Description

FIELD OF THE INVENTION

The present invention relates to liquid containers, and more specifically, to self-draining liquid containers.

BACKGROUND OF THE INVENTION

Containers can be used to hold liquids, such as paint and other liquids. A paint container generally includes a cylindrical body with a round lid that engages the body by frictionally engaging a grooved portion of the body. During use, paint can become trapped within the grooved portion, and thus wasted.

A prior solution is the provisioning of apertures within such grooves, which can allow paint to drain back into the cavity of the container body. Such provisioning can be effectuated via a tool, such as ones disclosed in U.S. Pat. Nos. 7,121,425 and 5,212,869. Notably, despite utilization of such tools and provisioning of apertures for a draining feature, residual paint can remain within such grooves and over and/or adjacent to such apertures. Accordingly, subsequent engagement of a lid can create a thin layer of paint over such apertures, with such layers drying to form a solid layer of impermeable, dried paint that can cover such apertures, which can undesirably render an aperture's draining function ineffective. The present invention remedies this deficiency.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a self-draining container.

Another object of the present invention is to provide a self-draining container that overcomes at least one deficiency within the prior art.

The present invention provides an improved self-draining container.

In an exemplary aspect of the present invention, the present invention can be formed of any one or more impermeable materials that can functionally retain a liquid. Thus, any one or more of a plastic, rubber, metal, wood, elastomer, crystalline material, man-made material, and naturally-occurring material may be utilized insofar as the resulting material is impermeable within the spirit of the present invention. And notably, different portions of the present invention can be formed of the same or different materials to the extent desired.

FIG. 1a illustrates a partial view of an exemplary embodiment of the present invention, in which a self-draining container 100 can include a main body 110 defining a cavity 111, and a lid 120. FIG. 1b provides a partial, zoomed perspective of main body 110 and lid 120 to facilitate particular elements thereof.

In an exemplary aspect of the present invention, main body 110 can include a rim 112 with an annular sealing groove 113 having a groove diameter 114 and a lower groove portion 115 with at least one aperture 116 that can allow a liquid to drain into cavity 111 that is exposed by opening 117, which is defined by rim 112. Rim 112 can be provided as an integral component of main body 110. For example and not in limitation, rim 112 can be a molded component of main body 110. However, rim 112 can alternatively be a separately attached component. For example and not in limitation, rim 112 can be glued, welded, crimped (see FIG. 3a), or otherwise attached to main body 110.

In another exemplary aspect of the present invention, lid 120 can include an annular sealing member 121 with a member diameter 122 and a lower member portion 123 having at least one protrusion 124. Notably, each protrusion 124 can be strategically sized and positioned to fit within and align with an aperture 116.

As illustrated, member diameter 122 can be complementarily-sized with groove diameter 114, such that sealing member 121 can be frictionally and sealably disposed within sealing groove 113 with each protrusion 124 passing through an aperture 116.

FIG. 2a illustrates a partial top-view perspective of an exemplary main body 110. As illustrated, an aperture 116 can be provided with a rectangular shape; however, any alternative shape(s) (such as one or more of a square, triangular, symmetric, asymmetric, irregular, or any other geometric shape, for example and not in limitation) can be provided to the extent desired and complementary to the shape and size of a protrusion 124 such that the protrusion can fit therethrough.

FIG. 2b illustrates a partial bottom-view perspective of an exemplary lid 120. As illustrated, a protrusion 124 can be provided with a rectangular shape; however, an alternative shape(s) (such as one or more of a square, triangular, symmetric, asymmetric, irregular, or any other geometric shape, for example and not in limitation) can be utilized to the extent desired and complementary to the shape and size of an aperture 116, such that the protrusion can fit therethrough.

In another exemplary aspect of the present invention, a protrusion 124 can be provided as an integral component of lid 120. For example and not in limitation, a protrusion 124 can a molded component of lid 120 and/or sealing member 121. In an exemplary aspect, a lid 120 and/or sealing member 121 can be molded with a protrusion 124 in a single mold cavity. However, a protrusion 124 can alternatively be a separate component that is attached to sealing member 121. For example and not in limitation, a protrusion can be glued, welded, crimped, or otherwise attached to sealing member 121.

In another exemplary aspect of the present invention, there can be at least one aperture 116 for each protrusion 124.

FIG. 3 illustrates a cross-section of an exemplary main body 110 and lid 120. As noted above, protrusion 124 can be provided as an integral component of lid 120, such as, for example and not in limitation, where lid 120 is produced via a molding process, such as injection molding, for example and not in limitation. However, as illustrated in FIG. 3, a protrusion 124 can also be an integral component of lid 120 by way of bending of a bendable material (e.g., a metal), such as a flange being bent along sealing member 121 and extending downwardly to form the protrusion (and optionally, as illustratively shown in FIG. 3, back up to form a protrusion with plural layers).

FIG. 4 illustrates partial cross-section view of an exemplary lid 120 having a protrusion 124 crimped thereto via a crimp element 125. As further illustrated, protrusion 124 can include a tapered portion 124a that tapers in at least one direction, which in this example is downwardly, which can assist in disposing a protrusion 124 through an aperture 116 when sealably engaging lid 120 with main body 110.

FIGS. 5a and 5b illustrate partial cross-section views of an exemplary main body 110 and lid 120 in which a protrusion 124 can include a tapered portion 124a that tapers horizontally and forms a tapered slot 124b. Accordingly, after protrusion 124 is disposed through aperture 116, lid 120 can be rotated in the tapered direction of tapered portion 124a, lower groove portion 115 can frictionally engage the protrusion between tapered slot 124b to facilitate a secured engagement of lid 120 to main body 110.

Notably, in any embodiment of the present invention, the various elements can be provided in any desired shape and/or size that are functionally compatible with the present invention as described and/or claimed, and as expressly stated, are not necessarily limited to any particular shape or size illustratively described herein. Accordingly, exemplary shapes and/or sizes can include any shape or size having one or more geometric shapes, whether having symmetric or asymmetric portions, and without shape or size limitations relative to other elements unless necessary to the functionality of the present invention.
