Definitions
- This invention relates generally to a cup, and more particularly, but not by way of limitation, to a spill resistant transition cup.
- a sippy cup typically has a lid with a spout and a valve, through which the contents of the cup may be drunk. The valve helps prevent spills should the sippy cup tip over.
- the valve forces a user to suck on the spout, making the mechanism of drinking from a sippy cup similar to that of drinking from a baby bottle.
- the sucking process can also cause excruciating inner ear pain in children that are experiencing sinus congestion and/or infections.
- the valve is often made of silicone or a similar substance that must be separately washed. Washing a valve may be quite difficult due to its shape, and thus sippy cup valves are frequently less than ideally clean and often require regular replacement. Constantly sucking on sippy cup spouts may adversely affect the development of a child's teeth and mouth. Similarly, chewing on a sippy cup spout, as often happens, may not be healthy for the child.
- the use of a sippy cup may also discourage a child from learning how to properly drink from a regular cup, as the sippy cup may be held at any angle while drinking without spilling.
- the invention in general, in a first aspect, relates to a spill resistant cup comprising: a substantially hollow lower body with at top and a bottom, where the bottom of the lower body is closed and the top of the lower body is open; a substantially hollow upper body with a top and a bottom, where the top of the upper body is closed and the bottom of the upper body is open, the open bottom of the upper body corresponds to the open top of the lower body such that the upper body and the lower body together form a single vessel, and the top of the upper body has an opening, where the opening has a smaller diameter than the upper body; and an opening between the lower body and the upper body, where the opening has a smaller diameter than the lower body and the upper body.
- Fluid in the lower body may travel through the opening between the lower body and the upper body and into the upper body and then may travel through the opening in the top of the upper body when the cup is tipped sufficiently, but the fluid will not exit the cup significantly if the cup merely falls over.
- the upper body may have a diameter greater than the diameter of the lower body.
- the upper body and the lower body may be hollow.
- the cup may further comprise an arcuate lip projecting upward from the upper body such that the lip simulates a section of a rim of a drinking glass.
- the opening in the top of the upper body may be adjacent the lip.
- the cup may further comprise a second opening in the top of the upper body.
- the cup may further comprise a cover attached to the top of the upper body such that the cover may temporarily cover the opening in the top of the upper body.
- the cover may be slideably attached to the top of the upper body such that the cover may slide over the opening to cover it, or the cover may be a snap-through plug that snaps into the opening.
- the top of the upper body may be bowl-shaped.
- the cup may further comprise a lid that fits atop the bowl-shaped top of the upper body.
- the cup may further comprise an insert located adjacent the top of the lower body, where the opening between the lower body and the upper body is located in the insert.
- the insert may have a recess and the lower body may have a projection that fits within the recess such that the insert may be placed within the lower body only if the recess aligns with the projection.
- the insert may have a downwardly projecting trough attached thereto. The trough may angle backward away from the insert such that fluid in the lower body may travel up the trough only if the cup is tilted past 90°.
- the upper body may have a downwardly projecting trough attached thereto, where the trough extends from the top of the upper body to the insert, or to the opening between the upper body and the lower body if there is no insert, such that fluid may flow from the lower body, through the insert and/or the opening between the upper body and the lower body, along the trough, and out of the cup at the opening in the top of the upper body when the cup is tipped sufficiently.
- the lower body may be generally pyramid, upside-down pyramid, or prism shaped. If the lower body is generally pyramid shaped, the lower body may have a flat bottom, a plurality of triangular sides joined by a plurality of corners, and an apex, where the open top of the lower body is located at the apex.
- the upper body may have a downwardly projecting trough attached thereto, where the trough extends from the opening in the top of the upper body to the opening between the upper body and the lower body, and where the trough aligns with one of the corners of the lower body.
- the cup may further comprise a funnel-like structure extending from the opening in the top of the upper body to the trough, such that the funnel-like structure extends from the opening in the top of the upper body to the trough and the trough extends from the funnel-like structure to the opening in the bottom of the upper body, where the funnel-like structure has a wide end and a narrow end and where the narrow end is adjacent the trough.
