tube 11a further comprises an upper, conical portion 31 having slits 32 extending from the lower part of the conical portion 31 and almost to the portion 31a which in use is intended to extend through the top of the carton 10 (Fig. 2).
  • Figs 4A to 4D show the use of vessel 1. This is opened by grasping an edge 5A so as to release the spring lock, following which top 3 is tilted backwards about the hinge 4.
  • a beverage carton 10 is inserted into the underbody 2 of vessel 1 , as illus trated in Fig. 4A.
  • Top 3 is then again swung forwards, thereby causing the tube 12 to perforate at first one of the inclined roof surfaces 13, as it appears from Fig. 4B.
  • Top 3 is swung further forwards until tube 11 penetrates the second of the inclined roof surfaces 13. This appears from Fig. 4C.
  • Top 3 is finally swung fully forwards until the spring lock 5 comes into mesh.
  • the vessel now occupies the position illustrated in Figs. 4D and 2.
  • tubes 11 and 12 are directed downwards and a little backwards towards hinge 4, thereby forming a small angle in relation to vertical.
  • this is essential to ensure that the holes provided by the initial piercings in the inclined roof surfaces 13 are not extended beyond the final piercings when vessel 1 is closed as illustrated in Fig. 2, which would impede a safe sealing.
  • the tube hereinbefore primarily has been described with a triangular cross-section, it may alternatively have a circular, oval or other polygonal cross-section.
