Manual portion control feeder
View Patent ↗An improved manual portion control feeder includes a food delivery mechanism that is in communication with a food reservoir and which, when actuated, dispenses a predetermined amount of food from the reservoir into another vessel. Advantageously, the feeding apparatus further includes a feedback mechanism which, responsive to an actuation of the food delivery mechanism, provides at least one of an acoustic indication and a tactile indication that is representative of the dispensing of a predetermined quantity of food by the food delivery mechanism. The acoustic and/or tactile indication enables the feeding apparatus to remain disposed on, for example, a floor and alerts the user that a predetermined amount of food has been dispensed from the reservoir since the acoustic and/or tactile indications are detectable with relative ease. This enables an animal to be provided a predetermined amount of food with minimal attention being required of the user.
1. A feeding apparatus configured to dispense food, comprising:
a housing comprising a reservoir structured to have an amount of food situated therein and another vessel;
a rotatable food delivery mechanism situated on the housing and configured to be in communication with the reservoir, the food delivery mechanism having a manual input element structured to dispense food from the reservoir into the another vessel when actuated; and
a feedback mechanism situated on at least one of the housing and the food delivery mechanism configured to respond to a manual actuation of the food delivery mechanism to provide at least one of an acoustic indication and a tactile indication that is representative of the dispensing of a predetermined quantity of food by the food delivery mechanism,
the feedback mechanism comprising a first structure situated on the food delivery mechanism and a second structure situated on the housing, the first and second structures being configured to engage one another upon rotation of the food delivery mechanism to generate the at least one of the acoustic indication and the tactile indication
one of the first structure and the second structure comprising a protruding tab that is configured to be elastically deflected and elastically returned toward an undeflected free state upon rotation of the food delivery mechanism to generate the at least one of the acoustic indication and the tactile indication,
the other of the first structure and the second structure further comprising a deflection element and an abutment element, the tab being deflected and engaged with the deflection element during a first portion of an actuation of the food delivery mechanism, the tab being elastically returned toward the undeflected free state and engaged with the abutment element to generate the at least one of the acoustic indication and the tactile indication during a second portion of the actuation of the food delivery mechanism,
the deflection element comprising at least a first semi-annular compression element having an arcuate compression surface situated at a first distance from an axis of rotation of the food delivery mechanism, the abutment element comprising at least a first ledge surface situated on the at least first compression element and having an abutment surface extending a second distance from the axis of rotation of the food delivery mechanism, the second distance being greater than the first distance.
2. The feeding apparatus of claim 1 , wherein
the abutment element comprises a second ledge surface situated on the at least first compression element and having another abutment surface extending a third distance from the axis of rotation of the food delivery mechanism, the third distance being greater than the first distance.
3. The feeding apparatus of claim 2 , wherein
the at least first ledge surface is engageable by the tab upon a rotation of the food delivery mechanism in a first rotational direction, the second ledge surface being engageable by the tab upon a rotation of the food delivery mechanism in a second rotational direction opposite the first direction.
4. The feeding apparatus of claim 1 , wherein
the tab extends a fourth distance from the axis of rotation of the food delivery mechanism, the fourth distance being greater than the first distance but less than the second distance.
