The present application relates to a magnetically-biased extendable spout for use with containers.
Pouring a liquid from a conventional bottle, such as a glass or plastic bottle with a neck and round mouth, can result in drips running down the side of the bottle when the bottle is returned to an upright position. The liquid also typically pours from such a mouth in a somewhat unpredictable manner that can lead to spills. Fewer drips and spills occur if the bottle is provided with a spout.
A conventional screw top lid is usually incompatible with a spout. An after-market spout may be used to aid in pouring accuracy once the lid is removed. Spouts for wine or liquor bottles typically push-fit into the mouth of the bottle and need to be removed before the lid or a cork is replaced on the bottle.
U.S. Pat. Nos. 6,026,994 and 6,976,610 describe spring-loaded spouts that may be incorporated into a bottle design. The spring-loaded spout is designed to pop-up to an extended position to facilitate pouring.
Reference will now be made, by way of example, to the accompanying drawings which show example embodiments of the present application, and in which:
a and 7b show an example of a two-piece spout.
c and 7d show a cross-sectional view of the two-piece spout.
Similar reference numerals may have been used in different figures to denote similar components.
In accordance with the present application, there is provided a spout assembly configured to be attached to a mouth of a container. The spout assembly includes a cap having an upper surface and defining an axial passageway; a spout mounted within the cap and movable between a retracted position, in which the spout is disposed within the axial passageway below the upper surface, and an extended position, in which at least a portion of the spout extends above the upper surface; and a first polarized magnet attached to the cap and a second polarized magnet attached to the spout, wherein the first polarized magnet and second polarized magnet magnetically bias the spout to the extended position.
Reference is first made to
The cap 1 may be configured to be removably attached to a bottle or permanently attached to the bottle. For example, in the example embodiment shown in
The cap 1 may further have an inwardly projected flange 3 within the axial passageway 7 below the upper surface 4 of the cap 1. The inwardly projected flange 3 may not be continuous around the interior perimeter of the axial passageway 7. In some embodiments, the inwardly projected flange 3 may include two or more flanges separated by gaps.
In some embodiments, the spout assembly 100 may further include a hinged lid 5 attached to the cap 1. The hinged lid 5 may be attached to the cap 1 by way of a hinge mechanism 6. The hinge mechanism 6 allows the lid 5 to pivot from a closed position, in which the lid 5 blocks the axial passageway 7, to an open position. The lid 5 may, in some embodiments, close against the upper surface 4 of the cap 1. In some embodiments, the upper surface 4 may feature an annular recess around the axial passageway 7 into which the lid 5 fits when in the closed position. In either case, the lid 5 or cap 1 may include one or more seals to prevent leakage of liquid through the closed lid 5.
When the lid 5 is in the closed position, the axial passageway 7 is blocked to prevent the contents of the bottle from spilling out, and the spout 8 is maintained in the retracted position. The lid 5 may be connected to the cap 1 by other means including as a removable lid 5 that fits on to the upper surface 4 of the cap 1. In other embodiments, the spout assembly 100 may include a screw top lid, a snap-on lid, or other lid-type closures for sealing the bottle and holding the spout 8 in the retracted position.
Reference is now also made to
The spout 8 in this example includes an outwardly projected flange 9 which engages the inwardly projected flange 3 of the cap 1 when the spout 8 is in the extended position to prevent the spout 8 from moving beyond the extended position and being removed from the cap 1. Reference is now also made to
As mentioned above, the spout 8 is magnetically-biased toward the extended position. Accordingly, when the lid 5 is removed or is pivoted to the open position, the spout 8 is magnetically urged towards the extended position. The magnetic biasing is established through magnets in the cap 1 and spout 8.
In a first embodiment, a first polarized magnet 10 is attached to the cap 1 and a second polarized magnet 11 is attached to the spout 8. In this embodiment, the first polarized magnet 10 is disposed at the inwardly projected flange 3 of the cap 1 and the second polarized magnet 11 is located at the outwardly projected flange 9 of the spout 8. In this embodiment, the magnets 10, 11 are positioned relative to each other to have poles of opposite polarity facing so that the magnetic bias is an attractive force that draws the two magnets 10, 11 together. With the spout 8 in the retracted position, when the lid 5 is unlocked, the magnetic biasing attracts the outwardly projected flange 9 of the spout 8 towards the inwardly projected flange 3 of the cap 1 causing the spout 8 to move towards the extended position.
In another embodiment, the first polarized magnet 10 may be located elsewhere within or on the inner wall of the cap 1 itself, and the second oppositely polarized magnet 11 may be located in or on the spout 8, provided that the first polarized magnet 10 is at a higher level position than the second polarized magnet 11 when the spout 8 is in the retracted position. The range of extension will be governed by the distance between the two magnets 10, 11 when the spout is in the retracted position since the spout 8 will extend by that distance as the two magnets 10, 11 are drawn together.
In either of these embodiments, the first polarized magnet 10 attached to the cap 1 is located closer to the upper surface 4 of the cap 1 than the second polarized magnet 11 when in the retracted position.
In another embodiment, the first polarized magnet 10 is positioned such that the poles of the two magnets 10, 11 facing each other have the same polarity. In such an embodiment, the magnets 10, 11 exert a repelling force upon each other. The magnets 10, 11 in this embodiment are positioned so as to urge the spout 8 outwards towards the extended position. For example, the first polarized magnet 10 attached or embedded within the cap 1 at a position further from the upper surface 4 of the cap 1 than the second polarized magnet 11 when the spout 8 is in the retracted position. With the two magnets 10, 11 close together in the retracted position and with the second polarized magnet 11 on the spout 8 located ‘above’ (i.e. closer to the upper surface 4) than the first polarized magnet 10, the magnetic biasing pushes the spout 8 away from the first polarized magnet 10, causing the spout 8 to move towards the extended position.
