Definitions

  • the present invention relates to containers.
  • US-A-4,656,838 describes a container for a beverage having a tubular peripheral wall defining two spaced open ends, one open end being closed by a top member, and the other open end being closed by a base member, said peripheral wall and the top and base members defining an internal cavity for containing a beverage, wherein said base member is indented to define an external cavity which extends within said peripheral wall substantially along the longitudinal axis of said container, and wherein said external cavity extends within the internal cavity, but is separated therefrom by said base member.
  • the container in this US specification is operable to cool or refrigerate the beverage in the can.
  • a container as defined above is characterised in that said external cavity retains insert means arranged to keep the contents within the internal cavity warm or cold.
  • the external cavity may be provided in any conventional container without affecting the external configuration or size of the container, although it does reduce the capacity thereof. This means that a container of an embodiment of the invention can be filled on existing filling lines without difficulty. Furthermore, because of its longitudinal extent, the external cavity provides a large surface area in contact with the contents of the container for heat transfer.
  • the insert may be selected from a plurality of different inserts such that the container may be arranged to be cool retaining, or heat retaining, at the choice of the manufacturer, retailer or user.
  • the base member is formed from sheet material, preferably of a conductive material.
  • the sheet material of the base member is generally metal, preferably aluminium.
  • the sheet material of the base member is shaped to form a peripheral defining wall of said external cavity. It will be appreciated that one surface of said peripheral defining wall will be within the external cavity, and that the opposed surface of the peripheral defining wall will be within the internal cavity.
  • At least said opposed surface of said peripheral defining wall has means to extend its surface area.
  • Such surface area extending means may be, for example, vanes or other configurations provided on said opposed surface.
  • the use of an extended surface area aids in heat transfer.
  • the container, and its external cavity may be of any appropriate shape, configuration and size.
  • the tubular peripheral wall is substantially cylindrical defining, for example, a generally cylindrical container or can.
  • the external cavity is substantially cylindrical with a domed, closed end.
  • the container may be made by any appropriate means.
  • the container may be manufactured in two parts.
  • the container will be manufactured in three parts, namely, the shaped base member, the peripheral wall, and the top member.
  • the container may be of any appropriate material, for example, of plastics material. However, as it is generally required that the peripheral defining wall of the external cavity be of metal or other conductive material, it is presently preferred that the rest of the container be made of the same material.
  • the metal of the container may be, for example, aluminium.
  • the outer surface of the peripheral wall may be insulated in any required manner.
  • an outer wrapper of a plastics material may be provided on the exterior of the peripheral wall.
  • the peripheral wall, at least, of the container may be made of a plastics material sufficiently thick to provide for heat insulation.
  • the insert means may be an elongate insert provided with a peripheral wall.
  • the insert means does not have a peripheral wall and insert material is directly retained within the external cavity.
  • One or more insert means may be provided for retention within the external cavity of the container.
  • the insert means is an elongate insert which is arranged to be retained by a push fit within the external cavity. Not only does this simplify the retention of the insert, but is also ensures good heat conducting contact between the insert and between the peripheral defining wall of the external cavity.
  • each insert is shaped to have an external configuration which is substantially the same as the internal configuration of the external cavity.
  • each insert may be substantially cylindrical with a domed top and a planar base.
  • the insert may be arranged to keep the contents of a container cool.
  • the insert may comprise a freezable material. This material is preferably one which melts at less than 5°C, for example, water, heavy water or a freezable gel. It will be appreciated that if a frozen insert is inserted into the external cavity of a cooled container, the insert will act to absorb heat from the contents of the container, such heat tending to melt the frozen material of the insert. Such a frozen insert may be effective in keeping the container contents chilled for up to 8 hours.
  • a bottom cap is provided to extend across the base of the external cavity when the insert means is retained therein. Such a cap may act to deny accidental access to the insert means.
  • the present invention relates to a container, such as a can, for beverages which is provided with means to keep the contents warm or cold.
  • a container such as a can
  • beverages which is provided with means to keep the contents warm or cold.
  • beverages such as beer, soft drinks and iced tea cool.
  • drinks such as tea, coffee, hot chocolate and soup warm.
  • a container of the present invention can achieve these functions by choice of an appropriate insert.
  • Embodiments of the beverage containers described herein may also be used to have a self-cooling or self-heating function. However, such embodiments are not within the scope of this application.
