Abstract
Official abstract text for this publication.
A sealing system for food applications that provides a housing element with two or more bolts and respective holes for clamping. A flanged element is clamped to a frame of a machine, and a rubber seal placed along the base perimeter of the housing element. The seal includes a first portion of the rubber profile placed in the areas distant from the holes and a second portion of the rubber profile adjacent to the holes. The rubber profile of the second portion has a larger cross section than that of the first portion, such that the deformations of the rubber profile are made virtually uniform to prevent the formation of fractures, and therefore of bacteria traps, in the rubber.
First claim
Opening claim text (preview).
What is claimed is: 1. A sealing system for food applications comprising: a housing element comprising two or more clamping holes, each clamping hole configured to receive a bolt to clamp the housing element to a frame of a machine, and a rubber seal comprising a rubber profile arranged along an outer base perimeter of the housing element and having a cross-section, and wherein the rubber seal includes a first portion of the rubber profile arranged at the outer base perimeter of the housing element and located in an area away from the holes, and a second portion of the rubber profile arranged at the outer base perimeter of the housing element and located in an area adjacent to the holes, wherein the cross-section of the rubber profile is not constant along the outer base perimeter of the housing element, wherein the rubber profile of the second portion has a cross-section greater than the cross-section of the first portion to make deformations of the rubber profile uniform along the outer base perimeter of the housing element to prevent formation of fractures. 2. The system according to claim 1 , wherein a ratio between a thickness of the second portion of the rubber profile and a thickness of the first portion of the rubber profile ranges between 1.25 and 1.80. 3. The system according to claim 1 , wherein the rubber profile of the rubber seal comprises a transition section having a cross-section gradually decreasing away from the area adjacent to the holes of the housing element. 4. The system according to claim 1 , wherein the rubber seal presents a hardness approximately equal to 70 Shore A. 5. The system according to claim 1 , wherein the rubber seal is non-unitary with the housing element.
