Description

DESCRIPTION

Closing means for bags, in particular garbage bags

The present invention relates to a closing means for bags, in particular garbage bags, comprising two half-elements, respectively, with a first and a second edges spaced apart in an axial direction and with a wall, which extends in an axial direction. between the first and second edges, and where the semi-elements are nested together by means of hinges and complement each other in the form of a ring in a first position for the formation of an extended configuration of the closure element and in this way are pivotable around the hinges to a second position, in such a way that the half-elements support each other with their first edge, and where closing elements are provided, which lock the half-elements together in the second position.

Such closure elements for bags, in particular garbage bags, are known in the state of the art. A frequent field of application represents traveler's disease, but also other cases of vomiting. In addition, other application chaos for bags are contemplated, in particular garbage bags, in which a safe maintenance of the opening of the bag or of the bag is desired by clamping the same and then a secure closure of the bag is achieved. content, especially garbage.

Such closure means have a first and a second edge, where the first edge is the upper edge in the case of use, which determines the actual opening for a user. If a garbage bag or bag is provided with such a closure means, then the garbage bag or bag in the area of its open end is led through the interior of the closure means and this closure area is placed. the bag or garbage bag on the first edge of the closure means. In this case, the first edge of the closure means is overlapped by the bag or garbage bag from the inside out. In this case, the bag or garbage bag is preferably fixed by deformation in an elastic and / or plastic manner.

In such closing means, the opening of the bag or garbage bag can be safely kept open, whereby contamination of the area of the opening of a bag or garbage bag held in this way can be better avoided. . Prevention of contamination is desirable especially in the case of contents, especially garbage, which must subsequently be closed safely and without contact.

Thus, for example, a closure means is described in the state of the art as in documents US4610039 or US20070031068 or also in practice, in which a closure of the bag is made in such a way that the bag is twisted under the second lower edge of the closure means and the twisted area then engages in a notch in the closure means provided on the second edge. In this configuration it is a drawback that the contaminations, 2 which are in the immediate zone of the closure means, are not safely drawn through such closure of the garbage bag. The evacuation of such a garbage bag can also be considered as unhygienic.

Document WO 2009/021268 A1 describes a closure means according to the preamble of claim 1 and, in particular, a disposable garbage container for use in ambulances, hospitals, but also in travel applications, comprising a bag of trash and a means of closure. In this regard, it is known from the state of the art, on the one hand, to provide a configuration, in which a twisted garbage bag likewise engages in a notch. For the rest, it is described to provide a film hinge in the area of the first edge and a breakable connection in the area of the second edge, so that a folding of the two half-elements directed towards each other and thus an extraction is possible. of the same. Furthermore, it is also already known to configure the closing means in such a way that the two half-elements are placed one on top of the other and are tied together by means of closing elements. Closure means of this type known from the state of the art can often be mishandled, that is to say they are unwieldy. Furthermore, it has been found that the two half-elements can only be folded and closed frequently using both hands. But there are often situations, in which the user or the applicator of a bag configured with such a closure means does not have both hands.

The invention solves this task with the aid of a closing means for bags, in particular garbage bags of the type mentioned at the beginning, wherein in this case it is provided according to the invention that at least one half-element in the area of the first edge at least an inlet pointing in a radial direction inward and / or at least one half-element has, starting from the second edge, at least one recess extending in an axial direction.

In this way, it is achieved that by means of the entrance and / or a notch in the contour made on the respective edge within a continuous development of a half-element, the closure means is configured in an advantageous ergonomically manipulable manner, which it also causes a reduction in the expenditure of force during closing from the first position to the second position.

The inlets pointing in a radial inward direction serve to grip the closure means, on the one hand, when such a closure means is used for a bag, in particular a garbage bag, during use, where the bag, in particular garbage bag, can be retained in the closure means and the fingers can be snapped into the entrances and thus improve retention. Furthermore, these inlets, which can serve as gripping cavities, also serve to facilitate the transfer of the closure means from the first to the second position, since in this way grip points are provided for the fingers of one hand.

Furthermore, preferably, at least two, more preferably at least three and still more preferably four inputs can be provided in a half-element.

In principle, the entrances can have different sizes and numbers according to the desired ergonomic point of view.

