FLUID FUNNELLING DEVICE

FIELD OF THE INVENTION

The present invention relates to a device for funneling fluid from a first opening to a second opening.

BACKGROUND OF THE INVENTION

It is common for drinking vessels to have a cover, top, or lid forming a mouthpiece or spout through which the user can drink. For example, drinking cups for children, the elderly or infirm, sports bottles, and water bottles may utilize a mouthpiece through which the user can drink. Funneling fluid contained in the drinking vessel through an outlet that is smaller than an opening of the drinking vessel may be helpful to direct the fluid and mitigate spillage.

However, in order to be comfortable and ergonomic for drinking by a user, the funnel may reduce in depth between upper and lower surfaces, effectively tapering to a rim, or rim portion, from which to drink. Commonly, this may be a continuous rim or a defined region of rim, or a rim portion as at the extreme end of a spout.

However, tapering may reduce an internal dimension of the mouthpiece containing the funnel, and it may become difficult to access and thoroughly clean interior sides of the funnel or mouthpiece, particularly at an extreme end. Due to the difficulty in cleaning inside the mouthpiece, dirt and bacteria may build up over time and create a health hazard. This may be exacerbated in products where the mouthpiece is constructed of multiple components.

In order to address this problem, it may be tempting to increase the internal dimensions of the mouthpiece so as to provide easier access. However, health experts warn that spouts that are used for sucking and sit on top of the tongue, may obstruct the natural oral action of the palate, which may cause physical and speech problems as a child develops. This may be exacerbated the more the spout depth is increased.

Speech and language pathologists recommend that children are not encouraged to suck from a spout but instead are encouraged to drink from the rim of a cup, where the rim is held to the lips, and is not placed on top of the tongue. Parents, however, may be reluctant to give young infants an open cup because of the potential for spillage.

A funneling device that facilitates easy access for cleaning in addition to providing controlled drinking from a cup rim may therefore be desirable.

The present disclosure has been devised to mitigate at least some of the above-mentioned problems.

SUMMARY OF THE INVENTION

In accordance with a first aspect of the present disclosure, there is provided a fluid funneling device for facilitating fluid transmission from a first opening, the fluid funneling device comprising: a funnel outer wall surrounding a funnel cavity; an upper wall connected to an upper rim of the outer wall via a connecting portion; and a fluid outlet for funneling fluid; wherein said connecting portion is configured to bias the upper wall in a first position, wherein said upper wall extends into the funnel cavity in the first position, whereby an interior side of the upper wall and an interior side of the outer wall define a funneling portion of the funnel cavity; and wherein the fluid outlet is configured to provide access to the funneling portion. The term “upper wall” may be understood as a portion or surface that is connected to the outer wall via a connecting portion.

The term “funneling portion” may be understood as a portion of the fluid funneling device that reduces in dimension from a first end to a second end.

In use, the first opening may be proximate an opening of a fluid container, such that the fluid funneling device facilitates transmission from the opening of the fluid container, through the funneling portion and out the fluid outlet. The fluid funneling device may therefore advantageously provide a means for funneling fluids from the fluid container to the mouth of a user.

In some embodiments, the fluid outlet is a dispensing valve configured to control a flow of fluid from the funneling portion. Advantageously, the dispensing valve may minimize fluid escaping the fluid outlet in certain orientations.

In some embodiments, the dispensing valve is a flap valve. In some embodiments, the dispensing valve is a slit valve. However, it will be appreciated that the dispensing valve may be any suitable valve for controlling the flow of fluid from the funneling portion.

The connecting portion and/or the upper wall are resiliently flexible. The connecting portion comprises a substantially flexible material. A “flexible material” may be understood as a material suitable for or capable of being bended or manipulated without breaking. In some embodiments, the flexible material is a silicone rubber material. In alternative embodiments, the flexible material is a thermoplastic elastomer. However, it will be understood that the flexible material may be any suitable flexible material. In this way, the connecting portion may be manipulated and/or moved without breaking and the fluid funneling device may be more resilient to damage.

The upper wall comprises a substantially flexible material. A “flexible material” may be understood as a material suitable for or capable of being bended or manipulated without breaking. In some embodiments, the flexible material is a silicone rubber material. In alternative embodiments, the flexible material is a thermoplastic elastomer. However, it will be understood that the flexible material may be any suitable flexible material. In this way, the upper wall may be manipulated and/or moved without breaking and the fluid funneling device may be more resilient to damage.

In some embodiments, the outer wall comprises a substantially rigid material. The term “substantially rigid” may be a material that is more resilient to being bended or manipulated than the connecting portion and/or the upper wall. In some embodiments, the outer wall is a plastic. In alternative embodiments, the outer wall is a metal. However, it will be understood that the substantially rigid material may be any suitable rigid material. In this way, the outer wall may provide a sturdy formation that is resilient to manipulation. Advantageously, the fluid funneling device may adhere to a desired shape more effectively.

In alternative embodiments, the outer wall comprises a substantially flexible material. A “flexible material” may be understood as a material suitable for or capable of being bended or manipulated without breaking. In some embodiments, the flexible material is a silicone rubber material. In alternative embodiments, the flexible material is a thermoplastic elastomer. However, it will be understood that the flexible material may be any suitable flexible material. In this way, the outer wall may be manipulated and/or moved without breaking and the fluid funneling device may be more resilient to damage. Furthermore, in this way, the cleaning configuration may be achieved when a threshold pressure is applied to the interior side of the outer wall, for example when a user applies a generally upwards force to the interior side of the outer wall at the same time as an opposing force to the upper wall. In this case, the fluid funneling device may evert such that in this cleaning configuration, the interior side of the upper wall and the interior side of the outer wall face outwardly.

