Definitions

  • the invention concerns inserts to be put in containers for drinks under pressure in order that, when the container is opened, matter is released from the insert into the drink in the container to modify the nature of that drink.
  • Inserts of a variety of types have been proposed for inclusion in cans of beer under pressure with the object of releasing gas into the beer when the can is opened and thereby to cause the formation of an enhanced 'creamy' head on the beer.
  • the known inserts have not been entirely satisfactory and are of limited applicability.
  • an insert to be put in a container for a drink under pressure in order that, when the container is opened, matter is released from the insert into the drink in the container to modify the nature of that drink comprises a vessel comprising a hollow part, closed at one end and open at the other and, slidably and sealingly engaged within the open end, a plunger part and valve means permitting only under certain relative pressure conditions inside and outside the vessel egress of matter from the vessel or ingress of matter into the vessel.
  • a drink container e.g. a can or a bottle
  • the vessel is filled with suitable matter for the desired effect and the matter should be substantially compressible e.g. a gas or a liquid together with a substantial volume of gas.
  • the gas may be any gas tolerable in the context of the drink, the container and the insert and may, for example, be air, nitrogen or carbon dioxide. Vhen the insert is in its initial condition ready for putting into the container, the gas, whether or not a liquid is also present, may be at zero gauge pressure or at a higher pressure.
  • the matter in the vessel may be only a gas or a gas together with a liquid not substantially affecting the flavour of the drink.
  • the vessel of the insert may contain a gas and a suitably flavoured liquid: for example, if the drink in the container is tonic water, the vessel of the insert may contain a gas and gin.
  • the vessel of the insert may contain a fruit juice.
  • Inserts according to the invention may be used in relation not only to a variety of alcoholic final drinks but also in relation to a variety of non-alcoholic final drinks e.g. fruit juice-based and milk-based drinks.
  • the insert may be of particular value in cases where the final drink desired is a mixture of ingredients which when mixed are of limited shelf life.
  • the valve means may include an aperture having a distinct closure member displaceable under certain relative pressure conditions inside and outside the vessel of the insert so that it then ceases to close the aperture.
  • the valve means is however provided by the vessel having a part
  • valve means comprises an element which under certain relative pressure conditions inside the vessel of the insert is broken thereby permitting egress of matter in the vessel out of the vessel.
  • the valve means comprises an element which under certain relative pressure
  • the vessel is thereby compressed to a higher pressure than that in the initial condition of the insert when ready for insertion into the container.
  • the external pressure on the vessel of the insert is suddenly reduced
  • the matter in the vessel may be at least partially discharged into the drink in the container.
  • valve means having an aperture and a 105 distinct displaceable closure member the valve opens as a result of displacement of the closure member from the aperture whilst if the valve means is provided by the vessel having a breakable part it is the breaking which creates the necessary aperture. Vhere the valve means
  • valve 110 comprises a puncturing element it is the puncturing which creates the necessary aperture and in this case it is preferred that the valve means is such that as the plunger part of the vessel is forced further into the hollow part the puncturing element of the valve means is
  • the parts of the vessel causes the valve means to operate and the matter in the vessel is at least partially discharged into the drin in the container.
  • the puncturing element of the valve means is such that when the parts of the vessel suddenly move apart as a
  • An insert according to the invention preferably has
  • the retention means should be provided by the insert having a foldable frame, attached to the vessel
  • the foldable frame is preferably so dimensioned that, when the insert is ready for insertion into the drink container, the components of the frame fit closely
  • the retention means is advantageous in that it enables the insert to be firmly held in position whilst enabling it to be readily inserted into
  • the insert should be such that at the place or places where matter in the vessel is released to the exterior of the vessel there should be a narrow channel or channels such that the insert
  • the insert should be such that the matter does not pass directly to the exterior of the vessel from the large aperture but first passes through a narrow channel or channels as just indicated. It is particularly
  • the fine channel or channels should be provided by the insert having, at the place where matter in the vessel is to pass to the exterior of the vessel, a socket in which is located a plug, the plug and/or the socket walls having a fine groove or grooves through

  • a drink can 1 has within it an insert 2 resting on the interior of the base of the can. The left hand side of the section through the
  • the 215 insert shows the insert in its initial condition i.e. as inserted into the can.
  • the insert comprises a vessel comprising a generally cylindrical hollow part 3, closed at its upper end and open at its lower end and having an internal split axial stem 4 having detents 5, 6 & 7.
  • a generally cylindrical plunger part 8 Slidably and sealingly engaged within the open end of the hollow part 3 is the upper end of a generally cylindrical plunger part 8, having an internal cavity 9 and together with the hollow part 3 forming the vessel.

  • the top of the plunger part 8 as far out as the outer surface of the inner wall component 11 is shown in Figure 3 and comprises a central hub 13 having a part conical aperture 14 and spokes 15 between which are 235 generally segmental apertures 16.

  • the straps 20 fold outwardly to retain the insert in position in the container. Because of the action of the detent 7 noted in the preceding paragraph, the straps still serve to retain the insert in position once the can has been opened.
  • the insert is broadly similar to that of Figure 1 to 5 and comprises a vessel comprising a generally cylindrical hollow part 103, closed at its upper end and open at its lower end and

  • the lower portion of the plunger part 108 differs from that of the plunger part 8 of the insert of Figures 1 to 5 in that there are no apertures and slots nor a ring of elastomeric material nor a recess for the ring to be displaced into. Also, near the upper end of the plunger

  • the insert comprises a vessel comprising a generally cylindrical hollow part 201, closed at its upper end and open at its lower end, and a generally cylindrical plunger part 202, having its upper end 355 slidably and sealingly engaged within the open end of the hollow part 201.
