The present invention relates generally to a device to aid in pouring, transferring and/or drinking liquids and, more particularly, to a novel flexible pouring spout, spill guard and drinking aid that can be easily and firmly affixed to, and removed from, pots, pitchers, glasses, mugs or other similar vessels or container that hold liquids and provides means for facilitating and controlling the flow of such liquids out of such vessels or containers.
One particular area for which the present invention can be applied pertains to preparing baby formula. As the cost of microwave ovens has fallen substantially over the past two decades, microwave ovens have become fixtures in more and more household kitchens. These ubiquitous appliances are now used to heat a wide variety of food and beverage products, including baby formula. Milk or baby formula that is placed into a mug or glass and then warmed in a microwave is difficult to pour into a baby bottle without spillage due to the small opening for the bottle. While a traditional funnel can be used for transferring liquids from a mug to a baby bottle, the nature of the small passageway in such a funnel makes them difficult to clean, as might the materials from which they are made, all of which can lead to milk residue being built up over time, presenting potential health concerns or hazards.
Additionally, the average individual faces obstacles whenever trying to transfer the contents from any vessels that have been heated in a microwave to bottles or containers without the contents spilling or running down the outside of those bottles or containers. As a result, kitchens are increasingly stocked with microwave safe dishes, bowls, glasses and mugs. Along with defrosting and cooking frozen foods, microwave ovens are used to heat soups and to even boil water, for example before transferring the heated water into an insulated tumbler in order to make coffee or tea and which can be carry taken in the car or on public transit. Transferring these heated liquids presents difficulties, as the lips of glasses and mugs are prone to spillage when liquids are being poured. Similarly, soup warmed in a bowl or large mug is not easily transferred to an insulated beverage bottle, such as a Thermos® insulated container. It is the object of the present invention to provide a means for transferring liquids from one vessel to another that overcomes the deficiencies of the prior art.
Thus, the present invention is an improved pouring spout guard used for easily transferring liquids among or between vessels, bottles and/or containers without leaking, and which can also be used to provide more control over the flow of liquids when drinking out of such vessels or containers.
This relates to a removable pour spout that aids in pouring liquids out of a variety of vessels, including, but not limited to, cooking vessels or drinking vessels, such as glasses, tumblers or mugs, either into bottles or other vessels or containers, or into a user's own mouth. Additionally, because mugs, glasses and other vessels are used to hold heated liquids, or can even be used to hold liquids while they are heated in microwave ovens, any such pouring aids must provide hands-free means for controlling the flow of liquids between the vessels and the containers and should avoid, or substantially reduce, the possibility of spills and burns.
Funnels and spouts have long been used in improving one's control over the flow of liquids when transferring them out of, or between, different vessels, containers, cooking pots, bowls, storage products and other items used to hold or deliver liquid contents, and various funnels and pour spouts can be found in the prior art. Many of these prior-art pouting spouts are of substantially fixed or rigid structures of a specific size, and are designed to be used with only vessels or containers of matching size, which limits their usefulness. Because they lack flexibility, it may be difficult for users of such spouts to securely attach them to a particular vessel or container, resulting in reduced usefulness and an increase in the likelihood of spills occurring and/or requiring the purchaser to secure multiple spouts of different sizes. Many of these rigid funnels and spouts are also not safe to use repeatedly with heated liquids; in fact, plastic not treated to handle extreme temperatures and the materials will degrade over time through repeated exposure to heated liquids, or otherwise and may become brittle or altered when exposed to extremes of heat or cold. Other prior art spouts that are flexible are not capable of creating a sufficiently strong and sealed connection with the vessels or containers to which they are applied and are thus prone to leaks and spills.
While some liquid transfers might be manageable using a funnel, funnels are not always optimal for transferring all types of beverages and liquids. Most funnels are made from simple plastic or metal materials, which can make them hard to manage when dealing with heated liquids, and can make cleaning more difficult. Additionally, the size of the opening in the funnel stem may not always be sufficiently wide so as accommodate the contents of all liquids, particularly those also containing solid matter, such as chili or heated soup containing pieces of chicken or vegetables. Depending on the properties of the materials from which they are manufactured, using a funnel for transferring liquid that is hot can sometimes impact on the taste of the beverages themselves. Additionally, the content of the liquid may negatively impact on the funnel or its integrity. For example, tomato-based soups may stain a plastic funnel or leave a residue that is not easily removed.
