Description

CROSS REFERENCE TO PRIOR APPLICATIONS

This application is filed under 35 U.S.C.§120 and §365(c) as a continuation of International Patent Application No. PCT/CA2011/050076 filed Feb. 10, 2011, which application claims priority from U.S. Provisional Patent Application No. 61/348,150, filed on May 25, 2010, which applications are incorporated herein by reference in their entireties.

FIELD OF THE INVENTION

The present invention broadly relates to beverage containers, and, more particularly, to a reusable beverage container with a flexible spout.

BACKGROUND OF THE INVENTION

Beverage containers are well known. Generally, a beverage container includes a receptacle, a spout assembly, and, optionally, a cap.
A problem with prior beverage containers is that the spouts are generally hard and rigid, and, therefore, not tactilely pleasing to a user while consuming the beverage. Hard and rigid spouts and straws are simply not always comfortable in the mouth. Rigid spouts and straws do not conform to the soft tissue of human lips. This poor fit can also cause leakage of the beverage about the circumference of the spout or straw during consumption.
Another problem with prior spouts and straws is that liquid can generally flow freely therethrough. If liquid is allowed to flow freely, it can flow suddenly and unexpectedly, often onto the user's face.
Yet another problem with prior beverage containers is that the spout assembly generally includes multiple components, having separate mechanisms to seal the spout assembly to the receptacle as well as separate valves to regulate liquid flow. This causes the spout assemblies to be less reliable, and more complicated and expensive to manufacture.
Thus, there is a long-felt need for a beverage container with a flexible spout assembly, preferably made of silicone or similar “soft” material, which provides a user with a comfortable feel when engaging the lips of a user. In addition, there is a long-felt need for a beverage container where the liquid flow is restricted, causing the liquid to flow in intermittent surges, i.e., chugs. There is also a long-felt need for a beverage container in which the spout assembly is constructed as a single component.

BRIEF SUMMARY OF THE INVENTION

The present invention is a reusable beverage container including a cap having a first top portion and an inner flange extending downwardly therefrom, a receptacle, a neck portion, and a flexible spout. In one embodiment, the neck portion includes an inner diameter surface and an outer diameter surface. The flexible spout has a through-bore therein, a first opening rim and a second opening rim formed by the through-bore, and an outer surface having a plurality of ribs annularly disposed about the outer surface. Additionally, the flexible spout includes a first portion having a first length and a second portion having a second length. The neck portion is operatively arranged to receive the first portion of the spout. The second portion of the spout extends upwardly beyond the neck portion at a ratio between the first length and the second length which ranges from about 0.8 to about 1.2. The plurality of ribs is sealably engaged against the inner diameter surface of the neck portion and the first opening rim is sealably engaged to the first top portion when the cap is secured to the neck portion. It should be appreciated that in a preferred embodiment, the spout is substantially cylindrical in shape; however, the shape and size of the spout may vary as necessary to conform to and sealably engage the inner diameter surface of the neck portion.
In another embodiment, the reusable beverage container includes a cap having a first top portion and an inner flange extending downwardly therefrom, a receptacle, a neck portion, and a flexible spout. The inner flange has threads disposed along an inner diameter surface of the inner flange. The receptacle and the neck portion include an inner diameter surface and an outer diameter surface, where the outer diameter surface has threads disposed about it. The flexible spout has a through-bore therein. The through-bore has a frusto-conical shaped spout portion having a first opening rim, a tubular channel portion having a second opening rim and an outer surface having a plurality of ribs annularly disposed about the outer surface. Additionally, the flexible spout includes a first portion having a first length and a second portion having a second length. The neck portion is operatively arranged to receive the first portion of the flexible spout. The second portion of the flexible spout extends upwardly beyond the neck portion at a ratio between the first length and the second length which ranges from about 0.8 to about 1.2, and the plurality of ribs is sealably engaged against the inner diameter surface of the neck portion. The first opening rim is sealably engaged with the first top portion when the cap is threadingly secured to the neck portion.
In yet another embodiment, the reusable beverage container includes a cap having a first top portion and an inner flange extending downwardly therefrom, a receptacle and a neck portion, where the neck portion is formed from a first material, and a flexible spout. The neck portion includes an inner diameter surface and an outer diameter surface. The flexible spout has a through-bore therein and a first opening rim, where the flexible spout extends upwardly beyond the neck portion. Furthermore, the flexible spout formed from a second material different from the first material. The first opening rim is sealably engaged to the first top portion when the cap is secured to the neck portion.
A general object of the invention is to provide a reusable beverage container with a flexible spout assembly that provides a user with a comfortable feel when placed in contact with the user's lips.
Another object of the invention is to provide a reusable beverage container where the liquid flow is restricted and does not flow freely through the spout assembly.
Yet another object of the invention is to provide a reusable beverage container in which the spout assembly is a single component and directly engages the receptacle.
These and other objects and advantages of the present invention will be readily appreciable from the following description of preferred embodiments of the invention and from the accompanying drawings and claims.

