    Manufacturing steps for producing such packaging closures of prior art.
    A disadvantage of such prior art packaging closures is that they require an extensive amount of material. A screw cork requires considerable rigidity in both the cork and the neck, which entails extensive material consumption.
    SUMMARY OF THE INVENTION An object of the invention is to avoid the above-mentioned disadvantages and problems of the prior art. The package closure according to the invention entails extensive material savings and a simplified manufacturing procedure where the entire packaging closure can be manufactured in one step in a single tool without mutual retrofitting of the various parts of the package closure while the package closure according to the invention results in a tight, tamper-proof and resealable packaging closure.
    The present invention relates to a package closure comprising a neck provided with an opening and a lid for closing the opening, the neck comprising a connecting portion designed for connection to a package and a sealing portion projecting radially inwardly from the connecting portion for co-operation with the lid during formation of a seal therebetween, characterized in that the lid, before opening thereof, is connected to the sealing portion via an instruction, the lid being separable from at least a part of the sealing portion by tearing along the instruction, and that the lid is provided with one from an inside at the lid projecting sealing part for co-operation with the sealing portion of the neck, so that the packaging closure is resealable.
    The instruction arranged between the lid and the sealing portion in combination with the sealing part of the lid cooperating with the sealing portion results in a considerable saving of material as the packaging closure can be achieved without threaded cork or the like. At the same time, the packaging closure can be produced in a tool in a single manufacturing step, which results in a simple and cost-effective production. The instructions entail a gas-tight packaging closure and the sealing portion in combination with the sealing part of the lid enables a tight and resealable packaging closure.
    The packaging closure is made of a flexible resilient plastic material, where the flexibility can be set, for example, by determining the material thickness. The sealing part and the sealing portion can form a seal through resilient cooperation due to their inherent flexibility.
    An inside of the lid may be provided with a flexible projection for co-operation with a tool core in a device pre-manufacturing the package closure, so that the lid is connected to the tool core during manufacture thereof. Through the projection, the cover can be temporarily connected to and held at the tool core. At the same time, the sealing portion can be flexibly designed and bendable in relation to the connecting portion, so that the connecting portion is displaceable relative to the lid during bending of the sealing portion and folding along the instruction when the lid is connected to the tool core via the projection. The projection may be stiffer than the sealing portion. In this way, the production of the lid and neck in one piece is facilitated, ie. in the form of an integrated part, in order to achieve a package closure provided with a tear-off and resealable package. The sealing portion and the sealing part can cooperate through a snap-lock function to facilitate resealing of the lid.
    The lid can be connected to the neck via a hinge portion, so that the lid is arranged rotatably around the hinge portion, and wherein a portion of the lid and the neck cooperate via a snap-lock function, so that the lid is connectable to the neck in its open position. In this way, a hinged lid can be kept in its open position when emptying the package, so that the lid does not inadvertently prevent emptying or is in the way.
    The invention also relates to a device for producing a package closure with a neck and a lid, comprising a movably arranged first jaw, a movably arranged second jaw and a tool core cooperating with the jaws to form a mold for the package closure, and an ejector for ejecting the manufactured packaging closure, characterized in that the tool core comprises an outer tool core and an inner tool core movably arranged relative to the outer tool core, that the outer tool core is designed to cooperation with the jaws form a connecting portion and a sealing portion of the neck and an instruction between the neck and the lid, and that the inner tool core comprises a portion for forming and cooperating with a projection of the inside of the lid, so that the neck by means of the ejector is displaceable relative to the lid during bending of the sealing portion and folding along the instructions when l the yoke is connected to the inner tool core via the projection.
    The invention also relates to a method for producing a packaging closure with a neck and a lid, characterized by the steps of forming a connecting portion and a sealing portion of the neck by means of movably arranged jaws and an outer tool core and an instruction between the sealing portion and the lid. , by means of an inner tool core, form a flexible projection of the inside of the lid made for co-operation with the inner tool core, remove the jaws from the shaped package closure, displace the package closure and the inner tool core relative to the outer tool core to at least partially release the gasket closure from the outer tool core, by means of the inner tool core hold the lid through the projection formed on the inside of the lid and at the same time, by means of an ejector, displace the connecting portion of the neck relative to the lid during bending of the sealing portion and folding along the instruction, hrs with the aid of the ejector, the displacement of the packaging closure in relation to the inner tool core, so that the projection is released from the inner tool core due to its flexibility.