Furthermore, funnels can at times be difficult for a single person to use, as their proper use normally requires the use of 3 hands (one to hold the receiving container, one to hold the funnel and one to hold the pouring vessel), making funnels prone to spills or burns when utilized by a single individual. Because a funnel's stem extends down into body of the receiving vessel, the funnel needs to be lifted up during the pouring process in order to finish filling the receiving container. When a heated liquid is being transferred, holding or lifting the funnel can cause burns, discomfort, or even lead to the user knocking over or dropping the receiving container during the pouring process. It is the object of the present invention to provide a pouring spout that overcomes the limitations imposed by plastic funnels.
Additionally, funnels would not address the difficulties faced by persons attempting to transfer liquids from one glass or mug to another glass or mug (or similar wide-mouthed vessel), such as when dividing or splitting a glass of juice or a mug of coffee, which activities normally are undertaken outside of the kitchen where funnels would be kept. Because of the manner in which the lips of these vessels are formed, they are prone to spilling when pouring from one to another, even when the first is perfectly positioned to pour the contents into another vessel. The width of the stream of liquid being poured is not controlled or limited in any way by the top edges of the glasses or mugs, and as a result the stream of liquid being poured may be excessively wide and may even extend beyond the size of a funnel. Spills also often occur down the sides of the glasses or mugs themselves. Such spills or drips can often occur when liquid is drunk directly from the vessels, a problem that funnels would not be used to address.
Therefore, on account of the above, there is a continuing and unmet need for a novel device that can be applied to any type of liquid container or vessel, such as a glass, tumbler or mug, and used to assist in drinking from or transferring liquids out of those vessels to bottles, containers or other vessels without spillage. The tool should be able to accommodate different size beverage holders, able to withstand heat and cold, reusable, portable, chemically inert when exposed to fluids, resistant to melting or staining, and easy to clean.
The present invention provides an improved detachable liquid pouring spout Once secured to a liquid-holding vessel, the improved pouring spout aids in transferring liquid out of the vessel while reducing or eliminating spills.
Certain embodiments of the present invention include but are not limited to the following. An aspect of the present invention is to provide a novel flexible, detachable pouring spout guard that is applied to the rim of glasses, mugs or other vessels or containers used for holding liquids and is employed to facilitate the transference of liquids from such vessels to bottles, such as baby bottles, or other fluid or beverage containers or vessels. Such a pouring spout guard is desirable because these vessels can be used for holding liquids that are heated in microwave ovens or on a stove-top, and the liquid then transferred to smaller and/or more portable fluid or beverage containers, whose openings are frequently too small to permit the transfer of liquids from the heating vessels without spilling the heated liquids, or else divided among multiple containers or vessels.
By way of example, a parent may choose to warm baby formula or breast milk in a steel pot or a microwave oven by using a microwave oven-safe vessel or container such as a mug, glass, cup or bowl. The pouring spout guard of the present invention is therefore desirable because it can be applied to the vessel or container either before or after heating and used in the safe transfer of heated liquids to smaller and/or more portable fluid or beverage containers, such as baby bottles. Because the openings of baby bottles are generally small, the pouring spout guard permits the easy transfer of liquids from the microwaved vessels to the baby bottles with little or no spilling of the heated liquids.
The spout guard is fabricated from highly water-repellant, food safe, rubbery material (thermoset or thermoplastic) that is naturally or synthetically made. The preferable materials of manufacture for this pouring spout are silicone rubber (thermoset elastomer), and thermoplastic rubbers (thermoplastic elastomer) such as thermoplastic polyurethane (TPU), thermoplastic styrene (TPS), thermoplastic vulcanizates (TPV), and any other similar plastic rubber materials that allow the pouring spout guard to bend and yet be able to keep its original design and shape. The product can also be made out of thermoplastic polymer materials that can be recycled, such as polyvinyl chloride (PVC) soft materials or polyamide (PA) flexible nylon materials.
