MXPA06009258A - Flip-top closure for composite and cardboard packaging - Google Patents

Abstract

The invention relates to a flip-top closure for composite and cardboard packaging, which permits the automatic opening of a package by flipping open the lid of the closure. The closure consists of a frame-type base element (1), which is designed to be welded by its level underside (2) to composite or cardboard packaging (3) and a continuous peripheral overhang (4) that protrudes upwards in order to form a pouring neck with an interior opening. A cover (5) that flips open and closes is fixed to said base element (1). A tongue (7) that is pivotally mounted on the base element (1) extends over the interior expanse (6) of the overhang (4). Friction-fit elements (8) act between the tongue (7) and the cover (5) to pivot said tongue (7) downwards by force when the cover (5) is flipped open, thus tearing and pivoting away a piece of the packaging lying below said tongue.

Description

made in the composite packing that conforms in its shape to the opening for the light of the closure, which is then sealed again afterwards, with a coating of the membrane. Only then the closure is placed over the hole drilled in the gasket, so that the membrane liner is removed when the lid cover of the closure is oscillated. To do this, for example, a guide is extended in the opening of the base element. This is equipped on the upper part with a push button, which the user can press with his finger, after which the guide moves downward and thereby tears and presses down the membrane liner. However, this does not lead to an opening for very clean external flow and the guide extends diagonally downward in the opening for flow after being depressed downward and consequently obstructs the flow unless it is pushed again or removed by the flow. cutting or tearing, which can only be done with difficulty. In addition, the descending oppression of the membrane coating with the finger is not always hygienic. The fingers can sometimes get dirty and the unwanted bacteria can always reach the liquid, not intentionally, from the fingers. In another variant, the composite package is extremely weakened at the point, where the closure is either glued or welded. For example, the sheet material is perforated in a through manner except for the coating of the related membrane. This, however, requires extremely precise drilling tools and drilling machines. If too deep a perforation is made, the coating of the membrane can be damaged or cut through and the composite package can no longer be sealed in a germ-free manner. If a very shallow perforation is made, then consumers may have trouble opening the package and can open it only by tearing away the closure of the composite package with great force. Another pre-treatment makes use of a laser technology. Using a laser beam, the final piece of the composite gasket to be perforated or to be removed is weakened, so that the seal still remains intact leaving the membrane coating undamaged. Even this pre-treatment is problematic and expensive. The laser beam must be tuned exactly to the laminated metal sheet, so that it is neither too weak nor too strong. But since the laminated metal sheets show certain tolerances in their resistance due to their manufacture, the adjustment for the perforation as well as the weakening with the help of a laser beam becomes an additional problem. In this way or in this way, expensive machines and devices are necessary.

In addition, the pre-treatments, no matter what method they are made of, will be made exactly at the correct point of the sheet metal, and consequently, the plastic closures should be placed precisely on these pre-prepared points. -treated To do this, a great effort of engineering is needed, which consequently causes a great cost. Another disadvantage of the standard solutions is that after the first oscillating movement of the part of the lid, the closure must be opened by means of a separate manipulation, especially by pressing the membrane liner with a bare finger. However, this method of opening the membrane coating is not hygienic and in addition, the coating of the membrane is not always completely and cleanly released from the area of light with respect to the internal part of the projection margins. Instead, the membrane liner is removed by tearing along the length of the closure opening where something in the intermediate range is not pressed down into the internal space of the composite package. This leads to a formation of ridges on both sides, which project downward on the inner side of the composite packaging and alter and restrict the outward and clear flow of the contents. If the composite packing is oscillated very 6 strongly in the outlet position of the flow, then there can not be enough air left inside the composite gasket, due to the too sticky design of the opening. This leads to a bubbling outflow, that is, to a discontinuous, jet-like external flow of the contents, which makes it difficult to place a proposed amount in a glass container or in a jar. None of such closures is available, which provides such a large peak, through which a soup spoon or other spoon of similar size can be inserted. The known cardboard package for corn flakes and similar products is thus a simple cardboard package for a plastic bag held within the package. For the opening, the cardboard package must be removed by tearing with the hand, so that it can be opened on top by the unfolding of the folded margins or also the tearing of the pack along a perforation. Only then can you hold the plastic bag inside, pull it out a little, and then cut a pig from the bag with scissors or a knife. The contents are then poured out by means of tilting and light agitation of the cardboard package, which, however, is done in a relatively uncontrolled manner. If such a pack is opened once, it can not be sealed again so clean Likewise, a closure with a pouring opening of adequate size could be desirable, ie with at least 10 cm2 up to 20 cm2 of pouring opening, which can be sealed again. For the contents to be extracted with a spoon, the closure must have such an opening, that is, possibly with an even larger spacing, so that a soup spoon or other measuring spoon can be inserted into the opening and the contents be extracted. Such a closure could then be suitable for the composite bag and for a single cardboard package of all powdered products, such as for milk