Abstract
An apparatus for collecting insects or small objects combines a vacuum cleaner and a disposable trap made of paper and mounted in the intake orifice of the vacuum cleaner hose. a frusto-conical funnel is wedged into the mouth of the trap to secure it and to prevent its collapsing under suction of the vacuum. The trap has a flap to confine the collected items for disposal or preservation.

In combination with a vacuum suction apparatus having a substantially circular intake orifice of a certain diameter, a device for collecting items sucked into said orifice, which comprises:
- a conical trap partially inserted through said intake orifice, said trap being made of sheet-like, pliable material having a tapering angle of no more than 40 degrees, an open base having an aperture diameter greater than said intake orifice diameter, and an air-permeable area having a plurality of perforations, said perforations being sized to retain said items in said trap;
- and
- a frusto-conical funnel having at one end an inlet with an outer diameter greater than said base aperture diameter and at an opposite end an outlet with an outer diameter smaller than said intake orifice diameter, and a tapering angle no greater than the tapering angle of said conical trap, said funnel being forcibly inserted into said base aperture to wedge said trap into said intake orifice.
