Figure 10 shows how the trays of paint shown in figures 7 and 8 can be arranged on the container.

Figure 1 is a perspective view of a plastic container 1, separated from across, which is provided, in the top part of a cover 4 made of plastic. Preferably the container has a volume such that it can contain from 1 to 20 liters of paint or varnish, while said container simultaneously houses a roller tray of paint according to the invention; and in which the roller tray of paint is arranged at a level above the surface of Paint liquid / varnish.

As shown in Figure 1, the plastic container 1 comprises a lower part 5 of vessel that extends into a surrounding wall 5 that it has, opposite the bottom, a free edge 7 with a flange 8 and defining the mouth of the plastic container. He flange 8 is intended to be applied immobilizingly to pressure with complementary pressure operating means on cover 4 in a conventional manner. Therefore, the container is defined by the bottom part 6, the side walls 5 and the edge 7 free. As will appear from the figure, the container 1 of plastic is configured with pairs of opposite parallel sides, so the plastic container, seen from above, can be rectangular or square; alternatively the container of Plastic can be cylindrical or conical.

In relation to the mouth of container 1 of plastic, a paint roller tray 10 according to the invention It is arranged on top of the plastic container.

In figures 2, 3 and 4 it is shown in detail the paint roller 10. As shown in Figure 2, the paint roller tray comprises a bottom with a lower face 11, in which a surrounding wall 15 extends from the bottom part 12 and which is bounded by an edge 18 free opposite the lower part 12, and so the edge 18 free defines a top opening in the roller tray 10 of painting.

The bottom 11 of the roller tray paint is set with a single curvature that extends from the free edge 18 of one side 15 with an inclination descending in an opposite direction 15. The "single curvature" expression as used herein document is intended to designate a surface that has a curvature in a first direction and essentially no curvature in a direction perpendicular to said first direction. The hollow so formed will be directed upwards in the use situation. In a lower area of the lower face 11, in which the inclination has decreased and continues in a lower level development 19 or a development 19 essentially flat bottom, bottom 12 comprises a lower opening 21 intended to transport paint from the container and up to the lower face 11. He paint transport will preferably take place by means of a paint roller (not shown) that is transported down to through the opening 21 and immersed in the paint, after what which is worn on the underside, in which the roller of paint slips rolling on the underside. Preferably the paint roller will drain a full turn over the lower face 11.

For example, the lower face 11 can be set up with a development that defines a section of a circle or A section of an ellipse.

Advantageously, the lower face 11 is it will provide or be configured with a certain number of projections 16, 17 with the shape of a breasts, flanges or nerves and that serve the purpose of providing increased friction between a paint roller and the lower face 11 and therefore to prevent the roller from Paint slip during runoff.

The tray of previously described paint roller in relation to an embodiment of the invention, in which the paint roller tray is disposed within the plastic container However, according to the invention there is nothing that prevents the paint roller tray from being configured with fixing means (not shown) as wall extension 15 side on the bottom side of tray 12, so you can fix on the free edge 7 of the container wall 5. When the paint roller tray 10 is disposed on the container 1 plastic and roller tray fixing means paint are lowered over the free edge of the wall of container, the flange on the free edge will be applied so pressurized immobilizer with the fixing means of the tray paint roller. Correspondingly, at edge 28 free, the side wall 15 of the paint roller tray is it will have a flange that can be applied immobilizingly to pressure, in a conventional manner, with operating means at complementary pressure on a lid.

The container described in the context of the figures 5-10 can be considered as based on a further development of the paint roller tray described in the context of figures 1-4.

However, it should be noted that the principles described in the context of figures 5-10 are they can use completely independently of the principles described with reference to figures 1-4. So in general the container described with reference to the figures 5-10 solves several of the problems identified  during the practical use of the packaging solutions taught in the U.S. Patent No. 5472111 and European Patent No. 1293360, respectively.

In Figure 5, reference number 101 Show a plastic container. The container is intended for contain in particular paint, varnish or other liquid products similar to be applied to a surface by means of a paint brush or in particular a paint roller. He container 101 has a wall and a bottom that combine to define a hosting space for the content of the container 101, and opposite to the bottom has a opening bounded by the upper edge of the wall. He container can be round, but preferably it is approximately square or approximately rectangular, which means that it will appear as shown with approximately sides opposite arranged parallel, because that form is particularly suitable when the container 101 is to be used in relationship with a paint roller for content application of the container on a surface.

The container 101 is also shown in the figure 6, from which it will emerge that, below its edge 101 ' upper, the wall of the container 101 has a skirt 104 surrounding protruding outward and a junction area that is extends along the opening, in the embodiment shown in recess shape 120 for the optional connection of either a cover 103 of plastic or a tray 102 of plastic paint, the which will both be subject to further description ahead. Together with tray 103 and paint tray 102, the container 101 forms a container intended to be supplied to the end user at a point of sale with paint, varnish or product corresponding content in the container 101 below the lid 103.

In Figure 5 the container 101 is shown with the paint tray 102 fixed to the joining zone 120 of the container 101. It will be understood that Figure 5 shows the tray of paint in a position of use, in which the user has access to the contents of the container 101. As shown in Figure 5 paint tray 102 is configured with a part 106 bottom which has a passage opening 108 delimited by an edge 128 peripheral The lower part 106 is delimited by a wall 107 that extends upwards that can have a height of preferably between about 2 cm and about 7 cm.

The wall 107 of the paint tray 102 follows essentially the contour of the wall of the container 101, the lower part 106 a face of a single curvature (not shown), its upper zone being located as far away from the opening 108 as described with reference to figures 1-4. The opening 108 is preferably elongated and preferably rectangular and is preferably located in proximity to or in direct contact with the wall 107 of the paint tray 102.