The upper wall is configured to move between the inwards first position and an outwards second position when a pressure exceeding a threshold is applied to the upper wall. In the second position, the upper wall extends outwardly from the outer wall. In this way, the upper wall may be moved between the first position and the second position depending on a pressure applied to the upper wall. The first position may be a position suitable for drinking, since the funneling portion is defined in this position. The second position may be suitable for cleaning because an internal dimension of the fluid funneling device is enlarged. Advantageously, the enlarged internal dimension may make it easier to clean the fluid funneling device. In some embodiments, the first position is an axially inwards first position, and the second position is an axially outwards second position. However, it will be appreciated that the first and second position can alternate along any axis.

In some embodiments, the connecting portion comprises a mechanical hinge configured to facilitate rotation of the upper surface about an axis of rotation. In these embodiments, the upper wall may be resiliently flexible, and the outer wall may be substantially flexible or substantially rigid. The term ‘resiliently flexible’ may be understood as being biased in a first state or position but being able to deviate from this shape in response to a force and returning to the first state after the deviation.

The outer wall comprises a substantially annular axial cross section; and, in the first position, the upper wall comprises a substantially parabolic transverse cross section. In this way, the outer wall may be suitably shaped for use with generic fluid containers. Furthermore, the parabolic transverse cross section may provide a funneling portion that reduces in dimension from a first end to a second end. Advantageously, the fluid funneling device may provide a suitable funnel.

The funneling portion extends at least partially around a circumference of the interior side of the upper wall. In some embodiments, the funneling portion extends fully around the circumference of the interior side of the upper wall. In alternative embodiments, the funneling portion extends partially around the circumference of the interior side of the upper wall. That is, at some points around the circumference of the interior side of the upper wall, the interior side of the upper wall may meet the interior side of the outer wall, such that no funneling portion is present.

A connecting portion thickness is lower than an upper wall thickness and an outer wall thickness. Advantageously, the upper wall may more easily alternate between the first position and the second position. It will be appreciated that the thickness of the connecting portion may match the upper wall thickness and the outer wall thickness.

In the first position, the upper wall extends at least partially into the funnel cavity. In some embodiments, the upper wall extends fully into the funnel cavity such that a vertex of the upper wall occupies the first opening. In alternative embodiments, the upper wall extends partially into the funnel cavity such that there is a separation between the vertex of the upper wall and the first opening.

In some embodiments, the fluid funneling device further comprises a pressure releasing member. The pressure releasing member is configured to reduce an internal pressure of the funnel cavity. The pressure releasing member may be an opening positioned on an outer surface of the upper wall. However, the pressure releasing member may be situated anywhere on the device suitable for reducing an internal pressure of the funnel cavity.

In some embodiments, the fluid funneling device further comprises a wall separating member configured to prevent contact between the interior side of the upper wall and the interior side of the outer wall. In this way, a consistent flow of fluid may be provided via the funneling portion. The wall separating member may be a protrusion.

The fluid funneling device further comprises a base portion extending from a lower rim of the outer wall, whereby the base portion is arranged to have a feature for attachment. In particular, the feature for attachment may be a feature for facilitating attachment of the fluid funneling device to a fluid container. In this way, the fluid funneling device may be attached and removed from a fluid container, such as a bottle.

In some embodiments, the components are integrally molded from an appropriate material. In this way, the fluid funneling device is more easily manufactured. For embodiments where the components are integrally molded from a flexible material, the outer wall comprises an outer wall thickness that is greater than a thickness of the connecting portion, and greater than a thickness of the upper wall, such that the outer wall is resilient to deformation. In alternative embodiments, some or all of the components are separately manufactured and suitably joined.

In some embodiments, the outer wall comprises a varying height from a lower face to a higher face. This variation may result in an angular upper wall. The variation may be linear or non-linear. In these embodiments, it is preferable that the fluid outlet is located proximate the higher face. In these embodiments, the outer wall and upper wall may function as a spout.

Advantageously, a user may more easily receive fluids because an angular upper wall may provide more space for the nose of the user while drinking, which may be particularly desirable when a circumference of the outer wall is small. Also, the angular upper wall may provide a greater visibility of a mouth while in use which may be advantageous in certain circumstances, such as when an infant is learning to drink from a cup.

In some embodiments, the fluid funneling device comprises a baffle component having a baffle fluid outlet configured to control a fluid flow rate. The baffle component may be attachable to the outer wall at any location suitable between the opening and the fluid outlet. The baffle component may advantageously provide a means for further controlling a flow rate of a fluid from the first opening to the fluid funneling portion.

The baffle component comprises more than one baffle fluid outlet, each facilitating a different fluid flow rate. In this way, the baffle component may provide a means for further controlling a flow rate.

The fluid funneling device further comprises an interior valve arranged to control a fluid flow through the baffle disc. Advantageously, fluid flow through the interior valve may be prevented during non-drinking periods, such as during transit of the device.

In some embodiments, the interior valve is a flexible flap protruding from an interior side of the outer wall.

In some embodiments, the interior valve is a slit cut flexible surface of an inner portion of the baffle disc, configured to alternate between an open configuration and a closed configuration.

