Definitions

  • the invention relates to a reclosable packaging bag made of a flexible material, which has an opening at the top.
  • Resealable packaging bags are known in many different designs.
  • the majority of packaging bags are also made from flat webs and are closed by a flap with a self-adhesive layer.
  • the outer layer of the packaging bag consists of a plastic on which the adhesive does not adhere too strongly, it is no problem to open and close such a bag several times. Bags with side gussets are closed again after the first opening by folding over the opening edge.
  • the invention is based on the object of proposing a reclosable packaging bag which can be produced in the simplest manner and at low costs.
  • a packaging bag which is characterized in that a carrier is permanently attached to one side of the bag, that a section provided with a self-adhesive layer made of a flexible material is removably attached to the carrier and that part of the carrier and a portion of the section protrude beyond the opening edge of the bag.
  • the bag can be made from any material, including paper, and that the carrier with the self-adhesive section can be a commercially available self-adhesive label.
  • the carrier has a dividing line which is designed as a weakening line or divides the carrier into two parts and which extends at least approximately parallel to the opening edge. This makes it easier to pull off the edge of the bag protruding part of the carrier when the bag is closed for the first time.
  • the carrier and / or the section have a recess which extends from the edge of the carrier and whose apex lies in the region of the dividing line. This design prevents the self-adhesive section from being pulled off unintentionally from the part which is inseparably connected to the bag when the bag is closed for the first time.
  • the flexible material of the packaging bag has at least one layer of paper, which is located on the outside of the packaging bag, or it consists entirely of paper.
  • the bag can have gussets.
  • its opening edge can be designed as a sealing edge.
  • FIG. 1 shows a packaging bag according to a first embodiment of the invention in a perspective view of its rear side
  • FIG. 2 the bag according to the first embodiment, seen from the front, before closing,
  • FIG 3 shows the bag according to the first embodiment seen from the front, after closing
  • FIG. 4 the bag according to the first embodiment, seen from behind, after reopening
  • FIG. 5 shows a packaging bag according to a second embodiment of the invention in a perspective view of its front side
  • FIG. 6 shows the bag according to FIG. 5 during the first opening
  • FIGS. 7 and 8 each show a section of a strip of a carrier material than with labels for packaging bags according to the invention.
  • the bags shown in FIGS. 1 to 6 are so-called block bottom bags.
  • the packaging bag shown in FIGS. 1 to 4 can be made of paper, for example, which is optionally provided on the inside of the bag with a thin layer of plastic, which ensures a certain degree of tightness and allows the material to be connected by sealing.
  • the bag has a rear side 1 and a front side 2 and its side parts preferably have side folds 3 in a known manner. At the lower end of the bag a bottom 4 is formed and at the upper end there is an opening 5 through which the bag is filled and emptied ,
  • a carrier 6 is permanently attached to the back 1, for example glued or sealed.
  • the carrier 6 is divided into two parts 8 and 9 by a dividing line 7, the dividing line 7 being exactly aligned with the edge of the bag in the example shown.
  • the dividing line 7 can completely penetrate the material of the carrier 6 or it can be designed in a known manner as a weakening line which does not completely penetrate the material of the carrier.
  • a portion of a flexible material provided with a self-adhesive layer adheres to the carrier 6.
  • this section is a commercially available self-adhesive label and is therefore referred to as label 10 in the description below.
  • FIG. 1 shows the packaging bag as it is delivered by the packaging manufacturer and, for example, delivered to a food processing company that fills the bag for the first time.
  • FIG. 2 shows the same bag, erected and ready for filling, the bag in this figure being rotated by 180 ° relative to the position shown in FIG. 1, so that the opening 5 is clearly visible.
  • the part 8 of the carrier 6 projecting beyond the bag edge is pulled off, which is facilitated by the dividing line 7.
  • the part of the label 10 protruding over the edge of the bag is bent over and the self-adhesive layer of the label 10 which is released by pulling off the part 8 of the carrier 6 is glued onto the front side 2 of the bag.
  • the bag closed in this way, as shown in FIG. 3, can now be delivered to the consumer.
  • the packaging bag can be opened in a simple manner by detaching the label 10 on the back 1 of the bag from the part 9 of the carrier 6 which is firmly connected to it and, as mentioned, has a release layer for this purpose.
  • FIG. 4 shows the packaging bag after it has been opened by the consumer, the bag in FIG. 4 again being rotated by 180 ° compared to the illustration in FIG. 3. If the consumer wants to close the bag again, he simply presses the part of the label protruding beyond the bag edge in the illustration according to FIG. 4 onto the part 9 of the carrier located on the opposite bag edge. It goes without saying that this process can be repeated almost arbitrarily.
  • the packaging bag according to the first embodiment described above cannot be closed tightly and is therefore, of course, not suitable, for example, for contents which contain liquid constituents.
  • a preferred use of this bag is in the packaging of solid foods, such as sandwiches, which are intended, for example, for delivery to air passengers.
  • the second exemplary embodiment of the invention shows a packaging bag that is sealed after the initial closure.
  • this bag is closed in a known manner by means of a sealing rim 12 when it is filled for the first time.
  • the carrier 6 is attached to the back 1 of this bag so that it does not adhere to the sealing edge 12.
  • the first opening of this bag can therefore be done in a simple manner by tearing off the sealing edge 12, which can be facilitated by a tear-open notch 13 and / or by lines of weakness, not shown, arranged in the packaging material. If the consumer wants to close the opened bag again, he removes the part 8 of the carrier 6 from the label 10, as indicated in FIG.
  • FIGS. 7 and 8 each show a section of a strip of a carrier material with labels for a packaging bag according to the invention.
  • a carrier 6 in the form of an endless band is used for the production of packaging bags according to the invention, on which the labels 10 are glued in a row.
  • the dividing lines 7 and the recesses 11 can also already be present in this strip.
  • the strip according to FIG. 7 is intended for the production of bags from a tube, the opening edges of the bags running transversely to the direction of production.
  • a strip according to Figure 8 is used for the production of bags from one or more webs, in which the Opening edge is parallel to the direction of the web, for example at the edge of the web.
  • the label 10 does not have to have the essentially rectangular shape shown in the exemplary embodiments described above, but can be of any design. For example, it can also be equipped with one or more tabs which facilitate opening. Furthermore, the label can be made of any material and can be transparent or see-through, for example.
  • the label can be printed, for example with information about its purpose and / or instructions for use. Of course, the label can also contain information about the expiry date of the package contents in a known manner. The same applies to the carrier 6.
  • the part 8 to be removed can have instructions for use and / or a tab.
  • On the part 9 of the carrier 6 which remains on the bag a note about the reclosing of the bag can be printed under the label 10, so that this note only appears after the bag has been opened.