- the upper body may comprise an upper portion and a lower portion, where the lower portion is attached to the base.
- the upper portion of the upper body may have a threaded lower edge and the lower portion of the upper body may have a threaded upper edge such that the upper portion attached to the lower portion by screwing the threaded lower edge to the threaded upper edge.

- the invention in general, in a first aspect, relates to a spill resistant cup with a bottom portion 1 and a top portion 2 , as seen in FIGS. 1 through 20 .
- the spill resistant cup may also have a lid 3 , as seen in FIGS. 1 through 3 .
- the bottom portion 1 may have two sections: a pyramid, shaped section 4 and a hemispherical section 5 , as seen in FIGS. 1 through 3 and 7 and in FIGS. 15 through 17 .
- the pyramid-shaped section 4 may have a different shape, such as an upside-down pyramid shape or a prism shape.
- the bottom portion 1 may not have pyramid-shaped section or a hemispherical section, as seen in FIGS.
- the top portion 2 may be generally hemispherical. If the bottom portion 1 has a hemispherical section 5 , the top portion 2 and the hemispherical section 5 of the bottom portion 1 , along with the lid 3 if there is a lid 3 , may generally form a sphere mounted atop the pyramid of the pyramid-shaped section 4 of the bottom portion 1 .
- the lid 3 may be shaped such that an opening 6 is provided between the lid 3 and the top potion 2 , seen in FIGS. 1 through 3 and 7 .
- the top portion 2 may have a lip 7 adjacent the opening 6 . If there is no lid 3 , the top portion 2 may house the opening 6 , as seen in FIGS. 10 through 17 .
- the top portion 2 and the hemispherical section 5 of the bottom portion 1 may generally form a three dimensional structure other than a sphere, such as an ellipsoid, a prolate spheroid, a character's head, or any other desired shape.
- the top portion 2 may not be hemispherical regardless of the presence of a hemispherical section 5 in the bottom portion 1 .
- each of the sections herein described as hemispherical may be not actually hemispherical but rather shaped like a portion of the three dimensional structure and/or other shape. For example, in FIGS.
- the top of the hemisphere is concave rather than convex.
- this structure is referenced as hemispherical throughout this application; however, this language is not limiting and the aspects of the invention described as such are equally applicable to any three dimensional structure, whether spherical/hemispherical or not.
- FIGS. 7 , 11 , 16 , and 17 show the bottom portion 1 without the top portion 2 attached.
- the bottom portion 1 may be hollow, such that it may hold fluid for drinking.
- the bottom portion 1 may have a triangular bottom 8 , as shown in the FIGS. 5 and 19 ; alternately, the bottom 8 may be any polygon, allowing the pyramid-shaped section 4 to have any desired number of sides. This would allow the spill resistant cup to settle quickly if tipped over.
- Another alternative is for the bottom 8 to be circular or otherwise at least partially curved, as shown in FIGS. 10 through 14 , such that the pyramid-shaped section 4 is cylindrical, conical, or has any other desired shape.
- the bottom 8 may ideally have at least one flat portion to allow the spill resistant cup to settle along that side if tipped over.
- the cup shown in FIGS. 10 through 14 has two flat portions, allowing the cup to settle on one of those two sides.
- Another alternative is for the bottom portion 1 to omit the hemispherical section, again as shown in FIGS. 10 through 14 . If so, the top portion 2 may similarly not be hemispherical.
- the pyramid-shaped section 4 may have a plurality of triangular sides 9 joined by corners 10 .
- the corners 10 may be rounded.
- the apex 11 of the pyramid-shaped section 4 may be open into the hemispherical section 5 , such that fluid may flow from the pyramid-shaped section 4 into the hemispherical section 5 and vice versa.
- a rim 12 may extend upward from the hemispherical section 5 .
