In another embodiment, air shaft 130 is operatively connected to each of fan 120 and bubble forming substrate 135. Air shaft 130 is configured to guide air moved by fan 120 to the vicinity of bubble forming substrate 135. Air shaft 130 may include a channel and/or a tunnel configured to contain the stream of air from fan 120. In one embodiment, air shaft 130 may be eliminated and fan 120 may be placed in appropriate proximity to bubble forming substrate 135 such that bubbles may be formed on bubble forming substrate 135. Air shaft 130 may be formed of any material, including without limitation, a polymer, a metal, an alloy, a composite, paper, or cardboard.
Bubble forming substrate 135 may be configured to receive a stream of air generated by fan 120 and/or transported by air shaft 130. Bubble forming substrate may have any of a variety of shapes, for example, a ring. Bubble forming substrate 135 may comprise a hollow portion and ports configured to evenly distribute a bubble solution transported by tube 140. In one embodiment, bubble forming substrate 135 is in the shape of a ring and includes a plurality of teeth formed along its interior surface, wherein the plurality of teeth are configured to at least substantially retain a bubble solution. In one embodiment, bubble forming substrate 135 is a ring and is configured such that the air stream generated by fan 120 crosses through the interior of the ring and at least substantially contacts a plurality of teeth formed along the ring's interior surface. The stream of air generated by fan 120 contacts bubble solution retained in the plurality of teeth formed along the interior surface of the ring and causes at least one bubble to be formed. Bubble forming substrate 135 may be formed of any material, including without limitation, a polymer, a metal, an alloy, a composite, paper, or cardboard.
Tube 140 may operatively connect solution container 145 to bubble forming substrate 135. In one embodiment, tube 140 is operatively connected to at least one pressure clasp 150, which is configured to apply pressure to tube 140 or remove pressure from tube 140 and cause bubble solution to progress from solution container 145 to bubble forming substrate 135. In one embodiment, the at least one pressure clasp 150 is operatively connected to cover 175 such that upon opening the cover, the at least one pressure clasp 150 is configured to interact with tube 140 and permit flow of bubble solution from sample container 145 to bubble forming substrate 135. In another embodiment, tube 140 is operatively connected to at least one circular gear (not shown), which is operatively connected to motor 115. The circular gear is configured to rotate upon activation of motor 115 and provide pressure to tube 140 or remove pressure from tube 140 and cause bubble solution to progress from solution container 145 to bubble forming substrate 135. Tube 140 may be formed of any material, including without limitation, rubber, a polymer, a metal, an alloy, and a composite.
Solution container 145 is configured to contain bubble solution until the bubble solution is transported to bubble forming substrate 135 by tube 140. In one embodiment, solution container 145 is selectively sealed such that a gas or liquid cannot pass into or from the solution container until a user permits the gas or liquid to pass into or from the solution container. Solution container 145 may be sealed such that bubble solution contained therein is not able to flow into tube 140 until activation of greeting card 100. Solution container 145 may be sealed such that air is prevented from entering into solution container 145 until activation of greeting card 100, such that bubble solution is not contaminated or caused to dry out. In another embodiment, solution container 145, in conjunction with tube 140, comprises a sealed unit capped by pressure placed on tube 140 by at least one of pressure clasp 150 or a circular gear (not shown). In one embodiment, solution container 145 is sealed with an internal pressure greater than atmospheric pressure, such that upon activation of greeting card 100, the seal in solution container 145 is broken and bubble solution contained therein is permitted to flow into tube 140 under a pressure greater than atmospheric pressure. In one embodiment, solution container 145 is sealed until a user applies pressure to solution container 145, for example, by squeezing solution container 145. This same application of pressure by a user may additionally cause bubble solution to be forced from solution container 145, into tube 140, and ultimately to bubble forming substrate 135. In another embodiment, solution container 145 is pressurized and sealed until a user removes the seal from solution container 145, for example by pulling a string attached to the seal which allows bubble solution to travel from solution container 145, into tube 140 and ultimately to bubble forming substrate 135. Such string may also be pulled automatically upon opening of the card. Solution container 145 may be formed of any material, including without limitation, rubber, a polymer, a metal, an alloy, and a composite.