In some embodiments, a wall of the fluid funneling device comprises an outlet closing component configured to prevent fluid from flowing through the baffle fluid outlet when the upper wall is in the first position. The outlet closing component may be a closing projection located adjacent the baffle fluid outlet. The outlet closing component may comprise an actuation means. The actuation means may be located at any suitable location of the fluid funneling device. In some embodiments, the outlet closing component is a level located away from the fluid funneling portion. In some embodiments, the baffle fluid outlet is located substantially centrally on the baffle component. However, the baffle fluid outlet may be located at any point on a surface of the baffle component.

In some embodiments, the fluid funneling device further comprises a second fluid outlet arranged to facilitate a second flow rate different to a first flow-rate of the fluid outlet.

In accordance with a second aspect of the present disclosure, there is provided a method of manufacturing a fluid funneling device.

In accordance with a third aspect of the present disclosure, there is provided a fluid container comprising: an outer surface surrounding a fluid containing chamber; a neck comprising a first opening for providing access to the fluid containing chamber; and a fluid funneling device for facilitating fluid transmission from the first opening, the fluid funneling device comprising: a funnel outer wall surrounding a funnel cavity; an upper wall connected to an upper rim of the outer wall via a connecting portion; and a fluid outlet for funneling fluid; wherein the connecting portion is configured to bias the upper wall in a first position, wherein the upper wall extends into the funnel cavity in the first position, whereby an interior side of the upper wall and an interior side of the outer wall define a funneling portion of the funnel cavity; and wherein the fluid outlet is configured to provide access to the funneling portion, whereby the funneling portion facilitates fluid transmission from the first opening. The fluid funneling device may be the fluid funneling device of the first aspect of the present disclosure. Accordingly, the third aspect of the present disclosure may provide a fluid container incorporating the fluid funneling device.

It will be appreciated that any features described herein as being suitable for incorporation into one or more aspects or embodiments of the present disclosure are intended to be generalizable across any and all aspects and embodiments of the present disclosure. Other aspects of the present disclosure can be understood by those skilled in the art in light of the description, the claims, and the drawings of the present disclosure.

DETAILED DESCRIPTION FOR CARRYING OUT THE INVENTION

FIG. 1A shows a perspective view of a fluid funneling device 100 for facilitating fluid transmission from a first opening (not shown). FIG. 1B shows a transverse cross section of the fluid funneling device 100 of FIG. 1A.

The fluid funneling device 100 comprises a funnel outer wall 102; an upper wall 104; a connecting portion 106; a fluid outlet 108; a funneling portion 122; and a base portion 126. In this example, the fluid funneling device 100 is integrally molded from an appropriate material, such as a silicone rubber material, so as to form a one-piece construction. In alternative embodiments, some or all of the components are separately manufactured and suitably joined.

The outer wall 102 surrounds or bounds a funnel cavity 110, as shown in FIG. 1B. In this embodiment, the outer wall 102 comprises a substantially annular axial cross section. The outer wall 102 comprises a vertical section 112 having a uniform radius at a lower end of the outer wall 102, and a section of varying radius at an upper end of the outer wall 102, such that the outer wall 102 comprises a curved surface 114. The outer wall 102 may be substantially rigid, although may alternatively be substantially flexible.

The upper wall 104 is connected to an upper rim 116 of the outer wall 102 via the connecting portion 106. The upper wall 104 extends continuously inwards from the upper rim 116 via the connecting portion 106. In the embodiment depicted in FIGS. 1A and 1B, the connecting portion 106 is configured to bias the upper wall 104 in a first position. In particular, the connecting portion 106 is a portion extending transversely inwards from the rim 116 of the outer wall 102. Due to the curved portion 114, the connecting portion 106 causes the upper wall 104 to extend along a transverse axis relative to the axis of the outer wall 102. In the first position, the upper wall 104 extends at least partially into the funnel cavity 110. In particular, the upper wall 104 comprises a substantially dish or inverted dome shape, such that the upper wall 104 comprises a substantially parabolic transverse cross section. The upper wall 104 is substantially flexible so as to allow the upper wall 104 to flex in response to a pressure differential.

The fluid outlet 108 is defined by an opening in the connecting portion 106 between the outer wall 102 and the upper wall 104. Accordingly, the connecting portion 106 continuously connects the upper wall 104 to the outer wall 102, except for the opening defining the fluid outlet 108. The connecting portion 106 may be rigid, or substantially flexible.

The fluid outlet 108 is depicted as a singular slit in the opening portion 106. However, the fluid outlet 108, and all other fluid outlets in subsequent embodiments, may be of any suitable form for facilitating fluid communication, such as the openings 604 of the fluid funneling device 600 depicted in FIG. 6.

The fluid outlet 108 functions as a flap valve in that it controls the flow of the fluid from the funneling portion 122 out of the fluid outlet 108. In particular, when the fluid funneling device 100 is oriented upright, the fluid outlet 108 may be in a substantially closed position such that fluid is prevented from passing. When the fluid funneling device 100 is oriented substantially horizontally, or in a manner such that fluid flows from the funneling portion 122 to the fluid outlet 108, the fluid outlet 108 still prevents fluid from passing. However, in the presence of a negative pressure, a separation between the upper portion 104 and the upper rim 116 increases such that fluid flows out of the funneling portion 122 via the fluid outlet 108.

