Definitions

  • the invention relates to a closure for closing and reclosing a bag, in particular a bag for holding food, such as bread, confectionery or pasta, consisting of a strip which can be placed around a gathered neck of the bag in such a way that one end of the strip with the other side overlaps the outside of the bag and is fixed in this position.
  • the invention further relates to a bag which is provided with such a closure.
  • Such a known closure consists of a paper or plastic strip, in the lateral longitudinal edges of which rigid wires are integrated.
  • the rigidity or elasticity of the wires is chosen so that the strip, if bent from a flat position, remains in this bent position.
  • Such a strip is therefore stiff and inelastic. This makes it possible to use such a strip to close a bag.
  • Special devices, so-called clip aggregates are used for mechanical closing, which first gather a bag a few centimeters before its open end and, depending on the content, U-shaped strips (clips) with relatively thin wires - thickness approx. 0.6 mm with light content - or relatively thick wires - thickness approx. 0.8 mm with heavy contents - bend tightly around the gathering.
  • Common strip-shaped clips have a length of up to approx. 5 cm and a width in the range of up to approx. 10 mm.
  • Bags within the meaning of the present invention are understood to mean any type of container, for example also bags, made of plastic or paper, which are used in particular to hold food, such as bread, confectionery or pasta.
  • a typical example is sliced bread, in which several bread slices are packed in a bag.
  • individual slices of bread can be removed one by one; after removing these slices, the bag can be closed again so tightly by the clip that the bread slices remaining in the bag can be kept fresh.
  • a further considerable disadvantage is that recycling of such wire clips is practically impossible, since a separation of the wire from the paper or plastic is necessary, which would make considerable technical effort necessary. Furthermore, the production costs of such wire clips are relatively high, since wire and paper or plastic have to be processed into a clip band in complex machines. The transport costs for such a wire clip tape are also relatively high, since a wire clip tape is both relatively heavy and relatively bulky due to the wire.
  • the plastic adhesive strips have a thickness of approximately 0.06 mm.
  • the plastic adhesive strips are placed around the gathered neck of the bag such that the two ends of the folded adhesive strip face each other on the adhesive side. The opposite ends are then placed approximately congruently on one another and adhere to one another so tightly that this closure can usually only be opened by destroying the sealed adhesive strip. Resealing is then no longer possible.
  • Adhesive strips must be attached to the bags transversely to the packaging direction.
  • Automatic tape sealing machines can therefore only be integrated into a bag filling machine with relatively great effort. These machines are primarily designed as independent machines that are either mechanically or electrically synchronized with a bag filling machine and positioned at right angles to the end. The filled bags must therefore be transported outside the control of the bag filling machine, for example via a conveyor belt, to the automatic sealing machine, which can result in a relatively high number of faults.
  • Such a bag closing adhesive tape is known from document DE-U-86 28 413, which, in order to make it easier to open the ends of the closure adhering to one another via the adhesive sides, is not provided with an adhesive layer over its entire brow. As a result, there is an adhesive-free area on at least one side, in which the opposite ends of the closure do not adhere to one another. To open the lock it can be gripped at the adhesive-free areas of the two ends and the ends can be pulled apart.
  • This closure made of thin, limp film material also has the disadvantage that when the ends sticking to one another are torn apart, it cannot be ruled out that the adhesive tape will tear or severely in the adhesive areas separated from one another due to the great adhesive force of the two mutually adhesive sides coated with adhesive in each case is deformed.
  • the opened closure is a thin, sticky, pliable strip which, if it is to be used again to close the pouch, must be carefully set aside.
  • the wire clips can be pulled off a roll, cut off and shaped into approximately U-shaped clips. These are placed on the gathered necks of the bags, and one end of the wire clip is placed over the other by a mechanically simple bending process.
  • a clip closure tape for bags which consists of a flat, elongated strip made of flexible plastic, which has reinforced longitudinal edges which are thicker than the area in between. Transversal nominal crease lines are provided which ensure that the strip can be easily folded over at very specific points.
  • the plastic material is selected so that the strip can be folded and, after folding, develops the lowest possible restoring forces and also offers a certain resistance to bending back.
  • the strip itself is not provided with an adhesive or coated, but there are holes in the tape through which an adhesive label can be applied if the closure is in place. A pin can also be inserted through the hole in order to fix the closure.