- the hemispherical section 5 may be actually hemispherical, forming half of a sphere with the top portion 2 and lid 3 forming the other half of the sphere, or may be more or less than half of a sphere, with the top portion 2 and lid 3 forming the remainder of the sphere.
- the sphere formed by the hemispherical section 5 , the top portion 2 , and the lid 3 may have a diameter larger than the width of the pyramid-shaped section 4 .
- FIG. 8 shows the top portion 2 without the bottom portion 1 and lid 3 .
- the top portion 2 may have an exterior portion 13 shaped like a spherical section and an interior portion 14 shaped like a funnel, where the interior portion 14 is joined to the exterior portion 13 along their upper edges. Extending downward from the interior portion 14 may be a trough 15 .
- the trough 15 may extend through the hemispherical section 5 of the bottom section to the apex 11 of the pyramid-shaped section 4 of the bottom portion 1 , allowing fluid to flow out of the pyramid-shaped section 4 , along the trough 15 , along the interior portion 14 of the top portion 3 , and out of the spill resistant cup, when the cup is angled properly.
- the trough 15 may be attached to a separate middle portion 17 that fits between the bottom portion 1 and top portion 2 , as seen in FIGS. 11 and 14 .
- the trough 15 may angle backward from top to bottom, discouraging fluid from traveling up the trough 15 unless the cup is tipped past 90°.
- the middle portion 17 may have an opening 18 at the top of the trough 15 , allowing fluid to flow from the trough 15 into the top portion 2 when the cup is tipped sufficiently, and allowing fluid to flow from the top portion 2 into the bottom portion 1 when the cup is upright.
- the middle portion 17 may angle down inward toward the opening 18 to encourage fluid in the top portion 2 to enter the bottom portion 1 via the opening 18 , as seen in FIG. 14 .
- the middle portion 17 may have a notch 19 that fits onto a protrusion 20 on the inside of the bottom portion 1 to ensure proper alignment of the trough 15 , as seen in FIG. 11 .
- the top portion 2 may have an opening 6 adjacent the lip 7 , such that fluid entering the top portion 2 from the bottom portion 1 via the opening 18 in the middle portion 17 may exit the cup and be drunk by the user at the lip 7 , as from an ordinary cup.
- the top portion 2 may also have an opening 21 at its center to allow the cup to be filled easily without removing the top portion 2 from the bottom portion 1 .
- the trough 15 may be located within the top portion 2 rather than the bottom portion 1 , as seen in FIG. 20 .
- the trough 15 may extend from the opening 6 in the top portion 2 to an opening 23 in an insert 24 located within the bottom portion 1 .
- the insert 24 may be located where the pyramid-shaped section 4 meets the hemispherical section 5 .
- the cup may not have a trough, as shown in FIG. 21 .
- the cup may have an insert 25 that fits within the top of the bottom portion 1 and separates the bottom portion 1 from the top portion 2 .
- the insert 25 may have an opening 26 therein that allows fluid to flow past the insert 25 .
- the insert 25 may be thicker around its outer edges than around the opening, as shown FIG. 26 , such that both the top and bottom surfaces of the insert 25 angle inward, encouraging the flow of fluid through the opening 26 whether the cup is right side up (where fluid flows from the top portion 2 to the bottom portion 1 ) or upside down (where fluid flows from the bottom portion 1 to the top portion 2 ).
- the trough 15 may be integral to the wall of the cup. If so, the cup may have a bottle neck shape either in the bottom portion 1 or the top portion 2 . This cup design promotes the transfer of fluid past the insert 25 when such transfer is desirable.
- the opening 26 may be centered in the insert 25 , as shown, or may be located anywhere else along the insert 25 as desired.
- the top portion 2 may or may not have an opening 21 , as shown in FIG. 10 ; if it does, the opening 21 and the opening 26 may or may not be aligned.
- the opening 26 , as well as the opening 21 may be located anywhere along a shared center line. Both landing positions share a horizontal diameter. By misaligning the two holes along this diameter, spurting fluid from shaking or tipping misses the uppermost opening 21 and is contained in the top portion 2 . This applies to the embodiment shown in FIGS. 10 through 14 , as well.
