Description

The invention relates to a generic type of a container, comprising a lid and a container inner space having a vertical height, and an insert arranged in the container inner space, as defined in the generic part of claim 1.

Containers are filled with various kinds of materials, partly also with materials that include volatile components, with filling materials having dynamic properties accompanied by volume changes such as thixotropic properties etc. Such a filling material is for example emulsion bitumen, i.e. a bitumen emulsion that is mostly water-based. However, filling such materials is in no way trivial, as it might appear to be at the first sight.

For instance, for technical reasons of filling, there frequently exists a free space above the filling material. The result is that when filling material such as emulsion bitumen is stored in the container, volatile components of the emulsion bitumen accumulate in this free space. This negatively influences the composition of the filling material, and in the case of emulsion bitumen this leads to an increase of its viscosity, up to skinning on the surface, whereby proper processing is made more difficult or the quality requirements are not met. For this reason, the surface of the bitumen emulsion filled into the container is frequently covered with a film. This film must be very carefully adapted to the inner contour of the container wall in a manual process, which is time-consuming and often carried out only insufficiently. This consequently leads to undesired skinning or other modifications of the filling material in these areas, although such skinning or other modifications of the filling material should be avoided in order to produce the respective object, e.g. a roof covering, in a professional manner. Particular filling materials may additionally require the arrangement of an insert in the container inner space, which receives for example a hardening composition to be processed together with the filling material, wherein said insert is attached to an inwardly curved peripheral bead of the container. The insert consists of metal just as the container. However, filling the container using the working steps as described is very time-consuming and expensive.

Additionally, care must be taken that containers with filling materials which comprise volatile components can be quickly and securely filled in a filling plant, while an amount of volatile components discharged by the filling material to the free space of the interior of the container provided above the filling material should be as small as possible. This also applies in a case where the filling level of the filling material, especially emulsion bitumen, changes after the container has been correctly filled, e.g. when the filling material settles or deposits or shrinks as a result of its dynamic properties, for example thixotropic properties etc. For this reason, the volume of emulsion bitumen freshly filled into the container is larger than after a certain storage time, i.e. when the filling material has reached its final filling level (for the same weight). It shall be ensured even under such circumstances that the filling material, especially emulsion bitumen, is not undesirably modified on the surface thereof, particularly by skinning, upon storage in the container. However, especially in a filling process carried out in a filling plant, the method which is presently used and which involves manually applying a film and arranging the insert with the hardener in the upper space of the container, is extremely time-consuming and costly.

The document US 2007/0215624 A1 discloses a container with a lid and with an insert, wherein the insert has an outer rim that matches the inner periphery of the container for sealing against the container. By means of ribs disposed on the inner side of the container, said insert can be arranged at various levels in the container.

The document GB 2306429 A discloses a container with a lid and with an insert, wherein said insert consists of a flexible material and can be positioned at various levels on the inner wall of the container.

The document US 2004/0226955 A1 discloses an insert for covering a filling material surface in a container, wherein the insert has a peripheral flange that is articulated to the body of the insert, wherein a peripheral edge of the flange can bear against the inner wall of the container.

The document DE 10 2006 041351 A1 discloses an airtight lid having a reversing membrane, which lid is vertically adjustable in said container.

The document DE 847678 discloses a preserving jar having a cover arrangement, wherein the jar inner wall has inwardly protruding stoppers for securing the cover arrangement against displacement in the vertical direction.

The invention is based on the problem of providing a container with a lid and with an insert of the type described, which particularly allows the storage of emulsion bitumen or similar materials, which settle after filling and change their filling level (for the same filling weight) and which may have surface-sensitive properties, in a manner such that a modification of the surface of the filling material is avoided as far as possible, even in case of different filling levels of the container and rapid processing of the filling material, and wherein the insert remains stable even when an object with a large weight is placed into the insert.

According to the invention, this problem is solved by the subject according to claim 1. By securing the fixing area of the insert radially inwardly using securing means, it is prevented that the fixing area disengages from a corresponding fixing area of the container inner wall and that the insert becomes instable when a heavy object such as a hardener component, a processing device etc. is placed into the container, resulting in that the insert is for example tilted and deformed so that the weight can get into the filling material.

Preferred embodiments of the invention will become apparent from the subclaims.

Preferably, the securing means engage on a projection of the insert in a securing manner.

Preferably, the securing means are constructed as projection which engages in a recess of the insert in a securing manner, or a recess is provided by the securing means which is engaged by a projection of the insert in a securing manner.

By the design of the container with lid in which an insert is arranged in the container inner space which divides the container inner space into a lower and an upper part and which (1) is arranged in a vertically adjustable manner in the container inner space and/or (2) is adapted with its rim portion to the peripheral contour of the container inner space and sealingly separates the container inner space into a lower and an upper part, and in which the insert is fixed or can be fixed to the wall of the container at a predetermined level in the container inner space, the container inner space existing above the filling material can be separated from the filling material by said insert which is preferably fitted to the peripheral contour of the container inner space, and the separation can be carried out in a sealing manner against the container inner wall such that volatile components of the filling material are prevented from escaping to the container inner space and undesired modifications of the filling material on the surface thereof such as skinning are prevented by said insert, at least as far as possible. Placing a separate film onto the surface of the filling material can thus be completely omitted. This is already achieved by the insert being lowerable until it reaches the surface of the filling material and thus directly covers the surface of the filling material, whereby a volatilization of components or curing thereof in the air or a superficial oxidation are avoided. By adapting the insert to the peripheral contour of the container inner space, the outer rim of the insert can bear against the inner wall of the container so as to be sealed around the entire circumference and/or can be clamped to or secured on the inner wall of the container. The outer rim of the insert, which can be designed as a sealing area, is preferably uniformly applied against the inner wall of the container around the entire circumference, particularly preferably with a uniform pressing force and/or with a uniform geometrical design regarding the profile of the contact area. Irregularities in the sealing area or in the contact area of the outer rim of the insert with the inner wall of the container, especially distortions of material such as for instance corrugations of the rim area of the insert, which may cause leaks, are reliably avoided. Accordingly, the form of the outer rim or sealing area of the insert preferably matches the cross sectional shape of the container inner wall at a level of the container which may be the filling level of the filling material (this refers to a case where the insert then rests with its bottom on the filling material) or may be spaced by the height of a skirt provided on the insert. This can refer to the filling material just filled in or preferably to the filling material that has settled.

The outer rim of the insert can be congruent with the cross sectional shape of the container inner wall at least at a level of the container, hence even without a deformation such as a compression or elongation of the rim area. The outer rim of the insert can be congruent with the cross sectional shape of the container inner wall when the insert, at least the bottom area thereof, is arranged at the level of the filling material. This may respectively apply to the sealing area of the insert and to the corresponding contact area of the container.

