## Background
TECHNICAL FIELD
The present disclosure relates generally to a beverage container, and more specifically to a travel beverage container with a 360° pour spout.
BACKGROUND
Portable beverage containers, such as bottles, thermoses, and the like, are commonly used by people who want to temporarily store a beverage such as water, coffee, tea, or other liquid and then consume the beverage at a later time. Such portable beverage containers often lack guided or directed pour features and instead rely simply upon the upper rim or mouth of the container to direct or guide the flow of the beverage as the beverage is poured. As a result, it can be challenging for consumers to use such portable beverage containers, particularly in environments where controlled pouring is desirable.

DETAILED DESCRIPTION
While a beverage container according to the present disclosure is susceptible of embodiments in many different forms, there are shown in the drawings and will herein be described in detail preferred embodiments according to the disclosure with the understanding that the disclosure is to be considered as an exemplification of the principles of the claimed invention and thus is not intended to limit the broad aspects of the claimed invention to the specific embodiments illustrated.
A beverage container with a 360° pour spout assembly having open (or pouring) and closed (or sealed) orientations is disclosed herein. The 360° pour spout assembly disclosed herein provides a guided flow path that facilitates easy and controlled pouring (when in the open orientation) and prevents spills (when in the closed orientation). Because the 360° pour spout assembly disclosed herein provides a guided flow path that completely surrounds an opening in the container, a consumer can pick up and pour a beverage from the beverage container (when the pour spout assembly is in the open orientation) without needing to first arrange the beverage container in a specific orientation. In addition, thorough cleaning of the beverage container can be readily accomplished because the pour spout assembly is removably coupled to a beverage container body and an inner plug of the pour spout assembly is removably coupled to an outer plug of the pour spout assembly, such that the inner and outer plug components which cooperatively provide the guided flow path for pouring from the container are separable both from one another and from the container body and thus do not obstruct one another during cleaning.
Referring now to the figures, and specifically to FIGS. 1 and 2, there is shown a beverage container 10 generally comprising a container body 12, an outer cup assembly 14, and a pour spout assembly 16. The container body 12 defines an opening 13 providing access to an interior volume. The container body 12 generally has a longitudinal container body axis 15 extending through a center of the container body 12 in a longitudinal direction parallel to a length of the container body 12. As shown in FIG. 3, the container body 12 is a double walled container, but single walled containers are also contemplated. The double walls of container body 12 are useful in that they may include an insulative material, such as foam, or a vacuum between the walls, to improve the insulative performance of the beverage container 10. As illustrated, the container body 12 further includes external threads 18 at a spout end 20 which mate with corresponding internal threads (not shown) on an inner surface of the outer cup assembly 14 to removably couple the outer cup assembly 14 to the container body 12. The spout end 20 of the container body 12 also has internal threads 24 on an inner surface thereof that mate with corresponding external threads 26 on the pour spout assembly 16 to removably couple the pour spout assembly 16 to the container body 12 (see also FIGS. 3 and 8). The outer cup assembly 14 can be removably coupled to the container body 12 after the spout assembly 16 is removably coupled to the container body, i.e., the outer cup assembly 14 can be mounted over the spout assembly 16 and coupled to the container body once the spout assembly 16 has been coupled to the container body 12. The container body 12 may be manufactured from various materials including but not limited to metals, plastics, and combinations thereof. Stainless steel and aluminum are representative materials for manufacturing the container body 12.
As shown in FIGS. 4-9, the pour spout assembly 16 comprises an outer plug 30 and an inner plug 32. The pour spout assembly 16 has an annular pour spout 34 at a first end 36 of the outer plug 30 (the first end 36 generally corresponding to a top portion of the outer plug 30). In the illustrated embodiment, the annular pour spout 34 is provided by an outwardly flared inner wall section of the outer plug 30, with the outwardly flared inner wall section terminating at a rim 37 of the annular pour spout 34. The annular pour spout 34 can also be provided by a frustoconical or another suitably shaped annular wall section. When the pour spout assembly 16 is coupled to the container body 12, the annular pour spout 34 extends beyond a top surface of the opening 13 of the container body 12. The outer plug 30 and the inner plug 32 may be manufactured from various materials including but not limited to metals, plastics, and combinations thereof. Generally, the outer plug 30 and inner plug 32 are manufactured from thermoplastic materials such as polypropylene, polyethylene, and the like.
