Abstract
A sheet of flexible material may be hand formed into a selected, conic, funnel shape; maintained in that shape while utilized as a funnel; then disposed of. A kit containing a quantity of such sheets provides ease of transport and ready access to a multiplicity of disposable funnels of various selected sizes.
Claims7
In a disposable funnel comprised of a generally rectangular, flexible, planar material formable by a user into a funnel shape and having adhesive affixed to said material for making adhering contact to a selected, relatively broad porton of said material to maintain said material in a user-selected funnel shape, the improvement for efficiently reducing the amount of adhesive necessary to maintain said user-selected funnel shape, said improvement comprising:
- said adhesive being a relatively narrow adhesive strip, coupled obliquely to said material so as to lie in a generally straight line on a surface of a user-selected funnel shape, rather than forming a spiral line about the surface of said funnel shape, thereby efficiently reducing the amount of adhesive required to maintain said material in said user-selected funnel shape.
Disposable funnel means comprising:
- a sheet of nominally planar material of sufficient flexibility to be hand rolled to a user-selected funnel shape, said sheet being generally rectangular in shape and having at least three sides, one of which is oblique the other two;
- and
- adhesive means coupled to said sheet in a strip along the side oblique of the other two to generally lie on a straight line on a surface of said sheet, as opposed to lying on a curved, spiral path on the surface of said sheet, when said sheet is rolled to a user-selected funnel shape.
