Definitions

  • the present invention relates to a method as defined in the preamble to Claim 1.
  • Spouts of this type are currently used in containers for pouring out products of various types, in granular or powder form, such as, for example, salt, sugar, cereals, detergents, etc.
  • the spouts are usually made of aluminium or plastics and are connected, by folding, to a tongue which is formed in a wall of the container by making an inverted U-shaped cut therein, and on which a central portion of the spout is fitted by folding.
  • aluminium or plastics spouts does not permit complete recycling of the spout together with the container once the container has been emptied of its contents .
  • This technique which therefore requires the provision of a system for applying the glue, in turn has a first disadvantage inherent in the costs of the installation and the control of the system for applying the glue.
  • a second disadvantage which is of a practical nature, is connected with the fact that the apparatus for applying the glue inevitably tends to leak drops of glue which are deposited at undesired points and may impede the operation of the packaging machine or of the apparatus which inserts the spouts in the boxes or, in other cases, may prevent the spout from opening because it is also glued to the fixed portion of the box.
  • the use of the gluing technique is also disadvantageous from the production point of view because it cannot easily be applied to rotary machines which insert the spouts in the boxes automatically.
  • the object of the present invention is therefore the fitting of cardboard spouts of the type specified above, overcoming the disadvantages of the prior art discussed above.
  • this object is achieved by a method comprising the steps defined in independent Claim 1.
  • a further object of the invention is to propose a type of cardboard which is suitable for making spouts that can be fitted to cardboard containers by such a method.
  • this further object is achieved by a container with a spout having the characteristics set out in independent Claim 8.
  • Figure 1 is a partial perspective view of a container having a spout in the closed position
  • Figure 2 is a partial perspective view of the container of Figure 1 with the spout in the open position;
  • Figure 3 is a partial, longitudinal, vertical section through the container with the spout in the open position
  • Figure 4 is a section taken on the line IV-IV of Figure 3 ;
  • Figure 5 is a front view of a spout in the flattened condition prior to being inserted in a container
  • Figure 6 is a partial perspective view of a container arranged for the fitting of the spout of Figure 5;
  • Figures 7 to 10 are front views of alternative embodiments of a spout according to the invention.
  • Figure 11 is a horizontal section showing the step of the insertion of a spout in a container
  • Figure 12 is a horizontal section which shows the spout fitted on the container in accordance with the invention.
  • Figure 13 is a section similar to Figure 12, showing an alternative embodiment of the present invention.
  • a spout is fitted on a box-like container 20 in order to pour out a product in granular or powder form (not shown) held in the container 20.
  • the general configuration and the operations to open and close a spout of the type shown in Figure 1 and 2 may be considered generally known. Consequently, only the elements which are of specific significance and interest for the purposes of the implementation of the present invention will therefore be described in detail in the following portion of the present description.
  • the container 20 ( Figure 6) comprises a vertical wall 21 in which a substantially inverted U-shaped cut 22 is formed to define a tongue 23 which pivots outwardly about a transverse and horizontal articulation line x to open the container.
  • the spout 10 has a central portion 10a which is the portion that is to be restrained on the tongue 23, and two lateral fins 10b, 10c which can be bent along respective bend lines 10b', 10c' along which the fins are joined to the central portion 10a.
  • Two identical protuberances lOd formed at the top, at the lateral edges of the fins 10b, 10c, have the function of stop elements for abutting the wall 21 of the container in order to define the position of maximum opening of the spout, as shown in Figure 3.
  • Both the spout 10 and the container 20 are advantageously made entirely of cardboard.
  • An important characteristic of the solution according to the invention is that the spout 10 is connected to the openable tongue 23 by folding.
  • two cuts 11, which are V-shaped in this embodiment, are formed in the central portion 10a of the spout so as to define a pair of triangular tabs 12 which are inserted in a respective pair of through-cuts 24 formed in the tongue 23.
  • the end portions of the tabs 12 are bent forcedly against the inner surface 23b of the tongue 23 ( Figure 4) .
  • the function of the tabs 12 is to keep the spout firmly restrained on the tongue 23.