The peripheral outer rim of the sealing area of the insert is preferably arranged in a plane that is perpendicular to the main axis or longitudinal direction of the container when the insert is installed. The bottom or central portion of the insert is preferably planar, the bottom side thereof (facing the filling material) can be smooth and free of any protrusions. The bottom of the insert is preferably continuous and without breakthroughs. This preferably refers to the region of the insert which when installed is arranged at or lower than the level of a sealing area of the insert against the container inner wall.

Particularly preferably, the insert has an inherent stiffness such that it is dimensionally stable when subject to the influence of gravity under its own weight. Thus the insert is easy to handle and can particularly be contacted with the container inner wall inside the container over the entire circumference and/or can be vertically displaced in the container, e.g. for being placed onto the top of the filling material. This particular level can be the level of the filling material, which then corresponds to the level of the bottom of the insert. This enables a reliable separation between the upper and lower space in the interior of the container in a simple manner, while the insert may nevertheless present a certain degree of flexibility upon exertion of a manual force. For example, the rim of the insert can be elastically deformable, particularly under conditions existing when the insert is in downwardly introduced into the container in a vertical direction.

Accordingly, the insert can be constructed and adapted to the peripheral contour of the container inner wall in such a manner that by introducing the insert in a vertical direction, the same will find a seat on the container inner wall at a vertical level, while the insert can be freely suspended in the inner space of the container without being supported (e.g. by the filling material) and while being sealed against the inner wall of the container over the entire circumference and/or without deformation of the rim area of the insert. This can be the case with a container, which is filled or not. Preferably, this is the case with the insert engaging the upper edge of the container. Accordingly, the insert can be fixed exclusively against the inner side of the container. Preferably, the insert can be vertically displaced by a certain amount to a second position (at a lower level in the container) in which the insert also bears against the inner wall of the container (preferably around the entire circumference). In the first and second vertical positions and during its displacement between these two positions, the insert can be permanently sealed against the inner wall of the container.

Preferably, in the container according to the invention, the insert in its desired position is arranged below the lid, especially when it is supported on the filling material such that the insert does not touch the rim area of lid or the entire lid when the lid is attached as intended. This may apply to an isolated container or also to a container stacked with other containers. Generally, the insert can be sealingly applied against the inner wall of the container and/or can be fixed against that wall in a manner spaced from the upper edge of the container. Thus the container/lid assembly can be selectively used with or without insert and can be sealingly closed as intended, particularly without changing the sealing and/or fixing area of the lid against the container. The level for the arrangement of the insert inside the container can thus be easily adjusted to the filling level of the filling material even with different filling volumes. In this manner, the insert is designed so as to be vertically adjustable with respect to the inner wall of the container, while it preferably remains sealed against the container inner wall at different levels and over the entire circumference.

Particularly preferably, the insert is designed in such a way that it can be vertically displaced by > 0.3 cm or > 0.5-0.75 cm, preferably by >1.1-1.6 cm or > 2.3 cm, for example > 4.5 cm, if necessary < 10-15 cm or < 20 cm, while bearing against the inner wall of the container. This enables the position of the insert being adapted to the actual filling level in order to minimize the free space between the filling material and the insert, even if the filling material settles after being filled into the container, i.e. the filling level is reduced without removing filling material. During this height offset, the insert can remain permanently sealed against the inner wall of the container. The region of the inner wall of the container over whose height the insert can be vertically displaced while being preferably sealed against the wall, is preferably free of any radial offset or step and preferably tapers under a cone angle which at least substantially constant towards the bottom of the container. The container wall can be at an angle (particularly a cone angle) of > 0.1-0.2 degrees or > 0.5-1 degree or also > 2-3 degrees or > 5-10 degrees to the container main axis 8, preferably an angle of < 20-30 degrees or <10-15 degrees or < 4-7 degrees, which can generally apply within the scope of the present invention. The cone angle of the container can be circumferentially uniform, at least substantially. Preferably, the container can be stacked inside identical containers.

Preferably, the insert is adapted to the cross sectional shape of the inner wall of the container at a level of the container and is congruent with the peripheral contour thereof, which is spaced from the upper edge of the container by < 20-25% or < 10-15% or < 5% or only < 2-3.5% in relation to the height of the container. The level of the container at which the insert is adapted to the inner wall of the container, can be spaced from the upper edge of the container by > 1 to 2% or > 3 to 4%, where necessary also by > 5 to 10%.

Preferably, the outer rim of the insert has a flange at least partially extending in the vertical direction, which can be designed for instance as a raised rim of the insert. A portion of the flange can provide a sealing area of the insert against the inner wall of the container, preferably a portion of the flange that is vertically spaced from the central (middle) region or bottom of the insert and that is preferably arranged above the bottom of the insert. This enables the outer rim of the insert being adapted to the inner wall of the container, even if the insert is arranged at different levels in the container. A certain deformation of the sealing area of the insert is thus possible, without an (excessively strong) deformation of the flange and/or the bottom of the insert when the insert is inserted in the container at a position lower than the position in which the sealing area is congruent with the peripheral contour of the inner wall of the container.

The sealing area of the insert can be elastically deformable, e.g. in the form of a protruding sealing lip that can be arranged on a body or flange of the insert. The thickness of the material of the sealing lip can be clearly smaller than that of the bottom of the insert and can amount to e.g. < 25-50% or < 10-25% of the same. The sealing lip or generally the sealing area can simultaneously be designed as a clamping member for fixing the insert against the inner wall of the container and can have a sufficient rigidity for that purpose, particularly when the insert is merely loaded by its own weight. The sealing area can also be designed so as to be deformable by compression, e.g. in the form of a foamed material. The sealing element is preferably integrally molded to the insert such that it will not become detached upon a vertical displacement of the insert.

The rim portion of the insert can generally be designed in such a manner that it presents a smaller frictional or clamping force against the inner wall of the container than the cohesion of the insert against the filling material when the insert is seated on top of the filling material. Upon shrinkage of the filling material, the insert can automatically withdraw into the interior of the container together the surface of the filling material such that no additional pressure must be exerted either manually or by means of a pressure-exerting element.

Generally within the scope of the present invention, the sealing area of the insert which bears against the inner wall of the container can have a higher degree of flexibility than a part of the insert (to which the sealing area can be directly molded) arranged radially inwardly with respect to said sealing area such as for instance a body or the flange of the insert or a region which can stabilize the flange and/or the bottom of the insert, such as a stepped shoulder, a region provided with a reinforcing rib, a thick point region or the like. The central area of the insert, e.g. in the region of the container main axis, can in turn have a higher degree of flexibility than the reinforcing region.