powder, beverage concentrates, rice, flour, and food as well as non-food products which have a similar consistency. Because the seal is easier to achieve for granular products, essentially thinner laminates can be used for the packing of the liguids, and the composite packing can also be opened by tearing then relatively easily. The known plastic closures have also proven that they will be inadequate in a totally different aspect. First, the peak for outward flow of the closures does not always have an advantageous mode, so that when the pour is stopped, the liquid trickles down on the outer side of the peak and then it flows down over the composite packing. This outflow disorder is very annoying, because frequently the entire front side of the package becomes fouled. The top part of many standard closures is also not reliably held in the open position of the lid, so that the lid becomes loosened in the region of the inner joint between the lid and the bottom due to the stresses of the material and alters the flow stream outward, unless one purposefully holds the lid in the open position with one hand. In many cases, one hand is necessary to maintain the composite and pour packing, while the other hand holds a glass in which the liquid is to be poured. In such cases, no hand is free to keep the lid open and with the hand for pouring, the lid can be held simultaneously in its open position with great difficulty. In addition, the standard spill closures have less favorable sealing arrangements for the user, which can ensure the first opening ie the first swing of the top of the closure. In some solutions, a guarantee tape must be removed by detachment, which must be held with two fingers. In practice, however, this has proven to be very difficult. For example, if the user has applied hand or cream lotion to their hands, then it becomes difficult for them to remove by tearing the warranty tape, because their fingers are greasy. Opening the closure with gloves is also not possible. Finally, the re-positioning of the seal is not satisfactory either, because the closures themselves are not sealed sufficiently after the oscillation of the lid parts. Brief Description of the Invention Therefore, it was intended to provide assistance to the aforementioned problems and to the modality of an oscillating top closure for a composite package and a cardboard package, which, during opening, enables a complete opening and provided, clean, automatic and absolutely hygienic of the laminated material or the cardboard over the spacing for the external flow and therefore, is handled without a pre-treatment of the laminated material. In addition, the closure for the outward flow, after the opening, should make possible a continuous flow, free of jets, of a suitably thick flow of the liquid. The closure must also be functional and can be manufactured in such large dimensions for composite packaging or cardboard packaging for granular or powder products, so that in its open position a soup spoon or any other measuring spoon can be inserted into the container. inside, with the purpose of removing a spoonful of the contents. Secondly, in a special modality, the closure for the outward flow must also provide a tamper proof, secure seal, by which one should also be able to open the closure easily the first time. In addition, the closure must also ensure that the lid part is reliably maintained by itself in its open and closed position. Finally, a spill should be ensured without a runoff of the liquid jet on the outer side of the spout and allowing a tight seal after use. The main task by itself is solved by an oscillating top closure for a composite package and a cardboard package to automatically open the package through the opening of the closure lid, which comprises a base element of the frame type, which , with its flat base that is going to be welded or glued on the cardboard packaging and a peripheral projection that projects upwards to form a support opening for the outward flow on the inside, as well as a cover that closes the support for pouring, placed on it oscillatingly and formed therefrom, for opening and closing on the base element, whereby this double-leaf closure is characterized by the fact that a guide, placed in an oscillating manner on the base element, extends over the 11 internal side of the projection, and that the means of forced closing are available between the guide and the cover, with the help of which the guide can be swung down in a direction opposite to that of the cover and which is then cut or It tears through the underlying packaging material. Brief Description of the Figures The figures show various modalities of such double-leaf closure in different views.

Detailed Description of the Invention Figure 1 shows first the base member 1 for a double-leaf closure as the first of the two extruded parts of plastic. This base element 1 constitutes a somewhat rectangular frame, which is welded to the base. or glued on a composite package or a cardboard package with its lower side 2. This base element 1 forms a projection 4 projecting upwards, which initially forms a support for the pour or for outward flow. In the frontal region, this frame is formed in a spout 31 with edges 32 for tearing, pointed removal. The internal side of the frame remains free and forms the cross section 6 of the passage, clear, of the support for outward flow formed by the frame. In the frontal region of the base element 1 it shows internal margins 30, directed inwards and projecting into the clear width, which act as stops, as will be explained later. In the rear region of the base element 1 are the two cylindrical bearings 16, 17, on each side on the inner side of the projection 4. These are proposed to accept the bolts, which will be explained later. The cylindrical bearings are U-shaped, ie they are open on one side. The front cylindrical bearings 16 are thus extracted out of the bottom side 2 of the base element 1 at an angle of approximately 45 ° opposite the bottom side of the base element 1 diagonally upwards and directed on the front part. Making the connection just below these cylindrical bearings 16, are the cylindrical bearings 17, which are removed from the base member 1 from the top at an angle of approximately 45 ° facing the upper side of the base member 1, however, diagonally downwards and directed on the front. Underneath the cylindrical bearings 16, 17, the rear closure of the base