- the cup may further comprise a cover 25 located such that it may slide over the opening 6 to further prevent spills when the cup is not in use or slide away from the opening 6 when the cup is in use, thus allowing fluid to flow out of the opening 6 to be drunk by the user.
- the cover 25 may be seen in FIGS. 15 through 18 .
- the bottom portion 1 may have a rim 12 extending upward and the top portion 2 may have a rim 16 extending downward, such that top portion 2 may attach to the bottom portion 1 along the rims 12 and 16 , respectively.
- the rims 12 and 16 may form a twist lock, such that the top portion 2 may be placed on the bottom portion 1 and twisted a short distance, causing the twist lock of rims 12 and 16 to engage, thus preventing the top portion 2 from being removed from the bottom portion 1 without untwisting.
- the rims 12 and 16 may be threaded such that they may be joined to each other by twisting.
- the rims 12 and 16 may have any other appropriate mechanism for attaching to one another such that the top portion 2 may be secured to the bottom portion 1 via the rims 12 and 16 .
- the spill resistant cup may have a gasket (not shown) located at the rims 12 and 16 to prevent leakage of fluid from the cup.
- the trough 15 may aligned such that, when the top portion 2 is fully secured to the bottom portion 1 with the rims 12 and 16 fully engaged with each other, the trough 15 lines up with one of the corners 10 of the pyramid-shaped section 4 of the bottom portion 1 .
- the fully assembled spill resistant cup tips over, it will settle along one of the sides 9 of the pyramid-shaped section 4 and any fluid that travels through the apex 11 from the pyramid-shaped section 4 into the hemispherical section 5 will not travel along the trough 15 , but rather into the body of the hemispherical section 5 itself.
- the fluid that has traveled into the hemispherical section 5 may return to the pyramid-shaped section 4 due to gravity and the geometry of the spill resistant cup.
- the top portion 2 may have a lip 7 .
- the lip 7 may extend from the top portion 2 and may be aligned with the trough 15 , such that the trough 15 is properly aligned for fluid transfer when the cup is used with the lip 7 at the user's mouth.
- the lip 7 may be generally shaped like a portion of the rim of a regular cup; thus, drinking from the spill resistant cup at the lip 7 replicates the feeling of drinking from a regular cup. This provides for an easier transition between using the spill resistant cup and using a regular cup.
- the lip 7 also provides an easy indicator of the proper alignment of the trough 15 .
- FIG. 9 shows the lid 3 .
- the lid 3 may be generally shaped like a spherical cap, such that the lid 3 may fit against the spherical section that is the exterior portion 13 of the top portion 2 to complete a hemisphere.
- the lid 3 may have an opening 6 , which may be located along one of its edges. When the lid 3 is in place on the spill resistant cup, fluid traveling from the pyramid-shaped section 4 along the trough 15 and along the interior portion 14 of the top portion 3 may exit the spill resistant cup via the opening 6 .
- the lid 3 may be placed on the spill resistant cup in such a way that the opening 6 is adjacent the lip 7 , allowing a user to drink from the cup at the lip 7 through the opening 6 .

Fluid in the lower body may travel through the opening between the lower body and the upper body and into the upper body and then may travel through the opening in the top of the upper body when the cup is tipped sufficiently, but the fluid will not exit the cup significantly if the cup merely falls over.
Description
- This application is based on and claims priority to U.S. Application No. 61/790,803 filed Mar. 15, 2013.
- 1. Field of the Invention
- This invention relates generally to a cup, and more particularly, but not by way of limitation, to a spill resistant transition cup.
- 2. Description of the Related Art
- The transition from baby bottles to drinking from a regular cup is difficult for children. The mechanism of drinking is different, and a cup must be held more carefully than a baby bottle to prevent spills. Many children stop drinking from baby bottles before they have the dexterity necessary to drink from a cup without spilling its contents. One common solution is the sippy cup. A sippy cup typically has a lid with a spout and a valve, through which the contents of the cup may be drunk. The valve helps prevent spills should the sippy cup tip over.