The fluid outlet 108 is configured to provide access to the funneling portion 122, wherein an interior side 118 of the upper wall 104 and an interior side 120 of the outer wall 102 define the funneling portion 122 of the funnel cavity 110. In particular, the interior sides 118, 120 cooperate to form a portion that is suitably shaped to funnel fluids to the fluid outlet 108. Due to the shape of the upper wall 104, the funneling portion 122 reduces in size towards the fluid outlet 108, such that the funneling portion 122 acts as a guide for guiding fluid to the fluid outlet 108.

In this embodiment, the funneling portion 122 extends fully around the circumference of the interior side 120 of outer wall 102. However, it will be appreciated that, in some embodiments, the interior side 120 of the outer wall 102 and the interior side 118 of the upper wall 104 may be adjacent so as to limit fluid flow, such that the funneling portion 122 extends only partially around the circumference of the interior side 120 of the outer wall 102.

The base portion 126 extends from a lower rim of the outer wall 102. The base portion 126 is arranged to have a feature for attachment. In some embodiments, an inner portion of the base portion 126 comprises a threaded portion configured to cooperate with a corresponding threaded portion of a fluid container (not shown). In use, the fluid funneling device 100 may be attached to the fluid container via the corresponding threaded portions, such that the first opening is shared with an opening of the fluid container. It will be appreciated that any attachment means may be used to attach the fluid funneling device 100 to the fluid container, such as those discussed with reference to the following embodiments.

FIG. 2A shows a perspective, cross-sectional view of an alternative fluid funneling device 200 for facilitating fluid transmission from a first opening (not shown) suitable for alternating between a first configuration and a second configuration. In particular, the fluid funneling device 200 is suitable for alternating between a drinking configuration and a cleaning configuration. FIG. 2A shows a perspective, cross-sectional view of the fluid funneling device 200 in the drinking configuration. FIG. 2B shows a perspective, cross-sectional view of the fluid funneling device 200 in the cleaning configuration.

The fluid funneling device 200 comprises a funnel outer wall 202; an upper wall 204; a connecting portion 206; a fluid outlet 208; and a funneling portion 222. In this example, the fluid funneling device 100 is integrally molded from an appropriate material, such as a silicone rubber material, so as to form a one-piece construction. In alternative embodiments, some or all of the components are separately manufactured and suitably joined.

The outer wall 202 surrounds or bounds a funnel cavity 210. In this embodiment, the outer wall 202 comprises a substantially annular axial cross section. The outer wall 202 comprises a vertical section 212 having a uniform radius proximate a lower end of the outer wall 102, and a section of varying radius proximate an upper end of the outer wall 202, such that the outer wall 202 comprises a curved surface 214. The outer wall 102 may be substantially rigid, or substantially flexible.

The upper wall 204 is connected to an upper rim 216 of the outer wall 204 via the connecting portion 206. The upper wall 204 extends continuously inwards from the upper rim 216 via the connecting portion 206. In the embodiment depicted in FIGS. 2A and 2B, the connecting portion 206 is resiliently flexible such that it biases the upper wall 104 in the first position. In particular, the connecting portion 206 is a portion of the materially that is folded or bent in on itself such that the upper wall 204 extends along a transverse axis relative to the axis of the outer wall 202. In the first position, the upper wall 204 extends at least partially into the funnel cavity 210. In particular, the upper wall 204 comprises a substantially dish or inverted dome shape, such that the upper wall 210 comprises a substantially parabolic transverse cross section. The upper wall 204 is substantially flexible.

The fluid outlet 208 is configured to provide access to the funneling portion 222, wherein an interior side 218 of the upper wall 204 and an interior side 220 of the outer wall 202 define the funneling portion 222 of the funnel cavity 210. In particular, the interior sides 218, 220 cooperate to form a portion that is suitably shaped to funnel fluids to the fluid outlet 208. Due to the shape of the upper wall 204, the funneling portion 222 reduces in size towards the fluid outlet 208, such that the funneling portion 222 acts as a guide for guiding fluid to the fluid outlet 208.

The connecting portion 206 functions as a living hinge in that it is made from the same material as the outer wall 202 and the upper wall 204. The connecting portion 206 is resiliently flexible, such that it biases the upper wall 204 in the first position (i.e. the drinking configuration), even during use when a fluid exerts a pressure against the interior side 218 of the upper wall 204. In this embodiment, the connecting portion 206 is substantially flexible. In some embodiments, the connecting portion 206 is a mechanical hinge configured to facilitate rotation of the upper surface about an axis of rotation. In these embodiments, the upper wall may be resiliently flexible.

The fluid outlet 208 is defined by an opening in the connecting portion 206 between the outer wall 202 and the upper wall 204. Accordingly, the connecting portion 206 continuously connects the upper wall 204 to the outer wall 202, except for the opening defining the fluid outlet 208.

In this embodiment, the fluid outlet 208 is always open. In some embodiments, the fluid outlet 208 comprises a slit cut valve. However, it will be appreciated that the fluid outlet 208 may comprise any suitable valve.

The connecting portion 206 is also configured to allow the fluid funneling device 200 to change to the second position (i.e. the cleaning configuration). In particular, when a threshold pressure is applied to the interior side 218 of the upper wall 204, for example when a user applies a generally upwards force to the interior side 218. In response to this pressure, the upper wall 204 shifts axially outwardly by rolling the connecting portion 206 over upon itself until the upper wall 204 is fully outwardly extended as shown in FIG. 2D.