element 1 extends, which here forms an upper part 33, whose front angular face 34 aligns with the flat and inclined rear surface of the spacing 17. A sealing edge 35 it can be formed between the upper part 33 and the underlying part of the base element 1, which projects up and forward on the inclined surface 34. This sealing edge can be extruded in die from the same material, i.e., connected as a piece with the base element 1, but can also be subsequently extruded with a second extruded element. Figure 2 shows as the second injection-molded part of the double-leaf closure, a guide 7 and a cover 5, which form a part similar to an oscillating fin. On the front of the guide 7 an i-circular end is shown and in the margin of the guide a sharp blade 28, projecting downwards, is formed, which forms a piercing tip 29 projecting downwards in the tip of the guide. The sharp blade 28 is formed by a margin of the guide projecting downwards, which can be equipped with ridges on the inner side facing the edge 16. bottom side 15 of the guide plate for reinforcement. On its back side, the guide 7 joins with an oscillating shaft 11, whose diameter is approximately three times the thickness of the guide plate. The upper side 13 of the guide 7 therefore extends tangentially on the oscillating axis 11. Accordingly, the oscillating axis 11 projects beyond the guide plate on its underside to approximately two thirds of its diameter. In addition, the oscillating shaft 11 is dimensioned somewhat longer than the width of the guide 7, so that it projects a little further on both sides. The projecting fragments construct the bolts, which can be inserted from below into the cylindrical bearings 16 already described in the base element 1. The margin of the guide 7, which projects downwards as described above, forming a blade 28, can only be designed as high as the measurement of the diameter of the oscillating axis 11. The cover 5 is formed somewhat below and above the guide 7. On its rear side, it shows an oscillating axis 10, and as in the case of the guide 7, the upper side 12 of the cover 5 extends tangentially on the oscillating axis 10. The thickness or strength of the cover plate similarly measures approximately 1/3 of the diameter of the oscillating shaft 10, which has the same diameter of the oscillating axis 11 of the guide 7. The oscillating axes 10, 11 can be designed hollow on the lower part by Spraying reasons, for example, when they comprise a series of discs of evenly ed diameters, which are connected together by a thin external wall of the shaft. Between the guide 7 and the cover 5 are available means for the snap closure 8, which do what is necessary so that the guide 7 is forcibly oscillated downwards in a direction of oscillation opposite to that of the cover 5 by cutting or removal by tear an underlying piece of packaging. These means for snap closure 8 are obtained here by a retractable web 9. The guide 7 is connected to the lid 5 by means of a retractable web 9, whereby it is designed as follows: the retractable web 9 is fixed with one of its ends on the lower side of the guide 7 or formed directly therein. It then extends downwards along the edge, which forms the oscillating axis 11 along the length of the lower side of the guide 7 with it and from there the retractable band 9 is driven around the oscillating axis 11. downwards and then upwards and formed on the underside of the cover 5 with the oscillating axis 10, for example along the length of the corner between the oscillating axis 10 and the underside of the cover. In this case, the guide 7, the retractable strip 9 and the cover 5 form an extruded part in one piece. As a variant, the retractable band 9 can also be driven through a groove in the guide plate, which extends along the length of the guide plate. length of the corner between the oscillating axis 11 and the lower side of the guide, formed on the underside of the guide. The groove can show a cross section that is pointed downwards, and the end of the retractable band is then provided with a collar, with a cone shape in the cross section. It can be plugged in through the slot on the down side. After this, a strip with a cone-shaped profile is cut from the top in the groove near the collar, so that the retractable band is held firmly in the groove. The retractable band comes from the lower end of the guide and is then led around the oscillating shaft 11 and finally into the lower side 14 of the cover 5. It is formed at the corner and along the length thereof, which is formed from the lower side 14 of the cover 5 with the oscillating shaft 10 of the cover 5. If now the bolts of the oscillating shaft 11 of the guide 7 are adjusted in the cylindrical bearings 16 in the base member 1 and the bolts of the oscillating axle 10 of the cover 5 are adjusted in the cylindrical bearings 17, then it can be seen in figure 2 that during an oscillation of the cover 5, which has already been tilted upwards a little, due to the geometric arrangement of the cover 5 relative to the retractable band 9 and to the guide 7, the retractable band 9 is stretched and pulled around the oscillating shaft 10. The tension of the retractable band 9, which it is wound on the guide 7 around its oscillating axis 11, it creates a torque on this oscillating shaft 11, which then causes the formed guide 7 to oscillate from the position shown. In the same measures as the cover 5 is oscillated upwards and downwards, the guide 7 is also oscillated upwards and downwards. If the guide 7 is forcibly swiveled downwards, then the piercing tip 29 on the blade 28 first pierces the packing material below it, and thereafter the blade 28 further cuts from this opening, so that during the oscillation the guide 7 the underlying piece of packaging material is cut from the package and folded down, as will be described in more detail. The oscillating force of the guide 7 for cutting and folding down the packing material which lies below the guide 7, can be very different because of this, because the tensile strength of a retractable strip 9 made of plastic is very strong. high and the reaction forces are absorbed from the bolts, which can absorb very high shear forces. Figure 3 shows a detail in the base element 1, especially the cylindrical bearings 16, 17, for the rotational position of the guide 7 and the cover 5 in an amplified view. The rear screen of the base element 1 of FIG. 1 is shown here, especially section A in FIG.