  • the tabs 12 When the spout is opened by pulling its upper edge in the direction indicated by the arrow A in Figure 2, thus pivoting the tongue 23 and the spout 10, as a unit, in a substantially vertical and longitudinal plane, the tabs 12 oppose detachment of the spout from the tongue 23 since they are bent in the opposite direction to that indicated by the arrows B in Figure ; these arrows represent the direction of the pivoting which the tabs would perform if they were subjected to an excessive opening force which would straighten out the end portions of the tabs longitudinally, allowing them to slip through the cuts 24.
  • the tabs 12 may be triangular ( Figure 7) , trapezoidal ( Figure 8) , or rectangular ( Figure 9) , may be arranged in horizontally or vertically aligned or staggered pairs, and may be distributed in various ways in the central portion 10a of the spout, either in the vicinity of the central region of this portion, or in its peripheral regions. If pairs of tabs are formed, their ends may equally well be facing one another, as in the embodiments of Figures 7-9, or facing in opposite directions, as in Figure 10.
  • a thickness of between approximately 0.30 mm and approximately 0.55 mm a substance of between approximately 480 g/m 2 and approximately 625 g/m 2 , a density of between approximately 1.15 g/m 3 and approximately 1.30 g/m 3 , longitudinal and transverse stiffnesses of 450-650 g/cm and 200-300 g/cm, respectively.
  • Spouts can be fitted on cardboard containers with the use of automatic inserting machines having generally known structural and functional characteristics which do not therefore need to be described in detail herein.
  • automatic inserting machines having generally known structural and functional characteristics which do not therefore need to be described in detail herein.
  • rotary or non-rotary inserting machines, or even inserting machines of other types may equally well be used.
  • a strip of spouts connected to one another and in a flattened configuration is mounted on the inserting machine.
  • Non-rotary inserting machines are usually disposed between a store of still-closed cardboard containers and a packaging line; these machines perform a repetitive cycle in which they pick up a still-closed cardboard container from the store by means of a suction member and open the container, cut a spout from the remainder of the strip, bend it, giving it a substantially C-shaped cross-section and then insert it automatically in the container which is then removed by means of a conveyor belt .
  • Rotary inserting machines are disposed beside or astride the packaging line and have a rotary carousel on which the already-opened containers arrive; for each container, the machine separates a spout from the strip, bends it and inserts it in the container.
  • cuts 24 are formed in the vertical wall 21 of the container for receiving the tabs 12 of the spout and the inverted U-shaped cut 22 which defines the openable tongue 23 is also formed ( Figure 6) .
  • a spout 10, still in the flattened condition ( Figure 5) is cut from the strip and is bent to a C-shape, the lateral fins 10b, 10c and the tabs 12 being arranged parallel to a longitudinal vertical plane.
  • the spout is then pushed against the outer surface 23a of the tongue 23, the lateral fins 10b, 10c being fitted into the vertical portions of the cut 22 whilst the tabs 12 are inserted with force through the cuts 24 ( Figure 11) and are then bent forcedly against the inner surface 23b of the tongue 23, adopting the configuration shown in Figure 12.
  • the spout is thus firmly attached to the container; by virtue of the. resilience of the cardboard, the fins 10b, 10c are free to open out inside the container, as shown in broken outline in Figure 12, tending to keep the spout in a closure position.
  • the spout is fitted on the internal surface 23b of the tongue 23 and the tabs 12 are bent onto the outer surface 23a.
  • the inverted U- shaped cut 22 which defines the tongue 23 may be formed in two distinct steps: in a first step, the producer of the cardboard which is to form the container 20 forms two parallel cuts or punchings defining the sides of the tongue 23, whereas the upper portion of the cut 22 (which is shown curved in Figure 1) is performed subsequently by the maker- up of the package, immediately prior to or during the insertion of the spout .

Abstract

L'invention concerne un procédé consistant à former une première incision (22) dans une paroi (21) d'un récipient (20) de manière à définir une languette (23) qui peut être ouverte vers l'extérieur. On prend ensuite un élément (10) de carton découpé de manière à former un bec verseur comprenant une partie (10a) centrale qui vient se placer sur la languette (23) et deux ailettes (10b, 10c) latérales qui peuvent être pliées. On forme une seconde paire d'incisions (24) traversantes dans la languette (23) et une troisième paire d'incisions (11) dans la partie (10a) centrale, de manière à définir deux pattes (12). Les ailettes (10b, 10c) et les pattes (12) sont repliées perpendiculairement à la partie (10a) centrale, puis les ailettes (10b, 10c) sont insérées dans la première incision (22), et les pattes (12) sont insérées dans les secondes incisions (24) de la languette (23). Les extrémités libres des pattes sont repliées et poussées contre la languette (23) de sort à produire un bec relié à la languette (23) par l'intermédiaire des deux pattes repliées.
