DETAILED DESCRIPTION

[0018] FIGS. 1, 2 and 3 show an example embodiment of a funnel 110 having a tube 200 extending therefrom, according to the invention. Funnel 110 comprises a collar 112 surrounding a bore 114 which defines a flow axis 116. Tube 200 comprises and inlet end 202 and an outlet end 204 (FIG. 3). Tube 200 also comprises an outer surface 218 and an inner surface 220.

[0019] As shown in FIGS. 2 and 3, the collar 112 is adapted to receive the inlet end 202 of tube 200. The inlet end 202 comprises first screw threads 206 (see, FIG. 2). The collar 112 comprises second threads 122 which are compatible with the first screw threads 206. The first and second threads 206 and 122 engage and attach the inlet end 202 to the collar 112. The first screw threads 206 may be male screw threads and the second screw threads 122 may be female. Alternatively, the first screw threads 206 may be female screw threads and the second screw threads 122 may be male.

[0020] The collar 112 and the inlet end 202 may be attached in an interference fit, as shown in FIG. 3. The outer surface 218 of the inlet end may engage a surface 123 of the collar facing the flow axis 116 (FIG. 2). The outer surface 156 of the collar may engage the inner surface 220 of the inlet end. Alternatively, the inlet end 202 may be integral with the collar 112.

[0021] A plurality of lobes, in this example four lobes 124, 126, 128 and 130, are attached to the collar 112, as shown in FIGS. 1 and 2. The lobes define a surface 132 which surrounds and faces the flow axis 116. First and second lobes 124 and 126 are positioned on one side 134 of the flow axis 116, the third and fourth lobes 128 and 130 are positioned on the opposite side 136 of the flow axis. In this example embodiment, the span 138 of the lobes 124, 126, 128 and 130, measured along a first line 140 oriented perpendicular to the flow axis 116 is greater than the span of the lobes 142 measured along a second line 144 oriented perpendicular to both the first line 140 and the flow axis 116.

[0022] Each lobe 124, 126, 128 and 130 may have a curved perimeter 146, and each lobe may also have a compound curvature, i.e., each lobe may have a curvature 148 extending circumferentially about the flow axis 116, and each lobe may have a curvature 150 extending from a perimeter 146 of the lobe to the collar 112.

[0023] As shown in FIG. 1 a handle 152 may be attached to at least one of the lobes. Handle 152 is positioned along the side of the funnel 110 having the greater lobe span 138. In this example embodiment the handle 152 comprises a tab 154 oriented transversely to the flow axis 116 and projecting away therefrom.

[0024] An example embodiment of tube 200 is shown in FIG. 4. The tube 200 may be tapered. The tube 200 comprises an outlet diameter 210 and an inlet diameter 212. The outlet diameter 210 may be less than the inlet diameter 212. Tube 200 is also curved about a center of curvature 216.

[0025] Example embodiments of the funnel with various orientations of the center of curvature 216 are shown in FIGS. 5, 6 and 7. FIG. 5 shows embodiment 230 where the center of curvature 216 may be located in a plane defined by the first line 140 and the flow axis 116. FIG. 6 shows embodiment 240 where the center of curvature 216 may be located in a plane defined by the second line 144 and the flow axis 116. FIG. 7 shows embodiment 250 where the center of curvature 216 may be located in a plane defined by a third line 226 and the flow axis 116. The third line 226 is oriented transverse to the first and second lines 140 and 144.

[0026] Example funnel 110 according to the invention is advantageously made of polymers such as polypropylene. Such materials permit an inexpensive and light weight design appropriate for one time use and disposal. In particular, when the funnels are made of polypropylene it permits them to be folded into a smaller size for economical packaging. Alternatively, funnel 110 may be reusable and may be made of metal, and other polymers that are not disposable.

[0027] The advantage of the lobed design of funnel 110 resides in its laterally extended shape which is expected to better capture lateral spray of a urine stream from the female urethra. In use, the handle 152 in funnel 110 is held between the thumb and index finger, the funnel is positioned between the legs of the user and the surface 123 is positioned beneath the urethra. When held in this manner the second and fourth lobes 126 and 130 face the posterior and the laterally extended shape of the funnel 110 afforded by the first, and third lobes 124, and 128 aligns appropriately to effectively capture lateral spray. Alternatively, in the absence of a handle, the surface opposite to surface 132 may be cupped by the fingers of the user to hold the funnel 110 in position.