FIG. 2C shows a front view of a fluid funneling device 270, substantially similar to the fluid funneling device 200. However, the fluid funneling device 270 comprises a substantially vertical outer wall.

The cleaning configuration may be achieved for the fluid funneling device 270 when a threshold pressure is applied to an interior side 290 of the outer wall 272, for example when a user applies a generally upwards force to the interior side 290 of the outer wall 272 at the same time as an opposing force to the upper wall 274. In this case, the fluid funneling device 270 everts such that in this cleaning configuration, an interior side 294 of the upper wall 204 and the interior side 290 of the outer wall 272 face outwardly.

The fluid funneling devices 200, 270 comprise a base portion substantially similar to the base portion 126 of the fluid funneling device 100, such that the fluid funneling devices 200, 270 are attachable to a fluid container.

FIG. 3A shows a front perspective view of an alternative fluid funneling device 300. FIG. 3B shows a transverse cross-sectional view of the fluid funneling device 300.

The fluid funneling device 300 comprises a funnel outer wall 302; an upper wall 304; a connecting portion 308; a fluid outlet 306; and a funneling portion 322; and a base portion 324. In this example, the fluid funneling device 300 is integrally molded from an appropriate material, such as a silicone rubber material, so as to form a one-piece construction.

The outer wall 302 surrounds or bounds a funnel cavity 310, as shown in FIG. 3B. The outer wall 302 comprises a substantially annular axial cross section. The outer wall 302 comprises a lower face 302A having a first height, and a higher face 302B having a second height. The second height is greater than the first height, wherein the height is a separation from the base portion 324 to a distal end of the outer wall. The outer wall 302 comprises a varying height from the lower face 302A to the higher face 302B. In the embodiment depicted, the height variation is non-linear. However, it will be appreciated that the height variation may be linear.

The upper wall 304 is connected to an upper rim 316 of the outer wall 302 via the connecting portion 308. The upper wall 304 extends continuously inwards from the upper rim 316 via the connecting portion 308. In the embodiment depicted in FIGS. 3A and 3B, the connecting portion is configured to bias the upper wall 304 in a first position. In particular, the connecting portion 308 is a portion extending transversely inwards from the rim 316 of the outer wall 302. In the first position, the upper wall 304 extends at least partially into the funnel cavity 310. In particular, the upper wall 304 comprises a substantially dish or inverted dome shape, such that the upper wall 304 comprises a substantially parabolic transverse cross section, wherein a vertex of the parabolic cross section is into the funnel cavity 310. Due to the varying height between the lower face 302A and the higher face 302B of the outer wall 302, the upper wall 304 similarly comprises one end at a lower height than the opposing end.

The fluid outlet 306 is substantially similar to any of the aforementioned embodiments, and is located proximate the higher face 302B.

The base portion 324 extends from a lower rim of the outer wall 302. The base portion 324 is arranged to have a feature for attachment. In this embodiment, the feature for attachment is a snap fit attachment comprising a snap-fit assembly 328. The snap-fit assembly 328 comprises an annular axial cross-section and a substantially U-shaped transverse cross section having a space 329. The snap-fit assembly 328 is configured to cooperate with a corresponding transverse lip 330 of a fluid container 332. The transverse lip 330 is similarly annular in axial cross-section and flange is configured to occupy the space 329 of the snap-fit assembly 328.

In use, the fluid funneling device 300 may be attached to the fluid container 332 the corresponding threaded portions, by applying an inward force to the snap fit assembly 328 or the outer wall 302 such that the snap fit assembly 328 is moved inwards from a first position to a second position. The transverse lip 330 is aligned with the snap-fit assembly space 329, and the inward force is released. Following release of the inward force, the snap-fit assembly 328 moves outwards back to the first position, whereby the transverse lip 330 occupies the snap-fit assembly space 329. Similarly, the fluid funneling device 300 may be removed for cleaning or otherwise by applying an inward force to the snap fit assembly 328 or the outer wall 302 such that the snap fit assembly 328 is moved inwards from the first position to the second position. The transverse lip 330 is moved to be unaligned with the snap-fit assembly space 329, and the inward force is released. Following release of the inward force, the snap-fit assembly 328 moves outwards back to the first position, whereby the transverse lip 330 no longer occupies the snap-fit assembly space 329.

Turning now to FIG. 4A, there is shown a transverse cross-sectional view of a fluid funneling device 400. The fluid funneling device 400 is depicted as being substantially similar to the fluid funneling device 300, although it will be appreciated that it may be of similar construction to any of the aforementioned fluid funneling devices. However, the fluid funneling device 400 differs in that an interior surface 403 of the outer wall 402 and an interior surface 407 of the upper wall 405 are connected or adjacent around a circumference of the outer wall 402, except for an opening which defines the fluid funneling portion 411. Alternatively, the fluid funneling portion 411 may be an interior channel in the outer wall 402.

The fluid funneling device 400 comprises a base portion 426 extending from a lower rim of an outer wall 402. The base portion 426 is arranged to have a feature for attachment. In this embodiment, the feature for attachment is a collar 428 and a flange 432 extending transverse from the lower rim of the outer wall 402. The collar comprises a first opening 434A defined by an annular rim 436 of the collar 428 and a screw thread 430 on an interior side of the collar 428. The screw thread 430 comprises a projection extending outwardly from the interior side of the collar 428. The screw thread 430 is configured to be received by a corresponding vessel screw thread (not shown).

