Abstract
A door and drawer front particularly for use in clean-rooms has an outer member and a recessed area having a top grasping surface and a bottom grasping surface extending back into the outer member. A cleaning access area is also provided. The intersections and corners of the member, the recess and the grasping surfaces forming rounded junctions to facilitate easy cleaning and disinfecting of the door and drawer front.
Claims13
A readily cleanable pull for a front surface of a drawer or door, comprising:
- a recessed area extending into the front surface, the recessed area having top, bottom, left, right, and rear recess surfaces;
- a downwardly extending protrusion between the top recess surface and the front surface, extending between the left and right recess surfaces, the downwardly extending protrusion having a front portion coplanar with the front surface, a back portion sloping toward the rear recess surface, and a rounded apex between the front and back portions;
- and
- an upwardly extending protrusion between the bottom recess surface and the front surface, disposed between the left and right recess surfaces but not in contact with at least one of the left and right recess surfaces thereby forming at least one cleaning access portion comprising a section of the junction between the front surface and the bottom recess surface having no upwardly extending protrusion, the upwardly extending protrusion having a front portion coplanar with the front surface, a back portion sloping toward the rear recess surface, and a rounded apex between the front and rear portions;
- the junctions and corners between adjacent surfaces being rounded to facilitate cleaning and disinfection.

A readily cleanable front for a drawer or door, comprising:
- an outer member having at least two adjacent panels disposed one above another, each of the panels having front, top, bottom, left, and right outer surfaces;
- the top and bottom outer surfaces between adjacent panels being abbreviated and connected together by a recessed connecting and torsional strengthening surface;
- and
- the left and right outer surfaces of adjacent panels each being continuous but abbreviated to form a junction with the recessed connecting and torsional strengthening surface;
- a recessed area extending into the front outer surface of one of the panels, the recessed area having top, bottom, left, right, and rear recess surfaces;
- a downwardly extending protrusion between the top recess surface and the front outer surface, extending between the left and right recess surfaces, the downwardly extending protrusion having a front portion coplanar with the front outer surface, a back portion sloping toward the rear recess surface, and a rounded apex between the front and back portions;
- and
- an upwardly extending protrusion between the bottom recess surface and the front outer surface, disposed between the left and right recess surfaces but not in contact with at least one of the left and right recess surfaces thereby forming at least one cleaning access portion comprising a section of the junction between the front outer surface and the bottom recess surface having no upwardly extending protrusion, the upwardly extending protrusion having a front portion coplanar with the front outer surface, a back portion sloping toward the rear recess surface, and a rounded apex between the front and rear portions;
- the junctions and corners between adjacent surfaces being rounded to facilitate cleaning and disinfection.