    THE INVENTION With reference to Fig. 1, a packaging closure 10 and a part of a device for the manufacture of the packaging closure 10 are schematically illustrated. The packaging closure 10 is made of a flexible material, such as a suitable plastic material. For example, the packaging closure 10 is formed of a suitable thermoplastic, such as polyethylene. The device comprises a movably arranged first jaw 11, a movably arranged second jaw 12, an abutment plate 13 and a tool core 14 cooperating with the jaws 11, 12 and the abutment 13 to form a mold for receiving a quantity of plastic material for the production of the packaging closure 10. The device further comprises a movably arranged ejector 15 for ejecting the manufactured packaging closure 10, which is described in more detail below. The device is designed as a molding tool for molding plastic material. For example, the device is designed for molding plastic material, whereby the jaws 11, 12 and / or the tool core 14 can be heatable and / or coolable in a conventional manner. The jaws 11, 12 and the tool core 14 are made with a special design for producing the mold for manufacturing the packaging closure 10 in accordance with the invention, which design is apparent from the description of the special features of the packaging closure 10 below.
    The tool core 14 comprises an outer tool core 16 and an inner tool core 17 arranged in relation to the outer tool core 16.
    Thus, the inner tool core 17 is displaceable in the axial direction relative to the inner tool core 16. For example, the outer tool core 17 is fixedly arranged.
    In Fig. 1, the device is shown in a position where the jaws 11, 12 cooperate with the abutment 13 and the tool core 14 to form the mold for forming the packaging closure 10 and where a packaging closure 10 is located in the mold, i.e. in abutment with the jaws 11, 12, the abutment 13 and the tool core 14.
    Referring to Fig. 2, the device is shown in a position for ejecting a manufactured packaging closure 10. In the position shown in Fig. 2, the jaws 11, 12 and the anvil 13 are released from the packaging closure 10.
    Thus, the jaws 11, 12 are movably arranged in a direction substantially transverse to a center axis X of the package closure 10, which direction is shown by means of the arrow A Fig. 2, between the position shown in Fig. 1 and the position shown in Fig. 2. Furthermore, the abutment 13 is movably arranged in a direction along the center axis X of the packaging closure, as shown by means of the arrow B in Fig. 2, between the position shown in Fig. 1 and the position shown in Fig. 2. When the jaws 11, 12 and the abutment 13 are released from the packaging closure 10, the packaging closure 10 can be pushed forward axially by means of the ejector 15 in a direction along the center axis X of the packaging closure, as shown by the arrow C in Fig. 2.
    Referring to Fig. 3, the package closure and part of the device are shown in more detail. In Fig. 3, an upper portion of the outer tool core 16 has been removed to more clearly show the design of the package closure 10.
    In the embodiment shown, the package closure 10 is substantially cylindrical with a circular cross-section. Alternatively, the cross-section of the package closure 10 is elliptical, triangular, rectangular or otherwise shaped, with or without rounded corners. The packaging closure 10 comprises a neck 18 provided with an opening and a lid 19 extending across the opening for closure thereof. For example, the lid 19 extends substantially radially.
    The neck 18 comprises a connecting portion 20 designed for connection to a package and a sealing portion 21 projecting at an angle from the connecting portion 20. The connecting portion 20 extends, for example, substantially axially.
    In the embodiment shown, the connecting portion 20 is formed with an angular portion 22 arranged at an angle to the connecting portion 20 in order to facilitate connection with a package. For example, the angular portion 22 projects substantially radially relative to the connecting portion 20. The sealing portion 21 is made thinner than the connecting portion 20 and projects inwardly relative to the connecting portion 20. The sealing portion 21 terminates with a tapered portion to form an instruction 23. in connection with the lid 19. The sealing portion 21 is thus connected at one end to the lid 19 when the lid 19 has not been opened and the instruction 23 is intact. Thus, the outer tool core 16 is designed to form, in cooperation with the jaws 11, 12, the connecting portion 20 and the sealing portion 21 of the neck 18 and the guide 23 between the neck 18 and the cover 19.
