Definitions

  • the invention relates to a bag for use with at least one wicket pin of an automatic bag filling equipment, said bag at least comprising: a first side wall of a synthetic film material having a wicket mounting part with at least one hole for mounting the bag on at least one of the at least one wicket pins of the bag filling equipment; a second side wall having an open part of an open material, which second side wall is joined to said first side wall such that the bag has an inside and an opening.
  • a rectangular bag having a mesh side wall formed from a synthetic resin fiber mesh and a film side wall formed from a synthetic resin film.
  • the side walls are joined together along their vertical extent to form side edges of the bag.
  • a bottom of the bag is formed by an extension of the film side wall, which is folded over and secured to the mesh side wall along a fold line perpendicular to the side edges.
  • the bag is closed along all of its edges except for the edge opposite to the bottom, which edge defines the opening of the bag.
  • the mesh side wall has an extension near the opening of the bag, which extension is a reinforcing strip of a synthetic resin film.
  • the reinforcing strip has holes formed therein for mounting the bag on the wicket pins of the bag filling equipment.
  • a disadvantage of this known bag is that, when used in an automatic bag filling machine, the bag is difficult to open.
  • a vacuum cup of the automatic bag filling machine has to engage on side wall of the bag, while the other side wall is held in position by a stop device.
  • the mesh side wall is unable to preserve suitable vacuum when seized by vacuum cups because of its breathing characteristics. Therefore, the vacuum cups can not engage satisfactorily on the mesh and hence the bag can not be opened reliably by the machine.
  • the invention seeks to achieve said goal by providing a bag as described above, wherein said second side wall has a film part of a film material for facilitating the opening of the bag.
  • the vacuum cups of the machine can act upon the film part of the second side wall and consequently the bag filling machine is able to open the bag reliably.
  • the film material has at least a lesser breathing capacity than the open material and preferably no breathing capacity at all, the cups will therefore provide better suction on the second side wall when engaging on the film part.
  • the use of the film in the second side wall reduces the manufacturing costs of the bag because the open material is relatively expensive and in a bag according to the invention less open material is used.
  • patent publication 2 085 365 a bag is known whose front comprises a net and whose back is for example of card board. The bag has no wicket mounting part, but it does have a flap which, however, merely serves for sealing the opening of the bag.
  • U.S. patent publication 3 554 368 a bag is known whose front comprises an elastomeric thermoplastic netting member and whose backing member is rigid. Also this bag has no wicket mounting part, but it does have a flap which, however, is merely used for sealing the opening of the bag.
  • U.S. patent publication 4 403 637 a reinforced flexible container is known comprising a mesh bag having a band of flexible material around it. The band is provided with a carrying opening. From U.S.
  • patent publication 4 988 213 an open-ended packing bag is known made from a film tube.
  • the bag has at its opening a removable film tab which is provided with two wicket perforations.
  • U.S. patent publication 5 741 076 a produce bag is known whose bottom portion is made from a net material and whose top portion is made from a sheet material. The top of one side of the bag is provided with an extended portion containing a pair of spaced holes allowing the bag to be hung.
  • German utility model 297 20 932 a bag is known whose front comprises a net and whose back is made of closed plastic material. The front has a reinforcing strip near the opening of the bag. Both the back and the reinforcing strip of the front are provided with holes for picking up the bag.
  • Fig. 1 shows an example of a rectangular bag 1 according to the invention.
  • the bag 1 comprises a first rectangular side wall 2 of a film material.
  • the example bag 1 further comprises a second rectangular side wall 3 having not only an open part 6 of an open material but also a film part 7 of a film material.
  • Various types of film material can be used in the first side wall 2 and in the second side wall 3, for a synthetic film material such as polypropylene or polyethylene, or a biological film material such as paper
  • three edges of the first side wall 2 are joined to three edges of the second side wall 3 by means of three straight seams 8.
  • the joining of the side walls 2 and 3 at the seams 8 may be done by any suitable bonding or sealing technique, such as heat, glue, sealant, or the like.
  • the three seams 8 are connected to each other to form a U shape.
  • an inside of the bag 1 is defined.
  • the bag and its side walls are of rectangular shape and that there are three seams in a U shaped fashion.
  • many options are open with respect to these aspects, such as options comprising bags with curved edges instead of rectangular bags and with one or more curved seams instead of abovementioned three straight seams.
  • the film part 7 is a strip adjacent to the opening 9 of the bag 1.