Figure 1. Cylindrical bearings 16, 17 with U-shape are easily visible. Front cylindrical bearings 16 serve to accept the pivot shaft bolts 11 in guide 7. Agui, only one cylindrical bearing 16 is visible, while the Another cylindrical bearing, which is like an image to the mirror on the opposite side, is not visible. These cylindrical bearings 16 are extracted from the lower side 2 of the base element 1, at an angle of about 45 ° against the lower side 2 of the base element 1 diagonally upwards and directed on the front. On the rear side, on the rear side of the cylindrical bearings 16 arranged in the direction of the rear side of the base member 1, which forms the longer U-shaped arm, the rounding of the U is continued in an additional piece, of so that it encompasses a round bolt which is to be fixed in the cylindrical bearings 16 by more than 180 °. The pin is fixed by inserting it into the cylindrical bearings 16 from below with a slight expansion thereof and slides them into the almost hollow cylindrical bearing and is maintained therein. However, the rounding of the U can also be tangentially joined on the back side of the cylindrical bearings 16, so that a round bolt is effectively adjusted to an angle of 180 °. However, when the base member 1 is welded to a composite gasket with its lower side 2 or also when it is glued thereto, 21 then the pins of the oscillating shaft 11 are driven from the composite packing in the cylindrical bearings 16 and consequently, they are held in their position. In the operation, that is to say when the closure is activated, the forces act only in the direction of the semicircular wall of the cylindrical bearings, but not in the opposite direction, as explained below. Just below the cylindrical bearings, the cylindrical bearings 17 for the oscillating shafts 10 of the cover 5 are connected, which are removed from the base element 1 on the upper part, at an angle of approximately 45 ° against the upper side of the base element 1 diagonally down and directed towards the front. In the same way, these cylindrical bearings can be formed in their longer U-shaped arm in such a way that they encompass an assembly on the bolt 10 at an angle greater than 180 °. The bolts 10 are then secured in this by a slight expansion of the U-shaped arm of the cylindrical bearings 17. This is advantageous, because then the bolts 10 are held firmly in position. However, this stage is not absolutely necessary, because in the operation that is, while the closing is opened, the forces act only in the direction against the rounding of the cylindrical bearings with U-shape 17, as it will reach be clear again The longest, rear wall of the 22 U-shaped arm can also be designed to be flat. Under the cylindrical bearings 16, 17, the rear closure of the base element 1 is stretched, which forms a stop 33, whose front angular face 34 joins the flat, rear surface of the spacing 17. Between the fixing part and the underlying part of the base element 1 can form a sealing edge 35, which extends above the inclined surface 34 and lies very close to the oscillating axis 10 of the fixed cover 5. This sealing edge can be extruded from the same material. or it can also be extruded from a second elastic extruded material. Figure 4 shows in a schematic side view, how the cover 5 and the guide 7 are placed on the base element 1. The pivot shaft bolts 10 of the cover 5 are held in the cylindrical bearings 17 and the pivot shaft bolts 11 they are held in the cylindrical bearings 16 in the guide 7. When the guide 7 and the cover 5 are connected in a one-piece manner by means of the retractable strip 9, then first the guide is led through the base element 1 twisted from the top with the tip forward against the base element 1 at an angle of 90 °, after that it is rotated back by 90 ° and still in the vertical position up to the base element, the fragments of the bolt of its axis oscillating 23 11 on both sides are fixed in the corresponding cylindrical bearings 16 in the base element 1. Because the guide 7 extends downwards, the retractable band 9 is not stretched if the cover is oscillated back and allows the cover 5 handled in this retractable band 9 after this it is pushed back to its correct position and the fragments of the bolt of its oscillating shaft 10 can be fixed in the corresponding cylindrical bearings 17 in the base element 1. Figure 5 shows the double closure sheet in the assembled state, with the base element 1, the guide 7 and the cover 5, mounted on a composite pouch 3. When the cover 5 is completely closed, that is to say when the flap formed by it is completely oscillated downwards on the base element 1, then the retractable band 9 is not stretched, but rather loosely deploys around the oscillating axes in the guide 7 and the cover 5. In the state shown above, the cover 5 is already raised or has been slightly tilted upwards, and in this position the retractable band 9 is airtight. During a further oscillation of the cap 5, the pulling force acting on the retractable band 9 produces a torque on the guide 7, so that it is swung down in a direction opposite to the direction of oscillation of the cap 5 in the base element 1, as described below with greater 24 detail. In Figure 6, the described double-leaf closure is shown during the oscillation of the cover 5 or the flap formed by it. When the lid 5, as shown, is oscillated from the base member 1, then the retractable band 9 fixed or formed on its lower side 14 exerts a force on the retractable band 9 due to the geometric arrangement of the oscillating shaft 10 in the lid 5 As described, the retractable web 9 is wound around the oscillating shaft 11 on the back side of the guide 7 and fixed or formed at its lower end. The tensile force of the retractable band 9 produced by the oscillation of the lid 5 produces a torque on the oscillating shaft 11, around which it is wound, which is transferred to the guide 7 formed on the oscillating shaft 11. Consequently, the guide 7 is oscillated downwardly on the oscillating axis 11. While the cover 5 is oscillated in the clockwise direction in the figure, the guide 7 oscillates in the opposite direction, that is to say downwards in the direction in the counterclockwise direction in figure 6. When the double-leaf closure is welded or glued to a composite pack or a cardboard package, then the piercing tip 