According to a further advantageous embodiment, the insert is or can be fixed to the inner wall of the container at a predetermined level in the container inner space. To this end, the insert and/or the container inner wall can comprise at least two projections, which each extend towards and engage at the respective other component (i.e. the insert or the container wall) so that the insert is or can be supported against the container at a predefined level by means of the projections. There can be arranged for example three, four or more projections on the insert and/or container wall, which are distributed over the circumference of the insert and/or container wall. Preferably, these projections are arranged in the corner areas of the container. Where appropriate, also only two projections can be provided which then have a larger horizontal extent, e.g. over more than half the entire width or over approximately the entire width of the container wall, wherein these projections can be opposed to each other on the insert and/or on the container wall. In particular, said projections can be constructed in a web- or stripshaped manner. Preferably, said projections are arranged on at least four container wall areas that can be opposed to each other in pairs, and/or on the corner areas or the areas of the container having the larger curvature. Where appropriate, the insert can also comprise a peripheral protrusion or shoulder that is supported by a part of the container wall, or the insert comprises a peripheral rim that is placed onto an inward shoulder of the container wall. In this case, the peripheral rim of the insert can be regarded as a peripheral protrusion, which also comprises at least two projecting regions for fixing the insert at predetermined level. Fixing the insert to the container wall at a defined level prevents the insert or the weight arranged in the insert from sinking into the filling material even if a weight is arranged in the insert, e.g. a hardener or a processing device, and even under unfavorable transport conditions, e.g. when carrying the container while the container is not horizontally oriented. Said projections accordingly prevent that the insert will tip over inside the container, in which case the inserted weight could be immersed into the filling material. Alternatively, though less preferred, also several radially inwardly protruding and circumferentially spaced projections or shoulders (or a respective radially inwardly protruding peripheral projection or shoulder) can be provided, where the insert can be placed on such that the insert itself needs not be provided with projections. However, this embodiment is less preferred from the technical aspect of molding and from the aspect of handling.

Particularly preferably, the container wall comprises at least two, three, four or more outwardly bulging indentations which are engaged by projections arranged on the insert and which can thus support the insert at a defined level against the container wall. The indentations can be designed in a pocket-shaped manner. The indentations can expand the container inner space radially outwards. Due to these indentations on the container wall, unhindered homogenization of the filling material by appropriate tools such as a stirring tool is possible as before. Further, the insert can be securely supported against the container wall. Additionally, the container may be used with different inserts, e.g. depending on the viscosity of the filling material. For example, in place of an insert fixed to the container wall at predetermined level by means of the projections, an insert may alternatively be arranged in the container which is not supported by projections and which can rest for instance on the filling material surface, wherein this insert can be more deeply inserted into the container than the first-mentioned insert provided with the projections. Accordingly, at least two different inserts can be assigned to a defined container, one of these inserts being adapted for fixing to the container wall at predetermined level by means of projections, while another insert can be inserted into the container at different levels, such as the one described above. It will be understood that both inserts can sealingly bear against the container wall over the full circumference.

In the insert provided with the projections, said projections can be arranged above, below or at the same level with a peripheral sealing of the insert. Accordingly, in one embodiment, the projections can sealingly bear against the container inner wall and can be a part of the peripheral sealing. Where appropriate, the insert can also extend below the projections, and a peripheral sealing of the insert extending over the full circumference can be disposed below the projections. Where appropriate, the peripheral sealing of the insert can also be disposed above the projections of the insert, in which the case the sealing preferably also engages into the pockets of the container wall in order to seal also the receiving space of the filling material there below.

The insert which is fixed to the container inner wall at a predetermined level by means of the projections can be arranged spaced from the filling material surface, wherein in particular the bottom of the insert can be spaced from the surface of the filling material, where necessary over the entire surface area thereof.

Further, by said flange, a receiving space separate from the filling material can be provided, e.g. for other components that are to processed along with the filling material, e.g. a hardener composition and/or a preparation device for processing the filling material. The sealing area of the flange with respect to the container inner wall can be arranged in the central part or in the upper part of the vertical extension of the flange. The flange can comprise one or more vertically spaced peripheral sealing portions around the entire circumference with respect to the container inner wall.

The flange can comprise a radial offset, preferably a stepped shoulder, which stabilizes the flange. The following description with regard to the stepped shoulder may also apply to a shoulder or radial offset in general. The stepped shoulder can be radially spaced from the container inner wall such that through this shoulder a certain stiffness of the insert is produced on the one hand and a certain flexibility of the upper rim of the flange is provided on the other hand. There can be arranged at least one sealing area of the flange in the region or at the level of a stepped shoulder of the flange or can be formed by a part of the stepped shoulder which faces the container inner wall. The stepped shoulder can comprise a step sloping downwards and rearwards towards the inner space of the container, i.e. the vertically lower part of the step can be radially inwardly spaced (to a larger extent) than the vertically higher part of the flange. When the insert is more deeply inserted into the container, the upper part of the flange can exert a certain lever action on the lower part of the flange such that the latter is more strongly pressed against the inner wall of the container, whereby the tightness of the insert is increased.

The sealing area can be vertically spaced from the offset or the stepped shoulder within a range of ± ^ 1/3 or ± > 1/4, where necessary ± £ 1/5 or ± < 1/8. The sealing area of the insert can be vertically spaced from the bottom and/or the upper edge of the insert, in each case independently of one another, by an amount equal to or greater than 2 to 3 times or equal to or greater than 5 to 10 times the wall thickness of the bottom of the insert, specifically > 1/8-1/5 or > 1/4-1/3 or > 1/2 respectively of the vertical extension of the flange. The vertical distance can respectively refer to the central part of the bottom of the insert that is penetrated by the main axis of the container.

The upper edge of the insert and/or the insert at the level of the bottom of the insert can be radially spaced from the inner wall of the container independently from one another. The central part of the insert can constitute the or the sole contact region of the insert against the inner wall of the container and the (possibly sole) contact region can be arranged independently of one another within the range of ± ^ 1/3 or ± < 1/4, where necessary within the range of ± ^ 1/5 or ± < 1/8 of the medium height of the flange, where necessary within the range of ± ^ 40-45% of the flange height about the medium height of the flange.

