Abstract

The present invention relates to a container ( 10 ) and a lid ( 12 ) for food products, wherein the lid produces audible and tactile feedback when the container is closed with the lid. The invention further relates to a method for forming a lid for engagement with a container for food products. According to a first aspect of the invention, a container with a lid comprises a body with a neck ( 14 ) surrounding an opening; at least one thread ( 20 ) on the neck; at least one thread ( 16 ) on the lid for engaging the at least one thread on the neck; and an engagement mechanism ( 18 ) on the lid to secure the lid to the body when the lid is in a fully engaged position. Audible and tactile feedback are produced when the lid moves into the fully engaged position.

First claim

The invention claimed is:

1. A container ( 10 ) with a lid ( 12 ) for food products comprising:
a body with a neck ( 14 ) surrounding an opening;
at least one thread ( 20 ) on the neck ( 14 );
an annular ring ( 22 ) on the neck ( 14 ) beneath the at least one thread ( 20 );
at least one thread ( 16 ) on the lid ( 12 ) for engaging the at least one thread ( 20 ) on the neck ( 14 ); and
an engagement mechanism ( 18 ) on the lid ( 12 ) to engage the annular ring ( 22 ) and secure the lid ( 12 ) to the neck ( 14 ) when the lid is in a fully engaged position, wherein audible and tactile feedback is produced when the lid ( 12 ) moves into the fully engaged position, wherein the container comprises polyethylene terephthalate and the lid comprising polypropylene,
wherein a subtle pop lasting at least 0.01 seconds is generated upon disengaging the lid ( 12 ) from the neck ( 14 ), and maximally 0.025 seconds, and wherein the subtle pop has a sound pressure level in the range of about 20 to 120 dB, and
wherein full engagement of the lid ( 12 ) with the neck ( 14 ) produces a snap sound, wherein the snap sound lasts at least 0.01 seconds, and maximally 0.025 seconds and wherein the sound pressure level of the snap is in the range of 20 to 120 dB,
wherein the engagement mechanism comprises a plurality of extended protrusions ( 18 ) at a lower portion of the lid positioned to snap over the annular ring ( 22 ) when the lid ( 12 ) moves into the fully engaged position.

2. The container with a lid of claim 1 , wherein the plurality of extended protrusions comprises a plurality of protrusions similar in length and circumferentially aligned at a lower portion of the lid ( 12 ) with an interruption between adjacent protrusions circumferentially around the lid.

3. The container with a lid of claim 1 , wherein the lid further comprises a recess ( 19 ) to receive the annular ring ( 22 ).

4. The container with a lid of claim 1 , wherein the audible and/or tactile feedback is generated by the engagement mechanism ( 18 ) moving over the annular ring ( 22 ) to engage the lid ( 12 ) with or disengage the lid ( 12 ) from the neck ( 14 ).

5. The container with a lid of claim 1 , wherein the at least one thread ( 20 ) on the neck ( 14 ) and/or the at least one thread ( 16 ) on the lid ( 12 ) are varied in thickness such that progressive torque is required to bring the lid ( 12 ) into the fully engaged position.

6. A method of forming a lid ( 12 ) for engagement with a container ( 10 ) for food products with at least one thread ( 20 ) and an annular ring ( 22 ) for food products, the method comprising:
forming a lid ( 12 ) comprising polypropylene with at least one thread ( 16 ); and
forming an engagement mechanism ( 18 ) comprising a plurality of extended protrusions ( 18 ) at a lower portion of an inner surface of the lid positioned to snap over the annular ring ( 22 ) when the lid ( 12 ) moves into the fully engaged position, and positioned such that audible and tactile feedback are produced from the engagement of the engagement mechanism ( 18 ) and the annular ring ( 22 ) when the lid ( 12 ) has moved into a fully engaged position with the container ( 10 ) comprising polyethylene terephthalate,
wherein a subtle pop lasting at least 0.01 seconds is generated upon disengaging the lid ( 12 ) from the neck ( 14 ), and maximally 0.025 seconds, and wherein the subtle pop has a sound pressure level in the range of about 20 to 120 dB, and wherein full engagement of the lid ( 12 ) with the neck ( 14 ) produces a snap sound, wherein the snap sound lasts at least 0.01 seconds, and maximally 0.025 seconds and wherein the sound pressure level of the snap is in the range of 20 to 120 dB.

7. The method of claim 6 , wherein the step of forming an engagement mechanism ( 18 ) on a lower portion of an inner surface of the lid ( 12 ) comprises: forming a plurality of protrusions circumferentially aligned around a lower portion of an inner surface of the lid.

8. The method of claim 6 , wherein the step of forming an engagement mechanism on a lower portion of an inner surface of the lid ( 12 ) comprises:
forming a recess ( 19 ) for receiving the annular ring ( 22 ) when the lid ( 12 ) moves into a fully engaged position with the container ( 10 ).
