Description
DRINKING STRAW FOR PROPORTIONING CONCENTRATE AND DILUENT IN THE MOUTH
Field of the Invention The present invention relates to drinking straws for beverages where the beverage is a mixture of two or more liquid components. With this invention, the components are mixed in the mouth and the mixing ratio is controlled by the user.
Background It is commonly held that there are four basic tastes ¨ sweet, sour, salt and bitter. A
misconception, widely held, is that different areas of the tongue exclusively detect different basic tastes. The tip of the tongue, for example, was once thought to only taste sweet. This myth has been debunked; nevertheless, it is a fact that taste buds are concentrated around the perimeter of the tongue. The present invention directs the flavoured components of a beverage to taste sensitive areas of the tongue and the unflavoured component to areas insensitive or less sensitive to taste.
The invention has been primarily developed for imbibing beverages which are commonly prepared by combining two or more liquid components, usually including a flavour concentrate and a diluent.
When used to consume soft drinks comprised of syrup and carbonated water, the present invention allows the user to reduce the intake of syrup relative to carbonated water while still experiencing the full taste of the syrup since the syrup is being directly conveyed to the taste sensitive areas of the tongue.
The physics of Fluid mechanics holds that as a fluid moves through a conduit, the fluid in contact with the outer walls is motionless and that the velocity of the fluid increases with distance from the outer walls. In the case of a fluid travelling through the mouth, the fluid close to the tongue travels much slower than the fluid slightly farther away. If syrup is introduced near the surface of the tongue it will travel over the surface of the tongue at a velocity slower than the carbonated water above, lingering over the taste buds and giving the impression to the user of the invention that the liquid is richer in syrup than it actually is.
The tubes referred to could also be called basic drinking straws or siphons.
A person using a straw to drink a liquid can increase the velocity at which the liquid enters the mouth by increasing the vacuum in the mouth. This is called sucking and is one of the most basic instincts. The rate at which a liquid enters the mouth through a drinking straw may be reduced by plugging or partially plugging the end of the tube with the tongue or by reducing the vacuum in the mouth. One may use the tongue, in effect, as a valve to control the flow into the mouth from the tube.
In the case of the invention, at least two tubes (11, 12) enter the mouth. The diluent tube (11) enters the mouth at the lips (16) and the flow in the diluent tube (11) is controlled through sucking action. The concentrate conveying tube (12) contacts the tongue and the flow is regulated, relative to the flow of diluent, by either blocking, partially blocking or unblocking the end of the tube (12) with the tongue (15).
Soft drinks are prepared by combining syrup with carbonated water. For the purpose of explaining the function of the invention for imbibing soft drinks, the syrup is the flavour concentrate and the carbonated water is the diluent. There is no calorie content in carbonated water. Imbibing carbonated water hydrates the body and has other beneficial effects. On the other hand, soft drink syrup is either high in sugar or contains artificial sweetener. There is a perception among some that artificial sweeteners are carcinogenic or otherwise bad for one's health. Sugar consumption is problematic for those trying to control their weight or their blood sugar. The invention allows the user to control, in the mouth, the ratio of syrup to carbonated water thereby reducing the intake of sugar or artificial sweeteners. In addition to providing the user with this control, the invention delivers the syrup directly to the tongue. If the syrup covers the taste sensitive areas of tongue, the user perceives that the beverage is rich in syrup, when in fact only a portion of the mouth contains syrup. To their benefit, the user may consume less sugar or artificial sweeteners and more water.
The benefits of this invention are not limited to soft drinks. Like soft drinks, highballs are drinks made by mixing two liquid components together. In the specific example of a "Screwdriver", vodka and fresh orange juice are combined. The user of the invention may perceive that their mouth is full of vodka, when, in fact, it is primarily filled with orange juice. The user therefore may adjust the mix ratio in order to consume less vodka and more orange juice which is a much healthier situation. Another example would be chocolate milk. Chocolate syrup is high in sugar, the consumption of which may lead to high blood sugar. It is also high in calories; the consumption of too many calories can cause obesity. On the other hand, milk is very nutritious.
The invention could be used for milk and chocolate syrup with benefit to the user. Often, the flavour concentrate is higher in calories than the diluent and, in those cases, the invention can be used to reduce calorie intake.
The benefits of the invention are not limited to reducing the consumption of calories, sugar, artificial sweeteners and alcohol. Flavour concentrates, high in salt, such as condensed beef broth, could be imbibed with hot water using the invention with healthier consequences.
Generally, the diluent is a less expensive than the flavour concentrate and therefore use of the invention could impart financial in addition to health benefits to the user.
Prior Art A design in the prior art, Canada Patent Number 2 240 716, describes an apparatus for adding a beneficial agent to a liquid. The beneficial agent is a powder or solid, not a liquid. Another design, Canada Patent Number 4 487 432, describes an elongated tube containing flavouring concentrate in the form of solid pellets intended to be used as a drinking straw. Canada Patent 2 620 628 describes a hollow tube coated on the inside with an edible composition. Canada Patent 2 621 747 describes a drinking straw filled with food. Canada Patent 2 644 062 describes a drinking straw filled with pellets which adds an active ingredient to liquid passing through. In none of these designs is the mixing taking place in the mouth nor are all the components liquids. The prior designs remain useful for their stated purposes while the present invention provides the user the health and financial benefits of moderation while allowing them to continue to enjoy their favourite beverages.
