Abstract

The invention relates to a container with a plastic cover, used as a paint container, especially for solvent free paints. Said container has a cross section which is preferably round or oval and has a wall extending from the bottom to the opening of said container. Said wall forms for said container a substantially conical widening which is oriented towards the opening of said container, and it has an upper peripheral sealing edge for sealingly supporting the cover. Said container is characterised by an outwardly protruding collar (9) and formed in a single piece under the sealing edge at a distance therefrom. Said collar forms an open channel oriented towards the opening of the container. When the cover (2) is placed on the container, said channel is closed by a peripheral cover skirt and forms together with said skirt a closed outer contour of said container (1).

Description

 Paint can

The invention relates to a container with a lid made of plastic as a paint can, in particular for receiving solvent-free paints with a preferably round or oval container cross-section, with a wall extending from a container bottom to a container opening, which is an approximately conical extension of the container in the direction of the container - Opening forms and which has an upper circumferential sealing edge for the load-bearing and sealing reception of the lid.

Such a container is known, for example, as an injection-molded single-rim plastic bucket from utility model G 94 03 122.3. The container described there can be stacked excellently due to the conicity of its wall. In addition, the edge design of the bucket or the profile of its wall in the edge area is selected such that damage to adjacent buckets during stacking or transport, for example in pallets, is reliably prevented. However, the advantageous design and construction features of such a bucket cannot simply be transferred to a paint can, to which other usage requirements have to be met.

For example, such paint cans should be made of transparent material and have an optically appealing outer shape. The relatively complex design of the edge of the plastic bucket known from utility model G 94 03 122.3 cannot easily be transferred to a light and small paint can if it is to be produced inexpensively using the plastic injection molding process.

Basically, as already mentioned at the beginning, there are also other ergonomic requirements for a small can that can be gripped with one hand than for example a 25 1-color bucket. Transparent cylindrical cans are available as cans for solvent-free varnishes, which have a relatively simple and open edge profile, the upper edge of these cans being designed as a sealing edge onto which a plastic cover can be snapped in a sealing manner. In the intact and unopened state of the can, the lid is connected to a retaining ring via a tear-off sealing tape, which in turn engages behind a circumferential rib on the outer wall of the can.

These containers or cans have the disadvantage that they cannot be stacked one inside the other when not filled. In addition, the lids of the known cans are not designed to be stackable and suitable for automatic machines. H. these are not designed so that they are centered on top of each other. Such lids have to be opened by hand after filling the cans. In addition, the construction of the tamper-evident closure in the form of a sealing tape or a tear-off band is relatively complicated, so that the production of a corresponding injection molding tool is complex and expensive. Finally, the lid construction has the disadvantage that, after the sealing tape has been torn off, sharp edges are formed, which can lead to injuries in the event of unfortunate handling.

The can body itself is also not very stable, especially when subjected to transverse loads or when the can walls are pressed in, especially when the lid is not in place.

The use of transparent cans for filling varnishes has the very special advantage that only a single container with different labeling can be used for a wide variety of varnishes.

The object of the invention is therefore to develop a container of the type mentioned at the outset in such a way that it is stackable, stable and visually appealing and of simple construction. The object is achieved according to the invention in that the container below the sealing edge and at a distance therefrom has an integrally formed collar which projects outwards and forms a channel which is open in the direction of the container opening and which is closed by an attached cover apron by the attached cover is and forms a closed outer contour of the container with this.

A container designed in this way combines various advantages, for example, the second edge region of the container formed by the collar ensures that dripping paint is collected from the upper edge of the can, the can can be better gripped with one hand and, last but not least, the collar gives the container sufficient stability. The stiffness of the container wall against indentation increases considerably.

It is particularly noteworthy that the apron with the collar forms a closed contour without sharp-edged transitions. The edge profile of the bucket according to the invention is also open.

In the preferred embodiment of the bucket according to the invention it is provided that the collar and the cover apron each have arc-shaped cross sections and form a rounded, bead-like outer contour when the cover is attached. On the one hand, this bead-like contour can be easily gripped under with one hand; H. it ensures that the container does not slip out of hand, on the other hand it is ensured that the lid placed on the container is not easily grasped and opened.

The edge of the lid apron preferably closes flush with an outer edge of the collar in the attached state. This advantageously prevents the lid from being pried open by the lid apron being caught or caught on an adjacent container, a shelf edge or the like. The diameter of the lid in the area of the lid apron can, for example, be slightly smaller than the outer diameter of the collar, so that, taking advantage of the effect that the lid apron expands when the lid is opened, the edge of the lid apron in the attached state is flush with the outer edge of the collar .

Advantageously, a plurality of spaced-apart, integrally arranged reinforcing webs are provided in the groove formed by the collar, which serve to stiffen the groove or reinforce the container. The reinforcing webs also prevent the collar from being pressed in, which would result in the edge of the apron being accessible.

In a preferred embodiment of the container according to the invention it is provided that vertically extending ribs are provided on the wall of the container, the dimensions and arrangement of which are selected such that they only allow containers stacked one into the other to be pushed into each other than the sealing edge of a container does not abut the collar of the container pushed into it. Above all, this improves the ability to unstack the unfilled containers.

