Bucket funnel

Abstract

A bucket funnel has a funnel body which clips onto a bucket with a top flange. The funnel body has a semicircular lower edge which has about the same radius of curvature as the bucket, but only extends about halfway around. There are outer tabs with inward facing channels at the ends of the lower edge of the funnel body to clip into the flange of the bucket. There is also a spring loaded release clip at about the middle of the lower edge to clip onto the outer flange of the bucket. An inner apron extends down from the lower edge of the funnel body to form a seal against the inner wall of the bucket. An interchangeable conical nozzle attaches to the funnel body for dispensing of fluids of various viscosities, such as glue, paint or fresh concrete.

BEST MODE FOR CARRYING OUT THE INVENTION

(9) The best mode for carrying out the invention describes non-limiting exemplary embodiments. Any individual features may be combined with other features as required by different applications for at least the benefits described herein. As used herein, the term about means plus or minus 10% of a given value unless specifically indicated otherwise.

(10) FIG. 3A is an exploded side view of an alternative bucket funnel 300 mounted on a bucket 202 (shown in partial view). The illustrated nozzle 302 is from an Albion caulking gun system. The nozzle is mounted on the funnel body 310 using a threaded collar 304 which engages a threaded hopper opening 308 extending from the funnel body. The nozzle is sealed to the hopper opening with an elastomeric O ring 306.

(11) The nozzle has an axis 332. The axis may be inclined at an angle 340 with respect to the lower edge of the funnel body 321. The inclination angle may be in the range of 20 degrees to 60 degrees. A suitable inclination angle is about 30 degrees.

(12) An inner apron 312 extends downward from the funnel body. An outer tab 330 is on each end of the lower edge. The forward vertical edge 334 of an outer tab is backward of the proximate backward vertical edge 332 of the inner apron. Thus there is a flexible arm 336 attaching each outer tab to the funnel body. This allows the outer tabs to be flexed out when installing or removing the bucket funnel on a bucket.

(13) FIG. 3B shows a cross section of the inner apron 312. The inner apron comprises an apron rim 322 with an apron rim gasket 324 depending underneath. The inner apron further comprises a back plate 326 extending downward from the inner edge of the apron rim. A flexible skirt 328 is attached to the back plate. The flexible skirt is directed outward. This forms a flexible skirt standoff 338 between the outer wall 342 of the back plate and the inner wall of the bucket when the bucket funnel is installed. A suitable standoff is in the range of 1 to 10 mm. When the funnel body is placed on the bucket, the gasket forms a seal with the rim of the bucket and the flexible skirt forms a seal with the inner wall of the bucket. A surprising advantage of the flexible skirt in combination with the standoff of the back plate of the apron from the inner wall of the bucket is that an adequately tight seal can be formed with the inner wall of the bucket even if a certain amount of solid deposits are on the inner wall of the bucket. The deposits could be solidified paint, glue, concrete, etc. The standoff gives clearance to the deposits and the flexible edge conforms to variations in the deposits' thicknesses.

(14) The bucket funnel can be made of appropriate materials, such as molded plastic, metals and elastomers. The plastics should be compatible with the materials that will be dispensed from the bucket. The materials that might be dispensed may include glues, sealants, fresh concrete and dry powders (e.g. sand).

(15) FIG. 4 is a top view of the funnel body 310 of FIG. 3 mounted on bucket 202. The bucket comprises a handle 402. The semicircular lower edge of the funnel body 321 spans a rim angle 404 of about 180 degrees or less. This allows easy installation and removal. The rim angle should be large enough so that the fluid in the bucket will be captured in the funnel body when the bucket is tipped. A rim angle as small as 120 degrees is suitable. A rim angle of about 145 degrees is suitable. The inner apron 312 has a semicircular shape when viewed from above. The semicircular shape of the inner apron spans an apron angle 406 that is less than the rim angle. The apron angle should be large enough so that the skirt on the apron will keep fluid from flowing out underneath the flexible arms 336 attached to the outer tabs 330. An apron angle as low as 90 degrees is suitable. An apron angle of about 110 degrees is suitable.

(16) FIG. 5 is a cross section of an outer tab 330 of FIG. 3 mounted on the outer flange 204 of a bucket. The outer tab comprises an inward facing tab channel 502 that is dimensioned to fit around the outer flange of the bucket. The outer tab also comprises a tab handle 504 for pulling the tab away from the outer flange when installing or removing the bucket funnel on a bucket. The outer tab handle may be inclined down and outward at a flare angle 506. A suitable flare angle is in the range of 0 to 60 degrees.

Example 1

(17) FIGS. 6 and 7 are illustrations 600, 700 of a worker 612 pouring fresh concrete 616 from a 5 liter bucket 620 through an alternative embodiment of a bucket funnel 630. In FIG. 6, the worker has just interrupted filling a first channel 605 cut in a first concrete slab 602. The worker is joining the first concrete slab to a second concrete slab 604. The first channel is cut from the first slab to the second slab. A second channel 606 is similarly cut from the first slab to the second slab. A steel bar 608 which traverses the slabs has been placed in each of the channels. Fresh concrete is being poured 610 into each channel to lock in the steel bars thus joining the slabs together.

(18) The bucket funnel comprises a nozzle 634 mounted on a funnel body 632. An inner apron 648 extends down from the funnel body. A flexible skirt 650 extends outward from the inner apron to press against and form a seal with the inner wall 654 of the bucket. The flexible skirt forms a seal despite the presence of deposits 656 of partially hardened concrete on the inner wall. The outer tabs of the funnel 646 engage the outer flange of the bucket 624. The outer tab 646 is shown as a dotted line. The outer tab is connected to the funnel body by a flexible arm 644. A reinforcing bar 652 has been added to each flexible arm for extra strength. The release clip is not visible in this view, but engages the outer flange of the bucket underneath the nozzle 634. The nozzle has a relatively wide opening 636 of about 3 cm to allow a controlled amount of fresh concrete to flow therethrough when the bucket is tipped over.

(19) The worker has already made a first pass 614 of pouring concrete into the first channel 605. After the first pass, there was about 1 cm of clearance 616 between the top of the fresh concrete and the top of the channel. The worker then began a second pass 618 to finish filling the channel to its top edge 642. The worker has just tipped the bucket back to stop the flow of fresh concrete.

(20) Referring to FIG. 7, the bucket 620 is tipped forward so that the bucket funnel 630 and nozzle 634 are pointing down. The worker 612 is in the process of filling the second channel 606 with fresh concrete 616. The fresh concrete is flowing into the bucket funnel at about the rate it is flowing out of the nozzle thus forming a stable head 702 and hence steady flow. The worker adjusted the tipping angle of the bucket to keep the head below the rim 704 of the bucket funnel.