A plurality of polarized magnets may also be used to implement the magnetic biasing for embodiments employing magnets with opposite polarity poles facing or with same polarity poles facing, as described above. It will also be appreciated that in some implementations, one or more of the magnets may be annular or semi-annular, or any other suitable shape.
The magnets 10, 11 may be attached or embedded within the cap 1 or spout 8, as the case may be. Methods for attachment may include adhesives, snap-fit into recesses, or other mechanisms or combinations of mechanisms. In some instances, the magnets may be enclosed within the walls of the cap 1 or spout 8. In some cases, they may be placed within the walls during an injection molding process for forming the parts of the spout assembly 100. Other methods of attaching or embedding the magnets for particular applications will be appreciated by those ordinarily skilled in the art in light of the present description.
The interior of the cap 1 may include various guides, slots, flanges, or other projections to restrict the spout 8 from rotating within the axial passageway 7, thereby restricting the freedom of movement to translational movement between the retracted position and extended position. Cooperating guides, slots, projections, etc., may be present on the spout 8 in some embodiments. For example, in the example shown in
It will be appreciated that the movement of the spout may also be rotational and not only be restricted to translational movement between the retracted position and the extended position. In such example embodiments, the interior of the cap 1 may include any suitable guides, slots, flanges or other projections to guide the directional movement of the spout 8 to the extent desirable for a given implementation.
The spout 8 may include tabs, flanges or other projections to connect the spout 8 to the cap 1, and prevent the spout 8 from being detached from the cap 1 when the spout 8 is in the retracted position. Cooperating slots, projections, flanges, etc. may be present on the cap 1. In the example embodiment shown in
Reference is again made to
Reference is also again made to
In any of the forgoing embodiments, a seal 12 may be provided along at least a portion of the inwardly projecting flange 3 of the cap 1 to prevent leakage of fluids between the flanges 3, 9 when the spout 8 is in the extended position. The seal 12 may be made of rubber, plastic, or other suitable compression sealing materials.
Reference is now made to
The lid 5 may, in some embodiments, be spring biased to pivot to the open position, such that when the locking mechanism 13 is released, the lid 5 tends to open. In some example implementations, the spring biasing may be incorporated into the hinge mechanism 6. In another embodiment, as will be described below, the lid 5 may be alternative or additionally magnetically biased towards an open position.
In some embodiments, the lid 5 may incorporate a vacuum seal feature, such as a pump mechanism for pumping air out of the container when the lid 5 is in a closed position.
Reference is now made to
In the embodiment illustrated in
In yet a further embodiment shown in
As noted above, any one or more of the first, second, third and fourth polarized magnets 10, 11, 17, 18 may be implemented using a plurality of magnets.
Reference is now made to
In some example embodiments of the two-piece spout 19 (not shown), the inner piece 20 may include an opening to allow the outer piece 21 to be disposed within the opening and housed within the inner piece 20 when the two-piece spout 19 is in the retracted position. The outer piece 21 telescopes out of the opening of the inner piece 20 when the two-piece spout 19 is in the extended position.
It will be appreciated that the present application is not limited to two-piece spouts 19 and may include a plurality of piece spouts. For example, embodiments may include three-piece spouts or four-piece spouts. In such embodiments, the inner pieces may be nested within an outer piece when the spout is in the retracted position. Each of the pieces may be configured to telescope apart from each of the adjacent pieces when the spout is in the extended position.
The two-piece spout 19 may be magnetically biased towards the telescoped position shown in
The fifth polarized magnet 22 and sixth polarized magnet 23 in this embodiment are positioned to have poles of the same polarity facing each other, such that they exert a repelling force upon each other, thus urging the two-piece spout 19 into the telescoped position. The fifth polarized magnet 22 in the inner piece 20 is located “lower” or “below” the sixth polarized magnet 23 when in the nested position, so as to cause the outer piece 21 to extend upwards away from the fifth polarized magnet 22.
Reference is now made to
The fifth polarized magnet 22 is located at the upper end of the inner piece 20 and when the two-piece spout 19 is in the retracted position the fifth polarized magnet 22 is proximate the fourth polarized magnet 18. The fourth polarized magnet 18 is positioned so as to have its polarity reinforce the telescoping bias through a repelling force vis-à-vis the fifth polarized magnet 22.
In yet a further embodiment illustrated in
It may not be necessary to include any magnets in the inner piece 20 as illustrated in the example embodiment in
As noted previously, a plurality of magnets may be used to implement the magnetic biasing as described above.
The spout assembly may be formed/molded from any suitable material. In one embodiment, the cap is formed/molded integrally with the container/bottle to which it is permanently attached. The range of materials and/or molding processes that may be suitable for implementing the spout assembly described above will be understood by those skilled in the art having regard to the present description.
Although many of the examples described above made specific reference to attachment to bottles, it will be appreciated by those skilled in the art that the spout assembly is not limited in application to bottles. The spout assembly may be configured to be attached to the mouth of other containers. For example, in some example embodiments, the spout assembly may be configured to be attached to the mouth of a jar or a canister, such as a gasoline canister.
Certain adaptations and modifications of the described embodiments can be made. Therefore, the above discussed embodiments are considered to be illustrative and not restrictive.
