Abstract
An insert for a drinks container to assist in the promotion of a foamy or creamy head on beverage comprises a chamber (30) having two openings (31c) therein joined together within the chamber to form a tube (32), said tube having two venting holes (33a and 33b) in the sidewall thereof to provide communication between the inside of the chamber and the tube. The insert (I) is located in a container (C) after filling with beverage (B) so that one lower venting hole (33b) is below the surface of the beverage, and the other above it. Subsequent pressurisation of the container (C) (by adding a drop of liquid nitrogen immediately prior to closure) causes an ingress of pressure through each venting hole therein into the chamber causing an introduction of both gas and beverage under pressure until the pressures in the chamber and in the container substantially equalise, upon opening the pressure drop in the container (C) causes the egress of pressure via the tube to create a jet of gas (H) into the beverage.

Claims (6)
- An insert for a drinks container comprising a chamber having at least one opening therein, a tube extending through said opening and having a reduced diameter hole in the end remote from the chamber and two-way valve on or adjacent the end of the tube within the chamber adapted to allow selective communication with the chamber, wherein the insert is placed in a container before or after filling with beverage and subsequent pressurisation of the container causes an ingress of pressure through the hole into the tube and through the valve into the chamber until the pressures in the chamber and in the container substantially equalise, upon opening the pressure drop in the container cause the egress of pressure through the valve and the tube to create a jet of gas into the beverage.
- 2. An insert for a drinks container comprising a chamber having at least two openings therein, a tube extending through said openings so that it extends out of the chamber, said tube having at least one venting hole in the sidewall thereof to provide communication between the inside of the chamber and the tube, wherein the insert is placed in a container before or after filling with beverage and subsequent pressurisation of the container before or after filling with beverage and subsequent pressurisation of the container causes an ingress of pressure through the tube and the venting hole therein into the chamber until the pressures in the chamber and in the container substantially equalise, upon opening the pressure drop in the container cause the egress of pressure via the tube to create a jet of gas into the beverage.
- 3. An insert for a drinks container comprising a chamber having at least two openings therein joined together within the chamber to form a tube, said tube having at least one venting hole in the sidewall thereof to provide communication between the inside of the chamber and the tube, wherein the insert is placed in a container before or after filling with beverage and subsequent pressurisation of the container causes an ingress or pressure through the tube and the venting hole therein into the chamber until the pressures in the chamber and in the container substantially equalise, upon the pressure drop in the container cause the egress of pressure via the tube to create a jet of gas into the beverage.
- 4. An insert for drinks container comprising a chamber having at least two openings therein joined together within the chamber to form a tube, said tube having two venting holes in the sidewall thereof to provide communication between the inside of the chamber and the tube, wherein the insert is located in the container after filling with beverage so that one lower venting hole is below the surface of the beverage, and the other above it and subsequent pressurisation of the container causes an ingress of pressure through each venting hole therein into the chamber causing an introduction of both gas and beverage under pressure until the pressures in the chamber and in the container substantially equalise, upon opening the pressure drop in the container cause the egress if pressure via the tube to create a jet of gas into the beverage.
- 5. An insert for drinks container as in either Claim 3 or 4 wherein the openings are pressed into the chamber and the tube is formed by joining the pressed edges of the openings together.
- 6. An insert for a drinks container as hereinbefore describe with reference to the accompanying drawings.
