Description

The invention relates to a container, in particular for coating compositions such as paint or the like, with a lid which closes a container opening and a stripping grid which can be fixed to the container in a transport position and in a working position, according to the preamble of claim 1. The invention also relates to a stripping grid, as described for such a container.

Such wiping grids are often used when applying coating compositions such as paint in order to wipe off excess coating composition from an application tool such as a roller or brush, in order then to apply the coating composition to the respective surface. The stripping grid is arranged on the closed container during transport, for example on the top of the lid. In the working position of the stripping grid, it is attached to the edge of the container and at least partially protrudes upwards from the container opening in order to be able to use this partial area of to be able to wipe off excess coating composition from the application tool, with access to the interior of the container being made possible. To fix the stripping grid, the retaining projection or projections are arranged on the outside of the container side wall. The respective retaining projection is laterally bounded by a receptacle which receives the upper edge area of the container.

However, containers or bundles are subject to increased stresses, particularly during transport or handling, for example even when several containers are stacked on top of one another. Lateral forces can act on the containers, with the tendency to move containers stacked on top of each other laterally, as well as tilting forces, so that increased loads are exposed on peripheral areas of the lid or a stripping grille arranged on the top. This can lead to damage to the wiper grille, since on the one hand the wiper grille is directly stressed by a stacked container. On the other hand, the mechanical connection between the lid and the container is generally much more stable in order to ensure a tight closure of the container when forces are applied than the attachment of the stripping grid to the container so that it can be easily separated from the container for handling. On the other hand, however, this means that the stripping grid can easily suffer damage, for example when transporting containers stacked on top of one another, or is undesirably detached from the container. This applies in particular to areas of the stripping grid that are arranged on the edge and are therefore exposed, such as the holding projections, which are in any case more easily damaged or deformed due to the adjoining receptacles for the container edge. The above problems also arise correspondingly when handling isolated containers or when handling an isolated stripping grid. General be under "Stacked containers" always understood the container with the grid fixed on this in the transport position.

Furthermore, the top side of the lid is covered by the stripping grille arranged on the top side of the lid, so that, for example, damage to the lid or information carriers such as labels arranged on the top side of the lid are difficult to perceive.

The DE 20 2005 006 306 U1 , the U.S. 5,283,928 and the DE 10 2008 014 706 A1 describe generic containers with stripping grids, the stripping grids being provided with retaining projections and each being attachable to the side wall of a container.

The invention is based on the object of providing a container with a stripping grid or a stripping grid for such a container, in which the usability of the container with a stripping grid or the grid itself is improved, including improved protection of the scraping grid against damage during transport or handling of the container.

This object is achieved by a container with a wiping grid according to claim 1. Furthermore, the object is achieved by a stripping grid according to claim 14. Advantageous embodiments emerge from the subclaims.

The container with lid and stripping grid according to the invention is further developed in that the at least one retaining projection of the stripping grid (hereinafter also "grid") additionally has at least one severable connection to the stripping grid body at the level of the grid receptacle for the upper container edge, the Connection formed so that it can be severed while continuously fixing the respective holding projection on the stripping grid is. The connection is thus given in addition to the fastening area such as, for example, the molded area of the retaining projection on the stripping grille, which continuously fixes the retaining projection on the grating in the working position of the grating. The at least one connection of the body to the wiping grid is thus arranged at a distance from the end of the receptacle facing the body of the wiping grille (which end is opposite the receiving end on the grating edge). Due to the additional connection, the holding projection is additionally fixed in position with respect to the stripping grid body in the transport position of the grid. This has been found to be particularly advantageous because the receptacle for the upper container edge, which is directly adjacent to the respective retaining projection, otherwise only fixes the retaining projection with its end area to the grid body and the retaining projection can easily be changed or deformed in position relative to the body of the stripping grid, which is undesirable. since the retaining projection is mostly arranged on the edge of the grid and is also elongated due to the necessary longitudinal extension of the receptacle. Such a change in position or deformation, such as, for example, kinking, can impair the holding function of the holding projection in the working position of the stripping grid. These advantages arise in the case of stacked containers or bundles, but also in the handling of isolated containers.

Another advantage of the additional positional fixing of the holding projection according to the invention by means of the connection is that an undesired protrusion of the holding projection from its desired position, for example in the case of an isolated container, is avoided, which minimizes the risk of snagging with another object, especially also with isolated containers.

