Container closure and container comprising the container closure

description

The present invention relates to a container closure and a container comprising this container closure. Furthermore, the invention relates to a container closure work piece.

Container closures are frequently used, in particular, for containers for soft drinks and for drinks containing coffee. Not infrequently, these are temporary container closures made of plastic, which are optionally equipped with a drinking opening, which should prevent the liquid spills over the edge during transport and is lost. Also, the contamination of the drinks in the container or their rapid cooling should be prevented. In addition, there are container closures that are firmly connected to the container. In these cases, a drinking opening must be provided in the container closure. For temporary as well as for permanent container closures in addition to cap-like closures and rosette-like closures are known. The rosette-type locking systems are usually foldable lid constructions in which the folding sections engage in a rosette-like folded manner. Exemplary WO 2005/042359 AI, EP 143 138 AI, GB 1 408 714, US 2,160,488, DE 297 14 486 Ul, DE 195 44 1 16 A I, DE 80 15 375 Ul and GB 416,008 are mentioned in this regard. In order to provide the possibility for the unimpeded passage of a current straw in such rosette-like lid closures, it is proposed in US 4,712,725, adjacent to the lid edge a Durchtri ttsöffnung or provide an inlet option for a straw.

In order to create the passageway for a straw in the center of a rosette-like Deckelverschi usses, WO 01/26980 AI initiates the expert to provide suitable bulges at the outer end of the overlapping folding sections, which in the folded and a cup-closing state a receiving hole for one Yield straw. In addition to the aforementioned central passage for a straw WO 01/26980 AI proposes the simultaneous presence of a perforated breakthrough hole on the edge of the rosette-like folded cover.

The lid closure systems known from the prior art do not yet allow optimal access for straws. Frequently, the diameter of the available straws is not optimally adapted to the size of a passage opening, so that the straw either can not be inserted into the drinking cup without first removing the lid closure, or the diameter of the straw is too small. as a result, liquid can escape easily and in large quantities through the remaining gap should the container tip over. Also, in the latter case, especially in the case of carbonated drinks, the straw is moved upwards unhindered by the buoyancy, which can lead to a very unstable overall system.

The present invention therefore an object of the invention to provide a closure for particular drinking cups available, which is no longer subject to the disadvantages of the prior art and in particular allows a safe and durable closing with simultaneous optimized access for a straw. In particular, the invention was based on the object, reliably and permanently, even during consumption, to protect against contamination in bottled drinks.

Accordingly, a container closure has been found with a circumferential edge which encloses an opening surface, and at least two, in particular at least three, each extending from the peripheral edge shutter blades having an end portion and with opposite, extending from the edge towards the end portion first and second Side boundaries and one of these first and second side boundaries respectively connecting the edge boundary of the end portion, wherein the shutter blades are arranged in pairs adjacent to each other and circumferentially on the edge or present and which are hinged in the direction of the opening surface, wherein folded in the opening surface and the opening surface occluding state respectively adjacent shutter blades in the region of their respective adjacent first and second side boundaries at least partially overlap under closure of the opening surface, wherein the end portions of the shutter at least partially overlap and / or intermesh, at least two, in particular Each shutter blades have at least one, preferably at least two, extending from the first and / or second side boundary and / or the edge boundary of the end portion lines of weakness.

The object on which the invention is based is furthermore achieved by a joint closure with a circumferential edge which encloses an opening surface, and at least two, in particular at least three closure lamellae extending in each case from the peripheral edge, having an end portion and with extending from the edge in the direction of the end portion of the first and second side boundaries and one of these first and second side boundaries respectively connecting edge boundary of the end portion, wherein the shutter blades are arranged in pairs adjacent to each other and circumferentially on the edge or are present and which are hinged in the direction of the opening surface, wherein in the state folded on the opening surface and closing the opening surface, in each case adjacent shutter blades in the region of their respectively adjacent first and second side boundaries at least in sections under closure of the opening surface overlap, wherein the end portions of the shutter blades overlap at least in pairs at least in parts and / or interlock, wherein a straw extends from the peripheral edge, in particular is integrally connected to the peripheral edge. Preferably, it is also provided here that at least two, in particular all shutter blades each have at least one, preferably at least two, extending from the first and / or second side boundary and / or from the edge boundary of the end portion lines of weakness.