  • Figure 1 shows a cross section through a beverage container 10.
  • This container 10 has a substantially cylindrical peripheral wall 12 which is closed at one open end by a top member 14.
  • a conventional container as 10 would also have a generally planar base closing the other open end of the peripheral wall 12.
  • the container 10 of the invention has a base member 16 formed from sheet material to define an elongate, external cavity 20 which extends within the peripheral wall 12 substantially along the longitudinal axis A-A of the container 10. It will be appreciated that the peripheral wall 12 and the top and base members 14 and 16 of the container together define an internal cavity 22 in which the beverage is received. It will be seen that the external cavity 20 extends within this internal cavity 22, but is separated therefrom by the peripheral defining wall 17 of the external cavity 20 which is formed by the base member 16.
  • the container 10 illustrated in Figure 1 is configured to have the same external dimensions and shape as a conventional half litre beer can. However, the presence of the external cavity 20 reduces its capacity.
  • the arrangement shown in Figure 1 reduces the capacity of a half litre can to 33 litre.
  • Figure 2 illustrates an alternative configuration which reduces the capacity of a half litre can to .44 litre.
  • each of the cans of Figures 1 and 2 has the same external dimensions as conventional cans, and therefore each can be used and filled on existing filling lines.
  • the external cavity 20 of the can 10 is to be utilised to enclose an insert to effect heating or cooling of the can, or to keep the contents thereof warm or cool.
  • the external cavity 20 extends over a major part of the length of the longitudinal axis A-A of the can 10. This provides the peripheral defining wall 17 of the external cavity 20 with a large surface area within the can 10 to enhance heat conduction. If necessary, vanes or other surface area extending devices may be carried on the surface of the peripheral defining wall 17 which is within the internal cavity 22. Such surface extending means (not shown) enhance heat conduction between the internal and external cavities 20, 22 without interfering with the filling of the container on a conventional filling line.
  • a can 10, as show in Figure 1 may be used with a selected insert to obtain the effect required.
  • the insert may be mounted in the can after it has been filled and sealed. This means that any treatments required on the can and its contents may be made without any adverse effects on the insert.
  • a filled can 10, as shown in Figure 1 may be subjected to a pasteurisation process if required.
  • Figures 2 to 4 show an embodiment of a can 10 to be used to keep cold drinks cold.
  • the can 10 shown in Figure 2 is substantially identical to that of Figure 1 except that the external cavity 20 is somewhat narrower.
  • the can 10 of Figure 2 has been covered with an insulating material sleeve 24, and a top cap 26 and a bottom cap 28 of an insulating material are provided.
  • Figure 3 shows an insert 30 which can be inserted into the external cavity 20 of the can 10 as shown in Figure 2.
  • the insert 30 is configured to be a push fit within the cavity 20 such that specific retention means will not generally be required.
  • the external periphery of the insert 30 is substantially the same size and shape as the internal periphery of the external cavity 20 to ensure good heat conduction.
  • the bottom insulating cap 28 co-operates with the can 10 and the insert 30 and may have a function of aiding the retention of the insert 30.
  • the bottom insulating cap 28 is provided simply to keep the contents of the can cold and/or to act as a tamper proof seal.
  • the insert 30 of Figure 3 is a metal cylinder, for example, filled with a material 31 which melts at a temperature of less than 5°C.
  • the material 31 within the insert 30 may be water, heavy water, or a gel with a low melting temperature.
  • the can as shown in Figures 2 to 4 may be assembled by the user or by a retailer.
  • the can 10 with its contents, but without its insert 30, is stored in a refrigerator, and the insert 30 is kept in a freezer until the material 31 therein is frozen solid.
  • the insert 30 is removed from the refrigerator and the frozen insert 30 is inserted in its cavity 20.
  • the insulating cap 28 is put in place.
  • the contents of the can will keep cool for up to 8 hours. This means that the can 10 can be transported, or left without refrigeration, for this time and a chilled drink will still be available from it.
  • the defining wall 17 be of metal and that the wall of the insert 30 similarly be of metal. It may also be desirable to interpose a conductive gel between the insert 30 and the defining wall 17.
  • the insert 30 be contained by a peripheral wall although it is preferable. It would, for example, be possible to pack ice cubes with cold water into the external cavity 20. Of course, in this case a water tight seal would be required for the base of the external cavity 20.
