Description

The present invention relates to a closure means for bags, in particular waste bags comprising two half-members each having a first and a second axially spaced edge and having a wall extending axially between the first and second edges, and wherein the half-members are hinged together are connected and complement each other in a ring-like manner and are pivotable about the hinges in a second position, that the half-elements come to lie with their first edge to each other, and wherein closure elements are provided which lock the half-elements in the second position to each other.

Such closure means for bags, in particular waste bags are known in the art. Travel sickness is a frequent area of use, but also other cases of vomiting. In addition, other areas of use for bags, in particular waste bags come into consideration, in which a safe retention of the opening of the bag or waste bag by clamping the same is desired and then a secure closure of the content, in particular the waste is achieved.

Such closure means have a first and a second edge, wherein the first edge is the upper edge in use, which determines the actual opening for a user. If a bag or waste bag is used with such a closure means, the bag or waste bag is passed in the region of its open end through the interior of the closure means and this area of the bag or waste bag is folded over the first edge of the closure means. In this case, the first edge of the closure means is overlapped by the bag or waste bag from the inside out. Here, the bag or waste bag is preferably set under deformation in an elastic and / or plastic manner.

With such closure means, the opening of the bag or waste bag can be securely kept open, whereby contamination of the opening area of a so-held bag or waste bag can be better avoided. Prevention of contamination is particularly desirable in the case of contents, in particular waste, which is subsequently to be closed safely and without contact.

For example, in the prior art, as in US4610039 or US20070031068 described or in the Insert closure means known, wherein a closure of the bag takes place in that the bag is twisted below the lower second edge of the closure means and the twisted region is then hooked in a notch provided on the second edge of the closure means. A disadvantage of this design is that soiling, which are located in the immediate area of the closure means, are not reliably detected by such a closure of the waste bag. The disposal of such a waste bag can still be perceived as unhygienic.

The WO 2009/021268 A1 describes a disposable waste container for use in ambulances, hospitals, but also for travel applications comprising a waste bag and a closure means. The application describes different ways of closing the bag. It is already known from the prior art for a, to provide a design in which also a twisted waste bag is hooked into a notch. Furthermore, it is described to provide a film hinge in the region of the first edge and a destructible connection in the region of the second edge, so that a collapse of the two half-elements in the direction towards each other is possible and thus a relief of the guided over the closure means waste bag and thus a removal thereof. In addition, it is also already known to design the closure means in such a way that the two half elements come to rest on one another and are locked together by means of closure elements. The known from the prior art such closure means are often poorly available, so unwieldy. It was also found that the two half-elements can often only be folded and closed using both hands. however There are often situations in which the user or even the enrichment of a bag equipped with such a closure means does not have both hands available.

The invention solves this problem by a closure means for bags, in particular waste bags of the type mentioned, wherein it is provided according to the invention that at least one half element in the region of the first edge has at least one radially inwardly facing indentation and / or starting at least one half element has at least one recess extending in the axial direction from the second edge.

It is thereby achieved that by means of a recess and / or a recess on the respective edge introduced contouring within a continuous course of a Halbelements the closure means advantageously ergonomically manageable is designed, which also reduces the effort in the Verschließführung from the first position in the second position causes.

The recesses pointing inward in the radial direction serve for gripping the closure means on the one hand when using such a closure means for a bag, in particular waste bags during use, wherein the bag, in particular waste bags can be held on the closure means and fingers can engage in the recesses and so improve the grip. In addition, these recesses, which can serve as recessed grips, also serve to facilitate the transfer of the closure means from the first to the second position, since this attack points are given for the fingers of a hand.

Further preferably, at least two, more preferably at least three, and more preferably four indentations may be provided on a half-element.

Basically, the indentations may have different sizes and numbers depending on the desired ergonomic point of view.