The recess extending from the second edge in the axial direction serves in particular to enable the locking means to be gripped from the underside and, in particular, to enable the hand to be accommodated and the hand to be guided in an ergonomic manner during operation. transition from the first to the second position and during the confluence of closure elements, as for example during the insertion of retention projections in corresponding openings. The closing of the two half-elements to each other and the mooring of the two half-elements to each other are clearly facilitated in this way. These recesses serve in particular to enable a bypass after a first grasp and hold of the closing means by fingers in the area of the first edge during use and then a secure transition from the first to the second position and a clamping with the least expense of possible strength. According to the embodiment, the reduction in the height of the wall of the half-element achieved by a recess makes it possible for the closure means to be easily operated with one hand.

In principle, the recesses can have different sizes and numbers depending on the desired ergonomic point of view.

The first edge is in this case in the position for use with a bag, which is the upper edge of the closure means that defines the opening itself.

The second edge is in this case the limitation of the wall opposite the first edge.

By ring shape it is meant in this case a configuration, in which the two half-elements are complemented by even a hollow space, which is surrounded in the form of a sleeve or sleeve. In this case, the ring-shaped configuration may have a round or oval shape. However, other optional shapes are also conceivable, in which the edges and / or walls can be curved and / or straight and in which the edges or walls can be configured with or without buckling / cornering. In this case, the shape of the first edge can deviate from the shape of the second edge in a top plan view in the axial direction. Furthermore, the shape of the wall, which connects the two edges, can be equally deviated in the top plan view in the axial direction from the shape of one or both edges.

The axial direction is understood in this case as the direction parallel to the axis of the midpoint, extending through the midpoint, of the lines connecting the hinges, of a closure means in its extended configuration open in a first direction.

The radial direction is understood in this case as the direction extending perpendicular to the axial direction, of the closure means in its extended open configuration in a first direction.

Preferably, the hinges are arranged in the region of the first edge, especially the first edge.

Furthermore, it can preferably be provided that both half-elements preferably have at least one inlet in the area of the first edge which points in a radial direction inward. Furthermore, preferably in both half-elements at least two, more preferably at least three and more preferably at least four inputs may be present.

As an embodiment in at least one half-element, preferably in both half-elements, it is conceivable in this case, for example, a larger entrance with respect to the first edge of the half-element than a single relatively central entrance.

Furthermore, two, three or four entrances can also be provided in a semi-element.

An arrangement on the first edge with a smaller entrance as well as with a larger entrance is also conceivable. For example, the middle finger, the ring finger and the little finger can fit into the major entry, while the index finger fits into the minor entry.

Alternatively, two smaller inputs are also possible in one half-element, preferably in the two half-elements. In this case, then the thumb and ring finger can fit into the inputs of a semi-element.

If three inputs are provided in at least one half-element, preferably in both half-elements, it can be envisaged to arrange two smaller inputs in a half-element for the index finger and the little finger, as well as a larger central input for the middle finger and ring finger.

Preferably, the inputs are uniformly distributed over the half-element.

Preferably, the inputs may, however, also be different in size and number for each half-element.

The arrangement of the inlet can be adapted to the desired ergonomic aspects and depends, among other things, also on the size of the closure means, since the requirements can be modified with the size of the closure means as well as the application case. grip and retention of the closure means. Thus, for example, a closing means for a garbage bag that can be used as a traveler's disease bag, can have other means and can be retained in another way than, for example, a closing means for a garbage bag. , which is considerably larger and is used, for example, in medical practices and hospitals for the accommodation of contaminated bandages.

With regard to the recess, it is particularly preferable that both half-elements have a recess at the second edge.

Two, three or four recesses can be provided in a half-element.

In this case, particularly preferably, a single recess is provided in a half-element. In the embodiment of a single recess, this extends in particular over a large part of the periphery of the respective half-element. For example, three fingers or the flea can be accommodated in such a recess. In this case, it can also be provided that in this position the thumb also rests on one of the entrances of the first edge. The edge or the edge of the recess can in this case be profiled or not profiled. The profile can in this case consist, for example, of elevations and cavities. The profiled edge of the recess further improves ergonomics. By a profiled configuration of the recess in opposition, for example, to two or more recesses, it is understood that the edge of the recess does not return again to the level of the second edge, from which the recess starts, but rather the elevations and recesses they follow the development of the respective notch with respect to their level.