29 punches the pack just in front at the tip of the guide and thereafter the blade 28 makes the cut, along the length of the guide margin, the packing material that lies below the guide 7 of the packing material and thereafter, the guide 7 swinging downwards pushes down the cutting part of the packing material. While the lid 5 of the closure has been swung upwards, the cutting part of the packing material remains pushed downwards and consequently, the clear cross-section of the closure is released for reliable pouring of the contents of the package. Since the closure can also be designed large enough so that a soup spoon or any other measuring spoon can be inserted therein, it is also possible to remove the contents of the package by means of a measuring spoon. When the guide 7 is oscillated backward, the reaction forces act on the base member 1 and pull it away from the composite bundle. Therefore, if necessary, the base element may be composed of a wider frame, so that a larger surface for bonding or for welding becomes available on its lower surface, and thus the reaction forces Actuators can be absorbed more reliably, without tearing off the pouch shell. Figure 7 shows an advanced variant of the oscillating upper closure for two stage tear removal and the downward oscillation of a piece of the package. In contrast to the closure described at the beginning, the guide 7 shows here the front part 20, which is connected to the rear part 18 only by means of an internal joint 19, which extends transversely through the guide 7. This front part 20 can thus be swung down separately in front of the back part 18 of the guide 7. The front part 20 is provided with a blade 28 along the length of its margin, which extends downwards from the front part 20 and at the tip of the guide is formed a piercing tip 29. The blade 28 can be braced in front of the lower side of the guide 7 by means of radial ridges, so that it has a higher stability. At the rear part 18, the guide 7 has a recess 23. On the lower side 21 of the oscillating front part 20 of the guide 7, a retractable strip 22 is formed, which leads to the rear part from there by means of the internal articulation 19 and then through the recess 23 upwards to the upper side of the guide 7. This retractable band consists of the same material as the complete closure. Due to its thinness, it can be folded and due to the quality of its material, it has a high capacity to withstand tensile stresses. At its end, this retractable band 22 shows a hook 24 with barbs, curved upwards, which extends over the full width of the retractable band 22. The counterpart of this retractable band 22 27 it is present on the lower side 14 of the lid 5 as a retractable strip 25, with the same bending and strength properties. This is formed, not far from the oscillating shaft 10 of the lid 5, on its lower side 14 and is stretched from there in the direction of the front end 26 of the lid 5 and is slightly curved downwards. At its front end, it forms a hook 27 with barbs, effective over the full width. The geometrical arrangement of the guide 7 and the cover 5 on the base element on the one hand and the geometric arrangement of the retractable bands 22, 25 as well as the internal articulation 19 is now selected in such a way that in the case of the oscillating position of the cover 5, shown here, the ends of the retractable bands 22, 25 facing each other, can not be touched. On the other hand, if the cover 5 is oscillated downwards on the guide 7, then the barbed hooks 24, 27 of the two flexible retractable bands 22, 25 fit together and thereby produce a connection resistant to the tensile force. . In this embodiment of the oscillating upper closing, the retractable band 9 is designed in its length between the guide 7 and the cover 5 in such a way that it remains loose in the first phase of oscillation of the cover 5 and produces a force of traction only after an oscillated position of the cover 5 facing the guide 7 at an angle of approximately 30-45 °, and only then does the downward swing of the complete guide 7 begin. In 28 a first phase of oscillation of the cover 5, therefore, instead of this, the retractable bands 22, 25 are acting with a very high pulling force due to the acting force. The cap 5 thereby acts on its own with its full length as the lever and the distance from its oscillating axis to the point of formation of the retractable band 25 acts as the loading lever. As a result of this, the tensile force acting on the retractable web 25 is already multiplied by a factor of 4 to 6 against the oscillating force applied on the lid 5. This pulling force then acts on the retractable web 22, which causes the front part 20 of the guide 7 to oscillate downwards. The reaction force on this downward swing is expressed in an attempt that the back part 18 of the guide 7 oscillate forward. However, this is discarded with respect to the back part 18, because for this the base element 1 shows projections 30 on the part projecting inward, laterally, which are visible in figure 1, and in which both of the margins on the upper side of the back part 18 of the guide 7 are stopped. Consequently, a large oscillating force acts on the front part 20 of the guide. This front part 20 is also capable of perforating and cutting a strong packaging material, that is, making a semi-circular cut along the length of the blade 29 28 in the packing material. While this cut is still being made, the lid must be swung upwards by about 30-45 °, and then the joining of both retractable webs 22, 25 is removed by tearing for geometrical reasons, and both of the retractable webs 22, 25 are separated from each other. In order for the united to separate, the barbed hooks 24, 27 are shaped accordingly, so that they securely retain a slightly elevated oscillating position of the lid 5, while they make a sliding pass between after exceeding a certain oscillating position, because of the angle at which the retractable band 25 and its barbed hook 27 remain opposite the barbed hook 24 on the retractable band 22, an enlargement is provided with the increasing oscillation of the cover 5. Therefore, it is a matter of the mode of the barbed hooks 24, 27, so that they make a sliding pass with each other when the desired oscillation position of the cover 5 is reached. As soon as the sliding pass has been made, the