Preferably, the bottom of the insert extends over the entire or almost the entire cross sectional area of the inner space of the container. Where necessary, a small radial space can be left between the insert and the inner wall of the container at the level of the bottom of the insert, this however preferably in such a manner that skinning of the surface of the filling material is avoided or is still within acceptable limits from the aspect of processing, e.g. within a range of < 7 to 10 mm or < 3 to 5 mm or < 1 to 2 mm or <0.3 to 0.6 mm, where necessary also < 0.1 to 0.2 mm.

The flange or the raised rim portion of the insert can comprise several reinforcing ribs spaced from each other in the circumferential direction, which can extend in the vertical direction, at least substantially. Said reinforcing ribs preferably start at a stepped shoulder of the insert or extend beyond the same in the vertical direction. Said reinforcing ribs can be molded to the upper side of the stepped shoulder and/or to the inner side of the part of flange joining the same. Preferably, said reinforcing ribs are molded to the radially inner side of the flange and/or to the upper side of the bottom of the insert. The reinforcing ribs can extend as far as to the bottom of the insert. The reinforcing ribs can be distributed over the circumference of the insert uniformly or preferably non-uniformly, hence the arrangement density of the ribs can be higher in less curved parts of the periphery of the insert, e.g. in the central part of the sides, than in more strongly curved parts, e.g. in the corner parts of the insert. Thus the insert has a sufficiently high flexibility when being inserted into the container, on the one hand, and has a sufficiently high rigidity for bearing against the inner wall of the container in an optimally sealing manner when being arranged at different levels, on the other hand.

Advantageously, the insert is provided with a handle, e.g. in the form of a handle recess, for pulling the insert out of the container. This handle can be arranged on the bottom or in the central part of the insert or on the flange. Preferably, the flange has a handle above the peripheral sealing area against the inner wall of the container, which handle can be designed as a handle recess or indentation such that the insert can be constructed in a manner such as to be closed below the sealing area. By the provision of this handle, the flange can be simply removed from the container without using tools, even if the insert adheres to the filling material as a result of strong cohesion forces. On the other hand, this allows the sealing and bottom area of the insert being optimally adapted to the inner wall of the container and to the filling material. Preferably, said handle is vertically spaced from the bottom of the insert such that the flange is raised from the bottom also at the level of the handle.

Particularly preferred, said handle is arranged on a corner region of the container when the insert is inserted in the container as intended. This corner region of the container can be provided with or arranged adjacent to a tamper-evident closure and/or an opening aid for lifting the lid. Where necessary, said tamper-evident closure and/or said opening aid can be arranged on a corner region of the container adjacent to the handle. Thus the container can be handled particularly easily because when the lid is opened by manipulating the tamper-evident closure and/or the opening aid, the handle recess or the handle of the insert directly faces the user and can thus be easily actuated.

The container and/or the insert can consist of a synthetic material. In its central region and/or in its rim portion and particularly also in the region of a vertically extending flange, the container can present a material thickness of > 0.1 to 0.15 mm or > 0.2 to 0.3 mm, preferably however > 0.4 to 0.5 mm, and even more preferably £ 0.7 to 1 mm. The wall thickness of the insert can amount to < 2.5 to 3 mm or < 1.8 to 2 mm, for instance also < 1 to 1.5 mm. This allows the insert being produced with high dimensional stability which is important for the provision of an optimal sealing area against the inner wall of the container, especially also in a case where the insert is arranged at different vertical levels, while the insert can yet be sufficiently flexible.

Above the bottom, the insert can comprise a receiving space which can be surrounded by the flange on the outside thereof and in which accessories and/or auxiliaries for working or processing the filling material can be stored, e.g. a tool and/or a chemical hardening agent for the filling material. Irrespectively thereof, the insert can be designed in a manner such that it is dimensionally stable when it stores the accessories/auxiliaries or receives a different weight and, when it is freely suspended in the inner space of the container, does not sink more deeply into the container (e.g. in a container without filling material, or vertically spaced from the filling material, with the insert not being in its lowermost inserting position). This can be the case in a freely suspended state under a weight load of < 10-20 g or > 50-100 g or > 250-500g, e.g. ^ 500-1000 g or < 150-250 g or < 50-100 g or also ^ 10-20 g.

The insert can be designed in a manner such that the insert or the weight imposed to it does not sink into the filling material when the insert rests on the surface of the filling material. To the end, the insert can present a sufficiently high inherent rigidity and/or the rim of the insert can be constructed in a suitable manner, for instance sufficiently raised, and/or can sufficiently tightly bear against the inner wall of the container. This can be the case under a weight load of > 100-200 g or > 500-1000 g or preferably ^ 1500-2000 g or > 2500-3000 g, and the weight load can for example be ^ 15-25 kg or < 8-10 kg or < 4-6 kg, optionally < 2-3 kg.

Further, the container according to the invention can present a peripheral continuous skirt that is molded to the region of the upper rim of the container. The skirt can present a substantially horizontally extending region and/or a substantially vertically extending region. The skirt can be molded to the container in the upper rim region thereof or can be molded to the upper rim of the container. It is particularly preferable for the skirt to have a channel for receiving the lid rim of a lid that is fixed as intended, preferably over the entire circumference, optionally with the exception of a part that is provided with a tamper-evident closure, or also over a part of the circumference, optionally with regions distributed over the circumference of the container. Thus the rim of the lid can be fixed to the lateral walls of the channel radially inwardly and/or radially outwardly, or at least a deformation of the rim of the lid can be bounded by the skirt. The rim of the lid can bear against the lateral walls of the channel on the radially inner side and/or on the radially outer side. The skirt can comprise a peripheral portion joining the channel substantially horizontally and radially inwards and/or radially outwards from the channel and can be respectively molded to the upper rim portion of the channel. The rim of the lid can be placed on the bottom of the channel or can be slightly spaced therefrom. Thus the skirt can have a comparatively large radial extension and can thus stabilize the container especially during a stirring action for homogenizing the filling material. In particular, due to the construction of the skirt according to the invention, the container can be fixed or held manually or by machine during the stirring action. Additionally, the containers can be stacked, even at a high weight of the containers, while good sealing is maintained between the container and the lid.

Preferably, the lid comprises a handle of removing the lid manually, which handle horizontally protrudes from the lid, at least substantially, and particularly preferably, the container can comprise a skirt provided with a channel that is engaged by the rim of the lid. Thus the lid can be easily manually removed, even if the skirt has a larger width. The handle can be provided above the skirt and optionally can be supported on the upper side of the skirt or can be slightly vertically spaced therefrom, e.g. by ^ 3-5 or < 1-2 material thicknesses of the handle. Radially outwardly of the handle a tamper-evident closure of the container can be disposed which covers the handle towards the outside and preferably vertically extends beyond the handle.