In order to ensure a seal between the paint tray 103 and container 101, it is preferred that the paint tray 103 is configured so that it is in contact intimate with the upper edge 101 'of the container 101 in the position of use shown in Figure 5, for example so that the wall 107 be in contact with the upper edge 101 'along the entire expansion of it. When the container 101 is essentially rectangular as shown in figure 5, tray 102 of painting will also have approximately parallel sides and in that case the opening 108 will preferably be configured near or attached to one of the short sides of the paint tray 102.

While using the paint tray 102, the bottom part 106 forms a runoff face for a roller of paint or a paint brush that dipped into the liquid contained in the container 101 through the opening 108 with views to remove excess liquid from the paint roller by of the user rolling the paint roller along the bottom 106. To this end, the lower part 106 may be provided of protrusions 109 in the form of nerves that facilitate runoff of excess paint from the paint roller or brush paint, and wall height 107 is set preferably so as to avoid as much as possible that the paint on the paint tray 102 splashes past the edge top of paint tray 102.

Figure 6 also shows that the tray of paint has a tab 105 that extends down, with a ledge 111 oriented inward. This ledge 111 oriented inwards is intended for application with zone 120 of junction on the container 101, preferably an application of pressurized immobilization, whereby tray 102 of paint can be fixed in the position of use shown in the figure 5. To this end, the junction zone 120 is configured to be complementary to projection 111. The drawing shows several 105 separate tabs, more specifically two of them, arranged opposite each other along the sides of the paint tray 102 constituting, in the embodiment by way of example, two short sides of the paint tray 102, but there is no nothing that prevents tab 105 from spreading all over the circumference along the wall 107 in order to enable therefore the application with the zone 120 of union, configured of complementary way, along the entire upper edge of the vessel wall 101.

Figure 6 also shows cover 103 intended to seal the contents of the container 101 with respect to the Exterior. To this end, the lid 103 has a partition wall 103 ' horizontal and a surrounding wall that extends upwards and downward from the wall 103 'of partition wall whereby a recess 130 upper and recess 132 lower. On the bottom the surrounding wall forms a surrounding projection towards the interior that is seen from the outside on the wall as a recess 122 surrounding interior, and this projection is configured so that the cover 103 is able to be applied immobilizingly to pressure with the junction zone of the container 101 because the projection it is pressed into recess 120.

As shown in Figure 6, the form of the cover 103 at the top corresponds to the shape of the area 120 for joining the container 101. Thus, the lid 103 has a zone 120 'junction. Therefore, the paint tray 102 can be fixed to the cover 103, while the cover 103 is on the container 101, that is, before opening the container, because the ledge 111 of the paint tray is caused to be applied pressurized immobilizer with the 120 'junction zone of the top. When the container is to be opened, the lid 103 is removed, by example by the user, entering the fingertips by under the bottom edge of the lid 103 in an area of the skirt 104 of the container with the recess 112 and lifting upwards. Before the cover 103 is removed, the paint tray 102 is can be optionally removed by lifting paint tray 102 upwards and, in order to facilitate such separation, the pressure immobilization application between tray 102 of paint and lid 103 may preferably be easier to release that the pressure application between the cover 103 and the container 101, where sealing requirements put requirements superior to the resistance of the application. Wall 107 of the paint tray 102 preferably follows the contour of the wall of the container 101, and in particular the contour of the skirt 104, but extends at most to an extension imaginary up skirt 104, so several of the containers shown can be arranged next to each other being the respective skirts attached to each other.

It will be understood that the invention provides a container, in which all constituent components can be assembled by the supplier, and in which the user can verify easily that the paint tray is delivered simultaneously with the recipient. In addition, the invention facilitates the mixing of a original contents of the container 101 with for example an ink, and during painting procedures it is quite certain that the container relies reliably with little risk of spillage due to a tip of the container 101, which is a problem of package shown in US 5472111, in particular when only some paint remains in the container simultaneously with that the paint roller is rolled in a direction towards the part of the paint tray that extends beyond the side of the container.

Figure 7 shows a configuration alternative of the container in which, if desired, there is the option of completely obviate the need for a separate lid between the paint tray 102 and container 101. Using that container the paint tray 102 thus has a lid 118 configured to be fixed detachably to cover the opening 108. Although not shown, the paint tray 102 preferably has a ledge 111 extending around the entire wall 107 of the paint tray 102, so it can be set an intimate cooperation with the junction zone 120 of the container 101, so the container 101 can be delivered with content to the end user, guaranteeing the sealing of the container by means of tight connection between paint tray 102 and container 101 and between the lid 118 and the paint tray 102, respectively. When the user will apply the content of the container 101 on a surface, lid 118 is removed and transports a paint roller through opening 108 such as described above. After use, the cap is applied 118. An advantage of this package is that the Need for a separate lid.

Figure 8 shows a further embodiment of the invention. That embodiment comprises a separate lid as described above with reference to figures 5 and 6, and a paint tray, from which different are shown configurations in figures 9a and 9b. Paint tray shown in figure 9b is provided with openings, whereby the paint and the like on the paint tray can drip to the inside of the container The paint trays shown on the Figures 8 and 9 are configured to join on the inside in the upper recess 103 'of the cover 103, for example by means of an effect under pressure, said paint tray 102 and said lid 103 having complementary coupling means that allow a union reliable separable from paint tray 102 such that it shows that it is visible to the end user. In that embodiment, paint tray 102 may have such dimensions that in the position of use is to be introduced inside the container 101, as shown in Figure 10, for example up to one depth of 4-8 cm below the edge 101 ' upper of the container 101, where the container can have a surrounding step that allows a detachable tray support 102 of paint, optionally by using joining means complementary, so you get a real fixation of the paint tray 102 in the use position shown in the figure 10.
