Description
- This application is a nonprovisional and claims benefit of U.S. Patent Application Ser. No. 61/166,136, filed Apr. 2, 2009, the disclosure of which is incorporated herein by reference.
- The invention relates generally to the field of cans and can manufacturing. More specifically, the invention relates to the field of self-chilling cans and methods of their manufacture.
- A self-chilling beverage can according to one embodiment includes an outer compartment, a pull tab, an inner compartment, and a puncturing member. The outer compartment has at least one sidewall, a top end, and a bottom end. The sidewall, the top end, and the bottom end of the outer compartment collectively form a first cavity for storing a liquid. The top end of the outer compartment has a rupturable tear panel which may be ruptured to provide access to the liquid stored within the first cavity. The pull tab has a front end and a back end. The back end of the pull tab is placed adjacent to the rupturable tear panel, such that when the front end of the pull tab is pulled away from the top end of the outer compartment, the rupturable tear panel ruptures and moves into the first cavity. The rupturing of the rupturable tear panel provides access to the liquid in the first cavity. The inner compartment has at least one sidewall, a top end, and a bottom end. The inner compartment is located inside the first cavity, and has second and third cavities that are separated by a rupturable membrane. The puncturing member is underneath the rupturable tear panel. The puncturing member extends into the first cavity and the second cavity and rests above the rupturable membrane. When the front end of the pull tab is pulled to provide access to the first cavity, the rupturable tear panel pushes the puncturing member down towards the rupturable membrane of the inner compartment, eventually puncturing the rupturable membrane and allowing substances present in the second and third cavities to mix.
- According to another embodiment, a self-chilling beverage can includes an outer compartment having at least one sidewall, a top end and a bottom end such that a cavity is formed to retain a liquid. The self-chilling beverage can also includes an inner compartment that has at least one sidewall, a top end and a bottom end. A rupturable membrane separates the inner compartment into a first chamber and a second chamber. One of the first and second chambers generally comprises water, while the other chamber generally comprises a coolant. The coolant is selected such that an endothermic reaction occurs when the coolant comes into contact with the water. Means for puncturing the rupturable membrane are provided such that a user can puncture the rupturable membrane and access the liquid in the cavity with a single motion.
- According to still another embodiment, a self-chilling beverage can includes an outer compartment with at least one sidewall, a top end and a bottom end such that a cavity is formed for retaining a liquid. The self-chilling beverage can also includes an inner compartment with at least one sidewall, a top end and a bottom end collectively forming a second cavity to retain a substance. The substance can either be water or a coolant. The coolant is selected such that an endothermic reaction occurs when the coolant comes into contact with the water. A balloon is affixed to the bottom end of the inner compartment. The balloon may comprise either water or the coolant. The water or the coolant retained within the balloon is separated from the substance in the second cavity. Means for puncturing the balloon are provided such that a user can puncture the balloon and access the liquid in the first cavity by a single motion.
- According to still yet another embodiment, a self-chilling beverage can includes an outer compartment that has at least one sidewall, a top end and a bottom end such that a first cavity is formed for retaining a liquid. The top end has a rupturable tear panel to provide access to the liquid stored within the first cavity. The top end of the outer compartment has a pull tab that has a front end and a back end. The back end of the pull tab is placed adjacent to the rupturable tear panel. When the front end of the pull tab is pulled away from the top end, the rupturable tear panel ruptures and moves into the first cavity. The rupturing of the rupturable tear panel opens the first cavity and provides access to the liquid. The self-chilling beverage can also includes an inner compartment that is placed within the first cavity. The inner compartment has at least one sidewall, a top end and a bottom end that collectively form a second cavity. Means for dividing the second cavity into two areas are provided, such that two different substances can be separately stored within the two areas. The two substances are selected such that an endothermic reaction occurs when the two substances are allowed to come into contact with each other. A puncturing member extends into the first cavity and one of the two areas, and lies underneath the rupturable tear panel. When the front of the pull tab is pulled to provide access to the first cavity, the rupturable tear panel pushes the puncturing member down towards the other area. As the puncturing member moves downwards, it ruptures the means for dividing the second cavity and allows the two substances to come into contact with each other.