  • Any insert material which has a low melting temperature and can absorb heat over an extended period may be used in place of the frozen water, frozen heavy water, or frozen gel to provide an insert 30 to keep the contents cold.
  • a warmed can 10 it is equally possible to keep the contents of a warmed can 10 warm by use of a heated insert.
  • an insert, as 30, filled with a heat retaining gel may be heated and then inserted into the external cavity 20 to keep the heated contents of the can warm.
  • Figure 5 shows an insert 40 arranged to cool or chill the contents of a can 10.
  • the insert 40 is a cylinder having a gas chamber 48 containing carbon dioxide under pressure.
  • the gas is pressurised to the extent that it is liquid.
  • a valve (not shown) is provided to control an opening 42 of the gas chamber 48. When the valve is opened, the gas vents, and as it does so it evaporates and absorbs heat.
  • carbon dioxide may be vented directly to atmosphere the insert 40 shown in Figure 5 includes an expansion chamber 44 in which the vented gas may expand. In this manner, the flow rate of the gas as it exits through a port defined in a base structure 46 is reduced for safety.
  • the relative sizes of the gas chamber 48 and of the expansion chamber 44 may be chosen as required.
  • the gas within the gas chamber 48 may be any gas which would be subjected to a change of phase at appropriate temperatures. Some gases may have to be flowed through a catalyst or chemicals before they are vented to atmosphere and such catalysts or chemicals may be provided within the chamber 44.
  • the self-cooling can incorporating an insert as 40 is preferably manufactured with the insert in place.
  • the base structure 46 of the insert, which supports the vent valve, is received within an appropriate recess in the base member 16.
  • a bottom cap, as 28, is preferably retained on the can to hide the base structure 46 from view and prevent accidental actuation. Preferably, destruction of the bottom cap 28 is required to give access to the base structure 46.
  • the bottom cap 28 therefore provides an indication of tampering.
  • an insert capable of absorbing heat is inserted in the external cavity of the can.
  • Any appropriate insert may be used.
  • an electrically powered insert such as one utilizing the Peltier effect, may be provided.
  • An electrically powered insert may include appropriate batteries or the insert may be connected to mains or external battery power.
  • Figure 6 shows an insert 50 for heating the contents of a can 10.
  • the illustrated insert 50 uses water and lime to provide an exothermic chemical reaction but any other constituents generating heat may be utilised.
  • the insert 50 shown in Figure 6 comprises a generally cylindrical metal cylinder which has a plurality of spaced, longitudinally extending channels 52 along its outer surface. Thus, when the insert 50 is within the external cavity 20, the channels 52 extend between the insert 50 and the wall 17 of the cavity 20. Internally the length of the cylinder 50 is divided by a membrane 54 into two chambers 56, 58. The first of these chambers 56 contains lime, and the second of these chambers 58 contains water. Within the water chamber 58 there is also a membrane piercer 60 which is actuatable by a button 62 provided at the bottom of the insert 50. A tamper evident seal 64 may also be provided.
  • the insert 50 is received within the external cavity 20 of a container 10 so that the button 62 is at the base of the can.
  • the base wall 16 of the can is shaped to provide a domed base and it is within this dome that the button 62 can be accommodated.
  • the can 10 In its normal state, the can 10 will have a base cap, as 28, which protects the button 62.
  • the can When it is required to heat the contents of the can, the can is stood on its top so that its base is accessible. Any base cap 28 is removed so that the button 62 is accessible. Depression of the button 62 causes the membrane 54 to be pierced by the membrane piercer 60 and hence water from the chamber 58 flows over the lime in chamber 56 causing the exothermic reaction.
  • the steam which is generated exits through a membrane covered vent 66 provided on the top dome of the insert 50 and the steam is discharged from the container by way of the channels 52.
  • the user will retain the can on its top until the exit of the steam has been completed.
  • the contents of the can will have been heated to a satisfactory temperature. For example, it can take less than two minutes to heat the contents of the can to 70°C. At this juncture, the can is turned the correct way up, and the contents of the can can be dispensed in the normal way.
  • an insert capable of generating heat is inserted into the external cavity of the can.
  • Any appropriate insert may be used.
  • any appropriate chemical reaction may be utilised to provide the heating.
  • the heating may be electrically powered, and the insert may include batteries or be connected to mains or external battery power.