- The valve forces a user to suck on the spout, making the mechanism of drinking from a sippy cup similar to that of drinking from a baby bottle. The sucking process can also cause excruciating inner ear pain in children that are experiencing sinus congestion and/or infections. The valve is often made of silicone or a similar substance that must be separately washed. Washing a valve may be quite difficult due to its shape, and thus sippy cup valves are frequently less than ideally clean and often require regular replacement. Constantly sucking on sippy cup spouts may adversely affect the development of a child's teeth and mouth. Similarly, chewing on a sippy cup spout, as often happens, may not be healthy for the child. The use of a sippy cup may also discourage a child from learning how to properly drink from a regular cup, as the sippy cup may be held at any angle while drinking without spilling.
- Other populations would likewise benefit from a cup that is spill resistant, such as the elderly and those with dexterity issues.
- Based on the foregoing, it is desirable to provide an alternative to the sippy cup that provides a proper transition from a baby bottle to a standard drinking cup.
- It is further desirable to provide a cup that simulates the feeling of drinking from a regular cup while providing some spill resistance.
- It is further desirable to provide a spill resistant cup that does not have a valve.
- It is further desirable to provide a spill resistant cup that encourages children to learn how to hold a cup properly while drinking from it to prevent spills.
- In general, in a first aspect, the invention relates to a spill resistant cup comprising: a substantially hollow lower body with at top and a bottom, where the bottom of the lower body is closed and the top of the lower body is open; a substantially hollow upper body with a top and a bottom, where the top of the upper body is closed and the bottom of the upper body is open, the open bottom of the upper body corresponds to the open top of the lower body such that the upper body and the lower body together form a single vessel, and the top of the upper body has an opening, where the opening has a smaller diameter than the upper body; and an opening between the lower body and the upper body, where the opening has a smaller diameter than the lower body and the upper body. Fluid in the lower body may travel through the opening between the lower body and the upper body and into the upper body and then may travel through the opening in the top of the upper body when the cup is tipped sufficiently, but the fluid will not exit the cup significantly if the cup merely falls over.
- The upper body may have a diameter greater than the diameter of the lower body. The upper body and the lower body may be hollow. The cup may further comprise an arcuate lip projecting upward from the upper body such that the lip simulates a section of a rim of a drinking glass. The opening in the top of the upper body may be adjacent the lip. The cup may further comprise a second opening in the top of the upper body. The cup may further comprise a cover attached to the top of the upper body such that the cover may temporarily cover the opening in the top of the upper body. The cover may be slideably attached to the top of the upper body such that the cover may slide over the opening to cover it, or the cover may be a snap-through plug that snaps into the opening. The top of the upper body may be bowl-shaped. The cup may further comprise a lid that fits atop the bowl-shaped top of the upper body.
- The cup may further comprise an insert located adjacent the top of the lower body, where the opening between the lower body and the upper body is located in the insert. The insert may have a recess and the lower body may have a projection that fits within the recess such that the insert may be placed within the lower body only if the recess aligns with the projection. The insert may have a downwardly projecting trough attached thereto. The trough may angle backward away from the insert such that fluid in the lower body may travel up the trough only if the cup is tilted past 90°. Alternately, the upper body may have a downwardly projecting trough attached thereto, where the trough extends from the top of the upper body to the insert, or to the opening between the upper body and the lower body if there is no insert, such that fluid may flow from the lower body, through the insert and/or the opening between the upper body and the lower body, along the trough, and out of the cup at the opening in the top of the upper body when the cup is tipped sufficiently.