- The self-chilling beverage can disclosed herein provides several benefits, some of which are detailed below. For example, the self-chilling beverage can may reduce the cost borne by retailers of beverage cans to store and market the beverage cans at low temperatures. Generally, retail stores utilize electric refrigerators to keep the beverage cans chilled. The self-chilling beverage can may eliminate or greatly reduce the need for retailers to employ electric refrigerators to chill the beverage cans. Therefore, the retailers will save some of the costs associated with purchasing separate refrigeration equipment to store the beverage cans at low temperatures, as well as the costs related to maintaining the separate refrigeration equipment. Moreover, reduction of in-store refrigeration equipment will result in lower electricity bills for the retailers. The self-chilling beverage can may similarly reduce or eliminate the need for vending machines that employ traditional refrigeration methods to store the beverage cans at low temperatures.
- Notably, as the self-chilling beverage can does not use electricity or refrigerant gas to chill the beverage within the can, the self-chilling beverage can does not adversely impact the environment. Also, the reactants employed to, cause the endothermic reaction within the self-chilling beverage can may be non-toxic, such that even if these reactants accidentally mix with the beverage, the accidental mixing does not render the beverage unsafe for human consumption.
- The beverage within the self-chilling beverage can may be chilled in a significantly shorter amount of time as compared to customary refrigeration methods. When the beverage cans are placed in freezers to chill the beverage cans at a faster rate, the beverage cans often explode upon the freezing and expansion of the contents within the beverage cans. The self-chilling beverage can, on the other hand, is not prone to exploding.

FIG. 5 is a cross-section view similar to that inFIG. 3 , but depicting an alternate embodiment having a rupturable balloon placed at the bottom of the inner compartment. - Detailed descriptions of various embodiments are set forth herein to enable those skilled in the art to practice the current invention.
FIGS. 1 through 4 show a self-chilling beverage can 8. As set forth, for example, inFIG. 1 , anouter compartment 10 has atop end 12, abottom end 14, and at least onesidewall 16. Thetop end 12, thebottom end 14 and thesidewall 16 collectively form afirst cavity 18. A liquid 20 can be stored within thefirst cavity 18. The liquid 20 may be a carbonated or non-carbonated beverage, such as a soft drink, beer, fruit punch, juice, or any other liquid that is intended to be chilled (including liquids that cannot be consumed). At the outset, thefirst cavity 18 is water-tight, sealed by thetop end 12, thebottom end 14, and thesidewall 16 such that any liquid 20 stored within thefirst cavity 18 cannot escape out of thefirst cavity 18. - A
pull tab 22 is coupled to thetop end 12. Thepull tab 22 may be coupled to thetop end 12 by arivet 28 or any other appropriate fastener. Thepull tab 22 has afront end 24 and aback end 26. Generally, thepull tab 22 is coupled to thetop end 12 at, or close to, theback end 26 of thepull tab 22, with thefront end 24 of thepull tab 22 resting above thetop end 12 such that thefront end 24 of thepull tab 22 can easily be pulled away from thetop end 12. When thefront end 24 of thepull tab 22 is pulled away from thetop end 12, thepull tab 22 may remain coupled to thetop end 12 and theback end 26 of thepull tab 22 is pushed downward towards thetop end 12. - The
top end 12 includes arupturable tear panel 30 that has aproximal end 32 and adistal end 34. Therupturable tear panel 30 is constructed such that when a downward force is applied to theproximal end 32 of therupturable tear panel 30, at least a portion of the tear panel 30 (e.g., the distal end 34) disconnects from thetop end 12 and moves into thecavity 18 while theproximal end 32 remains connected to thetop end 12. - In use, then, the
pull tab 22 is utilized to cause thedistal end 34 of therupturable tear panel 30 to disconnect from thetop end 12. More specifically, theback end 26 of thepull tab 22 is placed adjacent to theproximal end 32 of therupturable tear panel 30. When thefront end 24 of thepull tab 22 is pulled away from thetop end 12, theback end 26 of thepull tab 22 pushes theproximal end 32 of therupturable tear panel 30 downward, causing thedistal end 34 of therupturable tear panel 30 to disconnect from thetop end 12 and move downward into thecavity 18. - The
outer compartment 10 detailed thus far can be constructed according to can manufacturing processes known in the art. Theouter compartment 10 may be made of aluminum, steel, metal alloy, and/or any other appropriate materials. - Turning to