The closure lamellae of the container closure according to the invention preferably form a rosette closure. The closure lamellae of the container closure according to the invention are dimensioned in an expedient embodiment in such a way that adjacent lamellae overlap on the opening surface and close this opening surface at least partially overlapping laterally and that the end portions of the closure lamellae overlap at least in sections, at least in pairs. Accordingly, the closure lamellae preferably have a radial extent which, in particular, is slightly larger than the radius of the opening area. The at least two, preferably the at least 3, 4, 5, 6, 7 or 8, in particular all Final lamellae are accordingly configured in an expedient embodiment such that they each overlap laterally adjacent pairs in sections and that their end portions overlap in pairs at least partially overlap when the shutter blades are present in the folded on the opening surface and the opening surface occluding state.

The container closure according to the invention preferably has 5, 6, 7 or 8 closure lamellae. Container closures with 6 closure lamellae are particularly preferred in this case, in particular for use in conventional drinking containers with a capacity in the range of, for example, 150 ml to 500 ml. The number of closure lamellae to be used can also be above 8 closure lamellae, especially in the case of very large opening surfaces to be closed lie, for example at 9, 10, 1 1, 12, 13 or 14 shutter blades. In this way, for each Trinkbehältnisgröße an optimal closure while easy handling can be ensured.

The at least one, in particular the at least two weakening lines extend in a pragmatic embodiment away from the first side boundary of a shutter blade, in particular in the direction of the opposite second side boundary.

The at least two weakening lines, in particular all weakening lines, of at least two or all shutter blades are configured in a preferred embodiment such that they overlap in sections or form an overlap region or at least one overlap or intersection point, if the shutter blades in the folded on the opening surface and the opening surface occlusive state exist. In this way, a reliable passage of a straw as well as a secure hold of the straw can be ensured, the straw is nonetheless easily removable again, in such a way that the container closure the entire opening area safely closes again.

Such container closures according to the invention are also preferred in which at least two lines of weakness, in particular all lines of weakness, of at least two or all closure lamellae, when the closure lamellae are in the state folded on the opening surface and closing the opening surface, have a substantially congruent starting point. Here, for example, in a particularly expedient embodiment also be provided that the starting point is present in the center of the opening area. Furthermore, it can be provided that two or more weakening lines originate from the common, in particular central, starting point. These lines of weakness may be the same or different lengths, but are preferably substantially the same length. Also, such embodiments are preferred in which weakening lines of unterschiedl i chen shutter blades, for example, adjacent shutter blades present congruent or over congruent sections yielded when the shutter blades closes the opening surface and in particular also interlock in a rosette.

Furthermore, such container closures are also preferred in which the first side boundary of a closure lamella and the second side boundary of an adjacent closure lamella have an essentially common starting point in the region of the peripheral edge. In this way it can also be ensured, inter alia, that in the state folded onto the opening surface, the closure lamellae form a substantially liquid-tight seal.

In this case, such closure lamellae of the container closures according to the invention have proved to be particularly advantageous, in which the first side boundary of a closure lamella, in particular substantially each closure lamella, forms an acute angle with the portion of the edge into which this closure lamella, opposite its end portion, merges or adjoins , preferably an angle in the range of 30 to 80 ° and more preferably in the range of 50 to 70 °. Alternatively, and in particular in addition, it may be provided that the second side boundary of this shutter blade, in particular each shutter blade, with the portion of the edge into which this shutter blade opposite the end portion passes or adjoins, an angle in the range of 50 to 1 10 °, preferably in Range of 80 to 100 ° and more preferably of about 90 °. The determination of this angle succeeds most simply and reliably when the shutter blades are unfolded on the edge and the edge is not designed as a peripheral edge, but is rolled out in a plane, i. at the container closure workpiece.