A closing means is particularly preferred, in which both retaining elements have at least one recess in the area of the first edge which points in a radial direction inwards and / or from the second edge at least one recess which extends in an axial direction. .

Furthermore, a closure means is particularly preferable, in which both half-elements have, respectively, an equal number of entrances and an equal number of recesses.

In a preferred embodiment of a closing means, each half-element has, respectively, only a single recess and preferably, respectively, one, two, three or four entrances.

In this case, it is especially preferred that the entrances and / or the recesses of one half-element are arranged on an imaginary straight axis that connects the hinges in axial mirror symmetry in position, contour and / or size in the other half-element. . Through such an axial symmetrical arrangement a universal application is possible, for example, regardless of whether the user is right-handed or left-handed.

Locking elements are provided for securing the half-elements to each other in the second position. The closure elements preferably comprise first closure elements and corresponding second closure elements.

Preferably, the first and / or second closing elements are arranged on the respective half-element, preferably in the area of the first edge, respectively alternating with the entrances.

An alternative arrangement of closure elements and gates contributes to the advantage of easier handling in the closure process in the area of the first edge.

Especially preferred, the first closing elements are arranged, respectively, only on one half-element and the second closing elements are arranged only on the other half-element. This can advantageously contribute to conducting the closing force in one direction.

But alternatively it is also possible that the first or second closing elements are arranged at least alternately on a respective half element. Such an arrangement of the closing elements can contribute to making the connection in the mooring more difficult to release or more stable, since the action of the force from different directions can be better compensated.

Examples for the first closure elements are projections, retaining projections, hooks and for the second closure elements corresponding holes, eyelets or edges, behind which the first closure elements can engage.

The configuration of a closure means is particularly preferred, in which at least one recess of a half-element is arranged in such a way that an inversion zone or point of inversion of the recess is arranged in the development of the half-element. in the center between the hinges. In this case, in the transition from the first to the second position, fencing with a guide and closing with one hand is especially possible. In this case, the point of inversion should be understood as the point of the notch, between which and the first edge the distance is minimal. By inversion zone is meant a zone or section of the recess, which results when not a point, but a plurality of neighboring points of the recess, such as a line, have the shortest distance from the first edge. If there is more than one point, but they are not immediately adjacent to each other and therefore do not form a line, they have the same shorter distance from the first edge, then the area between the two outer points forms the inversion area. If several recesses are provided, then each of the recesses can be configured correspondingly.

Especially preferred, at the height of an inversion zone, especially in the center with respect to the inversion zone or the inversion point of the recess, especially in its central arrangement in the development of the half-element between the hinges, is arranged at least one closure element, especially in the area of the first edge. In this way, with the ergonomic grip in the transition to the second position and then in the second position a primary fixation and a locking of the half-elements to each other can be achieved at least in this section. Another preferred embodiment can provide that the half-elements have along the first edge a first and a second element of guide means, which can engage in the second position for the formation of a guide means relative to each other.

Furthermore, in a preferred embodiment it is provided that one of the half elements has a first guide means element on its first edge, especially in the form of a first slot open in axial direction and the other half element has on its first edge a second guide means element, especially in the form of its first edge or a rib, and the two central guide elements can engage each other in the second position for the formation of a guide means. Alternatively, both central guide elements can be designed as grooves, as first and second grooves, with ribs delimiting the grooves, one rib then engaging in the respective other groove.

Especially in comparison with a groove of a half-element, in which a rib or the part of another groove of the other half-element is accommodated, to prepare a guide means, a labyrinth seal can additionally be achieved, which achieves an embedding Safe of the contents housed in the bag, especially garbage bag, especially waste with the bag fastening, especially garbage bag.

In this case, it is particularly preferred that the entrances are arranged in the development of the first and / or the second guide means element and in particular are formed there. The conditional angular modifications due to the realization of entrances in the development of the first and / or the second element of guide means contribute to the improved fastening process of the bag and reinforce a labyrinth seal conditioned by the guide means and contribute more to the tightness closing.

The closing elements preferably comprise as first closing elements retaining projections, which engage the second closing elements in the form of corresponding holes.

In this case, preferably, retaining projections are arranged on one of the half-elements, which pass through the holes in the second half-element and fasten them there.