The pouring spout guard is curved with a rounded central channel formed by opposing inner and outer wall elements, and is designed to fit over the lip of a glass, mug, cup or similar vessel. The outer wall contains a latching element with a hook shape at the bottom while the inner wall contains a plurality of fixed gripping teeth elements, separated by grooves; together, these elements function as a latch spring mechanism that combines with the friction coefficient of the materials used in the manufacturing process and keeps the pouring spout guard firmly affixed during use. The plurality of gripping elements and the grooves between them, when combined with the elastomeric qualities of the manufacturing materials, enables the degree of curvature of the pouring spout guard to be increased or reduced, thereby allowing the pouting spout guard to be applied to different sized drinking vessels. The pouring spout guard of the present invention is designed so that its degree of curvature easily can be increased or reduced in order to accommodate the rims of glasses or mugs having openings of different circumferences. Further, the use of flexible manufacturing materials allows the product's rounded central channel to fit over vessels having a variety of lip thickness.
The improved pouring spout also reduces the likelihood of spilling the liquid as it leaves the vessel to which the pouring spout guard is affixed. The inner wall extends downward below the level of the outer wall latching element and the grooves formed in the inner wall between the multiple gripping teeth elements are of limited height in order to prevent water from seeping into the space between the inner wall element and the inner surface of the vessel. The counterbalanced forces produced by the outer latching lip and inner latching elements prevents liquids from leaking into the space between the inner wall of the pouring spout guard and the interior surface of the vessel, reducing dripping and spillage. Additionally, the pouring surface portion of the pouring spout guard utilizes a curvature, a small protrusion or bump on each side of the pouring surface, and an extended lip, all working in combination to direct the liquid into a centralized pouring area, thereby narrowing the width of the stream of liquid during the pouring process and reducing the chances of spillage. The pouring surface of the pouring spout guard starts broadly on the side aligning with the interior edge of the vessel and narrows towards the pouring lip portion that extends outside of the vessel, and utilizes the bumps on each side of the pouring spout to aid in channeling the liquid onto the pouring surface and into a narrower stream flowing over the pouring lip, thereby also helping to reduce or eliminate spills.
In one embodiment of the present invention, the removable pouring spout guard can be attached to a vessel used for heating liquids, such as a small cooking pot or any of a variety of beverage containers, including, but not limited to, glasses, mugs or tumblers used in holding heated liquids, or other microwave-safe vessels used for heating liquids in a microwave. Such a spout is desirable because it can be applied to the lip of the vessel containing these warmed liquids and used to transfer the liquids to smaller and/or more portable containers, including, but not limited to, Thermos® insulated containers or other transportable bottles or containers, whose openings are frequently too small to permit the transfer of liquids from the heating vessels without spilling the heated liquids.
In another embodiment of the present invention, the pouring spout guard is used to aid in preparing baby bottles by applying the pouring spout guard to a glass, mug or similar vessel holding heated milk or baby formula and safely and easily pouring such liquids into a baby bottle.
In another embodiment of the present invention, the surface of the sides of the central channel are textured to increase the frictional coefficient of the surfaces, thereby increasing the grip of the pouring spout on the vessels to which it is applied.
In another embodiment of the present invention, the pouring spout is made from materials that have been treated, such as by the addition of a pigment component, so that the pouring spout will change colors when exposed to heat or heated liquids that will warn users of the potential for being burned.
In another embodiment of the present invention, the spout guard is used for drinking directly from mugs, tumblers and other similar vessels; specifically, the spout guard provides a more controlled pouring surface, thereby reducing or eliminating the spills and drips that often occur when drinking from vessels having rounded lips, a function that can benefit small children; the elderly or the infirmed by allowing them means to safely and easily drink a variety of liquids.
Accordingly, with pour spouts several advantages are provided herein, with the presence of an improved means of functionality, portability, flexibility and adaptability.
Finally, as can be appreciated by one in the art, the present invention also comprises a method for forming and using the pouring spout guard described herein.