For many applications, it has proven to be very useful to limit the starting points of the weakening lines to certain areas of the closing lamellae. So can in In a preferred embodiment, the at least one line of weakness takes its starting point in the region of the first or second side boundary or in the transition from the first or second side boundary to the edge boundary of the end section. It is particularly advantageous if at least two shutter blades, in particular all shutter blades, the container closures according to the invention over at least two, in particular two or three, weakening lines (also called "first line of weakness", "second line of weakness" and "third line of weakness") have a It can preferably be provided that the common starting point of the at least two or three weakening lines on or in the region of the first side boundary, the second side boundary, the edge boundary of the end portion in the transition from the first side boundary to the edge boundary of the end portion or in the transition from the second side boundary to the edge boundary of the end section, in particular in the transition from the first Seitenbegren- z.ung to the edge boundary of the end portion.

The weakening lines may be formed as slots in one embodiment. Furthermore, suitable weakening lines can represent punching or perforation lines in the material of the container closure, in which the latter only has a low mechanical strength and readily yields when a straw is subjected to force and forms a slit, although they are not yet formed as slits. The formation of the weakening lines in the form of slots is preferred. The weakening lines generally have a length in the range of 1 to 20 mm, preferably in the range of 2 to 10 mm and particularly preferably in the range of 3 to 8 mm.

So that shutter blades are particularly easy to fold in the direction of the opening surface, a folding edge can be provided in the region of a portion of the peripheral edge.

The container closure according to the invention can be made of one material or of several different materials. The container closure, in particular the container closure and the straw, is preferably made of a uniform material. Materials for the container closure according to the invention include paper, cardboard and plastic. For many applications, it has proved to be quite sufficient to resort to paper or cardboard, these materials may be formed in one or more layers. Multilayer structures also include those materials in which a paper or paperboard layer is laminated on one or both sides with a film or has been impregnated on one or both sides. The container closures according to the invention are preferably formed essentially in one piece.

In an expedient embodiment, the end sections of the container closures according to the invention have a rounded outline shape and, in particular, have a substantially semicircular configuration.

For many applications, it has proved to be advantageous that the inventive closure closure further comprises an adjoining the peripheral edge skirt, which is designed and designed to connect the container closure with the opening edge of a container. Alternatively, it can also be provided that this apron adjoining the peripheral edge has an extension which makes it possible to form the wall of the container. In this case, only the bottom of the container would have to be connected to this wall, in order to arrive at a fully functional container, which is equipped with the container closure according to the invention.

Particularly preferred container closures according to the invention are characterized in that they further have between the first side boundary of a first shutter blade and the second side boundary of an adjacent, second shutter blade and optionally between the end portions of these adjacent shutter blades a cover portion having an extending between these adjacent shutter blades end edge. In this case, it is particularly preferred if there is a cover section between adjacent shutter blades. In this way, a container closure according to the invention is obtained, which has no opening from the edge to the end section or the end edge of the cover sections and thus permits a particularly liquid-tight seal. The end edge of the cover sections preferably does not extend to the outer edge boundary of the end sections.

Preference is given to such container closures according to the invention, in which at least one line of weakness, in particular the first line of weakness, from the mouth point at which the end edge opens into the shutter blade, its output.

Particularly good and reliable results with regard to the safe handling of straws and, in connection with the tightness of a drinking container closed or provided with the container closure according to the invention, also result from the fact that the first line of weakness, which originates at the point of emergence, is substantially collinear with the terminal edge and / or is aligned substantially parallel to the adjacent portion of the peripheral edge. In this way, it is particularly reliable that the weakening lines of different shutter blades in the closed state partially or in particular completely coincide with each other. This is especially true even if a line of weakness, in particular, the second line of weakness, from the mouth point at which the terminal edge opens into the shutter blade, its output and is in relation to the first line of weakness beyond the edge boundary of the end portion and forms an angle with the first line of weakness. The included between these lines of weakness are in particular in the range of 30 to 80 °, preferably in the range of 40 to 70 ° and particularly preferably at about 60 °, in particular even if the container closure or the underlying container closure workpiece has six shutter blades ,

Such container closures according to the invention have proven to be particularly expedient, which further comprise a third line of weakness, which starts at the mouth point and which extends in sections or along the side boundary or fold line.

