## Abstract

A spillproof container assembly includes a container body and a lid body that is adapted to be fastened onto the container body by screwing. Both the container body and the lid body are advantageously provided with outwardly extending wing portions for enhancing the grippability of and properly orienting the container assembly for small children. The outwardly extending wing portions of the container body are aligned with the outwardly extending wing portions of the lid body. The lid body is provided with an acoustic waveguide, and sound generating structure is provided in communication with the acoustic waveguide for creating an audible feedback when the lid body has been tightened onto the container body to a predetermined relative position and tightness. The acoustic waveguide further functions as a viewing port that provides a visual feedback so that a user can visually verify the position of the lid body with respect to the container body. In addition, the wing portions of the lid body are designed to slightly interfere with and cam over respective upper platforms on the wing portions of the container body so that a user will be provided with a tactical feedback as a lid body is approaching an optimal amount of tightness with respect to the container body.

## Claims

### Claim 1

A container for a spillproof drinking assembly, comprising:
a container body having a first upper open end and a lower closed end;
a neck extending cylindrically outward and away from the first upper end of the container body, the neck including at least one threaded fastener on an outer surface of the neck to receive a cap,
wherein an outer surface of an upper end of the container body extends below the neck radially outward to define a shoulder;
a platform is disposed on the shoulder; and
a snap projection is disposed on the platform, wherein the snap projection extends upward, away from the platform to a predetermined height.

### Claim 2 (depends on 1)

A container for a spillproof drinking assembly according to claim 1, wherein the platform is disposed on top of an upper surface of the shoulder.

### Claim 3 (depends on 2)

A container for a spillproof drinking assembly according to claim 2, wherein the platform is substantially flat.

### Claim 4 (depends on 1)

A container for a spillproof drinking assembly according to claim 1, wherein the snap projection extends radial from a first end adjacent to an outer end of the shoulder.

### Claim 5 (depends on 4)

A container for a spillproof drinking assembly according to claim 4, wherein the snap projection extends radially inward to a second end adjacent to an inner end of the shoulder adjacent to the neck.

### Claim 6 (depends on 5)

A container for a spillproof drinking assembly according to claim 5, wherein a gap is provided between the second end of the snap projection and the neck.

### Claim 7 (depends on 1)

A container for a spillproof drinking assembly according to claim 1, wherein the snap projection comprises a snap ridge.