Another advantage of the additional connection is that the stripping grid can be demolded from an injection molding tool more easily and without damage, in particular the retaining projection.

Another advantage is that the additional position fixing of the retaining projection by means of the connection also stabilizes the retaining projection in the case of an isolated stripping grid, so that the isolated stripping grid can be safely handled before it is attached to the container side wall and stacks of stacked stripping grids are also stabilized.

The development according to the invention described above preferably applies accordingly to several or all of the retaining projections of the stripping grid.

If reference is made to “the retaining projection” or “the at least one retaining projection” in relation to a feature, this feature can apply to several or all of the retaining projections provided on the stripping grid. If reference is made to “the connection” or “the at least one connection” of a respective holding projection for a feature, this feature can apply to several or all of the connections of the respective holding projection. The same applies to other features according to the invention.

The terms “radial” and “axial” each relate to a direction radial and axial to the main axis of the container, which runs through the center of the container base and lid. With regard to the grid, these details relate to the transport position of the grid on the container or to the grid main axis which extends perpendicular to the grid main plane.

Becomes features related to the grid on the "container" With reference to this, this also specifically includes the cover.

In its first transport position, in which it is releasably fastened or can be fastened to the container or cover, the stripping grid is preferably arranged with an at least substantially parallel arrangement of the stripping grid and lid.

The respective at least one connection of the holding projection on the body, which is spaced apart and different from the permanent connection area of the holding projection with the body, preferably bridges the receptacle of the stripping grid for the upper container edge, so that the receptacle extends in the longitudinal direction of the receptacle on both sides of the severable connection .

The connection is preferably not limp. The connection is preferably pressure-stable and / or resistant to tensile force in relation to a manual pressure or tensile force of the holding projection on the grid body or away in the direction of the surface extension of the grid. This results in an advantageous stabilization of the position of the holding projection on the lattice body.

The respective connection of the holding projection to the body of the wiping grid is in each case preferably formed locally or at least essentially point-like, but optionally also linearly over at least part of the longitudinal extent of the receptacle.

In general, within the scope of the invention, the connection of the respective retaining projection to the body of the wiping grid can be carried out by a connection means such as an adhesive connection (e.g. by a hardening adhesive), an adhesive strip, a bridging element, which is fixed to the retaining projection on the one hand and the grating body on the other hand and bridges the receptacle of the grating for the container edge, or the like can be formed.

The "severing" of the connection can take place, for example, in the form of a cutting through or tearing through the same, possibly also in a broader sense such that, for example, a the bridging element forming the connection is released on one or both sides from its connection areas with the lattice body and / or holding projection or the bridging element is completely or partially removed. As a rule, according to the invention, with an existing connection, the container edge cannot be pushed into the grid receptacle up to its desired position in the working position; this is made possible after the connection has been severed.

In general, within the scope of the invention, the respective holding projection is preferably connected directly to the body of the stripping grid. If necessary, the connection to the body can also take place indirectly, for example on an intermediate element, provided the holding projection is additionally fixed in position with respect to the body of the wiping grid.

The connection is preferably formed by a material connection of a region of the retaining projection with the body of the stripping grille, for example by integrally molding, in particular when manufacturing the stripping grille as an injection molded component, possibly also by gluing or the like.

The severable connection is preferably designed so that it can be severed manually, particularly preferably without the need to use a tool for severing, but optionally also using such a tool.

The connection preferably has a weak point area in relation to the material thickness of the areas of the body and / or the holding projection adjoining the receptacle in order to facilitate the severing of the connection.

Preferably, several, for example two, connections spaced apart in the longitudinal direction of the container edge receptacle of the grid are provided with respect to the respective holding projection. This increases the positional stability of the holding projection in the transport position of the stripping grid or of an isolated grid. The connections can be separated by an opening or a material weakened area which is weaker or thinner than the connections themselves, in order to facilitate the severing of the connections. Furthermore, the connection areas of the holding projections can be designed as local projections which, when the grid is attached, result in a defined contact of the respective holding projection on the outer container wall.