Legend and List of Figures The figures use the following legend:

Flavour Concentrate 20. Optional /Complementary Flavour Concentrate 21. Diluent ( e.g. Carbonated Water and Ice) 22. Pierceable pouch surface, disc or liquid boundary Figure 1 shows the simplest version of the invention. A tube (11) conveys diluent (21) from the cup (18) to the mouth at the lips (16). A tube (12) conveys flavour concentrate (19) from the bottom of the cup (18) to the tip of the tongue (15).
Figure 2 is similar to figure 1 with a diffuser (14) added to the end of the flavour concentrate tube (12). The diffuser (14) serves to distribute flavour concentrate over taste sensitive areas on the surface of the tongue (15).
Figure 3 is similar to figure 2 except that the flavour concentrate conveying tube (12) runs through the diluent conveying tube (11).
Figure 4 is similar to figure 2 with an additional tube (13) conveying a different, separate and distinct flavour concentrate (20) from the cup (18) to the diffuser (14) on a different taste sensitive area of the tongue from that of the diffuser (14) attached to the end of tube (11).
Examples of Intended Use Please refer to figure 1. One way of using the invention would be to put a small amount of flavoured syrup (19) in the bottom of a cup (18) and fill the balance of the cup with ice and carbonated water (21). Place the invention (11, 12) in the cup (18) with the upper end of the invention (11, 12) in the mouth with the tube (11) just inside the lips (16) and the tube (12) touching the end of the tongue (15) where the taste buds are concentrated. By partially blocking the end of the tube (12) with the tongue (15), the user is able to vary the ratio of carbonated water (21) to syrup (22) to the user's own liking and can allow the syrup (22) to linger on the tongue (15) while the carbonated water (21) is swallowed. In the most basic configuration, the difference in the specific gravity between the denser flavoured syrup (19) and the lighter carbonated water (21) is relied upon to keep the two liquids separate in the cup.
Please refer to figure 4. Figure 4 illustrates a more elaborate expression of the invention. For this second example, we use the invention to enjoy a Spanish coffee. The first flavour concentrate (19) would be 15 mL coffee liqueur (19), the optional additional flavour concentrate (20) would be 15 mL orange brandy (20) and the diluent (21) would be 120 mL of fresh hot coffee (21). The amount of liqueur (19 and 20) in this example is intended to be about half of that in a typical Spanish coffee. Reducing the amount of liqueur imbibed and by extension the amount of alcohol imbibed is a health benefit to the user.
15 mL of coffee liqueur (19) would be placed in the bottom of a glass (18) and a wax paper disc (22) would be placed on the surface (22) of the coffee liqueur (19). This disc (22) would have the same diameter as the glass at the surface (22) of the coffee liqueur and have a hole in it in a convenient location, the same diameter as the tube (19) in order to accommodate the tube (19).
15 mL of orange brandy (20) would be carefully layered on top of the wax paper disc (22).
Another wax paper disc (22) the same diameter as the glass at the surface of the orange brandy (20) with two holes conveniently located and sized to accommodate the two tubes (12 and 13).
120 mL of fresh hot coffee (21) would be carefully layered above the disc (22). When the user sucks on the invention inserted in the mouth as illustrated, coffee enters the mouth above the tongue (15) and below the palate, while coffee liqueur (19) is supplied to one side of the tongue (15) through tube (13) and distributed over taste sensitive areas of the tongue (15) by means of a divergent nozzle or diffuser (14). With the diffuser, coffee liqueur (19) is protected from being washed off the surface of the tongue because the material of the diffuser stands between the diluent and the flavour concentrate.
If a pouch is attached to the container end of the long tube, the pouch would be filled with flavoured syrup and placed in the bottom of the container or cup.
Alternatively, the longer tube may be connected to the pouch which in turn is attached to the side of the container or cup while the shorter tube is inserted into the container or cup.
The diluent and the flavour concentrate may be kept distinct and unmixed by a number of means. The easiest, most economical way is to let gravity keep them separate.
The drink components may be carefully layered into the cup in the same way a mixologist might make a Shirley Temple. The denser liquids are placed closer to the bottom of the cup and gravity keeps them separate. A disc or discs may be used to keep the liquids separate. Each disc would have holes in it to allow one or more tubes through into liquid or liquids below. A
liquid component such as the flavour concentrate may be placed in a pouch and that pouch placed in the cup or attached to the side or bottom of the container. In some cases, the difference in the polarity of the different components can be relied on to keep the component liquids separate. A difference in density is also required because even though the components of different polarity won't mix, it is necessary that the components stay in place relative to each other. In other words, the flavour concentrate must stay below the diluent and if the specific gravity of the two liquids is the same, they could end up side by side instead of one on top of the other.