  • Fixing such a closure in its end position using an adhesive label or an adhesive to be applied subsequently is extremely complex since, in addition to the necessary clip unit, an adhesive metering device which must be synchronized with the clip unit must be installed. Resealing such a closure would also make it necessary to reinsert the adhesive or to reapply a previously torn adhesive label.
  • a device for inserting the Locking pin to be installed in the clip which must be synchronized with the clip unit. After opening the lock, both the opened lock and the pin must be carefully set aside to enable the lock to be closed again. This variant is also complicated and its handling is cumbersome.
  • a band-shaped bag closure which is coated with a pressure sensitive adhesive.
  • This band is provided with transverse perforation marks at certain intervals in order to shorten or cut the band accordingly.
  • This adhesive tape is also placed around the neck of the bag in such a way that the opposite ends, with the sides coated in each case with adhesive, come to lie against one another in an adhesive manner.
  • the protruding end regions can then be cut off at corresponding perforation lines, but for this purpose care must be taken precisely when making the contact that the perforation lines of the ends adhering to one another lie congruently with one another. This requirement alone would require highly precise and therefore complex equipment for mechanical application.
  • This pouch can only be opened by destroying the adhesive seal, so it is hardly possible to close it again.
  • the object is achieved in that the strip is provided on one side with a pressure-sensitive adhesive at least in the overlap region of the ends, the bond of which to the strip is more intimate than the bond that occurs when the outside of the pressure-sensitive adhesive is applied to an area of the pressure-sensitive adhesive that is not covered by the pressure-sensitive adhesive
  • the strip is pressed, the adhesive force of which is set such that the overlapping ends adhere to one another firmly but detachably by hand, the material of the strip being selected such that visible changes in the material structure are present after the closure has been opened once, and that on the side of the strip on which the pressure-sensitive adhesive is present, there are areas free of adhesive at those points where clip-sealing units act.
  • a pressure-sensitive adhesive By providing a pressure-sensitive adhesive, the adhesive force of which can be adjusted, such an adhesive force can be provided for the respective application that the bag remains securely closed, but the adhesive bond is nevertheless easily detachable by hand.
  • Securely closed means that after the Betiteis has been filled by the manufacturer with a good and then closed, the closed closure becomes sealed during the subsequent treatments, such as packaging in transport containers, removal from transport containers, laying out in sales outlets, and grasping for visual inspection by the operator Buyer, does not open.
  • a pressure-sensitive adhesive is an adhesive that remains permanently sticky and tacky and by contact pressure adheres to a substrate. The adhesive bond can be released without destroying the bonded substrates.
  • the adhesive force depends on the type and quantity of the goods to be packaged and the type of handling between filling and closing the bag by the manufacturer and purchase by the buyer. If one falls back on the example of the packaged bread slices mentioned at the beginning, it is known that customers in particular research the expiry date of the consumption of the bread when buying, whereby such bags are then gripped at different points, not always by the closure reaching end area beyond the gathered neck.
  • the holding force is set so that handling is possible without opening the lock.
  • the bond between the pressure sensitive adhesive and the material of the strip is selected so that it is more intimate than the bond that results when the outside of the pressure sensitive adhesive is pressed onto an area of the strip not covered by the pressure sensitive adhesive.
  • This can be achieved, for example, in that, seen over the thickness of the pressure-sensitive adhesive layer, there is an adhesive force gradient, that is to say the outermost layer of the pressure-sensitive adhesive sticks less strongly than the layer which is in direct contact with the material of the strip on the inside. This then ensures that when the closure is opened, parts of the pressure-sensitive adhesive do not detach from the strip and remain at the adhesive bond. This then ensures that such a closure can be opened several times and securely closed again.
  • the material of the strip is selected in such a way that there are visible changes in the material structure after the closure has been opened once, it is ensured that the purchaser recognizes even a single opening and reclosing.
  • This measure opens up
  • the person skilled in the art can flexibly adapt to the particular circumstances of the bag or the goods to be packaged. If the packaged good is, for example, a sterilized good that is exposed to an accelerated aging process, for example by opening a bag once through contact with atmospheric oxygen or moisture, the material of the strip, at least on the outside, on which the adhesive lies, can be so be designed such that a single loosening of the closure causes streaking or creasing, or causes such structural changes that they immediately catch the eye.