guide 7 is oscillated downwards as a whole through the further oscillation of the cover 5 on the retractable band 9, because of this, it is now thought that the oscillation position of the lid has been reached. To illustrate this movement of the lid with its removal by tearing two stages of the packing material, the 30 figure 8 first shows the lid 5 and the closure guide in a schematic view as seen from one side, in the initial state with the lid 5 closed. It can be seen how the retractable band 22 with its barbed hook 24 is formed on the lower side of the front part 20 of the guide 7 and is led upwards through the guide 7. The cover 5 is oscillated downwards on the guide 7 and the barbed hook 27 on the retractable band 25, which is formed on its lower side 14, lies beyond the barbed hook 24. The retractable band 9 between both of the oscillating shafts 11, 10 on the other hand lies loose way, that is to say with a small game between its ends of fixation in the ends. Figure 9 now shows the cover 5 slightly oscillated away from the base element, ie also oscillated away from the guide 7, because the retractable band 9 remained in this oscillated position and no force was exerted. For this reason, the guide 7 is not yet swung down as a whole, instead of this, the retractable band 22 is pulled towards the underside of the lid 5 by means of the force of the retractable band 25 and because of the guide 7 can not be deflected upwards due to the projecting margin 30 in the base element 1, only its front part 20 is oscillated downwardly on the axis of the internal joint 19, as marked by the arrow. The 31 piercing tip 29 in the blade 28 in the front part, thus perforating the laminate extending down the guide 7 and when the front part 20 of the guide 7 is further downwardly oscillated, a cut is made in the packing material , along the length of the blade 28. As soon as this position is reached, the barbed hooks 24, 27 of the retractable webs 22, 25 slide when they have passed each other. At the same time, the retractable band 9 is tightened between the oscillating shaft 11 of the guide 7 and the oscillating shaft 10 of the lid 5. If the lid 5 is now further oscillated, then only the retractable band 9 is effective and the guide 7 it is oscillated downwards as a whole. The reaction forces in the oscillation of the cover 5 act on its oscillating axis 10, but they succeed only in the oppression of the oscillating shaft 10 against its cylindrical bearings 16 in the base element 1 and can not be exited by bending thereof. The first phase of the opening, in which only the front part 20 of the guide is oscillated downwards, is important for the perforation and tear removal of the packaging material, which is especially critical. Once this is done, the packing material can be removed by tearing relatively easily. Figure 10 shows an alternative embodiment for tearing in two stages of the packing guide 7. Here, the 32 The front part 20 of the guide 7, which can be swiveled in front of the back part 18 of the guide 7 around the internal articulation 19, is divided by itself into three sections 36, 37, 38, which are connected to each other by means of the internal joints 39, 40. The retractable band 22 is formed in the most frontal section 38 and travels therefrom downwards from the entire front region 20 of the guide 7 and thereafter through the recess 23 to the upper side of the guide 7. The retractable band 22 acts together with the retractable band 25 in the manner already described on the underside of the lid 5. Figure 11 shows this alternative embodiment of the guide 7 together with the lid 5 in a schematic view as seen from the side. Here the starting position is shown, in which the cover 5 lies on the guide 7 with the closure still closed and the retractable band 9 between the oscillating shafts 10 and 11 has not yet been stretched. If the cap 5 is now raised, then its retractable band 25 pulls it back due to the engagement of its barbed hook with that of the retractable band 22. The retractable band 22 pulls back with its end the most frontal section 38 in the guiding tip. But because the section can not yet be pulled back, it is deflected downward by the oscillation around the inner joint 40, as shown in Figure 12. Due to the short length of section 38 acting as the arm, good lever arms result, whereby the piercing tip 29 in the section 38 can exert a very high piercing force on the packing below it, so that this material is perforated. Once the perforation is made, the regions 38, 37 and 36 oscillate by an additional pull in the retractable band 22 and by an additional oscillation in the cover 5 downwards one by one, whereby the blades 28 formed therein withdraw by tearing or additionally cutting the packing material starting from the point of perforation. The retractable band 22 which extends below the regions 36, 37 and 38 and the tension therein, ensures that first only the most forward region 38 is downwardly oscillated, after which the region 37 and finally the region 36. Only when all of these regions 36-38 have been oscillated downward and the guide 7 has removed by cutting thus a U-shaped flap of the packing material, the engagement of the two retractable webs 22 and 25 is released as a result of the geometric conditions. From now on, the retractable web 9 acts on the back part 18 of the guide 7 and oscillates along the length of the guide margins whereby it cuts off the packing and the blade 28 formed on it further descends. The fin-shaped part of the package cut in this way is downwardly oscillated by the guide 7 and therefore establishes the route for the outward flow of the contents. Figure 13 shows the situation after the additional oscillation of the cover 5, when this is oscillated by approximately 80 °. The guide 7 which has been displaced approximately 20 ° in front of the base member 1 due to the retractable band 9 now hermetic, starting from an oscillating position of the cover 5 and thereafter oscillated exactly to the same extent as the cover 5 , it has thus, for an oscillation of the cover 5 of 80 °, that to have experienced an oscillation downwards of 80 ° minus 20 °, that is to say an oscillation of 60 °, as shown here. In the case of this oscillation, the guide 7 has additionally removed by tearing the underlying composite package 3 along the length of the guide margins and