More preferably, the closure elements comprise retention projections, wherein the retention projections project in an axial direction beyond the first edge of the half-elements, especially a rib of a half-element. In this way it is achieved that only one force component is necessary in the axial direction when the half-elements are transferred from the first to the second position.

This preferred embodiment with detent projections projecting beyond the first edge is therefore especially advantageous over detent projections, which extend exclusively below the first edge and point inward. In such a case, it is unfavorable that in the case of folding of the two half-elements to each other and during the closing a force action occurs which is not directed purely axially.

Especially preferred, the holes for engaging the retaining projections are arranged in the first and / or the second guide means element, especially in the first groove or in the second groove.

In this case, it is particularly preferred that one of the half-elements has on its first edge an open groove in the axial direction as a guide means, in which the other half-element engages with its first edge, especially with a rib, in the second position. In this case, it may be particularly preferred that the retaining lugs are provided in the region of the rib, in particular at the upper free end of the rib and that the holes for engaging the retaining lugs are provided in the groove, with preference at the bottom of the groove. In this way, the closing process, that is, the transfer of the closing means from the first to the second position, can be guided more safely and there is a lower inclination of the two half-elements relative to each other than in the state of the art, thereby enhancing the secure fit of the retention lugs in the holes. The number of the retaining projections and the respective holes can be varied from one to three, four or more and is influenced, inter alia, through the size of the closure means.

In a particularly preferred embodiment of the closure means, the wall of the half-elements has a shoulder pointing radially outward in the region of the first edge. In particular, the first edge is arranged at the shoulder end or forms the shoulder end. Through this shoulder it is possible to achieve that a bag, especially garbage bag, can be securely fixed through the closing means, especially under deformation of the bag or garbage bag, whereby the bag or garbage bag Trash is safely retained on the closure means. Furthermore, such an embodiment especially supports the stacking of the closing means to advantage.

According to a particularly preferred embodiment, provision can be made for the half-elements to comprise plastics, in particular to be made of plastics.

With particular preference, the half-elements, especially the closing means, are made of plastic as injection molded parts. In such a configuration, the arrangement of the retaining projections in the way that projects in the axial direction on the first edge represents a special advantage with respect to the demoulding of the injection casting from the tool.

The two half-elements in their joined configuration of the first position can be manufactured as such as injection molded parts.

The hinges, through which the two half-elements are connected to one another, can then in particular be designed as film hinges. The hinges are preferably provided on both sides of the half-elements. By film hinge is meant a configuration in which the hinge or joint is configured in one piece without other mechanical elements with the pieces to be joined, especially the semi-elements. Such hinges essentially consist of a thin-walled joint, which, through its elasticity, enables a certain rotational movement of the unit parts. Film hinges generally involve wall thickness jumps, that is, the film hinge has a smaller wall thickness than the parts to be joined.

In this case, it is especially preferred to configure the disposable closure means. However, in principle reusable configurations of the closure means are also conceivable.

To stabilize the closure means, provision can be made for the half-elements to be connected to each other in the region of the second edge, especially opposite the hinge, in the first position on a bridge made of breakable material, which is destroyed in the second position. . Such a material bridge can in particular be a wire-like connection between the two half-elements. The material bridge must in this case be sufficiently stable, on the one hand, to prevent an unwanted "folding", that is, a transfer from the first to the second position, at an undesired moment, especially during the use of the medium. closure with a bag, especially garbage bag and, on the other hand, so that it is easily destroyed to enable a transfer from the first to the second position without much effort.

Such a configuration can be made comparatively easily in an injection casting.

The half-element, especially the closure means, preferably comprises or is formed from plastic. In this case, plastics are used in particular, which are associated with thermoplastics, such as especially polyethylene, polypropylene, polystyrene, polyester, polyamide, acrylonitrile-butadiene-styrene (ABS), polyoxymethylene (POM), polycarbonate.

The use of thermoplastic plastics for the manufacture of the semi-elements or of the closure means as an injection molded part is especially preferred.

In this case, it is particularly preferred that the closure of the two half-elements to one another, that is to say the connection of the closure elements, is configured inseparably in the second position. Such a configuration is generally envisaged in disposable closure means. The lock can, however, also be removable, especially in the case of reusable closing means or adjustment systems.