  • the pressure exerted on the folded end when it was being closed, which was necessary to bend the wires, can now be used to create the necessary pressure, which is applied to the inner side of the overlapping end of the strip, which acts on the outer side of the other end is placed in the overlapping area, press firmly accordingly.
  • the adhesive bond is stronger if a high contact pressure is exerted.
  • the adhesive force is adjusted by appropriate formulation of the adhesive or by UV radiation.
  • the variant of UV radiation enables subsequent crosslinking of the PSA already applied to the strip until the desired adhesive force for the respective application has been achieved.
  • the pressure-sensitive adhesive is a hot-melt adhesive.
  • This measure has the advantage that a hot-melt adhesive is easy to handle and process, because this hot-melt adhesive only has to be briefly heated when applied to the strip. In particular, this opens up a simple mechanical production of the clip band. As previously mentioned, the holding force can then be adjusted accordingly by UV radiation.
  • the use of a hot melt adhesive also has the considerable advantage that it works without solvents must be what is desirable in environmental and workplace terms.
  • the hot-melt adhesive is an acrylate-based agent with UV-active copolymers.
  • the material of the strip on the outside is so brittle that visible, remaining changes in the form of folds occur when the closure is bent open.
  • this measure has the considerable advantage that the desired changeable material structure can be achieved in a very simple manner in terms of production technology.
  • so-called coated paper is used, the outer sides of which have glass-like micro-layers.
  • the glass-like micro layer on the outside is stretched or stretched when it is put on.
  • the glassy microlayer can follow this movement without any visible changes.
  • this stretched layer is compressed, which leads to a clearly visible formation of folds which is permanent and does not disappear even when the closure is closed again.
  • such a glass-like microlayer also represents a relatively smooth layer, which is involved in the adhesive bond with the pressure-sensitive adhesive in the overlap area.
  • This adhesive bond is less strong than the bond on the inner side of the pressure sensitive adhesive layer with the corresponding surface of the strip.
  • Even a very slight gradient of adhesive force across the thickness of the pressure-sensitive adhesive layer can be sufficient to ensure the above-mentioned mode of operation in the case of multiple opening and closing, ie to prevent pressure-sensitive adhesive regions from detaching from the adhesive-side side of the strip when the closure is opened.
  • areas free of adhesive are provided on both sides along the longitudinal edge of the strip.
  • adhesive-free areas are provided in the outermost end area of the strips.
  • This measure has the advantage that the outer end of the closure, which overlaps the other end when the closure is in place, is not adhesively connected to the latter in the outermost end region. This makes it easy to use a fingernail or even to grasp a finger, namely by bending up this end area, which is not provided with adhesive, and which acts as a kind of pull tab, and to open the closure.
  • the strip has at least one recess on one side, in which the adhesive is received.
  • This measure has the advantage that the adhesive can be applied to the strip very easily in terms of production technology.
  • the mass can be introduced into the recess in a very simple and precisely aligned manner, particularly when using hot-melt adhesives.
  • this depression can be created simply by embossing, for example.
  • the strip consists of a paper or a plastic material.
  • This measure has the advantage that a large selection of materials is available to the person skilled in the art in order to meet the requirements of the invention, in particular to make the desired material change clearly visible when the closure is opened once.
  • composite materials can be used in which the outer side is so sensitive that at least one structural change is clearly visible when opened once, even with adhesives with low adhesive strength.
  • stronger adhesives it can even be provided that parts of the material become detached and adhere to the adhesive layer, which makes it particularly easy to prove that the closure has been opened at least once, which is particularly significant for safety and guarantee reasons. Paper or plastic strips on which an adhesive is only available in relative small quantities have to be applied are therefore recyclable.
  • paper or plastic material with a basis weight of approximately 100 to 400 g / m 2 is used.

  • paper or plastic materials are used in strips about 10 to 20 mm wide.
  • This measure has the advantage that sufficient width of a closure against tearing can be achieved in this width with common paper and plastic materials. At the same time, this breadth also opens up the possibility of applying legible information, such as the packaging date, on the sealing strip.