- The lower body may be generally pyramid, upside-down pyramid, or prism shaped. If the lower body is generally pyramid shaped, the lower body may have a flat bottom, a plurality of triangular sides joined by a plurality of corners, and an apex, where the open top of the lower body is located at the apex. The upper body may have a downwardly projecting trough attached thereto, where the trough extends from the opening in the top of the upper body to the opening between the upper body and the lower body, and where the trough aligns with one of the corners of the lower body. The cup may further comprise a funnel-like structure extending from the opening in the top of the upper body to the trough, such that the funnel-like structure extends from the opening in the top of the upper body to the trough and the trough extends from the funnel-like structure to the opening in the bottom of the upper body, where the funnel-like structure has a wide end and a narrow end and where the narrow end is adjacent the trough.
- The upper body may comprise an upper portion and a lower portion, where the lower portion is attached to the base. The upper portion of the upper body may have a threaded lower edge and the lower portion of the upper body may have a threaded upper edge such that the upper portion attached to the lower portion by screwing the threaded lower edge to the threaded upper edge.

It is understood that the devices and methods are not limited to the embodiments set forth herein for purposes of exemplification.
- In general, in a first aspect, the invention relates to a spill resistant cup with a
bottom portion 1 and atop portion 2, as seen inFIGS. 1 through 20 . The spill resistant cup may also have alid 3, as seen inFIGS. 1 through 3 . Thebottom portion 1 may have two sections: a pyramid, shapedsection 4 and ahemispherical section 5, as seen inFIGS. 1 through 3 and 7 and inFIGS. 15 through 17 . Alternately, the pyramid-shapedsection 4 may have a different shape, such as an upside-down pyramid shape or a prism shape. Alternately, thebottom portion 1 may not have pyramid-shaped section or a hemispherical section, as seen inFIGS. 10 through 14 , but rather may comprise a single section. Thetop portion 2, with thelid 3 in place if there is alid 3, may be generally hemispherical. If thebottom portion 1 has ahemispherical section 5, thetop portion 2 and thehemispherical section 5 of thebottom portion 1, along with thelid 3 if there is alid 3, may generally form a sphere mounted atop the pyramid of the pyramid-shapedsection 4 of thebottom portion 1. Thelid 3 may be shaped such that anopening 6 is provided between thelid 3 and thetop potion 2, seen inFIGS. 1 through 3 and 7. Thetop portion 2 may have alip 7 adjacent theopening 6. If there is nolid 3, thetop portion 2 may house theopening 6, as seen inFIGS. 10 through 17 . - Alternately, the
top portion 2 and thehemispherical section 5 of thebottom portion 1, and optionally thelid 3 as discussed above, may generally form a three dimensional structure other than a sphere, such as an ellipsoid, a prolate spheroid, a character's head, or any other desired shape. Likewise, thetop portion 2 may not be hemispherical regardless of the presence of ahemispherical section 5 in thebottom portion 1. In either case, each of the sections herein described as hemispherical may be not actually hemispherical but rather shaped like a portion of the three dimensional structure and/or other shape. For example, inFIGS. 10 through 20 , the top of the hemisphere is concave rather than convex. For the sake of simplicity, this structure is referenced as hemispherical throughout this application; however, this language is not limiting and the aspects of the invention described as such are equally applicable to any three dimensional structure, whether spherical/hemispherical or not. -