has further pushed it downwards. The measurement of the specified angle is only an example. The angle of oscillation of the lid, after which the retractable band 9 becomes airtight, can be selected. This depends on the selected geometry of the closure components, which can be adjusted to suit the conditions, that is, depending on the size of the closure and depending on the strength of the packaging material used, the angle of oscillation can be selected. The reaction forces, which act when the cover 5 is oscillated on the axes 35 The oscillating elements of the cover 5 and of the guide 7 exert just pressure on the oscillating shafts 10, 11 on their respective cylindrical bearings, so that there is no risk of the oscillating axes slipping out of these cylindrical bearings 16, 17, which are open on one side. Starting from the situation shown in figure 13, there is an additional oscillation of the cover 5 due to the tight retractable band 9 with a simultaneous oscillation of the guide 7 downwards in the same measure, so that finally the final position of the oscillation The lid 5 is oscillated by approximately 120 ° and the guide 7 is also oscillated according to this, whose downward oscillation started 20 ° later, down in 100 ° from the base element 1. Accordingly, in the event that the cover 5 has been completely oscillated, the guide 7 retains the fin-shaped part of the cut-off material cut downwards, so that the passage remains free for the outward flow. The oscillating shafts 10, 11 and the related cylindrical bearings 16, 17 can be designed and dimensioned in such a way that they develop a certain frictional force, which is applied to the same so that the cover 5 is maintained in the open or oscillated position. If the lid 5 is narrowly oscillated 36 again, then the guide 7 remains in the oscillating down position. The retractable band 9 is simply pushed down. During the oscillation again of the cover 5, the guide 7, in the case that it has been oscillated backward a little, is again descended again completely by the retractable band 9, in the position shown there. The seal of the closure, so that not even a single drop can come out, is secured by an elastic sealing edge 35, which is formed on the upper part 33 on the base element 1 and is pressed on the back with with respect to the smooth surface of the oscillating shaft 10. Figure 15 shows a modality of an oscillating upper closure with an alternative forced closing means 8, with the aid of which the guide 7 can be swiveled down to the cover 5 in FIG. the direction of the inverse of the clockwise, during the opening of the cover 5 with the cut or tear and the downward oscillation of the underlying packaging piece. These forced closing means are composed in such a way that the oscillating shafts 10, 11 form a gear bar on an axial section. For this, the oscillating axes 10, 11 of the cover 5 and the guide 7 in the base element 1 are shown schematically in a cross section in this figure. The guide 7 with its oscillating shaft 11 is fixed in the manner 37 usual from below in the cylindrical bearings in the base element 1. To do this, the oscillating shaft 11 is formed with hinge axes on both of its ends, which extend slightly on the guide 7 on both sides, while that it is designed as a gear bar between them, that is, over the full width of the guide 7. The oscillating shaft 10 of the cover 5 is similarly provided with articulation shafts on both sides, while it is provided with teeth over almost the full width of the cover 5 and forms a continuous gear bar. The guide 7 is placed in the base element 1 from below and the cover 5 with its oscillating axis 10 is placed in its cylindrical bearings in the base element 1 from the top. Because the U-shaped cylindrical bearings are arranged obliquely with respect to the base member 1, they can be placed just a little apart from one another, the teeth of the oscillating shafts 11, 10 can be made to engage while the oscillating axes in the cylindrical bearings are adjusted. If then the cap 5 on the base member 1 is oscillated, then the torque acting on the oscillating shaft 10 can be transferred to the oscillating shaft 11 and consequently to the guide 7 by means of the teeth; the guide 7 in the base element 1 can be made to oscillate downwards according to the same oscillating force, with which the cover 5 is oscillated 38 up, and this can tear the package and push it further down. A large torque can therefore be applied, because the teeth are effective over the entire length of the oscillating shaft. Figure 16 again shows an alternative embodiment of the already described variant with oscillating axes, which form a gear bar on an axial section, which makes possible the tearing in two stages and the downward thrust of the guide 7. For this, the Oscillating axes 10, 11 of the cover 5 and of the guide 7 in the base element 1 are displayed in a cross section. The lower part of the cover 5 is now, as shown in the embodiments given in figures 7 to 12, eguided with a retractable band 25 and the guide 7 with a front part 20 which can be swung away from it and a band retractable 22 formed on its underside. The retractable band is led through a recess 23 in the guide 7 on its upper side and provided with a barbed hook 24. All the elements are the same as in the case of an oscillating upper closure, which is shown in FIG. 7 to 12, except for the arrangement and arrangement of the oscillating shafts 11, 10 of the guide 7 and the cover 5. The guide 7 with its oscillating shaft 11 is placed in the usual manner from below in the cylindrical bearings in FIG. the base element 1. To do this, the axis 39 Oscillating 11 is formed with articulation shafts at both ends, which extend a little over the guide 7 on both sides, while the same is designed as a gear bar between them, ie over the full width of the guide 7. The oscillating shaft 10 of the cover 5 is similarly provided with articulation shafts on both sides, while it is provided with teeth almost over the full width of the cover 5 and forms a continuous gear bar . Contrary to the embodiment given in figure 15, the teeth on the oscillating shaft 10 of the cover 5 are only on a part of its periphery, as shown in figure 16. The cover 5 with its oscillating axis 10 is placed in its Cylindrical bearings in the base element 1 from the top. The oscillating axis 10 in the cover 5 then lies with an area in front of the oscillating axis 11 of the guide 7, where it does not show any teeth, instead it is smooth. Only after the cap is oscillated by a certain angle of about 20 ° to 40 °, that is, after the retractable strips have become actuated by the separate oscillation of the front part 20 of the guide, the teeth on the shaft oscillating 10 engage the teeth on the oscillating shaft 11 and thereby effect a downward oscillation of the guide 7 to the same extent as when the cover 5 is further tilted upwardly. 