To attach the collar 428 to the outer wall 402, an inward force is applied to the outer wall 402, such that the flange 432 moves inwards. The collar 428 is aligned with the outer wall 402, whereby when the inward force is released, the flange 432 moves outwards to its initial position such that an upper surface of the flange 432 is adjacent or in contact with a lower surface of the rim 436. In this configuration, axial movement of flange 432 is restricted by an upper portion 438 of the screw thread projection and the rim 436.

The fluid funneling device 400 further comprises a baffle component 440 attachable to the outer wall 402, of which a top-down view is depicted in FIG. 4B. The baffle component comprises a continuous inner portion 442 and an annular flange 444. As shown in FIG. 4A the inner portion 442 and the flange 444 are separated by an axial annular step 446. The baffle component 440 comprises a fluid outlet 448, such as a first fluid outlet 448A; a second fluid outlet 448B; and a third fluid outlet 448C. Each fluid outlet 448 is configured to provide a different fluid flow rate. In the present embodiment, the different fluid flow rate is achieved by a differing size of fluid outlet. In particular, the first fluid outlet 448A comprises a first fluid flow rate defined by a first outlet size, the second fluid outlet 448B comprises a second fluid flow rate defined by a second outlet size; and the third fluid outlet 448C comprises a third fluid flow-rate defined by a third outlet size, wherein the first outlet size is greater than the second outlet size, and the second outlet size is greater than the third outlet size.

The baffle component 440 is attachable to the collar 428 in a similar manner to the outer wall 402. However, it is noted that the baffle component 440 may be attached to the collar 428 before the outer wall 402 is attached to the collar 428. In particular, an inward force is applied to the step 446, such that the flange 444 moves inwards. The collar 428 is aligned with the step 446, whereby when the inward force is released, the flange 444 moves outwards to its initial position such that an upper surface of the flange 444 is adjacent or in contact with a lower surface of the rim 436. In this configuration, axial movement of flange 444 is restricted by the upper portion 438 of the screw thread projection and the rim 436. To choose a desired flow-rate, the outer wall 402 is attached to the collar 428 such that the fluid funneling portion is aligned with the desired fluid outlet 448. When the outer wall 402 is attached to the collar 428, the baffle component 440 may further restrict axial movement of the flange 432 by occupying a gap between the upper portion 438 of the screw thread and the rim 436.

The baffle component 440 may alternatively be attached after the outer wall 402 is attached to the collar 428, by inserting the baffle component 440 through a second opening 434B, opposing the first opening 434A. In particular, the baffle component 440 may be pushed up through the second opening 434B, towards the first opening 434A, until the flange 444 meets the flange 432. If the outer wall 402 is not yet attached, the baffle component 440 may be pushed up the second opening 434B until the flange 444 passes the upper portion 438 of the screw thread 430, or the flange 444 meets the lower surface of the rim 436.

It will be appreciated that, in some embodiments, the baffle component 440 is present without the collar 428.

The whole assembly of the fluid funneling device 400 may be attached to a fluid container via the screw thread of the collar 428. In alternative embodiments, the collar 428 functions as a snap fit, or other attachment means. In these alternative embodiments, the collar 428 comprises an annular protrusion similar to the upper portion 438 of the screw thread 430, such that the outer wall 402 and the baffle component 440 can be restrained in a gap between the annular protrusion and the rim 436.

FIG. 4C shows a transverse cross-sectional view of a fluid funneling device 450 comprising the baffle component 440.

The fluid funneling device 450 is of substantially similar construction to the fluid funneling device 400, but further comprises an interior valve 452 configured to control a fluid flow from the baffle component through the fluid outlet 448. The valve is a flexible flap 452 protruding from an inner surface 454 of an outer wall 456 of the fluid funneling device 450. The flap 452 is configured to cover the fluid outlet 448 until the fluid funneling device 450 is in a manner that causes fluid to flow from a fluid container to the baffle disc, and through the fluid outlet 448 in the presence of a pressure difference, for example in response to a user sucking the fluid outlet of the upper wall 402.

FIG. 4D shows transverse cross-sectional view of a fluid funneling device 460 comprising an alternative baffle component 461 having an alternative valve 462. In this version, the valve 462 is a slit cut flexible surface 462 of an inner portion 464 of the baffle component 461, such as a dome, configured to alternate between an open configuration and a closed configuration. In this embodiment, the fluid outlet 468 is a slit 468 of the flexible surface 462. Alternatively, the slit 468 may be a plurality of slits, for example in a cross-cut configuration. In the presence of a negative pressure, for example in response to a user sucking the fluid outlet of the upper surface, the valve inverts or distorts to the open configuration. This distortion or inversion opens the outlet 468, and fluid flows from an attached vessel, through the outlet 468 into the funneling portion. The flexible portion allows air back into the vessel by returning to the closed position, thereby equalizing the pressure after the fluid has been released through the upper wall outlet.

FIG. 4E shows a transverse cross-sectional view of a fluid funneling device 470 comprising an alternative baffle component 480. The baffle component 480 is similar to the baffle component 440, but comprises a fluid outlet 482 located at a central point of an inner portion 484 of the baffle component 480.