Preferably, at least one or more of the additional connections of the respective retaining projection on the grid body are arranged radially outside a receiving area for an outside container flange, the container flange being at least partially encompassed or behind by the retaining projection when the grid is in the working position. This can relate to the container flange which is most axially spaced from the upper container edge. This container flange is usually also the container flange with the greatest width or radial extension from the container side wall. The stabilization of the retaining projection in the grid transport position or in the case of an isolated grid is hereby further improved, since the corresponding receiving area of the receiving element has a further greater width and is thus arranged radially inward to the connections. In addition, the mentioned connection areas of the holding projection in the grid working position can rest on the outside of the container side wall and stabilize the grid in its working position, as described below.

The at least one or all of the additional connections of the respective retaining projection are preferably arranged radially inward of a profiled grid edge area such as a U-shaped channel or edge-side grid flange, whereby the connections are protected by external forces acting on the edge area. Preferably at least one, several or all of the connections of the respective holding projection are covered by the bottom surface of a stacked container. If reference is made to a “stacked container”, this is generally understood within the scope of the invention, in particular, to be identical in construction to the container that supports it.

Generally preferred, in the working position of the stripping grid, the holding projection rests on the outside of the container side wall, at least in some areas, in order to provide a stable position of the stripping grid. In the lattice working position, the areas of the retaining projection that form the connection are particularly preferably in contact with the container side wall. As a result, a defined contact of the holding projections is provided even when the shape of the container changes, for example when the container is temporarily deformed, such as due to the application of force being applied to the wiping grid.

In its transport position, the stripping grid is preferably arranged on the upper side of the lid or is detachably attached to it.

In the transport position of the grid, the grid body is preferably at least substantially flat and is particularly preferably formed by a profiled edge area or the flange on the outer edge side, which in the transport position of the grid can lie against a profiled edge region of the cover, preferably linearly or flat. The stripping surface of the stripping grid and / or the installation surface of the grid for a stacked, structurally identical container (i.e. the area covered by the bottom of the stacked container) is preferably flat, in each case with reference to the grid transport position. The stripping surface of the grid is preferably part of the installation surface.

The at least one holding projection is preferably arranged in the extension surface or extension plane of the wiping grid body, based on the transport position of the wiping grid. The at least one holding projection is preferably formed in one piece on the lattice body.

The stripping grid preferably has at least or precisely two retaining projections in order to fix the stripping grid on the container. The holding projections can be arranged in relation to the width of the stripping grid in its working position at opposite end regions of the stripping grid, whereby a stable arrangement of the stripping grid is given in its working position on the container.

The at least one or the holding projections are each preferably arranged at the edge region of the wiping grid, wherein the holding projection (s) form part of the outer circumference of the wiping grid. The radial outer edge of the respective holding projection thus preferably represents part of the outer edge of the wiping grid. As a result, an arrangement of the respective holding projection on the outside of the container is in the working position of the The stripping grid is facilitated and the stripping surface of the stripping grid arranged between the holding projections is enlarged. It goes without saying that with this design of the holding projection the additional connection (s) according to the invention between the holding projection and the lattice body are particularly advantageous, since on the other hand the holding projection can easily be acted upon by radially external forces.

The radially outer edge region of the holding projection can be profiled, whereby it is stabilized, the profiling can at least essentially correspond to the profiling of the edge region of the lattice body, but possibly also be designed differently. The retaining projection can thus functionally be part of the grid edge, in particular with reference to the transport position of the grid. The radially outer edge area of the holding projection can represent a preferably structurally identical continuation of the profiled edge area of the lattice body, so that the holding projection is formed by introducing the receptacle into the lattice body. The profiled edge area of the holding projection can, as a sub-area of the grid edge, grip laterally around a stacked container and limit its footprint. Alternatively or in addition, the holding projection can provide part of the installation surface of the grid for a stacked container, so that the stacked container is seated on an area of the holding projection. It follows from this that corresponding forces can act on the holding projection as they do on the grid body edge area, which results in the advantages according to the invention in a special way.

The grid body edge and the radially outer edge area of the retaining projection can be profiled in the form of a U-shaped channel which has an upper Can accommodate the edge region of the cover at least partially or at least substantially completely. At the same time or independently of this, the lid edge area can be designed as a U-shaped channel which can accommodate the upper container edge and can be fixed to it with latching means. The U-shaped channel of the stripping grid can be constructed at least essentially identical to the U-shaped channel of the cover, but possibly also different from this. The U-shaped channel of the stripping grid can have the width of the U-shaped channel of the cover, so that in the transport position of the grid the channel of the cover is at least partially or completely received in the channel of the grid. In this case, the radially outer flange of the channel of the grid partially or completely covers the radially outer flange of the cover channel, correspondingly for the radially inner flange of the U-shaped channels of the grid and cover. As a result, the edge area of the grid is stabilized laterally by the lid edge.