    The cover 19 is provided with a sealing part 24 projecting from an inside of the cover 19 and a projection 25 projecting from the inside of the cover 19.
    For example, the sealing member 24 and the projection 25 extend substantially axially and parallel to each other. The sealing part 24 is arranged between a peripheral edge of the lid 19 and the projection 25, the projection 25 being arranged between the center axis X and the sealing part 24 and thus more centrally than the sealing part 24. The sealing part 24 is further connected to the sealing portion 21 of the neck 18 via the guide 23 when the instruction 23 is unbroken. The projection 25 is flexibly designed and arranged for co-operation with the inner tool core 17, so that the lid 19 is connected to the inner tool core 17 via the projection 25 during manufacture of the packaging closure 10.
    With reference to Figs. 4-8, a part of the production of the packaging closure 10 according to an embodiment of the invention is schematically shown. The outer tool core 16 is removed from Figs. 4-8. Figs. 4-8 schematically show an ejection method in which a pre-cast packaging closure 10 is ejected from the device thereof during simultaneous completion thereof. In Fig. 4, the ejector 15 and the inner tool core 17 are shown in a position for casting the package closure 10.
    As can be seen more clearly from Fig. 4, the sealing portion 21 of the neck 18 is provided with a locking member 26 for co-operation with a locking element 27 of the sealing part 24 of the lid 19 to form a snap-lock function, which is described in more detail below. In the embodiment shown, the locking member 26 is designed in the form of a bulge, the locking element 27 being designed in the form of a depression. For example, the depression is arranged substantially radially inwards in the direction of the projection 25 and the center axis X. Alternatively, the locking member 26 is designed in the form of a depression, the locking element 27 being formed in the form of a bulge.
    The snap-lock function is achieved by the inherent flexibility of the packaging closure 10 and, for example, the flexibility of the sealing portion 21. The sealing portion 21 is, for example, angled obliquely inwards relative to the connecting portion 20.
    The packaging closure 10 according to the invention is cast, for example, in one piece, the lid 19 and the neck 18 being an integral part. The jaws 11, 12 and the tool core 14 form a continuous shape to form the neck 18 and the lid 19 in a continuous piece.
    After casting the package closure 10, when the material in the package closure 10 is still soft and not yet completely solidified or crystallized, both the ejector 15 and the inner tool core 17 are moved axially forward, as shown by the arrows D and E in Figs. 4, while carrying the package closure 10 in the same direction, so that the lid 19, the sealing portion 21 and at least a part of the connecting portion 20 are released from the outer tool core 16. Thus, the inner tool core 17 and the ejector 15 are displaceable in axial direction relative to the outer tool core 16. Alternatively, the outer tool core 16 is pulled back relative to the ejector 15, the inner tool core 17 and the package closure 10.