Preferably, the at least partially peripherally extending skirt of the container which is molded to the region of the upper rim of the container or to the upper rim of the container is provided with a mounting for a carrying handle and/or with a hand engaging portion that allows the skirt being engaged manually. In this manner, the container can be held, e.g. during the stirring action for homogenizing the filling material, or can be carried. Accordingly, the manual engaging portion is incorporated in the peripheral flange of the container. By manually gripping the manual engaging portion, the container can be manually lifted, which makes processing of the filling material easier. Particularly preferably, the mounting for the carrying handle is arranged on the manual engaging portion, for example in the central part thereof. The manual engaging portion is constructed in a manner such that a phalanx of a person using the container can fully engage into the manually engaging portion. To this end, said manual engaging portion can present a width in the radial direction of > 8 to 10 mm or > 15 to 20 mm. Preferably, the manual engaging portion is reinforced in a manner such that also the region around the mounting for the carrying handle is reinforced.

The invention also comprises a container as the one described within the scope of the present invention, which is at least partially filled or filled up to a technically permissible maximum filling level with a filling material that may contain volatile components. Preferably, the insert is placed on the surface of the filling material or is only slightly spaced from the surface of the filling material. A slight spacing may exist if the insert is spaced from the surface of the filling material by < 7.5-10% or < 3-5% or < 1-2%, preferably < 0.5-0.75% or < 0.15-0.3% of the height of the container. The vertical spacing of the insert from the surface of the filling material can for example amount to <10-15 cm or < 5-7 cm, preferably < 2 to 3 cm or < 0.5 to 1 cm, particularly also < 0.15-0.3 mm. In this manner the container volume above the filling material and exchanging gases with the filling material is minimized such that undesired alterations of the filling material as result of out-gassing volatile components are minimized.

In particular, the filling material can be emulsion bitumen or an emulsion or dispersion of a different sealing agent, particularly for the construction sector, or for instance a plastic resin. The filling material can be pasty or viscous, and can preferably be still free-flowing at 20°C under the influence of gravity, although not being limited thereto, and can also be a powder. The filling material can be a Newtonian fluid or particularly a non-Newtonian fluid or composition. The filling material is not limited thereto, it can also be construction plaster (e.g. wall plaster) such as for example colored plaster, plastic resin (e.g. epoxy resin) or a different building material or coating material such as for example screed (especially liquid screed), but also a food product. In said insert there can be generally present a second component that can be used together with filling material (mostly the main component), e.g. also a tinting agent, another food product component or the like, which can be mixed with the filling material shortly before its use or which can be used in combination with the filling material (2-component system).

The filling material can also present a dynamic viscosity of £ 200-500 mPas or also^ 1000-2000 mPas or > 5000 mPas, in particular also £ 10000-25000 mPas or > 50000 mPas, especially > 1x105-5x105 mPas, where appropriate also > 106-107 mPas. All in all, the filling material can still be free-flowing, particularly at a temperature of 20° or 40° or 60° Celsius. The viscosity of the filling material can be < 109-1010 mPas or where appropriate also up to 1012-1014 mPas or higher, particularly < 106-108 mPas or < 104-103 mPas.

Particularly preferably, the container is designed at least substantially as a rectangular container, including square containers, with preferably a corner radius of £ 50 mm and/or < 600 mm. In particular, the corner radius can amount to £ 60-70 mm, preferably > 80 mm. The corner radius can preferably amount to < 150-20015 mm, particularly preferably to < 125 to 150 mm, where appropriate also < 300-400 mm. Optionally, the corner radius can also amount to < 600-800 mm. In this manner a container is provided in which a highly viscous material such as bitumen for example (e.g. emulsion bitumen) can be particularly effectively homogenized by means of a stirring tool. It turned out that due to the very high viscosity and possibly also due to thixotropic properties of the filling material, particularly good homogenization is achieved with the stated corner radii, e.g. when the hardening agent is stirred in. This is attributed to the fact that with the above-mentioned corner radii, a suitable material flow is possible also in the region of the corner radii even in case of a very viscous material, so that the partial volumes present in these areas are sufficiently homogenized, although there are limits to an increase in the stirring speed due to the high viscosity of the filling material. On the other hand, such a container has a shape which is clearly different from a round shape so that the available space for storing the container, e.g. on a pallet, is utilized very efficiently.

The lateral walls of the container, particularly with the above-mentioned corner radii, can be outwardly curved, and particularly the central part of the lateral walls can have the form of a section of an arc of a circle. The arcs of the lateral walls, particularly in the central part of the lateral walls, can each continuously pass into the arcs of the corner regions. The central parts of the lateral walls are passed-through by the main planes of the container, which main planes can represent mirror planes of the container body. Preferably, the corner regions and the lateral walls can each be described by a circular arc which respectively continuously pass into each other. The radius of curvature of the adjacent lateral walls can be the same or different. Accordingly, the entire circumference of the container can be defined by only 2 or 3 different radii of curvature, as the case may be.

The ratio of the radii of curvature of the central parts of the lateral walls to the corner radii preferably is > 2-3, preferably > 5-7 or particularly preferably >10-12 or > 15-20 or also > 30-50 or > 50-100. The ratio can be < 200-500, < 75-100 or ^ 30-30, in case also < 20-25 or < 10-15, the corner radius being smaller than the side radius of the container.

The ratio of length and width of the container can be < 1:1.75 or < 1:1.5, in case also ^ 1:1.35 or< 1:1.25, in case < 1:1.15 or < 1:1.1. The container can substantially be a square container. Surprisingly, it turned out that smaller ratios, e.g. < 1:1.35 or < 1:1.15, result in a more uniform material flow during stirring which also covers the corner regions much better and thus reduces the time needed for homogenization.

