Definitions
- This invention relates generally to self-cooling fluid containers and specifically to an internal self-cooling beverage container.
- HFCs hydrofluorocarbons
- a beverage container of conventional exterior dimensions, readily adaptable to existing packaging, stacking, transporting and handling needs.
- An upper chamber containing the beverage to be cooled is axially provided with a refrigerant chamber affixed to the base of the upper chamber and extending at least partially into the upper chamber.
- the interior region of the refrigerant chamber is fluidicly isolated from the interior region of the upper chamber.
- the pressurized refrigerant chamber contains an environmentally friendly refrigerant of a determined quantity in liquid form and is provided at its lower end by a sealed aperture integral with the base of the upper chamber.
- a third chamber serves several functions. Firstly, it provides a means for conveniently venting the refrigerant chamber by delivering a seal opening member to the sealed aperture. Secondly, it provides a venting chamber, or refrigerant dispersal assembly, wherein the volatile evaporating refrigerant is vented and decelerated, thus eliminating the risk of a blast of spray being directed at the consumer. Further, the third chamber increases refrigeration efficiency by maximizing the surface area of cooling to include not only the refrigerant chamber, but also the lower portion of the surface of the upper beverage container. This third unpressurized chamber may be formed as a separate generally cup-shaped cap in preferably threaded engagement to the base of the upper chamber.
- the inner surface of the base of the cap is further provided with a seal opening member (for example, a perforation member) spaced in alignment with the sealed aperture.
- a seal opening member for example, a perforation member
- Rotation of the cap in threaded engagement with the upper chamber results in an upward movement of the perforation member which perforates the seal of the aperture of the refrigeration chamber, thus venting and dispersing the evaporating refrigerant into the third chamber at atmospheric pressure.
- the ensuing cooling effect of evaporation and the adiabatic expansion of refrigerant vapor cools the walls of the refrigerant chamber and the base of the upper chamber, cooling the beverage by thermal conduction.
- the upward movement of the seal opening member may be facilitated by a bead-and-groove engagement between the cap and the exterior wall of the upper chamber.
- the base of the cap may be provided as to be sufficiently flexible to permit upward displacement of the seal opening member by upward manipulation of the cap base as a means of venting the refrigerant.
- FIG. 1 A perspective view which has been partially cut away of an embodiment of the invention.
- FIG. 2 A sectional view taken along line
- FIG. 1 2-2 of FIG. 1 illustrating the perforation of the sealing means of the embodiment shown in FIG. 1.
- FIG. 3. A sectional view of an alternative embodiment of the present invention prior to refrigerant dispersal.
- FIG. 4. A sectional view of the embodiment shown in FIG. 3. after refrigerant dispersal.
- FIG. 5 A sectional view of a third embodiment of the present invention.
- FIG. 6 An enlarged sectional plan view of the perforation member of any of the described embodiments after perforation of the seal of the refrigerant chamber.
- FIG.l shows a self-cooling container for carbonated soft drinks, beer and the like indicated at reference numeral 10.
- the container is shown having a conventional opening tab 15 on its upper end wall 11 and conforms generally to conventional exterior dimensions and shape of such containers.
- Each structural component of the invention is of a composition preferably selected from aluminum, steel, aluminum and steel or other metal or metal alloy, plastic or any other material of sufficient strength, heat conductivity and recyclability.
- the container 10 is divided into three generally cylindrical chambers: an upper chamber providing a fluid (typically a beverage) vessel 12; a lower chamber providing a refrigerant vapor dispersal vessel 21, and a refrigerant capsule 30 axially disposed within and concentric to the beverage vessel 12.
- the beverage vessel 12 of the upper chamber is defined by the walls of cylindrical side wall 16 and generally disc-like top wall 11 and base wall 13.
- the cylindrical side wall 16 has a reduced diameter portion 17 at its lowermost end.
- the base wall 13 of the beverage vessel is axially provided with an aperture 19.
- the dispersal vessel 21 of the lower chamber is defined by a separate generally cup-shaped cap 20 having preferably a generally concave base portion 27 and a cylindrical side wall 22.
- the sidewall 25L of the cap 20 fits radially around the annular reduced portion 17 of the upper chamber.
- An annular sealing member 99a about the upper open edge of the cap 20 is in slidable, rotatable, sealing engagement with the annular reduced portion 17 of the sidewall 16.