It can preferably be provided that the second weakening line of the first, in particular overhead, shutter blade is substantially congruent with the first side boundary. Alternatively and in particular in addition, the second weakening line of the first, in particular upper, shutter blades may be substantially congruent with the third weakening line of the adjacent second shutter blade partially overlapping with the first shutter blade, in which case the second shutter blade is particularly direct partially present under the first shutter blade. Alternatively, it is also possible that the first shutter blade is present under the adjacent, overlying second shutter blade. Here, too, with the container closures according to the invention, substantially overlapping overlaps of first and second or second and third weakening lines occur in the closed state. Preference is given to those embodiments of sealed container closures according to the invention in which the partially overlapping end sections of the closure lamellae are present on the upper side, ie can be seen directly in generic use.

In the illustrated embodiment, the container closure work piece 100 comprises six closure lamellae 6 which extend away from an edge line 102 which forms the peripheral edge 2 in a container closure formed therefrom or in a container according to the invention formed therefrom (see also FIG. 2 a) - c)). , For ease of folding the shutter blades 6, the fold line 102 is formed in the illustrated embodiment as a fold. The shutter blades 6 are each formed by a portion of the edge line 102, opposite the first and second side edges 8, 10, also called side boundaries, and an end portion 12 connecting these side edges with a substantially semicircular rank limit 15. While the first side boundary 8 is pointed Angle forms with the adjacent to the shutter blades edge portion 102, the second side boundary 10 for this purpose arranged substantially at right angles. The shutter blades 6 are thus tapered in the direction of the end portion 12. In the illustrated embodiment, no distance is left between adjacent shutter blades 6. Rather, the first side boundary 8 of a first shutter blade 6 and the second side boundary 10 of an adjacent, second shutter blade 6 in the region of the edge line 102 have a common Starting point 17. Between adjacent shutter blades 6, a cover portion 26 is present. This extends between the first side boundary 8 of a first shutter blade and the second side boundary 10 of the adjacent shutter blade 6 and is limited in the direction of the end portions 12 by the end edge 28. In the illustrated embodiment, the end edges 28 of the cover portions 26 are substantially rectilinear or parallel to the edge line 102.

The container closure piece 100 also has a container closure skirt 104. In the illustrated embodiment, this is formed as a wall surface for the container to be formed from the workpiece. This skirt or wall surface 104 extends opposite to the edge line 102 to a lower edge 106. Laterally, the container closure piece 102 and the wall 104 is bounded by side edges 108 and 110. In the preferred embodiment of a container closure piece 100 according to the invention shown in FIG. 1, the side edge 108 of the wall 104 extends in the sense of an extension into the second side boundary 10 of the outer closure lamella 6. This second side boundary 10 and the first side edge 108 are co-linear.

In the container closure work piece 100 shown in FIG. 1, shutter blades 6 and cover sections 26 are arranged alternately in such a way that this sequence begins in the region of the first side edge 108 with a first shutter blade 6 and ends adjacent to the second side edge 1 10 with a cover section 26. In the illustrated embodiment is in the region of the second side edge 1 10 and in the region of the cover section 26 adjacent thereto, a coupling area 1 12 before. This extends from the lower edge 106 of the skirt 104 to the final edge 28 of the outer cover portion 26. This coupling area 12 1 creates a connecting or overlapping strip, which by means of suitable adhesive with a corresponding surface along the first side edge 108th the wall 104 and the second side boundary 10 of the outer shutter blade 6 can be connected to form a container body.

The container closure workpiece 100 according to the invention can, as shown in FIG. 1, be formed in one piece. For this purpose, recourse may be had to paper or cardboard materials of suitable thickness. In order that a rosette-type closure can be accomplished without problems by means of the shutter blades 6, in a preferred embodiment the first and second side boundaries 8, 10 are designed as folding lines. This can for example be accomplished via a fold or a perforation. In a preferred embodiment, the first S eitenbegrenzungen 8 are in the form of a perforation, while the second side boundaries 10 are formed as a fold.