The edge area of the retaining projection can thus project beyond the base of the U-shaped channel of the cover radially on the outside and thus represent a partial area of the outer edge of the component group of grille and cover. This creates an additional risk of undesired attack on the holding projection, for example when handling the container. In this embodiment, too, the further development according to the invention with additional connections of the retaining projections has proven particularly useful.

In the context of the invention, the U-shaped grooves of the grid and lid are generally open towards the container bottom of the container, based on the transport position of the grid and the lid closing the container.

The grid receptacle for the container edge when the grid is attached to the grid edge side can have a certain circumferential extent to take into account the arrangement of the grid in its working position on the container edge, whereby an external lateral attack on the free end of the retaining projection is additionally facilitated. Here, too, the design of the retaining projection according to the invention with the additional connections has proven particularly useful.

The circumferential lid edge can have a constriction radially on the outside, which can accommodate an outer flange of the grid, which extends towards the container bottom, whereby a radial protrusion of the grid flange can be avoided from the lid edge and the grid flange is thus protected.
The receptacle preferably has at least one projection protruding into the receptacle at a distance from its end on the inside of the grille, which in the working position of the stripping grid engages under a flange or protruding edge arranged on the outside of the container, which preferably extends around the circumference of the container. As a result, the grid is stabilized in its working position, in particular with regard to vertical displacements and tilting as can occur when the coating composition is stripped from the tool.

Particularly preferably, the aforementioned projection is arranged on the end area on the inside of the grid and / or in the middle area of the receptacle, whereby the grid is fixed in its working position in relation to the container height in the area of the upper container edge and / or at a vertical distance therefrom on the container. The arrangement of the projection on the end area of the receptacle on the inside of the grid has changed particularly well-proven, since in this way already incipient changes in the position of the grid can be effectively prevented or reduced, also taking into account leverage in relation to the grid placed on the upper edge of the container. The flange or edge region of the container which this projection engages behind preferably has a latching edge for fixing the lid. The projection arranged in the central receiving area can reach under a container flange which has a greater radial extent than the flange or circumferential edge arranged on the container edge. In particular, a combination of the above-mentioned projections has proven to be particularly effective, since as a result the holding projection is effectively secured in position on the container side wall at points spaced apart from one another and thus the grid in its working position.

The respective projection of the receptacle is particularly preferably designed in the shape of a hook, so that it engages behind, for example, an undercut area of a flange or protruding edge of the container outside in the working position of the grid, whereby the corresponding grid area is effectively fixed in position against radial spacing from the container outside when the tool is stripped. As a result, the grid is effectively secured in this area against spacing from the container and also against tilting, which has been found to be particularly position-stabilizing when the tool is applied. The container flange under which it engages is preferably that which has the greatest radial extent from the container side wall or which is the flange which is the greatest distance in the container height from the upper container edge.

The retaining projection preferably has at the level of the stripping surface on its facing towards the receptacle Edge area a stiffener, for example in the form of a molded rib. As a result, the retaining projection is particularly stabilized and thus also the fixing of the stripping grid on the container wall in its working position. The reinforcement can extend in particular in the area of the holding projection which engages under a container flange, in particular the one with the greatest radial extent starting from the container side wall, whereby the stripping grid is particularly stabilized in its working position.

A particular embodiment of the container according to the invention is given by the features of claim 7. The arrangement of the stripping grid on the cover is stabilized by the securing projections according to claim 7, in particular when lateral force is exerted on the stripping grid. As a result, the grille is particularly secured against displacement at the edge and other fastening areas between the grille and cover are relieved and undesired detachment of the grille from the cover is made more difficult. This applies to isolated and / or stacked containers. The securing projections can be arranged in the radial direction with a certain amount of play in relation to the radially inner and / or radially outer regions of the cover which are immediately adjacent and which protrude in height.