The bottom of the container is expediently provided with a circumferential bottom support rib which, when the containers are stacked one on top of the other, interacts with an annular groove in the lid of another container.

It is advantageous if the bottom of the container is convex. The bombing of the bottom of the container improves, among other things, the residual emptiness of the container.

The container was preferably made of transparent plastic by injection molding.

So that at the level of the filled container forming lugs or condensate depositing on the inside of the container are not visible, the collar expediently has a structured surface, as a result of which a visually clean finish of the filling level is achieved by reducing the transparency in this area. The lid can have at least one groove or bead on its upper side, ie on the upper side when the lid is open, for receiving the bottom-standing rib of another container.

According to a preferred embodiment of the container according to the invention it is provided that the lid is also cambered. A brush can be inserted into this bombage of the cover, for example with the cover open, on the inside thereof.

It is useful if the radius of the bombing of the lid corresponds approximately to the radius of the bombing of the container bottom, so that stacked filled containers center on one another.

A tamper-evident closure is preferably provided in the lid apron.

As a tamper-evident closure, for example, a tab that can be at least partially removed from the apron by means of a perforation can be provided.

It is particularly advantageous if this tab is not completely detachable, but is, for example, captively connected to the cover apron on one side via a film hinge, which in principle contributes to avoiding garbage.

The lid can be gripped under in the area of the tab that has been removed. To prevent fingers from jamming when the lid is tight, the lid apron can be reinforced in the area of the predetermined breaking line of the flap of the tamper-evident closure. The lid apron expediently has twice the wall thickness in this area. The invention is explained below with reference to an embodiment shown in the drawings.

The container 1 shown in Fig. 1 is designed as an injection molded, transparent plastic can for receiving solvent-free paints. The lid 2 placed on the container 1 is also injection molded from plastic, which is not transparent in the illustrated embodiment.

The container 1 has a round cross-section and its wall 3 forms a conical widening of the container 1 from the container bottom 4 in the direction of the container opening 5, so that the stackability of several unfilled containers 1 is ensured. The wall 3 of the container 1 forms an upper sealing edge 6, which has a circumferential snap edge 7, which is engaged behind by a circumferential locking projection 8 of the cover 2 when the cover 2 is attached.

The wall 3 of the container 1 is provided on its outside with a circumferential collar 9 which forms a channel which is open in the direction of the container opening 5. In this groove formed by the collar 9, reinforcing webs 10 extend between the collar 9 and the wall 3 of the container 1, each of which are aligned radially and are arranged distributed over the entire circumference of the container 1. The collar 9, which is also transparent, is provided on its outside with a structure 11 which reduces the view through the container 1 in the region of the collar 9.

The container base 4 is cambered and provided on its underside with a circumferential base support rib 12.

As can be seen from FIGS. 5 and 6, vertically extending ribs 13 are provided on the wall 3 inside the container 1, approximately in the lower third of the container 1. FIG. 5 clearly shows that the ribs 13 only allow containers to be pushed into one another to the extent that the sealing edge 6 of the lower container 1 does not abut the collar 9 of the container 1 pushed into it.

Both the cover apron 14 and the collar 9, as can be seen particularly well from FIG. 6, each have an arcuate cross section, which forms a rounded, bead-like closed outer contour when the cover 2 is attached. The lower edge 15 of the apron 14 sits flush on the edge 16 of the collar 9.

The largest outer diameter of the cover 2 is slightly smaller in the unloaded state than the largest outer diameter of the collar 9; if the cover 2 is put on, the presses Sealing edge 6 of the lid apron 14 slightly outwards, so that the edges 15, 6 of the lid apron 14 and the collar 9 lie flush on one another and the outer contour of the container 1 has no projections and edges.

A tamper-evident tab 17 arranged in the cover apron 14 is provided as tamper-evident closure. The tab 17 has two separable connections 18 to the cover apron 14 and its handle end 19 protrudes slightly from the outer contour of the cover 2. At the end remote from the handle end 19, the tab 17 is captively connected to the cover apron 14 via a film hinge 20. As can be seen in particular from FIG. 4, the cover apron 14 is designed in the area of the tamper-evident closure with approximately twice the wall thickness, so that the cover 2 can be comfortably gripped under in this area when the tab 17 has been torn open. In the resultant recess 21 in the cover apron 14, the handle part 22 of a brush can be inserted, for example, with the cover 2 turned over. The lid 2 also has a convex area 23, the radius of which corresponds approximately to the bombing of the container base 4.

A circumferential bead 24 is provided on the inside of the cover 2, which forms a corresponding elevation on the outside or top of the cover 2, which in turn delimits the cambered region 23 of the cover 2. This contour allows centering of stacked filled containers on one another, as can be seen from FIG. 7.

The bead 24 simultaneously prevents the paint from running into the closure area of the lid when the lid 2 is removed and turned over.

8 illustrates the stackability of the lids 2 in accordance with the machine. Paint can
