Abstract

A non-spill collar and valve assembly having a collar and a seal. The collar comprising an internal wall having a support surface and one or more passage therethrough. The internal wall having a frustoconical shape with an open upper end that extends downward and inwardly into a closed lower end with a projection extending outward therefrom and a fastener assembly provided opposite the internal wall. The internal wall further comprises a support surface provided along an inner surface of the open upper end having one or more protrusions disposed radially adjacent to the support surface defining one or more channels. One or more passages are disposed through the internal wall to channel a fluid at a desired flow rate. The seal has a first surface substantially similar to a shape of the internal wall is also provided. The seal has a blind bore recess on a lower surface for receiving and securing the projection therein.

First claim

What is claimed:

1. A non-spill collar and valve assembly, comprising:
a collar comprising:
an internal wall having a frustoconical shape with an open upper end that extends downward and inwardly into a closed lower end with a projection extending outward therefrom and a fastener assembly provided opposite the internal wall, the internal wall further comprising:
a support surface provided along an inner surface of the open upper end having one or more protrusions disposed radially adjacent to the support surface defining one or more channels; and
one or more passages of a predetermined opening size disposed through the internal wall to channel a fluid at a desired flow rate; and

a seal having a first surface substantially similar to a shape of the internal wall, the seal having a blind bore recess on a lower surface for receiving and securing the projection therein.

2. The non-spill collar and valve assembly recited in claim 1 , wherein when more than one passage is present, the passages can have varying opening sizes.

3. The non-spill collar and valve assembly recited in claim 1 , wherein one or more protrusions are disposed on the support surface.

4. The non-spill collar and valve assembly recited in claim 1 , wherein the protrusions can have varying heights.

5. The non-spill collar and valve assembly recited in claim 1 , wherein one or more protrusions are disposed on the first surface of the seal adjacent to the support surface.

6. The non-spill collar and valve assembly recited in claim 1 , wherein the annular seal comprises one or more air valves adapted to communicate the transfer of air into the container.

7. The non-spill collar and valve assembly recited in claim 1 , wherein an air valve is disposed in at least one of the frustoconical surface of the annular seal or a center of the annular seal.

8. The non-spill collar and valve assembly recited in claim 1 , wherein the annular seal is biased to seal a peripheral edge against the support surface such that the channels are covered by the annular seal.

9. The non-spill collar and valve assembly recited in claim 8 , wherein when the peripheral edge of the annular seal is lifted off of the support surface in response to a suction force generated by a mouth of a user, at least one of the channels is partially exposed to form a fluid communication pathway between an interior of the peripheral edge and the support surface of the collar thereby allowing a fluid to flow through the channels into the mouth of the user.

10. The non-spill collar and valve assembly recited in claim 1 , wherein the internal frustoconical wall further comprising:
the closed lower wall expanding radially outward from a base of the projection to a first concentric edge;
an intermediate wall extending radially outward and away from the first concentric edge of the closed lower wall at a predetermined angle towards a second concentric edge at an upper end of the intermediate wall; and
a second radial ledge expanding radially outward from the upper end of the intermediate wall to the open circular upper end of the collar.

11. The non-spill collar and valve assembly recited in claim 1 , wherein an upper edge of the projection extends radially outward beyond a lower portion of an outer surface of a shaft of the projection to define a concentric shoulder, and wherein the annular seal comprises a concentric flange extending inwardly from a concentric edge of the blind bore recess, the concentric flange receiving and securing the concentric shoulder of the projection.

12. The non-spill collar and valve assembly recited in claim 1 , wherein the annular seal further comprises a raised portion on an upper surface and at the center having a radially outward extending flange to facilitate removing the annular seal from the collar.

13. A non-spill collar and valve assembly, comprising:
a collar comprising:
an internal wall having a frustoconical shape with an open upper end that extends downward and inwardly into a closed lower end with a projection extending outward therefrom and a fastener assembly provided opposite the internal wall, the internal wall further comprising:
a support surface along an inner surface of the open upper end;
one or more protrusions of a predetermined height disposed radially adjacent to the support surface defining a channel through which a fluid is dispensed at a predetermined flow rate, wherein the predetermined height of the protrusions corresponds to an amount of suction to lift the seal away from the support surface; and
one or more passages disposed through the internal wall that channels the fluid; and

a seal having a first surface substantially similar to a shape of the internal wall, the seal having a blind bore recess on a lower surface for receiving and securing the projection.

14. The non-spill collar and valve assembly recited in claim 13 , wherein when more than one protrusion is present, more than one predetermined height can be provided by the protrusions.

15. The non-spill collar and valve assembly recited in claim 13 , wherein the passages have varying opening sizes.

16. A non-spill collar and valve assembly, comprising:
a collar comprising:
an internal wall having a frustoconical shape with an open upper end that extends downward and inwardly into a closed lower end with a projection extending outward therefrom and a fastener assembly provided opposite the internal wall, the internal wall further comprising:
a support surface along an inner surface of the open upper end; and one or more passages disposed through the internal wall to channel a fluid; and

a seal having a first surface substantially similar to a shape of the internal wall, the seal having a blind bore recess on a lower surface for receiving and securing the projection, the seal further comprising one or more protrusions disposed radially adjacent to the support surface defining a channel.

17. The non-spill collar and valve assembly recited in claim 16 , wherein when more than one passage is present, more than one predetermined opening size can be provided.

18. The non-spill collar and valve assembly recited in claim 16 , wherein when more than one protrusion is present, more than one predetermined height can be provided.

19. The non-spill collar and valve assembly recited in claim 16 , wherein the annular seal is biased to seal a peripheral edge against the support surface such that the channels are covered by the annular seal.

20. The non-spill collar and valve assembly recited in claim 16 , wherein when the peripheral edge of the annular seal is lifted off of the support surface in response to a suction force generated by a mouth of a user, at least one of the channels is partially exposed to form a fluid communication pathway between an interior of the peripheral edge and the support surface of the collar thereby allowing a fluid to flow through the channels into the mouth of the user.