At least one pressure clasp 150 is configured to interact with tube 140 and permit flow of bubble solution from sample container 145 to bubble forming substrate 135. In another embodiment, at least one pressure clasp 150 is directly attached to cover 175 and configured such that opening of cover 175 manipulates at least one pressure clasp 150 such that it interacts with tube 140 and permits flow of bubble solution. At least one pressure clasp 150 may be formed of any material, including without limitation, rubber, a polymer, a metal, an alloy, and a composite.
As illustrated in FIG. 1, greeting card 100 is configured such that when cover 175 is opened switch mechanism 125 is activated and creates a circuit between energy storage device 110 and motor 115. At least substantially simultaneous to this action, at least one pressure clasp 150 is manipulated upon opening of cover 175, such that at least one pressure clasp 150 interacts with tube 140 and causes bubble solution to flow from solution container 145, through tube 140 and into bubble forming substrate 135. Motor 115, having been activated upon completion of the circuit between motor 115 and energy storage device 110, turns geared output shaft 165, which interacts with geared input shaft 170, thus causing input shaft 170 to rotate. Rotation of input shaft 170 causes fan 120 to rotate, creating a stream of air channeled through air shaft 130 to bubble forming substrate 135. The bubble solution contained in teeth formed on the interior surface of the bubble forming substrate 135's ring interacts with the stream of air produced by fan 120 and creates at least one bubble. In one embodiment, a plurality of bubbles are formed and projected away from greeting card 100 by the stream of air produced by fan 120.

Card Featuring Manual Bubble Feature
FIG. 9 illustrates another embodiment of an example arrangement of a greeting card having an integrated bubble feature. It should be noted that while specific embodiments of the invention reference a greeting card, the invention may extend to any novelty item that may include the use of a bubble generation feature, including without limitation gift boxes, product packaging, and toys. Greeting card 900 includes a frame 905, a bubble forming substrate 910, an aperture 915, a tube 920, and a solution container 925.
In one embodiment, tube 920 operatively connects solution container 925 to bubble forming substrate 910. Solution container 925 may be formed of any material, including without limitation, rubber, a polymer, a metal, an alloy, and a composite. In one embodiment, solution container 925 is formed of a flexible material having a pliable structure, such as a rubber or a polymer, which permits a user to apply pressure to solution container 925, for example, by squeezing solution container 925. The application of pressure to solution container 925 may cause one or more of: breaking the seal on solution container 925, causing bubble solution to exit solution container 925, causing bubble solution to enter tube 920, and causing bubble solution to be transported to bubble forming substrate 910. In one embodiment, solution container 925 is selectively sealed such that a gas or liquid cannot pass into or from the solution container until a user permits the gas or liquid to pass into or from the solution container.
Aperture 915 may include a hole extending from an exterior surface of card 900 to bubble forming substrate 910. In one embodiment, aperture 915 extends through frame 905 from a front surface in the proximity of bubble forming substrate 910 to a back surface. In another embodiment, aperture 915 is positioned substantially within the ring of bubble forming substrate 910. Aperture 915 may be of a width such as to permit flow of an adequate volume and rate of air, such that bubbles may be formed as the air passes through bubble forming substrate 915. Aperture 915 may additionally include one or more of a mouthpiece, nozzle, check valve, cap, and plug.