FIG. 2 , thecan 8 further includes aninner compartment 40. Theinner compartment 40 has atop end 42, abottom end 44, and at least onesidewall 46. The ends 42, 44 of theinner compartment 40 have a smaller diameter than theends outer compartment 10. Similarly, the length of the inner compartment sidewall 46 (i.e. the distance between the top and bottom ends 42 and 44 of the inner compartment) is shorter than the length of theouter compartment sidewall 16. By virtue of the smaller dimensions of theinner compartment 40 as compared to theouter compartment 10, theinner compartment 40 can be placed within theouter compartment 10. As will be apparent to those skilled in the art, theinner compartment 40 may be constructed out of the same or different materials than theouter compartment 10. - The
top end 42 of theinner compartment 40 may be coupled to thetop end 12 of theouter compartment 10 by one ormore spacing members 48. In some embodiments, the spacingmember 48 is of a rigid construction such that the spacing between the sidewalls and ends of the inner andouter compartments member 48 may be a rivet or any other appropriate spacer. - A puncturing
member 60 has atop end 62 and extends upwards from thetop end 42 of theinner compartment 40 towards thetop end 12 of theouter compartment 10. Thetop end 62 of the puncturingmember 60 rests beneath the rupturable tear panel 30 (e.g., beneath the distal end 34). In some embodiments, thetop end 62 of the puncturingmember 60 may be coupled to thedistal end 34 of therupturable tear panel 30, for example by a rivet or by welding thetop end 62 of the puncturingmember 60 to thedistal end 34 of therupturable tear panel 30, although such coupling is not required. - As shown in
FIG. 3 , arupturable membrane 74 is coupled to thesidewall 46 of theinner compartment 40 and divides an area formed by thesidewall 46 and the top and bottom ends 42 and 44 into asecond cavity 70 and athird cavity 72. Thesecond cavity 70 and the third cavity 72 (and indeed theouter compartment 10 and the inner compartment 40) can be of different sizes, as will be appreciated by those skilled in the art. Therupturable membrane 74 is made out of a material that can be punctured by the puncturingmember 60. For example, therupturable membrane 74 may be made out of rubber, latex, polychloroprene, etc. Though not specifically shown, therupturable membrane 74 may be coupled to a wall or protrusion that extends into theinner compartment 40, instead of (or in addition to) being coupled directly to thesidewall 46. - The
rupturable membrane 74 prevents the contents of thesecond cavity 70 and thethird cavity 72 from mixing, so two different substances may be retained in thesecond cavity 70 and thethird cavity 72. These substances may include, for example, ammonium nitrate, sodium carboxyl methyl cellulose, sodium chloride, hydrated sodium acetate, potassium chloride, potassium nitrate, ammonium chloride, water, urea, guar gum, and mixtures of these substances. The substance stored in thesecond cavity 70 may be a coolant such that if the coolant comes into contact with the substance stored in thethird cavity 72, an endothermic reaction occurs. Or, the coolant may be stored in thethird cavity 72, such that an endothermic reaction occurs when the coolant comes into contact with the substance in thesecond cavity 70. For example, water may be stored in one of the second orthird cavities other cavity third cavities other cavity third cavities other cavity cavities - A puncturing
member housing 66 is coupled (e.g., adhered) to thetop end 42 of theinner compartment 40 and may extend into thesecond cavity 70, and the puncturingmember 60 rests within the puncturingmember housing 66. The puncturingmember housing 66 allows the puncturingmember 60 to move vertically downward towards thethird cavity 72 but generally restricts the movement of the puncturingmember 60 from side to side. Accordingly, the puncturingmember 60 is not coupled to the puncturingmember housing 66, or is at least movable relative to the puncturingmember housing 66. The puncturingmember 60 has abottom end 64 that rests above therupturable membrane 74. Thus, the puncturingmember 60, with itstop end 62 outside thesecond cavity 70, extends through thetop end 42 of theinner compartment 40 into thesecond cavity 70 and rests above therupturable membrane 74. - The
inner compartment 40 is constructed such that it is water-tight, sealed by theends sidewall 46 so the substances in the second orthird cavities first cavity 18. The water-tight nature of theinner compartment 40 is maintained, notwithstanding themovable puncturing member 60 which extends upward from within thesecond cavity 70 through thetop end 42 of theinner compartment 40 towards thetop end 12 of theouter compartment 10. In some embodiments, a seal is used with the puncturingmember 60 to ensure that theinner compartment 40 remains water-tight. - An
