Abstract
In one embodiment, a component for dispensing a fluid includes: a plurality of fluid ejection orifices arrayed in a plane; and an elongated bumper extending along one side of the array generally in a plane intersecting the plane of the array and the bumper having a protruding exterior surface that includes a first part inclining away from the array and a contiguous second part inclining back toward the array.
Claims15
A component for dispensing a fluid, comprising:
- a body having a face and a side intersecting the face;
- a plurality of fluid ejection orifices arrayed in a plane along the face of the body;
- and
- an elongated bumper extending along and protruding from the side of the body along one side of the array generally in a plane intersecting the plane of the array and the bumper having a protruding exterior surface that includes a first part inclining away from the array, a contiguous second part inclining back toward the array, and an apex part connecting the first part and the second part, wherein the apex part points in a direction that is parallel to the plane of the array, and wherein the side of the body intersects the face of the body at a corner and the first part of the exterior surface of the bumper inclines away from the array beginning at or near the corner.

A component for dispensing a fluid, comprising:
- a body having a face and a side generally perpendicular to the face, wherein the face extends along a plane;
- a plate affixed to the face defining an array of fluid ejection orifices;
- and
- a bumper extending along and protruding from the side of the body, the bumper having an exterior surface that includes a first part inclining away from the side, a contiguous second part inclining back toward the side, and an apex part connecting the first part and the second part, wherein the apex part points in a direction that is parallel to the plane of the face, the body also having a cavity located in the side of the body adjacent to and extending lengthwise along the second part of the exterior surface of the bumper.

A component for dispensing a fluid, comprising:
- a body having a face defining an array of fluid ejection orifices and a side intersecting the face;
- and
- an elongated bumper extending along the side of the body, the bumper having a dihedral angled exterior surface protruding from the side of the body, wherein the dihedral angled exterior surface includes a first part inclining away from the array, a contiguous second part inclining back toward the array, and an apex part connecting the first part and the second part, wherein the apex part points in a direction that is parallel to the plane of the array, and wherein the first part of the exterior surface of the bumper inclines away from the array beginning at a location substantially contiguous with the intersection of the face of the body and the side of the body.
An inkjet printhead assembly, comprising:
- a body having a cavity;
- a orifice plate affixed to the body, the orifice plate having an array of ink ejection orifices therein exposed at a generally rectangular face on the body, wherein the orifice plate extends along a plane;
- and
- an elongated bulbous protrusion fronting one side of the face, the protrusion having a lengthwise dimension extending along the side of the face, a lateral dimension generally perpendicular to the lengthwise dimension, and an exterior surface that includes, along the lateral dimension, a first part inclining away from the side of the face, a contiguous second part inclining back toward the side of the face, and an apex part connecting the first part and the second part, wherein the apex part points in a direction that is parallel to the plane of the orifice plate, wherein the cavity of the body adjoins the second part of the exterior surface of the bumper.
