Definitions

  • the present invention relates to a container of flexible material for liquid and doughy products and the like, and a relative method of manufacture.
  • the user must therefore detach the straw and pierce the membrane covering a hole provided in the package.
  • the object of the invention is to eliminate the aforementioned drawbacks, providing a container for liquids that is simple to make and therefore economical, practical in use, and ensures the maximum hygiene during consumption of the product.
  • the container according to the invention is of the type described in European patent No. 522 326, in the name of the same applicant, and is obtained by successive folding and welding of a sheet material in one or more layers, with two opposite frames at the top and bottom of the container, to give it stiffness.
  • Such a container is improved according to the invention by providing a spout in its top wall, connected to the corresponding reinforcing frame of said wall by means of a flexible membrane, which is folded to the inside of the container when not in use, forming a housing for the spout, which is disposed beneath the plane of the top wall of the container.
  • the upper end of the spout is anchored and sealed with a liquid-tight seal to a peelable diaphragm that covers the upper wall of the container, and is provided with a pull tab that facilitates its removal.
  • the spout is raised from its seat thanks to elastic yielding of the membrane that connects it to the frame and is turned to the outside of the container.
  • the spout can advantageously be made for the spout to be connected to the covering diaphragm by means of a bellows-type tab that extends during raising of the covering diaphragm, avoiding folding of the spout, which therefore rises more or less vertically when the diaphragm is torn upward.
  • the spout thus remains on the outside of the container, for easy gripping by the user. Discharge of the liquid can be facilitated by lightly squeezing the container with the hand.
  • the container for liquid products, particularly beverages, doughy products and the like according to the invention has been indicated as a whole by reference numeral 1 and is substantially parallelepiped in shape.
  • an upper or covering frame 3 and a lower or base frame or bottom 4 are applied, advantageously by welding, and in this case are in the form of a rectangular or square frame, depending upon the shape of the container 1 in horizontal section.
  • the container 1 has respective vertical folds 5 on the two opposite side walls (see in particular Figures 1 and 3), and a horizontal fold 6 is provided on a third side wall of the container, as shown in Figure 2.
  • the frames 3 and 4 and the folds 5 and 6 give stiffness to the container 1, which would otherwise be soft.
  • the top frame 3 is connected to a flexible membrane 10, in the center of which is applied a spout 11 for dispensing the liquid held in the container 1.
  • the free end of the spout 11 is sealed tight by a bellows-type flap 12 connected on the inside to a peelable covering diaphragm 13 that covers the top wall of the container and has a pull tab 14, such as to facilitate its removal.
  • the flexible or deformable membrane 10 is turned to the inside thereof, forming a housing 15 for the spout 11, such that the end of the latter does not protrude beyond the plane of the top frame 3.
  • Opening of the container takes place by pulling the peelable diaphragm 13 upward, gripping the pull tab 14, as shown schematically by the sequence of positions shown in Figure 2.
  • the bellows-type tab 12 as it extends, maintains the spout 11 in a substantially vertical position, causing complete raising thereof when the diaphragm is torn by pulling it upward, also causing detachment of the bellows-type tab from the spout.
  • the container 1 appears as shown in Figure 3, that is with the flexible membrane 10 turned upwards on the outside of the container and the spout 11 completely free, so as to be readily be gripped between the lips of the user for consumption of the product in the container 1.
  • This operation can be further facilitated by gently squeezing the container with a hand.
  • the liquid in the container 1 can be poured into another recipient such as a glass.
  • the spout 11 could be connected directly to the peelable diaphragm 13. However, in this case, during removal of the diaphragm 13 the spout would tend to fold toward the edge 16 of the container 1, in the direction of which the pulling force is exerted on the diaphragm 13, as shown schematically by the arrows in Figure 2.
  • the package 2 of the container, the bellows-type tab 12 and the peelable diaphragm 13 are made of flexible multi-layer sheet material, for example polyester-aluminium-polyethylene, the frames 3, 4 and the spout 11 of weldable plastic material, and the membrane 10 of a material that can easily be deformed, for example thermally, such as a mixture of polyamide and polyethylene.
  • a sheet 30 of flexible material used to make the membranes 10 is unrolled.
  • a punching station 32 able to make holes 60 on the sheet 30 for insertion of the spouts 11 is provided.
  • the punching station 32 is followed by an application station 33 for the frames 3, which are positioned on the sheet from above.
  • the station 34 is followed by a pre-heating station 35, a preheating station with initial deformation 36, in which the flexible membrane 10 begins to be formed through deformation of the sheet 30 interposed between the frame 3 and the widened base 11' of the spout 11. Deformation is completed in a deformation station 37 followed by a possible second deformation station 37', where the flexible membrane 10 takes on the final shape shown in Figures 2 and 3.
  • the sheet 30 then makes a loop 38 forming a storage unit for the frames 3 with spouts 11, at the exit of which is situated a cutting station 39, which cuts the sheet along the outside of the frames 3, which are sent, together with the corresponding spouts, into a guide channel 40, along which at least one sterilization area 41 using ultraviolet rays or hydrogen peroxide is provided.
  • the flexible material 2 serving to form the package of the container 1 is unrolled from a reel 50 and fed to a punching station 51 where rectangular or square openings are made, slightly smaller in size than those of the frames 3, so that an edge 42 of the flexible material 2 is disposed around the perimeter in the surface of the of frame 3 (see in particular Figure 3).
  • the frames 3 with the spouts 11 are fed to a station 52 immediately downstream of the punching station 51, in which they are positioned in the punched part 53 of the flexible sheet material 2 and subjected to pre-welding, for example on two sides.
  • a station 54 for complete welding of the frames 3 on said outer edge 42 of the sheet 2 then follows.
  • an application station 55 is provided for the peelable membrane, possibly prepared with the bellows-type tab 12, followed by an easy-open welding station 56.
  • the sheet 2 provided with the frames 3 and relative spouts 11, as well as with the base frames 4, application of which has not been shown in Figure 4, but which takes place in a similar way to application of the frames 3, is sent to the container forming station 1, as described in the cited European patent No. 522.326, and finally to filling.
  • forming of the containers 1 takes place around a vertical mandrel 70, where welding and folding 6 are carried out giving rise to a tube open at the two sides of the container in which the two lines of welding and folding will subsequently be made. While the tube comes off from the mandrel, welding and folding 5 is carried out at the bottom, and the tube is then cut at the pre-established height, so as to obtain containers open on one side, which are sent for filling and then closed by further welding and folding 5.
