at least one cup alignment indicator situated on the cup outer surface; and

a ring defining a substantially axisymmetric profile about a ring axis of rotation and comprising:

a ring upper surface sized and shaped to selectively engage the ring-engaging peripheral rim of the cup open lower surface;

a ring lower surface sized and shaped to selectively engage the lip that is formed around the dispensing end of the beverage container;

a radially-inward projecting trough formed about a substantial external periphery between the ring upper surface and ring lower surface to selectively engage the plurality of irregularly-spaced and radially inward-facing tabs of the cup lower surface;

at least one ring alignment indicator situated about the substantial external periphery between the ring upper surface and ring lower surface to provide indicia of whether or not the cup and ring are within registered alignment with one another; and

a pair of rows of teeth such that the teeth of each of the pair of rows extend radially inward from a respective one of the ring upper surface and ring lower surface, the teeth of at least one of the pair of rows being irregularly spaced from one another within their respective row,

wherein the ring and cup are cooperative with one another and the beverage container such that upon a registered snap-fit connection of the cup lower surface and the ring upper surface along their respective axes of rotation, the ring and cup form the assembly as a unitary whole that upon a snap-fit connection to the lip of the beverage container through the ring lower surface substantially inhibits access to the liquid that is situated within the beverage container.

2. The tamper-resistant lid assembly of claim 1 , wherein the at least one cup alignment indicator is radially aligned with a corresponding one of the plurality of irregularly-spaced and radially inward-facing tabs.

3. The tamper-resistant lid assembly of claim 1 , wherein at least one of the teeth within each row are not of the same in at least one of number, size and shape as the others within each row.

4. The tamper-resistant lid assembly of claim 1 , wherein the teeth of one of the pair of rows are not the same in at least one of number, size and shape as the teeth of the other of the pair of rows.

5. The tamper-resistant lid assembly of claim 1 , wherein the ring upper surface and ring lower surface each define a tapered connection to promote ease of the snap-fit connection with a respective one of the cup open lower surface and the lip that is formed around the dispensing end of the beverage container.

6. The tamper-resistant lid assembly of claim 1 , wherein the at least one ring alignment indicator is situated about the substantial external periphery between the ring upper surface and ring lower surface and projects radially outward from the substantial external periphery of the ring lower surface.

7. The tamper-resistant lid assembly of claim 1 , wherein the plurality of alignment indicators define a shape that projects radially-outward from the cup outer surface.

8. The tamper-resistant lid assembly of claim 1 , wherein at least one of the pair of rows of teeth define a castellated appearance on the ring.

9. The tamper-resistant lid assembly of claim 1 , wherein the cup closed upper surface further comprises an upward projecting central plateau configured to permit vertical stacking of a plurality of the beverage containers where at least a vertically lower one of the beverage containers has the tamper-resistant lid assembly secured thereto.

10. The tamper-resistant lid assembly of claim 1 , further comprising a seal disposed between the ring and the cup.

11. The tamper-resistant lid assembly of claim 1 , wherein the ring comprises enhanced deformability by virtue of a gap formed therein that extends from the ring upper surface to the ring lower surface and entirely therethrough.

12. The tamper-resistant lid assembly of claim 1 , wherein the at least one ring alignment indicator comprises a plurality of ring alignment indicator and the at least one cup alignment indicator comprises a plurality of cup alignment indicators.

13. A method of providing a tamper-resistant lid assembly for use in dispensing a premeasured amount of liquid from a beverage container, the method comprising:

arranging the tamper-resistant lid assembly to comprise:

a cup suitable for containing the premeasured amount of liquid, the cup sized and shaped to receive a premeasured amount of liquid therein, the cup comprising a cup closed upper surface, a cup open lower surface, a cup inner surface, a cup outer surface and at least one cup alignment indicator situated on the cup outer surface; and

a ring comprising a ring upper surface sized and shaped to selectively engage the cup open lower surface, a ring lower surface sized and shaped to selectively engage a lip that is formed around a dispensing end of the beverage container, a radially-inward projecting trough formed about a substantial external periphery between the ring upper surface and ring lower surface, at least one ring alignment indicator situated about the substantial external periphery between the ring upper surface and ring lower surface, and a pair of rows of teeth such that the teeth of each of the pair of rows extend radially inward from a respective one of the ring upper surface and ring lower surface, the teeth of at least one of the pair of rows being irregularly spaced from one another within their respective row;

configuring the at least one cup alignment indicator to be alignable with a corresponding one of the at least one ring alignment indicator to provide indicia of registered alignment of the cup and ring with one another;

configuring the ring and cup to be snap-fit secured to one another to through the radially-inward projecting trough upon the application of an axially compressive force between them once the indicia of registered alignment of the cup and ring with one another has been established; and

configuring the assembly that is formed by the snap-fit engagement between the ring and the cup to be placeable onto a lip of the beverage container such that upon such snap-fit engagement of the tamper-resistant lid assembly onto the lip of the beverage container by a user, a secure connection is formed therebetween that substantially inhibits access to the liquid that is situated within the beverage container.

14. The method of claim 13 , wherein the ring and the cup are configured to be snap-fit secured to one another prior to having the assembly be snap-fit secured to the beverage container.

15. The method of claim 13 , wherein the ring and the cup are configured to be snap-fit secured to one another after having the assembly be snap-fit secured to the beverage container.

16. The method of claim 13 , wherein the cup open lower surface defines a ring-engaging peripheral rim with a plurality of irregularly-spaced and radially inward-facing tabs extending therefrom while the ring upper surface defines a plurality of indents formed therein to accept the plurality of irregularly-spaced and radially inward-facing tabs upon the registered alignment of the cup and ring with one another.

17. The method of claim 13 , further comprising configuring the ring to be deformable through the inclusion of a gap formed therein.