As also depicted in FIG. 1, handle 47 extends across the diameter of second top portion 21 of cap 13, and is open on both sides. Aperture 41 enables user 90 (not shown in FIG. 9A) to hold beverage container 10 by gripping through aperture 41 and wrapping his or her hand around handle 47 for a secure grip. FIG. 9A is a top perspective view of cap 13 shown in FIG. 9. FIG. 9B is a bottom perspective view of cap 13 shown in FIG. 9.

Embodiment I-A (Long Spout Embodiment)

In the long spout embodiment, as shown in FIGS. 3A, 4, 4A, 5, 6, 7, 7A, 7B, and 11, the spout sealably engages the neck portion of the receptacle. When the spout is inserted into the neck portion, the spout extends upwardly beyond the rim of the neck portion. In a preferred embodiment, the spout extends upwardly approximately 1.905 centimeters above the rim of the neck portion. This dimension is not critical, and is not intended to limit the scope of the appended claims. Perhaps more importantly, in the long spout embodiment, is the ratio of the length of the spout relative to the length of the neck portion of the container. As shown in FIG. 3A, the length “x” of the portion of the spout that extends beyond the rim of the neck is approximately equal to the length “y” of the neck portion itself. In a preferred embodiment, in the long spout embodiment, the ratio y/x is approximately equal to 1, or in the general range of 0.8-1.2.
FIG. 3A is a cross-sectional view of embodiment 1-A of beverage container 10 taken generally along line 3-3 of FIG. 1. We refer to this as the “long spout” embodiment of the invention. In this figure, cap 13 has been removed, such that flexible spout 12 is shown inserted into neck portion 32 of receptacle 11. Neck portion 32 includes inner diameter surface 33, outer diameter surface 34, and rim 27. Neck portion 32 is operatively arranged to receive at least a portion of spout 12. Spout 12 includes through-bore 24, frusto-conical shaped spout portion 23, and tubular channel portion 38, first opening rim 35, and second opening rim 36. In this embodiment, spout 12 extends approximately 1.905 centimeters above rim 27 of the neck portion 32. It should be appreciated that in a preferred embodiment, the spout is substantially cylindrical in shape; however, the shape and size of the spout may vary as necessary to conform to and sealably engage the inner diameter surface of the neck portion.
FIG. 4 is a fragmentary cross-sectional view of beverage container 10 shown in FIG. 3A, illustrating the engagement of spout 12 with user's mouth 91 and lips 93, 94. In use, the lower lip of the user “kisses” the lower surface of the spout, and the upper rim of the spout presses against the upper lip of the user. That is, outer surface 26 of spout 12 is in contact with upper surface 97 of lower lip 94 and first opening rim 35 of spout 12 is in contact with philtral columns 95 of face 92 and that area of face 92 proximate thereto, between nostrils 96 and upper lip 93 proximate the philtrim. Spout 12 may be made of any suitable substantially flexible material, such as silicone, providing user 90 with a soft, comfortable feel when engaged with user's mouth 91 and lips 93, 94 as user 90 drinks from beverage container 10. Silicones form a group of a large variety of synthetic compounds that are polymers, comprising silicon combined with carbon, hydrogen, oxygen, and other chemical elements. Silicone is preferable due to its soft, rubber-like composition, thermal stability, and ability to repel water and form watertight seals. In addition, many forms of silicone have antimicrobial and antibacterial properties.
