v Application October 25, 1957, Serial No. 692,361- 3 Claims. Cl. 220-42 7 V This invention relates to improvements in paint cans and the like and particularly to improved closures for same.
It is an object of this invention to provide an improved container and closure for paint with which excess paint may be removed from the paint brush by drawing the brush across the container rim without the paint running over onto the container exterior.
More particularly it is an object of this invention to teach a paint can construction which includes a channelshaped ring within the paint can having paint drain holes which drain into the can, and a ring gasket having lugs which project through the drain holes for sealing purposes when the gasket is compressed between the channel ring and a cooperating annular projection on the paint can cover, thereby providing an airtight closure.
Other objects and advantages will be apparent from the specification and claims, and from the accompanying drawings which illustrate an embodiment of the invention.
In the drawings:
Fig. l is an external showing of a paint can utilizing my invention.
Fig. 2 is an enlarged fragmentary cross-sectional view showing through my closure means.
Fig. 3 is a top plan view of a paint can shown in Fig. 2, drawn on a somewhat smaller scale, utilizing my closure means with the cover unit and gasket removed to illustrate the paint drain holes.
Fig. 4 is a partial cross-sectional view taken on line 4-4 of Fig. 3 showing my paint can with the cover unit and gasket removed, and with a paint brush depicted as being drawn across the inner lip so that excess paint either drops back into the can directly or drains back into the can through the paint drain holes in the channel ring;
Fig. 5 is a top fragmentary view of my closure gasket illustrating the sealing lug plurality; and
Fig. 6 is a fragmentary schematic view showing a preferred shape of the gasket lug.
Fig. 1 shows a typical paint can 10 which is a cylindrical form and comprises a hollow cylindrical portion 12 which projects upwardly from and is attached to a circular base 14. Handle 16 is pivotally attached to diametrically opposed sides of the cylindrical side wall portion 12 through journal connections 18. Hollow portion 12 is open at its upper end 20 and receives a circular cover 22 (Fig. 2) to form a completely enclosed paint container.
Referring to Fig. 2, it will be noted that the container 10 includes a top rim portion 24 which is secured to the open upper end of the hollow portion 12 of the can 10. The rim 24 comprises an upwardly opening channelshaped ring 26 which may be described as of substantially U-shaped cross-section and which extends around the full circumference or periphery of the can. A rounded lip 30 projects inwardly from and around the inner periphery of the channel ring 26 and provides an edge across which the paint brush bristles B may be drawn, as shown in Fig. 4, to remove excess paint therefrom.
As shown in Figs. 2, 3 and 4, a plurality of paint drain holes or slots 32 are provided in the lower extremity 34 of channel ring 26. These paint drain holes 32 permit excess paint which has been accumulated in the channel ring 26 by the drawing of the paint brush bristles B across rolled lip 30 to drain back into the hollow section 12 of the paint can 10.
Preferably a removable resilient gasket 36 fits into the lower extremity 34 of the channel ring 26. The gasket ring 36 carries a plurality of lugs 38 which are downwardly tapering. and spaced to project downwardly through the paint drain slots 32, as shown in Fig. 2, and to contact the slots 32 in fluid sealing engagement.
The gasket 36 preferably is formed of resilient material such as rubber, polyethylene, Teflon, nylon or the like, and with the cover 22 seals the container 10.
The removable circular cover member 22 includes a downwardly projecting annular ring 40 of substantially U-shaped cross-section. The ring 40 is so shaped as to be received in cooperating surface-to-surface sealing engagement in the groove 26 so that its lower extremity 42 cooperates throughout its full periphery with the lower portion 34 of the channel ring 26 to compress the gasket 36 therebetween and form an air tight closure for the paint can 10 when the channel ring 40 of the cover 22 is pressed firmly into the channel ring 26.
The gasket 36 provides a tight seal which prevents air leakage into the can 10 and the formation of scum on the paint in the can and also prevents the formation of paint film across the openings 32.
The gasket 36 is removable from the groove 26 after the cover 22 and may be readily replaced when the can is to be rescaled.
It will be understood that the particular construction described is adaptable to containers other than paint cans.
Although only a single embodiment of the invention has been illustrated and described herein, it will be apparent that various changes and modifications may be made in the configuration and arrangement of the component parts without departing from the scope thereof.
What I desire by Letters Patent is:
1. A fluid container of the paint can type comprising a hollow cylindrical portion open at its upper end, an upwardly opening ring of substantially U-shaped cross-section extending around the periphery of and projecting inwardly from said upper end of said hollow cylindrical portion and having at least one drain orifice in the lower extremity thereof, a resilient ring gasket engaging the entire lower extremity of said U-shaped ring and having a downwardly projecting lug extending through and engaging said orifice in fluid sealing relation, and a circular cover member having an upwardly opening ring of substantially U-shaped cross-section extending around the periphery thereof and projecting outwardly therefrom and shaped to be received in and snugly engage said hollow cylindrical portion U-shaped ring in sealing engagement such that said ring gasket is compressed between the lower extremity of said U-shaped rings.
2. A fluid container of the paint can type comprising a hollow cylindrical portion open at its upper end, and upwardly opening channel shaped ring of substantially U-shaped cross-section extending around the periphery of and projecting inwardly from said upper end of said hollow cylindrical portion and having a plurality of fluid drain slots in the lower extremity of said channel, a resilient ring gasket engaging the entire lower extremity of said channel and having a plurality of downwardly projecting and tapering lugs each extending through and tightly engaging one of said slots in fluid sealing relation, and a circular cover member having an upwardly opening channel shaped ring extending around the periphery thereof an aun and projecting outwardly therefrom and shaped to received in :and snugly engage said hollow portion channel ringin sealing engagement such that said ring gasket is compresed between said channel rings throughout their lowerextremities. j
3. A fluid container closure unit comprising a firstupwardly opening channel shaped ring extending around the periphery offend projecting inwardly from and attached to the open top of the container having a pluralityof fluid drain slots in thechannel lower extremity and having a downwardly directed roll lip around the inner periphery thereof, a removable resilient, flat ring gasket engaging the entire lower extremity of said channel ring and having at least one downwardly projecting and tapering lug extending through and tightly engaging one of said slotsm mun simmers in fluid sealing relation, and a circular cover member having a second upwardly opening channel shaped ring extending around the periphery thereof and projecting outwardly therefrom and shaped to be received in and snugly engage said first channel shaped ring in sealing engagement such that said ring gasket is compressed between said channel shaped rings throughout their lower extremities.