    Thereafter, the ejector 15 is displaced axially forward, as shown by the arrow F in Fig. 5, relative to the inner tool core 17 while the inner tool core 17 cooperates with the projection 25 to retain the cover 19, so that the neck 18 by means of the ejector 15 is displaced relative to the cover 19 during bending of the sealing portion 21 and folding along the guide 23. Thus, the ejector 15 is displaceable in the axial direction relative to the inner tool core 17. The ejector 15 is displaced relative to the cover 19 while simultaneously negative folding of the sealing portion 21, so that the sealing portion 21 is folded inwards towards the center axis X and in the direction of a bottom of the neck 18. Thus the sealing portion 21 is bent relative to the connecting portion 20 of the neck 18 at the same time as the sealing portion 21 is folded along the sealing portion 24. 23 in a negative fold-in of the sealing portion 21, so that the sealing portion 21 and the sealing part 24 are folded in. to the neck 18. In order to temporarily hold the cover 19 temporarily, the inner tool core 17 in the embodiment shown is provided with a recess 28 for receiving the projection 25 or a radially inwardly projecting flange 29 of The projection 25 is thus stiffer than the sealing portion 21 and the guide 23, the sealing portion 21 and the guide 23 being folded upon axial displacement of the ejector 15 instead of the projection 25. The connecting portion 20 is pressed up against the cover 19 at the same time as the sealing portion 21 is folded inwards and downwards , so that the sealing portion 21 is brought together with the sealing portion 24, as shown in Fig. 6. Thus, the sealing portion 21 is folded to a position where it extends substantially axially downward or obliquely downward and inwardly to cooperate with the sealing portion 24 while the guide 23 connects the sealing portion 21. and the sealing part 24. The sealing portion 21 is folded negatively inwards, so that the sealing portion 21 and the sealing part 24 are arranged between the neck 18 and the center. the trunk axis X, i.e. inside the neck 18. For example, the sealing portion 21 is folded to a position where the locking member 26 cooperates with the locking element 27. Thereafter, the ejector 15 is moved further axially forward while bringing the package closure in the same direction, as shown by the arrow G in Fig. 7, so that the protrusion 25, due to its inherent flexibility, is released from the inner tool core 17 and can leave the device for manufacturing the package closure 10. For example, the protrusion 25 returns to its original position due to its flexibility, as shown in Fig. 8.
    The ejection of the package closure 10 is performed, for example, within one or a few seconds after its casting, the temperature of the material in the package closure 10 being above room temperature and, for example, above 40 ° C or about 60 ° C, so that the material is semi-liquid during the ejection.
    For example, the lid 19 includes an axially extending peripheral portion 30 outside the sealing portion 24 for abutment with an axially extending connecting portion 31, the connecting portion 31 sealing portion 21 connecting to the connecting portion 20 when the package closure 10 is made and the lid 19 is closed.
    Referring to Fig. 9, the package closure 10 according to an embodiment of the invention is shown where the package closure 10 is connected to a package 32 and is unopened, the instruction 23 being unbroken.
    When opening the lid 19, the sealing portion 21 will be folded slightly upwards, as shown in Fig. 9 and Fig. 10, after which the guide 23 is broken, as shown in Fig. 10, until the lid 19 can be opened, as shown in Fig. 11. For example, the lid 19 is connected to the neck 18 via a hinge portion to form a hinge function, so that the lid 19 can be folded up when opened and folded down when closed again. Alternatively, the lid 19 can be completely released from the neck 18.
    Fig. 12 shows the lid 19 in the open position where the lid 19 is folded up or removed from the neck 18. When the lid 19 is in the open position, the sealing portion 21 projects obliquely downwards and inwards, so that the sealing portion 21 is arranged inside the neck 18 and a free end of the sealing portion 21 is directed away from the lid 19 and towards an opening of the package for co-operation with the package closure 10. When the lid 19 is in the open position the sealing portion 21 is released from the lid 19 and the sealing part 24 and is then not affected by the lid 19 or the sealing part 24. The sealing portion 21 is negatively folded and is angled obliquely inwards towards the center axis X, so that the free end of the sealing portion 21 is arranged at a distance S from the inside of the connecting portion 20 of the neck 18 when the sealing portion 21 is unaffected by the sealing portion 24. More specifically, an inner side of the sealing portion 21 facing the center axis X is arranged at the distance S from the inside of the connecting portion 20 of the neck 18. angle between the sealing portion 21 and the connecting portion 20 of the neck 18 less than 90 °, for example 5 ° -45 °, 10 ° -30 ° and for example about 15 °.
