Beverage can drinking attachment

Claim 2

A beverage can drinking attachment comprising: (a) a substantially cylindrical body having clamping means for obtaining a liquid tight connection between the beverage can attachment and a can top positioned at a lower end of said body; (b) a disk extending substantially transverse across said body dividing said body into a drinking portion and a clamping portion, said disk having means for engaging the can top; (c) an aperture in said disk which when said can attachment is placed on the can top said aperture is alignable with a can lid opening; and (d) means located on said disk for receiving a can lid opening device, the can lid opening device remaining attached to the can top after the can is opened; said receiving means comprising a raised section for accepting the can lid opening device bent into a generally flat position when the can lid opening device is in a post-open position.

Claim 3

The beverage can attachment as claimed in claim 1, wherein said can lid opening device receiving means comprises a hood formed substantially integral with said disk, said hood receiving the can lid opening device when the can lid opening device is in a pre-open position.

Claim 4

The beverage can attachment as claimed in claim 1, wherein said can lid opening device receiving means comprises a partially cut-out raised section and a slot, said can lid opening device receiving means accepting the can lid opening device when the can lid opening device is in a post-open position.

Claim 5

The beverage can attachment as claimed in claim 3, wherein said can lid opening device receiving means accepts the can lid opening device when the can lid opening device is returned from the post-open position to a pre-open position.

Claim 6

The beverage can attachment as claimed in claim 3, wherein said partially cut-out raised section is centrally located on said disk and accepts the portion of the can lid opening device that is connected to the can lid.

Claim 7

The beverage can attachment as claimed in claim 3, wherein said slot is integral with said disk aperture, said slot being centrally located on said disk, said slot accepting a tab of the can lid opening device when the can lid opening device is in the post-open position.

Claim 8

The beverage attachment as claimed in claim 1, wherein said clamping means comprises a skirt extending from a joint between said cylindrical body and said disk, said skirt having at a lower edge at least one inwardly extending rib which engages the cylindrical wall of the can, said skirt extending substantially below the rim of the can when said can attachment is placed on the can top.

Claim 9

The beverage attachment as claimed in claim 7, including a pair of ribs.

Claim 10

The beverage can attachment as claimed in claim 1, wherein said upper cam rim engaging means comprises an annular channel which extends along the periphery of said disk, said annular channel encompassing the upper rim of the can.

Claim 11

The beverage can attachment as claimed in claim 1, wherein said cylindrical body has an upper end inner diameter that is larger than the outer diameter of a beverage can, whereby said cam attachment can fit upside down over the beverage can top.

Claim 12

The beverage can attachment as claimed in claim 1, wherein said cylindrical body has an upper end inner diameter that is larger than the lower end outer diameter, whereby a plurality of said can attachments are stackable upon each other.

Claim 13

The beverage can attachment as claimed in claim 1, wherein said disk has a protruding edge extending substantially along the circumference of said disk aperture.

Claim 14

The beverage can attachment as claimed in claim 12, wherein said disk protruding edge slants downward towards said disk aperture.

Claim 15

The beverage can attachment as claimed in claim 12, wherein said disk protruding edge has an upward extending raised lip portion on that portion of said protruding edge nearest to a wall of said cylindrical body.

Claim 16

A beverage can drinking attachment comprising: (a) a substantially cylindrical body having clamping means for obtaining a liquid tight connection between the beverage can attachment and a can top positioned at a lower end of said body; (b) a disk extending substantially transverse across said body dividing said body into a drinking portion and clamping portion, said disk having means for engaging the can top; (c) an aperture in said disk which when the can attachment is placed on the can top said aperture is alignable with a can lid opening; (d) said clamping means comprising a straight, cylindrical skirt extending from a joint between said cylindrical body and said disk, said skirt having at a lower edge a pair of inwardly extending ribs which engage a cylindrical wall of the can substantially below an upper rim of the can, said skirt extending a substantial distance below the rim of the can when the can attachment is placed on the can top whereby the can attachment provides a substantially liquid tight engagement, regardless of the shape or diameter of the upper part of the can or upper rim of the can.

Claim 17

A beverage can drinking attachment comprising: (a) a substantially cylindrical body having clamping means for obtaining a liquid tight connection between the beverage can attachment and a can top positioned at a lower end of said body; (b) a disk extending substantially transverse across said body dividing said body into a drinking portion and clamping portion, said disk having means for engaging the can top; (c) an aperture in said disk which when the can attachment is placed on the can top said aperture is alignable with a can lid opening; (d) said clamping means comprising a straight, cylindrical skirt extending from a joint between said cylindrical body and said disk, said skirt having at a lower edge a pair of inwardly extending ribs which engage a cylindrical wall of the can substantially below an upper rim of the can, said skirt extending a substantial distance below the rim of the can when the can attachment is placed on the can top whereby the can attachment provides a substantially liquid tight engagement, regardless of the shape or diameter of the upper part of the can or upper rim of the can.

Claim 18

The attachment of claim 15, wherein a lower surface of said disk includes a raised angular portion around the periphery thereof and connected to said body portion.

Claim 19

The attachment of claim 15 wherein said disk includes a raised center portion.

Claim 20

The attachment of claim 15 including a slanted portion substantially surrounding said aperture for engagement at or near the can lid opening to prevent droplets from being sucked between said disk and the can lid.

Claim 21

The attachment of claim 18 wherein said aperture includes a resilient ring therein.

Claim 22

The attachment of claim 15 wherein the drinking portion has a diameter larger than the clamping portion.

Claim 23

The attachment of claim 20 wherein the diameter of the drinking portion is substantially larger than the can diameter whereby the attachment can fit upside down over the can.

Claim 24

The attachment of claim 20 wherein a plurality of attachments are nested.

Claim 25

The attachment of claim 15 wherein said clamping portion is greater than one-third the depth of said drinking portion.

Claim 26