When the grid is fixed in its transport position, the securing projections are preferably supported on the cover on the top side of the cover. In general, the securing projections are preferably not designed as latching projections and / or are fixed on the cover in a clamping manner. The Securing projections are preferably designed as webs which can extend over a partial circumference of the container.

Particularly preferably, the circumferential U-shaped channel of the cover has a stepped shoulder, the securing projections of the stripping grid being supported on the stepped shoulder. Due to the increased stability of the step shoulder due to the given profile formation, a particularly stable support area is provided.

Particularly preferably, the upwardly protruding areas of the lid, which at least partially overhang the height of the securing protrusions of the scraper grille, form an upwardly open channel which extends at least over part of the container circumference and thus surrounds the securing protrusions radially on the inside and radially on the outside .

Particularly preferably, the upwardly projecting areas of the cover, which at least partially transfer the height of the securing projections of the wiping grid, are molded onto the circumferential U-shaped channel of the cover. As a result, the edge area of the cover is additionally stabilized, an arrangement of the securing projections on the edge side with the advantages mentioned above also being given.

The securing protrusions are preferably arranged in the circumferential direction of the container adjacent to the securing protrusions between the stripping grid and cover, for example at a distance less than or equal to twice or less than or equal to the circumferential extent of the securing protrusion adjacent to the given securing protrusion. Here is one special stabilization of the grid against lateral forces given by the interaction of the support and fastening projections.

A plurality of securing projections distributed over the circumference of the container are preferably provided. A securing projection is preferably arranged in each case adjacent to a pair of corresponding fastening projections of the cover and the stripping grid. The securing projections are preferably arranged at a distance from the corner regions of the container in the circumferential direction. The securing projections are preferably arranged in the respective central region of a side wall of the container. If necessary, instead of a plurality of securing projections arranged distributed over the circumference of the container, a securing projection extending completely around the circumference of the container can also be provided.

Said securing projections of the stripping grid can additionally also serve as stacking projections which, when the stripping grids are stacked on top of one another, are supported on the respective grids arranged below and stabilize the stack.

An independent embodiment of the container according to the invention is also given by the container according to claim 11, the characterizing features of which, however, are preferably implemented in combination with any other container or container with a lid according to the invention.

The upper side of the cover is partially visible due to the design of the stripping grid at least partially or completely from a transparent material. This makes the stripping grid of the container lid, which is preferably made of a non-transparent material, optically lifted off and the manual handling of the scraper grid when loosening the lid is easier. The material of the stripping grid can be designed to be clear, opaque or translucent.

The wiping surface of the wiping grid for the application tool preferably consists at least partially or completely of a transparent material, whereby the preferably at least essentially flat inner lid surface is visible when the container is viewed from above. Due to the optical differences between the preferably non-transparent cover and the wiping grille, the grille is easily recognizable and therefore easy to handle. The stripping surface is preferably delimited on the outside by the circumferential cover edge, which is generally designed as a flange or as a U-shaped channel.

In combination with the at least partially or completely transparent design of the stripping grid or the stripping surface of the same, the cover is preferably provided with an information carrier at the level of the aforementioned transparent area. This increases the functionality of the container. It goes without saying that the information carrier or a partial area which represents the respective information is preferably designed to be non-transparent. The information carrier can be designed as a label, label, in particular in-mold label, for example. Preferably, any fastening projections provided by the cover and the stripping grid on one another and / or the securing projections on the stripping grid on the cover are arranged radially outside the information carrier attached to the cover. This makes it easier to attach the information carrier to the cover and avoids damage to the information carrier by the named projections when fixing the stripping grid on the cover.

The grid and cover can be detachably fixed to one another by means of fastening projections, preferably non-positively and / or positively.