The opening extending from the second edge in the axial direction serves, in particular, to enable gripping of the closure means from the underside and in particular to receive the hand and a guide of the hand in an ergonomic manner when transferring from the first to the second position and during the merging of closure elements, such as when inserting locking lugs in corresponding openings to allow. The closing of the two half-elements on each other and the locking of the two half-elements together is so much easier. These recesses are used in particular to allow after a first gripping and holding the closure means by fingers in the region of the first edge during use encompassing and then a safe transfer from the first to the second position and latching with the least possible force. Depending on the design, the reduction of the height of the wall of the half-element introduced with a recess makes it possible to handle the closing means well with one hand.

Basically, the recesses may have different sizes and numbers depending on the desired ergonomic point of view.

The first edge is in the use position with a bag of the upper, the actual opening defining edge of the closure means.

The second edge is the boundary of the wall opposite the first edge.

Ring-like is to be understood here as meaning a design in which the two half-elements complement each other with the inclusion of a cavity, which they enclose in the manner of mantles or cuffs. The ring-like design may have a round or oval shape. Also conceivable, however, are any other shapes in which the edges and / or walls can be curved and / or straight and in which the edges or walls can be formed with kinks / corners or without them. In this case, the shape of the first edge of the shape of the second edge deviate in a plan view in the axial direction. Moreover, the shape of the wall connecting the two edges may also deviate in the axial direction from the shape of one or both edges when viewed from above.

In this case, the axial direction is understood to be the direction parallel to the midpoint axis, which runs through the center, the straight line connecting the hinges, of a closure means in its open, spread configuration in a first position.

The radial direction is understood here as the direction perpendicular to the axial direction, the closure means in its open, spread configuration in a first position.

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

Further preferably, it can be provided that preferably both half-elements in the region of the first edge have at least one indentation pointing inwards in the radial direction. Further preferably, at least two, more preferably at least three and more preferably at least four indentations may be present on both half-elements.

Conceivable as an embodiment of at least one half-element, preferably on both half-elements, is for example a larger indentation with respect to the first edge of the half-element as a relatively central single indentation.

In addition, two, three or four indentations may be provided on a half-element.

It is also conceivable arrangement on the first edge with a smaller indentation and a larger indentation. For example, the middle finger, ring finger and the little finger can engage in the larger indentation while the index finger engages in the smaller indentation.

Alternatively, at least on one half element, preferably on both half elements, two smaller indentations are possible. In this case, index fingers and ring fingers can preferably then engage in the indentations of the one half-element.

If at least on a half-element, preferably on both half-elements, three indentations are provided, it may be provided to provide two smaller indentations on a half-element for the index finger and the little finger and a larger central indentation for middle and ring finger.

Preferably, the indentations are evenly distributed over the half-element.

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

The arrangement of the indentation can be adapted to the desired ergonomic aspects and depends i.a. also on the size of the closure means, since change with the size of the closure means and the application, the requirements for gripping and holding the closure means. For example, a closure means for a garbage bag used to be used as a motion sickness bag will have and have different dimensions than, for example, a closure means for a garbage bag that is significantly larger, e.g. used in medical practices and hospitals to take in contaminated bandages.

With regard to the recess, it is particularly preferred if both half-elements have a recess on the second edge.

There may be two, three or four recesses provided on a half-element.

Particular preference is given to the provision of a single recess on a half-element. In the embodiment of a single recess, this extends in particular over a large part of the circumference of the respective Halbelements. In such a recess, for example, three fingers or the thumb ball can be recorded. In this case, it may furthermore preferably be provided that, in this position, the thumb continues to lie in one of the indentations of the first edge.

The edge or the edge of the recess can be designed contoured or unconstrained. The contouring may consist for example in elevations and depressions. A contoured edge of the recess helps to further improve the ergonomics. Under a contoured configuration of the recess in contrast to, for example, two or more recesses is to be understood when the edge of the recess does not return to the level of the second edge from which the recess emanates, but the elevations and depressions in terms of their level the course follow the respective recess.

Particularly preferred is a closure means in which both half-elements in the region of the first edge have at least one inward pointing indentation in the radial direction and / or starting from the second edge at least one extending in the axial direction recess.

Furthermore, a closure means, in which both half elements each have an equal number of indentations and an equal number of recesses, is particularly preferred.