The container can have a container volume of ^ 10 to 15 I or for instance also > 20 to 25 I, in case the container volume can also be > 0.5-1 I or > 2-5 I, without being limited thereto. The container volume can be < 50 to 75 I. A method for filling a container can proceed in a manner such that after filling the container with filling material, preferably up to the predefined filling level, an insert according to the invention is introduced into the container and is caused to set down on the surface of the filling material so that the insert comes in contact with the surface of the filling material. Thereafter, the container can be originally closed with a lid. Preferably, the insert is placed onto the surface of the filling material in a manner such that the bottom of the insert is in planar contact with the surface of the filling material, in particular over the entire surface, in each case with respect to the area of the bottom of the insert. Where necessary, at the edge of the bottom of the insert a gap can be left between the bottom of the insert and the inner wall of the container, e.g. in the form of a peripheral, downwardly open channel between the insert and the container wall. Preferably, the insert is designed in a manner such that when the filling material shrinks or settles, the insert together with the settling filling material is drawn under cohesion to the surface of the filling material (more deeply) into the container - eventually under the load of an additional weight placed onto insert or without an additional weight - preferably with the insert being continuously sealed towards the upper space of the container. Preferably, the process according to the invention is carried out in a manner such that after being inserted into the container filled with the filling material, the insert is weight-loaded, specifically in such a way that the bottom of the insert comes into contact with the surface of the filling material, preferably in a planar manner or over the full surface with respect to the bottom of the insert. Preferably, the insert is weight-loaded before the bottom of the insert is brought into contact with the surface of the filling material, for example by the insert and the weight (e.g. added) are placed in the container immediately after each other. The weight can be dimensioned in such a way that the insert under the weight sinks in deeper into the container, until it contacts the surface of the filling material, with the result that the time required for filling is particularly short. That the insert sinks in deeper can refer to that the insert after being loaded with the weight sinks in deeper into the container over time and/or that the insert sinks in deeper into the container with weight load than without weight load. Optionally, the insert can also be weight-loaded only after it is placed onto the surface of the filing material. The added weight (e.g. auxiliaries and/or accessories) can remain in the container after the container is closed, when the container is originally closed. The package can also be originally closed before the insert (preferably loaded by weight) has lowered to the surface of the filling material, this preferably with view to a subsequent filling check. The lowering to a lower level can be enhanced if necessary by exerting a vertical pressure by means of an external pressure element. Preferably, such a supporting action is not performed or is not absolutely necessary. The weight can also be placed onto the insert after the insert has been contacted with the surface of the filling material. The insert and the weight should be dimensioned in such a manner that when the filing material shrinks or settles, the bottom of the insert remains in contact with the surface of the filling material and the container withdraws more deeply into the container. The weight can be an accessory and/or auxiliary, in particular a chemical composition such a chemical hardening agent for processing the filling material. The weight can be dimensioned as described above. If the insert is loaded by a weight, the container can be originally closed with a lid before the insert is contacted with the surface of the filling material. Generally within the scope of the present invention, the sealing area or the sealing lip can be designed so as to be flexible or elastically deformable in a manner such that when the insert is lowered to the surfaces of the filling material, air trapped in the lower space of the container can escape to the upper space of the container under a deformation of the sealing area.

The arrangement of a separate film or of a different intermediate layer between the surface of the filling material and the insert can be generally omitted as a result of using the insert according to the invention. The container can be formed without an inwardly protruding bead that can comprise continuous peripheral sections or several sections separated from each other in the circumferential direction and on which the insert inside the container is placed. Accordingly, the container wall is preferably smooth and free of protrusions, at least over the height over which the insert can be displaced vertically.

In the following, one embodiment of the invention will be described by way of example and with references to the attached drawings, wherein it is shown by

Figure 1 a cross sectional view of a container with an insert at a first level (Figure 1a) and at a second level (Figure 1b);

Fig. 11,12a container according to the invention with an insert in a modified form (Figure 11), and the inner wall of the container in a detailed view (Figure 12).

The embodiment shows a container 1 with a lid 2 and with a container inner space 3, said container presenting a vertical height h. The container is adapted for receiving filling materials 1b comprising volatile components such as emulsion bitumen for example, or contains those materials. To prevent volatilization of the volatile components and thus possible skinning or the formation of a film on the surface of the filling material, the invention provides an insert 10 that can be lowered in the container inner space 3 to different levels hi, h2 (hi Φ h2) and can hence be positioned with different distances from the bottom of the container, wherein the bottom of the insert can rest on the surface of the filling material such that the container inner space is separated into an upper part and a lower part 3a, 3b, wherein the filling material can be present in the lower part. The level refers to a uniform reference point of the insert, e.g. the bottom of the insert or the upper edge of the insert. Thus a compensation is possible even if the filling material shrinks, for example by settling after the filling, such that the insert can be reliably placed onto the surface of the filling material or can be positioned so as to contact the filling material surface after settling or after any other change of the filling level (preferably without removing filling material), by vertically displacing the insert, so that a film formation of the filling material, e.g. due to the escape of volatile components, is effectively prevented. The insert is preferably designed in a manner such that this is possible also in a container which conically tapers towards its bottom, e.g. by an angle of approx 2 degrees with respect to the container main axis 1a, and such that the container can be stacked into containers of the same construction. The container may apply in a sealing manner against the inner wall 5 of the container over the entire circumference.

In its central part, the container can have a bottom 11 that can be substantially planar and continuous on the lower side thereof. This allows the insert to be easily placed with its full area onto the surface of the filling material. Smaller projections of the insert, for instance in the form of grooves that may serve as a reinforcement of the bottom area, can be provided if necessary. Preferably, the bottom of the insert is free of downwardly directed protrusions such as reinforcing ribs or the like, and is smooth on the lower side. The lower side of the insert can be smooth. The insert 10 can comprise a flange 12, which preferably extends fully or at least partially above the bottom 11. The insert generally comprises a peripheral contact area 13 against the container inner wall 5, which can be preferably designed as peripheral sealing area 13a against the container inner wall 5, e.g. in the form of a sealing lip (cf. Figure 2). This contact and/or sealing area can be arranged at the level of the bottom of the insert and/or at the upper region of the flange, e.g. on the upper edge 14 of the flange, and/or in the central part 15 of the flange and/or generally on a stepped shoulder of the flange which in this case is arranged approximately at a level of half the height of the flange. The insert can generally comprise two vertically spaced contact and/or sealing areas against the container inner wall. These can be contacted with the container inner wall over the entire circumference thereof at least at certain levels of arrangement of the insert, or when there are different depths of insertion of the insert in the container inner space, different contact / sealing areas may be contacted with the container inner wall.

The insert is constructed for a vertical displacement at least over a part of the height Δ h of the container inner wall (cf. Figure 1), namely preferably in a manner such that the insert arranged at different vertical levels hi, h2 always contacts the container inner wall, preferably over the entire circumference, and especially so as to be sealing against the entire circumference of the container inner wall. Accordingly, the insert can be vertically spaced from the upper edge 6 of the container, particularly from the fixing and/or contact region thereof. The insert can be configured in a manner such that by being inserted into the container under its own weight, the insert is fixed against the inner wall 5 of the container, preferably exclusively against the container inner wall, wherein the sealing area can serve as a fixing area. The insert is designed so as to be vertically displaceable with respect to the container wall, for example within a range of 0.5-5 cm, while the insert preferably remains constantly applied against the container inner wall and/or constantly seals against the container inner wall.