As shown in FIG. 5, the outer plug 30 is generally cylindrical. The outer plug 30 has external threads 26 toward a second end 38 thereof (the second end 38 generally corresponding to a bottom portion of the outer plug 30). As explained above, the external threads 26 assist in removably coupling the pour spout assembly 16 to the container body 12. The outer plug 30 also has an external rib 40 adjacent the first end 36 to assist in seating the pour spout assembly 16 on the container body 12. A central opening 35 of the outer plug 30 is generally defined by a rim 37 of the annular pour spout 34. In use, when the inner plug 32 is coupled to the outer plug 30, as shown in FIGS. 3, 8 and 9, the inner plug 32 is partially disposed in the central opening 35 of the outer plug 30. As shown in FIGS. 6 and 7, the inner surface of the outer plug 30 contains threads 42 which mate with corresponding threads 53 on the inner plug 32 to removably couple the inner plug 32 to the outer plug 30 (see also FIGS. 8 and 9). The threaded engagement between the inner plug 32 and the outer plug 30 allows the inner plug 32 to be vertically displaceable within the outer plug 30 along the longitudinal container body axis 15 and to thereby form a sealing lid for the beverage container body 12, capable of moving between open (or pouring) and closed (or sealed) orientations as described in further detail below. The threaded engagement also can translate torque applied to the inner plug 32 into a radial component capable of causing the inwardly radially deflectable retaining members 62 to radially deflect inwardly towards the center longitudinal axis 15.
Disposed on an inner surface of the outer plug 30 adjacent the second or bottom end 38 is a sealing wall 44 for sealing the inner plug 32 to the outer plug 30 when the pour spout assembly 16 is in the closed orientation. As best shown in FIG. 6, in the illustrated embodiment, the sealing wall 44 is provided by an inwardly flared inner sealing wall (i.e., flared inwardly towards the center longitudinal axis 15, when the spout assembly 16 is coupled to the container body 12). The sealing wall 44 can also be provided by a frustoconical or another suitably shaped sealing wall adjacent the second end 38 of the outer plug 30. As illustrated, a top tapered portion of the sealing wall 44 is distal to a bottom surface 39 of the second end 38 and a bottom inwardly flared portion of the sealing wall 44 is proximate the bottom surface 39 of the second end 38. An outer plug seal 46 (see FIG. 6) is seated in a seal seat 48 on an outer surface of the outer plug 30 proximate the bottom surface 39 of the outer plug 30 to assist in sealing the pour spout assembly 16 to the container body 12, when the pour spout assembly 16 is in the closed orientation. The outer plug seal 46 may be made of a resilient seal material.
As best shown in FIGS. 7 and 8, the inner plug 32 preferably comprises an inner plug top portion 50 and an inner plug body 52, which may be separate components that are connected together or they may be integral. The inner plug 32 also may have an insulative material 54, such as foam, in its inner core to provide additional insulative properties to the inner plug 32.
In one embodiment, the inner plug 32 has two seals, the first being an inner plug seal 56 disposed on an exterior surface of the inner plug 32 proximate a bottom surface 57 thereof. As described in further detail below, the inner plug seal 56 generally seals the area between the inner plug 32 and the outer plug 30 when the inner plug 32 is in the closed orientation, thereby preventing undesired fluid flow from the beverage container 10 (e.g., a beverage from inadvertently being inadvertently spilled, etc.). In an exemplary embodiment, the inner plug seal 56 is made of a resilient seal material.
The second seal of the inner plug 32 is a residual seal 60, generally residing at the joint between the top portion 50 and the body 52 of the inner plug 32. The residual seal 60 may be made of the same material as the inner plug body 52, or may be made of a resilient seal material (like the inner plug seal 56). In the embodiment shown in FIG. 7, the residual seal 60 is provided by an outwardly flared (i.e., away from the outer surface of the inner plug 32) annular seal. The residual seal 60 can also be provided by a frustoconical or another suitably shaped seal. As illustrated, a top flared portion of the residual seal 60 is proximate the top portion 50 of the inner plug 32 and a bottom tapered portion is distal to the top portion 50. Various resilient materials can be used to manufacture the outer plug seal 46, the inner plug seal 56, and the residual seal 60, including but not limited to silicones, rubbers, and thermoplastic elastomers.