In a particularly preferred embodiment of a closure means, each half element each has only a single recess and preferably in each case one, two, three or four indentations.

It is particularly preferred if the indentations and / or the recesses of a half-element are arranged on an axis connecting the hinges imaginary straight axis in position, contour and / or size in the other half-element. Such an axisymmetric arrangement is a universal application, for example, regardless of whether the user is a right-handed or left-handed, possible.

For locking the half-elements to one another in the second position, closure elements are provided. The closure elements preferably comprise first closure elements and corresponding second closure elements.

Preferably, the first and / or second closure elements on the respective half-element, preferably in the region of the first edge, each arranged alternately with the indentations.

An alternating arrangement of closure elements and recesses advantageously contributes to a simpler handling in the closing process in the region of the first edge.

In particular, the first closure elements are each arranged only on one half element and the second closure elements only on the other half element. This can advantageously contribute to a Verschießkraftführung in one direction

Alternatively, however, it is also possible that the first or second closure elements are arranged at least alternately on a respective half-element. Such an arrangement of the closure elements can contribute to the fact that the connection becomes harder to release or become more stable during latching, since forces acting from different directions can be better compensated.

Examples of first closure elements are projections, latching noses, hooks and, for corresponding second closure elements, openings, eyes or edges, behind which the first closure elements can engage.

Particularly preferred is the execution of a closure means, wherein at least one recess of a Halbelements is arranged such that a turning region or inflection point of the recess in the course of the Halbelements is arranged centrally between the hinges. Here, in the transfer from the first to the second position in particular encompassing with a one-handed guidance and closure is possible. Here, the point of the recess is to be understood by inflection point, between which and the first edge of the distance is the shortest. Turnaround is understood to mean a portion of the recess that results when not one point but a plurality of adjacent points of the recess, such as a line, have the shortest distance to the first edge. If more than one point, but not immediately adjacent, and therefore forming no line, have the same shortest distance to the first edge, so the area between the two outer of these points forms the turning area. If several recesses are provided, then each of the recesses can be designed accordingly.

Particularly preferably, at the level of a turning region, in particular centrally with respect to the turning region or inflection point of the recess, in particular in its central arrangement in the course of the half-element between the hinges, at least one closure element, in particular in the region of the first edge, arranged. Thus, in the ergonomic gripping during the transfer to the second position and then in the second position, a primary fixing and locking of the half elements to each other at least in this section can be achieved. A further preferred embodiment can provide that the half-elements along the first edge have a first and a second guide means element, which in the second position for forming a guide means can engage with each other.

Furthermore, a preferred embodiment provides that one of the half elements has at its first edge a first guide means element, in particular in the form of a first groove open in the axial direction and the other half element at its first edge a second guide means element, in particular in the form of its first edge or a Has rib and the two guide means elements can engage in the second position to form a guide means. Alternatively, both guide means elements may be formed as a groove, as a first and second groove, with the grooves defining ribs, wherein a rib per groove then engages in the respective other groove.

In particular, in conjunction with a groove of a half-element, into which a rib or part of another groove of the other half-element is received to provide a guide means, a labyrinth-like closure can be achieved, which securely encloses the contents contained in the bag, in particular waste bags , in particular waste obtained under clamping of the bag, in particular waste bag.

It is particularly preferred if the indentations are arranged in the course of the first and / or second guide means element and in particular are introduced therein. The caused by the introduction of indentations angle changes in the course of the first and / or second guide means element contribute to improved Einklemmvorgang the bag and reinforce a conditional by the guide means labyrinthine Closure and so contribute to the tightness of the closure.

The closure elements preferably comprise latching lugs as first closure elements, which engage in the second closure elements in the form of corresponding openings.

In this case, latching lugs are preferably attached to one of the half-elements, pass through the openings in the second half-element and lock there.

Further preferably, the closure elements can comprise latching noses, wherein the latching noses protrude in the axial direction beyond the first edge of the half elements, in particular a rib of a half-element. This ensures that only a force component in the axial direction is necessary when the half-elements are transferred from the first to the second position.

