Self-carbonating beverage container

Abstract

A self-carbonating beverage container includes a beverage can housing adapted to hold a fixed portion of liquid. A carbonating gas bottle containing carbonating gas stored under pressure has a breakable seal through which the carbonating gas is released. The carbonating gas bottle is attached to the can. A spout is attached to the can such that one end of the spout is introduced into the beverage can housing and the other end of the spout has a puncturing mechanism facing the breakable seal of the carbonating gas bottle. Actuating the puncturing mechanism enables the carbonating gas to flow into the beverage can housing.

Claims

1. A self-carbonating beverage can, comprising: a) a beverage can housing adapted to hold a fixed portion of liquid, wherein the beverage can housing includes a side wall portion having a central axis, a can base attached to a bottom of the side wall and a can top having a can top lower part detachably connected to a top of the side wall and a can top upper part arranged to be rotatable relative to the can top lower part; b) a carbonating gas bottle containing carbonating gas stored under pressure having a breakable seal through which said carbonating gas is releasable, wherein said carbonating gas bottle is attached to said can top upper part by a fastener; and c) a spout attached to the can top lower part by a fastener such when the can top lower part is attached to the top of the side wall portion, one end of said spout extends into the beverage can housing and the spout other end comprises a puncturing means fastened firmly to the can top lower part; wherein when the can top is attached to the beverage can housing in an upright position, the puncturing means is positioned outside the central axis and the carbonating gas bottle is fixed in a horizontal position completely outside the central axis with the breakable seal facing toward the puncturing means in a horizontal direction such that, when the can top upper part is rotated relative to the can top lower part, the puncturing means engages the breakable seal of the carbonating gas bottle in the horizontal direction outside the central axis.

2. The self-carbonating beverage container according to claim 1, wherein the can top upper part is sufficiently rotatable relative to the can top lower part to cause the puncturing means to puncture the breakable seal to enable the carbonating gas to flow into the beverage can housing.

3. The self-carbonating beverage container according to claim 1, wherein the carbonating gas is carbon dioxide.

4. The self-carbonating beverage container according to claim 1, further including a press-button which can be actuated for causing the puncturing means to apply pressure on the breakable seal.

DETAILED DESCRIPTION OF THE INVENTION

(6) Throughout this description the term “beverage can” is used to indicate an essentially vertical container adapted to hold a fixed portion of liquid such as soft drinks, alcoholic beverages, fruit juices, energy drinks, etc. This term does not imply any particular shape, construction material (e.g., aluminum or tin-plated steel) or geometry, and invention is applicable to all suitable liquid containers.

(7) Reference will now be made to several embodiments of the present invention, examples of which are illustrated in the accompanying figures. Wherever practicable similar or like reference numbers may be used in the figures and may indicate similar or like functionality. The figures depict embodiments of the present invention for purposes of illustration only. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the invention described herein.

(8) FIG. 1 schematically illustrates an exploded-view of a self-carbonating beverage can 10, according to an embodiment of the invention. Beverage can 10 comprises a detachable can top having an upper part 6 and a lower part 5, a housing 1 defining a filling cavity filled with a liquid substance, a carbonating gas bottle 4 that may store pressurized carbon dioxide, and a spout 3.

(9) This exploded-view may also refer to the beverage can 10 in a disassembled state where the detachable can top is separated from the can housing 1 and the upper part 6 and the lower part 5 of the detachable can top are separated from each other. Carbonating gas bottle 4, containing carbonating gas stored under pressure, having a bottle top with a breakable seal through which the carbonating gas is released into the liquid beverage, is attached to the can top upper part 6 by a fastener such that the breakable seal is facing in a horizontal manner. Spout 3 is attached to the can top lower part 5 by a fastener such that one end of spout 3 is introduced into the beverage can housing 1 and the spout other end comprises a puncturing means 2 and is fastened firmly to the can top lower part 5 such that the puncturing means 2 is facing the breakable seal. According to this embodiment, the detachable can top upper part 6 and lower part 5 comprises engagement means which can engage the upper part 6 and lower part 5 by rotational movement such that the rotational movement further puncture the breakable seal while engaging the carbonating gas bottle 4 with the spout end facing the seal to enable the carbonating gas to flow into the beverage can housing 1. According to other embodiments of the present invention, the breakable seal can be opened or punctured by other suitable techniques or puncturing means. For example, by using a mechanism adapted to open the breakable seal by applying pressure on the seal, such as a pressing button or similar mechanism that can be operated to apply pressure on the seal.

(10) FIG. 2 is a simplified side view pictorial illustration of the self-carbonating beverage can 10 in an open position where the detachable can top is separated from the can housing 1 and the upper part 6 and the lower part 5 of the detachable can top are engaged, constructed and operative in accordance with an embodiment of the present invention.

(11) The basic combination of the engagement means which can engage the upper part 6 and the lower part 5 of the self-carbonating beverage can 10 by rotational movement is disclosed in FIG. 3. The abovementioned rotational movement further punctures the breakable seal of carbonated gas bottle 4 while engaging the carbonating gas bottle 4 with the end of spout 3 facing the seal to enable the carbonating gas to flow into the housing 1 of beverage can 10.

(12) Reference is now made to FIG. 4 which is a simplified side view pictorial illustration of the self-carbonating beverage can 10 in a closed position where the detachable can top is attached to the can housing 1 and the upper part 6 and the lower part 5 of the detachable can top are attached to each other such that the end of spout 3 facing the seal of the carbonating gas bottle 4 punctures the breakable seal while engaging the carbonating gas bottle 4 with the end of spout 3 facing the seal to enable the carbonating gas to flow into the housing 1 of beverage can 10, constructed and operative in accordance with an embodiment of the present invention.

(13) Although embodiments of the present invention have been described by way of illustration, it will be understood that the invention may be carried out with many variations, modifications, and adaptations, without departing from the scope of the claims.

(14) The embodiments described above are to be considered in all aspects as illustrative only and not restrictive in any manner. Thus, other system architectures, platforms, and implementations that can support various aspects of the invention may be utilized without departing from the essential characteristics as described herein. These and various other adaptations and combination of features of the embodiments disclosed are within the scope of the invention. The invention is defined by the claims and their full scope of equivalents.