- the sidewall 22 of the cap is in additional engagement with the annular reduced portion 17 of the upper chamber 12 by way of vertical displacement members described in detail below.
- the refrigerant capsule 30 is fixed at its lower end by welding or the like, to the base wall 13 of the beverage vessel 12.
- the capsule includes an interior refrigerant region which contains a predetermined quantity of a refrigerant, under pressure and in liquid form, preferably selected from the group of HFC's developed by DuPont and others.
- the capsule 30 is axially provided at its lower end with an aperture 19a which aligns with the aperture 19 of the beverage vessel base 13.
- the apertures are sealed by a sealing element 32 - for example, a perforatable foil seal of sufficient strength to maintain the pressurized refrigerant within the closed region interior to the refrigerant capsule 30.
- the cavity, or fluid region, defined by the interior walls of the beverage vessel 12 and the exterior walls of the refrigerant capsule contains the beverage to be cooled and is accessible to the consumer via a conventional die-cut pull tab device (openable port) 15.
- the sealing element 32 thus forms a common wall (or coupling portion of the walls) between the refrigerant region and the dispersal region.
- a cooling activator which includes a seal opening member.
- the seal opening member is aligned vertically with the sealing element 32 (i.e., coupling portion) covering aperture 19, 19a.
- FIGS. 2-6 show the seal opening member as a perforation member 26, preferably an acute cone in shape with fluted grooves 26a vertically aligned about its circumference.
- a valve could be substituted for the perforable sealing element 32 and the perforation member 26.
- the cap 20 is moved upward relative to the beverage vessel 12 guided by the vertical displacement members
- the perforation member 26 is thus vertically displaced within the aligned apertures 19, 19a, perforating the sealing element 32, shown in FIG. 6.
- the refrigerant upon exposure to normal atmospheric pressure, rapidly evaporates and expands through the apertures 19, 19a into the vapor dispersal vessel 21, wherein the volatile vapor is decelerated.
- the refrigerant capsule 30 and the base wall 13 of the beverage vessel 12 become cooled by conduction as a result of the cooling effect of evaporation and the adiabatic expansion of the refrigerant vapor. This cooling is accordingly conducted to the beverage in vessel 12 which is subsequently cooled.
- the expanding and evaporating refrigerant is vented from the vapor dispersal vessel through the venting pores 29 indicated by the arrows 29a in FIGS. 2 and 4.
- the rate that the refrigerant vapor is vented regulates the efficiency of the cooling effect and is actuated by the size of apertures 19, 19a, the size of the vapor dispersal vessel 21 and the size of the venting pores 29.
- an arrangement of vertically aligned baffles may be affixed to the cap base 27 within the vapor dispersal cavity to further decelerate the rate of refrigerant vapor dispersal to maximize cooling efficiency.
- the aforesaid vertical displacement members guide the sliding vertical displacement of cap 20 about the annular portion 17 of the beverage vessel 12.
- thread members 23a are provided on the interior side wall 22 in threaded, rotatable engagement with the corresponding thread members 23b of the exterior wall of annular portion 17.
- vertical displacement of the perforation member 26 is achieved by rotation of the cap 20 about the beverage vessel 12.
- "bayonet"-type sliding engagement between the cap 20 and vessel 12 may be provided whereby a plurality of beads 24a fixed to interior side wall 22 are slidable with plurality of corresponding grooves 24b located on the exterior wall of annular portion 17.
- the device is activated by an upward manipulation of the cap 20 with the beads 24a guided vertically within grooves 24b.
- a horizontal portion of the grooves 24b is provided to allow for a rotational locking step to prevent accidental discharge occurring (for example, owing to rough handling).
- the cap portion 20 may be a separate unit, with the beverage vessel 12 being vended separately.
- the cap 20 may be integral of the vending machine, for example, and provide a sealed vapor dispersal cavity and perforation member 26 for multiple use in association with each separately vended beverage vessel, in the same manner as described above.
- the cap 20 is integral of the side walls 16 of beverage vessel 12. Upward displacement of the perforation member 26 as to perforate the refrigerant capsule sealing member 22 is achieved by an upward flexing of the base portion 27 of the vapor dispersal vessel 21.
- the base portion 27, shown in FIG. 5, is designed to be sufficiently deformable in its centre portion 27a to achieve such a displacement, yet sufficiently rigid in its annular outer portion 27b to support the weight of the container 10 with minimal deformation.