This preferred embodiment with over the first edge protruding locking lugs is thus particularly advantageous against locking lugs, which extend exclusively below the first edge and point inwards: In such a case, it is disadvantageous that when folding the two half-elements together and when closing it comes to a force which is not purely axially directed.

Particularly preferably, the openings for engagement of the latching lugs in the first and / or second guide means, in particular in the first groove or second groove are arranged.

In this case, it is particularly preferred if one of the half elements has at its first edge an open groove in the axial direction as guide means into which the other half element engages with its first edge, in particular with a rib, in the second position. It can be particularly preferred that the locking lugs in the region of the rib, in particular at the upper free end of the rib, are provided and the openings for engagement of the latching lugs in the groove, preferably in the groove bottom, are provided. In this way, the process of closing, so the transfer of the closure means from the first to the second position, be performed safely and it is less than in the prior art to tilt the two half-elements to each other, whereby the secure engagement of the locking lugs in the openings improved becomes. The number of locking lugs and the associated openings can vary from one to three, four or more and is influenced, inter alia, by the size of the closure means.

In a particularly preferred embodiment of the closure means, the wall of the half-elements in the region of the first edge on a radially outwardly facing shoulder. In particular, the first edge is arranged at the end of the shoulder, or forms the end of the shoulder. Through this shoulder can be achieved that a bag, in particular waste bag can be securely clamped by the closure means, in particular under deformation of the bag or waste bag, whereby the bag or waste bag is securely held on the closure means. In addition, such an embodiment particularly advantageously supports the stackability of the closure means.

According to a particularly preferred embodiment it can be provided that the half-elements comprise plastics, in particular consist of plastic.

Particularly preferably, the half elements, in particular the closure means made of plastic as injection molded parts. In such a configuration, the arrangement of the locking lugs in the axial direction over the first edge protruding form a particular advantage with regard to the releasability of the injection molded part from the tool.

The two half-elements in their connected configuration of the first position can be produced as such as an injection-molded part.

The hinges, via which the two half-elements are connected to each other, can then be designed in particular as film hinges. The hinges are preferably provided on both sides of the half-elements. Under film hinge is understood a design in which the hinge or joint is integrally formed without further mechanical elements with the parts to be joined, in particular the half-elements. Such hinges consist essentially of a thin-walled connection, which allows by their flexibility a certain rotational movement of the connected parts. Film hinges are usually associated with wall thickness jumps, i. the film hinge has a smaller wall thickness, as the parts to be joined.

It is particularly preferred to make the closure means disposable. In principle, however, also recyclable designs of the closure means are conceivable.

To stabilize the closure means can be provided that the half-elements in the region of the second edge, in particular the hinges opposite, are connected to each other in the first position via a destructible material bridge, which is destroyed in the second position. Such a material bridge may in particular be a thread-like connection between the two half-elements. The material bridge must be sufficiently stable on one side to be able to Unintentional "folding", ie a transfer from the first to the second position, to prevent an undesired time, especially during the use of the closure means with a bag, especially waste bags and on the other hand easy enough to destroy, without much effort To enable transfer from the first to the second position.

Such a design can be realized relatively easily in an injection molded part.

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

Particularly preferred is the use of thermoplastics for the production of the half-elements or the closure means as an injection molded part.

It is particularly preferred if the locking of the two half-elements on each other, so the connection of the closure elements in the second position is designed insoluble. Such a configuration is usually provided for disposable closure means. However, the lock can also be made detachable, especially in reusable closure means or set systems.

The half elements preferably have a corresponding shape at least in the area of their first edges, ie over the entire area of the first edges. In this case can be achieved that the half-elements abut each other in particular over their entire length and so a secure closure of a received by the closure means waste bag is achieved.

The half elements preferably have a ring-like, in particular exactly semicircular or circular section-shaped or a semi-oval shape. Other shapes that are not rounded in particular or not rounded at all or have kinks / corners are quite conceivable, although with a view to ergonomic handling a rounded contour is preferred.