The fluid funneling device 470 is substantially similar to the fluid funneling device 200 in that an outer wall 472 of the fluid funneling device 400 comprises a uniform height. However, the fluid funneling device 470 further comprises an outlet closing component 474 protruding from an interior side 476 of an upper wall 478 of the fluid funneling device 470. The outlet closing component 474 is configured to prevent fluid from flowing through the fluid outlet 482 when the upper wall 478 is in the first position. In the present example, the outlet closing component 474 is an annular stud 474 comprising an axial abutment 474A; a flexible annular flange 474B extending transverse from the abutment 474A; and an outer stud portion 474C protruding from an upper surface of the upper wall 478. An outlet radius of the outlet 482 is greater than an abutment radius of the abutment 474A. A flange radius of the flange 474B is greater than the outlet radius.

In use, the stud 474 can be pushed through the outlet 482 by applying a downward force to an outer surface of the upper wall 478. Since the flange 474B is flexible, it deviates from its default position such that it can fit through the outlet 482, and snaps back to the default position after it has passed through the outlet 482. The stud 474 can be removed from the outlet by applying an upward force via the outer stud portion 474C, for example by a user pulling the outer stud portion 474C.

FIG. 5A shows a fluid container 500 in a closed configuration. FIG. 5B shows a perspective view of the fluid container 500 in an open configuration. FIG. 5C shows a fluid funneling device 506. FIG. 5D shows a lid collar 510.

The fluid container 500 comprises an outer surface 502 surrounding a fluid containing chamber; a neck 504 comprising a first opening for providing access to the fluid containing chamber; and the fluid funneling device 506 for facilitating fluid transmission from the first opening. The fluid containing chamber is configured to store a fluid, such as water, for drinking by a user.

The fluid funneling device 506 may be substantially similar to any of the aforementioned fluid devices, although it is substantially similar to the fluid funneling device 300 in that an outer wall 512 comprises a varying height. The fluid funneling device 506 comprises a base portion 508 extending from a lower rim of the outer wall 512, whereby the base portion 508 is arranged to have a feature for attachment, henceforth a “device attaching portion”. In the present example, the device attaching portion is an annular device rim 514.

The lid collar 510 comprises an annular collar rim 516 protruding from a body portion 528. In use, the fluid funneling device 506 is attachable to the lid collar 510 by applying a force radially outward to an inner surface of the outer wall 512 of the fluid funneling device 506 such that the device rim 514 moves outwards. The device rim 514 is then aligned with the collar rim 516 and the force is released, such that the device rim 514 returns to the first position, whereby an inner portion of the device rim 514 contacts an outer surface of the collar rim 516. The rims are dimensioned such that the device rim 514 is stretched during contact, such that a frictional force is present which retains the fluid funneling device 506 to the lid collar 510.

The lid collar 510 further comprises a collar base portion 518 extending from a lower rim of the body portion 528, the collar base portion 518 comprising a collar attaching portion. In the present example, the collar attaching portion is a collar screw thread comprising an indentation (not shown) extending inwardly into an exterior surface of the collar base portion 518.

The neck 504 comprises a container attaching portion (not shown) configured to interact with the collar attaching portion of the lid collar 510, the container attaching portion and the device attaching portion facilitating attachment of the lid collar 510 to the fluid container 500.

The container attaching portion is a container screw thread comprising a projection (not shown) extending outwardly from an inner portion of the neck 504, such that the lid collar 510 can be screw threaded on the neck 504. The indentation of the collar screw thread is sized to receive the projection of the container screw thread when the lid collar 510 is screw threaded on the neck 504.

The lid collar 510 comprises a lid 520 shown in FIGS. 5A and 5B attached to the body portion 528 via a hinge 522 located on an upper surface of the body portion 528. The lid collar 510 further comprises a retaining mechanism 524. The retaining mechanism 524 comprises a body component 524A and a lid component 524B. The body component 524A is located on an opposing side of the body portion 528 to the hinge 522. The lid component 524B is located on an opposing side of the lid 520 to the hinge 522. The lid 520 is configured to alternate between an open position and a closed position via the hinge 522. The closed position is achieved by the body component 524A of the retaining mechanism 524 receiving the lid component 524B of the retaining mechanism lid retaining member 524 and preventing further rotation by the hinge 522. The retaining mechanism 524 is releasable.

The lid 520 comprises a lid outer wall 530 and a lid upper wall 532 extending inwardly from an upper rim of the lid upper wall 532. The lid outer wall 530 comprises an annular axial cross section and is configured to surround the outer wall 512 of the fluid funneling device 506 when the fluid funneling device 506 is attached to the lid collar 510. The lid upper wall 532 extending continuously inwards such that it covers an upper wall 534 of the fluid funneling device 506.

The lid 520 further comprises a protrusion 536 extending inwardly from an interior side of the lid upper wall 532. The protrusion 536 is positioned such that when the lid 520 is moved from the open position to the closed position and the fluid funneling device 506 is in the cleaning configuration, the protrusion 536 applies a downward force, thereby causing the fluid funneling device 506 to switch to the drinking configuration. Additionally, the protrusion 536 ensures that the fluid funneling device 506 remains in the drinking configuration when the lid covers it. This is particularly useful if the fluid container 500 contains a significant weight or volume of fluid, which might otherwise compromise stability of the upper wall.

