Definitions

  • the invention relates to a packaging bag made of a bag material formed from at least one layer, with a tear-open tab to form an opening.
  • the Swiss patent 427637 filed in 1964, describes a tetrahedral container made of a layer material with an opening which is closed by a tear-open tab welded onto the outer wall of the container.
  • the Swiss patent 636314 shows a beverage bag made of multilayer composite material, in which a container wall is provided with a continuous through to an inner layer pre-perforation. The pre-perforation is covered by a closure strip, which is connected in the pre-perforation with the inner layer. By tearing off the closure strip, the inner layer is torn open in the region of the pre-perforation and forms an insertion opening for a drinking straw.
  • Both beverage containers described have the common disadvantage that many users simply drop the closure strip after tearing off. This is of course undesirable.
  • the piercing of the sealing foil carries the risk of accidental puncturing of the container wall opposite the puncture opening, especially if the puncture opening lies in the region of the upper edge of the standing pouch in which the front and rear walls are relatively close to each other.
  • the exposed puncture opening hygienic concern, but there may accumulate impurities and / or bacteria that can get into the interior of the container when piercing the straw.
  • the present invention seeks to propose a packaging bag in which an opening can be formed without the need for a straw or the like has penetrated a layer and before the opening of the opening to form the opening Pollution is protected.
  • the tear tab is formed by a cut line of the bag material, that at least in the region of the tear tab on the inside of the bag material, a closure film is attached and that in a connection region the tear tab is connected to the closure film to pull to form the opening at the tear tab in the connection area.
  • the tear-open tab is formed by a cut line of the bag material, can be dispensed with the attachment of a separate tear-tab, for example by welding or gluing.
  • the closure film is torn in this area by a pulling force applied to the tear tab to form an opening through which the contents of the bag can be removed, for example, through a drinking straw inserted into the opening.
  • the point at which the opening is formed covered by the tear-open before tearing and protected from contamination.
  • the opening is made easier by a stress concentration occurring in the region of the tip when pulling on the tear-open tab.
  • the cutting line has two free ends and is in particular U-shaped.
  • the tear tab formed thereby remains connected to the packaging bag after forming the opening.
  • the sealing film is connected to the bag material in a connecting zone surrounding the tear-open tab, and the connecting region is arranged at one end of the tear-open tab and is connected to the connection zone.
  • the cutting line has no free end and defines a closed surface.
  • the tear-open tab can be completely separated from the packaging bag.
  • the sealing film is connected to the bag material in a connecting zone surrounding the tear-open tab, and the connection area is arranged at a distance from the connection zone.
  • the resistance decreases, which is opposed to the tensile force on the tear-open tab, and the tear-open tab can be completely torn off if desired.
  • the cutting line is interrupted on at least part of its length. This measure ensures that the tear-open tab is connected with the bag material and does not lift off the bag material prior to the intended opening procedure.
  • the cutting line is formed continuously on at least part of its length. As a result, the opening process is facilitated, especially when the continuous part of the cutting line is arranged at the free end of the tear-open tab.
  • the tear-open tab on the outside of the bag material has a sealing film projecting beyond the cutting line is covered.
  • the hygiene is further improved and it is particularly prevented that passes, for example, during storage of the packaging bag moisture under the tear tab.
  • the invention also relates to a method for producing packaging bags according to any one of the preceding claims, characterized in that a front wall material web, a closure film web and a back wall material web are guided at least approximately parallel to one another in a transport direction, that the front wall material web between a cutting tool and the front wall material web is guided by the closure film web and the back wall material web separating backing plate, that the cutting line is generated by the cutting tool and that in the transport direction of the cutting tool downstream connecting tools, the closure film web is connected to the front material web and the connection area is created.
  • connecting tools should be understood as meaning both welding or sealing tools and adhesive application tools.
  • This method has the particular advantage that, by virtue of the fact that the individual webs are guided substantially parallel prior to the attachment of the cutting line, special measures for mutual positioning of the webs in the transport direction can be largely dispensed with.