40 Figure 17 shows this solution with the lid 5 completely oscillated upwards. The teeth of the gear bar on the oscillating shaft 10 of the cover 5 have been coupled with those of the gear bar on the oscillating shaft 11 of the guide 7 and this is oscillated downwards by the upward oscillation of the cover 5. in the reverse direction of the clock hands. For this reason, the longitudinal margins of the guide 7 have cut or torn off the underlying packaging material and have pushed the strip of the packing material down further, thereby becoming free. When the lid 5 is closed, the guide 7 is oscillated back to its original position, and when the closure is opened again, it is oscillated down again and the strip is pushed down again by tearing or cutting the strip of the strip. packing material, so it makes the passage clear for the outward flow of the liquid. The active frictional force between the bolts of the oscillating shafts 10, 11 and the cylindrical bearings ensures for these closures that the cover 5 is maintained in each oscillated position. Accordingly, the closure can be opened and remain open, so that the composite package can be held with one hand and its contents can be poured in the desired amount while the other 41 hand remains free or can support some other container. If it is required to insert a measuring spoon into the opening of the closure with the free hand and remove a measured part of the contents, it is important that the closure remains in its open position. This closure can also be closed again in a simple and easy way by oscillating backwards the cover 5 again on the base element 1. Therefore, the cover 5 can be designed in such a way that it remains adjusted on the base element 1 when the latter is oscillated downwards, that is to say its margin is projecting somewhat downwards and on the upper part a slightly projecting margin can be flexed on the base element 1. On its rear side, the sealing edge 35 applies pressure on the smooth surface of oscillating shaft 10 and it provides a very good seal there. In the case of the embodiment with the sections of the gear bar on the oscillating shafts, a sealing band can be provided, which connects the upper side of the lid on the rear side with the base element 1 and consequently covers the shaft of toothed oscillation 10 of the lid 5 and it is airtight when the lid 5 is closed. Then the cover 5 is extruded with the base element 1 on this band and the guide 7 with its toothed oscillating axis 11 then forms the second plastic extruded part of the closure. Figure 18 shows a variant of how the closure 42 It can be extruded as one piece. For this, the base element is designed divided on its rear side and both of the frame assemblies 44, 45 that extend backward are somewhat dispersed away, here especially at an angle of 43 °. Both of the parts 46, 47 which are to be connected to the rear side of the base element, show a snap-fit mechanism on the end side, for example on the side with a barbed hook 42, which can be snapped into a corresponding formation of the piece 46 which lies on the opposite side. The cover 5 and the guide 7, which are connected to each other by means of the retractable band 9, are then extruded in the position shown as a piece with the base element 1. For this, the ends of the oscillating shafts 10, 11 are present directly before the openings of the cylindrical bearings and the end margins of the front face of the oscillating shafts are connected to the margins of the openings of the cylindrical bearings by means of several bridges 41 of fine material. The cylindrical bearings extend continuously through the frame 1 and open on the outer side of the frame 1 with the holes 48, 49. Therefore, the cylindrical bearings can be deformed on the outside by means of slides, which retract outwards after molding. Bridges of material 41 cause, 43 on the one hand, the nature of a piece of the complete closure, and on the other hand the cover 5 and the guide 7 are placed opposite the base element 1 so that a subsequent placement with the help of a robot is omitted, which could be necessary in the case of a separate molding of the base element 1 on the one hand, and of the cover 5 with the guide 7 on the other hand. The only assembly step in this one-piece molding is that both of the sides 44, 45 of the frame of the base member 1 are pressed together as shown in the direction of both of the arrows that lie on the opposite side. The bridges 41 of fine material are broken by this and the ends of the oscillating shafts 10, 11 slide in the cylindrical bearings that lie opposite to them. At the same time, both of the parts 46, 47 are snapped together at the rear end of the base member 1 and in this manner, the closure is assembled and the oscillation of the cover 5 and the related oscillation of the guide 7 are secured . This closure is not only suitable for the liguids, but also for all types of bulk materials. In all places, where the substances are being packed in paper or plastic bags, such as flour, rice, corn, sugar, salt, etc., the cardboard packaging can now be used and this closure allows to open this package. a simple, clean and safe way and reseal it 44 again after use. In case a tamper evident closure is desirable, then such a closure of the known type can be obtained in such a way that the lid 5 is placed on a tab in the base member 1 with a visible ring retained on a point of rupture for the first time that the closure is closed. After this, it is possible to oscillate the lid 5 only by the rupture at the points of rupture, which leads to a tamper-proof seal, because it can be observed immediately in the closure if it has already been open or not. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention is that which is clear from the present description of the invention.