In one embodiment, greeting card 900 is configured such that a user applies pressure to solution container 925, causing bubble solution to travel to bubble forming substrate 910 via tube 920. Once bubble solution is applied to bubble forming substrate 910, a user may blow air through the user's mouth, and direct the stream to pass through bubble forming substrate 910 and aperture 915, thus creating bubbles. In one embodiment, a user may blow air from a front surface of card 900, a rear surface of card 900, or both. In another embodiment, aperture 915 is eliminated, and bubble forming substrate 910 is offset from a surface of frame 905 a distance adequate to permit enough air flow through bubble forming substrate 910 to produce at least one bubble. In another embodiment, greeting card 900 is configured such that a user may cause an air stream to pass through aperture 915 and bubble forming substrate 910 using any means, for example, by placing card 900 in wind, waving card 900 through the air rapidly, and placing card 900 in front of an air stream source.
FIG. 10 illustrates another embodiment of an example arrangement of a greeting card having an integrated bubble feature. Greeting card 1000 includes a frame 1005, a bubble forming substrate 1010, and a tube 1020 operatively connected to bubble forming substrate 1010 and a solution container 1025. Tube 1020 may be configured to transport a bubble solution from solution container 1025 to bubble forming substrate 1010. In one embodiment, solution container 1025 is selectively sealed such that a gas or liquid cannot pass into or from the solution container until a user permits the gas or liquid to pass into or from the solution container.
Greeting card 1000 additionally includes a spring device 1030 having an output gear 1035. Output gear 1035 may be operatively connected to input shaft 1040, which may include a gear portion configured to interact with output gear 1035.

Fan 1045 is located in substantial proximity to bubble forming substrate 1010 such that an air stream generated by fan 1045 will pass near or through bubble forming substrate 1010 thus creating at least one bubble.
Card 1000 additionally includes a circular gear 1050 operatively connected to tube 1020 and configured to interact with tube 1020. In one embodiment, rotation of circular gear 1050 causes at least one circular gear 1050 to interact with tube 1020, thereby causing bubble solution to flow from solution container 1025, through tube 1020 and into bubble forming substrate 1010.
Card 1000 may additionally include a pull string 1055 operatively connected to spring device 1030. Pull string 1055 may be made of any material, including without limitation, yarn, thread, textile, rope, or cable, or of any of the following: a polymer, a metal, an alloy, or a composite. Pull string 1055 may optionally include a pull handle, which may be made of any material, including without limitation, a polymer, a metal, an alloy, or a composite. In one embodiment, pull string 1055 may be in communication with a seal in solution container 1025, such that pulling string 1055 also breaks the sale in solution container 1025, allowing bubble solution to travel into tube 1020.
Spring device 1030 may include any mechanical energy storage device. In one embodiment, spring device includes a spiral spring configured to be biased in one rotational direction. The spiral spring may be connected to a shaft positioned within the spring. One or more of the shaft and spiral spring may be operatively connected to frame 1005. Pull string 1055 may be attached to the shaft and wrapped around it such that upon pulling pull string 1055, the shaft is rotated in a direction opposite that in which the spiral spring is biased. Upon release of pull string 1055, the spiral spring causes the shaft to rotate in the direction in which the spiral spring is biased. The shaft may be operatively connected to output gear 1035, such that rotation of the shaft causes rotation of output gear 1035.
In one embodiment, a user pulls pull string 1055, causing spring device 1030 to be loaded with mechanical energy. Upon release of pull string 1055, output gear 1035 rotates, causing input shaft 1040 to rotate, which thus causes fan 1045 to rotate. Output gear 1035 additionally causes circular gear 1050 to rotate. Circular gear 1050 is operatively connected to tube 1020, such that rotation of circular gear 1050 causes bubble solution from solution container 1025 to be transferred to bubble forming substrate 1010. An air stream generated by fan 1045 at least substantially contacts bubble forming substrate 1010 so as to create at least one bubble.
FIG. 11a illustrates another embodiment of an example arrangement of a greeting card having an integrated bubble feature. Greeting card 1100 includes a frame 1105, a bubble forming substrate 1110, and a tube 1120 operatively connected to bubble forming substrate 1110 and a solution container 1125. Tube 1120 may be configured to transport a bubble solution from solution container 1125 to bubble forming substrate 1110.