Moreover, in the container closure piece 100 of the invention shown in Figure 1, each shutter blade is provided with two lines of weakness 14 and 14 'in the form of slots. These weakening lines 14 and 14 ', also called first and second weakening line, have a common starting point 20, also called the mouth point. In the illustrated embodiment, this starting point 20 is present in the transition from the first side boundary 8 to the edge boundary 15 of the end section 12. In addition, the first weakening line 14 is formed colinearly to the end edge 28 and thus is substantially parallel to the corresponding portion of the edge line 102. The first and second lines of weakness 14 and 14 'in the illustrated embodiment enclose an angle of about 60 °. The weakening lines 14, 14 'represent in the embodiment according to FIG. 1 slots or cuts. These preferably result in a substantially identical longitudinal extension. A preferred angle, which is enclosed between the second line of weakness 14 'and the first side boundary 8, is about 60 °, as can also be seen in the embodiment shown in FIG. All weakening lines are preferably slots, but may also be formed, for example, in the form of perforation line sections.

Also shown in Figure 1 is a container closure piece 100 having third lines of weakness 14 ", these third lines of weakness 14" leaving substantially the same starting point as the first and second lines of weakness 14 and 14 '. For the purpose of better illustration, in FIG. 1, the third weakening lines 14 "are not directly depicted on the first side boundary, but slightly offset therefrom. FIG. 2c) shows a perspective side view of a container 200 according to the invention, formed from the container closure workpiece 100, as shown in FIG. In the region of the lower edge 106 of the container closure work a container bottom 202 has been incorporated. The shutter blades 6 as well as the cover portions 26, which are present between adjacent shutter blades, are in unfolded form. The edge line 102 of the container closure workpiece 100 forms the peripheral edge 2 in the container 200. The container 200 is accordingly formed by the container closure 1 according to the invention and the container bottom 202. In the embodiment of a container according to the invention shown in FIG. 2, the container wall 204 is part of the one-piece container closure 1. Of course, such embodiments are possible in which the container closure below the container circumferential edge 2 only partially extends and then forms a container according to the invention with a separate, circumferential Wandungsbahn, in the lower edge of a container bottom is incorporated.

By folding the shutter blades 6 successively in the direction of the opening surface, for example, a rosette-like overlap is formed, which ultimately leads to a closed container. FIGS. 3 to 5 show different stages of the closing process.

When on the opening surface flaps of the shutter blades 6 adjacent cover portions 26 come on the shutter blade 6 to the plant. These cover sections 26 are covered in the closed state by the adjoining closure lamella. Consequently, there is a partial overlap of adjacent shutter blades 6.

For ease of illustration of the embodiment of the inventive container 200 is a plan view of the unclosed container 200 according to 2a) in Figure 2b) reproduced. The circular peripheral edge 208 reflects the shape and dimensions of the cup bottom 202. It can also be seen that the wall which is essentially circular in cross-section merges into a hexagonal basic shape in the region of the peripheral edge 2 due to the use of six shutter blades 6. In particular, FIGS. 2 a) and 2 c) take the first, second and third weakening lines 14, 14 'and 14 ".

In the closed state, these weakening lines have a common starting point 210 which lies in the center of the closed opening area. The angle that is taken between adjacent lines of weakness is here at about 60 °.

When the closure lamellae 6 are folded together, the first weakening line 14 of a closure lamella present below an adjacent closure lamella 6 approximately coincides with the second weakening line 14 'of this closure lamella which comes to rest on the upper side. Accordingly, it happens that the second weakening line 14 'of this underlying shutter blade is approximately in coincidence with the third weakening line 14 "of the closing shutter adjoining the upper end. second and third line of weakness substantially congruent one above the other.

As can be seen, for example, from FIG. 5b), the shutter blades completely close the opening surface of the container 200. Slit lines in the form of slits do not allow the automatic passage of liquid should the package 200 be tilted to the side or fall over. On the other hand, the construction according to the invention allows safe and reliable passage of a straw in the area of the overlapping skin areas. If the weakening lines are not already slots, the weakening lines are correspondingly torn open by the straw imports and transferred to weakening slots. Due to the intrinsic stiffness of the material, for example cardboard material, the triangular segments present between the individual weakening lines abut against the outer side of the straw and hold it firmly. After pulling out of the straw can be ensured with a suitable choice of material that the flexibility of this material causes the opening area is completely closed again, as shown for example in Figure 5b). The erfindungsgenmäßen container 200 are very resource efficient. The use of plastic lids can be completely dispensed with. Moreover, it is readily possible to produce the material of the container closure according to the invention or of the container according to the invention from renewable raw materials.