In general, as best shown in FIG. 7, two or more sets of partial threads 53 are provided on an exterior surface of the inner plug 32. One or more channel sections 55 are also provided on the exterior surface of the inner plug 32, the one or more channel sections 55 being disposed between the sections carrying first and second sets of partial threading 53. The channel sections 55 are recessed at least relative to the sections of the inner plug 32 that carry the partial threading 53. The inner plug 32 also includes one or more retaining members 62 for preventing undesired/inadvertent separation of the inner plug 32 from the outer plug 30 and/or providing a positive indication to the consumer upon opening of the pour spout assembly 16 that the spout assembly 16 is in the fully open orientation that allows pouring.
As shown in FIGS. 4, 7 and 8, a plurality of retaining members 62 generally extend or protrude from the bottom of the inner plug body 52. In one embodiment, there are two retaining members or spring arms 62, each with stop walls 64 for retaining the inner plug 32 within the outer plug 30. As shown, retaining members 62 engage a stop rib 66 on an inner surface of the outer plug 30 when the inner plug 32 is moved to its fully open or pouring orientation. In one embodiment, with reference to FIGS. 6, 8 and 9, the stop rib 66 is provided by a circumferential stop rib on the inner surface of the outer plug 32 proximate a bottom surface thereof. The retaining members 62 are inwardly radially deflectable, for example, upon application of torque to the inner plug, as explained in further detail below.
In use, and with reference to FIGS. 8 and 9, the outer plug 30 and the inner plug 32 together provide the pour spout assembly 16 and form a sealing lid for the beverage container body 12 capable of moving between open (or pouring) and closed (or sealed) orientations. FIG. 8 illustrates the pour spot assembly 16 in the closed orientation and FIG. 9 illustrates the pour spot assembly 16 in the open orientation. In both orientations, both the inner plug 32 and the outer plug 30 of the pour spout assembly 16 are coupled to the container body 12. In both orientations, the inner plug 32 is rotationally received within the central opening 35 of the outer plug 30, such that the inner plug 32 is partially disposed in the central opening 35 of the outer plug 30. The outer plug 30 is twisted or rotated into the central opening 13 of the beverage container body 12 to couple the outer plug 30 to the beverage container body 12. After coupling the outer plug 30 to the container body 12, the inner plug 32 is already or can subsequently be rotated into and thereby partially disposed within and coupled to the outer plug 30.
As shown in FIG. 8, the outer plug seal 46 seals against an inner surface of the container body 12 when the pour spout assembly 16 is fully coupled to the container body 12 when the external threads 26 on the pour spout assembly 16 and the corresponding internal threads 24 of the container body 12 are mated such that further engagement is not possible. Again with reference to FIG. 8, the inner plug 32 is coupled to the outer plug 30 when the threads 42 on the inner surface of the outer plug 30 and corresponding sets of threads 53 on the outer surface of the inner plug 32 are mated. When the inner plug 32 is in the closed orientation, it is coupled to the outer plug 30 such that further engagement is not possible as is shown FIG. 8. In the closed orientation, the sealing wall 44 of the outer plug 30 is placed into sealing engagement with the inner plug seal 56 of the inner plug 32 such that a fluid from the container body 12 cannot flow into the plug assembly 16. In the closed orientation, the beverage container 10 is sealed or closed because the inner plug seal 56, which is located toward a bottom end 58 of the inner plug body 52, seals against the inwardly flared sealing wall 44 of the outer plug 30. As a result, the closed orientation can prevent liquid from being spilled or poured from the beverage container 10.
The residual seal 60 may also engage and seal against an inner surface of the outer plug 30 and thereby provide a secondary sealing interaction when the inner plug 32 is positioned in the closed orientation shown in FIG. 8. As a result, the residual seal 60 can prevent liquid from flowing out of the spout assembly 16 that may be beyond a first sealing interaction attributable to the inner plug seal 56 sealing against the inwardly flared sealing wall 44 of the outer plug 30. In addition, because the residual seal 60 can essentially trap air between the residual seal 60 and the inner plug seal 56, it can enhance the insulation of beverages contained in the beverage container 10.