When the fluid funneling device of the above embodiments is in the cleaning configuration, access to the interior sides of the fluid funneling device may be easier and in turn, it may be easier to clean the interior sides. Due to the improved ease of access and cleaning, the fluid outlet of the fluid funneling device may be of a smaller size than conventional funnels or spouts that rely on a larger size to facilitate the cleaning of internal surfaces. An advantage of having a smaller sized fluid outlet is that it may be more comfortable for a user to use or drink from, and may provider a closer experience to drinking from a rim of a conventional cup, whilst helping to prevent spills. This may advantageously assist in the prevention of physical or speech problems in a child that may otherwise occur if a device is used having a funnel that is configured for sucking or sits on top of the child's tongue.

In the above embodiments, it can be seen that the fluid outlets of the respective fluid funneling devices are of smaller dimension than the first opening. Accordingly, the fluid funneling systems provide a means for funneling fluids for a larger dimension source (the first opening) to a smaller dimension fluid outlet.

The above embodiments have been described with respect to fluid funneling devices having a single fluid outlet. However, the fluid funneling devices may comprise a second fluid outlet. For example, as can be seen in FIG. 6, a fluid funneling device 600 comprises a first fluid outlet 608; and a second fluid outlet 624. In the example of FIG. 6, the second fluid outlet 624 is positioned at an opposing circumferential position of an upper rim 616 to the fluid outlet 608. In this embodiment, a fluid flow-rate may be controlled by selecting which fluid outlet to drink from. In particular, the first fluid outlet 608 comprises more holes than the second fluid outlet 624, such that the flow-rate of the first fluid outlet 608 is greater than a flow-rate of the second fluid outlet. Alternatively, if the fluid outlet 608 was a singular slit, such as the fluid outlet 108, the fluid outlet 608 could extend a first circumferential distance around the upper rim 616 and the second fluid outlet 624 extends a second circumferential distance around the upper rim 616. The first circumferential distance is different to the second circumferential distance, such that a first flow rate of the fluid out of the fluid outlet 608 is different to a second flow rate of the fluid out of the second fluid outlet 624. In this way, a user may select different flow rates for the fluid based on the fluid outlet that the fluid flows from. It will be appreciated that the second fluid outlet 624 may be located at any suitable location proximate the upper rim 616. Furthermore, it will be appreciated that further fluid outlets may be present such that more than two fluid flow rates are achievable. Any of the aforementioned embodiments may incorporate a second fluid outlet.

FIG. 7A shows an alternative fluid funneling device 700 in the first position (i.e., the drinking position). FIG. 7B shows the fluid funneling device 700 in the second position (i.e. the cleaning position).

The fluid funneling device 700 comprises a funnel outer wall 702 surrounding a funnel cavity 704. The fluid funneling device 700 further comprises an upper wall 706 connected to an upper rim 708 of the outer wall 702 via a connecting portion 710. The fluid funneling device 700 further comprises a fluid outlet 712 for funneling fluid. The connecting portion 710 is configured to bias the upper wall 706 in the first position shown in FIG. 7A, wherein said upper wall 706 extends into the funnel cavity 704 in the first position, whereby an interior side 714 of the upper wall 706 and an interior side 716 of the outer wall 702 define a funneling portion 718 of the funnel cavity 704. The fluid outlet 712 is configured to provide access to the funneling portion 718.

In this embodiment, the outer wall 702 comprises a spout portion 720 having an angular side. In the first position, the upper wall 706 extends into the funnel cavity 704 defined by the spout portion 720 of the outer wall 702. However, it will be appreciated that the dimensions may differ and that the upper wall 706 may also extend into the larger portion of the funnel cavity 704.

The fluid funneling device 700 may be alternated between the first position and the second position in response to a force, similar to those of the preceding embodiments.

It will be appreciated that the fluid funneling device 700 may comprise various components and aspects of any of the preceding embodiments.

Furthermore, the above embodiments have been described with respect to fluid funneling devices having outer walls having a substantially annular axial cross-section. However, in some embodiments, the outer wall comprises any suitably shaped axial cross-section. 3 For example, the outer wall may comprise a substantially ovular axial cross-section. In these embodiments, the funneling device may be particularly suitable for use with a first opening having a similarly ovular axial cross-section. In each of the above embodiments, the fluid outlet may be a dispensing valve configured to control a flow of fluid from the funneling portion. For example, the dispensing valve may be the flap valve as shown on the fluid funneling device 100. However, it will be appreciated that the dispensing valve may be any suitable valve for controlling the flow of fluid from the funneling portion.

Each of the above embodiments may further comprise a wall separating member. For example, with reference to FIG. 1B, the fluid funneling device 100 comprises a wall separating member 124 configured to prevent contact between the interior side 118 of the upper wall and the interior side 120 of the outer wall. The wall separating member 124 in this instance is a protrusion 124, which extends at least partially around the circumference of the interior side 118 of the upper wall 104 proximate the fluid outlet 108. It will be appreciated that the protrusion 124 may alternatively extend at least partially around the circumference of the interior side 120 of the outer wall 102 proximate the fluid outlet 108. The wall separating member 124, or protrusion 124, provides a means for preventing contact proximate the fluid outlet 108 of the interior side 118 of the upper wall 104 and the interior side 120 of the outer wall 102. In this way, the wall separating member 124 may prevent a seal from forming when the wall sides contact each other. In alternative embodiments, the wall separating member 124 comprises at least one axially extending protrusion, which extends at least partially from the fluid outlet 108 to the first opening. In this way, contact between the interior sides 118, 120 may be prevented across the entire axially extending protrusion. Further wall separating member 124 configurations may be envisaged, such as ribs, raised pimples, or textures surfaces.