The peripheral outer rim 16 of the insert, which is presently formed by an exemplary sealing area 13a, is adapted to the cross sectional shape of the container inner wall and hence is congruent with the container inner wall. The contact and/or sealing area of the insert, e.g. a sealing lip or a part of the flange, can radially outwardly protrude with respect to the adjacent parts. For example, to this end, the sealing area can be molded to the flange on the outer side thereof. The sealing area can be deformable during insertion into the container, e.g. it can be designed in a manner such as to contract or to be compressed in the fashion of an umbrella (i.e. it can be narrowing while forming a cone). A foamed material can for example be used for this purpose. Preferably, the sealing area on the one hand and the bottom and/or flange of the insert on the other hand, are made of a similar material. Thus the outer rim of the insert can be adapted to the container inner wall while providing for constant sealing, even if the insert is arranged at different levels in the container, and the bottom of the insert can be comparatively stable. Here the sealing area 13a of the insert is preferably spaced form the upper edge 12 of the flange. The outer rim 11a of the bottom of the insert is slightly spaced radially from the container inner wall by the gap 11b, wherein the insert can be fixed against the container inner wall under its own weight.

The rim area of the insert can comprise a stepped shoulder 19 or a generally radial offset (Figure 2), with a flange portion 19a, 19b extending axially above and axially below the same, which flange portions can respectively include (independently of one another) a smaller angle with respect to the container main axis 1a than the container wall, e.g. extend parallel to the axis. Even when the insert is introduced into the container, it is only the sealing area that will bear against the container inner wall. The stepped shoulder is here arranged on the flange 12, for example in the central part 15 thereof.

The insert 10 inserted into the container forms on the rim portion thereof a channel 17 open downwards and towards the receiving space of the filling material, said channel being arranged between the flange 12 and the container inner wall 5. Preferably, the channel is closed towards the upper space 3a of the container. If the insert is urged against the preferably pasty or liquid and especially viscous filling material, the bottom of the insert can be placed onto the surface of the filling material over the entire area thereof, even if a certain volume of air is trapped in the space between the filling material and the insert. The filling material can partly penetrate into the channel 17, particularly if the insert is loaded by a weight, e.g. a component to be processed together with the filling material such as a chemical hardening agent or a tool. The vertical extension of the channel 17 is preferably so dimensioned that the filling material under the load applied to the insert by an additional weight, is arranged below the bottom or the upper edge of the channel or is applied against the channel without pressure. Towards its upper side, the channel 17 can be closed by the sealing area 13a or by the sealing lip. This can generally apply within the scope of the present invention.

The stiffness of the insert and the expansion of the bottom area (corresponding to the bearing surface of the bottom of the insert on top of the filling material) are preferably so dimensioned that even when a weight of £ 100-200 g or > 500-1000 g, preferably > 2-3 kg, preferably <12-15 kg or < 7-10 kg acts upon the insert, the insert will not penetrate into the filling material to such an extent that the filling material penetrates laterally past the insert and into the upper space 3a.

The outer rim, in particular the flange 12 and especially the stepped shoulder 19, can be stabilized by several circumferentially distributed reinforcing ribs 18 (Figure 2). This increases the inherent rigidity of the insert on one hand, possibly also in the region of the contact/sealing area 13a. The insert is designed in a manner such that it can be stacked so that the stacked inserts are partially nested. Here the reinforcing ribs are non-uniformly distributed over the circumference of the insert, whereas no reinforcing ribs 18 are arranged on the corner regions of the insert or are arranged in a smaller number than in the central lateral regions.

For easy removal of the insert from the container, the insert and preferably the flange 10 thereof is provided with a handle 30, for example in the form of a handle recess or also in the form of a gripping tab. This turned out to be particularly useful because the insert placed on the filling material can often be not pulled out due to cohesion forces. The handle 30 can be arranged above the sealing area of the insert, or the region of the handle recess for its part is sealed against the inner wall of the container, for example by a sealing area radially protruding towards the inner wall of the container. The handle or the handle recess is separated in height from the bottom of the insert by a part of the flange.

The insert can be positioned on the container in a manner such that the handle 30 is disposed on a corner region 31 of the container, which is equipped with the tamper-evident closure 32 and/or with an opening aid for lifting the lid at least partially, or is disposed on an corner region 31 of the container adjacent said tamper-evident closure and/or said opening aid (cf. Figure 3). This enables easy handling of the container, because after the lid is lifted, the handle directly faces the user for being gripped by the user.

Preferably, the container is generally non-round and/or non-elliptical and is designed in the present case as a square container, wherein the lateral walls 32 can outwardly bulge in the central part 33 thereof. The corner regions 31 of the container respectively have a corner radius that can constantly pass into the lateral wall. In the present case, the corner radius has a diameter of 100 to 200 mm. The radius of the central part 33 of the lateral wall is approximately 12 times the corner radius. This allows also highly viscous filling materials to be homogenized in the container material by means of a stirring system. Generally within the scope of the present invention, the corner or later wall radius (central part) can be determined by the upper edge of the container or by the original contour of the container at the bottom of the container (on the inner wall of the container). In the Figures, the transitions between the corner and the lateral wall regions are each symbolized by vertical lines.

The container further comprises a peripheral skirt 40 that is molded to the container in the region of its upper edge (Figures 2, 5). The skirt 40 has a channel 41 that is engaged by the rim 2a of the lid and is thus secured in position radially inwards and radially outwards. Further, the skirt 40 has a mounting 43 for a carrying handle, e.g. in the form of opposing engagement openings for the ends of the carrying handle. Alternatively or additionally, the skirt has a hand opening portion 45 for engaging the skirt manually, said hand opening portion being fully integrated into the skirt. This facilitates carrying the container (especially with both hands in order to avoid the free-flowing filling material from being undesirably moved) and/or optionally holding the container manually during the stirring action. The mounting for the carrying handle is here provided on the hand opening portion 45. If necessary, the hand opening portion can also be formed on a different circumferential region of the skirt. The hand opening portion is designed in a stabilized manner and hence also the mounting for the carrying handle. The lower part 46 of the skirt and engagement portion is arc-shaped towards the radial outer side in order to form a flat manual engagement portion. The hand opening portion is molded to the outer wall of the container by means of webs on both sides.

The lid 2 of the container comprises a handle 50 for manually lifting the lid (Figure 7), which handle can horizontally protrude from the lid at least partially. The handle 50 or tab can be supported on the upper side 40a of the skirt 40. Forward of the handle a tamper-evident closure 32 can be provided, e.g. in the form of a tear-off strip, and an engagement recess can be provided below the lid handle. Thus the lid can be easily lifted even if the skirt has a large width.