    In Fig. 13 the lid 19 is shown in the closed position. When closing the lid 19, the sealing part 24 and the sealing portion 21 cooperate to form a snap-lock function, the lid 19 being resealable. For example, the sealing portion 21 is made with a flexibility which allows a certain radial displacement relative to the sealing part 24 when the lid 19 is closed, so that the sealing portion 21 is pressed slightly to the side radially outwards by co-operation with the sealing part 24, so that the sealing portion 21 is pressed against the sealing part 24 to form a seal when the lid 19 is closed. Thus, the sealing portion 21 is pressed radially outwards in the direction away from the center axis X and in the direction of the connecting portion 20 of the neck 18 in cooperation with the sealing part 24, so that the free end of the sealing portion 21 ends at a distance from the connecting portion 20 of the neck 18. 12 is smaller than the distance S. Thus, the sealing portion 21 presses against the sealing part 24 through the inherent flexibility of the material while forming a bias or sealing force in the direction of the sealing part 24. An outer side of the sealing part 24 is, when the lid 19 is closed, arranged at a distance T from the inside of the connecting portion 20 of the neck 18. The distance T is less than the distance S. Thus the length of the sealing portion 21 is greater than the distance T, the length and angle of the sealing portion 21 being coordinated with the distance T between the connecting portion of the neck 18 And the sealing part 24, so that an inner side of the sealing portion 21 abuts against an outer side of the sealing part 24 on such a surface. that the sealing portion 21 is in a clamped position and presses with a sealing force against the sealing part 24 when the lid 19 is in the closed position.
    For example, the sealing portion 21 is pressed to the side when closing the lid 19, so that the locking member 26 and the locking element 27 can engage each other to form a tight snap-lock function. For example, the sealing part 24 presses the sealing portion 21 to the side when resealing, so that the locking member 26 can be accommodated in the locking element 27. Alternatively, the sealing part 24 is made flexible in relation to the sealing portion 21 or both the sealing portion 21 and the sealing part 24 are flexible performed.
    Referring to Fig. 14 and Fig. 15, the package closure 10 according to an embodiment of the invention is shown, where the lid 19 is connected to the neck 18 via a hinge portion 33. In the embodiment shown in Figs. 14 and 15, the lid 19 is provided with a first snap lock portion 34, the neck 18 being provided with a second snap lock portion 35 to form a snap lock function between the lid 19 and the neck 18, so that the lid 19 is releasably connectable to the neck 18 in its open position. Thus, the lid 19 is connectable to the neck 18 via the first and second snap lock portions 34, 35, so that the lid can be kept in its open position when emptying the package. For example, a rear portion of the lid 19 is connected to the neck 18 via the hinge portion 33, the first snap-lock part 34 is arranged in the rear part of the lid 19. For example, the first snap-lock part 34 is designed as an ace extending along the rear portion of the lid 19 and extending substantially parallel to the hinge portion 33. The second hinge portion 35 is designed, for example, as a part radially outwardly extending from the connecting portion 20 of the neck 18 with a depression 36 for receiving the first snap lock part 34. The snap lock function is provided by the first snap lock part 34 and / or the second snap lock part 35. inherent flexibility in a conventional way.
    Referring to Figs. 16 and Fig. 17, the package closure 10 according to an embodiment of the invention is shown, wherein the package closure 10 is provided with a first closure member 37 and a second closure member 38 for cooperating with the first closure member 37 to form an outer closure device for lock the lid 19 in its closed position and prevent unwanted opening of the lid 19. The first fastening part 37 is adjustable from its locked position to an unlocked position. The first fastening part 37 is arranged on the lid 19 and comprises a part 39 projecting radially from the lid 19 and a part 40 projecting axially therefrom, forming a downwardly projecting hook or the like. The axially projecting part 40 is in the embodiment shown provided with a wider and downwardly directed free end 41 while forming a receiving space for at least partially receiving the second buttoning part 38. For example, the axially projecting part 40 is made with grooves 42 or similar to the sealing portion 24 of the lid 19 to provide increased friction against the second button portion 38. The second button portion 38 includes a radially outwardly projecting bulge 43 for cooperating with the axially projecting portion 40 of the first button portion 37 to form a snap lock function.
    The axially projecting part 40 is resiliently made by the nature of the material, so that the axially projecting part 40 can at least partially be forced past the bulge 43 and by the resilient flexibility of the material clamped behind the bulge 43 or the outermost portion of the bulge 43. For example, the grooves 42 are made to abut against the bulge 43 to prevent the bulge 43 from leaving the receiving space and the axially projecting part 40 being released from the bulge 43.