FIG. 4A is an enlarged cross-sectional view of beverage container 10 shown in FIG. 4. In this figure, the user's upper lip 93 and lower lip 94 enclose first opening rim 35 of flexible spout 12 within user's mouth 91. Due to the soft, flexible nature of spout 12, outer surface 26 of spout 12 conforms to user's mouth 91 and user's lips 93, 94, providing a more enjoyable drinking experience.
FIG. 5 is a fragmentary cross-sectional view of beverage container 10 shown in FIG. 4, depicting liquid 51 flowing in intermittent surges 52, 53, 54, i.e., chugs. As user's mouth 91 and lips 93, 94 engage spout 12 and user 90 begins to drink, liquid 51 flows by means of through-bore 24 into user's mouth 91. Liquid 51 flows in intermittent surges 52, 53, 54 so as to prevent liquid 51 from flowing suddenly and unexpectedly onto user's face 92. Intermittent surges 52, 53, 54 of liquid 51 commence when user 90 tilts beverage container 10 upward to drink liquid 51. Upon tilting beverage container 10, air space 46 is created above liquid 51 within receptacle 11 of beverage container 10. Initial surge 52 of liquid 51 flows out of spout 12 until the air pressure above liquid 51 is decreased, which in turn causes the flow of liquid 51 to cease. Air then enters beverage container 10 through spout 12 forming air pockets, which bubble up through liquid 51 into air space 46. As the air bubbles enter air space 46 of receptacle 11, the additional air increases the pressure in air space 46 enough to initiate second surge 53 of liquid 51 to flow out of spout 12 into user's mouth 91. This cycle repeats until user 90 tilts beverage container 10 upright or beverage container 10 empties.
FIG. 6 is a cross-sectional view of receptacle 11 of beverage container 10 shown in FIG. 3A, with spout 12 removed. Receptacle 11 comprises outer surface 14, inner surface 15, and slightly convex bottom surface 16, and is substantially cylindrical in shape. Outer diameter surface 34 of neck portion 32 includes threads 25 disposed about outer diameter surface 34.
FIG. 7 is a cross-sectional view of an embodiment of spout 12 of beverage container 10. Spout 12 comprises outer surface 26 having plurality of ribs 22 annularly disposed about outer surface 26. Through-bore 24 forms first opening rim 35 and second opening rim 36. Frusto-conical shaped spout portion 23 is in communication with first opening rim 35 and tubular channel portion 38 is in communication with second opening rim 36, such that the diameter of first opening rim 35 is larger than the diameter of second opening rim 36. Spout 12 is easily removed from neck portion 32 (not shown in FIG. 7) of receptacle 11 (not shown in FIG. 7) for easy cleaning or replacement.
FIG. 7A is a bottom perspective view of spout 12 shown in FIG. 7. In this figure, tubular channel portion 38 forms second opening rim 36 on the lower end of spout 12. FIG. 7B is a top perspective view of spout 12 shown in FIG. 7. In this figure, frusto-conical shaped spout portion 23 forms first opening rim 35 on the upper end of spout 12 and tapers towards the center of spout 12.
FIG. 11 is an exploded view of beverage container 10 shown in FIG. 1. FIG. 14 illustrates cap 13, spout 12, and receptacle 11, along a longitudinal axis. When spout 12 is inserted into the neck portion of receptacle 11, spout 12 extends approximately ¾ inch above the rim of the neck portion. In addition, when cap 13, spout 12, and receptacle 11, are secured to one another, cap 13 is flush with receptacle 11.