Preferably, the grid is detachably fixed to the cover by means of at least one or more fastening means with plastic deformation of the same / the same. The fastening means can be arranged on the grid and / or cover, preferably on the cover. The fastening means is particularly preferably molded in one piece on the respective component, in particular on the cover. The fastening means can in each case be designed as a fastening projection which engages in a receptacle on the corresponding component of the grille or cover, the receptacle preferably being completely closed. The receptacle can also be designed as a projection or also as an opening in the respective component. A particular advantage of this embodiment is that it allows greater tolerances of fit between the grille and cover, while achieving a particularly captive fastening of the grille to the cover. Thus, the fastening means to be plastically deformed for fixing can engage with a comparatively large amount of play in the corresponding receptacle (prior to the deformation process) and the grille can still be securely fixed on the cover by the plastic deformation of the same. The plastic deformation for fixing the components can partially or completely cancel out said play, so that the grille and cover are additionally secured laterally to one another by the fastening means at the same time, which is advantageous with the comparatively flexible grille. This configuration is special It is advantageous if the lid is made of different materials over the extension of the lid surface, e.g. is provided with a label such as an in-mold label on the top of the lid - it has been shown that the lid then has a different dimensional accuracy, especially in injection molding processes, due to the manufacturing process than with production from just one material such as without an in-mold label. It has been found that this can result in fitting problems which make it more difficult to reliably secure the grille and cover, for example by means of corresponding latching means, in particular when the two components are mechanically latched with rapid timing. This problem is eliminated by the fastening means described. In addition, the plastically deformed fastening means secures the grille on the cover in a particularly captive manner, since it has been found that, for example, when the fastening means are designed as latching means, the latching means can undesirably loosen when the force is applied from the side, such as when containers hit the side. The plastically deformed fastening means can fix the grid in a form-fitting manner, optionally also in a force-fitting or material-fitting manner.

The fastening means plastically deformed for fixing can be designed in such a way that the grid can be removed from the cover by manual exertion of force on it, in particular by exerting tensile force, that is to say the fastening means is overcome. This takes place preferably only with deformation of the fastening means, that is to say without material separation of a part of the fastening means. If necessary, the grating can be separated with the aid of tools. If necessary, said fastening means can also be designed so that they are used to separate the grid by destructively tearing off a Part of the same are to be overcome, for which purpose a material weakening that facilitates tearing off, such as, for example, constriction, can be provided.

The fastening means, which are plastically deformed to fix the grid, are preferably designed such that, when the fastening means are actuated, the separated grid can again be fixed to the cover, for example non-positively or positively, in particular by pressing the grid onto the cover. If necessary, however, the grille is only fixed to the cover once.

The plastic deformation of the fastening means for fixing the grid is preferably carried out by hot forming such as, for example, by hot riveting.

The plastically deformable fastening means is preferably designed as a rivet, for example as a hollow rivet. The rivet can engage in a receptacle of the corresponding component of the cover or grid, preferably the grid, and can be expanded in this arrangement to fix the grid. If necessary, said fastening means can also be designed as a tab or the like which, while deforming, encompasses or encompasses a sub-area of the corresponding component of the cover or grille, in particular the grille.

The receptacle for the plastically deformable fastening means can have a reinforced edge area, for example in the form of a hollow pin.

Said container with plastically deformed fastening means for fixing the grid can have the further features of a container according to the invention or a container with a lid individually or in combination.

The Figures 1-6 show a container according to the invention consisting of container 1 with container main axis A, lid 20 and stripping grid 30, the stripping grid and / or grid with lid also being disclosed separately.

The container 1 has a container opening 4 for removing the container contents, such as a coating composition, and a circumferential side wall 5. The cover 20 can be fixed to the container side wall 5 in a sealing manner, for example by means of corresponding latching projections. The wiping grid 30 has an at least substantially flat body 31 and a central stripping surface 32 for stripping the coating composition from an application tool. The grille is in a first transport position ( Fig. 5 ) detachably attached to the lid 20, with at least an essentially parallel arrangement of the stripping grille 30 and lid 20. The grille can be positioned in a working position with the container 1 open in an arrangement attached to the container side wall 5 ( Fig. 1 ), allowing the application tool to be introduced into the container, a portion of the grating 30 or the stripping surface 32 of the same protruding upward from the container opening. The grid has several (here two) receptacles 34 opening into the peripheral edge 33 of the same for the container side wall for attaching the same onto the container side wall. The receptacle 34 laterally delimits a holding projection 35 in the direction of the stripping surface, the holding projection being arranged outside the container when the grid is attached and resting on the outside of the side wall 5.