Preferably, the half-elements have a corresponding shape at least in the area of their first edges, that is to say over the entire width of the first edges. In this case, it is possible to achieve that the half-elements support one another in particular over their entire length and in this way a secure closure of a garbage bag received by the closure means is achieved.

The semi-elements preferably have a ring shape, especially precisely semi-circular or in the shape of a semi-circular or semi-oval section. In general, other shapes are conceivable, which are not particularly rounded or not rounded at all or have sags / corners, although a rounded contour is preferred in view of ergonomic handling.

Furthermore, it is especially preferred that the wall, extending between the first and second edges, is configured closed at least 50% of the surface, preferably at least 70% and preferably at least 90%, more preferably 100%. In this way the stability can be increased.

If the second edge has recesses in the axial direction, the surface to be considered must be the surface that is formed between the second edge or the edge of the second inlet and the first edge.

In a particularly more preferred manner, a thickening of the wall is provided along the second edge in the form of a material reinforcement, especially preferred in the form with rounded edges. This supports the stability of the wall in the case of application, especially during the transfer of the semi-elements from the first to the second position, as well as preparing a comfortable grip for the user and therefore ergonomic handling. of the semi-elements or of the closing means.

The invention further relates to a container with a closure means and a bag, especially an evacuation container with a garbage bag, wherein the bag, especially garbage bag, has surrounding side walls as well as a lower end. closed and an open upper end, wherein the bag or garbage bag can be secured by folding the open upper end from the inside out over the first edge in the closure means, wherein the closure means is configured as described. previously described.

It also comprises a set of a bag, especially a garbage bag, which is configured as described above with surrounding side walls as well as with a closed lower end and an open upper end as well as with a closing means as described above. , wherein the bag or garbage bag can be fixed by folding the open upper end from the inside out over the first edge in the closure means, wherein the junction of the bag or garbage bag and the closure means are performed only immediately prior to application and in the packaged and ready-made state for operation, the garbage bag or bag and the closure means are separated. Such an arrangement is especially desirable, if the closure means is configured to be reusable several times. Such an arrangement is also desirable when defined embodiments of bags must be available out of necessity or depending on the situation.

Other advantages and characteristics of the invention are deduced from the other documents of the application.

The invention is explained in detail below with the aid of a drawing.

Figure 10 shows two stacked closure means considered from the second edge.

Figure 1 shows a preferred embodiment of a closing means for bags, especially garbage bags according to the present invention, the closing means being provided in its generality with the reference sign 10. The closing means has a first edge 12 as well as a second edge 14. Between the first 12 and the second edge 14 extends a wall 16. The closing means 10 comprises in this case two half-elements 18 and 20. The two half-elements 18, 20 together form , connected on two hinges 22, here preferably on film hinges 22, the closing means 10. In this case, the film hinges 22 are arranged in the area of the first edge 12. In a first position shown in FIG. 1, the half-elements 18, 20 are connected to each other in the area of the second edge 14 on a material bridge 24. The material bridge 24 stabilizes the first position shown in figure 1 and counteracts an articulation around the hinges of pel Plate 22. The material bridge 24 is configured in this case in such a way as to allow sufficient stability in the case of use of a closure means 10 shown in the first position, but it can be destroyed quite easily to transfer without further expense. force the closure means from a first to a second position. The wall 16 of each half-element 18, 20 between the first edge 12 and the second edge 14 is essentially flat. In the area of the film hinges 22, between the film hinge 22 and the material bridge 24, a gap 28 is provided between the two half-elements 18, 20.

Through the otherwise full-surface configuration of the wall 16, the stability of the closure means is improved. In the area of the first edge 12, the closing means 10 has for each half element 18, 20 two inlets 30 which extend radially inward. These entrances serve for the secure and ergonomic grip and retention of the closure means. In this way, during closing with one hand, the thumb can rest on an entrance 30, which serves as a gripping cavity for a semi-element, and depending on the size of the hand and the arrangement, the other fingers of the same hand may engage during one-handed grip on the remaining inputs 30 of the second half-element. In this way, one-handed handling can also be better ensured.