Embodiment I-B (Short Spout Embodiment)

In the short spout embodiment, as shown in FIGS. 3B, 6, 8, 8A, 8B, 10, 10A, and 12, the spout sealably engages the neck portion of the receptacle similar to the long spout embodiment. However, the spout only extends slightly above the rim of the neck portion. The rim of the neck portion extends upwardly into a channel in the spout to secure the spout to the neck portion.
FIG. 3B is a cross-sectional view of embodiment IB of beverage container 10 taken generally along line 3-3 of FIG. 1. We refer to this as the “short spout” embodiment of the invention. In this figure, cap 13 has been removed, such that flexible spout 12 is shown inserted into neck portion 32 of receptacle 11. In this embodiment, spout 12 extends slightly above rim 27 of neck portion 32. Spout 12 engages rim 27 via channel 48, such that rim 27 extends upwardly into channel 48 to secure spout 12 to neck portion 32. It should be appreciated that in a preferred embodiment, the spout is substantially cylindrical in shape; however, the shape and size of the spout may vary as necessary to conform to and sealably engage the inner diameter surface of the neck portion.
As described previously, FIG. 6 is a cross-sectional view of receptacle 11 of beverage container 10 shown in FIG. 3B, with spout 12 removed.

Receptacle 11 has outer surface 14, inner surface 15 (not shown in FIG. 13) and bottom surface 16 (not shown in FIG. 13). Cap 13 includes first top portion 28 and second top portion 21. First top portion 28 includes raised first cover portion 29, depressed first cover portion 31 (not shown in FIG. 13), sidewall 37 and at least one drainage aperture 45. Second top portion includes handle 47.
FIG. 14 is an exploded view of beverage container 10 shown in FIG. 13. FIG. 14 illustrates cap 13, spout 12, and receptacle 11, along a longitudinal axis. When cap 13, spout 12, and receptacle 11, are secured to one another, cap 13 is flush with receptacle 11.
FIG. 15 is a cross-sectional view of cap 13 of beverage container 10. Cap 13 includes first top portion 28 and inner flange 18. First top portion 28 of cap 13 includes sidewall 37, which has an inner surface 30 and an outer surface 40. Cap 13 further includes outer flange 39 extending downwardly and second top portion 21 including aperture 41. Raised first cover portion 29 is located within the circumference of the upper section of first top portion 28 and depressed first cover portion 31 is located within the inner circumference of raised first cover portion 29 of first top portion 28 Inner flange 18 extends downwardly from raised first cover portion 29 and includes threads 19 disposed within inner flange 18.
FIG. 15A is a top perspective view of cap 13 shown in FIG. 15. In this figure, second top portion 21 is secured to first top portion 28 forming compartment 42 between first top portion 28 and second top portion 21. Compartment 42 is in communication with aperture 41 enabling user 90 (not shown in FIG. 15A) to hold beverage container 10 by gripping through aperture 41 and grasping handle 47. One method of attachment of second top portion 21 to first top portion 28 is a snap fit. Other methods of attachment are well known to users of ordinary skill in the art. FIG. 15B is a bottom perspective view of cap 13 shown in FIG. 15. First top portion 28 of cap 13 is threadingly secured to neck portion 32 (not shown in FIG. 15B) via threads 19 within inner flange 18. When first top portion 28 of cap 13 is threadingly secured to neck portion 32, outer flange 39 becomes flush with outer surface 14 (not shown in FIG. 15B) of receptacle 11 (not shown in FIG. 15B).
FIG. 16 is a cross-sectional view of beverage container 10 shown in FIG. 13. FIG. 16A is an enlarged cross-sectional view of area 16A shown in FIG. 16, illustrating the interaction between plurality of ribs 22 of the spout and neck portion 32. Beverage container 10 comprises first seal 43 and second seal 44. First seal 43 prevents liquid flow between inner diameter surface 33 of neck portion 32 and outer surface 26 of spout 12. Plurality of ribs 22 is sealably engaged against inner diameter surface 33 of neck portion 32. Plurality of ribs 22 of spout 12 flexes upward and downward as plurality of ribs 22 engages inner diameter surface 33, which is smooth, creating first seal 43, similar to a cork fitting into a bottle. It should be appreciated that in a preferred embodiment, the spout is substantially cylindrical in shape; however, the shape and size of the spout may vary as necessary to conform to and sealably engage the inner diameter surface of the neck portion. Second seal 44 prevents liquid from flowing out of spout 12 when cap 13 is engaged. Cap 13 is operatively arranged to receive at least a portion of spout 12. First opening rim 35 is sealably engaged to first top portion 28 when cap 13 is secured to neck portion 32. First opening rim 35 of spout 12 matingly engages raised first cover portion 29 of first top portion 28. Depressed first cover portion 31 of first top portion 28 is forced downward slightly within first opening rim 35, which compresses first opening rim 35, forming second seal 44. At least one drainage aperture 45 is disposed within raised first cover portion 29 of first top portion 28. When first top portion 28 is forced downward compressing first opening rim 35, at least one drainage aperture 45 allows air to escape to create a stronger second seal 44. It should be appreciated that spout 12 is a single component. Unlike prior beverage containers, there is no separate valve to prevent liquid from flowing out of spout 12.
Thus, it is seen that the objects of the present invention are efficiently obtained, although modifications and changes to the invention should be readily apparent to those having ordinary skill in the art, which modifications are intended to be within the spirit and scope of the invention as claimed. It also is understood that the foregoing description is illustrative of the present invention and should not be considered as limiting. Therefore, other embodiments of the present invention are possible without departing from the spirit and scope of the present invention.
