Abstract

Abstract A container-opening, dispenser-type funnel has a hollow body open at the bottom to telescope over a sealed container and has a flattened closed-over top with an opening in it communicating into a tapered hollow dispensing spout, and cutter means are resiliently insertable into the body to form, aligned with the spout, spaced dispensing openings in the container by blades which pierce it and cut apertures through the container top and turn the tabs resulting therefrom downward and outward when the funnel is forced axially down over the container so that radially oppositely arranged gripping means provided in association with the cutter means can hold and seal the container to the funnel during use by tight radial engagement with the cutout tabs.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 338 words
A can-opening dispensing funnel comprising an annular skirt adapted to be positioned down over and enclose the upper sidewall portions of a can, a cover portion having a first wall portion having a flatly rounded arcuate configuration connected to the upper periphery of said annular skirt and extending upwardly therefrom above the top of the can and covering the major portion of the area of the top of the can to constitute a surface for the application of flattened hand pressure to attach the funnel to the can, said cover portion also inclUding a second arcuate wall portion connected to said first wall portion and angling steeply upwardly and outwardly with respect to said first wall portion, a tubular elongated pour spout having an enlarged inlet end connected to said second wall portion and extending upwardly and outwardly therefrom, said pour spout having a centerline forming an obtuse angle with the centerline of said skirt, said cover portion defining a chamber above and extending over the entire top of the can and essentially below said pour spout and communicating with said pour spout when the funnel is in operative position, said annular skirt having a pair of downwardly depending cutter means positioned therein, each of said cutter means having a portion thereof angularly disposed towards the vertical centerline of said skirt and adapted to pierce and then to cut openings in the can when said skirt is positioned over the top of the can and the cutter means are pressed into the top surface thereof, each of said openings providing direct communication between the interior of the can and said chamber, the inlet end of said pour spout being substantially larger than the openings provided in the can by said cutter means, each cutter means having a vertical upper surface adapted to grip the cutaway surfaces of each of the openings cut in the can so as to hold it in fixed position in the dispensing funnel for discharge of contents of the can through the pour spout.
Claim 2
Dependent Claim 338 words
A can-opening dispensing funnel comprising an annular skirt adapted to be positioned down over and enclose the upper sidewall portions of a can, a cover portion having a first wall portion having a flatly rounded arcuate configuration connected to the upper periphery of said annular skirt and extending upwardly therefrom above the top of the can and covering the major portion of the area of the top of the can to constitute a surface for the application of flattened hand pressure to attach the funnel to the can, said cover portion also inclUding a second arcuate wall portion connected to said first wall portion and angling steeply upwardly and outwardly with respect to said first wall portion, a tubular elongated pour spout having an enlarged inlet end connected to said second wall portion and extending upwardly and outwardly therefrom, said pour spout having a centerline forming an obtuse angle with the centerline of said skirt, said cover portion defining a chamber above and extending over the entire top of the can and essentially below said pour spout and communicating with said pour spout when the funnel is in operative position, said annular skirt having a pair of downwardly depending cutter means positioned therein, each of said cutter means having a portion thereof angularly disposed towards the vertical centerline of said skirt and adapted to pierce and then to cut openings in the can when said skirt is positioned over the top of the can and the cutter means are pressed into the top surface thereof, each of said openings providing direct communication between the interior of the can and said chamber, the inlet end of said pour spout being substantially larger than the openings provided in the can by said cutter means, each cutter means having a vertical upper surface adapted to grip the cutaway surfaces of each of the openings cut in the can so as to hold it in fixed position in the dispensing funnel for discharge of contents of the can through the pour spout.
Claim 3
Dependent Claim 39 words
The can-opening dispensing funnel of claim 1 in which the pair of cutter means are oppositely confronting cutting blades spaced apart in the upper portion of the skirt and in directional alignment with the axis of the pour spout.
Claim 4
Dependent Claim 64 words
The can-opening dispensing funnel of claim 1 in which the vertical upper surfaces are parallel with respect to each other and define with the adjacent sidewall of the skirt a pair of slots adapted to receive the rim of a can when each of the vertical upper surfaces is in gripping relationship with its respective cutaway surface after cutting the openings in the can.
Claim 5
Dependent Claim 62 words
The can-opening dispensing funnel of claim 1 in which each of said downwardly depending cutter means has a vertical flat portion and a tapered flat portion integrally connected thereto, said tapered flat portion being inclined towards the centerline of said skirt for a portion of it with the remaining portion extending vertically downward and forming at its free end a piercing point.
Claim 6
Dependent Claim 36 words
The can-opening dispensing funnel of claim 4 in which the edges of each said cutter means are beveled to form a cutting edge to enhance the cutting of the openings in the top of said can.
Claim 7
Dependent Claim 96 words
The can-opening dispensing funnel of claim 1 in which said cutter means comprises a cutting blade support means operatively connected to the upper portion of the inner surfaces of the wall of the skirt, and a pair of downwardly depending cutting blades attached to said cutting blade support means spaced from the wall of said skirt and each having a flat portion, a portion angularly disposed towards the centerline of the annular skirt, and a downwardly extending vertical portion terminating in a piercing point, each of said cutting blades being the mirror image of each other.
Claim 8
Dependent Claim 27 words
The can-opening dispensing funnel of claim 6 in which said inner wall of said annular skirt has means for receiving and holding said cutting blade support means.
Claim 9
Dependent Claim 36 words
The can-opening dispensing funnel of claim 6 in which said cutting blade support means is a flat plate with said cutting blades depending therefrom, said flat plate defining an opening therein between the depending cutting blades.
Claim 10
Dependent Claim 41 words
The can-opening dispensing funnel of claim 6 in which said cutting blade support means is a ringlike support member attached to the inner surface of the wall of said annular skirt and having said downwardly depending cutting blades fixedly supported thereby.
Claim 11
Dependent Claim 37 words
The can-opening dispensing funnel of claim 9 in which said ringlike support member is split to provide for spring insertion of saId support member before its attachment to the inner surface of the wall of said skirt.