Greeting card 1100 additionally includes a spring device 1130 having an output gear 1135. Output gear 1135 may be operatively connected to input shaft 1140, which may include a gear portion configured to interact with output gear 1135. Input shaft 1140 is operatively connected to a fan 1145. In another embodiment, spring device 1130 is operatively connected to fan 1145. Fan 1145 is located in substantial proximity to bubble forming substrate 1110 such that an air stream generated by fan 1145 will pass near or through bubble forming substrate 1110 thus creating at least one bubble.
Card 1100 additionally includes a circular gear 1150 operatively connected to tube 1120 and configured to interact with tube 1120. In one embodiment, rotation of circular gear 1150 causes at least one circular gear 1150 to interact with tube 1120, thereby causing bubble solution to flow from solution container 1125, through tube 1120 and into bubble forming substrate 1110.
As illustrated in FIG. 11b, card 1100 may additionally include a crank handle 1155 operatively connected to spring device 1130.
In one embodiment, a user rotates crank handle 1155, causing spring device 1130 to be loaded with mechanical energy. Upon release of crank handle 1155, output gear 1135 rotates, causing input shaft 1140 to rotate, which thus causes fan 1145 to rotate. Output gear 1135 additionally causes circular gear 1150 to rotate. Circular gear 1150 is operatively connected to tube 1120, such that rotation of circular gear 1150 causes bubble solution from solution container 1125 to be transferred to bubble forming substrate 1110. An air stream generated by fan 1145 at least substantially contacts bubble forming substrate 1110 so as to create at least one bubble.
In one embodiment (not shown), a greeting card includes a frame, a bubble forming substrate, a tube operatively connected to bubble forming substrate, and a solution container. Tube may be configured to transport a bubble solution from solution container to bubble forming substrate. In one embodiment, the solution container includes a seal to keep bubble solution contained within the solution container, and keep air out of the solution container. A user may squeeze the solution container to cause solution to travel from the tube to the substrate. In another embodiment, the solution container is pressurized at a pressure greater than atmospheric pressure, and includes a seal. A user may squeeze the solution container, causing the seal to break, and bubble solution may be forced out of the solution container and into the tube to the bubble forming substrate. In one embodiment, the tube may be eliminated, such that the solution container directs bubble solution to the bubble forming substrate directly. In another embodiment, the bubble forming substrate is directly connected to the solution container.
In one embodiment, an air container is also provided. The air container may be a pressurized container holding air that is at a pressure greater than atmospheric pressure. The air container may comprise a seal configured to keep air within the air container. In one embodiment, a user may squeeze the air container, causing the seal to break and causing air to travel out of the container. In another embodiment, a user may pull a string attached to the air container, which will cause the seal to break and air to travel out of the container. In one embodiment, air from the air container propels bubble solution out of the solution container. In one embodiment, the air container is configured to supply air to the bubble forming substrate. In one embodiment, the air container is contained within the solution container. In another embodiment, the air container is separate from the solution container.
To the extent that the term “includes” or “including” is used in the specification or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed (e.g., A or B) it is intended to mean “A or B or both.” When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995). Also, to the extent that the terms “in” or “into” are used in the specification or the claims, it is intended to additionally mean “on” or “onto.” To the extent that the term “selectively” is used in the specification or the claims, it is intended to refer to a condition of a component wherein a user of the apparatus may activate or deactivate the feature or function of the component as is necessary or desired in use of the apparatus. To the extent that the term “operatively connected” is used in the specification or the claims, it is intended to mean that the identified components are connected in a way to perform a designated function. Finally, where the term “about” is used in conjunction with a number, it is intended to include ±10% of the number. In other words, “about 10” may mean from 9 to 11.
As stated above, while the present application has been illustrated by the description of embodiments thereof, and while the embodiments have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the application, in its broader aspects, is not limited to the specific details, illustrative examples shown, or any apparatus referred to.