  • beverage packaging bag 1 Although the embodiments described below relate to a beverage packaging bag 1, the invention is not limited to beverage bags. Rather, inventive packaging bag for pasty Products such as soap or in the food industry, for example for fruit puree or yoghurt drinks are used. Also, such packaging bags for dry, especially granular or powdered products, not only in the food industry, but also, for example, in the field of chemistry, cosmetics or more generally the technology.
  • FIG. 1 shows a beverage bag 1, which is formed in this example as a stand-up pouch.
  • a raised tear-open tab 2 is visible, which releases the view of a closure film 6 arranged on the inside of the bag material in the region of the tear-open tab 2.
  • a torn-open 12 can be seen, in which a drinking straw 11 is inserted.
  • FIG. 2 shows the upper portion of the same beverage bag 1 in a cut along a vertical line view. Relative to those described below FIG. 3 corresponds to FIG. 2 a section along the line II - II.
  • the beverage container 1 consists of a front wall 4, a rear wall 5 and a bottom wall, which is not visible in this figure.
  • the pull tab 2 formed by a cutting line 3 of the material of the front wall 4 is visible, which is not raised in this view, but is flush in the front wall 4.
  • a sealing film 6 is fixed, for example by welding.
  • a connection zone in which the sealing film is connected to the front wall is designated by the reference numeral 9.
  • a connection area in which the tear tab 2 is connected to the closure film 6 and the below in connection with the Figures 3 and 10 will be described in more detail, is designated by the reference numeral 10.
  • FIG. 3 shows in a plan view of the upper portion of the beverage bag 1 of FIG. 1 before opening and in one opposite FIG. 1 enlarged scale.
  • the tear-open tab 2 is formed by a cutting line 3, which in the example shown has the shape of a lying U.
  • the cutting line 3 may be continuous or interrupted as shown, in the manner of a perforation line. Also, a combination is conceivable in which the cutting line 3 is interrupted on a route continuously and on another route.
  • the closure film 6 is formed in the example as a band that covers only just the area of the tear tab 2 on the inside of the beverage container.
  • the sealing film 6 can also cover the entire inside of the front wall 4 of the beverage bag 1. Furthermore, in FIG.
  • connection zone 9 is shown by way of example, in which the closure foil 6 is sealingly connected to the front wall 4 on the inside thereof.
  • the closure film 4 is connected to the tear-open tab 2, for example by welding.
  • This connecting portion 10 extends from a base of the tear tab 2, in which it remains connected after tearing with the bag material of the front wall 4, toward the free end of the tear tab 2, wherein it tapers to a point. In this tapered portion of the connecting portion 10 arise when pulling on the tear tab 2 voltage peaks in the sealing film 6 so that it starts to tear in this part and thereby the opening 12 is formed.
  • the front wall 4 and the rear wall 5 are spaced from each other. This is achieved in a particularly advantageous manner by holding the beverage bag 1 with one hand on the raised tear-open tab 2 while introducing the drinking straw 11 into the opening 12 with the other hand. Since most people are right-handed and therefore inclined to insert the drinking straw 11 with the right hand, the cutting line 3 is advantageously arranged so that the tear-open tab 2 is torn open from right to left, so that it is opened and held with the left hand, while the right hand holds and introduces the drinking straw. Often, the drinking straw 11 is in the delivery state outside the beverage bag removably arranged in such beverage bags.
  • the drinking straw 11 is removed from the beverage bag 1 before the tear-open tab 2 is torn open.
  • Such a procedure can be easily and reliably predetermined by the drinking straw 11 is arranged above the tear line 2 forming cut line 3 in the delivery state of the beverage bag.
  • FIGS. 4 to 7 one each along the line IV - IV in FIG. 3 show a sectional view, the opening process of the beverage bag 1 is shown in steps.
  • FIG. 4 shows the beverage bag in the closed state, with the cut line 3 is indicated on the right and then the tear-open tab 2 thereafter.
  • the closure film 6 is shown continuously from edge to edge.
  • the connecting region 10, in which the closure film 6 is connected to the pull-tab 2 is also indicated in this figure.
