Definitions

  • the invention relates to a reclosable packaging for wet wipes or the like, made of a moisture-impermeable film, in the substantially flat top of which a tear line or a die cut is punched, which is covered by a larger flap, adhering to the material of the top, of the flap , the first end of which is permanently connected to the upper side by means of a weld or adhesive seam.
  • Such packaging made of a plastic film is known in principle from DE-A-28 00 165.
  • the packaging should be able to be closed again vapor-tight after each removal of a damp cloth, for which the sealing flap coated with a pressure sensitive adhesive is used. So that the pressure sensitive adhesive does not adhere to the top cloth, the material strip punched out of the top of the packaging to form the removal opening has not been removed. When the flap is pulled up, this strip of material sticks to it and covers the opening when it is closed again.
  • EP 0221 168 B1 proposes that the part punched to form the opening should not be completely punched out, but that one side of the removal opening, which forms the joint between the closure flap and the top of the pack, should not be punched in order to strip the material on this side to be made in one piece with the top of the pack. Due to this one-piece design, the material strip comes into better alignment with the removal opening even when it is reclosed.
  • an aluminum composite film as the moisture-impermeable film, the density of which is far greater than that of a polyethylene film.
  • an aluminum composite film disadvantageously occurs in the area of the punching, i.e. corrosion in the area of the tear line or the die cut, since the aluminum with the soaking liquid for the wipes, e.g. made of nonwoven, reacts.
  • Another disadvantage of the packaging consisting of plastic composite film is that it is not possible to pack goods with high perfume contents or alcohol (up to 40%) in such composite films, since the properties of the film do not form a satisfactory barrier layer for these liquids.
  • the moisture-impermeable film consists of an aluminum composite film and that a liquid-impermeable sheet is arranged between the flat top of the film and the wet wipes, which covers the tear lines of the die cut and in a significant manner extends the edges of the die cut, the area of the sheet being equal to or greater than the area of the closure flap.
  • the width and length of the insert sheet must in any case be smaller than the width and length of the closure flap, since this would no longer adhere to the surface of the package when the package was reclosed.
  • the skilled person is set narrow limits for the dimensioning of the plastic cutout when optimizing the known packaging. This also means that a high level of accuracy in the positioning of the plastic cutout must be maintained in the manufacture of the packaging.
  • the reclosable packaging according to the invention does not have these disadvantages and, moreover, it has the advantage that it is cheaper or easier to produce than packaging with a closed inner bag for holding the wet wipes, and the accessibility of the wipes allows it without great effort.
  • the tear line or punching is covered by a sheet of a plastic film or an aluminum composite film, the dimensions of the insert sheet being chosen such that it generously overlaps the tear line or punching. Due to the degree of filling of the packaging with the cloths, the sheet is pressed against the inside of the packaging film, so that no liquid can penetrate into the area of the punchings. This avoids liquid leaks from the punch holes and corrosion of the aluminum composite film used as the packaging sleeve.
  • an even higher level of tightness can be achieved if the sheet between the damp cloths and the flat inside of the film is permanently connected to the underside of the film in the region of its edge zones and has an opening (punched-out) for removing the wet cloths is smaller than the outline given by the tear line or the die cut.
  • a cover flap is also pulled off along the stamped portion, which at the same time exposes the removal opening of the sheet.
  • the packaging consists of a moisture-impermeable plastic-aluminum composite film, the ends of which are connected by means of weld seams 1 and 2 in a manner known from the prior art.
  • an opening is provided, through which the contents forming the packaging can be removed.
  • a removal opening 4 is used, which can be opened and closed again by means of a closure flap 5.
  • the closure flap 5 is coated with a pressure-sensitive adhesive 6 and welded along its narrow side by means of a weld seam 7 on the upper side 3.
  • a handle tongue 8 not coated with adhesive is provided on the opposite narrow side.
  • the closure flap 5 is larger in outline than the removal opening 4, to which it is arranged centrally, so that the closure flap 5 overlaps the edge of the removal opening 4 on all sides and thus seals in the closed state.
  • the removal opening 4 is punched, but the punched-out part has not been removed and can come into contact again when the closure flap is closed and thus covers the top cloth in each case as a covering tongue 9.
  • perforation lines can also be provided in the upper side 3, but the area facing the grip tongue 8 is fully punched out so that the cover tongue 9 adheres to the closure flap 5 when opened.
  • the cover tongue 9 is not punched at its end opposite the grip tongue 8, but is here connected in one piece to the material of the upper side 3.
  • the ends of the legs 10, 11 of the punching or perforation thus end blind.
  • This one-piece arrangement ensures that when closing the covering tongue comes to lie exactly over the opening 4, that is to say completely covers the opening 4.
  • the legs 10, 11 of the punching lines end at or in the weld seam 7, the stiffening or reinforcement takes place, thereby preventing tearing when opening.
  • the ends of these punch legs 10, 11 can end in arches 12, 13 directed outwards to the side, thus preventing tearing due to the notch effect (see FIGS. 4, 5).
  • These sheets 12, 13 can also be directed inwards without the punch leg ends touching.
  • the weld seam 7 is stepped, i.e. there are two lateral areas 7a offset from the central area, each provided on both sides of the cover flap 9, each also offset from the ends of the punch legs 10, 11.
  • the closure flap 5 and thus the cover flap 9 adhering to it can only be destroyed without destruction Pull off the offset weld seam areas 7a so that the ends of the punch legs 10, 11 are completely relieved of tension.
  • the same mode of action that is to say a strain relief for the ends of the punch leg, is also achieved with the curved arrangement of the weld seam 7 according to FIG. 7; here, too, the train is caught by the offset lateral areas 7b when the closure flap 5 is opened.
  • an adhesive seam or an adhesive strip can in principle also be provided, the adhesive connection along this seam being significantly stronger than the adhesion to the edge regions 14 between the closure flap 5 and the top side 3.
  • FIGS. 8 and 9 Such embodiments are shown in FIGS. 8 and 9, in which the adhesive seam 7c between the closure flap 5 and the upper side 3 is relatively wide.
  • the punch legs 10, 11 extend into this adhesive seam 7c.
  • the packaging can also be simplified in that the separate weld 7 or adhesive seam 7c between the flap 5 and the top of the pack 3 is completely omitted, provided that only the two punch legs 10, 11 each run out in an arc 12, 13. If these arches 12, 13 are reached when the closure flap 5 is pulled off for the first time and each time it is pulled further, the tensile resistance increases by leaps and bounds, thus ending the process of opening in practical use.
  • the invention consists in inserting a liquid-impermeable sheet 16 between the stack of non-woven cloths 19 and the inside of the top of the packaging 3, as shown in FIG. 2 or FIG. 9.
  • This sheet has a larger outline than that specified by the removal opening 4 and is dimensioned such that its dimensions are equal to or larger than the dimensions of the closure flap 5.
  • the sheet can either be inserted loosely or, as indicated in FIG. 11, be glued to the underside of the upper side 3 in the edge regions 17a. However, this sheet 17 then has a removal opening 18 through which the cloths 19 can be removed after the tab 9 has been pulled off.
  • the sheets 16 or 17 can either consist of a polyethylene film or an aluminum composite film. In any case, the interposition of the sheets 16 and 17 ensures that the punching lines 10, 11 are covered with respect to the sheets 19 and thus no moisture emitted by the sheets can penetrate in this area. This prevents premature loss of moisture and corrosion in the area of the punching.