FIGS. 7 , 11, 16, and 17 show thebottom portion 1 without thetop portion 2 attached. Thebottom portion 1 may be hollow, such that it may hold fluid for drinking. Thebottom portion 1 may have atriangular bottom 8, as shown in theFIGS. 5 and 19 ; alternately, thebottom 8 may be any polygon, allowing the pyramid-shapedsection 4 to have any desired number of sides. This would allow the spill resistant cup to settle quickly if tipped over. Another alternative is for the bottom 8 to be circular or otherwise at least partially curved, as shown inFIGS. 10 through 14 , such that the pyramid-shapedsection 4 is cylindrical, conical, or has any other desired shape. If thebottom 8 is partially curved, it may ideally have at least one flat portion to allow the spill resistant cup to settle along that side if tipped over. For example, the cup shown inFIGS. 10 through 14 has two flat portions, allowing the cup to settle on one of those two sides. Another alternative is for thebottom portion 1 to omit the hemispherical section, again as shown inFIGS. 10 through 14 . If so, thetop portion 2 may similarly not be hemispherical. - If the
bottom 8 is a polygon, as inFIGS. 1 through 4 and 15 through 17, the pyramid-shapedsection 4 may have a plurality oftriangular sides 9 joined bycorners 10. Thecorners 10 may be rounded. The apex 11 of the pyramid-shapedsection 4 may be open into thehemispherical section 5, such that fluid may flow from the pyramid-shapedsection 4 into thehemispherical section 5 and vice versa. Arim 12 may extend upward from thehemispherical section 5. - The
hemispherical section 5 may be actually hemispherical, forming half of a sphere with thetop portion 2 andlid 3 forming the other half of the sphere, or may be more or less than half of a sphere, with thetop portion 2 andlid 3 forming the remainder of the sphere. The sphere formed by thehemispherical section 5, thetop portion 2, and thelid 3 may have a diameter larger than the width of the pyramid-shapedsection 4. Thus, when the spill resistant cup tips over, the top of the spill resistant cup may be inclined upward, discouraging spills. -
FIG. 8 shows thetop portion 2 without thebottom portion 1 andlid 3. As seen inFIG. 8 and the wireframe view inFIG. 4 , thetop portion 2 may have anexterior portion 13 shaped like a spherical section and aninterior portion 14 shaped like a funnel, where theinterior portion 14 is joined to theexterior portion 13 along their upper edges. Extending downward from theinterior portion 14 may be atrough 15. When the spill resistant cup is fully assembled, thetrough 15 may extend through thehemispherical section 5 of the bottom section to the apex 11 of the pyramid-shapedsection 4 of thebottom portion 1, allowing fluid to flow out of the pyramid-shapedsection 4, along thetrough 15, along theinterior portion 14 of thetop portion 3, and out of the spill resistant cup, when the cup is angled properly. - Alternately, the
trough 15 may be attached to a separatemiddle portion 17 that fits between thebottom portion 1 andtop portion 2, as seen inFIGS. 11 and 14 . Thetrough 15 may angle backward from top to bottom, discouraging fluid from traveling up thetrough 15 unless the cup is tipped past 90°. Themiddle portion 17 may have anopening 18 at the top of thetrough 15, allowing fluid to flow from thetrough 15 into thetop portion 2 when the cup is tipped sufficiently, and allowing fluid to flow from thetop portion 2 into thebottom portion 1 when the cup is upright. Themiddle portion 17 may angle down inward toward theopening 18 to encourage fluid in thetop portion 2 to enter thebottom portion 1 via theopening 18, as seen inFIG. 14 . Themiddle portion 17 may have anotch 19 that fits onto aprotrusion 20 on the inside of thebottom portion 1 to ensure proper alignment of thetrough 15, as seen inFIG. 11 . Thetop portion 2 may have anopening 6 adjacent thelip 7, such that fluid entering thetop portion 2 from thebottom portion 1 via theopening 18 in themiddle portion 17 may exit the cup and be drunk by the user at thelip 7, as from an ordinary cup. Thetop portion 2 may also have anopening 21 at its center to allow the cup to be filled easily without removing thetop portion 2 from thebottom portion 1. - Alternately, the
trough 15 may be located within thetop portion 2 rather than thebottom portion 1, as seen inFIG. 20 . Thetrough 15 may extend from theopening 6 in thetop portion 2 to anopening 23 in aninsert 24 located within thebottom portion 1. In particular, theinsert 24 may be located where the pyramid-shapedsection 4 meets thehemispherical section 5. - Alternately, the cup may not have a trough, as shown in
