Definitions

  • pouches with pouch opening and with Velcro fastener (see document US-A-3 446 420) a number of shortcomings, for example such that both the first strip and on the second strip each as a Velcro fastener active side is exposed and exposed, so that especially when filling and packing the bag an undesirable contamination of the active side of the first strip and / or the active side of the second Strip can occur, for example if the bag with powdery material is filled and during of the filling and packaging process material particles in the ambient air.
  • Impurities don't just pull a strong one visual impairment after itself, but also limit the technical function and effect of the Velcro fastener.
  • the object of the present invention is to develop a generic bag so that the requirements of practice are satisfied. Of cleanliness, an attractive appearance, easy manageability and flexible to the Customizable amount removed from the bag for the first time Applicability of the reclosure guaranteed his. Finally, with the present invention also the goal to be pursued for customary available strip - shaped Velcro fasteners in to be able to easily apply to a on the one hand economically interesting and on the other hand, it works several times To provide reclosure.
  • the pouch according to the present invention can be first describe in that the active side of the first strip and the active side of the second Strip each other before opening the bag are facing each other and so to speak cover each other, so that especially when Filling and packaging the bag an undesirable Contamination of the active side of the first strip and / or the active side of the second strip in is prevented absolutely reliably, namely even if the bag with powder Material is filled and during the filling process Packing process material particles in the Ambient air. Therefore, of course, neither an optical impairment of the Velcro fastener another limitation of the technical function and Effect of the Velcro fastener.
  • the one with an adhesive layer provided back of the second strip covering Peel off the peel strip so that the adhesive layer is on the back of the second strip is exposed and the exposed back of the second strip can be fixed on the outside of the bag.
  • the pouch according to the present one Invention in its practical application, especially when you reclose the Bag, extremely flexible insofar as Arrangement of the two strips of Velcro to each other is not rigidly specified, but rather by the user himself depending on the the amount taken from the bag individually determined can be.
  • the Way of reclosing that is the Arrangement of the second strip of Velcro on the outside of the bag as well as the number of Fold lines essentially after that of the pouch withdrawn quantity:
  • the bag opening is for reclosing same after opening the bag by two fold lines of the bag to the outside of it with formation one edge foldable so that the back of the second strip after peeling off the peel strip on the other outside of the bag than that also preferably by an adhesive layer fixed back of the first strip can be fixed is.
  • the two are advantageously in about parallel fold lines in the reclosed condition of the pouch in expediently between the first strip and arranged the second strip, preferably with different distance from the upper end edge of the Bag and approximately parallel to the upper end edge of the Bag.
  • the peel strip covers the with an adhesive layer on the back of the second strip at least completely. hereby is guaranteed on the one hand that before the first Resealing the bag the effect of Adhesive layer is completely removed, so that a accidental attachment or sticking together as well ugly impurities are de facto excluded are; on the other hand, gripping and pulling the Peel-off strip immediately before the first Reclosing the bag opening made easier, if the area dimensioning of the Peel strip advantageously slightly larger than the area dimensioning of the one Adhesive layer provided on the back of the second Strip is selected because the (low) Protrusion of the pull tab can easily and easily grasped and pulled off with the fingers become.
  • the removal process can be facilitated or in addition to this accomplished be that the pull tab at least on his the side facing the adhesive layer with a adhesive-repellent smooth layer and preferably siliconized or made of silicone is.
  • the two Velcro straps that each advantageously approximately parallel to upper end edge of the bag are arranged and / or which advantageously with different distances are arranged to the upper end edge of the bag for the case should be provided that - contrary to expectations - a Mishandling or malfunction at "first" Velcro fastener is present; in this case it stands - as a replacement, so to speak - the second Velcro fastener to disposal.
  • the first strip of velor and the second strip of appropriately check-shaped trained microplastic material are the first strip of velor and the second strip of appropriately check-shaped trained microplastic material; also the reverse Case, that means the first strip is out expediently hook-shaped Microplastic material and the second strip is out Velor is possible.
  • one adjustable low strength of the sealing seam can have.
  • the bag 5 has a bag opening 6 (see FIG 2) and one to reclose the bag opening 6 serving after opening the bag 5 strip-shaped Velcro 7, 8, the Velcro 7, 8 a first strip 7 from Velor material and a second strip 8 hook-shaped microplastic material includes, both substantially parallel to the upper End edge 9 of the bag 5 in the area of the bag opening 6 are arranged; in particular is the first Strip 7 with its back 7r essentially parallel to the upper end edge 9 of the bag 5 in Area of the bag opening 6 through an adhesive layer established.
  • this adhesive layer is in front Protect all types of contaminants; is too through the facing arrangement of the Active sides 7w, 8w of the Velcro fastener 7, 8 as well by covering it with an adhesive layer provided rear 8r of the second strip 8 with a peel strip 4 a layered or stacked storage and storage of bags 5 possible without any problems, since neither through the active sides 7w, 8w of Velcro 7, 8 still with the an adhesive layer provided rear 8r of the second Strip 8 a connection or sticking together the layered or stacked bags 5 take place can (in the same way can also Garment or the like is not in the fine check-shaped structure of the respective active side 7w or 8w hook).
  • FIGS 8 illustrated the first embodiment Bag opening 6 for reclosing the same Opening the bag 5 by two fold lines 10, 16 (cf. Figures 2 to 4) of the bag 5 except for its Foldable outside to form edge 13, see above that the back 8r of the second strip 8 after Peel off the peel strip 4 (cf. transition from Figure 3 on Figure 4) on the other outside of the Bag 5 as that also by an adhesive layer fixed back 7r of the first strip 7 can be determined (see FIG. 5).
  • the two are essentially parallel fold lines 10, 16 arranged in relation to one another re-closed state of the bag 5 (cf. Figure 5) between the first strip 7 and the second strip 8 substantially parallel to upper end edge 9 of the bag 5 and with different distance from the upper end edge 9 of the Bag 5 arranged, the second fold line 16th compared to the first fold line 10 towards Bottom of the bag 5 is offset.
  • FIGS. 6 to 8 show how the Close bag opening 6 after re-opening for the first time the bag 5 is opened again. Because according to one feature essential to the invention, the adhesive force of the Adhesive layer on the back 8r of the second Strip 8 greater than the adhesive force between the Active side 7w of the first strip 7 and the active side 8w of the second strip 8, the second remains Strip 8 when reopening the bag 5 according to the Direction of arrow 14 on the outside of the bag 5 (see FIG. 6), so that the strip-shaped Velcro 7, 8 is separated.
  • the bag 5 is "folded back" around the Fold line 16 - corresponding to edge 13 - (cf. Figure 6) and by further “folding back” according to the Direction of arrow 15 around fold line 10 (cf. Figure 7) again in the open state (cf. Figure 8).
  • the two Velcro fasteners 7, 8 and 7 ', 8' serve insofar as the possibilities for Resealing the bag opening 6 as that Reseal in almost exact adaptation to the over time due to removal of material from the filling level in the bag 5 decreases is feasible.
  • the two Velcro fasteners 7, 8 and 7 ', 8 ', each substantially parallel to the upper one End edge 9 of the bag 5 are arranged (cf. Figures 9 and 10) or those with different Distance to the upper end edge 9 of the bag 5 are arranged (cf. the third embodiment in Figure 10), in the event that - contrary to expectations - mishandling or Malfunction in the "first" Velcro fastener 7, 8 is present; then stands for this case - as it were as a replacement - the second Velcro fastener 7 ', 8' Available.