insulation layer 80 may be coupled to theouter compartment 10. Theinsulation layer 80 insulates the liquid 20 within thecavity 18 from heat and may surround the entireouter compartment 10 or only a part thereof, such as thesidewall 16. In one embodiment, theinsulation layer 80 is coupled to the inside of thesidewall 16 such that it comes into contact with the liquid 20 retained in thecavity 18. In this embodiment, particularly if the liquid 20 is intended for consumption, theinsulation layer 80 may be made out of a non-toxic material such that theinsulation layer 80 does not render the liquid 20 unsafe for human consumption. -
FIG. 4 shows a cross-section through the self-chilling beverage can 8 with thefront end 24 of thepull tab 22 pulled away from thetop end 12 of theouter compartment 10. When thefront end 24 of thepull tab 22 is pulled away from thetop end 12 of theouter compartment 10, theback end 26 of thepull tab 22 is pushed downward towards thetop end 12 of theouter compartment 10. By virtue of the placement of theback end 26 of thepull tab 22 adjacent to theproximal end 32 of therupturable tear panel 30, theback end 26 of thepull tab 22 pushes theproximal end 32 of therupturable tear panel 30 down towards thetop end 12 of theouter compartment 10. This causes thedistal end 34 of therupturable tear panel 30 to disconnect from thetop end 12 of theouter compartment 10 and move into thecavity 18. Anopening 90 is formed when thedistal end 34 of therupturable tear panel 30 disconnects from thetop end 12, and the liquid 20 can be accessed through thisopening 90. - As the
distal end 34 of therupturable tear panel 30 moves into thecavity 18, thedistal end 34 comes into contact with thetop end 62 of the puncturingmember 60. Thedistal end 34 of therupturable tear panel 30 then pushes thetop end 62 of the puncturingmember 60 down towards thetop end 42 of theinner compartment 40. This downward movement of the puncturingmember 60 causes thebottom end 64 of the puncturingmember 60 to push against and puncture therupturable membrane 74. The puncturing of therupturable membrane 74 eliminates the barrier between the substances in thesecond cavity 70 and thethird cavity 72, allowing the substances in these twocavities cavities cavity 18, thereby reducing the temperature of the liquid 20. The liquid 20, thus, may now be at a lower temperature than it was before the endothermic reaction. Although it is not necessary to shake the self-chilling beverage can 8, shaking of thecan 8 may enable the endothermic reaction to transpire at a faster rate. The chilledliquid 20 can be accessed through theopening 90. -
FIG. 5 shows a cross-section of an alternate embodiment of a self-chilling beverage can 8′. The self-chilling beverage can 8′ includes anouter compartment 10′. Theouter compartment 10′ has at least onesidewall 16′, atop end 12′ and abottom end 14′, which collectively form afirst cavity 18′. A liquid 20′ is stored in thefirst cavity 18′. The self-chilling beverage can 8′ also includes aninner compartment 40′ which has atop end 42′, abottom end 44′ and at least onesidewall 46′, which collectively form asecond cavity 102. Thealternate embodiment 8′ shown inFIG. 5 may be generally similar to the embodiments disclosed previously, except that theinner compartment 40′ of the self-chilling beverage can 8′ does not include arupturable membrane 74. Instead, a balloon or a bladder shapedcontainer 100 is placed at thebottom end 44′ of theinner compartment 40′ which allows two different substances to be stored within theinner compartment 40′. Theballoon 100 is made out of a material that can be ruptured by a puncturingmember 60′, such as rubber, latex, polychloroprene, etc. Theballoon 100 may be affixed to thebottom end 44′ of theinner compartment 40′ by glue, or theballoon 100 may be otherwise restrained so that theballoon 100 does not accidentally come into contact with the puncturingmember 60′. - A
first substance 110 is stored in theballoon 100, and asecond substance 112 is retained in thesecond cavity 102 of theinner compartment 40′; thesecond substance 112 does not initially come into contact with thefirst substance 110. As discussed previously, the first andsecond substances other substance pull tab 22′ away from thetop end 12′ of theouter compartment 10′ causes the punchingmember 60′ to move downward towards theballoon 100, eventually rupturing theballoon 100. The rupturing of theballoon 100 may allow thefirst substance 110 and thesecond substance 112 to mix, which in turn may cause an endothermic reaction. The endothermic reaction pulls in heat from the liquid 20′, thereby reducing the temperature of the liquid 20′. - Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present invention. Embodiments of the present invention have been described with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention.
- It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the claims. Not all steps listed in the various figures need be carried out in the specific order described.