FIG. 21 . The cup may have aninsert 25 that fits within the top of thebottom portion 1 and separates thebottom portion 1 from thetop portion 2. Theinsert 25 may have anopening 26 therein that allows fluid to flow past theinsert 25. Theinsert 25 may be thicker around its outer edges than around the opening, as shownFIG. 26 , such that both the top and bottom surfaces of theinsert 25 angle inward, encouraging the flow of fluid through theopening 26 whether the cup is right side up (where fluid flows from thetop portion 2 to the bottom portion 1) or upside down (where fluid flows from thebottom portion 1 to the top portion 2). Optionally, thetrough 15 may be integral to the wall of the cup. If so, the cup may have a bottle neck shape either in thebottom portion 1 or thetop portion 2. This cup design promotes the transfer of fluid past theinsert 25 when such transfer is desirable. - The
opening 26 may be centered in theinsert 25, as shown, or may be located anywhere else along theinsert 25 as desired. Thetop portion 2 may or may not have anopening 21, as shown inFIG. 10 ; if it does, theopening 21 and theopening 26 may or may not be aligned. Theopening 26, as well as theopening 21, may be located anywhere along a shared center line. Both landing positions share a horizontal diameter. By misaligning the two holes along this diameter, spurting fluid from shaking or tipping misses theuppermost opening 21 and is contained in thetop portion 2. This applies to the embodiment shown inFIGS. 10 through 14 , as well. - In any of the embodiments, the cup may further comprise a
cover 25 located such that it may slide over theopening 6 to further prevent spills when the cup is not in use or slide away from theopening 6 when the cup is in use, thus allowing fluid to flow out of theopening 6 to be drunk by the user. Thecover 25 may be seen inFIGS. 15 through 18 . - The
bottom portion 1 may have arim 12 extending upward and thetop portion 2 may have arim 16 extending downward, such thattop portion 2 may attach to thebottom portion 1 along therims rims top portion 2 may be placed on thebottom portion 1 and twisted a short distance, causing the twist lock ofrims top portion 2 from being removed from thebottom portion 1 without untwisting. Alternately, therims rims top portion 2 may be secured to thebottom portion 1 via therims rims - As seen in
FIGS. 4 and 20 , thetrough 15 may aligned such that, when thetop portion 2 is fully secured to thebottom portion 1 with therims trough 15 lines up with one of thecorners 10 of the pyramid-shapedsection 4 of thebottom portion 1. Thus, if the fully assembled spill resistant cup tips over, it will settle along one of thesides 9 of the pyramid-shapedsection 4 and any fluid that travels through the apex 11 from the pyramid-shapedsection 4 into thehemispherical section 5 will not travel along thetrough 15, but rather into the body of thehemispherical section 5 itself. Upon righting the spill resistant cup, the fluid that has traveled into thehemispherical section 5 may return to the pyramid-shapedsection 4 due to gravity and the geometry of the spill resistant cup. - As noted above, the
top portion 2 may have alip 7. Thelip 7 may extend from thetop portion 2 and may be aligned with thetrough 15, such that thetrough 15 is properly aligned for fluid transfer when the cup is used with thelip 7 at the user's mouth. Thelip 7 may be generally shaped like a portion of the rim of a regular cup; thus, drinking from the spill resistant cup at thelip 7 replicates the feeling of drinking from a regular cup. This provides for an easier transition between using the spill resistant cup and using a regular cup. Thelip 7 also provides an easy indicator of the proper alignment of thetrough 15. -
FIG. 9 shows thelid 3. Thelid 3 may be generally shaped like a spherical cap, such that thelid 3 may fit against the spherical section that is theexterior portion 13 of thetop portion 2 to complete a hemisphere. As noted above, thelid 3 may have anopening 6, which may be located along one of its edges. When thelid 3 is in place on the spill resistant cup, fluid traveling from the pyramid-shapedsection 4 along thetrough 15 and along theinterior portion 14 of thetop portion 3 may exit the spill resistant cup via theopening 6. Thelid 3 may be placed on the spill resistant cup in such a way that theopening 6 is adjacent thelip 7, allowing a user to drink from the cup at thelip 7 through theopening 6. - Whereas, the devices and methods have been described in relation to the drawings and claims, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.