The holding projections 35 each have at least one connection 36 on the grille body 31 at the level of the receptacle 34, with the respective holding projection on the stripping grille being continuously fixed via the connection area 37. According to the example, the respective holding projection 35 has two connections 36 at the level of the receptacle 34 with the lattice body 31, which are spaced from one another in the receiving longitudinal direction and separated from one another by an opening 38. The connection areas 39 of the grid that merge into the connections 36 are in contact with the outside of the container side wall 5 when the grid is arranged in its working position and thereby form a defined system ( Fig. 2 ). The connections 36 are each formed by integrally molding the respective retaining projection 35 on the grid body 31 designed and provided with a weak point area to facilitate the severing. The connections or connection areas are designed to be pressure and tensile force stable, at least with respect to manual attack.

The receptacle has at a distance from its end on the inside of the grille, here in its end area on the inside of the grille and in its central area, two projections 39a, 39b protruding into the receptacle, which in the working position of the stripping grille each engage under a flange 6a, 6b arranged on the outside of the container 1, whereby a stable working position of the grid is given. The flange 6a here has a circumferential latching projection for fixing the cover 20. The projection 39b is hook-shaped and engages under the flange 6b ( Fig. 2 ), whereby the grid is secured in this area against lateral spacing from the container side wall, in particular also when the grid is applied with the application tool.

The holding projection 35 has a reinforcement 40 at the level of the stripping surface 32 on its edge region facing the receptacle 34, here in the form of a rib.

At its edge area, the lid 20 has a circumferential, U-shaped channel 21 which, when the lid is fixed to the container, receives the upper edge 7 of the container. The U-shaped channel 21 has an upper edge region 21a and, radially inwardly of this, a circumferential cover flange 21b adjoining this and sloping down towards the container bottom and an outer flange 21c.

The grille 30 is provided at its edge area with a circumferential, U-shaped channel 41, which here preferably at least partially or substantially completely receives the U-shaped channel 21 of the cover, so that the channel flanges 22b, 22c of the mesh cable tray cover the respective adjacent cover channel flanges 21b, 21c at least essentially completely in the radial direction.

The radially outer cover flange 21c has a constriction 23 for receiving the outer grid flange 41c, so that it does not protrude radially from the cover edge and is thereby protected.

Cover 20 and stripping grille 30 have fastening projections 22, 42 that correspond to one another for secure attachment of the grille to the cover in its transport position, which are designed here as latching projections, possibly also as a clamp connection. In a special embodiment, the fastening projection of the cover and / or the fastening projection of the wiping grid are supported on the respective other component of the cover and the wiping grid. In particular, the fastening projection 42 of the grid is supported here on the lid or the top side of the lid, so that a defined force transmission is provided when the containers are stacked. The fastening projection 22, 42 of the cover or grid is preferably designed as a hollow cylinder with an inside undercut, in which the corresponding fastening projection of the other named component engages, whereby these are laterally secured against displacement on all sides when lateral forces act on the grid relative to the cover. Any other areas where the grille and cover are attached to one another are relieved of pressure.

The fastening projections 22, 42 of the grid and cover are arranged in the radial direction at the level of the edge area of a stacked container, so that through stacked containers, the fastening projections are particularly secured in position on each other.

The fastening projections 22, 42 of the grid and cover are radially inside, here adjacent, to a circumferential, U-shaped channel 21, 41 of the cover or grid, the U-shaped channels generally provided within the scope of the invention on the cover and grid could be. As a result, the sealing area of the lid on the container is not impaired and, due to the possible dimensioning of the fastening projections, a secure fixing of the grille on the lid is made possible. An information carrier arranged on the top of the cover can be arranged at a distance from the fastening projections and can be large.

The fastening projections 42 of the grid are arranged distributed over the grid surface and secure the grid in a torsion-proof manner (against rotation about the main axis of the container) on the lid. According to the example, four such fastening projections are provided in a rectangular arrangement.

The above statements regarding the fastening projections 22, 42 can generally apply within the scope of the invention.

On the underside of the grille 30, downwardly protruding securing projections 43 are provided ( Fig. 6 ), which are arranged in the radial direction between the outer circumferential cover flange 21c of the U-shaped channel and upwardly extending projecting cover areas 24, each of which at least partially protrudes over the securing projections 43 Abstreifgitter in height. This applies to isolated and / or stacked containers. As a result, the edge area of the grid is additionally secured against lateral displacement. Of the Cover flange 21c and the upwardly projecting cover areas 24 can form an upwardly open channel which receives the securing projections 43, optionally with radial play in relation to these. The upwardly protruding cover areas 24 can each be designed as a partially circumferential or coherent bead of the cover that runs around the entire circumference, the bead can form a groove of the cover profile that is open below. The securing projections 43 can be supported on the top of the cover when the grid is fixed to the cover. The securing projections 43 are arranged in the area of the fastening projections 22, 42 in relation to the circumferential extent of the container.