It is furthermore particularly preferred if the wall extending between the first and the second edge is at least 50% of the area, preferably at least 70% and preferably at least 90%, more preferably 100% closed. This can increase the stability.

If the second edge has recesses in the axial direction, the surface to be considered should be the surface formed between the second edge or the edge of the second recess and the first edge.

Particularly preferably, a thickening of the wall in the form of a material reinforcement, particularly preferably in the embodiment with rounded edges, is provided along the second edge. This supports the stability of the wall in the application, especially during the transfer of the half-elements from the first to the second position, as well as providing the user with a comfortable grip and thus ergonomic handleability of the half-elements or the closure means.

The invention further relates to a container with a bag, in particular a disposal container with a waste bag, the bag, in particular waste bag having circumferential side walls, and a lower closed end and an upper open end, wherein the bag or waste bag by folding the upper open End from the inside to the outside over the first edge of a closure means can be fixed, wherein the closure means is configured as described above.

Also included is a set of a bag, in particular a waste bag formed as described above with circumferential side walls and a lower closed and an upper open end and a closure means as described above, wherein the bag or waste bag by folding the upper open end can be fixed from the inside to the outside over the first edge of the closure means, wherein the joining of bag or waste bag and closure means only takes place immediately before use and in the packaged and ready for sale state bag or waste bag and closure means are separate. Such an arrangement is particularly desirable if the closure means is designed to be reusable. Such an arrangement is also desirable if needs-based or situation-dependent definitions of bags are available for selection or should be provided.

Further advantages and features of the invention will become apparent from the remaining application documents. The features are essential to the invention alone or in any combination with each other.

The invention will be explained in more detail below with reference to a drawing.

FIG. 1 shows a preferred embodiment of a closure means for bags, in particular waste bags according to the present invention, wherein the closure means is provided in its entirety by the reference numeral 10. The closure means has a first edge 12 and a second edge 14. Between the The first 12 and the second edge 14, a wall 16 extends. The closure means 10 comprises two half-elements 18 and 20. The two half-elements 18, 20 together, via two hinges 22, here preferably connected via film hinges 22, the closure means 10. Die Film hinges 22 are arranged in the region of the first edge 12. In an in FIG. 1 In the first position shown, the half elements 18, 20 are connected to one another in the region of the second edge 14 via a material bridge 24. The material bridge 24 stabilizes the in FIG. 1 shown first position and counteracts a pivoting about the film hinges 22. The material bridge 24 is designed so that it allows sufficient stability when using a closure means 10 shown in the first position, but can be destroyed easily enough to transfer without much effort, the closure means from a first to a second position. The wall 16 of each Halbelements 18, 20 between the first edge 12 and the second edge 14 is formed substantially over the entire surface. In the area of the film hinges 22, a gap 28 is provided between the film half 22 and the material bridge 24 between the two half elements 18, 20.

By the otherwise full-surface design of the wall 16, the stability of the closure means is improved. In the region of the first edge 12, the closure means 10 has two indentations 30 extending radially inward for each half element 18, 20. These recesses serve to grasp and secure and ergonomic retention of the closure means. Thus, when holding with one hand, for example, the thumb in a recess 30, which serves as a grip of a Halbelements come to rest, and depending on hand size and arrangement, the other fingers of the same hand with one hand holding in the rest Recesses 30 engage the second Halbelements. As a result, the handling can be better ensured even with one hand.

In addition, the closure means 10 per half element 18, 20 has a recess on the second edge 14, which extends in the axial direction. The recesses are provided here with the reference numeral 32. These recesses 32 then come into play ergonomically when the closure means 10 is gripped from the side of the second edge 14, in particular when transferring from the first to the second position, in particular when the pivoting process around the hinge, in particular the film hinge 22, has already taken place partially. In order to be able to fix the two half elements 18, 20 in a second position on one another, closure elements, in particular first closure elements 33a and corresponding second closure elements 33b, are provided. Preferably, the first closure elements 33a include latching noses 34 and wherein the latching noses 34 rise in the axial direction over the first edge 12.

In the wall 16 34 openings 36 are provided immediately below the locking lugs. These openings 36 can represent evasive and relief clearances for the bag.