In the figures 6 to 14 further embodiments are explained, which now comprise a straw or drinking straw or a straw forming section or drinking straw forming section. In order to avoid unnecessary repetition, with regard to the aspects which do not concern the straw, the straw-making section or an access for the straw, reference is made to the above statements, which can be transferred analogously. The first, second and third weakening lines 14, 14 ', 14 "are each also shown, but are not necessarily provided in the respective embodiments of FIGS 6 to 14 and are only optionally conceivable first, second and third lines of weakness 14, 14 ', 14 "subject of this disclosure.

FIG. 6 shows another container closure piece 100 according to the invention for forming a container closure with a straw. The skirt wall surface 104 extends opposite the edge line 102 to a lower edge 106 and is connected, in particular in one piece, to a straw forming section 600 along a connecting region 602. The straw forming section 600 is designed and arranged to form a straw integrated into the container closure or into the container. The straw forming section 600 includes a chamfered lower end 608 for fluid intake. Further, a recess 612 is provided in one of the shutter blades 6 to pass a straw.

FIG. 7 shows an embodiment analogous to FIG. 6, wherein the lower end 610 of the straw forming section 600 is not chamfered, but straight. As a result, the liquid supply can be controlled even better, and in particular liquid in the vicinity of the bottom of the container can be removed particularly well if there is only a small amount of liquid left in a container formed from the container closure workpiece. Furthermore, marginal additional weakening lines 614 are formed in one of the shutter blades 6 to facilitate the closing of the shutter blades despite the presence of a straw. With regard to the remaining reference numerals, reference is made to FIGS. 1 and 7. Figure 8 shows a container 200 similar to Figure 5 c), in which case the integrated straw 604 is also reproduced. It comprises an upper end with a drinking opening 606. The container 200 has been formed with the container closure piece 100 of FIG.

FIG. 9 shows a further container closure piece 100 according to the invention with a straw-forming section 600, which is connected to the coupling area 12, in particular in one piece. The straw forming portion 600 preferably terminates at or spaced from the edge line 102, in particular spaced and closer to the bottom edge 106 than the edge line 102. Additionally, in this embodiment, an access perforation 615 is provided which bounds a straw access 617. Through the straw access 617, the drinking opening 606 (not yet finished) is accessible.

FIG. 10 differs from FIG. 9 in that the straw forming section 600 extends further beyond the height of the edge line 102, but at the level of the edge line 102 or spaced therefrom, in particular spaced and closer to the lower edge 106 than the edge line 102, is a straw perforation 605 through which the straw in the area of the straw shark can be severed. If someone wants to drink it opens the straw access 617 in the final container and cuts the straw to create a drinking opening in the area of the straw perforation 605.

FIG. 11 shows a possible embodiment of a container with access perforation 615 and straw access 617. The connecting lamellae are displaced with respect to FIGS. 9 and 10 in this embodiment, which is entirely possible according to the invention.

FIG. 2 shows another container closure piece 100 according to the invention with a straw forming section 600, which is connected to the coupling area 112, in particular in one piece. The straw forming section 600 extends beyond the edge line 102. First and second access perforations 601 and 603 allow a portion of the straw to be exposed in the final container.

FIG. 13 shows a further container closure piece 100 according to the invention with a straw forming section 600, which is connected to the coupling area 112, in particular in one piece. The coupling area 1 12 is located on the opposite side compared to FIG. 12. First and second access perforations 601 and 603 allow a straw to be exposed in the final container by severing a straw access 626. The straw access may also include a third access perforation 607 in this embodiment.

Figure 14 shows a possible embodiment of a container with straw access 626 in a shutter blade. Such a configuration can preferably be obtained with the container closure workpiece of FIG. 13,

FIG. 15 is a schematic diagram to show how, upon severing access perforations 601 and 603, straw access 626 is uncovered along with integrated straw 604, particularly where straw access 626 is a weakened zone associated with the integrated straw.