It should be noted that in Fig. 6 the grid is shown only loosely placed on the cover, in the transport position of the grid, the securing projections engage in the groove of the bead 24 and the flange area 25 of the cover.

The circumferential U-shaped channel 21 of the cover can have a stepped shoulder, the securing projections 43 of the grid being supported on the stepped shoulder. The upwardly projecting regions of the cover 24 can generally be formed on the circumferential U-shaped channel of the cover or on a stepped shoulder of the same.

The grille 30 is made entirely of a transparent material, thus also the stripping surface 32 of the grille. The top of the cover 20 is provided with an information carrier 45 such as a label, in-mold label or the like (not shown) at the level of the grid area made of transparent material, which is thus visible through the grid. The fastening projections 22, 42 of the cover and grid on one another are radially outside of the information carrier attached to the cover arranged, whereby the attachment of the information carrier to the cover is made much easier.

The portion of the lattice stripping surface 32 protruding into the container is provided with perforations 46 distributed over them, the part of the stripping surface protruding from the container being free of openings at least over an area of ≥ 30% or ≥ 50% or preferably ≥ 75%. As a result, on the one hand, the coating composition applied to the grid part protruding above the container is safely transferred to the interior of the container. On the other hand, the lower area of the grid between the holding projections can be deformed more easily, as a result of which the grid can be more easily adapted to the container circumference when it is placed on the container and also facilitates drainage of the coating composition.

The Figures 7 and 8th show an alternative fastening of the grid on the cover, which can generally be implemented within the scope of the invention. The grid 30 is fixed to the cover 20 by means of at least one, here several, plastically deformed fastening means 47. The fastening means 47 is integrally formed on the cover 20 and positioned in a receptacle 48 of the grille. The fastening means 47 is designed as a rivet, in particular a hollow rivet. The lattice receptacle 48 is provided with a hollow pin 48a or, in general, preferably with a circumferential collar for reinforcement, but if necessary the plastically deformable fastening means 47 can also generally be fixed on the edge of a receptacle. When the grid 30 is placed on the cover 20 before the fastening means 47 are fixed, the free end of the hollow peg 48a sits on the top of the cover without this always being mandatory.

Figure 7 shows the fastener 47 prior to its plastic deformation. The fastening means has a radial play for the receptacle 48 over its entire circumference, which can be, for example, in the area of the wall thickness of the hollow pin. This play can compensate for comparatively high fit tolerances between the grid and cover in the area of the fastening means. This is particularly advantageous when arranging an in-mold label on the top side of the lid, which influences the dimensional accuracy and shrinkage behavior of the lid when it is manufactured using the injection molding process. As a result, the label can have a large area, for example extending over ≥ 25% or 50% of the cover area.

Figure 8 shows the plastically deformed fastening means 47, which fixes the grid in a form-fitting manner. The fastening means is widened at least in the area of its free end, for example by hot forming, and rests against the grating receptacle 48 without play. In order to facilitate the form fit of the reshaped fastening means, the receptacle 48 has a preferably encircling inner shoulder 48b. The fastening means ends flush with the top side of the grid 30a or is set back in relation to the cover; under certain circumstances the deformed area of the fastening means can also rest against the top side of the grid.

If necessary, another plastically deformable fastening means can be used instead of a hollow pin, such as a pin that is to be deformed like a head at its free end, for example as a solid pin, a plastically deformable or plastically bent tab or the like, the rivet design of the fastening means shown particularly proving itself Has. Possibly other openings in the grid can also function as a fastening means receptacle.

The receiving area 48 or the hollow pin 48a has a bevel 48c at its free end on the inner edge side, in order to enable the grille to be fixed to the cover again in a non-positive and / or positive manner after the grille has been separated from the cover.

With regard to the arrangement of the fastening means 47 on the cover 20, what has been said about the fastening projections can generally apply, see, for example. Figures 1-5 .

Further features of the container according to the invention with a grid or the grid can be found in the figures.