In addition, the first half-element 18 at the first edge 12 has a preferably extending over the entire section length of the half-element rib 38 which rises in the axial direction of the closure means 10. In contrast, the second half member 20 has a groove 40 which is bounded by two ribs 42 and 44, wherein openings 46 are provided as part of the closure element as the second closure elements 33b on the groove bottom, with the locking lugs 34 as the first Closure element 33a correspond and which are penetrated by the latching lugs 34, so that the latching lugs 34 are fixed detent.

By engaging the rib 38 in the groove 40 a kind of labyrinth seal is formed. Since the engagement of the rib 38 in the groove 40 already takes place when the pivoting movement is not completed from the first to the second position, the groove 40 serves with its ribs 42 and 44 as the first guide means member 39a for the rib 38 as a second guide means element 39b and thus ensures that the locking lugs 34 can be inserted into the openings 46 without great force and are positioned correctly to these.

The locking lugs 34 extend, as stated, in the axial direction over the first edge 12 of a half-element 18, wherein the free latching portions 48 point radially inward.

FIG. 2 now shows a design of the closure means 10 from the second edge 14 ago and in particular also shows the recesses 32 of the second edge 14. In addition, can be, as well as in FIG. 1 see that the closure means 10 in the region of the first edge 12 has a radially outwardly facing shoulder 50. The first edge 12 is preferably located at the end of the shoulder 50. This radially outwardly-facing shoulder serves to secure a bag, in particular a waste bag, which is guided with its opening through the interior of the closure means 10 and then over the first edge 12 is placed under deformation of the bag or waste bag. In contrast to locking lugs 34 which point radially outward, in the case of the axially upward-pointing latching lugs 34 according to the invention, when the waste bag is slipped over the closure means 10 a lower risk that the waste bag 10 is torn, in particular before or during use.

FIG. 3 now shows a situation in which the two half-elements 18, 20 are already transferred to the hinges 22 from the first to the second position. For this purpose, a gripping of the indentations 30 in the recesses 32 take place, which are preferably arranged as a single recess 32 each centrally on one of the half-elements 18, 20 and allow easy holding and guiding 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, whereby the positioning of the locking lugs 34 in the in FIG. 3 not shown openings is facilitated. The pivoting movement takes place in the direction of arrow 52. It can also be seen that during the pivoting movement about the hinges 22, the material bridge 24 is already destroyed. It can also be seen that the recesses 30 are arranged in the course of the groove 40 as the first guide means element 39a and in the course of the rib 38 as the second guide means element 39b and are inserted therein.

FIG. 4a ) now shows a closure means in a fully closed configuration, ie in the second position, wherein the latching lugs 34 of the one half-element 18 engage through the openings in the groove of the half-element 20. Through the recesses 32, the closure means 10 is now reduced in height of the wall, so that it or the half-elements 18, 20 is also easy to handle with one hand.

The recesses 32 are formed in an uncontoured manner and are each arranged centrally between the hinges 22 in such a way that their inflection point 35 of the point shortest distance to the first edge 12 in the course of the half-element 18, 20 also centrally between the hinges (22) is arranged. Due to the uniform circular arc shape of the recess 32 in FIG. 4a only one point has a shortest distance. Advantageously, as in FIG. 4a shown at the level of a turning region or inflection point 35 of the recess 32, in particular in the central arrangement in the course of the half-element 18, 20, at least one closure element 33a, 33b, in particular in the region of the first edge, arranged.

The configuration of the locking lugs 34 with the openings 36 and the rib 38 is in FIG. 5 shown again in an enlarged view.

The FIGS. 4b) to 4d ) show alternative embodiments of the closure means with respect to the configuration of the recesses 32. It shows FIG. 4b ) a design in which instead of a large centrally between the hinges 22 arranged recess two smaller recesses are provided which are equally on both half-elements 18, 20 arranged symmetrically to the axis connecting the hinges 22. Based on the respective half-element 18, 20 both recesses 32 of the same size and geometry and with the same distance to the hinges 22 are provided.