To the lower side of the skirt 40 a plurality of reinforcing ribs 42 can be molded which can extend on both sides of the channel. These reinforcing ribs 42 can present a smaller elevation in the hand opening portion than in the remaining circumferential region of the container (ribs 42). These ribs 42 can protrude downwards from the skirt so that the lower edge 42a of the webs will contact the upper edge of the container or the upper region of the container and prevents the stacked container from sinking in further (Figure 6) when the containers are stacked into one another. This facilitates gripping the hand opening portion in a container stack.

The lid 2 has a central part or bottom 2b, wherein the insert is arranged below the bottom of the lid, but where necessary, an upwardly protruding rim portion of the insert can be arranged between the inner flange 2c of the lid (Figure 2) and the inner wall of the container and/or the insert can be applied against the lid in a manner spaced from the container wall, e.g. against the lower side thereof. The insert or at least the fixing area thereof on the container can be arranged completely under the fixing area of the lid on the container.

If the container is filled with the filling material 1 b at least partially or fully from the technical aspect of filling, the insert 10 can rest on the surface of the filling material or can be spaced therefrom only slightly. The filling material can present a dynamic viscosity of approx 105-106 mPas. In particular, the filling material is emulsion bitumen. After the filling of the filling material, the insert can be inserted into the container, e.g. until it contacts the surface of the filling material. After the insert is inserted into the container, an accessory or auxiliary such as a chemical hardening agent can be positioned in the insert, namely as soon as the insert meets the surface of the filling material (or optionally also when the insert is still spaced from the surface of the filling material). By loading the insert with the additional weight, the insert is lowered and contacted with the surface of the filling material. The bottom of the insert can preferably rest on the filling material over the full area thereof. When the filling material shrinks, the insert which has a sufficient dimensional stability (preferably while maintaining its shape, except of possible deformations in the sealing area) is kept covering the surface of the filling material.

The Figures 8 to 10 show a further embodiment of a container having an insert according to the invention. The differences over the container having an insert according to the exemplary embodiment according to the Figures 1 to 7 will be described in the following. Incidentally, reference is made to the full contents of the further embodiments of the subject of the invention, including the embodiment according to the Figures 1 to 7, which can correspondingly apply also in the present case.

The container 80 according to this embodiment comprises at least two or three, preferably four, pocket-like indentations 81 that can be formed as bulging portions of the container wall 82. Optionally, the pockets 81 can also be formed as regions having a smaller wall thickness. The insert 84 is provided with radially outwardly protruding projections 85 that can engage into said indentations 81 so that the container can be fixed at a predetermined level in the interior of the container. The projections 85 of the insert then rest on the bottom regions 86 of the indentations. Said indentations 81 extend towards the upper edge 80a of the container that far, and possibly as far as to the upper edge of the container, so that the insert can be introduced into the container merely by vertically lowering until the insert 84 is fixed at a predetermined level against the container wall in a form-fit manner, e.g. until the projections 85 meet the bottom regions 86 of the indentations. The pockets or indentations 81 are here arranged in the corner regions 87 or in the regions with the largest curvature of the container wall. The projections 85 engage into the indentations in a manner such that the same fix the insert against twisting in the interior of the container. The projections of the insert (and/or of the container wall) are stable to such an extent that the insert can also receive a weight, for example a pack with a hardener component for the filling material such as a bitumen composition for example. The indentations 81 can taper towards the bottom of the container so that the horizontally aligned insert can be introduced in a self-centering manner through the container opening and lowered vertically into the container. Optionally, the insert can be fixed to the container inner wall 82a by a certain locking, though this is often not required. The indentations 81 have a vertical depth, and the projections are positioned on the insert in a manner such the bottom 88 of the insert is (preferably only slightly) spaced from the surface of the filling material or can almost rest on the surface of the filling material. All in all, the insert can be fixed to the container inner wall 82a in a manner secure against tilting, even under unfavorable transport conditions and under the load of a weight.

As shown in Figure 10, the projections 85 can be arranged at the level of the peripheral sealing lip 89 of the insert so that the lower sides of the projections are sealingly applied against the container inner wall 82a, thus sealing the container inner space arranged below the insert against the container inner space arranged above the insert. Optionally, the projections can also be arranged above a peripheral sealing or sealing lip 89 of the insert, wherein the term "peripheral" as used herein is always understood to mean "fully peripheral".

By the provision of the projections 85, any tilting of the insert with respect to the container is securely prevented, even if a weight is arranged on the insert and even if the container is not transported in a horizontal orientation, for example when the container is carried by hand.

The container 80 can be associated with an additional insert 10 according to the exemplary embodiment shown in the Figures 1-7, which additional insert can be disposed in the container alternatively to the insert 80. The insert 10 can then be introduced into the container 80 that far that the sealing area 13a of the insert 10 sealing contacts the container inner wall 82a below the pocket-like indentations, e.g. at the level of the contact region 82bof the container inner wall in the sealed seat.

The Figures 11,12 show an inventive container having an insert, which is a modification of the container according to the Figures 8-10, however an advantageous implementation is generally possible within the scope of the present invention, hence also in the embodiment according to the Figures 1-7. In this case, securing means 81a are provided on the inner wall of the container and optionally additionally or alternatively on the inner side of the lid, wherein these securing means cooperate with a fixing area 85 of the insert while securing the position of the fixing area radially inwardly.

Securing the fixing area of the insert radially inwardly prevents that the fixing area disengages from the corresponding fixing area of the container inner wall and that the insert becomes instable and tilts or becomes deformed and can get into the filling material as a result of an objet or article having a high weight such as a hardener component, a processing tool etc. being placed into the insert. In particular, the securing means can engage the projection and preferably two or more projections 85 and even more preferably all of the projections 85 of the insert in a securing manner by engaging into the pocket-like indentations of the container inner wall. In particular, the securing means can engage the fixing area of the insert in a form-fit manner in order to secure the position of the insert radially inwardly. The securing means can be respectively provided as a projection, particularly as an axial upwardly protruding projection that engages a recess of the insert in securing manner. In a reversed manner, the securing means provide a recess, which is engaged in a securing manner by a projection such a securing pin of the insert for example. In particular, the securing means can be arranged on the bottom area of the pocket-like indentations. The provision of the securing means turned out to be especially beneficial during the transportation of the container when the container is loaded with a (high) weight, and/or at elevated ambient temperatures when the container experiences a certain thermal expansion, in order to secure the insert in a horizontal orientation in the container. On the pocket-like indentation or as an extension thereof, stacking fins 86 can be arranged on the outside of the container, which facilitate stacking of the containers into one another on the one hand and stabilize the pocket-like indentations and securing means 81a on the other hand.