Furthermore, the closing means 10 has for each half element 18, 20 a recess in the second cellar 14, which extends in the axial direction. The recesses are here provided with the reference sign 32. These recesses 32 are ergonomic when the closing means 10 is grasped from the sides of the second edge 14, especially during the transfer from the first to the second position, especially when it is already partially carried out. the process of articulation around the hinge, especially film hinge 22. In order to be able to fix both semi-elements 18, 20 in a second position relative to each other, closing elements are provided, especially first closing elements 33a and corresponding second closing elements 33b . Preferably, the first closure elements 33a comprise retaining lugs 34 and the retaining lugs 34 rise in an axial direction over the first edge 12.

In the wall 16, holes 36 are provided directly below the retaining projections 34. These holes 36 can represent diversion and discharge free spaces for the bag.

Furthermore, the first half-element 18 has on the first edge 12 a rib 38 which preferably extends over the entire length of the section of the half-element, which rises in the axial direction from the closure means 10. As opposed to Therefore, the second half-element 20 has a groove 40, which is delimited by two ribs 42 and 44, with holes 46 being provided in the bottom of the groove as part of the closing element as a second closing element 33b, which correspond with retention projections 34 as the first closure element 33a and which are traversed by the retention projections 34, so that the detent projections 34 are fixed with the retention effect.

Through the engagement of the rib 38 in the groove 40 a kind of labyrinth seal is formed. Since the insertion of the rib 38 in the groove 40 is already carried out when the articulation movement from the first to the second position has not yet been fully completed, the groove 40 with its ribs 42 and 44 serves as the first guide means element 39a for the rib 38 as the second guide means element 39b and thus ensures that the retaining projections 34 can be inserted without much effort into the holes 46 and are correctly positioned therein.

The retaining projections 44 extend in this case, as indicated, in the axial direction over the first edge 12 of a half-element 18, where the retaining free sections 48 point radially inward.

FIG. 2 now shows a configuration of the closing means 10 from the second edge 14 and in particular also shows the recesses 32 of the second edge 14. Furthermore, as can be seen in FIG. 1, the closing means 10 has in the region of the first edge 12 a shoulder 50 pointing radially outward. The first edge 12 is preferably arranged at the end of the shoulder 50. This radially outward-pointing shoulder serves for the secure attachment of a bag, especially a garbage bag, which is guided with its opening through the interior of the medium. closure 10 and is then placed on the first edge 12 under the deformation of the bag or the garbage bag. As opposed to radially outward-pointing retaining lugs 34, in this case, in axially upward-pointing retaining lugs 34 according to the invention, during overlapping of the garbage bag on the closure means 10 there is a further risk reduced from tearing of the garbage bag 10 especially before or during use.

Figure 3 now shows a situation, in which the two half-elements 18, 20 are transferred around the hinges 22 already from the first to the second position. To this end, a fold can be made from the entrances 30 to the recesses 32, which are preferably arranged as a single recess 32, respectively, in the center in one of the half-elements 18, 20 and allow easy retention and guidance. of the closure means 10 with one hand. During the closing movement, the rib 38 engages in the groove 40, so that the half-element 18 is guided with respect to the half-element 20, thereby facilitating the positioning of the retaining projections 34 in the Holes not shown in figure 3. The articulation movement is in this case carried out in the direction of the arrow 52. It can also be recognized that during the articulation movement around the hinges 22, the material bridge 24 has already been destroyed . It can also be recognized that the inlets 30 are arranged in the development of the groove 40 as the first guide means element 39a and in the development of the rib 38 as the second guide means element 39b and are inserted there.

Figure 4a) now shows a closing means in a fully closed configuration, that is, in the second position, so that the retaining projections 34 of a half-element 18 pass through the holes in the slot of the half-element 20. Through the recesses 32 the closing means 10 is now reduced in the height of the wall, so that the half-element (s) 18, 20 can also be manipulated well with one hand.

The recesses 32 are configured in this case not profiled and are arranged in the center between the hinges 22 and in particular in such a way that their reversal point 35, the point of the shortest distance from the first edge 12 in the development of the semi- element 18, 20 is also arranged in the center between the hinges (22). By virtue of the regular shape of the circular arc of the recess 32 in FIG. 4a, only one point has a shorter distance. More advantageously, as shown in FIG. 4a, at the height of an inversion zone or inversion point 35 of the notch 32, especially in its central arrangement in the development of the semi-element 18, 20, at least A closure element 33a, 33b is arranged in particular in the area of the first edge.

