Definitions

  • the invention relates to the hose bag equipped with the handle slot and manufactured in the packaging machine from a plastic packaging foil adjusted to re-opening.
  • Hose bags manufactured by rolling the plastic packaging foil into the hosepipe with edges connected by longitudinal weld and sealed by the cross weld at lateral sides.
  • Hose bags display handle slots located in the upper part made for handling of the bag, when dealing with it in a shop or at the side of an end user.
  • a certain disadvantage of such hose bags appears to be in arduous opening. To open the bag mostly needs some tool, which will distort a part of the hose bag or remove it. In such a case, problems start occurring if the end user tries to re-seal such a distorted hose bag, for instance, in order to prevent spilling of unconsumed contents.
  • the sealing enabling re-sealing and re-opening of the flexible bag part is formed by a both sided adhesive tape positioned in the area between the external edge of the plastic packaging foil and the opening longitudinal weld.
  • the sealing suitable for re-sealing and re-opening of the flexible bag part allows manufacturing as a zip-fastener located in between the internal edge of the plastic packaging foil and the opening longitudinal weld.
  • there is a manufactured sticker for the purpose of an alternative option leading into the flexible opening of the bag part.
  • the layout is also efficient if there is a sticker in the position opposed to the solid longitudinal weld on the plastic packaging foil in the flexible bag part, which leads into the flexible opening bag part with regard to the fact that the external edges of the sticker are reinforced by stiffening welds.
  • Amenity of the hose bag that is divided by fixed longitudinal weld into a sealed part and an opening part is a possibility to open it with comfort and ease, or alternatively sealing of the opening part of the bag regardless the need to use a tool.
  • the bag Based on the layout of the external edge of the plastic packaging foil, the bag enables to be opened by pulling the external edge of the packaging foil either downwards or upwards. It is impossible to damage the bag at its opening and the possibility of a user injury caused by the opening tool is excluded, as well.
  • the fact that the sealing of the flexible bag part re-sealing and re-opening enables the end user to open the hose bag repeatedly, select a part of the packaged goods and seal it over again.
  • Zip fasteners are suitable for powder articles, both sided adhesive foil for fine piece goods producing no powder.
  • the handle slot in the sealed part of the bag makes a comfortable manipulation with the bag, trouble free both at the distribution and the end user's manipulation, as well.
  • the sticker positioned in the flexible opening of the bag part makes the bag stationary. Vertical hose packaging machines are applied to package into hose bags, whereas the hosepipe winds up around the vertical tube or a horizontal packaging machine wrapping articles into the horizontally folded strap of the plastic packaging foil.
  • the bag with the handle slot 6 that enables gripping, is produced from a continuous band of packaging foil 1 joined by heat.
  • Packaging foil 1 is shaped by a known method in the packaging machine into the hosepipe 13, and it forms the bag (Fig. 1 and Fig. 2).
  • the bag is sealed on both side sections by a set of two transverse welds 14 .
  • a fixed weld is manufactured 4 on the bag outside of the space of the overlapping edges 8.1 and 8.2 of the packaging foil 1 .
  • the fixed weld 4 splits the bag into a sealed part 2 and opening part 3 .
  • the sealed part of the bag 2 manufactured by a fixed longitudinal weld 4 and situated above the fixed longitudinal weld 4 , formed the opening 6 to enable some manipulation.
  • the flexible part of the bag 3 located bellow fixed longitudinal weld 4 is a packaged article not depicted in figures.
  • the flexible part of the bag 3 is sealed lengthwise, both by the fixed longitudinal weld 4 and by overlapping edges of the packaging foil 1 , whitch are mutually joined by the opening longitudinal weld 5 .
  • Transverse welds 14 reinforce the bag vertically.
  • the lock suitable for repeated sealing and opening of the flexible bag part 3 is formed, e.g. by a both sided adhesive tape 7.1 or a zip fastener 7.2 .
  • the lock can be positioned either between opening longitudinal weld 5 and external edge 8.1 of the packaging foil 1 (Fig. 3, fig. 4, fig. 9, fig. 10, fig. 15, fig. 16), or between opening longitudinal weld 5 and internal edge 8.2 of the packaging foil 1 (Fig. 5, fig. 6, fig. 11, fig. 12, fig. 17, fig. 18).
  • Overlap of the external edge 8.1 and internal edge 8.2 of the packaging foil 1 is structured in such a way to enable to view the standing bag and its external edge 8.1 of the packaging foil 1 leading downwards (Fig. 2, fig. 4, fig. 6, fig. 8, fig. 10, fig. 12, fig. 14, fig. 16, fig. 18). Concerning some alternative layout (fig. 19), the external edge 8.1 of the packaging foil 1 would be leading upwards. Based on suggested needs of the end user, the bottom of the flexible bag part 3 , is manufactured in a great variety of designs. Hose bags not requesting to hold a stationary position prior to their opening or upon their sealing (Fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig.
  • Bags with handle slots 6, not suggested to repeated opening and sealing during taking out packaged goods several times upon each other are equipped with fixed weld 4 and flexible opening weld 5.
  • Fixed weld 4 which separates sealed part 2 of the bag from the opening part 3 of the bag, assures that the sealed part of the bag 2 having the handle slot 6 holds intact.
  • the purpose of the opening weld 5 is to provide a lump-sum initial opening of the open-able part 3 of the bag.
  • the bag Upon opening of the flexible weld 5, the bag keeps open and closes only by flopping the external edge 8.1 of the packaging foil 1 over. Bags with a handle slot 6 enabling the grip, which are required to be opened and sealed several times after their first opening, are equipped with the lock for re-sealing and re-opening of the flexible part 3 of the bag.
  • the lock defined for repeated sealing and opening is manufactured from both sided adhesive tape 7.1 , then by pulling the external edge 8.1 of the packaging foil 1, first will be separated the flexible opening weld 5 and simultaneously parts of transverse welds 14 from external edge 8.1 reaching up to the fixed weld 4.
  • the cover strip is removed from the adhesive tape 7.1 and thus, the adhesive layer 7.1 becomes bare.
  • the way how to perform the re-sealing and re-opening of the flexible opening part 3 of the bag is done by separating and sticking of both sided adhesive tape 7.1 and internal side of the packaging foil 1 within the space determined by external edge 8.1 of the packaging foil 1 and the flexible opening weld 5 .
  • the lock enabling re-sealing and re-opening is manufactured from the zip fastener 7.2 , then by pulling first the external edge 8.1 of the packaging foil 1 opens the opening weld 5 as well as parts of transverse welds 14 will be separated from external edge 8.1 of the packaging foil 1 reaching up to the zip fastener 7.2 .
  • the zip fastener 7.2 opens. Re-sealing and re-opening of the flexible opening part 3 of the bag is done only by opening and sealing of the zip fastener 7.2 .
  • hose bag having the flexible opening and the handle slot enabling gripping, allows application in packaging of various kinds of piece as well as powder articles, such as feeding of domestic animals, frozen vegetables, washing powders, etc.