  • the first side wall 2 has a wicket mounting part 4 adjacent to the opening 9 of the bag 1.
  • the part 4 is an extension of the first side wall 2 of the bag 1 and extends beyond the opening 9.
  • the wicket mounting part 4 contains holes 5 for mounting the bag 1 on wicket pins of a bag filling equipment.
  • the open part 6 in the second side wall 3 of the bag 1 allows breathing of the bag 1 in order to preserve the shelf life of the produce or product with which the bag 1 can be filled.
  • the film part 7 in the second side wall 3 of the bag 1 allows the engagement of vacuum cups of bag filling equipment for opening the bag 1. It is observed that the open part 6 and the film part 7 are joined to each other, for example with a seam 14 along a slight overlap of the edges of open part 6 and film part 7. This may be done in accordance with the bonding or sealing techniques previously described.
  • the wicket mounting part 4 of the first side wall 2 is locally weakened by means of slits 10 provided nearby the holes 5.
  • the slits 10 extend from a free edge 15 of the wicket mounting part 4 towards the holes 5.
  • the slits 10 facilitate the tearing of the bag 1 from the wicket pins of the bag filling machine once the bag 1 is filled.
  • the slits may likewise extend from the holes 5 towards the edge, as is shown in fig. 6 with slits 10'.
  • the first side wall 2 exceeds the extent of the second side wall 3 by means of an extension 11.
  • the extension 11 is folded back along a fold line 12 over a portion of the second side wall 3, which extension 11 is secured to the second side wall 3 with a seam 8 in accordance with the bonding or sealing techniques previously described.
  • the enclosed portion of the second side wall 3 may extend to the fold line 12.
  • the enclosed portion of the second side wall 3 may also extend to an edge 11a of said extension 11, as is shown in Fig. 4 and thus not reach the fold line 12.
  • a bag according to the invention can be used in a method according to the invention for filling bags by means of an automatic bag filling apparatus.
  • such method is described as follows with reference to Fig. 5.
  • a number of bags are hung with their wicket holes on wicket pins of an automatic bag filling machine. Hanging on the wicket pins, the respective bags are each consecutively opened by means of a vacuum cup 13 and a stop device 13a of the machine.
  • Fig. 5 illustrates the way in which the vacuum cups 13 and the stop device 13a act upon the bag 1 of Fig. 1.
  • a vacuum cup 13 engages on the film part 7 of the second side wall 3 of the bag 1 and the stop device 13a engages on the first side wall 2 of the bag 1.
  • each bag 1 is kept in position by some suitable means, for instance by means of bag holder clamps. Through the opening 9 of the bag, the bag 1 is filled, for example with vegetables.
  • the bag according to the invention may be mounted on the wicket, opened and filled while on the wicket and then removed from the wicket, for example by tearing the filled bag from the wicket pins.
  • the bag After filling, the bag is transported to a bag closing unit of the machine.
  • a bag closing unit some options are for example a tape sealer, plastic clip(s) or a metal closure.
  • those embodiments of the invention in which the film part 7 in the second side wall 3 is located near the opening 9 of the bag, have additional advantages related to ease and reliability of closing and cutting off the bag, as well as to strength and elasticity of the closure-joint of the bag.
  • Another additional advantage of said embodiments is that, since the film has less thickness than the open material, a larger number of bags can be hung together on the wicket, which increases the efficiency of the bag filling method.
  • Fig. 6 shows an example of an embodiment in which the film part 7 is located at a different position in the second side wall 3 of the bag 1. That is, the film part 7 is located such that between the opening 9 and the film part 7 there is a first open part 6 1 , while between the bottom of the bag and the film part 7 there is a second open part 6 2 .
  • Such embodiment is suitable for instance for bag filling machines in which the vacuum cups 13 that are meant for engaging on the second side wall 3 of the bag 1, will seize this second side wall 3 somewhere approximately in the middle between bottom and opening of the bag 1.
  • the bag shown in Fig. 7 has more than one, in the example three fold lines 12a-12c along which the extension 11 of the film material of the first side wall 2 is folded.
  • the extension has a number of overlapping layers of film material, in the example layers 11a-11c and the extension has a harmonicalike shape.
  • the second side wall partly extends between the layers 11b and 11c.
  • open material such as a cross-laminated open fabric known in the art as Cross Laminated Airy Fabric (CLAF) from ANCI. is a suitable material.
  • CLAF Cross Laminated Airy Fabric
  • the open material may also be a knitted, woven or extruded material or net.