The configuration of the retaining projections 34 with the holes 36 as well as the rib 38 is shown in FIG. 5 again in an enlarged representation.

Figures 4b) to 4d) show alternative configurations of the closing means with respect to the configuration of the recesses 32. In this case, Figure 4b) shows a configuration in which instead of a large recess arranged centrally between the hinges 22, two smaller recesses are provided, which are arranged on both half-elements (18, 20) equally, that is to say, symmetrical to the axis connecting the hinges 22. With respect to the respective half-element 18, 20 both are provided cutouts 32 of the same size and geometry and with the same distance from the hinges 22.

Figures 4c) and 4d) show configurations, in which the recess 32 has a profiled edge shape. In this case, recesses 32v and elevations 32e are provided on the edge of the recess 32. These are arranged alternately in the form of waves, in particular an odd number of elevations 32e and cavities 32v being provided. Figures 4c) and 4d) differ in this case by the number and height of the cavities 32v and the elevations 32e. By means of such profiling, handling and ergonomics can be further improved.

Figure 6 shows in an enlarged representation the second position and here the engagement of the retaining projections 34 of the half-element 18 in the holes 46 of the half-element 20. In this case, the immersion of the rib 38 in the first edge 12 with the retaining projections 34 in the groove 40, formed by the two ribs 42 and 44 and the engagement in the holes 46. The clamping is carried out in this case essentially inseparable, that is, only under planned destruction of one of the components. The closure means 10, as shown in the previous figures, is preferably manufactured as an injection molded part. Due to the upward pointing retaining projections, a particularly easy and good release is achieved. The two half-elements 18, 20 have a corresponding shape, essentially a rounded shape, which makes it possible, on the one hand, for the two half-elements to fully support each other with respect to their first edges 12 and the rib 38 of a half-element. it fits into the guide means element of the groove 40 of the other half element. For other partly, in this way a stacking of the closing means 10 is achieved, which is shown in figure 10. The storage is simplified in this way.

In FIGS. 7a) - 7f) different schematic conceivable arrangements of inlets 30 in the area of the first edge 12 are shown in a top plan view.

For universal application and use, it is particularly advantageous if the entrances 30 are arranged on both half-elements 18, 20 on a linear axis 19 connecting the two hinges 22, symmetrically to the axis, and are advantageously equal in contour and size. .

Thus, for example, at least one (figure 7a), more preferably two (figure 7b, figure 7c), more preferably three (figure 7d, figure 7e) and more preferably four entrances (figure 7f) may be provided in a respective semi-element.

The closing elements, especially as first closing elements 33a and as corresponding second closing elements 33b, which are provided for clamping and locking the two half-elements 18, 20 in the second position, are preferably arranged in the first respective edge 12 of a respective half-element 18, 20 alternating with the entrances 30. In an especially preferred embodiment, the first closing elements are provided in this case only on one half-element 18 and the second closing elements are only provided in the other half-element 20, as schematically indicated in figures 7a) - 7e) for the first closing elements with the reference sign 33a and for the second closing elements with the reference sign 33b. The first closing elements 33a can preferably be designed as retaining projections, the second closing elements 33b can preferably be designed as openings.

FIG. 8 now shows a container, especially an evacuation container or a bag or garbage bag assembly 60 as well as closure means 10. The garbage bag or garbage bag 60 in this case has a circumferential wall 62 as well as a closed lower end 64 and an open upper end 66. With the upper end open, the bag or garbage bag 60 is guided through the center of the closure means 10 and in particular placed under deformation from the inside out on the first edge 12 of the closing means 10, doing this especially under elastic and / or plastic deformation of the bag or garbage bag 60, so that the bag or garbage bag 60 is retained by friction and in positive connection in the middle of closure 10. Such a bag or garbage bag 60 together with a closure means 10 in the first position is shown in figure 8.

Figure 9 shows a configuration, in which the closure means 10 is in a position similar to that of figure 3, that is, between a first position and a second position, the material bridge 24 being destroyed and an articulation is made around hinge 22.

If the retaining projections 34 now enter the holes 46, then depending on the elasticity of the bag or garbage bag 60, a collision of the bag 60 in this area or another elastic or plastic deformation occurs.

The garbage bag or bag 60 with the contents housed in it, especially garbage, is then securely closed and can be guided for subsequent evacuation.
