Description

Container for a coating composition applicable with roller, and kit that includes the container.

Technical Field of the Invention

The invention is included in the field of containers and tools for paints and other compositions of Applicable roller coating.

Background of the invention

A large number of publications are known that describe containers for paints and other compositions of coating, some of which have been especially designed to accommodate compositions intended to be applied on a surface with the help of a roller. Examples of publications referring to containers for compositions of Coating are as follows:

- The German patent application DE-1039419 (reflecting a paint container with a grid that seems to "float" on the paint; the container is configured to allow the application of paint with a roller.

- DE-U-1816255 describes a cylindrical container for compositions of lining with a top opening on whose edge it has placed a type of drainer on which you can remove a excess paint absorbed by a brush.

- DE-A-2544990 describes a cylindrical container for compositions of covering that presents a step under the opening, on the one that can support or drain a brush.

- DE-U-8502960 and DE-U-8513250 describe grilles for Remove or roll. In DE-U-8513250 you look at a grid applied to the upper edge of a container for a coating composition.

- DE-U-20011439 describes a cylindrical container that includes a unit with a bottom that can be a grid and that extends over the container surface so that a space is established that It can accommodate a brush or roller.

- FR-A-2087688 reflects a container for a coating composition that includes, in correspondence with its upper opening, some plates inclined on which brushes and rollers can be drained.

- FR-A-2299167 describes a cylindrical container with a grid in the area of its opening.

- FR-A-2705281 describes a system for draining brushes that can be coupled to the opening of a cylindrical container for painting.

- FR-A-2725696 describes a container for coating compositions that comprises a container housed on top of another container, so that a composite container is formed that can host two different compositions.

- Patent or application publications of GB-616926 patent, GB-A-2225309, US-A-2698450, US-A-3044096, US-A-4547926, US-A-4868232, US-A-5085317, US-A-5123576, US-A-5283928, US-A-5303839, US-A-5546628 and US-A-5746345 describe others systems related to this type of containers.

- EP-A-1293360 and EP-A-1297972 describe containers for roller coating compositions, having the containers a substantially rectangular top opening and sized to allow a roller to be inserted into the corresponding container. The containers described in these documents are equipped with grilles or grills to eliminate the excess coating composition of a roller. In these containers, the rack is placed below the opening and divide the container into an upper and lower part, being the upper part defined by the opening and the grill; the part Bottom may contain the coating composition. The grid it crosses part of the container but leaves an access for the roller beyond the grid.

The grid is part of a body that is mounted on the upper edge of the container and on which the container lid

This solution may involve certain problems, since the grid has to be part of a body complex that also has to be manufactured with very large dimensions exact, so that it can fit properly on the mouth of the container. On the other hand, the incorporation of the grid to the vessel is complex, since it requires the body to fit, of exact form, on the periphery of the mouth of the container.

Therefore, an objective of the invention is provide a system that allows draining a roller that has been immersed in a coating composition, which has a simple structure and that can be easily coupled to a container.

Description of the invention

A first aspect of the invention relates to a container for a coating composition (for example, a paint composition, or similar) applicable with roller, which understands:

a container body (with walls and bottom) that defines a space to accommodate a coating composition and that it has an upper opening delimited by an upper edge of the container body;

a cover for closing said upper opening; Y

a tray comprising a frame that presents a configuration substantially complementary to the section transverse of the container body in correspondence with said upper opening, so that the frame can be introduced (from more or less tight shape) in the body of the container through said upper opening to a coupling position (in the that the frame can take a position substantially horizontal).

The tray also comprises a surface with through holes extending into the frame (for example, from a shorter wall of the frame and along part of two walls longer in the frame, for example, between 30% and a 70% of these walls) and that is configured so that, with the frame located in the coupling position, said surface divide the container body into a lower area to house the coating composition and in an upper area, extending said surface only partially through the container body so that it leaves a free space or opening (for example, delimited by a free edge of the surface, by one more wall short of the frame and by two sections of the longest walls of the frame, or by said free edge of the surface, by one more wall long of the frame and for two sections of the shortest of the frame) so that an application roller of the composition of lining can be introduced in the lower area from the upper area through said opening. This surface can serve to "drain" a roller, making the roller roll on said surface once the roller has been submerged in the coating composition through the opening mentioned.

According to the invention, the walls of the container body have an internal configuration so that the frame can be introduced through the upper opening and be leaning on body walls in an area below the edge upper body of container. That is, the frame does not fit on the upper edge of the container body, but it is coupled on the inner wall of the container body, lower than the top edge

This allows easy tray installation in the body (just enter with an orientation similar to the one it will adopt in its coupling position, namely normally a horizontal orientation, and then be lowered to "lean" on the configuration of the internal walls of the container body; it is not necessary to "couple" it on the upper edge) and allows for certain "variations" or "tolerances" in the dimensions of the body and the tray, without preventing the tray from adopting its correct position.

The internal configuration may comprise a internal step in the walls of the container body, being said step at a distance from the upper edge of the body of container (for example, between one and ten centimeters from the edge higher). In this way, the tray can rest on the step without having to interfere with the upper edge of the body, on which the lid will have to be attached.

The frame can comprise a flange or flange configured to be attached to the internal configuration of the walls of the container body, for example, on a step or Similary.

The container body may have a section substantially rectangular transverse (something that can be advantageous in the case of a container for compositions of coating that are applied with roller), for example, a configuration with four substantially straight walls joined by rounded corners.

