Abstract
A gasket for a demountable joint of an hygienic food processing system, the gasket comprising a surface for providing a smooth transition from a first joint part to a second joint part at a joint. The sides of a preferred embodiment gasket each define a plateau adjacent the surface for abutting the joint parts which, in use, produce a hygienic seal. The gasket of the present invention in preferably made from a plastics material having sufficient structural strength(i.e. engineering plastics) which, even when not fully supported to withstand pressures and/or temperatures, during use maintain the hygienic performance of the joint.
Claims26
An apparatus for use in a hygienic food processing system, comprising:
- a gasket made substantially of engineering plastics material, wherein said engineering plastics material is selected to be resistant to creep during said gasket's use in said hygienic food processing system, wherein the gasket comprises:
- a surface for providing a smooth transition from a first joint part to a second joint part at a demountable joint of said hypienic food processing system;
- and
- a side defining a plateau, adjacent the surface, for abutting at least one of said first and second joint parts, wherein said plateau is positioned on a nib which extends from a body of the gasket, which in use produces an hygienic seal.
A pipe joint of an hygienic food processing system comprising:
- a first pipe end;
- a second pipe end;
- and
- a gasket having nibs disposed annular to and adjacent a bore hole of said gasket, wherein said nibs are compressed between the first and second pipe ends substantially at a pipe bore such that deformation of the nibs results in an hygienic seal being produced between the gasket and the first and second pipe ends, wherein said gasket is made substantially of engineering plastics material, wherein said engineering plastics material is selected to be resistant to creep during said gasket's use in said hygienic food processing system.