To release liquid from the container 12 and place the pour spout assembly 16 in the open orientation shown in FIG. 9, the inner plug 32 of the beverage container shown in FIG. 8 is rotated, causing the inner plug 32 to be vertically displaced and move slightly upwardly (away from the container body 12) based on the threaded connection between the inner plug 32 and the outer plug 30. As a result of the inner plug 32 becoming vertically displaced, the inner plug seal 56 and the residual seal 60 are no longer in sealing engagement with the outer plug sealing wall 44 and the pour spout 34. As shown, the inner plug seal 56 disposed on the exterior surface of the inner plug 32 is separated from the outer plug sealing wall 44 to provide an annular ring flow path 61 between the inner wall of the outer plug 30 and the outer surface of the inner plug 32 that is in fluid communication with the interior volume of the beverage container 10. The annular ring entry flow path 61 permits fluid to enter and ultimately flow out of the pour spout assembly 16. In the open orientation, liquid can travel from the annular ring flow path 61 through a flow path (not shown) defined between the channel sections 55 of the inner plug 32 and an interior surface of the outer plug 30 and ultimately out a flow path 70 defined by the inner plug residual seal 60 and the annular pour spout 34. Liquid can then be poured out of the container body 12 by flowing between the outer wall of the inner plug 32 and the inner wall of the outer plug 30. Liquid can flow out the pour spout assembly 16 anywhere in the 360° pour area between the inner plug 32 and the outer plug 30. In cooperation, the outwardly flared pour spout 34 and the correspondingly contoured exterior surface of the residual seal 60 provide a fluid flow path allowing controlled and precise pouring from the beverage container 10 when the inner plug 32 is in the open orientation.
In the open orientation shown in FIG. 9, the inner plug 32 remains retained within the outer plug 30 of the pour spout assembly 16 because the stop walls 64 of the two retaining members 62 engage the stop rib 66 on the inner surface of the outer plug 30 when the inner plug 32 is rotated out of the outer plug 30. The engagement of stop walls 64 with the stop rib 66 creates a positive stop for the consumer upon positioning the pour spout assembly 16 in the fully open orientation. The positive stop provides consumers with feedback that the pour spout assembly 16 is in the fully open orientation (allowing pouring) because a tactile perception is apparent to the user upon rotating the inner plug 32 relative to the outer plug 30 and placing the stop walls 64 of the inner plug 32 retaining members 62 in contact or engagement with the stop rib 66 of the outer plug 60. The interaction between the stop walls 64 and the stop rib 66 can be overcome by causing the retaining members 62 to inwardly deflect and thereby become disengaged with the stop rib 66. In one embodiment, the stop walls 64 of retaining members 62 are configured to create a radial force causing deflection of the retaining members 62 upon application of an axial force. For example, an axial force can be translated into a radial component by interaction of mating surfaces provided on the stop wall 64 and the stop rib 66. In one exemplary embodiment, the stop walls 64 include an angled engagement surface 65 that mates with the stop rib 66 of the outer plug 30. The circumferential stop rib 66 can also include an angled or curved surface 67 at a point where the stop walls 64 and stop rib 66 are engaged after placing the pour spout assembly 16 in the fully open orientation. The retention arm angled engagement surface 65 and the stop rib angled or curved surface 67 generally have mating contoured angles between about 5 and about 20 degrees, for example about 10 degrees, relative to the center longitudinal container body axis 15.
Generally speaking, the interaction between the mating surfaces provided on the stop wall 64 and the stop rib 66 can be overcome when sufficient torque is applied to the inner plug 32. The threaded connection between the inner plug 32 and the outer plug 30 translates the torque applied to the inner plug 32 into an axial force and that axial force is further translated into a radial component by interaction of mating contoured surfaces provided on the stop wall 64 and the stop rib 66. The torque needed to overcome the interaction between the mating surfaces provided on the stop wall 64 and the stop rib 66 should be great enough to provide the consumer with a positive stop (i.e., a consumer applying a normal amount of torque to rotate the inner plug 32 out of the outer plug 30 would not overcome the positive stop without applying additional torque). On the other hand, the torque needed to overcome the interaction between the mating surfaces provided on the stop wall 64 and the stop rib 66 should not be difficult for some consumers to apply. Balancing these factors, the mating surfaces provided on the stop wall 64 and the stop rib 66 can be configured such that between about 0.5 newton meters and about 3 newton meters of torque is required to cause the retaining members 62 to inwardly deflect after engagement of the stop walls 64 with the stop rib 66 while providing the consumer with a positive stop. Once the interaction between the mating surfaces provided on the stop wall 64 and the stop rib 66 is overcome, the inner plug 32 can be completely removed from the outer plug 30 to facilitate cleaning of the inner plug 32 and the outer plug 30.