The free space or opening left by the surface with holes can have a configuration substantially rectangular (to facilitate, for example, the passage of a roller to the lower area).

The surface with through holes may have a projection in the horizontal plane, parallel to the bottom of the body of container, which has a surface that corresponds to between 30% and 70% of the surface of the internal cross section of the container body, at a height corresponding to the position of coupling. This is guaranteed, at least in containers with the sizes commonly used for these cases, an opening large enough to allow a easy access of the roller to the lower area, while maintains a surface with holes large enough to allow the roller to roll comfortably over the surface so that excess paint or other is removed composition absorbed by the roller.

In the coupling position, the surface with through holes may have an inclination between 0º and 30º with respect to the horizontal plane, for example, an inclination of between 5th and 30th (something that can be comfortable when you want drain the roller), although other ones are also possible surface orientations.

The container body, the lid and / or the tray They can be plastic.

The lid can be configured to engage over the upper edge of the container body.

The tray may additionally comprise a separation element coupled to the tray so that it can be manually removed, so that said separation element close at least the opening in the tray (which will allow the passage from the roller to the lower area), so that the tray can serve as a lodging to house objects without these objects they can fall to the lower zone through said opening.

The separation element may comprise a flexible element attached to the frame so that with the tray in its coupling position, said flexible element isolates a part bottom of the container with respect to an upper part of the container. For example, the flexible element may be attached to A bottom part of the frame.

The flexible element can be attached to the frame by heat welding.

The flexible element can be a sheet of plastic.

The flexible element may be provided with a tab to facilitate the removal of the flexible element and / or the tray by a user.

Another aspect of the invention relates to a kit of application of a coating composition, comprising a container according to what has been described above, as well as at least an application roller of a coating composition, housed in the tray.

The kit can also include other tools, for example, a brush, masking tape, paint or other coating composition, etc.

The incorporation of these elements in the tray It can be especially practical when the tray is equipped of the separation element discussed above, which allows to isolate the arrival part (which houses the tools) of the lower zone (where is the coating composition).

Preferred Embodiment of the Invention

As can be seen in Figure 1, the container of the invention comprises a container body 1 with walls 13 and bottom 15 (see figure 3) defining a space for housing a coating composition and having an opening upper 11 delimited by an upper edge 12. The body has a cross section with substantially rectangular configuration (basically, rectangular but with rounded corners). By another part, the container comprises a lid 2 to close the top opening 11 (this cover can have any configuration conventional and is coupled on top edge 12, as is usual in the sector) and a tray 3 comprising a frame 31 that presents a configuration substantially complementary to the cross section of the container body 1, ie the tray It also features a rectangular configuration with borders rounded and dimensioned so that it can be introduced through the upper opening. In this way, the frame can be introduced into the body of the container through the opening upper to a coupling position (figures 2 and 3).

The tray has a surface 32 with through holes 33 extending in the frame (between one of the shorter walls and two sections of the longer walls) and that it is configured so that, with the frame located in the position of coupling, this surface divides the container body into a lower zone 1A to accommodate the coating composition and in an upper zone 1B. Now the surface 32 extends only partially through the container body, so that leave an opening 34 for a roller to apply the coating composition can be introduced in the area lower from the upper zone. In the illustrated embodiment, the opening 34 to access the lower zone 1A is facing the shorter side of the cube, but obviously there is also the possibility of facing the longest side of the cube; in the first case a more or less square opening 34 could be available, and in the second case you could have a more landscape opening, for example.

To hold or hold the tray in position coupling, the walls 13 of the container body 1 they have, at a distance from the upper edge 12, an internal step 14 and the frame comprises a flange 35 configured to be attached on said step (figures 2 and 3).

The opening 34 has a configuration substantially rectangular.

The surface 32 with through holes 33 has a projection in the horizontal plane, parallel to the bottom of the body of container, which has a corresponding surface approximately 50% of the surface of the cross section internal of the container body. In this way, there is enough surface to "drain" the roller comfortably, while there is an opening 34 wide enough to allow the roller can be comfortably immersed in the housed composition in the lower zone 1A. Moreover, surface 32 with through holes 33 has a slight inclination (approximately, on the order of 10th) to make the part of the composition that has "drained" on the store surface to flow back towards the lower zone.

The body, lid and tray can be of plastic.

On the other hand, a sheet of plastic 36 welded to the bottom of the frame 31 of the tray (see figure 4) so that with the tray on its coupling position, this plastic sheet isolates a part bottom of the container (the bottom zone 1A) with respect to a upper part of the container (upper zone 1B), see the Figures 2 and 3. The plastic sheet is provided with a tongue 37 (see Figures 2-4 and 6) to facilitate the removal of the flexible element and / or the tray (3) by a Username.

In figure 6 you can see a kit or set which, in addition to the container, includes a roller 50, a brush 51 and a roll of duct tape 52. Due to the sheet of plastic, these items can be delivered and transported housed inside the container, on tray 3, without being in contact with The coating composition.

In this text, the word "understand" and its variants (such as "understanding", etc.) should not be interpreted excluding, that is, they do not exclude the possibility that described include other elements, steps etc.

On the other hand, the invention is not limited to the specific embodiments that have been described but also include, for example, the variants that can be made by the expert medium in the field (for example, in terms of the choice of materials, dimensions, components, configuration, etc.), inside from what follows from the claims.