  • FIG. 5 is the tear tab 2 raised, but the sealing film. 6 is still unhurt.
  • FIG. 6 shows a situation in which the sealing film 6 is torn open in the connection region 10 and forms the opening 12.
  • FIG. 7 shows the beverage bag with a inserted into the opening 12 drinking straw eleventh
  • the tear tab 2 protects the closure film 6, and in particular the location where the opening 12 is formed, from contamination.
  • this protection can be improved even further by bonding or welding an additional sealing film over the region of the tear-open tab 2, such that the cutting line 3 is completely covered by the sealing film.
  • This additional sealing film is not shown in the drawings.
  • FIGS. 8 and 9 is an example of a manufacturing process for beverage bags 1 according to the invention shown schematically, wherein the letters a) to e) sections of a production facility are designated to be transported on the material webs stepwise in a direction indicated by the arrow 14 direction.
  • FIG. 8 shows a plan view of the material webs while in FIG. 9 a schematic side view is shown.
  • the material webs are arranged so that two beverage bags are arranged side by side so that their head portions are directed against each other and the bottom portions are located at the edges of the webs.
  • section a) are material webs, namely a later forming the front wall 4 of the drinks bag 1 web, a back wall 5 forming web, a film forming the closure film 6 and two later the bottom film 13 forming Unrolled webs of supply rolls and transported at least approximately parallel to each other gradually.
  • section b) are cut lines 3 in the later forming the front wall 4 material web by appropriate according to the double arrow 22 movable cutting tools 15.
  • the cutting tools 15 may have serrated cutting edges to form interrupted cut lines 3, so that the material still holds together between the cuts. So that the underlying material webs are not damaged by the cutting tool 15, a counter-plate 16 is arranged between the material web 4 and the other material webs.
  • a first, according to the double arrow 22 movable welding tool 17 is arranged, with which in the connection zone 9, the sealing film 6 is connected to the front wall 4.
  • a release film can be arranged, as indicated by the reference numeral 21.
  • the first welding tool 17 opposite a cooling plate 18 is arranged, is derived with the heat from the material webs.
  • a second, according to the double arrow 22 movable welding tool 19 is arranged, with which in the connecting region 10, the sealing film 6 is connected to the tear tab 2. Again, a release film between webs may be arranged to prevent unwanted welds. Also with respect to this second welding tool 19, a cooling plate 18 may be arranged.
  • the working sequence of sections c) and d) described here by way of example is not mandatory. It it is also possible first to weld the connection region 10 and then the connection zone 9.
  • an upper cooling plate 20 is assigned to a cooling plate 18 arranged in the figure below, in order to remove residual heat from the welding operations from the material webs.
  • the sections in which thermal operations are carried out may be arranged twice or more in succession in order to increase the capacity of the production plant.
  • section e) follow other sections in which edge welds attached and finally the finished beverage bags 1 are either separated from the webs or the webs are rolled up again to supply the beverage bags in this form a bottling plant.
  • FIG. 10 shows in a representation accordingly FIG. 3 another embodiment.
  • the cut line 3 open, so that in the base region of the pull tab 2 this remains connected after tearing with the bag material.
  • This has the advantage that the tear-open tab 2 does not have to be disposed of separately, but carries the risk that the beverage bag 1 will be damaged if you pull too hard on the tear-open tab 2 when tearing open.
  • the tear tab 2 is after FIG. 10 formed by a closed, circumferential cutting line 3.
  • FIG. 10 formed by a closed, circumferential cutting line 3.
  • FIG. 10 is in the example after FIG.
  • connection region 10 intended to form the opening 12 in the closure film 6 is not connected to the connection zone 9, in which the closure film 6 adheres to the inside of the front wall. Rather, the connection region 10 is according to FIG. 10 formed as an island and preferably designed tapering towards the free end of the tear tab 2 out. If the connecting portion 10 is narrow as shown, the opening 12 is also narrow when tearing so that after insertion of the drinking straw 11 this is practically sealed in the opening 12, so that no liquid can escape from the beverage bag 1 next to the drinking straw.
